Since the beginning of the early 20th century bed rugs have been interesting research objects, but only in passing researchers have paid attention to rugs woven with rags. Noone has taken a closer look upon the reasons why people have woven these rugs. What does the materials of the rag – like recycled garments and interior textiles in the form of clothing rags – have to tell about the times when these rugs were woven? Did the rag rugs have any specific function or were the materials available and therefore used? The main sources of information are 21 rag rugs from Roslagen in Uppland, with a varied amount of rags. They were woven during the latter half of 19th century, and estate inventories from Väddö- and Häverö Ship District have altogether given some answers to the primary question of this paper: in wich way can the examined bed rugs bear witness to the use and value of recycled textile materials and the view of these in the context of the community where they were manufactured and used? This research doesn´t give an answer to whether these rugs have any particular function or not. Instead these rag rugs can be looked upon as representing a general development of the society towards an increasing amount of textiles surplus material. This being due an increasing consumption of factory-made clothing and textiles, manufactured in factories, as well as the paper mills development from producing paper made of cellulose rather than textile waste. To this we can add a principle lingering on from the 19th century, of domestic production and a thrift of resources. This resulted in an obvious recycling of discarded textiles. The home weaving of interior textiles was still strong by the end of the 19th century, and in Rosagen there was also a long tradition of weaving and of using rugs in the beds. At the same time there was, in the coastal regions of Roslagen, a local need for warming covers in boats and boat houses. This demand was related to the shooting of seals and other hunting in the coastal areas, as well as in the fishing- and maritime trades.

This thesis investigates how an autonomous reinforcement learning agent can improve on an approximate solution by augmenting it with a small patch, which overrides the approximate solution at certain states of the problem. In reinforcement learning, many approximate solutions are smaller and easier to produce than ???flat??? solutions that maintain distinct parameters for each fully enumerated state, but the best solution within the constraints of the approximation may fall well short of global optimality. This thesis proposes that the remaining gap to global optimality can be efficiently minimised by learning a small patch over the approximate solution. In order to improve the agent???s behaviour, algorithms are presented for learning the overriding patch. The patch is grown around particular regions of the problem where the approximate solution is found to be deficient. Two heuristic strategies are proposed for concentrating resources to those areas where inaccuracies in the approximate solution are most costly, drawing a compromise between solution quality and storage requirements. Patching also handles problems with continuous state variables, by two alternative methods: Kuhn triangulation over a fixed discretisation and nearest neighbour interpolation with a variable discretisation. As well as improving the agent???s behaviour, patching is also applied to the agent???s model of the environment. Inaccuracies in the agent???s model of the world are detected by statistical testing, using a selective sampling strategy to limit storage requirements for collecting data. The patching algorithms are demonstrated in several problem domains, illustrating the effectiveness of patching under a wide range of conditions. A scenario drawn from a real-time strategy game demonstrates the ability of patching to handle large complex tasks. These contributions combine to form a general framework for patching over approximate solutions in reinforcement learning. Complex problems cannot be solved by brute force alone, and some form of approximation is necessary to handle large problems. However, this does not mean that the limitations of approximate solutions must be accepted without question. Patching demonstrates one way in which an agent can leverage approximation techniques without losing the ability to handle fine yet important details.

Shadow removal is an important problem for both artists and algorithms. Previous methods handle some shadows well but, because they rely on the shadowed data, perform poorly in cases with severe degradation. Image-completion algorithms can completely replace severely degraded shadowed regions, and perform well with smaller-scale textures, but often fail to reproduce larger-scale macrostructure that may still be visible in the shadowed region. This paper provides a general framework that leverages degraded (e.g., shadowed) data to guide the image completion process by extending the objective function commonly used in current state-of-the-art image completion energy-minimization methods. This approach achieves realistic shadow removal even in cases of severe degradation and could be extended to other types of localized degradation.

