146. In queuing concept, the nature of the ready scenario will be studied and analysed mathematically if

(a) full details’of items in, waiting line are known

(b) arrival and ready instances are identified and could be grouped to form a ready line mannequin

(c) all variables and constants are identified and kind a linear equation

(d) the legal guidelines governing arrivals, service occasions, and the order through which the arriving models are taken into source are identified

(e) the entire above.

Ans: d

Section 3 was printed in 2008. It developed and examined a methodology for analyzing the prices and advantages of specific undergrounding proposals. The methodology has two elements: a normal weather assessment and строительство промышленных объектов a hurricane evaluation. The model used in the conventional weather evaluation includes the fundamental cost of utility capital and operations. It also contains reliability info that allows for the calculation of buyer interruption rates and interruption-related costs. The hurricane model determines infrastructure damage and related costs associated with tropical storms of hurricane strength that make landfall in Florida.

More than half of the electrocutions of electrical workers were caused by direct (from energy supply) or indirect contact with reside electrical equipment and wiring (including mild fixtures, circuit breakers, control panels, junction packing containers, and transformers) (McCann, Hunting et al. 2003, Janicak 2008). Many of these violations are associated to the use of short-term energy during building and renovation (Wheeler 2016). The Nationwide Electrical Contractors Association (NECA) has developed a consensus standard on this topic. The usual addresses how one can conduct correct planning and avoid widespread OSHA violations associated to planning, use of receptacles, and temporary lighting among different subjects (NECA 2016). For non-electrical staff, the primary trigger of electrocution was contact with overhead or underground energy traces. These deaths had been the results of failure to de-energize or protect the power strains and failure to keep up minimal clearance distances from energy lines. Lastly, another common trigger of electrocution is the improper use or care of extension cords.
