A Driving Simulator Study on Adaptive Cruise Control Failure (2006)

Adaptive cruise control automatically adjusts vehicle speed and distance to a preceding vehicle, thus enhancing driver comfort and safety. Previous studies have shown that adaptive cruise control induces positive behavioral adaptation by drawing consistency in driving speed and headway-time regardless of driving styles. However, the studies have also shown that the drivers' reliance on the system induced negative adaptation including reduced lane keeping ability and reduced attention during driving. This study further investigated effect of negative behavioral adaptation to adaptive cruise control. Failure of adaptive cruise control was simulated using a full-scale driving simulator and driver behavior under the simulated failure was studied. Twenty drivers participated in the study to compare reaction time, distance between the cars, and eye movement. Three different driving scenarios were used: adaptive cruise control off, adaptive cruise control on and adaptive cruise control on followed by braking algorithm failure. Experiment results showed that the drivers took longer time to recognize and react to sudden speed reduction by the car ahead when driving with adaptive cruise control and even longer when adaptive cruise control failed. This indicates potential danger of negative behavioral adaptation to adaptive cruise control and requires prevention strategy such as education and public awareness
Photovoltaic effect on differential capacitance profiles of low-energy-BF2+-implanted silicon wafers (2003)

Using scanning capacitance microscopy (SCM), we have studied the photovoltaic effect on differential capacitance (dC/dV) signals of low-energy-BF2+-implanted silicon wafers. The surface photovoltage induced by the stray light of the atomic force microscope laser beam leads to distorted dC/dV profiles and hence perturbs the contrast of SCM images. Due to the photovoltaic effect on the junction region, the observed junction image also exhibits a narrower junction width. According to this study, the photovoltaic effect not only significantly affects the dC/dV signals but also deteriorates the accuracy of junction characterization, in particular for ultrashallow junctions and lower band-gap semiconductors.
Generation of finite difference formulas on arbitrarily spaced grids (1988)

Simple recursions are derived for calculating the weights in compact finite difference formulas for any order of derivative and to any order of accuracy on one-dimensional grids with arbitrary spacing. Tables are included for some special cases (of equispaced grids).
Template constructors for reusable object initialization (2013)

Reuse of and abstraction over object initialization logic is not properly supported in mainstream object-oriented languages. This may result in significant amount of boilerplate code and proliferation of constructors in subclasses. It also makes it impossible for mixins to extend the initialization interface of classes they are applied to. We propose template constructors, which employ template parameters and pattern matching of them against signatures of superclass constructors to enable a one-to-many binding of super-calls. We demonstrate how template constructors solve the aforementioned problems. We present a formalization of the concept, a Java-based implementation, and use cases which exercise its strengths.
Heat Transfer and Skin Friction Comparison of Dimpled Versus Protrusion Roughness (1996)

This paper presents results of skin friction and heat transfer measurements made on flat plates with closely-spaced, three-dimensional surface roughness elements (hemispherical dimples, hemispherical protrusions, and rectangular protrusions) in turbulent boundary-layer flow at velocities ranging from 18 to 40 m/s (roughness Reynold's nos. from 1500 to 4000). The roughness element densities for each plate were chosen using Simpson's sand-grain roughness correlation to study the effects of spacing on drag and heat transfer in the vicinity of the peak of the Simpson-Dvorak correlation curve. The data is presented in terms of the efficiency factor, n = (Str/Sts/(Cfr/Cfs), to provide a means of comparing the effects on skin friction and heat transfer collectively. Dimpled surfaces have the advantage of significantly increasing heat transfer at a lower penalty in increased drag compared to the protrusion roughness studied.
A Multi-Expert Signature Verification System for Bankcheck Processing (1997)

In this paper a multi-expert signature verification system is presented. The system has been specifically designed for applications in the field of bankcheck processing. For this purpose, it combines three different algorithms for signature verification. A wholistic approach is used in the first algorithm, a component-oriented approach is used in the second and third algorithms. The second algorithm is based on a structure-based procedure, the third algorithm uses a highly-adaptive neural network. The three algorithms are combined in the multi-expert system by a voting strategy.

