based on two integration steps, an optimization framework is proposed in this work for the synthesis and design of complex distillation sequence. the first step is to employ heat integration in sequence and reduce the heat consumption and total annual cost of the process. the second one is to increase the exergetic efficiency of sequence by generating power in implemented expanders in sequence....

In many global optimization problems motivated by engineering applications, the number of function evaluations is severely limited by time or cost. To ensure that each of these evaluations contributes to the localization of good candidates for the role of global minimizer, a sequential choice of evaluation points is usually carried out. In particular, when Kriging is used to interpolate past ev...

Accurate predictive simulations of human gait rely on optimisation criteria to solve the system’s redundancy. Defining such is challenging, as objectives driving optimization are unclear. This study evaluated how minimising various physiologically-based (i.e., cost transport, muscle activity, head stability, foot–ground impact, and knee ligament use) affects predicted gait, developed a combined...

In this paper, we study the licensing of cost-reducing innovations in a duopoly under supply function competition. We show that innovator prefers fixed-fee to no if its cost advantage is not extremely large. Moreover, small, and mixed revenue-royalty licensing. This second result arises only because our assumption functions are quadratic. linear royalty payments per unit output, strictly also m...

We studied the phononic heat transfer through an atomic dielectric wire with both infinite and finite lengths by using a model Hamiltonian approach. At low temperature under ballistic transport, the thermal conductance contributed by each phonon branch of a uniform and harmonic chain cannot exceed the well-known value which depends linearly on temperature but is material independent. We predict...

The 1:1:2 resonant elastic pendulum is a simple classical system that displays the phenomenon known as Hamiltonian monodromy. With suitable initial conditions, the system oscillates between nearly pure springing and nearly pure elliptical-swinging motions, with sequential major axes displaying a stepwise precession. The physical consequence of monodromy is that this stepwise precession is given...

Multi-spectral recording systems are used in numerous applications ranging from quality assurance over biometrics to remote sensing. This paper reports on the feasibility of a LED-based multi-spectral imaging system where the spectral characteristics of the illumination is changed by activating different LEDs. The multi-spectral images are captured by a cost-efficient CCD camera. We focus here ...

The objective of this paper is to investigate the use of cross-company and within-company cost estimation model for Web projects. The study analysis method we used was a forward, stepwise regression of web project development effort with independent variables that were used for on-line web application price quotations. Model cross-validation used two approaches: one-fold cross validation and a ...
