The massive and automated access to Web resources through robots has made it essential for Web service providers to make some conclusion about whether the "user" is a human or a robot. A Human Interaction Proof (HIP) like Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) offers a way to make such a distinction. CAPTCHA is a reverse Turing test used by Web serv...

we compare two approaches for a markovian model in flexible manufacturing systems (fmss) using monte carlo simulation. the model which is a development of fazlollahtabar and saidi-mehrabad (2013), considers two features of automated flexible manufacturing systems equipped with automated guided vehicle (agv) namely, the reliability of machines and the reliability of agvs in a multiple agv jobsho...

Publication bias in animal research, its extent, its predictors, and its potential countermeasures are increasingly discussed. Recent reports and conferences highlight the potential strengths of animal study registries (ASRs) in this regard. Others have warned that prospective registration of animal studies could diminish creativity, add administrative burdens, and complicate intellectual prope...

This paper constitutes a study of several classical and original methods for a speaker adaptation of the acoustic hidden Markov models of an automatic speech recognition system (ASRS). Most of today’s real applications require that the speaker adaptation process continuously improves the performance of the underlying ASRS, as more utterances are pronounced by a new speaker. The first part of th...

objective(s): gallium‐68 (ga‐68) is an ideal research and hospital‐based pet radioisotope. currently, the main form of ga‐68 radiopharmaceutical that is being synthesised in‐house is ga‐68 conjugated with dota based derivatives. the development of automated synthesis systems has increased the reliability, reproducibility and safety of radiopharmaceutical productions. here we report on our three...

This study analyses the concept of cost functions for semi-automated Straddle Carrier (SC), Rubber Tyred Gantry (RTG) and automated Rail Mounted Gantry (RMG) container yard operating cranes. It develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

BACKGROUND/AIMS Attention-deficit/hyperactivity disorder (ADHD) is often overlooked in adults; moreover, the problem seems to be even more critical in women. In the present, observational screening study, a clinical, particularly adult outpatient population was examined regarding frequency and severity of a likely ADHD, whereby sex differences were of particular interest. METHODS 224 particip...

The World Health Organization adult ADHD self-report scale (ASRS): a short screening scale for use in the general population. Q Do the long and short forms of the attention deficit/hyperactivity disorder (ADHD) self-report scale effectively diagnose ADHD in adults? METHODS Design: Prospective diagnostic cohort study. Patients: 154 people aged 18–44 years who participated in the US National Como...

and MS Thesis defense Date: 13th April 2009 Automatic Speech Recognition systems (ASRs) recognize word sequences by employing algorithms such as Hidden Markov Models. Given the same speech to recognize, the different ASRs may output very similar results but with errors such as insertion, substitution or deletion of incorrect words. Since different ASRs may be based on different algorithms, it i...
