Linux network application framework can help programmers developing network service applications on Linux. Programmers can concentrate on the business logic of applications, and do not have to care about network transmission and serialization between client and server. In addition, application¡¦s client and server can be implemented by different programming languages and communicate with each other according to the programming languages supported by framework. This paper chooses Thrift and Etch to be the topic of Linux network application framework, and introduces their interface definition language, serialization and network architecture. This paper also makes experiments on the implementation of MongoDB, choosing of serialization and situation of multiple clients to a single server to get the performances of two frameworks. In general, Thrift has richer features and slightly better performance than Etch.

A thermodynamic framework was presented for the development of powderconstitutive models. The process of powder compaction through Equal ChannelAngular Extrusion (ECAE) at room temperature was modeled using the finiteelement analysis package ABAQUS. The simulation setup was used to conduct aparametric study involving varying the process parameters of ECAE, aimed ataiding the process design.Two powder compaction models, the Gurson model and the Duva and Crowmodel, were used to test their efficacy in modeling this process. Thethermodynamic framework was applied to derive the constitutive equations of theDuva and Crow model. Modeling parameters like friction coefficients, interactionconditions were determined by comparing the simulations for solid billet and anempty can with actual experimental runs for loads, shear angle and workpiece geometry. The simulations using the two powder constitutive models showed nosignificant difference in the stress in the powder during the extrusion.The results obtained from the 3-D simulations were also compared toexperiments conducted to compact copper powder with a size distribution of 10mto 45m. It was found through experiments that the powder does not fullyconsolidate near the outer corner of the workpiece after the first ECAE pass and theresults from the simulations were used to rationalize this phenomenon.Modifications made to the process by applying a back pressure during thesimulations resulted in a uniformly compacted powder region.Further, simulations were carried out by varying the process parameters likethe crosshead velocity, the friction coefficient between the walls of the die and thecan, can dimensions and material, shape of the can cross section etc and the effectof each of these parameters was quantified by doing a sensitivity analysis.

Views of strategy formulation can be mainly divided into two categories. One is I-O(Industrial Organization), the other one is RBV(Resource Based View)(Hitt, Ireland and Hoskisson, 1999¡G2003¡FSe-Hwa Wu, 2000¡FJoseph Shyu, 2000¡FCher-Min Fong, 2001¡FMing-Jer Tang, 2003).Both of vews have each suitable situation. If strategy is formulated from single view, it will cause defects (Robbins, 2003). Recent years, scholars provide solutions from integration¡Bcontingency and dynamic. However, thesis combines 3 features is still few. This paper attempts to find combined views to suit different situation in a dynamic framework. The research provides a static framework included¡G(1) If the contingency of inside and outside company are stable, companies ought to choose ¡uposition-based view¡v; (2)If the contingency of outside company are not stable but stable contingency of inside company, companies ought to choose ¡uvision-based view¡v; (3)If the contingency of outside company are not stable but stable contingency of inside company, companies ought to choose ¡uenvironment-based view¡v; (4)If the contingency of inside and outside company are both not stable, companies ought to choose ¡uresource-based view¡v; (5)If the contingency of inside and outside company are changing smoothly with controllable situation, companies ought to choose ¡uconstruction-based view¡v. The research provides a dynamic framework. From the long term view, a company needs to adjust itself to match the changing of situation in order to have sustainable competitive advantage.

Electronic customer relationship management (e-CRM) emerges from the Internet and web technology to facilitate the CRM implementation. It focuses on internet- or web-based interaction between companies and their customers. Especially, e-CRM enables service sectors to provide appropriate services and products to satisfy the customers so as to retain customer royalty and enhance customer profitability. This research is to explore the key research issues of e-CRM performance influence. A research model is proposed based on the widely applied technology- organization-environment (TOE) framework. Survey data from the questionnaire are collected to empirically assess our research model. With the structural equation modeling (SEM) analysis, the results show that e-CRM technology and organizational support are positively related to the e-CRM performance, while environmental pressure, though a drive to e-CRM adoption, does not impact the performance. More interestingly, it is observed that organizational support has a greater impact than e-CRM technology adoption. It is always a good principle to care customers¡¦ relationship more from human nature perspectives than from technology-oriented considerations. Also, in the aspect of organizational support, skilled and knowledgeable e-CRM personnel are the most important impacting factor among others. Finally, the contributions of our research lie in that not only the results can provide researchers a good starting point for e-CRM studies, but also can they provide practitioners of service sectors in Taiwan a good reference.

