    No full text
    Il libro nasce da una riflessione sugli effetti economici e sociali indotti dalla introduzione e diffusione della rete Internet. In particolare delle conseguenze di fenomeni emergenti quali la diffusione di logiche peer-to-peer e quindi di strutture di relazione orizzontale tra una molteplicità di soggetti. Quali sono i motivi del diffuso interesse per l’Open Source? Innanzitutto l’Open Source fa riferimento al prodotto software. Il software è un’entità sempre più pervasiva nelle attività economiche e di relazione sociale. Il software è alla base di moltissime applicazioni, anche molto comuni, ed in particolare della comunicazione. Tutti usano software anche inconsapevolmente e l’utilizzo di software è destinato a crescere. Il modello di sviluppo Open Source è basato sullo sfruttamento di alcune diversità presenti in una comunità di sviluppo. L’eterogeneità dei soggetti, l’indipendenza e la volontarietà sono caratteristiche che vengono opportunamente valorizzate invece di essere contrastate come in un ambiente di sviluppo tradizionale. La comunità Open Source è un sistema auto-regolato e in grado di garantire efficienza e l’efficacia dei processi e quindi di produrre risultati ma anche di apprendere e quindi di ottenere risultati apprezzabili e di qualità. L’Open Source si propone quindi come un nuovo modo di organizzare la produzione di alcune tipologie di software con ottimi risultati. Il modello Open Source presenta caratteristiche tali che lo rendono difficilmente definibile come modello organizzativo. Tuttavia i principi e i meccanismi organizzativi su cui è basata la comunità Open Source possono influenzare i modelli organizzativi consolidati. Assumono rilevanza, in accordo con il modello Open Source, alcune caratteristiche quali la dimensione progettuale, la dinamica di entrata e uscita dei soggetti da un network in funzione dell’attrattività dei progetti e la rilevanza di meccanismi di integrazione basati sulla fiducia. Open Source stimola anche una nuova idea di organizzazione. I modelli concettuali con cui vengono studiate e descritte le organizzazioni non sono sufficienti a definire l’organizzazione di una comunità Open Source. Sono necessari nuovi approcci e modelli emergenti come quello sui sistemi complessi adattivi. Con lo sviluppo delle reti e in particolare di Internet si è osservato che non tutti i fenomeni sociali che si producono sono anche progettabili e pianificabili. In realtà sono in una certa misura “emergenti” e generati dalla rete di interazioni tra i soggetti. L’Open Source può essere interpretato nella logica di un sistema complesso. In termini di sviluppi e di linee evolutive si può osservare un crescente interesse della Pubblica Amministrazione per l’Open Source ed una parallela estensione del concetto di apertura a campi diversi dal software. In diversi paesi le Amministrazioni Pubbliche hanno iniziato un processo di graduale adozione di piattaforme Open Source. Le motivazioni per un’adozione del software Open Source sono essenzialmente quelle di consentire un più facile e libero accesso da parte dei cittadini ai dati gestiti dall’Amministrazione; la garanzia di continuità di gestione e mantenimento dei dati indipendentemente dalla soluzione e dai fornitori scelti; la garanzia di una maggiore sicurezza; la diffusione e il riuso delle tecnologie e della conoscenza. Per quanto concerne la diffusione del concetto di apertura si constata l’attivazione di un certo numero di progetti che applicano con successo i principi dell’Open Source in alcune attività legate alla conoscenza ed in particolare la raccolta, l’organizzazione, l’accreditamento, la diffusione e la produzione di conoscenza. Il dato più rilevante riguarda la produzione di contenuti e di conoscenza con modalità aperte in campi di recente sviluppo e dalle prospettive molto promettenti come quello della bioinformatica. Il lavoro è articolato in tre parti. La prima parte riguarda la descrizione del fenomeno Open Source a partire dalle sue origini storiche. Si descrive la composizione, il funzionamento, le motivazioni di una comunità Open Source. Da queste considerazioni emerge un processo di sviluppo del software notevolmente diverso dai processi tradizionali. Ci addentriamo quindi in una disamina dei modelli consolidati di sviluppo software e relativo confronto con i processi dell’Open Source. Poiché sono i processi che producono la qualità dei risultati il confronto è completato con la valutazione della qualità dei prodotti e dei relativi criteri. La seconda parte è di natura interpretativa. Si analizza l’impatto dell’Open Source su competizione e strategie delle imprese in relazione anche alla gestione dei diritti di proprietà. Si approfondisce l’analisi del modello Open Source da un punto di vista organizzativo introducendo anche la prospettiva dei sistemi complessi adattativi. E si illustrano i principali aspetti di cambiamento dell’organizzazione del lavoro. La terza parte riguarda l’evoluzione del fenomeno Open Source. Tale evoluzione riguarda l’entrata in scena di nuovi potenti soggetti come la Pubblica Amministrazione e la diffusione dei concetti portanti dell’Open Source ad altri campi di applicazione

