Full textAbstract:
Most of fracture parameters (K, G, J-integral, COD) break down, especially for ductile materials and large crack extensions. In addition, even at small scale yielding, K, G, J- integral and COD are limitedly used to distinguish the onset of unstable fracture, without any concern regarding the pre-onset and post-reaction. On the other hands, the specimen size and geometry dependences of K/G/J-integral/COD are beyond the capability of the classical Fracture Mechanics where most of methodologies rely on only a single-parameter to characterize the structural integrity. In essence, K/G/J-integral/COD are based on the same underlying idea of energy released per crack extension. Thus, when crack extension is accompanied by the other irreversible energy dissipation, neither J-integral nor COD/CTOA is able to describe the failure processes (crack onset, growth and catastrophic fracture). Moreover, K/G/J-integral/COD are by definition global parameters in nature. Their average field characters are unable to describe some mechanical behaviour inherent to material heterogeneity and disorder. As a result, it is no wonder that the applications of K/G/J-integral/COD are severely limited, and even invalid as observed in substantial experiments.
The cohesive zone model and fractal approach are the cornerstone in this thesis. It is essential that a proper fracture theory should basically take into both the stress intensification and material disorder at different scales into account. A Hardening Cohesive/Overlapping Zone Model is proposed for the analysis of complex mechanical phenomena in fracture of metallic materials. It is assumed that the unique correspondence between uniaxial tension/compression and ductile fracture can be established. As a result, the advantages of the cohesive crack model are kept in order to simulate the stress and strain concentrations. Most metals and alloys are not homogeneous. Thus, macroscopic level behaviours are essentially originated from a microscopic one, as well as taking into account local fluctuations due to disorder. Especially, fracture is quite sensitive to disorder, and sometimes mean field theory without consideration of disorder is not able to provide accurate predications. The fractal approaches to scale effects are adopted to introduce the inherent effects from material disorder at different scales. The scale-independent cohesive and overlapping laws with respect to the classical stress–strain relations can be presented. Consequently, fractal approach can avoid the limitations of a classical mean-field approach, where disorder is simply averaged in an elementary representative volume. In addition, energy brittleness number sE is proven to be a characteristic parameter to evaluate the fracture instability not only in quasi-brittle materials but also in metallic materials under certain conditions.

Senthil, Rathna. "IDLE: A Novel Approach to Improving Overlapping Community Detection in Complex Networks." Thesis, Virginia Tech, 2016. http://hdl.handle.net/10919/65160.
Full textAbstract:
Complex systems in areas such as biology, physics, social science, and technology are extensively
modeled as networks due to the rich set of tools available for their study and analysis. In such
networks, groups of nodes that correspond to functional units or those that share some common
attributes result in densely connected structures called communities. Community formation is an
inherent process, and it is not easy to detect these structures because of the complex ways in which components of these systems interact.
Detecting communities in complex networks is important because it helps us to understand
their internal dynamics better, thereby leading to significant insights into the underlying systems.
Overlapping communities are formed when nodes in the network simultaneously belong to more
than one community, and it has been shown that most real networks naturally contain such an overlapping community structure. In this thesis, I introduce a new approach to overlapping community detection called IDLE that incorporates ideas from another interesting problem: the identification of influential spreaders. Influential spreaders are nodes that play an important role in the propagation of information or diseases in networks. Research suggests that the main core identified by k-core decomposition techniques are the most influential spreaders. In my approach, I use these k-cores as candidate seeds for local community detection. Following a well-defined seed selection process, IDLE builds and prunes their corresponding local communities. It then augments the resulting local communities and puts them together to obtain the global overlapping community
structure of the network.
My approach improves on the current local community detection techniques, because they use
either random nodes or maximal k-cliques as seeds, and they do not focus explicitly on detecting
overlapping nodes in the network. Hence their results can be significantly improved in building
ground-truth overlapping communities. The results of my experiments on real and synthetic networks indicate that IDLE results in enhanced overlapping community detection and thereby a
better identification of overlapping nodes that could be important or influential components in the
underlying system.Master of Science

