Protocolo de comunicación trabajador-robot mediante imágenes

La idea del proyecto viene del concepto de “fábricas del futuro”, donde las barreras entre robots y humanos se rompen para que la colaboración entre ambos sea como en un equipo. Para la realización de este proyecto se ha utilizado el brazo robótico IRB120 de la marca ABB de 6 Grados de libertad, Matlab y el software Robot Studio. El Objetivo principal de este proyecto es establecer el protocolo de comunicación trabajador-robot mediante imágenes. El trabajador debería poder controlar el robot mediante dibujos realizados en la mesa de trabajo. En el desarrollo de la comunicación trabajador-robot cabe distinguir tres partes: · El análisis y tratamiento de imágenes para el cual se ha utilizado el software Matlab. · Transmisión de los datos desde Matlab al robot. · Programación de las acciones a realizar por el robot mediante el software “Robot Studio”. Con el protocolo de comunicación desarrollado y las imágenes realizadas por el trabajador el robot es capaz de detectar lo siguiente: · la herramienta que debe utilizar (rotulador, boli o ventosa) · si lo que tiene que dibujar en la mesa de trabajo son puntos o trazo continuo. · la localización de los puntos o del trazo continuo en la mesa de trabajo. Se ha alcanzado el objetivo propuesto con éxito, el protocolo de comunicación trabajador-robot mediante imágenes ha sido establecido. Mediante el análisis y tratamiento de imágenes se puede conseguir la información necesaria para que el robot pueda ejecutar las acciones requeridas por el trabajador.

Lähiverkkotuotteen palveluprosessien kehittäminen, Case: Elisa

Diplomityön aiheena oli tutkia case-yrityksen prosessikehitystä, prosessijohtamista sekä lähiverkkopalveluketjua prosessinäkökulman kannalta. Tutkimuksen päätavoitteina oli selvittää, kuinka lähiverkkopalveluketjun toimintaa voisi tehostaa, ja minkälaisia kertakustannuksia yhdestä keskiverotoimituksesta syntyy. Tavoitteina oli myös selvittää yrityksen prosessikehittämisen tila sekä minkälaisia prosessijohtamismalleja yrityksessä käytetään ja millä tavoin sen pääprosesseja johdetaan. Tutkimus oli case-tyyppinen, eli siinä tutkittiin yhden yrityksen toimintaa ja prosesseja. Teoreettinen pohja tutkimukselle luotiin käsittelemällä liiketoimintaprosesseihin liittyviä ydinmääritelmiä, erilaisia prosessijohtamismalleja ja liiketoimintaprosessien mittaamista. Tutkimuksen peruselementit tiedon hankintaan olivat kirjallisuus ja haastattelut. Lisäksi tutkimus pohjasi vahvasti tutkijan tekemiin omiin havaintoihin yrityksessä ja sen toimintaympäristössä. Tutkimuksen ensimmäisessä vaiheessa kartoitettiin lähiverkkopalveluketjun senhetkinen tilanne, analysoitiin palveluketjun sisältämiä prosesseja ja kirjattiin ylös havaitut ongelmakohdat. Haastatteluista kerättyjen tietojen perusteella laskettiin yhdestä keskivertolähiverkkotoimituksesta case-yritykselle syntyvät kertakustannukset. Tämän lisäksi analysoitiin yrityksen senhetkistä prosessijohtamis- ja prosessikehitystasoa sekä peilattiin niitä yrityksen tulevaisuuden prosessikehittämistoimiin. Lopuksi johtopäätöksien kautta esitettiin kaksi toimintaehdotusta, joilla palveluketjun toimintaa voitaisiin parantaa. Ensimmäinen ehdotus oli radikaalimpi, ja siinä siirryttäisiin kokonaan pois palveluketjumallista tiimipohjaiseen malliin. Toisessa ehdotuksessa keskityttiin korjaamaan palveluketjun ongelmakohtia.

