I have been using a BNO055 sensor (9° dof IMU) for a project which will use angular velocity to move the mouse cursor on a PC screen.
So far, I have gotten quaternion output from the sensor and been able to convert it to angular velocity in a couple of ways. The first, multiplying 1 quaternion sample by its conjugate in the next sample, and then converting the quaternion Delta in Euler angles. The second, converting from quaternions to Euler angles and then finding the change in those between samples.
Both methods result in angular velocity measurement, but each with their advantages and disadvantages. E.g. Quaternion Delta between samples does not suffer from gimbal lock, but it's difficult to isolate pitch from roll.
I know that you can ask the sensor for angular velocity data directly, but apparently that's less precise due to the Gyro drift and it's relative orientation only, which is why I opted to work with quaternions.
Is there a better way to go about this?
My code included below for reference with the 2 approaches in case it's helpful/interesting. It uses the Adafruit repository for BNO sensor.
void quaternion_Delta () {
 // Quaternion data 1
 imu::Quaternion quat = bno.getQuat();
 // Euler 1
 imu::Vector<3> euler_one = quat.toEuler();
 //delay between samples
 // Quaternion data 2
 imu::Quaternion quat_two = bno.getQuat();
 // Euler 2
 imu::Vector<3> euler_two = quat_two.toEuler();
 // quaternion comparison
 imu::Quaternion quatDelta = quat_two * quat.conjugate ();
 imu::Vector<3> euler = quatDelta.toEuler();
 Serial.print(" X: ");
 Serial.print(euler.x()*radius_to_degrees, 2);
 Serial.print(" Y: ");
 Serial.print(euler.y()*radius_to_degrees, 2);
 Serial.print(" Z: ");
 Serial.print(euler.z()*radius_to_degrees, 2);
 // Euler comparison
 imu::Vector<3> euler_comparison = euler_two - euler_one;
 Serial.print(" x: ");
 Serial.print(euler_comparison.x()*radius_to_degrees, 2);
 Serial.print(" y: ");
 Serial.print(euler_comparison.y()*radius_to_degrees, 2);
 Serial.print(" z: ");
 Serial.print(euler_comparison.z()*radius_to_degrees, 2);
Edit: demonstration for quaternion Delta.
When quaternion current * quaternion home and transforming to Euler angles, we get the angular velocity between the 2 quaternions. Please imagine the sheet of paper to be the earth reference frame and to the watch the sensor's reference frame. With no yaw rotation, if with tilt the sensor up that causes a positive change in the y (pitch) axis. With 90° rotation of the sensor in the X (yaw) axis, however, a tilt of the sensor results in a change in the z (roll) axis instead.
My understanding is that this happens because quaternions are a representation of absolute orientation. So with any angle of rotation in the yaw axis we get a mixture of change in the pitch and roll axis whenever we tilt the sensor up or down.
This is what I mean that a change in sensor tilt (moving it up or down) results in a change in either/both the Y and Z axis.

 \$\begingroup\$ Can you show an example where it is difficult to isolate pitch from roll? I would also like to know why drift is an issue when using the rates directly from the IMU. \$\endgroup\$ – AJN Apr 23 at 12:59
 - \$\begingroup\$ I will edit my post with some pictures and explanation. With regards to the gyroscope drift, I'm not exactly sure if that happens or not. I just read that it is an issue if using only the gyroscope to detect angular velocity and that is why you would prefer to have sensor fusion. Maybe that is not the case and I misunderstood something? \$\endgroup\$ – Zhelyazko Grudov Apr 23 at 13:30
... which will use angular velocity to move the mouse cursor on a PC screen.
It is not clear if the angular velocity will control the cursor velocity or the cursor position. If the angular velocity is controlling the cursor velocity, then the cursor position will be affected by drift (due to the integration operation performed). However, this can be solved in software by passing the sensed angular velocity through a threshold operation (dead zone). The threshold is chosen to be more than the expected drift.
quaternion current * quaternion home and...
The first statement gives the impression that the IMU output is sampled with small time intervals and you are using the adjacent samples of quaternion. If this is the case, the angle between the two quaternion will be a small angle and the pitch/roll mixing problem doesn't arise (for sufficiently small sampling interval).
The second statement gives the impression that the current quaternion is multiplied with the very first sampled quaternion or a fixed home quaternion and not the immediately preceding sample. The angles between the quaternion can be large and pitch/roll mixing will occur.
... quaternion current * quaternion home and transforming to Euler angles, we get the angular velocity between the 2 quaternion.
No. we get the angle (or rotation) between the two quaternion. If we took the difference between two displacements, the result is also a displacement and not a linear velocity. If the two displacements were measured a very very small time apart and if you divided the difference by the time, then, that quantity is a (instantaneous) linear velocity. If the time gap was large, the quantity is average velocity.
For rotations, when the angle difference is large, we can still compute the average angular velocity by imagining the shortest rotation which will take one quaternion to the other. However, due to the inherent properties of rotation, you cannot avoid mixing between the channels.
Reconstructing the angular velocity from quaternion
Using the quaternion to reconstruct the angular velocity may still be a good idea since the IMU software might have used the accelerometers or magnetometers to cancel the drift in the angular velocity measurement.
From the linked answer, we have, by rearranging,
$$ \left[\begin{matrix} -q_x(t) & -q_y(t) & -q_z(t) \\ q_w(t) & q_z(t) & -q_y(t) \\ -q_z(t) & q_w(t) & q_x(t) \\ q_y(t) & -q_x(t) & q_w(t) \end{matrix} \right]^{-1} \frac{2}{\delta t} \left( \left(\begin{matrix}q_w(t+\delta t) \\ q_x(t+\delta t) \\ q_y(t+\delta t) \\ q_z(t+\delta t) \end{matrix}\right) - \left(\begin{matrix}q_w(t) \\ q_x(t) \\ q_y(t) \\ q_z(t) \end{matrix}\right) \right) = \left(\begin{matrix} \omega_x(t) \\ \omega_y(t) \\ \omega_z(t) \end{matrix} \right). $$
If I am not mistaken (be careful about the quaternion convention. Some use frame representation, some use rotation operator representation), the result will be in the frame of the IMU platform. You can convert this vector to the home axis frame by using the vector rotation formula.
 - \$\begingroup\$ Thank you for the detailed answer. I'll have a look through it and try to implement. \$\endgroup\$ – Zhelyazko Grudov Apr 23 at 18:30
 - \$\begingroup\$ I've been working on this project for the last couple of months. Just went over this answer again and realized how much of it went over my head. Thank you for taking the time. I'm still having trouble reconstructing the angular velocity from quaternions, or finding a way to work around pitch/roll mixing. Not sure if appropriate, but would you be willing/available for a paid consultation? \$\endgroup\$ – Zhelyazko Grudov May 18 at 8:48
 - \$\begingroup\$ Thanks for responding. I will post a new question, and see how it goes. \$\endgroup\$ – Zhelyazko Grudov May 18 at 13:03

MODUNLOAD(8) Maintenance Commands and Procedures MODUNLOAD(8)
modunload - unload a module
modunload -i module_id [-e exec_file]
modunload unloads a loadable module from the running system. The module_id is the ID of the module as shown by modinfo(8). If ID is 0, all modules that were autoloaded which are unloadable, are unloaded. Modules loaded by modload(8) are not affected.
The following options are supported:
-e exec_file
Specify the name of a shell script or executable image file to be executed before the module is unloaded. The first argument passed is the module id (in decimal). There are two additional arguments that are module specific. For loadable drivers, the second argument is the driver major number. For loadable system calls, the second argument is the system call number. For loadable exec classes, the second argument is the index into the execsw table. For loadable filesystems, the second argument is the index into the vfssw table. For loadable streams modules, the second argument is the index into the fmodsw table. For loadable scheduling classes, the second argument is the index into the class array. Minus one is passed for an argument that does not apply.
-i module_id
Specify the module to be unloaded.
attributes(7), modinfo(8), modload(8), update_drv(8)
The modunload command is often used on driver modules to force the system to reread the associated driver configuration file. While this works in the current Solaris release, it is not the supported way to reread the configuration file and is not guaranteed to work in future releases. The supported way for rereading driver configuration file is through the update_drv(8) command.

