Using the Gross Domestic Product (GDP)as a measurement of aggregate economic activity is typical. Its cycles are used as an indicator of boom or recession in the economy. Economists and business people are interested in describing and predicting future values of such indicators.However, due to its intrinsic difficulty and non-linear characters, along with many unknown and random events, it is n...

Scheme includes a simple yet powerful macro mechanism. Using macros, programmers can easily extend the language with new kinds of expressions and definitions, thus abstracting over recurring syntactic patterns. As with every other powerful language mechanism, programmers can also easily misuse macros and, to this day, broken macro definitions or macro uses pose complex debugging problems to pro...

BACKGROUND AND OBJECTIVE The USE IT-model integrates theories about adoption and diffusion of innovations and is suitable to predict and evaluate the success of an information system from a user's perspective. The USE IT-model consists of four determinants: relevance, requirements, resources and resistance, which are measured at the macro-level (organizational), and at the micro-level (individu...

Macro-sieve electrodes were implanted in the sciatic nerve of five adult male Lewis rats following spinal cord injury to assess the ability of the macro-sieve electrode to interface regenerated peripheral nerve fibers post-spinal cord injury. Each spinal cord injury was performed via right lateral hemisection of the cord at the T9-10 site. Five months post-implantation, the ability of the macro...

there has been extensive debate in iran over recent years about appropriate exchange regime. some are fixed exchange rate pros, some advocate the managed floating regime, and others believe in pegging the exchange. rate in which nominal exchange rate is annually adjusted to the there are certain provisions embodied in the structure of the basic model, which may identify it as a generally useful...

This paper puts forward a method of building a macro model of operational amplifier. And then it describes the way on how to use the Verilog-AMS language with the Cadence Virtuoso AMS simulator as a simulation tool in the behavior level. In order to verify the correctness of the behavior descriptions, the paper simulates the described op-amp in a basic integral operation. The result shows the m...
