The main objective of a self healing scheme is to share and secure the information of any system at the same time. “Self-healing” techniques ultimately are dependable computing techniques. Specifically self-healing systems have to think for itself without human input, able to boot up backup systems. However, sharing and protection are two contradictory goals. Protection programs may be complete...

This paper presents a novel architecture of a single system image built on cluster system, named Glosim. This system orientates to cluster system middleware, which provides global system image support. It not only supports global IPC objects including message queue, semaphore and shared memory, but also presents a new concept of global working process and provides it SSI support smoothly and tr...

Predictability is of paramount concern for hard real-time systems. In one approach to predictability, every aspect of a real-time system and every primitive provided by the underlying operating system must be bounded and predictable in order to achieve overall predictability. In this paper, we describe several concurrency control synchronization mechanisms developed for a next generation multip...

Much work has been undertaken on investigating the use of semaphore primitives in concurrent programming languages. It has been shown that semaphores are adequate for expressing many forms of concurrency control, including the enforcement of communication protocols, and mutual exclusion protocols on shared resources. In this paper we present a formal language for real-time distributed programs ...

Sering dijumpai di komunikasi antar kapal dan dikepramukaan penggunaan bendera semaphore untuk media jarak jauh. Pembelajaran umumnya dilakukan secara manual menggunakan pendeteksian dengan citra digital. Namun keduanya memiliki keterbatasan yaitu ketersediaan tenaga ahli/tutor permasalahan pencahayaan. Mengingat pentingnya jauh maka ahli memerlukan guidance system yang dapat menilai gerakan la...

In 20th‐century Northeast Brazilian representations of the landscape estuarine Atlantic coast we find a re‐calibration perspective that is foreshortened, embodied, and muddied. These works produce counter‐hegemonic political aesthetics nature unsettles fixities colonial ways seeing space, nature, territory. As landscapes, they re‐configure relationship between space perception, aesthetics.

The reader-writer-problem is a standard problem in concurrent programming. A resource is shared by several processes which need either inclusive reading or exclusive writing access. The known solutions to this problem typically involve a number of global counters and queues. Here a very simple algorithm is presented which needs only two semaphores for synchronisation and no other global objects...

A perennial problem in recovering 3-D models from images is repeated structures common in modern cities. The problem can be traced to the feature matcher which needs to match less distinctive features (permitting wide-baselines and avoiding broken sequences), while simultaneously avoiding incorrect matching of ambiguous repeated features. To meet this need, we develop RepMatch, an epipolar guid...

A family of four mutual exclusion algorithms is presented. Its members vary from a simple three-bit linear wait mutual exclusion to the four-bit first-come firstserved algorithm immune to various faults. The algorithms are based on a scheme similar to the Morris’s solution of the mutual exclusion with three weak semaphores. The presented algorithms compare favorably with equivalent published mu...
