Understanding modern generator control (1989)

A simple discussion about generator control without bode plots and other sophisticated references necessary to equipment design is presented. Two kinds of control schemes used for most generator drives, droop control, and frequency control are discussed. Synchronous and induction generators, and their differences in control, are also discussed. The operation of generators both connected to and disconnected from the utility grid is also examined.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Potential and Advantages of Immunochemical Methods for Analysis of Foods (1986)

The technique of immunochemical analysis, including the principles involved, is described and the various types of assay are discussed. Application of these methods to the analysis of foods for residues of pesticides, contaminants, drug residues, and natural constituents is reviewed. Compared with conventional methods, immunoassays offer similar detection limits and greatly simplified sample preparation procedures.
Reliability Analysis of Non-Constant-Size Part Populations in Design for Remanufacture (2000)

Remanufacture offers significant economic and ecological advantages over other end-of-life options for appropriate products. The goal of this research is to estimate replacement requirements of parts in systems that are remanufactured. In our previous work, a novel repairable-system reliability model that allows system modifications was developed to describe a population of systems that are remanufactured. In this paper, the reliability model is modified to accommodate changes to the population size, while the population is in service, to better describe actual processes. The effects of two types of disturbances to population size, pulse and continuous, on the replacement rate behavior are studied. Analysis of actual industrial data is presented as an example of population replacement under continuous disturbance. This example confirms that a simulation using the reliability model described in this paper yields an estimate for replacement rate with acceptable error bound. [S1050-0472(00)00302-0]
Vestibular stimulation in mania: a case report. (2004)

Caloric vestibular stimulation is a common clinical procedure, routinely employed during testing of vestibulocochlear nerve function. The procedure involves stimulation of vestibular afferents by the application of cooled water to the tympanic membrane. Vestibular afferents are distributed widely to areas of the diencephalon and cortex, including areas believed to be involved in the regulation of mood. In accordance with these observations, imaging studies have shown widespread though largely contralateral hemispheric activation following the procedure.1

Caloric vestibular stimulation has been associated with a rapid but short lived improvement in stroke induced functional deficits,2 but the effect of the procedure on psychiatric symptomatology has not been reported. In the case described here, an improvement in manic symptoms was observed after caloric vestibular stimulation in a 29 year old woman with a 10 year history of bipolar affective disorder. The patient was admitted to an acute psychiatric ward with several weeks of increasingly elevated and irritable mood. Her symptoms fulfilled DSM-IV criteria for a manic episode. Resistance to therapeutic drug use and intolerance of side effects had limited effective management of her condition. Previous episodes of mania had often responded to ECT. At the time of admission her treatment regimen included olanzapine and carbimazole. Carbimazole had been started following the identification of abnormal thyroid function tests on routine testing.

Apoptotic signaling in bufalin‐ and cinobufagin‐treated androgen‐dependent and ‐independent human prostate cancer cells (2008)

Prostate cancer has its highest incidence in the USA and is becoming a major concern in Asian countries. Bufadienolides are extracts of toxic glands from toads and are used as anticancer agents, mainly on leukemia cells. In the present study, the antiproliferative and apoptotic mechanisms of bufalin and cinobufagin on prostate cancer cells were investigated. Proliferation of LNCaP, DU145, and PC3 cells was measured by 3-(4,5-dimethylthiazol-2-yle)-2,5-diphenyltetrazolium bromide assay and the doubling time (tD) was calculated. Bufalin and cinobufagin caused changes in the tD of three prostate cancer cell lines, which were more significant than that of human mesangial cells. In addition, bufadienolides induced prostate cancer cell apoptosis more significantly than that in breast epithelial cell lines. After treatment, the caspase-3 activity and protein expression of caspase-3, -8, and -9 were elevated. The expression of other apoptotic modulators, including mitochondrial Bax and cytosolic cytochrome c, were also increased. However, expression of p53 was only enhanced in LNCaP cells. Downregulation of p53 by antisense TP53 restored the cell viability suppressed by bufalienolides. Furthermore, the increased expression of Fas was more significant in DU145 and PC3 cells with mutant p53 than in LNCaP cells. Transfection of Fas small interfering RNA restored cell viability in the bufadienolide-treated cells. These results suggest that bufalin and cinobufagin suppress cell proliferation and cause apoptosis in prostate cancer cells via a sequence of apoptotic modulators, including Bax, cytochrome c, and caspases. The upstream mediators might be p53 and Fas in androgen-dependent LNCaP cells and Fas in androgen-independent DU145 and PC3 cells.
Structural and Electrochromic Properties of Tungsten and Molybdenum Trioxide Electrodes in Acidic Media (1990)

