Let G be a fuzzy graph. A family of fuzzy sets on a set V is called k-fuzzy coloring of if i) ii) iii) for every strong edge (that is ., ) of G, . The minimum number of k for which there exists a k-fuzzy coloring is called fuzzy chromatic number of G and is denoted by . Then is the partition of independent sets of vertices of G in which each sets has the same color is called the fuzzy chromatic partition. A fuzzy dominator coloring of a fuzzy graph G is a proper fuzzy coloring of G in which every vertex of G dominates every vertex of at least one color class. The minimum number of colors required for a fuzzy dominator coloring of G is called the fuzzy dominator chromatic number (FDCN) and is denoted by . In this chapter , we introduce a new class of color partition and their related concepts. Also, we extensively studied the concept of chromatic polynomial for irregular fuzzy coloring and fuzzy neighborhood distinguished coloring.
Palabras Clave: aprendizaje significativo, metrologÃa, pie de rey, sistema de unidades The aim of this study is to promote the application of active methodologies for teaching and learning the use of the Vernier Calibrator or Slide Gauge with the metric system (0.05 and 0.02 mm) and the English system (1/128 and 0.001). Inches) of units by means of the expansion of the scales of graduation, both of the main scale and that of the Vernier, using a sheet (card) in A4 format, ruler, grader and pencils. An introduction was made on Metrology, measurement systems and units of measurement, as well as the measurement instrument, also a proposal was made to obtain the assessment or resolution of the measurement instrument. In order to achieve the validity of this study, and to obtain a meaningful and lasting learning, active learning methodologies were used such as: cooperative work, problem-based learning and project-based learning, methodologies that allow the student to participate actively and be motivated in his training process as a future engineer through his/her proper planning of playful activities in classes, guided by the teacher, with meaningful materials and conceptually easy to understand. To finalize the study, an application project was developed, which consists of the development of a Vernier wood calibrator with their respective graduations.

Sarah Schwartz graduated from Indiana University Southeast in 2014 with a bachelor’s degree in education and a concentration in math. There weren’t many positions available for math teachers near her home in southern Indiana, so she continued to work part-time in the IU Southeast math lab. She also got a second job at a Goodwill retail store to earn extra income.
Shortly after, she was diagnosed with muscular dystrophy (MD), a disease that causes progressive weakness and degeneration of the skeletal muscles, making it difficult to do things like walking, climbing stairs and sitting and standing. However, Sarah didn’t let her disability stop her from pursuing her passion.
“When I learned that Goodwill was opening an Excel Center in Clarksville, I told one of my co-workers that I was going to be one of the math teachers,” Sarah said. “Not only am I now one of the math teachers, but I also ended up being the first teacher hired at the school.”
The Excel Center is a tuition-free high school for adults that helps students remove barriers to completing their diploma. Ms. Sarah, as her students call her, has had a huge impact on those around her.
“I struggled with math growing up, but Ms. Sarah helped me understand things in a clear way, which helped me build confidence and the belief that I can learn,” said Ashley Neal, one of Sarah’s students at The Excel Center.
Sarah’s position at The Excel Center has provided her with a means to serve by doing what she loves and also allows her to live independently. In addition, she is currently working to complete her master’s degree in math education to help with The Excel Center’s dual credit program.
“Muscular dystrophy doesn’t define me and won’t keep me from doing the things I want to do,” Sarah said.

