The ambulance driver is one of the parties that participates in helping victims. purpose this community service to optimize role drivers providing assistance emergency conditions which include evacuation, stabilization, transportation. In an effort optimize, counseling needed related emergencies often occur. implementation program carried out three stages, namely, pre-test, counseling, and post...

in this study the factors controlling the software colorimetry (photoshop), including illumination (direct and indirect), image background (white and black), camera settings (zoom, light, resolution and environmental conditions) and the conversion equations of r, g, b images to l *, a *, b *, compared with the results of the device were investigated and optimized. the results showed that the fa...

this study investigates removing ash and pyrite sulphur from bitumen by column flotation process. central composite design (ccd) of response surface methodology (rsm) was applied for modeling and optimization of the percentage of ash and pyrite sulphur removal from bitumen. the effects of five parameters namely the amounts of collector and frother agents, particle size, wash water rate and feed...

Experiment Design – Response Surface Methodology (RSM) is used to model and to optimize the activation of Methane (C1) using Ethane (C2) as co-reactant into higher hydrocarbons, over Zn-containing zeolite catalyst. The application of this methodology in this work, allows a better understanding of the influence of the different factors; on two responses simultaneously: C1 Conversion and Aromatic...

This survey article summarizes some ideas of the two principle procedures for solving optimal control problems governed by partial differential (algebraic) equations: the indirect method or first-optimize-then-discretize approach based on first-order necessary conditions, and the direct method or first-discretize-then-optimize approach based on non-linear programming software. The focus of this...

Two liter bottle rockets made from recycled soda bottles are often used in high school science classes and in introductory college courses. Typically, it is often more challenging to shoot bottle rockets for distance instead of shooting them straight up and measuring altitude, as is often done. Using a device made from pipe and wood to launch bottle rockets and control the launch angle creates ...
