Full textAbstract:
Tässä työssä toteutettiin I2C-väylällä ohjattu LED-ohjain. Lähtökohtana oli Digitaalitekniikka 2 kurssilla tehty harjoitustyö, joka sovitettiin FPGA-piirille. RTL-koodi vaati muutoksia vain siltä osin, että FPGA-alusta ja pohjana käytetty harjoitustyö käyttivät eri kellotaajuuksia. Jotta RTL-koodi saatiin toimimaan FGPA-alustalla, työssä perehdyttiin ensin FPGA-piirien konfiguroimiseen. Työn testaamista varten koottiin pienimuotoinen testausjärjestelmä, joka koostui FPGA- ja mikrokontrolleri-alustoista sekä logiikkatasonmuuntimesta. Mikrokontrollerille kirjoitettiin yksinkertainen arduino-koodi, jolla saatiin tehtyä testianimaatio LED-valojen testausta varten. Järjestelmän testaaminen aloitettiin visuaalisesti tarkastelemalla LED-valoja, jonka perusteella pystyttiin huomaamaan ilmeisimmät ongelmat. Lisäksi suoritettujen mittausten avulla pystyttiin rajaamaan ongelmien aiheuttajia ja varmentamaan väylän toiminta ja PWM-aaltomuodot. Korjaamalla virheet RTL-koodista ja lisäämällä logiikkatasonmuunnin, järjestelmä saatiin toimimaan ongelmitta<br>In this project, I2C bus controlled LED controller was implemented. The starting point was an assignment made on Digital Technology 2 course which was implemented on FPGA circuit for this project. The configuration of FPGA circuits was studied first in order to get RTL code to work on FPGA board. The RTL code was then modified and compiled for the FPGA. The small-scale test environment consisting of FPGA and MCU boards as well as logic level converter was made for testing the system. Simple Arduino code was written for MCU to get test animation for the LEDs. The testing of the system began by examining the LEDs visually. From this the most obvious problems were able to be noticed. In addition, causes of problems could be limited on the basis of made measurements. PWM-waveform and operation of the I2C bus were also verified by the measurements. The system was made to work without problems by correcting errors in RTL-code and adding logic level converter

Un appareil de mesure de la fluorescence, à faible coût et portable a été développé pour quantifier les concentrations d’Ochratoxine A (OTA) dans des échantillons réels. Le système est basé sur l’excitation par une UV-LED à 365 nm et un photo détecteur contrôlé par une interface dans LabVIEW. Aussi, une image capteur, CMOS, contrôlée par une interface conçue dans MATLAB. L’OTA est une molécule naturellement fluorescente. Après excitation par une UV-, l’image de la fluorescence émise est captée par une caméra et traitée en vue de la mesure de la concentration de l’OTA. Le système d’analyse a été basé sur les 3 composants rouge, vert et bleu (RGB, selon l'acronyme anglais). La gamme est linéaire entre de 2-40 µg/L. L’extraction de l’OTA est réalisée par des colonnes d'immuno affinité (IAC, selon l'acronymeanglais) et les colonnes à empreinte moléculaire (MIP, selon l'acronyme anglais) pour les échantillons de cacao, de la bière et du vin. Les résultats obtenus ont été validés par la méthode chromatographique (HPLC). L'appareil conçu est facile à utiliser, économique et portable. En outre, l'utilisation des nouvelles technologies a été inclus tels que l'emploi du smartphone pour détecter l'OTA et la création d'un APP. Des données d'image de fluorescence provenant de la caméra du smartphone et sont analysées par un ordinateur personnel et présentés dans les composantes RGB, où l'image est envoyée à l'ordinateur par WIFI et le téléphone intelligent est utilisé comme source d'énergie trop. Enfin, une APP pour le système Android a été créé pour capturer l'image et fournit les valeurs RGB. Enfin l'utilisation du traitement de l'image a été utilisée pour quantifier l'OTA dans les échantillons réels sans colonnes IAC ou MIP, employée pour extraire la mycotoxine. L’analyse a été réalisée par des techniques colorimétriques et d’analyse de la couleur<br>A portable and low cost fluorescence set-up to quantify the concentrations of Ochratoxin A(OTA) in real samples was developed. The detection through the device consist of anultraviolet light at 365 nm and an photo detector or a CMOS sensor controlled by anexecutable interface designed in LabVIEW or MATLAB. It has been reported that OTA is naturally fluorescent, so it allows the user to get a UV LED to excite the sample, get a value involtage when a photodetector is employed or a photograph of the OTA under excitationconditions, and process that image in order to predict the concentrations of the sample. Tocapture and process the image, in an automatically manner, the system was completely basedon the Red, Green and Blue (RGB) components. The linearity for OTA obtained in the rangeof concentrations corresponds to 2-40 µg/L. Immunoaffinity columns (IAC) and molecularimprinted polymer columns (MIP) were used with cocoa, beer and wine samples. Theobtained results were cross-validated using chromatographic method such as HPLC and theFluoroskan equipment. The developed setup is easy to use, economical and portable. Besides,the use of new tendencies was included such as employ the smartphone to detect OTA and thecreation of an APP. Fluorescence image data from the smartphone camera are analyzed by apersonal computer and presented in RGB components, where the image is sent to thecomputer by WIFI and the smartphone is used as a power source too. Finally, an APP forandroid system was created to capture the image and provides the RGB values. At the end, theuse of image processing to quantify the OTA in real samples without incorporated IAC or MIPcolumns to extract the mycotoxin from a complex solution, employing colorimetric techniquesand color analysis