Support > Repository > Screen function > Button name and display condition
ja | en
You can change the names and display conditions of the buttons prepared for each screen. Expressions are also applicable.
Figures 1 and 2 show examples of applying expressions to button names.The button name will change depending on the logon account.
Figure 1 When the system administrator uses it, the button name becomes "administrator registration"
Figure 2 When the general use is used, the button name becomes "general registration"
Not only the fixed name but also the expression can be set for the "button name" of "button display" prepared for each screen.
Fig. 3 Button name setting
When specifying a fixed name
Specify the button name as it is.
Schedule registration
When using formula
Make sure the result type of the expression calculation result is of type string type.
IF (EXACT (USERNAME (), "admin"), "administrator registration", "general registration")
For details of the formula, see "a formulaPlease read.
When "button display condition" is set, the button will be displayed on the screen only when the condition is met.Figure 4 shows an example of specifying the condition "Date is after today".
DATE(${sdate})>=DATE(TODAY())
The return value of the expression should be a boolean value.trueOrfalseI will try to return.
Figure 4 Applied date condition
Control display/non-display of the button in conjunction with the value of the condition item
In the example of Figure 4, if you do not match the conditions when opening the new registration screen, the registration button will be hidden.After that, even if you enter a conditional date item, the button will remain hidden.
In the case of modifying this operation and controlling display/non-display of the button in conjunction with the value of the condition item, as shown in FIG. 5 (regarding the condition item) "When the value is changed, the screen is re-displayed Drawing "setting is effective.
When this setting is made, the value of the form will be retransmitted each time the value of the item is changed.Control of button display judgment is performed on the server side.
Figure 5 Redrawing screen when changing value
Example of description of conditional expression
When the value of the item item is 1, the registration button is displayed
${item}==1
When the value of the item item is "Tokyo", the registration button is displayed
EXACT ($ {item}, "Tokyo")
EXACTThe function compares strings.
For the model schedule, display a button when a user who has the authority "perm_button" operates it
HASMODELPERMISSION("perm_button", "schedule")
HASMODELPERMISSIONThe function returns whether it has the authority specified by the user.
Display a button when a user who has a principal "publicuser" operates it
HASPRINCIPAL("publicuser")
Administrator only Display buttons
HASPRINCIPAL("all")
All means administrator authority.
When you log on with administrator privileges,HASPRINCIPAL Function alwaystrue.Therefore, in the case of displaying only button of administrator authority, it means that any argument (principal name) given in parentheses is actually anything.However, to distinguish it from other principals, we recommend specifying all as above.
With foreign key relationships, you can list multiple child models on the screen of the parent model.
The button display control in this case is the following rule.
 - Items that can be included in conditional expressions areParent model.
 - However, the notation "child model _lp" can be used as a list display of children as seen from the parent.
Example: "Foreign key cooperation> Display condition"And the value of the item item 1 of the parent model is larger than 100, a new registration button of the child model is displayed.
${item1} > 100
Example: When the number of child models linked to this parent model is less than 3, display the registration button of the child model.
COUNT(${support_lp} < 3)
COUNTThe function returns the total number of child records.
Fig. 6 Button display control by external key cooperation
It also shows an example of controlling button names with expressions.Button name changes according to the number of child models.
IF (COUNT ($ {support_lp}) == 2, "one more", IF (COUNT ($ {support_lp} == 1, "two more", "three more"))
Restriction
This specification is not reflected on the "New" button on the child model list maintenance screen.
(The control of "New" button on the list update screen is currently unsupported.)

text: Forced commutated cycloconverters (PWM cyclo-converters) have no energy storage components except for small ac filters for the elimination of switching ripples. Therefore, the PWM cycloconverters can be made compact and highly reliable compared with the conventional converter-inverter systems. The PWM cycloconverters, however, directly connected the input terminals to the output terminals by the switching devices. As a result, if the input source voltages are asymmetrical and/or contain harmonics, the influence of the distortions directly appear on the output terminals. This problem is a major obstacle to using PWM cycloconverters instead of the conventional converter-inverter systems. This paper presents a novel control method for PWM cycloconverters. By using this control method, sinusoidal input and output current waveforms and unity input displacement factor can be obtained. Moreover, the compensation of the asymmetrical and/or harmonic contaminated input source voltages is easily realized.

text: A novel signaling scheme for iterative channel estimation and data decoding is proposed. In the proposed scheme, the occurrence probability of transmitted symbols is biased. A priori information about the bias is utilized for the initial channel estimation. The proposed scheme is based on parallel concatenation of two biased convolutional codes (BCCs), which are constructed as systematic recursive convolutional codes with state-dependent puncturing. The BCCs can be regarded as a joint coding scheme that determines the insertion positions of pilot symbols according to information bits. The proposed scheme is numerically shown to outperform conventional pilot-based schemes in the waterfall region, while it is inferior to the conventional schemes in the error-floor region.


