Composizione musicale e streaming peer-to-peer con web audio e webrtc

La tesi descrive lo sviluppo di un'applicazione web per comporre musica tramite la tecnica del "live looping" che fornisce anche la possibilità di effettuare lo streaming di ciò che si crea in tempo reale e in maniera peer-to-peer. L'applicazione in oggetto (chiamata WebLooper) fa uso di due tecnologie web emergenti in ambito multimediale: Web Audio e WebRTC, attualmente in attesa di diventare standard W3C.

Confronto di performance tra applicazioni web SQL e NoSQL su grandi quantità di dati

Lo scopo di questa tesi è di mettere a confronto le performance, su grandi quantità di dati, tra applicazioni web basate su database a modello relazionale, noti come RDBMS, e applicazioni web basate su database a modello non-relazionale, meglio conosciuti con l'appellativo NoSQL. Sono stati selezionati sette casi d'uso appartenenti ad una applicazione reale per effettuare il confronto di prestazioni tra i seguenti database: MySQL, Microsoft SQL Server, OrientDB, MongoDB e BaseX.

Uso di strumenti web per la reingegnerizzazione platform independent di applicazioni multipiattaforma.

La tesi parla del processo di modernizzazione di un software aziendale verso tecnologie web. Il trattato prosegue poi con lo studio di automatizzazione del processo, tramite strumenti di descrizione grammatiche (e DSL) come Xtext.

La gestione delle relazioni tra soggetto produttore e risorse archivistiche nel semantic web. Un modello ontologico

La ricerca nel campo del cultural heritage management ha adottato negli ultimi decenni le tecnologie web quali strumenti privilegiati per stabilire i nuovi approcci e indirizzi nella valorizzazione della conoscenza. Questa tesi si colloca nell'ambito interdisciplinare tra le scienze umanistiche e informatiche e si fonda sulla consapevolezza del reciproco arricchimento che può derivare dal continuo confronto, le une disponendo di mezzi più espressivi e popolari per divulgare il proprio patrimonio e le altre usufruendo di “materia prima” autorevole (ossia dati strutturati di qualità e alto livello di fiducia) in fase di sperimentazione. Lo studio dei punti di tangenza tra le discipline muove da due ambiti precisi, ovvero le applicazioni informatiche nel campo dell'archivistica e gli sviluppi del semantic web nel settore delle digital humanities.

Mobile CSCW e sincronizzazione dati per il soccorso in emergenza: un caso di studio

L'obiettivo principale di questa tesi è quello di approfondire il tema della comunicazione e sincronizzazione dati nel contesto di uno specifico caso di studio di sistema informatico a supporto del lavoro cooperativo per il soccorso in emergenza: a partire dai requisiti del caso applicativo, secondo cui agli operatori deve essere possibile utilizzare il sistema anche a fronte di disconnessioni dei propri dispositivi mobili, emerge infatti la necessità di un middleware a cui il livello applicativo demandi le funzionalità di sincronizzare le informazioni prodotte durante le operazioni, in modo da promuovere uno scambio di informazioni che migliori e supporti l'azione del singolo e conseguentemente del team. Quindi, dopo aver introdotto la tematica ed analizzato il caso di studio da affrontare, viene descritta l'esplorazione del panorama tecnologico volta alla ricerca di strumenti o approcci che possano mitigare la complessità nella realizzazione di questa funzionalità. Nel panorama tecnologico considerato, comprendente framework per servizi web, MOM e database, uno strumento di particolare interesse è stato individuato in CouchDB, un database NoSQL, grazie alle sue funzionalità di replica e sincronizzazione e alla presenza di una libreria per lo sviluppo su dispositivi mobili: su di esso è stata effettuata una breve fase di sperimentazione volta a saggiarne in maniera più concreta le potenzialità anche in relazione alla valutazione di fattibilità per il caso applicativo considerato.