Le recollement sur les corps, introduit par Harbater et Hartmann, et étendu par ces auteurs et Krashen, a récemment trouvé de nombreuses applications. Nous présentons ici une extension de cette technique au cadre de la géométrie analytique de Berkovich et des applications au principe local-global.Nous montrons que cette adaptation du recollement peut s'appliquer aux courbes analytiques de Berkovich, et par conséquent obtenons des principes locaux-globaux sur les corps de fonctions de courbes définies sur des corps ultramétriques complets. Grâce à la connexion entre les points d'une courbe analytique de Berkovich et les valuations dont on peut munir son corps de fonctions, nous obtenons un principe local-global par rapport à des complétés du corps de fonctions considéré, ce qui présente une ressemblance avec des versions plus classiques. En application, nous établissons des principes locaux-globaux dans le cas plus précis des formes quadratiques et en déduisons des bornes sur l'u-invariant de certains corps. Nos résultats généralisent ceux de Harbater, Hartmann et Krashen.Comme point de départ pour le recollement en dimension supérieure dans un cadre d'espaces de Berkovich, nous montrons que cette technique peut s'appliquer autour de certaines fibres d'une courbe analytique relative. Nous l'utilisons ensuite pour démontrer un principe local-global sur les germes des fonctions méromorphes sur ces fibres. En montrant que ces germes de fonctions méromorphes sont algébriques, nous obtenons aussi des principes locaux-globaux sur les corps de fonctions des courbes algébriques définies sur une famille plus vaste de corps ultramétriquesField patching, introduced by Harbater and Hartmann, and extended by the aforementioned authors and Krashen, has recently seen numerous applications. We present an extension of this technique to the setting of Berkovich analytic geometry and applications to the local-global principle.In particular, we show that this adaptation of patching can be applied to Berkovich analytic curves, and as a consequence obtain local-global principles over function fields of curves defined over complete ultrametric fields. Because of the connection between the points of a Berkovich analytic curve and the valuations that its function field can be endowed with, one of these local-global principles is given with respect to completions, thus evoking some similarity with more classical versions. As an application, we obtain local-global principles for quadratic forms and results on the u-invariant. These findings generalize those of Harbater, Hartmann and Krashen.As a starting point for higher-dimensional patching in the Berkovich setting, we show that this technique is applicable around certain fibers of a relative Berkovich analytic curve. As a consequence, we prove a local-global principle over the germs of meromorphic functions on said fibers. By showing that said germs of meromorphic functions are algebraic, we also obtain local-global principles over function fields of algebraic curves defined over a larger class of ultrametric fields

Many citizens living in Old Havana, Cuba, do not have regular access to potable water in their homes. As a result, this thesis explores how the water infrastructure in Old Havana shapes the everyday lives of local residents. The empirical material in this study was collected during two months of minor field studies in Havana mainly through the qualitative research methods of interviews and diaries but also through observations. The results were analyzed through four main theoretical concepts: the social practice approach in technology, hydraulic citizenship, social practice theory and feminist theory. Results revealed that the local water infrastructure produces and reproduces social inequalities and domestic do-it-yourself practices. It was also revealed that women carry out most of the domestic water activities, largely due to prevailing machismo ideals and traditional gender norms. Consequently, women in Old Havana are generally more affected by water supply irregularities and malfunctioning infrastructure than men.

Der volle Inhalt der QuelleAnnotation:
Les logiciels de patching audio traditionnels, tels que Max ou Pure Data, sont des environnements qui permettent de concevoir et d’exécuter des traitements sonores en temps réel. Ces logiciels sont mono-utilisateurs, or, dans bien des cas, les utilisateurs ont besoin de travailler en étroite collaboration à l’élaboration ou à l’exécution d’un même traitement. C’est notamment le cas dans un contexte pédagogique ainsi que pour la création musicale collective. Des solutions existent, mais ne conviennent pas forcément à tous les usages. Aussi avons-nous cherché à nous confronter de manière concrète à cette problématique en développant une nouvelle solution de patching audio collaborative, baptisée Kiwi, qui permet l’élaboration d’un même traitement sonore à plusieurs mains de manière distribuée. À travers une étude critique des solutions logicielles existantes nous donnons des clefs de compréhension pour appréhender la conception d’un système multi-utilisateur de ce type. Nous énonçons les principaux verrous que nous avons eu à lever pour rendre cette pratique viable et présentons la solution logicielle. Nous exposons les possibilités offertes par l’application et les choix de mise en œuvre techniques et ergonomiques que nous avons faits pour permettre à plusieurs personnes de coordonner leurs activités au sein d’un espace de travail mis en commun. Nous revenons ensuite sur différents cas d’utilisation de ce collecticiel dans un contexte pédagogique et de création musicale afin d’évaluer la solution proposée. Nous exposons enfin les développements plus récents et ouvrons sur les perspectives futures que cette application nous permet d’envisagerTraditional audio patching software, such as Max or Pure Data, are environments that allow you to design and execute sound processing in real time. These programs are single-user, but, in many cases, users need to work together and in a tight way to create and play the same sound processing. This is particularly the case in a pedagogical context and for collective musical creation. Solutions exist, but are not necessarily suitable for all uses. We have tried to confront this problem in a concrete way by developing a new collaborative audio patching solution, named Kiwi, which allows the design of a sound processing with several hands in a distributed manner. Through a critical study of the existing software solutions we give keys of comprehension to apprehend the design of a multi-user system of this type. We present the main barriers that we had to lift to make this practice viable and present the software solution. We show the possibilities offered by the application and the technical and ergonomic implementation choices that we have made to allow several people to coordinate their activities within a shared workspace. Then, we study several uses of this groupware in pedagogical and musical creation contexts in order to evaluate the proposed solution. Finally, we present the recent developments and open up new perspectives for the application

