No. of bitstreams: 1 3769.pdf: 7885518 bytes, checksum: 7723f0868651af930744610d4adb9ccb (MD5) Previous issue date: 2011-05-30 / Financiadora de Estudos e Projetos / Embedded systems have been used in a myriad of devices that are present in our daily lives, thereby the market for such sort of system has increased significantly over the last few years. These systems were once associated with low-level code, however, this is an outdated view of embedded systems technology. Although the current embedded systems are mostly composed of software, no systematic reuse technique is used in throughout their development. Thus, since previous successful experiences are not reused, forcing the developer to create some of the involved elements from the scratch, there is a considerable delay in the production of these systems. Due to the ever increasing complexity of embedded systems it is necessary to apply reuse techniques in order to lessen the effort needed to develop such systems. Within this context, software product lines (SPL) are reuse techniques that allow the creation of several systems belonging to a certain domain. SPL can be used to generate products of a specific domain that share common features but are each different in a specific way. Model-driven development is another reuse technique whose main objective is to reduce the semantic distance between the domain problem and its solution/implementation; thus, the developer does not need to direct interact with the solution source code, being able to focus on models and transforming those models in source code or yet other models. Based on these techniques, a process for the development of SPL in the domain of mobile robots was developed. In order to properly use the proposed process, a SPL called LegoMobileRobots Software Product Line (LMRSPL) was devised. Moreover, a domain specific language (DSL) was also developed. This DSL, called F2MoC, assists the application engineer in instantiating LMRSPL members. / Sistemas embarcados são utilizados em vários dispositivos que fazem parte da vida cotidiana, de modo que o mercado de tais sistemas tem crescido de maneira expressiva. Esses sistemas sempre foram associados com código de baixo nível, no entanto, essa visão está desatualizada. Nas aplicações embarcadas correntes o software é a principal parcela, embora nenhuma técnica sistemática de reuso seja utilizada para sua concepção. Desse modo ocorre um atraso considerável na produtividade dos sistemas, uma vez que experiências anteriores bem sucedidas não são reaproveitadas, sendo necessário que o desenvolvedor comece do zero toda vez que um software for desenvolvido. Com a crescente complexidade dos sistemas embarcados é necessário utilizar técnicas de reuso para diminuir o atrasado da produção de tais sistemas. Nesse contexto, Linha de Produtos de Software (LPS) é definida como uma técnica de reuso que permite a construção de vários sistemas pertencentes a um mesmo domínio. LPS é aplicável para a geração de produtos específicos de um domínio, mas que possuem um conjunto de características comuns e pontos de variabilidades bem definidos. O Desenvolvimento de Software Orientado a Modelos (do inglês Model-Driven Development - MDD) é outra técnica de reuso na qual tem como principal objetivo reduzir a distância semântica entre o problema do domínio e solução/implementação, fazendo com que o engenheiro não precise interagir diretamente como o código-fonte, podendo se concentrar em modelos que possuem maiores níveis de abstração e posteriormente realizar transformações Model-To-Code e/ou Model-To-Model. A partir dessas técnicas de reuso é introduzido um processo para o desenvolvimento de linhas de produtos de software no domínio de Robôs Moveis. A fim de utilizar o processo proposto foi desenvolvida uma LPS intitulada LegoRobosMoveis Linha de Produtos de Software (LRMLPS). Adicionalmente, foi desenvolvida uma linguagem especifica de domínio denominada F2MoC que auxilia o engenheiro de aplicação na instanciação automática de membros da LRMLPS.

RestMDD: Ambiente colaborativo para o apoio no desenvolvimento de serviços Web RESTful / RestMDD: collaborative environment to support the development of RESTful web services

