Karlsson, Magnus. "XML to RDBMS." Thesis, KTH, Teleinformatik, 2000. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-93542.
Full textAbstract:
The Extensible Markup Language (XML) becomes more and more widespread as nearly all major players on the market today have accepted XML as an industry standard for exchanging information between server based products. Thus thousands of XML dialects have emerged since XML 1.0 became a W3C recommendation in February 1998. Corus Technologies AB has developed a server-based product called Corus/ALS© (Application Linking System) that makes it possible to connect client systems with different data representations to each other. A relational database model for each of the client systems is created and the translation from one data representation to another is done with stored procedures in the database. This thesis introduces a solution for how to store and retrieve XML documents in a Relational Database Management System (RDBMS) from any of the XML dialects that has emerged since XML 1.0 became a W3C recommendation. After a XML document has been stored in the database in a normalized way, the stored procedures in the Corus/ALS© database can be used to transform it to another XML dialect (or another format supported by the Corus/ALS© system). This will make it possible to translate any XML document to any other XML format. An XML interpreter was implemented and this implementation verified the theories in this thesis.

Full textAbstract:
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, NevadaOne problem facing telemetry engineers is the ability to easily translate telemetry attributes from one system to another. Engineers must develop a written set of attributes that define a given telemetry stream and specify how the telemetry stream is to be transmitted, received, and processed. Telemetry engineers take this document and create the configuration for each product that will be exposed to the telemetry stream (airborne, ground, flight line). This process is time-consuming and prone to error. L-3 Telemetry-West chose to implement a solution using relational databases and eXtensible Markup Language (XML) to solve this and other issues.

Full textAbstract:
Manually writing SQL queries for Relational Database Management Systems (RDBMS) testing can be very tedious depending on the database complexity. The focus of this thesis is to develop three approaches to automatically generate SQL queries based on a given database instance. These queries can then be used to evaluate the configuration of a RDBMS. The generated queries are only partial components in RDBMS testing. However, they do reduce the amount of work required to perform such configuration assessment. The three presented approaches generate well-formed and semantically meaningful queries (i.e. queries with no logical contradictions). The first approach only consists of a context-free grammar (CFG). The second uses a CFG with an exclusion list. The third uses a CFG with a binary classification machine learning model. The results show that the binary classification algorithm approach outperforms the other two in terms of generating a higher proportion of semantically meaningful queries.

Full textAbstract:
Corporate data plays a very important role in the business processing nowadays. It is not only used as the mediate that records the personal information for the business organization, but also keeps tracks of the valuable data about its customers and transaction history. Any wise company has to make sure that its business data is safely and correctly stored. There are many strategies used to guarantee the data security and correctness. Referential integrity (RI) verifications as a one way is widely adopted in the database system to make sure the data is correct and consistent. RI is a property of data, which is usually implemented as constraint within a relational database management system (RDBMS). It is used to establish relationships for two referenced tables in RDBMS, such that a column of a table in a declared relationship could only contain the values from the relative column of another table. The goal of RI constraint is to enable RDBMS to have a reliable mechanism which can ensure the database integrity and data consistency when doing a insert, update or delete into a database and none of incorrect manipulation is accepted. Most mature and successful commercial database products such as Oracle and Microsoft SQL Server support the definition of RI constraints internally; On the other hand, the one which does not support to enforce RI rules can be only called a database management system (DBMS) such as Mnesia. Mnesia is an Erlang implemented distributed DBMS and especially designed for telecommunication applications which require fast real-time and non-stop services. However in the domain of telecommunication applications, RI constraints were not critical features for the database system so Mnesia left them to the programmers. In this case, RI constraints have to be implemented outside Mnesia. Klarna AB is a financial company who supplies easy payment solution for online customers. Kred system is an Erlang implemented product which is running by Klarna AB for dealing with their daily business transactions. In this Kred system, Mnesia is used as the DBMS and the RI constraints are implemented into the application layer of the system. It is a stable system however the RI constraints implementation strategy is not efficient. Hence in the following thesis, a research is investigated to find out a new solution for this problem. In this new solution, the RI constraints implementation will be separated from the database layer. A new layer rdbms with RI enforcement will be established and inserted into the middle of the application layer and the DBMS layer. The reason for calling the new layer rdbms is that a new software called rdbms will be used to implement this new layer. Software rdbms is an Erlang implemented module which could assist Mnesia to do data type and RI constraints verifications. Hence the thesis will introduce the procedure of integrating rdbms into Kred system, programming on rdbms in order to implement RI constraints for Kred system. Later, an evaluation will be carried out to see if software rdbms is mature and efficient enough to be integrated into the live system.

Full textAbstract:
Updates in RDF stores have recently been standardised in the
SPARQL 1.1 Update specification. However, computing answers entailed by
ontologies in triple stores is usually treated orthogonal to updates. Even the W3C's
recent SPARQL 1.1 Update language and SPARQL 1.1 Entailment Regimes specifications
explicitly exclude a standard behaviour how SPARQL endpoints should
treat entailment regimes other than simple entailment in the context of updates. In
this paper, we take a first step to close this gap. We define a fragment of SPARQL
basic graph patterns corresponding to (the RDFS fragment of) DL-Lite and the
corresponding SPARQL update language, dealing with updates both of ABox and
of TBox statements. We discuss possible semantics along with potential strategies
for implementing them. We treat both, (i) materialised RDF stores, which store all
entailed triples explicitly, and (ii) reduced RDF Stores, that is, redundancy-free
RDF stores that do not store any RDF triples (corresponding to DL-Lite ABox
statements) entailed by others already.Series: Working Papers on Information Systems, Information Business and Operations

