In electrical impedance tomography (EIT) images of the object are formed based on passive electrical properties of the interior structures. In EIT an array of electrodes is attached around the object and small alternating currents are injected via these electrodes and the resulting voltages are measured. Using di erent current injections and voltage measurements, an approximation for the spatia...

Scientific papers revolve around citations, and for many discourse level tasks one needs to know whose work is being talked about at any point in the discourse. In this paper, we introduce the scientific attribution task, which links different linguistic expressions to citations. We discuss the suitability of different evaluation metrics and evaluate our classification approach to deciding attr...

Diversifying participation in crowd work can benefit the worker and requester. Increasing numbers of older adults are online, but little is known about their awareness of or how they engage in mainstream crowd work. Through an online survey with 505 seniors, we found that most have never heard of crowd work but would be motivated to complete tasks by earning money or working on interesting or s...

Little is known of the interplay between deixis and eye movements in remote collaboration. This paper presents quantitative results from an experiment where participant pairs had to collaborate at a distance using chat tools that differed in the way messages could be enriched with spatial information from the map in the shared workspace. We studied how the availability of what we defined as an ...

1 es in the following wo er, BN classifier is the most suitable for multi-stroke symbols and per Sketch is a type of natural, simple and convenient human-computer interaction which conveys ambiguous conceptions and imperfect information. It adapts to creative activities and improves the collaboration and communication among people. With the rapidly extended application of hand-written character...

Background: Greenspace has the potential to be a vital resource for promoting healthy living for people in urban areas, offering both opportunities for physical activity and wellbeing. Much research has explored the objectively measurable factors within areas to the end of explaining the role of greenspace access in continuing health inequalities. This paper explores the subjective reasons why ...

Global advocacy campaigns increasingly highlight the negative impact of reproductive morbidity on economic productivity and development in order to justify donor investment in maternal health. Anthropological approaches nuance such narrow economic estimations of reproductive health. Drawing on ethnographic fieldwork from Burkina Faso in West Africa, this paper analyses the dynamic, and sometime...

This paper rst reviews some basic facts about electron transport in semiconductor materials. Then, it develops several macroscopic models from the diiusion approximation of the semiconductor Boltz-mann equation. The rst model to be derived is the 'Spherical Harmonics Expansion model', which consists of a parabolic equation for the energy distribution function. A second model is then deduced, kn...

deposition has been optimized for best quality at 250°C for the 250°C and 285°C processes, and at 200°C for the 200°C process [12] [13] [14]. Dry etching is used next to pattern the a-Si:H islands and open contact vias to the bottom metal. The top metal (Cr/Al based) is then thermally evaporated and patterned by wet etching. The n + a-Si:H is then cut at the backside of the a-Si:H channel by dr...

Social media are changing the way we do business and how leaders are perceived, from the shop floor to the CEO suite. But whereas the best businesses are creating comprehensive strategies in thi area, research suggests that few corporate Leaders have a social media presence--say, a Facebook or Linked in of page--and that those do don't use it strategically. Today's leaders must embrace social m...
