We show how to construct the optimum superstatistical dynamical model for a given experimentally measured time series. For this purpose we generalise the superstatistics concept and study a Langevin equation with a memory kernel whose parameters fluctuate on a large time scale. It is shown how to construct a synthetic dynamical model with the same invariant density and correlation function as t...

To investigate quantitatively the effects of stirring on protein crystallization, a new stirring system which can agitate a protein solution, approximately 100 nl, by providing Hagen-Poiseuille flow has been successfully developed. In addition, this new stirring system provides flow with a well defined pattern and velocity. Using this system, hen egg-white lysozyme was crystallized in 100-200 n...

The evolution strategy with neighborhood attraction (EN) is a new combination of self-organizing maps (SOM) and evolution strategies (ES). It adapts the neighborhood relationship known from SOM to ES individuals to concentrate them around the optimum of the problem. In this paper, detailed investigations on the in uence of one of the most important EN-operators { the neighborhood attraction { w...

This work presents a numerical investigation of a vertical internally finned tube subjected to forced convection heat transfer. The governing equations were solved numerically using the control volume technique. Nusselt number, Nu, and friction factor multiplied by Reynolds number, fRe, are influenced greatly by the height and number of the radial fins. The velocity and temperature distribution...

We report an unusual case of retained metallic intraocular foreign body (IOFB) presenting with acute retinal necrosis (ARN). A healthy young man presented with signs of ARN including hypopyon, dense vitritis, and peripheral retinal necrosis following alleged history of trauma with a high-velocity projectile. After initial management of ARN with systemic antivirals, a retained metallic IOFB was ...

Using molecular dynamics calculations, we investigate the absorption of a C(60) molecule in a (10,10) nanotube either through the open end or a large defect in the tube wall as possible scenarios for the hierarchical self-assembly of (C(60))(n)@(10,10) "nano-peapods." We find the absorption through a defect to be significantly more efficient than the end-on absorption. This process occurs most ...

This paper reports on research to evaluate the application of artiicial neural networks to pump condition monitoring. Based on historical velocity vibration measurements, artiicial neural networks were developed to assess pump condition. Pumps, in general, behave like most rotating equipment and evolve or deteriorate as a function of a single variable, namely time. Such evolution forms the basi...

Regarding the node localization problems for wireless sensor network, a hybrid optimization method was proposed accordingly on differential evolution(DE) algorithm and particle swarm optimization(PSO) algorithm. Firstly, the position and velocity of the initial population were randomly generated by PSO, and the fitness function was constructed according to the mean square error of estimated and...

The present work analyses different parameters of pressure die casting to minimize the casting defects. Pressure diecasting is usually applied for casting of aluminium alloys. Good surface finish with required tolerances and dimensional accuracy can be achieved by optimization of controllable process parameters such as solidification time, molten temperature, filling time, injection pressure an...
