Charge packet evolution in paper-oil insulation and derived technological considerations

Focused on the analysis of charge packet evolution in paper-oil insulation for DC cables application, the article tries to identify some parameters derived from PEA measurements, able to characterize accurately the phenomena associated with charge generation under certain poling conditions, but depending also on specific species mobility and local electric stress, consequent to the manufacturing process of the dielectric material.
VASODILATOR EFFECT OF OCTYLMETHOXYCINNAMATE ON HUMAN UMBILICAL ARTERIES

Octylmethoxycinnamate (OMC) is a filter for ultraviolet B radiation used in sunscreens to protect skin. There is some evidence about the OMC activity as endocrine disruptor concerning a possible estrogenic activity, but its vascular effects were not still analyzed. The objective was to evaluate the non-genomic effects of the OMC on human umbilical artery (HUA) without endothelium. By mean of an organ bath system, HUA rings without endothelium were contracted by 5-hydroxytryptamine (5HT; 1µM) or by depolarization with KCl (60mM), and the effect of different concentrations of OMC was analyzed. The OMC elicits vasodilator effect on HUA without endothelium contracted by 5-HT (1μM) and by KCl (60mM). The effect was similar for the two contractile agents used. Here, we established that the OMC causes vasodilation of human arteries. This effect is analogous to the non-genomic effect caused by estradiol (E2), which occurs also by and endothelial-independent mechanism.
Cramer–Rao bound of parameters estimation and coherence performance for next generation radar

In this study, a general signal-processing architecture is proposed for next generation radar (NGR). When the NGR works in MIMO mode, we derive the closed-form Cramer–Rao bound of the estimation of coherent-processing parameters, which include the time-delay differences and phase synchronisation errors among different apertures. When the NGR turns to work in fully coherent mode, assuming the time-delay differences are ideally compensated, the authors present the closedform signal-to-noise ratio (SNR) gain and analyse the SNR gain loss of the NGR because of inaccurate phase synchronisation errors.
Considerations in the Diagnosis and Treatment of Morton’s Entrapment: A Review

Intermetatarsal neuromas, known by their eponym as Morton’s neuromas, are a common painful forefoot pathology seen in the foot and ankle clinic. The nomenclature of this condition is misleading. The term “neuroma” refers to a non-degenerative nerve injury. The condition clinicians most often describe in a “Morton’s neuroma” is more accurately described as a perineural fibrosis of the plantar interdigital nerve leading to entrapment of this nerve [1]. Surgical treatment varies from entrapment release to full neurectomy [2]. Post-operative pathology review of neurectomized tissue rarely demonstrates axonal degeneration and collagen proliferation [3]. Those changes are the pathophysiological markers associated with nerve injury that lead to true neuroma formation. The authors, therefore, recommend changing the common name of the condition from “intermetatarsal neuroma” to interdigital nerve entrapment to better define the disease. The aim of this review is to present treatment schemes seen in “Morton’s” diagnosis, and to suggest an algorithm which may improve patient outcome.
Métodos para la detección oportuna de cáncer cervicouterino

Cervical cancer affects a great portion of the world’s female population,and it became the third cause of death for women in developing countries such as CostaRica.The most common method to diagnose this cancer is the Papanicolaou testor Papsmear; nevertheless, high levels of sensitivity and specificity are required. Consequently, different organizations have developed multiple methods to detect and classify this cancer. This article is divided in three sections: the first one focuses on the general impact of cervical cancer has hadin CostaRica, these condsection gathers information about different methodologies used around the world to detect this cancer and the third one makes reference to the current development of the screening devise in Mexico that works as a monitoring system and can used by women without external assistance.
Use of time-of-flight 3D camera in volume measurement

This paper introduces a way to apply Time-of-Flight (TOF) 3D camera in volume measurement for a stockpile. Two methods, passive and active (reflector based), were used for measuring volume. In the volume calculation algorithm, Delaunay triangulation was applied. This paper also discusses characteristics of the camera and therefore accuracy of the system.
The Transition of Experienced Pilots to a Frequency-Separated Aircraft Attitude Display

