Translation of "dégradation admissible des performances " (French → English) :

allowable performance degradation

Definition: Considerable cultural variations occur in the presentation of this disorder, and two main types occur, with substantial overlap. In one type, the main feature is a complaint of increased fatigue after mental effort, often associated with some decrease in occupational performance or coping efficiency in daily tasks. The mental fatiguability is typically described as an unpleasant intrusion of distracting associations or recollections, difficulty in concentrating, and generally inefficient thinking. In the other type, the emphasis is on feelings of bodily or physical weakness and exhaustion after only minimal effort, accompanie ...[+++]d by a feeling of muscular aches and pains and inability to relax. In both types a variety of other unpleasant physical feelings is common, such as dizziness, tension headaches, and feelings of general instability. Worry about decreasing mental and bodily well-being, irritability, anhedonia, and varying minor degrees of both depression and anxiety are all common. Sleep is often disturbed in its initial and middle phases but hypersomnia may also be prominent. | Fatigue syndrome

The difficulties for infrastructure projects in gaining access to long-term private finance or public funding should not lead to a deterioration in performance on the part of transport, telecommunication and energy systems nor the slowing down of broadband penetration.

‘bin-specific coefficient of performance’ (COPbin(Tj)) or ‘bin-specific primary energy ratio’ (PERbin(Tj)) means the coefficient of performance of the heat pump space heater or heat pump combination heater using electricity, or primary energy ratio of the heat pump space heater or heat pump combination heater using fuel specific for every bin in a season, derived from the part load for heating, declared capacity for heating and declared coefficient of performance for specified bins and calculated for other bins by interpolation or extrapolation, corrected where necessary by the degradation ...[+++] coefficient.

a description of operation in degraded mode (when equipment or functions described in this TSI suffer safety failures) as far as can reasonably predicted, together with the related acceptable limits and operating conditions of the unit that could be experienced.

A study examining the effects of alcohol in an unpredictable traffic situation, which required subjects to brake suddenly and then make an evasive manoeuvre, showed clear evidence of the degrading effects of alcohol upon driving performance in emerging situations at BACs below 50.
