The Microporous Metal in the Polymer Processing - Carbon Dioxide Assisted Mould Temperature Control

In this thesis a carbon dioxide assisted cooling technique for primarily injection moulds, a part of the so called ToolVac™ moulding technology, has been studied. The cooling technique is based on the injection of liquid carbon dioxide into microporous mould steel. The study is an introductory examination focused on experimental work, of the cooling technique and the possibilities it offers. A tes

Comparison of testing clothing thermal resistance on 2 thermal manikins

Abstract in Undetermined The paper compares clothing thermal resistance of the same ensemble tested by different thermal manikins in different laboratories. It also examines the consistence of the two groups of total thermal resistance by Paired-Sample T Test method, which proves that there is no remarkable difference in testing results under the same experiment method and requirement. It is of gr

Some Like It Hot - Automating an Electric Kettle Using Palcom

In this demo we will show how devices from different vendors, using different protocols, can be combined and made to work together without detailed low-level programming by the user. The small example we have chosen uses a radio-controlled power socket from one vendor and a temperature sensor from another vendor. We use these to create a remotely controlled electric kettle, which keeps the water a

Nonlinear Taxation and Punishment

The paper analyzes nonlinear tax schedules that are identified by maximizing a welfare function represented by a weighted summation of net utilities over a set of n ≥ 3 differing individuals. It is demonstrated that some of the feasible and Pareto efficient tax schedules that satisfy self‐selection can only be identified by maximizing a welfare function of the above form if (at least) one of the i

It’s the bio-economy, stupid!

The bio-economy represents a significant shift in socio-economic, agricultural, energy and technical systems. The concept of the bio-economy – also called the bio-based economy or the knowledge-based bio-economy in Europe – can be understood as an economy where the basic building blocks for materials, chemicals and energy are derived from renewable biological resources, such as plant and animal so
