Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...

We present a performance-based methodology for designing a high-bandwidth radar application on commodity platforms. Unlike many real-time systems, our approach works for commodity processors running commodity operating systems. Our technique is innovative because it uses stochastic models of the processing time at each step in the process to allow for the variabilities of running on a non-realt...

Visual sensor networks (VSNs) consist of image sensors, embedded processors and wireless transceivers which are powered by batteries. Since the energy and bandwidth resources are limited, setting up a tracking system in VSNs is a challenging problem. In this paper, we present a framework for human tracking in VSNs. The traditional approach of sending compressed images to a central node has cert...

coarse tuning of an MVS system by analyzing it into its software and hardware components and increasing their eficiency successively. The method involves adjustments to swapping, the inputoutput load, the CPU load, main storage, and the system resources manager. Also discussed are performance measures necessary to characterize a system, tools to tune a system, and various aspects of data gather...

background : the aim of the present study was to assess the auditory working memory span of children with (central) auditory processing disorders (c) apd aged 8 to 10 years and to compare the results with normal ones. methods: twenty five children with (central) auditory processing disorders (8-10 years) and 75 normal children (8-10 years) from both genders participated in this comparative stud...

ION OF HETEROGENEITY YARN creates containers on each machine based on the total memory and the number of CPU cores. If there are two machines with different memory size, then they will have different numbers of containers. In other words, unlike Hadoop, YARN takes resource heterogeneity into account, in the case of memory. However, YARN still does not consider heterogeneity in other resource ch...

The spatial join operation is both one of the most important and expensive operations in Geographic Database Management Systems (GDBMS). This paper presents a set of rules to optimize the performance of the filtering step of spatial joins operations. First, a set of expressions to predict the number of I/O operations and CPU performance is presented. The rules are based on expressions to predic...

Currently, the IETF RSerPool WG is standardizing a generic protocol framework for server redundancy and session failover: Reliable Server Pooling (RSerPool). An important property of RSerPool is its lightweight architecture: server pool and session management can be realized with small CPU power and memory requirements. That is, RSerPool-based services can also be managed and provided by embedd...
