Full textAbstract:
This diploma thesis deals with the theme simulation models. It is separated to three parts: theoretic, a part describing a simulation program and a practical part. The opening part's role is to introduce to a reader the problem about simulation models, inform him about simulation project building and define some key words. The second part explains a work with simulation program Simprocess. In the third part the reader finds out, how to use theoretic knowledge. It is demonstrated on the simulation of the operations of the company Prádelna Lety. A goal of this part is to make a simulation model, which describes the reality and can solve the main problems identified in the beginning of this part. All of this is the object of the analysis. After that is possible to give some advises about improving the operations.

Runtime performance is essential for real time games, the faster a game can run the more features designers can put into the game to accomplish their vision.A popular architecture for video games is the Entity Component System architecture aimed to improve both object composition and performance. There are many tests for how this architecture performs under its optimal linear execution.This thesis presents a performance comparison of how several popular open-source Entity Component System libraries perform when fetching data from other entities during iteration. An object-oriented test is also done to compare against and verify if the known drawbacks of object-orientation can still be seen within these test cases. Our results show that doing a random lookup during iteration can cause magnitudes worse performance for Entity Component Systems.

Full textAbstract:
This thesis is the product of a knowledge acquisition effort, whose objective was to obtain information essential to the modelling and simulation of a robotically operated laboratory on board the forthcoming space station "Freedom." The information is represented using the system entity structure, a knowledge representation scheme that utilizes artificial intelligence concepts. The system entity structure details the design information and associated knowledge required for the intelligent autonomous operation of the space-based laboratory. The approach is proven to be very beneficial for organizing and displaying the vast amounts of information that constitute this intricate system design. Knowledge management, representation, and the nature of a future software implementation are also addressed.

Elsebai, A. "A rules based system for named entity recognition in modern standard Arabic." Thesis, University of Salford, 2009. http://usir.salford.ac.uk/14925/.
Full textAbstract:
The amount of textual information available electronically has made it difficult for many users to find and access the right information within acceptable time. Research communities in the natural language processing (NLP) field are developing tools and techniques to alleviate these problems and help users in exploiting these vast resources. These techniques include Information Retrieval (IR) and Information Extraction (IE). The work described in this thesis concerns IE and more specifically, named entity extraction in Arabic. The Arabic language is of significant interest to the NLP community mainly due to its political and economic significance, but also due to its interesting characteristics. Text usually contains all kinds of names such as person names, company names, city and country names, sports teams, chemicals and lots of other names from specific domains. These names are called Named Entities (NE) and Named Entity Recognition (NER), one of the main tasks of IE systems, seeks to locate and classify automatically these names into predefined categories. NER systems are developed for different applications and can be beneficial to other information management technologies as it can be built over an IR system or can be used as the base module of a Data Mining application. In this thesis we propose an efficient and effective framework for extracting Arabic NEs from text using a rule based approach. Our approach makes use of Arabic contextual and morphological information to extract named entities. The context is represented by means of words that are used as clues for each named entity type. Morphological information is used to detect the part of speech of each word given to the morphological analyzer. Subsequently we developed and implemented our rules in order to recognise each position of the named entity. Finally, our system implementation, evaluation metrics and experimental results are presented.

Full textAbstract:
Crohn’s disease is an inflammatory bowel disease that may involve any part of the gastrointestinal tract with a variety of extraintestinal features. A flare of Crohn’s disease may present as partial small bowel obstruction or peritonitis. Dehydration, infectious agents, and cigarette smoking are some of the factors linked to a relapse of Crohn’s disease. Plesimonas Shigelloides, a bacterium that belongs to the enterobacteriaceae group may rarely lead to a flare of Crohn’s disease. We describe the case of a 31-year-old male with Crohn’s disease who developed a flare triggered by Plesimonas Shigelloides infection presenting as partial small bowel obstruction with ileal narrowing, and regional lymphadenopathy that responded to immunosuppressants.

Alanazi, Saad. "A Named Entity Recognition system applied to Arabic text in the medical domain." Thesis, Staffordshire University, 2017. http://eprints.staffs.ac.uk/3129/.
Full textAbstract:
Currently, 30-35% of the global population uses the Internet. Furthermore, there is a rapidly increasing number of non-English language internet users, accompanied by an also increasing amount of unstructured text online. One area replete with underexploited online text is the Arabic medical domain, and one method that can be used to extract valuable data from Arabic medical texts is Named Entity Recognition (NER). NER is the process by which a system can automatically detect and categorise Named Entities (NE). NER has numerous applications in many domains, and medical texts are no exception. NER applied to the medical domain could assist in detection of patterns in medical records, allowing doctors to make better diagnoses and treatment decisions, enabling medical staff to quickly assess a patient's records and ensuring that patients are informed about their data, as just a few examples. However, all these applications would require a very high level of accuracy. To improve the accuracy of NER in this domain, new approaches need to be developed that are tailored to the types of named entities to be extracted and categorised. In an effort to solve this problem, this research applied Bayesian Belief Networks (BBN) to the process. BBN, a probabilistic model for prediction of random variables and their dependencies, can be used to detect and predict entities. The aim of this research is to apply BBN to the NER task to extract relevant medical entities such as disease names, symptoms, treatment methods, and diagnosis methods from modern Arabic texts in the medical domain. To achieve this aim, a new corpus related to the medical domain has been built and annotated. Our BBN approach achieved a 96.60% precision, 90.79% recall, and 93.60% F-measure for the disease entity, while for the treatment method entity, it achieved 69.33%, 70.99%, and 70.15% for precision, recall, and F-measure, respectively. For the diagnosis method and symptom categories, our system achieved 84.91% and 71.34%, respectively, for precision, 53.36% and 49.34%, respectively, for recall, and 65.53% and 58.33%, for F-measure, respectively. Our BBN strategy achieved good accuracy for NEs in the categories of disease and treatment method. However, the average word length of the other two NE categories observed, diagnosis method and symptom, may have had a negative effect on their accuracy. Overall, the application of BBN to Arabic medical NER is successful, but more development is needed to improve accuracy to a standard at which the results can be applied to real medical systems.

