Procrastination became increasingly prevalent among students in recent years. However, little research was found that directly compares academic procrastination across different academic grade levels. The present study used a self-regulated learning perspective to compare procrastination types and associated motivation between undergraduate and graduate students. Sixty-six undergraduate a...

We propose an automated solution for computing the number of simultaneous active speakers within a timeframe. The method is studied in parallel with a perception experiment realized with the help of 28 volunteers that were asked to detect how many speakers talk simultaneously in several recordings with variable length. For this study we focus on how listening time and the usage of familiar voic...

Orientation, Navigation and Mobility are perhaps three of the most important aspects of ordinary human life. Most aspects of the dissemination of information to aid navigation and cues for active mobility are passed to humans via the most complex sensory system, the vision system. This visual information forms the basis for most navigational tasks and so with impaired vision an individual is at...

Two predominant areas of ongoing transport electrification are the uptake electric vehicles (EVs) in personal transportation and electrically powered trains for mass - both significantly increase demand stresses on power grid. In this research, a novel V2G application to support rail is proposed. A local network can reduce peak grid arising from electrified traffic enable brake energy recovery ...

There is provided a new software solution for multiple data sources integration at modern enterprises with distributed organizational structure. Open Services Provider (OSP) is a platform powered by SEC "Open code" that allows developing situational centers for decision making support based on Big Data analysis and visualization. The paper describes a problem of management of modern distributed...

Current available data do not seem to support the strategy for carotid endarterectomy prior to surgical intervention in patients with asymptomatic carotid stenosis. However, in patients with coronary artery disease, synchronous carotid endarterectomy and coronary artery bypass grafting should be considered where there is a proven surgical risk of <3% with unilateral asymptomatic stenosis >60% o...

Searching for a better efficiency, an auxiliary energy system for electric vehicles was designed, implemented and tested. The system, composed of an ultracapacitor bank and a buckboost converter, was installed in an electric vehicle, which is powered by a lead-acid battery pack and a 54 kW brushless DC motor. Two control strategies where developed: one based on heuristics and the other based on...

This study was designed to compare the ultraportable mechanically powered Smart Negative Pressure (SNaP) Wound Care System (Spiracur, Sunnyvale, CA) with the electrically powered Vacuum-Assisted Closure (VAC) Therapy System (Kinetic Concepts, Inc. [KCI], San Antonio, TX) in a multicenter, comparative efficacy, noninferiority-powered, randomized controlled trial. We enrolled 132 people with noni...