Sometimes the thrill of mathematics doesn’t come from the question, but from a beautiful solution. Consider the approach EMU math professor Owen Byer took when deciding which problems to include in the new textbook he co-authored with math-professor-turned-vice president and academic dean Deirdre Longacher Smeltzer, and Regent University professor Kenneth Wantz:
“In my own view,” he said, “either it should be a really interesting question, or – lacking that – the solution should be beautiful. Even average problems are worth including if the solution teaches you something.”
This November marked the publication of the long-anticipated – and, already, long-used – textbook Journey into Discrete Mathematics (Mathematical Association of America Press, 2018).
“This is definitely the best math textbook that I’ve ever used,” said sophomore Andrew Nord after a recent session of his discrete math class, which is the latest to use the – until now, pre-published – book. “It explains the concepts very fully and in a way that can be understood fairly easily.”
From the start
Byer, Smeltzer and Byer’s University of Delaware PhD advisor Felix Lazebnik began talking about writing Journey at about the same time the trio’s earlier textbook Methods for Euclidean Geometry(MAA, 2010) was published. All three had doctoral training in discrete math and had taught it many times, and “it seemed like a good second joint project,” Smeltzer said.
A year into the writing of Journey, however, Lazebnik needed to bow out – but generously granted permission for materials that he had developed to remain in the textbook. Byer and Smeltzer then invited Wantz, a former grad school colleague of Byer’s, to join them, and the new trio continued even as a new wrinkle developed: Smeltzer’s transition to being undergraduate dean left her little time to focus on the textbook. While each author ultimately made similar contributions, she said, Byer provided leadership and did “more of everything, especially generating problems and solutions.”
Once drafted, Journey entered what Byer modestly dubbed “a long process” of revising and polishing. For Smeltzer, that process posed the biggest challenge of writing Journey, second only to her limited time: “It’s hard to see something with fresh eyes when you’ve been working on it for a long time.”
There was a beautiful way to help with that problem, however.
A beautiful solution: students
As early as half a decade ago, Byer and his colleagues at EMU began using Journey in the classroom, first in pdf form and later – including this fall, even as the book was heading to press – in three-ring binders in Professor Daniel Showalter’s discrete math class.
“This is definitely the best math textbook that I’ve ever used. It explains the concepts very fully and in a way that can be understood fairly easily.” –Andrew NordDoing that had distinct benefits: Students could learn from a textbook grounded in experienced educational practice. Plus, students’ fresh eyes would help tease out what needed better explanation – and they’d find mistakes, discoveries that were often rewarded with bonus points.
Another of Showalter’s students, sophomore Silas Clymer, remembers – with a note of satisfied glee in his voice – finding a misleading hint in a homework problem. But more importantly, “It’s definitely cool having the writer of the book downstairs in an office,” he said. “You can go to talk to him if you need to.”
Showalter often teaches using a flipped classroom model, a model that depends on having a clearly written textbook: students learn concepts on their own from the textbook, and show up to class for answers to their questions and content-related activities. Even prepublicaton, he said, the evolved Journey proved an effective flipped-classroom text.
“It’s very clear,” Showalter said. “It’s rigorous and precise, and has plenty of examples.”
His students agree.
“I’ve never really learned from a textbook before,” said first-year student Jeremiah Yoder after a recent class period during which Showalter guided students in applying newly learned concepts to solve a variety of famous problems. “The textbook was always supplementary. But with this textbook, I feel like I’m on course without assistance, so I’m learning well.”
“We really don’t need a teacher,” his classmate Isaac Andreas joked. “That’s why we can just play math games in class every day. I mean, we spend a little bit of time on the content during class, but then we go off and [solve fun problems]. It’s still math.”
‘Exquisite and engaging’
Byer expects Journey to be adopted more widely than the “niche” Methods, as discrete math is taken not only by math majors but also students in computer science, and since MAA Press is now an imprint of the American Mathematical Society.
The publisher describes the text’s exposition as “exquisite and engaging,” with “detailed descriptions of the thought processes that one might follow to attack the problems of mathematics. The problems are appealing and vary widely in depth and difficulty.”
That’s no surprise, of course, taking into account the authors’ cumulative expertise from decades of teaching – and loving the beauty of – math.

Homemade Detergent, revisited
About a month ago, I calculated that homemade detergent didn't really save money versus buying value detergent on sale. However, I have had to revisit my calculations; in actuality I've been using half as much detergent for each load as I had anticipated. So each load actually costs me about $0.035 per load. I haven't tried using half as much value detergent; I don't know whether it would work as well or not. But it's the fastest way I can think of to save money on detergent - use half as much as you usually do, and see if you notice a difference.

Kinder students practiced more than, less than, and equal to using natural objects.
Students also developed a garden character using these concrete manipulatives.
A simple leaf helped introduce and engage 1st graders into fractional thinking.
Students demonstrated their understanding of the concept using sidewalk chalk and trash collected from around the garden.
In 45 minutes most of the students left the outdoor classroom with a REAL experience of how to make fractions using their hands and their heart, not just their head.


