Sistema de realidad aumentada aplicado al juego de billar

Para este proyecto se creo un sistema de realidad aumentada aplicado al juego de billar, con el objetivo de analizar el modelamiento matematico de las trayectorias que podrian seguir las bolas y luego trazar dichas trayectorias calculadas sobre la mesa de billar. La construccion de un sistema de realidad aumentada para el juego de billar ofrece una amplia gama de posibilidades y variables que lo hacen pertinente para realizar analisis sobre el medio en una interaccion directa y en “tiempo real”, lo que hace ademas que la experiencia sea llamativa. Igualmente, la cantidad de habilidades y destrezas que hay que poseer y desarrollar para la implementacion de un sistema de este tipo hacen que dicho trabajo aporte de forma substancial a la construccion de un conocimiento concreto en torno a la realidad aumentada y sus aplicaciones. El sistema fue desarrollado para ejecutar carambolas efectivas por medio de la ayuda que presta tener la trayectoria dibujada sobre la mesa antes de realizar la tacada. Para lograrlo, el sistema de realidad aumentada requiere de un dispositivo de adquisicion de datos, en este caso una camara de video–, un software para el procesamiento de la informacion, un sistema de proyeccion de las trayectorias y una mesa de billar en donde se va a crear la proyeccion y donde se va a ejecutar la carambola trazada por el programa. El manejo de los conceptos propios de los fenomenos fisicos inmersos en el juego del billar es tambien prioritario para el desarrollo de este proyecto, debido a que es fundamental valorar las propiedades del medio al que se pretende aplicar el sistema de realidad aumentada. Otras de las destrezas necesarias para la construccion de un sistema de realidad aumentada son la creacion de algoritmos, su programacion y el conocimiento del lenguaje en el software MatLab, cruciales tanto para la elaboracion como para asegurar la efectividad del sistema a disenar.
A convolutional neural network architecture for vehicle logo recognition

In order to achieve the significant vehicle logo recognition, a novel convolutional neural network(CNN) architecture is proposed. Considering the complexity of high dimensional data, we employ inception architecture and build a deep CNN network, which reduces the data dimensions and accelerates the computation of a large number of samples. We prepare a dataset to evaluate our algorithm, and obtain an overall accuracy of 99.02%. The comparison results show that our proposed algorithm outperforms linear support vector machine (SVM), LeNet-5, ImageNet and GoogLeNet in terms of accuracy improvement and computation-time reduction.
Half-Bridge and Full-Bridge Choke Converter Concepts for the Pulsed Operation of Large Dielectric Barrier Discharge Lamps

The paper presents a new configuration of electronic ballast for large dielectric barrier discharge lamps used in backlighting applications. The new ballast is developed for PLANON lamps, manufactured by Osram. This lamp features environmental friendliness, a long lifetime and no startup time due to external electrodes and a mercury-free Xenon gas mixture. The mainly used ballast topology is the Class-E converter. Two novel ballast topologies-the half-bridge and the full-bridge choke converter concepts-are demonstrated. Measurement results of the proposed topologies under variation of input parameters are presented. An isolated metal oxide semiconductor field effect transistor drive concept which fulfills the requirements of the ballast is developed and implemented. An equivalent circuit diagram for the lamp is determined and compared with measurement results. The proposed topologies can significantly increase the lamp's luminous efficacy compared to Class-E topology
An optocouplerless two-stage high power factor LED driver

An optocouplerless two-stage high power factor LED driver is proposed in this paper. The first stage is an optocouplerless isolated PFC converter and the second stage is a constant-current controlled non-isolated DC/DC LED driver. Optocoupler and secondary amplifier circuit of the first PFC stage can be removed. Besides, the output capacitor s of the PFC stage can be reduced due to low output ripple voltage requirement and acceptable wide input voltage range of the secondary stage in the two-stage LED driver. Hence the circuit structure of the proposed optocouplerless two-stage high power factor LED Driver is much simplified. A prototype LED driver for 12W LED fluorescent tube is built up to verify theoretical analysis and experiment results are presented.
TDH2 is linked to MET3 on chromosome X of Saccharomyces cerevisiae

