Incentive Mechanism for Edge Computing-Based Blockchain: A Sequential Game Approach
2022
The development of the blockchain framework is able to provide feasible solutions for a wide range of Industrial Internet of Things (IIoT) applications. While the IIoT devices are usually resource-limited, how to make sure the acquisition of computational resources and participation of the devices will be the driving force to realize blockchain. In this work, an edge computing-based blockchain framework is considered, where multiple edge service providers (ESPs) can provide computational resources to the IIoT devices. We focus on investigating the trading between the devices and ESPs, where ESPs are the sellers and devices are the buyers. A sequential game is formulated and by exploring the…
Ei-yhteistoiminnallisten pelien sovelluksia langattomissa verkoissa
2011
Laitinen, Jouni Ei-yhteistoiminnallisten pelien sovelluksia langattomissa verkoissa Jyväskylä: Jyväskylän yliopisto, 2011, 36 s. Tietojenkäsittelytiede, kandidaatin tutkielma Ohjaaja: Hirvonen, Pertti Peliteorian suosio on viime vuosina kasvanut uusien sovellusten myös. Näihin sovelluksiin kuuluu myös langattomat tietoverkot ja niissä tapahtuvat kanssakäynnit. Peliteorian avulla näitä tapahtumia voidaan analysoida tarkemmin ja niiden tehokkuutta nostaa. Tässä kirjallisuuteen pohjautuvassa kandidaatin tutkielmassa esitellään ensin peliteorian perusteita, joita sitten sovelletaan langattomien tietoverkkojen eri ongelmiin. Näitä ongelmia ovat: lähetystehon määrittäminen, taajuuden vaihtaminen …
Asymptotic Hölder regularity for the ellipsoid process
2020
We obtain an asymptotic Hölder estimate for functions satisfying a dynamic programming principle arising from a so-called ellipsoid process. By the ellipsoid process we mean a generalization of the random walk where the next step in the process is taken inside a given space dependent ellipsoid. This stochastic process is related to elliptic equations in non-divergence form with bounded and measurable coefficients, and the regularity estimate is stable as the step size of the process converges to zero. The proof, which requires certain control on the distortion and the measure of the ellipsoids but not continuity assumption, is based on the coupling method.
The stigma of feminism: disclosures and silences regarding female disadvantage in the video game industry in US and Finnish media stories
2021
This article examines how the issue of gender, particularly women’s (under)representation in the video game industry, is framed in US and Finnish media. Building on the notion of stigma surrounding feminism, the article examines discourse practices as acts of managing the image of feminism. The findings illustrate five stigma management strategies that offer the possibility of maintaining socially accepted ways of discussing gender inequality and portraying women in mainstream media. Using critical discourse analysis, the paper addresses how the use of these stigma management strategies connects with different contemporary feminisms. The strategies used and their ideological backgrounds var…
The quality of life in the Finnish game industry
2013
Tässä tutkimuksessa tutkitaan työntekijöiden elämänlaatua Suomen peliteollisuudessa. Tutkimus perustuu International Game Developers Associationin (IGDA) vastaavanlaiseen tutkimukseen, joka toteutettiin huhtikuussa 2004. Tavoitteena on tarkastella ongelmia, jotka ovat nähtävissä peliyritysten työympäristössä. Päätavoitteena tässä laadullisessa tapaustutkimuksessa oli selvittää, mitkä ovat yleisiä elämänlaatuun liittyviä ongelmia pelinkehitysyrityksissä ja mitkä olisivat parhaat käytännöt ehkäisemään tai vähentämään elämänlaatuun liittyviä ongelmia. Tutkimuksen tulokset osoittavat, että suomalaisella pelialalla on tällä hetkellä pula osaavista työntekijöistä. Vaikka peliteollisuus on nopeast…
Service Provisioning and User Association for Heterogeneous Wireless Railway Networks
2017
In addition to comforting passengers' journey, the modern railway system is responsible to support a variety of on-board Internet services to meet the passenger's demands on seamless service provisioning. In order to provide wireless access to the train, one idea attracting increasing attention is to deploy a series of track-side access points (TAPs) with high-speed data rates along the rail lines dedicated to the broadband mobile service provisioning on board. Due to the heavy data traffic flushing into the base stations (BSs) of the cellular networks, TAPs act as a complement to the BSs in data delivery. In this paper, we focus on the TAP association problem for service provisioning in a …
Service Provisioning with Multiple Service Providers in 5G Ultra-dense Small Cell Networks
2015
In this work, a game theoretical approach for addressing the virtual network service providers (NSPs), small cell provider (SCP) and user interaction in heterogenous small cell networks is presented. In particular, we consider the users can select the services of different NSPs based on their prices. The NSPs have no dedicated hardware and need to rent from the SCP in term of radio resources, e.g., small cell base stations (SBSs) in order to provide satisfied services to the users. Due to the fact that the selfish parties involved aim at maximizing their own profits, a hierarchical dynamic game framework is presented to address interactive decision problem. In the lower-level, a Stackelberg…
Evolutionary game theory of continuous traits from a causal perspective
2023
Modern evolutionary game theory typically deals with the evolution of continuous, quantitative traits under weak selection, allowing the incorporation of rich biological detail and complicated nonlinear interactions. While these models are commonly used to find candidates for evolutionary endpoints and to approximate evolutionary trajectories, a less appreciated property is their potential to expose and clarify the causal structure of evolutionary processes. The mathematical step of differentiation breaks a nonlinear model into additive components which are more intuitive to interpret, and when combined with a proper causal hypothesis, partial derivatives in such models have a causal meanin…
New insights on the role of ecology and life-history in social evolution
2017
Biological altruism, defined as a behaviour that benefits others at an apparent cost to the focal individual, is found abundantly across different levels of biological organization. While kin selection has been useful for explaining both cooperation and conflict in specialized cooperative societies, more theoretical work has to be done to develop models for realistic ecological and life-history contexts. This thesis aims to fill this gap by providing several new insights on the role of ecology and life-history in various social systems. Firstly, I propose a model that incorporates realistic ecological mechanisms of population regulation and study how different population regulation mechanisms affe…
The carbonates of the Permian Lakes of North Massif central, France
1992
During the Permian, large fluvio-lacustrine basins occurred within the West European Hercynian chain. The deposits were mainly detrital (conglomerates, sandstones and pelites). The two studied sites, Couy borehole and Aumance basin contain several dolomitic beds alternating with pelites containing Ostracods. The carbonate layers constitute various dolomitized facies with dolosparite, laminated and bituminous dolomites, oolites, oncolites and stromatolites, and pedological nodules. Microfacies are varied. The dolomite crystals can be either isolated rhombs scattered in pelites or rhombs and xenomorphic crystals cementing sandstones; in dolomicrites, dolomicrosparites and dolosparites, crysta…
