ValWorkBench: an open source Java library for cluster validation, with applications to microarray data analysis.
2015
Background: Cluster analysis is one of the most well known activities in scientific investigation and the object of research in many disciplines, ranging from statistics to computer science. It is central to the life sciences due to the advent of high throughput technologies, e.g., classification of tumors. In particular, in cluster analysis, it is of relevance to assess cluster quality and to predict the number of clusters in a dataset, if any. This latter task is usually performed via internal validation measures. Despite their potentially important role, both the use of classic internal validation measures and the design of new ones, specific for microarray data, do not seem to have grea…
Area-Based Depth Estimation for Monochromatic Feature-Sparse Orthographic Capture
2018
With the rapid development of light field technology, depth estimation has been highlighted as one of the critical problems in the field, and a number of approaches have been proposed to extract the depth of the scene. However, depth estimation by stereo matching becomes difficult and unreliable when the captured images lack both color and feature information. In this paper, we propose a scheme that extracts robust depth from monochromatic, feature-sparse scenes recorded in orthographic sub-aperture images. Unlike approaches which rely on the rich color and texture information across the sub-aperture views, our approach is based on depth from focus techniques. First, we superimpose shifted …
A Review on Approaches for Condition Based Maintenance in Applications with Induction Machines located Offshore
2012
Published version of an article in the journal: Modeling, Identification and Control. Also available from the publisher at: http://dx.doi.org/10.4173/mic.2012.2.4 Open access This paper presents a review of different approaches for Condition Based Maintenance (CBM) of induction machines and drive trains in offshore applications. The paper contains an overview of common failure modes, monitoring techniques, approaches for diagnostics, and an overview of typical maintenance actions. Although many papers have been written in this area before, this paper puts an emphasis on recent developments and limits the scope to induction machines and drive trains applied in applications located offshore.
A framework for intention-driven requirements engineering of innovative software products
2011
Requirements engineering is highly challenging particularly when designing innovative software products. This is so because there are no corresponding products, ultimate needs of actors are difficult to capture, the products may have unforeseeable impacts on the actors’ behavior, and it is hard to find out how value-added and competitive the product actually is. In this paper, we propose a novel framework for intention-driven requirements engineering of innovative software products, which combines technological, social and business viewpoints. We illustrate its use with a short example related to the domain of web mapping services and augmented reality. peerReviewed
Embracing iterations in Quantum software: a vision
2022
In today’s software engineering, iterations, affordable en masse, form an important part of just about any system. However, not all computing resources are cheap to consume. In High-Performance (HPC) and Quantum Computing (QC), executions can consume considerable amounts of energy and time, which is reserved and used even if the very first steps in the process fail. This means that developers must assume a different attitude towards programming, and aim at error-free software before its execution. This is com monly facilitated using simulators, which are commonplace for both HPC and QC. However the fashion developers advance from one tool to another is ad-hoc, with no established software e…
Web-sovellus ohjelmoijien motivaation ja motivaatio-ongelmien kartoittamiseen ja korjaamiseen
2017
Tämä tutkielma pyrkii antamaan vastauksen siihen, kuinka voidaan toteuttaa www-sovellus, jolla voidaan mitata ja analysoida ohjelmoijien motivaatiota organisaatiossa ja kuinka voidaan laatia motivaatiosuunnitelma heikkojen motivaatioalueiden korjaamiseksi. Työn teoriaosuudessa käsitellään ensin taustateoriaa työtyytyväisyydestä ja motivaatiosta ja käydään läpi eräitä tärkeitä motivaatiomalleja. Tämän jälkeen valitaan kaksi motivaatiomallia, joille laaditaan toiminnalliset määrittelyt, joilla ne on mahdollista muuntaa mitattavaan ja laskettavaan muotoon. Teoriaosuudessa esitetään myös, kuinka motivaatiosuunnitelma tehdään ja kuinka voidaan laatia motivaatiota korjaavia toimenpiteitä. Teoriao…
The Influence of Requirements in Software Model Development in an Industrial Environment
2017
Textual description of requirements is a specification technique that is widely used in industry, where time is key for success. How requirements are specified textually greatly depends on human factors. In order to study how requirements processing is affected by the level of detail in textual descriptions, this paper compares enriched textual requirements specifications with non-enriched ones. To do this, we have conducted an experiment in industry with 19 engineers of CAF (Construcciones y Auxiliares de Ferrocarril), which is a supplier of railway solutions. The experiment is a crossover design that analyzes efficiency, effectiveness, and perceived difficulty starting from a written spec…
Semantic oriented data structuration for MABS Application to BIM
2013
International audience; This paper presents a multiagent-based simulation approach to qualify the usage of buildings from the design phase. Our approach combines ontology and evolution process based on machine learning algorithms. The ontology relies on semantic data structures for the representation of environment components, agent knowledge and all data generated during the simulation.
Interoperability of B2B Applications
2011
This paper presents a Web-based data integration methodology and tool framework, called X-TIME, for the development of Business-to-Business (B2B) design environments and applications. X-TIME provides a data model translator toolkit based on an extensible meta model and XML. It allows the creation of adaptable semantic-oriented meta models to support the design of wrappers or reconciliators (mediators), taking into account characteristics of interoperable information systems, such as extensibility and composability. X-TIME defines a set of meta types which correspond to g meta level semantic descriptors of data models found in the Web. The meta types are organized in a generalization hierarc…
Business Model Canvas Should Pay More Attention to the Software Startup Team
2020
Business Model Canvas (BMC) is a tool widely used to describe startup business models. Despite the various business aspects described, BMC pays a little emphasis on team- related factors. The importance of team-related factors in software development has been acknowledged widely in literature. While not as extensively studied, the importance of teams in software startups is also known in both literature and among practitioners. In this paper, we propose potential changes to BMC to have the tool better reflect the importance of the team, especially in a software startup environment. Based on a literature review, we identify various components related to the team, which we then further suppor…