The MET3 gene of Saccharomyces cerevisiae was cloned and its restriction map was found to differ in the upstream region from an earlier published map (Cherest et al. Gene 34, 269–281, 1985) and nucleotide sequence (Cherest et al. Mol. Gen. Genet. 210, 307–313, 1987). Southern blot analysis of genomic DNA from strains S288C and FL100 (the genetic backgrounds from which these different copies of the gene had been cloned) showed that our clone from a S288C‐based library had the same restriction map as the chromosomal DNA from both of the strains. Comarison of the nucleotide sequence of the two clones indicated that the earlier published clone probably represented a cloning artifact. In our clone, we found upstream of MET3, the nucleotide sequence of the TDH2 gene (Holland and Holland, J. Biol. Chem. 255, 2596–2605, 1980). The chromosomal orientation of the two genes was determined to be MET3–TDH2–CEN10.

Model-driven framework to support evolution of mobile applications in multi-cloud environments

Purpose The development of mobile applications in multiple clouds environment is a complex task because of the lack of platform standards in cloud computing and mobile computing. The source code involves various proprietary programming libraries for different platforms. However, functionalities are inevitably changed over time, as well as the platform. Therefore, a great deal of development effort is required, when changes need to be made at functional and platform level. This paper aims to propose SIMON, a framework that eases complexity of the development to support software evolution. Design/methodology/approach SIMON shields the developer from the complexity of mobile and cloud platforms in the development of mobile applications in multiple clouds environment. The framework uses model of application design to automate the development and support execution of mobile applications in system environment that needs integration to the number of data sources located on multiple clouds. The framework is composed of prefabricated components that support function changeability and platform adaptability. Findings The framework is examined with the development of a sample application. After it is evaluated with scenarios that involve changing at functional and platform levels, the result shows significant reducing of the development effort by comparing with the other approaches. Originality/value The framework facilitates the implementation of mobile applications in the software system that involves integration to multiple clouds, and it supports software evolution with lesser development effort.
Diagnosable versus Distinct: Evaluating Species Limits in Birds

Abstract I review new species of birds described from 1993 to 2002, comparing the methods used to diagnose (identify) new bird species with those used for other classes of vertebrates. Birds are described and subsequently identified using a far more restrictive set of criteria than other organisms, with field diagnosability being the ultimate criterion of distinctiveness. This has led to a large number of evolutionarily distinct bird taxa that are not recognized as distinct taxonomic units. This disparity has important consequences for ornithology and for other disciplines that use birds as biodiversity measures.
Genome-free viral capsids as multivalent carriers for taxol delivery.

Drugs used in chemotherapy predominantly act by targeting the mechanisms of cell division, 1 and to an extent, preferentially affect cancer cells because of their unusually high proliferation rates. Unfortunately, many healthy cells are also affected by these treatments, resulting in side effects that cause substantial discomfort for the patient. Emerging methods seek to focus the delivery of drugs on cancer tissue by targeting specific characteristics found in solid tumors.2 As a promising subset of these approaches, macromolecular drug delivery seeks to attach many small molecule drugs and targeting groups to large structures.3 Many of these delivery vehicles experience prolonged circulation time because of their increased size,4 as well as a degree of passive targeting through the enhanced permeation and retention effect, arising from unique characteristics of tumor vasculature.5 As an additional benefit, macromolecules are large enough to display multiple copies of active targeting ligands to enhance binding avidity,6 and can also provide multiple cargo attachment sites to increase the amount of payload that can be delivered.
Serum 25-hydroxyvitamin D and incidence of fatal and nonfatal cardiovascular events: a prospective study with repeated measurements.

