N byte error detecting and correcting code using reed-solomon and cellular au...eSAT Journals
Abstract
Single and double byte errors are most common errors in memory systems. With the advancement of technologies, more information
bytes can be send over a transmission channel, but this increases the probability of more errors. Here we propose a methodology for
detecting and correcting N-byte errors in the information bytes based on cellular automata (CA) concept. Cellular automata already
accepted as an attractive structure for error detecting and correcting codes. In this paper, highly efficient, reliable and less complex
cellular automata based N-byte error correcting encoder and decoder has been proposed. The design is capable of adding 2N check
bytes corresponding to N information bytes at the encoder, which are used at the decoder section to detect and correct the byte errors.
Keywords— Cellular Automata (CA), Reed-Solomon (RS) code, Information Bytes (IB), Check Bytes (CB)

Modeling and Simulation of an Active Disturbance Rejection Controller Based o...IJRES Journal
Based on studying active disturbance rejection control technology, a user defined Active Disturbance Rejection Controller (ADRC) block library was established in MATLAB / SIMULINK, by the way of developing M-function files for special nonlinear function and the subsystem packaging technology of building system modules for Tracking Differentiator(TD), Extended State Observer(ESO) and Non Linear State Error Feedback(NLSEF). The simulation example shows that the ADRC simulation model can be built in graphic modeling method, and the block parameters are easy to modify by using the defined ADRC module. Furthermore, the way to create new ADRC block library is simple and the library is easy to extend. Meanwhile it is a useful tool for searching and simulation of active disturbance rejection control technology.
This paper presents a design and implementation of FPGA based Bose, Chaudhuri and Hocquenghem (BCH) codes for wireless communication applications. The codes are written in VHDL (Very High Speed Hardware Description Language). Here BCH decoder (15, 5, and 3) is implemented and discussed. And decoder uses serial input and serial output architecture. BCH code forms a large class of powerful random error correcting cyclic codes. BCH operates over algebraic structure called finite fields and they are binary multiple error correcting codes. BCH decoder is implemented by syndrome calculation circuit, the BMA (Berlekamp-Massey algorithm) and Chien search circuit. The codecs are implemented over cyclone FPGA device.

This paper study the model reduction procedures used for the reduction of large-scale dynamic models into a smaller one through some sort of differential and algebraic equations. A confirmed relevance between these two models exists, and it shows same characteristics under study. These reduction procedures are generally utilized for mitigating computational complexity, facilitating system analysis, and thence reducing time and costs. This paper comes out with a study showing the impact of the consolidation between the Bacterial-Foraging (BF) and Modified particle swarm optimization (MPSO) for the reduced order model (ROM). The proposed hybrid algorithm (BF-MPSO) is comprehensively compared with the BF and MPSO algorithms; a comparison is also made with selected existing techniques.

APPLICATION OF PARTICLE SWARM OPTIMIZATION TO MICROWAVE TAPERED MICROSTRIP LINEScseij
Application of metaheuristic algorithms has been of continued interest in the field of electrical engineering because of their powerful features. In this work special design is done for a tapered transmission line used for matching an arbitrary real load to a 50Ω line. The problem at hand is to match this arbitray load to 50 Ω line using three section tapered transmission line with impedances in decreasing order from the load. So the problem becomes optimizing an equation with three unknowns with various conditions. The optimized values are obtained using Particle Swarm Optimization. It can easily be shown that PSO is very strong in solving this kind of multiobjective optimization problems.

