In tourism industry, a challenge is how to handle emergency situations during a journey. Although most of the tourism travel agencies focus on generating travel plans, an important part that has been ignored is to provide a creative emergency travel plan when a user meets an unforeseen situation during the journey. Thus, in order to address problems like this, the study to build a system that can...
This paper deals with the methodology of software to promote optimised operation of the transmission network. The methodology is based on the real data referring to operating temperatures and the power transmitted over 220 kV and 400 kV lines. This is an input database, formed by the values of power transmitted at a real time temperature. The software designed here offers a choice of the line to be...
Open source Development Model Algorithm (ODMA) is one of the recently proposed heuristic algorithms that is inspired by open source software development mechanism and community's behaviors. The superior performance of this algorithm has been proven among the other most well-known algorithms such as genetic algorithm (GA) and particle swarm optimization (PSO). However, the original version of this...
High efficiency video coding (HEVC) standard, introduced by joint collaborative team on video coding (JCT-VC) is the newest international standard of video compression. This standard provides more compression and better video quality, compared to the previous standards such as H.264. The higher compression efficiency is obtained at the cost of an increase in the computational load. One of the portions...
This paper describes a novel modular design of an autonomous management distributed system (AMDS) for cloud computing environments and it presents its implementation with the Scala programming language. The AMDS was designed from the ground up with distributed deployment, modularity and security in mind, using a full object oriented approach. A key feature of this system is the ability to gather and...
The European Electronic Toll Service (EETS) allows different possibilities for the overall system design of interoperable toll systems. We study the effect of the overall system design on the operational costs using a model based, holistic, executable specification. The model is set up to give an accurate description of the interdependences as seen in the German toll system. Two different scenarios...
In this paper, we use an FPGA platform and a high level synthesis tool, called Impulse C, to speedup a statistical Line Of Reaction (LOR) estimation for a high-resolution Positron Emission Tomography (PET) scanner. The estimation algorithm provides a significant improvement over conventional methods, but the execution time is too long to be practical for clinic applications. Impulse C allows us to...
To make the crank slider protective devices to meet the requirements of regulation, optimization was carried out to the absorbing thread of the crank-slider-CST protective device. Based on the finite element model in VPG and simulation in LS-DYNA, with the orthogonal optimization design, obtained the parameters of the absorbing thread. The crash speed in these simulations is 50km/h, which is higher...
Ant colony algorithm is a bionic optimization algorithm, it can solve combinatorial problems effectively. For the problem of the test suite reduction, this algorithm could find the balance point between the speed and the accuracy of solution. Unlike other existing algorithms, this algorithm used test cost criteria, as well as the test coverage criteria. Finally, the paper presented the results, the...
Mobile platforms have the resource-constrained characteristic, demanding to optimize the program to make up for the relative lack of resources. In this paper, using Symbian C++ as the development language, mainly optimize the code side and display side for the Symbian platform applications. Experimental results show that the technique improves efficiency and user experience degree.
In this paper, we present different modeling and execution frameworks that allow us to efficiently analyze, design and verify complex systems, mainly to cope with the specific concerns of the Real-time and embedded systems (RTE) domain. First we depict a UML /MARTE based methodology for executable RTE systems modeling with a framework and its underlying model transformations required to execute UML...

Programming with atomic sections is a promising alternative to locks since it raises the abstraction and removes deadlocks at the programmer level. However, implementations of atomic sections using software transactional memory (STM) support have significant bookkeeping overheads. Additionally, because of the speculative nature of transactions, aborts can be frequent greatly lowering application performance...
In this paper we will present a new framework for the work flows of distributed integrated systems by assessment of effective factors. This framework which has a higher efficiency compared with other frameworks has been assessed and will be presented within the ERPWKM framework using established phases. The proposed framework compares decision-making processes in various phases and reduces data processing...
According to the working features of the drawing press,the article discusses its optimization design, how to establish the model and analyse dynamics based on Virtual Prototyping (VP) technology which integrates CAD, CAE and visual technologies, etc., and compared the simulative results and theoretic results. The results show that the motion characteristics of optimization model can meet to the sheet...
In cyclic (or alternating) method, the full parameter vector is divided into two or more subvectors and the process proceeds by sequentially optimizing each of the subvectors while holding the remaining parameters at their most recent values. One example of the advantage of the scheme is the preservation of large investments in software while allowing for an extension of capability to include new...
Quantitative in silico modeling is a powerful means to enhance our understanding of complex biological systems. Accordingly, intuitive and flexible computational tools are needed to support the development of such models. We previously developed the platform EPISIM for graphical modeling and simulation of cellular behavior in epithelia. In this work we demonstrate how computationally efficient software...
Due to the severe competition and budget constraints in the telecoms market, many network operators are exploring different ways to reduce their operating cost while still providing excellent services to their customers. One of the possible savings that can be made is to apply software planning tools to automate and optimize network designs at the lowest possible cost. This paper describes how a novel...
