: System View of the Project3. Implementation Issues and ExtensionsAs shown in Figure 1, there are four programs, X1, X2, Y1, and Y2 that work together but arelaunched separately to create the illusion required in the assignment. The students quicklyrealize that one needs multiple clients and servers. Program X2 has two subprograms, a BSDserver component (X2bsd-s) and a TCP/IP client component (X2tcp-c). Similarly, program Y1has two subprograms, a TCP/IP server part (Y1tcp-s) and a BSD client (Y1bsd-c). Module X1 isa BSD stack client for BSD stack server X2bsd-s while module Y2 is a BSD stack server forBSD stack client Y1bsd-c. Further, X2tcp-c is a client of the TCP stack server Y1tcp-s. Themodules are launched from right to left. Server Y2 is

This paper reviews the historyof the changes in electrical engineering departments in the United States to incorporatecomputers. It ends with projections into the next century of the challenges ahead.II. The Early Years (Before 1960) The early years of computers coincided with rapid growth in many other areas ofelectronics to which electrical engineering departments, as they were then almost universallycalled, had to adapt. World War II saw great advances in radar and a recognition of the need formore research and graduate education, which greatly impacted electrical engineering departmentsin the 1940's and 1950's. The need for education in electronics gradually crowded out

This ∆f can be interpreted as the width of a frequency bin that is centered onfcent. The smaller the width of the bin, the higher the resolution of frequency. It is important tonote that changing the sample size or sampling rate will change the resolution, and that changingsampling rate alone modifies both the Nyquist cut-off frequency and the center frequency.

This paper reports on the first of these two questions.KBTS AS A PERSONALITY MEASURERThe KBTS uses much of the same construct as the MBTI. With the KBTS and MBTI, personalitytypes are derived from four preference scales. These dimensional scales are: Extroversion -Introversion (E-I), Sensation - Intuition (S-N) , Thinking - Feeling (T-F), and Judgment -Perception (J-P). The KBTS uses 70 questions (less than the MBTI) written to test preferenceswith respect to the four preference scales. There are sixteen unique “personality types” formedfrom the four personality preference scales (24=16). Example personality types would

The SF6 in the flowexiting the dryer is measured with an electron capture detector (ECD), and pumps are located atthe downstream end of the flow system to minimize dead volume and response time(approximately 0.5 s). The output from the ECD is an analog voltage signal (0-5 V) which canbe directed to a data acquisition system for storage. The lower detection limit with the RydockScientific microanalyzer is about 5 pptv. The instrument weighs 4.5 kg, is 46 cm by 15 cm by 30cm in size, and can operate on battery power in the field.