The rapid emergence of embedded devices and sensor networks that frequently exchange object-level images foretells an increasing reliance on object-level systems. Additionally, nearly all computing systems, including control systems, enterprise applications, scientific codes and dynamic libraries operate eventually at the object code level. Studying adaptivity and runtime composition issues in such systems is becoming an important focus of systems research. In this thesis, we describe an object-level framework that will manipulate an object module to instrument control functionality and adaptivity in order to realize complex compositional scenarios. Using function and parameter remapping capabilities, our framework transcends programming language and design boundaries, and enables applications to adapt dynamically during runtime. We introduce the capability to "restart" an application automatically, a feature we utilize to support adaptivity not only spatially, over the algorithm domain, but temporally as well. A high-level adaptive control language based on XML is presented that allows complex adaptive scenarios to be expressed concisely. Additionally, the construction of several adaptive scenarios using our framework is illustrated, along with several experiments in ``learning adaptivity`` using reinforcement learning techniques.Master of Science

Approved for public release; distribution is unlimitedThis paper presents the design of a carbon nanotube-based sensor to detect crack propagation in aluminum structures underneath composite patching. Initial tests are utilized to determine the correct procedure and materials to properly fabricate a carbon nanotube (CNT) sensor, which is then placed in between a composite patch and the aluminum structure. CNTs have been utilized as sensors in previous studies but only for sensing crack propagation within the composite itself. This study focuses on crack propagation in the base material and is not concerned with the composite. In this application, the composite is only a patch and can be replaced if damaged. This study utilizes both tension and fatigue testing to determine the usefulness of the CNT sensor. The CNT sensor is shown to be effective in giving an indication of the crack propagation in the aluminum. Correlation is done between the propagation length and the increase in resistance in the CNT sensor for tensile testing as the crack width is large enough to obtain an appreciable resistance change.

Background. With the rise of Internet of Things and Internet connected devices many things become convenient and efficient but these products also carry risks. Even though a lot of people own devices like this not so many think of the consequences if these devices aren't secure. Objectives. Given this our thesis aims to discover the implications of vulnerable devices and also at what rate there are insecure, unpatched devices compared to the patched, secure counterpart. Methods. The approach implemented uses Shodan to find these devices on the internet and also to find version information about each device. After the devices are found the objective is to calculate a CVSS score on the vulnerabilities and the exploit that can abuse the vulnerability, if there exists any. Results. What we found was that 71.85% of a smart home server brand was running an insecure version. As to the consequences of having an insecure device, it can be severe.Conclusions. We found that, for instance, an attacker can without much difficulty shut off alarms in your smart home and then proceed to break into your house.

Researchers are learning how to prevent the projected United States shortage of science, technology, engineering, and mathematics (STEM) professionals by retaining more undergraduates in STEM majors. Specifically, since undergraduates generally want to give back to their communities, they experience heightened science career motivation once they "fit" their communal goals with their views of science careers. However, testing the quality of fit is challenging because individuals differ in communal goals and views of science. For the present study, therefore, a person-centered analytical approach was used to identify groups of STEM undergraduates defined by combinations of communal goal endorsement and perceived communal goal affordances. Four groups were identified: Low Incongruent, Moderately Low Incongruent, Average Congruent, and Moderately High Incongruent. Results showed that undergraduates were optimally motivated when both communal goal endorsement and perceived communal goal affordances were moderately high and incongruent. Results also showed that gender and cultural identity could predict group membership.

