The distributed Slow Control System of the XENON100 experiment
2012
The XENON100 experiment, in operation at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, was designed to search for evidence of dark matter interactions inside a volume of liquid xenon using a dual-phase time projection chamber. This paper describes the Slow Control System (SCS) of the experiment with emphasis on the distributed architecture as well as on its modular and expandable nature. The system software was designed according to the rules of Object-Oriented Programming and coded in Java, thus promoting code reusability and maximum flexibility during commissioning of the experiment. The SCS has been continuously monitoring the XENON100 detector since mid 2008, remotely recordi…
Uz lietotāja modeli balstīta personalizēta adaptīva e-studiju sistēma
2017
Promocijas darbs ir veltīts uz lietotāja modeli balstītas personalizētas adaptīvas e-studiju sistēmas izveides metožu izstrādei, lai veicinātu un uzlabotu e-studiju izmantošanu apmācības procesā. Darbā apskatīti adaptīvajās sistēmās iekļaujamie pamatmodeļi, īpašu uzmanību veltot lietotāja modelim un eksistējošajām adaptācijas metodēm. Balstoties uz esošo risinājumu analīzi, ir izstrādāts uz datu dzīves ilgumu bāzēts lietotāja modelis un piedāvātas trīs jaunas adaptācijā izmantojamās metodes: apmācāmo grupu veidošanas metode, kursa optimālās tēmu secības izveides metode un tēmu secības organizēšanas metode. Izstrādātais lietotāja modelis un adaptācijas metodes nodrošina iespēju katram sistēm…
International activities of knowledge-intensive small- and medium-sized enterprises: The example of an open source software firm
2009
Purpose: The purpose of this paper is to develop a framework that explains international activities of open source software (OSS) firms. Design/methodology/approach: This paper reviews relevant literature related to international operations of knowledge-intensive firms, especially in the software industry. Theoretical development is based here on a combination of the network approach, international new venture theory and inward–outward internationalization. Findings: The findings in this study suggest that the international activities of OSS firms can be divided into project activities and business activities. Project activities include inward and outward linkages, and partner identificatio…