b cli setup or by explicitly setting the HAB_ORIGIN and HAB_ORIGIN_KEYS environment variables, then type the following:
 $ hab studio enter
 The directory you were in is now mounted as /src inside the Studio. By default, a Supervisor runs in the background for iterative testing. You can see the streaming output by running sup-log. Type Ctrl-C to exit the streaming output and sup-term to terminate the background Supervisor. If you terminate the background Supervisor, then running sup-run will restart it along with every service that was previously loaded. You have to explicitly run hab svc unload origin/package to remove a package from the "loaded" list.
 3. Enter the following command to create the package.
 $ build /src/planname
 4. If the package builds successfully, it is placed into a results directory at the same level as your plan.
Managing the Studio Type (Docker/Linux/Windows)
Depending on the platform of your host and your Docker configuration, the behavior of hab studio enter may vary. Here is the default behavior listed by host platform:
 - Linux - A local chrooted Linux Studio. You can force a Docker based studio by adding the -D flag to the hab studio enter command.
 - Mac - A Docker container based Linux Studio
 - Windows - A local Windows studio. You can force a Docker based studio by adding the -D flag to the hab studio enter command. The platform of the spawned container depends on the mode your Docker service is running, which can be toggled between Linux Containers and Windows Containers. Make sure your Docker service is running in the correct mode for the kind of studio you wish to enter.
Note: For more details related to Windows containers see Running Chef Habitat Windows Containers.
Building Dependent Plans in the Studio
Writing plans for multiple packages that are dependent on each other can prove cumbersome when using multiple studios, as you need update dependencies frequently. On the other hand, using a single studio allows you to quickly test your changes by using locally built packages. To do so, you should use a folder structure like this:
$ tree projects
projects/
├── project-a
└── project-b
This way, you can hab studio enter in projects/. If project-b depends on project-a, you can call build project-a && build project-b for example.
Non-interactive Build
A non-interactive build is one in which Chef Habitat creates a Studio for you, builds the package inside it, and then destroys the Studio, leaving the resulting .hart on your computer. Use a non-interactive build when you are sure the build will succeed, or in conjunction with a continuous integration system.
 1. Change to the parent directory of the plan context.
 2. Build the artifact in an unattended fashion, passing the name of the origin key to the command.
 $ hab pkg build yourpackage -k yourname
 Similar to the hab studio enter command above, the type of studio where the build runs is determined by your host platform and hab pkg build takes the same -D flag to force a Docker environment if desired.
 3. The resulting artifact is inside a directory called results, along with any build logs and a build report (last_build.env) that includes machine-parsable metadata about the build.
By default, the Studio is reset to a clean state after the package is built; however, if you are using the Linux version of hab, you can reuse a previous Studio when building your package by specifying the -R option when calling the hab pkg build subcommand.
For information on the contents of an installed package, see Package Contents.
Troubleshooting Builds
Bash Plans: attach
While working on plans, you may wish to stop the build and inspect the environment at any point during a build phase (e.g. download, build, unpack, etc.). In Bash-based plans, Chef Habitat provides an attach function for use in your plan.sh that functions like a debugging breakpoint and provides an easy REPL at that point. For PowerShell-based plans, you can use the PowerShell built-in Set-PSBreakpoint cmdlet prior to running your build.
To use attach, insert it into your plan at the point where you would like to use it, e.g.
do_build() {
attach
make
}
Now, perform a build -- we recommend using an interactive studio so you do not need to set up the environment from scratch for every build.
$ hab studio enter
$ build yourapp
The build system will proceed until the point where the attach function is invoked, and then drop you into a limited shell:
### Attaching to debugging session
From: /src/yourapp/plan.sh @ line 15 :
5: pkg_maintainer="The Chef Habitat Maintainers <_EMAIL_>"
6: pkg_source=_URL_
7: pkg_shasum=c2a791c4ea3bb7268795c45c6321fa5abcc24457178373e6a6e3be6372737f23

13: )
14:
15: do_build() {
=> 16: attach
17: make
18: }
[1] yourapp(do_build)>
You can use basic Linux commands like ls in this environment. You can also use the help command the Chef Habitat build system provides in this context to see what other functions can help you debug the plan.
[1] yourapp(do_build)> help
Help
help Show a list of command or information about a specific command.
Context
whereami Show the code surrounding the current context
(add a number to increase the lines of context).
Environment
vars Prints all the environment variables that are currently in scope.
Navigating
exit Pop to the previous context.
exit-program End the /hab/pkgs/core/hab-plan-build/0.6.0/20160604180818/bin/hab-plan-build program.
Aliases
@ Alias for whereami.
quit Alias for exit.
quit-program Alias for exit-program.
Type quit when you are done with the debugger, and the remainder of the build will continue. If you wish to abort the build entirely, type quit-program.
PowerShell Plans: Set-PSBreakpoint
While there is no attach function exposed in a plan.ps1 file, one can use the native Powershell cmdlet Set-PSBreakpoint to access virtually the same functionality. Instead of adding attach to your Invoke-Build function, enter the following from inside your studio shell:
[HAB-STUDIO] Habitat:\src> Set-PSBreakpoint -Command Invoke-Build
Now upon running build you should enter an interactive prompt inside the context of the Invoke-Build function:
habitat-aspnet-sample: Building
Entering debug mode. Use h or ? for help.
Hit Command breakpoint on 'Invoke-Build'
At C:\src\habitat\plan.ps1:26 char:23
+ function Invoke-Build {
+ ~
[HAB-STUDIO] C:\hab\cache\src\habitat-aspnet-sample-0.2.0>>
You can now call Powershell commands to inspect variables (like Get-ChildItem variable:\) or files to debug your build.
Package Export Formats
You can export packages into several different external, immutable runtime formats. This topic will be updated as more formats are supported in the future. Currently there are exports for: docker, ACI, mesos, tar, and cloudfoundry.
The command to export a package is hab pkg export <FORMAT> <PKG_IDENT>. See the Chef Habitat CLI Reference Guide for more CLI information.
Note If you specify an origin/package identifier, such as core/postgresql, the Chef Habitat CLI will check Builder for the latest stable version of the package and export that.
If you wish to export a package that is not on Builder, create a Chef Habitat artifact by running the build command, then point hab pkg to the .hart file within the /results directory:
hab pkg export tar ./results/example-app.hart
Read on for more detailed instructions.
Exporting to Docker
You can create a Docker container image for any package by performing the following steps:
 1. Ensure you have a Docker daemon running on your host system. On Linux, the exporter shares the Docker socket (unix:///var/run/docker.sock) into the studio.
 2. Create an interactive studio with the hab studio enter command.
 3. Build the Chef Habitat package from which you want to create a Docker container image and then run the Docker exporter on the package.
 $ hab pkg export docker ./results/<hart-filename>.hart
 Note The command above is for local

, insert dummy data, and upgrade that.
If you are upgrading a pre-PostgreSQL 9.2 cluster that uses a configuration-file-only directory, you must pass the real data directory location to pg_upgrade, and pass the configuration directory location to the server, e.g., -d /real-data-directory -o '-D /configuration-directory'.
If using a pre-9.1 old server that is using a non-default Unix-domain socket directory or a default that differs from the default of the new cluster, set PGHOST to point to the old server's socket location. (This is not relevant on Windows.)
If you want to use link mode and you do not want your old cluster to be modified when the new cluster is started, make a copy of the old cluster and upgrade that in link mode. To make a valid copy of the old cluster, use rsync to create a dirty copy of the old cluster while the server is running, then shut down the old server and run rsync --checksum again to update the copy with any changes to make it consistent. (--checksum is necessary because rsync only has file modification-time granularity of one second.) You might want to exclude some files, e.g., postmaster.pid, as documented in Section 24.3.3. If your file system supports file system snapshots or copy-on-write file copies, you can use that to make a backup of the old cluster and tablespaces, though the snapshot and copies must be created simultaneously or while the database server is down.

This paper presents the transformer-based multilevel inverter-fed induction motor drive. The development of new technology of power electronic switches and control techniques for inverter-based speed control of induction motor has led to the usage of induction motor in industrial and domestic applications. In this work, the stator winding of induction motor is fed through proposed five-level transformer-based symmetrical inverter, which consists of unidirectional and bidirectional switches, mid-point transformer and capacitors as voltage divider network to produce multilevel output voltage at the load side. The speed of the induction motor is varied by changing supply voltage of an induction motor by adjusting width of the pulse width-modulated signal. A speed controller has been implemented through fuzzy logic controller for performing closed loop operation of single phase induction motor drive. The ability of fuzzy-based speed controller can reduce the undesirable sustained oscillations in speed of induction motor drive and also provide better machine performance than conventional linear controller. The proposed controller performance of multilevel inverter-fed induction motor drive system is validated through MATLAB simulink environment.

