This study explores complexity metrics for business artifact process models described by Case Management Model and Notation (CMMN). Process models are usually described using Business Process Management (BPM), which is a relatively mature discipline with a large number of practitioners. Over the last few decades a new way of describing data intensive business processes has emerged in BPM literature, for which traditional BPM is no longer adequate. This emerging method, used to describe more flexible processes, is called business artifacts with Guard-Stage-Milestone (GSM). The work on GSM influenced CMMN, which was created to fill a market need for more flexible case management processes for knowledge workers. Complexity metrics have been developed for traditional BPM models, such as the Business Process Model and Notation (BPMN). However, traditional BPM is not suitable for describing GSM or CMMN process models. Therefore, complexity metrics developed for traditional process models may not be applicable to business artifact process models such as CMMN. This study addresses this gap by exploring complexity metrics for business artifact process models using CMMN. The findings of this study have practical implications for the CMMN standard and for the commercial products implementing CMMN. This research makes the following contributions: • The development of a formal description of CMMN using first-order logic. • An exploration of the relationship between CMMN and GSM and the development of transformation procedures between them. • A comparison between the method complexity of CMMN and other popular process methods, including BPMN, Unified Modeling Language (UML) Activity diagrams, and Event-driven Process Charts (EPC). • The creation of a systematic literature review of complexity metrics for process models, which was conducted in order to inform the creation of CMMN metrics. • The identification of a set of complexity metrics for the CMMN standard, which underwent theoretical and empirical validation. This research advances literature in the areas of method complexity, complexity metrics for process models, declarative processes, and research on CMMN by characterizing CMMN method complexity, identifying complexity metrics for CMMN, and exploring the relationship between CMMN and GSM. / School of Computing / Ph.

The present study was conducted to identify Caracu, Curraleiro Pé-Duro, Pantaneiro and Nellore bovine breeds by trichological morphology and morphometry, as well as validate the technique compared with genetic characterization. This study was presented in chapters. First, a review on trichology application on mammal species and breeds identification with basic concepts necessary for understanding trichology analysis and its applications. The second chapter was composed by characterization of guard hair of Caracu, Curraleiro Pé-Duro and Pantaneiro (Bos taurus taurus) and of Nellore (Bos taurus indicus), Brazilian bovine breeds, through trichology analysis, to assess the possibility of using this technique as a racial marker. Morphological and morphometric descriptions were held by 160 cattle (40 animals/breeds). Sub-samples of each bovine were made until quality slides were obtained. Morphology was determined through dichotomous keys and measures were carried out in the cuticle scale and in the hair shield matrix. Results indicated that trichology and genetic evaluation were similar in the point of view of classification of individuals within racial groups. Therefore, the technique can be considered useful as a marker for bovine breeds. / A tricologia é um método que permite analisar os padrões microestruturais de arranjos de escamas cuticulares e células medulares encontradas em pelos guarda de mamíferos. O presente estudo foi conduzido com o objetivo de identificar as raças bovinas Caracu, Curraleiro Pé-Duro, Pantaneiro e Nelore por meio da morfologia e morfometria tricológica, bem como validar a técnica comparando com resultados da caracterização genética. Esse estudo foi apresentado em forma de capítulos, com uma revisão de literatura sobre a aplicação da tricologia na identificação de espécies de mamíferos e de raças de interesse zootécnico, onde foram disponibilizadas informações sobre os conceitos básicos necessários ao entendimento da análise tricológica e suas aplicações. O capítulo seguinte foi composto pela caracterização de pelos guarda das raças bovinas Caracu, Curraleiro Pé-Duro e Pantaneiro (Bos taurus taurus) e da raça Nelore (Bos taurus indicus), por meio de análise tricológica, a fim de avaliar a possibilidade de uso desta técnica como marcador racial. Realizaram-se descrições morfológicas e morfométricas dos pelos de 160 bovinos (40 animais/raça). De cada bovino foram feitas subamostras de pelos até serem obtidas lâminas de qualidade. A morfologia foi determinada por meio de chave dicotômica e as medidas foram realizadas na escama cuticular e na medula e os resultados dessa metodologia foram comparados à caracterização genética dos animais amostrados. Os resultados indicaram que a tricologia e a avaliação genética foram similares no ponto de vista de classificação dos indivíduos dentro dos grupos raciais. Portanto, a técnica pode ser considerada útil como marcador racial para raças bovinas.

