Performance Analysis of Cooperative V2V and V2I Communications Under Correlated Fading
2019
Cooperative vehicular networks will play a vital role in the coming years to implement various intelligent transportation-related applications. Both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications will be needed to reliably disseminate information in a vehicular network. In this regard, a roadside unit (RSU) equipped with multiple antennas can improve the network capacity. While the traditional approaches assume antennas to experience independent fading, we consider a more practical uplink scenario where antennas at the RSU experience correlated fading. In particular, we evaluate the packet error probability for two renowned antenna correlation models, i.e., cons…
Play and liberty : A brief incursion into some ideological currents in the history of systems‐oriented family therapy
2022
We reflect on family therapy and its history from two points of view, as an entity that becomes understood with the help of a twofold concept of a game, and a twofold concept of liberty. Systemic family therapy has always been comprehended with the help of game theory. Its development becomes more properly understood if we keep in mind that game itself is a dualistic concept entailing both a cultural and a logico-mathematical interpretation of a game. We show how cultural ethos has molded the ways how game metaphor have been implemented to systemic thinking. In the same manner we show how Isaiah Berlin's idea of two incompatible concepts of liberty helps to contextualize family therapy in a…
Computer game as a pragmatic concept : ideas, meanings, and culture
2020
This article discusses the ‘computer game’ as a pragmatic concept. A dual nature of the computer game as both a pragmatic idea and a pragmatic meaning is introduced. Practical meanings of the computer game correspond with the concrete effects that engaging with computer games produces in an individual. Practical ideas of the computer game correspond with the subjectively constituted conceptual families concerning the computer game’s assumed practical meaning. Individual computer games can be considered flat or round depending on the range of their practical meanings. Thus, the article contributes to the study of cultural objects by offering a framework for examining the evolution and existe…
Morality in Let’s Play narrations : Moral evaluations of Gothic monsters in gameplay videos of Fallout 3
2018
Performative Let’s Play gaming videos are a part of contemporary Internet culture through which morality becomes shared. Many digital games draw on Gothic traditions to feature human-like monsters who demand morally complex interpretations from players. This study examines what kinds of moral evaluations players form of ambiguous Gothic monsters in Let’s Play videos of the action role-playing game Fallout 3. With a discourse analysis of transcribed speech obtained from 20 Let’s Play series on YouTube, it argues that the moral evaluations that players actively produce impact significantly on the play experience, that players take diverse moral stances whose (in)determinacy varies based on w…
Mikromanageroinnin toteuttaminen StarCraft-reaaliaikastrategiapeliin geneettisellä ohjelmoinnilla muodostettujen potentiaalikenttien avulla
2015
Tämä tutkielma selvittää geneettisen ohjelmoinnin sovellettavuutta sellaisten potentiaalikenttien optimointiin, jotka ohjaavat taistelussa reaaliaikastrategiapelien yksiköi- den mikromanagerointia. Tutkimusympäristönä käytetään StarCraft-peliä. Sovellettavassa menetelmässä pelin yksiköiden ohjaaminen potentiaalikentillä tapahtuu siten, että pelin koh- teet: omat yksiköt, vihollisen yksiköt ja pelialueen ulkoreunat, aiheuttavat kukin potentiaa- likentän. Omia yksiköitä liikutetaan siihen suuntaan, jossa kohteiden potentiaalikenttien yh- teisvaikutus on voimakkain. Geneettistä ohjelmointia käytetään optimoimaan eri kohteiden luomien potentiaalikenttien voimakkuutta määrittäviä funktioita. Men…
Uniform measure density condition and game regularity for tug-of-war games
2018
We show that a uniform measure density condition implies game regularity for all 2 < p < ∞ in a stochastic game called “tug-of-war with noise”. The proof utilizes suitable choices of strategies combined with estimates for the associated stopping times and density estimates for the sum of independent and identically distributed random vectors. peerReviewed
Strontium and argon isotopic homogenization of pelitic sediments during low-grade regional metamorphism: The pan-African upper Damara sequence of Nor…
1979
Abstract The fine mineral fractions extracted from pelitic sediments of the Eocambrian upper Damaran Mulden Group were subjected to a detailed isotopic study by the Rb-Sr and K-Ar methods in combination with a mineralogical analysis by X-ray diffractometry. The sediments contain two major parageneses of metamorphic origin which can be related to two separate low-grade regional metamorphic events of anchizonal intensity with temperatures between 250 and 300°C and pressures up to 2 kbar. These events are dated at about 535 m.y. and 455 m.y. respectively (with λ( 87 Rb) = 1.42 × 10 −11 yr −1 ). Anomalously high K-Ar ages on samples from specific stratigraphic horizons can be related to open sy…
Value Creation and Power Asymmetries in Digital Ecosystems : A Study of a Cloud Gaming Provider
2020
Digital platforms connecting users and service providers have a central role in determining the value creation structure of ecosystems. Platform developers try to achieve a dominant position for the platform with a strong ecosystem around it. The size and attractiveness of the services can attract new users, and growing user volume can bring new co-operative service providers to the service partner network. An interesting question is how the presence of power and potential power asymmetry affect the value creation capability and the structure of a network around a platform? This chapter describes an example of value creation and the influence of power asymmetry in a digital ecosystem built …
Introduction to Expanding Universes : Exploring Games and Transmedial Ways of World-building
2018
Transmedia is a wide concept, as by definition, it is a network of various media forms. It includes also games, both digital and more traditional forms of games. Transmedia productions are often built around a certain television series, but in some cases a digital game has been the core production as well. Games, however, have not been looked at in detail in their role as a part of a transmedia whole. It is important to pay attention to the specificity of games as a media form, to their product-audience relation, and to the way how they incorporate playfulness into that relation. Even in cases where games are just a minor part of the production, the playfulness involved in transmedia user p…
