I linguaggi per la programmazione web-based: l'alternativa Dart

Il Web ha subito numerose trasformazioni rispetto al passato. Si è passati da un Web statico, in cui l'unica possibilità era quella di leggere i contenuti della pagina, ad un Web dinamico e interattivo come quello dei social network. Il Web moderno è, ancora oggi, un universo in espansione. La possibilità di arricchire le pagine con contenuti interattivi, video, foto e molto altro, rende l'esperienza web sempre più coinvolgente. Inoltre la diffusione sempre più ampia di mobile device ha reso necessaria l'introduzione di nuovi strumenti per sfruttare al meglio le funzionalità di tali dispositivi. Esistono al momento tantissimi linguaggi di scripting e di programmazione, ma anche CMS che offrono a chiunque la possibilità di scrivere e amministrare siti web. Nonostante le grandi potenzialità che offrono, spesso queste tecnologie si occupano di ambiti specifici e non permettono di creare sistemi omogenei che comprendano sia client che server. Dart si inserisce proprio in questo contesto. Tale linguaggio dà a i programmatori la possibilità di poter sviluppare sia lato client sia lato server. L'obiettivo principale di questo linguaggio è infatti la risoluzione di alcune problematiche comuni a molti programmatori web. Importante in questo senso è il fatto di rendere strutturata la costruzione di programmi web attraverso l'uso di interfacce e classi. Fornisce inoltre un supporto per l'integrazione di svariate funzionalità che allo stato attuale sono gestite da differenti tecnologie. L'obiettivo della presente tesi è quello di mettere a confronto Dart con alcune delle tecnologie più utilizzate al giorno d'oggi per la programmazione web-based. In particolare si prenderanno in considerazione JavaScript, jQuery, node.js e CoffeeScript.

Authoring tools and management information systems: study of a generalizable architecture

The need to effectively manage the documentation covering the entire production process, from the concept phase right through to market realise, constitutes a key issue in the creation of a successful and highly competitive product. For almost forty years the most commonly used strategies to achieve this have followed Product Lifecycle Management (PLM) guidelines. Translated into information management systems at the end of the '90s, this methodology is now widely used by companies operating all over the world in many different sectors. PLM systems and editor programs are the two principal types of software applications used by companies for their process aotomation. Editor programs allow to store in documents the information related to the production chain, while the PLM system stores and shares this information so that it can be used within the company and made it available to partners. Different software tools, which capture and store documents and information automatically in the PLM system, have been developed in recent years. One of them is the ''DirectPLM'' application, which has been developed by the Italian company ''Focus PLM''. It is designed to ensure interoperability between many editors and the Aras Innovator PLM system. In this dissertation we present ''DirectPLM2'', a new version of the previous software application DirectPLM. It has been designed and developed as prototype during the internship by Focus PLM. Its new implementation separates the abstract logic of business from the real commands implementation, previously strongly dependent on Aras Innovator. Thanks to its new design, Focus PLM can easily develop different versions of DirectPLM2, each one devised for a specific PLM system. In fact, the company can focus the development effort only on a specific set of software components which provides specialized functions interacting with that particular PLM system. This allows shorter Time-To-Market and gives the company a significant competitive advantage.

Evaluation of a web-based application versus conventional instruction in the undergraduate curriculum of fixed prosthodontics

The present study aims to investigate the implications of web-based delivery of identical learning content for time efficiency and students' performance, as compared to conventional textbook resources.

The InterHerz project--a web-based psychological treatment for cardiac patients with depression: study protocol of a randomized controlled trial

Patients with heart disease often suffer from difficulties in psychological adaptation during cardiac rehabilitation. Mood disorders such as depression are known to be highly prevalent in cardiac patients and to have a negative impact on the progression of coronary heart disease. However, cardiac patients have difficulties to get psychological treatments due to low availability and motivational difficulties. Web-based interventions have been proven to be effective in treating depressive symptoms. Deprexis is a promising web-based psychological treatment which was devised for depressed patients. The aim of the study InterHerz is to examine if Deprexis is an effective psychological treatment to reduce stress and depression in cardiac patients.

Symptomatic management of fever by Swiss board-certified pediatricians: results from a cross-sectional, Web-based survey

Symptomatic management is often all that is recommended in children with fever. To date, only 2 nationwide surveys of pediatricians regarding their attitudes toward fever have been published.

Towards Self-Learning Radio-Based Localization Systems

Location-awareness indoors will be an inseparable feature of mobile services/applications in future wireless networks. Its current ubiquitous availability is still obstructed by technological challenges and privacy issues. We propose an innovative approach towards the concept of indoor positioning with main goal to develop a system that is self-learning and able to adapt to various radio propagation environments. The approach combines estimation of propagation conditions, subsequent appropriate channel modelling and optimisation feedback to the used positioning algorithm. Main advantages of the proposal are decreased system set-up effort, automatic re-calibration and increased precision.
