Os serviços de uma biblioteca por muito tempo ficaram restritos aos seus acervos em papel. Com o surgimento de novas ferramentas para auxiliar nos processos de recuperação da informação, oferecida por intermédio das tecnologias da informação, transformaram-se os métodos de trabalho e a forma de acesso aos serviços das bibliotecas, especificamente os serviços de referência e informação. Foi constatado que não há como prever se há como aliar o momento em que um usuário tem uma necessidade informacional com o momento em que tem recursos computacionais para acesso remoto aos serviços de referência e informação por ela oferecidos. Porém, observou-se que atualmente, os sistemas de comunicação sem fio e os dispositivos móveis são tecnologias que permitem acesso remoto e ininterrupto à Internet. Isso faz com que as bibliotecas esforcem-se para ampliar as condições de acesso e uso aos seus serviços, independente da restrição de seu horário de funcionamento para atendimento presencial ou de sua localização física. O objetivo geral concentrou-se em analisar aspectos de acesso e uso de serviços de referência e informação em ambientes digitais e digitais móveis em bibliotecas norte-americanas e brasileiras. A metodologia utilizada inicialmente foi a pesquisa bibliográfica e documental que ofereceram base para investigação das bibliotecas norte-americana e brasileira que tiveram seus serviços de referência e informação otimizados para ambientes digitais móveis. As tecnologias móveis proporcionaram a criação de ferramentas que valorizam o tempo e a independência de localização física para o usuário acessar e recuperar informação nas bibliotecas, tornando dispensável sua presença física... / The technological evolution propitiated the application of new tools to access the services available in the libraries. The services of a library for a long time were restricted to their collections on paper. With the emergence of new tools to assist in the process of information retrieval, offered through information technology, transforming the working methods and ways of access to library services, specifically the services of information and reference. It was noted that there is no way to predict if it’s possible to ally the moment when a user has an informational need with the moment in which computing resources to have remote access to information and referral services offered by it. However, it was noted that currently, the wireless communication systems and mobile devices are technologies that allow remote access and uninterrupted to the Internet. It makes the libraries try hard to improve the conditions of access and usage to their services, regardless of the restriction of their working time to attend in person or their physical location. The general objective focused on examining aspects of access and use of the services of reference and information in digital environment and in digital mobile libraries in United States and Brazil. Initially, the used methodology was the bibliographical and documental research that could provide the basis of research for Brazilian and American libraries who had their services of information and reference optimized for mobile digital environments. The mobile technologies propitiated the development of tools that valorized time and the independence of the user location to access and retrieve information in libraries, making expendable his physical presence. Therefore, the libraries that are attentive to the emergence of this mobile society, where information must go with the user, expanding... (Complete abstract click electronic access below)

abstract: The availability of a wide range of general purpose as well as accelerator cores on modern smartphones means that a significant number of applications can be executed on a smartphone simultaneously, resulting in an ever increasing demand on the memory subsystem. While the increased computation capability is intended for improving user experience, memory requests from each concurrent application exhibit unique memory access patterns as well as specific timing constraints. If not considered, this could lead to significant memory contention and result in lowered user experience. This work first analyzes the impact of memory degradation caused by the interference at the memory system for a broad range of commonly-used smartphone applications. The real system characterization results show that smartphone applications, such as web browsing and media playback, suffer significant performance degradation. This is caused by shared resource contention at the application processor’s last-level cache, the communication fabric, and the main memory. Based on the detailed characterization results, rest of this thesis focuses on the design of an effective memory interference mitigation technique. Since web browsing, being one of the most commonly-used smartphone applications and represents many html-based smartphone applications, my thesis focuses on meeting the performance requirement of a web browser on a smartphone in the presence of background processes and co-scheduled applications. My thesis proposes a light-weight user space frequency governor to mitigate the degradation caused by interfering applications, by predicting the performance and power consumption of web browsing. The governor selects an optimal energy-efficient frequency setting periodically by using the statically-trained performance and power models with dynamically-varying architecture and system conditions, such as the memory access intensity of background processes and/or coscheduled applications, and temperature of cores. The governor has been extensively evaluated on a Nexus 5 smartphone over a diverse range of mobile workloads. By operating at the most energy-efficient frequency setting in the presence of interference, energy efficiency is improved by as much as 35% and with an average of 18% compared to the existing interactive governor, while maintaining the satisfactory performance of web page loading under 3 seconds. / Dissertation/Thesis / Masters Thesis Electrical Engineering 2016

