Context-based services for mobile devices

The subject of this master’s thesis was developing a context-based reminder service for mobile devices. Possible sources of context were identified and analyzed. One such source is geographical location obtained via a GPS receiver. These receivers consume a lot of power and techniques and algorithms for reducing power consumptions were proposed and analyzed. The service was implemented as an application on a series 60 mobile phone. The application requirements, user interface and architecture are presented. The end-user experiences are discussed and possible future development and research areas are presented.

Java Mobile Media API porting in Symbian Operating System

Työssä tutkitaan, kuinka Symbian käyttöjärjestelmälle voidaan tehdä siirrettäviä ohjelmia. Työssä käydään läpi menetelmiä, jotka helpottavat ohjelmistojen siirrettävyyttä uudelle alustalle. Uuteen älypuhelimeen voi tulla monia uusia komponentteja. Laite voi muuttua piiritasolla, käyttöjärjestelmästä voi tulla uusi versio sekä siirrettävästä ohjelmasta voi tulla uusi versio. Kaikki nämä vaikuttavat ohjelman siirrettävyyteen. Työssä tehtiin Java-rajapinnan siirto uudelle alustalle. Prosessin aikana löydettiin tärkeitä tekijöitä, jotka vaikuttavat ohjelmiston siirrettävyyteen. Siirrettävyys sinänsä pitäisi ottaa huomioon ohjelmistoprosessin jokaisessa vaiheessa. Älypuhelimista tulee jatkuvasti uusia versioita. Tämä tekee ohjelmien siirrettävyydestä hyvin tärkeän tekijän ohjelmistojen suunnittelussa. Hyvin suunniteltu ohjelma on helpompi ylläpitää, päivättää ja siirtää myöhemmin.

BioSWR - Semantic Web services Registry for Bioinformatics

Article About the Authors Metrics Comments Related Content Abstract Introduction Functionality Implementation Discussion Acknowledgments Author Contributions References Reader Comments (0) Figures Abstract Despite of the variety of available Web services registries specially aimed at Life Sciences, their scope is usually restricted to a limited set of well-defined types of services. While dedicated registries are generally tied to a particular format, general-purpose ones are more adherent to standards and usually rely on Web Service Definition Language (WSDL). Although WSDL is quite flexible to support common Web services types, its lack of semantic expressiveness led to various initiatives to describe Web services via ontology languages. Nevertheless, WSDL 2.0 descriptions gained a standard representation based on Web Ontology Language (OWL). BioSWR is a novel Web services registry that provides standard Resource Description Framework (RDF) based Web services descriptions along with the traditional WSDL based ones. The registry provides Web-based interface for Web services registration, querying and annotation, and is also accessible programmatically via Representational State Transfer (REST) API or using a SPARQL Protocol and RDF Query Language. BioSWR server is located at http://inb.bsc.es/BioSWR/and its code is available at https://sourceforge.net/projects/bioswr/​under the LGPL license.

Developing customer need based services in personal security service industry

The purpose of this thesis is to examine how services can be developed and how the voice of the customer can be incorporated to the strategic planning of services. Furthermore, the objective is to investigate the methods of customer need analysis and service bundling. The data is collected from secondary and primary sources by reviewing the existing academic literature and by conducting in-depth interviews and surveys. The main findings of this research indicate that the service development in personal security service industry should be conducted through a formalized process and the process should begin with setting the strategic objectives. Moreover, the voice of the customer should be incorporated into all stages of the development process, especially into the front-end of the process. Furthermore, the information on customer needs should be gathered in a manner tailored for the purposes of service development.

A cyber security architecture for military networks using a cognitive network approach

Cyber security is one of the main topics that are discussed around the world today. The threat is real, and it is unlikely to diminish. People, business, governments, and even armed forces are networked in a way or another. Thus, the cyber threat is also facing military networking. On the other hand, the concept of Network Centric Warfare sets high requirements for military tactical data communications and security. A challenging networking environment and cyber threats force us to consider new approaches to build security on the military communication systems. The purpose of this thesis is to develop a cyber security architecture for military networks, and to evaluate the designed architecture. The architecture is described as a technical functionality. As a new approach, the thesis introduces Cognitive Networks (CN) which are a theoretical concept to build more intelligent, dynamic and even secure communication networks. The cognitive networks are capable of observe the networking environment, make decisions for optimal performance and adapt its system parameter according to the decisions. As a result, the thesis presents a five-layer cyber security architecture that consists of security elements controlled by a cognitive process. The proposed architecture includes the infrastructure, services and application layers that are managed and controlled by the cognitive and management layers. The architecture defines the tasks of the security elements at a functional level without introducing any new protocols or algorithms. For evaluating two separated method were used. The first method is based on the SABSA framework that uses a layered approach to analyze overall security of an organization. The second method was a scenario based method in which a risk severity level is calculated. The evaluation results show that the proposed architecture fulfills the security requirements at least at a high level. However, the evaluation of the proposed architecture proved to be very challenging. Thus, the evaluation results must be considered very critically. The thesis proves the cognitive networks are a promising approach, and they provide lots of benefits when designing a cyber security architecture for the tactical military networks. However, many implementation problems exist, and several details must be considered and studied during the future work.