Merimies on erimies? Organisaatiositoutuminen suomalaisessa risteilyvarustamossa. Case: Kristina Cruises Oy

Tutkimuksen tavoitteena on selvittää, miten organisaatioon sitoutuminen moniulotteisena käsitteenä ymmärretään yrityksen johtoryhmässä ja avainesimiesten kesken, kun työpaikkana on risteilyvarustamo ja -laiva. Tutkimuksen empiirisen aineiston muodostaa viisi haastattelua laivan palveluosastoilta sekä yrityksen johtoryhmän haastattelut. Teoriaosuudessa on keskitytty kuvailemaan sitoutumiseen vaikuttavia tekijöitä ottaen huomioon kohdeorganisaation toimintaympäristö. Tässä tutkimuksessa organisaatiositoutuminen ymmärretään yksilön henkilökohtaisten tarpeiden, tunnepitoisen kiinnittymisen ja työyhteisön vaikutuksen yhteenliittymänä. Tutkimus on laadullinen ja aineiston keräystapana on käytetty pääasiallisesti teemahaastattelua. Aineistoa on täydennetty muutamalla avoimella sähköpostikyselyllä. Analysointi tapahtui teemoittelun avulla, josta johtopäätöksiin edettiin induktiivisesti. Tutkimustulosten perusteella voidaan todeta, että organisaatiositoutuminen kohdeyrityksessä on ymmärretty lähes samalla tavalla sekä johtoryhmän että esimiesten kesken. Huomioon otettavia aiheita sitouttamista silmällä pitäen ovat yrityksen arvojen ja tavoitteiden merkitys läpi koko sitoutumisprosessin.

Polychlorinated dibenzo-p-dioxins (PCDD), dibenzofurans (PCDF) and polychlorinated biphenyls (PCB): main sources, environmental behaviour and risk to man and biota

Polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofuranes (PCDF) and polychlorinated biphenyls (PCB) are types of persistent and bioaccumulating organic pollutants with enhanced chronic toxicity and carcinogenic properties and can be considered as environmental indicators of anthropogenic activities since their occurrence in the environment can always be linked to anthropogenic activities. The present paper reviews the main sources and behaviour of these compounds in the environment as well as the risks they represent to man and biota.

Defining a Performance Measurement System for Technology Marketing Team by Using the Balanced Scorecard Method

This thesis was produced for the Technology Marketing unit at the Nokia Research Center. Technology marketing was a new function at Nokia Research Center, and needed an established framework with the capacity to take into account multiple aspects for measuring the team performance. Technology marketing functions had existed in other parts of Nokia, yet no single method had been agreed upon for measuring their performance. The purpose of this study was to develop a performance measurement system for Nokia Research Center Technology Marketing. The target was that Nokia Research Center Technology Marketing had a framework for separate metrics; including benchmarking for starting level and target values in the future planning (numeric values were kept confidential within the company). As a result of this research, the Balanced Scorecard model of Kaplan and Norton, was chosen for the performance measurement system for Nokia Research Center Technology Marketing. This research selected the indicators, which were utilized in the chosen performance measurement system. Furthermore, performance measurement system was defined to guide the Head of Marketing in managing Nokia Research Center Technology Marketing team. During the research process the team mission, vision, strategy and critical success factors were outlined.

Reactions of Chlorambucil and its main metabolite, Phenylacetic Acid Mustard, with 2’-deoxyribonucleosides and Calf Thymus DNA

Chlorambucil is an anticancer agent used in the treatment of a variety of cancers, especially in chronic lymphocytic leukemia, and autoimmune diseases. Nevertheless, chlorambucil is potentially mutagenic, teratogenic and carcinogenic. The high antitumor activity and high toxicity of chlorambucil and its main metabolite, phenylacetic acid mustard, to normal tissues have been known for a long time. Despite this, no detailed chemical data on their reactions with biomolecules in aqueous media have been available. The aim of the work described in this thesis was to analyze reactions of chlorambucil with 2’-deoxyribonucleosides and calf thymus DNA in aqueous buffered solution, at physiological pH, and to identify and characterize all adducts by using modern analyzing methods. Our research was also focused on the reactions of phenylacetic acid mustard with 2’-deoxynucleosides under similar conditions. A review of the literature consisting of general background of nucleic acids, alkylating agents and ultraviolet spectroscopy used to identify the purine and pyrimidine nucleosides, as well as the results from experimental work are presented and discussed in this doctoral thesis.

