Why Cost Estimation? Critically important part of system design Too high – lose the contract award Too low – over-run cost plus contracts, company loss on fixed price contracts

Storage relative difficulties involved in their avoidance vary with location. Successful storage methods Compared with many other fruits, cereal grains are extremely amenable to storage, principally as range from primitive to highly sophisticated their moisture content at harvest is relatively low The hazards besetting cereal grain storage are: and their composition is such that biodeteriora-- moisture content; tion is slow. Harvesting is seasonal but the need -excessive temperature; for fresh cereal products is continuous. The least Anicrobial infestation; requirement for storage, therefore, is for the -insect and arachnid infestation;

10.1 Basic definitions A failure is an unacceptable behaviour exhibited by a system —The frequency of failures measures the reliability —An important design objective is to achieve a very low failure rate and hence high reliability. —A failure can result from a violation of an explicit or implicit requirement

Later in the course we shall review various methods of designing frequency-selective filters satisfying prescribed specifications We now describe several low-order FIR and IIR digital filters with reasonable selective frequency responses that often are satisfactory in a number of applications

Air Buoyancy Akin to water keeping something afloat, samples can be “lifted” by air, artificially decreasing their apparent weight. This air buoy￾ancy can have a significant effect on smaller samples. Electrostatic Forces Electrostatic charges are almost always present in any environ￾ment, particularly in areas with very low humidity. If there are

compromised body in low numbers), organisms that are normally nonpathogenic can cause infection. The infectious dose will vary with the organism and the health of those infected. For example, Shigella flexneri requires the ingestion of only a few hundred organisms to cause intestinal disease. Salmonella typhi requires
