Full textAbstract:
Det har genom åren förts en diskussion om RAD och andra snabba utvecklingsmetoder. Det här arbetet handlar det om att utveckla IS med hjälp av RAD-verktyg. Utveckling kommer att göras av olika personer med varierande IT-erfarenheter. Genom att låta personerna vara med i observationen finns det en möjlighet att se vilka som klarar av att utveckla ett IS liknande scenariot som används i studien. Ett scenario har utvecklats och verifierats med hjälp av en IT-forskare på Högskolan i Skövde, att det är ett rimligt scenario. Vidare har det i sin tur används som underlag till intervjuer för att verifiera ifall det är ett troligt och rimligt scenario som har en verklighetsanknytning. Ett antal deltagare med olika IT-erfarenheter har fått möjligheten att lösa problemet i scenariot med hjälp av ett RAD-verktyg. Deltagarna har blivit indelade i tre grupper utifrån deras IT-erfarenheter, de tre grupperna är: inga databaskunskaper, grundläggande databaskunskaper och avancerad databaskunskaper. Deltagarna har en begränsad tid på sig, under den tiden ska de försöka lösa problemet genom att bygga ett IS. I resultatet framgår det vilken typ av IT-kunskapsnivå som är rimlig att ha om användaren ska utveckla ett IS likt scenariot. Syfte med arbetet har varit att ta reda på vilken kategori av deltagare som kommer att klara av utvecklingen av ett informationssystem genom att använda sig av ett RAD-verktyg. Utifrån de observationen som genomfördes så var det bara användare på avancerad databaskunskaper som klarade av att lösa uppgiften. Övriga användare avbröt observationen på grund av olika anledningar.

Full textAbstract:
The topic of this master's thesis is a comparison of web Rapid Application Development frameworks Ruby on Rails and Spring Roo. The paper focuses on creating extensive overview of pros and cons of the subjected tools from the web developer's point of view to enhance his awareness about the subject, also to come up with new questions for further analysis or even convince him to use one of the frameworks in the real projects. Firstly, the paper contains a theoretical overview of the common conceptions for better understanding of the following parts and then specific principles for each of the selected frameworks. Secondly, there is a practical part. On one hand it demonstrates the implementation of a reference application using both platforms to illustrate the practical distinctions. On the other hand, it also contains an overall comparison based on the defined methodology. Altogether, it should form a comprehensive comparison of the selected frameworks for web developers interested in Ruby and Java platforms.

Full textAbstract:
An increasing amount of companies and organizations are starting to implement the use of cloud computing in their business. This trend results in that software, which was previously sold and distributed to the customers whom then had to install the software on their own computers, now is being replaced with Software as a Service (SaaS). SaaS makes software available through the customers’ browsers, which results in that the service providers only have to administer a single application. The process to migrate a distributed application to a service delivered as a SaaS lacks sufficient investigation; this paper will provide some guidelines for conducting such a pro- cess. During the work on this paper, a prototype of a service delivered as a SaaS has been devel- oped with the intention to test, among other things, how a distributed relational database can be converted to a key/value pair storage. A conversion of this kind enables data to be stored locally in the customers’ browsers, which relieves some pressure on the server as well as enables the application to be used in offline-mode. The paper results in three guidelines which should be considered when planning to migrate software to a service delivered as a SaaS with a local data- base; Think before you act, Don’t expose your soul and Size matters. These guidelines describe how a migration process should be planned, when an application is not deemed appropriate to migrate and when a conversion of the database is not appropriate.Allt fler företag och organisationer börjar implementera användandet av olika molntjänster i sin verksamhet. Den här trenden medför att programvaror, som tidigare sålts och distribuerats till kunder vilka sedan själva får installera dem på sina egna datorer, nu börjar ersättas med en Soft- ware as a Service (SaaS). Det innebär att programvaran istället finns tillgänglig på Internet via kundernas webbläsare, något som medför att tjänsteleverantören enbart behöver administrera en enda programvara. Processen att migrera en distribuerad programvara till en SaaS-tjänst saknar ordentlig utredning, det här arbetet syftar därför till att ta fram några vägledande riktlinjer för en sådan process. Under arbetets gång har en prototyp av en SaaS-tjänst utvecklats med syfte att testa bland annat hur en tidigare distribuerad relationsdatabas kan konverteras till nyckel/värde- par. En sådan konvertering möjliggör lokal lagring av data i kundernas webbläsare, vilket mins- kar belastningen på servern samt erbjuder möjligheten att arbeta offline. Arbetet resulterar i tre riktlinjer att beakta då en migration till en SaaS-tjänst med lokal databas planeras; Tänk efter, före, Blotta inte din själ och Storleken har betydelse. Riktlinjerna beskriver hur en migrations- process bör planeras, när en applikation inte anses lämplig att migrera samt när en konvertering av databasen inte anses lämplig.

