Web-Services can be referred as a family of technologies that standardized the communication of applications through world wide web in a cost-effective manner. Few of the major software vendors like IBM, Microsoft, Oracle, SAP are all embracing the web service standards into the newer versions of their applications which are web services enabled. All the constrains like cost, time, space for discovering, and e-business transactions can be solved easily by using web-services. With the introduction of these Web services design of the business application to provide service, integrating with other business entities, and conducting business transactions completely changed the working of a business organization. These web-services became a viable component in distributed E-Commerce platforms. In determining server response time, high speed communication systems along with computing capacity and network latency have become important. In web technologies a new model of architecture for distributed E-Commerce applications has been proposed which aims at integration and inter-operation between different platforms. In this paper we have proposed a model for developing an E-Commerce application using the Spring framework which helps in easy integration with other frameworks and solves most difficulties in an enterprise application development.<br>

The power of Web services to address the incompatibility issue of standalone systems, has led them to play a major role in business application development. Adopting an efficient and effective method to locate and select desired services among thousands of available candidates is an important task in the service-oriented computing. As part of a Web service discovery system, the ranking process enables users to locate their desired services more effectively. Many of the existing approaches ignore the role of user's requirements which is an important factor in the ranking process. In this thesis we enhance a vector-based ranking method by considering user's requirements. The vector-based model is chosen because of its simplicity and high efficiency. We evaluate all Web services in terms of their similarity degrees to the optimal or the best available values of each quality attribute, and penalize the services that fail to meet the user's requirements. Through our extensive experiments using real datasets, we compare the improved algorithm with other approaches to evaluate it in terms of efficiency (the execution time to return the result) and quality of the results (accuracy).

Basic Features

In the past decade, a computer aided method for design evaluation of high-speed tracked vehicles with flexible tracks (or tracks with relatively short track pitch commonly in use in tracked transport vehicles and military vehicles) has been developed. It has been successfully used in assisting vehicle manufacturers in the development of new products and governmental agencies in the selection of vehicle candidates. For low-speed tracked vehicles commonly in use in agriculture, construction and logging, rigid tracks with relatively long track pitch are employed to achieve a more uniform ground pressure distribution. To assist manufacturers of this type of vehicle to expedite the development of new products in a cost effective manner, a computer aided method for design evaluation of tracked vehicles with rigid links has recently been developed. It treats the track as a system of interconnected rigid links and takes into account the characteristics of the interaction between track links and deformable terrain. The basic features of the method have been verified by field test data. The method can be an extremely useful tool for the engineer to optimize vehicle design and for the procurement manager to select appropriate vehicle candidates to meet specific operating requirements.

Free-space optical (FSO) communication systems are being anticipated to offer promising alternatives to existing radio networks in delivering high-speed data access to end-users. Ease of installation, robust features, and cost-effective operation have been the hallmark of FSO systems, and these features will play an obvious role in deciding the ways in which futuristic smart communication models will operate. Despite these arrays of features, FSO links suffer severe performance degradation due to channel-induced impairments caused by atmospheric effects such as rain, haze, and fog. In this work, we have investigated and compared the performance of 40 Gbps FSO links for different channel conditions ranging from clear weather to severe attenuation by incorporating spatial and wavelength diversity as performance booster techniques. The use of an erbium-doped fiber amplifier (EDFA) with FSO links has also been proposed here. Using performance metrics like bit error rate (BER) and eye patterns, it has been found that the use of EDFA not only helps in compensating for the link losses but also aids in realizing an all-optical processing based last-mile access system. The proposed FSO system will be capable of bridging the existing backbone fiber networks with end-users with minimal changes to the existing hardware regime, thereby proving to be extremely cost-effective in sharp contrast to radio-frequency generations which require major infrastructure overhaul.

Oceanic Environments

Ever-increasing human activities in oceans require handy, reliable and cost-effective high-speed network access similar to terrestrial Internet services to be available on and under water. However, terrestrial Internet cannot be extended to oceans seamlessly due to huge differences between terrestrial and oceanic environments, while satellite services are still very expensive especially for ordinary users with communication quality susceptible to weather conditions, and cannot cover underwater networks either. Therefore, marine Internet, proposed about six years ago, is the earliest scheme that tries to systematically address the internetworking issue in oceans and still in its infancy stage. This tutorial aims to introduce the principle, architecture and applications of marine Internet, along with discussion on oceanic environments for communication, currently available and under developing communication systems in oceans, as well as challenging issues necessary for further studies to foster the development of marine Internet.

Ultra-Wideband (UWB) systems are widely used in low-power, high-speed, high-security short-range wireless communication systems throughout digital homes and offices. In the RF front-end of a UWB system, bandpass filters (BPFs) are used to put through the passband signals and reject the stopband signals. Most UWB BPFs are designed with dielectric materials on circuit boards or LTCC technology. In this paper, a very compact fully integrated UWB chip filter is proposed and designed on a GaAs substrate with nitride as dielectric layers to meet the small size requirement of portable devices for next-generation UWB applications. The filter is constructed with a modified Chebyshev structure. The final filter circuit contains only four inductors instead of six for the conventional Chebyshev filter, which makes the chip more compact and cost effective. The filter is designed and fabricated on a 0.25 μm GaAs pHEMT technology with a chip size of only 0.73 mm × 0.51 mm including the chip edge and scribe line area, while the filter core area is only 0.61 mm × 0.39 mm, including bonding PADs. The measurement results illustrated that the proposed BPF shows a passband covering the frequency range of 3.1–9.0 GHz, the minimum passband insertion loss is only 1.5 dB, the stopband rejection is better than −30 dB throughout frequencies below 2 GHz and above 12 GHz, S11 is less than −16 dB, and S22 is better than −11 dB during the whole passband range. It demonstrated that the proposed filter can be considered as one of the most compact UWB filters.

Three levels of planning can be distinguished in grassland farming: strategic, tactical and operational. The purpose of strategic planning is to achieve a sustainable long-term fit of the farm business with its physical, social and financial environment. In pastoral farming, this essentially means developing plans that maximise and best match pasture growth with animal demand, while generating sufficient income to maintain or enhance farm resources and improvements, and attain personal and financial goals. Strategic plans relate to the whole farm business and are focused on the means to achieve future needs. They should be routinely (at least annually) reviewed and monitored for effectiveness through key performance indicators (e.g., Economic Farm Surplus) that enable progress toward goals to be measured in a timely and cost-effective manner. Failure to link strategy with control is likely to result in unfulfilled plans. Keywords: management, performance
