a new efficient and practical method for the room-temperature reduction of aromatic nitro compounds employing feso4. 7h2o, nabh4, h3pw12o40 system in h2o under mild conditions is reported. the method is simple, inexpensive, easily scaled-up and applicable for the large scale preparation of different substituted anilines.

System chip, system on chip (SOC), system on silicon (SOS), there are many terms and many definitions that have arisen to describe the large chips that are emerging as we move further into the murky depths of the deep submicron era. Almost everyone has their own definition of system chip, which may explain why it is that almost everyone can claim to be designing system chips. However, as they b...

The cattle feedlot affords an ideal habitat for large concentrations of birds. Several species are p r i m a r i l y involved in feed depredations and contamination. The development of an integrated systems approach to control involves the interaction of human attitude, cultural control practices and a p p l i c a t i o n of b i r d damage control techniques, each of which is a dynamic system i...

This paper presents new results achieved with ESPRO, a software system for generating VLSI layouts. Its main advantages are minimal hardware requirements and its independence of programming languages, hardware platforms, and fabrication processes. It is thus designed for evaluation of new P&R heuristics in algorithm development and universitary backgrounds.

cell formation problem mainly address how machines should be grouped and parts be processed in cells. in dynamic environments, product mix and demand change in each period of the planning horizon. incorporating such assumption in the model increases flexibility of the system to meet customer’s requirements. in this model, to ensure the reliability of the system in presence of unreliable machine...

This paper investigates the problem of decentralized model reference adaptive control (MRAC) for a class of large scale systems with time varying delays in interconnected terms and state and input delays. The upper bounds of the interconnection terms are considered to be unknown. Time varying delays in the nonlinear interconnection terms are bounded and nonnegative continuous functions and thei...
