This paper discusses the viability of a BIST implementation for the sinusoidal histogram technique classically used for ADC testing. An original approach based on (i) approximations to estimate the ADC parameters, (ii) decomposition of the global test in a code-after-code test procedure and (iii) piece-wise approximation to compute the ideal histogram is developed. These three features allow a ...

Education significantly impacts cognitive performance of older adults even in the absence of dementia. Some cognitive tests seem less vulnerable to the influence of education and thus may be more suitable for cognitive assessment of older adults with heterogeneous backgrounds. The objective of this study was to investigate which tests in a cognitive battery were less influenced by educational l...

UNLABELLED Every traumatic experience triggers the cognitive functions. Among the people who have experienced a trauma, the cognitive functions are diminished and these people are exposed to the negative effects of it. People with the diminished cognitive functions are especially sensitive to the PTSD occurrence. AIM The aim of this study was to evaluate selected cognitive functions with the ...

OBJECTIVE Assessment of fall risk of elderly people is a critical issue. Dual-task (DT) ability is a criterion for risk assessment. We developed new concept software based on Microsoft (Redmond, WA) Kinect™ for assessing DT ability. The software is named "Dual-Task Tai Chi" (DTTC) and includes Tai Chi and number place (Sudoku) components. The purpose of this study is to validate the DTTC test f...

We present a methodology for designing better learning environments. In Phase 1, 6th-grade students’ (n = 223) prior knowledge was assessed using a difficulty factors assessment (DFA). The assessment revealed that scaffolds designed to elicit contextual, conceptual, or procedural knowledge each improved students’ ability to add and subtract fractions. Analyses of errors and strategies along wit...

This paper describes an objective speech quality assessment method developed for the Hungarian NMT450 mobile telephone system. The method is based on a psychoacoustic front end followed by a cognitive modeling component. Special problems of the NMT system, such as hand-overs, the effects of automatic gain control (AGC) and intrusion of signaling noise are addressed in the cognitive module. Corr...

In this study we explored the use of Brain Computer Interface (BCI) and Eye-Tracking (ET) technology both as augmentative and alternative communication (AAC) tool and to assess cognitive deficits. Specifically, we focused on the possible development of a neuropsychological battery for cognitive assessment based on the integration of BCI and ET tools. To preliminary test this approach we assesse...

The Swedish driving test (SDT) was compared to theoretical concepts found in research literature (CRLs) with respect to the rated importance of the CRLs for the overall assessment of risk awareness and the five specific assessment areas used in the SDT. 116 traffic inspectors responded to questionnaires. Results show that visual search was the CRL given the highest rating, and that the assessme...
