An improvement method of wall points extraction process from mobile mapping system data by localization method of space division

A purpose of our research is to generate three-Dimensional (3D) building models since they are always the most important elements for landscape simulation and urban planning. The authors have proposed an extraction method for individual building wall points from a Mobile Mapping System data as the first step for generating the virtual space. However, this wall points extraction method has some problems. For example, it might extract undesirable planes which are different from walls of buildings and it is also time-consuming for extracting small planes by using Random Sample Consensus (RANSAC). This paper gives the reason why the RANSAC in our system extracts undesirable planes under influence of the structure which are far away from it, and also show the reason that the inlier ratio becomes lower as the plane extraction process goes on. To solve these problems, the authors proposed the idea of localizing the extracting target from the influence factors which are far away from the target. It shows that this method has highly improved the extraction results as well as largely reduced the processing time.

Analyzing Harmonic Monitoring Data Using Data Mining

Harmonic monitoring has become an important tool for harmonic management in distribution systems. A comprehensive harmonic monitoring program has been designed and implemented on a typical electrical MV distribution system in Australia. The monitoring program involved measurements of the three-phase harmonic currents and voltages from the residential, commercial and industrial load sectors. Data over a three year period has been downloaded and available for analysis. The large amount of acquired data makes it difficult to identify operational events that impact significantly on the harmonics generated on the system. More sophisticated analysis methods are required to automatically determine which part of the measurement data are of importance. Based on this information, a closer inspection of smaller data sets can then be carried out to determine the reasons for its detection. In this paper we classify the measurement data using data mining based on clustering techniques which can provide the engineers with a rapid, visually oriented method of evaluating the underlying operational information contained within the clusters. The paper shows how clustering can be used to identify interesting patterns of harmonic measurement data and how these relate to their associated operational issues.
Research on multidimensional analysis method of drilling information based on Hadoop

Drilling data shows the features of a large number, various types and dispersing. To make drilling decisions, these features can not support the analysis of multidimensional rapidly and effectively. Based on the HADOOP architecture, this paper puts forward a method of using the Apache Kylin framework in the multidimensional analysis of drilling information. In a BIG DATA environment, the optimization of cube model precomputation and technical proposal of inquiry processing in multidimensional analysis is discussed, which provides an effective way for multidimensional analysis of oil drilling information.
A 9-16Gb/s clock and data recovery circuit with three-state phase detector and dual-path loop architecture

This paper describes the design and fabrication of a clock and data recovery circuit. This clock and data recovery circuit utilizes a novel half-rate three-state phase detector. The proposed phase detector is fully symmetric and has low propagation delay that makes it attractive for high speed applications. The proposed clock and data recovery circuit also implements a novel half-rate frequency detector. This frequency detector automatically remains disabled during the locked state. The proposed CDR circuit implements dual-path loop architecture. The dual path architecture suppresses the jitter peaking. The proposed clock recovery system is fabricated in a CMOS 0.18/spl mu/m technology. Measurements show that the CDR is functional for a data rate in the range of 9-16GHz. The circuit, including the output buffers, dissipates 310mW power from a 1.8V power supply for a 16Gb/s input data rate and 250mW power for a 10Gb/s input data rate. The peak-to-peak jitter of the recovered clock oscillating at 5 GHz and 8GHz are 10ps and 14ps, respectively. The effective die size is 1mm /spl times/ 0.8mm.

EXPERIMENTAL OBSERVATION OF MICROCRACKING OF COMPOSITE LAMINATES UNDER CRYOGENIC TEMPERATURE

The objective of this work was to develop a predictive capability for the onset of ply failure in composite laminates subjected to combined thermal and mechanical loads. The material system studied was a carbon fiberreinforced toughened epoxy composite, IM7/5250-4. Thermomechanical properties required for the analysis were obtained from tests on unidirectional laminates. These laminates were tested at 73°F and -321°F. Coefficients of thermal expansion (CTE) were measured using strain gages, over the temperature range of 300°F to -321°F (liquid nitrogen). Laminates, [0/902/0]T? [0/903/0]T, [02/902]s? and [30/-30/90]s> were used to experimentally determine the onset of ply failure under mechanical and thermal loads. The onset of ply failure was detected from acoustic emission and incremental loading and unloading experiments, and confirmed from microscopic examination of polished specimen edges. Ply stresses were calculated for the corresponding conditions from laminated plate theory, using the appropriate experimentally generated thermomechanical properties and the applied load. The maximum stress failure theory was applied to predict failure. Transverse tensile strength increased at lower temperatures, while strain to failure decreased (indicating increased brittleness). The stress level at the onset of ply failure decreased significantly at lower temperatures, mainly due to an increase in the curing residual stresses. Lamination theory in conjunction with the maximum stress failure criterion tends to overestimate the onset of the transverse cracking in the laminates considered.
Past and present mercury accumulation in the Lake Baikal seal: Temporal trends, effects of life history, and toxicological implications