Hernadez, Frank. "MobiMed: Framework for Rapid Application Development of Medical Mobile Apps." FIU Digital Commons, 2013. http://digitalcommons.fiu.edu/etd/957.
Full textAbstract:
In the medical field images obtained from high definition cameras and other medical imaging systems are an integral part of medical diagnosis. The analysis of these images are usually performed by the physicians who sometimes need to spend long hours reviewing the images before they are able to come up with a diagnosis and then decide on the course of action. In this dissertation we present a framework for a computer-aided analysis of medical imagery via the use of an expert system. While this problem has been discussed before, we will consider a system based on mobile devices.
Since the release of the iPhone on April 2003, the popularity of mobile devices has increased rapidly and our lives have become more reliant on them. This popularity and the ease of development of mobile applications has now made it possible to perform on these devices many of the image analyses that previously required a personal computer. All of this has opened the door to a whole new set of possibilities and freed the physicians from their reliance on their desktop machines.
The approach proposed in this dissertation aims to capitalize on these new found opportunities by providing a framework for analysis of medical images that physicians can utilize from their mobile devices thus remove their reliance on desktop computers. We also provide an expert system to aid in the analysis and advice on the selection of medical procedure. Finally, we also allow for other mobile applications to be developed by providing a generic mobile application development framework that allows for access of other applications into the mobile domain.
In this dissertation we outline our work leading towards development of the proposed methodology and the remaining work needed to find a solution to the problem. In order to make this difficult problem tractable, we divide the problem into three parts: the development user interface modeling language and tooling, the creation of a game development modeling language and tooling, and the development of a generic mobile application framework. In order to make this problem more manageable, we will narrow down the initial scope to the hair transplant, and glaucoma domains.

Published ArticleRP and recently RM have been key factors in the development of the manufacturing industry in assisting in the development of new products. Fortunately, the application of these technologies has been realised in the medical industry. Surgeons all over the world use physical models created from CT or MRI data using some sort of additive manufacturing. The fabrication of these models has exploded into a popular research area combining engineering, material and medical expertise. Long-term growth in the additive fabrication industry will come from designs that are difficult, time-consuming, costly, or impossible to produce using standard techniques. Growth will occur with advances in current additive processes which are coupled with breakthroughs in new materials. The applications of RP and RM are as diverse as the medical issues that arise. RM of custom design medical prostheses proves to be economically viable solution, not only because it is faster to produce but it gives the designer freedom of creation too. The paper discusses some interesting medical case studies.

Albrecht, Conan Carl. "Programming framework supporting the rapid application development of highly-interactive, collaborative applications." Diss., The University of Arizona, 2000. http://hdl.handle.net/10150/558708.
Full textAbstract:
Business team collaboration in the future will increasingly take place in an
environment where everything is potentially distributed. Traditional group support systems
have been LAN-based and have not ported easily to distributed, Internet-based products.
Rather, distributed group support systems require new architectures if they are to support the
same type of real-time, high-collaboration environments that traditional systems have.
This dissertation describes the development of a server architecture and programming
model to support the rapid application development of real-time, distributed, and
collaborative applications. Since the efficiency, robustness, and scalability of these
applications are handled by the server, complex applications can be developed in very short
production cycles.
Background literature presented in the dissertation includes a taxonomy of distributed
networking and data sharing methods, models of dialog independence, and messaging
methods. Many different prototype and real systems are presented, analyzed, and compared
with the Collaborative Server in this dissertation. The Systems Development methodology
is applied to this research domain.
A prototype system-the “Collaborative Server”-is developed, including a unique data
persistence and replication scheme based upon a central Property object. Properties are
created in hierarchical trees to form the “scaffolding” for collaborative applications. Each
Property governs a single value, or datum, and controls the access, replication, security,
viewing, locking, and persistence of its value. Properties are layered with predefined or
custom child indices.
A new systems development methodology, based upon the Waterfall method but
tailored for the Collaborative Server, is presented. The efficiency and effectiveness of this
methodology is analyzed using a simulated example and two case studies.
The research contribution of this dissertation is the Collaborative Server. The basis
of this server is the Property concept, including the methodology changes it effects, the
efficiencies and application stability it produces, and the specialized messaging system it
allows. Required programmer knowledge is significantly reduced when applications are built
upon the Collaborative Server. In addition, the presented examples and case studies show
significant decreases in code size and in time-to-market for their respective applications.

Full textAbstract:
In aircraft design, methods for rapid aerodata assessment and data screening at early stages are instrumentalin reducing development cost and first-time-right processes. New efficient tools for the analysis can easethe transition as the traditional and rigidly structured sequential design process gives way to a concurrentmulti-disciplinary process with the compressed time-span required in the competition for market shares. The CEASIOM-SUMO-EDGE software suite provides a way from initial sizing to stability and control design andassessment, including effects of aero-elasticity. CEASIOM ongoing and further development is driven by user needs, and the thesis reports on fourdifferent design and analysis cases which required enhancement of CEASIOM in several respects. The validation study on the B-747 with its multitude of control surfaces required generalizationof control surface definition and modeling. The clean-sheet design of the TransCruiser Mach 0.97passenger transport required compilation, fusion, and screening of aerodynamics data from many sourcesand in different formats. The DanBus and the asymmetrical twin-prop pusher-puller configuration required translationof geometry representation and development of simple propeller models in the automatic meshgeneration and CFD analysis. The way forward is provided by adoption of common data formats and geometry (and structural, etc.)modeling conventions. To this end the current proprietary XML format should be replaced by a more generalXML system such as CPACS under development at DLR which will be made public in the near future.QC 20110629

Full textAbstract:
Lignin is a major chemical component of plants and the second most abundant natural polymer after cellulose. The concerns and interests of agriculture and industry have stimulated the study of genes governing lignin content in plants in an effort to adapt plants to human purposes. Arabidopsis thaliana provides a convenient model for the study of the genes governing lignin content because of its short growth cycle, small plant size, and small completely sequenced genome. In order to identify the genes controlling lignin content in Arabidopsis accessions using Quantitative Trait Locus (QTL) analysis, a rapid micro-scale method of lignin determination is required.
The acetyl bromide method has been modified to enable the rapid micro-scale determination of lignin content in Arabidopsis. Modifications included the use of a micro-ball mill, adoption of a modified rapid method of extraction, use of an ice-bath to stabilize solutions and reduction in solution volumes. The modified method was shown to be accurate and precise with values in agreement with those determined by the conventional method. The extinction coefficient for Arabidopsis lignin, dissolved using acetyl bromide, was determined to be 23.35 g-iLcm-1. This value is independent of the Arabidopsis accession, environmental growth conditions and is insensitive to syringyl/guaiacyl ratio. The modified acetyl bromide method was shown to be well correlated with the 72% sulfuric acid method once the latter had been corrected for protein contamination and acid-soluble lignin content (R² = 0.988, P < 0.0001).
As determined by the newly developed acetyl bromide method and confirmed by the sulfuric acid method, lignin content in Arabidopsis was found to be a divergent property. Lignin content in Arabidopsis was found to be weekly correlated with growth rate among Arabidopsis accessions (R² = 0.48, P = 0.011). Lignin content was also found to be correlated with plant height among Arabidopsis accessions (R² = 0.491, P < 0.0001).

