OBJECTIVE To investigate whether acute total sleep deprivation (TSD) leads to decreased cognitive control when food cues are presented during a task requiring active attention, by assessing the ability to cognitively inhibit prepotent responses. METHODS Fourteen males participated in the study on two separate occasions in a randomized, crossover within-subject design: one night of TSD versus ...

This study evaluates an approach for Land-Use Land-Cover classification (LULC) using multispectral satellite images. This proposed approach uses the Bagging Ensemble (BE) technique with Random Forest (RF) as a base classifier for improving classification performance by reducing errors and prediction variance. A pixel-based supervised classification technique with Principle Component Analysis (P...

Since the introduction of lidar technology, lidar data has been used in a wide range of applications to generate quality surface models. Accordingly, because of the importance of terrain surface models in the applications, rigorous studies have been provided to extract ground points from a mixture of ground and nonground points in a lidar point cloud. Although most filters have been shown to cl...

Errors are aversive, motivationally-salient events which prime defensive action. This is reflected in a potentiated startle reflex after the commission of an error. The current study replicates and extends previous work examining the time course of error-potentiated startle as a function of startle lag (i.e., 300 ms or 800 ms following correct and error responses). In addition, the relationship...

This paper develops and tests a model of how organizational structure influences organizational performance. Organizational structure, conceptualized as the decision-making structure among a group of individuals, is shown to affect the number of initiatives pursued by organizations, and the omission and commission errors (Type I and II errors, respectively) made by organizations. The empirical ...

OBJECTIVE To explore the possible role that functional abnormalities of the prefrontal cortex and basal ganglia play in the persistence of attention-deficit/hyperactivity disorder (ADHD) in adolescents aged 15 to 19 years. METHOD Ten male adolescents who were diagnosed with ADHD during childhood were grouped into those who continued to meet full diagnostic criteria for DSM-IV ADHD (persisters...

This paper presents a semi-automatic methodology for fire scars mapping from a long time series of remote sensing data. Approximately, a hundred MSS images from diFerent Landsat satellites were employed over an area of 32 100 km in the north-east of the Iberian Peninsula. The analysed period was from 1975 to 1993. Results are a map series of fire history and frequencies. Omission errors are 23%...

The Federal Communications Commission (FCC) mandate for locating the position of wireless 911 callers is fueling research in the area of mobile-positioning technologies. Overlapping multipath propagation is one of the main sources of mobile-positioning errors, especially in fast channel fading situations. In this paper we develop a technique for detecting and providing an estimate of the number...

The Health Quality & Safety Commission works with clinicians and health service providers to improve the quality and safety of health and disability services. One of the Commission’s priorities is for district health boards (DHBs) to implement paper or electronic medicine reconciliation in all hospitals by January 2012.1 To date, 17 DHBs have implemented medicine reconciliation based on the saf...