Chen, Cheng. "A system to support clerical review, correction and confirmation assertions in entity identity information management." Thesis, University of Arkansas at Little Rock, 2015. http://pqdtopen.proquest.com/#viewpdf?dispub=3711495.
Full textAbstract:
Clerical review of Entity Resolution(ER) is crucial for maintaining the entity identity integrity of an Entity Identity Information Management (EIIM) system. However, the clerical review process presents several problems. These problems include Entity Identity Structures (EIS) that are difficult to read and interpret, excessive time and effort to review large Identity Knowledgebase (IKB), and the duplication of effort in repeatedly reviewing the same EIS in same EIIM review cycle or across multiple review cycles. Although the original EIIM model envisioned and demonstrated the value of correction assertions, these are applied to correct errors after they have been found. The original EIIM design did not focus on the features needed to support the process of clerical review needed to find these errors.
The research presented here extends and enhances the original EIIM model in two very significant ways. The first is a design for a pair of confirmation assertions that complement the original set of correction assertions. The confirmation assertions confirm correct linking decisions so that they can be excluded from further clerical review. The second is a design and demonstration of a comprehensive visualization system that supports clerical review, and both correction and confirmation assertion configurations in EIIM. This dissertation also describes how the confirmation assertions and the new visualization system have been successfully integrated into the OYSTER open source EIIM framework.

Full textAbstract:
Translation of technical manuals is expensive, especially when a larger company needs to publish manuals for their whole product range in over 20 different languages. When a text segment (i.e. a phrase, sentence or paragraph) is manually translated, we would like to reuse these translated segments in future translation tasks. A translated segment is stored with its corresponding source language, often called a language pair in a Translation Memory System. A language pair in a Translation Memory represents a Translation Entry also known as a Translation Unit. During a translation, when a text segment in a source document matches a segment in the Translation Memory, available target languages in the Translation Unit will not require a human translation. The previously translated segment can be inserted into the target document. Such functionality is provided in the single source publishing software, Skribenta developed by Excosoft. Skribenta requires text segments in source documents to find an exact or a full match in the Translation Memory, in order to apply a translation to a target language. A full match can only be achieved if a source segment is stored in a standardized form, which requires manual tagging of entities, and often reoccurring words such as model names and product numbers. This thesis investigates different ways to improve and optimize a Translation Memory System. One way was to aid users with the work of manual tagging of entities, by developing Heuristic algorithms to approach the problem of Named Entity Recognition (NER). The evaluation results from the developed Heuristic algorithms were compared with the result from an off the shelf NER tool developed by Stanford. The results shows that the developed Heuristic algorithms is able to achieve a higher F-Measure compare to the Stanford NER, and may be a great initial step to aid Excosofts’ users to improve their Translation Memories.Översättning av tekniska manualer är väldigt kostsamt, speciellt när större organisationer behöver publicera produktmanualer för hela deras utbud till över 20 olika språk. När en text (t.ex. en fras, mening, paragraf) har blivit översatt så vill vi kunna återanvända den översatta texten i framtida översättningsprojekt och dokument. De översatta texterna lagras i ett översättningsminne (Translation Memory). Varje text lagras i sitt källspråk tillsammans med dess översättning på ett annat språk, så kallat målspråk. Dessa utgör då ett språkpar i ett översättningsminnessystem (Translation Memory System). Ett språkpar som lagras i ett översättningsminne utgör en Translation Entry även kallat Translation Unit. Om man hittar en matchning när man söker på källspråket efter en given textsträng i översättningsminnet, får man upp översättningar på alla möjliga målspråk för den givna textsträngen. Dessa kan i sin tur sättas in i måldokumentet. En sådan funktionalitet erbjuds i publicerings programvaran Skribenta, som har utvecklats av Excosoft. För att utföra en översättning till ett målspråk kräver Skribenta att text i källspråket hittar en exakt matchning eller en s.k. full match i översättningsminnet. En full match kan bara uppnås om en text finns lagrad i standardform. Detta kräver manuell taggning av entiteter och ofta förekommande ord som modellnamn och produktnummer. I denna uppsats undersöker jag hur man effektivt implementerar en optimering i ett översättningsminnessystem, bland annat genom att underlätta den manuella taggningen av entitier. Detta har gjorts genom olika Heuristiker som angriper problemet med Named Entity Recognition (NER). Resultat från de utvecklade Heuristikerna har jämförts med resultatet från det NER-verktyg som har utvecklats av Stanford. Resultaten visar att de Heuristiker som jag utvecklat uppnår ett högre F-Measure jämfört med Stanford NER och kan därför vara ett bra inledande steg för att hjälpa Excosofts användare att förbättra deras översättningsminnen.

