Application Architecture Design for an Industrial Service Company

Työssä oli tavoitteena suunnitella globaali sovellusarkkitehtuuri, joka ohjaa teollisen huoltoyrityksen sovellusten kehitystyötä. Sovellusarkkitehtuuri kuvaa tietokoneohjelmien toiminnallisuuteen loppukäyttäjien näkökulmasta ja sen laatiminen on osa strategista tietojärjestelmäsuunnittelua. Arkkitehtuurin tehtävänä on varmistaa, että tietojärjestelmät suunnitellaan kokonaisuutena tukemaan organisaation toimintaa. Arkkitehtuurin tekemistä ohjasi strategisen tietojärjestelmäsuunnittelun periatteet ja mallit. Tekniikat olivat samoja kuin projektikohtaisessa tietojärjestelmäsuunnittelussa. Sovellusarkkitehtuurin tekeminen alkoi tutustumalla yrityksessä vallitsevaan tilanteeseen sekä liiketoiminta- ja tietotekniikkastrategioihin. Tarkastelun kohteena olivat pääasiassa liiketoimintaprosessit ja käytössä olevat sovellukset. Tutustuminen tapahtui lähinnä haastatteluin ja dokumentteihin tutustumalla. Seuraavaksi johdettiin vaatimukset tulevaisuuden sovelluksille haastatteluista ja edellisen vaiheen materiaalin perusteella. Liiketoiminnan kannalta tärkeimmät vaatimukset valittiin täytettäväksi arkkitehtuurilla. Varsinaisen arkitehtuurin tekeminen oli lähinnä sovellusten valitsemisesta ja niiden keskinäisten suhteiden määrittelyä. Arkkitehtuurin perusteella määritettiin kehityshankeet.

Energy aware software for many-core systems

Many-core systems provide a great potential in application performance with the massively parallel structure. Such systems are currently being integrated into most parts of daily life from high-end server farms to desktop systems, laptops and mobile devices. Yet, these systems are facing increasing challenges such as high temperature causing physical damage, high electrical bills both for servers and individual users, unpleasant noise levels due to active cooling and unrealistic battery drainage in mobile devices; factors caused directly by poor energy efficiency. Power management has traditionally been an area of research providing hardware solutions or runtime power management in the operating system in form of frequency governors. Energy awareness in application software is currently non-existent. This means that applications are not involved in the power management decisions, nor does any interface between the applications and the runtime system to provide such facilities exist. Power management in the operating system is therefore performed purely based on indirect implications of software execution, usually referred to as the workload. It often results in over-allocation of resources, hence power waste. This thesis discusses power management strategies in many-core systems in the form of increasing application software awareness of energy efficiency. The presented approach allows meta-data descriptions in the applications and is manifested in two design recommendations: 1) Energy-aware mapping 2) Energy-aware execution which allow the applications to directly influence the power management decisions. The recommendations eliminate over-allocation of resources and increase the energy efficiency of the computing system. Both recommendations are fully supported in a provided interface in combination with a novel power management runtime system called Bricktop. The work presented in this thesis allows both new- and legacy software to execute with the most energy efficient mapping on a many-core CPU and with the most energy efficient performance level. A set of case study examples demonstrate realworld energy savings in a wide range of applications without performance degradation.

Application for fault location in electrical power distribution systems

Fault location has been studied deeply for transmission lines due to its importance in power systems. Nowadays the problem of fault location on distribution systems is receiving special attention mainly because of the power quality regulations. In this context, this paper presents an application software developed in Matlabtrade that automatically calculates the location of a fault in a distribution power system, starting from voltages and currents measured at the line terminal and the model of the distribution power system data. The application is based on a N-ary tree structure, which is suitable to be used in this application due to the highly branched and the non- homogeneity nature of the distribution systems, and has been developed for single-phase, two-phase, two-phase-to-ground, and three-phase faults. The implemented application is tested by using fault data in a real electrical distribution power system

