Real-Time Energy Management of a Stand-Alone Hybrid Wind-Microturbine Energy System Using Particle Swarm Optimization (2010)

Energy sustainability of hybrid energy systems is essentially a multiobjective, multiconstraint problem, where the energy system requires the capability to make rapid and robust decisions regarding the dispatch of electrical power produced by generation assets. This process of control for energy system components is known as energy management. In this paper, the application of particle swarm optimization (PSO), which is a biologically inspired direct search method, to find real-time optimal energy management solutions for a stand-alone hybrid wind-microturbine (MT) energy system, is presented. Results demonstrate that the proposed PSO-based energy management algorithm can solve an extensive solution space while incorporating many objectives such as: minimizing the cost of generated electricity, maximizing MT operational efficiency, and reducing environmental emissions. Actual wind and end-use load data were used for simulation studies and the well-established sequential quadratic programming optimization technique was used to validate the results obtained from PSO. Promising simulation results indicate the suitability of PSO for real-time energy management of hybrid energy systems.
<sup>7</sup>Li PGSE Diffusion Measurements on LiPPh<sub>2</sub>:  A Solvent Dependence of the Structure (2004)

The first application of 7Li pulsed-gradient spin-echo (PGSE) diffusion methods to structural lithium chemistry is reported. The data, which provide quantitative diffusion constants at 155 K, lead to a new method of estimating solvent viscosity at this temperature and clearly show a solvent dependence for the structure of LiPPh2. In THF, LiPPh2 exists as a mononuclear solvated species, whereas in Et2O, a dinuclear structure is found. D values for the model compound PHPh2 in THF have been measured.
Spatial kernel K-harmonic means clustering for multi-spectral image segmentation (2007)

The problem of image segmentation using intensity clustering approaches has been addressed in the literature. Grouping pixels of similar intensity to form clusters in an image have been tackled using a number of methods, such as the K-means (KM) algorithm. The K-harmonic means (KHM) was proposed to overcome the sensitivity of KM to centre initialisation. The use of a spatial kernel-based KHM (SKKHM) algorithm on the problem of image segmentation has been investigated. Instead of the original Euclidean intensity distance, a robust kernel-based KHM metric is employed to reduce the effect of outliers and noise. Spatial image information is also incorporated in the proposed clustering scheme, derived from Markov random field modelling. An extension of the proposed algorithm to multi-spectral imaging applications is also presented. Experimental results for both single-channel and multi-channel images demonstrate the robust performance of the proposed SKKHM algorithm.
Spacecraft Attitude Measurement Using Spatial Coherence of Laser or Star Light (1971)

A new method of measuring the attitude of spacecraft with respect to a reference beam of laser light or star light is described. The method uses the spatial coherence property of these beams and provides accuracies of ± 0.01 second of arc or greater. After giving a general description of the method, the feasibility of constructing such systems using presently available lasers and detectors is established. Finally, some aspects of the detection equipment are examined in detail.
C4 Polymorphism: Use of a Monoclonal Antibody toDistinguish C4A and C4B Locus Products (1984)

A monoclonal antibody reactive against C4B locus products was used in a passive immunoblotting technique to distinguish C4B from C4A electrophoretic variants. The technique is simple and has the advantage ofbeing able to distinguish clearly those C4B variants which may be either difficult to define by conventional hemolytic assay alone or which would normally be designated as C4B products on account of their lack of hemolytic function. Patterns detected by immunoblotting can be compared directly with patterns obtained by immunofixation with anti-C4 from the same gel.
Hormone Replacement Therapy (1996)

More than 40 million women in the United States are now going through or are past menopause. Another 3.5 million or more will reach midlife in the next decade. As their life expectancy increases (mean life expectancy of women is now approximately 84 years), so does the need for therapeutic regimens related to reproductive function and aging in woman. Few medical treatments available to menopausal and postmenopausal women have as much potential benefit as well as possible health risks as hormone replacement therapy (HRT). Despite the increasing amount of scientific data available regarding the benefits of HRT, a degree of uncertainty still remains, both in the minds of some women, and with some health professionals, regarding the risks associated with long-term therapy. Even though the literature is voluminous, contradictory, and unclear, health providers must be able to keep abreast of current knowledge about the benefits, risks, and unknowns of these drugs. The purpose of this article is to provide a review and an update on the types of hormones available for HRT, their pharmacology and pharmacokinetics, and their risks, benefits, and contraindications. Newer products, specially compounded formulas, new regimens, and new modes of delivery that offer women alternatives and allow care to be individualized are described. In addition, some of the ongoing management dilemmas that practitioners face with the woman who chooses HRT are presented with practical solutions and suggestions.
Precision Spindle Metrology (2008)

