In this paper new segmentation techniques based on region growing algorithm are proposed and tested by using images from different sources. Seed regions are an important step in region growing algorithm, many of region growing algorithms are identified either manually or by automatically. The results showed the automatically identification of the seed regions is the best and give more accurate results than manually identification. The Canny edge detection is used to identify the edge regions, and Symlet wavelet family gave the suitable results to identify edges based on two-dimensional wavelet transform. The enhancement step is necessary to group the values of neighboring pixels together. The results have been shown that the enhancement step using Gaussian filter reduced each of the number of the seed regions and the number of the colored regions. The Gaussian filter based on the value of the standard deviation, the results showed the suitable value of the standard deviation was (1) and may be set between (1) and (3.5), more than this range the image will be degraded.

Under the considerations for the rapid development in leisure tourism and the demand increase for resort hotels, most enterprises will meet a pressure of drastic competition. Therefore, they will intend to build a unique brand in the mind of consumers and to enhance competitiveness and increase their profits. In this study, we will address the issue on the position of brand equity and key factors of competition for the resort hotels. The questionnaire method will be applied to collect the data and the resort hotels in Kenting area will be taken as an illustrative example in our study. The primary findings of this study can be summarized as follows: 1. Customers will have a higher degree of recognition for the environmental quality, local quality and uniqueness brand to the resort Hotels in Kernting area. 2. According to the brand equity diagram derived by using the multi-dimensional scaling (MDS) to those tourists at kernting area, we can find out that those resort hotels can be clustered into four clusters. 3. The brand equity model can be constructed well via using the conventional discriminant analysis and the backpropagation neural network technique. And, the full model and the reduced model can be also constructed after screening the important factors. From above findings, it can provide the useful reference about the marketing strategy and differentiation competition for the resort hotels in Kenting area. It will aid the competition analysis since the enterprise would like to realize their position on the competition environment via the brand equity cognitions.

Mobile Ad Hoc Networks are communication networks built up of a collection of mobile devices which can communicate through wireless connections. Mobile Ad Hoc Networks have many challenges such as routing, which is the task of directing data packets from a source node to a given destination. This task is particularly hard in Mobile Ad Hoc Networks: due to the mobility of the network elements and the lack of central control, robustness and adaptability in routing algorithms and work in a decentralized and self organizing way. Through the principles of systems architecting and engineering, the problem statement in Mobile Ad Hoc Networks could be defined more specifically and accurately. The uncertainties and techniques for mitigating and even taking positive advantages of them can be achieved through a framework of uncertainties as in [1]. The systems methodology framework called Total Systems Intervention (TSI) described by Flood and Jackson [2] select a systems methodology for Mobile Ad Hoc Networks. The purpose of this paper is to show how TSl when integrated with a framework created to understand the risks and opportunities can help develop strategies to minimize the risks and to take advantage of the opportunities for facing challenges in Mobile Ad Hoc Networks. ©2008 IEEE.

An assignment-based heuristic for vehicle routing with time windows

Operational Research 2008年第3期8卷 219-233页

作者： George Ioannou Manolis N. Kritikos Gregory P. Prastacos Management Sciences Laboratory Graduate Program in Decision Sciences Department of Management Science and Technology Athens University of Economics and Business Athens Greece

In this paper, we consider the typical vehicle routing problem with time window constraints (VRPTW). The problem is approached via mathematical decomposition and solved using a three-stage method. First, we formulate the generalized assignment problem, which provides an approximation to the sequencing of customers that partially respects the time windows and apply the Hungarian method to obtain optimal solutions. Subsequently, we address the split of infeasible routes resulting from the assignment solution using a simple, time window-based decomposition heuristic. The best of these routes, in terms of traveling and vehicle waiting times, form part of the final solution, which is completed by the routes provided by a look-ahead heuristic applied to the remainder of the customers. The proposed method is applied to a standard literature data set, and provides very good results with respect to both the number of vehicles and the total travel time. Furthermore, the approach offers useful insights on the effect of employing optimal travel time solutions resulting from the assignment relaxation to derive partial route sets of VRPTW.

Recommendation accuracy is especially important in mobile e-commerce environments due to the limited screen size of mobile devices and relatively expensive connection costs. Mobile content tends to be fashionable and are geared for young users. This paper presents a novel method of building a more accurate recommender system for mobile content in a mobile ecommerce environment. The method is based on collaborative filtering, and models content diffusion and user preference transition and incorporates them in constructing pseudo ratings from implicit feedback data. In a variety of experiments, recommender systems based on the method showed significantly better recommendation accuracy than a pure collaborative filtering-based recommender system.

Most industrialized countries have been able to insert innovation into their national agendas, leveraging competitiveness, economic growth and social development. Well structured national innovation systems run across all the innovation value chain: from the transfer of ideas or inventions, to their commercialization as high value and differentiated products or services, producing high economic and social impacts In developing countries, the circumstances are quite different. There are weak liaisons, low trust and poor association between economic generators (companies) and their supporting institutions (government, federations, banks and academies). Regions are not electronically prepared (e-readiness) to support the infrastructure required for the effective formation of clusters (e-readiness). Innovation is not perceived as an asset, and high value entrepreneurship is not a common finding in the entrepreneurial profiles of most professionals. There are no world class industrial enabling conditions, nor high value core capabilities, and the digital economies are creating large digital development divides instead of business opportunities. In general, the economic gap between rich countries and poor ones widens every day. To help alleviate this situation, we have developed the WIT Model (Wealth creation through Innovation and enabling Technologies). This model has been designed to create the necessary and sufficient enabling conditions and core capabilities to empower developing regions to transform their scarce resources and hostile conditions, into attractive regions with competitive industries and innovative companies, capable of producing great added and differential values, strongly interrelated with their regional social capital, so that they can compete globally as extended networks of value, and share their economic value among their local communities. Several cases of application of the model are shown, specially the current project of the Institute for Inn

Wang et al. [1] proposed a multiple-stream yield index S pk M . In addition to the point estimation, such as interval estimation are also important. In this paper we derived explicit forms of the cumulative distribution function and the probability density function of the estimated index S pk M . We developed a practical procedure and formula to provide practitioners an efficient tool for interval estimation on the yield index S pk M . An application example is illustrated. The procedure and formula are effective and easy to used, and should be expectant for in-plant applications.

After finding the significance of effective objective management and communication by reviewing previous studies on the insufficient cooperation in projects undertaken by industries, universities and government-supported research institute collaborative system, We studied how to achieve successful implementation of massive research and development projects requiring collaboration among industries, universities and government-supported research institute. We have set up an engineering process innovation model to be deemed most adequately for all practical purposes, relying on the theoretical studies on the merits and analysis of the effect of the information system based on Milestone management, Work Breakdown Structures and Web, which is known to be effective for research project (schedule) management and the objective management, and implemented a real-world web-based project (objective) management system. After a review of various R&D Project Schedule management mothods, we found that this information system was very compatible with project objective management. This project (objective) management information system has adopted a web-based approach so that geographically distant organizations having different cultures may effectively and efficiently carry out research and development projects, getting together in cyber-space and sharing information, and been equipped with an Early Warning Subsystem to allow for pre-analysis and timely response to potential problems arising over the course of the project. The system also contains an Executive Information System that in real time, automatically provides the management information required by managers with the rate of project progress (achievement, fulfillment and delay). Generated documents are also registered as reports, which are compatible with HWP documents and Microsoft Word documents through XML conversion. Lastly, actual progress may be cross-checked through both on-line objective management on the web-based
