Recently, flexible needles with bevel tips for percutaneous intervention have attracted significant interest. However, there are remaining problems related to controlling by duty-cycle algorithm which prevents widespread adoption of this technology. This motivates development of a new steerable flexible needle model that can change its curvature without axial rotation. In this paper, we propose a...
A motion capture system requires a collection of human body model data which reflect body features of a user. The existing motion capture systems utilize human body model data with fixed body proportions; or require manual input of human body model data, which is unwieldy. This paper proposes how to measure the length of body joints using the Kinect's depth sensor, and how to put the measured value...
GPR models are instrumental in improving procedures of signal processing and developing indicators for GPR data interpretation. The paper presents GPR models of basic types of geostructural discontinuities in alluvial placers of Yakutia. Frozen rock massif of placer deposits is characterized by layered structure and includes discontinuities related to disturbance of rock, relict streams, and boulder...
A hybrid differential evolution-binary particle swarm optimization (DE-BPSO) algorithm is proposed as a feature selection algorithm in the development of quantitative structure-activity relationship (QSAR) models. DE is used to evolve the velocities of the particle swarm from which a series of rules are used to determine the discrete values of the position vectors which form chemical descriptor subsets...
Because biological systems with high-throughput performance generate huge amount of experimental data, biologists need efficient methods to analyze large datasets. Specifically, researchers in systems biology require the ability to compare and integrate complex data from different omics' experiments. This requirement results in the standardization of formats for data representation and communication...
Starburst Amacrine Cells (SACs) play a major role in the detection of directional motion in the biological retina. The starburst amacrine cell has intrinsic electrical mechanisms for producing directional selectivity (DS). GABA transmitter-receptor interactions between two overlapping SACs make DS more robust. We present a compartmentalized CMOS neuro-morphic circuit that models a portion of two biological...
For our present life anytime, anywhere access to the network can communicate with the ubiquitous computing. it is essential to human life. We should be able to agree that communication will be enabled. For our present life, anytime, anywhere access to the network can communicate with the ubiquitous computing. Such as the ubiquitous era approached, interaction between the user and the computer has...
The aim of our research is to provide a better understanding of the technical differences between the functional solutions for satellite-based tolling in Europe. In addition our research is aimed at evaluating the processing requirements and communication load among three tolling entities, namely: the European Electronic Toll Service, a Toll Charger and On-Board Equipment. Three functional solutions...
Brain recording and stimulating systems are of major importance in neuroscience. They include an electrode or an array of electrodes, at the neuro-electronic interface. The electrodes NEX 100 and MS 306 are commonly used for accurate placement in deep sites of rats' brain, but few characterization data are available. After considerations related to the interface electrical model, this paper exposes...
Today's molecular biology is confronted with enormous amounts of data, generated by new high-throughput technologies, along with an increasing number of biological models available over web repositories. This poses new challenges for bioinformatics to invent methods coping with incompleteness, heterogeneity, and mutual inconsistency of data and models. To this end, we built the library BioASP, providing...
In this paper, we outline the Grid 2.0 Research, a collaborative Smart Grid research program between Gachon Energy Research Institute (GERI) of Kyungwon University and Bell Labs of Alcatel-Lucent. Salient features of the Grid 2.0 Research are the active role of distributed fixed and mobile energy storage, distributed renewable energy sources, and active load-side participation. Our focus is not on...
With the growing pursuit of leisure and health in life, the goods and services of the traditional beauty industry produce a great impact due to the aromatherapy has different levels of approach to cosmetology and health protection. In response to the typical industrial styles of aesthetic economy and experience economy times, Spa industry not only requires high-quality service system, but also relies...
A direct shipment via express courier is expected to be an area with huge sales potential in the near future. In Korean market, many domestic companies of various sizes have been fiercely competing to extend their own market share. Currently offering only international delivery services, moreover, foreign companies with a higher level of customer services are expected to escalate the competition by...
We present a background model that differentiates between background motion and foreground objects. Unlike most models that represent the variability of pixel intensity at a particular location in the image, we model the underlying warping of pixel locations arising from background motion. The background is modeled as a set of warping layers, where at any given time, different layers may be visible...
Digital Human Model (DHM) plays an important role in the design field. And how to make a static DHM into a dynamic model would be a critical issue for the application. Anthropometric landmarks are easily visualized by showing the landmark locations on the body. It is a natural extension to create 3D illustrations of the landmarks by placing then on 3D computer generated bodies. Our goal was to create...
This paper presents a scalable hierarchical architecture for accelerating simulations of large-scale biological neural systems on FPGA-based platforms. The architecture provides a high degree of flexibility to optimize the parallelization ratio based on available hardware resources and model specifications such as complexity of dendritic trees. The proposed addressing scheme, design modularity and...
Generally, 3D finite element method (FEM) is applied to consider overhang conditions of Linear Induction Motor (LIM). This paper suggests coupling algorism of 3D FEM and electro-magnetic field theory (EMFT) to overcome long analysis time of 3D FEM and to optimize its secondary structure. The optimized model is manufactured and the experimental results are compared to demonstrate the validity.
We demonstrate the application of a Model-Driven Software Development (MDSD) methodology using the example of an analysis framework designed for a data logging device in the field of vehicle testing. This mobile device is capable of recording the data traffic of automotive-specific bus systems like Controller Area Network (CAN), Local Interconnect Network (LIN), FlexRay and Media Orientied Systems...
As delivering contents has become the dominant usage of Internet, the efficient content distribution is being one of the hottest research areas in network community. In future network, it is anticipated that network entities such as routers will be equipped with in-network storage due to the trend of ever-decreasing storage cost. In this paper, we propose a novel content delivery architecture called...
We have demonstrated that gold nanoparticles (AuNPs) can effectively associate with enzyme through spontaneous adsorption to afford supramolecular complexes, resulting in a significant increase of its enzymatic activity. In this work, we embarked on a study of the interactions between the different-sized AuNPs and the substrate through quantifying the kinetic parameters (Kcat and KM). The diversity...