Full textAbstract:
The current global and data intensive outlook of research provides new opportunities and challenges for HEIs including effective and sustainable RDM. As a growing area of interest in the global research arena, experiences from developed countries have dominated the body of literature on RDM. This study is in part, to fill this gap by assessing the state of the art of RDM and institutional preparedness at the University of Ghana (through existing data management activities and capabilities) in order to develop a plan for implementation.
The study used a qualitative case study method and gathered data using semi-structured interviews and document analysis. Thematic analysis method was used to analyse the data collected. A total of seven respondents (five service providers and two senior researchers) were selected purposively using two sampling techniques ("priori criteria sampling" and snowball sampling). Criteria were set for their inclusion and each respondent provided information about institutional support, capabilities, policies and expectations on RDM.
The findings of the study revealed a number of RDM related activities, these include support for collaborative research, support for data analysis and computational science, guidance on RDM and grant applications as well as support for storage and high-speed connectivity to facility the research enterprise at UG. In terms of capabilities, no specific RDM policy was identified, existing infrastructure identified include an HPC cluster, a private cloud facility (HP Cloud Matrix), an Institutional repository (UGSpace), an institutional Google Drive platform, data analysis packages (NVivo and SPSS) and a robust network and security infrastructure. These were not necessarily provisioned for RDM purposes. Also, the findings show that staff do not possess the necessary skills or adequate knowledge to fully support RDM at UG.
In terms of the specific objectives of the study, the results of the semi-structured interviews and document analysis provided an understanding of the current situation (i.e. requirements, current activities and capabilities at the UG) which is the first objective of the study. These findings were then benchmarked against the EPSRC policy framework following the outline of the DCC CARDIO Matrix and using the optimal desirable expectation or level of development as the standard for comparison. This was useful in identifying gaps in RDM awareness, support and capabilities at UG which is the second objective of the study. To achieve the third objective, which was identifying priority areas for RDM development, the researcher examined both initial findings (i.e. findings on requirements, current activities and capabilities identified under the first objective as well as the gaps identified in the second objective) and proposed six broad areas where UG must focus its RDM development agenda. Finally, the six broad areas proposed in objective three were further cascaded into a number of specific initiatives and tasks to be implemented. This was done taking cognisance of the potential of current infrastructure, gaps identified in institutional awareness and capabilities as well as essentials for a cultural changed. The study concluded that RDM at the University of Ghana is currently underdeveloped but with immense potential for growth. While a few RDM related activities were identified, existing capabilities were generally found to be inchoate, uncoordinated and not formally instituted.
The study recommended six main areas where the UG should focus RDM development, these include: constituting a steering group to spearhead and coordinate RDM development at the UG, developing a coordinated policy framework for RDM at UG, streamlining existing technical infrastructure to support data management requirements, creating opportunities for RDM training and capacity development for professional staff, researchers and students, developing services to support requirements, and exploring internal funding strategies to facilitate RDM development and support at the UG. The study also recommends that the academic community at the UG should be actively engaged throughout the RDM development process as this is critical to ensure that the eventual solutions are fit for purpose and acceptable.Mini Dissertation (MIT)--University of Pretoria, 2016.

Full textAbstract:
The Ethernet technology has advanced from the era of fast Ethernet to the era of gigabit ethernet. The gigabit routers currently available in the market are employing expensive hardware based implementations for improving the throughput [6], which makes the overall cost of the device prohibitively high. In this thesis the author reviews the existing router architectures and routing protocols and critiques the shortcomings of the existing implementation. This thesis evaluates the drawbacks in the existing infrastructure and proposes an architecture that provides a solution based on the RDMA protocol. The proposed architecture uses the RDMA protocol for transferring the data payload from the ingress interface to the destination interface. In this research the author also presents an analytical mathematical model that can be used for calculating the delay incurred by a packet, memory utilization and CPU utilization for both architectures. The potential benefits by the use of RDMA protocol are also explained in detail in this thesis. The necessity for modifying the update packet structure in the existing implementation of RIP is discussed in detail. Packet payload handling in both architectures is compared and the advantages in the RDMA protocol based implementation are presented.Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Electrical and COmputer Engineering.

Internet, a connection of networks has unified the world with no boundaries and
limitations. It fulfilled the dream of being virtually present in any part of the world within no time. Over the years internet spanned into every corner of the world and a tremendous growth in the use of internet had been noticed. Internet, with its numerous advantages and support of wide variety of applications has leaded the consumer demand for more bandwidth and high availability to meet his requirements. Addressing these factors great development has taken place in recent years in the field of network technologies. A new era of Gigabit and Terabit Ethernet technologies signify the developments that address the growing demands. With the development in Ethernet technologies the demand for new router architectures that could process the data at gigabit rates also has increased. Many different router architectures have been proposed and implemented to meet these requirements. In this thesis, different router architectures have been studied and explained in detail. Many factors that affect the performance of the router have been reviewed and solutions to overcome the limitations have been addressed in detail. Addressing the solutions for limitations seen in legacy router architectures, the author presents the design, operation of a proposed new routing architecture [16]. The proposed architecture introduces the operation of RDMA into router architecture to minimize the processing and forwarding delay, which improves the performance of routers. The operation of an RDMA enabled router and the operation between two RDMA enabled routers have been clearly explained. The author also presents the mathematical models for evaluating the delay within a router and between two routers, processor utilization and memory utilization for both the legacy and RDMA enabled router architectures. In order to understand the router operation in detail and to enable future researchers to work on router architecture, a simulator with router operation has been built for both the router architectures. The results show that the proposed architectural operation improves the performance of routers even in heavy traffic networks.Wichita State University, College of Engineering, Dept. of Electrical and Computer Science Engineering

CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOCom o crescimento da web semântica, cada vez mais bases de dados em RDF contendo todo tipo de informações, nos mais variados domínios, estão disponíveis para acesso na Internet. Para auxiliar o acesso e a integração dessas informações, esse trabalho apresenta uma ferramenta que permite a geração de aplicações para consultas a bases em RDF e RDFS através da programação por exemplo. Usuários podem criar casos de uso através de operações simples em cima do modelo RFDS da própria base. Esses casos de uso podem ser generalizados e compartilhados com outros usuários, que podem reutilizá-los. Com esse compartilhamento, cria-se a possibilidade desses casos de uso serem customizados e evoluídos colaborativamente no próprio ambiente em que foram desenvolvidos. Novas operações também podem ser criadas e compartilhadas, o que contribui para o aumento gradativo do poder da ferramenta. Finalmente, utilizando um conjunto desses casos de uso, é possível gerar uma aplicação web que abstraia o modelo RDF em que os dados estão representados, tornando possível o acesso a essas informações por usuários que não conheçam o modelo RDF.
Due to increasing popularity of the semantic web, more data sets, containing information about varied domains, have become available for access in the Internet. This thesis proposes a tool to assist accessing and exploring this information. This tool allows the generation of applications for querying databases in RDF and RDFS through programming by example. Users are able to create use cases through simple operations using the RDFS model. These use cases can be generalized and shared with other users, who can reuse them. The shared use cases can be customized and extended collaboratively in the environment which they were developed. New operations can also be created and shared, making the tool increasingly more powerful. Finally, using a set of use cases, it’s possible to generate a web application that abstracts the RDF model where the data is represented, making it possible for lay users to access this information without any knowledge of the RDF model.

