RESTful PUBLISH/SUBSCRIBE FRAMEWORK FOR MOBILE DEVICES2013 November 1900 (has links)
The growing popularity of mobile platforms is changing the Internet user’s computing experience. Current studies suggest that the traditional ubiquitous computing landscape is shifting towards more enhanced and broader mobile computing platform consists of large number of heterogeneous devices. Smartphones and tablets begin to replace the desktop as the primary means of interacting with IT resources. While mobile devices facilitate in consuming web resources in the form of web services, the growing demand for consuming services on mobile device is introducing a complex ecosystem in the mobile environment. This research addresses the communication challenges involved in mobile distributed networks and proposes an event-driven communication approach for information dissemination. This research investigates different communication techniques such as synchronous and asynchronous polling and long-polling, server-side push as mechanisms between client-server interactions and the latest web technologies namely HTML5 standard WebSocket as communication protocol within a publish/subscribe paradigm. Finally, this research introduces and evaluates a framework that is hybrid of REST and event-based publish/subscribe for operating in the mobile environment.

A linear logic approach to RESTful web service modelling and compositionZhao, Xia January 2013 (has links)
RESTful Web Services are gaining increasing attention from both the service and the Web communities. The rising number of services being implemented and made available on the Web is creating a demand for modelling techniques that can abstract REST design from the implementation in order better to specify, analyse and implement large-scale RESTful Web systems. It can also help by providing suitable RESTful Web Service composition methods which can reduce costs by effi ciently re-using the large number of services that are already available and by exploiting existing services for complex business purposes. This research considers RESTful Web Services as state transition systems and proposes a novel Linear Logic based approach, the first of its kind, for both the modelling and the composition of RESTful Web Services. The thesis demonstrates the capabilities of resource-sensitive Linear Logic for modelling five key REST constraints and proposes a two-stage approach to service composition involving Linear Logic theorem proving and proof-as-process based on the π-calculus. Whereas previous approaches have focused on each aspect of the composition of RESTful Web Services individually (e.g. execution or high-level modelling), this work bridges the gap between abstract formal modelling and application-level execution in an efficient and effective way. The approach not only ensures the completeness and correctness of the resulting composed services but also produces their process models naturally, providing the possibility to translate them into executable business languages. Furthermore, the research encodes the proposed modelling and composition method into the Coq proof assistant, which enables both the Linear Logic theorem proving and the π-calculus extraction to be conducted semi-automatically. The feasibility and versatility studies performed in two disparate user scenarios (shopping and biomedical service composition) show that the proposed method provides a good level of scalability when the numbers of services and resources grow.

Replacing a monolithic web application with a new backend frameworkLu, Wei January 2018 (has links)
Web Technologies, particularly the web application, have become an essential component of the business world in our daily life. By utilizing the web application, it is convenient for human beings to search the information, make the payment and communicate with others through Internet. However, according to a report from the Society of Digital Agencies, 77% of companies believe that poor website user experience is a weakness for their clients, which making poor user experience the most significant weakness agencies identified. As for current monolithic web application of booking course system, all the components are tightly integrated in one module so that it is difficult to maintain and make changes for both currents functions and new functions. In addition, the algorithms of some functions are vulnerable. For example, the offer code corresponding to the one course can be used for another course that should not be on sales promotion. This thesis presents a decoupling of the monolithic architecture. The monolithic architecture composes all in one piece and implement an alternative solution for booking course system based on representational state transfer web service, spring, WordPress and bootstrap frameworks. Moreover, this thesis focuses on improving the vulnerable algorithm for the old booking system. In the end, some non-functional requirement like user experience will also be taken in consideration. In this thesis, the result proves the feasibility of the decoupling monolithic architecture by exploiting RESTful web services. / Webbtekniker, speciellt webbapplikationer, har blivit en viktig komponent för företags dagliga verksamhet. Genom att använda webbapplikationer blir det enkelt för människor att söka information, göra betalningar och kommunicera med andra på Internet. Men enligt en rapport från the Society of Digital Agencies upplever 77% av företagen att en dåligt webbupplevelse påverkar slutkunderna, vilket gör webbupplevelsen till den största påverkande faktorn som the Society of Digital Agencies har identifierat. Det existerande webbokningssystemet är en monolit, där samtliga komponenter är tätt integrerade i en modul. Denna integrerade arkitektur gör det svårt att underhålla och förändra systemet. I tillägg finns det sårbarheter i systemet, som till exempel att rabattkoder för en kurs kan användas även på andra kurser, som inte ska rabatteras. Uppsatsen presenterar en frikoppling av den integrerade strukturen för systemet. Den nya arkitekturen bygger på representational state transfer web services, spring, wordpress samt bootstrap ramverken. I tillägg förbättras även de sårbara algoritmerna i det existerande bokningssystemet. Slutligen inkluderas ickefunktionella krav på användarvänlighet. I den här avhandlingen visar resultatet att det är möjligt att avmontera monolitisk arkitektur genom att utnyttja RESTful webbtjänster.

Smart Parking SystemYadavalli, Siri Chandana January 1900 (has links)
Master of Science / Department of Computing and Information Sciences / Daniel A. Andresen / Locating a parking spot during peak hours in most populated areas like shopping malls, universities, exhibitions or convention centers is difficult for the drivers. The difficulty rises from not knowing where the available spots may be at that required time. Smart parking is a solution to metropolitan cities to reduce congestion, cut vehicle emission totals and save persons' time by helping them in finding a spot to park.
Smart Parking is a parking system, usually a new one that is equipped with special structured devices (things) to detect the available parking slots at any parking area. This is an application based on Internet of Things (IoT) that in Real-Time environment have sensors and devices embedded into parking spaces, transmitting data on the occupancy status; and the vehicle drivers can search for parking availability using their mobile phones or any infotainment system that is attached to the vehicle. Hence the driver would know where there is an available spot to park his vehicle in less time, reducing the energy consumption and air pollution. The Client or the sensor posts the parking slot occupancy status to a web service URL. The Java based web service is built using Spring and Hibernate to connect to the backend system. The web service (.war) file is deployed on Apache Tomcat Server and the backend used is MySQL database.

