The benefits associated with separation of concerns are well established. Aspect-Orientation is a methodology that aims at separating components and aspects from the early stages of the software life cycle, and using techniques to combining them together at the implementation phase. Componentbased programming systems have shown themselves to be a natural way of constructing extensible software. Well-defined interfaces, encapsulation, late binding and polymorphism promote extensibility, yet despite this synergy, components have not been widely employed at the systems level. This is primarily due to the failure of existing component technologies to provide the protection and performance required of systems software. In this paper we identify the requirements for a component system to support extensions, and describe an extensibility and adaptability in the design of system software. We discuss an aspect-oriented framework that can simplify system design by expressing it at a higher level of abstraction. Our work concentrates on how to achieve a higher separation of aspects, components, and layers from each other. Our goal is to achieve a better design model for system software in terms of extensibility, reuse and adaptability.

This paper describes the principles underlying an efficient implementation of a lazy functional language, compiling to code for ordinary computers. It is based on combinator-like graph reduction: the user defined functions are used as rewrite rules in the graph. Each function is compiled into an instruction sequence for an abstract graph reduction machine, called the G-machine, the code reduces a function application graph to its value. The G-machine instructions are then translated into target code. Speed improvements by almost two orders of magnitude over previous lazy evaluators have been measured;we provide some performance figures.

＜正＞Parallel Kinematic Machines （PKM）, i.e. machines based on parallel structures, have become a more and more promising alternative to conventional serial machines in the field of handling units, robots and machine tools. Just replacing the serial type with the parallel one is not recommended here. To find a technical as well as economical basis of decision it is necessary to define characteristic functions and assign indices to create structural performance criteria of the mechanical system. Characteristic functions may become thereafter elements of a global goal or cost function in a following optimization procedure.
