Rapid and reliable test of SOCs necessitates upfront consideration of the test power issues. Special attention should be paid to scanbased cores as the test power problem is more severe due to excessive switching activity stemming from scan chain transitions during shift operations. We propose a scan chain modification methodology that transforms the stimuli to be inserted to the scan chain thr...

states at circuit nodes may erroneously change. Further, BIST schemes with random test patterns may need an excessive amount of energy because of longer test length. Abstract I n a scan-based system with a large number of flip-flops, a major component of power is consumed during scanshift and clocking operation in test mode. In this paper, a novel scan-path architecture called double-tree scan ...

Background. To determine whether transabdominal screening can be used to screen women with short cervix on transvaginal scan. Methods. The study was done between 18 and 20 weeks of gestation. Transabdominal scan was done and cervical length was measured. Transvaginal scan was also done and cervical length was measured. An attempt was made to find out whether transabdominal scan be used to predi...

Neurology 2012;78:688–689 The Food and Drug Administration (FDA) recently approved [I]ioflupane ([I]-fluoropropyl CIT), a dopamine transporter (DAT) radioligand, for SPECT to “assist in the evaluation of adult patients with suspected parkinsonian syndromes (PS).”1 This permits physicians to prescribe [I]ioflupane SPECT scans as part of clinical practice. Advertisements encourage clinicians to o...

| This paper presents an algorithm framework for the scan-chain optimization problem in multiple-scan design methodology. It also presents algorithms we propose based on the framework; these are the rst algorithms ever proposed for multiplescan designing. Experiments using actual design data show that, for ten scan-paths, our algorithms achieved a 90% reduction in scan-test time at the expense ...

Four patients with sonographic suggestion of hepatic hemangioma are studied with Tc99m-labeled RBC scan. The scan findings are compaired with other imaging modalities. Lesions as small as 36 mm could be detected by this method. Tc99m labeled RBC scan is a valuable tool to differentiate hepatic hemangioma from other space occupying lesion of the liver.

This paper presents a new generalisation of simultaneous localisation and mapping (SLAM). SLAM implementations based on extended Kalman filter (EKF) data fusion have traditionally relied on simple geometric models for defining landmarks. This limits EKF-SLAM to environments suited to such models and tends to discard much potentially useful data. The approach presented in this paper is a marriag...
