Interactively Learning the Preferences of a Decision Maker in Multi-objective Optimization Utilizing Belief-rules
2020
Many real life problems can be modelled as multiobjective optimization problems. Such problems often consist of multiple conflicting objectives to be optimized simultaneously. Multiple optimal solutions exist to these problems, and a single solution cannot be said to be the best without preferences given by a domain expert. Preferences can be used to find satisfying solutions: optimal solutions, which best match the expert’s preferences. To model the preferences of the expert, and aid him/her in finding satisfying solutions, a novel method is proposed. The method utilizes machine learning combined with belief-rule based systems to adaptively train a belief rule based system to learn a domai…
Linear Types for Higher Order Processes with First Class Directed Channels
1995
Abstract We present a small programming language for distributed systems based on message passing processes. In contrast to similar languages, channels are one-to-one connections between a unique sender and a unique receiver process. Process definitions and channels are first class values and the topology of process systems can change dynamically. The operational semantics of the language is defined by means of graph rewriting rules. A static type system based on the notion of linear types ensures that channels are always used as one-to-one connections.
A replication study on the intuitiveness of programming language syntax
2023
AbstractIn this article, we present a replication of an empirical experiment that evaluates intuitiveness and comprehensibility of keywords relating to different concepts in programming languages, originally conducted by Stefik and Gellenbeck. Novice programmers face many barriers when learning programming. One of these barriers is syntax, which for many languages is not designed based on empirical evidence. The purpose of the experiment was to provide more empirical evidence on the subject, to find out if the results of the original experiment can be replicated and if conducting the experiment in an environment where English is not the native language affects the results. The results of ou…
From Procedures to Objects: A Research Agenda for the Psychology of Object-Oriented Programming Education
2008
Programming education has experienced a shift from imperative and procedural programming to object-orientation. This shift has been motivated by educators’ desire to please the information technology industry and potential students; it is not motivated by research either in psychology of programming or in computer science education. There are practically no results that would indicate that such a shift is desirable, needed in the first place, or even effective for learning programming. Moreover, there has been an implicit assumption that classic results on imperative and procedural programming education and learning apply to object-oriented programming (OOP) as well. We argue that this is n…
An Immersive Motor Protocol for Frailty Rehabilitation
2019
Frailty is a pre-clinical condition that worsens physical health and quality of life. One of the most frequent symptoms of frailty is an increased risk of falling. In order to reduce this risk, we propose an innovative virtual reality motor rehabilitation program based on an immersive tool. All exercises will take place in the CAVE, a four-screen room with a stationary bike. The protocol will include two types of exercises for the improvement of balance: “Positive Bike” and “Avoid the Rocks.” We will choose evaluation scales related to the functional aspects and subjective perception of balance. Our aim is to prove that our innovative motor rehabilitation protocol is as effective as or more…
Automated Checking of Flexible Mathematical Reasoning in the Case of Systems of (In)Equations and the Absolute Value Operator
2021
We present an approach and a tool for automatically providing feedback on solutions that involve complicated reasoning patterns. Currently the tool supports linear systems of equations and inequations that may also contain the absolute value operator and a restricted form of rational functions. This suffices for designing problems that are laborious to solve with standard mechanical procedures, but much easier using short-cuts that students may find by creative thinking. Earlier research has found that struggling with important mathematics promotes conceptual development. Our goal is to encourage students to such struggling. A crucial feature is to give them great freedom to choose the path…
Kvanttikoneohjelmointi
2016
Työssä tutkittiin kvanttiohjelmointikielten nykytilaa. Tavoitteena oli pintapuolisesti kartoittaa millaisia kieliä on olemassa, mitä niiden erot ovat ja miksi niitäonkehitetty,vaikkakäytännönkvanttitietokoneitaeivieläolekaan.Tämätutki- mustavoite toteutui hyvin. Johtopäätöksenä voidaan sanoa, että kvanttiohjelmoin- tikieliä on kehitetty suhteellisen paljon kvanttitietokoneiden puuttumiseen nähden, ja ne eroavat monilta osin. Myös niiden kehittämiseen löydettiin paljon hyviä syitä. In this paper the current state of quantum programming languages was studied. The objective was to do a survey of existing languages, their differences, and the reasons for their development, even though practical…
The territorial dimension in the EU programming and the New Framework for Public Policies: Territorial Tural Development, CAP Reform and new LEADER
2012
Lo que venimos denominando como perspectiva territorial del desarrollo es un fenómeno bastante reciente en el contexto de la Unión Europea, de apenas dos décadas. En esencia esta perspectiva territorial del desarrollo se ha centrado en un enfoque local de los procesos de desarrollo en las áreas rurales, de la mano, principalmente, de instrumentos como LEADER. La necesidad de incorporar la dimensión territorial a los procesos de desarrollo proviene no solo del éxito global de estos instrumentos, sino también por el convencimiento de que puede constituir un elemento fundamental de cara a la cohesión económica y social en el seno de la UE. Avances recientes, como el Libro Verde de la Cohesión …
Standardization of Road Danger Signs in the European Union
2015
The aim of this research is to find a solution for the standardization of road signs in the EU zone by a comparative analysis of different national sign systems to establish a common set from a single country. This work is based on the idea that road sign standardization might increase the safety level of transnational journeys and foster the relationships among the various members of the EU Community. This paper presents the outcome of the first step of the research, which focuses on the harmonization of danger signs. In more detail, a multicriteria approach is applied to rank 19 EU Member States on the basis of three main aspects: the installation cost of new signs, new sign learning issu…
A Roles-Based Approach to Variable-Oriented Programming
2008
Delocalized variable plans pose problems for novice programmers trying to read and write programs. Variable-oriented programming is a programming paradigm that emphasizes the importance of variable-related plans, and localizes actions pertaining to each variable together in one place in the program code. This paper revisits the idea of variable-oriented programming and shows how it can be founded on roles of variables: stereotypes of variable use suitable for teaching to novices. The paper sketches out how variable-oriented, roles-based programming could be implemented using either a new programming language or a framework built on an existing language. The possible applications, merits, an…