Följsamheten av ocklusionsbehandling hos barn med amblyopi är bristfällig. Det finns begränsat med forskning om vilka erfarenheter vårdpersonal har av denna bristande följsamhet, och det vore därför av intresse att undersöka vilka åtgärder ögonsjuksköterskor upplever kan vidtas för att främja följsamheten. Syftet med pilotstudien var därför att undersöka hur ögonsjuksköterskan kan främja följsamhetenav ocklusionsbehandling. Studien genomfördes som en beskrivande, kvalitativ pilotstudie med induktiv ansats där data analyserades med manifest kvalitativ dataanalys. I resultatet framkom fem kategorier, vilka påvisade vikten av att ögonsjuksköterskor tänker på att bemöta vårdnadshavare och barn med ett icke-dömande förhållningssätt, att ge tydlig och individanpassad information både muntligt och skriftligt, samt olika praktiska råd kring själva genomförandet av behandlingen. I resultatet framkom även vikten av att skapa en personlig relation vårdpersonal, vårdnadshavare och barn emellan och betydelsen av täta återbesök, samt hur ett gott samarbete och stöd kollegor emellan kan främja följsamheten. Rekommendationer för vårdverksamhet är bland annat att ge vårdnadshavare och barn kontinuitet vid besöken och rekommendationer för utbildning inom omvårdnad att lära ut vikten av ett positivt förhållningssätt och att ställa öppna frågor. Större studier med samma syfte är av intresse, samt forskning kring hur information på internet påverkar följsamheten.Adherence to occlusion therapy with amblyopic children is inadequate. There is limited with research about medical staff’s experiences of inadequate occlusion therapy. Therefore it is of importance investigating which arrangements ophthalmic nurses’ perceive can be taken to improve adherence. The purpose of this pilot study was to investigate how ophthalmic nurses can improve adherence to occlusion therapy. The study was conducted as a descriptive, qualitative pilot study with an inductive approach where data was analyzed with manifest qualitative content analysis. Five different categories were revealed and showed the importance of a non-judgmental attitude among ophthalmic nurses towards the child and the caregivers, the importance of giving both verbal and written comprehensible, individualized information. Practical advice about carrying out the occlusion therapy emerged in the data along with the importance of creating a personal relationship between the medical staff and the child/caregiver. Frequent revisits were seen as important, and good support and cooperation between colleagues was believed to be able to improve adherence. Recommendations for care activities is to give the child and the caregivers continuity during visits and a recommendation for nursingeducation is to teach the importance of a positive attitude and open-ended questions. Larger studies with the same purpose are of interest, also further research of how information on the internet affects adherence to occlusion therapy.

Der volle Inhalt der QuelleAnnotation:
Bone grafting is an integral part of reconstructive surgery. In the United States alone over 250,000 bone grafts were harvested annually. While autogenic bone grafting has always been associated with donor site morbidity, bone graft substitutes have been suggested as a solution. In this project, a bone graft substitute using human dental pulp cells (HDPCs) and peptide nanofibre hydrogel was being developed.
HDPCs were isolated from extracted teeth. After culture and expansion, unsorted HDPCs were encapsulated into peptide nanofibre hydrogel. These cell-gel constructs were cultured for two weeks in ordinary culture medium and then for 2-3 more weeks in osteogenic lineage induction medium. The post-induced cell-gel derived constructs were transplanted into skin pouches or calvarial bone defects of nude mice.
When transplanted subcutaneously, the cell-gel derived constructs were harvested at four to twelve weeks postoperatively (n=5). Tissue samples were processed for contact radiograph, histological examination and antibody staining. These constructs developed into vascularised, mineralised tissue pieces. Though bone marker proteins (osteopontin, osteocalcin and osteonectin) were detected in these tissue pieces, the histological structure of their tissue matrix did not resemble bone matrix.
Later, it was accidentally noted that portions of constructs touching the bone defect margin, would form bone through direct matrix transformation. This indicated that the current cell-gel model was potentially the first study model of tissue engineering bone by simulating intramembranous ossification.
In the bone defect trial, obviously mineralized cell-gel derived constructs of matching shape and size were selected to patch the 3mm calvarial bone defects (n=5). Bone defect specimens were harvested at two weeks post-operation. The development of radio-opaque structures within the bone defects were evaluated in virtual 3-dimensional models constructed with data collected by microtomographic scanning. The bone nature of these radio-opaque structure were validated histologically (by staining with Hematoxylin and Eosin, Periodic acid-Schiff stain and Picrosirius red) and immunologically (with antibody against human collagen-I, osteonectin and parathyroid hormone receptor). The radio-opaque structures developed into the bone defect were evaluated positive for bone. And significantly more bone regeneration was observed in the test group (n=4) than in the control (n=2). The mean area percentages of regeneration were 46.3% and 0% respectively (p< 0.05).
While the majority of studies in bone tissue engineering have worked with bone marrow stromal cells and scaffolds of synthetic polymer or calcium based materials, this is the first successful attempt of using HDPCs and peptide nanofibre hydrogel to engineer bone (in a nude mice mode). And the potential of these cell-gel derived constructs to promote bone regeneration was demonstrated.
But this was the result from a single experiment of small sample size in one animal model only. It needs to be fortified by further experiments with larger population size and in other animal models.
To increase clinical usefulness, the construct will need to be scaled up to centimetre size level. This will necessitate a change of its configuration from bead into meshwork. And, the data collected to date will shed light onto the redevelopment of all the relevant protocols.published_or_final_version

Over the last 20 years, electricity markets around the world have gradually been deregulated, creating wholesale markets in which generating companies compete for the right to supply electricity, through an offering system. This thesis considers the optimisation of the offering process from the perspective of an individual generator, subject to intertemporal constraints including fuel limitations, correlated rest-of-market behaviour patterns and unit operational decisions. Contributions from the thesis include a Pre-Processing scheme that results in considerable computational benefits for a two-level Dynamic Programming method, in addition to the development of a new process that combines the techniques of Decision Analysis and Dynamic Programming.

