This paper describes the research and development of the two compact vision systems for real-time cell detection and manipulation in the capillary in order to apply on the "Desktop Bioplant" project which will achieve sort of cell manipulation tasks such as positioning, cutting, sizing, and so on, automatically between different interconnected modules. The first prototype vision system with sufficient magnification and image resolution has been designed to be boarded onto the PDMS chip. Design schema and preliminary experimental results of first proposed system have been also given. A second system with a commercially available small size and light-weight microscope unit has also been prototyped to be integrated under microfluidic channel. The integration of two models with Desktop Bioplant could bring a good solution to automation of the cell manipulation including nuclear transportation. While the size and weight of the total systems are decreased to provide portability and compatibility, determining the position and management of an egg-cell in a capillary has vital importance for the automation of nuclear transportation in a capillary with using micro robotics.

Indiscriminate cutting of hills in the Sylhet region has become a major environmental issue. The nature and life style of Sylhet intimately related with the hills are thus under the threat of a drastic imbalance in its ecosystem. Due to such hill cutting the mostly affected sectors of this region will be its weather and climate, geomorphology and hydrology, and the indigenous flora and fauna. As a result the frequency of natural calamities like earthquake, flash flooding etc may increase considerably. Deforestation and resulting increased soil erosion, decreased ground water recharge and deteriorated water quality might also be as consequences of such hill cutting. This paper investigates the cause and extent of the problem along with its probable impact and finally suggests actions for conservation of hills for ecological balance of the region. © Winter 2006.

Selecting optimum communication technology for a distributed workgroup such as an electric supply cooperative with a number of sub-stations is a challenge. A quantitative approach to evaluate the various communication technologies based on multicriteria is needed to select optimum communication technology. An electric cooperative in Minnesota was used for a case study and the various communication technologies used (frame relay, fiber optic etc) were investigated. Analytical Hierarchy Process for multicriterion was used to select optimum communication technologies between the sub-stations. The analysis showed that for sub-stations within 10 miles of the hub fiber optic was the most preferred form of communication technology. For distances over 10 miles satellite system was the preferred communication technology. Selection of appropriate communication technology improves the efficiency of the distributed workgroup. Substantial savings in communication costs can be achieved by optimizing the communication technology system.

We consider N-stage serial production/distribution systems with stationary demand at the most downstream stage. First, we study classical Clark-Scarf model with both average cost and discounted cost criteria. The optimal echelon base-stock levels are obtained in terms of only probabilistic distributions of leadtime demand. This analysis yields a novel approach for developing bounds and simple heuristics for optimal echelon base-stock polices. In addition to deriving known bounds, we develop several new upper bounds for both average cost and discounted cost models. Second and more important, we extend this idea to a more general model with two transportation modes between stages: the regular and expedited shippings (Lawson and Porteus (2000)). The optimal inventory policy for this system is known to be echelon base-stock policy, which can be computed through minimizing 2N nested convex functions recursively. We again develop simple newsvendor type of lower and upper bounds for the optimal control parameters, as well as a simple near optimal heuristic. Extensive numerical results show that the heuristics for both models perform well. The bounds and heuristic enhance the accessibility and implementability of the optimal policies in supply chains with single and dual transportation modes.

A report published by the National Academy of engineering entitled "Educating the Engineer of 2020: Adapting engineering Education to the New Century", has identified the necessity to instill leadership and management skills in future engineering graduates. Therefore, the need to teach leadership and management skills within engineering programs is becoming more prevalent. Currently, the majority of engineers that graduate with a bachelor degree have never worked on developing these skills during their academic programs. Considering the gap in covering leadership and management topics in engineering Education, curriculum reform is needed to adequately prepare students. Thus, this paper discusses the development of a minor program of specialty in engineering Leadership & management that can be pursued by all engineering and computer science majors while completing a BS degree. © American Society for engineering Education, 2006.