When a child is having difficulty in any mathematics subject area, it is important to discover ways to help. Probability, Statistics and Calculus are areas in which even high achievers may find themselves struggling.
Classroom instruction is great for many, but for others students, a 45-minute class and surrounded by the distractions of their classmates, is simply not the ideal way to learn. If students pay at their desks they could not be able to attend to a portion of the lesson for many reasons. And since math works like it is a chain with one concept leading to the next one, a “missed link” causes subsequent content to cease to make sense.
Probability & Statistics
Many students are struggling when it comes to Probability and Statistics because of no cause or fault of their own. For all that, Probability and Statistics has its own unique terminology and rules. However, the stress experienced by Probability and Statistics students can result in a loss self-confidence.
If the student is struggling with Probability and Statistics, look pay someone to do statistic homework for a thorough, step-by-step Probability and Statistics tutorial, one that simplifies difficult notions by breaking them up into smaller pieces, using illustrations and providing real-life examples.
Need assistance with your calculus? You are not alone! Calculus is among the most difficult subjects for many students even students who are typically high achievers. But here’s some good news when a student is acquainted with the particular “language” of calculus, it will become one of the most simple, and even most enjoyable, things for them to do!
Calculus is based on a special type of logic. Once it’s established inside students’ brains it is simple to apply to any type of problem. The problem is that some students learn best at different speeds, and in different contexts, than other.
A lot of students struggle with geometry. Geometric shapes can’t be translated well on a blackboard. Students require a more visual imagination to understand concepts such as: lines and points; angles and parallel lines; analytic geometry that includes the coordinate plane midpoints; distance; slope and equations of lines formal proofs and deduction; polygons and triangles; an introduction to triangles; angles of triangles; right triangles pythagorean theorem; congruent triangles; similar triangular; quadrilaterals: trapezoids, parallelograms as well as rectangles, rhombuses and squares; perimeters and areascircles which are lines that connect with circles: radius, diameter, chord and tangent. Secant is the equation of a circle angles related to a circle as well as the circumference and area! Nonetheless geometry is an important part of a well-rounded education.
The tutoring programs and tutorials offered by tutors can aid students in understanding difficult math concepts and perform better in their math class. Locate a tutor in math that will provide a complete tutorial program and cement challenging math concepts with repetition. Hundreds of interactive exercises are provided by tutors to make sure that students master all the formulas and concepts covered in the review. Tutors can also assist with recommending and providing useful math worksheets. Such workbooks provide additional practice and exercises and students may eventually learn to tackle problems on their own.
The experience and the sense of accomplishment that a tutoring program will bring to the student will bring great benefits for many years to come. Not only will it assist students to achieve a top grade at school in Probability and Statistics or Calculus, but it will provide a solid base for success in the future and help with college entrance exams.


Multiple time series forecasting
0) ARIMA(p,d,q) forecasting equation: ARIMA models are, in theory, the most general class of models for forecasting a time series which can be made to be “stationary” by differencing (if necessary), perhaps in conjunction with nonlinear transformations such as logging or deflating (if necessary). Nov 27, 2020 · Just to complement the available answer, a recent trend in time series forecasting is what is called Global forecasting. This is why simultaneously modeling multiple time series plays a critical role in many fields. Run the following commands to Aug 17, 2021 · Training Models on Multiple Time Series. (2011). Jun 01, 2010 · The topic of his research is Multiple-Output Modeling for Multi-Step-Ahead Time Series Forecasting. Forecasting time series with complex seasonal patterns using exponential smoothing. Regime shifts refer to the changing behaviors exhibited by series at different time intervals. I have tried the following code: d1 <- ts(d, start=2000, end=2009) However, this code consider the time-series as one long time-series for 100 years I think. It is the seventh in a series of examples on time series regression, following the presentation in previous examples. The choice of these series is typically guided by both empirical experience and by economic theory, for example, the theory of the term structure of interest rates suggests that the spread between long and short term interest Introduction to Time Series Regression and Forecasting (SW Chapter 14) Time series data are data collected on the same observational unit at multiple time periods Aggregate consumption and GDP for a country (for example, 20 years of quarterly observations = 80 observations) Yen/$, pound/$ and Euro/$ exchange rates (daily data for Forecasting multiple time series.

I recently needed to sum all the negative and positive numbers in a range before adding them together. This was to see the total earnings and the total expenses, instead of only having the sum of the two. The problem was that they were all mixed up in a long list, so I could not easily do two simple SUM statements. What I ended up with was using the SUMIF function using two formulas:
One for negative numbers:
and one for positive numbers:
Depending on your locale you may have to change the comma (,) to a semicolon (;).
The above is quite self explanatory, SUMIF takes a range and a condition on when cells should be part of the summation. For the first one (negative) it has to be below zero and for the second one (positive) it has to be above zero. This can give you the following result when you make the two summations using the above:
I hope this helps you to do your summations, I found this way harder to figure out than it should be :)


[Brief illustration] – Single Particle Tracking (SPT) is a powerful class of tools for acquiring information about the dynamics of biological macromolecules moving inside living cells. In this work, we are interested in comparing algorithms with respect to the performance of localization and motion model estimation at very low signal levels. A standard approach for estimation is to use Gaussian Fitting (GF) to determine the position of an emitter in an image, followed by linking to produce a trajectory. These trajectories are then analyzed by using Mean Square Displacement (MSD) or Maximum Likelihood (ML) to estimate motion parameters, such as diffusion coefficients. However, both MSD and the standard formulation of ML assume a linear measurement model with simple additive Gaussian noise, which begins to fail as image intensity decreases. We have introduced two nonlinear methods that more accurately model camera-based measurements: Sequential Monte Carlo combined with Expectation Maximization (SMC-EM), and Unscented Kalman Filter combined with Expectation Maximization (U-EM).