Full textAbstract:
Databases are present everywhere in our modern society and the amount of data that have to be stored is constantly increasing, which means that it’s now more important than ever to be able to handle massive data sets effectively. NoSQL databases2 were developed to solve this problem by efficiently storing large amounts of data and enable fast access to that data. Since NoSQL databases only became popular within the last ten years, they haven’t been as well researched as relational databases. An in-depth evaluation is carried out on six distinct features, where one part is comparative performance tests. The other features are: scalability, consistency, availability, durability and reliability. MongoDB and Oracle NoSQL are the NoSQL databases used and together with Oracle RDBMS as relational database make up the basis for a comparative study of the above mentioned features.The results showed that there are big differences between how data is handled in NoSQL compared to relational databases that will affect the choice of database, e.g. that NoSQL tends to prioritize that clients can reach the database over non-contradictory data and lowering the demands on transaction management to increase performance and storage capacity. Furthermore, the performance tests showed that both NoSQL databases performed beer than the relational database regardless of the data set size. MongoDB was clearly the fastest on reading operations, while Oracle NoSQL performed write operations the fastest most of the time. Both NoSQL databases are impacted less by a growing data set than the relational database for both read and write operations.

Full textAbstract:
Peatlands are important terrestrial stores ofcarbon and a principal source ofdissolved organic carbon (DOC) to the fluvial environment.. Whilst often regarded as a net carbon sink, enhanced DOC concentrations and an associated rise in the level of water discolouration observed in many artificially drained peatland catchments across Europe and North America suggests that continued degradation may shift the balance of the carbon budget, such that they become a net carbon source. Peatland restoration, in the form of drain blocking, is currently being undertaken in a number of these locations. However, a great deal of this work 'has been carried out on a pragmatic or even an ad-hoc basis, with a distinct lack of process-based assessment. Thus, very little is known about how such changes in land management affect DOC and colour dynamics.. In order to bridge this knowledge gap, this thesis examines a range of processes known to influence DOC/colour production and release. A variety of field monitoring and laboratory measurements were undertaken to assess the upland blanket peat within the Oughtershaw Beck catchment in the Yorkshire Dales National Park, UK. The installation of drainage ditches was found to reduce both the carbon storage potential of the peat and the quality of upland catchment waters. Drainage lowered the depth ofthe water table across the peat by an average of 10 em, enhanced the rate of microbial activity by 33 % and increased DOC and colour production in soil water solutions by 35 %, 'relative to an adjacent intact site that had not been drained. The greater level of aeration in the upper peat layers associated with a lowered water table also appeared to reduce the degree of surface saturation and the occurrence ·of overland flow (OLF), resulting in a greater volume of water being drawn down into the peat body. The reduced saturation levels caused the subsidence and compaction of the upper soil layers, which increased the bulk density and ultimately reduced the degree of macroporosity within the soil. ill turn, this is thought to have increased the residence time and surface area over which percolating waters flow, which is likely to have enhanced the degree of interaction with decompositional products, and thus the mobility of DOC/colour.

At the Uppsala Monitoring Centre (UMC), individual case safety reports (ICSRs) are managed, analyzed and processed for publishing statistics of adverse drug reactions. On top of the UMC’s ICSR database there is a data processing tool used to analyze the data. Unfortunately, there are some constraints limiting the current processing-tool along with that the amount of arriving data to be processed grows at a rapid rate. The UMC’s processing system must be improved in order to handle future demands. In order to improve performance various frameworks forparallelization can be used. In this work, the in-memory computing framework Sparkwas used for parallelization of one of the current data processing tasks. Local clusters for running the new implementation in parallel was also established.

Full textAbstract:
Sarcopenia is a disease of muscle wasting primarily seen in older adults. Although this term was first coined over three decades ago, there is a lack of consensus on a definition, screening criteria, and treatment protocol for sarcopenia. The primary purpose of this study is to determine whether registered dietitian nutritionists (RDNs) in the United States (U.S.) screen for sarcopenia. Study participants were recruited through a randomized email list and included RDNs throughout the U.S. Respondents completed a survey questioning knowledge of sarcopenia, screening tools and company protocols in place, and the need and desire for sarcopenia education. Data revealed a lack of pre-existing protocols in place, a dissonance of validated and unvalidated screening tools used in practice, and substantial need for sarcopenia education.

In Ussing-Kammer Messungen konnte eine insulinabhängige schnelle Steigerung des transepithelialen Natriumstroms gezeigt werden. Durch Western Blot-Untersuchungen sowie Inhibition spezifischer Kinasen wurden die intrazellulären Signaltransduktionsmechanismen der Insulin-induzierten Stimulation des Natriumtransports weiter charakterisiert. Es konnte eine Beteiligung der Phosphatidylinositol 3-Kinase, der Proteinkinase B, sowie von mTORC2 an den Signalwegen in den untersuchten Zellen nachgewiesen werden.
Ähnliche Wirkungen auf den Natriumtransport wie Insulin hatte der Wachstumsfaktor IGF-1. Somit wurde der akute Einfluss des Insulin/IGF-1 Systems auf den epithelialen Natriumtransport in fetalen Alveolarzellen charakterisiert.