Enterprises require an information security solution that provides privacy, integrity, authentication and access controls for processes. License management systems are developed to be a solution for process authorization in different platforms. However, security threats on processes cannot be controlled with existing license management mechanisms. The need is a complete system that is independent from implementation, platform, and application. In this thesis, we design a complete system for process authorization based on Public Key Infrastructure (PKI) technology.

O objetivo deste trabalho é apresentar os conceitos da logística, em especial a logística de serviços, e algumas de suas ferramentas, como a roteirização de veículos e previsão de demanda por serviços, aplicadas aos serviços urbanos, neste caso o serviço de remendos em pavimentos, visando aumentar a eficiência desse serviço. O serviço de remendos, muitas vezes chamado de tapa-buracos, é uma atividade de manutenção comum nas cidades. Para observar a aplicação das ferramentas foi elaborado um estudo de caso na cidade de São Carlos. Dados sobre o serviço de remendos em pavimentos foram coletados e, com a ajuda de um sistema de informações geográficas SIG, foram gerados roteiros que foram comparados com os dados originais. As rotas simuladas pelo SIG foram mais eficientes do que as praticadas na realidade, mostrando a utilidade dos conceitos da logística e também a utilidade do SIG na gerência da infra-estrutura urbana. A previsão de demanda por serviços de remendos não pôde ser observada devido à falta de dados históricos, fundamentais a essa etapa do trabalho.The objective of this work is to introduce the concepts of logistics, especially the service logistics and some of its tools as the vehicle routing and the demand forecast for services, applied to the urban services, in this case the patching service in pavements in order to increase the efficiency of this service.

To observe the application of the tools one case study was elaborated in the city of São Carlos. Data about the patching service in pavements were collected and, helped by the geographic information system GIS, routes were created and compared to the original data. The paths simulated by the GIS were more efficient than the real ones, showing the utility of the logistics concepts and also the utility of the GIS on the management of the urban infrastructure. The demand forecast for services of patching could not be observed due of the lack of historical data, essential to this part of the work.

Im Automobilbau kommt zunehmend das sog. Multimaterial-Design zum Einsatz, um kostenattraktiven Leichtbau in Großserienanwendungen umzusetzen und das Leichtbaupotential von strukturellen Bauteilen in bislang meist monolithischer Bauweise zu erweitern. Die Patch-technologie, bei der die Strukturertüchtigung durch die lokale und anforderungsgerechte Einbringung von endlosfaserverstärkten Faser-Kunststoff-Verbunden (FKV) in dünnwandige metallische Bauteile erfolgt, ist eine zielführende Technologie, um einen hohen Leichtbaugrad zu generieren. Eine besondere Herausforderung stellt dabei die dauerhafte, flächige Verbindung von Metall und thermoplastbasiertem FKV (TP-FKV) dar. Da die verwendeten Werkstoffe keine hinreichende chemische Kompatibilität aufweisen, wurden bislang Klebstoffe als Fügehilfsstoff genutzt, wodurch jedoch zusätzliche Prozessschritte notwendig wurden und damit verbunden häufig höhere Prozesszeiten auftraten.
In dieser Arbeit werden Möglichkeiten zur Kompatibilisierung der beiden, das hybride Bauteil kennzeichnenden, Werkstoffkomponenten erarbeitet. Der Schwerpunkt wird dazu auf die Entwicklung und Charakterisierung einer inlinefähigen Vorbehandlungsmethode des metallischen Fügepartners in Kombination mit einer Modifikation des thermoplastischen FKV-Halbzeugs bzw. dessen Matrixsystems gelegt. Dabei werden die Einflüsse unterschiedlicher Vorbehandlungen und zugeordneter Vorbehandlungsparameter auf die physikalische und chemische Oberflächenbeschaffenheit des Metalls und das Haftniveau im TP-FKV/Metallverbund untersucht. Darüber hinaus werden mit Hilfe von Füllstoffen und Additiven verschiedene chemische Veränderungen des thermoplastischen Matrixsystems vorgenommen und deren Auswirkung auf die Adhäsion zwischen den Verbundpartnern charakteri-siert. Für die Anwendung des Verbundsystems TP-FKV/Metall in einem Automobil werden neben hohen mechanischen Eigenschaften (Verbundfestigkeit) insbesondere sehr gute Temperatur-, Klimawechsel- und Korrosionsbeständigkeiten gefordert, die in praxisnahen Untersuchungen nachgewiesen werden. Die gewonnenen Erkenntnisse zur prozessintegrativen Anpassung der Komponenten des Werkstoffverbundes werden anschließend in die Praxis übertragen. Dafür wird ein seriennaher Fertigungsprozess entwickelt und prototypisch umgesetzt. Der Einfluss der grundlegenden Prozessparameter Druck, Temperatur und Zeit auf die Güte der Verbindung wird evaluiert. Einfache bauteilnahe Demonstratoren werden genutzt, um die Tauglichkeit der Verbundstrategie und des entwickelten Fertigungskonzeptes der TP-FKV-Patchtechnologie für deren wirtschaftliche Anwendung in der Großserienfertigung im Umfeld der Automobilindustrie nachzuweisen.

