Usefulness of collision warning inter-vehicular system (2010)

This paper studies the contribution and the impact of Inter-Vehicular Communications (IVC) in a vehicles string. We suppose that all, or, a subset of the vehicles are equipped with radio communication devices, enabling communication between them. We evaluate the benefit of the dissemination of warning messages for the reduction of accidents. More precisely, we evaluate and compare the number of vehicles involved in a multi-vehicles crash caused by an accident, with and without the use of IVC. We show that even when a low proportion of vehicles uses IVC, the number of collisions is drastically reduced.

Design of Maximum Efficiency Tracking Control Scheme for Closed-Loop Wireless Power Charging System Employing Series Resonant Tank (2016)

This paper presents a maximum efficiency tracking control scheme for a closed-loop wireless power charging (WPC) system for wireless charging of mobile devices. Generally, wireless charging systems need a precise output voltage and current with the highest possible efficiency. In an open-loop system, output voltage and efficiency depend strongly on the coupling coefficient and load condition. Alternatively, a closed-loop WPC system has a constant output voltage against coupling and load variations. Many studies have been carried out regarding closed-loop systems. However, those previous studies have the drawback of efficiency degradation. In this paper, we propose a maximum efficiency tracking control scheme to achieve the highest possible efficiency. Therefore, the proposed WPC system satisfies both the requirements of a constant output voltage and high efficiency. The proposed control scheme determines the current of the transmitter based on the data received by the receiver via Bluetooth. For validation, the proposed WPC system was implemented at 6.78 MHz using loosely coupled series-series resonant coils, and we verified that the proposed system can track the maximum efficiency while maintaining a constant output voltage.

Orthogonally Substituted Benzimidazole-Carbazole Benzene As Universal Hosts for Phosphorescent Organic Light-Emitting Diodes (2016)

The novel ambipolar hosts of o-CbzBz and o-DiCbzBz contain carbazole and benzimidazole through an ortho-connection. The orthogonal conformations cause the triplet state to be confined at the carbazole units to secure efficient energy transfer. The phosphorescent organic light-emitting diodes (PhOLEDs) show a high current efficiency, power efficiency, and low efficiency roll-off. o-DiCbzBz can be used as a host for sky-blue, green, and orange-red PhOLEDs, giving 57.5, 78.4, and 60.3 cd/A, respectively.
[Transplantation of spermatogonial stem cells and prospects of its application]. (2008)

Spermatogonial stem cells are male germ line stem cells, whose potency of proliferation is indispensable for the permanent production of male germ cells. With the advances in the technology of cryopreservation, in vitro culture and intracytoplasmic sperm injection (ICSI), the transplantation of spermatogonial stem cells is showing a splendid vista of application in basic medical research and clinical practice. This review briefly introduces the genesis and differentiation of spermatogonial stem cells, the current situation of their transplantation and the prospects of its application in medical science.
[Memantine and neurogenic bladder disorders within the bounds of spastic conditions]. (1982)

The action of 1,3-dimethyl-5-aminoadamantane (DMAA, D-145, memantine, Memantine) on neurogenic bladder dysfunction in spastic conditions was investigated. Under memantine treatment micturition was considerably facilitated, and spontaneous, involuntary voiding reduced. Additionally, memantine effected a decrease of residual urine and toned down the vesicular sphincter by simultaneously enhancing detrusor activity. At the same time the patients reported a considerable diminution of spastic hypertonicity and improved mobility of the limb muscles.
Real-Time and In-Situ Detection of Calcium Carbonate Scale in a West Texas Oilfield (2003)

Abstract A novel technique has been developed to detect the onset and increase of calcium carbonate scale deposition from oilfield production fluids. This method utilizes an attenuated total reflectance (ATR) probe, called the scale sensor, to detect scale formation in-situ. Because this method is based on existing technology and requires little supporting equipment, a simple cost-effective monitoring device could be placed in many locations within a production system. This method could provide a system wide, in-situ, real-time response to calcium carbonate scale formation at its earliest stages. As a first step towards evaluating the effectiveness of this new technology, the scale sensor was field tested at a west Texas oilfield. The scale sensor was observed to detect the deposition of calcium carbonate under static and flowing conditions in actual produced fluids. In the static tests, crude oil, suspended solids and other endogenous materials did not affect the scale sensor response. Under flowing conditions, like those found in the production flow lines at the west Texas oilfield, scale sensor response was observed to correlate to the chemical injection rate of both the scale inhibitor and dispersant. Based on the results from the scale sensor, the scale inhibitor injection point will be moved to the wellhead shortly.
Interleukin-6 and verbal memory in recurrent major depressive disorder. (2011)

