The bee colony optimization metaheuristic (BCO) is proposed in the paper. BCO represents new capable to solve difficult combinatorial problems. artificial behaves partially alike, and differently from colonies nature. In addition proposing as a metaheuristic, we also describe paper two algorithms that call system (BS) fuzzy (FBS). case of FBS agents (artificial bees) use approximate reasoning rules logic their communication acting. this way, deterministic problems, well problems...
A multifrequency campaign on the BL Lac object PG 1553+113 was organized by Whole Earth Blazar Telescope (WEBT) in 2013 April-August, involving 19 optical, two near-IR, and three radio telescopes. The aim to study source behaviour at low energies during around high-energy observations Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) telescopes April-July. We also analyse UV X-ray data acquired Swift XMM-Newton satellites same period. WEBT satellite allow us detail synchrotron emission...
ABSTRACT Among active galactic nuclei, blazars show extreme variability properties. We here investigate the case of BL Lac object S4 0954+65 with data acquired in 2019–2020 by Transiting Exoplanet Survey Satellite (TESS) and Whole Earth Blazar Telescope (WEBT) Collaboration. The 2-min cadence optical light curves provided TESS during three observing sectors nearly 1 month each allow us to study fast great detail. identify several characteristic short-term time-scales, ranging from a few...
In this paper a brief review of new technology forecasting methods is given. We described the main influences and decision factors adoption telecommunications services/technologies. The Bass model in order to forecast applied. demonstrate procedure diffusion parameters estimation case HDTV service.
Design and development of systems for delivering real-time information to people with disabilities elderly persons need be based on defined user requirements. For this purpose, the requirements have been in paper according everyday needs who use traffic networks move closed spaces. The logical presentation functionality informing system operation its subsystems includes all (data) important designing a delivery system. presents conceptual architecture services related environment Internet...
Wavelength converters placement (WCP) in all-optical WDM networks belongs to the class of hard combinatorial optimization problems. So far, this problem has been solved by various heur ...
Globalization and technological advances have made significant changes in city development. To integrate all dimensions of the smart city, communication networks are essential. Smart infrastructure integrates transport, electricity, water distribution, sensing systems, information technologies with networks. make optimal use data available from a range sensors cities need reliable This paper gives an overview optical for application systems infrastructures that should handle capacity applications.
One of the basic questions in field microeconomics is how to make decisions about allocation limited resources for technological improvement. The aim this study exactly propose a model that will help firms making kind decisions. puts employees’ stress level central place. There was hypothesis introduced based on analyses correlation with particular parameters business, recommendations improvements can be reached.As data collection tool, two questionnaires were used. First questionnaire...
Abstract The increasing demands for higher spectrum efficiency have made elastic optical networks (EON) to be an interesting area the research community. possibility that some network parameters are changed according different types of services allows paths can established using just enough as needed. Since individual separated by guard bands, a large part available is wasted. efficient utilization capacity among operators' major concerns and therefore, traffic engineering techniques provide...
The entire society, and particularly the transportation companies, has an interest to improve traffic safety. Besides more than 3000 lost lives on roads every day, there are significant financial consequences of road accidents (RTAs). purpose this article is design efficient model for providing information about driver propensity RTAs based assessing their personality traits. This achieved by creating a fuzzy inference system (FIS) where inputs scores from implemented psychological...
This paper aims to study the lightpaths provisioning problem in optical WDM networks with scarce available wavelengths under static (off-line) traffic demands such that network operator's (NO's) revenue is maximized.To achieve this goal, a NO has be addressed issue how solve call admission control jointly routing and wavelength assignment (RWA) efficient manner.The improved bee colony optimization (BCOi) metaheuristic applied considered maximization (Max-Rev) problem.We evaluated...
This paper proposes a modification of traffic forecast model generated by residential and small business (SOHO, Small Office Home Office) users. The includes forecasted values different relevant factors competition on broadband market. It allows forecasting the number users for various technologies interaction impact long-standing as well new technology entrant All necessary parameters are evaluated Serbian long-term results given. analyses evaluations performed important inputs transport...
This paper is dealing with functional organization of a call center based on human operator work. Due to significant fluctuations user demands during the day and from day, determination required number agents appears as actual giving opportunities for efficient management. The purpose this develop mathematical model optimal resource allocation in order provide satisfactory quality service at all times, without having more than necessary. objective find best staffing levels or schedule that...
In this paper, we consider diffusion process of new services in the residential market. We described main influences and decision factors telecommunication adoption. order to forecast adoption service, theory is applied. Building upon Bass model, proposed an innovative approach, which encompasses a model for market potential estimation. Based on such analyses, performed Internet Protocol Television (IPTV) demand Serbian until end year 2012. Such are not only important providers...
The well-known routing approaches, such as fixed routing, fixed-alternate and adaptive are the basic strategies that widely used for resolving problem in optical WDM networks. It is shown best network performances could be achieved by applying dynamic or algorithms. In this paper, an implementation of a algorithm wavelength routed networks (WRON) based on multi-criteria optimization technique examined. aim to find set dominant paths among all possible between two nodes network. For purpose,...
