Infrastructure development in this era has developed rapidly. Excavators are generally used to dredge rivers, dismantle roads, or demolish buildings. One of the most important components an excavator is bucket teeth. Bucket teeth have two characteristics, namely maximum performance and wear life. Therefore, author interested discussing one problems that exist optimizing design already on market...

Basalt and its reinforcement fibres are highly corrosion resistant, which extends life lowers production costs while improving shear flexural strength. Despite the fact that previous study has only concentrated on mechanical properties of composite fibres. A brief examination was conducted to better understand reinforced concrete constructions made from basalt their reinforcements. This examine...

It is critical to provide high performance for scientific programs running on a Chip MultiProcessor (CMP). A CMP architecture often has a shared L2 cache and lower storage hierarchy. The shared L2 cache can reduce the number of cache misses if the data are commonly shared by several threads, but it can also lead to performance degradation due to resource contention. Sometimes running threads on...

Dynamic partitioning of shared caches has been proposed to improve performance of traditional eviction policies in modern multithreaded architectures. All existing Dynamic Cache Partitioning (DCP) algorithms work on the number of misses caused by each thread and treat all misses equally. However, it has been shown that cache misses cause different impact in performance depending on their distri...

Mass screening for cystic fibrosis by a trypsin assay of stool dried on filter paper was evaluated in 20 000 5-day-old babies. Sweat tests were required in only 7 babies. Three of them had cystic fibrosis. The test gave a false-negative result in at least 2 babies, but each had normal pancreatic function. This is not an ideal screening test for cystic fibrosis, as it misses cases with normal pa...

In this paper we introduce a classification of misses and of components of the data traffic in shared-memory multiprocessors based on inter-processor communication. We consider protocols with invalidations, updates and prefetches in systems with infinite and finite caches. We identify the set of essential misses and the essential traffic, i.e., the smallest set of misses and the smallest amount...

Aluminum alloys are the most attractive solutions for many industries including aerospace, marine, and other transportation sectors where lightweight construction is required. Friction Crush Welding (FCW) a new material joining process that simultaneously creates mechanical lock metallurgical seal at interface between similar dissimilar materials. In this research work presents development of n...

The inverse stereographic projection (ISP), or equivalently, bilinear transformation, is a method to produce circular distribution based on an existing linear model. By the genesis of ISP method, many important models have been provided by researchers. In this study, we propose new symmetric unimodal/bimodal rotated considering hyperbolic secant as baseline distribution. Rotation means that fix...

The increasing number of threads inside the cores of a multicore processor, and competitive access to the shared cache memory, become the main reasons for an increased number of competitive cache misses and performance decline. Inevitably, the development of modern processor architectures leads to an increased number of cache misses. In this paper, we make an attempt to implement a technique fo...