[pt] Os esquemas de alocação fixa de canais - FCA - conferem aos Sistemas de Comunicação Móveis Celulares estabilidade com o custo da necessidade de um pré-planejamento de freqüências, trazendo como conseqüência a baixa tolerância à variabilidade de tráfego. Algoritmos de alocação dinâmica de canais - DCA - tem sido propostos por diversos autores com o intuito de minimizar estes problemas, permitindo ao sistema flexibilidade no momento da escolha do canal candidato para servir a uma ligação. Esquemas de alocação híbrida de canais - HCA, combinam as técnicas de alocação fixa com alocação dinâmica de canais, conferindo ao mesmo tempo estabilidade e flexibilidade ao sistema.Este trabalho compara os algoritmos FCA, DCA e HCA sobre um mesmo cenário de simulação, permitindo analisar o desempenho dos mesmos. O esquema FCA utilizado é o mais simples, onde o primeiro canal com o nível aceitável de relação sinal interferência é escolhido para ser alocado. O esquema DCA utiliza a técnica de Segregação de Canais - CS, permitindo ao sistema maior flexibilidade no momento da escolha do canal candidato, devido a não existência do pré-planejamento de freqüências. O terceiro algoritmo, HCA, combina os dois esquemas anteriores. Ao final, será analisado o impacto de se priorizar o procedimento de handoff utilizando-se a técnica conhecida como Canais de Guarda. / [en] Fixed channel assignment -FCA- brings to the Cellular Communication Systems stability at the cost of the use of frequency planning, leading to low tolerance to traffic variability. Dynamic channel assignment -DCA- algorithms have been proposed by several authors in order to minimize these problems,incorporating flexibility to the system with respect to channel selection. Hybrid channel assignment - HCA- combines the techniques of fixed and dynamic channel assignment, giving to the system stability and flexibility at the same time. This work compares the FCA, DCA and HCA algorithms on the same simulation scenario, allowing a complete analysis of these approaches. The FCA used is the simplest. In this algorithm, the first channel with an acceptable level of signal to interference ratio is chosen to be allocated. The DCA uses the technique of Channel Segregation -CS-, a distributed self-learning algorithm that is shown to yield very good performance. The third algorithm,HCA, combine the two previous techniques. At the end, the impact of prioritizing the procedure of handoff will be analyzed, using the technique known as Guard Channel.

This dissertation explores the growing field of study around Maritime Security. While an increasingly common sub-heading in American naval strategy documents, maritime security operations are largely framed around individual threats (i.e. counter-piracy, counter-terrorism, counter-narcotics). Here, we endeavor to explore how a seemingly disparate set of transnational issues fit into a more coherent framework to give greater theoretical substance to the notion of Maritime Security as a distinct concept. In particular, we examine, as our research question, whether the Broken Windows theory, a criminological construct of social disorganization, provides the lens through which to theorize maritime security in the littorals. By extrapolating from criminology, this dissertation engages with a small but growing impulse in studies on insurgencies, terrorism, and piracy to look beyond classic theories of security to better understand phenomena of political violence. To evaluate our research question, we begin by identifying two critical components of the Broken Windows theory, multidimensionality and context specificity. Multidimensionality refers to the web of interrelated individuals, organizations, and infrastructure upon which crime operates. Context specificity refers to the powerful influence of an individual or community's environment on behavior. These two themes, as explored in this dissertation, are brought into stark relief through an application of the Broken Windows theory. Leveraging this understanding of the theory, we explore our research question by employing process-tracing and detailed descriptions across three case studies (one primary and two illustrative)—the Caribbean Basin, the Gulf of Guinea, and the Straits of Malacca and Singapore. In so doing, we demonstrate how applying the lens that Broken Windows provides yields new and interesting perspectives on maritime security. As a consequence, this dissertation offers an example of a theoretical framework that provides greater continuity to the missions or threats frequently binned under the heading of maritime security, but infrequently associated with one another in the literature.

Among the four valves of the heart, the aortic valve (AV) is frequently affected by disease. When progressive dilatation of the valve produces a leak when the valve should close (regurgitation), repair may be possible. AV repair is a desirable option because, contrary to AV replace-ment using a prosthesis, it does not require life-long anticoagulation treatment, and retains the original tissues that naturally combat structural degradation. All the AV repair procedures developed by cardiac surgeons require a good stabilization of the ventriculo-aortic junction (VAJ) diameter, through annuloplasty or reimplantation, for long-term success. In the present work, a preliminary design for a new type of annuloplasty ring is proposed that surgeons could tailor to the each valve’s shape and suture inside the VAJ. The design consists in wrapping a commonly available surgical biomaterial into a ring of controlled radial flexibility. For sizing and material selection, several models of increasing complexity were created to account for the anisotropic, hyperelastic nature of all the materials involved. First, an analytical model was programmed in MATLAB to assess the radial flexibility of annuloplasty rings formed with different biomaterials and select those that could match the physiological VAJ radial flexibility between systolic and diastolic pressures. The same program was also used to reproduce the experimental radial and longitudinal stretches of the human VAJ from 0 to 140 mmHg pressures. The analytical models were used to calibrate the parameters of independent finite element (FE) models of the VAJ and ring. Finally, the FE approach was extended to simulate the ring after suturing inside the VAJ, to determine the radial flexibility of the assembly under pulsatile pressure. Supple Peri-Guard® bo-vine pericardium patches used in transverse orientation emerged as the best currently available material option for the proposed ring, although a material providing more physiological radial flexibility would be desirable.
