Visualization tools play an important part in assisting analysts in the understanding of networks and underlying phenomena. However these tasks can be hindered by visual clutter. Simplification/decimation schemes have been a main alternative in this context. Nevertheless, network simplification methods have not been properly evaluated w.r.t. their effectiveness in reducing complexity while reserving...
NHK has proposed a famous 3D audio system: 22.2 multi-channel system, but its loudspeakers are too many and are troublesome to put in home. Ando and Wang has proposed two simplification methods to reduce its channel number, but only 3D sound field at the central listening point can be recovered well by NHK 22.2 system and its simplified systems, the listening experience at a non central listening...
Essential image processing and analysis tasks, such as image segmentation, simplification and denoising, can be conducted in a unified way by minimizing the Mumford-Shah (MS) functional. Although seductive, this minimization is in practice difficult because it requires to jointly define a sharp set of contours and a smooth version of the initial image. For this reason, various relaxations of the original...
The IEC 62305, which was published 10 years ago, has fundamentally changed the structure of planning lightning protection [1]. The method determined in the standard — which requires a detailed risk assessment for each and every structure — has made the standard user's task more difficult due to the vast amount of parameters. Meantime many criticism, application examples and explanations of the risk...
Since 2006, Red Tape has been a hot topic for the European Commission. All the European Countries agreed in reducing the costs that enterprises have to face due to Administrative Burdens (AB). Each Country has implemented his own simplification plans in order to move from the Red Tape to better regulation. Trentino's local governments both 1) issued laws to cut down the total amount of information...
The efficiency and accuracy loss are the key issues for the point cloud simplification. In this paper, a feature preserving algorithm is proposed for point cloud simplification based on hierarchical clustering with the surface feature description. The surface variation is presented as the main criterion for the efficient hierarchical clustering method to simplify the mass and dense point cloud fast,...
Although deep compositional features have achieved an amazing performance in many application scenarios, it is not easy for them to directly tackle big data case due to their high computing time and memory usage. This paper presents a comparative evaluation for the simplification of deep compositional features by exploring the existing vector quantization and binarization techniques. Different techniques...
Node occlusion and edge congestion problems, which are caused by the increasing scale and complexity of network, had become a hot spot in network visualization research. To solve the visual clutter problem in network, edges close to each other in network were bundled by curving them. A segmental forced-directed algorithm (FDA) simplification model and a community based compatible edge bundling network...
We have evaluated Ga-Sn-O (GTO) films fabricated using mist chemical vapor deposition (CVD). First, it is found that the GTO films are roughly transparent. Moreover, as the deposition temperature decreases, the transmittance becomes higher. Next, it is found that even if the carrier gas speed changes, the sheet resistance is roughly the same. However, as the composition ratio in the material solution...
We are developing cellular neural networks using thin-film transistors (TFTs). Although simplification of the circuits for the neurons and synapses is also needed for the cellular neural network, the detailed discussion is not sufficient for the cellular neural network. Particularly in this study, we tried simplification of synapse devices. We used discrete trimmer resistors and capacitors for the...
We are developing cellular neural networks using thin-film transistors (TFTs). Although simplification of the processing elements such as neurons and synapses is also needed for the cellular neural network, it is difficult and time-consuming to fabricate and evaluate actual devices. Therefore, we are studying the simplification of the processing elements in the neural networks by using circuit simulation...
Enterprise architectures at the best of financial institutions are not necessarily a result of choice, but are patch work quilts developed over time, sometimes decades, with multitude of technologies, while responding to business needs at any given point in time. The various lines of business at financial institutions run in silos creating unwanted complexity and duplication. Mergers & acquisitions...
Aiming at point cloud simplification often loses too many feature details, a simplification method for massive unstructured point cloud is proposed to preserve the geometrical and features. Firstly, the normal vector of the data points is calculated, and the feature points are calculated by position and curvature of the data points. Sharp feature points and edge feature points which are extracted...
In this paper, we propose an improved quadric error metrics algorithm based on triangle strips which raises the speed of compression and keeps the features of the appearance of cultural relics well. We also establish the hierarchical model of gradual transmission, which resolves the problem of undesirable high time expenses when transmitting the artifact model. In the first place, triangle strips...
In this paper, we propose a novel scheme for simplifying a surfel set with the resultant surfels computed and distributed to preserve prominent geometric and textural features. It works by iteratively collapsing local neighborhoods around surfels until a given data reduction ratio is reached. For optimized feature preservation, novel techniques are proposed in various steps of the scheme. The local...
The typical Online Handwritten Text Recognition System contains four main phases which are: preprocessing, feature extraction, recognition, and post-processing phases. Preprocessing phase aims to reduce or remove imperfections caused during acquisition step. This phase is also used to minimize handwriting variations irrelevant for pattern classification which may exist in the text acquisition. The...
Photovoltaic (PV) generation is increasingly popular in power systems. The nonlinear dependence associated with a large number of distributed PV sources adds the complexity to construct an accurate probability model and negatively affects confidence levels and reliability, thereby resulting in a more challenging operation of the systems. Most probability models have many restrictions when constructing...
During the past decade, much effort has been invested in developing standards to overcome data and software interoperability barriers in the oil and gas industry. Whereas syntactical integration is no longer problem, semantic integration still remains an open challenge. To overcome this problem, standards provide more and more complex structures to capture the semantics of different domains. As standards...
Virtual worlds and games increasingly deliver 3D meshes over the Internet using instanced file formats, such as COLLADA. However, existing simplification algorithms do not account for instancing in their inputs, operating instead on triangle soups or indexed triangle meshes. This makes them unsuitable for highly instanced meshes, since expanding an instanced mesh to an indexed triangle mesh and then...
A recently proposed method for the simplification of single variable systems having ordinary polynomial denominators has been extended to the multivariable case encompassing situations where the original or simplified model may have delays in their states. The performance index used for optimization is the integral of the time-weighted squared error between the responses of the original and simplified...