The demand for advancement of the accuracy and productivity in production systems continues to increase. At the heart of these production demands are high-speed machine tools and multi-tasking machine tools; at the heart of these machine tools are their spindles. These spindles continue to increase in variety, maximum speed, and number of spindles per machine; therefore, standardization and accurate and efficient tests of spindle performance have been demanded by the pursuit of productivity. Especially needful are tests at full operating speed rather than simple static measurements.With these points as background, the ISO standard on “Geometric accuracy of axes of rotation (ISO230-7)” was released in 2006 as the universal performance test method for machine tool spindles to help comply with these ever increasing demands.Given these current demands, the publication of Precision Spindle Metrology is very significant. This book will be very helpful to the study of the necessary concepts and techniques in the measurement and analysis of spindle performance. Because the contents of the book are detailed and practical, it will help establish a complete system for the metrology of precision spindles. The book addresses all of the important considerations for spindle metrology:The spindle error motion is systematically classified based on the mode of error motion, behavior in the frequency domain, and the sensitive direction for machining accuracy. The required measurement and analysis techniques for accurate assessment of spindle performance are clearly explained.All elements required for establishing a metrology system for precision spindles are described in detail:fundamental knowledge of the required instruments: Artifact, sensor, fixture, and data acquisition system;environmental effects to be considered for reliable results from performance tests;fundamental knowledge of data acquisition and processing the acquired data;filtering techniques in data acquisition and analysis;methods for separation of the artifact error from the acquired data and their features.Case studies of metrology systems for spindles of typical machine tools and bearings (a major element of machine tools) are described with measurement data.Ample bibliography is attached at the end of chapter to study more in detail.This book gives deep understanding of the metrology of precision spindles. Marsh describes the concepts, methods, and their meaning for measurement and analysis of spindle performance in detail with abundant figures and actual values as examples. Moreover, detailed description is given to critical factors worthy of our attention in the measurement process and how we should analyze the acquired data. This makes the book very practical.This book will be helpful for engineers and researchers in the precision machine industry as well as students trying for the first time to carry out performance tests of the rotational element with high accuracy such as machine tool spindles. In addition, this book will also help the readers very much who want to carry out spindle performance tests according to ISO230-7.
LONGITUDINAL SLOPE CHARACTERISTICS OF RIVERS OF THE MIDCONTINENT AND THE ATLANTIC EAST GULF SLOPES (1969)

Abstract This study of longitudinal stream profiles of rivers of the Midcontinent (rivers tributary to the Mississippi) and Atlantic and East Gulf Slopes has revealed five types of longitudinal profiles: (1) Overall concave-upward profiles with or without long constant slope segments; (2) convex upward, for example, the Missouri River has a profile that has a constant slope for its lower 560 miles and then is convex upward with constant slope segments to a point beyond the Yellowstone River junction; (3) concave-upward irregular, ungraded, low-gradient profiles (Ohio and Tennessee Rivers); (4) irregular unsegmented and steep profiles, such as shown by the Delaware and Savannah-Tugaloo Rivers; and (5) irregular ungraded, steep-gradient profiles that are concave-upward in the upstream reaches and downstream convex-upward, for example, on most of the Atlantic Slope and East Gulf Slope Rivers above the Fall Line. Constant slope profiles occur where the last type of rivers flow across relatively weak Coastal Plain sediments and also inland on the Coosa and Oostanaula-Conasauga Rivers. The profile characteristics of the Atlantic and East Gulf streams lend support to the hypothesis of multiple erosion cycles in the Appalachians.

α-Tocopherol concentration and stereoisomer composition in plasma and milk from dairy cows fed natural or synthetic vitamin E around calving (2006)

