International winding wire standards-progress towards harmonization (2003)

It is noted that increases in international trade in electronic/electrical products have focused attention upon a greater need for having a common language for addressing and describing the various common winding wires produced throughout the world. The author shows the current status of the language, in the form of standards sanctioned by the International Electrotechnical Commission (IEC). The most recent publications for magnet wire specifications, test methods, packaging requirements, and basic dimensions are reviewed. Several common denominators between IEC and National Electrical Manufacturers Association (NEMA) standards are discussed. A table shows some of the key elements to be used in equating wire specifications listed by the IEC to other national wire standards. Both the direction of present efforts and possible future needs for winding wire (magnet wire) harmonization are included.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Abrasive drill for resilient materials (1981)

Resilient materials normally present problem in obtaining accurate and uniform hole size and position. Tool is fabricated from stiff metal rod such as tungsten or carbon steel that has diameter slightly smaller than required hole. Piercing/centering point is ground on one end of rod. Rod is then plasma-sprayed (flame-sprayed) with suitable hard abrasive coating. High-speed, slow-feed operation of tool is necessary for accurate holes, and this can be done with drill press, hard drill, or similar machines.

Nonconvex Splitting for Regularized Low-Rank + Sparse Decomposition (2012)

We develop new nonconvex approaches for matrix optimization problems involving sparsity. The heart of the methods is a new, nonconvex penalty function that is designed for efficient minimization by means of a generalized shrinkage operation. We apply this approach to the decomposition of video into low rank and sparse components, which is able to separate moving objects from the stationary background better than in the convex case. In the case of noisy data, we add a nonconvex regularization, and apply a splitting approach to decompose the optimization problem into simple, parallelizable components. The nonconvex regularization ameliorates contrast loss, thereby allowing stronger denoising without losing more signal to the residual.
Process rather than pattern: finding pine needles in the coevolutionary haystack (2008)

The geographic mosaic theory is fast becoming a unifying framework for coevolutionary studies. A recent experimental study of interactions between pines and mycorrhizal fungi in BMC Biology is the first to rigorously test geographical selection mosaics, one of the cornerstones of the theory.
Fault detection and isolation on a PWM inverter by knowledge-based model (1998)

This paper presents an approach based on knowledge models to detect and isolate faults in a pulsewidth modulation inverter supplying a synchronous machine. These faults do not affect the system protection. A diagnosis system which uses only the input variables of the drive is presented. It is based on the analysis of the current-vector trajectory and of the instantaneous frequency in faulty mode. These two methods have been successfully applied to an experimental system.
Computer Controlled Videodisc/Videoplayer System (1980)

Data-Design Laboratories System 110 is stand-alone, interactive-video training device. Experience in developing material for both the videodisc and videotape versions of System 110 has strongly indicated that each medium has independent interactive applications. Videotape is an excellent means of pacing and reinforcing instruction in “motion picture” presentations. Videodisc is very effective when the video segments are less interdependent or when still frames are to be employed.
Bacillus velezensis is a later heterotypic synonym of Bacillus amyloliquefaciens (2008)

Strain BCRC 14193, isolated from soil, shared more than 99 % 16S rRNA gene sequence similarity with Bacillus amyloliquefaciens BCRC 11601(T) and Bacillus velezensis BCRC 17467(T). This strain was previously identified as B. amyloliquefaciens, based on DNA-DNA hybridization, but its DNA relatedness value with B. velezensis BCRC 17467(T) was 89 %. To investigate the relatedness of strain BCRC 14193, B. amyloliquefaciens and B. velezensis, the partial sequence of the gene encoding the subunit B protein of DNA gyrase (gyrB) was determined. B. velezensis BCRC 17467(T) shared high gyrB gene sequence similarity with B. amyloliquefaciens BCRC 14193 (98.4 %) and all of the B. amyloliquefaciens strains available (95.5-95.6 %). DNA-DNA hybridization experiments revealed high relatedness values between B. velezensis BCRC 17467(T) and B. amyloliquefaciens BCRC 11601(T) (74 %) and the B. amyloliquefaciens reference strains (74-89 %). Based on these data and the lack of phenotypic distinctive characteristics, we propose Bacillus velezensis as a later heterotypic synonym of Bacillus amyloliquefaciens.
Regulation of the Histidine Utilization (Hut) System in Bacteria (2012)