Despite global efforts to reduce anthropogenic mercury (Hg) emissions, the timescale and degree to which Hg concentrations in the environment and biota respond to decreased emissions remain challenging to assess or predict. In the present study we characterize long‐term trends and life‐history patterns in Hg accumulation and toxicological implications of Hg contamination for a freshwater seal from one of the world's largest lakes (Lake Baikal, Siberia, Russia) using contemporary tissues and archival teeth. Stable isotope analysis and Hg analyses of soft tissues (muscle, liver, kidney, blood, brain, heart) and teeth from 22 contemporary seals revealed rapid changes in diet and Hg accumulation in the first year of life with a stable diet and increase in tissue Hg throughout the rest of life. Although maternal transfer of Hg was an important source of Hg to seal pups, reproduction and lactation by female seals did not appear to result in sex‐related differences in Hg concentrations or age‐related accumulation in adult seals. Based on Hg analysis of archival teeth (n = 114) and reconstructed values for soft tissues, we also assessed temporal trends in seal Hg between the years 1960 and 2013. Seal Hg concentrations in hard (teeth) and soft (e.g., muscle, liver) tissues were highest in the 1960s and 1970s, followed by a decrease. The decline in seal Hg concentrations in recent decades was most likely driven by a reduction in Hg inputs to the lake, suggesting that global and regional efforts to reduce Hg emissions have been successful at reducing ecosystem and human health risks posed by Hg in Lake Baikal.

Practical secrecy-preserving, verifiably correct and trustworthy auctions

We present a practical system for conducting sealed-bid auctions that preserves the secrecy of the bids while providing for verifiable correctness and trustworthiness of the auction. The auctioneer must accept all bids submitted and follow the published rules of the auction. No party receives any useful information about bids before the auction closes and no bidder is able to change or repudiate her bid. Our solution uses Paillier's homomorphic encryption scheme [25] for zero knowledge proofs of correctness. Only minimal cryptographic technology is required of bidders; instead of employing complex interactive protocols or multi-party computation, the single auctioneer computes optimal auction results and publishes proofs of the results' correctness. Any party can check these proofs of correctness via publicly verifiable computations on encrypted bids. The system is illustrated through application to first-price, uniform-price and second-price auctions, including multi-item auctions. Our empirical results demonstrate the practicality of our method: auctions with hundreds of bidders are within reach of a single PC, while a modest distributed computing network can accommodate auctions with thousands of bids.
Epsilon-near-zero modes for tailored light-matter interaction

Epsilon-near-zero (ENZ) modes arising from condensed-matter excitations such as phonons and plasmons are a new path for tailoring light-matter interactions at the nanoscale. Complex spectral shaping can be achieved by creating such modes in nanoscale semiconductor layers and controlling their interaction with multiple, distinct, dipole resonant systems. Examples of this behavior are presented at midinfrared frequencies for ENZ modes that are strongly coupled to metamaterial resonators and simultaneously strongly coupled to semiconductor phonons or quantum-well intersubband transitions (ISTs), resulting in double- and triple-polariton branches in transmission spectra. For the double-polariton branch case, we find that the best strategy to maximize the Rabi splitting is to use a combination of a doped layer supporting an ENZ feature and a layer supporting ISTs, with overlapping ENZ and IST frequencies. As a result, this design flexibility renders this platform attractive for low-voltage tunable filters, light-emitting diodes, and efficient nonlinear composite materials.
Robust translational/rotational eye-vergence visual servoing under illumination varieties

