Optical fiber sensors are now practically deployed in special disciplines such as structural health monitoring, distributed vibrations sensing, surveillance and even at other fields. Thought interesting technology, there are still many persistent barriers for its massive wide scale utilization. Should optical fiber sensing system play more dominant role in the future as compared to more traditional...
This paper tackles migration of virtual machines, and the migration reliability. The migration is seen as a reliable operation, but this assumption is not true and almost no work on this topic has been published. In order to quantify the migration successful rate, we designed and implemented framework for autonomous migration evaluation, network availability testing, and reporting. This framework...
The methodology specifies a procedure for measuring of data transmission speed for the assessment of compliance with the conditions proscribed for holders of licenses for usage frequencies in the 800, 1800 and 2600 MHz bands, for the operation of mobile systems according to the LTE standard. The achievement of specified data transmission speed is a key parameter for evaluating the coverage of the...
Optical burst switching suffers from burst contention, which can occur even under low load. This issue was investigated by Coutelen et al., 2009 and led to the CAROBS framework. Therein, the authors considered burst concatenation, and with the recourse to wavelength conversion throughout signal regeneration, can resolve all burst contentions, offering then a loss-free OBS framework. However, CAROBS...
A Michelson-type visible spatial interferometric method is used to measure very high speed vibrations of a bassreflex loudspeaker, and further its resonant frequency. The goal of investigation is to create the model for measurement of nonelectric, low-amplitude, high-speed alternating physical quantities. The contribution of this paper is this new application area.