A cube is a special cuboid and belongs to the four-sided prisms with edges at right angles to each other. A cube has six congruent squares as boundary surfaces, which are parallel to each other in pairs.
In a cube, all twelve diagonals of the surface and all four diagonals of the space are of equal length - https://domyhomework.club/math-homework/ . To calculate the surface area s and the volume s, it is sufficient, for example, to specify the length of the body edge of the cube.
A cube-shaped box made of wood has an edge length of 80 cm - https://domyhomework.club/statistic-homework/ . How many square metres of wood are needed to make a box and what is its volume?
Wanted: AO in m^2; V in m^3
Given: a = 80 cm = 0.8 m
Answer: 3.8 m^2 of wood are needed at least for one crate. The crate has a volume of approx. 0.5 m^3.
The images in a vertical parallel projection are called normal images. The plan and elevation of a body are special normal images. Usually a special position of the body is chosen in which as many boundary surfaces as possible are parallel to one of the image planes. Since many edges are then perpendicular to an image plane and are therefore depicted as points, the images are often not very descriptive. For example, the elevation and ground plan of a cube are each a square.


Class 1 : An application to the natural Healing Frequencies, Fibonacci Spiral and Platonic Solids.
Introduction of Sacred Geometry, an application to numbers, sound, our body and Earth :
- What is it and why should it be included in elementary school ?
- A voyage to explore the symbolism and meaning of the numbers from 1 to 10 with 12 included.
- Introduction of Healing Frequencies such as 432 Hz, Solfeggio Frequencies through Vortex Mathematics.
- Introduction to the Ley Lines, Energetic Meridian of Earth.
In this lesson, you will learn :
- Learn to build Platonic Solids out of paper
- Learn the symbolism of the numbers from 1 to 10, and the number 12.
- Learn to draw geometrically the golden ratio observed in nature, including the Body.
- Learn to draw the Fibonacci Spiral
- Learn to draw the Flower of Life
- Learn to relate the Healing frequencies through sacred geometry and the sequence of Fibonacci's numbers.
We will be looking at the five famous Platonic Solids. As a practical activity, this lesson takes us to experience them through Origami.
Sacred Geometry is the blueprint of the natural world and the basis of all form.
It is an ancient science that explores and explains the energy patterns that create and unify all things and reveals the precise way that the energy of the Universe organizes itself.
On every scale, every natural pattern of growth or movement conforms inevitably to one or more geometric shapes.
The repetitive patterns of the Platonic solids that fit into each other are fractals. A fractal is a repetitive pattern that can be scaled to any size. The scale may change but the ratio is held constant.
Now the fractal patterns that shape the atom, according to Daniel Winter also shape our planets and stars, in fact the universe.
A fractal has self-similarity at all scales, it’s the same geometric pattern repeated. The inner structure in a fractal is reflected in the outer structure.
Fractal means fraction of the all, indicating that each piece is part of the
whole. It is the basic idea of a hologram and this is why according to Daniel Winter the universe at large is just a super-hologram. The fractals of electromagnetic energy interconnect everything with everything within the universe and are the basic building blocks of this hologram.
The fractal repetitive structures of electromagnetic energy weave a giant cobweb throughout the universe.
The wavelengths of planets and stars are huge in comparison with the
wavelengths of the atom, however when their wavelengths fit into the Fibonacci sequence of the Golden Mean, they interfere non-destructively; they implode and form a fractal attractor that we call gravity! This is how the planets and stars are connected by means of imploding electromagnetic waves that we experience as gravity.
So if the universe is in essence a hologram and there is only one principle that shapes everything from atoms to planets, stars, and the universe at large, we should find proof of these vortexes, Platonic Solids, and doughnut structures in all parts of the universe.

