A hierarchical model for object-oriented design quality assessment
No full textThe main reason behind failure of lots of software is poor quality thus estimation software quality become an important task in software industry. An early estimation towards pre-released software quality plays an important role in increasing probability of project success. By analyzing the metric data we can forecast the quality of the object oriented system. Software metrics are necessary to identify where the resources are needed; they are a crucial source of information for decision making. This paper represents proposed model for estimation quality of software product
Analytical Study of Common Rigid Bolt and Weld Steel Connections under the Effect of Heat
No full textOne of the most important members of steel structure’s connection region is beam-to-column connection. Rigid connection in steel moment frame has special role in the behavior of these structures and the fire resistance of these connections can be important. In this article the behavior of three common types of rigid bolt and weld connections under the effect of heat were studied by the use of numerical finite element methods through ABAQUS software. The models verified by the use of an experimental model through elastic and plastic amplitudes up to collapse and during numerical results, the effect of large deformation in the nonlinear region has also been considered. The results show that the connection with the end plate had a better performance against heat than other connections. Also reduced stiffness and lateral buckling in this connection was less than other connections
Resource Management Architecture in Dependable Real-Time Systems
No full textIn this paper we present adaptive resource management middleware techniques that achieve the QoS requirements of the dynamic real time system. The middleware performs QoS monitoring and failure detection, QoS diagnosis, and reallocation of resources to adapt the system to achieve acceptable levels of QoS. Experimental characterizations of the middleware illustrate its effectiveness for adapting the system for achieving the desired real-time and survivability QoS during overload situations. This paper presents resource management techniques that achieve the quality of service (QoS) requirements of dynamic real-time systems using open architectures and commercial off-the-shelf technologies (COTS).Dynamic real-time systems are subject to constant changes such as a varying external environment, overload of internal systems, component failure, and evolving operational requirements. The emerging generations of computer-based, command and control systems are the examples of such system
Web Interface for MATLAB
No full textCloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and unconfined with minimal management effort. Software is rapidly moving from the desktop to the Web and smart phones. Â Our work mainly targets the learning community by providing an efficient web interface for MATLAB by coalescing the two major concepts called cloud computing and open source which helps to diminish the troubles of portability, compatibility, power and storage space by making use of the concept of cloud compiler. And our MATLAB compiler allows a user to pick up the fastest or the most convenient tool to compile the code and remove the errors. The validity of our approach is then verified with the experimental results. This paper discusses implementation of Web based interface for compilation and execution of MATLAB language codes. Users can edit, write, compile, debug and store their code on server. Users need not to spend their time for finding and installing an IDE for different languages. User can use IDE in any device like PC, tablet and mobile devices which has browser with internet connection. Web Based IDE can be used in low configuration systems also.Â
Modeling of Natural Gas Dehydration Process to Prevent the Ice - Gas Phenomenon Using Artificial Neural Network
No full textDehydration has been done in several methods during past years, but due to multiplicity and complexity of effective variables of dehydration process, Modeling has been difficult. So, dehydration process has been done further by graphic methods and various relations so far. Hence prediction and modeling of dehydration process accompanied with approximately many errors; therefore in this study, artificial neural network was used to examine and identify effective input and output variables on dehydration process for designing and modeling. In order to train artificial neural network by experimental information that includes 7 input variables and one output variable (rotation rate), linkage established among input and output variables by MLP neural network with 7-6-1 pattern. Consequent results show that network error rate for predicting dehydration process is about 0.041% and correlation coefficient (r²) between network output and real output is 0.999

Automated Fault Tolerant Framework for Alchemi Desktop Grid Middleware
No full textA Fault Specific Automated Fault tolerant software system represent an Effective, Generalized solution in Resource Availability in the computational grid. In this Paper, We Revisit widely cited Fault Tolerance in computational grid. We have studied fault tolerated systems in domain of computational Grid. During this time we observed that there is lack of automated fault tolerated software system in domain of computational Grid. Crash and fault are very harmful in running computational grid. Alchemi middle ware is an open source Software structure that allow for painlessly collection of computing power of networked machinery into a virtual supercomputer. We have studied automated system in this area over last ten years. We repeatedly observed that, while Termination and Errors create trouble for aggregation of computing power. This difficulty is not specified in Computational grid. Our Refinements permit us to construct Automated Control system in Alchemi computational grid. In response to this, This Research Paper work leads to Automated Framework requisite for track normal and defective Process in Alchemi Desktop grid middleware. Execution Faults are directly concerned with Available computing Power. Our refinements allow us to Design Develop Automatic Software System for Direct Control on the Execution Processes. Proposed Automated framework is encouraging for manage and correct executer faults in Alchemi desktop grid middleware. Framework has ability to test imperfect resource and proficient to take control on execution machine .Framework is supportive to preserve level of obtainable computational power in Alchemi Desktop Middleware
A Compact Spade-Shaped Ultra-Wideband Planar Monopole Patch Antenna for Wireless Communication Systems
No full textIn recent years many studies are concentrated on UWB microstrip antenna structures for important purposes in wireless communication systems, medical imaging, and radar sensor resolution. In this paper, we printed a spade-shaped radiator patch on nearly rectangular substrate of (34 x 30mm) made of ArlonCuClad 250GT material. The relative dielectric constant was 2.55, and the thickness of the material was 0.8 mm. The patch was fed by a transmission line feeder, and there was a gap between the patch and the ground plane. Antenna design is simulated on electromagnetic (EM) simulation software , and anechoic chamber with a network analyzer was used during the experimental tests. The simulated results demonstrated that the proposed antenna achieved a wide impedance bandwidth from 2 GHz to 12 GHz with a return loss of less than -10 dB. The proposed antenna is easy to integrate with microwave circuitry for low manufacturing cost. The antenna structure is flat, and its design is simple and straightforward.Â

Application (ENG) properties for antenna miniaturization in WLAN and FWA frequencies
No full textOur purpose is to miniaturize the antenna, while maintaining a proper pattern, VSWR and bandwidth.. In this paper, we have simulated a U-shape dipole antenna on a glass substrate with 500 µm thickness for transparency application with ENG property, for WLAN and FWA (Fast wireless access) applications. The general dimensions of the designed antenna in this structure is . It is shown that using PEC plane in two sidewalls causes ENG property in glass. This property can be used to miniaturize the printed circuit antenna.
