This is the beginning of a series discussing methodological approaches used in the social sciences. This article outlines the general problems and difficulties associated with a common method of statistical inference in psychology (my background) and other social science fields: null hypothesis significance testing (hereafter NHST). This introduction can serve as a starting point for researcher...

This month we demonstrate multiple contrast adjustment using the False Detection Rate method (FDR). The GNU S language, "R" is used to implement this procedure. R is a statistical programming environment that is a clone of the S and S-Plus language developed at Lucent Technologies. In the following document we illustrate the use of a GNU Web interface to the R engine on the "rss" server, http:/...

A radio transceiver normally provides received signal strength (RSS) quantized with 1 dB or higher step size. Currently, we know of no application which has demonstrated a need for sub-dB RSS estimates. In this paper, we demonstrate the need for, and benefits of, greater resolution in RSS for breathing rate monitoring and gesture recognition. Measuring RSS requires orders of magnitude less band...

Neuroplasticity underlies the brain's ability to alter perception and behavior through training, practice, or simply exposure to sensory stimulation. Improvement of tactile discrimination has been repeatedly demonstrated after repetitive sensory stimulation (rSS) of the fingers; however, it remains unknown if such protocols also affect hand dexterity or pain thresholds. We therefore stimulated ...

Real-time user localization in indoor environments is an important issue in ambient assisted living (AAL). In this context, localization based on received signal strength (RSS) has received considerable interest in the recent literature, due to its low cost and energy consumption and to its availability on all wireless communication hardware. On the other hand, the RSS-based localization is cha...

This paper extends earlier work by the authors in identifying guiding rules for natural language (NL) requirements specifications (RSs) by analysing a few sets of requirements documents from different domains. It presents guiding rules that help reduce ambiguities and imprecision in NL RSs. It validates these rules by applying them to sentences in several industrial strength NL RSs.

Mature squamates possess hypertrophied regions of the distal urinary ducts, the renal sexual segment (RSS). The RSS is believed to provide seminal fluid that mixes with sperm and is released into the female cloaca during coitus. This study is the first to describe ultrastructure of the RSS in a lizard collected throughout the active season. The species examined, Scincella laterale, represents t...

1. INTRODUCTION There has been an explosion in the amount of available news and current event information on the Internet. 24-hours news outlets and independent bloggers alike flood the wires with a constant stream of data. Though an increasing number of people rely on the Internet as their primary source of news and current events, it is becoming increasingly difficult for users to find what t...

In RSS aggregator, the important issue is how to make the feeds information more manageable for RSS subscriber. In this paper, we propose a suffix tree based RSS feeds document clustering in Chinese RSS aggregator. We construct a suffix tree with meaningful Chinese words, and choose the phrases with high score given by a formula as document features. We cluster document using group-average algo...

In this paper, different representations of WiFi access point signal information are tested on a hierarchical indoors localization system to identify the one that yields the least amount of localization error. Four representations were considered: Received Signal Strength (RSS) in dBm, RSS in mW , Visibility and both RSS in dBm and Visibility. The localization system was tested in two different...
