In recent years many companies have faced with significant environmental changes. To cope with these changes, companies have shown considerable interest and commitment to innovation, In their quest for superior performance, these companies have explored different types and sources of innovation. This study examines how competitive strategy influences companies' emphasis on different innovation types (product, administrative. and process) and sources (incubative, acquisitive and imitative). This study suggests that different strategies are associated with distinct patterns of innovation types and sources. Further, the fit between competitive strategies and innovation types and sources is associated with superior company performance. Based on this concept this study suggests several hypotheses. These hypotheses, if supported by empirical study, will be very useful to the company to improve financial performance.

For improvement in productivity and weld quality, weld seam tracking and welding parameter control are very essential in the welding of a structure which can not be cxactly fit-up due to mismatch, discontinous gap, deflection, etc.. In this study, an automatic weld seam tracking system is developed for I-butt joint structure, and the system consists of XYZ working table, vision sensor and user interface program. In the developed vision sensor system, an image projection algorithm for weld-line detection and an adaptive current control algorithm for gap variation were implemented. The user interface program developed in this study by basing on the objct oriented concept could provide very convenient way to utilize the tracking system with the pull-down menu driven structure. The developed system showed a good seam tracking and weld quality control capability corresponding to deflected weld lines and gap variations.

Since information technologies have become critical to business success as a tool for organizational Innovation, successful implementation of IT Innovation is viewed as one of the most crucial tasks for many organizations. This paper examines the fit between the relevant variables and the implementation types and its impact on the success of implementation. We clarify the concept of IT innovation by distinguishing between IT innovation object and IT innovation process. Four types of IT innovation implementation were classified according to the dimensions of implementation scope and implementation pace. We developed a set of relevant prepositions and examined them through multiple case studios following the Yin's case study methodology.

The concept of IPv6 stateless address autoconfiguration lends itself easily to mobile ad hoc networks. However, the Neighbor Discovery protocol (NDP)-based mechanism described in [1] does not fit well for the multi-link environments in the mobile ad hoc network. In this document, we extend the current SAA mechanism to be suitable for mobile ad hoc networks.

This study is about implementing an job matching web service system based on the Job seeker's company assessment model proposed by the researchers. Basically, the Job seekers' company assessment model is based on the concept that each job seeker can evaluate the recruitment company candidates using job seekers's own major consideration factors. Using the implemented information system, each job seeker's main considerations in job searching process are evaluated and stored and compared to those of other job seekers' or groups' characterized by sex, job experience residential area and etc. by finding out and listing up the companies in the order of the preference of job seeker own or belonging groups, job seekers can be helped to find suitable companies which fit well to themselves.

Despite rapid social changes, there have been little distinctive or fast shifts in living space, and the kind of housing design that could address the diverse need of residents is required. In the future, complex trend that is built on a mix and match of different sorts of styles is expected to be in vogue. The introduction of natural elements and ornamental factors such as books, antiques and art works into living spaces that are artificial things is expected to contribute to helping people lead a richer and Individual life. This study attempted to present a housing design by instilling culture in an existing living space and making it fit into a new lifestyle. After the position of natural and ornamental components was fixed, a contemporary modern living space was designed, for which art works would become necessary and sufficient conditions. A plane figure of the new living space was offered, and then detailed design for each part was provided. Finally, a finalized design pattern that was suitable for the selected concept was presented.

Nonparametric Bayesian methods have seen rapid and sustained growth over the past 25 years. We present a gentle introduction to the methods, motivating the methods through the twin perspectives of consistency and false consistency. We then step through the various constructions of the Dirichlet process, outline a number of the basic properties of this process and move on to the mixture of Dirichlet processes model, including a quick discussion of the computational methods used to fit the model. We touch on the main philosophies for nonparametric Bayesian data analysis and then reanalyze a famous data set. The reanalysis illustrates the concept of admissibility through a novel perturbation of the problem and data, showing the benefit of shrinkage estimation and the much greater benefit of nonparametric Bayesian modelling. We conclude with a too-brief survey of fancier nonparametric Bayesian methods.

The concept of an "intelligent building" received significant attention from academic, industry and standard development organizations when technically termed a building management system (BMS). Wireless sensor networks (WSNs) and their recent development enhanced monitoring and control applications for the building's areas. This paper surveys and analyzes advantages of the main current and emerging approaches that may be fit for BMS. Specifically, we discuss challenges including interoperability, integration, overhead, and bandwidth limitation of WSNs in BMS. Based on analyses, we highlight the advantages of an IP-based and RESTful architecture approach as the most suitable solution for BMS using WSNs (BMS-WSN). The paper also describes our future direction and design for BMS-WSN based on these advantages. The purpose is to enable interaction of users with BMS-WSN in the same way as with any website while ensuring energy efficiency. A test-bed implementation and evaluation of a BMS application is also introduced in this paper to demonstrate the feasibility and benefits of IP-based and RESTful architecture for BMS.

Entrepreneurship is a creation of new combinations of goods and services. Today, every aspect of business operations has been changing, which we call development. The conventional business included production and manufacturing of goods and serving things the customer needed. Today, the business has changed form so that the demands of customers are shaped by the good or service which has been created by the businesses. Entrepreneurship in Mongolia is not a new concept but nowadays the number of entrepreneurs in Mongolia has grown sharply. Mongolia was a nomadic culture during its history and is probably the only nomadic culture left in the world today. Mongolian herders are the largest and the most powerful representation of successful entrepreneurs in Mongolia. Another practice of herders in the world are in Australia. Along with a comparison of the policy and government support system of Australia, this study intends to assess how 6 factors of the entrepreneurial ecosystem fit herders in Mongolia. As a result of this assessment, we propose policy to support the entrepreneurial mechanism of herders and identify cultural factors which support the existence of herding.

This paper provides a new estimation equation based on the concept of a minimum distance between the empirical and theoretical distribution functions under the most widely used progressive Type-II censoring scheme. For illustrative purposes, simulated and real datasets from a three-parameter Weibull distribution are analyzed. For comparison, the most popular estimation methods, the maximum likelihood and maximum product of spacings estimation methods, are developed together. In the analysis of simulated datasets, the excellence of the provided estimation method is demonstrated through the degree of the estimation failure of the likelihood-based method, and its validity is demonstrated through the mean squared errors and biases of the estimators obtained from the provided estimation equation. In the analysis of the real dataset, two types of goodness-of-fit tests are performed on whether the observed dataset has the three-parameter Weibull distribution under the progressive Type-II censoring scheme, through which the performance of the new estimation equation provided is examined.
