Introduction
• Problem solving
• The mere formulation of a problem is far more essential than its solution, which maybe merely a matter of mathematical or experimental skill. To raise new questions, new possibilities, to regard old problems from a new angle requires creative imagination and marks real advances in science. » Albert Einstein



Problem statements
– “A problem well stated is a problem half solved.”
• Charles Kettering (Early pioneer of automotive research)

Project Definition Instruction set architecture (ISA) describes the processor in terms of what the assembly language programmer sees the instructions and registers. All computer programs are translated to machine code for execution by the CPU. Once a program has been loaded into the computer’s memory. The program may then be executed. Many modern processor designs are so called RISC (Reduced Instruction Set Computer) designs which use relatively small instruction sets, in contrast to so called CISC designs such as the VAX and machines based on the Intel 8086 and Motorola 68000 microprocessor families. Operating instructions also include instructions that move data between registers and manipulate stacks. Memory-access instructions are those that transfer data between registers and memory. The CPU carries out the instructions that it finds in the...

...Unit III: Chapter 7 Assessment of Learning Guiding Principles in the Assessment of Learning 1. Assessment of learning is an integral part of the teaching-learning process: It is logical to find out how well we have attained our lesson objective, thus we engage ourselves in the process of assessment. What do we do after teaching is determined by the result of assessment. 2. Assessment tool should match with performance objective: The assessment tools that are used to evaluate the students should be aligned with the performance objective you expect from your students so that the assessment will be valid for evaluation purposes. 3. The results of assessment must be fed back to the learners: The main purpose of assessment is to find out how well the learner has attained a particular learning objective. Thus, the results of the assessment should be given to the students so that they’ll be able to know if they are progressing or not. 4. In assessing learning, teachers must consider learners’ ;earning styles and Multiple Intelligences and so must come up with a variety of ways of assessing learning: Educators should consider the different learning styles and multiple intelligences of the students. Therefore, we should make assessments that would focus as many learning styles and multiple intelligences as possible. 5. To contribute to the building of the culture of success in the school, it is pedagogically sound that in our assessment techniques...

I choose Lexus and Hawk knitwear. Lexus is the luxury vehicle division of Toyota. It was first introduced in 1989 in the United States.

It is very important to develop new cars every 2 years. They need to develop extra tools for the car, that you can buy when you already have a car, or which you can get as a gift when you buy a new car. Diversification is an important thing at Lexus, because they have business clients and private clients. Each client will have another special thing they want and Lexus has to fulfill their expectations. Brand building and positioning Lexus started in 1989, in the United States of America. It all begun with the question; can we create a luxury vehicle to challenge world’s best? Toyota started a top secret project, F1 and when they finished the project, the Lexus LS400 was developed.

GACUSAN, Ph. D. DEDICATED TO OUR PARENTS OUR FRIENDS LOVED ONES AND OUR ALMIGHTY GOD Table of Contents Chapter 1- INTRODUCTION Background of the Study 1 Objectives of the Study 2 CHAPTER 1 PROJECT BACKGROUND Background of the Study A grading system is a great help to students and to the school Administrator in maintaining and monitoring students’ performance. It will be easy for the students to determine their grades in every subject taken especially right after the end of a semester. A student final grade is a result of class activities, quizzes, and major examinations. Grades are given based on point systems and most schools encounter problems in recording student grades due to manual method of handling students’ grades. It is very important for every school to have a systematic and upgraded system in keeping or recording of grades. This was the reason this study on computerized grade monitoring system was conducted by the information technology of East Pacific Computer College so that as students transact with the registrar to ask for their grades, it could be easy for the registry office to release the grades of the students instantly. A grading system could be a great help, not only for the students but also for the school administration for the enhancement of the...

Acct311 Unit 3 Discussion Board

...ACCT311 Unit3 - Discussion Board Consider the following scenario: Jim’s Music Company uses LIFO for inventory, and the company’s profits are quite high this year. The cost of inventory has been steadily rising all year, and Jim is worried about his taxes. You are Jim's accountant and you suggested that the company make a large purchase of inventory to be received during the last week in December. You explained to Jim that this would reduce his income significantly. Jim still doesn't understand the logic of your suggestion. Explain how the purchase would affect taxable income. (1 paragraph) Is this ethical? Jim is uncertain about the appropriateness of this from a legal and ethical perspective. Give your opinion and explain the ethical implications of making the purchase. (1 to 2 paragraphs) I would tell Jim that if he was to make the large purchase close to the end of the year, it would leave his taxable income lower due to the unsold inventory. There wouldn't be anything unethical about this transaction because it would all be recorded into the proper categories. I work for a large corporation and in my department; my manager tells me that we need to buy all we can during the last quarter. She tells me that this will help our projected budget for the upcoming year. I feel that this is a similar situation. If Jim didn’t make the purchase, leaving his end of year net come high, the big boss can lower the budget for the next year for the inventory purchases...

Biology

...FACTORS AFFECTING THE RATE OF DIFFUSION I) Surface Area vs. Volume   - Cells are limited in their size because they must maintain a high “Surface Area : Volume” ratio. - Nutrients (oxygen and glucose) must enter a cell while wastes (carbon dioxide and urea) must exit a cell through the cell membrane. - The amount of cell membrane = Surface Area of the cell.   - Inside the cell, organelles use up nutrients and produce wastes. The larger the cell, the more nutrients needed and the more wastes produced. - The size of the cell (based on the number of organelles) = Volume of the cell.

If a cell gets too big, wastes will build up and nutrients will run out; cell cannot survive.   - Therefore, cells are limited in their size. The more active a cell the smaller it must be. Active cells need more nutrients and they produce more wastes.   - How do cells occupy the large volumes associated with large organisms? The cells reproduce frequently through mitosis to maintain their small size (high “SA:Volume”...

...Reflection Sanquinetta Davis, Victoria Miller, Tamika Garbutt-Taylor, Sarah Billingham, Shunta Dow QNT/351 September 15, 2014 Mark Salaaka Reflection “The hypothesis guides us on the selection of a certain design, observation and methods of researching over others. If we could test the whole populations directly, we would not need to formulate hypothesis, conduct inferential statistics and make inferences for the population based on a sample. However, it is often impossible to test the whole population, and we need to make our observations based on a sample (University of Strathclyde Humanities & Social Studies, n.d.).” “Hypothesis testing is all about populations and using a sample based in which we make inferences about the population” (University of Strathclyde Humanities & Social Studies, n.d.). The basic logic is to prove or disprove the research question. There are five steps that consist of all the decisions a researchers needs to make in order to answer any research question. Steps in Testing a Research Hypothesis 1. Stating the Research Question. “This step makes the researcher not only define what is to be tested but what variable will be used in sample data collection” ("Five Steps of Hypothesis Testing", 2014). 2. Specify the Null and Alternative Hypothesis –  According to the University of North Carolina (2014), "The second step is to state the research question in terms of a null hypothesis (H0) and a alternative hypothesis (HA)...