Full textAbstract:
Syfte: Det finns idag stor förbättringspotential i arbetet med logistik och tidplanering på byggarbetsplatser. Ökad komplexitet har lett till ökade krav på detta. Dock har det visats i studier att byggbranschen är en av de minst digitaliserade branscherna som finns, trots alla verktyg som finns. Syftet med studien är att undersöka fördelar med att använda sig av BIM i arbetet med logistik- och tidplanering jämfört med de traditionella metoder som finns, och på så sätt se hur detta arbete kan effektiviseras. Metod: De valda undersökningsmetoderna för att besvara våra frågeställningar är fallstudie samt litteraturstudie. Dessa metoder lämpar sig bäst för den typen av studie som ska utföras. Empirin är insamlad via intervjuer med anställda på Gärahovs Bygg AB. Resultat: Studien har visat att respondenterna tror att kommunikationen mellan olika aktörer i projektet, till exempel entreprenörer och underentreprenörer, kan förbättras med hjälp av den BIM-baserade metoden. De tror också att det blir lättare att se att allt tas med i planeringen i projekteringsskedet. Nyttan med att använda BIM: • BIM-metoden kan ge en visuell fördel i kommunikationen mellan entreprenörer och underentreprenörer. • BIM-metoden kan ge en tydligare bild av hur arbetet ska fortskrida genom visuella simuleringar. • BIM-metoden kan göra det lättare att i tidplaneringsskedet se om alla tänkta aktiviteter finns med i planeringen. • BIM-metoden kan göra det lättare att göra avstämningar mot tidplanen under projektets gång. Begränsningar: Begränsningar är att endast göra en tidplan över en typlägenhet i ett projekt, och gör jämförelser endast med denna. Studien har endast gjorts tillsammans med ett företag. För att få högre trovärdighet i resultatet behövs fler företag att jämföra med. En simulering av en större modell hade kunnat ge en ännu klarare bild av vilka fördelar och nackdelar som finns med BIM-metoden.<br>Purpose: Today there is big room for improvements in the work with logistics and scheduling on construction sites. Increased complexity has led to increased demands on planning. However, studies have shown that construction is one of the least digitalised industries today, in spite of all tools available. The purpose of the study is to study the advantages of using BIM in the work with logistics and scheduling compared to the traditional methods available, and in that way see how this increase efficiency. Method: The research methods that was chosen to answer our issue are case studies and literature studies. Those methods are the best suited for these types of studies that are going to be done. Collection of data has been made through qualitative interviews with employees at Gärahovs Bygg AB. Findings: The study has shown that the interviewees believe that communication between different participants in the project can be improved using the BIM-based method. They also believe that it will be easier to see that everything is included in the planning phase. The benefit of using BIM: • The BIM method can provide a visual advantage in the communication between contractors and subcontractors. • The BIM method can give a clearer picture of how the work will proceed through visual simulations. • The BIM method can make it easier to see if all the planned activities are included in the planning phase. • The BIM method can make it easier to make reconciliations against the schedule during the project. Limitations: The study is limited to only make a production schedule over one typeapartment in a project, and to only make comparisons with this. The study has only been made together with one company. For a more reliable result, more companies would have to be included in the study. A simulation of a larger model could have given an even clearer picture of what advantages and disadvantages that comes with the BIM-based method.

