Mobile Web applications

This document presents the work that was elaborated at the company Present Technologies as part of the academic discipline Internship/Industrial Project for the Master’s degree in Informatics and Systems, Software Development branch, at Instituto Superior de Engenharia de Coimbra. The area of the mobile web applications has grown exponentially over the last few years turning it into a very dynamic field where new development platforms and frameworks are constantly emerging. Thus, the internship consisted in the study of two new mobile operating systems, Tizen and Firefox OS, as well as two frameworks for packaging of mobile web applications – Adobe PhoneGap and Appcelerator Titanium. These platforms are in the direct interest of Present Technology since it pretends to use them in its future projects in general and in the Phune Gaming project in particular. Since Television is one of the Present Technologies’ business areas, during the course of the internship it was decided to perform additionally a study of two Smart TV platforms, namely Samsung Smart TV and Opera TV, which was considered as a valuable knowledge for the company. For each of the platforms was performed a study about its architecture, supported standards and the development tools that are provided, nevertheless the focus was on the applications and for this reason a practical case study was conducted. The case studies consisted in the creation of a prototype or packaging of an application, for the case of the packaging tools, in order to prove the feasibility of the applications for the Present Technologies’ needs. The outcome of the work performed during the internship is that it raised the awareness of Present Technology of the studied platforms, providing it with prototypes and written documentation for the platforms’ successful usage in future projects.

HTML5, Javascript and modern browser technologies: toward a web based framework for device fingerprinting

Mentre navighiamo siamo veramente certi che i nostri dati e la nostra privacy siano al sicuro? I browser e le tecnologie di cui fanno uso possono rivelare una miriade di informazioni. Al crescere delle informazioni reperibili, si inizia a superare una massa critica che può permettere l'identificazione. Il device fingerprinting è proprio il rilevamento di questa tipologia di dati. HTML5 e le nuove API che esso mette a disposizione aumentano a dismisura le modalità per fare fingerprinting. Durante lo sviluppo della presente tesi è stato realizzato un framework molto potente che verrà mostrato nel dettaglio. Come a seguito di un disastro aereo, l'ingegneria aeronautica si mette all'opera per scovare i punti deboli allo scopo di rendere più robusti gli aerei di nuova generazione, noi con la presente tesi vogliamo dare il nostro contributo al miglioramento del web del futuro. Affinchè la nostra privacy sia veramente nelle nostre mani e possiamo essere artefici del nostro domani.

Type A aortic dissection model to improve endovascular research and technologies.

OBJECTIVE Type A aortic dissection is a life-threatening disease requiring immediate surgical treatment. With emerging catheter-based technologies, endovascular stent-graft implantation to treat aneurysms and dissections has become a standardized procedure. However, endovascular treatment of the ascending aorta remains challenging. Thus we designed an ascending aortic dissection model to allow simulation of endovascular treatment. METHODS Five formalin-fixed human aortas were prepared. The ascending aorta was opened semicircularly in the middle portion and the medial layer was separated from the intima. The intimal tube was readapted using running monofilament sutures. The preparations were assessed by 128-slice computed tomography. A bare-metal stent was implanted for thoracic endovascular aortic repair in 4 of the aortic dissection models. RESULTS Separation of the intimal and medial layer of the aorta was considered to be sufficient because computed tomography showed a clear image of the dissection membrane in each aorta. The dissection was located 3.9 ± 1.4 cm proximally from the aortic annulus, with a length of 4.6 ± 0.9 cm. Before stent implantation, the mean distance from the intimal flap to the aortic wall was measured as 0.63 ± 0.163 cm in the ascending aorta. After stent implantation, this distance decreased to 0.26 ± 0.12 cm. CONCLUSION This model of aortic dissection of the ascending human aorta was reproducible with a comparable pathological and morphological appearance. The technique and model can be used to evaluate new stent-graft technologies to treat type A dissection and facilitate training for surgeons.

Étude longitudinale de l’impact de la satisfaction envers les avantages sociaux novateurs sur l’intention de rester chez les travailleurs du secteur des technologies de l’information et des communications

The objective of this thesis is to understand the impact of satisfaction with innovative benefits on the intention to stay of the information and communications technology industry (ICT) workers. In order to investigate this question, a general research hypothesis was presented based on a literature review and on Blau’s social exchange theory (1964) and Maslow’s theory of needs (1943). The general research hypothesis states that satisfaction with innovative benefits increases intention to stay through time. The data used in this thesis were collected as part of a larger research on the relationships between compensation, training and skills development and attracting and retaining key employees. The longitudinal data come from an office located in Montreal of a major international company from the ICT sector. The study population consists of workers newly hired between April 1st, 2009 and September 30th, 2010. The results confirm the research hypothesis showing that satisfaction with innovative benefits increase intention to stay through time. Among the various innovative benefits studied, the results indicate that it is the satisfaction with the gym at work that best predicts intention to stay of workers. Other innovative benefits significantly related to intention to stay are the games library, the lounge, the medical clinic and the library in the workplace. Also, longitudinal analyses reveal that it is mainly the differences between the individual characteristics of the employees who best explain intention to stay than the differences across time of the same worker. This thesis concludes by discussing the best way for industrial relations managers to use the results in order to retain their employees. Then, the limits of the study and some directions for further research are also presented.
