基於網路服務的共享資料規格管理機制 / Mechanisms for Managing the Specifications of Web-Based Data Sharing Services

楊劍銘, Yang, Jang Ming Unknown Date (has links)
大型政府機關或企業,由於服務範圍廣大,應用系統繁多,各系統間不時有資料共享的需求(如各系統須使用人資系統)。但對於這些共享資料的管理上,常常因缺乏有效的機制與流程,而一直有無法同步或同步上資訊不一致的困擾。本研究提供一套中央控管規格機制,以管理面和技術面雙管齊下來解決此問題。本研究認為統一資訊必需先從統一資料規格(Data Specification)做起,同時訂定單一資料的提供來源及多個資料使用對象。 本研究利用Web Service WDSL語言特性作為制訂資料規格的依據。WSDL本身即是可自我描述的一種資訊規格,並具有跨平台的特性,以利各使用不同程式語言開發之系統進行整合。本研究認為既然共享資訊是一種共用行為,理當有一資訊規格維護者負責制訂維護管理規格,同時定期召開共享資訊制訂會議討論共享資訊範圍,本研究所設計之系統藉由資訊規格維護者,訂定WSDL共享資訊規格,供資訊提供者實作,並經由發表給各系統開發單位使用。本研究已實作一個工具來產生WSDL。 本研究期藉由集中控管資料規格的共享服務方法,定義各系統開發者的角色與責任,以治理源頭的方式,讓系統整合或資料交換更為容易,開發時程可以縮短,節省系統開發成本,讓有意參與政府機關的廠商不會怯步,讓機關招商更為容易。 / For the wide range of services and diversified application systems in operation in large government agencies or businesses, information sharing among systems is becoming increasingly necessary (such as users’ personal data on different systems). When it comes to managing shared information, lacking an effective system and flow process makes synchronized operation or access to information a less successful task. The research in question brings up a centralized control specification as solution to the issue through sound management and technique. In the research, uniform information starts from uniform data specification. At the same time, a single data source is set together with a plurality of data destinations. In the research in question, information specification is made based on Web Service WDSL language characteristics. WSDL refers to a kind of self-descriptive information specification that is operational across different platforms for successful integration of systems developed in different program languages. In this research, it is believed, since information sharing is a common behavior; there must be an information specification guard responsible for the scheming, maintenance and management of the same. On the other hand, regular meetings on information sharing must be convened for discussion of the scope. In the system made available in this research, the information specification guard makes the WSDL information sharing specification for operation by information providers and use by the system developers once publicized.We also Implement a tool to generate WSDL. In this research, it is expected, through the centralized managament of the specifications for shared services, the system developers could have their roles and responsibilities properly defined. By means of sorting out the sources, system integration or data exchange could become much easier and development could become successful more rapidly as a way to reduce the cost involved in system development and eventually, allow those who are willing to bid in public projects come to participate without much concern. If so, bidding by private sector could be an easy task.

Synchronization analysis and simulation of a standard IEEE 802.11g OFDM signal

Lowham, Keith D. 03 1900 (has links)
Approved for public release, distribution is unlimited / Synchronization of orthogonal frequency-division multiplexed (OFDM) signals is significantly more difficult than synchronization of a single-carrier system. The recently approved IEEE Standard 802.11g specifies a packet-based OFDM system that provides a basis for the discussion of OFDM synchronization in a packet-based environment. Algorithms that synchronize the receiver carrier demodulation frequency and phase, the data frame, the OFDM symbol timing, and the data symbol timing are discussed and analyzed in an AWGN channel. System View simulation is used to implement the frame and carrier frequency synchronization algorithms, where the performance of these algorithms is analyzed and they are shown to be useful detection algorithms for Standard 802.11g signal reception. / Lieutenant Commander, United States Navy

U.S. Coast Guard reorganization: why merging the field units is not enough to remain Semper Paratus (always ready) / United States Coast Guard reorganization

Greene, Lawrence E. 03 1900 (has links)
Approved for public release, distribution is unlimited / After the terrorist attacks of September 11, 2001, the U.S. Coast Guard shifted much of its effort toward Maritime Homeland Security activities. In response to this major shift in mission priorities, the Coast Guard is merging its Operational and Marine Safety field units into Sector commands. This reorganization is designed to ensure unity of effort, allow more efficient use of resources, improve training of Coast Guard members, and ensure better customer service. This thesis shows that further reorganization will be necessary at the operational and strategic levels of the Coast Guard. The organization-wide changes recommended by the author will allow the Coast Guard to align with the new Sector field commands, better align with the other agencies within the Department of Homeland Security, and ensure the critical tenets of unity of command, unity of direction, and unity of accountability are realized. Research data gathered for this project included surveys, personal interviews, and a use-case. The author also conducted a detailed review of documents produced at a Coast Guard Reorganization Summit, other internal Coast Guard documents, and the published literature. Based on the results of this study, the author offers 10 recommendations for the leaders of the post-9/11 Coast Guard. / Lieutenant Commander, United States Coast Guard

