Previous issue date: 2012-03-05 / The increasing interest on mobile technologies and the evolutionary context in which mobile applications are developed have made the usability evaluation of these applications an important research area. However, usability evaluations are often avoided by developers
or companies due to their lack of experience in the field. This thesis presents the UBICUA (Usability-Based Inspection CUstomizable Approach) technique, an inspection technique
specifically proposed to assess the usability of hybrid mobile web applications (i.e., applications that rely on the Internet, such as widgets). Also, our approach is customizable
by the inspector s knowledge, which results in a greater usability problem identification even by non-expert users. To support our UBICUA technique s creation process, this research has adopted an evidence-based methodology. Then, this thesis describes how UBICUA was created based on the outcome of a secondary study, two results feasibility studies and observation studies. Our ultimate goal is to increase the quality of hybrid mobile web applications and improve the user s interaction in this technology. We also present the
guidelines and resources developed to support the execution of usability inspections of mobile applications in software development organizations. / O crescente interesse em tecnologias móveis e o contexto evolutivo no qual aplicações móveis são desenvolvidas têm tornado a avaliação de usabilidade destas aplicações um importante campo de pesquisa. No entanto, as avaliações de usabilidade são normalmente evitadas pelos desenvolvedores ou empresas, devido à falta de experiência na área. Esta dissertação apresenta a técnica UBICUA (Usability-Based Inspection CUstomizable Approach), específica para avaliação de usabilidade de aplicações Web móveis híbridas (i.e.,
aplicações locais que dependem da Internet). Esta nova abordagem é customizada pelo conhecimento do inspetor visando maior identificação de problemas de usabilidade, mesmo por inspetores com pouco conhecimento. Para a avaliação e evolução da UBICUA, esta pesquisa adotou uma metodologia baseada em evidências. Esta dissertação mostra como a UBICUA foi definida e aprimorada a partir dos resultados de diferentes estudos experimentais: mapeamento sistemático de literatura, estudos de viabilidade e de
observação. O objetivo final é aumentar a qualidade das aplicações Web em dispositivos móveis e melhorar a interação dos usuários com estas tecnologias. Adicionalmente, são
apresentadas diretrizes e recursos desenvolvidos para apoiar a realização de inspeções de usabilidade de aplicações deste porte.

Evaluating Web-latency reducing Protocols in Mobile EnvironmentsShamsher, Usama, Wang, Xiao Jun January 2013 (has links)
User perceived latency is the most prominent performance issue influencing the World Wide Web (www) presently. Hyper-Text Transfer Protocol(HTTP) and Transmission Control Protocol (TCP) have been the backbone of web transport for decades, thus received a lot of attention recently due to end-to-end performance degradation in mobile environments. Inefficiencies of HTTP and TCP strongly affect web response time mainly in resource limited devices. HTTP compression reduces some of the burden imposed by TCP slow start phase. However, compression is still an underutilized feature of the web today [1]. In order to fulfill the end user expectations, we can optimize HTTP to improve Page Load Time (PLT), low memory usage and better network utilization. SPDY, a web latency reducing protocol and HTTP pipelining are a recent proposal to provide faster information exchange over web. Through the course of this work, we present a comprehensive study of new approaches to reduce mobile web latency. At first, we measure the PLT after implementing SPDY, HTTP and HTTP pipelining. Secondly, we also analyze the performance of these protocols after tuning the network parameters like bandwidth and round-trip time (RTT). Finally, we compare the performance of HTTP and other latency reducing protocols. We have conducted all experiments over DummyNet under user-configured network conditions. We critically discuss the challenges of shifting from HTTP to these latency-reducing protocols.

