Learn Digital Logic and Microprocessor Design with VHDL

5:06 PM
Digital Logic and  Microprocessor Design  with VHDL  (soon with Verilog)- Enoch O. Hwang, La Sierra University, Riverside, CA. This book will teach students how to design digital logic circuits, specifically combinational and sequential circuits. Students will learn how to put these two types of circuits together to form dedicated and general-purpose microprocessors. This book is unique in that it combines the use of logic principles and the building of individual components to create data paths and control units, and finally the building of real dedicated custom microprocessors and general-purpose microprocessors. After understanding the material in the book, students will be able to design simple microprocessors and implement them in real hardware.

Numerical Analysis For Differential Equation Solution

1:25 PM
1. Introduction
Differential equations play an important role in many problem of engineering and science. This is so because of the involvement of differential equation in the mathematical models. It naturally leads to the determination of solution numerically. The use of the numerical methods have become vital in the absence of explicit solutions. Normally numerical methods have two major roles:
(a) the method should be implementable on a computer;
(b) the method should deal with the analysis of error estimates.
For the present we deal with some of the numerical methods to solve initial value problems (IVP's) (on finite intervals). We also mention that no effort is made to study boundary value problems. Let us consider an initial value problem.

Papers About Theory of planned behavior

3:39 PM
TPB posits that individual behavior is driven by behavioral intentions where behavioural intentions are a function of an individual's attitude toward the behaviour, the subjective norms surrounding the performance of the behavior, and the individual's perception of the ease with which the behavior can be performed (behavioral control). Attitude toward the behavior is defined as the individual's positive or negative feelings about performing a behaviour. It is determined through an assessment of one's beliefs regarding the consequences arising from a behavior and an evaluation of the desirability of these consequences. Formally, overall attitude can be assessed as the sum of the individual consequence x desirability assessments for all expected consequences of the behavior. Subjective norm is defined as an individual's perception of whether people important to the individual think the behavior should be performed. The contribution of the opinion of any given referent is weighted by the motivation that an individual has to comply with the wishes of that referent. Hence, overall subjective norm can be expressed as the sum of the individual perception x motivation assessments for all relevant referents. Behavioral control is defined as one's perception of the difficulty of performing a behavior. TPB views the control that people have over their behavior as lying on a continuum from behaviors that are easily performed to those requiring considerable effort, resources, etc. Although Ajzen has suggested that the link between behavior and behavioral control outlined in the model should be between behavior and actual behavioural control rather than perceived behavioural control, the difficulty of assessing actual control has led to the use of perceived control as a proxy.

Topical worksheets

Together, these worksheets constitute a body of questions far too large to be comprehensively covered in any single electronics course. That is not the point, though. This collection is purposely oversized so you may pick and choose enough questions to meet your specific teaching needs. Download those worksheets containing questions you wish to use, and then only assign those questions to your students for research and discussion. The rest may be ignored, or your students may find them useful as study aids outside of class.

Although I strive to make each of these worksheets self-contained, some topics will (necessarily) assume coverage of prior topics. For instance, it would be impossible for a beginning student to understand a worksheet on series-parallel resistor circuits without first having understood Ohm's Law.