La recherche de points communs entre des descriptions de données ou de connaissances est un problème de raisonnement fondamental en Machine Learning, qui a été formalisé par G. Plotkin dans les années 70s sous la forme du calcul du plus petit généralisant de ces descriptions. L'identification des plus petits généralisants a un large panel d'applications qui vont de l'optimisation de requêtes (e.g., pour matérialiser les points communs entre des requêtes lors de la sélection de vues ou pour factoriser leur exécution dans un contexte d'accès concurrentiel), à la recommandation dans le contexte des réseaux sociaux (e.g. pour créer de liens entre des utilisateurs basées sur leurs points communs selon leur profil ou leurs recherches). Dans cette thèse nous avons revisité la notion du plus petit généralisant dans le contexte de Resource Description Framework (RDF) et le fragment conjonctif de son langage de requêtes associé SPARQL, alias Basic Graph Pattern (BGP) queries. Contrairement à l'état de l'art, nous ne considérons aucune restriction, ni structurelle ni sémantique, sur les graphes et les requêtes. Nos contributions incluent la définition et le calcul des plus petits généralisants dans ces deux formalismes ce qui revient à trouver le plus grand ensemble de points communs entre des bases de données incomplètes et des requêtes conjonctives en présence de contraintes déductives. Nous proposons également une évaluation expérimentale de nos contributionsFinding commonalities between descriptions of data or knowledge is a fundamental task in Machine Learning. The formal notion characterizing precisely such commonalities is known as least general generalization of descriptions and was introduced by G. Plotkin in the early 70's, in First Order Logic. Identifying least general generalizations has a large scope of database applications ranging from query optimization (e.g., to share commonalities between queries in view selection or multi-query optimization), to recommendation in social networks (e.g., to establish connections between users based on their commonalities between proles or searches), through exploration (e.g., to classify/categorize datasets and to identify common social graph patterns between organizations (e.g., criminal ones)). In this thesis we revisit the notion of least general generalizations in the entire Resource Description Framework (RDF) and popular conjunctive fragment of SPARQL, a.k.a. Basic Graph Pattern (BGP) queries. By contrast to the literature, we do not restrict the structure nor semantics of RDF graphs and BGPQs. Our contributions include the denition and the computation of least general generalizations in these two settings, which amounts to nding the largest set of commonalities between incomplete databases and conjunctive queries, under deductive constraints. We also provide an experimental assessment of our technical contributions

Full textAbstract:
American Recommended Dietary Allowances (RDAs) and British Dietary Reference Values (DRVs) are used as the scientific benchmarks in a number of policies and surveys relating to food, nutrition and welfare. In the USA the RDAs have a number of statutory and regulatory involvements, particularly with respect to food assistance programmes and the definition of the poverty level. In the UK, although DRVs have no statutory role, they are the benchmarks against which diets of population groups are assessed or food supplies are determined, and hence they indirectly influence various policy decisions. Although RDAs and DRVs are often presented and used as if they were solely scientific standards, the thesis is premised upon the assumption that they are in fact a mixture of scientific, social and political factors. The thesis examines the way in which RDAs and DRVs are constructed, both the process and the products, by particular reference to the allowances for vitamin C in the USA and UK, and the controversy that surrounded the publication of the tenth edition of the RDAs in the USA in the 1980s. In particular, it focuses on what constitutes scientific evidence in the RDA arena, where and why boundaries are drawn between scientific and non-scientific evidence, and what are the judgements and interpretations included in the process and products of RDA and DRV construction. Research was carried out by means of a critical analysis of the literature to identify the relevant scientific evidence and areas of interpretation and selection. This was followed by in-depth interviews with key individuals who were involved in the most recent RDA and DRV report processes or in the disputed 1985 RDA report, or who have been advocates or critics of these standards over the years. The thesis shows that the science underlying the recommended figures is incomplete and the theoretical methods outlined for determining an RDA/DRV were not followed in practice. Even though the standards could be improved by strengthening the scientific evidence, they will always be subject to value judgements over the question of 'adequacy'. Influencing such judgements and also underlying the 1985 RDA controversy are the conflicting certainties and interests of different cognitive groups within science. With scientific credibility and scientific authority at stake, the boundary between science and non-science moves to suit the interests and beliefs of the different scientific groups. At the same time external groups align themselves with the cognitive evidence which reinforces their own position.

Full textAbstract:
Annotations play a key role in understanding and describing the data, and annotation management has become an integral component in most emerging applications such as scientific databases. Scientists need to exchange not only data but also their thoughts, comments and annotations on the data as well. Annotations represent comments, Lineage of data, description and much more. Therefore, several annotation management techniques have been proposed to efficiently and abstractly handle the annotations. However, with the increasing scale of collaboration and the extensive use of annotations among users and scientists, the number and size of the annotations may far exceed the size of the original data itself. However, current annotation management techniques don’t address large scale annotation management. In this work, we propose three chapters to that tackle the Big annotations from three different perspectives (1) User-Centric Annotation Propagation, (2) Proactive Annotation Management and (3) InsightNotes Summary-Based Querying. We capture users' preferences in profiles and personalizes the annotation propagation at query time by reporting the most relevant annotations (per tuple) for each user based on time plan. We provide three Time-Based plans, support static and dynamic profiles for each user. We support a proactive annotation management which suggests data tuples to be annotated in case new annotation has a reference to a data value and user doesn’t annotate the data precisely. Moreover, we provide an extension on the InsightNotes: Summary-Based Annotation Management in Relational Databases by adding query language that enable the user to query the annotation summaries and add predicates on the annotation summaries themselves. Our system is implemented inside PostgreSQL.

A Reserva de Desenvolvimento Sustentável (RDS) Itapanhapima e a Reserva Extrativista (RESEX) Taquari foram criadas na cidade de Cananeia, área litorânea do Vale do Ribeira no estado de São Paulo, como parte das Unidades de Conservação (UC´s) de uso sustentável que compõem o Mosaico de Unidades de Conservação do Jacupiranga (MOJAC), criado em 2008. Essas novas categorias de unidade de conservação de uso sustentável foram formuladas no âmbito dos debates que envolveram o Sistema Nacional de Unidades de Conservação (SNUC), a partir de uma visão socioambiental, ou seja, que busca aliar conservação da biodiversidade e da sociodiversidade. Dessa forma, a proposta do MOJAC tem como objetivo aliar proteção ambiental ao desenvolvimento sustentável, e permitir a permanência digna das populações reconhecidas como tradicionais em seus territórios de direito. A partir disso, este trabalho de pesquisa analisa o processo de implementação dessas novas categorias de unidades de conservação ambiental na área rural da cidade de Cananeia e os novos conflitos decorrentes dessa forma de intervenção governamental em áreas historicamente ocupadas. Tal análise foi feita sob a perspectiva das populações locais que, a partir desse contexto, passam a ser reconhecidas jurídica e politicamente como tradicionais. Para tanto foi elaborado um corpus documental por meio do registro das histórias de vida dos beneficiários destas unidades de conservação, segundo os procedimentos técnicos e analíticos da história oral.The Itapanhapima Sustainable Development Reserve (RDS) and the Taquari Extractive Reserve (RESEX) were created in the city of Cananeia, a coastal area of the Ribeira Valley in the state of São Paulo, as part of the Sustainable Conservation Units (UC´s) from a sustainable use which composes the Jacupiranga Conservation Units Mosaic (MOJAC) created in 2008. These new categories of conservation units for sustainable use were formulated in the context of the debates that involved the National System of Units Conservation (SNUC) from a socio-environmental perspective, that is, it seeks to combine biodiversity and socio diversity preservation. Therefore, the proposal of MOJAC aims to ally environmental protection to sustainable development and allow a worthy and dignified permanence for the populations recognized as traditional in their territories by rights. From this, this research work analyzes the implementation process of these new environmental units conservation categories in the rural area of the city of Cananeia and the new resulting conflicts from this form of governmental intervention in historically occupied areas. This analysis was done from the perspective of local populations that, from this context, are now legally and politically recognized as traditional. For this, a documentary corpus was elaborated through the recording of life histories of the beneficiaries of these conservation units, according to the technical and analytical procedures of oral history.

