Active hood lift system has been developed to get more spaces for decreasing the head injury during pedestrian impact. This system is composed of detecting sensor, ECU where the algorithm is embedded and the pyro-type actuators which raise the hood. By this system, the rear part of the hood is raised up to approximately 120mm. The test results of system operation are introduced for each three t...

Deficit Round Robin (DRR) is a scheduling algorithm which provides fair queuing at O(1) complexity. However, due to its round robin structure, its latency properties are not adequate for latency-critical applications, such as voice. For this reason, router manufacturers implement variants of the DRR algorithm which guarantee lower latencies to one (or a subset of) queue(s). In this paper we eva...

Bluetooth is a wireless access technology where polling is used to share bandwidth among the nodes. In this paper, a new polling scheme for intra-piconet scheduling in Bluetooth piconets, Priority Gated Round Robin, is proposed. The performance of this algorithm is analyzed via simulation in different cases such as different Segmentation And Reassembly algorithms, different packet sizes, and va...

BACKGROUND AND PURPOSE Early deterioration can occur after acute stroke for a variety of reasons. We describe a hemodynamic steal and associated neurological deterioration, the reversed Robin Hood syndrome (RRHS). We aimed to investigate the frequency and factors associated with RRHS. METHODS Consecutive patients with acute cerebral ischemia underwent serial National Institutes of Health Stro...

background and objective : a considerable amount of sulfur hexafluoride is applied to evaluate the performance of each laboratory hood according to ashrae–110-95 method. sf 6 is extremely hostile to environment and expensive. in present work, the possibility of conducting this method of hood performance test with less volume of sf 6 was investigated. material and methods : the performance of a ...

The main objective of this paper is to develop a new approach for round robin scheduling which help to improve the CPU efficiency in real time and time sharing operating system. There are many algorithms available for CPU scheduling. But we cannot implemented in real time operating system because of high context switch rates, large waiting time, large response time, large trn around time and le...
