With cloud computing, the efficient management of resources is of great importance as an increased utilization of the available resources can result in higher scalability and significant energy and cost reductions. Experimental validation of novel resource management strategies is costly and time consuming, and often requires in-depth knowledge of and control over the underlying cloud platform. As...
Dual Tone Multi Frequency signal detection is an important to developing for telecommunication equipment. "This is a standard where keystrokes from the telephone keypad are translated into dual tone signals over the audio link". FPGA has gains very popularity in recent years due to their reprogram ability and flexibility. This paper presents a new type of ZYBO Board ZYNQ 7000 series FPGA...
In this work, we focus on the problem of virtual machines (VMs) placement in geographically distributed data centers, where tenants may require a set of networking VMs. The aim of the present work is to plan and optimize the placement of tenant's VMs in a distributed Cloud environment while considering location and system performance constraints. Thus, we propose ILP formulations which have as objective...
Predicting the application behavior such as its resource utilization in a new hardware machine is becoming an urgent issue as the increasing number of servers with various configurations show up in data centers and clouds. Current two categories of approaches, the test bed evaluation based and the software simulation based methods, both have certain shortcomings. While the test bed evaluation based...
This paper presents a novel multi-bit and multi-image steganography system using adaptive embedding algorithms with minimum error. These embedding algorithms can embed multi-bit (k-bit, k>=1) secret data into cover data only introduce minimum embedding errors which are restricted to-(2^(i-1)-1)*2^(i-k) ~ +(2^(i-1)-1)*2^(i-k) according to the embedding location i. To achieve the goal of minimum...
Future systems will have to support multiple and concurrent dynamic compute-intensive applications, while respecting real-time and energy consumption constraints. With the increase in the design complexity of MPSoC architectures that must support these constraints, flexible and accurate simulators become a necessity for exploring the vast design space solutions. In this paper, we present an asymmetric...
Communication receivers supporting multiple standards and modulation techniques are thirst of the time. Military has initiated technology like Software Defined Radio (SDR) which supports various network types and demodulation techniques. To test such devices all types of modulators which can source all possible test inputs for such receivers are needed. Instead of using off-the-shelf but costly instruments...
In attempts to exploit a diverse set of resources in grids efficiently, numerous assays in resource management, particularly scheduling, have been made. The primary objective of these efforts is the minimization of application completion time; however, they tend to achieve this objective at the expense of redundant resource usage. This paper investigates the problem of scheduling workflow applications...