Full textAbstract:
With the advent of Network-Centric Warfare (NCW) concepts, Command and Control (C2) Systems need efficient methods for communicating between heterogeneous systems. To extract or exchange various levels of information within the networks requires interoperability between human and machine as well as between machine and machine. This dissertation explores the Information Exchange Framework (IEF) concept of distributed data fusion sensor networks in Network-centric environments. It is used to synthesize integrative battlefield pictures by combining the Battle Management Language (BML) and System Entity Structure (SES) ontology framework for C2 systems. The SES is an ontology framework that can facilitate information exchange in a network environment. From the perspective of the SES framework, BML serves to express pragmatic frames, since it can specify the information desired by a consumer in an unambiguous way. This thesis formulates information exchange in the SES ontology via BML and defines novel pruning and transformation processes of the SES to extract and fuse data into higher level representations. This supports the interoperability between human users and other sensor systems. The efficacy of such data fusion and exchange is illustrated with several battlefield scenario examples.A second intercommunication issue between sensor systems is how to ensure efficient and effective message passing. This is studied by using Cursor-on-Target (CoT), an effort to standardize a battlefield data exchange format. CoT regulates only a few essential data types as standard and has a simple and efficient structure to hold a wide range of message formats used in dissimilar military enterprises. This thesis adopts the common message type into radar sensor networks to manage the target tracking problem in distributed sensor networks.To demonstrate the effectiveness of the proposed Information Exchange Framework for data fusion systems, we illustrate the approach in an air defense operation scenario using DEVS modeling and simulation. The examples depict basic air defense operation procedure. The demonstration shows that the information requested by a commander is delivered in the right way at the right time so that it can support agile decision making against threats.

Full textAbstract:
Marginal zone (MZ) lymphomas (MZLs) represent a group of lymphomas originating from B lymphocytes of the “marginal zone” which is the external part of the secondary lymphoid follicles. The WHO classifies MZL into 3 entities; extranodal MZL, splenic MZL and nodal MZL. Extranodal marginal zone lymphoma (EMZL) can arise in different tissues, including the stomach, salivary gland, lung, small bowel, thyroid, ocular adnexa and skin. We present a 25 years old female with a history of angioedema and chronic cutaneous eczema who developed an unusual EMZL. Patient presented with a history of rapidly enlarging skin nodule on her left elbow that had been present for almost one year. Over a period of 2-3 weeks she felt the nodule rapidly changed in size and shape. Excisional biopsy of the mass revealed a lymphoid infiltrate based in the reticular dermis and focally extending into the subcutaneous adipose tissue with formation of disrupted lymphoid follicles positive for CD20, CD23 and BCL2 but negative for CD10, Cyclin D1 and SOX11. Diagnosis was consistent with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma). Patient on presentation did not have any B symptoms other cutaneous lesions, lymphadenopathy or hepatosplenomegaly. PET scan revealed no evidence of abnormal uptake leading to a final Stage IE definition. Patient initiated definitive radiation therapy. EMZL accounts for 5 -10 % of non-Hodgkin lymphoma. It has been described often in organs that are normally devoid of germinal centers. It may arise in reactive lymphoid tissue induced by chronic inflammation in extranodal sites. Primary cutaneous marginal zone lymphoma (PCMZL) is associated with infectious etiologies such as Borrelia burgdorferi and less commonly with viral infections or in relation to autoimmune disorders. Autoimmune disorders, specifically Sjögren's syndrome is associated with a 30-fold increased risk of marginal zone lymphoma. Localized disease can be treated by local radiotherapy, intralesional injections or excision. Widespread skin disease is usually treated with a CD20 directed monoclonal antibody-Rituximab. Patients with PCMZL usually have an indolent clinical course. Extracutaneous dissemination of MALT Lymphoma is uncommon and happens in 6-8 % of patients. The 5 years overall survival is between 98-100%. Family physicians and dermatologists should have a high index of suspicion for this rare lymphoma subtype especially in patients with inflammatory chronic skin conditions and atopy.

With the rapid development of the Internet and the increase in the number of online users, there is a growing interest in commerce for SMEs. However, it remains a concern as how to precisely describe the small to medium companies in the field of SME enterprises. The goal of this thesis is to set a service-oriented matching model based on the study of existing enterprise matching models and data format. In this thesis, the author is going to address the model that is able to present E-commerce SMEs through three dimensions -- reputation, geographic information and enterprise type. The model would enable the buyers to find better target enterprises from the range of SMEs and at the same time allow SMEs to present more reliable and complete information to the buyers. The thesis is going to develop and evaluate the prototype based on the matching model.

Full textAbstract:
The data of different information systems is heterogeneous. As systems are being integrated, it’s necessary to bridge inconsistencies to reduce heterogenous data. To integrate heterogenous systems a mediator can be used. The mediator acts as a middle-layer for integrating systems, it handles transfers and translating of data between systems. A case study was conducted, developing a prototype of an integration mechanism for exchanging genealogical data, that used the mediator concept. Further, a genealogical system was developed to take use of the integration mechanism, integrating with a genealogy service. To test the reusability of the integration mechanism, a file import/export system and a system for exporting data from the genealogy service to a file was developed. The mechanism was based on the usage of a neutral entity model, that integrating systems could translate to. A neutralizing/de-neutralizing mechanism was used for the translating of the data between the neutral entity model, and a system specific entity model. The integration mechanism was added to the genealogy system as an addon. The integration mechanism was successful at integrating genealogy data. The outcomes included: The integration mechanism can be added as an addon to one or more systems being integrated. It was good to have a neutral entity model, together with a neutralizing/de-neutralizing mechanism.