Independent groups of eight professional pilots each were given one flight in a Link GAT-2 simulator and one flight in a Beechcraft C-45H using, respectively, the moving horizon, moving airplane, and frequency-separated attitude displays. The flight tasks performed by the subjects included recovery from unknown attitudes, disturbed attitude tracking, and completion of an area navigation course. Data collected in the C-45H aircraft demonstrated superior performance of both the frequency-separated and moving horizon displays when compared to the moving airplane display during unknown attitude recoveries. The frequency-separated display was superior to all others during disturbed attitude tracking. It was concluded that the flight performance of experienced pilots during their initial transition to a frequency-separated flight attitude presentation is at least comparable, and for some tasks superior, to their flight performance with the conventional moving horizon presentation.
THE IMPACT OF THE SPACE ENVIRONMENT ON SPACE SYSTEMS

We have undertaken a study to determine the impact of the space environment on space systems. Known impacts include mission outages, mission degradation and mission failure, launch delays, redesign and retest, anomaly analyses, and the ultimate cost for each of the preceding. We are attempting to quantify these impacts whenever possible. This task is made difficult because impacts are rarely formally documented. We reviewed a variety of sources for anomaly impact information. These sources include anomaly reports from the archives of the Space Sciences Department of The Aerospace Corporation and other organizations, written and oral information from other staff members of The Aerospace Corporation, and contractor reports and published documents relating to spacecraft anomalies. The study provides a good indication of the quality and quantity of the data available. It will also determine the degree to which it is possible to obtain impact information for historical anomalies. In this paper we summarize the results of the study. We emphasize those causes for which it may be possible to provide predictive information such as surface charging, internal charging and the single event upsets that accompany solar proton events.
Analysis of Structure, Composition and Growth of Semiconductor Nanowires by Transmission Electron Microscopy

Nanowires have the potential to be a very flexible platform for the design of semiconductor devices. In nanowires it is possible to form crystal structures not found in the bulk materials under normal conditions, and to combine different III-V and group IV materials into axial or radial heterostructures. As quite complex structures can be formed, both intentionally and unintentionally, characterization of the crystal structure and composition is important. In this thesis, various transmission electron microscopy techniques are presented for this purpose. High resolution imaging can directly visualize the crystal structure, including twinning and stacking faults. The polar nature of the III-V materials leaves one more parameter to be determined. In order to determine polarity from high resolution images it is not only necessary to improve the resolution further by aberration correction, but in addition the local orientation of the sample must be determined. Convergent beam electron diffraction is an alternative method with much lower demands on the microscope and operator, and can be adapted to suit most materials and crystal structures. Transmission electron microscopy also provides several methods for determining and mapping the composition of the nanowires. It is important in all cases to avoid damaging the nanowires during the acquisition of the analytical signal. In the most commonly used method, energy dispersive X-ray spectroscopy, this can be achieved by spreading the electron dose over as large an area as possible. If there is only a single unknown parameter for the composition, alternative methods such as the shift in plasmon energy with composition can be used instead, as they have higher collection efficiencies. In order to improve the nanowires in terms of crystal structure and composition, these must be connected to the dynamic processes occurring during growth. Occasionally these processes can be inferred from the fully formed nanowires after growth, but ideally one would like to observe the growth in-situ in the microscope. This is usually possible only with highly specialized environmental microscopes. In this thesis, nanowire growth in much simpler closed cells is demonstrated. Although the growth conditions could neither be precisely measured nor controlled, the closed cells made it possible to observe for the first time growing InAs nanowires in-situ in a conventional transmission electron microscope.

Factores relacionados con el éxito del mantenimiento productivo total

Total Productive Maintenance (TPM) is one tool widely used in production areas, aimed at increasing the availability of machinery and equipment production and economic benefits of businesses. However, do not know the key success factors for it implementation. This article presents the results of a survey that consisted of 84 questions and was applied to maintenance managers and supervisors of companies located in Ciudad Juarez, which should be answered on a Likert scale. Exploratory factorial analysis (EFA) was applied to information through the method of principal components and a varimax rotation was conducted and found that only 3 factors could explain the 65,06% of total variance, related to managerial commitment, cleanup culture and integration of operators in maintenance decisions. We also performed a confirmatory factor analysis (CFA) to validate the results, confirming the findings in EFA.