CONTEXT Several studies suggested that low serum concentrations of 25-hydroxyvitamin D (25(OH)D) are associated with an increased risk of cardiovascular disease (CVD). However, the evidence is still inconclusive, mostly based on CVD mortality and studies with single 25(OH)D measurements. OBJECTIVE We aimed to assess the association of 25(OH)D with fatal and nonfatal CVD in the same study population, using repeated 25(OH)D measurements and competing risks analysis. DESIGN This was a population-based cohort study (ESTHER study, baseline 2000-2002). Follow-up data, including survival status, were collected after 2, 5, and 8 years. The response rate for survival was 99.9%. SETTING Participants were recruited during a health screening examination by their general practitioners. 25(OH)D was measured in blood samples collected at baseline and the 5-year follow-up visit. PATIENTS OR OTHER PARTICIPANTS A total of 9949 men and women, aged 50 to 74 years at baseline, with sufficient knowledge of the German language and resident in the German state of Saarland were included in the study. MAIN OUTCOME MEASURES Outcomes included CVD, coronary heart disease (CHD), and stroke, in total and differentiated into fatal and nonfatal events. RESULTS Overall, 854 study participants had a nonfatal and 176 a fatal CVD event during 8 years of follow-up. Comparing subjects with 25(OH)D levels below 30 nmol/L and above 50 nmol/L resulted in a hazard ratio of 1.27 (95% confidence interval = 1.05-1.54) for total CVD and 1.62 (95% confidence interval = 1.07-2.48) for fatal CVD in a model adjusted for important potential confounders. No significant association for nonfatal CVD was observed. In dose-response analysis, we observed an increased cardiovascular risk at 25(OH)D levels below 75 nmol/L. Results for CHD and stroke were comparable to the results obtained for the composite outcome CVD. CONCLUSIONS Our results support evidence that low 25(OH)D levels are associated with moderately increased risk of CVD and indicate that the observed association is much stronger for fatal than for nonfatal events.
The software development workbench WSDW

This paper presents the architecture and some tools of the software development workbench WSDW. The authors propose a structure-oriented workbench, in which interactive software tools are integrated through sharing a unique high level program representation, satisfying the request of independence from the source language. The data structure representing programs, the web structure, is based upon the mathematical concept of relation and it is easily implemented as a Prolog data base. Program transformations, given as web transformations, can be expressed as rewriting rules, so that software tools can be implemented as sets of rewriting rules and then added to the WSDW. <<ETX>>
On Sobolev Theorem for Riesz-Type Potentials in Lebesgue Spaces with Variable Exponent

The Riesz potential operator of variable order fi(x) is shown to be bounded from the Lebesgue space L p(¢) (R n ) with variable exponent p(x) into the weighted space L q(¢) ‰ (R n ), where ‰ = (1 + jxj) i∞ with some ∞ > 0 and 1 q(x) = 1 p(x) i fi(x) n when p(x) is not necessarily constant at inflnity. It is assumed that the exponent p(x) satisfles the logarithmic continuity condition both locally and at inflnity and 1 < p(1) • p(x) • P < 1; x 2R n .
Factors Associated with EHR User Satisfaction in Small Clinic Settings

The research on electronic health record (EHR) user satisfaction has been mainly studied in a complex work environment such as hospitals. Little is known about the EHR user satisfaction in small clinic settings. In this study, we investigate factors associated with EHR user satisfaction is small clinic settings. We use the absorptive capacity lens at an end-user level to understand how small clinics can effectively implement EHR systems and improve user satisfaction. We identify three important factors that are critical for EHR user satisfaction in small clinics: (i) Managerial IT knowledge as manifested in clinical management support , (ii) technological training (informal and formal) as indicated by EHR training , and (iii) IT infrastructure capability operationalized as EHR quality . We propose a research model and associated hypotheses for our research and present current status of our research project.
The relationship between locus of control and teacher burnout.