In many areas of computer applications, such as MultiMedia Systems and Image Information Systems , image data is always huge and complicated. However, it includes some information which is not important. In fact, we are only interested in the information of importance. In this paper, we use the genetic algorithm to find a set of patches to represent and index the important part of an image. By using the set of patches to represent the image, the storage required can be reduced and the efficiency of processing can be increased.

This thesis presents a new texture synthesis algorithm. Unlike previous texture synthesis algorithm, blocks of input texture are first classified. The structure of the classified blocks of the input texture is formed and patched to the output texture as a basic unit. Our method synthesizes a new image by stitching together the basic structures of each class. Notwithstanding its simplicity, this method is a special-suited for existing textures, and it synthesizes typical textures within a few seconds on a middle-level PC.

Since Taiwan has joined the World Trade Organization, local firms must have its own competitive advantages in order to stay competitive in the world market. In fact having a complete information network will be an essential factor in keeping companies competitive. It is beneficial because it reduces operating costs and at the same time increase productivity. The down side of having an information network is encountering external threats such as hackers attacking the operating system or the application program. Evidently, internet access provides people with lots of convenience. The con of internet is its vulnerability of viruses spreading and Hacker attacks. These issues are now having great impacts on most businesses. Thus Internet securities have became an important aspect that every company should concern because it is virtually impossible to claim that virus or hacker attacks will never happen to us. Along with the convenience of internet, security vulnerability of the cyber environment has become a major issue facing most organizations. Therefore, providing a consistent and secure information and internet network is the primary task for most organizations. One of the methods the organization can ensure a consistent and secure information and internet network by building an auto-patching mechanism for security vulnerability and have of operation system and program that I built. The auto-patching mechanism can ensure the regularity and security of the information system and the internet.

The popularity of Internet multimedia applications has grown dramatically in the past several years. The multimedia streaming demands high transmission bandwidth requirement. There are several methodologies about reducing the server workload and the network traffic has been published. Patching is one of these methodologies; it allows a client to receive a multicast stream by listening to an ongoing transmission of the same video clip to reduce frames transmitted from the server. Greedy Buffer Reuse (GBR) is a patching algorithm that minimizes the server and the network transmission bandwidth requirements. However, multimedia streams multicasting to clients must be stored in a client buffer with the limited size. The fractions of multimedia streaming will be lost due to the limited size of the client buffer. Those frames are called patching frames because the client needs to patch those frames from the server. We propose a patching scheduling algorithm to schedule each patching frame on the ongoing streaming cached in the proxy. This will further reduce frames that need to be patched from the server. Prefix frames patched from the server will be increased when requests arrive close. This may make the reduction ratio of patching scheduling down. In order to solve this particular circumstance, we present a patching scheduling with prefix caching mechanism. This mechanism is to share the space of the proxy cache for both patching scheduling and prefix caching. The simulation results show that the proxy can reduce large server overhead and network traffic under patching scheduling with prefix caching mechanism when a video clip is popular in the multimedia server.

This thesis presents a novel approach for increasing packaging rate.A paper-patching tracking system is established that controls two package-paper running at the same speed so that the paper-patching processes can be done on-line without stopping packaging machine.This leads to develop a paper- patching tracking servo mechanisim system.A servo motor driving a table above a paper flow line is build up where a nontouchable sensor is placed on the table to measure the relative displacement between the table and the mark of the working package-paper.The aim of the feedback control design is to keep the velocity and position of the table the same as the mark.In the feedback control design,we apply Ｈ∞ control theory to meet desirable performance in the presence of uncertainties.The nonlinearity of the optical sensor is also studied,and a feedforward control methods is developed by computer software to overcome the saturation behavior.A DSP- based real-time control scheme is established to implement the feedback and feedforward controller. There is a great of potential of this work to the packaging machines application for reducing the operation time in changing package-papers.