The ability to degrade the amino acid histidine to ammonia, glutamate, and a one-carbon compound (formate or formamide) is a property that is widely distributed among bacteria. The four or five enzymatic steps of the pathway are highly conserved, and the chemistry of the reactions displays several unusual features, including the rearrangement of a portion of the histidase polypeptide chain to yield an unusual imidazole structure at the active site and the use of a tightly bound NAD molecule as an electrophile rather than a redox-active element in urocanase. Given the importance of this amino acid, it is not surprising that the degradation of histidine is tightly regulated. The study of that regulation led to three central paradigms in bacterial regulation: catabolite repression by glucose and other carbon sources, nitrogen regulation and two-component regulators in general, and autoregulation of bacterial regulators. This review focuses on three groups of organisms for which studies are most complete: the enteric bacteria, for which the regulation is best understood; the pseudomonads, for which the chemistry is best characterized; and Bacillus subtilis, for which the regulatory mechanisms are very different from those of the Gram-negative bacteria. The Hut pathway is fundamentally a catabolic pathway that allows cells to use histidine as a source of carbon, energy, and nitrogen, but other roles for the pathway are also considered briefly here.

Offset cylindrical reflector antenna fed by a parallel-plate luneburg lens for automotive radar applications in millimeter-wave (2003)

Using a single offset cylindrical parabolic reflector and a parallel-plate Luneburg lens, a novel high-gain and high-efficiency antenna is developed for automotive radar at mm-wave frequencies. Particularly, a pair of small corrugated extensions is added to the lens for a cylindrical wave. Thus, by feeding a cylindrical wave to the reflector, especially the performance in elevation is enhanced, keeping the complete antenna compact. For verification, a prototype antenna for an adaptive cruise control radar at 76.5 GHz is designed and measured. The theoretical results are verified with good agreement.
A Study on Intelligent User-Centric Logistics Service Model Using Ontology (2014)

Much research has been undergone in the smart logistics environment for the prompt delivery of the product in the right place at the right time. Most of the services were based on time management, routing technique, and location based services. The services in the recent logistics environment aim for situation based logistics service centered around the user by utilizing various information technologies such as mobile devices, computer systems, and GPS. This paper proposes a smart logistics service model for providing user-centric intelligent logistics service by utilizing smartphones in a smart environment. We also develop an OWL based ontology model for the smart logistics for the better understanding among the context information. In addition to basic delivery information, the proposed service model makes use of the location and situation information of the delivery vehicle and user, to draw the route information according to the user’s requirement. With the increase of internet usage, the real-time situations are received which helps to create a more reliable relationship, owing to the Internet of Things. Through this service model, it is possible to engage in the development of various IT and logistics convergence services based on situation information between the deliverer and user which occurs in real time.

Chip test optimization using defect clustering information (2003)

The authors recently proposed an adaptive wafer-probe testing approach which used defect clustering information on the wafer to optimize die test cost and quality. They show that this information can also be captured and used to optimize the testing of packaged chips. The effectiveness of the proposed approach is analyzed for negative binomial defect statistics. The results show that a three- to five-fold improvement in defect levels can be easily obtained for the same test costs. It is also possible to separate out chips with defect levels over an order of magnitude better than the best possible method without using defect clustering information.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Magnetic and structural properties of permalloy-tantalum multilayer thin films (1991)

This work describes a detailed investigation into the magnetic and structural properties of permalloy-tantalum multilayered thin films produced by vacuum evaporation. Their microstructure was investigated using high-resolution TEM and the magnetic properties were measured with vibrating-sample and vibrating-reed magnetometers. The results show a reduction in coercivity for the multilayer films which is independent of the number of layers but depends strongly on the magnetic layer thickness. The tantalum layer is shown to be continuous and microcrystalline down to 25-Å thickness, but the interface between the layers is irregular and may give rise to additional magnetostatic coupling as the tantalum layer thickness is reduced.
La Biblioteca del Ministerio de Trabajo y Seguridad Social: Pasado y presente (1993)