tooth comb. Applying a small amount of leave-in conditioner or hair oil can also help to smooth the hair and reduce frizz, giving your braid a more polished appearance.
Using a Mirror and Proper Lighting
French braiding can be a bit tricky, especially when braiding the back of your head. To make the process easier and ensure a neater result, work in front of a mirror. Position the mirror in such a way that you can see both the front and the back of your head. Adequate lighting is also crucial for precision braiding. Natural light or a well-lit room will help you see the sections clearly and avoid any mistakes.
Keeping the Sections Evenly Sized
Maintaining consistent and evenly sized sections is essential for creating a well-balanced and symmetrical French braid. To achieve this, use your fingers or a comb to divide your hair into distinct sections, ensuring that they are of equal thickness. This will help to create a more uniform and professional-looking braid.
Maintaining Tension and Consistency
To achieve a polished and secure French braid, it's important to maintain consistent tension throughout the braid. Apply gentle pressure to the strands as you add hair to each crossover, ensuring that they are held firmly but not too tightly. This will help to create a braid that stays in place without pulling or causing discomfort.
Making Adjustments as You Braid
Don't be afraid to make adjustments as you go along. If you notice any loose sections or unevenness in the braid, simply undo the last few crossovers and reposition the strands. Take your time and be patient throughout the process. Remember, practice makes perfect, and the more you practice, the better you'll become at achieving a neat and professional-looking French braid.
Fixing Common French Braiding Mistakes
Fixing Loose Sections
If you notice loose sections in your French braid, don't panic. Simply undo the loose section, add a small amount of hair gel or hairspray to the hair, and re-braid it, making sure to hold the strands tightly. This will help to create a more secure and uniform braid.
Tightening Loose Braid
If your French braid feels loose overall, it may be because the strands were not held tightly enough while braiding. To fix this, carefully undo the entire braid and start again, paying closer attention to the tension you apply to the strands and the amount of hair you add at each crossover. By being more mindful of these factors, you can achieve a tighter and more secure French braid.
Repositioning Misaligned Braid
Sometimes, during the French braiding process, the braid can shift to one side or become misaligned. To correct this, gently undo the previous few crossovers and reposition the strands to create a centered and symmetrical braid. Making these small adjustments as you go along will help to maintain a neat and balanced appearance.
Recovering from Hair Slippage
If your hair tends to slip out of the braid as you're braiding, it may be helpful to use bobby pins to secure the strands in place. Insert the bobby pins along the direction of the braid, catching any loose strands and pinning them down. This will help to keep your hair in place and prevent slippage.
Refining the Appearance of the Braid
To give your French braid a more refined and polished look, use a comb to carefully pull on the outer edges of the braid. Gently tug on the strands to widen the braid and create a fuller appearance. This technique can help to make your French braid appear larger and more voluminous, adding an extra touch of elegance to your hairstyle.
Decorating and Styling French Braids
Adding Hair Accessories
Hair accessories can be a fun and stylish way to enhance the appearance of your French braid. Options such as decorative hairpins, flowers, or jeweled clips can be strategically placed along the braid to add a touch of glamour. Ensure that the accessories you choose complement your overall look and match the occasion.
Incorporating Ribbons or Scarves
For a bohemian or whimsical vibe, consider incorporating ribbons or scarves into your French braid. Begin the braid as usual and then weave a colorful ribbon or scarf into the strands as you continue braiding. This will add a pop of color and unique texture to your braid, making it stand out in a crowd.
Wrapping the Braid into a Bun or Updo
A French braid can serve as the foundation for many stunning updo hairstyles. Once you've completed the braid, gently wrap it around itself to create a bun at the nape of your neck. Secure it with bobby pins, tucking away any loose ends. This elegant and sophisticated updo is perfect for special occasions or when you want to elevate your French braid to the next level.
Creating Braided Pigtails
Braided pigtails are a fun and youthful way to style your French braid. Start by creating two French braids on either side of your head, starting from the front and working your way towards the back. Once the braids are complete, secure them with hair ties at the ends. This playful hairstyle is perfect for casual outings or when you want to add a touch of playfulness to your look.
Maintaining and Extending the Lifespan of French Braids
Securing the Braid for Durability
To ensure that your French braid stays in place throughout the day, it's important to secure it properly. Begin by tying the end of the braid tightly with a hair tie. Then, apply a small amount of hairspray to the braid to offer extra hold and prevent any flyaways. If necessary, use bobby pins to secure any loose strands or sections for added durability.
Protecting the Braid Overnight
To preserve your French braid overnight and prevent it from getting messy or undone, consider wrapping it in a silk or satin scarf before going to bed. This will help to reduce friction and prevent the braid from rubbing against your pillow, preserving its integrity and appearance.
Refreshing the Braid with Dry Shampoo
If your French braid starts to look a bit limp or greasy, dry shampoo can be your best friend. Spritz a small amount of dry shampoo onto the roots of your braid and gently massage it into your scalp. This will help to absorb excess oil and give your braid a fresh and rejuvenated appearance.
Reviving the Braid with Additional Styling
If your French braid starts to loosen or lose its shape throughout the day, you can easily revive it with a few additional styling techniques. Start by gently re-braiding any loose sections, incorporating a small amount of hairspray or hair gel for added hold. You can also use bobby pins to tuck away any loose strands and adjust the shape of the braid. These small touch-ups will help to ensure that your French braid looks flawless and polished all day long.
Final Tips for Becoming a French Braiding Pro
As with any skill, practice is key to becoming a French braiding pro. Set aside dedicated time to practice your French braiding technique, starting with simple styles and gradually working your way up to more complex variations. The more you practice, the more comfortable and confident you will become in creating beautiful French braids.
Watching Online Tutorials
In addition to regular practice, watching online tutorials can be incredibly helpful in improving your French braiding skills. There are numerous video tutorials available that break down the steps and provide visual guidance. Take advantage of these resources to learn new techniques, pick up tips and tricks, and refine your French braiding abilities.
Experimenting with Different Techniques

Jejunoileal bypasses were performed in rats to determine the effect of improved absorption on the development of liver dysfunction occurring after this procedure. Several parameters of liver function were measured in rats 7 weeks after both the standard 85% small-bowel, bypass and an 80% bypass in which an extra 5 cm of intact bowel was retained. Animals having undergone 80% bypass had a lesser degree of lowering of serum protein and triglyceride levels, hepatic cytochrome P-450 content, and hepatic glucose-6-phosphatase activity than did the animals undergoing 85% bypass. Abnormalities found in 85% bypassed animals were only partially reproduced by reducing food intake in another group of 80% bypassed animals. These findings emphasize the importance of, nutritional factors in the etiology of bypass-induced liver disease and militate against toxin production in the defunctionalized bowel as the sole cause of liver dysfunction following bypass.

Welcome to the website of the Ukrainian Orthodox Church of the Holy Trinity!
Тhe Holy Trinity Church is a part of the Ukrainian Orthodox Church of Canada. We are located in London, Ontario. Services are conducted in Ukrainian. To learn more about the history of the Ukrainian Orthodox Church of Canada.-
THE CELEBRATION OF THE HOLY TRINITY
The Ukrainian Orthodox Church of Canada, by clearly communicating Her teachings and values to us, Her faithful, as individuals and as a community, will foster an environment of love and caring that will challenge us to pursue our fundamental human calling of deification – the process by which human persons grow God-like.
Our church is dedicated to the Holy Trinity. The Holy Trinity Feast Day is celebrated on the fiftieth day after Holy Easter. On the day after, is the Feast of The Holy Spirit. According to the Gospel, on this day the fire of the Holy Spirit came down upon the disciples of Jesus and they began to preach and bear witness to Jesus as the risen Christ, the King and the Lord. This moment has traditionally been called the birthday of the Church. For Ukrainians this feast day is also called Zeleni Svyata. In Orthodox tradition, the church khram is decorated with flowers and the green leaves of spring to show that God's divine breath comes to renew all creation. Green vestments are used. A Divine Hierarchical Liturgy is celebrated if His Grace, our Bishop of Eastern Canada, officiates. The events of the day include a Feast Day Dinner and a special program. On this day our parish welcomes many guests from within the city and beyond.
Our church parish was formed in 1950 by post World War II immigrants to Canada who wished to continue their Orthodox Church traditions in freedom. Construction of a church building was started in 1960, and completed in 1964. The consecration was officiated by His Eminence, Metropolitan Ilarion of Canada and Right Rev. Archbishop Michael of Toronto.
We include in our members and welcome all persons of the Orthodox faith. Now new immigrants and descendants of our founding members worship side by side. Services are conducted primarily in Ukrainian with some English and the responses are sung by a choir in the Kyivan tradition. At present, our services are on a part-time basis.

