Effect of voltage deviations on power distribution losses in presence of DG technology
2015
Integration of distributed generation (DG) units in power distribution network has become increasingly attractive multi-faceted paradigm as economic and environmental factors drive new technologies to be more efficient and less polluting than their earlier counterparts. The installation of DGs impacts critically on the planning and operating characteristics of the distribution network. Type, location, number and capacity of DG are essential factors for studying the effect of DGs on the system behavior. In this paper the effect of DG on the power losses of a distribution network is investigated for different types of DG units. Also, the impact of DG on the voltage profile is demonstrated bef…
Scheduling a cellular manufacturing system with GA
2002
The flexible manufacturing cell scheduling problem is considered with a multi-objective approach, pursuing together makespan minimisation and the in process job wait minimisation. The formulation of the scheduling problem is discussed, analysing how to generate well suited sequences, like generalised permutation sequences, and the proper construction of a JIT timing of activities. An evolutionary sequencing algorithm based on both classic genetic operators and hybrid operators is then proposed. The hybrid operators have been introduced to construct highly fit initial population, to perform periodically a local search on the population and to maintain enough genetical diversity in the actual…
Customisation as a solution to misalignment between ERP system and business processes in SME context
2018
Toiminnanohjausjärjestelmät (ERP järjestelmät) luokitellaan ohjelmistopaketeiksi, jotka on tehty standardoiduksi järjestelmiksi yrityksien toiminnan ohjaamiseen. Ne eivät kuitenkaan aina vastaa täydellisesti yrityksien tarpeita ja siten johtavat epäyhteensopivuuteen yrityksen prosessien ja ERP järjestelmän kanssa. Ratkaisuksi tähän epäyhteensopivuuteen on usein esitetty yrityksen prosessien muokkaamista vastaamaan toiminnanohjausjärjestelmää. Nämä samat prosessit ja niiden erilaisuus on kuitenkin todettu olevan tärkeitä ominaisuuksia pienissä ja keskisuurissa yrityksissä. ERP järjestelmät ovat monella tapaa hyödyksi pienille ja keskisuurille yrityksille. Yleisesti todetaan, että yrityksien …
Sähköiset tunnistustyökalut lisäävät etäopiskelumahdollisuuksia
2019
TeSLA-hankkeen tavoitteena oli monipuolistaa ja parantaa verkko-opiskelumahdollisuuksia eurooppalaisissa korkeakouluissa kehittämällä työkaluja, jotka tunnistavat sekä etäopiskelijan että opintosuorituksen tekijyyden ja mahdollistavat monenlaisia luotettavia arviointi- ja palautteenantotapoja. Hankkeessa kehitetty sähköinen TeSLA-arviointijärjestelmä mahdollistaa opiskelijan tunnistamisen kasvojen, äänen ja näppäilyn perusteella sekä varmistaa suoritusten tekijyyden analysoimalla kirjoitustyyliä ja tunnistamalla plagioinnin. Kolmen laajan pilottikierroksen aikana seitsemässä eurooppalaisessa yliopistossa yhteensä noin 20 000 opiskelijan testaama TeSLA-järjestelmä lisää valmistuttuaan merkit…

Incorporating teacher-student dialogue into digital course material : Usage patterns and first experiences
2020
This work-in-progress research investigates teacher-student communication via Learning Management Systems (LMS) in highly populated courses. An LMS called TIM (The Interactive Material) includes a specific commenting technology that attempts to make teacher-student dialog effortless. The research goal is to explore students’ willingness to use the technology and identify patterns of usage. To these ends, a survey with both Likert and open-ended questions was issued to CS1 and CS2 students. A favorable student evaluation was observed while several critical viewpoints that inform technology development were revealed. We noticed that besides appreciating the possibility of making comments, man…
Optimisation of Conditions for Extraction of Biologically Active Compounds from Common Bryophytes in Latvia / Latvijâ Augoðu Briofîtu Ekstrakcijas Ap…
2015
Abstract Bryophytes are the second largest taxonomic group in the plant kingdom. They contain a high number of biologically active compounds. Studies of their composition are important for understanding evolutionary processes in the plant kingdom. The aim of this study was to assess bryophyte secondary metabolite extraction options and to increase the yields of polyphenols and substances determining the free radical scavenging activity of bryophyte extracts. Similar studies have been conducted using higher plants as model organisms, but not using bryophytes. Comparison of five extraction methods (conventional, Soxhlet extraction, treatment with microwaves, ultrasound, and supercritical CO2 …
Optimisation d’un modèle atmosphérique transnational de prédiction de la concentration journalière d’ozone : intégration de paramètres météorologique…
2021
International audience; L'ozone (O3) est un polluant atmosphérique secondaire formé lors de réactions photochimiques, en présence de précurseurs (NOx, COV, CO). L'exposition à l'O3 est délicate à modéliser car ce polluant présente une forte variabilité spatiotemporelle. Le but des présents travaux est d'optimiser l'évaluation des concentrations journalières d'O3 modélisées à échelle kilométrique, à l'aide de modèles MARS et de données météorologiques. La plateforme de modélisation PREVEST a généré une prédiction de concentrations maximales journalières d'O3 pour un maillage de 3km de côté. La station de mesure de la qualité de l'air du réseau ATMO-Bourgogne-Franche-Comté, Besançon-Prévoyanc…
Detecting Asset Misappropriation: Forensic Accounting
2021
The main task of the investigation of asset misappropriation is the correct classification of a crime: identification of the fact of misappropriation and determination of the amount of misappropriated assets. Specificity of asset diversity, asset accounting requirements, and a wide range of misappropriation opportunities require specialised knowledge in accounting and economics that investigators often lack. The aim of the study is to increase the knowledge of investigators in forensic accounting in order to increase effectiveness of investigations in detecting asset misappropriation. In this article, the authors, Latvian and Lithuanian accounting experts, talk about typologies of asset mis…
L'optimisation fusion - confusion : une synthèse privilégiée du droit et du chiffre
2010
It is not always easy to dissociate, in the settlement problems, tax and accounting, the main thing and the ac cessory. Generally, mergers are in this case, simplified mergers and universal transmissions, too. When professionals want, in this field, to optimize integrated, legal choices - tax - accounting, it is often obliged to treat the problem, without assistanc e. This autonomy look that this subject is at the crossroads of several disciplines and it is necessary to compose, without really opposing them. The field of mergers and confusion is a good synthesis of the link Law - management. The company which wishes to absorb its 100 % subsidiary can choose between simplified fusion and dis…