In situ x-ray diffraction (XRD) technique was employed to study unstable phases formed in sintered or anodically oxidized tungsten and molybdenum trioxide film electrodes under electrocoloration conditions in 0.5M H2SO4, in order to discuss their electrochromic characteristics on the basis of structural properties.The XRD patterns for tungsten trioxide film electrodes revealed that WO3 was transformed to hydrogen bronzes of WO3-x(OH)= (x = 0.1 and 0.5) in company with coloration while no structural change was observed in the anodic oxide film ofWO3 9 2H20.These findings supported that the electrocoloration proceeds according to the following processes: WO3 + xH + xe --* WO3-= (OH)= and WO3 9 2H20 + xH + xe ~ WO3-= (OH)=.2H20.For the sintered MoO~ film electrode, the crystal lattice was discontinuously expanded in the direction perpendicular to layers formed by MoO6 octahedra by insertion of proton to the layer under electrocoloration condition: MoO3 + xH + xe --~ MoO3-x (OH)=.The anodic oxide film formed on a Mo plate had been already colored blackblue, but it provided a different XRD pattern by cathodic polarization at -0.30V.
A COMPARISON OF THE GROWTH OF SELECTED MYCOBACTERIA IN H<scp>E</scp>L<scp>A</scp>, MONKEY KIDNEY, AND HUMAN AMNION CELLS IN TISSUE CULTURE (1958)

HeLa, monkey kidney, and human amnion cells in tissue cultures were compared as sites for the multiplication of strains of tubercle bacilli or original and reduced pathogenicity, and for several other species of mycobacteria capable of causing disease in humans. The arrangement of the pathogenic species inorder of their growth rates in HeLa cells was Mycobacterium fortuitum, Mycobacterium balnei, and the "yellow bacillus," followed closely by the tubercle bacillus. This order was also correct for these species in monkey kidney and human amnion cells, and is the same as that seen in bacteriological media. The arrangement of the strains of tubercle bacilli in order of their growth rates in all three types of cells was: H37Rv, then R1Rv, and lastly H37Ra, which multiplied about as slowly as BCG. An INH-resistant strain grew about as rapidly as H37Rv. Growth of the pathogenic species occurred at about the same rates in HeLa and monkey kidney cells, but was distinctly slower in human amnion cells, which are less active metabolically. Irradiation of the cells in doses up to 5000 r did not affect the subsequent growth of mycobacteria in them. Preliminary experiments with human leprosy bacilli indicate that they can be introduced into these cells in high numbers and that the bacilli then persist for the life of the cells.
Systolic-based 2D convolver for CNN in FPGA (2017)

Convolution is a primary mathematical operation used in many signal processing and analysis algorithms. High dependence of the complex systems on the correct operation of the convolver demands its continual improvements mostly related to the decrease of resource consumption. The paper proposes a model of 2D convolution massively used in the algorithms of image processing. The paper provides a detailed description of the model structure with focus on the implementation aspect. The model is particularly applied to the convolutional layer of Convolutional Neural Network, currently the most known image-based deep learning method. The key difference of the proposed model compared with other common implementations lies in the placement of line buffers. The correctness of the model design is validated through the simulation discussed at the end of paper.

Location-based services: advances and challenges (2004)

Since the US FCC issued an order in July 1996, requiring mobile operators to provide wireless emergency services to its customers, we have continuously witnessed an evolving breed of mobile positioning technologies. The mobile network operators, eager in seeking new and innovative ways to create differentiation and increase profits, envisaged potential new services with the mobile position information. One of the best ways to accomplish this is through the delivery of highly personalized services based on location. This has proved to be very illusive to researchers at large and up to date we are still waiting to see when the first commercial and large scale location based services (LBS) can be readily and economically available to customers. In this paper, we discuss the research issues involved in the development of LBS; describe recent work done in this area in our department at Hanover University. We finally outline some of the unmet research challenges, including highly accuracy mobile positioning techniques, roaming and billing issues, interoperability between operators (both national and international) and privacy or security problems associated with LBS.
Robust and fast numerical color separation for mathematical printer models (1998)