Full textAbstract:
The introduction of smart grid technology has changed the way traditional power grid network function. It made the grid structure more dynamic by enhancing electrical usage management capability. Also, it has increased the scope to enhance communication infrastructure in a smart grid structure. The current smart grid solution is based on IEC 61850 architecture where the exchange of information between the electrical utilities is over the fast Ethernet LAN connection. This communication mechanism is fast, efficient but lacks scalability, flexibility and less susceptible to failure. Also, earlier technical paper from IEC 61850 standard was for communication within a substation. Wide Area Monitoring Protection and Control implementation which utilizes coherent real time synchrophasor information would play a vital role in realizing the utility physical status. IEC 61850-90-5, a new technical report from International Electrotechnical Commission provides the mechanism to transmit and receive the synchrophasor information using the advance IP protocol over a wireless communication infrastructure for WAMPAC application. IEC 61850-90-5 provide a way to exchange routable synchrophasor information over public IP network such as LTE, WiMax, WLAN, etc. Out of all the available wireless solution, LTE provides high flexibility, distance coverage, data rate with low latency and hence can play an important role in replacing the existing communication structure in a smart grid. The thesis work evaluates the performance and applicability of LTE for smart grid communication. An IEC 61850-90-5 communication model utilizing UDP/IP protocol to transmit and receive data over the LTE network was developed from the open source project. The modified model was used to benchmark the performance of LTE. Different communication metrics such as reliability, availability, latency, and throughput was evaluated to benchmark the performance of LTE for time critical smart grid application. The metrics were measured for different packet sizes and transmission rates combination. The result shares some interesting findings on the readiness of LTE for smart grid solution. It is concluded that cellular network can play an important role in realizing communication infrastructure in a smart grid application.

Many software companies face such problems as projects being behind schedule, exceeding the budget, customer dissatisfaction with product quality. Most of the problems arise due to immature software process of the company. The most popular process assessment models worldwide are ISO/IEC 15504 and CMMI. Companies seeking wider official recognition choose between these two models. Companies face the problem that different customers require process assessment according to different models. Therefore, it is important for companies to have an instrument that would transform company’s assessment results according to one process assessment model to another model without actual reassessment each time. The transitional process assessment model proposed in the dissertation allows the companies in the automotive, defence, space, medical, and other industries to have assessment results according to different process assessment models by performing only single process assessment. The presented method for TPAM development could be used developing transitional process assessment models in other domains. For example, service companies could implement a transitional model covering CMMI-SVC and ISO/IEC 15504-8 assessment models, and companies working in other areas could implement a transitional model covering Enterprise SPICE and FAA-iCMM assessment models.<br>Dauguma programinę įrangą kuriančių įmonių susiduria su problemomis: projektai vėluoja, viršijamas biudžetas, klientai nepatenkinti produktų kokybe. Daugelis problemų kyla dėl nebrandaus programų kūrimo proceso, pagal kurį įmonė įgyvendina projektus. Populiariausi pasaulyje programų kūrimo procesų vertinimo modeliai yra ISO/IEC 15504 ir CMMI. Įmonės, norėdamos būti oficialiai pripažintos platesnėje aplinkoje, renkasi vieną iš šių dviejų modelių. Įmonės susiduria su problema, kad skirtingi užsakovai reikalauja skirtingų procesų vertinimo modelių. Todėl įmonėms yra aktualu turėti instrumentą, kuris atvaizduotų jos vertinimo rezultatus iš vieno procesų vertinimo modelio į kitą, neatliekant kaskart realaus įmonės procesų vertinimo. Disertacijoje pateiktas tarpinis programų kūrimo procesų vertinimo modelis yra instrumentas įmonėms, siekiančioms kurti programų sistemas automobilių, krašto apsaugos, kosmoso, medicinos ir kitose pramonės šakose, gauti vertinimo rezultatus pagal įvairius procesų vertinimo modelius, atliekant vieną procesų vertinimą. Pagal pasiūlytą tarpinio programų kūrimo procesų vertinimo modelio kūrimo metodą galima kurti tarpinius modelius ir kitų sričių procesams vertinti. Pavyzdžiui, galima konstruoti tarpinį modelį paslaugas teikiančioms organizacijoms, apimantį CMMI-SVC ir ISO/IEC 15504-8 vertinimo modelius, arba tarpinį modelį bet kokia veikla užsiimančioms organizacijoms, apimantį Enterprise SPICE ir FAA-iCMM vertinimo modelius.