Full textAbstract:
Human rights as codified in international documents are claims every human being have by virtue of being a human. Meaning that every state must ensure, through its laws, that each individual is guaranteed these claims or rights equally. Islamic principles like other religions are obligations that its members (Muslims) must perform rather than claims. Therefore, it is possible that individual rights may not be respected within Islamic principles because, of the differences in their origin and emphasis, one is a claim and the other a duty of believers.
The concern of violating rights of other people within Islamic law calls into attention how Islamic principles can be applied in a state while guaranteeing human rights as universal principles.
This study discusses various approaches proposed by Muslim authors on how human rights can be justified in Islam. Since human rights are political concepts, in the sense that each state must ensure that human beings go about their life freely, they should be the focus of consensus among different doctrines in a modern state. That is a principle to justify human rights in Islam must consider the fact of pluralism of religious doctrines and how all are included in the political process of the state.

Salmons, David. "The overlapping of legal concepts : a legal realist approach to the classification of private law." Thesis, University of Birmingham, 2011. http://etheses.bham.ac.uk//id/eprint/3227/.
Full textAbstract:
The main aim of this research is two-fold; firstly, these chapters will seek to demonstrate the unreliability of theoretical or abstract approaches to legal reasoning in describing the law. Secondly, rather than merely providing a deconstruction of previous attempts to classify private law, the chapters attempt to construct an overlapping approach to classification. This represents a new way of classifying private law, which builds on the foundations of the lessons of legal realism and explains how classification can accommodate overlaps to assist in identifying the core elements of private law reasoning. Following the realist tradition, the thesis argues for narrower formulations of the concepts of property, contract and tort. It is then argued that within these narrower concepts, the law is made more predictable and clearer. Importantly, adopting the overlapping analysis, we can explain the areas that we have removed from property, contract and tort as overlaps with these core concepts. The purpose is to recognise that legal concepts can be best understood as links between facts and judicial decision making, and the best way to achieve this is to reject discrete categorisation and, instead, to recognise the overlapping of legal concepts.

Nusrat, Nazia. "Development of novel electrical power distribution system state estimation and meter placement algorithms suitable for parallel processing." Thesis, Brunel University, 2015. http://bura.brunel.ac.uk/handle/2438/10902.
Full textAbstract:
The increasing penetration of distributed generation, responsive loads and emerging smart metering technologies will continue the transformation of distribution systems from passive to active network conditions. In such active networks, State Estimation (SE) tools will be essential in order to enable extensive monitoring and enhanced control technologies. In future distribution management systems, the novel electrical power distribution system SE requires development in a scalable manner in order to accommodate small to massive size networks, be operable with limited real time measurements and a restricted time frame. Furthermore, a significant phase of new sensor deployment is inevitable to enable distribution system SE, since present-day distribution networks lack the required level of measurement and instrumentation. In the above context, the research presented in this thesis investigates five SE optimization solution methods with various case studies related to expected scenarios of future distribution networks to determine their suitability. Hachtel's Augmented Matrix method is proposed and developed as potential SE optimizer for distribution systems due to its potential performance characteristics with regard to accuracy and convergence. Differential Evolution Algorithm (DEA) and Overlapping Zone Approach (OZA) are investigated to achieve scalability of SE tools; followed by which the network division based OZA is proposed and developed. An OZA requiring additional measurements is also proposed to provide a feasible solution for voltage estimation at a reduced computation cost. Realising the requirement of additional measurements deployment to enable distribution system SE, the development of a novel meter placement algorithm that provides economical and feasible solutions is demonstrated. The algorithm is strongly focused on reducing the voltage estimation errors and is capable of reducing the error below desired threshold with limited measurements. The scalable SE solution and meter placement algorithm are applied on a multi-processor system in order to examine effective reduction of computation time. Significant improvement in computation time is observed in both cases by dividing the problem into smaller segments. However, it is important to note that enhanced network division reduces computation time further at the cost of accuracy of estimation. Different networks including both idealised (16, 77, 356 and 711 node UKGDS) and real (40 and 43 node EG) distribution network data are used as appropriate to the requirement of the applications throughout this thesis.