Robson Vinicius Vieira Sanchez 02 September 2013 (has links)
Na ultima década o paradigma de computação orientada a serviços (SOC - Service Oriented Computing) tem ganhado cada vez mais espaço na indústria e na academia, a fim de solucionar o problema da falta de comunicação entre os diversos sistemas de informação presentes dentro de um ambiente corporativo. Graças aos recentes avanços da chamada \"Web 2.0\" um novo estilo arquitetural chamado de Arquitetura orientada a Web (WOA - Web Oriented Architecture) foi proposto a fim de garantir uma maneira simples de conectar os componentes de software dinamicamente. Esse estilo tem como um dos princípios o uso de serviços Web RESTful, a fim de conseguir uma interface funcional simples e uniforme. Este trabalho apresenta um ambiente colaborativo de apoio ao desenvolvimento de serviços Web RESTful utilizando o paradigma de desenvolvimento orientado a modelos (MDD - Model Driven Development). Pretende-se mostrar os benefícios do MDD aplicado a Engenharia Web e também as vantagens apresentadas pela colaboração nesse cenário. Foi realizado ainda um experimento a fim de comprovar a eficiência do ambiente colaborativo e benefícios alcançados por ele / In the last decade the paradigm of Service Oriented Computing has gained more attention in industry and academia in order to solve the problem of lack of communication between different information systems present within a corporate environment. Due to recent advances in Web 2.0 a new architectural style called Web Oriented Architecture is proposed to ensure a simple way to connect software components dynamically. This style has as a principle the use of RESTful Web Services in order to achieve a uniform interface simple and functional. This paper presents a collaborative environment to support the development of RESTful Web Services using the Model Driven Development paradigm. It is intended to show the benefits of MDD applied to Web Engineering and also the advantages presented by collaboration in this scenario. It was also performed a experiment to prove the efficiency of the collaborative environment and benefits achieved by the same

Tempo e aspecto gramatical no Déficit Específico de Linguagem / Tense and grammatical aspect in Specific Language Impairment

Arvigo, Maria Cláudia, 1980- 18 August 2018 (has links)
Orientador: Ruth Elisabeth Vasconcellos Lopes / Dissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Estudos da Linguagem / Made available in DSpace on 2018-08-18T05:22:59Z (GMT). No. of bitstreams: 1 Arvigo_MariaClaudia_M.pdf: 2310306 bytes, checksum: bb233c9ad0e9205ce7d4d95f43360732 (MD5) Previous issue date: 2011 / Resumo: Crianças acometidas pelo Déficit Específico de Linguagem (DEL) apresentam dificuldades na composição da estrutura gramatical de sua língua. Uma das dificuldades mais documentadas refere-se à morfologia de tempo, sendo que esta categoria funcional pode ser omitida assistematicamente ou substituída de forma irregular. Tempo e Aspecto encontram-se relacionados intrinsecamente, impossibilitando o estudo do primeiro sem a observação do segundo. Estudos anteriores referem que crianças com DEL apresentam bom reconhecimento de temporalidade (passado, presente e futuro), mas encontram relativa dificuldade em compreender a relação entre eventos completos/ incompletos e o passado progressivo (aspecto gramatical imperfectivo). Este comportamento seria resultado de uma baixa sensibilidade às propriedades aspectuais, evidenciada pela pouca ou nenhuma variação do desempenho com relação ao aspecto lexical. Tais resultados referem-se a pesquisas com crianças anglófonas, já o presente estudo buscou verificar se o mesmo ocorre em crianças com DEL adquirindo o português brasileiro. Resultados encontrados demonstram que os indivíduos participantes apresentam variações em seu comportamento que podem ser atribuídas à presença do aspecto lexical, enfraquecendo a hipótese da insensibilidade aspectual, ao menos no que se refere ao português brasileiro. Outra questão abordada foi a distinção entre evento e não-evento por meio de pares de figuras representando um evento e um objeto tanto com verbos e nomes existentes na língua como com palavras novas ou pseudopalavras. O que se viu foi o melhor desempenho com verbos, demonstrando sensibilidade às pistas morfológicas ao menos com palavras pertencentes ao léxico / Abstract: Children affected by the Specific Language Impairment (SLI) have difficulties with the composition of the grammatical structure of their language. One of the most documented difficulties concerns the tense morphology, a functional category that can be unsystematically omitted or irregularly replaced. Tense and Aspect are intrinsically linked, making it impossible to study the first without observing the latter. According to previous researches, children with SLI show good recognition of temporality (past, present and future), but find relative difficulty in understanding the relationship between complete/ incomplete events and past progressive (imperfective grammatical aspect). This behavior would be the result of a low sensitivity to the aspectual proprieties, evidenced by little or no change in performance with regards to lexical aspect. These results have been seen in other researches with English-speaking children, and this study sought to verify whether the same occurs in children with SLI acquiring Brazilian Portuguese. Results have shown that individuals vary in their behavior, which can be attributed to the presence of lexical aspect, weakening the hypothesis of aspectual insensitivity, at least in relation to Brazilian Portuguese. Another issue discussed was the distinction between event and nonevent by means of pairs of figures representing an event and an object with both real verbs and real nouns as with new verbs and nouns or pseudo-words. What we saw was that the best performance happened with verbs, demonstrating sensitivity to morphological clues at least with words belonging to the lexicon / Mestrado / Linguistica / Mestre em Linguística

