In this lecture we examine “players machine” games, where each player chooses a machine to place her job at. We look at a global optimum function. We basically deal with two models: pure, where the players choose a deterministic strategy, and mixed, where the players choose a stochastic strategy (i.e., each chooses a probability distribution over machines). We farther examine different types of...

Speed bumps, as traffic calming devices, have been extensively used to reduce traffic speed on local streets. This study represents a unique application of experimental design methodology where the effects of some controllable factors in determining the best location for installing speed bumps before stop points (e.g. entry gates, road junctions) were investigated. Through Classical Design of E...

A passive false twist unit (spiral) has been developed to assist with the handling lowstrength slivers on a high speed-spinning machine with a high-speed feed. In the first trial, a falsetwist simulator device was constructed to determine whether the passive false twist unit can be usedon high speed feeding with different can distance from the feeding device. In the second trial, theeffects of ...

The emergence of wind turbine systems for electric power generation can help satisfy the growing global demand. To maximize wind energy captured in variable speed wind turbines at low to medium wind speeds, a robust control strategy is presented. The proposed strategy simultaneously controls the blade pitch and tip speed ratio, via the rotor angular speed, to an optimum point at which the effic...

We approximate a wind turbine using the Actuator Disc methodology with loading for an optimum Glauert rotor, and vary blade length and tip speed ratio, to determine base flows for linear stability computations at a Reynolds number of 100. Results from such computations suggest that the least stable mode is axisymmetric and insensitive to changes in tip speed operation, suggesting that the stabi...

It is essential to control VDD and VTH for low-power, high-speed CMOS design. In this paper, it is shown that these two parameters can be controlled by designers as objectives of design optimization to find better trade-offs between power and speed. Quantitative analysis of trade-offs between power and speed is presented. Some of the popular circuit techniques and design examples to control VDD...

This paper presents the ultrahigh speed microrobot actuation for cell manipulations in a microfluidic chip. The Ni and Si composite fabrication was employed to form the optimum riblet shape to reduce fluid friction on the microrobot by anisotropic Si wet etching and deep reactive ion etching. The evaluation experiments show the effectiveness of the riblet surface, especially in the case of high...

Movements of six basking sharks (4.0-6.5 m total body length, L(T)) swimming at the surface were tracked and horizontal velocities determined. Sharks were tracked for between 1.8 and 55 min with between 4 and 21 mean speed determinations per shark track. The mean filter-feeding swimming speed was 0.85 m s(-1) (+/-0.05 S.E., n=49 determinations) compared to the non-feeding (cruising) mean speed ...

Efficiently routing in a dynamic network is a important problem in ad hoc network according to development of personal data assistant (PDA) and wireless network equipment. However conventional routing algorithm is difficult to apply to dynamic topology network. Q-Routing, DRQ-Routing and Ants-Routing which are based on reinforcement learning technique are proposed. But convergence speed and rou...

The effects and influences of various operational parameters on the efficiency of mixer-settlers are thoroughly studied in this paper. One of the most important factors in designing a mixer-settler is to obtain an optimum operational extraction and overall efficiency. These two factors are dependent on various parameters such as impeller shape, size and speed of impeller, baffle size, residence...