abstract: Road networks are valuable assets that deteriorate over time and need to be preserved to an acceptable service level. Pavement management systems and pavement condition assessment have been implemented widely to routinely evaluate the condition of the road network, and to make recommendations for maintenance and rehabilitation in due time and manner. The problem with current practices is that pavement evaluation requires qualified raters to carry out manual pavement condition surveys, which can be labor intensive and time consuming. Advances in computing capabilities, image processing and sensing technologies has permitted the development of vehicles equipped with such technologies to assess pavement condition. The problem with this is that the equipment is costly, and not all agencies can afford to purchase it. Recent researchers have developed smartphone applications to address this data collection problem, but only works in a restricted set up, or calibration is recommended. This dissertation developed a simple method to continually and accurately quantify pavement condition of an entire road network by using technologies already embedded in new cars, smart phones, and by randomly collecting data from a population of road users. The method includes the development of a Ride Quality Index (RQI), and a methodology for analyzing the data from multi-factor uncertainty. It also derived a methodology to use the collected data through smartphone sensing into a pavement management system. The proposed methodology was validated with field studies, and the use of Monte Carlo method to estimate RQI from different longitudinal profiles. The study suggested RQI thresholds for different road settings, and a minimum samples required for the analysis. The implementation of this approach could help agencies to continually monitor the road network condition at a minimal cost, thus saving millions of dollars compared to traditional condition surveys. This approach also has the potential to reliably assess pavement ride quality for very large networks in matter of days. / Dissertation/Thesis / Doctoral Dissertation Civil, Environmental and Sustainable Engineering 2018

Context. The mental effort offered by a user to identify an important email from the email message is considered significant or impossible. A user must enter the e-mail application to determine what type of e-mail they have received. To let the user identify the type of email via smartphone notification, micro-interactions are utilized. De augmentatie in UX of de e-mail notificaties is dan getest met de modificaties gemaakt aan de micro-interacties. Objectives. This study explores the microinteractions in an email notification of a smartphone that requires the modification of micro-interactions. These modifications have been implemented based on the design principles and usability heuristics of the existing literature. With this implementation, the augmentation in user experience of the modified design is determined. Methods. On conducting a systematic literature review, the experimental design of micro-interactions is prototyped. These prototypes are subjected to user interaction by conducting interviews that include performing certain tasks on the prototype and obtaining the user's perspectives regarding usability with an SUS scale. The data collected has been analyzed to obtain data on user experience increase. Since this data is tested for statistical significance to prove the theory and the evidence reinforce each other. Results. User interviews resulted in 100% of the users being able to perform the tasks successfully during the interaction with the prototypes. The modified design or email notifications achieve job performance time that is much less than the time used by the user for the existing design. Meanwhile, The SUS score for the modified design of micro-interactions with the existing design achieved the best imaginable score which reflects the rise in user experience of the e-mail notifications on a smartphone. On analysis, these achieved scores showed their statistical significance of the claim of increase in UX.Conclusions. This study concludes the reduction in cognitive load in a smartphone's email notifications by effective application or design principles in microinteractions. Regardless of the increased number of email arrivals on a device, a smartphone user can now identify the important e-mails on a smartphone directly from the email notifications. Following the Google's Material Design Principles resulted in increased user experience of e-mail notifications on a smartphone. However,

A Catarata ? uma patologia dos olhos que consiste na opacidade parcial ou total do cristalino (lente natural do olho) ou de sua c?psula. Pode ser desencadeada por v?rios fatores, como traumatismo, idade, diabetes mellitus, uso de medicamentos, entre outros. Sabe-se que o atendimento por oftalmologistas no Brasil nas ?reas rurais e mais pobres ? inferior ao necess?rio e muitos pacientes com doen?as trat?veis como a Catarata ficam sem diagn?stico e consequentemente sem tratamento. Neste contexto, esse projeto tem como proposta o desenvolvimento do OPTICA, um sistema de tele-oftalmologia que utiliza smartphones para detec??o de urg?ncias oftalmol?gicas, disponibilizando um aux?lio ao diagn?stico a Catarata utilizando sistemas inteligentes e t?cnicas de processamento de imagens. As imagens ser?o capturadas por um celular com uma lente especial acoplada a c?mera e juntamente com um question?rio com informa??es do paciente ser?o transmitidos de forma segura via a plataforma Sana Mobile (sana.mit.edu) para uma central online de laudos que disp?e de um programa inteligente de auxilio ao diagn?stico a Catarata e de m?dicos oftalmologistas que ir?o analisar as informa??es e emitir o laudo do paciente. Desta forma, o OPTICA permite levar atendendimento oftalmol?gico a popula??o menos favorecida e em ?reas remotas , melhorando a triagem de pacientes graves e aumentando o acesso ao diagn?stico e tratamento. / The increasing in world population, with higher proportion of elderly, leads to an increase in the number of individuals with vision loss and cataracts are one of the leading causes of blindness worldwide. Cataract is an eye disease that is the partial or total opacity of the crystalline lens (natural lens of the eye) or its capsule. It can be triggered by several factors such as trauma, age, diabetes mellitus, and medications, among others. It is known that the attendance by ophthalmologists in rural and poor areas in Brazil is less than needed and many patients with treatable diseases such as cataracts are undiagnosed and therefore untreated. In this context, this project presents the development of OPTICA, a system of teleophthalmology using smartphones for ophthalmic emergencies detection, providing a diagnostic aid for cataract using specialists systems and image processing techniques. The images are captured by a cellphone camera and along with a questionnaire filled with patient information are transmitted securely via the platform Mobile SANA to a online server that has an intelligent system available to assist in the diagnosis of cataract and provides ophthalmologists who analyze the information and write back the patient?s report. Thus, the OPTICA provides eye care to the poorest and least favored population, improving the screening of critically ill patients and increasing access to diagnosis and treatment.