Dauguma programinę įrangą kuriančių įmonių susiduria su problemomis: projektai vėluoja, viršijamas biudžetas, klientai nepatenkinti produktų kokybe. Daugelis problemų kyla dėl nebrandaus programų kūrimo proceso, pagal kurį įmonė įgyvendina projektus. Populiariausi pasaulyje programų kūrimo procesų vertinimo modeliai yra ISO/IEC 15504 ir CMMI. Įmonės, norėdamos būti oficialiai pripažintos platesnėje aplinkoje, renkasi vieną iš šių dviejų modelių. Įmonės susiduria su problema, kad skirtingi užsakovai reikalauja skirtingų procesų vertinimo modelių. Todėl įmonėms yra aktualu turėti instrumentą, kuris atvaizduotų jos vertinimo rezultatus iš vieno procesų vertinimo modelio į kitą, neatliekant kaskart realaus įmonės procesų vertinimo.

Most of the problems arise due to immature software process of the company. The most popular process assessment models worldwide are ISO/IEC 15504 and CMMI. Companies seeking wider official recognition choose between these two models. Companies face the problem that different customers require process assessment according to different models. Therefore, it is important for companies to have an instrument that would transform company’s assessment results according to one process assessment model to another model without actual reassessment each time. The transitional process assessment model proposed in the dissertation allows the companies in the automotive, defence, space, medical, and other industries to have assessment results according to different process assessment models by performing only single process assessment. The presented method for TPAM development could be used developing transitional process assessment models in other domains. For example, service companies could implement a transitional model covering CMMI-SVC and ISO/IEC 15504-8 assessment models, and companies working in other areas could implement a transitional model covering Enterprise SPICE and FAA-iCMM assessment models.

Informacinė visuomenė – tai atvira naujovėms, išsilavinusi ir trokštanti tobulėti, nuolat besimokanti visuomenė. Informacinių technologijų plitimas tampa neatsiejama dalimi ugdymo procese. Pastebime, kad mokyklose sparčiai daugėja IKT priemonių, todėl galime teigti, kad šis pokytis atveria plačias ugdymo proceso galimybes. IKT diegimo Lietuvos švietime strategija siekia integruoti informacinės kultūros ugdymą į visą bendrojo lavinimo mokyklos ugdymo procesą, skatinti inovatyvių mokymosi formų ir metodų diegimą. Pradinių klasių mokiniai prieš ateidami į mokyklą jau yra įgyję elementarių techninių įgūdžių.Todėl IKT integravimas pradinėse klasėse taip pat yra neišvengiamas. Mūsų temai aktualu IKT naudojimas gimtosios kalbos pamokose pradinėse klasėse. IKT integravimas pamokose padeda mokiniams įsisavinti lietuvių kalbos žinias, formuoja techninius įgūdžius ir gerina mokymosi rezultatus. Tai mus paskatino atlikti tyrimą.<br>Modern society becoming informational or knowledge seeking society, knowledge gets more and more important part in our lives. Informational society – it’s society that is open for innovation, educated and eager to improve, always learning society. Spread of informational technologies is becoming more important part in education process. We can notice that schools are getting more and more ICT devices, so we can state that these changes are opening wide opportunities for educational progress. The strategy of installing ICT in Lithuanians education is to combine informational culture progress and general education progress, that should motivate innovative form of learning. Elementary school student before coming to school usually already has basic set of technical skills, so using of ICT in elementary school is inevitable. It’s relevant to our subject that ICT should be used in birth language classes in elementary school. Using ICT in classes helps students to get basic knowledge of Lithuanian language, creates technical skills and upgrades results of learning. That led us to this research.

In the epoch of the modern global changes, a new form of society is being formed. The individual knowledge of a person is becoming a still more important basis of the quality of economic and social life. The reform of education in Lithuania is taking place for more than a decade, and within this period many essential changes occurred. Lithuania is oriented towards the aims of the European Union, it seeks to become the competitive member of the European Union, is open to various novelties and aims to strengthen its education system, so that it would educate the full-fledged members of modern society.
The present-day changes also conditioned the emergence of social problems, which had a strong effect on the whole social life, including school life. The necessity came forth to take all necessary measures for the improvement of social situation. Social pedagogues, whose position has been introduced in the educational establishments from 2001, may help to solve these problems.
One of the priority trends in the development of modern society is the rapid implementation of communication technologies in all the fields of activities. In implementing information and communication technologies at school it is also necessary to integrate in this process the functions performed by a social pedagogue.

