the submodules with the property of the title ( a submodule $n$ of an $r$-module $m$ is called strongly dense in $m$, denoted by $nleq_{sd}m$, if for any index set $i$, $prod _{i}nleq_{d}prod _{i}m$) are introduced and fully investigated. it is shown that for each submodule $n$ of $m$ there exists the smallest subset $d'subseteq m$ such that $n+d'$ is a strongly dense submodule of $m$...
Collaborative software tools allow people to share documents and knowledge via Internet, in a simple, economic and efficient way. Unfortunately collaborative software often relies heavily on visual features and dynamic technologies with user interfaces that are difficult to use via screen reader, or are sometimes even inaccessible for the blind. In this paper we illustrate and discuss results o...
Radio frequency identification (RFID) is a new generation of automatic identification systems, based on wireless communication technology. In these systems all the tags using one communication channel to communicate with the reader. When two or more tags transmit their data to the reader simultaneously, their transmitted signals will collide. Resolving this collision has a direct impact on the ...
OBJECTIVE To investigate the significance of intra-appendiceal air at CT for the evaluation of appendicitis. MATERIALS AND METHODS We retrospectively analyzed 458 patients (216 men, 242 women; age range, 18-91 years) who underwent CT for suspected appendicitis. Two independent readers reviewed the CT. Prevalence, amount, and appearance of intra-appendiceal air were assessed and compared betwe...
The wide adoption of Radio Frequency Identification (RFID) for applications requiring a large number of tags and readers makes critical the reader-to-reader collision problem. Various anticollision protocols have been proposed, but the majority require considerable additional resources and costs. Distributed Color System (DCS) is a state-of-the-art protocol based on time division, without notew...