雲端多租戶互動展演平台的設計與實作 / Design and Implementation of a Multi-tenant Cloud Platform for Cyber-Physical Interactive Performance Art

王佑霖, Wang, You Lin Unknown Date (has links)
傳統展演中,觀眾和表演者被視為是兩個獨立的個體,表演者與表演者間及表演者與觀眾間互動不多,若使用穿戴式裝置結合科技與藝術的「虛實互動數位展演」,能協助營造現場的互動氣氛,是既新穎又富有創意的表演模式,還能結合故事劇情與觀眾互動,此種互動的情境氛圍,會比一般的資訊傳遞更容易讓觀眾有所感受。 而目前許多表演活動的展演特效系統,都是由特效控制技術人員根據展演人員的動作與節目進程來呈現。如果由展演人員自行操作、建置與管理的話,便需要瞭解特效控制的相關技術,此外也需要和技術人員互相溝通與合作。而彼此觀念、資訊與背景的不同,難免容易造成控制上的失誤、延遲或是溝通不良導致表演效果不佳以致於觀眾不好的視聽感受。基於上述問題,本研究將設計一個基於多租戶概念的雲端互動展演系統整合平台,展演人員只需透過網路連結至展演系統網站,配合連網感應器的穿戴式裝置,不需自行建置、管理系統平台,登入後可依個人需求使用直覺圖形化邏輯編輯器,使用滑鼠拖拉,控制需求,不需繁複的技術教學訓練,便根據穿戴式裝置回傳的感測訊號做出響應式的展演效果變化,達到展演人員可簡單好上手地自行操作展演特效系統,減少與特效控制技術人員合作上的失誤。 / In traditional performance art, viewers and performers are regarded as two independent individuals. There is less interaction between performers and performers, performers and audiences. If wearable devices are used in the "cyber-physical interactive digital performance art", it can help create an interactive atmosphere in the scene. It is a creative, innovative mode of performance, and it also creates a combination between scenario and the interaction of the audiences. The interactive atmosphere is easier for the audience to be affected than ordinary information transmission. Currently, many special effects are presented by the technical staff. They are based on the performers and progression of show. If the special effects are managed by the performer-selves, they need to understand the relative technologies. In addition, they have to cooperate and communicate with technical staff. However, the difference of concept and background between each other, it's hard to avoid the mistake, delay, or misunderstanding of control. It may cause that the poor performance bring audience about the bad auditory and visual feeling. According to above issues, this study will design and implement a multi-tenant cloud platform for cyber-physical interactive performance art. The performers just connect to the performance art system website via the Internet, with the wearable device, and they do not need to set up and manage system platform by themselves. They log in the website, with the GUI editor, and use mouse to control demand. Without complex technical training, the variety of special effects are presented which based on the wearable device’s signal. We suppose that the platform makes the performers operate special effects system by themselves simply and easily. It also reduces the misunderstanding with the technical staff.

An In Depth Analyses of Specific Language Impairment as Compared to Other Developmental Disorders

Stein, Adam W, Mr. 01 January 2013 (has links)
Specific language impairment (SLI), defined as a disproportionate difficulty in learning language despite having normal hearing, intelligence, and no known neurological or emotional impairment, has been shown to share similar cognitive characteristics with individuals with attention deficit hyperactive disorder (ADHD). However, little research has investigated the dissimilarities in these two different developmental disorders. Children with SLI also show many similar symptoms with individuals diagnosed with dyslexia. The aim of these studies is to get a better understanding of cognitive differences between SLI and ADHD, and the cognitive similarities between SLI and dyslexia. Tests of both verbal and non-verbal measures of working memory, IQ, and academic performance were administered to all groups. It was hypothesized that children with SLI would perform worse on verbal measures due to their language deficits but perform better on non-verbal measures than children with ADHD. It was also predicted that children with SLI will perform similarly, but worse than children with dyslexia. Results from the SLI/ADHD experiment confirm this pattern: children with SLI performed poorer than children with ADHD on all verbal cognitive measures. When looking at the non-verbal measures of abilities, the SLI group outperformed the ADHD group on working memory and IQ scores but not academic performance scores. Results from the SLI/Dyslexia experiment also confirmed what was predicted. Children with dyslexia outperformed their SLI counterparts on all cognitive measures. A possible explanation for these finding is that there are fewer classroom-based programs designed specifically to support children with SLI.