Full textAbstract:
Thermoplastic prepregs that are also known as organo sheets are processed in presses and formed to half shells. Larger components can be produced by joining the half shells, which results in hollow bodies. However, current manufacturing technologies allow only cap profile shaped joints, which cause fiber deflections in the joint plane. This paper shows that overlapping infrared welds in organo sheets enable weld strengths close to the interlaminar shear strengths of the unwelded materials and thus a fiber utilization across the joint plane. By using high welding pressures, a matrix depletion and a change of the fiber alignment in the weld plane may occur which causes low weld strengths. Therefore, criteria for the successful welding were defined and various possibilities to optimize the weld strengths were investigated.

Full textAbstract:
Le contexte d'étude est celui de la Compatibilité ÉlectroMagnétique (CEM). L'objectif de la CEM est, comme son nom l'indique, d'assurer la compatibilité entre une source de perturbation électromagnétique et un système électronique victime. Or, la prédiction de ces niveaux de perturbation ne peut pas s'effectuer à l'aide d'un simple calcul analytique, en raison de la géométrie qui est généralement complexe pour le système que l'on étudie, tel que le champ à l'intérieur d'un cockpit d'avion par exemple. En conséquence, nous sommes contraints d'employer des méthodes numériques, dans le but de prédire ce niveau de couplage entre les sources et les victimes. Parmi les nombreuses méthodes numériques existantes à ce jour, les méthodes Multi-Domaines (MD) sont très prisées. En effet, elles offrent la liberté aux utilisateurs de choisir la méthode numérique la plus adaptée, en fonction de la zone géométrique à calculer. Au sein de ces méthodes MD, la " Domain Decomposition Method " (DDM) présente l'avantage supplémentaire de découpler chacun de ces domaines. En conséquence, la DDM est particulièrement intéressante, vis-à-vis des méthodes concurrentes, en particulier sur l'aspect du coût numérique. Pour preuve, l'ONERA continue de développer cette méthode qui ne cesse de montrer son efficacité depuis plusieurs années, notamment pour le domaine des Surfaces Équivalentes Radar (SER) et des antennes. L'objectif de l'étude est de tirer profit des avantages de cette méthode pour des problématiques de CEM. Jusqu'à maintenant, de nombreuses applications de CEM, traitées par le code DDM, fournissaient des résultats fortement bruités. Même pour des problématiques électromagnétiques très simples, des problèmes subsistaient, sans explication convaincante. Ceci justifie cette étude. Le but de cette thèse est de pouvoir appliquer ce formalisme DDM à des problématiques de CEM. Dans cette optique, nous avons été amenés à redéfinir un certain nombre de conventions, qui interviennent au sein de la DDM. Par ailleurs, nous avons développé un modèle spécifique pour les ouvertures, qui sont des voies de couplage privilégiées par les ondes, à l'intérieur des cavités que représentent les blindages. Comme les ouvertures sont, en pratique, de petites dimensions devant la longueur d'onde, on s'est intéressé à un modèle quasi-statique. Nous proposons alors un modèle, qui a été implémenté, puis validé. Suite à ce modèle, nous avons développé une méthode originale, basée sur un calcul en deux étapes, permettant de ne plus discrétiser le support des ouvertures dans les calculs 3D.

