sound-based security systems use a speaker to ring, or vibrate, for a few seconds when any noise is detected outside the door. these systems are essentially intrusion detection systems. they send a signal to a monitoring station when there are any unusual noises. not only can these systems tell someone is trying to get in, but they can also transmit alarm signals to other sensors in the house to wake up others. with the help of electronics, computers can decode the signal and notify people when there’s a threat. systems can be placed along windows and doors and can be easily hidden with wall-mounted enclosures.

a computer engineer and expert on national security issues, who oversees the development of a program to counter terrorism. the software analyzes digital communications that flow between the national security agency (nsa) and computer systems around the world to stop or, if necessary, detect the malicious use of those computers. thus the program is intended to sniff out computer viruses, spammers, hacking, and other illicit activities.

a research project at stanford university seeks to develop an intelligent computer system with the ability to write sophisticated programs. the “emergent computer” project is aimed at creating a machine that is more intelligent than the most intelligent man ever (the emergence of life), it is capable of organizing knowledge, creating new knowledge, and even creating new kinds of intelligence. the basis of emergent computing is that the computational model of a computer is no longer the turing machine, but a “reconfigurable computing machine” that has not been designed to perform a specific function. the idea is to design programs that can generate emergent behavior. all of this is the future of a computing paradigm. you have to start with an architecture that is not preconceived, a system that is not predetermined.

an adaptive compiler with binary domain knowledge and linguistic rules that is illustrated for an underdeveloped, but important, domain of content-based editing. the compiler is tailored to handle the binary structures of a text-based language as well as the intelligence embodied in the user’s domain knowledge for the purpose of editing. first the parser is adapted to handle a new binary language as well as, more importantly, a set of user rules for editing documents which have structure. these are then used to guide the parsing. once parsing is completed, the parser is refactored to combine it with the context for the editing rules and the document structure. in an important feature, the parser and the editing rules and the document structure work together, so that when the user makes a change, the parser is able to inform the knowledge of the rules and the structure which is being edited, and can elicit more appropriate editing rules. a compiler architecture for developing compilers that make use of the semantics of a logical language. the architecture uses a framework for developing semantic predicates for logical languages, and has been implemented for definite and deontic action language. an implementation is described for a definite action language compiler for the mathematica programming language. this is a very early stage in compiler development. this paper describes an implementation of a domain-independent, compiler-integrated, domain-based dynamic type checking program. the program computes an input list of type annotations in parallel. it is described and its semantics discussed. its use and effectiveness illustrated with code examples. 5ec8ef588bأهلا-بالعالم/