Système de Mesure Mobile Adaptif Qualifié / Mobile System for Adaptive Qualified Measurement

Bourgeois, Florent 21 March 2018 (has links)
Les dispositifs matériels mobiles proposent des capacités de mesure à l'aide de capteurs soit embarqués, soit connectés. Ils ont vocation à être de plus en plus utilisés dans des processus de prises de mesures. Ils présentent un caractère critique dans le sens où ces informations doivent être fiables, car potentiellement utilisées dans un contexte exigeant. Malgré une grande demande, peu d'applications proposent d'assister les utilisateurs lors de relevés exploitant ces capacités. Idéalement, ces applications devraient proposer des méthodes de visualisation, de calcul, des procédures de mesure et des fonctions de communications permettant la prise en charge de capteurs connectés ou encore la génération de rapports. La rareté de ces applications se justifie par les connaissances nécessaires pour permettre la définition de procédures de mesure correctes. Ces éléments sont apportés par la métrologie et la théorie de la mesure et sont rarement présents dans les équipes de développement logiciel. De plus, chaque utilisateur effectue des activités de mesure spécifiques au domaine de son champ d'activités, ce qui implique le développement d'applications spécifiques de qualité pouvant être certifiées par des experts. Ce postulat apporte la question de recherche à laquelle les travaux présentés répondent: Comment proposer une approche pour la conception d’applications adaptées à des procédures de mesures spécifiques. Les procédures de mesure pouvant être configurées par un utilisateur final La réponse développée est une "plateforme" de conception d'applications d'assistance à la mesure. Elle permet d'assurer la conformité des procédures de mesures sans l'intervention d'expert de la métrologie. Pour cela elle est construite en utilisant des concepts issus de la métrologie, de l'Ingénierie Dirigée par les Modèles et de la logique du premier ordre. Une étude du domaine de la métrologie permet de mettre en évidence la nécessité d'une expertise des procédures de mesure impliquées dans les applications. Cette expertise comprend des termes et des règles assurant l'intégrité et la cohérence d'une procédure de mesure. Un modèle conceptuel du domaine de la métrologie est proposé. Ce modèle conceptuel est ensuite intégré au processus de développement d'une application. Cette intégration se fait par un encodage de ce modèle conceptuel sous la forme d'un schéma des connaissances de la métrologie en logique du premier ordre. Il permet, la vérification du respect des contraintes inhérentes à la métrologie dans une procédure de mesure. Cette vérification est réalisée en confrontant les procédures de mesures au schéma sous forme de requêtes. Ces requêtes sont décrites à l'aide d'un langage proposé par le schéma. Les applications d'assistance à la mesure nécessitent d'exposer à l'utilisateur un processus de mesure impliquant relevés et affichages de mesures étape par étape. Cela implique de pouvoir décrire un processus de mesure et d'en définir les interfaces et le schéma d'évolution. Pour cela, un éditeur d'application est proposé. Cet éditeur propose un langage spécifique dédié à la description d'applications d'assistance à la mesure. Ce langage est construit à partir des concepts, formalismes et outils proposés par l'environnement de métamodélisation Diagrammatic Predicate Framework (DPF). Le langage comporte des contraintes syntaxiques prévenant les erreurs de construction au niveau logiciel tout en réduisant l'écart sémantique entre l'architecte logiciel l'utilisant et un potentiel expert de la métrologie. [...] / Mobile devices offer measuring capabilities using embedded or connected sensors. They are more and more used in measuring processes. They are critical because the performed measurements must be reliable because possibly used in rigorous context. Despite a real demand, there are relatively few applications assisting users with their measuring processes that use those sensors. Such assistant should propose methods to visualise and to compute measuring procedures while using communication functions to handle connected sensors or to generate reports. Such rarity of applications arises because of the knowledges required to define correct measuring procedures. Those knowledges are brought by metrology and measurement theory and are rarely found in software development teams. Moreover, every user has specific measuring activities depending on his field of work. That implies many quality applications developments which could request expert certification. These premises bring the research question the presented works answer : What approach enables the conception of applications suitable to specific measurement procedures considering that the measurement procedures could be configured by the final user. The presented works propose a platform for the development of measuring assistant applications. The platform ensure the conformity of measuring processes without involving metrology experts. It is built upon metrology, model driven engineering and first order logic concepts. A study of metrology enables to show the need of applications measuring process expert evaluation. This evaluation encompasses terms and rules that ensure the process integrity and coherence. A conceptual model of the metrology domain is proposed. That model is then employed in the development process of applications. It is encoded into a first order logic knowledge scheme of the metrology concepts. That scheme enables to verify that metrology constraints holds in a given measuring process. The verification is performed by confronting measuring processes to the knowledge scheme in the form of requests. Those requests are described with a request language proposed by the scheme. Measuring assistant applications require to propose to the user a measuring process that sequences measuring activities. This implies to describe a measuring process, and also to define interactive interfaces and sequencing mechanism. An application editor is proposed. That editor uses a domain specific language dedicated to the description of measuring assistant applications. The language is built upon concepts, formalisms and tools proposed by the metamodeling environment : Diagrammatic Predicat Framework (DPF). The language encompasses syntactical constraints that prevent construction errors on the software level while reducing the semantical gap between the software architect using it and a potential metrology expert. Then, mobile platforms need to execute a behaviour conforming to the editor described one. An implementation modelling language is proposed. This language enables to describe measuring procedures as sequences of activities. Activities imply to measure, compute and present values. Quantities are all abstracted by numerical values. This eases their computation and the use of sensors. The implementation model is made up of software agents. A mobile application is also proposed. The application is built upon a framework of agents, an agent network composer and a runtime system. The application is able to consider an implementation model and to build the corresponding agent network in order to propose a behaviour matching the end users needs. This enables to answer to any user needs, considering he can access to the implementation model, without requiring to download several applications.