Below I have written the answer but I need someone to please help me write it in APA format. Running head "Kenny's leadership: A further analysis"
1. Kenny is straightforward with the one he supervises. He is open to telling them what he feels and the important guiding points. He welcomes the complaints and gripes making the supervisors feel that they can express anything they want within the team. His team effectively speaks and communicated the information he wants. His team can feel at ease with him and he does not micromanage them. He lets them know that he is available if anything goes wrong. He also assures the employees that they would never get involved in anything that is not good for the growth of the company or to their career.
2. I on’t think all supervisors can operate in the similar fashion and can be effective. The success of Kenny is linked to the personality of Kenny and work ethic. All the supervisors cannot treat the team the way Kenny treats them. There are lot of bosses who do not have the same attitude like Kenny who has respect and hardworking for the employees. Most of the supervisors have a sense of dominating behavior. The mindset ends up separating the employees and the supervisors. The attitude and approach of Kenny required 100 percent commitment.
3. There is no promotion of best supervisor in the team but there cab be more done by the supervisor if he teaches the supervisors in his current position to adopt his approach. If he helped to mirror his approach and let other supervisors adopt his style then it will encourage the team to perform better. He can promote his approach in a better way.
4. Kenny is a servant leader and he effectively listens to the things people have to tell to him. The complaints and gripes are addressed in an effective manner. There is persuasion done by him for doing the job that are necessary and better results are done which explains the use of foresight and experience. He feels that it is necessary for the team to have a bigger picture for its success. There is commitment given to the growth of the individual and the team.

Below are three papers to be written. There is no minimum on word c.docxtaitcandie
Below are three papers to be written. There is no minimum on word count, but they should be a nicely develop report.
1. Businesses often face difficult situations where they must choose between different unpleasant and/or undesirable alternatives. Difficult moral choices can arise in any aspect or area of business. Ethical dilemmas may appear in decisions relating to financing, purchasing, personnel hiring or firing, promotions, risk management, outsourcing, production, marketing, acquisitions, bankruptcies, etc., etc. Whenever you have competing interests and/or conflicting moral objectives, those may give rise to ethical dilemmas.
In this context, your assignment is first to identify a recent news article (published within a month of your submitting your answer) that touches on an ethical dilemma that a specific business, or an industry, either has recently faced or else must face in the near future. Based on the article that you have selected, your task then is to write a short essay describing the relevant ethical dilemma(s) at hand and discussing the various ethical dimensions of the choices that the business(es) in question either have faced or must face. As part of your answer also make sure that (1) discuss to what extent you believe different approaches to ethics and morality might yield different decisions relating to the issues at hand and (2) how you believe the issues at hand should best be handled.
Your report on this issue should be submitted as a single word or pdf file that you upload in Canvas. The article that you select should be clearly identified in a reference section at the end of your answer.
2. Dan Ariely’s research on dishonesty suggests that, regardless of how underhandedly we may sometimes act, most of us still want to think of ourselves as being well-meaning, upright, and decent. This may create a certain tension between our self-image and our more opportunistic tendencies. Still, it seems that most of us can find rationalizations for various actions that we might, upon further reflection, admit are unethical by the metrics of normative moral philosophy (deontology, consequentialism, or virtue ethics). As Ariely has also explained, this can lead us down a slippery slope. Sometimes, what starts out as mild moral sloppiness, along with just a few seemingly insignificantly dishonest actions, eventually escalates into very unfortunate situations.
In this context, your assignment is first to identify a recent business or government scandal (or disgraceful event) that was caused by unethical and/or illegal actions which most people would condemn (at least in retrospect). Next, your task is to carefully review the information that you have about the event in question. Then, in the context of Ariely’s arguments and based on the event that you selected, you need to write a short essay imagining and reconstructing how the situation in question might have started out and how it might have escalated to its eventu.

