Virtual integral holography

A range of stereoscopic display technologies exist which are no more intrusive, to the user, than a pair of spectacles. Combining such a display system with sensors for the position and orientation of the user's point-of-view results in a greatly enhanced depiction of three-dimensional data. As the point of view changes, the stereo display channels are updated in real time. The face of a monitor or display screen becomes a window on a three-dimensional scene. Motion parallax naturally conveys the placement and relative depth of objects in the field of view. Most of the advantages of "head-mounted display" technology are achieved with a less cumbersome system. To derive the full benefits of stereo combined with motion parallax, both stereo channels must be updated in real time. This may limit the size and complexity of data bases which can be viewed on processors of modest resources, and restrict the use of additional three-dimensional cues, such as texture mapping, depth cueing, and hidden surface elimination. Effective use of "full 3D" may still be undertaken in a non-interactive mode. Integral composite holograms have often been advanced as a powerful 3D visualization tool. Such a hologram is typically produced from a film recording of an object on a turntable, or a computer animation of an object rotating about one axis. The individual frames of film are multiplexed, in a composite hologram, in such a way as to be indexed by viewing angle. The composite may be produced as a cylinder transparency, which provides a stereo view of the object as if enclosed within the cylinder, which can be viewed from any angle. No vertical parallax is usually provided (this would require increasing the dimensionality of the multiplexing scheme), but the three dimensional image is highly resolved and easy to view and interpret. Even a modest processor can duplicate the effect of such a precomputed display, provided sufficient memory and bus bandwidth. This paper describes the components of a stereo display system with user point-of-view tracking for interactive 3D, and a digital realization of integral composite display which we term virtual integral holography. The primary drawbacks of holographic display - film processing turnaround time, and the difficulties of displaying scenes in full color -are obviated, and motion parallax cues provide easy 3D interpretation even for users who cannot see in stereo.
Los portales del conocimiento en las organizaciones contemporáneas

This essay deals with the importance of a knowledge portal as a tool for the systematic management and harmonious growth of an organization, since it is a technical and management tool which contemporary organizations should have to compete better in an increasingly globalized and post-industrial society where the main competitive advantage is undoubtedly knowledge. Emphasis is given to aspects of administrative nature rather than technical, to introduce the portal as a management tool that facilitates knowledge management. Its consolidation and good success depend on the existence of a collaborative environment among information professionals in the systematic management of organizational knowledge.
Gibbs distributions and Markov random field model: application on background modeling in video surveillance

Recently, backgrounds modeling methods that employ Time-Adaptive, Per Pixel, and Mixture of Gaussians (TAPPMOG) model have become more and more popular owing to their intrinsic appealing properties in video surveillance. Nevertheless, they are not able parse to monitor global changes in the scene, because they model the background as a set of independent pixel processes. In this paper, Gibbs Distributions-Markov Random Field (GDMRF) model is applied to the background modeling, and then the Simulated Annealing algorithm is developed to extract the background from video sequences. Experimental comparison between our methods and a classic pixel-based approach reveals that our proposed method is really effective in recovering from situations of sudden global illumination changes of the background, and can perfectly adapt the object moving in the background.

The effects of harmonic components on transformer losses of sinusoidal source supplying non-linear loads

An important consideration when evaluating the impact of harmonics is their effect on power system component and loads. Transformers are major components in power systems. The increased losses due to harmonic distortion can cause excessive losses and hence abnormal temperature rise. The measurement of iron losses and copper losses of single-phase transformers is important in particular for transformers feeding nonlinear loads. In computing of transformer losses, it is assumed that source voltage is sinusoidal and load impedance is linear. This study presents the effects of harmonic distortion of load current and voltage on single-phase transformer losses utilizing the on-line measurements (monitoring) method of the primary side. The transformer is loaded with an SCR speed controller that consists of a single-phase full-bridge rectifier, SCR and a resistant load to generate various total harmonic current and voltage distortions (THDi and THDv) conditions.
What is better than an 8192x8192 CCD Mosaic imager: two Mosaic wide-field imagers, one for KPNO and one for CTIO

