The reliability of spanish and german electricity forward prices. Databases and price discovery process
2021
Given the existence of different databases from different sources that offer information on forward electricity prices, the need to compare them arises to guarantee that research results and trading decisions based on them are not sensitive to the database used. We worked with forward electricity prices traded over the counter, closest month to maturity, covering the period from 2010 to 2016 for the Spanish over the counter (OTC) market, and from 2008 to 2016 for the German OTC market. The goal of this paper was to test whether there were significant discrepancies between the price series provided by two of the main agencies of financial information (Thomson Reuters and Bloomberg), as well …
Dokumentu meklēšanas sistēma
2022
Bakalaura darbs ir veltīts dokumentu meklēšanas problēmai, kas tiek risināta izmantojot dokumentu indeksa struktūru. Darba ietvaros ir izpētītas un izanalizētas dažādas datu struktūras, kas sniedz iespēju indeksēt dokumentus. Aprakstītās datu struktūras tiek definētas izmantojot klašu diagrammas un to darbības principi tiek attēloti uz konkrētiem piemēriem izmantojot instanču diagrammas. Ir aprakstītas, notestētas un optimizētas autora realizētas programmas datu struktūru izveidošanai un arī dokumentu meklēšanai. Darbā ir pamatoti un ar testēšanas rezultātiem pierādīti ātrdarbības ziņā efektīvākie varianti indeksa struktūras izveidošanai un meklēšanai tajā. Tika aprakstīti programmu realizā…
Flow characteristics of a channelized debris-flow and implications in numerical modelling: a study case
2012
As it is known, debris flows are characterized by extreme propagation rapidity and by the ability to move high quantity of fluid mass. Furthermore, debris flows are fluid enough to travel long distances and, thus, to cause damage in vast areas, even far from the trigger ones. Debris-flow runout estimations are important for the delineation of potentially hazardous areas. Especially in recent years, several researches have been conducted in order to define predicitive models. But, existing runout estimation methods need input parameters that can be difficult to estimate. Recent advances in theory and in experimental research have allowed the assessment of the physics of the debris flows. On …
Search for heavy neutrinos with the T2K near detector ND280
2019
This paper reports on the search for heavy neutrinos with masses in the range 140<MN<493 MeV/c2 using the off-axis near detector ND280 of the T2K experiment. These particles can be produced from kaon decays in the standard neutrino beam and then subsequently decay in ND280. The decay modes under consideration are N→ℓ±απ∓ and N→ℓ+αℓ−β(−)ν(α,β=e,μ). A search for such events has been made using the Time Projection Chambers of ND280, where the background has been reduced to less than two events in the current dataset in all channels. No excess has been observed in the signal region. A combined Bayesian statistical approach has been applied to extract upper limits on the mixing elements of heav…
Predicting the availability of users' devices in Decentralized Online Social Networks
2018
The understanding of the user temporal behavior is a crucial aspect for all those systems that rely on user resources for daily operations, such as decentralized online social networks (DOSNs). Indeed, DOSNs exploit the devices of their users to take on and share the tasks needed to provide services such as storing the published data. In the last years, the increasing popularity of DOSN services has changed the way of how people interact with each other by enabling users to connect to these services at any time by using their personal devices (such as notebooks or smartphones). As a result, the availability of data in these systems is strongly affected (or reflected) by the temporal behavio…
Lielo datu un blokķēdes tīkla integrācija
2022
Mūsdienās lielie uzņēmumi un organizācijas plaši izmanto Lielo datu tehnoloģiju, lai uzkrātu, uzglabātu un analizētu datus. Tomēr Lielo datu tehnoloģija saskaras ar dažām problēmām, piemēram, datu vākšana, datu glabāšana, datu drošība, datu koplietošana. Savukārt pasaulē popularitāti gūst jauna decentralizētās datu uzglabāšanas tehnoloģija – blokķēde. Darba ietvaros tiks apskatīts un analizēts, kā blokķēdes un Lielo datu tehnoloģiju integrācija var uzlabot dažas Lielo datu problēmas.
Defensive behavior in healthcare: the role of organizational factors
Defensive medicine occurs when a healthcare practitioner performs treatment or procedure to avoid exposure to malpractice litigation. Being the consequences of such a behavior nefarious both in terms of patient care, healthcare operations and cost, much has been done in terms of research and practice with the aim to reduce the likelihood of its occurrence. Because defensive medicine is strictly related to the doctor perception of the risk of litigation and its legal repercussions, in the last years, jurisprudence and insurance contract studies in healthcare focused on this topic, as well as national laws have been introduced with the goal of contrasting it. This paper argues and demonstrate…
Study Regarding the Effects of Demographic Transition on Labor Market and Public Pension System in Central and Eastern Europe
2020
Abstract Population and the quality of labor force are the “strengths” features’ that ensure socio-economic development of a country. The last decades can be characterized as a transitional period, in which countries of European Union and especially the countries of Central and Eastern Europe are facing a demographic decline. Reduced birth rate, ageing and migration are factors’ which create a lot of pressure, both on labor market and public pension systems, items correlated with the population structure. In this paper we have presented the demographic situation and the size of migration in five countries of Central and Eastern Europe. The direct linkage between population structure, labor …
Latvijas ģimenes paaudzēs, 2018
2019
Pētījums aptver visas vecuma grupas: gan jaunus cilvēkus patstāvīgās dzīves sākumā (no 18 gadu vecuma), gan pieredzes bagātus — citās vecuma grupās (līdz 79 gadu vecumam), sniedzot precīzu informāciju par cilvēka dzīves galvenajiem demogrāfiskajiem notikumiem un cikliem vairāku paaudžu dzīvē, sākot jau no 1950. gadu vidus.

Tietämätön opettaja demokratiakasvatuksessa
2021
Tämä artikkeli tutkii ranskalaisajattelija Jacques Rancièren älyjen tasa-arvon käsitettä sekä tasa-arvon periaatetta demokratiakasvatuksessa. Artikkelin kollaboratiivinen empiirinen aineisto koostuu 19 opettajaopiskelijan sekä heidän opettajanaan toimineen kirjoittajan autoetnografisista teksteistä yhden lukuvuoden mittaisen kurssin ajalta. Kirjoittajan kokoama ja kertoma moniääninen autoetnografinen tarina tuo esiin erilaisia näkökulmia opettajuuteen ja opettajaksi kasvamiseen, joita peilataan Rancièren ajatteluun. Artikkeli valottaa Rancièren filosofian antia demokratiakasvatukselle ja konkretisoi Rancièren käsitteitä. Lisäksi artikkeli jäsentää älyjen tasa-arvoa autoetnografisen tutkimus…