A new exhibition celebrating Plymouth's civil engineering heritage has opened on the University of Plymouth campus.
The Lighthouses, Bridges and Breakwaters exhibition in the Sherwell Centre hopes to inspire future engineers by highlighting the city's groundbreaking engineering works – both historic and modern.
It features information panels exploring the original construction of the iconic Smeaton's Tower Lighthouse, Tamar Bridge and Plymouth Breakwater, as well as modern changes like the innovative 2002 bridge widening.
It also shines a light on modern research currently being undertaken at the University of Plymouth's COAST Lab, which uses computer modelling to predict wave patterns.
Professor Deborah Greaves, head of the university's school of engineering, said the exhibit was "an opportunity to inspire current and prospective students, and our many thousands of graduates, and to demonstrate what an education in engineering can enable them to achieve".
The exhibition marks the 200th anniversary of the founding of the Institution of Civil Engineers (ICE) and coincides with the 2018 Year of Engineering.
It is also part of Plymouth Museum's Museum on Tour programme, getting exhibits out and about while the Museum and Art Gallery building is being redeveloped.
Cllr Glenn Jordan, Plymouth cabinet member for culture, said: "This is an important anniversary to commemorate and an exciting time to find out about all the things that will help shape our city and world in the future."
The exhibition runs till March 17. Opening hours are 9am to 6.30pm Monday to Saturday and entry is free. Information on related events can be found at _URL_
With 2018 the Year of Engineering, Plymouth has a whole history of iconic engineering innovation to shout about.
Royal Albert Bridge
When the decision was made to take the West Country railway extension along the coast in the mid-1800's the question was: how to get it over the Tamar River?
An early idea focussed on using the Torpoint Chain Ferry to take the railway across the river. However, this was soon replaced by Isambard Kingdom Brunel's plans for a unique, bow arch self-supporting viaduct at Saltash.
The construction project, which opened in 1859, was a huge success and is still in use today.
Plymouth and Saltash gained another crossing when the Tamar Bridge was built between 1959 and 1961. It was originally designed to handle 20,000 road crossings a day, but by the nineties usage was twice that.
Something needed to be done, but building a new bridge would be time consuming and expensive, and closing the existing bridge to strengthen it would cause major disruption for diverted traffic.
The award-winning solution, carried out between 1999 and 2001, was to add additional lanes to the outside of the bridge so that traffic could continue to cross whilst work was carried out. Once strengthening had been completed, the additional lanes were left for permanent use.
This iconic Plymouth tower was originally built in 1759 as one of four lighthouses marking the dangerous Eddystone Reef out at sea.
It was named after its designer John Smeaton, one of the leading civil engineers of the time, and its inwardly-curved profile gave it extra strength.
But by 1884 the tower was under threat from the eroding and insecure reef beneath it. The decision was made to move it inland, and it remains one of Plymouth's best known landmarks.
In the early 1800's pressure grew to provide Plymouth's naval vessels with a safe base near to their dockyard. The natural harbour was just too dangerous to anchor in.
Work began on the breakwater in 1811-12. Options that would have attached the breakwater to land were rejected in favour of an 'unattached' design that retained the historic shipping routes into Plymouth.
Much of the breakwater sits below the surface, and the angled arms calm the water. The result benefits both naval and maritime ships
Plymouth's links to engineering innovation are not only in the past.
Plymouth University's COAST Lab uses computer modelling to predict wave patterns, as well as researching how renewable wave energy technology can be built into breakwater designs.


a set of sensor values. Then, the value provided for the variable in the Function Parameters box is a Sensor ID:
id_val: Burt158_firing_rate
The id_ prefix on the variable val indicates that the variable will be taken from an existing sensor. Burt158_firing_rate is the Sensor ID of the firing rate sensor.
So, every 30 minutes BMON will gather up all of the Burth158_firing_rate sensor readings that have not already been used previously in this calculation, and BMON will multiply the by 1500 to create additional sensor readings for the Burt158_boiler_gas sensor.
Here is a more complicated example that creates a Calculated Field that estimates the natural gas usage of a sidewalk snowmelt system based on measuring supply and return temperatures and the runtime of a circulating pump:
_images/calc_ex6.png
The Calculated Function being used here is the fluidHeatFlow function, as described in the table above. You can see in the Function Parameters box that the heat_recovery variable is not provided in the configuration of this Calculated Field. Therefore, the heat_recovery variable will assume its default value of 0.0. Three of the variables in the math expression for the fluidHeatFlow function come from existing sensor values: flow, Thot, and Tcold. In the Function Parameter box, these variable names are prefaced by the id_ prefix, indicating the values provided are Sensor IDs. The multiplier variable is not a sensor value but instead the constant 14960.0.
Finally, you can see that the flow variable appears in the Function Parameter box as id_flow_sync. As explained before, the id_ prefix indicates that the variable comes from a Sensor. The _sync suffix indicates that the final calculated values for the new sensor (manor_snw1_gas) should be synchronized on the timestamps of this sensor. The other input sensor values (Thot and Tcold) will be interpolated to these timestamp values when the calculation occurs. If you have multiple sensor values entering into a Calculated Field, you can add the suffix _sync to the variable whose timestamp values should be used for the resulting calculated values. If you do not append _sync to one of the variable names, one of the inputs sensors will be used for synchronization, but it will not be easy to determine which one.

A filtered category is a categorification of the concept of directed set. In addition to having an upper bound (but not necessarily a coproduct) for every pair of objects, there must also be an upper bound (but not necessarily a coequaliser) for every pair of parallel morphisms.
A category whose opposite is filtered is called cofiltered.
Equivalently, filtered categories can be characterized as those categories where, for every finite diagram, the diagonal functor is final. This point of view can be generalized to other kinds of categories whose colimits are well-behaved with respect to a type of limit, such as sifted categories.
This can be rephrased in more elementary terms by saying that:
Just as all finite colimits can be constructed from initial objects, binary coproducts, and coequalizers, so a cocone on any finite diagram can be constructed from these three.
In constructive mathematics, the elementary rephrasing above is equivalent to every Bishop-finite diagram admitting a cocone.
More generally, if is an infinite regular cardinal (or an arity class), then a -filtered category is one such that any diagram has a cocone where has arrows. The usual filtered categories are then the case. Note that a preorder is -filtered as a category just when it is -directed as a preorder.
Even more generally, if is a class of small categories, a category is called -filtered if -colimits commute with -limits in Set. When is the class of all -small categories for an infinite regular cardinal, then -filteredness is the same as -filteredness as defined above. See ABLR.
If is the class consisting of the terminal category and the empty category — which is to say, the class of -small categories when is the finite regular cardinal — then being -filtered in this sense is equivalent to being connected. Note that this is not what the explicit definition given above for infinite regular cardinals would specialize to by simply setting (that would be simply inhabitation).
Every category with a terminal object is filtered.
Every category which has finite colimits is filtered.
A product of filtered categories is filtered.