Find full textAbstract:
The research developed in this thesis is focused on the development of a validation method for BIM-based digital models for the disciplines of the Construction sector, in order to satisfy the interoperability requirements established by the Italian Codes and Regulations, to allow archiving and to make digital models suitable for future interventions.
The Validation method involves a deep analysis, using specialized software, of the Architectural, Structural and Systems Design, embedded into BIM digital models as it can be expressed through Levels of Detail (LoD) in the open and neutral Industry Foundation Classes (IFC) format. A reliability scale to evaluate how information can be properly organized in IFC models was proposed in this thesis. If the percentage of reliability obtained from the analysis is less than an imposed threshold, the model is considered unreliable and it has to be fixed by designers. Otherwise, following the Employer Information Requirements as it is requested by Italian laws, the model is explored in more detail to check if all project requirements are met. If this final check is successful, the model is valid and usable for the purposes of the design process.
The validation method proposed was tested on a real case study, the “Nuova sede del commissariato della Polizia di Stato in Cesena”, actually prepared for real public procurement. The study was provided by Provveditorato Interregionale per le Opere Pubbliche Lombardia – Emilia-Romagna.
The results of the analysis proved how most of the errors found in models were due to bad management of the IFC format. In the case study, the requirements of the Employer Information Requirements were all present, allowing to follow all the steps proposed in the validation method developed. In conclusion, the study presented in this thesis contributes to bring novel criteria in the validation of BIM models, which can be extended to all needs expressed by public and private construction sector.

Konstruktyvistinę mokymosi paradigmą, pagrindinius šiuolaikinius didaktinius matematikos mokymo principus – suprantamumą, sąmoningą ir aktyvų žinių perėmimą, vaizdumą, mokymo diferencijavimą, individualizavimą ir kt. – gali įgyvendinti tik atitinkamos kompetencijos matematikos mokytojai. Šalies pedagogų kompiuterinio raštingumo standarto, numatančio mokytojų gebėjimus naudoti IKT ugdymo procese, vienas iš reikalavimų yra „Žinoti pagrindinių ugdymui naudojamų kompiuterinių programų tipus, gebėti analizuoti jų privalumus ir trūkumus. Mokėti pritaikyti svarbiausias bendrosios paskirties ir mokomąsias kompiuterines programas ugdymo procese“. Šio bendro reikalavimo taikymas matematikos mokymui – tai ne tik sudėtingų matematikai taikytinų technologijų žinojimo ir įvaldymo, bet ir gebėjimų tinkamai taikyti jas matematikos mokyme reikalavimas.

[toliau žr. visą tekstą]<br>This master‘s thesis seeks to provide a theoretical framework for better understanding current Information & communication technology (ICT) enabled structural changes in services’ production & trade & perform an analysis using the developed framework.
In the first part, services’ definitions & characteristics are examined by performing a critical analysis of existing theories with the purpose to identify a common denominator to enable identification of the internal determinants of the changes. It is concluded that services comprise a very wide range of economic goods which are extremely difficult (if not impossible) to generalize. The conceptualization of services is therefore far from complete.
Further study showed that there exists a fundamental division within the services category, the defining feature of which is possibility of separation of services’ production & consumption. A theoretical framework for analysis of services’ production & consumption & production processes’ separability is produced by identifying 4 dimensions of separability & developing their matrix. Due to another important feature of services, their inherent immateriality, separability is greatly enhanced for some services or even enabled altogether for some others by Information & communication technology revolution. ICT further contributed to services’ separabillity by making it possible to fragment services’ production into constituent components some of which can be separated.