A new generation wide-field imager is being developed and will be put into service at sites in North and South America. Driven by the requirement for larger imaging areas and more pixels but limited by manufacturing process constraints, manufacturers are developing 2, 3, and 4-side buttable CCDs that can be tiled to achieve large imaging areas as opposed to developing a single large CCD. NOAO has designed, fabricated, and tested a wide-field imager called Mosaic that tiles 8 CCDs to produce an imaging area slightly greater than 123 mm X 123 mm. Several successful science observation runs have been completed using Mosaic at the KPNO Mayall 4 m and . 9 m telescopes. A second Mosaic Wide-Field Imager is presently being manufactured and will be deployed at the CTIO Blanco 4 m telescope early next year. This report will focus on the mechanical design aspects of the Mosaic Imager and the upgrade path to achieve the scientific requirements will be discussed.
Red Deer (Cervus elaphus) Hinds Discriminate Between the Roars of Their Current Harem-Holder Stag and Those of Neighbouring Stags

During the period of reproduction red deer stags gather harems and roar loudly and repeatedly, both toward competing stags and toward the hinds that they actively herd. It has been proposed that red deer hinds may actively choose their mate on the basis of a comparison of the roaring rate of competing stags. Hinds may also choose to mate with the male that is most familiar to them, i.e. that male who spent most time and eAort in retaining them within his harem and in roaring at them. Such a mechanism of female choice implies that females are able to discriminate individual characteristics in the stags’ roars. We investigated this possibility by conducting playback experiments based on the habituation‐discrimination paradigm. Our results show that hinds are able to discriminate between the roars of their current harem-holder stag and those of other neighbouring stags and suggest that this ability, a necessity for individual recognition, may be important in female mate choice in red deer.

A GaAs Nanowire Array Solar Cell With 15.3% Efficiency at 1 Sun

A GaAs nanowire array solar cell with an independently verified solar energy conversion efficiency of 15.3% and open-circuit voltage of 0.906 V under AM1.5g solar illumination at 1-sun intensity has been fabricated. This is the highest published efficiency for nanowire array solar cells and is twice the prior record for GaAs nanowire array solar cells. The solar cell has been fabricated by substrate-based epitaxy but is structurally compatible with substrate-less aerotaxy fabrication, providing a path to high-volume manufacturing. The short-circuit current of 21.3 mA/cm2 was generated with axial p-n junction GaAs cores covering 13% of the surface area, which is a volume of GaAs equivalent to a 370-nm-thick planar layer.

Measures Of Concordance Of Polynomial Type 2004

A measure of concordance, κ, is of polynomial type if and only if κ(tA + (1 − t)B) is a polynomial in t where A and B are 2-copulas. The degree of such a type of measure of concordance is simply the highest degree of the polynomial associated with κ. In previous work [2][3], properties of measures of concordance preserving convex sums (equivalently measures of concordance of polynomial type degree one) were established; however, a characterization was not made. Here a characterization is made using approximations involving doubly stochastic matrices. Other representations are provided from this characterization leading naturally to two interpretations of degree one measures of concordance. The existence of a family of measures of concordance of polynomial type having higher degree generated by a certain family of Borel measures on (0, 1) is also shown. The representation of this family immediately leads to a probabilistic interpretation for all finite measures in dn. Also, higher degree analogs of commonly known degree one measures of concordance are given as examples. For the degree 2 case in particular, we see there is no finite μ ∈ d2 generating Kendall’s tau. Finally, another family of measures of concordance is given containing those generated by finite measures in d2 as well as Kendall’s tau.
Perceptions of Firms Learning and Growth under Knowledge Management Approach with Linkage to Balanced Scorecard (BSC): Evidence from a Multinational Corporation of Bangladesh

The study attempts to measure organization’s perception on learning and growth with the help of Balanced scorecard model in a multinational firm of Bangladesh.That is to say, in this paper it has been shown how a proper and effective knowledge management can make possible the organization's financial success that can be revealed using the Balanced Scorecard (BSC) framework. Additionally, the perception about knowledge management , its linkage to the BSC and its usage have been identified. Primary data collected for conducting this emperical research was carried out through survey method using structured questionnaire. Data were then analysed with the help of bi-variate and multi-vatiate techniques of statistics. Empirical results of our study suggest that learning and growing organization is one in which knowledge management activities are deployed and expanded with a view to leverage the creativity of all the people in the organization The result also evidenced that BSC, as a strategic performance measurement tool, helps in strategic management by linking some strategically significant, relevant, and interrelated measures or indicators with organizational emphasis on knowledge and learning initiatives.