El control microbiològic és essencial en la indústria farmacèutica ja que es tracta d’un indicador de la seguretat dels productes. Els mètodes microbiològics utilitzats a les companyies farmacèutiques per analitzar l’ambient del procés de fabricació així com els productes finals estan basats en mètodes de cultiu tradicional. La tecnologia d’aquests mètodes manca de precisió comparada amb les tecnologies més modernes de detecció i identificació microbiològica.
Cada vegada, els requeriments dels controls microbiològics de productes i processos són més estrictes, el que fa que es necessiten mètodes cada vegada més ràpids i precisos. Dintre d’aquest context s’han desenvolupat els mètodes de microbiologia ràpida (RMM) per a la seva implantació a la industria farmacèutica, avalada per les diferents agències reguladores. Les diferents tecnologies en les quals es basen els RMM es coneixen a l’àmbit acadèmic des de fa dècades, no obstant la seva implantació i validació a les indústries farmacèutiques és relativament recent.
La implementació de noves metodologies a l’àmbit farmacèutic està regulada per la normativa de bones practiques de fabricació (BPF), el qual va associat a una adequada validació de les tècniques. Aquesta tesi descriu la implementació de RMM al control microbiològic del procés de fabricació i productes a l’empresa Laboratoris Reig Jofré (RJF). El principal objectiu ha estat dividit en 3 blocs individuals: implementació d’un programa d’identificació microbiana per als aïllats del procés de fabricació i productes; implementació d’un mètode de detecció de microorganismes a l’aire de sales classificades per fabricació asèptica basat en fluorescència induïda per làser i l’ avaluació d’un sistema basat en citometria en fase sòlida per la detecció de microorganismes en productes filtrables.
En general, els RMM implementats han contribuit a obtenir resultats de manera més ràpida, el qual permet mitigar el risc de contaminació en el mateix moment que ha sigut detectat. Aquest projecte assenta les bases per futures aplicacions de RMM en el procés de fabricació farmacèutica.Microbiological testing plays an essential role in the Pharmaceutical Industry as it is an indicator of safety in drug products. The microbiological methods used in the pharmaceutical companies for testing the environment of the manufacturing process as well as the final products are based on traditional culture methods. These methods, although being appropriate for their intended use, rely on century-old technology that lacks accuracy when compared to most up-to-date methodologies for microbial detection and identification. Every time the requirement of microbiological testing of products and processes increases, arising the need of faster and more accurate methods. In this paradigm, rapid microbiological methods (RMM) are developed for their implementation in the pharmaceutical industry encouraged by regulatory agencies. The different technologies in which rapid microbiological methods are based have been known in the academic field for decades, however their implementation and validation in the pharmaceutical industries is relatively recent. Implementation of new methodologies in a pharmaceutical environment ruled under Good Manufacturing Practice (GMP) guidelines needs proper validation of the techniques involved. This thesis describes the implementation of RMM in the microbial monitoring of the pharmaceutical manufacturing process and products in Reig Jofré Laboratories (RJF). The main objective has been divided into three different blocks: implementation of a microbial identification program for the isolates found in the production process and products; implementation of a laser-induced fluorescence system for the detection of airborne microorganisms in cleanrooms for aseptic processing and evaluation of a solid-phase cytometry system for the detection of microorganisms in filterable products. In general, the RMM implemented have contributed to obtain faster results which allows to mitigate contamination risk at the moment it is detected. This projects lays the ground for further applications of RMM in the pharmaceutical manufacturing process.