LABOR MIGRATION TO THE CZECH REPUBLIC (2016)

The reasons for increasing interest in studying the links between migration and economic development are many, but the most important is undoubtedly the rising absolute number of immigrants in economically developed countries, increasing the amount of remittances sent for last 10-15 years and an aging population in developed countries. This article deals with labor migration in the Czech Republic, which greatly affects not only the labor market, but also the development of the country. Although the topic is very broad, which can hardly be described exhaustively due to limited space, the primary objective of the paper is to give a comprehensive view on the selected issue. The secondary objective of the paper is not only in analysis of the consequences that come along with the process of labor migration, but also in the preparation of forecasts which reflect the possible development of labor migration in the future. The paper analyzes the development of immigration to the Czech Republic from 1995 to 2013 and look at the impacts of labor migration on the labor market, which may occur for example in the form of risks of brain drain or demofigureic changes. The important part of the paper is a regression and correlation analysis which demonstrate the influence of the migration on GDP, wages, innovations and tax revenues.
A sliding window decorrelating receiver for multiuser DS-CDMA mobile radio networks (1996)

We detail the development of a near-far (NF) resistant sliding window decorrelating algorithm (SLWA) that overcomes the near-far problem (NFP) pertaining to the conventional linear correlation receiver (CLCR) and alleviates some of the limitations of the standard decorrelator. The SLWA architecture is extended to incorporate differentially coherent multipath (RAKE) diversity combining techniques and hence achieves simultaneous rejection of multiuser and multipath interference. This paper also presents a novel algorithm for updating the decorrelator coefficients using a fully parallel architecture. We present a mathematical model for the performance of a sliding window scheme, the main contribution of which is the analysis of finite sequence length multipath decorrelation under the practical limitation of incomplete RAKE combining. In addition to numerical results, we present results pertaining to capacity improvements achieved over the CLCR, derived from a simulation of a multiuser direct-sequence code-division multiple-access (DS-CDMA) mobile radio system.

<title>CO<formula><inf><roman>2</roman></inf></formula> Probe Laser With Rapid Wavelength Switching</title> (1977)

The wavelength switching probe laser as described in this paper is the key component in a "J-line scan" diagnostic system, that was developed during the past year at Rocketdyne. Typically, the J-line scan experiment consists of performing small signal gain measurements at a set of wavelengths, that correspond to different rotational transitions of the CO<sub>2</sub> molecule. From these gain measurements the rotational temperature of the CO2 (001) state may be computed, which in turn yields the amount of specific optical energy available in the active medium. The significance of being able to measure this quantity is substantial. A low power wavelength switching CO2 laser was designed and constructed, that allows scanning of up to 8 individual, selected wavelengths in rapid sequence. This probe laser incorporates several novel features. The wavelength scan of the probe laser is accomplished by a galvo controlled mirror, switching 8 prealigned gratings in sequence into the optical cavity of the probe laser. Accurate and rapid angular registration of the switch-mirror is achieved by using control loops. After the laser is switched to the next wavelength (in less then 10 milliseconds) the laser cavity length is then rapidly readjusted to lock cavity resonance to line center. An electronic control center was also developed, that provides fully automatic operation. This system is now fully operational. The present paper describes the system together with experience gained by using it on a medium scale Gas Dynamic Laser (GDL) device.
PsychoPy2: Experiments in behavior made easy (2019)