Full textAbstract:
Le bruit de cavité est un phénomène très fréquent dans le domaine des transports aériens.Il survient notamment lors de l'approche à l'atterrissage, où des interactions entre la cellule de l'aéronef et l'écoulement sont à l'origine de fortes émissions tonales. Il devient dès lors une source de pollution acoustique non-négligeable pour les populations résidant à proximité de zones aéroportuaires. Les études numériques et expérimentales décrites jusqu'à présent dans la littérature abordent essentiellement le cas des cavités rectangulaires. Pourtant, les cavités rencontrées en pratique dans l'industrie aéronautique impliquent des géométries souvent plus complexes. Lorsque ces cavités sont soumises à une excitation de nature aérodynamique, leur spécificité géométrique conduit le plus souvent à des réponses acoustiques assez éloignées des estimations issues de modèles académiques construits sur l'observation de cavités rectangulaires. Quelques travaux seulement abordent le cas des cavités cylindriques.Ce travail est consacré à l'étude aéroacoustique des cavités cylindriques, à l'initiative d'Airbus. Il s'inscrit dans le cadre du projet AEROCAV soutenu par la Fondation de Recherche pour l'Aéronautique & l'espace (FRAE). Son objectif est de déterminer les mécanismes impliqués dans les émissions acoustiques intenses et tonales pour les configurations étudiées.Une première partie présente les résultats expérimentaux issus des campagnes de mesures menées dans la soufflerie anéchoïque du Centre Acoustique du LMFA et de l'école Centrale de Lyon. Un modèle semi-empirique, reposant sur l'hypothèse d'une résonance acoustique pilotée par les instabilités présentes dans la couche de cisaillement à l'ouverture de la cavité,est construit à partir du modèle d'Elder (1978). Le modèle permet d'estimer les fréquences susceptibles de dominer l'acoustique rayonnée en champ lointain à partir de la donnée du champ moyen de vitesse longitudinale, que l'on mesure dans le plan de l'écoulement par Vélocimétrie par Imagerie des Particules (PIV).Une seconde partie est destinée au calcul direct du bruit rayonné par un écoulement laminaire ou turbulent affleurant une cavité cylindrique de référence. Il consiste à calculer le champ acoustique directement à partir de la résolution des équations tridimensionnelles de la mécanique des fluides. Le solver Alesia est présenté dans une version modifiée et adaptée à la mise en oeuvre d'une approche multidomaine d'ordre élevé faisant intervenir plusieurs maillages se recouvrant. Des techniques d'interpolation sont spécifiquement développées en vue d'assurer une communication bidirectionnelle entre les différents maillages, malgré des contraintes géométriques fortes. Un modèle d'excitation de l'écoulement est aussi développé afin de disposer de fluctuations dans l'écoulement incident, pour le cas turbulent. Ces deux points font l'originalité des calculs réalisés.Les simulations, menées sur une cavité de rapport d'aspect géométrique égal à 1 et soumise à un écoulement incident à Mach 0.2, montrent que le rayonnement acoustique peut être fidèlement reproduit numériquement. La couche de cisaillement est caractérisée par la présence de deux larges structures tourbillonnaires s'amplifiant lors de leur convection. Leur présence s'accompagne de fortes fluctuations de vitesse à l'origine d'un débit aérodynamique de fluide à l'ouverture qui excite la cavité acoustiquement. Une résonance forcée s'établit dans celle-ci, excitant la couche de mélange au voisinage du point de séparation. Ce couplage auto-entretenu est à l'origine du rayonnement acoustique intense et fortement tonal de la cavité. Il s'établit à une fréquence proche de la fréquence prédite par le modèle semi-empirique développé.

Full textAbstract:
Today, the main research field for the automotive industry is to find solutions for active safety. In order to perceive the surrounding environment, tracking nearby traffic objects plays an important role. Validation of the tracking performance is often done in staged traffic scenarios, where additional sensors, mounted on the vehicles, are used to obtain their true positions and velocities. The difficulty of evaluating the tracking performance complicates its development. An alternative approach studied in this thesis, is to record sequences and use non-causal algorithms, such as smoothing, instead of filtering to estimate the true target states. With this method, validation data for online, causal, target tracking algorithms can be obtained for all traffic scenarios without the need of extra sensors. We investigate how non-causal algorithms affects the target tracking performance using multiple sensors and dynamic models of different complexity. This is done to evaluate real-time methods against estimates obtained from non-causal filtering. Two different measurement units, a monocular camera and a LIDAR sensor, and two dynamic models are evaluated and compared using both causal and non-causal methods. The system is tested in two single object scenarios where ground truth is available and in three multi object scenarios without ground truth. Results from the two single object scenarios shows that tracking using only a monocular camera performs poorly since it is unable to measure the distance to objects. Here, a complementary LIDAR sensor improves the tracking performance significantly. The dynamic models are shown to have a small impact on the tracking performance, while the non-causal application gives a distinct improvement when tracking objects at large distances. Since the sequence can be reversed, the non-causal estimates are propagated from more certain states when the target is closer to the ego vehicle. For multiple object tracking, we find that correct associations between measurements and tracks are crucial for improving the tracking performance with non-causal algorithms.

Content Based Image Retrieval is an interesting and most emerging field in the area of
‘Image Search’, finding similar images for the given query image from the image
database. Current approaches include the use of color, texture and shape information.
Considering these features in individual, most of the retrievals are poor in results and
sometimes we are getting some non relevant images for the given query image.
So, this dissertation proposes a method in which we first pre-process the original image
based on different factors like edge, saturation, brightness, lightness etc, and then we will
perform some similarity test on each set and then find image that is overlapping
maximally at particular priority value, by taking all sets together, than display result.

