Stability Analysis of P2P Worm Propagation Model with Dynamic Quarantine Defense (2011)

The propagation of P2P worm covers large area and causes great damage. A dynamic quarantine protocol is designed to quarantine the suspicious host in the P2P system. Then a mathematical model of PWPQ is proposed which considering the dynamic process of peer joining and leaving. The effect of dynamic quarantine on active P2P worm is analyzed. Through stability analysis for PWPQ model, a key argument of infection-free stable point which affect the P2P worm propagation, the basic reproduction number, is deduced. Simulation results show that the propagation model of P2P worms can reflect the P2P worm behaviors and the performance of our model is significantly better than other models, in terms of decreasing the number of infected hosts and reducing the worm propagation speed. When the basic reproduction number is less than 1, infection-free stable point is global stability and the P2P worm are eliminated. The PWPQ model gives some way to control P2P worm break out and gives guidelines to P2P worm detection and defense.

Impinging Circular Turbulent Jets (1974)

The normal impingement of turbulent circular jets on smooth walls is studied both experimentally and analytically. This type of flow can be divided into three distinct flow regions: the free-jet region; the impingement region; and the wall-jet region. The impingement region is the most important. It is shown that the impingement region occupies about 14% of the impingement height above the wall, whereas it extends about 22% of the impingement height radially. Semi-empirical methods to predict axail variations of velocity and static pressure are developed. Similarity of velocity and static pressure profiles is investigated and it is shown that these profiles are well described by the Gaussian error function. Variation of pertinent length scales are obtained empirically using dimensional analysis so that the time-averaged velocity and pressure fields in the impingement region can be predicted. A method to predict the wall shear stress in the impingement region is developed.

Poverty: An Ordinal Approach to Measurement (1976)

The primary aim of this paper is to propose a new measure of poverty, which should avoid some of the shortcomings of the measures currently in use. An axiomatic approach is used to derive the measure. The conception of welfare in the axiom set is ordinal. The information requirement for the new measure is quite limited, permitting practical use.

Resistin can promote steatosis in LO2 cells through the NF-kB signaling pathway, thereby contributing to the NAFLD pathogenic process.
Compositional variability in a cold‐water scleractinian, <i>Lophelia pertusa</i>: New insights into “vital effects” (2006)

We analyzed Sr/Ca and Mg/Ca ratios in the thecal wall of Lophelia pertusa , a cold‐water coral, using SIMS ion microprobe techniques. The wall grows by simultaneous upward extension and outward thickening. Compositional variability displays similar trends along the upward and outward growth axes. Sr/Ca and Mg/Ca ratios oscillate systematically and inversely. The sensitivity of Lophelia Sr/Ca ratios to the annual temperature cycle (−0.18 mmol · mol −1 /°C) is twice as strong as that exhibited by tropical reef corals, and four times as strong as the temperature dependence of Sr/Ca ratios of abiogenic aragonites precipitated experimentally from seawater. A comparison of the skeletal composition of Lophelia with results from precipitation calculations carried out using experimentally determined partition coefficients suggests that both temperature‐dependent element partitioning and seasonal changes in the mass fraction of aragonite precipitated from the calcifying fluid influence the composition of Lophelia skeleton. Results from calculations that combine these effects reproduce both the exaggerated amplitude of the Sr/Ca and Mg/Ca oscillations and the inverse relationship between Sr/Ca and Mg/Ca ratios.
<title>Content-based image retrieval via adaptive multifeature templates</title> (1999)

The use of image content analysis and image clustering techniques to organize an image database with a great variety of collections is investigated in this work. The objective is to bridge the gap between low-level features and their high level semantic meanings. We attempt this goal by using both coarse and fine classifications in image database organization. Image content analysis serves as the major tool in coarse classification. A set of typical image collections are studied by training their low-level feature vectors. Clusters of representative low-level features are further provided in form of semantic templates to provide fine-level classification clues for achieving a good query performance and serving as a supporting tool for browsing. With these multiple feature semantic templates, an interactive retrieval process can be conveniently implemented to incorporate user's feedback to achieve the desired query.
Trapping and recombination dynamics of low-temperature-grown InGaAs/InAlAs multiple quantum wells (1998)

