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...
-Radio frequency identification (RFID) is an automatic identification system working through radio frequency (RF). Tag collision occurs while two or more than two tags deliver their unique identification (UID) to the reader. Since collision, which would significantly affect the efficacy of RFID, has been one of the major study issues for RFID technology, we have developed a solution, bit compet...
PURPOSE To compare cardiac-triggered dual-echo spin-echo and magnetization transfer-prepared gradient-echo (MT-GE) MR imaging in the detection of multiple sclerosis (MS) lesions in the spinal cord. METHODS The cervical spinal cord in 20 patients with MS and in nine healthy volunteers was examined with spin-echo and MT-GE MR imaging. Sagittal images were scored for number of lesions, certainty...
Despite considerable media attention, portable electronic readers (e-readers) have not yet had a significant consumer impact. They offer several features unavailable in print media, such as easily accessible content and potential for interactive capacity similar to what can be found on the Internet. Flawed design and high cost, however, may inhibit wide end-user adoption. Using a mix of scholar...