PsychoPy is an application for the creation of experiments in behavioral science (psychology, neuroscience, linguistics, etc.) with precise spatial control and timing of stimuli. It now provides a choice of interface; users can write scripts in Python if they choose, while those who prefer to construct experiments graphically can use the new Builder interface. Here we describe the features that have been added over the last 10 years of its development. The most notable addition has been that Builder interface, allowing users to create studies with minimal or no programming, while also allowing the insertion of Python code for maximal flexibility. We also present some of the other new features, including further stimulus options, asynchronous time-stamped hardware polling, and better support for open science and reproducibility. Tens of thousands of users now launch PsychoPy every month, and more than 90 people have contributed to the code. We discuss the current state of the project, as well as plans for the future.
OpenMP Teaching-Learning Based Optimization Algorithm over Multi-Core System (2015)

The problem with metaheuristics, including Teaching-Learning-Based Optimization (TLBO) is that, it increases in the number of dimensions (D) leads to increase in the search space which increases the amount of time required to find an optimal solution (delay in convergence). Nowadays, multi-core systems are getting cheaper and more common. To solve the above large dimensionality problem, implementation of TLBO on a multi-core system using OpenMP API's with C/C++ is proposed in this paper. The functionality of a multicore system is exploited using OpenMP which maximizes the CPU (Central Processing Unit) utilization, which was not considered till now. The experimental results are compared with a sequential implementation of Simple TLBO (STLBO) with Parallel implementation of STLBO i.e. OpenMP TLBO, on the basis of total run time for standard benchmark problems by studying the effect of parameters, viz. population size, number of cores, dimension size, and problems of differing complexities. Linear speedup is observed by proposed OpenMP TLBO implementation over STLBO.

ETTRINGITE AND OXYANION-SUBSTITUTED ETTRINGITES -- THEIR CHARACTERIZATION AND APPLICATIONS IN THE FIXATION OF HEAVY METALS: A SYNTHESIS OF THE LITERATURE (1998)

This report constitutes a synthesis of the literature relating to the formation, structure, analysis, and characterization of ettringite from a variety of sources including hydration of portland cement, calcium aluminates, expansive cements, rapid-set cements, hydration of fly ash and coal combustion by-products, and laboratory synthetic processes. The major focus of the review is on the formation and properties of oxyanion-substituted ettringites. Substituted ettringite structures generally contain oxyanions of amphoteric heavy metals such as chromium, boron, arsenic, and selenium. Such amphoteric metals, under the elevated pH conditions of hydrating portland cement, usually will form water-soluble oxyanion species such as chromate. However, it has been established that the ettringite structure can accommodate many such heavy metals oxyanions in place of the usual sulfate anion, and will thus exhibit a very high degree of insolubility at those pH values where heavy metal water-soluble oxyanions will readily be subjected to water leaching.
New ideas in FM radar (1990)

Design of Circularly Polarized Stacked Microstrip Antennas (2008)

A simple technique is developed to improve the axial ratio (AR) bandwidth and quality of circularly polarized stacked microstrip antennas (CPSMAs) using a new C-type single feed. The proposed antenna has been optimized and fabricated, and the computed results agree very well with measurements. The antenna has a 3 dB AR bandwidth of 11.6%, gain is more than 8.2 dBi and the impedance bandwidth for VSWR less than 2 is 29%. The proposed feed optimization technique is useful for rapid design of circular polarized stacked microstrip antennas.
Detection of Cryptosporidium oocysts in water: techniques for generating precise recovery data (1999)

When determining the recovery efficiency of a procedure for the detection of Cryptosporidium or the removal efficiency of a treatment process, it is necessary to accurately enumerate a 'seed dose'. Conventional techniques for this are highly variable and consequently, can result in misleading data. In this study, a flow cytometric method was developed for the production of suspensions of Cryptosporidium oocysts in which the number of organisms could be precisely determined. A Becton Dickinson FACScalibur flow cytometer was employed to produce oocyst suspensions containing 100 oocysts. Analysis of these suspensions resulted in a mean dose of 99.5 oocysts (S.D. = 1.1, %cv = 1.1). These results indicate that the use of such suspensions to seed test systems generates far more accurate data than is presently possible using conventional techniques. In addition, the use of immunomagnetic separation (IMS) for the isolation of oocysts from three different water matrices, after seeding with oocysts counted using flow cytometry, was investigated. The recovery efficiency of the IMS procedure was found to be high, with the percentage recovery of oocysts ranging from 82.3 to 86.3%, and the use of precise numbers of oocysts allowed accurate recovery efficiency data to be generated. A laser scanning instrument (ChemScan RDI) was employed for the rapid detection and enumeration of oocysts after capture using membrane filtration. This technique was found to be faster and easier to perform than conventional epifluorescence microscopy. These findings demonstrate that the ChemScan RDI system may be used as alternative procedure for the routine examination of IMS supernatant fluids for the presence of Cryptosporidium.
Research on the model and estimated strategy of SOC for drain battery of electric vehicle (2004)

