A general or agent-based security system is usually constructed hierarchically and has a central manager acting as head of the whole system. However, the manager becomes a bottleneck for being connected by each client...

The notion of linear fpt-reductions has been recently used to derive strong computational lower bounds for well-known NP-hard problems. In this paper, we formally investigate the notions of W[t]-hardness and W[t]-comp...

This paper considers the decentralized dynamic programming path planning decision processes of multiple cooperating autonomous aerial vehicles (UAVs) engaged in a search of an uncertain environment. However, what sets this paper apart from previous work is that a functional approximation is used for the dynamic programming (DP) cost-to-go function, resulting in improved quality of the decisions made while retaining computationally feasibility. Some of the effects of the changes are measured by simulation analysis, and the results are presented.

Faculty from Oakland University's engineering, business and education schools are working together with Oakland's Pawley Institute to teach students about lean manufacturing using an interdisciplinary approach. The goal is to educate future employees about lean from a diverse perspective before they enter the workforce. By providing students with the knowledge and skills to use lean principles and tools to solve real world problems, these future employees will add immediate value to the companies that hire them. These Oakland University faculty members have developed an interdisciplinary course entitled "Lean Principles and Application". This elective course is taken by students enrolled in engineering, business, and human resource development degree programs. A key component of the course is a semester long project that involves analyzing the performance of a local manufacturing company and developing a plan for implementing a lean program. Interdisciplinary teams of students work on the project with company personnel

This research proposes to modernize a legacy software system by using web services as the main building blocks of the software reengineering. For this purpose, a legacy theorem proof checking and derivation tool called Bertie3 is reengineered in terms of service-oriented architecture, service-oriented componentization, and external data representation and serialization. With the web services of derivation checking engines and first-order markup languages, a minimal amount of development time can be spent working on well-known and well-developed components. More time can be spent updating the features that make the tool unique. This case study shows that modernizing a software system with web services will allow the business components of the system to be easily expanded and integrated with other application components for future demands.

This paper looks into how integrating on-line purchasing with inventory management system for distributed retail chain stores can automate and aid the process of decision-making in relation to on-line product sales and distribution. It extends the work done in [1], to include not only on-demand and automatic communication between the retail chain store's head office and point-of-sale (POS) outlets, but also to include on-line purchasing capabilities for home users. The application uses distributed databases to store information relevant to customers, products and product transactions at different geographical locations. The system is designed to facilitate the management process between the head office and the POS outlets: it aids top-level management to make the right business decisions in terms of the right products being distributed at the right location and at the right time, and also products ordered by home users to be sent by the right POS outlet, and it aids low-level employees to manage the daily business transactions of each POS outlet efficiently.

A new incremental clustering method is presented, which partitions dynamic data sets by mapping data points in high dimension space into low dimension space based on (fuzzy) cross-entropy(CE). This algorithm is divided into two parts: initial clustering process and incremental clustering process. The former calculates fuzzy cross-entropy or cross-entropy of one point relative to others and a hierachical method based on cross-entropy is used for clustering static data sets. Moreover, it has the lower time complexity. The latter assigns new points to the suitable cluster by calculating membership of data point to existed centers based on the cross-entropy measure. Experimental comparisons show the proposed method has lower time complexity than common methods in the large-scale data situations or dynamic work environments.

Changes in requirements may have a severe impact on development processes. For example, if requirements change during the course of a software development activity, it may be necessary to reschedule development activities so that the new requirements can be addressed in a timely manner. Unfortunately, current software development methods do not provide explicit means to adapt development processes with respect to changes in requirements. The paper proposes a method based on Markov decision theory, which determines the estimated optimal development schedule with respect to probabilistic product demands and resource constraints. This method is supported by a tool and applied to an industrial case.