Summary. The purpose of this research was to investigate the relationship between locus of control, as measured by the Nowicki-Strickland Adult Scale, and burnout as measured by the Maslach Burnout Inventory (MBI). A survey form containing these instruments was mailed to all special education teachers in 28 school districts in the north-eastern United States. Of the initial 684 mailings, 469 were returned (69 per cent). An analysis of the data using Pearson product-moment correlations revealed significant correlations between increasingly external locus of control orientation and increased perceptions of burnout on four of the six subscales of the MBI. Findings are discussed and a suggestion for future research presented.
A Rapid Primary Screening Method for Antitumor Using the Oomycete Pythium aphanidermatum

Investigating bioactive components from microbial metabolites can provide potential source for drug discovery. There are a number of traditional antitumor compounds screening assays already described. In this study, we have developed an efficient method to search for antitumor compounds using the Oomycete Pythium aphanidermatum as model on agar plates for high throughtput screening. Antioomycete compounds showed cytotoxic effects in human cancer cells lines due to the possible similarity between the lipid cell membrane of the Pythium species and cancerous cells, suggesting the compounds act through similar mechanisms of inhibition. In this assay, it is possible to evaluate hundreds of samples, with results in few hours. The Pythium assay was shown to be sensitive for several chemical substances and allowed the detection and isolation of antitumor compounds from microorganisms. This bioassay was shown to be sensitive, rapid, simple and reliable for antitumor activity. It takes just few hours to evaluate the properties of the extracts.
An Optofluidic Concept for a Tunable Micro-iris

A tunable aperture stop based on optofluidic technology, which overcomes a number of limitations of comparable micromechanical alternatives, is presented. Relying on the high optical absorption of aqueous pigment dispersions, we demonstrate that optical stops of high contrast may be defined without the need for any movable parts. The highly flexible design is based on photolithographic patterning of dry film resist and allows control of laminar flow in microfluidic chambers exclusively by capillary forces. The functionality of the developed device is shown in transmission measurements and by application of the iris in a basic imaging setup.
Boosting of HIV-1 Neutralizing Antibody Responses by a Distally Related Retroviral Envelope Protein

Our knowledge of the binding sites for neutralizing Abs (NAb) that recognize a broad range of HIV-1 strains (bNAb) has substantially increased in recent years. However, gaps remain in our understanding of how to focus B cell responses to vulnerable conserved sites within the HIV-1 envelope glycoprotein (Env). In this article, we report an immunization strategy composed of a trivalent HIV-1 (clade B envs) DNA prime, followed by a SIVmac239 gp140 Env protein boost that aimed to focus the immune response to structurally conserved parts of the HIV-1 and simian immunodeficiency virus (SIV) Envs. Heterologous NAb titers, primarily to tier 1 HIV-1 isolates, elicited during the trivalent HIV-1 env prime, were significantly increased by the SIVmac239 gp140 protein boost in rabbits. Epitope mapping of Ab-binding reactivity revealed preferential recognition of the C1, C2, V2, V3, and V5 regions. These results provide a proof of concept that a distally related retroviral SIV Env protein boost can increase pre-existing NAb responses against HIV-1.
Thalassemia and Pregnancy

Thalassemia syndromes, hemoglobinopathies characterized by anemia secondary to genetic defects of hemoglobin, are the most common of the genetic blood disorders. The prevalence and severity of the thalassemia syndromes are population dependent, with the type of thalassemia seen dependent on racial background. The health care provider must recognize the woman at highest risk for thalassemia and initiate appropriate screening and diagnostic testing. The specific thalassemia dictates the potential maternal, fetal, and neonatal consequences of anemia, red blood cell dysfunction, and systemic oxygenation issues. This article discusses normal globin chain synthesis, diagnostic testing for thalassemia, plan of management, and implications for the woman and fetus.
Mantis: definición de un entorno para la gestión del mantenimiento de software

