As the reader of this book probably already knows, I have devoted a great deal of time to the topic which is, rather unfortunately, named rent seeking. Rent seeking, the use of resources in actually lowering total product although benefiting some minority, is, unfortunately, a major activity of most governments. As a result of this, I have stumbled on a puzzle. The rent-seeking activity found in major societies is immense, but the industry devoted to producing it is nowhere near as immense. In Washington the rent-seeking industry is a very conspicuous part of the landscape. On the other hand,...

BY H. KOPETZ A real-time computer system must provide the intended service in two di mensions: the functional (value) dimension and the temporal dimension. The verification of a real-time system implementation is thus necessarily more com plex than the verification of a non-real-time system which has to be checked in the value dimension only. Since the formal verification techniques of temporal properties have not yet matured to the point where these techniques can be used in practical system development, systematic design and testing are the only alternatives for the development of...

Testing techniques for VLSI circuits are undergoing many exciting changes. The predominant method for testing digital circuits consists of applying a set of input stimuli to the IC and monitoring the logic levels at primary outputs. If, for one or more inputs, there is a discrepancy between the observed output and the expected output then the IC is declared to be defective.
A new approach to testing digital circuits, which has come to be known as I_DDQ testing, has been actively researched for the last fifteen years. In I_DDQ testing, the steady state supply current,...

"Well informed people know it is impossible to transmit the voice over wires, and that were it possible to do so, the thing would be ofno practical value. " from an editorial in the Boston Post -1865 Fortunately for the telecommunications industry, the unknown author of the above statement turned out to be very mistaken indeed. Even as he spoke, Alexander Graham Bell was achieving the impossible, with a host of competing inventors close behind. The communications revolution which ensued has changed the way in which we live and work, and the way in which we view the world around us. Wired...

In response to the emerging need to develop teachers as professionals who evaluate their own work, this book presents the foundations of self-evaluation as well as self-evaluation models and tools that are likely to help educational practitioners to evaluate their own teaching, and thus raise the level of their professional functioning.
The book is intended to serve several groups: student teachers whose socialization into the teaching profession should include the perception of self-evaluation as an inherent part of teaching; the student teachers' supervisors who are expected to help in...

An open process of restandardization, conducted by the IEEE, has led to the definitions of the new VHDL standard. The changes make VHDL safer, more portable, and more powerful. VHDL also becomes bigger and more complete. The canonical simulator of VHDL is enriched by new mechanisms, the predefined environment is more complete, and the syntax is more regular and flexible. Discrepancies and known bugs of VHDL'87 have been fixed. However, the new VHDL'92 is compatible with VHDL'87, with some minor exceptions.

Low-Voltage Low-Power Analog Integrated Circuits serves as an excellent reference, providing insight into some of the most important issues in the field.

It is common to assert that utility investors are compensated in the allowed rate of return for the risk of large disallowances, such as arise for investments found imprudent or not used and useful'. However, this book develops a new theory of asymmetric regulatory risk that shows that infallible estimates of the cost of capital are sure to provide downward-biased estimates of the necessary allowed rates of return in the presence of such regulatory risks. The book uses the new theory of regulatory risk to understand recent developments in the risk of natural gas pipelines and other regulated...

Automatic transformation of a sequential program into a parallel form is a subject that presents a great intellectual challenge and promises a great practical award. There is a tremendous investment in existing sequential programs, and scientists and engineers continue to write their application programs in sequential languages (primarily in Fortran). The demand for higher speedups increases. The job of a restructuring compiler is to discover the dependence structure and the characteristics of the given machine. Much attention has been focused on the Fortran do loop. This is where...
