SIAM REVIEW Vol. 41‚ No. 1‚ pp. 135–147 c 1999 Society for Industrial and Applied Mathematics The Discrete Cosine Transform∗ Gilbert Strang† Abstract. Each discrete cosine transform (DCT) uses N real basis vectors whose components are π cosines. In the DCT-4‚ for example‚ the jth component of vk is cos(j + 1 )(k + 1 ) N . These 2 2 basis vectors are orthogonal and the transform is extremely useful in image processing. If the vector x gives the intensities along a row of pixels‚ its cosine

improve the quality of education. The teacher is the only source of information during the class‚ but now using this system is more effective for students to improve their knowledge. Today‚ students learn in the most and to the great extent if they will learn it through doing it by themselves. By introducing this type of teaching strategies‚ E-Module for Discrete Structures with biometrics is made to enhance the quality of education and instruction inside the classroom.

Rapid Surveys (unpublished)‚ © 2008. NOT FOR COMMERCIAL DISTRIBUTION 3 Simple Random Sampling 3.1 INTRODUCTION Everyone mentions simple random sampling‚ but few use this method for population-based surveys. Rapid surveys are no exception‚ since they too use a more complex sampling scheme. So why should we be concerned with simple random sampling? The main reason is to learn the theory of sampling. Simple random sampling is the basic selection process of sampling and is easiest to understand

Probable Probability; Rolling Dice Statistics is based upon based upon common sense and logic‚ in a complex data. Probability is just one of the many topics in statistical mathematics. It is used in our daily life‚ all over the world. Even games‚ require taking a chance and using probability to determine the predicted outcomes. Probability is the measure of how often a particular event will happen if something is done repeatedly‚ (596 Webster’s Dictionary). You cannot determine

What is continuous improvement means in the context of organisational success Continuous improvement is a quality philosophy that assumes further improvements are always possible and that processes should be continuously re-evaluated and improvements implemented. It is also the seeking of small improvements in processes and products‚ with the objective of increasing quality and reducing waste.

4. Risk of moderator variables during assessment A moderator variable is a variable that may affect the relationship between two other variables. As such‚ predictors and criteria for some candidates who have a particular score on the moderator variable could display different relationships than the predictors and criteria of other candidates‚ who have an alternative score on the moderator variable. Examples of moderator variables could include gender‚ age‚ length of service‚ and nationality (Spector

explanation based on a systematic comparison of one ‘thing’ with another‚ already known ‘thing’.” From this definition ‘analogical reasoning’ can be described as‚ reasoning where decisions about a presented ‘problem’ are made depending on comparisons and similarities between that ‘problem’ and a known situation. In order to determine when problem solving can be aided by analogical reasoning it is first necessary to look more closely at the concepts of ‘problems’ and ‘problem solving’. A ‘problem’