Full textAbstract:
Whole cell biosensors have been extensively used for monitoring toxicity and contamination of compounds in environmental biology and microbial ecology. However, their application in the pharmaceutical and cosmetics industries for preservative efficacy testing (PET) has been limited. According to several pharmacopoeias, preservatives should be tested for microbial activity using traditional viable count techniques; the use of whole cell microbial biosensors potentially provides an alternative, fast, and efficient method. The aim of the study was to construct and develop whole cell microbial biosensors with Pseudomonas aeruginosa ATCC 9027. Constitutive promoters: PlysS, Pspc, Ptat, Plpp and PldcC and the lux-cassette were inserted into plasmid pME4510 and transformed into P. aeruginosa ATCC 9027 cells to produce bioluminescent strains. Plasmids were found to be maintained stably (~50 copies per cell) throughout the growth and death cycle. The novel bioluminescent strains were validated in accordance with the pharmacopoeia using bioluminescence detection and quantification followed by comparison with the traditional plate counting method. The bioluminescent method was found to be accurate, precise and equivalent at a range of 103 – 107 CFU/mL, as compared with plate counting. Recovery of bacterial cells was quantified using bioluminescence; this method proved to be accurate with percentage recoveries between 70-130% for all bioluminescent strains. The method was also more precise (relative standard deviation less than 15%) than the traditional plate counting method or the ATP bioluminescent method. Therefore, the bioluminescent constructs passed/exceeded pharmacopoeial specified criteria for range, limit of detection, accuracy, precision and equivalence. Physiology of the validated bioluminescent strains was studied by assessing the growth and death patterns using constitutive gene expression linked with bacterial replication. Promoter strengths were evaluated at various stages of the growth and death pattern and related to promoter sequences. PlysS, Ptat and Plpp were relatively strong promoters whilst PldcC and Pspc were relatively weak promoters. Relative promoter strength decreased in the order of Plpp>Ptat>PlysS>PldcC>Pspc during the exponential phase whilst Ptat was stronger than Plpp during the stationary phase of growth. Plpp had its highest level of expression during the exponential phase, while Ptat had relatively stable lux expression during the stationary phase. Correlations between relative bioluminescence and CFU at 24 hours were greater than 0.9 indicating a strong relationship for all bioluminescent strains. Reduction in correlation coefficients to approximately 0.6 between relative bioluminescence and CFU and between relative fluorescence and CFU beyond 24 hours indicated that a certain proportion of cells were viable but non-culturable. Tat-pME-lux showed steady bioluminescence compared to CFU count (R>0.9) throughout 28 days of growth. Equivalence analysis showed no significant difference between the bioluminescence and plate count method throughout 28 days of growth for all five bioluminescent strains. Applicability of these novel bioluminescent strains was evaluated for preservative efficacy tests (PET) using bacterial replication and bioluminescence as a measure of constitutive gene expression. PET using benzalkonium chloride and benzyl alcohol showed no significant difference between the bioluminescent method and the plate count method. Good correlations between bioluminescence, CFU count and fluorescence were obtained for benzalkonium chloride (BKC) concentrations (R>0.9) between 0.0003% and 0.0025% against strains lysR25, lppR4 and tatH5. Similarly, good correlations (R>0.9) between the three parameters were obtained for benzyl alcohol (BA) concentrations between 0.125% and 2% against strains lysR25, lppR4 and tatH5. The bioluminescent method and traditional plate counting method were equivalent for concentrations of BKC (0.0003 - 0.02%) and BA (0.25 - 2%) during preservative efficacy tests. These bioluminescent constructs therefore are good candidates for selection for preservative efficacy testing. The bioluminescent method and traditional plate counting method were also found to be equivalent for construct tatH5 at a concentration of 0.125% BA. PET testing with BKC and BA showed that tatH5-pMElux (R>0.9) had consistently high correlation coefficients between CFU and relative bioluminescence. Together with the results from growth and death kinetics, where tatH5 showed the greatest constitutive expression, it can be concluded that P. aeruginosa ATCC 9027 tatH5-pMElux is the best construct for testing various antimicrobial agents. This study has shown that according to the pharmacopoeial requirements, the bioluminescent method is more accurate, precise and equivalent to the traditional plate counting method and therefore can be utilised instead of the traditional plate counting method for the purpose of preservative efficacy testing.

Le point de départ de cette thèse a pour origine les difficultés constatées dans la communauté EIAH pour concevoir des applications éducatives exploitant des informations géographiques. A terme, il s'agit de proposer une nouvelle plateforme susceptible de rendre possible et opérationnel la conception d'applications Web géographiques portées par des utilisateurs non-informaticiens de façon autonome. La proposition scientifique est basée sur un processus de conception piloté par les contenus et par les interactions. Il est opérationnalisé dans une plateforme nommée WINDMash offrant aux concepteurs un environnement visuel de spécification et d'évaluation des interactions. Nous proposons un modèle unifié sous-jacent de description des applications Web géographiques comportant trois facettes qui permettent de représenter les contenus géographiques manipulés, de les afficher sur une interface graphique et de décrire le comportement de l’application (scénario d’interaction) à l'aide d'un langage visuel dont le formalisme graphique est inspiré du diagramme de séquence UML. En utilisant des techniques d'Ingénierie Dirigée par les Modèles, la plateforme WINDMash permet de générer automatiquement le code de l'application finale sur la base des instances de trois facettes du modèle unifié. La plateforme WINDMash utilise pour cela l’API WIND (Web INteraction Design) que nous avons programmée. Les concepteurs peuvent ainsi prototyper rapidement des applications Web géographiques correspondant à leurs besoinsThe starting point of this thesis is to deal with the difficulties encountered in the TEL community for designing educational applications exploiting geographic information. Ultimately, it is to provide a new framework allowing for the operational design of geographic Web applications for experts in the domain (and particularly for teachers). The scientific proposal is based on a design process driven by contents and interaction. It is operationalized on a framework called WINDMash offering designers a visual environment for simply specifying and immediately evaluating interactions. The unified model for describing geographic Web applications has three parts: one for representing geographic contents, one for displaying them on a graphical user interface (GUI) and one for describing the behaviour of the application using a visual language whose graphical formalism is based on the UML diagram sequence. Using Model-Driven Engineering (MDE) techniques, the WINDMash framework can automatically generate the code of the final application based on the instances of three parts of the unified model. The WINDMash framework used for this the WIND API (Web INteraction Design) that we programmed. Designers can thus rapidly prototype geographic Web applications corresponding to their needs