The paper mainly described how to estimate the state of battery charge(SOC) on electric vehicle.Having deeply researched the main effective factors such as open-circuit voltage,self-resume effect,temperature,charge and discharge efficiency, circle life, the paper established a kind of new mathematics model and introduced a kind of combining estimated strategy. The combining estimated strategy choosed the optimal method in a few of means such as Open-circuit Voltage Estimation and Ah integral Estimation according to the state of battery. The combination of several estimated strategies avoided the disadvantages of single strategy and benefited to estimated precision.It was applied to electric vehicle successfully, and the estimated error of SOC was less than 4%.
Low-Density Rodent Communities in Eastern Virginia (2008)

Two communities of small mammals were live trapped every other week for 15 months in linear oilfield habitat bordered by forested swampland in eastern Virginia. All nine species of the rodent community were present, mostly in low numbers and often intermittently. All species were characterized by high transiency, with a minority of marked animals becoming resident. Despite high trappability, all but two species in these communities had extremely low densities, suggesting that most species could not sustain populations via in situ reproduction.
Finger Vein Recognition Based on a Personalized Best Bit Map (2012)

Finger vein patterns have recently been recognized as an effective biometric identifier. In this paper, we propose a finger vein recognition method based on a personalized best bit map (PBBM). Our method is rooted in a local binary pattern based method and then inclined to use the best bits only for matching. We first present the concept of PBBM and the generating algorithm. Then we propose the finger vein recognition framework, which consists of preprocessing, feature extraction, and matching. Finally, we design extensive experiments to evaluate the effectiveness of our proposal. Experimental results show that PBBM achieves not only better performance, but also high robustness and reliability. In addition, PBBM can be used as a general framework for binary pattern based recognition.

Physico-chemical and rheological properties of modified corn starches and its effect on noodle quality (2012)

In this study, three different modification methods (pregelatinization, acid-thinning and dextrinization) were used to produce the modified corn starches. Physicochemical and rheological properties of the native and modified corn starch were studied. In addition, the resultant modified corn starches were used at levels 5%, 10% and 15% to replace wheat flour in noodle processing. The crude protein and lipid contents of modified corn starches significantly decreased compared to native ones. Water and oil binding capacity of corn starch increased up to 1.49 and 2.35 g/g, respectively, after modifying by the pregelatinization method. Results also showed that the maximum solubility was given by dextrinized corn starch after heat treatment at 90 °C being 44.85%, which means about 5.9-fold increase in solubility as compared to native starch. However, acid-thinning modified corn starch showed a significant decreased effect on the syneresis of its gel in comparison to those of other modified starches and the native one. The maximum viscosity decreased in pregelatinized starch followed by acid-thinned starch in comparison to native corn starch. The same trend was found in the viscosity after holding at 95 °C for 15 min. The highest noodle weight and volume increases were recorded for noodles containing 5% and 10% of native corn starch followed by 10% of pregelatinized corn starch, as well as, the control. Replacing wheat flour with 5%, 10% and 15% of native or pregelatinized corn starch did not cause any negative effects on sensory attributes of noodles in comparison to the control sample. Finally, it could be concluded that the native and pregelatinized corn starch can be used up to 15% in noodle processing with high quality and acceptable sensory attributes.