Analýza vybraných antropomotorických ukazatelů vojáků Hradní stráže / Analysis of specific anthropomotoric indicators of the Castle guard soldiers

Procházka, Josef January 2012 (has links)
The work deals with the analysis of selected anthropomotorics indicators members of the military unit of the Castle Guard. These indicators are: skin thickness measured at four part in the body posture and the level of performance in the annual examination of physical training. Is complemented by a survey, investigating the relationship of soldiers to physical activity. The theoretical part describes the military department of the Castle Guard, measurement of skin fold thickness, posture assessment, but also the structure and content of the physical training of the Army of the Czech Republic. The practical part contains a methodical workflow and finally analyzes the data Based on the analysis results we developed recommendations for managers concerning the components of physical performance which should be focused on in the training lessons. The results show that most of the soldiers are in the normal range (average) values of subcutaneous fat. Nevertheless, more than 10% of soldiers were found above- average amount of fat in the subcutaneous layer. Posture has almost 90% of the tested men was good, but the horizontal axis misalignment arms was confirmed in 78% of tested men. Changes in assessment disciplines annual examination of physical training in 2011 may also be the cause of the distribution...

"The War Comes First": Lt. Col. Francis Carroll Grevemberg and the Development of a World War II Antiaircraft Artillery Officer

Janous, Robert 14 May 2010 (has links)
This thesis deals with the life and career and intimate life of Francis Carroll Grevemberg, an antiaircraft World War II officer from New Orleans, Louisiana. Grevemberg joined the Louisiana National Guard in 1932 and began his military career in the midst of the Great Depression. In the reorganization of the U.S. Army before World War II, the War Department transformed Grevemberg's cavalry regiment into a coastal artillery battalion with antiaircraft capability. During World War II, Grevemberg saw continuous action in the North Africa, Italy and Southern France. He regularly wrote letters from battlefields to his wife Dorothy. These letters provide a important window into a young officer's feelings, thoughts and affection in the unfolding of World War II. They are documents of a soldier's emotional release during times of crises. Lt. Col. Grevemberg is a rare, World War II antiaircraft artillery officer who took part and survived five amphibious landings in the Mediterranean.

Säkerhets- och kostnadsjämförelse för maskinskydd kring balningslinje : En jämförelse av förreglingsbrytare

Viksten, Henrik January 2019 (has links)
Många arbetsrelaterade olyckor sker av att säkerhet kring att LOTO-principen är undermålig och att maskiners rörliga delar är lätt att komma åt. Vid konstruktion av en maskin är det viktigt att ta hänsyn till maskinens farliga upphov. För att konstruera bort detta är det viktigt redan på ett konstruktionsstadie att identifiera och bygga bort dessa områden med till exempel ett maskinskydd kring maskiner. Tillträdesplatser måste vara noga övervakad för att det ska vara en säker användning av maskin enligt maskindirektivet 2006/42/EG. I denna rapport har säkerhet såväl som kostnader setts över för en befintlig förreglingsbrytare på tillträdesplatser för en balningslinje och undersökt om kostnader kan minskas med föreslagen PROFInet baserat förreglingsbrytare. Den harmoniserade standarden EN ISO 13849-1:2016 tar upp ett sätt för att utvärdera säkerheten kring en maskins styrsystem allt utvärderas efter begreppet PL, Performance Level. För att räkna ut PL vid säkerhetsjämförelse användes SiSteMa och för att räkna ut kostnaden av dem olika alternativen emellan har en intervju kring kostnader gjorts och presenterats som en kvot. Säkerhetsjämförelse visar att PLd är bibehållen. Kostnadsjämförelsen visar att den föreslagna lösningen är dyrare än den befintliga men att en undermålig prisuppskattning kan ligga bakom detta. En aspekt av den nya förreglingsbrytaren som inte sågs över i rapporten men värt att nämna i slutsatsen kring säkerhets- och kostnadsjämförelse är att det föreslagna förreglingsbrytaren med PROFInet är en flexibel lösning med enkel felsökning. Framtida arbeten kring säkerhet vid balningslinje hade varit att titta på resterande tillträdesplatser som övervakas av ljusbomar och se om kostnader går att få ner där. / Many work-related accidents occur because safety around the LOTO principle is substandard and that the moving parts of machines are easy to access. When designing a machine, it is important to consider the machine's dangerous origin. To design this, it is important to identify and build these areas already at a design stage with, for example, a fence around machines. Access places must be carefully monitored for safe machine use according to the Machinery Directive 2006/42 / EC. In this report, safety as well as costs have been considered to an existing guard lock on access places for a baling line and examined whether costs can be reduced with the proposed PROFInet based guard lock. The harmonized standard EN ISO 13849-1: 2016 addresses one way of evaluating the safety of a machine's control system, all being evaluated according to the concept of PL, Performance Level. To calculate PL when comparing safety, SiSteMa was used and to calculate the cost of their different alternatives, an interview on costs has been made and presented as a quota. Safety comparison shows that PLd is retained. The cost comparison shows that the proposed solution is more expensive than the existing solution, but that a substandard price estimate may be behind this. One aspect of the new guard lock that was not seen in the report but worth mentioning in the conclusion about safety and cost comparison is that the proposed guard lock with PROFInet is a flexible solution with simple troubleshooting. Future work on safety at baling line would have been to look at remaining access places that are monitored by light curtains and see if costs can be reduced there.

