Conducting psychophysiological experiments that measure how players experience digital games not only allows investigating the effects digital games have on players, it also gives game developers a tool to validate game design. In order to develop digital games rapidly that can be used as stimuli in psychophysiological experiments, a coherent and flexible development environment is required. A ...

Introduction Both health information technology (HIT) and the payment card industry (PCI) involve the exchange and management of sensitive, protected information. Compared to the PCI, HIT could consider protected health information (PHI) more sensitive than PCI cardholder data. If cardholder data is breached in the PCI, payment card companies may then remove fraudulent charges from the customer...

In the past few years, the use of smartphones has increased exponentially, and so have the capabilities of such devices. Together with an increase in raw processing power, modern smartphones are equipped with a wide variety of sensors and expose an extensive set of API (Accessible Programming Interface). These capabilities allow us to extract a wide spectrum of data that ranges from information...

A “3D photo-logging system,” a new method for recording archaeological sites, was developed. The prototype system consists of several servers running on a single machine and logging units composed of a camera phone equipped with a motion sensor attached to the mobile phone and a GPS sensor, and a notebook PC for logging the position and orientation of the camera phone. Using the 3D photo-loggin...

In this paper, we propose a new, efficient logging protocol, called lazy logging, and a fast crash recovery protocol, called the prefetch-based crash recovery (PCR), for software distributed shared memory (SDSM). Our lazy logging protocol minimizes failure-free overhead by logging only data indispensable for correct recovery, while our PCR protocol reduces the recovery time by prefetching data ...

This paper explores the widely accepted view thatWal-Mart causes significant harm to the traditional, small ‘‘mom and pop’’ business sector of the U.S. economy. We present the first rigorous econometric investigation of this issue by examining the rate of self-employment and the number of small employer establishments using both time series and cross-sectional data. We also examine alternative ...

Association rules mining is one of the most successfully applied data mining methods in today’s business settings (e.g. Amazon or Netflix recommendations to customers). Qualified association rules mining is an extension of the association rules data mining method, that uncovers previously unknown correlations that only manifest themselves under certain circumstances (e.g. on a particular day of...

porosity is one of the fundamental petrophysical properties that should be evaluated for hydrocarbon bearing reservoirs. it is a vital factor in precise understanding of reservoir quality in a hydrocarbon field. log data are exceedingly crucial information in petroleum industries, for many of hydrocarbon parameters are obtained by virtue of petrophysical data. there are three main petrophysical...

Selective logging is one of the most common forms of forest use in the tropics. Although the effects of selective logging on biodiversity have been widely studied, there is little agreement on the relationship between life-history traits and tolerance to logging. In this study, we assessed how species traits and logging practices combine to determine species responses to selective logging, base...