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses

    No full text
    Following an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied

    Includes author's vita"Submitted to the College of Engineering of Texas A&M University in partial fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc. during the period September 1975 through May 1976 is presented. During this nine month internship the author worked as an Engineer II in the Industrial Processes discipline of this large consulting engineering firm... The author's prime responsibility was as one of three lead design engineers on the design of a large wastewater treatment facility for a pulp mill in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design of individual treatment units and associated piping and pumping. The purpose of the project was to provide wastewater treatment capabilities that would satisfy the effluent limitations (standards) imposed upon the mill by the State of Washington Department of Ecology and the U.S. Environmental Protection Agency. The author's assignment also entailed necessary interaction with the project manager and other CH���M HILL design engineers and support staff members, the client's representatives, and representatives of two other consulting engineering firms working on the project. Thus, the internship position at CH���M HILL provided considerable experience coordinating the author's work with the work of other engineers, guiding the design and administrative efforts of a support staff, and interacting regularly with the client and other consulting firms. This broad exposure to a variety of engineering and organizational problems provided a valuable educational experience

    Glass sky animation studios

    No full text
    Glass Sky Animation Studios is a fictitious, independent animation studio located in the West Loop neighborhood of Chicago, Illinois. Their hope is to bring a new world of diversity and creativity to Chicago while building on the stories and lives of all who live there. The project addresses a potential possible facility in the West Loop, with a sizable renovation to the first and second floors of the building. Many existing animation studios do not foster collaboration and do not provide flexible and adaptable furniture configurations. Spaces are dark and closed off, with animators sitting in uncomfortable chairs in front of a computer screen for the better part of their day. My research and design seek to bring forth a new generation of storytellers and tales that represent marginalized members of society and showcase their history and experiences. The improved studio spaces will allow the animators to be healthier, happier, and more productive in the workplace, and all who come through the doors will feel welcome and accepted. Additionally, a space that openly celebrates such cultural diversity and inclusion will work to improve the visibility of women, minorities, and members of the LGBTQ+ community in the animation industry.Thesis (B.?)Honors Colleg

    Transition to turbulence in a qblique shock-wave/boundary-layer interaction at M=15

    No full text
    Direct numerical simulations are carried out for different forcing techniques to trigger transition during the interaction between an oblique shock-wave and a laminar boundary-layer at M = 1.5. Three forcing methods are used: a) forcing of oblique unstable modes, whose shape and behaviour are determined by the local linear stability theory, b) broadband free-stream acoustic disturbances, and c) a cold plasma flow control device. While the oblique-mode breakdown is dominant for low-amplitude forcing, long streaky structures drive the transition process in a high-amplitude disturbance environment. LES are also performed on the experimental setup by the Institute of Theoretical and Applied Mechanics (ITAM) from Novosibirsk State University with cold plasma actuation. As well as the disturbance type, the effect of Reynolds number and forcing amplitude will be investigated