L’objectif de ce travail a été de développer deux approches analytiques dédiées à l’analyse toxicologique des nouveaux produits de synthèse (NPS) dans différentes matrices biologiques (sang, urine et cheveux). La première est basée sur le criblage non ciblé par chimiluminescence sur biopuces et chromatographie liquide couplée à la spectrométrie de masse haute résolution (LC-HRMS) et la deuxième correspond à un criblage ciblé par spectrométrie de masse en tandem (LC-MS/MS). Ces deux approches ont ensuite été appliquées dans des études observationnelles pour évaluer la consommation de NPS dans des populations à risques de surdosage, de pharmacodépendance ou de soumission chimique dans un contexte clinique ou médico-judiciaire.La dernière partie a été consacrée au développement d’un nouvel outil analytique de traitement des données issues de la LC-HRMS qui a permis d’étudier le métabolisme de 9 NPS in vitro sur des cultures de microsomes du foie humain (HLM) et in vivo sur des échantillons biologiques d’usagers de ces drogues. Cette dernière approche a permis la création d’une bibliothèque de spectres de haute résolution composée de 228 métabolites dont certains ont été proposés comme marqueurs pertinents d’exposition aux NPS dont ils sont issus.Ce travail a été concrétisé par la rédaction de 10 publications scientifiques et a permis d’initier plusieurs collaborations pluridisciplinairesThe aim of the present work was to develop two analytical approaches dedicated to the analysis of new psychoactive substances in different biological matrices (blood, urine and hair). The first approach is based on untargeted screening by both biochip array technology chemiluminescence assay and liquid chromatography coupled to high resolution mass spectrometry (LC-HRMS) and the second corresponds to a targeted screening by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). These two approaches were then applied in observational studies to assess the consumption of NPS in high risk populations (overdose, drug abuse, drug facilitated crimes) in clinical and forensic settings. The last part of the work was devoted to the development of a new analytical tool for LC-HRMS data processing which made it possible to study the metabolism of 9 NPS In vitro on human liver microsomes (HLM) and In vivo in biological samples from drug users. This approach has enabled the creation of HRMS spectral library containing 228 metabolites, some of which have been proposed as relevant markers of NPS exposure.This work has resulted on 10 scientific publications and allowed to initiate many multidisciplinary collaborations

Häufig wird für kommerzielle oder wissenschaftliche Zwecke Individualsoftware benötigt. Obwohl Anwendungen häufig denselben Mustern folgen, müssen oft auch triviale Bestandteile immer wieder neu entwickelt werden, zudem erfordert die Entwicklung allgemein entsprechende Fachkenntnisse. Daher besteht die Idee Plattformen zu entwickeln, die keine oder wenig Programmierung erfordern und somit die einfache und schnelle Entwicklung von Anwendungen unterstützen, um Zeit und Kosten zu sparen. Das W3C hat für verteilte Dienste Standards für die Beschreibung von Diensten, Prozessen und auch die Präsentation etabliert. Es ist Ziel dieser Arbeit diese Standards zu kombinieren und ein kompatibles, jedoch vereinfachtes Beschreibungsformat zu entwickeln, einschließlich einem Werkzeugkasten für die Codegenerierung und Bereitstellung einer Laufzeitumgebung. Durch Modularisierung soll die Plattform einfach erweiterbar bleiben.

In the modern era where technology is constantly evolving, it is important to evaluate new technological tools and approaches in order to gauge their potential for adoption. Rapid Application Development (RAD) has highly evolved over the years, but it has not seen much response at the university level. Several studies show that perceptions of usability form the basis of acceptance or rejection of new tools and applications. Thus, running a usability study on a specific RAD tool coupled with autoethnographic documentation of specific development experience with that tool has the potential to encourage university faculty/staff to consider teaching/using it.
This research study seeks to understand developers' perceptions regarding the usability aspect of Mendix, a Rapid Application Development (RAD) tool. Both qualitative and quantitative approaches were employed to discover and understand the extent of perceived usefulness, ease of use and satisfaction with the tool. The results of the study presented a case for academicians on the viability of teaching RAD or using Mendix for their web application development needs. The study ultimately sought to help university faculty understand what to expect while teaching RAD to students from computing background and also help them decide if they would like to use tools like Mendix for their software development projects or continue to use specific coding languages (traditional software development) for software development projects.

The major research field of this research is making the mold of aspherical lens with the rapid tooling (RT) technology and the research and development of the green RT making technology and the technology of silica in complex and large geometrical form. This paper first makes the mold of aspherical lens with silica and assesses its feasibility. Then the research introduces the green manufacturing (GM) technology into RP technology to reduce the manufacturing cost without affecting the surface accuracy of the mold. Finally, GM technology is applied to the development of the silica in complex and large geometrical form to maximize its effectiveness. Furthermore, the paper also proposes the technology used for manufacturing the silica in complex and large geometrical form to be used as know-how in the future. Finally, this research integrates GM technology and RT technology to manufacture the mold of aspherical lens. Thereinto, because the silica is soft, it is used to manufacture the intermediary mold, which will be used to research and manufacture the finally required mold of aspherical lens of aluminum-epoxy. Inject the molding aspherical lens copy with the mold and get the error value through non-contact measurement, and feed it back to the radius of curvature of the prototype. At last, the feedback data will be used to manufacture the second mold of aspherical lens of aluminum-epoxy; observe its compensation. It can be known from the research result that for applying the RT technology to manufacture the mold of aspherical lens, the surface roughness and the surface curvature are both within the allowed values and developing the mold with GM technology and RT technology can really reduce the costs effectively. Therefore, manufacturing the mold with GM technology and RT technology is feasible.

The key to survival in the modern manufacturing industry is to shorten product development period and reduce cost in order to quickly push diversified products to the market and seize opportunities. As a result, the rapid tooling (RT) technology has been developed. In this study the RT technology has been utilized to make the mold of Fresnel lens, where the silicone is used as the intermediate mold, and the epoxy resin is used to make hot embossing mold. However, the traditional RT mold is made of epoxy resin with a rather high cost. Therefore, for cost saving and enhancement of geometry accuracy, in this study the hybrid mold technology has been proposed based on the integration of RT mold and backing material. The results of this study have indicated a transcription rate of 97.12% of hot embossing mold of Fresnel lens made by RT technology, while the surface roughness of the hot embossing finished product is 8.95% higher than the prototype. The hybrid mold technology developed based on the integration with backing material has led to 78.77% of cost reduction and a 77.77% improvement on geometry accuracy. The residual stress of hot embossing is lower than injection molding, and the surface energy is only 29.1 mN/m, which is very suitable for stripping. Therefore, the hybrid mold technology proposed in this study has led to the advantages of simple fabrication method, low fabrication cost, low residual stress, high geometry accuracy and superior dimension accuracy.