Social Network Analysis (SNA) often involves huge amounts of information processing. Restricted by hardware capacity and execution time limits, it is difficult for clustering analysis to reflect the latest developments and changes in large social networks. This research, therefore, seeks to meet this demand in real-time transaction analysis. This study combines MapReduce and static overlap clustering methods to identify overlapping subgroups. Two new methods are proposed to enhance operational efficiency in data processing: Three-level MapReduce (TLM) and a highly dynamic overlap clustering method, with the latter being an extension of the former. Analysis results of paper citation networks show that, in terms of clustering quality and execution time, TLM is superior to the Clique Percolation Method (CPM). Furthermore, though the static TLM has better clustering quality than the highly dynamic overlap clustering method, the latter is more efficient in execution time.

Le présent mémoire est consacré à l'étude des chevauchements entre revendications territoriales autochtones. On s'y interroge sur l’origine et l’évolution de ces chevauchements ainsi que sur les mécanismes qui pourraient être employés pour trouver des solutions acceptables pour toutes les parties. Notre étude retrace d'abord l'évolution du critère d’exclusivité élaboré par les politiques et décisions judiciaires canadiennes relativement à l’octroi du titre autochtone, concluant que ce critère d’exclusivité est devenu un enjeu déterminant dans l’élaboration d’une solution relative aux chevauchements entre revendications territoriales. En observant la manière dont les différents paliers de gouvernement ont échoué dans leurs tentatives de solutionner les enjeux de chevauchement, nous constatons que les traditions juridiques autochtones doivent être intégrées à la résolution des conflits et à l’interprétation du critère d’exclusivité. Ceci exige de percevoir l’institution juridique de la résolution de conflits selon une certaine vision du droit. Nous utilisons ici celle de Lon Fuller, qui présente une approche permettant de réconcilier plusieurs traditions juridiques. Notre étude nous conduit à proposer le système du Indigenous Legal Lodge comme mécanisme de résolution de conflit permettant aux autochtones de faire appel à leurs traditions juridiques dans la résolution des chevauchements, permettant ainsi de réconcilier ces traditions diverses.This thesis is dedicated to the study of overlapping aboriginal land claims. We question the origin and evolution of these overlaps and study the mechanisms which could be used in order to determine a solution acceptable to all parties. Our study first discusses the evolution of the exclusivity criterion developed in Canadian policy and case law relating to the granting of an aboriginal title, concluding that the criterion of exclusivity has become a defining issue in the development of a solution to overlaps between land claims. By observing the failures of the various levels of government in their attempts to develop solutions to overlapping claims, we find that Aboriginal legal traditions must be integrated into conflict resolution and be used when interpreting the exclusivity criterion. This requires us to perceive conflict resolution, as a legal institution, according to a certain understanding of the law. We use Lon Fuller’s vision, who presents an approach for reconciling various legal traditions. Our study brings us to propose the Indigenous Legal Lodge as a conflict resolution mechanism enabling Aboriginal groups to call upon their own legal traditions in resolving overlaps and to reconcile their differing traditions.

In realistic, complex manufacturing systems, the use of operation research techniques to formulate a mathematical model to schedule an operational sequence is probably difficult because of complexity and variation. This study presents an ant colony optimization (ACO) heuristic for establishing an effective and simple mechanism to solve the problem of scheduling associated with overlap manufacturing operations. Network structuring and recursive calculation methods were used to determine the mechanism. In the proposed approach, the scheduling mechanism and ACO heuristics are developed separately, improving the performance of the overlap manufacturing flow by varying parameters or settings within the ACO’s heuristic and enabling the application to be flexibly modified by altering the scheduling criterion. Finally, the results showed that ACO heuristic had a good search for answers performance and analysis on the efficiency and the robust.

