Nonpremixed jet flames of dimethyl ether (DME) were studied both experimentally and theoretically to investigate flame liftoff near unity Schmidt number. It was found experimentally that although the DME nonpremixed flames have a Schmidt number larger than unity it cannot be lifted directly by increasing the flow rate. Lifted flames can only be established by igniting the mixture in a narrow re...

Technology Enhanced Learning (TEL) is a very broad and increasingly mature research field. It encompasses a variety of research topics, ranging from the study of different pedagogical approaches, teaching techniques, and strategies for online learning to the application of advanced technologies in educational settings (e.g., different kinds of mobile devices, sensors, and sensor networks that p...

In this study, NiTi thin films were deposited on the glass and NaCl substrates by means of magnetron sputtering method. The influence of aging temperature, over the range 300-500 oC, on phase transformation and mechanical properties of the sputtered NiTi thin films were studied by differential scanning calorimetry (DSC) and nano-indentation assay, respectively. The DSC curves showed that the ag...

cotton is one of the most important crops in the world and increasing cotton yield is the main goal in the cotton industry. one important factor for crop improvement is increasing produced fibers by each developing seed. it is very interesting to manipulate fiber properties such as length, micronaire, color and strength which necessitate cotton ovule culture.  ovule culture is used as a tool to...

the aim of this study is to evaluate how far lempel-ziv complexity (lzc) of the binary symbolic sequences resulting from static or dynamic transformation (partitioning first-order difference) of the short-term electrocardiogram (ecg) signals (only 2 seconds duration) has the  potential in discriminating normal and ventricular tachycardia/ventricular fibrillation (vt/vf) subjects. the statistica...

In recent years, games and learning researchers have increasingly become interested in the "affinity spaces" (Gee, 2004) around popular videogames, identifying them as instructional spaces (Squire and Giovanetto, 2008) and contexts in which sophisticated reasoning practices are enacted (Steinkuehler and Duncan, 2008). However, the motivation for participation in these communities as well as the...

Electroconvulsive therapy (EeT) produces memory impairment which may be modified (Valentine et. al., 1968; Squire, 1977; Weiner. 1979) by a choice of stimulus electrode placement (bilateral liS. unilateral nondominant) or electrical stimulus wave form (sinusoidal liS. brief-pulse). Regarding electrical stimulus wave form, it has been suggested that more amnesia may follow sinu­ soidal than brie...

In this chapter we present the formal language, stochastic process algebra (STOPA), to specify cognitive systems. In addition to the usual characteristics of these formalisms, this language features the possibility of including stochastic time. This kind of time is useful to represent systems where the delays are not controlled by fixed amounts of time, but are given by probability distribution...

A systematic review of published English-language articles on handoffs is conducted (1987 to June 4, 2008). Forty-six articles describing 24 handoff mnemonics are identified by trained reviewers. The majority (82.6%) have been published in the last 3 years (2006-2008), and SBAR (Situation, Background, Assessment, Recommendation) is the most frequently cited mnemonic (69.6%). Of 7 handoff resear...