Eye patching is a commonly used strategy for remediating vision and visual attention deficits. This thesis was designed to investigate the behavioral and neurological effects on the performance of bilateral symmetrical attention. Eighteen right handed college male students participated this study to perform the line bisection and the computerized landmark tasks under three conditions: (1) non-patching condition; (2) right monocular patching condition; and (3) right hemi-field patching condition. Besides the behavioral data collected in both tasks, the event -related potentials (ERPs) were also investigated in the landmark task. Findings of the line bisection performance showed a more manifest leftward error under the right hemi-field patching condition than others (F(2.30, 17.28) = 5.27, effect size eta = .64, p = .01). Nevertheless, the right monocular patching presented greater rightward error than other conditions. The results of early event-related potentials (50-90 msec post stimulus) showed the peak amplitude differences between right/left occipital regions among three patching conditions were significant (F(2.84, 21.27) = 3.42, effect size eta = .56, p = .04). Especially, the right occipital regions were activated more under the right hemi-field patching condition. Similarly, in the late phase (140-300 msec post stimulus), the right lateralized effect was also found in the parietal regions under the condition of right hemi-field patching. As a result, the right hemi-field patching might increase the right hemisphere activation and the awarness of left visual hemispace. Whereas, the right monocular patching condition was not able to achieve this right lateralized effect, it might induce the attentional bias to right hemispace. These behavioral and electrophysiological findings will be used to substantiate the meaning of eye patching on neurobehavioral theory and visual rehabilitation.

The linear chromosomes and plasmids are common in Streptomyces. The telomeres of these linear replicons share the same characters, like palindrome rich sequences and 5’capped terminal proteins (TP). The replications of these linear replicons are initiated from an internal origin then bi-directionally toward to the ends. Finally, the lagging strands will leave a single-stranded gap at the 3’ end, which was supposedly patching up by TP-primed replication. A working model suggests that the protruding 3’ end folds back and forms stably secondary structure, by abundantly and persistently palindromic sequences in the terminal regions, as the intermediate for terminal patching. The known telomeres of Streptomyces are separate into two groups by their DNA sequences and palindromic structures. The typical group, coming from most Streptomyces chromosomes and plasmids, is composed by tightly palindromic sequences and the very end sequences are within a conserved palindrome. The atypical group, which those are composed by loosely palindromic sequences and their very end sequences are not within a palindrome, their sequences can’t alignment well with each other or any one of typical group. To study the function of the telomere sequences in the atypical group during replication, we focused on the best studied SCP1 which has showed 4 to 6 continued “G” on its very end sequence with the following sequence composed by loosely palindromic structures by forcing cloning. By different site direct mutagenesis methods, we generated a series of mutant telomeres and examined their function on linear plasmids in vivo. If the mutated telomeres can support the replication of the linear plasmids in Streptomyces, the mutated nucleotide(s) is not essential for end patching. Using this strategy, we found that (1) only the first 84 bp of the telomere was essential; (2) the palindrome I and II regions were required for linear DNA replication, but not palindrome IV; (3) five continued nucleotides (G) was sufficient; and (4) the sequence and length of palindrome I was not important. These results define the essential telomere sequence for end patching of SCP1.

Programs are inherently with bugs for we can only prove their presence but not their absence. In order to maintain the quality of software and get rid of bugs, developers need to fix them and release corresponding patches. When patching the software on Microsoft Windows, we usually terminate the software first, apply related patches, and restart the system. Such a process is expensive to shutdown the system only for patching and fixing the software bugs. Much research efforts focus on dynamic software updating (DSU) with static analysis on source code. Our work, called DUBS, instead tries to develop DSU on Commercial Off-The-Shelf (COTS) software. To prove the applicability of our binary updating mechanism, we apply DSU on Buffer overflow detection. Such techniques have been well developed but they can not be applied to server dynamically, due to their high execution overhead. We develop a tool by our binary DSU which could detect buffer overflow vulnerability dynamically. Users can optionally enable the detection mechanism and use this tool to patch the vulnerability dynamically in COTS on Microsoft Windows without stopping the program. We perform the experiment on COTS and can successfully block the attack from malicious users.