Full textAbstract:
The source system is the real or virtual environment that we are interested in modeling. It is viewed as a source of observable data, in the form of time-indexed trajectories of variables. The data that has been gathered from observing or experimenting with a system is called the system behavior data base. The time indexed trajectories of variables provide an important clue to compose the DEVS (discrete event specification) model. Once event set is derived from the time indexed trajectories of variable, the DEVS model formalism can be extracted from the given event set. The process must not be a simple model generation but a meaningful model structuring of a request. The source data and query designed with SES are converted to XML Meta data by XML converting process. The SES serves as a compact representation for organizing all possible hierarchical composition of system so that it performs an important role to design the structural representation of query and source data to be saved. For the real data application, the model structuring with the US Climate Normals is introduced. Moreover, complex systems are able to be developed at different levels of resolution. When the huge size of source data in US Climate Normals are implemented for the DEVS model, the model complexity is unavoidable. This issue is dealt with the creation of the equivalent lumped model based on the concept of morphism. Two methods to define the resolution level are discussed, fixed and dynamic definition. Aggregation is also discussed as the one of approaches for the model abstraction. Finally, this paper will introduce the process to integrate the DEVSML(DEVS Modeling Language) engine with the DEVS model creation engine for the Web Service Oriented Architecture.

Full textAbstract:
Clinical study data is usually collected without knowing what kind of data is going to be collected in advance. In addition, all of the possible data points that can apply to a patient in any given clinical study is almost always a superset of the data points that are actually recorded for a given patient. As a result of this, clinical data resembles a set of sparse data with an evolving data schema. To help researchers at the Moffitt Cancer Center better manage clinical data, a tool was developed called GURU that uses the Entity Attribute Value model to handle sparse data and allow users to manage a database entity’s attributes without any changes to the database table definition. The Entity Attribute Value model’s read performance gets faster as the data gets sparser but it was observed to perform many times worse than a wide table if the attribute count is not sufficiently large. Ultimately, the design trades read performance for flexibility in the data schema.

Full textAbstract:
Depuis une dizaine d’années, on constate que les propriétés d’apprentissage inhérentes aux jeux-vidéo incitent de nombreux développeurs à explorer leur potentiel en tant que moyen d’expression pour des buts divers et innovateurs (sérieux). L’apprentissage est au cœur de l’expérience de jeu, mais il prend normalement place dans les domaines affectifs et psychomoteurs. Quand l’apprentissage cible un contenu sérieux, des designers cognitifs/pédagogiques doivent veiller à son effectivité dans le domaine cognitif. Dans des équipes éminemment multidisciplinaires (jeu, technologie, cognition et art), la compréhension et la communication sont indispensables pour une collaboration efficace dès la première étape de conception. Dans une approche génie logiciel, on s’intéresse aux activités (multidisciplinaires) du processus de développement plutôt qu’aux disciplines elles-mêmes, dans le but d’uniformiser et clarifier le domaine. Puis, nous proposons une fondation logicielle qui renforce ce modèle multidisciplinaire grâce à une approche d’underdesign qui favorise la création des espaces de design collaboratifs. Ainsi, Genome Engine peut être vu comme une infrastructure sociotechnique dirigée-donnée qui permet à des développeurs non-programmeurs, comme le game designer et éventuellement le designer cognitif, de participer activement dans la construction du design du produit, plutôt que de l’évaluer déjà en temps d’utilisation. Son architecture est fondée sur un style de système de systèmes d’entités, ce qui contribue à sa modularité, sa réutilisabilité et adaptabilité, ainsi qu’à fournir des abstractions qui favorisent la communication. Plusieurs projets réels nous ont permis de tester notre approcheFor the last ten years, we witness how the inherent learning properties of videogames entice several creators into exploring their potential as a medium of expression for diverse and innovative (serious) purposes. Learning is at the core of the play experience, but it usually takes place at the affective and psychomotor domains. When the learning targets the serious content, cognitive/instructional designers must ensure its effectiveness at the cognitive domain. In such eminently multidisciplinary teams (game, technology, cognition, art), understanding and communication are essential for an effective collaboration from the early stage of inception. In a software engineering approach, we focus on the (multidisciplinary) activities of the development process rather than the disciplines themselves, with the intent to uniform and clarify the field. Then, we propose a software foundation that reinforces this multidisciplinary model thanks to an underdesign approach that favors the creation of collaborative design workspaces. Thereby, Genome Engine can be considered as a data-driven sociotechnical infrastructure that provides non-programmer developers, such as game designers and eventually cognitive designers, with a means to actively participate in the construction of the product design, rather than evaluating it once in usage time. Its architecture is based on a component-based application framework with an entity system of systems runtime object model, which contributes to modularity, reuse and adaptability, as well as to provide familiar abstractions that ease communication. Our approach has been extensively evaluated with the development of several serious game projects

