Analysis of Articles about Gender Studies - Essay Example She told them she always thought she had three. And that showed the extended family that the author seems to enjoy. For every person who is a part of the extended family, the author and her growth were more important than anything else. This made everything else immaterial. As the author points out, the pre-conceiving arrangement that the mothers went through ensured that the differences in their thought processes will not occur. There was enough leeway created between all of them and freedom to change their decisions. So much so that no one altered any of the decisions that were made. This made the entire process of bringing up the kid more interesting to the extended family. She was no ordinary child and whatever happened to every one of them was not an ordinary event. The author finally, justifies that the ideas and the opinions taken should be done so in the right spirit and this would ensure that the biotechnological advances made are used in the right spirit. There was nothing wrong or unnatural in the entire process. She does not feel in any way different from the others and neither did anyone else feel that way though many thought she was special. The questions will be: Creation of a human being either by cloning or by IVF methods is out of nature. Will this not give rise to a culture that has the least respect for the natural phenomenon? And will not this lead to a condition where the human race might overpopulate or try to control nature which otherwise could condition the environment in a much better way? While so, how can control and modifying natural occurrences influence the behavior of the human race? All these issues are not really dealt with by the author. When the perspective goes larger those questions come up. Whereas in the case of the author's analysis, she has restricted to her own view and to the views of the people around her.

Logic gates characteristics - Lab Report Example Also, an XOR (Exclusive- OR) which is sometimes called an inequality comparator implements the expression such that â€Å"if A is different than B then X is true. Sometimes a buffer may be used between the inputs and output of a logic circuit. The buffer helps to increase the fan-in of the circuit. The XOR gate is commonly used as a buffer to supply a 0 or a1to one of its inputs. Multiplexers behave like rotary switches and select any one of its inputs as output. It is a combination of logic gates thereby having several inputs with only one output. The input channel to be read into the output is controlled by supplying a definite digital word to the select inputs. In experiments using microelectronic chips such as the Multiplexer ICs, care should be taken when handling so as not to expose the chips to static hazards. The input lines to a multiplexer chip are 2, 4, 8 or 16 that supply the output one at a time. They are used to reduce the number of logic gates required to implement th e circuit. Digital multiplexers are constructed from analogue switches encased in a single IC package. The multiplexer is used in signal routing, data communications and data bus control. They can be used together with a demultiplexer to transmit parallel data in serial form through a single data link e.g. fibre optic cable. Multiplexers are also used a A/D converters thereby reducing the amount of heat dissipated (Bate, 1988). Aim To use a digital logic circuits to decode an industrial control system, and to test an equivalent logic decoding circuit using a multiplexer chip. Procedure The control system of a bottled water factory is designed to follow specific process to control the filling upon receiving specific instructions. The process will halt with logic zero output. The processing plant sensors produce logic level outputs for the following devices. B – Bottle Position Correct Position= logic 1, and an incorrect position = 0 W – Water level low Water level low = logic 0, and water level satisfactory = 1 V – Flow Valve Position: Flow valve open = logic 0, and flow valve closed = 1 F – Water Filtration System: Filtration blocked= logic 0, and filtration working = 1 This process is halted on the following conditions: When the bottle position is incorrect and it is filling and this is indicated by an open flow valve. Or if the water level is low, but not when the flow valve is open. Also, if the Filtration is blocked, but only if the Flow valve is closed and the water level is not low. Also, if the Flow valve is open, and if the bottle position is incorrect or water level remains low. Discussion Full truth table of the industrial control process is shown below; The above conditions for halting the process can be simplified as shown here under, Position, P = 0 if; 1). (B= 0).(V=0) 2). (W = 0) (V= 0) = (W = 0). (V= 1) 3) (F = 0). (V= 1). (W = 1) 4). (V = 0). (B = 0). (W= 0) P= X: (V=0). (W=1) Truth Table. The above truth table can be simplified using the Karnaugh Map shown below; From the K- map it is clear that P = W.F. This can be implemented using the circuit shown below; B W V F P The circuit was built using the 74LS151 microchip as shown below and tested to find out if the desired result is obtained. The output Z was tested and found to follow the truth table shown here under, The tested output is found to quite agree with the results in the first truth table.