A formulation for efficient adaptive metamodelling in engineering designMakin, Thomas January 2014 (has links)
This thesis presents the research and development of robust metamodelling tools for engineering design. Metamodelling in engineering is typically used for reducing computational cost of highly expensive analyses or simulations. Metamodels have been shown to be effective in these problems where an approximation constructed from a limited set of true data points is used in support of optimisation. The inspiration for this work is drawn from the optimisation of aircraft wing structures, constructed using large numbers of rectangular stiffened panels. When optimising such structures to produce a minimum weight design, it is necessary to evaluate multiple design constraints such as buckling load, damage tolerance and repairability. The total computational cost for this aspect of the analysis can become considerable when a large number of evaluations is required and can creates a bottleneck in the optimisation workflow. In response to this industrial design problem, a specification is proposed for an efficient and adaptive metamodelling formulation. Following an extensive literature review the multilevel Radial Basis Function (mRBF) model is highlighted as a promising candidate for further investigation. The mRBF formulation is discussed in detail, and a comparative study is presented comparing mRBF to more established modelling techniques. mRBF is then put to work on a range of optimisation test problems, including an industrial scale multi-panel wing design scenario. Emphasis is placed on the adaptive acquisition of model data as the optimisation process progresses. Implementation details and software development processes are also presented in detail. The case is made for decoupled modelling workflows, and a RESTful web based mRBF modelling framework. Finally the performance of the proposed modelling scheme is compared to the original specification, and recommendations are made for further investigation.

Teste baseado em modelos para serviços RESTful usando máquinas de estados de protocolos UML / Model-based testing of RESTful web services using UML protocol state machinesPinheiro, Pedro Victor Pontes 15 April 2014 (has links)
A Arquitetura Orientada a Serviços (SOA) é um estilo arquitetural formado por um conjunto de restrições que visa promover a escalabilidade e a flexibilidade de um sistema, provendo suas funcionalidades como serviços. Nos últimos anos, um estilo alternativo foi proposto e amplamente adotado, que projeta as funcionalidades de um sistema como recursos. Este estilo arquitetural orientado a recursos é chamado de REST. O teste de serviços web em geral apresenta vários desafios devido a sua natureza distribuída, canal de comunicação pouco confiável, baixo acoplamento e a falta de uma interface de usuário. O teste de serviços RESTful (serviços que utilizam o REST) compartilham estes mesmos desafios e ainda necessitam que suas restrições sejam obedecidas. Estes desafios demandam testes mais sistemáticos e formais. Neste contexto, o teste baseado em modelos (TBM) se apresenta como um processo viável para abordar essas necessidades. O modelo que representa o sistema deve ser simples e ao mesmo tempo preciso para que sejam gerados casos de teste com qualidade. Com base nesse contexto, este projeto de mestrado propõe uma abordagem baseada em modelos para testar serviços RESTful. O modelo comportamental adotado foi a máquina de estados de protocolos UML, capaz de formalizar a interface do serviço enquanto esconde o seu funcionamento interno. Uma ferramenta foi desenvolvida para gerar automaticamente os casos de teste usando critérios de cobertura de estados e transições para percorrer o modelo / Service Oriented Architecture (SOA) is an architectural style consisting of a set of restrictions aimed at promoting the scalability and flexibility of a system, providing its functionalities as services. In recent years, an alternative style was proposed and widely adopted, which designs the system\'s functionalities as resources. This resource oriented architectural style is called REST. In general, the test of web services has several challenges due to its distributed nature, unreliable communication channel, low coupling and the lack of a user interface. Testing RESTful web services (services that use REST) share these same challenges and also need to obey the REST constraints. These challenges require a more systematic and formal testing approach. In this context, model based testing presents itself as a viable process for addressing those needs. The model that represents the system should be simple and precise enough to generate quality test cases. Based on this context, this work proposes a model based approach to test RESTful web services. The behavioral model used was the UML protocol state machine, which is capable to provide a formalization of the service interface, while hiding its internal behaviour. A tool was developed to automatically generate test cases using the state and transition coverage criteria to traverse the model

RestMDD: Ambiente colaborativo para o apoio no desenvolvimento de serviços Web RESTful / RestMDD: collaborative environment to support the development of RESTful web servicesSanchez, Robson Vinicius Vieira 02 September 2013 (has links)
Na ultima década o paradigma de computação orientada a serviços (SOC - Service Oriented Computing) tem ganhado cada vez mais espaço na indústria e na academia, a fim de solucionar o problema da falta de comunicação entre os diversos sistemas de informação presentes dentro de um ambiente corporativo. Graças aos recentes avanços da chamada \"Web 2.0\" um novo estilo arquitetural chamado de Arquitetura orientada a Web (WOA - Web Oriented Architecture) foi proposto a fim de garantir uma maneira simples de conectar os componentes de software dinamicamente. Esse estilo tem como um dos princípios o uso de serviços Web RESTful, a fim de conseguir uma interface funcional simples e uniforme. Este trabalho apresenta um ambiente colaborativo de apoio ao desenvolvimento de serviços Web RESTful utilizando o paradigma de desenvolvimento orientado a modelos (MDD - Model Driven Development). Pretende-se mostrar os benefícios do MDD aplicado a Engenharia Web e também as vantagens apresentadas pela colaboração nesse cenário.