Hylock, Ray Hales. "Beyond relational: a database architecture and federated query optimization in a multi-modal healthcare environment." Diss., University of Iowa, 2013. https://ir.uiowa.edu/etd/2526.
Full textAbstract:
Over the past thirty years, clinical research has benefited substantially from the adoption of electronic medical record systems. As deployment has increased, so too has the number of researchers seeking to improve the overall analytical environment by way of tools and models. Although much work has been done, there are still many uninvestigated areas; two of which are explored in this dissertation.
The first pertains to the physical storage of the data itself. There are two generally accepted storage models: relational and entity-attribute-value (EAV). For clinical data, EAV systems are preferred due to their natural way of managing many-to-many relationships, sparse attributes, and dynamic processes along with minimal conversion effort and reduction in federation complexities. However, the relational database management systems on which they are implemented, are not intended to organize and retrieve data in this format; eroding their performance gains. To combat this effect, we present the foundation for an EAV Database Management System (EDBMS). We discuss data conversion methodologies, formulate the requisite metadata and partitioned type-sensing index structures, and provide detailed runtime and experimental analysis with five extant methods. Our results show that the prototype, EAVDB, reduces space and conversion requirements while enhancing overall query performance.
The second topic concerns query performance in a federated environment. One method used to decrease query execution time, is to pre-compute and store "beneficial" queries (views). The View Selection Problem (VSP) identifies these views subject to resource constraints. A federated model, however, has yet to be developed. In this dissertation, we submit three advances in view materialization. First, a more robust optimization function, the Minimum-Maintenance View Selection Problem (MMVSP), is derived by combining existing approaches. Second, the Federated View Selection Problem (FVSP), built upon the MMVSP, and federated data cube lattice are formalized. The FVSP allows for multiple querying nodes, partial and full materialization, and data propagation constriction. The latter two are shown to greatly reduce the overall number of valid solutions within the solution space and thus a novel, multi-tiered approach is given. Lastly, EAV materialization, which is introduced in this dissertation, is incorporated into an expanded, multi-modal variant of the FVSP. As models and heuristics for both the federated and EAV VSP, to the best of our knowledge, do not exist, this research defines two new branches of data warehouse optimization. Coupled with our EDBMS design, this dissertation confronts two main challenges associated with clinical data warehousing and federation.

Full textAbstract:
Denna uppsats ämnar belysa om det går att digitalisera den individuella studieplanen på en institution vid Uppsala universitet. Digitalisering anses vara en av de största trenderna som påverkar dagens samhälle och det har visats bidra till ökad tillgänglighet och effektivitet inom offentlig förvaltning. Vid Uppsala universitet finns det i dagsläget behov av ett digitalt system för hanteringen av den individuella studieplanen. Studieplanen hanteras för tillfället som ett papper i form av en PDF och upplevs enligt tidigare studier, som ett mindre bra planerings- och uppföljningsverktyg. Forskningsarbetet har utförts baserat på forskningsstrategin Design & creation. Resultatet av forskningsprocessen är en informationsmodell, en processmodell i olika nivåer, samt en databas. Dessa modeller och databas är baserade på tidigare forskning, befintliga dokument och empiriskt material från intervjuer. Tidigare forskning omfattar ett verktyg för digitalisering, problem med identifierare, samt forskning kring modellering. De befintliga dokumenten utgörs av en tidigare studie om den individuella studieplan, samt lagstiftning, riktlinjer och allmän information gällande denna studieplan. Intervjuerna genomfördes med 9 informanter som använder studieplanen i sin roll på Uppsala universitet. Modellerna och databasen har utvärderats i en kriteriebaserad intervju med ämnesexpert, samt i en teoribaserad utvärdering. Forskningsresultatet tyder på att det är möjligt att digitalisera studieplanen med hjälp av de framlagda modellerna och databasen. Dessa modeller och databas kan med viss modifikation användas för att bygga ett digitalt gränssnitt och ett fullständigt system för studieplanen.This thesis aims to illustrate whether it is possible to digitize the individual study plan at an institution at Uppsala university. Digitalization is considered one of the biggest trends that affects today’s society and it has been shown to contribute to increased accessibility and efficiency in public administration. Uppsala university has a need for a digital system for the individual study plan. It is currently handled as a paper in the form of a PDF and is perceived as an inferior planning and monitoring tool, according to previous studies. The research work has been carried out based on the research strategy Design & creation. The result of the research process is an information model, a process model at different levels and a database. These models and database are based on previous research, existing documents and empirical material from interviews. Previous research includes a tool for digitalization, problems regarding identifiers and research regarding modeling. The existing documents comprise a previous study of the ISP, legislation, guidelines and general information regarding the ISP. The interviews were conducted with 9 informants who use the study plan within their role at Uppsala university. The models and database have been evaluated in a criteria-based interview with a subject matter expert and in a theory-based evaluation. The research results indicate that it is possible to digitize the study plan using the presented models and database. These models and database can be used with slight modifications to build a digital interface and a complete system for the ISP.

This thesis deals with the very topical issue in the sphere of the expert activity, which is requested by the general public at the same time. It sets a task of improvement, or better to saythe simplification in the approach to the appraising of real estate, with the aid of systemic methodology. There is as an example of the correct application of systemic methodology in the preparation of a sample expert opinion used in real estate (apartment house) located in Brno – Starý Lískovec. The property in question is appraised in accordance with the assignment by using the systemic approachonly after the evaluation of the current situation in appraising and discussing systemic methodology. A systemic approach to the appraising of aproperty is appropriately chosen largely because it better ensures the indispensable fact that, in the case of the expert opinion made by an expert, it is practically impossible to omit those important requisites which are inextricably linked to the expert opinion.