La nueva Biblioteca del Ministerio da Trabajo y Seguridad Social surge de un proyecto de modernizacion basado en su informatizacion, la fusion de diversas bibliotecas y su instalacion en un nuevo edificio. Desde estas bases, se pretende recuperar algo de su historica proyeccion cultural y cientifica hacia el exterior compaginando su condicion de biblioteca al servicie de un departamento ministerial con su voluntad de apoyo a la investigacion y al conocimiento de las materias sociolaborales. Con el fin de posibilitar esta doble funcion, se han llevado a cabo una serie de acciones organizativas que deben redundar en mayores facilidades para el acceso y la consulta de sus fondos y sentar las bases necesarias para cooperan con otras bibliotecas nacionales y extranjeras. Entre estas iniciativas destaca la organizacion formal de un servicio de referencia a informacion bibliografica y una nueva articulacion de las colecciones en varias secciones.
Anti-inflammatory Effect of Spilanthol from Spilanthes acmella on Murine Macrophage by Down-Regulating LPS-Induced Inflammatory Mediators (2008)

Spilanthes acmella (Paracress), a common spice, has been administered as a traditional folk medicine for years to cure toothaches, stammering, and stomatitis. Previous studies have demonstrated its diuretic, antibacterial, and anti-inflammatory activities. However, the active compounds contributing to the anti-inflammatory effect have seldom been addressed. This study isolates the active compound, spilanthol, by a bioactivity-guided approach and indicates significant anti-inflammatory activity on lipopolysaccharide-activated murine macrophage model, RAW 264.7. The anti-inflammatory mechanism of paracress is also investigated. Extracts of S. acmella are obtained by extraction with 85% ethanol, followed by liquid partition against hexane, chloroform, ethyl acetate, and butanol. The ethyl acetate extract exhibits a stronger free radical scavenging capacity than other fractions do, as determined by DPPH and ABTS radical scavenging assays. The chloroform extract significantly inhibits nitric oxide production ( p < 0.01) and is selected for further fractionation to yield the active compound, spilanthol. The diminished levels of LPS-induced inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) mRNA and protein expression support the postulation that spilanthol inhibits proinflammatory mediator production at the transcriptional and translational levels. Additionally, the LPS-stimulated IL-1beta, IL-6, and TNF-alpha productions are dose-dependently reduced by spilanthol. The LPS-induced phosphorylation of cytoplasmic inhibitor-kappaB and the nuclear NF-kappaB DNA binding activity are both restrained by spilanthol. Results of this study suggest that spilanthol, isolated from S. acmella, attenuates the LPS-induced inflammatory responses in murine RAW 264.7 macrophages partly due to the inactivation of NF-kappaB, which negatively regulates the production of proinflammatory mediators.
The effect of counterfactual priming on women's decisions regarding mammography screening (2008)

The counterfactual priming effect occurs when "what if" and "if only" thoughts about one event broadens ones mind-set to consider a more diverse range of evidence and possibilities in a different decision making or problem solving context. This study examined this effect as applied to mammography screening decisions.
Acetamido Sugar Biosynthesis in the Euryarchaea (2008)

Archaea and eukaryotes share a dolichol phosphate-dependent system for protein N-glycosylation. In both domains, the acetamido sugar N-acetylglucosamine (GlcNAc) forms part of the core oligosaccharide. However, the archaeal Methanococcales produce GlcNAc using the bacterial biosynthetic pathway. Key enzymes in this pathway belong to large families of proteins with diverse functions; therefore, the archaeal enzymes could not be identified solely using comparative sequence analysis. Genes encoding acetamido sugar-biosynthetic proteins were identified in Methanococcus maripaludis using phylogenetic and gene cluster analyses. Proteins expressed in Escherichia coli were purified and assayed for the predicted activities. The MMP1680 protein encodes a universally conserved glucosamine-6-phosphate synthase. The MMP1077 phosphomutase converted alpha-D-glucosamine-6-phosphate to alpha-D-glucosamine-1-phosphate, although this protein is more closely related to archaeal pentose and glucose phosphomutases than to bacterial glucosamine phosphomutases. The thermostable MJ1101 protein catalyzed both the acetylation of glucosamine-1-phosphate and the uridylyltransferase reaction with UTP to produce UDP-GlcNAc. The MMP0705 protein catalyzed the C-2 epimerization of UDP-GlcNAc, and the MMP0706 protein used NAD(+) to oxidize UDP-N-acetylmannosamine, forming UDP-N-acetylmannosaminuronate (ManNAcA). These two proteins are similar to enzymes used for proteobacterial lipopolysaccharide biosynthesis and gram-positive bacterial capsule production, suggesting a common evolutionary origin and a widespread distribution of ManNAcA. UDP-GlcNAc and UDP-ManNAcA biosynthesis evolved early in the euryarchaeal lineage, because most of their genomes contain orthologs of the five genes characterized here. These UDP-acetamido sugars are predicted to be precursors for flagellin and S-layer protein modifications and for the biosynthesis of methanogenic coenzyme B.
Electromagnetic inverse scattering: Retrievable information and measurement strategies (1997)