The aim of this study was to compare the effects of supplementing dairy cows with 1000 IU/day of all-rac-alpha-tocopheryl acetate (SynAc), RRR-alpha-tocopheryl acetate (NatAc), or RRR-alpha-tocopherol (NatAlc), from approximately 3 weeks before estimated calving until 2 weeks after calving, on the concentration of alpha-tocopherol and its stereoisomers (RRR-, RSS-, RRS-, RSR- and the four 2S-forms of alpha-tocopherol) in blood and milk. An unsupplemented group was included as control. Blood samples were collected at 3, 2 and 1 weeks before estimated calving, at calving, and 3, 7 and 14 days after calving, while milk samples were taken twice within 24 h after calving and at 7 and 14 days in milk. Overall, time and treatment had significant effects on plasma alpha-tocopherol with higher concentrations in NatAc than in the other groups. In addition, SynAc had higher concentrations than Control, and NatAlc tended to be higher than Control. The lowest plasma concentrations were observed at calving and 3 days after calving. Independent of treatment, the concentration was higher in colostrum than in milk day 7 and 14 after calving. Analyses of the stereoisomer distribution in plasma and milk showed that, irrespective of dietary treatment, RRR-alpha-tocopherol was the most predominant form, constituting more than 86%, whereas the remaining part of alpha-tocopherol was made up by the three synthetic 2R isomers, while the 2S isomers only contributed less than 1% of the total alpha-tocopherol. In control cows and cows supplemented with natural vitamin E, the proportion of RRR-alpha-tocopherol in plasma and milk constituted more than 98% of the total alpha-tocopherol. In conclusion, the results indicate that daily oral supplementation of dairy cows with RRR-alpha-tocopheryl acetate gives the highest blood concentrations of alpha-tocopherol in the periparturient period. Analyses of the distribution of the individual stereoisomers of alpha-tocopherol further indicate that the bioavailability of RRR-alpha-tocopherol relative to synthetic stereoisomers in cattle is considerably higher than officially accepted until now.
Does Depreciation Make Sense? (1956)

THE IMPORTANCE OF FUNDAMENTAL rethinking of depreciation accounting is vital to the railroad financing of the next ten years. President Symes of the Pennsylvania Railroad has stated that our railroads would require $20 billion for new equipment and new facilities over the next ten years. That is an enormous amount for private industry. How much of the $20 billion will be generated from customary depreciation accruals? Depreciation of way and equipment in 1955 amounted to $535,000,000. The annual amount will increase as new equipment and depreciable facilities raise the base. Perhaps we may assume a total of $7.5 billion of the $20 billion will come in this rather painless manner. Examination of two points will be illuminating: (1) The creation of added debt by our industry should not be discouraged as a matter of course. It should be positively encouraged, if it will result, as I am sure it can in the majority of railroad situations, in so adding to earnings available for fixed charges as to improve the over-all credit picture. Certainly the borrowing for diesels did just that. (2) The amount of net earnings that can be plowed back in the next ten years consistently with good investor relations is probably about 50%. Assuming earnings for the next ten years at the level of the years 1951-55, inclusive, we might count on plowing back about $4 billion. This covers by depreciation and plowback $11.5 billion of the $20 billion, leaving $8.5 billion to be obtained outside the railroads.
Expert system for network configuration and diagnosis (2002)

An expert system to configure and diagnose a TNET multidrop network is presented. The TNET expert system (TEXSYS) was developed to ease the burden of device configuration and problem determination. It is written in the C programming language on an IBM personal computer, PS/2 model 80. A prototype development subsystem gives the user a tool to build and design the network. A configuration subsystem automatically initializes each node to the desired communication parameters. A diagnostic subsystem performs instream diagnostics while interacting with a running application program. All of these subsystems are merged together to form a single working expert system that is ready to lend assistance to the user. An introduction to TNET, the equipment used, the configuration, and the expert system implementation are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Immersion tin: Its chemistry, metallurgy, and application in electronic packaging technology (1984)

The surfaces in copper-plated through-holes in printed circuit boards for complex electronic packaging can be made solderable by immersion deposition of tin. The properties of the prepared surfaces vary from those of “white immersion tin,” which is easily wetted by molten tin solder, to those of “gray immersion tin,” which is nearly nonwettable. The wettability affects the electrical contact between the printed circuit board and the modules on it. In this paper, the rate law for tin deposition in the tin immersion plating bath is studied. Certain effects of chemical composition of the plating bath upon the character of the tin layer are investigated and the effects of thermal annealing of the plated surface upon the composition of the tin layer are determined. The differences in composition of white and gray immersion tin surface coatings are revealed by X-ray diffraction Rutherford backscattering spectroscopy and Auger electron spectroscopy. Solderability tests on Sn, Cu, Cu <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> Sn, and immersion tin surfaces are included.

Application of Monolithic CMOS Switched-Capacitor Filters and Amplifiers for Signal Processing (1980)

A custom monolithic CMOS array was designed and integrated for use in meeting the analog conditioning requirements for microsignal processors. These processors are used in "smart" sensors for the purposes of detection and classification. Constrained by very low power dissipation requirements, this array provides a variety of bandpass and low-pass filter functions and programmable CMOS operational amplifiers for AGC amplification for signals in the audio region. Specifically, the custom chip contains 12 poles based on switchedcapacitor techniques partitioned into a 6-pole low-pass filter ladder configuration, and three 2-pole bandpass and low-pass state variable filter configurations. The amplifiers were used in conjunction with an associated microprocessor for software-controlled AGC. A mask change can provide for different capacitor ratios, and hence, frequency responses. Also, the switch clock rates can be used to vary the filter characteristics. Operating from a single +5 V supply, this standard process chip dissipates about 2 mW, and meets all predicted performance characteristics.
Enhanced thermal stability and microhardness in Zr–Ti–Cu–Ni–Be bulk amorphous alloy by carbon addition (1997)