A novel tunable microwave filter integrated power dividers using liquid crystal

This article presents design considerations of a tunable microwave filter integrated power divider based on highly anisotropic liquid crystals (LCs), which helps to reduce the circuit size. The proposed device comprising a thin LC layer between a ground plane and a directly coupled inverted microstrip line exhibits the equal power splitting function with a tunable bandpass response. The integrated device results in sharp rejection and smaller circuit area, as compared with the cascaded connection of an equal power divider and tunable microwave filter. © 2015 Wiley Periodicals, Inc.

Using parallel windings in planar magnetic components

The use of parallel windings is a very common practice in planar magnetics, where the copper thickness is usually very low to handle typical current values. Besides, the use of parallel turns allows applying better interleaving among the different windings. This work presents a review of the proper modeling strategy in order to take into account the current distribution through each paralleled winding. Different winding strategies have been analyzed using a finite element analysis (FEA) based model in order to obtain the proper procedure to place parallel windings in planar magnetics. Although the modeling strategy presented is valid for any winding strategy (planar and concentric), it has been applied in order to test planar components.
Harmonic Optimization Techniques in Multi-Level Voltage-Source Inverter with Unequal DC Sources

One of the major problems in electric power quality is the harmonic contents. There are several methods of indicating the quantity of harmonic contents. The most widely used measure is the total harmonic distortion (THD). Various switching techniques have been used in static converters to reduce the output harmonic content. This paper presents and compares the two harmonic optimization techniques, known as optimal minimization of the total harmonic distortion (OMTHD) technique and optimized harmonic stepped-waveform (OHSW) technique used in multi-level inverters with unequal dc sources. Both techniques are very effective and efficient for improving the quality of the inverter output voltage. First, we describe briefly the cascaded H-bridge multi-level inverter structure. Then, we present the switching algorithm for the inverter based on OHSW and OMTHD techniques. Finally, the results obtained for the two techniques are analyzed and compared. The results verify the effectiveness of the both techniques in multi-level voltage-source inverter with non-equal dc sources, clarifying the advantages of each technique.
Advances in Design Methodology for Landslide Repair Using Launched Soil Nails

Ballistic soil nails have been used in the United States to repair shallow roadway landslides for nearly 20 years. The U.S. Forest Service/Federal Highway Administration Application Guide for Launched Soil Nails is the principal design manual for designing with ballistic soil nails and employs a simplified sliding wedge analysis using limit equilibrium concepts to determine the factor of safety of a slope reinforced with soil nails. The design methodology quantifies the tensile and shear resistance provided by the individual nails, but is simplistic and is limited to linear failure surfaces in homogenous materials. This paper explains some of the recent advancements in launched soil nail design methodology including the new program LSNAP (Launched Soil Nail Analysis Program) which builds on previous efforts (SNAP - Federal Highway Administration) to accurately and efficiently quantify the tensile and shear contribution of ballistic soil nails in a global stability analysis.
Sizing a switched reluctance motor for electric vehicles

This paper proposes a methodology to determine the peak and continuous power ratings of a switched reluctance motor (SRM) used for the electric propulsion of an Electric Vehicle (EV). The input data consist of the EV main specifications (e.g., rated and maximum velocities, vehicle mass, city and highway driving schedules, etc.). Estimation of the variations of copper and core losses with vehicle speed and motor output power is necessary to calculate the SRM continuous power rating. These loss variations are estimated by taking into account the operation principles of SRMs and assumed (or known) loss values at only one operating point. Using the obtained expressions, the SRM efficiency contours can be then estimated before the SRM is actually designed and built. This paper shows that the thermal duty of the SRM can be reduced by appropriate choice of the individual loss components in the design process.
Psychological constructs in driving automation: a consensus model and critical comment on construct proliferation