Probing signal design for power system identification

This paper investigates the design of effective input signals for low-level probing of power systems. In 2005, 2006, and 2008 the Western Electricity Coordinating Council (WECC) conducted four large-scale system-wide tests of the western interconnected power system where probing signals were injected by modulating the control signal at the Celilo end of the Pacific DC intertie. A major objective of these tests is the accurate estimation of the inter-area electromechanical modes. A key aspect of any such test is the design of an effective probing signal that leads to measured outputs rich in information about the modes. This paper specifically studies low-level probing signal design for power-system identification. The paper describes the design methodology and the advantages of this new probing signal which was successfully applied during these tests. This probing input is a multi-sine signal with its frequency content focused in the range of the inter-area modes. The period of the signal is over 2 min providing high-frequency resolution. Up to 15 cycles of the signal are injected resulting in a processing gain of 15. The resulting system response is studied in the time and frequency domains. Because of the new probing signal characteristics, these results show significant improvement in the output SNR compared to previous tests.
Photocatalytic Water Splitting on Ni-Intercalated Ruddlesden−Popper Tantalate H2La2/3Ta2O7

A series of Ruddlesden−Popper-type hydrous layered perovskites, ATa2O7 (A‘ = H or K, A = La2/3 or Sr), were presented as novel catalysts for photocatalytic water splitting into H2 and O2 under UV irradiation. These hydrous perovskites showed higher activity than anhydrous perovskites (KTaO3, La1/3TaO3) for overall splitting of water. Results of photoluminescence spectroscopy and H2 evolution from aqueous n-butylamine solution support the hypothesis that the high activity of the hydrous perovskites results from their hydrated layered structure, where the photogenerated electrons and holes can be effectively transferred to the intercalated substrates (H2O and n-butylamine). Addition of Ni cocatalyst to H2La2/3Ta2O7 via an ion-exchange reaction increased the activity, while Ni addition did not improve the activity of H2SrTa2O7. Ni K-edge EXAFS/XANES, UV−vis spectroscopy, and TEM results for Ni-loaded catalysts indicate that Ni2+ ions and small NiO clusters are intercalated into the layers of H2La2/3Ta2O7, wh.
The worldwide incidence of preterm birth: a systematic review of maternal mortality and morbidity.

OBJECTIVE To analyse preterm birth rates worldwide to assess the incidence of this public health problem, map the regional distribution of preterm births and gain insight into existing assessment strategies. METHODS Data on preterm birth rates worldwide were extracted during a previous systematic review of published and unpublished data on maternal mortality and morbidity reported between 1997 and 2002. Those data were supplemented through a complementary search covering the period 2003-2007. Region-specific multiple regression models were used to estimate the preterm birth rates for countries with no data. FINDINGS We estimated that in 2005, 12.9 million births, or 9.6% of all births worldwide, were preterm. Approximately 11 million (85%) of these preterm births were concentrated in Africa and Asia, while about 0.5 million occurred in each of Europe and North America (excluding Mexico) and 0.9 million in Latin America and the Caribbean. The highest rates of preterm birth were in Africa and North America (11.9% and 10.6% of all births, respectively), and the lowest were in Europe (6.2%). CONCLUSION Preterm birth is an important perinatal health problem across the globe. Developing countries, especially those in Africa and southern Asia, incur the highest burden in terms of absolute numbers, although a high rate is also observed in North America. A better understanding of the causes of preterm birth and improved estimates of the incidence of preterm birth at the country level are needed to improve access to effective obstetric and neonatal care.
Feasibility of HgBrI as photoconductor for direct X-ray imaging

Films of HgBrI (eutectic composition) were grown by the physical vapor deposition method on palladium-coated glass substrates 2''times2'' in size. The growth was performed in a system especially designed and constructed for getting a fine control of the growth parameters. The best growth conditions were a source temperature of 116degC, a growth temperature of 40degC and a growth time of 3 h, with an initial pressure of 6times10-3 Pa. Film thicknesses and grain sizes gave values ranging between 100 and 350 mum (10%), and between (10plusmn5) and (50plusmn20) mum, respectively. The dark current density of the films is higher than 10 pA/mm2 (maximum value required for the application) for electric fields above 0.03 V/mum, and the resistivity is 3.8times1011 Omega.cm. Electron and hole mobility-lifetimes of 7.1times10-6 cm2/V y 1.0times10-5 cm2/V were estimated. HgBrI films give a sensitivity to X-rays of 65 nC/Rmiddotcm2 for an X-ray beam of 70 KVp, with an electric field of 0.25 V/mum applied to the film. Taking into account that this is the first attempt on growing films with this material, these results indicate HgBrI as a new compound semiconductor candidate for the application
Sodium Nitroprusside Toxicity in a Young Infant Following Cardiac Surgery

