This paper proposes the use of a new approach, i.e., ‘Self Assessing Processes’ approach in high performance computing (HPC) applications in which all processes identify the section of data to be computed using them. After the successful completion of these computations, each process employs a Message Passing Interface (MPI) I/O to write the results to a file in parallel. This eliminates idle time...
It was investigational on the basis of the considered existent methods, that the task of exposure of optimal recovery scheme answers the mathematical task of BIB-schemes. In the process of work the recovery scheme was worked out on the basis of BIB-schemes, which works for the greater number of the damaged computers, what other existent charts. Recovery scheme of distributed system that guarantees...
The papers present an analysis of the advantages and disadvantages of application joined wing layout for unmanned aerial vehicle. Synthesis of optimal layout by criteria for aerodynamic efficiency, flight duration and weight of the structure are given in the article
Multiple Self-Organizing Networks (SON) functions have been deveoped towards the SON promise of automating cellular network operations. Meanwhile, advancing SON towards Cognitive Cellular Networks requires the (SON) Functions (SFs) to autonomously learn the required optimal configurations. Since the SFs adjust the same or related network parameters, conflicts are bound to occur. Mechanisms that are...
A precise planning and operation of the power system requires an accurate load model that account for the load stochastic nature. In addition, the probabilistic power flow is a vital tool for power system engineers. Hence, this paper presents a novel probabilistic load model that models the load with an average load curve in addition to a probabilistic error around this average value. The goodness...
Data stream is generated everywhere with ever increasing speed. There is a need for efficient stream processing systems and optimal algorithms to mine all items of these streams to accurately predict the knowledge in limited time. In the existing approaches, there are some limitations like one-pass, sampling and load shedding on processing the streams which trade-off in accuracy. There are some approaches...
Computational grids comprise heterogeneous collections of resources. Resources have varying and unreliable performance because of network bandwidth, system load, network failure, connection between grid resources, tasks running on resources and various other factors. To predict when a new resource will be added or removed is quite difficult. A resource that was available at certain time might not...
The generation of Compact Thermal Models (CTMs) for electronics packages with simulation tools has long been a task for thermal engineers. One of the challenges traditionally associated with this task is the engineering effort required to reliably create a high quality detailed simulation model of a package family and any design variants in a consistent manner. Implementation of an automated methodology...
This section of the volume contains the proceedings of the 3M4SE 2014 workshop, held on September 1-2, 2014, in Ulm, Germany, in conjunction with the 18th IEEE International EDOC Conference on Enterprise Computing, EDOC 2014.
Cloud Computing researches involve a tremendous amount of entities such as users, applications, and virtual machines. Due to the limited access and often variable availability of such resources, researchers have their prototypes tested against the simulation environments, opposed to the real cloud environments. Existing cloud simulation environments such as CloudSim and EmuSim are executed sequentially,...
A direct sensor to actuator communication model for Ethernet-based Networked Control Systems (NCSs) is presented in this paper. This model is compared to a previously introduced model including an in-loop controller node. OMNET simulations showed the success of the presented model in meeting system delay and strict zero packet loss (with no over-delayed packets) requirements. The model also showed...
New concepts like agent-based modelling are providing social scientists with new tools, more suited to their background than other simulation techniques. The success of this new trend will be strongly related to the existence of simulation tools capable of fulfilling the needs of these disciplines. Given the computational requirement of realistic agent-based models, high-performance computing infrastructure...
Due to the boom in trust research new Trust Frameworks are created within short time intervals providing specific solutions for different domains. But these frameworks miss a common understanding and shared description. Based on available categorizations and surveys we collected key components already identified within Trust Management and created a generally applicable meta-model, which aims at creating...
Within a list of available candidate services offering the same functions, users lean to select the less time consuming ones under the time sensitive situation. Considering the features of the process-aware services, this paper provides a novel consuming time duration computing method that shows high accuracy of performance description. After that a service selection mechanism is proposed to leverage...
As the IEEE 1516 standard for distribution simulation, High Level Architecture (HLA) framework does not solve the issues of scalability, dynamic load-balance and fault tolerance. HLA does not support federation migration, which would balance the system workload on heterogeneous distributed resources and consequently improve simulation's performance either. In this paper, a Grid based Advanced Distributed...
Network virtualization is a promising concept to diversify the Future Internet architecture into separate Virtual Networks (VN) that can co-exist over a shared substrate network. To take full advantage of this paradigm this paper proposed a distributed trust model of VNs or services provided by VNs based on the Bayesian Network. The trust model is carried out by the trust model engine (TME) which...
Today, Massive Multi-player Online Game (MMOG) has taken an important part in the field of entertainment. But its increasing requirement of resources has brought a heavy burden to the game server. To address this problem, we propose a Structured Multi-Agent (SMA) model which divides the resources into groups by the Area of Interest (AOI) and builds itself on the pastry protocol. Then, every other...
This paper provides an introduction to simulation fundamentals via the Monte Carlo and next-event approaches to simulation, supported by two representative programs from the software suite written specifically for the Winter Simulation Conference's Simulation 101 workshop. The simulation libraries and functions associated with workshop are written using the R statistical language. R is suitable for...
A conventional Internal Model Control (IMC) method cannot be applied to solve the contradiction of the output tracking and the load disturbance rejection performance. In order to overcome the shortcomings of it, two-degree-freedom (2DOF) IMC is applied to solve the problem, but the conventional 2DOF-IMC has a complex control structure and method. This paper presents the modified 2DOF-IMC method that...
