The purpose of the thesis is to determine whether Java, a programming language that evolved out of a research project by Sun Microsystems in 1990, is suitable for solving large sparse linear systems using direct methods. That is, can performance comparable to the language traditionally used for sparse matrix computation, Fortran, be achieved by a Java implementation. Performance evaluation criteria include execution speed and memory requirements. A secondary criterion is ease of development. Many attractive features, unique to the Java programming language, make it desirable for use in sparse matrix computation and provide the motivation for the thesis. The 'write once, run anywhere' proposition, coupled with nearly-ubiquitous Java support, alleviates the need to re-write programs in the event of hardware change. Features such as garbage collection (automatic recycling of memory) and array-index bounds checking make Java programs more robust than those written in Fortran. Java has garnered a poor reputation as a high-performance computing platform, largely attributable to poor performance relative to Fortran in its early years. It is now a consensus among researchers that the Java language itself is not the problem, but rather its implementation. As such, improving compiler technology for numerical codes is critical to achieving high performance in numerical Java applications. Preliminary work involved converting SPARSPAK, a collection of Fortran 90 subroutines for solving large sparse systems of linear equations and least squares problems developed by Dr. Alan George, into Java (J-SPARSPAK). It is well known that the majority of the solution process is spent in the numeric factorization phase. Initial benchmarks showed Java performing, on average, 3. 6 times slower than Fortran for this critical phase. We detail how we improved Java performance to within a factor of two of Fortran.

Šiame darbe mes įvardinome J2EE projekto kūrimo problematiką. Ištyrėme įrankį Appfuse, kuris yra skirtas programuotojo darbui palengvinti. Appfuse atlieka J2EE internetinio projekto infrastruktūros generavimą, kompiliavimą, veiksmų automatizavimą ir kitas naudingas užduotis. Šį įrankį panaudojome Bendrabučių informacinei sistemai sukurti ir taip įsitikinti Appfuse nauda. Projektas buvo pradėtas greitai ir kodo rėmai leido programuoti šiuolaikiškai pagal trijų lygių architektūros schemą. Nereikėjo gilintis į sudėtingų technologijų, tokių kaip Spring ir Hibernate integravimą. Dokumente aprašėme naudojamos priemonės suteikiamus privalumus ir panaudojimą tyrimą. / In this paper we tried to look into J2EE project start and development problem. There are so many development tools to be used in project that causes the complexity. The used tools must be configured to communicate with each other and has different style of configuration. Build, testing, deployment tools must be implemented and m1anaged for every J2EE project. We analyze the solution Appfuse, which eliminates the problems mentioned above. Appfuse is open source project and program, which help fast and efficient software development. The proofs of concepts were illustrated by creating the Information System for Dormitories.

Domestic space is a primary site for cultural reproduction. When the inhabitants intensively interact with domestic space, the house receives its cultural significance. This thesis aims to understand how, through practices, meanings are embodied in the spatial formation of the Javanese house, and how these meanings in return affect the spatiality of certain practices. The subject of these observations are four houses of considerably different scales and forms, which range from a simple single-structure house to the elaborate Sultan's palace. The domestic activities observed encompass three types of activities: daily life, ritual celebrations, and theatrical performances. My study is based on direct observation and involvement in such activities, personal interviews, and the published works of other scholars. The central arguments of the thesis are that the two-part division of the house is legible in all these examples and that this front-rear division has a dynamic relationship with established cultural practices.

This dissertation surveys the historical and intellectual development of the Ṭariqa Qadiriyya Naqshbandiyya (TQN), the amalgamated Sufi order founded in Indonesia by Shaykh Aḥmad Khaṭib Sambas (d.1875). After a brief recapitulation of the progress of Sufi orders in and beyond Java, it looks at the life and activities of Shaykh Sambas, and analyzes in particular his work Fatḥ al-`Arifin, situating it against the Qadiriyya and Naqshbandiyya sources that inspired it. The focus then switches to the transmission of the TQN doctrines by Sambas's disciples, especially `Abd al-Karim Banten (b. 1840), and the gradual dispersal of the order throughout the archipelago, which resulted in the formation of branches that maintained separate existences but largely similar teachings. This leads into a discussion of the TQN of Suryalaya (west Java), one of the most significant branches of the TQN in present-day Indonesia, although some attention is given also to other TQN centers, such as Mranggen and Rejoso in central and east Java, and to the writings of shaykhs in these regions. Although the main teachings of the ṭariqa have remained constant, local shaykhs have some cases developed in response to local circumstances; thus we find in the case of the TQN of Suryalaya, that its shaykh, Kiyai Haji Shohibulwafa Tajul `Arifin (better known as Abah Anom) has concentrated on dhikr as an educational tool and as a means towards healing young drug addicts and victims of other mental illnesses. The spiritual and social benefits of TQN teachings came across clearly in Abah Anom's work Miftaḥ al-Ṣudur, which contains his views on a variety of mystical subjects, and which is analyzed in the final chapter. There we find that Abah Anom preserves TQN teachings intact while stressing some of its aspects and de-emphasizing others that preoccupied the order's founder, such as the doctrine of muraqaba.