Previous issue date: 2007-02-28The objectives of this work were to analyze the language development of deaf children using a cochlear implant (CI) through a longitudinal study using the Reynell Developmental Language Scales (RDLS), to compare the performance of the deaf children to the performance of children with normal hearing, and to correlate it with the time of use of the CI. The participants were 17 6-year-old children with normal hearing and 9 deaf children using CI. The chronological age of the deaf children ranged from 4 to 8 years-old. The time of use of CI was, on average, 1 year 6 months at the 1st evaluation, 3 years 7 months at the 2nd evaluation, and 4 years 9 months at the 3rd evaluation. The deaf children were evaluated longitudinally through the RDLS, which is composed of the Verbal Comprehension Scale and Expressive Language Scale. The data were analyzed qualitatively and quantitatively. The implanted children showed progress of both their receptive and expressive abilities that were statistically significant but inferior to the children with normal hearing. In the verbal comprehension the differences between means and medians of scores of the deaf children and of the normal children were statistically significant. In the expressive language there was not a statistically significant difference. There was no correlation between the answers in both scales and the time of use of the CI for this group of deaf children, probably had to the reduced number of children of this group. The study proves the efficacy of the CI to the development of receptive and expressive language abilities and shows that the RDLS is effective in the longitudinal evaluation of deaf children using CI.

Os objetivos deste estudo foram analisar o desempenho da linguagem de crianças surdas usuárias de implante coclear (IC) por meio de um estudo longitudinal, utilizando-se a Reynell Developmental Language Scales (RDLS), comparar o desempenho das crianças surdas com o desempenho de crianças ouvintes e correlacioná-lo com o tempo de uso do IC. Os participantes foram 17 crianças ouvintes de 6 anos de idade e 9 crianças surdas usuárias de IC. A idade cronológica das crianças surdas variou entre 4 e 8 anos e o tempo de uso do IC foi, em média, 1 ano e 6 meses na 1ª avaliação, 3 anos e 7 meses na 2ª avaliação e 4 anos e 9 meses na 3ª avaliação. As crianças surdas foram avaliadas longitudinalmente por meio da RDLS, que é composta pelas Escalas de Compreensão e Expressão Verbal. Os dados foram analisados qualitativa e quantitativamente. Os resultados mostraram que as crianças implantadas obtiveram uma evolução significativa estatisticamente em relação às habilidades de linguagem receptiva e expressiva, todavia os resultados foram inferiores aos apresentados pelas crianças ouvintes. Para a compreensão verbal, a diferença entre as médias e medianas das crianças surdas e das crianças ouvintes foi significativa estatisticamente. Para a expressão verbal, porém, essa diferença não foi significativa. Não foi encontrada correlação entre as respostas de compreensão e expressão verbal e o tempo de uso do IC para este grupo de crianças surdas, devido provavelmente ao número reduzido de crianças deste grupo. O estudo comprova a efetividade do IC para o desenvolvimento das habilidades de linguagem receptiva e expressiva e demonstra que a RDLS é eficaz na avaliação longitudinal de crianças surdas usuárias de IC.

Full textAbstract:
RDM1 est un gène découvert récemment et impliqué dans la réponse cellulaire au cisplatine chez les vertébrés. Le gène RDM1 (pour RAD52 Motif 1) a été identifié, dans des bases de données, en cherchant des similarités avec RAD52. Nous avons par la suite identifié une protéine partenaire de RDM1, HP1α, un composant majeur de l'hétérochromatine et largement impliquée dans les mécanismes épigénétiques. Nous avons mis en évidence cette interaction en double-hybride chez la levure avec de nombreux mutants de RDM1 dans une région identifiée comme la "HP1 interaction box" ou "HPbox". Auparavant, nous avons réalisé la disruption de RDM1 dans des cellules de poulet ce qui conduit à une hypersensibilité des cellules au cisplatine quand les cellules sont traitées avec. De plus, nous avons démontré la liaison spécifique de RDM1 aux adduits cisplatine-ADN. Grâce à ces résultats, nous plaidons pour un rôle de RDM1 dans la résistance au cisplatine dans le traitement des cancers chez l'homme. Les lignées humaines de cancer du poumon représentent un bon modèle pour notre étude pour deux raisons : tout d'abord parce qu'un traitement à base de cisplatine constitue la chimiothérapie la plus efficace contre les cancers non à petites cellules (NSCLC) et ensuite parce que la résistance à ce même traitement augmente et que nous manquons de marqueurs moléculaires pour l'expliquer. Notre travail a montré 1) de fortes variations dans les niveaux d'expression de l'ARNm de RDM1 après une exposition au cisplatine et 2) une accumulation des adduits cisplatine-ADN alors que les cellules ont été traitées avec un shRNA dirigé contre RDM1. Pour conclure, nous avons ouvert un nouveau pan de recherche sur une protéïne qui reste mystérieuse, RDM1, mais qui pourrait être un nouveau facteur pronostic dans les cancers du poumon, même si la fonction exacte de RDM1 dans les cas de réparation de l'ADN suite à une exposition au cisplatine reste inconnueRDM1 is a novel gene involved in the celle response to cisplatin in vertebrates. The RDM1 gene (for RAD52 Motif 1) was identified while searching databases for sequences showing similarities to RAD52. We have identified a protein partner of RDM1, HP1α, a major component of the heterochromatin and largely involved in epigenetic mechanisms. We have shown this interaction in 2-hybrid assays with several mutants of RDM1 in a region we identified as the "HP1 interaction box" also named "HPbox". We have also shown that RDM1 can act a transcriptional repressor but needs, for a large part, the presence of the "HPbox". Previously we have shown that the knock-out of RDM1 in a chicken cell lines leads to a hypersensitivity to cisplatin when cells are treated with. In addition, we have demonstrated the specific binding of RDM1 on adducts formed by cisplatin and DNA. Based on theses evidences, we plead for a role of RDM1 in the resistance to cisplatin treatment in human cancers. Lung cancers cell lines represent a good model for this study for two main reasons : first, cisplatin-based combination treatment is the most effective chmotherapy for Non Small Cell Lung Cancer (NCLC), second, resistance to the treatment is increasing and we lack of molecular marker to explain it. Our worf has shown 1) strong variations in the expression level of the mRNA of RDM1 following a cisplatin treatment and 2) an accumulation of DNA-cisplatin adducts while the cells were treated with shRNA towards RDM1. In conclusion, we opened a new field of research on a protein which keeps a huge part of mystery, RDM1, but it might be a new prognostic factor in lung cancer, even if the exact function of RDM1 in the cases of DNA repair following cisplatin treatment remains unknown