We have observed a long-lived residual photoconductivity in low-temperature-grown (LT) InGaAs. These results have significant consequences for devices comprised of LT-InGaAs, other defect moderated materials, and standard-temperature-grown InGaAs. Our investigation utilizes time-resolved terahertz conductivity to quantify the trapping and recombination rates of LT Be-doped In0.53Ga0.47As/In0.52Al0.48As multiple quantum wells and bulk InGaAs. It is found that Be doping reduces the residual photoconductivity and increases the initial electron trapping rate. These results are in contrast to those observed via transient absorption studies, which suggest that these systems have returned to equilibrium after the initial transient. Furthermore, a 600 °C anneal increases both the trapping and recombination rate in all Be-doped samples.
Integrity Coasting Concept for General Aviation Users of the Ground Based Regional Augmentation System (2006)

It is now widely established that high performance navigation can be achieved by integrating GPS and low-cost inertial Micro-Electro-Mechanical Sensors (MEMS) measurements. However, the high noise and drift rates of these low-cost sensors, and their subsequent inability to coast for sufficient periods during GPS outages has hampered their widespread uptake in general aviation aircraft. The Ground Based Regional Augmentation System (GRAS) will bring high-integrity GPS navigation to General Aviation aircraft, however the potential exists that the GRAS signal could be lost for seconds or minutes at a critical time due to terrain masking or aircraft manoeuvres. A system is therefore needed which can coast through shortperiod GRAS outages, whilst taking advantage of the superior integrity provided by the GRAS Signal in Space (SiS) when it is available. This paper presents simulation results for a high performance navigation systemutilising low-cost MEMS inertial sensors and the GRAS. The system utilises the high accuracy and integrity of GPS navigation when the GRAS SiS is available to calibrate the inertial system parameters, and is then able to coast the navigation solution with high-integrity for short periods if the GRAS signal is not available.
Alignable lift-off transfer of device arrays via a single polymeric carrier membrane (2002)

We report epitaxial liftoff and direct bonding of GaAs/Al/sub x/Ga/sub 1-x/As heterostructure device arrays and continuous films, using a single, transparent polymer membrane to support the material during the etch of the sacrificial layer and to manipulate it into position for bonding in minutes. Au-Sn eutectic alloy bonding leads to a metallurgical bond in minutes. Absorption and current-voltage characteristics show that the material quality is not substantially degraded in the transfer process.

Exploiting Occluding Contours for Real-Time 3D Tracking: A Unified Approach (2007)

Model-based 3D object tracking is fast and robust using 3D edges. However, traditional edge-based approaches have difficulty handling occluding contours of curved surfaces, since they are not static model edges but change with the viewpoint. In this paper we propose a unified approach to edge-based tracking where 3D edges including occluding contours are utilized. This is achieved through an analysis of local surface differential geometry, which provides the foundation for incorporating occluding contours of curved surfaces into edge-based tracking. This approach uses a simple parametrization of both types of model edges within the same framework. The proposed method has been tested within the context of an existing edge-based tracking system. The system can track both types of model edges in a very fast and robust manner. Experimental results on both synthetic and real scenes are provided, which confirm that occluding contours improve real-time 3D tracking performance.
Differential expression of two neuronal intermediate-filament proteins, peripherin and the low-molecular-mass neurofilament protein (NF-L), during the development of the rat (1990)

The expression of peripherin, an intermediate filament protein, had been shown by biochemical methods to be localized in the neurons of the PNS. Using immunohistochemical methods, we analyzed this expression more extensively during the development of the rat and compared it with that of the low-molecular-mass neurofilament protein (NF-L), which is expressed in every neuron of the CNS and PNS. The immunoreactivity of NF-L is first apparent at the 25-somite stage (about 11 d) in the ventral horn of the spinal medulla and in the posterior part of the rhombencephalon. The immunoreactivity of peripherin appears subsequently, first colocalized with that of NF-L. Both immunoreactivities then spread out along rostral and caudal directions, but whereas the immunoreactivity of NF-L finally becomes noticeable in every part of the nervous system, that of peripherin remains localized to (1) the motoneurons of the ventral horn of the spinal medulla; (2) the autonomic ganglionic and preganglionic neurons; and (3) the sensory neurons. These results demonstrate that, in the neurons that originate from migrating neural crest cells, the immunoreactivities of peripherin and of NF-L become apparent only when they have reached their destination. The results also show that peripherin is expressed more widely than has been previously observed and that this protein occurs in neuronal populations from different lineages (neural tube, neural crest, placodes) with different functions (motoneurons, sensory and autonomic neurons). The common point of these neurons is that they all have axons lying, at least partly, at the outside of the axis constituted by the encephalon and the spinal medulla; this suggests that peripherin might play a role in the recognition of the axonal pathway through the intermediary of membrane proteins.
Electrochemical Reduction of Oxygen on Gold Nanoparticle-Electrodeposited Glassy Carbon Electrodes (2003)

