Many-core processors exhibit hundreds to thousands of cores, which can execute lots of multi-threaded tasks in parallel. Restrictive power dissipation capacity of a many-core prevents all its executing tasks from operating at their peak performance together. Furthermore, the ability of a task to exploit part of the power budget allocated to it depends upon its current execution phase. This mandates...
Solar photovoltaics (PV), one of the most promising and rapidly developing renewable energy technologies, has evolved towards becoming a main renewable electricity source. It is termed variable energy resources since solar irradiance is intermittent in nature. This variability is a critical factor when predicting the available energy of solar sources. Capital and operational costs associated with...
In today's cloud computing platforms, more and more users are now working or collaborating in multi-cloud environment, in which collaborators, clouds, computing nodes may belong to different institutions or organizations. Those different organizations might have their own policies. Security is still a big concern in cloud computing. To help cloud vendors and customers to detect and prevent from being...
In the last two decades, the increase in the amount of information available online have resulted in an information overload problem making it very complex for users to get the useful information they require within time. A recommender system helps customer to make useful decisions about products they wants to purchase thus providing better customer satisfaction which is vital in online environments...
This paper describes a reliable methodology for radar cross section (RCS) measurement of complex small and large targets in the W band. The backscattering behavior of a small car model was measured in an anechoic chamber along with various automotive related targets in a wide gymnasium. Experimental performance in the anechoic chamber is compared to the simulation results. Our simulation model is...
Current DRAM based memory systems face the scalability challenges in terms of storage density, power, and cost. Hybrid memory architecture composed of emerging Non-Volatile Memory (NVM) and DRAM is a promising approach to large-capacity and energy-efficient main memory. However, hybrid memory systems pose a new challenge to on-chip cache management due to the asymmetrical penalty of memory access...
The distance metric learning is the method to learn the distance metric from training data considering its statistical characteristics under the arbitrary constraints. To obtain the desirable distance metric, the optimization problem is solved. Most of the distance metric learning methods aim to gain the global optimal metric matrix. However there is a possibility that the global metric matrix cannot...
In recent years, social media such as Twitter have encountered a significant growth because of the ceaseless increase in the volume of contents and the number of users. The level of influence among social media users is significantly different from one user to the other; and as such, it has become more vital to find the most influential users on social media. There are lots of mysteries about behaviours...
In this paper, we analyze the temporal performance of multi-robot system which are performing a foraging object task. The coordination between different robotic agents was inspired by the ant colony optimization algorithms (ACO). The objective was to prospect about parameters influence on foraging objects time. In this work, we consider three possible influencing parameters including robotic group...
The evaluation of dependability or performance of general systems usually relies on the assistance of stochastic modeling and simulation tools. Those software packages enables the creation of models and computation of metrics quickly and accurately. This paper introduces the Mercury tool, which is an integrated software that enables creating and evaluating Reliability Block Diagrams, Stochastic Petri...
Detection of corner is the most essential process in a large number of computer vision and image processing applications. We have mentioned a number of popular contour-based corner detectors in our paper. Among all these detectors chord to triangular arm angle (CTAA) has been demonstrated as the most dominant corner detector in terms of average repeatability. We introduce a new effective method to...
Due to the massive explosion of social networking and content sharing, it is becoming challenging to transmit a huge amount of multimedia content over wireless mobile networks. The existing paradigm of mobile multimedia sharing has yet to effectively address the energy and bandwidth limitations of wireless devices. Content-Centric Networking (CCN) has been proposed as a possible way to drive the current...
Predicting the amount of resources available to system's users has become a task of interest to services providers even with the advent of elastic cloud computing, because the number of resources is finite despite being virtually infinite on the customer view. This paper proposes a model to evaluate node's capacity in a cloud computing environment based on the amount of available hardware resources...
We propose a remapping algorithm to tolerate the failures of Processing Elements (PEs) on Multiprocessor System-on-Chip. A new graph modeling is proposed to precisely define the increase of communication cost among PEs after remapping. Our method can be used not only to repair faults but also to improve the communication cost of given initial mapping results. Experimental results show that under multiple...
Driver evaluation and performance monitoring is crucial for safety and risk assessment. This paper proposes a novel algorithm for evaluating driver performance using vehicle state data. This indirect method of evaluation has the advantage of being unobtrusive and cheap as it uses only the easily accessible real time vehicle data. The proposed algorithm can eliminate subjectivity and automate the evaluation...
In this paper, we propose a novel controller design technique to track a reference trajectory for a class of hybrid systems having state-triggered jumps. The idea is, by gluing start and end points of jumps in the state space, to change the domain into another domain where the state jumps disappear. After gluing, the hybrid systems can be considered as continuous or piecewise continuous dynamical...
Transformation of occurred rainfall into runoff generated within a catchment is a complex natural phenomenon that passes through various inter-related processes and influenced by many topographic, geographic, geologic and sociologic factors. To develop a model that can reliably imbibe the complex Rainfall-Runoff interaction, two different approaches namely, conventional regression and Artificial Neural...
Because of the volatility of memory, nodes in in-memory storage system crashing down would lead to data lost. One solution to this problem is backing data up. However, if we backup data to a node which is about to fail down, the data should be recopied again. That would lead to a large amount of backup data, and in turn reduce the system reliability. We first establish a correlated failure model with...
An opportunistic network (OPPNET) is an alternative to a mobile ad-hoc network (MANET) in which no complete path is needed. If a complete path is unavailable, the source node sends the message through relay nodes until the message arrives at its destination. Friendship-Based Routing (FBR) is routing scheme for an OPPNET which uses the inter-contact time of each node to find a good relay node. Unfortunately,...
Almost all e-commerce websites generates recommendations for their users but most of them are irrelevant. Collaborative filtering is one of the most widely used recommendation generation technique by e-commerce websites. Collaborative filtering generates recommendations for the target user from the collaboration of the other users who have the similar interest derived from their ratings. With the...
