Sociālo mediju ziņojumu ietekme uz digitālo aktīvu cenu veidošanos: ekonometriskā analīze.
2022
Darba mērķis ir novērtēt Reddit platformas sentimentu, pirmkārt, noskaidrot vai tas statistiski nozīmīgi ietekmē digitālo aktīvu Decentraland, Tezos vai Chiliz vērtību. Otrkārt, noteikt vai sociālo mediju ietekme atšķiras šiem neaizvietojamajiem tokeniem un kriptovalūtai Ethereum. Pētījums veikts par 2021. gada Reddit platformā publicētajiem ziņojumiem. Tāpat analīzei tika lejuplādēti digitālo aktīvu Decentraland, Tezos, Chiliz un Ethereum monētu tirgus dienas dati no Yahoo! Finance tīmekļa vietnes, tādējādi iegūstot 361 gadījumu par katru no aktīviem. Ziņojumu polaritātes noteikšanai tika izmantots VADER klasifikators. Ar lineāras regresijas palīdzību tika novērtēts, vai pastāv attiecības …
Development of a Virtual CH Path on WEB: Integration of a GIS, VR, and Other Multimedia Data
2021
Recent advances in computer science allowed people to explore new possibilities for the fruition of CH all around the world. The development of Geographic Information Systems (GIS) in the field of territorial systems and the evolution of Virtual Reality (VR) solutions opened new scenarios for the valorization of cultural goods. At the same time, recent advances in digital photogrammetry and 3D interactive navigation models on WEB-based on WebGL technologies offered new opportunities of digital fruition of CH. Considering this panorama, the presented work shows how the integration of these technologies gives a precious added value to the virtual fruition of CH. In particular, it has been con…
Virtuaalitodellisuuden uusi nousu : Oculus Rift -sovelluskehityksen työkalut
2015
Virtuaalitodellisuudesta ennustetaan seuraavaa suurta ilmiötä ICT-alalla. Monet suuret teknologia-alan yritykset ovat tuomassa virtuaalitodellisuuden mahdollistavia tuotteita markkinoille lähivuosien aikana. Tämä tutkielma tarkastelee tätä ilmiötä ja kartoittaa, mitä pelimoottoreita sovelluskehittäjilllä on käytettävissään Oculus Rift -virtuaalilaseilla toimivien sovellusten kehittämiseen. Valinnanvaraa löytyy jo nyt, ja on odotettavissa, että tulevaisuudessa yhä useampi pelimoottori tukee Oculus Riftiä. Virtual reality is expected to be the next big thing in the ICT sector. A great number of major technology companies have started to develop new head-mounted displays in recent years. This …
A Perspective Review on Integrating VR/AR with Haptics into STEM Education for Multi-Sensory Learning
2022
As a result of several governments closing educational facilities in reaction to the COVID-19 pandemic in 2020, almost 80% of the world’s students were not in school for several weeks. Schools and universities are thus increasing their efforts to leverage educational resources and provide possibilities for remote learning. A variety of educational programs, platforms, and technologies are now accessible to support student learning; while these tools are important for society, they are primarily concerned with the dissemination of theoretical material. There is a lack of support for hands-on laboratory work and practical experience. This is particularly important for all disciplines related …
Virtual Reality Arcades : A Study on Usage Habits with Emphasis on Digital Gaming
2019
Virtual reality (VR) and VR gaming have seen substantial advancement during the recent years both in terms of technological development and the number of users. A notable rise has also occurred in the number of VR arcades. Despite the growing academic interest towards VR and VR gaming, there is still a dearth of understanding on the usage aspects of VR gaming and VR arcades. To address this gap, this study explored the habits of using VR arcades with emphasis on digital gaming. Specific focus was set on investigating differences between gender, age, and physical activity background. The study was exploratory in nature and based on a quantitative analysis of data collected from 126 responden…
Katsaus virtuaalitodellisuuden syöttölaitteiden toteutusteknologioihin
2016
Virtuaalitodellisuuden syöttölaitteista on olemassa julkista tutkimusta varsin niukasti, vaikka ne ovat virtuaalitodellisuudelle korvaamattoman tärkeitä.

A value sensitive ABM of the refugee crisis in The Netherlands
2019
We develop an agent based model to characterize the wellbeing of newcomers (i.e. asylum seeking refugees) in the context of asylum logistics using Schwartz’s theory of values. The model produces recommendations for decision-makers with respect to avoiding catastrophic outcomes and maximizing best case outcomes. We conduct analysis to show that while a relatively simple set of conditions is necessary to avoid catastrophic outcomes, these conditions are insufficient to maximize the best case outcomes. Furthermore, the conditions that maximize one best case outcome do so at the expense of another. The result is a platform for decision-makers to understand tradeoffs in policies for government a…
Agent-based modelling of values: the case of value sensitive design for refugee logistics
2020
We have used value sensitive design as a method to develop an agent-based model of values in humanitarian logistics for refugees. Schwartz's theory of universal values is implemented in the model in such a way that agents can make value trade-offs, which are operationalized into a measure of refugee wellbeing and a measure of public opinion about how the refugee logistics is being handled. By trying out different ‘value-scenarios’, stakeholders who are responsible for, or involved in refugee logistics can have insights into the effects of various value choices. The model is visualized and made usable as a platform (interactive website) for decision-makers to understand the trade-offs in pol…
