Nowadays, there is worldwide interest in diversifying energy supply. In this regard, biomass is the best possible renewable organic substitute for fossil fuels. In particular, the energy content of very wet biomass, recovered with appropriate technology, could potentially be used for power generation. In addition to power generation, this...

Encapsulation-based self-healing technology is an effective method for healing the crack-deteriorated cementitious material. Encapsulation-based self-healing initiates by crack occurrence and progresses by chemical reaction of released self-healing agents in the cracks, which are contained in capsules. In this paper, a review has been...

Deepwater drillships are nowadays capable of drilling to oil in water depths up to 4000m and reservoirs at 12000 m depth and greater. Active Heave Compensation at these large drilling depths and station keeping with the Dynamic Positioning system leads to large fluctuations in the electrical power system. The electrical power is now directly...

The flow motions in the turbulent boundary layer between water and a rowing boat initiate a turbulent skin friction. Reducing this skin friction results in better rowing performances. A Taylor-Couette (TC) facility was used to verify the power losses due to velocity fluctuations P<sub>V′</sub> in relation to the total power, as a function of...

A simplified model is established to estimate the jet exit density variation of a plasma synthetic jet actuator (PSJA) driven by a capacitive arc discharge. This model, in conjunction with phase-locked planar particle imaging velocimetry (PIV) measurements, enables the calculation of jet mechanical energy for different operating conditions....

A method to quantify the efficiency of the first two operational stages of a nanosecond dielectric barrier discharge (ns-DBD) plasma actuator is proposed. The method is based on the independent measurements of the energy of electrical pulses and the useful part of the energy which heats up the gas in the discharge region. Energy input is...

A mitad is a type of stove used to prepare traditional Ethiopian flatbread called injera. Current electrical mitads are energy inefficient and account for over 8% of Ethiopia’s national electricity consumption. The Magic Mitad bakes high quality injeras and uses up to 45% less electricity. This will help bakeries and households to cut costs and...

In this thesis both Wake Ingestion (WI) and Boundary Layer Ingestion (BLI) configurations have been investigated and analyzed with respect to their application to aircraft design. WI and BLI in the context used here means positioning the engine such that it ingests boundary layer fluid for the purpose of saving shaft-power. This research...

The goal of this study was to find an efficient method of energy transmission for application in an anthropomorphic underactuated body-powered (BP) prosthetic hand. A pulley-cable finger and a hydraulic cylinder finger were designed and tested to compare the pulley-cable transmission principle with the hydraulic cylinder transmission principle....

Research on performance assessment of railway networks and companies has been stimulated by the European policy of deregulation of transport markets, the opening of national railway networks and markets to new entrants and separation of infrastructure and train operation. Recent international benchmarking studies of railways based on statistical...

Computer Aided Architectural Design (CAAD) decisions and judgments have been at the heart of architectural design practice. Despite the increasing popularity of computer aided design applications, measuring the decision making of designers empirically remains elusive. Past research claiming usefulness of the CAD has relied largely on anecdotal...

In this paper we examine the strategies used in 3D modeling for their efficiency. Our study explores the underlying cognitive process that drives design thinking as well the choice of strategies for using specific features in a given CAD software. We take a cognitive task analysis approach to examine our question. Of a total sample of 19...

Current articulating electric and body-powered hands have a lower pinch force (15–34 N) than electric hands with stiff fingers (55–100 N). The cosmetic glove, which covers a hand prosthesis, negatively affects the mechanical efficiency of a prosthesis. The goal of this study is to mechanically compare polyvinylchloride (PVC) and silicone...

Replacement of a missing hand by an artificial alternative remains one of the biggest challenges in rehabilitation. Although many different terminal devices are available, around 27% of the amputees does not actively use their device and 20% totally refrains from wearing it. There are various reasons for prosthesis abandonment, e.g. wearing...