Halftone color printers can be mathematically modelled rather accurately using the Neugebauer equations or the Yule-Nielsen equations. However, the color separation which is the inverse of the printer model is not an easy task. For obtaining the printer driving parameters needed for a color the most appropriate methods comprises lookup tables, iterative inversion of the model, or an approximation. In order to avoid the memory requirement of a lookup table we investigate the suitability of the latter two approaches for the inversion of the Neugebauer and the Yule-Nielsen model in three and four color printing. The iterative approach is based on the Newton gradient scheme, the approximative approach consists of a refinement of the very simple method CMY = 1 - RGB. We compare both the results to the optimally achievable results (corresponding to a lookup table of infinite size) and demonstrate the only slightly inferior results.
Analysis and Optimization of Double-Jet Film-Cooling Holes (2013)

A parametric analysis and optimization of double-jet film-cooling holes was performed using three-dimensional Reynolds averaged Navier–Stokes equations with the shear stress transport turbulence model. The numerical results for film-cooling effectiveness were validated in comparison with experimental data. The lateral and streamwise distances between the centers of the holes, along with two lateral ejection angles, were chosen as the design variables. The effects of these four variables on the film-cooling effectiveness were evaluated. For optimization of double-jet film-cooling holes, film-cooling effectiveness was considered as the objective function. Latin hypercube sampling was used to determine the design points. A weighted average surrogate model was constructed using the objective function values calculated at the design points. Sequential quadratic programming was used to search for the optimal point from the constructed surrogate. The cooling performance of double-jet film-cooling holes was improved considerably by optimization in comparison with the reference geometry.
Three-Stage Multiconnection Networks Which Are Nonblocking in the Wide Sense (1979)

A multiconnection network deals with the connections of pairs {(X, Y)} where X is a subset of the input terminals and Y is a subset of the output terminals. We study the conditions under which a three-stage Clos network is nonblocking for such connections. We show that the number of middle switches needed for nonblocking depends on the routing strategy. Therefore the networks satisfying the conditions are networks nonblocking in the wide sense. We also derive formulas for computing the minimum numbers of crosspoints required by such networks.
Models of Minds and Memory Activities (2014)

Abstract This chapter argues that some contemporary reconstructive models of memory have retained a standard for “good” memory (as fidelity to an original impression) that derives from an outmoded archival model. From the perspective of the reconstructive view, which acknowledges that the needs and interests of selves and others influence memory, our recollections appear as distortions of the past. This chapter argues that when we dismiss the dubious norm of good remembering as reproductive fidelity, the reconstructivist theory no longer encourages skepticism. Campbell’s positive proposal for good remembering combines a need to get both the facts about the past and their significance for the present and future right. The phenomenon of nostalgia is used to illustrate one sort of failure to get the significance of past facts right.
Reductions in Wear Rate of Carbon Samples Sliding Against Wavy Copper Surfaces (1996)

Abstract Wear rates (μgm/s) versus rotor speed for carbon samples sliding against smooth and wavy copper rotors (250 μm thick copper sheets were attached to smooth and wavy steel and polycarbonate backings) were identical at some speeds, but at other speeds wear rates for the wavy rotors were almost half those of the smooth rotors. Slider vibrations (periodic, with period set by rotation) perpendicular to the sliding surface were measured and Fourier analyzed. Comparison of vibration spectral amplitudes to spectral amplitudes derived from surface profiles identified vibration modes dynamically enhanced by surface waviness on the wavy rotor. At speeds where wear rates on the wavy rotor were most reduced, amplitudes of certain modes in the vibration spectrum were most enhanced. For all these cases, the product of mode number times speed was nearly constant, suggesting resonance. Contact forces and contact voltage drop (due to a mA current flowing from slider to rotor) were measured and plotted versus time during all experiments. Friction coefficients rapidly varied between 0.1 and 0.4, but averaged 0.2. Traces of friction coefficient versus time for both wavy and smooth rotors were similar, even when wear rates plunged on the wavy rotor. There were no large jumps in the contact voltage drop data, suggesting that the slider never disconnected from any of the rotors. Photoelastic visualizations (Bryant and Lin, 1993) of slider-rotor interfaces revealed concentrated contact on the smooth rotors, but none on the wavy rotors. The absence (induced by vibration) of concentrated contact may have caused differences in wear rates. Appreciable reductions (up to 50 percent) in wear rate are possible by adding small surface waves to a rotor that induce micro-vibrations of the slider-spring-rotor contact system. The effect appears most pronounced at resonance.
Coordinated Boom Control System for Rough Terrain Forklifts (1991)

