Gas and downhole water sink-assisted gravity drainage (GDWS-AGD) is a new process of enhanced oil recovery (EOR) in reservoirs underlain by large bottom aquifers. The capital intensive as it requires the construction dual-completed wells for production additional multiple vertical gas-injection wells. costs could be substantially reduced eliminating using triple-completed multi-functional These...

Placement of multiple dies on an MCM or high-performance VLSI substrate is a non-trivial task in which multiple criteria need to be considered simultaneously to obtain a true multi-objective optimization. Unfortunately, the exact physical attributes of a design are not known in the placement step until the entire design process is carried out. When the performance issues are considered, crossta...

SAGD (steam-assisted gravity drainage) technique is one of the most efficient thermal recovery technologies for exploiting Mackay River thin layer oil sand reservoirs. However, when making use traditional (the production and injection well are located on same axis with horizontal spacing 0 m), steam chamber development usually insufficient because high longitudinal sweep rate steam, which serio...

This paper discusses the placement of a microphone for feedforward based active noise control in a forced-air cooling system. Incorrect placement of microphones may lead to poor signal correlation that limit the ability of active noise suppression. Microphone placement can be by facilitated by direct on-line optimization of the Active Noise Control system. The feedforward based noise cancellati...

The amount of Video Surveillance Systems around the world is continuously increasing, however, the usage of these systems in not the only choice how to solve security problem in many cases. The camera placement within the observed area is one of the most relevant problems within the new Video Surveillance System design. Some potential to automate the camera placement within the particular area ...

Dynamic Partially Recon ̄guration (DPR) designs provide additional bene ̄ts compared to traditional FPGA application. However, due to the lack of support from automatic design tools in current design °ow, designers have to manually de ̄ne the dimensions and positions of Partially Recon ̄gurable Regions (PR Regions). The following ̄ne-grained placement for system modules is also limited because it ta...

This paper addresses a multi-robot optimal assembly planning problem which in essence is an augmented Travelling Salesperson Problem (TSP+). In our TSP+, both the “salesperson” (a robot with a tool) as well as the “cities” (another robot with a workpiece) move. Namely, in addition to the sequencing of tasks, further planning is required to choose where the “salesperson” should rendezvous with e...

Placement of phasor measurement units (PMUs) in power systems has often been formulated for achieving total network observability. In practice, however, the installation process is not implemented at once, but at several stages, because the number of available PMUs at each time period is restricted due to financial problems. This paper presents a novel integer linear programming framework for o...

wind power has been widely considered and utilized in recent years as one of the most promising renewable energy sources. in the current research study, aerodynamic analysis of the upwind three-bladed horizontal axis turbine is carried out using blade element momentum theory (bem), and a genetic algorithm (ga) is applied as an optimization method. output power generation is considered as an obj...