To track moving target, keep it at the center of the camera's view and overcome the defects of fixed hand-eye visual servoing system, we proposed an eye-vergence visual servoing system. In the new system, left and right cameras' directions could be rotated to observe and keep the target object to be seen at the center of camera images to reduce the influence of aberration of a camera lens. In practical applications among different indoor environments, lighting conditions may vary greatly. Therefore, the hue of HSV and model-based matching method are utilized to detect an object in the eye-vergence system. In this paper, it is carried out that comparison and analysis of recognition experiments in different illumination. Through the interior illumination changing experiment it can be ensured that the recognition method has a robustness to illumination changing within a certain range. And in the end, through a 3D pose tracking experiment, it can be verified that the tracking is still carried out smoothly even though illumination of object frequently changes.
Design, Modeling, and Performance Analysis of Multi-Antenna Heterogeneous Cellular Networks

This paper presents a stochastic geometry-based framework for the design and analysis of downlink multi-user multiple-input multiple-output (MIMO) heterogeneous cellular networks with linear zero-forcing transmit precoding and receive combining, assuming Rayleigh fading channels and perfect channel state information. The generalized tiers of base stations may differ in terms of their Poisson point process spatial density, number of transmit antennas, transmit power, artificial-biasing weight, and number of user equipments served per resource block. The spectral efficiency of a typical user equipped with multiple receive antennas is characterized using a non-direct moment-generating-function-based methodology with closed-form expressions of the useful received signal and aggregate network interference statistics systematically derived. In addition, the area spectral efficiency is formulated under different space-division multiple-access and single-user beamforming transmission schemes. We examine the impact of different cellular network deployments, propagation conditions, antenna configurations, and MIMO setups on the achievable performance through theoretical and simulation studies. Based on the state-of-the-art system parameters, the results highlight the inherent limitations of baseline single-input single-output transmission and conventional sparse macro-cell deployment, as well as the promising potential of multi-antenna communications and small-cell solution in interference-limited cellular environments.
BST-based low temperature co-fired ceramic (LTCC) modules for microwave tunable components

The recent trend in low temperature co-fired ceramic (LTCC) technology is to integrate more elements into multilayer modules. This thesis describes work specifically aimed at developing ferroelectric barium strontium titanate (BST) for integration into such modules. In particular, an objective was the development of a novel, electric field controlled, tunable component to be used at microwave frequencies (2-26 GHz). For the application envisaged, relative permittivity is required to be low (100-1000) and adjustable by a suitable applied electric field, the dissipation factor at room temperature must be low (~0.001) at 2-26 GHz, and most importantly, the sintering temperature must be suited to the LTCC technology (~900 °C) Initial work was focused on sol-gel derived Ba0.7Sr0. 3TiO3 powders with boron oxide addition, which were sintered at 900 °C, the dissipation factor was 0.006. The dissipation factor was not low enough for the desired microwave application, and attention turned to powders prepared by the mixed-oxide route. The Ba0.7Sr0. 3TiO3 powders, fluxed with the optimum amounts of boron oxide and lithium carbonate, could be sintered at 890 °C to the same density as is achieved with un-fluxed Ba0.7Sr0. 3TiO3 sintered at 1360 °C. The dissipation factor for this fluxed powder was acceptably low, although permittivity was too high for the particular objective. Subsequently, research was on BST modified by magnesia, 0.4Ba0. 55Sr0.45TiO3-0.6MgO (BSTM). With the optimum fluxing additives, the sintering temperature necessary to achieve a dense BSTM-based ceramic was reduced to 950 °C. The developed microstructure was good, and the relative permittivity and dissipation factor values (221, 0.0012 at 1 kHz) at room temperature indicated good microwave properties. Studies were also undertaken with organic-based tape-casting slurries, laminating procedures and burn-out and sintering schedules. Several kinds of tapes were fabricated and characterized. A test structure for the measurement of dielectric properties at 26 GHz of the optimized BSTMbased ceramic was constructed. The specimen was 50 μm thick layer of BST on an alumina substrate. The relative permittivity and tunability were 130 and >15 % at 4 V μm-1 at room temperature. A tunable phase-shifter was fabricated from the same BSTM-based tape using a novel gravure printing technique, and measurements at 26 GHz showed phase shift from 10 to 35° when the electric field was increased from 1 V μm-1 to 2.5 V μm-1. Some exploratory experiments are described to assess the compatibility of the developed BSTbased LTCC with commercial LTCC and some electroceramics.
Managing shared resource pools for enterprise applications

