  • Algorithm is used to define the notion of decidability. It is a set of rules that precisely defines a sequence of operations. This is essential for computers to process information. Computer programs contain algorithms that detail specific instructions a computer should perform to carry out a specified task. The traditional computer program performs specific instructions sequentially, and uses crisp values of information which do not support uncertainties.

  • The first 11 chapters of this text focused on manufacturing test. Its purpose is to answer the question, “Was the IC fabricated correctly?” In this, the final chapter, the emphasis shifts to design verification, which attempts to answer the question, “Was the IC designed correctly?” For many years, manufacturing test development and design verification followed parallel paths. Designs were entered via schematics, and then stimuli were created and applied to the design.

  • I have noticed over the years that students have great deal of difficulty dealing with composite and abstract data types. Therefore we are going spend an extra lab review material we have already learned. Vector data type, a variation of array, will be introduced as well. Vector data type (Vector Class) can be used when you need an array that grows dynamically. However, C++ does not allow us to declare size of an array dynamically like some other languages. It is important for you to declare the maximum size you will need. Suppose you are writing a program to keep...

  • Standard IR systems can process queries such as “web NOT internet”, enabling users who are interested in arachnids to avoid documents about computing. The documents retrieved for such a query should be irrelevant to the negated query term. Most systems implement this by reprocessing results after retrieval to remove documents containing the unwanted string of letters. This paper describes and evaluates a theoretically motivated method for removing unwanted meanings directly from the original query in vector models, with the same vector negation operator as used in quantum logic. ...
