A bstract We investigate the spontaneous breaking of subsystem symmetries directly in context continuum field theories by calculating correlation function charged operators. Our methods confirm lack symmetry some existing with symmetries, as had previously been established based on a careful analysis spectrum. present novel theory constructions that do exhibit whenever allowed general principle...

bin(k-1 ;n,p) = L n p xqn-x, the cumulative binomial function. k-1 ( ) x=o x C=the total of the cost of the subsystem itself plus the expected cost due to subsystem failure c1 = loss due to failure of the subsystem c3 =cost of a one module subsystem capable of full output c4 =cost of a module in a k-out-of-n:G (good) subsystem when k is fixed g(k) = the function relating cost of the subsystem t...

Renowned British archaeologist Colin Renfrew, in his seminal work The Emergence of Civilization: The Cyclades and the Aegean in the Third Millennium B.C., provides a theory for the development of complex cultures, which he calls the multiplier effect. According to Renfrew, innovations in one aspect, or subsystem, of culture, such as craft production, enhances and affects, through positive feedb...

This article is concerned with the engineering of societal information systems where technical components of a system software agents support the social network around which the system is centered. By software agent, we mean an autonomous software entity that can act in the system, perceive events and reason [1]. In information systems, software agents work on behalf of their owners in order to...

BACKGROUND Most Latin American health systems are comprised of public (PubS), social security (SSS) and private (PrS) subsystems. These subsystems coexist, causing health care fragmentation and population segmentation. OBJECTIVE To estimate the extent of subsystem cross-coverage in a geographically bounded population (Rosario city) and to compare the subsystems' performance on primary health ...

Impwtant aspects of mission operations for spacecraft (S/C) sent to explore outer space are: engineering subsystem performance analysis, characterization, and commanding, all involving a substantial amount of human resources and time. Recent efforts have brought about several productivity enhancement measures within the mission operations area that incluck the streamlining of the operations pro...