The results of this study indicated that low performances in IVR and DVR are associated with higher IL-6 levels in women with recurrent MDD. The results of this study suggest the existence of an association between inflammatory imbalance and cognitive impairment in MDD.
Direct Cinemicrography with the Electron Microscope (1967)

Dynamic study of chemical and physical reactions by use of the electron microscope is particularly valuable when combined with cinemicrography, using techniques such as time-lapse photography and continuous magnification changes. Direct use of the imaging electron beam for photographic exposure gives maximum photographic quality, but presents problems of slow speeds of emulsions to electrons, outgassing and embrittlement of film in the microscope vacuum, and static discharge fogging. Several types of 16mm films have been evaluated in microscopy experiments. Techniques for effective ciné recording have been used with special electron microscopy reaction methods for application to nuclear fuel ceramics.
Structure Comparison of High-Frequency Planar Power Integrated Magnetic Circuits (2011)

World power consumption increases from year to year; hence, it is essential to strike new paths in finding effective results for power efficient devices. DC-DC converters are applied in various equipment such as solar photovoltaic installations as well as consumer electronic devices such as LED illumination. To satisfy the need of room saving constructions, planar transformers and integrations of passive parts of the converter are adopted for these purposes. This paper compares two different types of high-frequency planar integrated systems via finite element method and investigates the strengths and weaknesses of both structures.
An improved ZVT PWM boost converter (2002)

This paper proposes an improved ZVT-PWM boost converter. The main switch of the conventional ZVT-PWM converter is always switched at zero voltage. But the auxiliary switch is turned-off with switching loss due to hard switching condition. Therefore, the proposed converter reduces the turn-off switching loss of the auxiliary switch by using an additional circuit. All of the losses for the switches are minimized, and high power density system can be realized.
Tranferencias de contenidos y actividades entre aulas virtuales de asignaturas regladas y de proyectos de innovación educativa: experiencia con un glosario botánico y perspectivas (2015)

Resulta muy interesante que el campus virtual de la Universidad de Malaga (UMA) 
permita traspasar todos los contenidos y actividades (archivos, tareas, wikis, glosarios,…) que 
se crearon en una asignatura a otras y a otros cursos academicos. Esto nos ha permitido 
transferir un glosario creado en una asignatura que se creo en un proyecto de innovacion 
educativa a una asignatura reglada para realizar una experiencia durante el curso 2009-10 con 
un elevado numero de alumnos. Los resultados de esta experiencia han sido muy satisfactorios, 
y hemos podido comprobar que se ha llevado a cabo sin problema y sin conllevar excesiva 
dedicacion para el alumnado y profesorado. Este glosario y metodo de trabajo, asi como muchos 
de los resultados de proyectos de innovacion, se podrian transferir a otras asignaturas. Con un 
protocolo de trabajo bien disenado y probando previamente, bajo el rol de estudiante, paso a 
paso la tarea que se les va a plantear a los alumnos en el campus virtual, el profesor puede 
comprobar si la tarea se llevara a cabo sin problema. Los problemas derivados del 
desconocimiento de algunos detalles tecnicos de la plataforma salen a la luz en estas pruebas 
previas, pueden ser consultados a traves del servicio de ensenanza virtual y laboratorios 
tecnologicos, y es importante conocerlos antes de plantear y disenar el protocolo de trabajo para 
el alumno. 
Los archivos y actividades como wikis y glosarios, etc. resultantes de las experiencias 
piloto en el campus virtual de asignaturas regladas asi como de proyectos de innovacion 
educativa constituyen un excelente metodo y un buen recurso didactico para el aprendizaje en 
diferentes asignaturas regladas y para la elaboracion de los futuros trabajos fin de grado.
Annual Report to the Nation on the Status of Cancer (1973 Through 1998), Featuring Cancers With Recent Increasing Trends (2001)

Overall cancer incidence and death rates continued to decline in the United States. Future progress will require sustained improvements in cancer prevention, screening, and treatment.
Ultra wideband direction finding using digital channelization receiver architecture (2006)

In this paper, UWB direction finding technique using digital channelization receiver architecture Is proposed. The basic idea of this technique is to split the UWB array output into multiple frequency channels and then down-convert each channel into much lower frequency, hence allowing the low sampling rate ADC to be used. Estimation of the DoA of UWB source is achieved by forming a direction finding function using the spectral information from channelizer's output. A thorough performance analysis from simulation results is presented to verify the proposed technique and to investigate the effect of the system's parameters on the performance.
Predicting text entry speed on mobile phones (2000)