Keys are unique identifiers that you provide as a parameter when you perform any operation on data. The following applies to keys:
Keys are strings, typically enclosed by quotes for any given SDK.
No spaces are allowed in a key.
Separators and identifiers are allowed, such as underscore: 'person_93847'.
A key must be unique within a bucket; if you attempt to

Maximum key size is 250 bytes. Couchbase Server stores all keys in RAM and does not remove these keys to free up space in RAM. Take this into consideration when you select keys and key length for your application.
This last point about key size is important if you consider the size of keys stored for tens or hundreds of millions of records. One hundred million keys which are 70 Bytes each plus meta data at 150 Bytes each will require about 45 GB of RAM for document meta data.


text: Objectives: Children with severe cerebral palsy (CP) commonly have gastrointestinal (GI) dysfunction. Whey-based enteral formulas have been postulated to reduce gastroesophageal reflux (GOR) and accelerate gastric emptying (GE). The authors investigated whether whey-based (vs casein-based) enteral formulas reduce GOR and accelerate GE in children who have severe CP with a gastrostomy and fundoplication. Methods: Thirteen children received a casein-based formula for 1 week and either a 50% whey whole protein (50% WWP) or a 100% whey partially hydrolyzed protein (100% WPHP) formula for 1 week. Reflux episodes, gastric half-emptying time (GE t1/2), and reported pain and GI symptoms were measured. Results: Whey formulas emptied significantly faster than casein (median [interquartile range (IQR)] GE t1/2, 33.9 [25.3-166.2] min vs 56.6 [46-191] min; P =.033). Reflux parameters were unchanged. GI symptoms were lower in children who received 50% WWP (visual analog symptom score, median [IQR], 0 [0-11.8]) vs 100% WPHP (13.0 [2.5-24.8]) (P =.035). Conclusion: This pilot study shows that in children who have severe CP with a gastrostomy and fundoplication, GE of the whey-based enteral formula is significantly faster than casein. The acceleration in GE does not alter GOR frequency, and there appears to be no effect of whey vs casein in reducing acid, nonacid, and total reflux episodes. The results indicate that enteral formula selection may be particularly important for children with severe CP and delayed GE.

Here's the post from Wired.com
1888: The earliest known musical recording is made. The piece, Georg Friedrich Handel's Israel in Egypt, is recorded on a paraffin cylinder.
Israel in Egypt, assigned the catalog number HWV 54, is an oratorio, a form in which Handel excelled. Like his more famous Messiah, Israel in Egypt is composed using biblical passages, mainly from Exodus and the Psalms.
Unlike the Messiah, however, it didn't enjoy much of a reception when it premiered in 1739. As a result, Handel shortened the work and inserted a few Italian arias to lighten the mood a bit.
Nevertheless, it was selected by Col. George Gourand, Thomas Edison's foreign sales agent, for the first musical recording. Gourand made his recording in London's Crystal Palace, using Edison's yellow paraffin cylinder -- candle wax, essentially.

Let $G= SL(2, F)$, given a torus $T$, the Weyl group with respect to $T$ is defined to be $W=N(T)/Z(T)$, the quotient of the normalizer $N(T)$ of the torus by the centralizer $Z(T)$ of the torus.
My question might be basic and elementary for some of you, but I would like to be in a complete understanding.
Why Weyl group of $SL(2, F)$ is the group $\mathbb{Z}/2\mathbb{Z}$?

It's not made explicit here what field $F$ is given, though the tag p-adic-groups is suggestive. Usually "the" Weyl group is defined for an algebraic group over an arbitrary algebraically closed field, relative to any given maximal torus (all such tori being conjugate). It would help to know what kind of textbook source you are starting with, since the question is certainly "basic and elementary" once the context is clear. But more precision is needed if you start to look at fields of definition which are not algebraically closed. – Jim Humphreys May 6 '12 at 13:53
The field $F$ is non-Arch. local field and the tag for p-adic group because am dealing with $SL(2,F)$. – Dragon May 6 '12 at 15:52

Two people (so far) have tried to provide some sensible information, but I think the question itself is too loosely formulated to have a real answer. What you are looking at is the group of rational points of an algebraic group of rank 1 over a certain type of infinite field, which could be of characteristic 0 or not. This group itself is just an abstract group, which doesn't immediately have a definite "Weyl group" attached. It makes more sense to start with the algebraic group $G=\mathrm{SL}_2$, which is defined and split over any prime field. (The language of group schemes is appropriate here.) Over any field $F$, the group of rational points is just the usual group of $2 \times 2$ matrices of determinant 1 over $F$. It makes no difference for your question what $F$ is.
In $G$ there is a single well-defined (up to isomorphism) Weyl group $N_G(T)/T$ which just has order 2, as described concretely by Mrc Plm in the split case. All maximal tori of $G$ are conjugate as well as self-centralizing, so the choice doesn't matter.
However, if $F$ fails to be algebraically closed, the resulting abstract group $\mathrm{SL}_2(F)$ is more challenging because $G$ typically has more than one class of maximal tori defined over $F$. In your rank 1 case it's not so bad because there are just two possibilities, the "split" and "anisotropic" (or "compact") types of maximal tori. The structure of the normalizer modulo centralizer of each type has to be looked at case-by-case in terms of the "absolute" Weyl group. In higher ranks the situation gets more complicated. Anyway you have to take account of the variation of structure in the points of $G$ over an arbitrary field.
Again I'd emphasize that the basic theory coming from study of algebraic groups doesn't depend on which field of definition $F$ (even finite) you are ultimately interested in, though of course the end results about rational points depend heavily on that field. There are somewhat different expositions of all this in standard textbooks, but the idea is always the same in your limited situation.

Let $T$ be a split torus over a field $F$.
The Weyl group is by definition a subgroup of the group of outer morphisms (defined over $F$).
There are only two automorphism (the inverse and the identity) of $T$ (defined over F), so the group of outer automorphism is isomorphic to $\mathbb{Z}/2$.
Both can realized by the conugation via the non-trivial element $\begin{pmatrix} 0 & -1 \newline 1 & 0 \end{pmatrix}$ and by the identity elment respectively.
So the Weyl group has at least two elements, hence exactly two elements.
Similiar you can argue for the maximal split torus in $SL(n)$ or $GL(n)$.
For non-split tori, the question is more difficult to answer. I know only the $GL(n)$-situation. In $GL(2)$, the tori is isomorphic to a multiplicative group of a quadratic field extensions, and the outer automorphisms of the tori are isomorphic to the Galois group. Now these can be realized by conjugation of elements $GL(2)$, but they can not be realized by elements of determinant $1$.

For your last sentence, note that $O_2(\mathbb{R})$ does not embed in $SL_2(\mathbb{R})$. – S. Carnahan May 18 '12 at 8:19
Yes. I guess it is clear that every thing should be defined uniquely up to conjugation, and surely the determinant will be preserved, so I win my bet;) – Marc Palm May 18 '12 at 11:20
One can approach this from different point of views:
On a matrix level, the subgroup consisting of the diagonal matrices is an example of a torus $T$. Its centralizer is $T$ itself, and its normalizer $N(T)$ the group of monomial matrices in $G$. One then verifies that $N(T) / Z(T)$ is the cyclic group on two elements.
One can also use the projective line $\mathbb{P}^1(F)$. Then the centralizer is the subgroup fixing the 'apartment', which in this case is a pair of points of the projective line, pointwise. The normalizer is the subgroup of $G$ stabilizing this apartment. The Weyl group (the quotient) is then the group of faithful automorphisms of the apartment. So the Weyl group here consists of the identity and an involution switching the two points of the apartment.

