there is a more challenging demand nowadays for software organizations to deliver high quality product on time with low budget. Software processes help them achieve this goal, gain their customer satisfaction, accomplish competitive advantage and satisfy their shareholders financial demands. Agile and traditional development approaches divided the software market into two competing parties, each legitimately defending its party knowing it strengths and weaknesses. this paper proposes a new Hybrid model that combines both methodologies to overcome their weaknesses and make use of their strengths; resulting in a mature, and a professional software model. A software tool is also being developed to automate this model's practices.

A perennial problem with running modern e-business systems is to manage supply chains cost-effectively. To get the maximum efficiency a higher degree of automation is required. this research intends a preliminary step towards automated supply chain integration and optimization through a research prototype that models supply chain management scenarios. It will show under such an approach potential cost and timesavings, as well as an optimization strategy that could be delivered in a real-time fashion. Additionally an empirical study using the prototype will be undertaken to show the difference between combinatorial and heuristically guided optimization rules in optimization of supply chains. the prototype will use Service Oriented Architecture (SOA) techniques to initialize, coordinate and monitor the supply chains.

Recently, the use of digital watermarking has increased, primarily for copyright protection of E-commerce sites and mobile applications. Digital watermarks are highly dependent on the installation platform and OS, and cannot be applied universally, although their components are often used by various developers. In addition, withthe recent diversification in the functions available via Web applications and mobile applications, the scope of development has increased considerably, becoming a real and substantive problem. In particular, cryptographic technology and DRM technology including digital watermarking, which require high performance and place a high load on systems due to their complex operation processing, are considered to be relatively difficult to implement. In this study, we aim to develop object-oriented solutions for these uncertain problems, focusing in particular on architecture and implementation.

An auction model is used to increase the individual profits for market players with products they do not use. A Financial Transmission Rights Auction has the goal of trade transmission rights between Bidders and helps them raise their own profits. the ISO plays a major rule on keep the system in technical limits without interfere on the auctions offers. In some auction models the ISO decide want bids are implemented on the network, always withthe objective maximize the individual profits for all bidders in the auction. this paper proposes a methodology for a Financial Transmission Rights Auction and an informatics application. the application receives offers from the purchase and sale side and considers bilateral contracts as Base Case. this goal is maximize the individual profits within the system in their technical limits. the paper includes a case study for the 30 bus IEEE test case.

Various forms of pervasive computing environments are being deployed in an increasing number of areas including hospitals, homes and military settings. Entities in this environment provide rich functionalities (i.e. services). How to organize these heterogeneous and distributed entities to deliver user-defined services is challenging. Pantagruel is an approach to integrate a taxonomical description of a pervasive computing environment into a visual programming language. A taxonomy describes the relevant entities of a given pervasive computing area and serves as a parameter to a sensor-controller-actuator development paradigm. the orchestration of area-specific entities is supported by high-level constructs, customized with respect to taxonomical information. Pantagruel is also a language that describes and manages services. Further more, Pantagruel can be viewed as a high level service contract between the service designer and the program implementer. this paper presents a formalization of Pantagruel, both its syntax and semantics. Four kinds of static properties are stated based on the formalization. Predicate abstraction based algorithms are designed to verify the properties.

Mobile agents' paradigm and technology is emerging as a powerful tool for engineering highly dynamic, reconfigurable distributed systems and applications in heterogeneous environments. this paper proposes a statecharts-based development process for implementing atomic read/write shared memory in mobile ad hoc networks(geoqurums approach), which allows for a seamless transition from the specification of mobile agent behavior to its implementation and adaptation to target mobile agent systems. In particular. modeling of the mobile agent behavior is visual and its coding is seamlessly supported by the Mobile Active Object Framework(MAOF). the coded agent behavior can be adapted to platform-specific mobile agents by means of the Mobile Agent Adaptation Framework(MAAF). thus, enabling re-use of existing mobile agent systems.

Open source software (OSS) has been widely accepted as one of reuse methods to develop software applications in industry. OSS is well known for free software which can be used with freedoms on costs and copyrights. Nonetheless, when it comes to compliances of OSS licenses, different licenses have different duties to which users should conform. Furthermore, if the software using OSS is commercial, the conformance of OSS license compliances gets more critical. However, it is not easy for the commercial software developers to fully comply with compliances of OSSs due to the absence of a support system a management system allowing the developers to satisfy the compliances. In this paper, we present a practical management framework for commercial software development with OSS. In the framework, we define a development process including activities, instructions, and artifacts to use OSS. We also present practices on providing infrastructure and organizational support as well as defining education curriculum. And finally we discuss lessons, issues, and further directions.

this paper presents an approach to automatically distinguish the copied clone from the original in a pair of clones. It matches the line-by-line version information of a clone to the pair's other clone. A case study on the GNOME Desktop Suite revealed a complex flow of reused code between the different subprojects. In particular, it showed that the majority of larger clones (with a minimal size of 28 lines or higher) exist between the subprojects and more than 60% of the clone pairs can be automatically separated into original and copy.

Deformation mechanisms of Mg89Zn4Y7 (at.%) extruded alloy, which is mostly composed of LPSO-phase, was investigated focusing on their temperature dependence. the yield stress of as-extruded alloy showed extremely high value of similar to 480 MPa at RT, but it largely decreased to similar to 130 MPa at 300 degrees C. the decreasing rate of the yield stress could be significantly reduced, however, by the annealing of specimen at 400 degrees C, by suppressing the microyielding which is considered to occur related by the grain boundary sliding in restricted regions. the yield stress of the annealed specimens with random textures could be estimated by the liall-Petch relationship by regarding the length of long-axis of plate-like grains as a grain size between RT and 300 degrees C. the yield stress of the annealed specimens maintained high values even at 200 degrees C, but it also showed large decreases at 300 degrees C.