Adverse effects associated with sodium nitroprusside (SNP) administration are rarely observed in children. Monitoring of metabolic changes appears to be the most sensitive and accurate indicator of early toxicity. We report a case of acute toxicity in a 3-month-old boy treated with high-dose SNP infusion for systemic hypertension after elective coarctectomy, who developed seizures and severe lactic acidosis. We suggest blood lactate levels and base excess levels should be carefully monitored during SNP treatment in children, in order to detect early signs of toxicity, particularly when using high infusion rates.

Fatty acids, health indices and sensory properties of Ricotta cheese from sheep fed three different diets

The study evaluates the healthy fatty acids profile and sensorial characteristics of ricotta obtained from ewes fed three different diets: diet enriched with linseed (L), un-supplemented diet (F) and pasture (P). Omega−3 fatty acids (N-3 FAs) levels in ricotta from grazing sheep and from animals that received the supplemented diet were notably higher than those that received un-supplemented feed. The L and P groups had lower levels of saturated fatty acids (SFAs), higher levels of conjugated linoleic acid (CLA) and more favourable health indices. Sensorial tests showed that among the diet groups, the ricotta obtained from the supplementation group scored the highest with respect to greasiness, spreadability and acceptability
International Diabetes Center Treatment of Type 2 Diabetes Glucose Algorithm

SUMMARY With the growing worldwide diabetes epidemic, the management of individuals with Type 2 diabetes (T2D) will, out of necessity, be undertaken more by primary-care health providers and less by subspecialist diabetologists. To overcome the barriers to effective management of T2D, we will need to address the issue of clinical inertia by providing healthcare professionals with pragmatic evidence-based algorithms. The International Diabetes Center (MN, USA) has created an algorithm for T2D, which is customizable to local conditions and fosters discussion between the patient and provider of the risks and benefits of the different therapeutic options. Using clinical evidence coupled with clinical experience, it establishes a glycemic target-driven systematic, multidiscipline team approach to initiate and advance T2D therapies by addressing the underlying pathophysiological defects associated with T2D.
Effects of 2,2-Dichlorovinyl Dimethyl Phosphate (DDVP) on Hsp70 Gene Expression in Rainbow Trout

Dichlorovinyl dimethyl phosphate (DDVP) is used to control insects on crops, household, and stored products, and treat external parasitic infections in farmed fish, livestock, and domestic animals. Ectoparasitic copepods can cause severe skin damage in fish that may lead to death through osmoregulatory failure or infection by opportunistic pathogens. There is considerable uncertainty about whether or not DDVP is implicated in cancer, and the wider environmental con- sequences of its use. In general, and specifically in developing countries and fish farming, less hazardous alternatives are available. The present experiment studied the effects of DDVP at a daily dose of 1.6 mg/l for 21 days on the expression of the heat shock protein (Hsp) 70 gene in rainbow trout (Oncorhynchus mykiss). Hsp70 from control and DDVP-exposed fish was ampli- fied for 20-40 PCR cycling. After the fortieth PCR cycle, the Hsp70 level in mRNA was very low in the control fish and very high in the DDVP-exposed fish, with a statistical difference of p<0.01.
Simulation for Optical Response of High-Speed Traveling Wave Electro-Optic Polymer/TiO2 Multilayer Slot Waveguide Modulators

In this paper, we analyze a traveling wave electrode as it drives a high-speed electro-optic (EO) polymer/TiO 2 multilayer slot waveguide modulator by simulation. To enhance its mode confinement, the EO polymer is clipped by TiO2 slot waveguide films, and the electrode atop the active region and connection transmission line are optimized to match the impedance at 50 Ω. The optical response is over 200 GHz at 3-dB bandwidth with a 1-cm-long electrode. By comparison, the optical response with silicon TiO2 layers is only 20 GHz with transverse electric (TE) polarized light.
