Designing business process is very complex as it involves activities, resources, products and tools. Adopting the concept of domain specific modeling helps creating and using business processes, packaged as services and enable reusability, loose coupling, higher abstraction, agility, and interoperability. Domain specific modeling can be used to design the business processes as it increases the business...
The distributed file system (DFS) provides a mechanism where a file can be stored across several physical computer nodes ensuring replication transparency and failure transparency. In order to achieve this, one important feature of DFS's data structure is to employ a proper way to organize the large scale data and file namespaces to provide a fast access speed. In order to analyze file namespace issue,...
In a distributed file system, operations such as read, write, send and receive should be efficient and must increase the overall performance of the system. Especially every remote read and write operation we encounter network and secondary storage latencies. In order to reduce this latency time and improve the performance of distributed file system, we analyze the problem of selecting application-level...
Key management is a decisive part for security in wireless sensor networks. Pre-distribution of secret keys for all pairs of nodes is not viable due to the large amount of memory used when the number of sensor node is huge. Recently, a random key pre-distribution scheme is proposed as an efficient solution for sharing keys among sensor nodes to reduce the length of shared key and avoid unnecessary...
Character animation toolkits are very essential tools for animators in computer graphics world. These tools can make the work of animators extremely easy. Each tool can be applied to different body parts of character or the whole character. The tool that is described in this paper helps animators for creating character hand's animation. Hands of character in animation play one of essential roles for...
Information technology is moving towards the next generation and is attaining a new paradigm shift with the development of new technologies and its impact towards application development are inevitable. In particular, the focus on Web services (Web 2.0) are increasing and currently it is been considered as a platform rather than service, due to its capability of data integration and working jointly...
Enterprise service bus (ESB) provides a layer on top of an implementation of an enterprise messaging system. The ESB provides a highly distributed, event-driven service oriented architecture (SOA) that combines message oriented middleware (MOM), Web services, intelligent routing based on content, and XML data transformation. ESB transmits and receives standard set of messages. When it receives a message,...
The environment-aware communication model with respect to ultra-large-scale system senables self-growing system and its users to form a Web Ecosystem. In such an environment, the Web systems and users are habitants of same place and are aware of each other. The Web Ecosystems semantically solve the problems of users and improve their knowledge using metadata interchange among systems. In line with...
Recently, due to the rapid development of IT technology and the penetration of internet through super high-speed internet network, lots of network-enabled multimedia devices are spread in the home network. However, there are integration and management problems because of their incompatibility. In this paper, we propose home multimedia integration system that integrates multimedia devices and services...
In this paper, we present an energy-efficient data dissemination protocol (EEDD) for wireless sensor networks with mobile sinks. This protocol considers energy-efficient consumption and network lifetime especially to sensor networks with high node density. The protocol is based on grid structure and location aware flooding of sensor networks to gain effective data dissemination between sources and...
Web service orchestration studies composition of already-existing Web services to create new value-added services. The composite Web services could be executed in a centralized or peer-to-peer (P2P) orchestration model. Compared with centralized-orchestration model, the P2P-based orchestration model provides better scalability, reliability, and performance for the overall services. Unfortunately,...
CRM focus on managing the relationship between a company and its current and prospective customer base as a key to success. A good relationship with the customer leads to higher customer satisfaction. Despite its importance the failure rate is higher because of the implementation and integration problems. We are trying to address this issue by developing the CRM system using GME through meta-model...
Summary form only given. We present detailed experimental results of surface flashover (or breakdown) at a dielectric window transmitting a focused Gaussian beam of high-power millimeter waves. The experiments have been conducted using a 110 GHz gyrotron with maximum output power of 1.5 MW and pulse length of 3 microseconds. Results so far have been at atmospheric pressure. Diagnostics include optical...
A single-stage depressed collector has been installed on a 1.5 MW, 110 GHz gyrotron and tested in 3 microsecond pulse operation at 96 kV and 40 A. The overall efficiency with the depressed collector was 50 % at 1.5 MW of output power with a voltage depression of 25 kV. Theory predicts up to 35 kV of depressed voltage for these operating conditions. The discrepancy between the experiment and the theory...
As the next generation of Internet services requires more highly scalable and available server systems, the cost-effective cluster of a large number of distributed computers becomes a popular solution. In this paper, we investigate to design and develop a server load balancing mechanism on cluster architecture, called the ALBM cluster. In order to construct the more scalable and reliable Internet...
