The steel rope is wound onto a lifting drum with a diameter of 700 mm and rotational frequency of 56 revolutions per minute. The lifting drum is situated on the top floor which is 195 m high. How many seconds will it take to lift bricks, three quarters up the height of the building? Pylyshyn and Kosslyn disagreed about the nature of visual imagery. Explain what the disagreement was about. Describe and evaluate the behavioral evidence suggesting that ""seeing with the minds eye"" involves similar processes to perceiving external objects in the real world. Why did Timothy C. Lim identify one particular type of cultural analysis as being bad analysis and something to avoid? a) Explain how Organizational Behavior (OB) concepts can help and make organizations more productive? b) Explain the major "challenges and opportunities" for managers to use Organizational Behavior (OB) concepts. c) Imagine yourself as a financial manager, Recommend the type of leadership style do you prefer to adopt and discuss your reasons? Problem 5 (2 points) Band pass filters are often used to filter out low and high frequency noise. A simple passive band-pass filter can be constructed by combining a RC high-pass filter in series with a RC low-pass filter as shown in the following diagram. Here the block Hp(s) is the transfer function of the high-pass filter, and Hp(s) is the transfer function of the low-pass filter, and Vin (s), Vout(s) are the Laplace transforms of the input and output voltages, respectively. Vin (s) HHP(S) HLP(s) Vout(s) Starting from the transfer functions of the passive low-pass RC and passive high-pass RC filters, and using (a useful) property of Laplace transforms, determine the transfer function of the band-pass filter (aka determine the transfer function of the cascade-connected system). Problem 10 (Extra Credit - up to 8 points) This question builds from Problem 5, to give you practice for a "real world" circuit filter design scenario. Starting with the block diagram of the band pass filter in Problem 5, as well as the transfer function you identified, please answer the following for a bandpass filter with a pass band of 10,000Hz - 45,000Hz. You may do as many, or as few, of the sub-tasks, and in any order. 1. Sketch the Bode frequency response amplitude and phase plots for the band-pass signal. Include relevant correction terms. Label your corner frequencies relative to the components of your band-pass filter, as well as the desired corner frequency in Hertz. (Note the relationship between time constant T = RC and corner frequency fe is T = RC 2nfc 2. Label the stop bands, pass band, and transition bands of your filter. 3. What is the amplitude response of your filter for signals in the pass band (between 10,000Hz 45,000Hz)? 4. Determine the lower frequency at which at least 99% of the signal is attenuated, as well as the high-end frequency at which at least 99% of the signal is attenuated. 5. What is the phase response for signals in your pass band? Is it consistent for all frequencies? 6. Discuss the degree to which you think this filter would be useful. Would you want to utilize this filter as a band-pass filter for frequencies between 10,000 - 45,000 Hz? What about for a single frequency? Is there a frequency for which this filter would pass a 0dB magnitude change as well as Odeg phase change? 1. Determine THREE (3) factors influencing the selection of ground improvement techniques. The proposed construction area for the new administration building for the LIMKOKWING University is located on the soft soil which is not suitable to support the structure over them. Ground improvement may be proposed for the safe construction process.2. Identify the factors that are affecting the soil compaction. In the construction of highway embankments, earth dams, and many other engineering structures, loose soils must be compacted to increase their unit weights. Compaction increases the strength characteristics of soils, which increase the bearing capacity of foundations constructed over them. The HIV/Aids unit on campus wants to change the attitudes of students relating to risky sexual practices as these contribute to the spread of the disease. They plan to invite a speaker who is HIV positive. Explain the main factors that the speaker will need to consider in order to ensure that his/her message is effective in changing the attitudes of students. Focus on both the characteristics of the message and of the speaker. (10) LAW QUESTION ( MUST USE IRAC METHOD) A and B are friends. A asks B, an accountant, if she should invest in X company. B explains that she has checked the accounts of X, and that it is a good investment. In fact, B misread the accounts and the company is insolvent. A invests her money, and her investment fails. Advise A of her rights and support your answer by reference to at least one (1) court case. Please use IRAC method.
