Implementing gateway monitoring service for infrastructure sensor networks

Wireless sensor networks and its applications have been widely researched and implemented in both commercial and non commercial areas. The usage of wireless sensor network has developed its market from military usage to daily use of human livings. Wireless sensor network applications from monitoring prospect are used in home monitoring, farm fields and habitant monitoring to buildings structural monitoring. As the usage boundaries of wireless sensor networks and its applications are emerging there are definite ongoing research, such as lifetime for wireless sensor network, security of sensor nodes and expanding the applications with modern day scenarios of applications as web services. The main focus in this thesis work is to study and implement monitoring application for infrastructure based sensor network and expand its usability as web service to facilitate mobile clients. The developed application is implemented for wireless sensor nodes information collection and monitoring purpose enabling home or office environment remote monitoring for a user.

Consistency of UML based designs using ontology reasoners

Software plays an important role in our society and economy. Software development is an intricate process, and it comprises many different tasks: gathering requirements, designing new solutions that fulfill these requirements, as well as implementing these designs using a programming language into a working system. As a consequence, the development of high quality software is a core problem in software engineering. This thesis focuses on the validation of software designs. The issue of the analysis of designs is of great importance, since errors originating from designs may appear in the final system. It is considered economical to rectify the problems as early in the software development process as possible. Practitioners often create and visualize designs using modeling languages, one of the more popular being the Uni ed Modeling Language (UML). The analysis of the designs can be done manually, but in case of large systems, the need of mechanisms that automatically analyze these designs arises. In this thesis, we propose an automatic approach to analyze UML based designs using logic reasoners. This approach firstly proposes the translations of the UML based designs into a language understandable by reasoners in the form of logic facts, and secondly shows how to use the logic reasoners to infer the logical consequences of these logic facts. We have implemented the proposed translations in the form of a tool that can be used with any standard compliant UML modeling tool. Moreover, we authenticate the proposed approach by automatically validating hundreds of UML based designs that consist of thousands of model elements available in an online model repository. The proposed approach is limited in scope, but is fully automatic and does not require any expertise of logic languages from the user. We exemplify the proposed approach with two applications, which include the validation of domain specific languages and the validation of web service interfaces.

Electrical Safety of Island Operated Low Voltage DC Network

Today, renewable energy technologies and modern power electronics have made it feasible to implement low voltage direct current (LVDC) microgrids (MGs) ca-pable to island operation. Such LVDC networks are particularly useful in remote areas. However, there are still pending issues in island operated LVDC MGs like electrical safety and controlled operation, which should be addressed before wide-scale implementation. This thesis is focused on the overall protection of an island operated LVDC network concept, including protection against electrical shocks, mains equipment protection and protection of photovoltaic (PV) power sources and battery energy storage systems (BESSs). The topic is approached through ex-amination of the safety hazards and the appropriate methods to protect against them, comprising considerations for earthing system selection and realisation of the protection system.

Virtuaalisten oppimisympäristöjen ominaisuusvertailu ja suunnittelu

Tietotekniikan ja tietoliikenneyhteyksien nopea kehittyminen on avannut opetusteknologialle paljon uusia mahdollisuuksia. Nopeat tietoliikenneyhteydet ja mobiililaitteet ovat yhä useamman oppilaan ja opettajan saatavilla, mikä on mahdollistanut uudenlaisten, teknologiaa hyödyntävien opetusmuotojen suosion runsaan kasvun. Tällaisia ovat esimerkiksi massiiviset avoimet verkkokurssit, sulautettu oppiminen ja käänteinen opetus. Työelämässä olevien informaatioteknologian alan ammattilaisten tulee jatkuvasti kehittää osaamistaan, kun uusia ja korvaavia teknologioita tulee käyttöön nopeassa tahdissa. Todistuksena tiedoista ja taidoista ovat eritasoiset, kansainvälisesti hyväksytyt sertifikaatit. Tämän tutkielman tavoitteena on suunnitella ja toteuttaa virtuaalinen oppimisympäristö, jossa teorian opiskelu yhdistetään käytännön harjoitteluun. Oppimisympäristö on tarkoitettu erityisesti informaatioteknologia-alan sertifiointikokeisiin harjoittelua varten. Erilaisten virtuaalisten oppimisympäristöjen hyödyntämistä on tutkittu jonkin verran, mutta tutkimus on painottunut pääosin perusasteen opintoihin. Virtuaaliopiskelun hyödyntämisestä IT-alan sertifiontijärjestelmässä on olemassa hyvin vähän tutkimustietoa. Uuden oppimisympäristön suunnittelun perustana käytetään tässä tutkimuksessa toteutettua, suosittujen virtuaalisten oppimisympäristöjen vertailua. Vertailuun valikoituivat opetusvideosivusto Khan Academy, Cisco Systems Oy:n Networking Academy, massiivisia avoimia verkkokursseja tarjoava Coursera sekä yhteistyötä tukeva opetusjärjestelmä ViLLE. Vertailun pohjalta todetaan uuden oppimisympäristön soveltuvan erinomaisesti IT-alan sertifiontikokeiden opiskeluun erityisesti tapauksissa, joissa käytännön harjoituksia tekemällä voidaan saavuttaa parempi oppimistulos. Uusi oppimisympäristö on ominaisuuksiltaan ainutlaatuinen eikä vastaavaa järjestelmää ole toistaiseksi kehitetty. Keskeisimpinä ominaisuuksina mainitaan esimerkiksi automaattinen arviointi sekä harjoitteluympäristön palauttaminen alkutilaan täysin automaattisesti. Lopuksi kuitenkin todetaan, että kehitetyn ratkaisun hyödyllisyyden arvioimiseksi vaaditaan nykyistä merkittävästi suurempi käyttäjämäärä sekä kehittyneemmät menetelmät käyttäjädatan analysointiin.

Incorporating Sustainability in Global Sourcing Process, Industry Focus- Apparel / Textile

This is a Master’s thesis research, which mainly aims at identifying the sustainability issues in sourcing process and to identify the core competencies in sourcing process through triple bottom line adaptation. The focus of this thesis is on apparel industry’s sourcing process. The purpose of this thesis is to examine global apparel industry’s reality in their sourcing process and how buyers-suppliers are cooperating with their sourcing process to incorporate sustainability. Other goal of this research paper is to provide recommendation for sustainable sourcing process for companies and how the stakeholders can be benefitted by sustainable sourcing. The literature review part of this paper has presented the research gaps from the earlier researches along with the key concepts, academic purposes and key definitions. Theoretical framework chapter has focused on global sourcing strategies and firm’s competencies and sustainable strategies. From the theoretical framework, author has presented essential theory which establishes the link between research questions and proposed hypotheses. Main results and findings have been presented in empirical findings and in data analysis chapter. This study is an exploratory research followed by deductive method and primary data has been used to evaluate the current situation of apparel industry; which will assist to build the recommendation model. Primary data has been collected through online questionnaires and secondary data has used to cover the literature and theoretical parts. Therefore, the potential outcome of this paper will display the importance of sustainable sourcing from academic point of view and also from the business perspective. As a final point, this paper has followed the research objectives and has generated some new directions for further studies.