The development of refrigeration engineering not only stores up food but also develops and manufacture specific features on demand. Thus, this thesis proposes a kind of development and application of rapid refrigeration technology for ice coffee.The temperature controller is designed based on upper and lower limits of the temperature for ice coffee and used to perform experiments by using different amounts of refrigerant (142g, 127g, 112g, 97g) in the specific refrigeration machine. Our research focuses on the evaluation of the design to the temperature range and switch control with fixed amount of refrigerant, and investigates the influence of different amount of refrigeration to the refrigerant system. We propose our methodology and collect the best results of 6℃ and 9℃ controllers, respectively with different amount of refrigerant. We then perform cross-comparison with these two results. Our research keeps the arrival time to reach the refrigeration temperature, maintenance cost, the above-freezing evaporation barrel, and equipment life in mind. We conclude that the design of 6℃ controller and 112g of refrigerant has the best performance for rapid refrigeration technology for ice coffee.

Nowadays, due to the increasing amount of multimedia content and the growing demand for rich-media presentations, this creates a need to build tools that enable everyday people to develop multimedia applications by themselves. Moreover, people would like to create personalized applications to realize their distinctive ideas. Although many emerging standards (such as MPEG-4) and media formats (such as QuickTime, Flash, etc.) are made to meet this demand, there is not a flexible and programmable framework to bridge the gap in the development process between traditional applications and multimedia applications. Even for an experienced developer, developing a multimedia application remains difficult. Thus, we consider the research challenge to find a methodology for rapid and ease-of-use development of multimedia applications. In this thesis, we propose a design and implementation of a RApid Multimedia Application Development (RAMAD) system. The design considerations are as follows: 1.In order to deal with complex multimedia content, we adopt MPEG-4 as a core component for presentation. 2.In order to reuse conventional Graphic User Interface (GUI) in RAMAD system, we include existing GUI components and make them interactive with the MPEG-4 component. 3.In order to facilitate the development process, we use a scripting language, i.e. Python, to glue all Python extension components. Python has some good features for debugging and testing during developing stage, such as interpreting and dynamic binding. 4.In order to deploy RAMMAD system on different platforms, we develop most components in a cross-platform manner, such as GUI and MPEG-4. This makes RAMAD application portable while migrating to other platform. With RAMAD system, users can rapidly build a proof-of-concept prototype of a target multimedia application, and show the significant idea to other people. Furthermore, they can refine the proof-of-concept prototype to be a full-blown multimedia application, which is portable to different platforms.

Since metallic-resin rapid tooling has poor thermal conductivity, the product made with such mold tends to have longer molding cycle comparing with that made with conventional steel mold. To overcome this challenge, a novel wax-injection mold with cooling channels of complicated geometry was designed in this study by integrating 3D printing and rapid tooling technologies. During the fabrication of rapid tooling, cooling channel supporting model was included. In the end, acetone was used to remove the cooling channel supporting model, forming a wax-injection mold with conformal cooling channels. After evaluating the feasibility of experiments which will be carried out in this study, molds with different cooling designs will be fabricated to verify their practical applications. In this study, four low-pressure, wax-injection silicon molds, namely no-cooling mold, traditional cooling mold, parallel-connected conformal cooling mold and serial-connected conformal cooling mold, will be fabricated and wax-injection temperature experiments will be carried out for these four types of molds.From the experimental results, it is found that the time to reach mold-opening temperature is 150 minutes for no-cooling mold, 54 minutes for traditional cooling mold, 21 minutes for parallel-connected conformal cooling mold and 14 minutes for serial-connected conformal cooling mold.If no-cooling mold is used as the base to compare the cooling efficiency of various molds with different cooling designs, the operation time saved is 63% for traditional cooling mold, 86% for parallel-connected conformal cooling mold and 91% for serial-connected conformal cooling mold. The above result suggests that conformal cooling design produces better cooling efficiency than traditional cooling design, while serial-connected conformal cooling mold gives better cooling efficiency than parallel-connected conformal cooling mold.

This paper presents a new Rapid prototyping system by using a DLP (Digital Light Processor) as light source. The PC-based controller generates the layer patterns by giving the CAD model (STL file) of the work piece to be made. This DLP light source can directly solidify the photosensitive resin layer by layer without LCD mask. In this research, the output property of a DLP light source is analyzed. Firstly, a photosensitive diode mounted in a 3-Axis machine is used to measure the intensity distribution of a DLP output. The characteristic of a photosensitive resin is also investigated by exposing it with DLP light. It is showed that the intensity distribution of a DLP is better than a traditional projector. The better gray degree performance and high contrast of the DLP can shorten the curing time of a photosensitive resin. From the experimental results, the curing efficiency of the DLP-based RP machine is much better than LCD-based RP machine due to its direct illumination. It can save the curing time even more than 50% without losing the contour of a work piece. The curing resolution can reach up to 0.1mm per pixel. It takes almost 3 hours for building a aligned teeth model. It will improve the application of a mask-based RP system.