Full textAbstract:
El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado.In the past decade, there has been an increasing need for semantic-aware data search and indexing in textual (structured and NoSQL) databases, as full-text search systems became available to non-experts where users have no knowledge about the data being searched and often formulate query keywords which are different from those used by the authors in indexing relevant documents, thus producing noisy and sometimes irrelevant results. In this paper, we address the problem of semantic-aware querying and provide a general framework for modeling and processing semantic-based keyword queries in textual databases, i.e., considering the lexical and semantic similarities/disparities when matching user query and data index terms. To do so, we design and construct a semantic-aware inverted index structure called SemIndex, extending the standard inverted index by constructing a tightly coupled inverted index graph that combines two main resources: a semantic network and a standard inverted index on a collection of textual data. We then provide a general keyword query model with specially tailored query processing algorithms built on top of SemIndex, in order to produce semantic-aware results, allowing the user to choose the results' semantic coverage and expressiveness based on her needs. To investigate the practicality and effectiveness of SemIndex, we discuss its physical design within a standard commercial RDBMS allowing to create, store, and query its graph structure, thus enabling the system to easily scale up and handle large volumes of data. We have conducted a battery of experiments to test the performance of SemIndex, evaluating its construction time, storage size, query processing time, and result quality, in comparison with legacy inverted index. Results highlight both the effectiveness and scalability of our approach.
This study is partly funded by the National Council for Scientific Research - Lebanon (CNRS-L), by the Lebanese American University (LAU), and the Research Support Foundation of the State of Sao Paulo ( FAPESP ). Appendix SemIndex Weighting Scheme We propose a set of weighting functions to assign weight scores to SemIndex entries, including: index nodes , index edges, data nodes , and data edges . The weighting functions are used to select and rank semantically relevant results w.r.t. the user's query (cf. SemIndex query processing in Section 5). Other weight functions could be later added to cater to the index designer's needs.

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, NevadaCreating a generic, multi-vendor data exchange system for transmitting telemetry configurations between various systems is a daunting task. To date many different systems have been proposed including relational databases (RDBMS), TMATS, and several different XML schemas. Although many of these systems have been implemented, a complete, flexible solution has not been developed. This paper describes an implementation that is currently in use for exporting and importing a complete telemetry system via XML. Using this system, an engineer can import an entire telemetry configuration, a partial telemetry configuration, or even just a single measurement (parameter). As a result, the gap between user database systems and the airborne instrumentation vendor’s configuration software (IVCS) is seamlessly bridged. This provides many benefits including: the ability to rapidly change configurations, data entry error avoidance, version control, the protection of sensitive information, and configuration reusability. This system allows for the configuration of all aspects of the telemetry setup including data acquisition hardware, transmitters, ground stations, and recorders. In addition, the recorder settings and the definition of the data that are to be recorded are coupled and linked to the rest of the telemetry configuration, which facilitates future data recovery.

Full textAbstract:
The Global Positioning System (Navstar-GPS) has modernized and allow greater ease in surveys related to activities that require placement in real time. This system consists of a constellation of satellites around the Earth providing a service for 24 hours three-dimensional positioning, velocity and time information to the users. However, certain atmospheric factors and other sources of error can affect the accuracy of GPS receivers. Thus, users can make more precise data collected with the Differential GPS (DGPS). It consists of a network of towers that receive the GPS signals and transmit the signals through fixed radio transmitters. It is effective to support activities which require continuous positioning in real time, which are required accuracies in the order of meters (1 to 3 m). In order for it be a medium to transmit the differential corrections, and the availability of this means there is not always easily and / or economic in Brazil, chose, for the development of this work, the RDS (Radio Data System) and NTRIP (Networked Transport of RTCM via Internet Protocol) for this purpose, using differential corrections transmitted by the format in its implementation DGPSBRDS simplified. It was analyzed statistically and compared it precision and accuracy or standard deviation or mean absolute deviation of the GPS positions with transmission of differential corrections in the RTCM (Radio Technical Commission for Maritime Services) with the surveys carried out by two systems: RDS and NTRIP. They also compared the methods of positioning, the absolute and differential. It was concluded that the differential positioning is obtained
more satisfactory results with estimates of precision ranged from 1 to 3 m. The system met the goals of precision and accuracy was NTRIP, which has enabled
coordinated in real time with greater accuracy.O Sistema de Posicionamento Global (NAVSTAR-GPS) veio modernizar e permitir maior facilidade nos levantamentos relacionados às atividades que necessitam de posicionamento em tempo real. Este sistema é formado por uma constelação de satélites que envolvem a Terra fornecendo um serviço de posicionamento tridimensional durante 24 horas, informação de velocidade e tempo para seus utilizadores. Entretanto, certos fatores atmosféricos e outras fontes de erro podem afetar a precisão de receptores GPS. Desta forma, os usuários podem tornar os dados coletados mais precisos com o GPS Diferencial (DGPS). Ele consiste em uma rede de torres que recebem os sinais GPS e transmitem os sinais corrigidos por meio de transmissores de rádio. É eficaz para apoiar atividades nas quais se requer um posicionamento contínuo, em tempo real, onde são necessárias acurácias na ordem do metro (1 a 3 m). Tendo em vista que para ele é necessário um meio de comunicação para transmitir as correções diferenciais, e que a disponibilidade deste meio nem sempre existe de forma fácil e/ou econômica no Brasil, escolheu-se, para o desenvolvimento deste trabalho, o RDS (Radio Data System) e o NTRIP (Networked Transport of RTCM via Internet Protocol) para tal finalidade, utilizando correções diferenciais transmitidas por meio do formato DGPSBRDS em sua implementação simplificada. Analisou-se estatisticamente e comparou-se precisão ou desvio padrão e acurácia ou média dos desvios absolutos de posicionamentos GPS com transmissão de correções diferenciais no formato RTCM (Radio Technical Commission for Maritime Services) com os levantamentos efetuados pelos dois sistemas: RDS e NTRIP. Também foram comparados os modos de posicionamento, o absoluto e o diferencial. Concluiu-se que pelo posicionamento diferencial obtêm-se resultados mais satisfatórios cuja estimativa de precisão variou de 1 a 3 m. O sistema que satisfez os objetivos de precisão e acurácia foi o NTRIP, o qual permitiu obter coordenadas em tempo real com maior precisão.