Several decades ago, computer control systems known as Electric Control Units (ECUs) were introduced to the automotive industry. Mechanical hardware units have since then increasingly been replaced by computer controlled systems to manage complex tasks such as airbag, ABS, cruise control and so forth. This has lead to a massive increase of software functions and data which all needs to be managed. There are several tools and techniques for this, however, current tools and techniques for developing real-time embedded system are mostly focusing on software functions, not data. Those tools do not fully support developers to manage run-time data at design time. Furthermore, current tools do not focus on visualization of relationship among data items in the system. This thesis is a part of previous work named the Data Entity approach which prioritizes data management at the top level of development life cycle. Our main contribution is a tool that introduces a new way to intuitively explore run-time data items, which are produced and consumed by software components, utilized in the entire system. As a consequence, developers will achieve a better understanding of utilization of data items in the software system. This approach enables developers and system architects to avoid redundant data as well as finding and removing stale data from the system. The tool also allows us to analyze conflicts regarding run-time data items that might occur between software components at design time.A Data-Entity Approach for Component-Based Real-Time Embedded Systems Development

Performance is something that is always of concern when developing real-time 3D graphics applications. The way programs are made today with object-oriented programming has certain flaws that are rooted in the methodology itself. By exploring different programming paradigms we can eliminate some of these issues and find what is best for programming in different areas. Because real-time 3D applications need high performance the data-oriented design paradigm that makes the data the center of the application is experimented with. By using data-oriented design we can eliminate certain issues with object-oriented programming and deliver improved applications when it comes to performance, flexibility, and architecture. In this study, an experiment creating the same type of program with the help of different programming paradigms is made to compare the performance of the two. Some additional up- and downsides of the paradigms are also mentionedDet finns övrigt digitalt material (t.ex. film-, bild- eller ljudfiler) eller modeller/artefakter tillhörande examensarbetet som ska skickas till arkivet.

Full textAbstract:
Game engines process a lot of data under strict deadlines. Therefore, measures to increase performance are important in this area. Data-Oriented Design (DOD) promotes principles that are meant to increase performance by better cache utilization. The purpose of this thesis is to examine a selection of these principles to give a better understanding of how DOD affects CPU time and the rate of cache misses, with focus on the area of game development. More specifically, the principles examined are removal of run-time polymorphism, iteration over contiguous data, and lowering the amount of data in hot loops. Also, the Entity-Component-System pattern is examined, which is based upon DOD principles. The approach was to first present a theoretical background on the subject, and then to conduct tests by implementing a simulation of movement and collision detection utilizing said principles. The tests were written in C++ and executed on an Intel Core i7 4770k with no rendering. CPU time was measured in updated entities per μs, and cache utilization was measured in the form of cache miss rate. The results showed that the DOD principles did increase performance. Cache miss rate was also lower, with the exception of when removing run-time polymorphism. The conclusion is that Data-Oriented Design, used in game development, is likely to result in better performance, mostly as a result of better cache utilization.

Nors farmacinė paslauga yra reglamentuojama Lietuvos Respublikos Farmacijos įstatymu, Geros vaistinių praktikos nuostatomis ir kitais teisės aktais, Lietuvos ir kitų šalių praktika rodo, kad ne visada šių nuostatų pavyksta laikytis, be to, šių teisės aktų nuostatomis nėra reglamentuojama, kaip turėtų būti garantuojamas klientų individualių poreikių ir lūkesčių tenkinimas vaistinėse.