Video on demand (VoD) services are becoming more and more popular today. As high bandwidth communication infrastructure is being established in many countries around the world, high bandwidth communication lines will reach millions of family in the near future. Due to the increasing improvement of communication technology, more and more families enjoy the VoD services which are provided by telecommunication companies and cable TV provider via the Internet. In such a case, scalability and fault tolerance will be the key issues. We propose an architecture for VoD services which is based on multi-server circumstance. In our proposed architecture, each movie is replicated on a subset of the servers. When a server crashes or disconnects from its clients, it is replaced by another server in a transparent way. Regarding of load balancing problem, clients are also migrated from one server to another when a new server is brought up. The benefit of our service is to use common hardware and general network technologies (e.g. TCP/IP). In addition, we provide a machine-independent environment to let the servers and clients execute on any machine through the network. Furthermore, we can get the media players from a web browser by utilizing the cross-platform characteristics of Java. The client host does not need to install any relevant applications. Since Java Media Framework (JMF) provides a unified architecture and messaging protocol for managing the acquisition, processing, and delivery of time-based media data. It can support many standard media content types, such as AIFF, AVI, MIDI, MPEG, QuickTime, and WAV. Using JMF, we can create applets and applications to present, manipulate, and store time-based media.

<p>Component-based Software development is a promising way to improve quality, time to market and handle the increasing complexity of software management. However, The component-based development is still a process with many problems, it is not well de_ned either from theoretical or practical point of view. This thesis gives a brief overview of Component-Based Software development and starts with brief historical evolution followed by a general explanation of the method.

The central contention of this dissertation is that political scientists have largely ignored the importance of ideational frameworks for resolving problems of policy-making in times of significant upheaval. In order to illustrate the genesis and contribution of these frameworks, the three papers in my dissertation focus on a diachronic comparison of two moments in Russian history that encapsulate maximal uncertainty, covering the aftermath of the imperial collapses in 1917 and 1991. The first paper focuses on state- and nation-building in the North Caucasus, arguing that the debates between the Bolsheviks and other members of the Second International, particularly Otto Bauer, provided the Bolsheviks with a coherent platform that could largely stem the fissiparous tendencies of the region in a way that Boris Yeltsin and his teams were unable to do in the early 1990s. The second paper examines economic policy and finds the reverse to be true: the economic debates of the Second International largely ignored the problem of the peasantry and the exiled status of many of the leading Bolsheviks meant they were unable to articulate a sufficiently detailed policy to apply to the Russian case. The post-communists under the leadership of Yegor Gaidar, were able to draw on decades of economic research, particularly the Chicago and Virginia Schools, that provided the intellectual rationale for dismembering the Communist command-system, but equally important was the years that Gaidar and his team spent developing an alternative in the twilight years of communism. The final paper considers the legacy of ideational frameworks by considering the rule of Stalin and Putin, arguing that the tasks left unfulfilled provide a basis for regime consolidation by subsequent rulers. / Government

Handwriting is a complex occupation; it is an intricately coordinated symphony of skills and interactions. The success of a child’s handwriting is dependent on many factors and conditions. The concept of occupational justice implies, as a determinant of health and well-being, all children have the right to access sound handwriting instruction and if required, supportive services for therapeutic intervention. However, a number of school-aged children do not have access to sound handwriting instruction or therapeutic intervention. This is an occupational injustice. An integrative review of the occupational therapy literature was completed for the purposes of enhancing the understanding of handwriting in the school system. The Revised Framework of Occupational Justice was used to guide the analysis of the literature sources and identify the conditions contributing to an occupational injustice. The results of this review provided a comprehensive overview of handwriting and identified conditions leading to an occupational injustice in handwriting.