<div class="htmlview paragraph">Digital Electronics, Sensors, and Electro-hydraulic Control Valves have been combined to produce a system which automatically coordinates the variable reach boom on rough terrain forklifts to produce true Horizontal or Vertical Motion of the forks. The system results in fast and safe load placement and removal of forks from loads in high places with ease. Motion can be commanded by the operator to be horizontal or vertical. Boom Length sensors and Boom Angle sensors provide information to the micro-controller in order to control the motion of the boom which results in the desired horizontal or vertical motion regardless of slope of the terrain on which the vehicle is placed. Input of Engine Speed also ensures that the maximum flow commanded from the valves does not exceed flow available from the hydraulic pump resulting in smooth and fast coordinated boom motion at any engine speed. This paper describes the control system including the sensors, command joystick, and controller. The implementation of the control logic and trigonometry calculations will also be discussed.</div>
Neighbor discovery in wireless ad hoc networks based on group testing (2008)

Fast and efficient discovery of all neighboring nodes by a node new to a neighborhood is critical to the deployment of wireless ad hoc networks. Different than the conventional ALOHA-type random access discovery schemes, this paper assumes that all nodes in the neighborhood simultaneously send their unique on-off signatures known to the receive node. In particular, a transmitter does not transmit any energy during an “off” mini-slot in its signature sequence. The received signal can be viewed as the outcome of a sequence of tests over the mini-slots, where the outcome of a test is positive if there is energy at the corresponding mini-slot from at least one neighbor, and negative if none of the neighboring nodes transmits energy during the mini-slot. The neighbor discovery problem is thus equivalent to a classical group testing problem. Two practical and scalable detection algorithms are developed from the group testing viewpoint. Unlike some previous neighbor discovery schemes using coherent multiuser detection, which are difficult to implement due to lack of training, the proposed scheme requires only non-coherent energy detection. The proposed algorithms are shown to achieve faster and more reliable discovery than existing random access schemes.
Mesenchymal stromal cells and the innate immune response (2015)

Mesenchymal stromal cells (MSC) have been exploited for their immunomodulatory properties in the treatment of a number of immune-based disorders, including Graft versus Host Disease (GvHD) and type 1 diabetes. The mechanisms for inducing therapeutic effect still remain largely unknown however, with research focused on understanding how MSCs interact with individual immune cell subsets. Within this review we address what is known about the interactions of MSCs with cells of the innate immune system, how they respond to their microenvironment and how this relates to therapeutic effects we see both within in vivo animal models and in clinical trials.
Synthesis, Characterisation, and Electroluminescence Properties of <i>N</i>‐Coumarin Derivatives Containing Peripheral Triphenylamine (2014)

Abstract A series of N ‐coumarin derivatives, namely CTh n T and CTh n CT ( n = 1–2), containing triphenylamine or triphenylamine‐substituted carbazole as substituent were synthesised, and their structures were confirmed by MALDI‐TOF MS, and NMR and IR spectroscopy. Their optical, physical and electroluminescence properties as non‐doped solution‐processed light‐emitters for OLEDs were investigated. DSC, TGA, AFM and PL spectra revealed their good film‐forming properties, high thermal and morphological stability, and good photoluminescence characteristics. The double‐layer solution‐processed OLEDs (ITO/PEDOT:PSS/EML/BCP/LiF:Al) fabricated using CTh n T and CTh n CT as the emissive layer and BCP as the electron‐transporting and hole‐blocking layer, exhibited stable green to orange electroluminescence ( λ EL = 536–592 nm) with turn‐on voltages of 2.7–2.9 V and maximum luminance efficiencies up to 3.94 cd A –1 at 17.6 mA cm –2 (maximum power efficiency of 1.62 lm W –1 ).
High-linearity continuous-time filter in 5-V VLSI CMOS (1992)

High-linearity self-tuning continuous-time filters, fabricated in a standard 1.6- mu m 5-V CMOS process, are presented. Frequency control is achieved using switchable arrays of highly linear double-polysilicon capacitors in an active RC filter structure, resulting in tunable filters with very low signal distortion. One filter, a Tow-Thomas biquad, exhibits dynamic range and signal linearity of typically 91 dB. Another smaller implementation, a Sallen and Key filter, attains >or=76 dB. Cutoff frequency response is maintained to an accuracy of around +or-5%.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A standard disk for calibrating head-disk interference measuring equipment (1982)

A technique is described for producing standard disks for calibrating head-disk interference measuring equipment. The technique is more accurate than conventional methods, and yields disks with a much longer useful life. The method used is to sputter a group of small pads of tungsten onto a conventional oxide-coated rigid disk. The pads have a range of heights similar to the anticipated flying height of the head-disk combination under consideration. A glide-test head is then flown over the pads, and accurate thresholds are set according to the head output signal. It is shown how the thresholds can easily be set to an accuracy of ±1μ.