Full textAbstract:
Le pilotage centralisé traditionnel de système manufacturier n’est plus capable de répondre aux besoins du marché en termes d’attentes des clients, de la variété et du cycle de vie des produits. En particulier, l’émergence des systèmes Cyber-Physiques (CPS), vus comme des réseaux de composants physiques et informatiques en interaction, a impacté le pilotage central prédictif pour contrer les perturbations dans les actuelles caractéristiques dynamiques du marché. Par exemple, la modification urgente des besoins de l’entreprise est l’une des perturbations les plus communes qui impacte le planning central d’une manière significative. A l’heure actuelle, le pilotage distribué, pouvant être basé sur les systèmes multi-agent, permet d’améliorer la réactivité pour répondre à différents types de perturbations afin que celles-ci ne soient plus des facteurs contraignants le pilotage. Les travaux de cette thèse explorent la conception de nouveaux algorithmes de pilotage en se basant sur les approches d’interactions sociales, telles que la négociation ou la théorie du consensus). Ces algorithmes intègrent les avantages des actifs liés à l’industrie du futur et englobent différentes entités intelligentes et hétérogènes, ainsi que des systèmes à évènements discrets. Chaque agent peut avoir des capacités différentes, en termes d’évolution, d’apprentissage ou autre, permettant d’une manière globale d’obtenir des comportements émergeants qui s’adaptent dynamiquement aux perturbations rencontrées. Ainsi, chaque agent intelligent décide quand il transmet son état actuel à son voisinage et la décision locale dépend du comportement de l’état des agents. Afin de vérifier l’efficacité des algorithmes proposés (négociation et consensus), ceux-ci ont été modélisés et formulés en mettant en réseau toutes les entités intelligentes, le tout basé sur deux ateliers industriels. Les algorithmes ont ensuite été testés en simulation et d’une manière expérimentale sur la cellule flexible de production du plateau technique TRACILOGIS. Des comparaisons ont été faites avec l’algorithme réactif actuellement implémenté sur cette plateforme, afin de montrer l’applicabilité des algorithmes dans l’obtention de ré-ordonnancement et re-séquencement de produits par priorité. Par conséquent, les résultats expérimentaux réalisés sur TRACILOGIS ont montré que les algorithmes de négociation et de consensus ont minimisé l’impact des perturbations en obtenant de meilleures performances globales qu’auparavantThe use of traditionally centralized control system does not able to meet the rapidly changing customer expectations, high product varieties, and shorter product life-cycles. In particular, the emergence of Cyber Physical System (CPS) which can be seen as interacting networks of physical and computational components has provided the foundation for many new factories’ infrastructures and improved the quality of products and processes. This Cyber Physical System has dramatically impacted the centrally predictive control system in responding to perturbation(s) in the current dynamic market characteristics. Urgent change for example is one of the common perturbations and has significant perturbing ability to a central predictive control system. Accordingly, it is now accepted that using agent-based control system improves the reactivity to treat these perturbation(s) until they are no longer limiting factors. In this study, the use of human-inspired interaction approach (by means of negotiation and consensus-based decision-making algorithms) is explored to design and propose a new control system. It has taken advantages from Industry 4.0 assets and encompassed heterogeneous and intelligent entities (mainly the product entities and resource entities) and discrete event systems. Each entity could have different capability (evolution, learning, etc.) and the whole physical and control system may lead emerging behaviors to dynamically adapt the perturbation(s). Hence, every intelligent entity decides when to broadcast its current state to neighbor entities and the controlling decision depends on the behavior of this state. The negotiation and consensus-based decision-making algorithms were initially formulated and modeled by networking all the contributing and heterogeneous entities considering two real industrial shop floors. Then after, simulation and application implementation tests on the basis of full-sized academic platform called TRACILOGIS platform have been conducted to verify and validate these decision-making algorithms. This has been done with expectations that the applicability of these algorithms will be more adaptable to set best priority-based product sequencing and rescheduling than another decision-making approach called pure reactive control approach. Accordingly, the experimental results have shown that the negotiation and consensus among the decisional entities have significantly minimized the impact of perturbation(s) on a production process launched on the TRACILOGIS platform. Meanwhile, using these two decision-making algorithms has conveyed better global performance (e.g., minimized makespan) over the pure reactive control approach

Full textAbstract:
The California state legislature introduces approximately 5,000 new bills each legislative session. While the legislative hearings are recorded on video, the recordings are not easily accessible to the public. The lack of official transcripts or summaries also increases the effort required to gain meaningful insight from those recordings. Therefore, the news media and the general population are largely oblivious to what transpires during legislative sessions.
Digital Democracy, a project started by the Cal Poly Institute for Advanced Technology and Public Policy, is an online platform created to bring transparency to the California legislature. It features a searchable database of state legislative committee hearings, with each hearing accompanied by a transcript that was generated by an internal transcription tool.
This thesis presents SKEWER, a pipeline for building a spoken-word knowledge graph from those transcripts. SKEWER utilizes a number of natural language processing tools to extract named entities, phrases, and sentiments from the transcript texts and aggregates the results of those tools into a graph database. The resulting graph can be queried to discover knowledge regarding the positions of legislators, lobbyists, and the general public towards specific bills or topics, and how those positions are expressed in committee hearings. Several case studies are presented to illustrate the new knowledge that can be acquired from the knowledge graph.

Full textAbstract:
One problem that exists in today's document management arena is the issue of retrieving information from electronic documents such as images, Microsoft Office documents, and e-mail. Specific data entities must be extracted from these documents so that the data can be searched and queried. This study presents a unique approach to extracting these entities: using Extensible Stylesheet Language Transformations (XSLT) to match patterns in text. Because XSLT is processed at run time, new XSLT templates can be created and used without having to recompile and redeploy the application. The specific implementation addressed in this project extracts entities from an image file. The data in the image file is converted to Extensible Markup Language (XML) text via optical character recognition (OCR), and then this XML text is transformed into an organized, well-formed XML output file using an XSLT template. We show this approach can accurately retrieve the correct data and this method can be extended to other electronic document sources.

