Frequent requests from users to search engines on the World Wide Web are to search for information about people using personal names. Current search engines only return sets of documents containing the name queried, but, as several people usually share a personal name, the resulting sets often contain documents relevant to several people. It is necessary to disambiguate people in these result s...

This paper presents a comparative study of the performance of three operating systems that run on the personal computer architecture derived from the IBM-PC. The operating systems, Windows for Workgroups (tm), Windows NT (tm), and NetBSD (a freely available UNIX (tm) variant) cover a broad range of system functionality and user requirements, from a single address space model to full protection ...

The amount of antibiotics and personal care products entering local sewage systems ultimately natural waters is increasing raising concerns about long-term human health effects. We developed an adsorptive photocatalyst, Cu0.5Mn0.5Fe2O4 nanoparticles, utilizing co-precipitation calcination with melamine, quantified its efficacy in removing paraben oxytetracycline (OTC). During melamine calcinati...

Humans often evaluate their abilities by comparing their personal performance with that of others. For this process, it is critical whether the comparison turns out in one's favor or against it. Here, we investigate how social comparisons of performance are encoded and integrated on the neural level. We collected functional magnetic resonance images while subjects answered questions in a knowle...

Broadband analog transport facilities using fiber or fiberkoax cable can play a significant role in the evolution of the network infrastructure for personal communications services (PCS’s). Low-power PCS systems require a dense grid of radio ports to provide connectivity to the telephone network. Analog transport has a number of important advantages over digital transmission facilities, includi...

Two experiments explored the effects of ingroup vs outgroup performance on the extent to which individuals value an attribute. Self-appraisals of personal standing on the attribute were examined as a potential mediator of this relationship. In both experiments, members of two groups (either experimentally created or gender groups) took a test of a bogus personality trait and received feedback a...

In the new era of wireless, mobile connectivity the possibilities of anything, anytime, anywhere access are becoming a reality. In order to deliver services and content to users in a variety of contexts, content adaptation strategies need to be developed and assessed. In this paper we present an approach to performance evaluation and capacity planning, based on a high-level system description f...

Of students who enroll in 4-year universities, 25% never finish. Precipitating causes of early departure include poor academic progress and lack of clear goals and motivation. In the present study, we investigated whether an intensive, online, written, goal-setting program for struggling students would have positive effects on academic achievement. Students (N = 85) experiencing academic diffic...

Using two email streams, we show that a personal filter trained exclusively on user feedback substantially outperforms (p ≈ 0.000) three industry-leading global spam filters not using feedback. We show that autonomous personal filters, trained on the output from a global spam filter rather than user feedback, substantially outperform (p ≈ 0.000) the global filter, if by a somewhat smaller facto...