We consider a logistics network where a single warehouse distributes a single item to multiple retailers. Retailers in the network participate in a vendor managed inventory (VMI) program with the warehouse, where the warehouse is responsible for tracking and replenishing the inventory at various retailer locations. The information update occurs every time a vehicle reaches a location and the decision on the delivery quantity and the next location to visit is made. For a small increase of locations in the network, the state space for the solution increases exponentially, making this problem NP-hard. Thus, we propose a solution methodology where in the size of the state space is reduced at each stage. In this work, we use simulation to develop the framework for the real-time control and management of inventory and routing decisions, given this scenario

Project schedule management using a fuzzy activity network considering resource and environmental factors

引用

Journal of Japan Industrial management Association 2006年第4期57卷 261-271页

作者： Long, Luong Duc Ohsato, Ario Graduate School of Engineering Nagaoka University of Technology Japan Department of Management and Information Systems Science Nagaoka University of Technology Japan

A project is always performed in an environment influenced by resource and environment factors such as equipment, weather, labor skill, materials delivery, management quality and so on. Since these factors affect various activities on the same path in an activity network, activity durations tend to vary together. The variation of these durations affect the path duration and/or the project duration. This paper introduces a new method that incorporates these factors in a fuzzy activity network and provides factor sensitivity information to support efficient project schedule management. This method uses a triangular fuzzy number for the activity duration, and uses the spread of the triangular fuzzy number for the variation in the estimation of the activity duration. Based on the qualitative estimations of the sensitivity of each activity to each factor, the variation in activity duration is distributed to several factor variations (f-variation). Each f-variation is then broken down into more variations based on factor conditions (c-variations), with each c-variation corresponding to a factor condition such as better-than-expected, expected, or worse-than-expected. The effects of resource and environment factors are captured using c-variations under the same factor conditions to compute path and project durations. The proposed method makes it possible to improve the estimation of the path and project durations. The sensitivity of paths to factors can be searched and effectively used to improve project schedule management. Finally, an example is demonstrated, and the results are compared with other methods.

Canadian Conference on Electrical and Computer engineering (CCECE)

作者： Anas N. AbuLaban Ghassan Z. Qadah Engineering Systems Management Program American University of Sharjah Sharjah UAE Computer Engineering Department American University of Sharjah Sharjah UAE

An online auction is simply defined as a virtual marketplace hosted on the Internet to match buyers and sellers of goods around the globe regardless of the physical limitations of traditional auctions such as geography, presence, time, and space. Online auctions operate different protocols including English, Dutch, First-Price Sealed Bid and Vickrey with different properties for each one of these protocols. This paper reviews the different types of auctions and the strategies proposed in support of buyers and sellers participating in these auctions. Seller strategies for auctions that adopt protocols other than English are then presented. A scheme that integrates a number of strategies suitable for one of the auction types, namely the Dutch auction, is then developed and discussed

This paper presents the University of South Florida's novel and multi-faceted approach to integrating interdisciplinary graduate research and education with an institutional diversity initiative. Beginning with the NSF Integrative graduate Education Research and Trainee (IGERT) program, USF has developed the infrastructure for interdisciplinary research-training, while focusing on minority graduate recruitment. IGERT provides students with significant financial support to explore interdisciplinary research areas. The program requires a team of advisors from distinct disciplines to co-advise and supervise graduate research. This approach has also been successfully applied with the minority-focused NSF Florida Georgia Louis Stokes Alliance for Minority Participation (FGLSAMP) Bridge to the Doctorate program. The successes have led to certification of mentors in all departments/disciplines at USF's Colleges of engineering and Marine Science under the Alfred P. Sloan Foundations' minority PhD fellowship program. © American Society for engineering Education, 2006.

This paper presents a new methodology for screening measured data from buildings where heating, cooling, and electricity consumption are separately recorded. It defines energy balance load (EBL) as the difference between the heating requirements plus the electric gains in the building and the cooling coil loads. It then applies first law energy balance in conjunction with the concepts of analytical redundancy, trend checking, sensitivity, and uncertainty analysis to develop a methodology using measured values of E BL to identify bad data. This paper is the first part of a two-part series;it presents the theoretical basis for the methodology and illustrates its use on samples of measured building data. In part two, a program that was created to automatically pre-screen the measured building energy consumption data by utilizing EBL methodology and case studies will be introduced. © 2006 ASHRAE.