Below are the characteristics of Realism--pick one piece of literatu.docxtaitcandie
Below are the characteristics of Realism--pick one piece of literature. Then, pick three of the characteristics below and explain how the piece of literature you chose is a good example of them. This response should be (at least) 250-300 words in length.
Definitions
Broadly defined as "the faithful representation of reality" or "verisimilitude," realism is a literary technique practiced by many schools of writing. Although strictly speaking, realism is a technique, it also denotes a particular kind of subject matter, especially the representation of middle-class life. A reaction against romanticism, an interest in scientific method, the systematizing of the study of documentary history, and the influence of rational philosophy all affected the rise of realism. According to William Harmon and Hugh Holman, "Where romanticists transcend the immediate to find the ideal, and naturalists plumb the actual or superficial to find the scientific laws that control its actions, realists center their attention to a remarkable degree on the immediate, the here and now, the specific action, and the verifiable consequence" (
A Handbook to Literature
428).
Many critics have suggested that there is no clear distinction between realism and its related late nineteenth-century movement,
naturalism
. As Donald Pizer notes in his introduction to
The Cambridge Companion to American Realism and Naturalism: Howells to London
, the term "realism" is difficult to define, in part because it is used differently in European contexts than in American literature. Pizer suggests that "whatever was being produced in fiction during the 1870s and 1880s that was new, interesting, and roughly similar in a number of ways can be designated as
realism
, and that an equally new, interesting, and roughly similar body of writing produced at the turn of the century can be designated as
naturalism
" (5). Put rather too simplistically, one rough distinction made by critics is that realism espousing a deterministic philosophy and focusing on the lower classes is considered
naturalism.
In American literature, the term "realism" encompasses the period of time from the Civil War to the turn of the century during which William Dean Howells, Rebecca Harding Davis, Henry James, Mark Twain, and others wrote fiction devoted to accurate representation and an exploration of American lives in various contexts. As the United States grew rapidly after the Civil War, the increasing rates of democracy and literacy, the rapid growth in industrialism and urbanization, an expanding population base due to immigration, and a relative rise in middle-class affluence provided a fertile literary environment for readers interested in understanding these rapid shifts in culture. In drawing attention to this connection, Amy Kaplan has called realism a "strategy for imagining and managing the threats of social change" (
Social Construction of American Realism

Ethical Organizational Communication
Rachel Danner
12/3/2013 4:33:25 PM
The three governing principles of ethical communication are honesty, equity and avoiding harm (Kreps, 2011). All three are very important in ensuring that communication through advertising and marketing. Honesty means that there is truth in the information given out during interorganizational communication. This means there is no intentional deception in the information that is being given to the customers, regulators or competitors. It is very important for companies to be honest in their advertising so that customers get what they are expecting. Advertisements draw in customers, but if they get there and find there experience is different than what was advertised, they are likely to lose trust in the company and may never use them again.
An organization must also be equitable to be ethical. This means that the company practices fair and impartial practices (Kreps, 2011). Companies that are equitable do not exhibit unfair trade practices or create monopolies. This is important in interorganizational communication because it ensures that companies are fair in advertising and marketing. This means that in an ideal world there would be no unfair advertising that blames or puts down another company. Personally if I see a company that advertises unfairly like this I avoid using their products and their company as much as possible. If a company use fair advertising I use their products and promote them by word of mouth and through my social media connections.
The last ethical principle of communication is avoiding harm. This means that it is a businesses responsibility to ensure that they do as little harm to the environment and the public as possible (Kreps, 2011). This is important, especially in today’s world because of the threats of global warming and climate change. A company has a responsibility to promote environmentally friendly products and reduce the spread of harmful chemicals that may be used in manufacturing. This is important in ensuring the long-term health of the people and the planet.

Bellevue College Chemistry 162 1 Empirical Gas La.docxtaitcandie

Empirical Gas Laws (Parts 1 and 2)
Pressure-volume and pressure-temperature relationships in gases
Some of the earliest experiments in chemistry and physics involved the study of gases. The invention
of the barometer and improved thermometers in the 17th century permitted the measurement of
macroscopic properties such as temperature, pressure, and volume. Scientific laws were developed to
describe the relationships between these properties. These laws allowed the prediction of how gases
behave under certain conditions, but an explanation or model of how gases operate on a microscopic
level was yet to be discovered.
After Dalton’s atomic theory was proposed in the early 1800’s (that matter was composed of atoms) a
framework for visualizing the motion of these particles followed. The kinetic molecular theory,
developed by Maxwell and Boltzmann in the mid 19th century, describes gas molecules in constant
random motion. Molecules collide resulting in changes in their velocities. These collisions exert
pressure against the container walls. The frequency of collisions and the speed distribution of these
molecules depend on the temperature and volume of the container. Hence, the pressure of a gas is
affected by changes in temperature and volume.
You may already think that the relationships between pressure, volume, temperature, and number of
gas molecules are intuitive, based on your ability to visualize molecular motion and a basic
understanding of the kinetic theory. The simple experiments that follow will allow you the
opportunity to confirm these relationships empirically, in a qualitative and quantitative manner. In
essence, you will play the role of a 17th century scientist (with some 21st century tools!) and discover
the laws for yourself—laws and constants that are still in use today.
In this experiment, you will:
Determine the relationship between the volume of a gas and its pressure (Part 1).
Determine the relationship between the temperature of a gas and its pressure (Part 2).

