This paper presents DITIS, a simulator for distributed and tiered file-based storage systems. In particular, DITIS can model system with up to three levels of tiers additional caches. Each tier cache be configured different number type media devices (e.g., HDD, SSD, NVRAM, DRAM), each their own performance characteristics. The utilizes the provided characteristics in fine-grained cost models (w...

This paper analyses the delivery of violence reduction and preparations for Serious Violence Duty in one region United Kingdom. Using Bath & O’ Moore’s 5c’s approach as an analytical framework, we explore response to Government Strategy (Home Office, April 2018.), Public Health approaches how prepared appears be implementation Duty. The evidence suggests development Reduction Units has led a tw...

OBJECTIVE The purpose of this study was to determine the number of thyroid nodule workups that could be eliminated and the number of malignant tumors that would be missed if the Society of Radiologists in Ultrasound (SRU) recommendations and the three-tiered system were applied to incidental thyroid nodules (ITN) detected at imaging. MATERIALS AND METHODS This retrospective study included ITN...

OBJECTIVE The objective of our study was to compare the cost-effectiveness of two approaches to using MRI for the evaluation of patients with hearing loss. MATERIALS AND METHODS We developed a decision tree to compare the cost-effectiveness of conventional MRI with that of a proposed two-tiered model in which an initial 3D T2-weighted imaging examination was used to determine the need for com...

The advances in hardware and wireless technologies have made mobile communication devices affordable by a vast user community. With the advent of rich multimedia and social networking content, an influx of myriads of applications, and Internet supported services, there is an increasing user demand for the Internet connectivity anywhere and anytime. Mobility management is thus a crucial requirem...

A large number of problems in computer vision can be modelled as energy minimization problems in a Markov Random Field (MRF) or Conditional Random Field (CRF) framework. Graph-cuts based α-expansion is a standard movemaking method to minimize the energy functions with submodular pairwise terms. However, certain problems require more complex pairwise terms where the α-expansion method is general...

Large-scale high-speed mass-storage systems account for a large part of the energy consumed at data centers. To conserve energy consumed by these storage systems, we propose a high-speed tiered-storage system with a poweraware proactive method of storage-tiering management that minimizes loss of performance, which we have called the energy-efficient High-speed Tiered-Storage system (eHiTS). eHi...