This paper analyzes the long-term dynamic effect of demographic change on international capital movement between Taiwan and Japan, by constructing a two-country multi-period overlapping generation model. In a closed economy setting, the simulation results illustrate that population aging has an adverse effect on saving motive and induces heavier fiscal burdens to the government under pay-as-you-go pension system. Considering the demographic change and existing welfare system, pension reform and tax reform play important roles on improving the government deficits and individuals’ saving behavior due to population aging. In an open economy setting, the simulation results indicate that aging leads to a reduction in savings in both countries. Besides, capital moves from aged economy to aging economy, namely, from Japan to Taiwan. However, fiscal policy does not only have direct effect on individual economic behavior, but also affects current account and trade balance indirectly. Finally, this study shows the impact of population aging on macroeconomics and its effect on international capital flow.

Data hiding (DH) is a significant research field which combines cryptography and digital multimedia processing. DH can widely used in digital multimedia, especially digi-tal images. Matrix code DH (MCDH) by covering function is based on error correcting code, which has high embedding efficiency, and meanwhile decreases the number of modified bits. Up to date, there are already MCDHs proposed. Most researches on MCDH uses using Hamming code, BCH code, and Golay code. A we-known MCDH is based on Hamming coding HC(n, k), by covering function COV(1, n = 2k − 1, k), which is referred to as HDH. Afterwards, Hamming+ 1 DH (H1DH) was introduced, and it had a better embedding efficiency when compared with HDH. Consider DH on pixel domain. MCDH has a great relation with Least Significant Bit (LSB) and Optimal Pixel Adjustment Process (OPAP). In fact, these methods are very similar, but use different ways for modifying bits. In this thesis, we propose Hamming+k DH (HkDH) and Hamming+k with m over-lapped pixels DH (Hk_mDH) which integrate the approaches of LSB, OPAP, and H1DH. HkDH may embed 2k secret bits in n pixels. It uses LSB substitution when embedding the first k bit, and then modified 2nd LSB when embed the second k bits. Modifying the 2nd LSB may have collision problem, we can use OPAP to solve it. On the other hand, Hk_mDH embeds 2k bits in (2n – m) pixels. It uses LSB substitution when embed the first k bits. When embedding the second k bits, the modifications in overlapped pixels adopt OPAP. The modifications in other (n – m) pixels still use LSB substitution. For Hk_mDH, we decrease modifications but reduce embedding capacity due to m over-lapped pixels.

Short product development lead time is one of the most important competitive advantages in TFT-LCD industry. Design Verification Testing (DVT) process accounts for much of this lead time. In this research, we propose a new DVT process by overlapping some of the activities to shorten the product development lead time. In addition, we develop mathematical models to evaluate the expected DVT times of both original and overlapped DVT processes as well as the probability of inventory lost for the overlapped process. By comparing the expected product development lead times of these two processes against the risk of inventory loss of the overlapped process, the company can evaluate the benefit of adopting the overlapped process against its potential risks. Three product types are studied to determine the conditions under which the overlapped process is preferred. Once the overlapped process is adopted, the optimal date to release production order for front-end process is also studied.

Due to single camera finite surveillance, using amount of overlapping multi-cameras to monitor region cannot satisfy the demand of wide region video surveillance in the considerations of economic and computational aspects. In recent years, messages transformation and fusion of moving object in non-overlapping multi-cameras have become popular research in video surveillance. The difficult part of target tracking in non-overlapping multi-cameras is the spatial discontinuous of cameras, the difference of setting angles and environment of camera. Besides, people are non-rigid objects; it’s difficult for cameras to do object matching because of the external condition and the inherent psychological impact. In this thesis, we propose an integrated system by using non-overlapping multi-cameras for different brightness and viewing angles environments to long-range tack object. The first thing is to detect the moving objects by Gaussian Mixture Model (GMM), shadow removal and morphological etc. preprocess, and then adoptive blob intersection to track moving objects. In order to deal with the objects occlusion case , we use mean shift algorithm with Kalman filter to track these moving objects. In training phase, setting up the link relation of cameras manually by the observer and using a number of known pair objects across different field of views continuously to statistics and estimate the Gaussian distribution of travel time of the objects across blind region, and further obtain the maximum/minimum travel time of the object moving through the blind region, and using cumulative BTF to get the brightness relation between different field of views. After calibrating the color of object by BTF, extract the major color of object to be the feature of object ; then combine the estimated time relation to select likely objects and match the feature of objects. For the experiment part, we use the scenes of different illustration and view angle to analyze, such as two cameras set indoor hallway and outdoor square, three cameras set indoor hallway. The system based on the proposed method can identify objects with the accuracy of 97.5% for two cameras set indoor hallway, 94.4% set outdoor square, and 94.6% for three cameras set indoor hallway. The frame rate is about 15 to 30 fps.

