IT infrastruktūras modernizācija mazā uzņēmumā
2018
Kvalifikācijas darba mērķis ir pilnveidot un modernizēt jau esošu informācijas tehnoloģijas infrastruktūru, kas ietver aparatūru, programmatūru, tīkla resursus un pakalpojumus, lai nodrošinātu pilnvērtīgu uzņēmuma IT vides darbību un pārvaldību. Darba teorētiskajā daļā veikta esošā uzņēmuma datortīkla izpētē, lai izprastu esošās problēmas un spētu definēt piemērotākus risinājumus darba plānošanas gaitā. Rezultātā ir veikta daļēja infrastruktūras iekārtu nomaiņa un konfigurēšana, kā arī ieviesta jauna lietojumprogrammatūra un servisi uzņēmuma darbības procesu modernizācijai.
A scalable multiagent system architecture for interactive applications
2013
Interactive applications like crowd simulations need to properly render the virtual world while simulating the interaction of thousands of agents at the same time. The computational workload generated by these two tasks highly increases with the number of the simulated agents, requiring a scalable design of the multiagent system. In this paper, we present, in an unified manner, a distributed multiagent system architecture that can manage large crowds of autonomous agents at interactive rates while rendering multiple views of the virtual world being simulated. This architecture consists of a distributed multiagent system and a complementary distributed visualization subsystem. We also presen…
A distributed visualization system for crowd simulations1
2011
The visualization system of large-scale crowd simulations should scale up with both the number of visuals views of the virtual world and the number of agents displayed in each visual. Otherwise, we could have large scale crowd simulations where only a small percentage of the population is displayed. Several approaches have been proposed in order to efficiently render crowds of animated characters. However, these approaches either render crowds animated with simple behaviors or they can only support a few hundreds of user-driven entities. In this paper, we propose a distributed visualization system for large crowds of autonomous agents that allows the visualization of crowds animated with co…
Positive L1 observer design for positive Switched systems
2014
Published version of an article in the journal: Circuits, Systems, and Signal Processing. Also available from the publisher at: http://dx.doi.org/10.1007/s00034-013-9737-6 This paper investigates the problem of L1 observer design for positive switched systems. Firstly, a new kind of positive L1 observer is proposed for positive switched linear delay-free systems with observable and unobservable subsystems. Based on the average dwell time approach, a sufficient condition is proposed to ensure the existence of the positive L1 observer. Under the condition obtained, the estimated error converges to zero exponentially, and the L1 -gain from the disturbance input to the estimated error is less t…

Investigating Long-Range Dependence in E-Commerce Web Traffic
2016
This paper addresses the problem of investigating long-range dependence (LRD) and self-similarity in Web traffic. Popular techniques for estimating the intensity of LRD via the Hurst parameter are presented. Using a set of traces of a popular e-commerce site, the presence and the nature of LRD in Web traffic is examined. Our results confirm the self-similar nature of traffic at a Web server input, however the resulting estimates of the Hurst parameter vary depending on the trace and the technique used.
Latency-Oblivious Distributed Task Scheduling for Mobile Edge Computing
2018
Mobile Edge Computing (MEC) is emerging as one of the effective platforms for offloading the resource- and latency-constrained computational services of modern mobile applications. For latency- and resource-constrained mobile devices, the important issues include: 1) minimize end-to-end service latency; 2) minimize service completion time; 3) high quality-of-service (QoS) requirement to offload the complex computational services. To address the above issues, a latencyoblivious distributed task scheduling scheme is designed in this work to maximize the QoS performance and goodput for the MEC services. Unlike most of the existing works, we consider the latency-oblivious property of different …
EPR DOSIMETRY IN A MIXED NEUTRON AND GAMMA RADIATION FIELD
2004
Suitability of Electron Paramagnetic Resonance (EPR) spectroscopy for criticality dosimetry was evaluated for tooth enamel, mannose and alanine pellets during the 'international intercomparison of criticality dosimetry techniques' at the SILENE reactor held in Valduc in June 2002, France. These three materials were irradiated in neutron and gamma-ray fields of various relative intensities and spectral distributions in order to evaluate their neutron sensitivity. The neutron response was found to be around 10% for tooth enamel, 45% for mannose and between 40 and 90% for alanine pellets according their type. According to the IAEA recommendations on the early estimate of criticality accident a…

It is arranged participating teacher survey regarding usability of applied environment and made conclusions about appropriateness of developed approach.
WebService standartu pielietojums sistēmu integrācijā
2015
Daudziem uzņēmumiem šobrīd ir izveidotas lielas sistēmas, kurās tie vairs nevēlas ieviest lielas izmaiņas un sistēmu integrācijas ar citām sistēmām. Tādēļ tiek meklētas citas iespējas, kā paplašināt funkcionalitāti, lai būtu iespējams klientiem piedāvāt pakalpojumus, piemēram, iegūt datus dažādos griezumos no dažādām sistēmām. Darba mērķis: izpētīt lietotņu serverus un to izstrādes vides, lai programmatūras izstrādātājam būtu iespējams izvēlēties atbilstošu lietotņu serveri un izstrādes vidi saskaņā ar konkrētām prasībām. Maģistra darbā tiek apkopota informācija par esošiem lietotņu serveriem, kādi šobrīd ir pieejami lietotājiem. Darba autors savā darbā ir parādījis, kā izveidot jaunu sistē…