Owing to the advances in internet and transportation, enterprises have been deeply affected by the impact of same type companies from all over the world. How to survive in such an ordeal has become the most important issue for all enterprises. Against such a background, rapid tooling technology has gradually become a common manufacturing method. As the product life cycle getting shorter, a small batch production of flexible products has been gradually discussed. Therefore, vacuum casting technology was proposed. The traditional vacuum casting technology fills the mold cavity up with material only by gravity, and the yield rate of the complicated geometric shape and the thin shell products is low. The product of traditional vacuum casting technology frequently have several defects such as micro-bubbles, voids, weld lines, shrink mark, or short shot. Therefore, this study used differential pressure vacuum casting technology to fabricate components with microstructures. Fresnel lens was used as a microstructure prototype. The results of the study found that differential pressure vacuum casting technology can improve the defects of vacuum casting products obviously. The transcription rate of micro-featured components manufactured by the vacuum casting process was increased from a minimum of 36.3% to a maximum of 98.3%. In addition, this study also used the Bernoulli’s equation and the equation of continuity to propose the theory of the differential pressure effect. Furthermore, in order to propose the filling mechanism of the vacuum casting machine, this study developed the horizontal and vertical research models. The mold flow analysis software Moldex3D was used to simulate the material filling process. The research models were manufactured by 3D printing technology, and the silicone rubber mold was made for vacuum casting. Thus, this study proposes a filling mechanism for vacuum casting in horizontal and vertical directions.

There has been an increasing need of micro-sized features mold in recent years. It is being applied in many fields, such as Microactuator, Micro Drivetrain System, and Communication System. Based on the premise that transcription rate was expected to rise, the current study manufacturd micro gear Al-filled epoxy hot embossing molds by means of Rapid Tooling (RT) where the rubber is used as intermediate mold. In addition, high aspect ratio micro sized features are widely applied.To manufacture molds with high aspect ratio micro sized features, the current study proposed an ideal skill for manufacturing Al-filled epoxy of high aspect ratio close to 20 by which applying oxygen plasma treatment to surface modification and the rubber is used as intermediate mold. Made with high aspect ratio micro sized features mold, such hard molds require only three working days to meed the need of mass production of parts. The study of micro gear Al-filled epoxy hot embossing molds showed that replication rate of manufacturing micro mold was 96%, the surface roughness was 1.98 μm. Replication rate of application to micro hot embossing process was 99.2%, and that the replication rate of comparing master models was 94.5%. The study of molds with high aspect ratio micro sized features showed the total replication rate was 98.4%. In comparison with Micro Electro Mechanical Systems (MEMS), the cost of development was cheaper by 71.3 %. Therefore, the skill proposed in the study successfully sped up manufacturing process and increase accuracy.

Cylindrospermopsin (CYN) is a toxic secondary metabolite produced by Cyanobacteria in water body. Because of its stable structure and high solubility in water, CYN is not easy to remove by conventional drinking water treatment processes, resulting in negative effect on human health. CYN has been discovered in a few of Taiwan’s reservoirs, including in main island and in Kinmen island. Therefore, a method to accurately and rapidly estimate the risk associated with the presence of CYN in drinking water sources in required for the protection of public health. Therefore, in this study we proposed to establish an on-site monitoring technology for Cylindrospermopsis cells and CYN-producing cells using qPCR combined with TaqMan system. Both single and dual quantification systems targeted for the functional genes of Cylindrospermopsis cells, rpoC1, and CYN producing cells, pks, using qPCR combined with TaqMan system were successfully established. The qPCR-TaqMan method was further applied in the on-site monitoring of the targeted genes present in Taiwan’s reservoirs. A total of 73 and 60 samples were collected and analyzed for 11 reservoirs in main island and 11 reservoirs and 2 drinking-water treatment systems in Kingmen island, respectively. During the monitoring, an enzyme-linked immunosorbent assay (ELISA) and an optical microscope were also employed to analyze the concentrations of CYN and Cylindrospermopsis cells, respectively. Monitoring results showed that good correlations between rpoC1 gene copy numbers detected with the qPCR method and cell numbers enumerated with optical microscope. For another targeted gene, pks, although no correlations were obtained, 90% of the Kinmen samples showed co-occurrence of pks gene copies and CYN concentrations measured with ELISA. A dual quantification system for both pks and rpoC1 genes was also developed. The experimental parameters were tuned to improve the detection of both genes, serving as a basis to better apply the dual detection system in the future.

In recent years, urban flooding caused by heavy intensity rainfalls has occurred more frequently, since the frequency of extreme rainfall events is increasing. The loss of life and properties could be effectively reduced by urban flooding simulation, which provides reference for flood and disaster prevention. Nowadays, the urban flood inundation models have gradually matured. Most of them couple the one-dimensional (1D) sewer flow model (SFM) and the two-dimensional (2D) overland flow model (OFM) to simulate dynamic flow interactions between storm sewers and overland surface. They can reasonably simulate the flooding of urban areas. However, urban flood inundation model nowadays is often used for pre-simulating instead of real-time forecasting due to long simulation time for two-dimensional overland model. In this study, we first utilize the concept of cellular automata to propose a two-dimensional rapid overland flow model with a simple water transition rule instead of solving the momentum equation. The proposed two-dimensional rapid overland flow model is then coupled with the one-dimensional (1D) sewer flow model to simulate the dynamic flow interactions between storm sewers and overland surface, and thus constructing our rapid urban flood inundation model. As for urban flood inundation model that solves the shallow water equations is herein called the traditional urban flood inundation model. In this study, the Muzha sub-catchment area of Wenshan District, Taipei City is selected as the research area. Two short duration heavy intensity rainfall events are used to compare the proposed rapid urban flood inundation model and the traditional urban flood inundation model. The comparison results show that the proposed model can provide considerably good simulated results to those of the traditional model. Besides, the simulation time of the proposed model is only 15% of the traditional model. It is evident that the proposed model can be a useful alternative of the traditional model.

