Voice over Internet Protocol is a technology that enables to transport voice over Internet Protocol. The growth of this technology is due to the integration of voice and data traffic over wireless infrastructure. The low cost of voice usage on internet and wide spread of wireless technology has an advantage to implement VoIP system in today IP network. This study investigates the performance of VoIP...
In many fields of technology more mobile transmission paths will be used in the future. In order to ensure a secure transmission of data, studies for coexistence of the used radio technologies with other currently wide used radio systems (WLAN, Blue tooth, ZigBee, etc.), are needed. Since an analytical treatment is too complex and a real test set is usually too expensive, the objective is the construction...
A new statistical model for describing indoor wideband MIMO channels in train carriages is presented in this paper. Starting from a 3D ray tracing model, the most important parameters to obtain the wideband MIMO channel are investigated. The results are then used following WINNER methodology to create the channel model. To justify and validate this new model, the authors compare the model with the...
The dynamics of pedestrians have received less attention in transportation systems when compared to cars and other transportation means. However, its importance is inarguable and, recently, a lot of effort on research was put into this field. The use of Agent-Based Models (ABM) and known techniques such as the Social Forces Model (SFM) has fostered this most recent application field. Several models...
The paper describes several model, where the computer-aided software design system BPsim. SD was used. Some of them were existing projects with available output data, and were used for system verification as the baseline deployments. Namely, the University Information System is the project of such kind, and has been developed earlier, partially by authors, who had all the initial data to be able to...
Humanoids playing soccer are required to solve a great variety of tasks: from perception to body motion, from decision making to team coordination. On the other hand, results from this community are sometimes underestimated or unexploited because of the dedicated software developed. In particular simulators are often designed for a specific robotics platform or in some other cases the integration...
Due to the ever-increasing size of sequence databases, it has become clear that faster techniques must be employed to effectively perform biological sequence analysis in a reasonable amount of time. In bioinformatics, protein sequence alignment is one of the fundamental tasks. MPI-HMMER is one of the applications that perform this kind of bio-sequence analysis. Since the growth of biological data...
With our interest to reduce traffic congestion, simulations are necessary to investigate how to achieve this goal. Because of the difficulty of real-time experiments, traffic simulators are a good and widely used tool for analyzing specific situations of the traffic flow virtually. This paper introduces TraffSim, a new platform-independent framework, which is capable of simulating microscopic vehicular...
This article presents a dynamic simulation of an exothermic batch process using SIMULINK and Mat lab. The work considers design of a standard PID (Proportional- Integral-Derivative) controller with two scenarios of tuning setting. The designed control law is incorporated as a reactor temperature control loop, which usually represents a prime task in the batch process design. The paper shows that in...
In this paper, we present a study on dynamic simulation to assist designing a high performance compliant humanoid robot. An open source dynamic simulator is introduced which includes the rigid body and actuator dynamics of the full humanoid robot. A set of representative tasks for humanoid robot in rescue operations are chosen and simulated. The data from these tasks are used in sizing the motor and...
In order to access a high level processing, scalability and reliability, one needs to process machine level data in high level data processing and makes a connection between them (make them coherent). This paper is intended to monitor Delta PLC 14SS in .NET frame work, c#, by monitoring a glazier machine, it is aimed to describe how to address and to access inputs, outputs and memories of PLC which...
The exponential increase of urban areas in Africa during the last decade has become a major concern in the context of global climatic change and the increasing amount of impervious surface. Land-use models can assist decision makers in analyzing the underlying processes and estimate the impact of remedy actions. We used multi-temporal Land sat imageries for 1986, 2000 and 2010 to map urban land-use...
An approach to measure the relationship between sensor configuration and terrain backscatter using microwave modeling and measurement techniques is presented. Based on apriori synthetic aperture radar scattering models the investigation measured the far field electromagnetic wave reflectivity of four different barefaced terrains at microwave frequencies in an anechoic chamber. A system which includes...
This paper introduces a copy-move image forgery detection method based on local binary patterns (LBP) and neighborhood clustering. In the proposed method, an image is first decomposed into three color components. LBP histograms are then calculated from overlapping blocks from each component. The histogram distance between the blocks is calculated and the block-pairs having the minimal distance are...
In this paper, secure transmission is considered in a wireless relay network in the presence of an eavesdropper. A novel hybrid relay scheme, named as relaying-and-jamming (RJ), is advocated to achieve information theoretical security. In the RJ scheme, the relay node is equipped with multiple antennas. It responses for two missions: re-transmitting the information signal from source code and broadcasting...
This paper concerns the trade-off that may be madebetween the cost of storing intermediate data and thecomputing costs incurred in regenerating this data when large bioinformatics or other workflows are implemented using cloud resources. The implementation may be required todelete some data to keep storage costs within a budget, anddeciding how best to do this with minimal increase incomputing costs...

This paper presents the designed concept to improve the public key infrastructure deploy ability in the mobile ad-hoc networks routed by B.A.T.M.A.N. Advanced. We have extended the B.A.T.M.A.N. Advanced routing protocol with authentication and authorization of routing updates based on X.509 certificates. Furthermore we have determined several levels of node's trustworthiness and two levels of interoperability...
This paper describes the impact of connecting a new distributed generation to demand-dominated areas in electricity distribution network. The investigation is carried out by assessing three parameters of the network performance, i.e. voltage level, power losses and network utilization. The initial assessment is conducted on a reference network, which has several demand-dominated bus bars. Then, a...
Microgrid is a part of the power distribution system which uses renewable energy based of power generation connected to the grid system. Multi energy power generation is composed of renewable energy systems including photovoltaic, wind turbine, energy storage and local loads. Testbed of a microgrid system is the technique to ensure stable operation during faults and various network disturbances in...
