We present Neumann-Neumann domain decomposition preconditioners for the solution of elliptic linear quadratic optimal control problems. The preconditioner is applied to the optimality system. A Schur complement formulation is derived that reformulates the original optimality system as a system in the state and adjoint variables restricted to the subdomain boundaries. The application of the Schu...

In the transport layer of the TCP/IP protocol suite, both TCP and UDP use internet checksum to protect headers and data. Internet checksum uses 1’s complement arithmetic to detect errors in the content delivered by the data-link layer. Both research and experience have shown that there are a wide variety of error sources which can not be detected by this lower layer. The error detecting perform...

We deal with the problem of preserving various versions of completeness in (< κ)–support iterations of forcing notions, generalizing the case “S–complete proper is preserved by CS iterations for a stationary costationary S ⊆ ω1”. We give applications to Uniformization and the Whitehead problem. In particular, for a strongly inaccessible cardinal κ and a stationary set S ⊆ κ with fat complement ...

The enhancement of dismissed military barracks is a big problem in Friuli Venezia Giulia region. The changed geo-politic conditions caused the abandonment of the numerous structures and the transfer of their property from State to Region and then to local municipalities. The regional government has not defined guidelines for their re-use and the work for the Patussi barracks, done to produce a ...

A health information system (HIS) is the intersection of between healthcare’s business process, and information systems to deliver better healthcare services. The nature of healthcare industry, which is highly influenced by economic, social, politic, and technological factors, has changed over time. This paper will address some important concepts of healthcare and related terminologies to provi...

a commonly desired ultimate foundation or ground is full unity, community, or consensus, which is often, if not typically, figured as lost or perhaps lacking, usually because of the intrusive presence of others seen as outsiders or polluters of the city or the body politic. One may, however, insist that such unity, community, or consensus is absent and that the sociopolitical problem is how to ...

A study was conducted to identify the most applicable area for youth to utilize the Personal Decision Aid (PDA). There are eight areas of decision making namely study, career, lifestyle, purchasing, friendship, politic, religion and marriage have been explored in this study. An online survey gathered from 80 respondents, age 18 to 24 years old to participate in the study. The main objectives of...

Text mining can be applied to many fields. One of the application is using text mining in digital newspaper to do politic sentiment analysis. In this paper sentiment analysis is applied to get information from digital news articles about its positive or negative sentiment regarding particular politician. This paper suggests a simple model to analyze digital newspaper sentiment polarity using na...