Étude des détecteurs planaires pixels durcis aux radiations pour la mise à jour du détecteur de vertex d'ATLAS / Study of planar pixel sensors hardened to radiations for the upgrade of the ATLAS vertex detector

Benoit, Mathieu 10 June 2011 (has links)
Le Large Hadron Collider (LHC), située au CERN, Genève, produit des collisions de protons accélérés à une énergie de 3.5 TeV depuis le 23 Novembre 2009. L’expérience ATLAS enregistre depuis des données et poursuit sa recherche de nouvelle physique à travers l’analyse de la cinématique des événements issues des collisions. L’augmentation prévue de la luminosité sur la période s’étalant de 2011 2020 apportera de nouveaux défis pour le détecteur qui doivent être considérés pour maintenir les bonnes performance de la configuration actuelle. Le détecteur interne sera le sous-détecteur le plus affecté par l’augmentation de la luminosité qui se traduira par une augmentation des dommages occasionnés par la forte radiation et par la multiplication du nombre de traces associées à chaque croisement de faisceau. Les dommages causés par l’irradiation intense entrainera une perte d’efficacité de détection et une réduction du nombre de canaux actifs. Un intense effort de Recherche et Développement (R&D) est présentement en cours pour concevoir un nouveau détecteur pixel plus tolérant aux radiations et au cumul des événements générant un grand nombre de traces à reconstruire. Un premier projet de mise-à-jour du détecteur interne, nommé Insertable B-Layer (IBL) consiste à ajouter un couche de détection entre le tube à vide du faisceau et la première couche de silicium. Le projet SLHC prévoit de remplacer l’ensemble du détecteur interne par une version améliorée plus tolérante aux radiations et aux cumuls des événements. Dans cet ouvrage, je présente une étude utilisant la simulation technologique assisté par ordinateur (TCAD) portant sur les méthodes de conception des détecteurs pixels planaires permettant de réduire les zones inactives des détecteurs et d’augmenter leurs tolérances aux radiations. Les différents modèles physiques disponible ont étés étudiés pour développer un modèle cohérent capablede prédire le fonctionnement des détecteurs pixels planaires après irradiation. La structure d’anneaux de gardes utilisée dans le détecteur interne actuel a été étudié pour obtenir de l’information sur les possible méthodes permettant de réduire l’étendu de la surface occupée par cette structure tout en conservant un fonctionnement stable tout au long de la vie du détecteur dans l’expérience ATLAS. Une campagne de mesures sur des structures pixels fut organisée pour comparer les résultats obtenue grâce à la simulation avec le comportement des structures réelles. Les paramètres de fabrication ainsi que le comportement électrique ont été mesurés et comparés aux simulations pour valider et calibrer le modèle de simulation TCAD. Un modèle a été développé pour expliquer la collection de charge excessive observée dans les détecteurs planaires en silicium lors de leur exposition a une dose extrême de radiations. Finalement, un modèle simple de digitalisation à utiliser pour la simulation de performances détecteurs pixels individuels exposés à des faisceau de haute énergie ou bien de l’ensemble du détecteur interne est présenté. Ce modèle simple permets la comparaison entre les données obtenue en faisceau test aux modèle de transport de charge inclut dans ladigitalisation. Le dommage dû à la radiation , l’amincissement et l’utilisation de structures à bords minces sont autant de structures dont les effets sur la collecte de charges affectent les performance du détecteur. Le modèle de digititalisation fut validé pour un détecteur non-irradié en comparant les résultats obtenues avec les données acquises en test faisceau de haut énergie. Le modèle validé sera utilisé pour produire la première simulation de l’IBL incluant les effets d’amincissement du substrat, de dommages dûes aux radiations et de structure dotés de bords fins. / In this work, is presented a study, using TCAD simulation, of the possible methods of designing of a planar pixel sensors by reducing their inactive area and improving their radiation hardness for use in the Insertable B-Layer (IBL) project and for SLHC upgrade phase for the ATLAS experiment. Different physical models available have been studied to develop a coherent model of radiation damage in silicon that can be used to predict silicon pixel sensor behavior after exposure to radiation. The Multi-Guard Ring Structure,a protection structure used in pixel sensor design was studied to obtain guidelines for the reduction of inactive edges detrimental to detector operation while keeping a good sensor behavior through its lifetime in the ATLAS detector. A campaign of measurement of the sensor’s process parameters and electrical behavior to validate and calibrate the TCAD simulation models and results are also presented. A model for diode charge collection in highly irradiated environment was developed to explain the high charge collection observed in highly irradiated devices. A simple planar pixel sensor digitization model to be used in test beam and full detector system is detailed. It allows for easy comparison between experimental data and prediction by the various radiation damage models available. The digitizer has been validated using test beam data for unirradiated sensors and can be used to produce the first full scale simulation of the ATLAS detector with the IBL that include sensor effects such as slim edge and thinning of the sensor.

