Their light weight, low-cost manufacturing, ease of fabrication, and the availability of inex‐ pensive flexible substrates (i.e.: papers, textiles, and plastics) make flexible electronics an ap‐ pealing candidate for the next generation of consumer electronics [2]. Moreover, recent developments in miniaturized and flexible energy storage and self-powered wireless com‐ ponents paved the road for...

Palm oil fuel ash (POFA) has previously been used as a partial cement replacement in concrete. However, limited research has been undertaken to utilize POFA in high volume in concrete. This paper presents a study on the treatment and utilization of POFA in high volume of up to 50% by weight of cement in self-consolidating high strength concrete (SCHSC). POFA was treated via heat treatment to re...

In a nutshell Flexi-curity is not only a buzz-word, but drives the policy agenda of the EU. Therefore it is important to know about what we talk when we talk about the term. What is at stake is some shift from employment protection towards social protection. In other words, some of the risk/uncertainty management linked to labour markets in an era of globalisation is to be put on broader should...

The characteristics and properties of mixtures of a borosilicate glass and ZrO2 fibres obtained from compacts isothermally sintered are presented. Three different particle sizes of glass powder and different sintering temperatures and times have been used to reveal the influence of the specific surface area and the glass matrix viscosity on sintering. The fundamental developed aspects are the s...

Non-intrusive hydroxyl radical (OH) planar laser-induced fluorescence (PLIF) measurements were obtained in configuration C of the University of Virginia supersonic combustion experiment. The combustion of hydrogen fuel injected through an unswept compression ramp into a supersonic cross-flow was imaged over a range of streamwise positions. Images were corrected for optical distortion, variation...

To carry out the investigation, a cylinder pressure model was developed based on the position of the crankshaft, engine load, engine speed, and fuel injection time. This model takes into account the maximum number of parameters involved. The accuracy of the model was verified by experimental results. The average error of the cylinder pressure, the average radical of the square of the error of t...

Using firm-level data on the sales and sourcing patterns of Japanese affiliates, this paper suggests that very little foreign direct investment (FDI) falls neatly into the standard bins of horizontal, vertical and export-platform FDI. Most affiliates import some intermediates and export some output, suggesting a pattern that might be called “networked FDI.” This suggests that the nature of FDI ...

Strict protection of organic light-emitting diodes (OLEDs) and other optoelectronic materials from direct contact with ambient moisture and oxygen is one of the major challenges in the development of flexible OLED displays and other flexible electronic devices. This problem is typically addressed by the use of polymeric substrates with multilayered barrier coatings comprising alternating organi...

This work reports on an integrated energy harvesting prototype consisting of dispenser-printed thermoelectric energy harvesting and electrochemical energy storage devices. The use of a commercially available DC-to-DC converter is explored to step-up the mV output voltage of the printed thermoelectric device to several volts for charging printable zinc-based micro-batteries. Two separate paralle...
