Modern high performance disk systems make extensive use of non-volatile RAM (NVRAM) write caches. A single-copy NVRAM cache creates a single point of failure while a dual-copy NVRAM cache is very expensive because of the high cost of NVRAM. This paper presents a new cache architecture called RAPID-Cache for Redundant, Asymmetrically Parallel, and Inexpensive Disk Cache. A typical RAPID-Cache co...
The secondary cone crusher's shields at Sarcheshmeh Copper Complex of Iran are made of Hadfield steel with a nominal composition of Fe-1.3 % C-12 % Mn. They have a cut-off in the shape of a cone with an upper end diameter of 80cm and an approximate lower end diameter of 200 cm whose main problem is an unexpected early failure under normal working condition. In this paper, the results of metallo...
Background: Medical malpractice is one of the most important legal issues in medicine committed more or less by physicians. The medical staff has inadequate or deficient awareness of medical errors and their importance. Therefore, this study investigated the frequency of medical malpractices/errors resulting in death in files referred to the Iranian Legal Medicine Organization. Methods: The st...
despite the extensive deployment of multi-core architectures in the past few years, the design and optimization of each single processing core is still a fresh field in computing .on the other hand, having a design procedure (used to solve the problems related to the design of a single processing core )makes it possible to apply the proposed solutions to specific-purpose processing cores .the i...
A storage tank, which is used to store oil, important and high-risk equipment that requires attention its safety aspects. As a preventive measure, the government inspections of all tanks, either on regular basis (every four years) or based risk assessment. This study aims create an inspection plan for tanks at oil refinery using risk-based (RBI) method. The RBI method in this adopts API RP 581,...
Caching data files directly on mobile user devices combined with device-to-device (D2D) communications has recently been suggested to improve the capacity of wireless networks. We investigate the performance of regenerating codes in terms of the total energy consumption of a cellular network. We show that regenerating codes can offer large performance gains. It turns out that using redundancy a...
This research was conducted to investigate the factors contributing to thefailure in the forestry and rangeland by-product cooperative companies in Lorestanprovince, Iran. A descriptive-correlative research design was used. The statisticalpopulations were 1100 people divided into two groups of experts from natural resourceagency in Lorestan province and members of cooperative companies. The sam...
In order to reduce the overhead of synchronizing operations of shared memory multiprocessors, this paper proposes a mechanism, named specMEM, to execute memory accesses following a synchronizing operation speculatively before the completion of the synchronization is con rmed. A unique feature of our mechanism is that the detection of speculation failure and the restoration of computational stat...
Background: Statistics have shown that the rate of technical failure in peritoneal dialysis (PD) is greater than hemodialysis. In this regard, the present study is aimed to determine the prevalence and risks factors of technique failure of PD in Iranian children using the country’s computerized PD data registry system. Materials and Methods: </st...
Background: Reduction of errors is necessary to improve the quality of healthcare, promoting communication between the hospital staff and patients, and decreasing the patient's complaints in hospitals. Due to the high probability of error in the operating room (OR), this study aimed to detect the potential errors in the OR of Nemazee hospital using FMEA. Materials and Methods: This study was a...
