Abstract:

The development and fabrication injection of moulding tools is complex and demands highly skilled personal. The research aim is to study the effect of surface roughness on mould filling and the ejection of parts for amorphous and semicrystalline polymers. This study is to simulate and analyse polymers used and investigates the ejection force needed for different selected polymer resins for a series of cavity and core inserts with different surface roughnesses. Mould filling and comparison studies for polymers used also were carried out. Three common thermoplastics polymers were used for the cy

Abstract:

Polyelectrolyte hydrogels are viscoelastic electroactive polymers which respond to external physical or chemical stimuli by a reversible volume phase transition. Novel fabrication methods allow the creation of hydrogel layer composites in which each layer shows a different sensitivity (e.g. to a different stimulus). This offers new opportunities, for example, in the design of new microsensors, microactuators and microfluidic devices as well as for high-selective membranes and target-specific drug delivery systems. Since only few research groups numerically investigated the transport mechanisms

Abstract:

We compute the thermal photon production of a quark gluon plasma in thermal equilibrium at finite baryon chemical potential. We show that the photon production is equivalent to the integral of a Wightman current-current correlator. Subsequently, we present an introduction to quantum field theory at finite temperature, with emphasis on the real time formalism. Expressions for real time QCD propagators in the Keldysh basis at finite baryon chemical potential are derived in detail. In the second part, a power counting analysis is performed to determine exactly which Feynman diagrams contribute to

On a papermaking machine, fines and colloids are retained in a paper sheet.

To enhance retention, many retention aids are available, one of which is neutral polyethylene oxide (PEO) used in combination of a phenolic cofactor (CF).<br>In this work, a new model was derived in which all possible interactions were considered and assumed to

With hardness around ~40HRC, they have properties such as good polishability, good weldability, corrosion resistance and thermal conductivity. Machinability is a very important parameter in pre-hardened mold steels as it has a direct impact on the cost of the mold. In normal machining operations involving intricate or near net shapes, ma

Mathematical models of isothermal chemical systems in reactor problems and Turing's theory of morphogenesis with an application in sea-shell patterning are studied. The reaction-diffusion systems describing these models are solved numerically. First- and second-order difference schemes are developed, which are economical and reliable in comparison to classical numerical methods. The linearization process decouples the reaction-diffusion equations thereby allowing the use of different time steps for each differential equation, which may be large due to the excellent stability properties of the

Analytical arguments supported by numerical studies show that there is no phase transition as a function of the baryonic chemical potential.

Abstract:

Environmental concerns and pressures have made the pulp and paper industry move towards the recirculation of white water. These measures have led to lower volumes of water discharged by those mills recirculating water, and also to increasing problems in the mills. One of these problems is the loss of effectiveness of the PEO-cofactor retention aid systems, due to the increasing concentration of dissolved solids in the water. The results show that the presence of high surface area compounds such as fines, clay and organic compounds, like abietic acid can indeed affect the efficiency of PEO.<br>

Abstract:

The finite state projection algorithm provides modelers a new way of directly solving the chemical master equation. The algorithm utilizes the matrix exponential function, and so the algorithm’s performance suffers when it is applied to large problems. Other work has been done to reduce the size of the exponentiation through mathematical simplifications, but efficiently exponentiating a large matrix has not been explored. This work explores implementing the finite state projection algorithm on several different high-performance computing platforms as a means of efficiently calculating the matr