The electrochemical reduction of oxygen on Au nanoparticle-electrodeposited glassy carbon electrodes (GCEs) has been performed in 0.1 M phosphate buffer solution (pH 7.2). Two well-separated electrochemical reduction peaks for on GCE were observed at about −750 and −2000 mV vs. Ag/AgCl/KCl (sat.) i.e., a peak separation of ca. 1250 mV. Those two peaks were attributed to the two-step four-electron reduction of to through A remarkable decrease of the separation of the two peaks (down to 550 mV) along with a significant positive shift of the two reduction peaks of to −350 and −9880 mV, respectively, were observed upon loading of a very minute amount of Au nanoparticles onto the GCE (typically g cm−2). Further positive potential shift of the two peaks along with a concurrent decrease of the peaks separation could be achieved by controlling the extent of Au loading on the GCE. Au-electrodeposited GCE with an equivalent Au film thickness of 10 nm showed almost the same behavior toward the reduction as the bulk Au electrode. These observations were interpreted in view of the increase of the effective (real) surface area of the Au film by the increase of its thickness, as indicated by scanning electron micrographs in addition to the characteristic cyclic voltammogram for Au nanoparticle-electrodeposited GCEs in -saturated 0.05 M © 2003 The Electrochemical Society.

Fully differential sigma-delta modulator structure for current-mode sensors (2016)

Many emerging systems, such as smart sensor interfaces for cyber-physical systems (CpS), require energy efficient analog-to-digital converters (ADCs). Low-order, continuous-time (CT), current-mode (CM) sigma-delta modulators (SDMs) can be an attractive solution due to their intrinsic ability to operate with ultra-low voltage signal swings, without requiring any voltage-mode amplifiers, whilst providing significant energy savings. A first-order, continuous-time, current-mode Sigma-Delta modulator (SDM) with high energy efficiency is proposed. The SDM, designed in a 65 nm CMOS technology.
Vibration characteristics of steel–concrete composite floor systems (2004)

Abstract Trends towards long‐span, lightweight floors in steel–concrete composite construction are resulting in structures possessing low natural frequencies, and potentially susceptible to vibration problems. The most common source of vibrations is caused by human activities on the floor, however, in some instances, mechanically induced vibrations from air conditioning plant, etc. may also be problematic. In this paper the serviceability assessment of floor vibration occasioned by walking activities is considered. Over 30 years ago concerns were raised regarding vibrations induced by walking on steel–concrete composite floors that satisfied traditional deflection criteria. In response to these concerns, design criteria based on a simple impulsive loading function from a person rising onto the balls of the feet, and suddenly dropping onto the heels has been used as a measure of floor acceptability. More recently, design procedures have been developed that more realistically consider the excitation of the floor from walking activities. In the first part of this paper a historical review of acceptability criteria for floor vibrations will be made. Following this, the current design methodologies for steel–concrete composite floors will be reviewed prior to the presentation of results from a series of in situ vibration tests on a wide variety of floor types. After comparing the test results with current guidance, design recommendations and suggestions for future research will be given.
MemorIES (2000)