Responsiv webbdesign : Tekniska designaspekterWallin, Christoffer January 2012 (has links)
Det blir allt vanligare att ägare till webbplatser anpassar sin webbplats till lågupplösta enheter som t. ex mobiltelefoner. För att genomföra en anpassning finns flera tekniska alternativ. I denna uppsats har det undersökts vilka tekniska aspekter som kan utgöra eventuella hinder när utvecklare möter webbyråkunders krav på upplösningsoberoende design med en av teknikerna, nämligen responsiv webbdesign. Arbetet innefattar en intervju med en webbyråkund som resulterade i en kravspecifikation som sedan stod till grund för en prototyp, där tekniken responsiv webbdesign testades och utvärderades. På grund av varierande stöd för CSS i skilda webbläsare samt flera webbplatsers komplicerade struktur visar resultatet på flera utmanande tekniska aspekter, som till exempel hanteringen av bilder och iframes. / It is becoming increasingly common for web site owners to customize their site to low-resolution devices such as mobile phones. To implement such an adjustment there are several technical options. This paper examines the technical aspects that can constitute an obstacles for web developers when they meet their customers' demands for resolution-independent design, with responsive web design. The work includes a interview with a client that resulted in a product specification, which then was used as the basis for a prototype. In which responsive web design was tested and evaluated as a technical option. The study revealed several technical aspects that can be challenging,e.g. pictures and iframes,so due to varying support for CSS in different browsers and many web sites complex structure.

Novel tools for interventional magnetic resonance imagingRube, Martin January 2014 (has links)
Magnetic Resonance Imaging (MRI) provides unique advantages such as superior soft tissue contrast, true multiplanar imaging, variable contrast mechanisms, measurement of temperature changes, perfusion and diffusion, and no ionizing radiation. Despite considerable research efforts in the field of interventional MRI, numerous challenges remain including restricted access to the patient, high acoustic noise and a shortage of MRI-safe devices. Novel methods and devices are presented in this thesis with the primary objective of enabling effective MRI-guided interventions, particularly abdominal needle and common catheter-based endovascular interventions. Firstly, a set of MRI-safe devices (guidewires, micro guidewires, catheters and micro catheters) were developed with passive or inductively coupling resonant markers for MRI visualisation. Secondly, a method was implemented for wireless tracking and dynamic guidance of instruments. Thirdly, a framework of technologies was developed for in-room display, wireless MRI remote control and multi-user communication along with a dedicated user interface and imaging protocol. These implementations were assessed in regards to MRI-safety, performance and usability and evaluated for MRI-guided liver biopsies, balloon angioplasty procedures and also for mechanical thrombolysis. Flow phantoms, Thiel soft-embalmed human cadavers with partially re-established perfusion and a porcine model were used for in vitro, ex vivo and in vivo validation, respectively. The results demonstrate that these interventions are experimentally feasible and practical when using the presented developments: automated device tracking and equipment designed for MRI-guided interventions streamlined procedural workflow. Specifically, it was shown that fast and accurate needle placements along complex trajectories were feasible using a wireless interactive display and control device with a dedicated user interface for interventions. Moreover, safe and efficacious balloon angioplasties of the iliac artery were practical using the described framework of technologies along with a dedicated MRI protocol. Finally, it was demonstrated that these developments could be adapted and applied to MRI-guided endovascular mechanical thrombolysis of the middle cerebral artery. The technologies, described in this thesis have been shown to overcome many of the present limitations and should therefore be useful for enabling MRI-guided interventions while not further constraining the operating physician in an already complex environment. Nevertheless, it is acknowledged that many crucial issues remain to be solved in the field of iMRI and in the context of the presented research. In particular further device optimisations, improvements of the tracking implementation along with further in vivo evaluations are required before moving towards clinical evaluation. This thesis sets the groundwork for moving ahead with the eventual clinical realisation of optimised MRI-guided interventions.

Humor-Centered Design: Using Humor as a Rhetorical Approach in DesignDelaney, Chelsey 01 May 2011 (has links)
My thesis pursues the development of a tool to empower designers and non-designers to better understand humor’s function in design and to encourage the use of humor as a rhetorical device to undertake social problems. Humor research is a field that is largely based on linguistic studies, but because of its multidisciplinary stretch in the past decade has displayed a broad rhetorical influence; however, it has yet to form a substantial relationship with design. Through a literature review of linguistic, rhetorical, and design theories, I identified a set of heuristics that guide how humor should operate in design. I then tested the effectiveness of the heuristics, and with their final revision, applied them to designing for motivational problems associated with public displays of political mobilization. My user research inferred the creation of a mobile instructional tool that guides the collaborative and/or individual production of political communication artifacts (e.g. rally signs), which use humor to confront socially complex issues. The artifacts’ implicit intent is to motivate political mobilization and to found and/or empower communities. My project focus entails the creation and testing of the tool on the individual level. Whether the artifacts created produce the desired effect regarding mobilization and community strength is unknown; Future work should lend itself to testing humorous design’s effect on political mobilization and ability to empower communities.
