Valmiuksia tulevaisuuden työelämään simulaatiopelioppimisen kautta

2021

Tänä päivänä työtä tehdään yhä useammin hajautetuissa di-gitaalisissa ympäristöissä, joissa yhteisöllisten digitaalistenja 21. vuosisadan taitojen merkitys korostuu. Myös liike-toimintaosaamista tarvitaan tänä päivänä laajalti eri aloilla.Dynaamisten ja monitahoisten ilmiöiden oppiminen tapah-tuu parhaiten aidon kaltaisissa oppimisympäristöissä, kutensimulaatiopeliympäristöissä. Tutkimusaineistomme koostuusimulaatiopeliympäristössä toteutetun korkeakoulukurssinopiskelijoiden reflektiivisistä esseistä. Tutkimuksen tulostenperusteella voidaan esittää, että tapauksemme kaltaisen si-mulaatiopeleillä voidaan tukea monipuolisesti työelämäval-miuksien kehittymistä Work is increasingly being conduc…

Surrogate-assisted multicriteria optimization: Complexities, prospective solutions, and business case

2017

Complexity in solving real-world multicriteria optimization problems often stems from the fact that complex, expensive, and/or time-consuming simulation tools or physical experiments are used to evaluate solutions to a problem. In such settings, it is common to use efficient computational models, often known as surrogates or metamodels, to approximate the outcome (objective or constraint function value) of a simulation or physical experiment. The presence of multiple objective functions poses an additional layer of complexity for surrogate-assisted optimization. For example, complexities may relate to the appropriate selection of metamodels for the individual objective functions, extensive …

Gradient and Lipschitz Estimates for Tug-of-War Type Games

2021

We define a random step size tug-of-war game and show that the gradient of a value function exists almost everywhere. We also prove that the gradients of value functions are uniformly bounded and converge weakly to the gradient of the corresponding $p$-harmonic function. Moreover, we establish an improved Lipschitz estimate when boundary values are close to a plane. Such estimates are known to play a key role in the higher regularity theory of partial differential equations. The proofs are based on cancellation and coupling methods as well as an improved version of the cylinder walk argument. peerReviewed

On the local and global regularity of tug-of-war games

2018

This thesis studies local and global regularity properties of a stochastic two-player zero-sum game called tug-of-war. In particular, we study value functions of the game locally as well as globally, that is, close to the boundaries of the game domains. Furthermore, we formulate a continuous time stochastic differential game and discuss, among other things, the equicontinuity of the families of value functions. The main motivation is to understand the properties of the games on their own right. As applications, we obtain an existence and a regularity result for a nonlinear elliptic p-Laplace type partial differential equation and a characterization of the solution to a parabolic p-Laplace typ…

Asymptotic Lipschitz regularity for tug-of-war games with varying probabilities

2018

We prove an asymptotic Lipschitz estimate for value functions of tug-of-war games with varying probabilities defined in $\Omega\subset \mathbb R^n$. The method of the proof is based on a game-theoretic idea to estimate the value of a related game defined in $\Omega\times \Omega$ via couplings.

Diagnostic Challenges and Surgical Strategies in Ossification of the Posterior Longitudinal Ligament. Case Study

2021

W artykule przedstawiono przypadek pacjentki cierpiącej z powodu mielopatii szyjnej wynikającej z nierozpoznanego przez wiele lat skostnienia więzadła podłużnego tylnego (OPLL – ossification of posterior longitudinal ligament) występującego w obrębie szyjnego odcinka kręgosłupa. W pracy, poza przedstawieniem przypadku klinicznego, zaprezentowano także patofizjologię, objawy, metody diagnostyki oraz leczenia tego bardzo rzadkiego w populacji europejskiej schorzenia.

Imputazione di pagamento - Datio in solutum - Quietanza

2017

Il lavoro offre una disamina aggiornata delle principali questioni teoriche e pratiche intorno agli istituti della imputazione del pagamento, della quietanza e della liberazione dalle garanzie. Ideale filo conduttore dell'analisi è costituito dagli adattamenti di questi istituti all'evolversi dei rapporti obbligatori nel segno della sempre più marcata dematerializzazione dei pagamenti

Parental Attitudes toward Videogames at School

2019

Despite research having highlighted the positive outcomes of the use of videogames to learn, their integration into school contexts remains rare. Literature recognizes the importance of user’s technology acceptance to predict the intention to use and the adoption of new technology in several settings. So far, investigations have primarily focused on students’ and teachers’ opinions, while only a few studies have considered the role of parents. This study aimed to investigate the role of the dimensions of the technology acceptance model on parental preference (254 Italian parents) for the adoption of videogames in primary or secondary schools. Results revealed that 71% of the variance of par…

Partial-order reduction for parity games and parameterised Boolean equation systems

2022

AbstractIn model checking, reduction techniques can be helpful tools to fight the state-space explosion problem. Partial-order reduction (POR) is a well-known example, and many POR variants have been developed over the years. However, none of these can be used in the context of model checking stutter-sensitive temporal properties. We propose POR techniques for parity games, a well-established formalism for solving a variety of decision problems, including model checking. As a result, we obtain the first POR method that is sound for the full modal $$\upmu $$ μ -calculus. We show how our technique can be applied to the fixed point logic called parameterised Boolean equation systems, which pro…
