Virtual Teams and Non-Verbal Clues

Many believe that non-verbal clues (e.g. facial expressions and body language) are better indicators of the real (unspoken and unwritten) message that is being delivered. We tend to seek, and are reassured by, congruence between these two layers of communications, when building trust and forming teams. Face-to-face contact would

People, Technology and Management - Learning and Improving Performance

Would you be able to help me get started on the following: Learning is characterized as "any relatively permanent change in behavior that occurs as a result of experience." This also means that it also happens outside of schools, e.g. at workplaces. Give an example of such a "lesson" that helped you to improve your job p

Natural Languages versus Computer Languages

We know there are problems of understanding natural languages as opposed to formal programming languages. As an example of the complexities involved in the case of natural languages, identify situations in which the question "Do you know what time it is?" has different meanings.

RISC machine assembly: delayed branching

Consider the following loop: S:= 0; for K := 1 to 100 do S : = S - K; A straightforward translation of this into a generic assembly language would look something like this: LD R1,0 ;KEEP VALUE OF S IN R1 LD R2,1 ;KEEP VALUE OF K IN R2 LP SUB R1,R1,R2 ;S := S - K BEQ R2,100,EXIST ;DONE IF K = 100 ADD R2,R

Significance of RDF

What are the various reasons that make RDF data model essential to store data, rather than using xml or relational model? Include references.

Designing a class

Object oriented design is creating classes with both characteristics and behavior wrapped together (called encapsulation). Taking data (characteristics) and the functions (behavior) that operate on that data and storing them as one programming unit (called a class) is extremely powerful. When completing a class design it is cr

Signal Encoding: NRZ-I, Samples per second

1. Provide diagrams of the NRZ-I, Manchester, and bipolar-AMI encodings for the following bit stream: 011101101 2. How many samples per second are required to digitize the following signals to avoid aliasing in the reconstructed signal: a. Signal bandwidth less than 30,000 Hz b. Signal bandwidth less than 1 MHz c.

Constant and Variable in a Program

1. What is a data type in C? Describe two data types and how they might be used in a C program. 2. What is the difference between a constant and a variable in a program? Why would you use one or the other?

A distributed software application case study

Should the recommendation be for each 'branch' grocery store to be connected to the 'central' grocery store software? As an example if (me) a customer purchases (say three boxes of cereal and 1 gal. of milk) at a branch store, the clerk checks my purchases out and obtains a cash receipt. Shouldn't the 'software' recommendation

Discussing Variables and Constants

Define and study the terms "variable" and "constant" as used in computer programming. Determine the various types of data (such as char, int, double, string, and date) that can be used in developing a solution. Describe how and when you would use one over the other in a simple solution to calculate the grade average for a class.

Proof by Contradiction

Prove the following fact (give a proof by contradiction): There do not exist constants N > 0 and C > 0 such that ∀n ≥ N ,n^2 ≤ C*n

UDP and multicast

Describe and discuss what the UDP does and its relationship to TCP - in what ways is it similar and different, and why (what applications) would we use UDP, and why can't a user program access IP directly? What is multicast, how is it used, also include some of the constraints and solutions to those constraints. Provide a

Write a Program to Calculate Weekly Pay
