Fault Diagnostics is one of the major requirements for assuring dependability of complex systems. In Systems level diagnostic procedures applied to computer interconnection networks, the processors diagnose each other and under certain conditions faulty processors can be identified. This paper simulates a system-level diagnosis algorithm for mesh with wraparound, topology to locate the faulty units...
In the paper, the structure of information security system was implemented and to evaluate its performance for the securely data transmit in the network. The Advanced Encryption Standard (AES) with Rijndael algorithm is divided into two major block encryption and decryption which is operated for the iteration and the symmetric password key block cryptography with 128, 196, and 256-bit. The Content...
The emerging demand for pervasive underwater monitoring and control systems has significantly stimulated the research on network protocols for underwater acoustic sensor networks. In the last few years, several solutions have been proposed for this kind of networks at all layers of the protocol stack. However, to achieve a thorough understanding of the performance of these protocols running simulations...
Computer network architects are concerned with reducing the execution time of applications while maintaining or reducing power consumption of the system. In order to demonstrate the advantages of photonic interconnection networks at the scale of high performance computer clusters and warehouse scale data centers, system level simulations are required. To achieve an appropriate level of accuracy both...
To integrate wind and solar energy in electric systems, new technologies, such as energy storage and demand response, have been proposed to increase system flexibility. Control approaches and market rules are being developed accordingly to better manage these resources in multiple time scales. Therefore, models and software tools capable of performing hourly scheduling, intra-hour dispatch, and automatic...
MANETS are used in a variety of applications today ranging from military communications networks to emergency response team networks. Their dynamic network topology is one of the greatest strength in employing MANETS, but invites many opportunities for cyber security attacks as computational power for these systems is always a viable resource. This paper documents a study where a MATLAB simulation...
Compressors are the most important component of multipliers. Multipliers themselves are important components that dictate the overall performance of arithmetic circuits. In this paper, a new 4–2 compressor architecture is proposed. This architecture uses Carry Generator Module (CGEN) which has been used for 5–2 and 7–2 compressors already. The proposed architecture is compared with the best architecture...
In this paper we present a cycle-accurate performance analysis method for real-time systems that incorporates the following phases: (a) profiling SW components at high accuracy, (b) modeling the obtained performance measurements in MARTE-compatible models, (c) generation, scheduling analysis and simulation of a system model, (d) analysis of the obtained performance metrics and (e) a subsequent architecture...
The application workloads in modern MPSoC-based embedded systems are becoming increasingly dynamic. Different applications concurrently execute and contend for resources in such systems which could cause serious changes in the intensity and nature of the workload demands over time. To cope with the dynamism of application workloads at run time and improve the efficiency of the underlying system architecture,...
The enterprise information networks (EIN) are forced to continuously update their service architectures to provide reliable network services. Employing distributed service architecture eases the addition of new applications/services to the existing EIN. However, the newly added applications/services may modify the existing EIN architecture (EINA) thereby necessitate the management scheme to be adaptable...
This paper proposes a novel modular architecture for Electrical Energy Storages (EESs), consisting of multiple series-connected cells. In contrast to state-of-the-art architectures, the presented approach significantly improves the energy utilization, safety, and availability of EESs. For this purpose, each cell is equipped with a circuit that enables an individual control within a homogeneous architecture...
Digital finite impulse response (FIR) filters play a very important role in digital signal processing (DSP) applications ranging from image and video processing to wireless communication. Digital FIR filter is primarily composed of multipliers, adders and delay elements. Several techniques have been reported in the open literature to implement digital FIR filters using Field Programmable Gate Array...
The objective of this study is to propose a low cost scalable architecture for embedded applications, using pools of personal computers for high performance storage, retrieval and processing of information through the study of traces and real solutions for companies operating in this niche market. By predictable intelligence (Box-Jenkins) it's possible to predict the future behavior of the application...
In 2010, JST/RISTEX in Japan started a new R&D program “Service Science, Solutions and Foundation Integrated Research Program”. The authors are engaged in a research project “Innovation for Service Space Communication by Voice Tweets in Nursing and Caring” selected by this program, and are developing a stress-free information assisting system based on smart voice messaging. By providing voice...
The single message ferry routing scheme works well in the small scale clustered DTNs (Delay/Disruption Tolerant Networks). However, as the increasing of the network scale, this scheme will lead to high delay. To solve this problem, a hierachical multiple ferries routing scheme (HMFRS) was proposed in this paper. In this scheme, a message ferry and a ferry access point are deployed in each DTN cluster,...
Advanced Distribution Automation (ADA) has become a topic of considerable interest in the electric power industry; moreover, for the development of ADA it is necessary to build new methodologies and computational tools to support the distribution networks (DN) simulation with Real Time Hardware in the Loop (RT-HIL) techniques, reducing the design and testing times at low cost. OpenDSS is a free powerful...
In the last decade, the microprocessor industry has undergone a dramatic change, ushering in the new era of multi-/manycore processors. As new designs incorporate increasing core counts, simulation technology has not matched pace, resulting in simulation times that increasingly dominate the design cycle. Complexities associated with the execution of code and communication between simulated cores has...
Cloud computing is becoming increasingly popular for the provisioning of computing resources, in particular, through scientific tools that perform modeling or simulations. Vehicular Ad-Hoc Networks (VANETs) are mobile ad hoc networks which are meant to support primarily safety warnings and to manage challenging conditions to improve our transportation experience. This is a challenging context where...
Using EtaOpt the detailed balance efficiency of the classic lattice matched InGaP/GaAs/Ge 3-junction cell and those of optimized band gap combinations for both monolithic and mechanical stacks are calculated under 500×AM1.5D illumination. The results are 48.7% (mono) and 59.2% (mech) for the classic and 59.6% (mono) and 60.3% (mech) for the optimized band gap structures. For these devices we calculated...