As estratégia atuais de desenvolvimento de produtos compartilham um requisito fundamental: a necessidade de ferramentas computacionais capazes de integrar e coodenar requisitos de projeto durante as atividades de modelamento de produtos. Vários estudo nesta área, apontam para a integração de feramentas de sistemas CAD comerciais com outras tecnologias de informação. Isso permite combinar e compartilhar de maneira centralizada, dados gerados por sistemas computacionai empregados nas diferentes áreas de conhecimento da empresa. O presente trabalho segue esta linha de pesquisa. Ele propõe uma abordagem para modelamento de peças mecânicas na fase de detalhamento de projeto, utilizando uma biblioteca com definições de features personalizadas. Tais definições são entendidas como unidades informacionais reusáveis de projeto, constituidas de dados geométricos e não geométricos. Elas são representadas através da combinação de recursos de sistemas CAD comerciais de médio ou grande porte, com RDBMS. O obejetivo é demonstrar pontencialidades e limitações na utilização das ferramentas disponíveis nestes sistemas CAD, para o desenvolvimento de aplicações baseadas na tecnologia de features. É apresentada uma revisão do estado da arte em sistemas CAD e RDBMS comerciais, descrição da abordagem proposta, e sua implementação prática. A abordagem proposta integra informações de engenharia no projeto mecânico para criação de modelos mais completos de peças e também facilita o compartilhamento destes dados. Portanto, ela pode ser usada como base de implementação de um ambiente computacional para Engenharia Simultânea. A reusabilidade de dados possibilita o trabalho com dados de projeto já otimizados, segundo considerações de manufaturabilidade, montabilidade, etc., favorecendo assim a padronização, redução de tempo e custo no desenvolvimento de produtos.

Full textAbstract:
Research Data Management (RDM) has received a lot of attention recently. In South Africa, the importance of RDM has amplified since the release of the National Research Foundation‟s (NRF) open access statement. According to the statement, researchers who receive funding from the NRF must deposit their research output in an open access (OA) repository. In addition, the data supporting the research should be deposited in an accredited OA repository with a Digital Object Identifier (DOI) for future citations (NRF, 2015: online). The mandate, along with other drivers such as research data re-use, increased impact and validation of research findings has forced institutions to investigate the possibility of offering RDM services in their institutions (Ashley, 2012).
It is expected that libraries and Library and Information Science (LIS) professionals will initiate and support RDM in their institutions. LIS professionals will need to upgrade or obtain new skills and knowledge to fulfil their new roles and responsibilities. Various training opportunities are available to interested professionals to improve their knowledge and skills related to RDM. These can be as simple as a workshop or as complex as a university degree.
The objective of this research was to identify and evaluate a RDM training intervention to determine whether the training intervention could enhance the knowledge and skills of LIS professionals in South African (SA) Higher Education Institutions (HEIs). An embedded research design was used to investigate whether an RDM workshop, hosted by the Network for Data and Information Curation Communities (NeDICC), could enhance the LIS professional‟s (participants) perception of their RDM understanding, knowledge and skills. The research found that the RDM workshop was highly successful in enhancing the participant‟s perception of their RDM understanding and knowledge. The RDM workshop was less successful in enhancing the participant‟s perception of their RDM skills.
It was recommended that LIS professionals (1) take advantage of the online RDM training material available to enhance their understanding and knowledge of RDM; (2) attend face-to-face training interventions to enhance or develop their RDM skills and (3) enrol in university level educational programmes to gain a qualification in RDM if they qualify. It was also recommended that institutions that provide RDM training should focus on specific aspects of RDM instead of offering a general overview. This research can be used to inspire larger studies or studies that compare two or more RDM training interventions.Mini Dissertation (MIT)--University of Pretoria, 2016.

Full textAbstract:
Nowadays, although MapReduce is applied to the parallel processing on big data, it has some limitations: for instance, lack of generic but efficient and richly functional primitive parallel methods, incapability of entering multiple input parameters on the entry of parallel methods, and inefficiency in the way of handling iterative algorithms. Spark and Stratosphere are developed to deal with (partly) the shortcoming of MapReduce. The goal of this thesis is to evaluate Spark and Stratosphere both from the point of view of theoretical programming model and practical execution on specified application algorithms. In the introductory section of comparative programming models, we mainly explore and compare the features of Spark and Stratosphere that overcome the limitation of MapReduce. After the comparison in theoretical programming model, we further evaluate their practical performance by running three different classes of applications and assessing usage of computing resources and execution time. It is concluded that Spark has promising features for iterative algorithms in theory but it may not achieve the expected performance improvement to run iterative applications if the amount of memory used for cached operations is close to the actual available memory in the cluster environment. In that case, the reason for the poor results in performance is because larger amount of memory participates in the caching operation and in turn, only a small amount memory is available for computing operations of actual algorithms. Stratosphere shows favorable characteristics as a general parallel computing framework, but it has no support for iterative algorithms and spends more computing resources than Spark for the same amount of work. In another aspect, applications based on Stratosphere can achieve benefits by manually setting compiler hints when developing the code, whereas Spark has no corresponding functionality.

