frequency distribution

Voorbeeldzinnen

1. Distribution in time and place of loud, low and mid frequency impulsive sounds
2. Transmission and distribution system operators should be required to deliver a high level of service to final customers in terms of the frequency and duration of interruptions.
3. The geographical distribution of the sampling points and the sampling frequency must ensure that the results of the analysis are as representative as possible for the area considered.
4. Proportion of days and their distribution within a calendar year over areas of a determined surface, as well as their spatial distribution, in which anthropogenic sound sources exceed levels that are likely to entail significant impact on marine animals measured as Sound Exposure Level (in dB re 1μPa2.s) or as peak sound pressure level (in dB re 1μPapeak) at one metre, measured over the frequency band 10 Hz to 10 kHz (11.1.1)
5. establish a sampling programme of bivalve molluscs in the production area which is based on the examination of established data, and with a number of samples, a geographical distribution of the sampling points and a sampling frequency which must ensure that the results of the analysis are as representative as possible for the area considered.
6. The Commission's market investigation confirmed that the proposal leads to numerous horizontal and vertical overlaps in the fields of power generation (see Section A), power transmission and distribution (B), rail transport technology (C), frequency inverters (D), metallurgical and electrical plant building (E), low-voltage switchgear (F), building technology (G), infrastructure and ropeways (H) and other IT services (I).
7. Brake system as specified in clause 4.2.4.3 Derailment detection as specified in clause 4.2.3.4.11 Fire detection as specified in clause 4.2.7.2.3 Failure of the driver vigilance device as specified in clause 4.2.7.8 Control-command and signalling subsystem information as specified in clause 4.2.7.9 This monitoring of the functions and equipment shall be continuous, or at a frequency to ensure reliable detection of failure. For Class 1 trains the system shall also be linked to the on-board diagnosis data recorder to allow traceability. For all classes of trains the recording related requirements for control-command and signalling subsystem as described in the Control-Command and Signalling TSI 2006 are mandatory. Indication to the driver shall be made of such detection, and shall require reaction by the driver. Appropriate automatic braking shall be required where a functional failure occurs on the driver vigilance device or on the control-command and signalling subsystem onboard the trains. 4.2.7.11. Particular specification for tunnels 4.2.7.11.1. Passenger and train crew areas equipped with air conditioning The train crew shall be able to minimise the distribution and inhalation of fumes in the event of a fire. For this purpose it shall be possible to switch off or close all means of external ventilation and switch off air conditioning. It is permissible to trigger these actions by remote control per train, or at the level of a single vehicle. 4.2.7.11.2. Public address system Requirements for communication systems are specified in clause 4.2.5.1.
