Film cooling has dramatically contributed to the performance improvement of gas turbines, as it is a very effective technique for turbines. Large eddy simulation (LES) began be used in study film 20 years ago, and meaningful results have been found, but not yet intensively reviewed. In this review paper, we analyze introduce about 70 papers published on LES over past years. Numerical instabilit...

Following the footsteps of SemEval-2014 Task 4 (Pontiki et al., 2014), SemEval-2015 too had a task dedicated to aspect-level sentiment analysis (Pontiki et al., 2015), which saw participation from over 25 teams. In Aspectbased Sentiment Analysis, the aim is to identify the aspects of entities and the sentiment expressed for each aspect. In this paper, we present a detailed description of our sy...

We have investigated the crystallization kinetics of Cu50Zr50 metallic glass thin films using nanocalorimetry. The crystallization process is growth-controlled during heating and nucleation-controlled during cooling, resulting in different critical heating and cooling rates to suppress crystallization. Measurements over a wide range of scanning rates (13 K/s to 21,000 K/s) reveal that crystalli...

Heat and mass transfer between air and falling solution film in a cross flow configuration is investigated. Effects of addition of Cu-ultrafine particles in enhancing heat and mass transfer process are also examined. A parametric study is employed to investigate the effects of pertinent controlling parameters on dehumidification and cooling processes and their subsequent optimization. It is fou...

A low cross-polarization slot array antenna in the narrow wall of ridge waveguide is presented. A non-angled slot which is created in the narrow wall of the ridge waveguide is considered to be used as radiating resonant slot. The normalized resistance and normalized reactance curves are presented for design purposes. A six element slot array waveguide antenna with ridges on its narrow wall is t...

Although focal brain cooling has distinct power on suppressing epileptic seizures, the technological and physiological feasibility for therapeutic application still remains unknown. This paper addressed the issue of technical feasibility though the development of an implantable, thermoelectricallydriven cooling device. Chronic application of the device on the seizure focus in rats significantly...