The thesis presents a comprehensive management approach for shared resource pools that enables the efficient use of server resources while managing the resource access quality offered to workloads. The approach includes controllers that operate at three levels. A workload placement controller globally allocates and consolidates workloads based on historical demands. To improve resource access quality, a migration controller continuously observes the resource pool and migrates workloads between servers in order to decrease the duration of quality violations. Each server has a workload manager that locally optimizes resource allocation. A resource pool simulator models the placement of workloads, simulates the competition for resources, causes controllers to execute according to management policies, and dynamically adjusts placements and configurations. A case study shows that fully integrated controllers outperform the separate use of controllers or loose integrations.
Nanofabrication of halloysite-PCL composite scaffolds and functionalization of titanium for tissue regeneration

Major medical needs may be achieved through regenerative medicine. Nanotechnology has triggered a research revolution in many important areas such as the biomedical sciences and bioengineering at the molecular level which has grown significantly due to the availability of new analytical applications and tools based on nanotechnology. Clinical conditions and diseases being targeted by nanotechnology research include burns, Alzheimer's and Parkinson's disease, implant failure, improved wound healing, birth defects, osteoporosis and congestive heart defects. Therapeutic use of growth factors and drugs to stimulate the production and/or function of endogenous cells represents a key area of regenerative medicine. The development of methods to expand ex vivo and drug delivery through advances in cell culture and scaffold technology have led to successful new treatment modalities for bone and wound repair. The studies in this dissertation focused on several regenerative medicine approaches, with a future goal of an implantable scaffold material that can efficiently act as a repair material for wound healing and repair or as a replacement material for bones, teeth and other tissues. In this study, two different materials were nanoengineered for regenerative medicine applications. Anodization was used to produce nanoporous titanium scaffolds. Electrospinning was used to form Poly (e-caprolactone) (PCL) scaffolds, halloysite-PCL composite scaffolds and drug loaded halloysite-PCL scaffolds. Cellular response was assessed in each study through cell-based assays, including the
Contrast gain control and retinogeniculate communication

Visual information processed in the retina is transmitted to primary visual cortex via relay cells in the lateral geniculate nucleus (LGN) of the dorsal thalamus. Although retinal ganglion cells are the primary source of driving input to LGN neurons, not all retinal spikes are transmitted to the cortex. Here, we investigate the relationship between stimulus contrast and retinogeniculate communication and test the hypothesis that both the time course and strength of retinogeniculate interactions are dynamic and dependent on stimulus contrast. By simultaneously recording the spiking activity of synaptically connected retinal ganglion cells and LGN neurons in the cat, we show that the temporal window for retinogeniculate integration and the effectiveness of individual retinal spikes are inversely proportional to stimulus contrast. This finding provides a mechanistic understanding for the phenomenon of augmented contrast gain control in the LGN—a nonlinear receptive field property of LGN neurons whereby response gain during low‐contrast stimulation is enhanced relative to response gain during high‐contrast stimulation. In addition, these results support the view that network interactions beyond the retina play an essential role in transforming visual signals en route from retina to cortex.
Serum Albumin as a Prognostic Marker for Serious Non-AIDS Endpoints in the Strategic Timing of Antiretroviral Treatment (START) Study

Background Serum albumin may be used to stratify human immunodeficiency virus (HIV)-infected persons with high CD4 count according to their risk of serious non-AIDS endpoints. Methods Cox proportional hazards models were used to analyze the risk of serious non-AIDS events in the Strategic Timing of Antiretroviral Treatment (START) study (NCT00867048) with serum albumin as a fixed and time-updated predictor. Models with exclusion of events during initial follow-up years were built to assess the ability of serum albumin to predict beyond shorter periods of time. Secondarily, we considered hospitalizations and AIDS events. Results Among 4576 participants, 71 developed a serious non-AIDS event, 788 were hospitalized, and 63 experienced an AIDS event. After adjusting for a range of variables associated with hypoalbuminemia, higher baseline serum albumin (per 1 g/dL) was associated with a decreased risk of serious non-AIDS events (hazard ratio, 0.37 [95% confidence interval, .20-.71]; P = .002). Similar results were obtained in a time-updated model, after controlling for interleukin 6, and after excluding initial follow-up years. Serum albumin was independently associated with hospitalization but not with risk of AIDS. Conclusions A low serum albumin level is a predictor for short- and long-term serious non-AIDS events, and may be a useful marker of risk of noncommunicable diseases, particularly in resource-limited settings.