With reference to inverse scattering from an unknown object of limited extension embedded in a homogeneous background at a fixed frequency, we show that only a finite‐dimensional representation of the unknown contrast can be hopefully retrieved. Exploiting the quasi‐band‐limitedness property of scattered fields, an accurate upper bound to the dimension of such a space is evaluated in both the single incidence and multiview cases. Moreover, effective schemes are given to collect all the information available from the scattering experiments in a nonredundant manner. As a by‐product, an optimal (minimally redundant) sampling strategy for the monostatic radar cross section is also provided. Finally, we briefly discuss how the requirement for a globally effective and reliable solution scheme can lead to a reduction of the actually retrievable information.
Performance analysis of energy consumption in 3GPP networks (2004)

Energy conservation is critical for third generation (3G) cellular systems. In particular, future high-speed packet data services are expected to exhaust the energy of a mobile station rapidly. In 3GPP systems, the radio resource is mainly controlled by the radio resource control (RRC). This paper quantifies the energy consumption and the reconnection ratio for 3GPP systems based on the RRC state machine. Bursty and streaming packet data services are investigated. Through analytic models and comprehensive simulation with various traffic models, the impacts of diverse timer values on the RRC state machine are illustrated. In addition to quantifying energy consumption, appropriate timer values are suggested.
An Enhanced Virtual Fitting Room using Deep Neural Networks (2020)

As the customer's experience in present fit-on rooms is considered as an essential part of the textile industry, these fit-on rooms play a huge role in the textile shops. It is quite an arduous method and generates problems like long queues, having to change clothes individually, privacy problems and wasting time. The proposed convolutional neural network-based Virtual Fit-on Room helps to prevent the above mentioned problems. This product contains a TV screen, two web cameras, and a PC. It captures the customer's body by using two web cameras and displays the customer's dressed body. The combination of CNN in Deep learning and AR processes the body detection and generates the customer's dressed object. The application uses the stereo vision concept to get body measurements. The system detects customer age, gender, face type, and skin tones which are used to recommend cloth styles to customers. Another requirement of this system is customizing styles according to the customer requirements and suggests different styles of clothes. The system achieved 99% accuracy when suggesting different styles using FFNN. Customers can choose clothes for another person who does not physically appear with the customer in the textile shop. The expected output delivers the most realistic dressed object to the customer which allows the efficient customizations for the textile products according to customer requirements. This product can highly influence the textile and fashion industry. Therefore, this product is suitable to compete with other applications in the industry.
Hierarchical spline-based image registration (1994)

The problem of image registration subsumes a number of topics in multiframe image analysis, including the computation of optic flow (general pixel-based motion), stereo correspondence, structure from motion, and feature tracking. We present a new registration algorithm based on a spline representation of the displacement field which can be specialized to solve all of the above mentioned problems. In particular, we show how to compute local flow, global (parametric) flow, rigid flow resulting from camera egomotion, and multiframe versions of the above problems. Using a spline-based description of the flow removes the need for overlapping correlation windows, and produces an explicit measure of the correlation between adjacent flow estimates. We demonstrate our algorithm on multiframe image registration and the recovery of 3D projective scene geometry. We also provide results on a number of standard motion sequences.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