The construction of infant and primary school teachers’ identity during their initial professional development and first years of work (Identidoc). Summary, main results and contributions

Educators who are currently beginning their professional career at any level of the educationalsystem and who will likely have to work during the next thirty to forty years will be takingpart in the education of individuals who, with the permission of prophets and doomsayers,will live part of their lives in the 22nd century. That long but simple statement causes a bit ofvertigo as well as a good amount of reflection on the part of we educators who were trainedin the 20th century, are working in the 21st century, and are responsible for preparing peopleto build a tomorrow that is already today (Millán and Sancho, 1995). This is the starting pointof our research groups’ interest in exploring how men and women who have graduated fromteacher education programs with specializations in infant and primary education learn to beteachers, and how they establish and position themselves as teachers during their university studies and the first years of their professional life...

The effects of social networks on work-team effectiveness

This is a study of team social networks, their antecedents and outcomes. In focusing attention on the structural configuration of the team this research contributes to a new wave of thinking concerning group social capital. The research site was a random sample of Finnish work organisations. The data consisted of 499 employees in 76 teams representing 48 different organisations. A systematic literature review and quantitative methods were used in conducting the research: the former primarily to establish the current theoretical position on the relationships among the variables and the latter to test these relationships. Social network analysis was the primary method used in identifying the social-network relations among the work-team members. The first and key contribution of this study is that it relates the structuralnetwork properties of work teams to behavioural outcomes, attitudinal outcomes and, ultimately, team performance. Moreover, it shows that addressing attitudinal outcomes is also important in terms of team performance; attitudinal outcomes (team identity) mediated the relationship between the team’s performance and its social network. The second contribution is that it examines the possible antecedents of the social structure. It is thus one response to Salancik’s (1995) call for a network theory in that it explains why certain network characteristics exist. Itdemonstrates that irrespective of whether or not a team is heterogeneous in terms of age or gender, educational diversity may protect it from centralisation. However, heterogeneity in terms of gender turned out to have a negative impact on density. Thirdly, given the observation that the benefits of (team) networks are typically theorised and modelled without reference to the nature of the relationships comprising the structure, the study directly tested whether team knowledge mediated the effects of instrumental and expressive network relationships on team performance. Furthermore, with its focus on expressive networks that link the workplace to a more informal world, which have been rather neglected in previous research, it enhances knowledge of teams andnetworks. The results indicate that knowledge sharing fully mediates the influence of complementarities between dense and fragmented instrumental network relationships, thus providing empirical validation of the implicit understanding that networks transfer knowledge. Fourthly, the study findings suggest that an optimal configuration of the work-team social-network structure combines both bridging and bonding social relationships.

Rotenoids from Tephrosia toxicaria with larvicidal activity against Aedes aegypti, the main vector of dengue fever

In the search for new larvicides from plants, we have investigated the potential activity of the rotenoids deguelin (1), 12a-hydroxy-α-toxicarol (2) and tephrosin (3), isolated from the bioactive ethanol extract of roots of Tephrosia toxicaria Pers., against Aedes aegypti, the main vector of dengue. The absolute configuration of these compounds was determined by circular dichroism (CD) spectra. The LC50 values of the compounds evaluated justify the potential of T. toxicaria as a new natural larvicide.

Evaluating the success of software development projects in Russia, Ukraine, and Belarus

The size and complexity of projects in the software development are growing very fast. At the same time, the proportion of successful projects is still quite low according to the previous research. Although almost every project's team knows main areas of responsibility which would help to finish project on time and on budget, this knowledge is rarely used in practice. So it is important to evaluate the success of existing software development projects and to suggest a method for evaluating success chances which can be used in the software development projects. The main aim of this study is to evaluate the success of projects in the selected geographical region (Russia-Ukraine-Belarus). The second aim is to compare existing models of success prediction and to determine their strengths and weaknesses. Research was done as an empirical study. A survey with structured forms and theme-based interviews were used as the data collection methods. The information gathering was done in two stages. At the first stage, project manager or someone with similar responsibilities answered the questions over Internet. At the second stage, the participant was interviewed; his or her answers were discussed and refined. It made possible to get accurate information about each project and to avoid errors. It was found out that there are many problems in the software development projects. These problems are widely known and were discussed in literature many times. The research showed that most of the projects have problems with schedule, requirements, architecture, quality, and budget. Comparison of two models of success prediction presented that The Standish Group overestimates problems in project. At the same time, McConnell's model can help to identify problems in time and avoid troubles in future. A framework for evaluating success chances in distributed projects was suggested. The framework is similar to The Standish Group model but it was customized for distributed projects.