The Kinetic Theory considers
gas molecules as particles that
collide in random motion.

Being able to use research and apply findings to programming is the basis for success. Knowing how to provide information to the media and then evaluating the results is a key driver. In this Assignment, you will have an opportunity to observe and evaluate public relations at work in real events and situations. It may be challenging to identify the role of public relations in a situation. You will find it helpful to look at the source for the information - for example, company reports, independent research, or a third party. Look also at how the information was delivered - for example, whether by a spokesperson, company website, or press conference.
To prepare:
Choose a news story from your Weekly News Review. The story you select should involve a topic or situation in which public relations had a role such as community or consumer issues or products, finance or investment, sports or entertainment, government affairs, nonprofits, or corporate change, such as restructuring, new management, or new product development. The situation in the story should also meet the following criteria:
It involves more than one of the organization's target audiences.
It appears in more than one type of media outlet.
It is significant or complex enough to require involvement from top management (as spokesperson, as authority, etc.).
In a Word document, complete the following steps:
Write three media relations

Being competitive is very different than achieving sustainable com.docxtaitcandie
Being competitive is very different than achieving sustainable competitive advantage. Achieving competitive advantage needs to be a core part of strategy and instilled within the management philosophy so that the organization will continually be innovative and entrepreneurial and this strategy is the foundation of the organizational culture. Competitive advantage requires organizations to do the following:
· Adapt to external environmental changes
· Be customer driven and focused
· Have flexible strategies and processes that can meet the needs and diverse requirements of customers, suppliers, distributors, regulators, and stakeholders
· Be able to quickly respond to the fast pace of change in the environment by recognizing and taking advantage of opportunities that emerge
· Proactively meet and exceed the needs of customers in light of existing competition
· Actively engage in R & D to continuously prioritize the development of new products, services, processes, markets, and technologies
Organizations that are more adaptable, focused, flexible, responsive, proactive, and engaged in R & D are in a more favorable position not only to adapt to the complex, dynamic external environment but to generate change within that environment and sustain competiveness. Innovation and entrepreneurship are the key sources of sustainable competitive advantage as evident from leading entrepreneurs such as Richard Branson (Virgin Group), Bill Gates (Microsoft), Pierre Omidyar (eBay), and Mark Zuckerberg (Facebook). Continuous innovation, entrepreneurial activity, and an ability to bring about positive changes are the key success factors (KSFs) that define corporate performance in the dynamic, complex, knowledge economy of the 21st century.
The Role of Innovation, Entrepreneurship, and Strategy in Achieving Sustainable Competitive Advantage
Innovative and entrepreneurial organizations develop a strategy that can effectively lead to the commercialization of the new and novel products or services in the marketplace with a sustainable competitive advantage. Strategic management and entrepreneurship are dynamic processes that are intended to enhance organizational performance (Kuratko & Audretsch, 2009). Strategic management focuses on how competitive positioning can create advantages for organizations that, in turn, enhance performance (Porter, 1980, 1996) and achieve sustained competitive advantage. Strategic planning requires top management to focus beyond the current external environment and envisage the organization's market position in the short, medium, and long term. It necessitates the ability to evaluate the resources and core competencies in terms of how they can be utilized to create new sources of value.
Innovation and entrepreneurship are the key to successfully developing competitive advantages. The challenge is to develop innovation and entrepreneurship as a core competence of the organization. In a global competitive economy, the most successf.
Being enrolled in the MS in Child and Adolescent Developmental Psych.docxtaitcandie