Dynamics of governance and control in inter-organizational software development

In recent years, development of information systems (IS) has rapidly changed towards increasing division of labor between firms. Two trends are emerging. First, client companies increasingly outsource software development to external service providers. Second, the formerly oligopolistic enterprise application software industry has started to disintegrate into focal partnership networks – so called platform ecosystems. Despite the increasing prominence of IS outsourcing and platform ecosystems, many of these inter-organizational partnerships fail to achieve expected benefits. Ineffective governance and control frequently plays a pivotal role in producing these failures. While designing effective governance and control mechanisms is always challenging, inter-organizational software development projects are often business-critical and exhibit additional dynamics and uncertainty. As a consequence governance and control have to be adapted over time. The three research projects included in this book provide a better understanding of how and why governance and control can be effectively adapted over time. The implications for successful management of inter-organizational software development projects are highly relevant for theory and practice.

An RFID Bulk Cargo Supervising System

In this work, a system using active RFID tags to supervise truck bulk cargo is described. The tags are attached to the bodies of the trucks and readers are distributed in the cargo buildings and attached to weighs and the discharge platforms. PDAs with camera and support to a WiFi network are provided to the inspectors and access points are installed throughout the discharge area to allow effective confirmations of unload actions and the acquisition of pictures for future audit. Broadband radio equipments are used to establish efficient communication links between the weighs and cargo buildings which are usually located very far from each other in the field. A web application software was especially developed to enable robust communication between the equipments for efficient device management, data processing and reports generation to the operating personal. The system was deployed in a cargo station of a Brazilian seashore port. The obtained results prove the effectiveness of the proposed system.

Sistema sem fios para controlo de iluminação decorativa

Este projecto surgiu no contexto da solicitação de um dos clientes da empresa Castros Iluminações que pretendia um sistema de iluminação decorativa (baseada em LED) de dois conjuntos de 288 janelas, pertencendo cada conjunto a uma fachada diferente do edifício. Este sistema teria que prever a possibilidade de controlar a cor de cada janela individualmente, dando ao cliente a possibilidade de alterar o ambiente decorativo das fachadas do edifício. A utilização de comunicação sem fios foi justificada pela necessidade de evitar a quantidade enorme de cabos que seria necessário passar utilizando os sistemas comerciais convencionais e a impossibilidade de os esconder. Esta solução foi pensada para ser implementada num edifício com 14 Andares, facto que por si só inviabiliza a passajem de cabos. Para interligar todos os dispositivos de iluminação decorativa com um controlador portátil, e eliminar os problemas ligados à cablagem, foi utilizado o protocolo de comunicações sem fios ZigBee™. A escolha recaiu neste protocolo devido a factores como os seus baixos consumos, simplicidade do protocolo comparativamente com outras redes e o seu baixo custo. No desenvolvimento deste projecto foi utilizada a stack da Microchip©, versão gratuita, disponibilizada na internet e os seus transceivers de comunicação Zigbee™, MRF24j40MA. Para fazer a interface de comunicação com o utilizador, foi desenvolvida uma aplicação de Software para correr em computadores com ambiente Windows™. Esta aplicação foi desenvolvida em Visual Studio™ utilizando a linguagem C#. Foram efectuados alguns testes para se perceber a eficiência e robustez da comunicação ZigBee™ e apesar do número de dispositivos disponíveis para ensaios ser muito reduzido, foi possível verificar que, mesmo funcionando correctamente, o desempenho do sistema poderá ser melhorado, quer seja a nível da gestão das comunicações, quer a nível do software informático para controlo do ambiente decorativo das fachadas do edifício. O sistema, no actual estado de desenvolvimento, permite controlar a cor dos vários dispositivos da rede através do computador, com uma resolução de 24bits. A aplicação desenvolvida em Visual Studio™ permite controlar de forma simples e intuitiva para o utilizador, a cor do material iluminativo dos vários dispositivos da rede.