Full textAbstract:
碩士<br>國立臺灣大學<br>企業管理碩士專班<br>99<br>Intellectual property management and the built-up of patent portfolio is not a new concept for Taiwanese ODM/OEM companies. Nor is this a new concept for those ODM/OEM companies who are engaged in the LCD TV manufacturing business. With that said, as AmTRAN began its relationship with Vizio, a new brand player in the United States, and as Vizio’s sales volume increases, it became the prime target for attacks on the intellectual property front of the LCD TV industry in the U.S.
Neither AmTRAN nor Vizio had a very strong patent portfolio, and neither company placed too much emphasis on the management of intellectual property as both companies were busy developing and marketing the products. This research paper first analyzes the overall intellectual property environment for the LCD TV industry in the United States with the Teece model, and then examines the internal intellectual property environment of both AmTRAN and Vizio with the SWOT analysis. Based on Pitkethly ad Reitzig’s intellectual property management and organizational model, AmTRAN and Vizio need to have better external and internal IP management. Both companies should also adopt Afuah’s team-up strategy as the initial framework as they try to improve their intellectual property management. Afuah’s team-up strategy can also be used by the different Taiwanese OEM/ODM to create a patent pool

碩士<br>國立交通大學<br>管理學院碩士在職專班財務金融組<br>99<br>Taiwan has been a significant base in semi-conductor industry of the world. Taiwan companies have played an important role in Wafer Foundry, IC design, or IC assembly and testing. For instance, TSMC and UMC are the first and second largest wafer foundries in the world, while some IC-design companies rank in the top 10. As to Assembly and Testing, ASE and Spil had been in the second and third place in the SAT. However, since 2003, ASE has replaced Amkor to be the largest SAT company in the world due to its successful activities of M&A and Strategic alliance. ASE and Amkor have actively employed external growth strategies to strive for the champion position in SAT industry. As to Spil, Spil has always been in the third place in SAT industry due to its fewer and conservative activities of external growth. Accordingly, I conduct case study method on these three companies and take a deep analysis of the impact on the company growth brought by each event of M&A and strategic alliance in the priod from 1999 to 2008. Due to limited examples during ten years of my research, I did not perform regression analysis and Hypothesis test to understand the relationship between M&A, Strategic alliance with company growth. However, after case study of these three companies. I did found that M&A and strategic alliance did contribute positive company growth in the next year. Moreover, after comparison of the changes in the SAT ranking of these three companies, I noticed that with appropriate and successful M&A and Strategic alliance strategies as well as continuous capital expenditure and R&D activities, ASE has replaced Amkor to be the champion in the SAT industry.

We live in an era where the consumption of energy rises to an almost immeasurable level, jeopardizing the balance of systems when a power failure in the electrical grid occurs. This brought the necessity of making it safer and intelligent, hence emerging the concept of Smart Grid.
The IEC 61850 standard was initially designed to operate within substations, yet other potential developments glimpsed to operate not only within substations but also to the outside of them. Based on several communications protocols, including MMS, GOOSE and SV, the IEC 61850 provides the possibility of real-time data exchange, leading to cost savings, increased security and interoperability between different vendors’ devices.
Addressing this issue, together with EFACEC and the Institute of Telecommunications of Aveiro, a key question emerged: What are the requirements for the communication between devices in different substations?
This MSc dissertation aims to answer this question, as well as to analyse other possible technologies that are suitable at the time of its implementation. With this analysis, a specific technology stands out, the 4G-LTE. A study was conducted recurring to temporal diagrams of the messages, performing with both approaches as described in the standard. Either using the IP or VPN approach, different technologies such as ADSL, Optical Fibre, and the previously referred 4G-LTE were tested. Thereafter, the results of the study are analysed, obtaining this way the conclusions for each one of the approaches, as well for each of the different technologies studied.
Last but not least, it is analysed which of the approaches will be more beneficial in the long-term, as well as the necessary future work that must be developed in the different areas of the presented standard.<br>Vivemos numa era em que o consumo de energia cresce a um nível quase imensurável, colocando em causa o equilíbrio de um sistema aquando a ocorrência de uma falha na rede elétrica. Isto trouxe a necessidade de a tornar numa rede mais segura e inteligente, surgindo então o conceito de Smart Grid.
O standard IEC 61850 foi inicialmente concebido para operar dentro das subestações, contudo vislumbraram-se outras potencialidades para o aplicar não só dentro, mas também para fora das mesmas. Assente em vários protocolos de comunicação, entre os quais MMS, GOOSE e SV, o IEC 61850 oferece a possibilidade de troca de dados em tempo real, levando a uma redução de custos, um aumento da segurança bem como a interoperabilidade entre os equipamentos dos diferentes vendedores.
Abordando este tema em conjunto com a EFACEC e o Instituto de Telecomunicações de Aveiro, houve uma questão se levantou: Quais são as condições requeridas para a comunicação entre os equipamentos das diferentes subestações?
Esta dissertação de mestrado visa dar resposta a esta questão, assim como analisar outras possíveis tecnologias a utilizar no momento da sua implementação. Realizada essa análise, houve uma tecnologia que se evidenciou, o 4G-LTE. Foi elaborado um estudo com recurso a diagramas temporais de mensagens, utilizando as duas abordagens descritas no standard. Quer utilizando a abordagem por IP quer utilizando a abordagem por VPN, foram testados em ambos os cenários diferentes tecnologias como a ADSL, Fibra Ótica, bem como o já referido, 4G-LTE. De seguida, são analisados os resultados do estudo, obtendo as devidas conclusões para cada uma das abordagens bem como para cada uma das diferentes tecnologias.
Por fim, é analisada qual das abordagens será mais proveitosa a longo prazo, assim como qual o trabalho futuro que deverá ser desenvolvido no que diz respeito às diferentes áreas do standard apresentado.<br>Mestrado em Engenharia Eletrónica e Telecomunicações