Being enrolled in the MS in Child and Adolescent Developmental Psychology program has truly added to my personal and professional growth. First of all, the program has allowed me to virtually meet many colleagues within the educational/psychology field. I have learned a lot from reading my colleagues discussions and opinions. The program has allowed me to organize my time better and become more responsible. For example, many personal plans were cancelled due to studying (which I have learned to appreciate).
As an elementary teacher, I normally used to refer Special Educational Needs students to the school’s SEN department. There is only so much you can do as a teacher! However, this program has helped me understand learning disabilities, developmental pathways, psychological disorders and much more. I’ve found the course material to be very useful when it comes to interventions and helping children. Now, I can hopefully utilize my new knowledge in the classroom. Most importantly, this program has taught me to become more sensitive towards the unique needs of children/adults.
Being an advocate of social change is important. “In many societies around the world, teachers are looked upon as the individuals who can help to bring about positive changes in the lives of people.” (Bourn, 2016, p. 63). Learning, global education and education development are closely related to personal and social change elements (Bourn, 2016). Studies suggest that teachers need to look beyond raising awareness of specific issues; they needs to encourage students to have their own voice, take action and promote their own unique skills to make a difference (Bourn, 2016). The MS program has taught me to create my own mission of social change to inspire children (students) to act in positive manners. I will try my best to be a social change agent within my classroom by fighting harmful stereotypes, applying theory/ evidence based information to practice, creating an anti-bias environment and educating ‘the whole child’, focusing on their social-emotional development in addition to their learning experiences. To contribute to social change, I must be knowledgeable about specific problems and the reasons contributing to those problems. To contribute to social change, I will try to allow students to practice how to think, instead of what to think.
Finally, one person who has truly offered their support during the entire program is my husband, Karim. Karim has offered much emotional support and encouragement during these 2 years, he also offered help and advice. These 2 years have passed by very quickly! He was truly patient and understanding while listening to many of my psychological analyses (many of them could be wrong I presume :D) . I dedicate my degree to him and ofcourse to all my colleagues and professors in the program who were supportive.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

[Flight Simulation]
[ 15 marks ]
A new jet aircraft are subjected to intensive flight simulation
studies before they are tested under actual flight conditions
.
In these studies, an important relationship is that between the
mach number (percent of the speed of sound) and the altitude of
15. the aircraft
.
This relationship is important to the performance of the aircraft
and has a definite impact in making flight plans over populated
areas
.
If certain mach levels are reached, breaking the sound barrier
(sonic booms) can result in human discomfort and light damage
to glass enclosures on the earth’s surface
.
Current rules of thumb establish crisp breakpoints for the
conditions which cause performance changes in aircrafts, but in
reality these breakpoints are fuzzy, because other atmospheric
conditions such as the humidity and temperature also affect
breakpoints in performance
.
For this problem, suppose the flight test data can be
characterised as “near” or “approximately” or “in the region of”
the crisp database breakpoints
.
Define a universe

[Laser Beam Alignment]
[ 35 marks ]
Fuzzy logic is used to control a two-axis mirror gimball for
aligning a laser beam using a quadrant detector
28. .
Electronics sense the error in the position of the beam relative
to the centre of the detector and produces two signals
representing the x and y direction errors
.
The controller processes the error information using fuzzy
logic and provides appropriate control voltages to run the
motors which reposition the beam
.
The fuzzy logic controller for this system is shown in Figure 2
.
1
.
To represent the error input to the controller, a set of linguistic
variables is chosen to represent 5 degrees of error, 3 degrees of
change of error, and 5 degrees of armature voltage
.
Membership functions are constructed to represent the input
and output values’ grades of membership as shown in Figure 2