The Role of Statistics in Sports Predictions
In the world of sports, predictions play a significant role in determining outcomes. Fans, analysts, and bettors alike are constantly trying to forecast the results of games, matches, and tournaments. One key tool that has revolutionized the prediction game is the use of statistics. With the advent of advanced analytics and data tracking, the ability to analyze and interpret statistics has become essential for accurate sports predictions.
Statistics provide a wealth of information that can be used to understand the strengths and weaknesses of teams, players, and even specific game situations. By examining historical data, trends, and performance metrics, analysts can identify patterns and make informed predictions about future outcomes. From identifying player matchups to assessing team performance in different playing conditions, statistics provide valuable insights that can help bettors and enthusiasts make well-informed decisions.
Types of Statistics Used in Sports Predictions
When it comes to sports predictions, there are various types of statistics that can be used to gain a competitive edge. Some popular statistical categories include:
Challenges and Limitations of Statistical Analysis
While statistics offer valuable insights, it is important to recognize their limitations. It is essential to understand that statistics alone cannot guarantee accurate predictions, as there are several factors that can influence the outcome of a game.
One challenge of statistical analysis is the unpredictable nature of sports. Unexpected injuries, referee decisions, weather conditions, or even the “underdog effect” can significantly impact the result of a game, even if the statistics suggest otherwise.
Another limitation is the interpretation of statistics. Different analysts may focus on different metrics or give them varying degrees of importance. This subjectivity can lead to conflicting predictions based on the same set of statistics.
Furthermore, statistics are always based on past performance, and there is no guarantee that historical trends will continue in the future. The introduction of new players, coaching changes, or alterations in game strategies can render past statistics less relevant.
Using Statistics Wisely for Sports Predictions
To make the most of statistical analysis, it is crucial to use statistics as a tool rather than solely relying on them for predictions. Here are some tips on how to use statistics wisely:
In the world of sports predictions, statistics play a pivotal role in providing valuable insights and helping enthusiasts make more informed decisions. However, it is essential to recognize the limitations of statistical analysis and use it as a tool rather than the sole determinant of predictions. By combining statistics with other factors and staying updated with the latest information, sports enthusiasts can enhance their prediction accuracy and maximize their enjoyment of the game.

Pay attention to the call of the question. Ok, how about the natural log of a negative number. Consequently, don't spend time making it look pretty.
Often, there is a note or caption which explains it. It is a very useful skill that will come in handy later in the year. Recall that the slope-intercept form of a line is: If your professor has constructed an issue-laden exam, then it's critical to break the hypothetical into its component parts and organize the essay around the most important issues.
Here, the coefficient of the x-term is a positive integers and all other values are integers, so we are done. Suppose we want 30x growth: First, we have to write the equation of a line using the given information. Raychaudhuri was also Das's teacher when he was an undergraduate student of that institution in the '90s.
Transforming the slope-intercept form into general form gives If the problem in Example 4 had asked you to write the equation of a line perpendicular to the one given, you would begin the problem the same way. Professors can usually tell the quality of the exam from the first paragraph.
In addition to the equation of time, one also has to apply corrections due to one's distance from the local time zone meridian and summer timeif any. You can use either of the two points you have been given and you equation will still come out the same. If you need help calculating slope, click here for lessons on slope.
Of course, you need to rank the issues according to importance. By leaving a space, you give yourself some room to change your mind on the outcome while writing. Find the equation of a line that passes through the point 5, 5 and is parallel to What is your answer.

Number 3 – Traffic Light Craft
“Number rules the universe”.
Number Recognition is the first step in Nursery. Number recognition plays a vital role in almost all walks of one’s life. The child is supported in learning numbers with how to count.Number recognition skill is the term collectively used for the ability to recognize, visualize as well as name the very basic numerals – the numbers. These skills are strong support in supplementing the learning of mathematics concepts.
Number recognition and related skills have vital roles to play in almost all walks of one’s life. The number recognition skills build upon the initially developing number sense in a child, i.e., a child takes notice of the number of objects in a group. Additionally, these skills are strong support in supplementing the learning of arithmetic concepts.These skills impact the linguistic skills too.
On September 9, 2021, students of Grade Nursery were introduced to number 3 through real objects. Students understood the concept of number 3 by counting and showing objects related to the same. They learnt faster with their real life experiences.
Hands on activities are filled with full of fun and creativity. It allows students to directly observe and understand what is happening. It is very good at providing a foundation for knowledge and understanding. So to provide our students of Grade Nursery an experience, a traffic light craft related to number 3 was planned, where they pasted three different coloured circle cutouts on a black sheet. Students understood the concept of number 3 by counting those three lights in their craft and enjoyed it thoroughly.
Craft encourages children to play and experiment. It enhances student's eye-hand co-ordination and builds levels of manual dexterity. Such activities boost their self-esteem and develop their kinesthetic and cognitive skills.