Many community detection algorithms have been proposed, but most of them are focused on the disjoint community sets. However, communities are often overlapped with each other in real networks. In order to find the overlapping community structures, we proposed a new method based on modularity maximization. Since the modularity values of fuzzy partitions are not large enough, that makes the overlapping community structures undetectable. To overcome this problem, a method is introduced by setting the sum of a node distributed overlapping weights larger than one, such that the modularity values of fuzzy partitions are increased too. That makes overlapping communities detectable by maximizing modularity values. Then, the overlapping community detection problem is considered as a node weight allocation problem (NWA_OCD), the overlapping communities could be detected by solving the NWA_OCD problem. In experiments, our method is applied on both synthetic and real networks. The results show that our method can detect the heavily overlapping nodes which might be ignored by other algorithms.

With the explosive increase of the amount of information in recent years, the research on the big data has become an inevitable topic of the research. How to mine the information which we are interested in and use it a lot will become a really important and necessary issue. Looking for the spatial co-location pattern that appears frequently nearby over an incremental database also becomes an interesting and essential topic. An incremental database refers to the fact that the entire database becomes larger after the data has been inserted or deleted over time in the original database. It can be widely used in many areas due to the changes in data over time, including the location-based services (LBS), environmental ecology, and also the business behavior patterns. In this project, we only consider the insertion of the data. Many spatial co-location pattern mining approaches are for traditional spatial databases. Therefore, they do not need to consider candidate instances generated and update their participation index in the process. Yoo et al. have proposed the EUCOLOC algorithm to mine co-location patterns in the incremental database. This method may record the duplicated data both in the original database and the incremental database during inserting the new data. They generate many candidate instances, and then delete some of these candidate instances by checking whether their subsets exist or not. Finally, they update the participation index in the process and update co-location patterns. However, this method not only needs large storage to store points in the database and their relationships with each other, but also generates many unnecessary candidate instances (eg, non-incremental candidate instances). In this project, we plan to propose the non-overlapping approach to mine the colocation patterns for incremental database. The non-overlapping algorithm refers to the situation that can avoid duplicated edges recorded in the original and incremental database. In other words, no edge will be recorded in the original database when it is recorded in the incremental database. First, we plan to propose approach that rearrange the relations by the asterisk annotation priority in order to use less storage to store data information and also can avoid generating the non-incremental candidate instances. Second, we plan to check the relation of the subset before generating size-k candidate instances. In this way, we can avoid generating non-clique instances completely. Therefore, our method, which expect to avoid generating non-incremental candidate instances and non-clique candidate instances, as well as to avoid storing duplicate data, resulting in better performance of spatial co-location pattern mining.

Packaging is an important element responsible for brand growth and one of the main rea-sons for producers to gain competitive advantages through technological innovation. In this re-gard, the aim of this work is to design a fully autonomous electronic system for a smart bottle packaging, being integrated in a European project named ROLL-OUT. The desired application for the smart bottle is to act as a fill-level sensor system in order to determine the liquid content level that exists inside an opaque bottle, so the consumer can exactly know the remaining quantity of the product inside.
An in-house amorphous indium–gallium–zinc oxide thin-film transistor (a-IGZO TFT) model, previously developed, was used for circuit designing purposes. This model was based in an artificial neural network (ANN) equivalent circuit approach.
Taking into account that only n-type oxide TFTs were used, plenty of electronic building-blocks have been designed: clock generator, non-overlapping phase generator, a capacitance-to-voltage converter and a comparator. As it was demonstrated by electrical simulations, it has been achieved good functionality for each block, having a final system with a power dissipation of 2.3 mW (VDD=10 V) not considering the clock generator. Four printed circuit boards (PCBs) have been also designed in order to help in the testing phase.
Mask layouts were already designed and are currently in fabrication, foreseeing a suc-cessful circuit fabrication, and a major step towards the design and integration of complex trans-ducer systems using oxide TFTs technology.
