"ABSTRAKWater loss in a channel is an important component of the hydrologic budget for the design and planning of a water diversion and delivery system. Quantitative assessment of channel losses is required in the calculations of flow components of a river basin or reach and the projections of design flows at the withdrawal and delivery points of the water diversion system. In this study, hydrologic methods are employed to determine water losses along the Sheyenne River, a proposed diversion project. The hydrologic budget approach is considered the most appropriate method for the Sheyenne River and the proposed project. Long-term, monthly average, and annual channel losses and their longitudinal distributions are obtained. The estimated losses can be used as the additional discharge, compensating for the losses in the water delivery and supply system."

"ABSTRAKA comparative study is presented of several models describing steady-state heat flow through an assembly consisting of a primary surface (wall) and attached extended surface (fin). Attention is focused on the validity of four performance indicators. The work shows that the augmentation factor is the only indicator capable of correctly predicting the behavioral trends of the rate of heat flow through the assembly as the influencing physical parameters are varied."

"this aim of this research is to develop an assessment method for hazardous substance value in automotive components for supporting green manufacturing. basically, the green manufacturing focuses od reducing environmental risks and impacts of industrial activities through elimination of resource waste, pollution and use of material containing hazardous substances. in this research, the method will be used to assess the the hazardous substance contained automotive components quantitatively. based on the values, the hazard level of components could be compared relatively. this research has retrieved hazardous substances were assessed based on the hazardous materials identification system (HMIS). furthermore, the more information would be processed using a weighting method to obtain a single value. this research has assessed several automotive components by using the method as care studies. the result of assessments are brake pad 6.6, brake pad with asbetos 7.6, brake shoes with asbetos 13.2, clutch disc 9.2, and clutch disc with asbetos 8.6."

"Selecting a procurement strategy for construction projects is inherently subjective. The decision is often intuitively based on the previous experience and knowledge of the decision marker. An objective-subjective procurement selection method is proposed. The method takes into account the need to have an objective base for strategy comparison through the use of multiattribute utility technology. Allowing the desicion maker to assign importance ratings for the selection criteri also accommodates individual preferences and project specificities. The analytical hierarchical process based importance ratings assingment method improves both the objectivity and the realibility of the assessment. Application in real cases suggest positive potential use of the method. "

"ABSTRAK The aircraft gate reassignment problem occurs when the departure of an incoming aircraft is delayed or a delay occurs in a flight. If the delay is significant enough to delay the arrival of subsequent incoming aircraft at the assigned gate, the airline must revise the gate assignments to minimize extra delay times. This paper describes a genetic algorithm approach to solving the gate reassignment problem. By using a global search technique on quantified information, this genetic algorithm approach can efficiently find minimum extra delayed time solutions that are as effective or more effective than solutions generated by experienced gate managers.

"ABSTRAK The purpose of this study is to investigate the flow patterns of a falling liquid film as observed near an obstacle on a flow channel. In this report, a bend on the channel was chosen as the obstacle and the behavior of a ring-shaped swelling of the liquid film, which appears near the obstacle at a low flow rate, is considered. The Weber number at which the swelling shifts from upstream to downstream of the bend is theoretically estimated. The experimental results for the swelling behavior agree well with those of the above theory. Moreover, in order to investigate the characteristics of the stationary wave observed in the upstream side of the swelling, the wavelength and the damping rate of the amplitude were measured by the needle contact method and agree with theory."