We live in the Information Age. The effective use of information to manage organizational resources is the key to an organization's competitive power. Thus, a database plays a major role in the Information Age. A well designed database contains relevant, nonredundant, and consistent data. However, a well designed database is rarely achieved in practice. One major reason for this problem is the lack of effective support for logical database design. Since the late 1980s, various methodologies for database design have been introduced, based on the relational model, the functional model, the semantic database model, and the entity structure model. They all have, however, a common drawback: the successful design of database systems requires the experience, skills, and competence of a database analyst/designer. Unfortunately, such database analyst/designers are a scarce resource in organizations. The Structured Entity Model (SEM) method, as an alternative diagrammatic method developed by this research, facilitates the logical design phases of database system development. Because of the hierarchical structure and decomposition constructs of SEM, it can help a novice designer in performing top-down structured analysis and design of databases. SEM also achieves high semantic expressiveness by using a frame representation for entities and three general association categories (aspect, specialization, and multiple decomposition) for relationships. This also enables SEM to have high potential as a knowledge representation scheme for an integrated heterogeneous database system. Unlike most methods, the SEM method does not require designers to have knowledge of normalization theory in order to design a logical database. Thus, an end-user will be able to complete logical database design successfully using this approach. In this research, existing data models used for a logical database design were first studied. Second, the framework of SEM and the design approach using SEM were described and then compared with other data models and their use. Third, the effectiveness of the SEM method was validated in two experiments using novice designers and by a case analysis. In the final chapter of this dissertation, future research directions, such as the design of a logical database design expert system based on the SEM method and applications of this approach to other problems, such as the problems in integration of multiple databases and in an intelligent mail system, are discussed.

This bachelor thesis examines design implementation and differences between game entity systems, with a focus on a component-based structure. How each will affect the other will be discussed from both a technical and design point of view, including possible drawbacks or advantages regarding game design iteration and performance. Since the focus is on component-based entity systems, a clarification on traditional entity systems are required, thus this thesis focuses on entity systems that are traditional, property-based, container-based, and aggravated component-based. The design and implementation of each system was founded from different generations of programming paradigms which resulted in specific compositional structure based on each specific era of hardware configuration. This thesis analyses the progress of hardware alongside game entity system design to further understand its progression and evolution into today’s standards and implementation. Details on each system is provided from a design perspective for the traditional entity system and with an in-depth view for the component-based entity systems.

The goal of this thesis is to produce a generic database system for an IT-company calledNinetech. In this context generic means the database system can accept any input, withinreason, without one having to create a specific database schema beforehand. The prototypewill consist of a database, web service and a dynamic-link library. The three aforementionedcomponent’s design and function will be explained in chapter 2, alongside with the difficul-ties surrounding manipulating arbitrary data. The prototype’s performance is evaluated inchapter 3 and conclusions are drawn in chapter 4.

This diploma thesis covers the design and implementation of changes and extension modules of a chosen information system, used in JUDr. Ján Bartánus's attorney office in Ružomberok. The system, implemented as a web application based on the Symfony framework, is dedicated to the simplyfing, monitoring and organization of the work processes in a generic attorney office located in the Slovak Republic. For the purposes of a correct design, the thesis contains an analysis of the current state of the given attorney office, the environment in which it operates, its information system and existing solutions. Tools that were used to conduct the analysis were the SLEPT method, Porter's five forces, model 7S and SWOT matrix. Based on the results of the analyses, a change of the system has been designed, which entails an upgrade of the system, its user interface, integration of the register of companies of Slovak Republic and an extension module intended for the financial valuation of work performed by an attorney. The application has been developed utilizing the PHP and JavaScript programming language. The valuation module integrates the Google Maps API. The stability and speed of the system were tested by functional tests and profiling of the duration of HTTP requests. The main contribution of this thesis is the design and implementation of an extension of the information system, which can be used in any arbitrary attorney office situated in the Slovak Republic, and its practical application in the chosen company. This thesis builds on a previous thesis dedicated to the design and implementation of the information system, which is being extended in this diploma thesis.

Approved for public release; distribution is unlimitedCurrent modeling and simulation techniques may not adequately represent military operations using unmanned aircraft systems (UAS). A method to represent these conditions in a combat model can offer insight to the use and application of UAS operations, as well as understanding the sensitivity of simulation outcomes to the variability of UAS performance. Additionally, using combat model simulations that do not represent UAS behavior and conditions that cause this variability may return misleading or incomplete results. Current approaches include explicit scripting of behaviors and events. We develop a proof of principle search, targeting, and acquisition (STA) model for use with UAS within COMBATXXI, leveraging existing STA research conducted at the MOVES Institute at the Naval Postgraduate School. These dynamic behaviors are driven by events as they unfold during the simulation run rather than relying on preplanned events as in the scripted approach. This allows these behaviors to be highly reusable since they do not contain scenario or incident specific information. We demonstrate the application of the new STA model in a tactical convoy scenario in COMBATXXI. A design of experiments and post analysis quantifies the sensitivity of the measures of effectiveness of success to conditions contributing to variability in UAS performance.

Approved for public release; distribution is unlimitedThe Navy requires a capability for effective and efficient entry control for restricted areas that house critical assets. This thesis describes an Advanced Restricted Area Entry Control System (ARAECS) to meet this requirement. System requirements were obtained from existing governing documentation as well as stakeholder inputs. A functional architecture was developed and then modeled using the Imagine That Inc. ExtendSim tool. Factors affecting ARAECS operation were binned into physical, technology, Concept of Operations (CONOPS), and noise. An Overall Measure of Effectiveness was developed and a Design of Experiments (DOE) was conducted to measure the affects of these factors on ARAECS performance. The two main drivers were minimizing security violations while also maximizing personnel and vehicle throughput. Based on the modeling, an architecture was selected that best met system objectives—this architecture relied on the ability to pre-screen 40% of the workforce based on security clearance and thus subject them to reduced random screening. The architecture was documented using the Vitech CORE tool, and use cases were developed and documented. A test and evaluation plan was developed and discussed. Risk was then examined, including technical, schedule, and cost risks.
