Chapter 5: Flow Rate and Capacity Analysis 5.1 Objective Chapter 3 introduced the three basic building blocks of process flow namely the (average) flow time‚ (average) flow rate and (average) inventory. It is followed by a sequence of three chapters‚ 4‚ 5 and 6‚ which examine each one of these measures individually. Chapter 5 is concerned with flow rate analysis and issues of capacity. The major managerial concept discussed in the in the chapter is that of the bottleneck. We use the notion

appears a common problem; with different loads used by the consumers there is fluctuation in the turbine speed and hence the frequency generated by the generator which causes adverse affect in various electrical appliances. So in order to control the voltage of synchronous generator‚ its excitation is controlled; whereas the frequency can be controlled either by controlling of value of mechanical power input to the generator or by varying the electrical load. Mechanical power input can be controlled

1. _____________ is the ability of a central processing unit (CPU) or a single core in a multi-core processor to execute multiple processesor threads concurrently A. Answer : multithreading B. Multicore C. Multiprocessor D. None of these 2. Multiple threads can interfere with each other when sharing hardware resources such as caches or translation lookaside buffers (TLBs). As a result‚ execution times of a single thread are not improved but can be degraded‚ even when only one thread is executing

LM317‚ NCV317 1.5 A Adjustable Output‚ Positive Voltage Regulator The LM317 is an adjustable 3−terminal positive voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of 1.2 V to 37 V. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. Further‚ it employs internal current limiting‚ thermal shutdown and safe area compensation‚ making it essentially blow−out proof. The LM317 serves a wide variety