Modern system design often requires multiple levels of simulation for design validation and performance debugging. However, while machines have gotten faster, and simulators have become more detailed, simulation speeds have not tracked machine speeds. As a result, it is difficult to simulate realistic problem sizes and hardware configurations for a target machine. Instead, researchers have focussed on developing scaling methodologies and running smaller problem sizes and configurations that attempt to represent the behavior of the real problem. Given the increasing size of problems today, it is unclear whether such an approach yields accurate results. Moreover, although commercial workloads are prevalent and important in today's marketplace, many simulation tools are unable to adequately profile such applications, let alone for realistic sizes.In this paper we present a hardware-based emulation tool that can be used to aid memory system designers. Our focus is on the memory system because the ever-widening gap between processor and memory speeds means that optimizing the memory subsystem is critical for performance. We present the design of the Memory I nstrumentation and E mulation S ystem (MemorIES). MemorIES is a programmable tool designed using FPGAs and SDRAMs. It plugs into an SMP bus to perform on-line emulation of several cache configurations, structures and protocols while the system is running real-life workloads in real-time, without any slowdown in application execution speed. We demonstrate its usefulness in several case studies, and find several important results. First, using traces to perform system evaluation can lead to incorrect results (off by 100% or more in some cases) if the trace size is not sufficiently large. Second, MemorIES is able to detect performance problems by profiling miss behavior over the entire course of a run, rather than relying on a small interval of time. Finally, we observe that previous studies of SPLASH2 applications using scaled application sizes can result in optimistic miss rates relative to real sizes on real machines, providing potentially misleading data when used for design evaluation.
Electrochemical Resource Recovery from Digestate to Prevent Ammonia Toxicity during Anaerobic Digestion (2012)

Ammonia inhibition during anaerobic digestion limits the substrate loading rate and endangers process stability. Furthermore, digestates are interesting feedstocks for nutrient recovery. In this lab-scale study, an electrochemical cell was used to investigate the NH(4)(+) flux from anode to cathode. Under optimal conditions with synthetic wastewater, an NH(4)(+) charge transfer efficiency of 96% and NH(4)(+) flux of 120 g N m(-2) d(-1) could be obtained at a concomitant electricity input of 5 kWh kg(-1) N removed. A more selective NH(4)(+) transfer could be established by maintaining a high concentration of other cations in the cathode compartment. Comparable NH(4)(+) fluxes could be obtained with digestate at an electrical power input of 13 kWh kg(-1) N removed and 41% current efficiency. The ammonium level in the digestate could be lowered from 2.1 to 0.8 - 1.2 g N L(-1). Interestingly, also potassium fluxes of up to 241 g K(+) m(-2) d(-1) could be obtained at 23% current efficiency. As the cathode can be operated at high pH without the need for chemical addition, stripping and absorption of dissolved ammonia could reach 100% efficiency. By valorization of the generated side products, this technology shows economic potential for practical application.
Seismic Design of Unbonded Post-Tensioned Precast Concrete Walls with Vertical Joint Connectors (2004)

An investigation of seismic design of precast concrete wall panels that have been connected along vertical joints with ductile connectors is presented. The panels are also connected to the foundations along horizontal joints by using unbonded post-tensioning steel. The objectives of this study are (1) to derive closed-form expressions for the base shear roof displacement capacities of unbonded post tensioned precast concrete walls and (2) to propose a design approach that relates wall capacities to code-specified design demands. Study results will also apply to walls with different numbers of panels and different panel sizes.
Lossless compression for archiving satellite telemetry data (2002)

Poincaré sphere representation of birefringent networks (1981)

The Poincareé sphere representation is used to analyze the operation of wavelength-dependent birefringent optical networks. A broadband input signal is spread on the sphere into a linear spectral density of states locus, which is in general further deformed on passage through subsequent birefringent elements. Unlike alternative mathematical procedures, this representation gives a clear visualization of the evolution of the state of polarization within an element, the dependence of that state on optical wavelength, and the requirements of a practical device design. Finally, it makes possible the synthesis of a new class of networks not previously considered.

Iron pentacarbonyl has been thermally decomposed in an organic liquid. M\"ossbauer spectroscopy and x-ray diffraction studies show that the sample contains small particles of a metallic glass. Annealing of the particles at 523 K results in crystallization of the particles into a mixture of \ensuremath{\alpha}-Fe and \ensuremath{\chi}-${\mathrm{Fe}}_{5}$${\mathrm{C}}_{2}$. The mechanism of glass formation is discussed.
