Oversaturation of highways occurs due to their inadequate assessment and design. In this paper, we propose both a mathematical queuing model Discrete-Event Simulation (DES) framework based on Newell’s triangular flow-density relationship for the performance analysis multi-lane highway section. The proposed is finite capacity system, which captures an increase in flow with vehicle density up sec...
We consider the problem of obtaining locally D-optimal designs for factorial experiments with qualitative factors at two levels each with binary response. Our focus is primarily on the 2 experiment. In this paper, we derive analytic results for some special cases and indicate how to handle the general case. The performance of the uniform design in examined and we show that this design is highly...
a chromium electroplating bath with the ability to produce homogenous mist was used to evaluate parameters influencing hexavalent chromium (cr+6) mist sampling methods. the results of 48 cr+6mist samples collected using the u.s. national institute for occupational safety and health method 7600showed that cr+6concentration was higher: (1) for sampling by closed-face filter cassettes than for sam...