Pelagic ecosystems are inherently complex in coastal inlets where they are controlled by physical processes and influenced by biogeochemical and foodweb interactions. Meteorological events are important drivers of this ecological variability. This thesis investigates their effect on the plankton dynamics of Lunenburg Bay, an inlet on the Atlantic coast of Nova Scotia (Canada). In this region, meteorological events are dominated by upwelling in summer, which are a dominant source of flushing and nutrient variability for the inlets. Despite these events, which induce phytoplankton blooms in other regions, the concentration of phytoplankton as chlorophyll remains relatively low throughout the summer in Lunenburg Bay. To reveal the underlying processes limiting the development of phytoplankton biomass, and therefore to improve our understanding of the factors regulating plankton dynamics in this inlet, the objectives of this thesis are to determine the main drivers of variability in phytoplankton biomass and plankton community structure, and to identify the factors limiting the development of phytoplankton biomass in Lunenburg Bay. For that, I use a dataset collected at a coastal observatory located in Lunenburg Bay that covers the years 2003–2006, complemented by a series of transects carried out in summer 2006. The dataset covers physical, chemical and biological properties of the bay, including plankton taxonomy. Two types of physical-biological coupled models are developed: a low-resolution box model of Lunenburg Bay with steady-state wind forcing, and a high-resolution nested model of Lunenburg Bay using the Regional Ocean Modelling System (ROMS) to hindcast a series of upwelling events in 2006. The results reveal that four factors regulate the phytoplankton response to upwelling events in Lunenburg Bay, namely (1) the duration of an upwelling event, (2) the low nitrate concentration in source waters, (3) the flushing rate of the inlet (hence transport), and (4) the bathymetry along the inshore-offshore axis of the bay. In addition, (5) the occurrence of upwelling and (6) the inshore-offshore gradient of increasing depth influence the structure of respectively phytoplankton and zooplankton communities, indicating a dissimilarity in the processes structuring plankton communities in the lower food web. A conceptual model is then developed to describe the role of transport and nitrate concentration in source waters in controlling plankton dynamics in an inlet.

The use of multimedia content on the web has grown significantly in recent years. Websites such as Facebook, YouTube and Flickr cater for enormous amounts of multimedia content uploaded by users. This vast amount of multimedia content requires comprehensive content modelling otherwise retrieving relevant content will be challenging. Modelling multimedia content can be an extremely time consuming task that may seem impossible particularly when undertaken by individual users. However, the advent of Web 2.0 and associated communities, such as YouTube and Flickr, has shown that users appear to be more willing to collaborate in order to take on enormous tasks such as multimedia content modelling. Harnessing the power of communities to achieve comprehensive content modelling is the primary focus of this research. The aim of this thesis is to explore collaborative multimedia content modelling and in particular the effectiveness of existing multimedia content modelling tools, taking into account the key development challenges of existing collaborative content modelling research and the associated modelling tools. Four research objectives are pursued in order to achieve this; first, design a user experiment to study users’ tagging behaviour with existing multimedia tagging tools and identify any relationships between such user behaviour; second, design and develop a framework for MPEG-7 content modelling communities based on the results of the experiment; third, implement an online service as a proof of concept of the framework; fourth, validate the framework through the online service during a repeat of the initial user experiment. This research contributes first, a conceptual model of user behaviour visualised as a fuzzy cognitive map and, second, an MPEG-7 framework for multimedia content modelling communities (MC2) and its proof of concept as an online service. The fuzzy cognitive model embodies relationships between user tagging behaviour and context and provides an understanding of user priorities in the description of content features and the relationships that exist between them. The MC2 framework, developed based on the fuzzy cognitive model, is deep-rooted in user content modelling behaviour and content preferences. A proof of concept of the MC2 framework is implemented as an online service in which all metadata is modelled using MPEG-7. The online service is validated, first, empirically with the same group of users and through the same experiment that led to the development of the fuzzy cognitive model and, second, functionally against the folksonomy and MPEG-7 content modelling tools used in the initial experiment. The validation demonstrates that MC2 has the advantages without the shortcomings of existing multimedia tagging tools by harnessing the ease of use of folksonomy tools while producing comprehensive structured metadata.
