Play media Enciphering and deciphering using an Enigma machine A German Enigma operator would be given a plaintext message to encrypt. For each letter typed in, a lamp indicated a different letter according to a pseudo-random substitution, based upon the wiring of the machine.
With the current surge in national economy the industrial traffic has increased many folds in terms of quantity of load and traffic volume.
This results in early deterioration of the roads. Also the serviceability reduces hampering the industry's supply of raw material and transport of finished goods.
An efficient road transportation system is of vitally important for smooth operations of industrial units. Construction of new roads needs an enormous investment. However, once constructed the road network system requires huge resources to maintain serviceability and to ensure safe passage at an appropriate speed and with low VOC Vehicle Operating Cost.
Road maintenance is therefore an essential function and should be carried out on a timely basis. The cost of providing and maintaining the roads for the industrial areas at an acceptable serviceability level is quite high.
It is therefore essential for a transportation engineer to attempt establishing an acceptable pavement condition level from economic, safety and environmental point of view.
In today's economic environment of constrained budgets, as the existing road infrastructure has aged, a more systematic approach towards determining maintenance and rehabilitation needs is necessary. The efficient pavement management system shall provide objective information and useful analysis to ensure consistent and cost effective decisions related to preservation of existing industrial road network in healthy condition.

PhD Dissertation, University of Leeds. Guidelines on Calibration and Adaptation. A wireless local area network LAN is a network that connects computer systems and devices within the same geographical area but without the use of wire.
Fragmentation threshold is one of the parameters used in a wireless local area network which specifies the values to decide if the Media Access Control MAC Service Data Unit MSDU received from the higher layer network needs fragmentation before transmission.
The number of fragments to be transmitted is calculated based on the size of the MSDU and the fragmentation threshold. Based on the graphical results obtained, it can be said that fragmentation increases the size of queue and the number of data dropped in a transmission, and also the smaller the fragmentation, the more increase in the retransmission attempts.

The mechanical subsystem consists of a keyboard; a set of rotating disks called rotors arranged adjacently along a spindle; one of various stepping components to turn at least one rotor with each key press, and a series of lamps, one for each letter.