Adopting the Vaadin Java framework to rebuild VTT’s Web Interfaces and Database Applications

With the growth in new technologies, using online tools have become an everyday lifestyle. It has a greater impact on researchers as the data obtained from various experiments needs to be analyzed and knowledge of programming has become mandatory even for pure biologists. Hence, VTT came up with a new tool, R Executables (REX) which is a web application designed to provide a graphical interface for biological data functions like Image analysis, Gene expression data analysis, plotting, disease and control studies etc., which employs R functions to provide results. REX provides a user interactive application for the biologists to directly enter the values and run the required analysis with a single click. The program processes the given data in the background and prints results rapidly. Due to growth of data and load on server, the interface has gained problems concerning time consumption, poor GUI, data storage issues, security, minimal user interactive experience and crashes with large amount of data. This thesis handles the methods by which these problems were resolved and made REX a better application for the future. The old REX was developed using Python Django and now, a new programming language, Vaadin has been implemented. Vaadin is a Java framework for developing web applications and the programming language is extremely similar to Java with new rich components. Vaadin provides better security, better speed, good and interactive interface. In this thesis, subset functionalities of REX was selected which includes IST bulk plotting and image segmentation and implemented those using Vaadin. A code of 662 lines was programmed by me which included Vaadin as the front-end handler while R language was used for back-end data retrieval, computing and plotting. The application is optimized to allow further functionalities to be migrated with ease from old REX. Future development is focused on including Hight throughput screening functions along with gene expression database handling

The infared optical properties of Sr2RuO4 and SmTiO3 including an object-oriented resistivity interface /

The perovskite crystal structure is host to many different materials from insulating to superconducting providing a diverse range of intrinsic character and complexity. A better fundamental description of these materials in terms of their electronic, optical and magnetic properties undoubtedly precedes an effective realization of their application potential. SmTiOa, a distorted perovskite has a strongly localized electronic structure and undergoes an antiferromagnetic transition at 50 K in its nominally stoichiometric form. Sr2Ru04 is a layered perovskite superconductor (ie. Tc % 1 K) bearing the same structure as the high-tem|>erature superconductor La2_xSrrCu04. Polarized reflectance measurements were carried out on both of these materials revealing several interesting features in the far-infrared range of the spectrum. In the case of SmTiOa, although insulating, evidence indicates the presence of a finite background optical conductivity. As the temperature is lowered through the ordering temperature a resonance feature appears to narrow and strengthen near 120 cm~^ A nearby phonon mode appears to also couple to this magnetic transition as revealed by a growing asymmetry in the optica] conductivity. Experiments on a doped sample with a greater itinerant character and lower Neel temperature = 40 K also indicate the presence of this strongly temperature dependent mode even at twice the ordering temperature. Although the mode appears to be sensitive to the magnetic transition it is unclear whether a magnon assignment is appropriate. At very least, evidence suggests an interesting interaction between magnetic and electronic excitations. Although Sr2Ru04 is highly anisotropic it is metallic in three-dimensions at low temperatures and reveals its coherent transport in an inter-plane Drude-like component to the highest temperatures measured (ie. 90 K). An extended Drude analysis is used to probe the frequency dependent scattering character revealing a peak in both the mass enhancement and scattering rate near 80 cm~* and 100 cm~* respectively. All of these experimental observations appear relatively consistent with a Fermi-liquid picture of charge transport. To supplement the optical measurements a resistivity station was set up with an event driven object oriented user interface. The program controls a Keithley Current Source, HP Nano-Voltmeter and Switching Unit as well as a LakeShore Temperature Controller in order to obtain a plot of the Resistivity as a function of temperature. The system allows for resistivity measurements ranging from 4 K to 290 K using an external probe or between 0.4 K to 295 K using a Helium - 3 Cryostat. Several materials of known resistivity have confirmed the system to be robust and capable of measuring metallic samples distinguishing features of several fiQ-cm.

Study of the application of the high performance liquid chromatography-particle beam interface-mass spectrometry technique on some pesiticides and the reduction phenomena in the system

This work includes two major parts. The first part of the work concentrated on the studies of the application of the highperfonnance liquid chromatography-particle beam interface-mass spectrometry system of some pesticides. Factors that have effects on the detection sensitivity were studied. The linearity ranges and detection limits of ten pesticides are also given in this work. The second part of the work concentrated on the studies of the reduction phenomena of nitro compounds in the HPLC-PB-MS system. Direct probe mass spectrometry and gas chromatography-mass spectrometry techniques were also used in the work. Factors that have effects on the reduction of the nitro compounds were studied, and the possible explanation is proposed. The final part of this work included the studies of reduction behavior of some other compounds in the HPLC-PB-MS system, included in them are: quinones, sulfoxides, and sulfones.