PALI—a database of Phylogeny and ALIgnment of homologous protein structures

PALI (release 1.2) contains three-dimensional (3-D) structure-dependent sequence alignments as well as structure-based phylogenetic trees of homologous protein domains in various families. The data set of homologous protein structures has been derived by consulting the SCOP database (release 1.50) and the data set comprises 604 families of homologous proteins involving 2739 protein domain structures with each family made up of at least two members. Each member in a family has been structurally aligned with every other member in the same family (pairwise alignment) and all the members in the family are also aligned using simultaneous super­position (multiple alignment). The structural alignments are performed largely automatically, with manual interventions especially in the cases of distantly related proteins, using the program STAMP (version 4.2). Every family is also associated with two dendrograms, calculated using PHYLIP (version 3.5), one based on a structural dissimilarity metric defined for every pairwise alignment and the other based on similarity of topologically equivalent residues. These dendrograms enable easy comparison of sequence and structure-based relationships among the members in a family. Structure-based alignments with the details of structural and sequence similarities, superposed coordinate sets and dendrograms can be accessed conveniently using a web interface. The database can be queried for protein pairs with sequence or structural similarities falling within a specified range. Thus PALI forms a useful resource to help in analysing the relationship between sequence and structure variation at a given level of sequence similarity. PALI also contains over 653 ‘orphans’ (single member families). Using the web interface involving PSI_BLAST and PHYLIP it is possible to associate the sequence of a new protein with one of the families in PALI and generate a phylogenetic tree combining the query sequence and proteins of known 3-D structure. The database with the web interfaced search and dendrogram generation tools can be accessed at http://pa uling.mbu.iisc.ernet.in/~pali.

PIP-DB:the protein isoelectric point database

A protein's isoelectric point or pI corresponds to the solution pH at which its net surface charge is zero. Since the early days of solution biochemistry, the pI has been recorded and reported, and thus literature reports of pI abound. The Protein Isoelectric Point database (PIP-DB) has collected and collated these data to provide an increasingly comprehensive database for comparison and benchmarking purposes. A web application has been developed to warehouse this database and provide public access to this unique resource. PIP-DB is a web-enabled SQL database with an HTML GUI front-end. PIP-DB is fully searchable across a range of properties.

Radioimmunotherapy confers long-term survival to lymphoma patients with acceptable toxicity: registry analysis by the international radioimmunotherapy network.

The Radioimmunotherapy Network (RIT-N) is a Web-based, international registry collecting long-term observational data about radioimmunotherapy-treated patients with malignant lymphoma outside randomized clinical studies. The RIT-N collects unbiased data on treatment indications, disease stages, patients' conditions, lymphoma subtypes, and hematologic side effects of radioimmunotherapy treatment. Methods: RIT-N is located at the University of Gottingen, Germany, and collected data from 14 countries. Data were entered by investigators into a Web-based central database managed by an independent clinical research organization. Results: Patients (1,075) were enrolled from December 2006 until November 2009, and 467 patients with an observation time of at least 12 mo were included in the following analysis. Diagnoses were as follows: 58% follicular lymphoma and 42% other B-cell lymphomas. The mean overall survival was 28 mo for follicular lymphoma and 26 mo for other lymphoma subtypes. Hematotoxicity was mild for hemoglobin (World Health Organization grade II), with a median nadir of 10 g/dL, but severe (World Health Organization grade III) for platelets and leukocytes, with a median nadir of 7,000/mu L and 2.2/mu L, respectively. Conclusion: Clinical usage of radioimmunotherapy differs from the labeled indications and can be assessed by this registry, enabling analyses of outcome and toxicity data beyond clinical trials. This analysis proves that radioimmunotherapy in follicular lymphoma and other lymphoma subtypes is a safe and efficient treatment option.

Limnological research in the Iberian Peninsula: a ten-year survey of published literature.

Research on limnology in southern Europe had achieved a notable presence in the international arena before the onset of the current dramatic cuts in public investment in science. We assessed the limnological research published in peer-reviewed journals by Spanish and Portuguese (i.e., Iberian) researchers during the decade prior to the economic recession (2000 to 2009). The Thompson Reuters Web of Knowledge database was used to retrieve all publications on limnology authored by researchers affiliated with Spanish or Portuguese institutions independently of the geographical setting of the study. The publishing pattern was characterised in terms of authors, journals, and citation statistics. In addition, a thematic characterisation of the research was performed by a manual assignation of several categorical descriptors combined with a blind word count analysis. Iberian researchers produced an annual mean of 278 papers on limnology. Papers were published in journals that had impact factors ranging from 0.1 to 31.4, with a mean of 2.0. Based on citations, the impact of the Iberian limnological research was not due to a few highly cited papers but rather to a wide number of publications; each paper received a mean of 8 citations. The Iberian limnological research involved up to 5460 researchers, with a mean of 4.3 authors per paper. The research largely focused on fluvial systems, with 47 % of total publications (2778) devoted to these ecosystems. There was a dominant focus on local, within-system aspects of study sites and the research was mostly restricted to the Iberian Peninsula; larger spatial scales of analysis (i.e., landscape, regional, or global) tended to be overlooked. Iberian research addressed fundamental (75 %) rather than applied (17 %) or methodological (5 %) questions and was vastly dominated by observational approaches (75 %). Interestingly, Iberian limnological research increased its scientific productivity during the analysed decade at a higher rate than its international counterpart (increase of 119 %). Overall, Iberian research on limnology appeared to be in good health during the analysed decade. Certain areas have been more studied than others, which opens opportunities to develop new research.
