Slow sand filters (SSF) are a simple water treatment technology providing an important alternative to conventional drinking treatment. SSF extensive in terms of carbon cost and chemical use but require large land area complex operate, as periodic cleaning is required prevent filter clogging. Therefore, redundant beds enable production occur during long downtimes. Underwater skimming (UWS) innov...

This paper describes how four independent navigational aids can be smoothly integrated in a unified graphical user interface. Our aim is to improve user performance in most web related tasks through integration of navigational aids. The navigational aids considered are (1) a short term history (the six last visited pages), (2) a personal “BestOf”, (the six most visited web pages), (3) an area o...

A chute is characterized by a steep bed slope associated with torrential flow. This chute flow may be either smooth or stepped. The flow conditions in stepped channels are classified as nappe flow, transition flow and skimming flow. In this paper, hydraulic characteristics of flow regimes on the stepped channels are presented systematically under a wide range of discharge, channel slope and ste...

"Big data" and statistical techniques to score potential transactions have transformed insurance and credit markets. In this paper, we observe that these widely-used statistical scores summarize a much richer heterogeneity, and may be endogenous to the context in which they get applied. We demonstrate this point empirically using data from Medicare Part D, showing that risk scores confound unde...

In milk processing, special emphasis is directed to fostering the taste and healthy values of goat milk. Therapeutic properties of goat milk are very well known. Comparison of cow and goat milk at the level of chemical composition suggests significant differences in their physical and chemical characteristics. Smaller diameter of fat globules (natural homogeneity), high portion of essential ami...

Using multimedia documents for learning puts specific demands on the user interface. Users want to be able to quickly skim audio-visual data in order to locate relevant information, skip parts of minor interest, reset replay to interesting positions, etc. In this paper we propose a new interface design which extends common media player interfaces by offering a new way for interactive, synchroni...

The first arthropod trackways are described from the Middle Cambrian Burgess Shale Formation of Canada. Trace fossils, including trackways, provide a rich source of biological and ecological information, including direct evidence of behaviour not commonly available from body fossils alone. The discovery of large arthropod trackways is unique for Burgess Shale-type deposits. Trackway dimensions ...

The growing demands placed upon the field of computer vision have renewed the focus on alternative visual scene representations and processing paradigms. Silicon retinea provide an alternative means of imaging the visual environment, and produce frame-free spatio-temporal data. This paper presents an investigation into event-based digit classification using N-MNIST, a neuromorphic dataset creat...

Video adaptation uses various spatio-temporal adaptation techniques to transform video content in order to satisfy diverse resource constraints and user preferences. To explore systematic solutions, we present a new conceptual framework to model content, adaptation processes, utility, resources, and relations among them. The key to the framework is definition of the notion of utility and the fo...
