The Help America Vote Act mandated that all polling places have an accessible method of voting that provides privacy and independence. Direct Recording Electronic voting machines (DREs) have been assumed to be the solution to providing accessible voting, but there is reason to believe extant systems do not adequately serve this goal (Runyan, 2007). This study is a first step in addressing the l...

In the paper frequency domain Super−Resolution algorithm with enhanced reconstruction stage is presented. The Fourier transform properties of relocated images are used to easy estimation of rotation and translation, as well as artifacts caused by subsampling. Previously, the bicubic interpolation has been employed in the reconstruction phase, in this paper it is replaced by iterative conjugate−...

Received May 2009 Accepted October 2009 INTRODUCTION Learning laparoscopic skills is difficult in the current era of fast developing laparoscopic urology. There are many commercially available good-quality laparoscopy trainers, but their prohibitive costs have limited their use in developing countries. To answer this problem, we conceptualized a home-made economical digital camera coupled with ...

The Trikebot is the result of a ground-up design effort chartered to develop an effective and low-cost educational robot for secondary level education and home use. This paper describes all aspects of the Trikebot, including chassis and mechanism; control electronics; communication architecture; robot control server and student programming environment. Notable innovations include a fast-build c...

In spite of all these advantages, databases are rarely used in either case. Programs, like compilers, must run extremely fast, and slow access combined with memory overhead makes databases impractical for this particular application. Small programs like the home music catalog do not use databases because they are expensive and require additional resources. Also, the programmer must learn how to...

Closer to home, I’d like to take the opportunity to announce a new feature for Informer: an “Industry News” section. As a complement our regular coverage of IR research, we’ll be inviting representatives from start-ups and established businesses in web and enterprise search (e.g. Google, Yahoo, Autonomy, MS/Fast, Endeca and many more) to keep us up to date with all the latest product announceme...

BACKGROUND The consumption of foods, especially by children, may be determined by the types of foods that are available in the home. Because most studies use a single point of data collection to determine the types of foods in the home, which can miss the change in availability when resources are not available, the primary objective of this study was to determine the extent to which the weekly ...

BACKGROUND While previous research on fast food access and purchasing has not found evidence of an association, these studies have had methodological problems including aggregation error, lack of specificity between the exposures and outcomes, and lack of adjustment for potential confounding. In this paper we attempt to address these methodological problems using data from the Victorian Lifesty...

BACKGROUND AND PURPOSE Walking ability poststroke is commonly assessed using gait speed categories developed by Perry et al. The purpose of this study was to reexamine factors that predict home and community ambulators determined from real-world walking activity data using activity monitors. METHODS Secondary analyses of real-world walking activity from 2 stroke trials. Home (100-2499 steps/d...