When defects or cracks exist in a structure, patching is one of the best solutions to enhance the structural safety and to save the repair expenses. Because composite materials have the characteristics of light weight and high strength-to- weight and stiffness ratios, they have found their ways into most subsys- tems of aeronautic and aerospace vehicles in the recent years. Various parameters must be considered in composite patching te- chnique such as patching designs, material selections, repair methods, environmental factors, defect testings, economic consi- derations, etc. A series of aluminum alloy sheets containing a central crack were manufactured in this dissertation. Effects of various stacking sequences, fiber orientations and repair methods of composite patchings on the stress intensity factor (SIF) were investigated. Then the repair efficiency can be calculated in terms of the SIF. In the past, the combined experimental and numerical method, so-called hybrid method, was seldom utilized to investigate the composite patching problems. In this dissertation, in addition to the adopted experimental method, i.e. the electronic speckle pattern interferometry (ESPI) method, the numerical method, i.e. the finite element method (FEM) and the hybrid method were used to investigate the repair efficiency of composite patching. In addition, maximum shear stress in the adhesive, maximum peeling stress in the adhesive and maximum principal stress in the pat- ching were also investigated by the FEM and the hybrid method.

This study is to explore the effectiveness of bonding factors for adhesive material and treatment by patching one-side composite material and touching up the test sample of metal structure, tests of structure fatigue and life durability will be conducted between test group and control group to screen the effective parameters of factors. The bonding intensity of adhesive shows its significance effectiveness with adhesive category and surface treatment individually, environmental factor is also incorporated to adopt the proper adhesive and the way of surface treatment in order to meet the intensity requirement. Both tests for equal amplitude and standard amplitude of vibration on specified loading on patch or non-patch shows composite patch can share less force loading to 70 percent of initial structure loaded. The average effectiveness on intensity of equal amplitude test for patch bonding is eight times of non-patch bonding, and it is three times of non-patch bonding for standard amplitude test. This result indicates better touch up for aging aircraft structure which exists lateral crack on sin pore.

In the past, conservators used to patch the silk paintings with long-preserved silk or the blank spaces of old silk paintings. Nowadays, artificial degraded silk similar to old silk can be created through accelerated aging technology. Initiated by Japan, the accelerated aging process is to apply acid or alkali to the silk and illuminate it with electron rays, such asγray. However, there are differences in painting silk due to different manufacturing process and the times. The painting silk of single weaving method or single degradation level can not meet the needs of different cases. This time, we obtained support layer whose texture was very similar to the original painting. They are in accord with each other in grain, color, and roundness of the silk thread. Therefore, the support layer was adopted as the filling materials for this case. The degraded silk newly-developed by Taiwan is similar to Japanese products in texture. As a result, the newly-developed degraded silk was chosen for trail and compared with the naturally aging silk to see their differences in efficiency. Patching in the same way, the matching degree with the original paintings, the feel during the repair process and the texture after color unification were all recorded in detail by pictures and text. This project is expected to be the effective reference for future choice and development of degraded silk. From repair project of Teng-Jiao Su’s fan, we’ve learned that the more the conditions and texture of the patching materials similar to the original painting, the greater the effects after color unification. The degraded silk developed by Taiwan had great performance in color unification and fragility of the silk. Nevertheless, more various kinds of man-made silk were needed, which is an obvious difficulty we met.

The purpose of this research is to heal personal memories of loss through discussing the connection of self-emotions and linear material that extends to become the form of hand making created by one’s subconscious needs. The thread of thoughts and methods in creating echo to the basic theories of psychological analysis and dream theory. As for the practice of creating, this research focuses on the linear features of the materials being led by body awareness to further “darn” the holes on one’s emotion. The research discovered that the therapy method of one’s loss memories could refer to two surfaces: 1. Search for the subconscious needs in the forms of materials. 2. Ignore figures of objective items and not to describe the forms of items, which can enable to avoid psychological review of self and further helps one to freely express the form of mind. The finish of work shall become the achievement of therapy.

The development of communication technology has provided malicious users formidable means to launch attacks through Internet of Things (IoT). The features of IoT devices which include constrained resources, heterogeneous links, and vulnerable usability facilitate the malware propagation, thereby raising new challenges on handling IoT-empowered malware for cyber security. The malware propagation control scheme in traditional wireless networks where nodes can be directly repaired and secured is not suitable for IoT since IoT devices are hard to be patched. To efficiently and effectively suppress the spreading of harmful information, blocking malware via patching the intermediate nodes (e.g., base stations, access point) instead of the infected mobile devices becomes our better choice. On the other hand, we analyze this network by exploiting the well-known epidemic model and the concept of spectral clustering. The clustering algorithm can avoid that all the patching resources being given to the area with the highest average traffic volume and neglect the intermediate node in other areas which also need to be patched. This article proposes a novel clustered traffic-aware patching scheme to select important infrastructures to patch, which is suitable for the IoT system with limited patching resources and response time constraint. We conduct experiments on real-world trace datasets by using Opportunistic Network Environment (ONE) simulator to show the advantage of clustered traffic-aware patching scheme in mitigating malware propagation, and clustered traffic-aware patching has better performance than intuitive degree-based patching.