Using the Invoke-PolicyEvaluation cmdlet
Invoke-PolicyEvaluation is a SQL Server cmdlet that reports whether a target set of SQL Server objects complies with the conditions specified in one or more Policy-Based Management policies.
Invoke-PolicyEvaluation evaluates one or more policies against a set of SQL Server objects called the target set. The set of target objects comes from a target server. Each policy defines conditions, which are the allowed states for the target objects. For example, the Trustworthy Database policy states that the TRUSTWORTHY database property must be set to OFF.
The -AdHocPolicyEvaluationMode parameter specifies the actions taken:
Check
Report the compliance status of the target objects using the credentials of your current login. Do no reconfigure any objects. This is the default setting.
CheckSqlScriptAsProxy
Report the compliance status of the target objects using the credentials of the ##MS_PolicyTSQLExecutionLogin## proxy login. Do no reconfigure any objects.
Configure
Report the compliance status of the target objects using the credentials of your current login. Reconfigure any settable and deterministic options that are not in compliance with the policies.
How you specify a policy depends on where the policy is stored. Policies can be stored in two formats:
 - They can be objects stored in a policy store, such as an instance of the Database Engine. You can use the SQLSERVER:\SQLPolicy folder to specify the location of policies in a policy store. You can use Windows PowerShell cmdlets to filter the input polices based on their properties, such as using Where-Object to filter on the policy category or Get-Item to filter on policy name.
 - They can be exported as XML files. You can use a file system drive, such as D:, to specify the location of the XML files. You can use Windows PowerShell cmdlets such as Where-Object to filter the policies on their file properties, such as file name.
If the policies are stored in a policy store, you must pass in a set of PSObjects pointing to the policies to be evaluated. This is typically done by piping the output of a cmdlet such as Get-Item to Invoke-PolicyEvaluation, and does not require that you specify the -Policy parameter. For example, if you have imported the Microsoft Best Practices policies into your instance of the database engine, this command evaluates the Database Status policy:
sl "SQLSERVER:\SQLPolicy\MyComputer\DEFAULT\Policies"
Get-Item "Database Status" | Invoke-PolicyEvaluation -TargetServerName "MYCOMPUTER"
This example shows using Where-Object to filter multiple policies from a policy store based on their PolicyCategory property. The objects from the piped output of Where-Object is consumed by Invoke-PolicyEvaluation.
sl "SQLSERVER:\SQLPolicy\MyComputer\DEFAULT\Policies"
gci | Where-Object {$_.PolicyCategory -eq "Microsoft Best Practices: Maintenance"} | Invoke-PolicyEvaluation -TargetServer "MYCOMPUTER"
If the policies are stored as XML files, you must use the -Policy parameter to supply both the path and name for each policy. If you do not specify a path in the -Policy parameter, Invoke-PolicyEvaulation uses the current setting of the sqlps path. For example, this command evaluates one of the Microsoft Best Practice policies installed with SQL Server against the default database for your login:
Invoke-PolicyEvaluation -Policy "C:\Program Files\Microsoft SQL Server\100\Tools\Policies\DatabaseEngine\1033\Database Status.xml" -TargetServerName "MYCOMPUTER"
This command does the same thing, only it uses the current sqlps path to establish the location of the policy XML file:
sl "C:\Program Files\Microsoft SQL Server\100\Tools\Policies\DatabaseEngine\1033"
Invoke-PolicyEvaluation -Policy "Database Status.xml" -TargetServerName "MYCOMPUTER"
This example shows using the Get-ChildItem cmdlet to retrieve multiple policy XML files and pipe the objects into Invoke-PolicyEvaluation:
sl "C:\Program Files\Microsoft SQL Server\100\Tools\Policies\DatabaseEngine\1033"
gci "Database Status.xml", "Trustworthy Database.xml" | Invoke-PolicyEvaluation -TargetServer "MYCOMPUTER"
Use three parameters to specify the set of target objects:
 - -TargetServerName specifies the instance of SQL Server containing the target objects. You can specify the information in a string that uses the format defined for the ConnectionString property of the SQLConnection class. You can use the SqlConnectionStringBuilder class to build a correctly formatted connection string. You can also create a SqlStoreConnection object and pass it to -TargetServer. If you supply a string that has only the name of the server, Invoke-PolicyEvaluation uses Windows Authentication to connect to the server.
 - -TargetObjects takes an object or array of objects that represent the SQL Server objects in the target set. For example, you could create an array of Database class objects to pass in to -TargetObjects.
 - -TargetExpressions takes a string containing a query expression that specifies the objects in the target set. The query expression is in the form of nodes separated by the '/' character. Each node is in the form ObjectType[Filter]. Object type is one of the objects in a SQL Server Management Object (SMO) object hieararchy. Filter is an expression that filters for objects at that node. For more information, see Query Expressions and Unique Resource Names.
Specify either -TargetObjects or -TargetExpression, not both.
This example uses an Sfc.SqlStoreConnection object to specify the target server:
sl "C:\Program Files\Microsoft SQL Server\100\Tools\Policies\DatabaseEngine\1033"
$conn = New-Object Microsoft.SqlServer.Management.Sdk.Sfc.SqlStoreConnection("server='MYCOMPUTER';Trusted_Connection=True")
Invoke-PolicyEvaluation -Policy "Database Status.xml" -TargetServerName $conn
This example uses -TargetExpression to identify the specific database to evaluate:
sl "C:\Program Files\Microsoft SQL Server\100\Tools\Policies\DatabaseEngine\1033"
Invoke-PolicyEvaluation -Policy "Database Status.xml" -TargetServerName "MyComputer" -TargetExpression "Server[@Name='MYCOMPUTER']/Database[@Name='AdventureWorks2008R2']"
To evaluate policies against an instance of Analysis Services, you must load and register an assembly into sqlps., create a variable with an Analysis Services connection object, and pass the variable to the -TargetObject parameter. This example shows evaluating the Best Practices surface area configuration policy for Analysis Services:
sl "C:\Program Files\Microsoft SQL Server\100\Tools\Policies\AnalysisServices\1033"
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices")
$SSASsvr = new-object Microsoft.AnalysisServices.Server
$SSASsvr.Connect("Data Source=Localhost")
Invoke-PolicyEvaluation -Policy "Surface Area Configuration for Analysis Services Features.xml" -TargetObject $SSASsvr
To evaluate Reporting Services policies, you must load and register an assembly into sqlps., create a variable with a Reporting Services connection object, and pass the variable to the -TargetObject parameter. This example shows evaluating the Best Practices surface area configuration policy for Reporting Services:
sl "C:\Program Files\Microsoft SQL Server\100\Tools\Policies\ReportingServices\1033"
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Dmf.Adapters")
$SSRSsvr = new-object Microsoft.SqlServer.Management.Adapters.RSContainer('MyComputer')
Invoke-PolicyEvaluation -Policy "Surface Area Configuration for Reporting Services 2008 Features.xml" -TargetObject $SSRSsvr
By default, the output of Invoke-PolicyEvaluation is displayed in the command prompt window as a concise report in human-readable format. You can use the -OutputXML parameter to specify that the cmdlet instead produce a detailed report as an XML file. Invoke-PolicyEvaluation uses the Systems Modeling Language Interchange Format (SML-IF) schema so the file can be read by SML-IF readers.
sl "SQLSERVER:\SQLPolicy\MyComputer\DEFAULT\Policies"
Invoke-PolicyEvaluation -Policy "Datbase Status" -TargetServer