Full textAbstract:
碩士<br>淡江大學<br>大眾傳播學系<br>88<br>.The IMC is one of the most interested subjects for the circles of academy and business in the communication at home and abroad in the nineties. Both circles consider that in the process of the competition in the market and the assimilation of products, the integrated messages from the receivers can help them to have market orientation in hand and to coincide with the trend of an epoch. The business circle of the communication in Taiwan is also sensitive to this trend, and tries to join this concept into the operation models of marketing communication in succession. This research first focuses on tracing and probing into the concept of the IMC, and then studies the service industry of the mobile telecommunication systems in Taiwan, and, moreover, uses the Fareastone Telecommunications Co. Ltd. as a case study.
This research is to study how the IMC is recognized by and applied practically to the service industry of the mobile telecommunication systems in Taiwan. Besides, in view of some domestic and foreign studies about the concept of the IMC, this research deeply explores how the case enterprise builds and uses its database, how it undertakes the analysis of the consumers and the stakeholders, how it develops the best strategies of marketing communication for the consumers and the stakeholders, how it integrates and makes use of the tactics and tools of marketing communication, how it conveys messages to the outward in the tune of uniformity for coinciding with the IMC, and how the enterprise adjusts and adapts correspondingly its operation and structure. In addition, this research expects to set up a regulation model of the IMC that can be used in practice, and this model will be provided as reference for the business circle when the IMC is carried on.
This research chooses the service industry of the mobile telecommunication systems as the case study mainly because of the characteristics of this kind of industry and its energetic performance in the past two years here in Taiwan. As for the standard of choosing a particular case, this research considers that an enterprise, which is familiar with and highly approves the concept of the IMC, which has excellent performance in actively making strategic policies in marketing communication, and which is willing to provide relevant information in coordination with this research, will take the priority over the others. This research is an elementary study of the IMC and proceeding with a case study. The case study is basically by means of explicit and thorough interviews with both the internal personnel of the enterprise and the scholars in the circle of marketing communication, and then tries to collect and analyze the primary and secondary materials from them.
This research shows that the database is the central administration of the IMC. An enterprise should build up its database and statistically analyze the database regularly to get grip of the trend in the market and to be able to respond to the trend immediately. In addition to emphasizing the benefits to the consumers, the IMC should also analyze the stakeholders, and put the analysis into the IMC regulation model. When an enterprise is carrying out the IMC, it ought to establish an interdepartmental group for the IMC, which is able to communicate individually with every other department and is supported by all of the departments in the enterprise. Furthermore, when the enterprise is proceeding with the IMC, it should integrally make use of every possible tactics and tool of marketing communication, and deliver the messages to the outward in unanimity. This research also finds the operation ideas and mission should be regarded as the most fundamental principle when an enterprise is undertaking the IMC. Only when the core value and the position of an enterprise are definitely located, the enterprise can hand over the messages of communication identically.
This research thinks that the ultimate goal of the IMC is to set up the brand equity and to maintain a long-run relationship with the customers. Nowadays, owing to the fierce competition among the service industry of the mobile telecommunication systems and the characteristics of the industry, enterprises of this industrial circle believe that founding the brand equity will be the key to the final victory.
