Abstract The telecommunication and radioelectronic systems with redundancy are widely used in different branches of human activity. To provide the necessary reliability level equipment, operation system is utilized. That contains intended use, maintenance, repair, technical condition monitoring, others. damages, faults failures usually observed during lifecycle systems. They can lead to deterio...

the aim of this research is to prioritize the key factors for implementation of idea virtual bank (ivb) in telecommunication industry. the current applied and descriptive research was conducted based on a survey. the population of this research consisted of all users of ivb and idea submitters to suggestion system of telecommunication industry in province of razavi-khorasan that 70 of them were...

We consider a multi-layer network design model arising from a real-life telecommunication application where traffic routing decisions imply the installation of expensive nodal equipment. Customer requests come in the form of bandwidth reservations for a given origin destination pair. Bandwidth demands are expressed as a multiple of nominal granularities. Each request must be single-path routed....

Steady growth in the telecommunication industry providing data, voice and video is very likely to continue in the foreseeable future. This growth is supported by expansion into the new markets, especially in Asia, accelerated widespread of wireless and broadband technology, and strong demand for more efficient, power saving solutions. As the result of the growth, the telecommunication infrastru...

Digital equipment such as computers, telecommunication systems and instruments use microprocessors that operate at high frequencies allowing them to carry out millions or even billions of operations per second. A disturbance in the electrical supply lasting just a few milliseconds can affect thousands or millions of basic operations. The result may be malfunctioning and loss of data with danger...

BACKGROUND Medical education in pathology and histology in low-resource countries face many obstacles because of equipment cost and telecommunication deficiencies. Digital Pathology may provide solutions. We report student experience to virtual slides on a local network and a remote image server. METHODS Using an iPad tablet device, fifty 3rd and 4th year medical students viewed digital patho...

Mobile data traffic has been growing at an increasing rate with the popularity of smartphones, tablets, and other wireless devices. To reduce the load on the network, mobile network operators deploy femtocells to increase their coverage and performance and to eliminate wireless notspots. Femtocells are low-cost devices that connect a new femtocell network architecture to the core telecommunicat...

The paper deals with a multi-layer network design problem for a high-speed telecommunication network based on Synchronous Digital Hierarchy (SDH) and Wavelength Division Multiplex (WDM) technology. The network has to carry a certain set of demands with the objective of minimizing the investment in the equipment. The different layers are the fiber-layer, 2,5Gbit/s-, 10Gbit/sand WDM-systems. Seve...

Telecommunication and broadcasting systems using radio-relay/base stations on board the high altitude platforms are expected to create the largest business market among its possible applications. Telecommunications Advanced Organization (TAO) and Communications Research Laboratory (CRL) is conducting R&D on the telecom and broadcasting system to demonstrate its feasibility. Prototype onboard eq...
