−Dividing wall columns, capable of reducing the energy required for the separation of ternary mixtures, were explored for the energy-efficient integration of debutanization and deisobutanization. A new practical approach to the design and optimization of dividing wall columns was used to optimize dividing wall columns. A conventional dividing wall column and a multi-effect prefractionator arran...

The phenomenal growth of the semiconductor industry has been made possible by our ability to deliver more functionality at a lower and lower cost, with a reduction in cost per function of approximately 25% per year. Technology advancements have also enabled higher performance, lower operating voltages, and associated lower power consumption. Dimensional shrinks based on 248 nm lithography led t...

A new encoding method for optimizing neural network structures is proposed. It is based on an indirect encoding method with variable length gene code. The search ability for finding an optimal solution is higher than the direct encoding methods because redundant information in gene code is reduced and the search space is also reduced. The proposed method easily operates adding and deleting hidd...

Volvo Aero Corporation takes part in a development project called Future Launchers Preparatory Program (FLPP) which aims to develop Next Generation Launchers (NGL) for future space flights. FLPP involves several projects and one these are focused on the development of the next generation rocket engines for the NGL. The environment of a rocket engine is extremely hostile, characterized by high p...

In this research, a poly (ionic liquid) functionalised silica-coated magnetic nanoparticles were synthesised for the first time and utilised as novel adsorbent simultaneous extraction of six phthalic acid esters from polyethylene terephthalate bottled drinking water samples. The was prepared by grafting (1-benzyl-3-vinyl-1 H-imidazol-3-ium chloride) onto Fe3O4nanoparticles via Cu(0)-mediated re...
