A novel tolerance feature subset selection method from incomplete data set, denoted by MaxGIIAMB, is proposed to pick out the Markov-boundary (MB), the minimal subset of features, of target variable but without making any assumption about the unknown component distribution. The classification experimental results of risk factors observed in a sample of 1841 employees of a Czech car factory demo...

Diethyl thiourea as a cause of dermatitis in a car factory. Fifteen car assembly workers became sensitized to self-skinning neoprene foam weather strips by contact with the bare forearms for the greater part of the working day. A series of patch tests showed 11 out of 11 tested to be sensitive to diethyl thiourea present in the neoprene as an accelerator. The condition cleared on modification o...

The advent of autonomous electric vehicles (AEVs) will give drivers time and space instead focusing on driving. Because this, some may want to personalize their car for work, while others customize vehicle be more suitable relaxation, which accelerate the megatrend mass individualization. However, production individualized cars faces several challenges. For example, since high-level automation ...

An auditory model based on zero-crossings with peak amplitudes (ZCPA) was used as a front-end for automatic speech recognition (ASR) with the perceptual property of adaptation as determined by psychoacoustic observations. The model performance was evaluated on the isolated digits (TIDIGITS) database using continuous density HMM recognizer in additive noise. Experimental results indicate that th...

Two groups of men of different age ranges and with the same period of lead exposure were selected for study in a recently opened car-battery factory. Two other groups of age-matched men, not exposed to heavy metals in their work, were used as controls. Morning urines were collected from control and exposed groups for determination of urinary kallikrein activity, urinary delta-amino-levulinic ac...

during centuries, humans have changed their environment into a perspective of cultural heritage using tact and wisdom. these perspectives that show the legacy of human civilization, have established a long cultural relationship via safety international pathways. hence, investing for maintenance of critical infrastructures which is the safe way, seems to be necessary. the main problem is not the...