Every cell contains several millions of diffusing and reacting biological molecules. The interactions between these molecules ultimately manifest themselves in all aspects of life, from the smallest bacterium to the largest whale. One of the greatest open scientific challenges is to understand how the microscopic chemistry determines the macroscopic biology. Key to this challenge is the development of mathematical and computational models of biochemistry with molecule-level detail, but which are sufficiently coarse to enable the study of large systems at the cell or organism scale. Two such models are in common usage: the reaction-diffusion master equation, and Brownian dynamics. These models are utterly different in both their history and in their approaches to chemical reactions and diffusion, but they both seek to address the same reaction-diffusion question. Here we make an in-depth study into the physical validity of these models under various biological conditions, determining when they can reliably be used. Taking each model in turn, we propose modifications to the models to better model the realities of the cellular environment, and to enable more efficient computational implementations. We use the models to make predictions about how and why cells behave the way they do, from mechanisms of self-organisation to noise reduction. We conclude that both models are extremely powerful tools for clarifying the details of the mysterious relationship between chemistry and biology.

Full textAbstract:
Aim of this diploma thesis is to map semantic features of CMS Drupal version 7. The goal of the first part of this work is to theoretically describe semantic web problematic and CMS Drupal. The second -- practical part of this work maps in details all the features of semantic web, which are supported by described CMS Drupal. These semantic features are mapped in two different points of views -- implementation and functional. Main contribution of this work is the method used to map these features. It's based on Drupal plugins code modification and revision in order to draw or demonstrate these features, which are not necessarily completely documented or functional. Furthermore all of these features are demonstrated on examples created as a part of this thesis. Finally the last part of this work compares these mapped features to similar CMS systems.

Within the project Maps without Barriers realized under Charta 77 Foundation - Barriers Account, in 2015 we intend to map accessibility of buildings and its premises from the perspective of people with limited mobility. We plan to inspect nearly 600 castles, palaces and other tourist attractions in the Czech Republic. The acquired data will be gathered and published as an on-line map in form of open and machine-readable data. It will also appear as Linked Open Data. However, the project will not end with mapping premises, the main objective is to provide a solid foundation for a unified database of accessibility of buildings and its premises. Negotiations with institutions and organizations interested in mapping are in progress and we try to offer them our project platform for publication of their data. The required RDFS vocabulary will be designed and carried out as part of this diploma thesis. It will be tested on the data from a number of forms describing existing objects. The data will be gathered by means of services designed in terms of this theses and provided for purchasers and users equally.

Este trabalho apresenta os resultados preliminares de levantamento arqueológico realizado na RDS Amanã, Estado do Amazonas. Situada na região do médio curso do rio Solimões e baixo Japurá, a RDS Amanã está na fase de preparo do seu plano de gestão. A respeito do Patrimônio Arqueológico existente na reserva Amanã 32 sítios arqueológicos formados por terra preta, cerâmica e material lítico polido foram identificados em etapas de levantamento realizadas entre 2006 e 2008. Levando em consideração o tamanho, densidade e variabilidade dos vestígios arqueológicos, assim como, a intensidade dos processos pós-deposicionais os sítios Boa Esperança e Bom Jesus do Baré foram escolhidos para realização de mapeamentos e escavação. O objetivo principal desse mestrado é apresentar o contexto arqueológico da reserva Amanã a partir de uma perspectiva comparativa com pesquisas arqueológicas que ocorrem em outros locais da Amazônia. Mais especificamente com a cronologia estabelecida para as ocupações ceramistas na Amazônia Central e áreas adjacentes, como Baixo Amazonas e médio Rio Caquetá/Japurá. A partir de dados relativos ao tamanho, composição, formato e estratigrafia dos sítios, assim como analise cerâmica e datações é formulada uma cronologia preliminar para o lago Amanã.The main goal of this dissertation is to introduce the archaeological context of the Amanã Sustainable Development Reserve, situated near the middle course of the Amazon and the lower course of the Japurá Rivers, in the state of Amazonas; its management plan is currently under preparation. This context is then compared to the archaeology of other areas of Amazonia. Preliminary results of the archaeological survey carried out between 2006 and 2008 will be presented, during which time 32 archaeological sites were identified. These are composed of anthropogenic dark earth, pottery and ground lithics. The Boa Esperança and Bom Jesus do Baré archaeological sites were selected for mapping and excavation due to their size, density and the variability of archaeological material they contain. An initial chronology for the Amanã Lake is put forward, based on data related to site size, composition, form and stratigraphy. This is then contrasted to ceramicist occupations identified in the Central Amazon and adjacent areas (the Lower Amazon and middle Caquetá/Japurá). Such a comparative approach is employed as a tool to allow the insertion of the Amanã Lake in the wider scenario, in this way allowing for a contribution to debates and discussions that are important to Amazonian Archaeology, such as the origin and dispersal of ceramic traditions. The data will further provide information to be utilized with local inhabitants for the future development of research, public archaeology and the reserve\'s management activities.

Previous issue date: 2016-12-02A Reserva de Desenvolvimento Sustentável (RDS) Municipal Piraquê-açu e Piraquê-mirim formada pelo sistema estuarino dos rios Piraquê-açu e Piraquê-mirim, localiza-se no município de Aracruz-ES. Os manguezais deste estuário são ambientes de grande importância para as comunidades que habitam seu entorno e vivem dos seus recursos. O caranguejo-uçá Ucides cordatus é considerado uma das espécies de maior abundância nos manguezais brasileiros. Apesar do caranguejo-uçá ser considerado espécie importante ao ecossistema manguezal e recurso de subsistência para várias comunidades tradicionais e indígenas, há a necessidade do desenvolvimento de constantes estudos sobre a população com o intuito de contribuir para o desenvolvimento das ações do Plano de Manejo da Reserva de Desenvolvimento Sustentável. Estudos pretéritos sobre o caranguejo-uçá no Estuário do rio Piraquê-açú, mostram importantes informações e indicam a necessidade de análises atuais que auxiliem as ações de sustentabilidade desta espécie, assegurando a manutenção dos estoques em níveis adequados. O presente estudo fez amostragens em 18 parcelas fixas (10 x 10m) em bosques de franja e bosques de bacia, no sistema estuarino do rio Piraquê-açu, durante a baixa-mar de sizígia. Foram contados os números de tocas abertas e fechadas, para obtenção de dados referentes ao período de ecdise e densidade da espécie. Foram avaliados os diâmetros das tocas, com intuito de estimar os tamanhos das carapaças dos indivíduos. A coleta de indivíduos foi aleatória e utilizada para obtenção da razão macho e fêmea. Também serão avaliados parâmetros ambientais como a salinidade da água das tocas, análise do sedimento quanto à quantidade de matéria orgânica e tamanho de partículas (granulometria).
