. Summary In this paper, we propose a novel VOD server architecture and a dynamic prefetch buffer allocation algorithm based on popularity. This can drastically improve the maximum number of streams a drive can support, with a small startup latencies. The primary design goal is to guarantee glitch free operation for maximum number of users. Detailed simulation is carried out and compared with t...

Software defect prediction is an important aspect of preventive maintenance of a software. Many techniques have been employed to improve software quality through defect prediction. This paper introduces an approach of defect prediction through a machine learning algorithm, support vector machines (SVM), by using the code smells as the factor. Smell prediction model based on support vector machi...

With the emergence of Cloud Computing resources of physical machines have to be allocated to virtual machines (VMs) in an ondemand way. However, the efficient allocation of resources like memory, storage or bandwidth to a VM is not a trivial task. On the one hand, the Service Level Agreement (SLA) that defines QoS goals for arbitrary parameters between the Cloud provider and the customer should...

The economic and political realities of the 1990s forced managers to reverse long-standing organizational cultures in order to reduce costs and energy expenditures in their organisations. For instance, these can be achieved, with respect to maintenance, by replacing a reactive repair-focused attitude by a proactive reliability-focused culture. Thereby far less (i) human effort is expended and (...

Recently, efficient network resource management and qualityof-service (QoS) guarantee become more and more important for multimedia applications and services, especially when considering network delays. In this paper, an optimal bandwidth allocation scheme that achieves maximal utilization of the client buffer and minimal allocation of bandwidth for each client is introduced. The proposed schem...

In the competition to excel in Industrial 4.0 race, companies especially Semiconductor Industry, strive attain efficiency by removing process bottlenecks, improving productivity and increasing machine availability during operation. As so, this research was conducted analyze machine’s based on various preventive maintenance (PM) scheduling. A model developed WITNESS 14 Manufacturing Performance ...

We consider a joint rate and power control problem in a wireless data traffic relay network with fading channels. The optimization problem is formulated in terms of power and rate selection, and link transmission scheduling. The objective is to seek high aggregate utility of the relay node when taking into account buffer load management and power constraints. The optimal solution for a single t...

In this paper, we propose the concept of using query execution feedback for improving database buffer management. A query feedback model which adaptively quantifies the page fault characteristics of all query access patterns including sequential, looping and most importantly random, is defined. Based on this model, a load control and a marginal gain ratio buffer allocation scheme are developed....

Buffer allocation in WiMAX maximizes the throughput by achieving high link utilizationof system and minimizes the power consumption. In this paper, Traffic Based QoS Specific Adaptive Buffer Allocation in WiMAX networks is proposed to increase the system throughput by using an adaptive buffer allocation strategy. The buffer management block initially allocates buffer to the flow requests based ...