Evolution of domain-specific languages depending on external libraries

Fall, Khady 11 1900 (has links)
L'ingénierie dirigée par les modèles est une approche qui s'appuie sur l'abstraction pour exprimer davantage les concepts du domaine. Ainsi, les ingénieurs logiciels développent des langages dédiés (LD) qui encapsulent la structure, les contraintes et le comportement du domaine. Comme tout logiciel, les LDs évoluent régulièrement. Cette évolution peut se produire lorsque l'un de ses composants ou le domaine évolue. L'évolution du domaine ainsi que l'évolution des composants du LD et l'impact de cette évolution sur ceux-ci ont été largement étudiés. Cependant, un LD peut également dépendre sur d'éléments externes qui ne sont pas modélisées. Par conséquent, l'évolution de ces dépendances externes affecte le LD et ses composants. Actuellement, les ingénieurs logiciels doivent évoluer le LD manuellement lorsque les dépendances externes évoluent. Dans ce mémoire, nous nous concentrons sur l'évolution des librairies externes. Plus spécifiquement, le but de cette thèse est d'aider les ingénieurs logiciels dans la tâche d'évolution. À cette fin, nous proposons une approche qui intègre automatiquement les changements des librairies externes dans le LD. De plus, nous offrons un LD qui supporte l'évolution des librairies Arduino. Nous évaluons également notre approche en faisant évoluer un éditeur de modélisation interactif qui dépend d'un LD. Cette étude nous permet de montrer la faisabilité et l'utilité de notre approche. / Model-driven engineering (MDE) is an approach that relies on abstraction to further express domain concepts. Hence, language engineers develop domain-specific languages (DSLs) that encapsulates the domain structure, constraints, and behavior. Like any software, DSLs evolve regularly. This evolution can occur when one of its components or the domain evolves. The domain evolution as well as the evolution of DSL components and the impact of such evolution on them has been widely investigated. However, a DSL may also rely on external dependencies that are not modeled. As a result, the evolution of these external dependencies affects the DSL and its components. This evolution problem has yet to be addressed. Currently, language engineers must manually evolve the DSL when the external dependencies evolve. In this thesis, we focus on the evolution of external libraries. More specifically, our goal is to assist language engineers in the task of evolution. To this end, we propose an approach that automatically integrates the changes of the external libraries into the DSL. In addition, we offer a DSL that supports the evolution of the Arduino libraries. We also evaluate our approach by evolving an interactive modeling editor that depends on a DSL. This study allows us to demonstrate the feasibility and usefulness of our approach.