Abstract As automation in vehicles becomes more prevalent, the call for understanding the behaviour of the driver while driving an automated vehicle becomes more salient. Although a variety of driver behaviour models exist, and various psychological constructs have been said to be influenced by automation, an empirically testable psychological model of automated driving has yet to be developed. Building upon Stanton and Young's model of driving automation, this article presents an updated model of interrelated psychological constructs. The proposed model was created based upon a systematic literature search of driving automation papers and a subsequent quantification of the number of reported links between a selected set of psychological constructs. A secondary aim of this article is to reach consensus in the use of psychological constructs regarding driving automation. Henceforth special attention is paid to resolving the issue of construct proliferation.
Observation of heavy ion induced transients in linear circuits

Linear integrated circuits response is susceptible to be disturbed by heavy ion induced transients. The charge deposited by the ion in an amplifier stage can result in a voltage swing which may be amplified again in the following stages of the circuits. Events of this type are thought to be responsible for anomalies in the Earth Sensor of NASA/CNES TOPEX/POSEIDON satellite. First tests have been performed by Koga et al. (1993). In this paper, we present data which confirm Dr. Koga's findings.
Carrier stored trench-gate bipolar transistor (CSTBT)-a novel power device for high voltage application

A new device concept, called the Carrier Stored Trench-Gate Bipolar Transistor (CSTBT) is reported for the first time. The CSTBT forms the n layer under p base between trenches, the n layer stores carriers; as aesult, the carrier distribution of the CSTBT becomes that of the diode. We examined the performance of the CSTBT by simulation and experiment in the case of the blocking voltage of 1700 V, compared to the simple trench IGBT (TIGBT) and the PiN diode. This confirmed the CSTBT is superior to the TIGBT, and the on-state voltage of the CSTBT is almost same as the Vf of the PiN diode. By the fabricated CSTBT, on-state voltage is 1.9 V at 50 A/cm/sup 2/, turn-off time of resistive load switching is about 300 nsec. We realized turn-off current capability of the CSTBT above 250 A/cm/sup 2/.
Integrated transport: from policy to practice

There is a fundamental misunderstanding or disregarding of the basic economic relationship between supply and demand and its role in pricing land and therefore housing and, as a result, who gets the housing. Gruen shows that policy decisions over decades, supported by some landmark court decisions, have forced ever higher land prices as demand has increased with population growth, but government at all levels has not allowed the same ‘free’ movement in supply. Local policies have restricted supply so that supply increases and effective demand are not matched by increases in housing production. The harm this causes ultimately ripples across the whole urban spectrum. Those without ‘effective’ demand have been excluded in too many localities. The harm caused ultimately ripples across the whole urban spectrum. Since 1970, there has been a shift in the determination of land use to public officials who respond to voters, and away from equity owners and developers who respond to the market, i.e. government has taken too much control. In examining this part of the mosaic, Gruen digs deeply and broadly to expose the resultant (bad) effects on low income families, infrastructure requirements, transport and worker location optimal requirements. There is a need for an understanding of urbanization and the need to manage outward urban growth to avoid the ‘bad outcomes’ of urban sprawl although some of the ‘bads’ may seem absurd with little or no substance in many cases. In others, however, Gruen demonstrates how many of these issues can be successfully overcome with appropriate planning and development policy and spending.
Multisensory Wristwatch System for Unobtrusive Physiological and Kinematical Signals Recording

A wearable system for physiological and kinematical signals recording is presented. The device is able to record photoplethysmogram, acceleration, angular velocity, atmospheric pressure, galvanic skin resistance, skin surface temperature and skin humidity. One of the main problems with such data loggers is that they are overly complex and therefore becomes needless. This device is supposed to be worn on the wrist as a simple wrist watch, therefore it is unobtrusive and suitable for long term monitoring. Good functionality and several quantitative parameters of the system was attested by measurements on a healthy volunteer.
Inconsistent Planning and the Allocation of Tasks Over Time

We test the hypothesis of inconsistent planning proposed by Strotz (1955). In the laboratory, participants allocated time between ‘work’ and ‘leisure’ tasks, and were offered a commitment device. Original plans tended to delay leisure, and to involve a moderate degree of spreading between work and leisure tasks. Most participants preferred commitment over flexibility. Although most were denied commitment, few altered their plans. Those that did make changes tended to further postpone leisure. We find limited evidence of discounting or impatience, contrary to the predictions of most theoretical models of inconsistent planning. Instead, our results imply a preference for improving sequences.