The effects of carbon addition on thermal stability and hardness of Zr41Ti14Cu12.5Ni10Be22.5 bulk amorphous alloy were investigated. It is found that a small amount of carbon addition further extends the supercooled liquid range and enhances the thermal stability and strength of the alloy. More carbon addition results in the formation of a crystalline and amorphous mixture accompanied by a pronounced increase in microhardness. The effects of the carbon addition on the amorphous alloy are discussed from the structural point of view.
Maxillary alveolar ridge augmentation using distraction osteogenesis: a literature review and case report. (2005)

The restoration of the edentulous atrophic anterior maxillary ridge has proved difficult. The absence of both gingival and bony alveolar tissue contributes to these problems. Numerous techniques to address these issues have been described. We report a case of a patient who sustained multiple facial injuries as a consequence of an accident, including the loss of the maxillary incisor teeth and associated alveolus. This patient underwent fixed implant supported prosthetic rehabilitation, following the use of distraction osteogenesis in the reconstruction of the edentulous atrophic anterior maxillary ridge.
ROLE OF ENDOGENOUS CATECHOLAMINES IN THE ANTI‐INFLAMMATORY ACTIVITY OF α‐ADRENOCEPTOR BLOCKING AGENTS (1974)

1 Drugs which release or modify the response to catecholamines were examined for their effect on the permeability of the mouse peritoneal vascular bed to circulating plasma albumin, labelled with Evans blue.2 Phenoxybenzamine, phentolamine, piperoxane, yohimbine or cocaine reduced the extravasation of Evans blue into the peritoneum, an effect which was antagonized by beta-adrenoceptor blocking drugs. The inhibitory effect of desipramine on the extravasation of Evans blue was less completely antagonized by beta-adrenoceptor blockade.3 Inhibition of catecholamine biosynthesis, ganglion blockade or adrenergic neurone blockade antagonized the reduction in dye extravasation by alpha-adrenoceptor blocking agents and cocaine, but had no significant effect on the response to desipramine. The inhibitory effects of alpha-adrenoceptor blocking agents on dye extravasation were not prevented by bilateral adrenalectomy.4 Mice subjected to the procedure for estimation of vascular permeability excreted increased amounts of adrenaline and noradrenaline. Pretreatment with phenoxybenzamine, piperoxane or cocaine further increased catecholamine excretion, but desipramine caused only a small increase in catecholamine excretion which did not correlate with its effect on dye extravasation.5 It is suggested that phenoxybenzamine, phentolamine, piperoxane and cocaine reduce vascular permeability in the mouse peritoneum by releasing and/or potentiating the effects of endogenous catecholamines on beta-adrenoceptors. Endogenous catecholamines do not appear to be involved in the anti-inflammatory activity of desipramine.
On Laves' Graph Of Girth Ten (1955)

1. Introduction. This note shows how a certain infinite graph of degree three, discovered by Laves in connection with crystal structure, can be inscribed (in sixteen ways, all alike) in an infinite regular skew polyhedron which has square faces, six at each vertex. One-eighth of the vertices of the polyhedron are vertices of the graph, and the three edges of the graph that meet at such a vertex are diagonals of alternate squares. Thus either diagonal of any face of the polyhedron can serve as an edge, and the whole graph can then be completed in a unique manner.
Effects of Hyaluronate, Strontium and Prolonged Incubation on Different Sperm Parameters (1993)

The aim of this study was to evaluate the effect of hyaluronate and strontium with short and prolonged incubation periods on different sperm parameters. For sperm intended for in vitro fertilization good progressive motility, a high percentage of normal form, a suitable linear velocity and a low acrosome-reacted proportion of sperm are required. The semen washing procedure in the self-migration method with medium containing hyaluronate Ca2+ after 3 h of incubation complies better with these criteria.
Improving schizophrenic in‐patients' Wisconsin card‐sorting performance (1996)

The effectiveness of a training procedure to improve schizophrenic patients' Wisconsin Card Sorting Test performance was investigated. In the absence of the monetary incentive often employed, 10 schizophrenic in-patients' performance improved with training. This study provides further evidence that the cognitive deficiency associated with the frontal lobe, implied by schizophrenic patients' typically poor Wisconsin Card-Sorting Test performance, is remediable.