Profiling language in young urban English additional language learners

Naude, Elsie 03 November 2006 (has links)
The development of language and communication skills in young children is directly related to future academic success. Young children who are at risk for language impairment should, therefore, be identified as early as possible so that their language development may be optimised. Multilingualism, which has become a universal phenomenon, may mask the presence of language impairment if the pre-school teacher or speech-language therapist is not proficient in the young multilingual learner’s primary language. In some urban areas of South Africa, where many languages are represented in each pre-school classroom, it is likely that the teacher or therapist will lack proficiency in the primary language of quite a number of the pre-school learners. In these contexts, the language of mutual understanding is English and assessment of learners’ language behaviour will also be conducted in English. Against this background the aim of this study was to determine the feasibility of constructing a profile of typical English language behaviours for pre-school EAL learners in a circumscribed urban area. The profile is intended to provide speech-language therapists and pre-school teachers in collaborative practice with a dual-purpose tool: an instrument for identifying those learners who are at risk for language impairment/language learning disabilities, and a means of obtaining guidelines for the development of an appropriate programme for facilitating language development. The literature study reviewed the language diversity in South African pre-schools, and the role of speech-language therapists in these multilingual pre-schools. The aspects of language to be included in a profile of typical English language behaviours for young EAL learners were discussed. A quantitative descriptive research design was selected. The language database for 30 EAL pre-schoolers from a circumscribed geographical area was collected during 20 minutes of conversation between each pre-school participant and a trained speech-language therapist who acted as research fieldworker. The language data was analysed to identify typical language behaviours relating to language form, language content and language use. The results show that it was possible to construct a profile of typical English language behaviours for nine aspects of language form, one aspect of language content, and six aspects of language use. The information was used to construct two versions of a profile of typical English language behaviours, as well as a profile of risk indicators for language impairment in the specified group of EAL pre-schoolers. An action plan was designed to indicate the way in which these three profiles – the comprehensive profile, the essential classroom profile, and the profile of risk indicators – may be used by the collaborative team of speech-language therapist and pre-school teacher for language assessment, the identification of learners with language impairment, and the facilitation of language development for all EAL learners. / Thesis (DPhil (Communication Pathology))--University of Pretoria, 2007. / Speech-Language Pathology and Audiology / Unrestricted

Modelom upravljani razvoj arhitekture Senzor Veb mreža / Model Driven Development of Sensor Web Networks Architecture

Vujović Vladimir 28 April 2016 (has links)
<p>Primjena Internet protokola u uređajima sa ograničenim resursima, dovodi do radikalne promjene Interneta i pojave potpuno novog koncepta pod nazivom Internet stv&acirc;ri &ndash; Internet of Things (IoT), čiji je jedan od osnovnih gradivnih elemenata Senzor Web (SW) čvor. SW čvor predstavlja elementarni &ldquo;resurs&rdquo; u SW mreži koja se po svojoj prirodi može posmatrati kao nestrukturirana kolekcija gradivnih elemenata koji se mogu dinamički orkestrirati u virtuelne klastere, odnosno u arhi-tekturu. Cilj disertacije predstavlja unapređenje procesa razvoja arhitekture sistema baziranih na SW mrežama uz oslonac na dinamičko generisanje servisnog sloja u svrhu povećanja produktivnosti, održivosti i smanjenja troškova razvoja. Pod unapređenjem procesa razvoja arhitekture smatra se analiza, integracija i prilagođavanje postojećih sistema i pristupa projektovanja arhitekture senzorskih mreža, kao i sistema baziranih na IoT konceptima. U tu svrhu definisana je arhitektura SW mreža, kreiran domenski specifičan jezik, interaktivni grafički editor i alat za automatsku transforma-ciju modela u implementacione klase. U sklopu teze izvršena je i eksperimentalna verifikacija predloženog modela i razvojnog okruženja, čime je dokazana njhova praktična primjena.</p> / <p>The use of Internet protocols in limited resources devices contributes to radical changes in the Internet and the emergence of an entirely new concept called the Internet of Things (IoT), consisted of the Sensor Web (SW) nodes as one of the basic building blocks. SW node is the elementary &quot;resource&quot; in the SW Network, which by their nature can be seen as an unstructured collection of blocks that can be dynamically orchestrated into the virtual cluster, or in the architecture. The aim of this thesis is to improve the process of developing a system archite-cture based on SW networks, relying on the dynamic generation of the service layer in order to increase productivity, sustainability and cost of development. The improvement of the architecture development process includes analysis, integration and adaptation of existing systems and sensor network architecture design approaches, as well as systems based on the IoT concepts. For this purpose, the archite-cture of the SW Network is defined, a domain-specific language has been created as well as interactive graphics editor and a tool for automatic transformation of models into the implementation class. As part of the dissertation, the experimental verification of the proposed model and the development environment were carried out demonstra-ting their practical application.</p>
