A series of three field experiments were conducted to evaluate the level of autonomous mobility for the Army’s Experimental Unmanned ground Vehicle (XUV), during which an assessment of operator mental workload was performed. Workload data collection methods employed were the “NASA Task Load Index”, the “Overall Workload” scale, and experimenter observation during partially autonomous operations...

This study investigates the effects of thinking aloud on cognitive effort in translation as a function source-text difficulty level. It does so by considering time task, duration different phases (i.e., orientation, draft, revision), processing source and target texts, quality. Twenty participants took part an English–Chinese experiment, which comprised two matched sessions – translating while ...

A preliminary set of analyses are presented, where workload was examined in 32 adults infected with the human immunodeficiency virus (HIV). Like current COVID-19 pandemic (caused by SARS-CoV-2 virus), HIV can produce a wide variety symptoms, including various levels cognitive dysfunction. In fact, recent meta-analysis estimates that 39 million globally HIV, 42.6% exhibit some form HIV-associate...

Criminal investigative work entails a diverse array of tasks and responsibilities, ranging from interviewing suspects victims to managing the paperwork necessary follow-ups for each case. The present study sought evaluate workload impacts police investigators in metropolitan agency. NASA-Task Load Index (NASA-TLX), well-established human factor measure workload, was administered on 759 as quant...

Navy Ships A is a Republic of Indonesia Ship type LPD (Landing Platform Dock) which has the main task and additional duties as Naval Hospital Auxiliary Ship. In their daily life, carries out maritime security operations to maintain sovereignty Indonesia, well carry humanitarian social activities. This makes workload personnel in high category. And it causes decrease productivity morale will res...

The purpose of this research was to compare vigilance performance over time for visual, auditory, and vibrotactile tasks, while simultaneously recording oxygenation in the frontal lobe to assess physiological resource utilization. Subjective workload was assessed in each condition using the NASA Task Load Index (NASA-TLX). The data indicate a significant effect of time-on-task in all experiment...

The operation of the electricity sector has resulted in more sophisticated equipment and requires more attention from operators. This results in increased cognitive load and environments more conducive to error, which can cause failures that result in significant economic losses, physical damage, or threats to human life. This research aims to evaluate the workload of the operators in two Elect...

Abstract OBJECTIVE To describe the feasibility and technique for performing laparoscopic ultrasound (LUS) of liver in dogs. ANIMALS 12 client-owned dogs presenting elective surgery from January 1, 2022, to October 31, 2022. METHODS Laparoscopic exploration LUS were performed all Dogs positioned reverse Trendelenburg laterally rotated facilitate access lobes. Time perform LUS, ability visualize ...