The elements of Social Welfare Social Welfare, Social Welfare Work and Health are assured by public and society actions. The State protectors measures win the public politics denomination, resulting in obligation to do of the State, to depend on expenses, for promote the materialization of social welfare rights. The present study will broach the statute guard, it means, that preview in Statute of the Adolescent and the Child Statute, which forces the guardian to gives moral, educational and material assistance to the child. The problem which caused this search begin with the 9528/97 law, which excluded the child on guard of the 8.213/91 law in the list of economic dependents. That law regulates the social welfare benefits. Those benefits are counted fundamental rights to dependents by the supreme law of State, therefore, refusal to child on guard, results in indagation about the legislative exclusion mention above. The present work have the analyses of Social Welfare and those requisites like investigate axle, as same as studies of protective s and constitutionals doctrines of inclusion, establishing the presupposes of social welfare benefits concessions and public politics, connecting all the themes with child on guard. The focus will involve also the investigation of Social Welfare doctrines and The Constitutional Theory of Fundamental Social Rights, apply to infancy and youthfulness. Then, we will examine the family protect notion and the families modalities admitted in the Brazilian law ordainment. / A Seguridade Social apresenta como finalidade suprema a promoção do bem-estar e o alcance da justiça social. Os elementos da Seguridade Previdência, Assistência e Saúde - são assegurados pelas ações de iniciativa dos Poderes Públicos e da Sociedade. As medidas protetoras estatais ganham a denominação de políticas públicas, implicando uma obrigação de fazer do Estado, a depender de gastos financeiros, para promover a realização dos direitos securitários. Abordaremos neste estudo a guarda estatutária, ou seja, aquela prevista no Estatuto da Criança e do Adolescente que obriga o guardião à prestação de assistência material, moral e educacional ao menor. O problema que motivou esta pesquisa teve origem na Lei 9528/97, que excluiu o menor sob guarda do rol de dependentes econômicos da Lei 8.213/91, esta última que regulamenta os benefícios previdenciários. Tais benefícios são constitucionalmente considerados como direitos fundamentais aos dependentes, logo, uma vez não concedidos aos menores sob guarda provocam indagações sobre a exclusão legislativa mencionada. O presente trabalho tem como eixo investigativo a análise da Previdência Social e seus requisitos, bem como o estudo das doutrinas protetivas constitucionais de inclusão, estabelecendo os pressupostos de concessão dos benefícios previdenciários e das políticas públicas, relacionando todas as temáticas com o menor sob guarda. O foco envolverá também a investigação das Doutrinas de Seguridade Social e da Teoria Constitucional dos Direitos Sociais fundamentais, aplicados à infância e à juventude. Outrossim, examinaremos a noção de família protegida e as modalidades familiares admitidas no ordenamento jurídico brasileiro.