At present, mainstream AI technology mostly relies on high-performance computer hosts, and embedded systems running on microcontrollers are rare. If the mature AI technology can be run on the microcontroller, you can not only let AI technology be applied in more fields, but also bring considerable power saving in many applications. In this research, the virtual machine was added to enable the microcontroller to be flexibly deployed, so that the deep neural network application implemented in the microcontroller can be deployed in a more convenient manner. After making up for the gap in the convenience of the deep neural network between the microcontroller and the host computer, the aforementioned goals will become feasible. The subsequent experiments also verified the function of the virtual machine and the correctness of the implemented neural network. This research preserves the advantages of the microcontroller and overcomes its shortcomings while bringing deep neural network applications into the microcontroller-based embedded system. Compared with high-energy and high-cost hosts, the extremely low power consumption system of this research will bring considerable energy savings.

Abstract Utilize the tissue engineer to make artificial knee joint, Must finish the scaffold of three kinds of joint structure components , such as femur , shin bone and meniscus,the traditional method of making tissue scaffold is through molding（solvent casting/ emulsion freeze drying/ gas foaming）. Can't control the question of linking with hole of the hole structure of the scaffold (the size , density ). The femurs , shin bones are that the hard bone tissue has complicated appearance of geometry, can't do with the mold . While studying by Jessica M. Williamsa , utilize the laser sintering process scaffold have good mechanical intensity, do not need the support frame, so can solve the problem of the complicated appearance of geometry . In addition, the meniscus is organized by the cartilage, make with mould shaping law , will use organic solvent dissolve the packing material (sodium chloride ) out , will cause and bind the question such as being bad each other among Kong Dong's all kinds of inequality and hole. It will influence cells to grow on the scaffold that the solvent remains. Incomplete shortcoming that the laser sintering process will produce the hot stress centralizedly and frit. So, utilize laser sintering make the artificial hard bone support of knee joint and cartilage support. Except that this, will do the two phase compounding type scaffold that the soft hard bone cell turns into in experiment. Can let the Cartilage tissue , hard bone tissue cells to grow and open time , will have cartilages to organize the scaffold covered to make the human skeleton structure. This research is divided into softly / hardware two partly, Have already developed and organized the optimization unit structure software design of the support in the part of the software, technology of planning etc. that organize support mechanics and analyse software design , single layer and cut story , single story in the route totally totally .

Tissue engineering is a combination of material science and bioscience. The main aim of tissue engineering is to grow tissue or organs externally outside the body is to overcome current problems of organ transplant like organ shortage, organ rejection, have to take drugs for long periods to suppress organ rejection, high risk of infection, etc. Tissue engineering must comprise of 3 important elements; scaffold, cell and signal. The purpose of this research is to study the technical difficulties related to the fabrication of tissue scaffold. In order to grow the tissue scaffold, we need to first fabricate a tissue scaffold of the same shape. Hence, the success of the tissue scaffold fabrication will determine the success of the tissue scaffold fabrication. When designing the tissue scaffold, we need to consider factors such as pore diameter, pore density and structural strength. According to research done by ITRI (Industrial Technology Research Institute), if the design of the tissue scaffold is not good, it will result in poor formation of the tissue scaffold. This in turn will result in the poor adhesion of the cells during initial formation stage. The resulting implant will face problems related to structural strength. In addition, the traditional method of making tissue scaffold is through molding. This process involves the use of chemicals to carve out the pores. However, if there is residue remaining in the pores of the mold, it would lack biocompatibility. Moreover, another disadvantage of using the traditional molding method is that there is a limit to structural complexity. In order to overcome the shortcomings of the traditional molding method, this research proposes a new method of using laser sintering to make tissue scaffold. The scope of this research includes the hardware design of the “laser sintering rapid prototyping” machine, computer aided design (CAD) file slicing and laser sintering profile path programming. Lastly, this research will also use the “laser sintering rapid prototyping” machine to test out its feasibility. This research comprises of 3 different stages. First stage is the hardware design of the “laser sintering rapid prototyping” machine. The hardware design includes capability study and design guidelines for this machine. Using Solidworks for function design, platform for tissue scaffold fabricator, CO2 laser module and air pressure-damper module design, control of the circuit using Galil motion control card. Second stage is the design of CAD file slicing interface , laser sintering profile path programming interface and human-machine interface software design. This would involve using CopyCAD and Visual Basic to design the software window platform for CAD file slicing, using PowerMill and Visual Basic to design the software window platform for laser sintering profile path programming and using Visual Basic to design the human-machine interface software window platform. Third stage is to combine the “laser sintering rapid prototyping” machine with CAD file slicing module and laser sintering profile path programming to build the physical system. This includes the testing of both hardware and software of the machine. Lastly, to test the system by building actual tissue scaffolds. This research uses “copolymer bone cement” to successfully build 6 different types of tissue scaffolds; 0/90 deg, 30/60 deg, 45/135 deg, 0/90 deg hexagonal shape, 45/135 deg circular shape and 0/90 deg triangular shape. This proves that the “laser sintering rapid prototyping” system can be used to test out more shapes and structural designs of the tissue scaffold by changing the pore diameter and pore density. The “laser sintering rapid prototyping” system in this research combines CAD file slicing and laser sintering profile path programming techniques to produce that is capable of using 2-D layer slicing and controlling different filament gap or pore shape, the “laser sintering rapid prototyping” machine can make different pore diameters and pore density. This machine proves that this creative technique is feasible for rapid prototyping for tissue scaffolds. Hence, paving the way for new scaffold designs and fabrication methods.