Being a bereaved parent : early bereavement experiences and perspectives on paediatric palliative care and bereavement services

La mort d'un enfant est considérée comme l'une des expériences les plus difficiles à laquelle une personne puisse faire face. Les cliniciens, les hôpitaux et plusieurs organismes ont pour objectif d’aider les parents endeuillés, mais leurs efforts sont compliqués par un manque de recherche dans le domaine du deuil parental. Cette thèse est composée de trois articles, soit deux revues de littérature et une étude empirique, qui tentent de combler cette lacune et d’informer les services en soins palliatifs pédiatriques et les services de soutien au deuil en particulier. Le premier article porte sur les besoins des patients recevant des soins palliatifs pédiatriques et de leurs familles. Par le biais d’un méta-résumé de la recherche descriptive et qualitative récente, 10 domaines de besoins ont été identifiés qui correspondent aux lignes directrices actuelles en soins palliatifs pédiatriques et de fin de vie. Ces besoins sont présentés de manière à être facilement applicables à la pratique. Cependant, les résultats mettent aussi en évidence plusieurs aspects des soins identifiés comme déficitaires ou problématiques qui mériteraient une attention particulière dans le cadre de politiques futures. Dans le deuxième article, l'objectif était de résumer une vaste littérature d'une manière utile aux cliniciens. À cette fin, une synthèse narrative a permis d’intégrer la recherche quantitative et qualitative dans le domaine du deuil parental. Les résultats mettent en évidence les éléments susceptibles de favoriser l’adaptation des parents au deuil, éléments qui suggèrent par le fait même des avenues possibles de soutien et d'intervention. Cette synthèse a cependant cerné dans la littérature certaines failles méthodologiques qui rendent l'applicabilité clinique des résultats difficile. L'objectif du troisième article était d'informer les services de suivi et de soutien au deuil auprès des parents en se renseignant directement auprès de parents endeuillés. À cette fin, 21 parents (dont 8 couples) et 7 membres du personnel impliqués dans des activités de suivi de deuil de 2 hôpitaux pédiatriques ont été interrogés dans le cadre d’une description interprétative, et l'application clinique des résultats a été vérifiée par le biais de réunions avec des collaborateurs de recherche et les décideurs des centres hospitaliers. Les résultats décrivent comment les parents ont fait face à leur détresse dans la phase précoce de leur deuil, ainsi que leurs points de vue sur la façon dont les divers services de suivi de deuil ont été aidants. Les résultats suggèrent que les parents gèrent leurs sentiments intenses de douleur par une alternance de stratégies axées soit sur leur deuil ou sur leur quotidien et que dans plusieurs cas leurs relations avec autrui les ont aidé. Cette étude a également permis d'élucider la façon dont divers services de soutien aide les parents à aborder leur deuil. Les implications cliniques de ces résultats sont discutées ainsi que des recommandations à l’intention de ceux qui sont impliqués dans la provision des services en deuil.

Generic Finite Element Model for Mechanically Consistent Scaling of Composite Beam-to-column Joint with Welded Connection

To study the behaviour of beam-to-column composite connection more sophisticated finite element models is required, since component model has some severe limitations. In this research a generic finite element model for composite beam-to-column joint with welded connections is developed using current state of the art local modelling. Applying mechanically consistent scaling method, it can provide the constitutive relationship for a plane rectangular macro element with beam-type boundaries. Then, this defined macro element, which preserves local behaviour and allows for the transfer of five independent states between local and global models, can be implemented in high-accuracy frame analysis with the possibility of limit state checks. In order that macro element for scaling method can be used in practical manner, a generic geometry program as a new idea proposed in this study is also developed for this finite element model. With generic programming a set of global geometric variables can be input to generate a specific instance of the connection without much effort. The proposed finite element model generated by this generic programming is validated against testing results from University of Kaiserslautern. Finally, two illustrative examples for applying this macro element approach are presented. In the first example how to obtain the constitutive relationships of macro element is demonstrated. With certain assumptions for typical composite frame the constitutive relationships can be represented by bilinear laws for the macro bending and shear states that are then coupled by a two-dimensional surface law with yield and failure surfaces. In second example a scaling concept that combines sophisticated local models with a frame analysis using a macro element approach is presented as a practical application of this numerical model.

Connecting the Water and Carbon Cycles for the Generation of Food Security and Ecosystem Services

Water scarcity and food insecurity are pervasive issues in the developing world and are also intrinsically linked to one another. Through the connection of the water cycle and the carbon cycle this study illustrates that synergistic benefits can be realized by small scale farmers through the implementation of waste water irrigated agroforestry. The WaNuLCAS model is employed using La Huerta agroforestry site in Texcoco, South Central Mexico, as the basis for parameterization. The results of model simulations depicting scenarios of water scarcity and waste water irrigation clearly show that the addition of waste water greatly increases the agroforestry system’s generation of crop yields, above- and below-ground biomass, soil organic matter and carbon storage potential. This increase in carbon sequestration by the system translates into better local food security, diversified household income through payments for ecosystem services and contributes to the mitigation of global climate change.