En esta tesis se presenta una propuesta que pretende ayudar a mejorar la manera en que las organizaciones llevan a cabo el manteniemiento del software incidiendo en la mejora de la gestion de los proyectos. El punto de vista fundamental de esta propuesta es abordar el problema del mantenimiento desde una perspectiva de "procesos de negocio", integrando los aspectos puramente ingenieriles (del software) con los organizacionales y de gestion. La propuesta esta basada en un nuevo concepto, llamado "Entorno de Ingeneria del Software (EIS) extendido", que integra y amplia los conceptos tradicionales de metodologia y de EIS. Un EIS extendido es una coleccion de herramientas conceptuales, metodologicas y tecnicas cuya finalidad es poder abordar los procesos software desde una perspectiva global de proceso de negocio. En base a las ideas anteriores, en esta tesis se define el Entorno MANTIS, cuyas principales caracteristicas son: integracion por medio de herramientas, orientacion a procesos, especializacion en mantenimiento, y escalabilidad y adaptabilidad. Las tres clases de elementos del Entorno MANTIS son: 1,- Un marco de trabajo conceptual para la gestion de proyectos de mantenimiento, que engloba una arquitectura conceptual multinivel basada en el estandar MOF, un sistema de procesos basado en los estandares ISO, una coleccion de ontologia (del mantenimiento, de los flujos de trabajo, y de la medida), y una coleccion de metamodelos representados en forma de documentos XML, DTD o XMI. 2,- Una colecccion de procedimientos para los procesos de gestion y organizacionales, que complementan y mejoran la metodologia MANTEMA (especializada en el proceso de mantenimiento). 3,- Una coleccion de prototipos definidos como componentes software del Entorno. Se establecen tres tipos de componentes: verticales (para automatizar un determinado tipo de actividad), horizontales (que dan soporte a todo el Entorno), y externas (puede
Treatment non-adherence among patients with poorly controlled type 2 diabetes in ambulatory care settings in southwestern Nigeria.

BACKGROUND Poor adherence to prescribed therapy among patients with chronic diseases is a growing concern which undermines the benefits of current medical care. OBJECTIVES To evaluate the pattern of treatment non-adherence among ambulatory patients with poorly controlled type 2 diabetes in southwestern Nigeria, and to determine the possible factor(s) that accounted for such non-adherence with a view to identifying areas of future intervention to improve outcome. METHODS A prospective cross-sectional interview using the concept of RIM (Recognize, Identify and Manage) model was used to evaluate adherence to treatment recommendations among 176 consented patients recruited from the endocrinology out-patient clinics of two teaching hospitals in southwestern Nigeria between November, 2010 and January, 2011. RESULTS Overlaps of non-adherence behavior were obtained. More than three-quarter (153; 88.4%) were not aware of indication for each of the prescribed medications, 26 (15.3%) correctly described regimen as prescribed. The factorsidentified as possible barriers to medication adherence include practical (145; 40.1%), knowledge (103; 28.5%), and attitudinal (114; 31.5%) barriers. Dietary non-adherence was mostly due to inappropriate guidance (62; 33.7%). CONCLUSIONS The arrays of non-adherence behavior among the cohort further emphasize the need for patient-centered approach as a reasonable strategy in resolving non-adherence problems in routine clinical practice.
What is the rationale for the use of granulocyte and granulocyte-macrophage colony-stimulating factors in the neonatal intensive care unit?

UNLABELLED Neonatal sepsis remains an unsolved major contributor to morbidity and mortality. In the 1980s the promise of augmenting immune function using pooled intravenous gammaglobulin to supplement the exceedingly low levels of immunoglobulin G in premature infants failed to demonstrate a clear advantage. Similarly, cytokine augmentation of cellular function in the 1990s largely appeared to be suffering the same fate. However, both results may arise from a problem in experimental design where the combination of both treatments may be necessary along with specific antibody. For example, in vitro, independently of an array of other humoral and cellular immature immune system issues, opsonization of bacteria is improved in the presence of antibody. The question is whether the same result can be achieved in vivo. No experiments have been reported that directly test this hypothesis. CONCLUSION More investigation is needed in this challenging area of neonatal research.