Memory Box Shows Photos Based On Fingerprint
Memory Box Shows Photos Based On Fingerprint
With his young son's birthday coming up in a few weeks, [Mike Buss] wanted to build him something fun that the boy could hold on to all his life. After doing some sketching, [Mike] arrived at the idea to make a memory box uses a fingerprint scanner to show different pictures based on the fingerprint.
[Mike] started by rendering the box in Blender and then cutting a sizeable hole in the lid for the E-ink screen. That's around the time the first problem came up — there were weird vertical lines in the display. Sure enough, that screen was broken. Then he added the SD card reader, but the SD card wouldn't work, and was heating up besides. Finally, the fingerprint scanner was causing issues, but it turned out that the power supply was at fault.
After all of that, [Mike] switched from an ESP32to a Raspi Zero W to simplify the whole process of finding a photo tagged with the person's fingerprint. [Mike] added a Python script that listens for new memories over Wi-Fi. A memory in this case consists of a picture, a description, a list of people tagged in the picture, and some additional metadata.
One important lesson [Mike] learned was that of balancing planning vs. just taking action. If he had taken the time to consider the complexity of the tagged-photo retrieval system, he would have arrived at an SBC solution much sooner. Be sure to check out the build video after the break.
You can have all sorts of fun with fingerprint scanners, like memory shows photos based fingerprint

User Guide
Setting Up Amazon Macie
Step 1 - Enable Macie
When you sign up for AWS, your AWS account is automatically signed up for all services in AWS, including Amazon Macie. If you don't have an account, use the following procedure to create one.
To sign up for AWS
 1. Open _URL_ and then choose Create an AWS Account.
 Note
 This might be unavailable in your browser if you previously signed into the AWS Management Console. In that case, choose Sign in to a different account, and then choose Create a new AWS account.
 2. Follow the online instructions.
 Part of the sign-up procedure involves receiving a phone call and entering a PIN using the phone keypad.
When you launch the Macie console for the first time, choose Get Started and complete the following procedure to enable Macie.
Important
The AWS account that you use to enable Macie is automatically designated as your master account. For more information, see Concepts and Terminology.
To enable Amazon Macie
On the Enable Amazon Macie page, complete the following steps:
 1. Verify region preferences by reviewing the value in the drop-down menu under the Region section.
 Note
 The region that you are currently signed in to is automatically selected.
 2. Required: create the Identity Access Management (IAM) roles that provide Macie with access to your AWS account. You can create these roles and the required policies by launching the AWS CloudFormation stack templates found at the URLs listed below. These roles only need to be created once for use in all regions. For more information about AWS CloudFormation and CloudFormation stacks, see What is AWS CloudFormation? and Working with Stacks.
 3. Required: make sure that AWS CloudTrail is enabled in your account. If CloudTrail is not enabled, you must navigate to the AWS CloudTrail console and enable AWS CloudTrail. For more information, see Overview for Creating a Trail.
 4. Grant Macie the required permissions to access your CloudTrail data by checking the checkbox in the Permissions section.
 5. Choose Enable Macie.
Step 2 - Integrate Amazon S3 with Macie
To classify and protect your data, Macie analyzes and processes information from AWS CloudTrail and Amazon S3. Enabling CloudTrail in your account is required in order to enable Macie. Integrating S3 with Macie (in other words, initially specifying one or more S3 buckets for Macie to monitor) is not required in order to enable Macie. However we strongly recommend that you integrate with S3 as part of setting up Macie and specify at least one S3 bucket that contains objects that you want Macie to classify and monitor. For more information and details about how Macie classifies your data, see Classify Your Data with Macie.
When you integrate with S3, Macie creates a trail and a bucket to store the logs about the S3 object-level API activity (data events) that it will now analyze along with other CloudTrail logs that it processes.
Important
Macie has a default limit on the amount of data that it can classify in an AWS account. Once this data limit is reached, Macie stops classifying the data in this AWS account. The default data classification limit is 3TB. You can contact customer support and request an increase to the default limit.
You can use the following procedure to integrate with S3 as part of setting up Macie:
 1. Log in to AWS with the credentials of the AWS account that is serving as your Macie master account.
 2. Navigate to the Macie console's Integrations tab and choose the Services tab.
 3. In the Services tab, select the account id (master or member) in the Select an account drop-down. The Amazon S3 tile is then displayed.
 4. Choose the Add button in the Amazon S3 tile.
 5. On the Selected S3 buckets and prefixes page, choose the edit icon, and then select either the full buckets (recommended) or bucket/prefix combinations for Macie to monitor. You can select up to 250 S3 buckets and prefixes.
 Note
 You can only select S3 buckets in your current AWS region.
 Important
 When you specify an S3 bucket, by default, Macie only classifies objects that are added to the bucket after your bucket selection is complete. However you can instruct Macie to classify all existing objects in the specified S3 bucket by checking the Classify all checkbox.
 If you decide to Classify all S3 objects in a bucket, make sure to note the following values:
 - Total size - total size of the data within this bucket, which is the sum of the sizes of all the objects in the bucket. This value is displayed in the Total size column on the Select S3 buckets for Macie to monitor page.
 - Total processed - total size of the data from the bucket that Macie will actually classify. This value is displayed in the Total processed column on the Select S3 buckets for Macie to monitor page.
 - Total cost estimate - the total content classification cost estimate for each S3 bucket. This value is displayed in the Total cost estimate column on the Select S3 buckets for Macie to monitor page.
 These values are greyed out if Classify all checkbox is not checked. These values are calculated based on the snapshot of the contents of your S3 buckets taken within the last 48 hours.
 The Total cost estimate for each bucket is based on the Total processed value for that bucket and the general Macie pricing of $5 per GB processed by the content classification engine. The total cost estimates are provided only for S3 buckets, not for prefixes. For more information, see Amazon Macie Pricing.
 The Total processed value for each bucket is calculated as follows:
 - If an object's size is less than 1KB, 1KB is added to the Total processed value. Otherwise, the object's actual size is added to the Total processed value.
 - If the object's size is greater than 20MB, 20MB is added to the Total processed value. Otherwise, the object's actual size is added to the Total processed value.
 - For object in Amazon Glacier vaults, 0 is added to the Total processed value.
 Note that it is possible for the Total processed value of an S3 bucket to be higher than the Total size value.
 6. When you've finished your selections, choose Review and Save. And when you've finished reviewing your selections, choose Save.

In 2001, the Global Pertussis Initiative was established as a scientific forum to analyze the status of pertussis globally and to evaluate various immunization strategies to improve disease control. Thirty-seven multidisciplinary experts from 17 countries participated.
The initiative was conducted in 3 stages: assessment of the international epidemiology, diagnosis, health and economic burden, and prevention and treatment of pertussis; evaluation and prioritization of 7 immunization strategies to address the problems; and identification of solutions to surmount potential barriers to the implementation of these strategies. A health-economic model, created for the Initiative, analyzed the cost-effectiveness of the selected immunization strategies. Discussion, debate, and consensus were facilitated via a roundtable meeting, teleconferences and use of a closed, interactive website, allowing the participants to share data, knowledge, experience, and opinion. This article describes the processes undertaken to conduct the Initiative.