We present a model for predicting expert text entry rates for several input methods on a 12-key mobile phone keypad. The model includes a movement component based on Fitts' law and a linguistic component based on digraph, or letter-pair, probabilities. Predictions are provided for one-handed thumb and two-handed index finger input. For the traditional multi-press method or the lesser-used two-key method, predicted expert rates vary from about 21 to 27 words per minute (wpm). The relatively new T9 method works with a disambiguating algorithm and inputs each character with a single key press. Predicted expert rates vary from 41 wpm for one-handed thumb input to 46 wpm for two-handed index finger input. These figures are degraded somewhat depending on the user's strategy in coping with less-than-perfect disambiguation. Analyses of these strategies are presented.
Video-based eye tracking for autostereoscopic displays (2001)

An autostereoscopic display system can provide users the great enjoyment of stereo visualization without the uncomfortable and inconvenient drawbacks of wearing stereo glasses or head-mounted displays. To render stereo video with respect to the user's viewpoints and to accurately project stereo video onto the user's eyes, the left and right eye positions of the user, who is allowed to move around freely, have to be obtained when the user is watching the autostereoscopic display. We present real-time tracking techniques that can efficiently provide the user's eye positions in images. These techniques comprise: 1. face detection by using multiple eigenspaces of various lighting conditions, 2. fast block matching for tracking four motion parameters (X and Y translation, scaling, and rotation) of the user's face, and 3. eye locating in the obtained face region. According to our implementation on a PC with a Pentium III 700 MHz CPU, the frame rate of the eye tracking process can achieve 30 Hz.
Design issues in regulated and unregulated intermediate bus converters (2004)

Recently the use of nonisolated point of load converters (niPOLs) powered from an intermediate bus converter (IBC) has become very popular. This paper looks at the design issues facing the designer of the intermediate bus converter when determining whether the intermediate bus voltage should be regulated or unregulated. It looks at the pros and cons of various regulation methods from a design and also from the perspective of the end customer.
Organic Semiconductor-Polymer Insulator Blends: a Morphological Study of the Guest-Host Interactions (2009)

We suggest a link between film morphology and electrical properties of a crystalline organic semiconductor: polymer insulating blend. TIPS-Pentacene (6,13-bis(triisopropylsilylethynyl) pentacene) [J. Am. Chem. Soc. 123, 9482 (2001)] is formulated with various amorphous and semi-crystalline side chain aromatic low permittivity dielectric polymers. Film structure investigated by AFM microscopy and XPS gives invaluable information regarding film morphology and confirms potential intermolecular interaction. All these morphological observations were linked to the electrical characterisation of organic thin film transistors (OTFTs) and the determination of saturated hole mobility value. When an amorphous binder is used the more dilute the TIPS-pentacene the lower the saturated hole mobility value. When a semi-crystalline binder is used it is possible to massively dilute TIPS-pentacene within the polymer dielectric without loosing either the crystalline structure of the material or the electronic properties. Besides phase segregation, enrichment of the active interface in TIPS-Pentacene is demonstrated. [DOI: 10.1380/ejssnt.2009.455]

The Virtual Sensor Concept : Separating Sensor Software from the Hardware (2020)

Aquatic environmental sensors are expensive which limits the ability to undertake widescale remote monitoring. In most instances, too much logic and functionality are contained within the sensor device itself. This approach is expensive and computationally restrictive. This paper presents a new architectural paradigm for remotely deployed sensors whereby the calibration logic (and other functionality) is separated from the physical sensor hardware. A sensor device is only responsible for taking raw unprocessed sensor readings, which are transmitted back to a central server. All processing occurs on the server where computational capability and sophistication are unbounded. This approach allows for significant flexibility in terms of dynamic calibration adjustments to be applied to sensor data (e.g., in the case of sensor fouling or device decay) and for statistical quality assurance/data production algorithms to be applied. We present an example of how this paradigm can be adopted in this context to a turbidity sensor.
An unknown input observer approach to icing detection for unmanned aerial vehicles with linearized longitudinal motion (2015)

The accretion of ice layers on wings and control surfaces modifies the shape of the aircraft and, consequently, alters performance and controllability of the vehicle. In this paper we propose an Unknown Input Observers framework to design icing diagnosis filters. A case-study is provided as support and validation of theoretical results.
Analysis of a High-Power-Factor Electronic Ballast for High Brightness Light Emitting Diodes (2006)

This paper analyzes the performance of a high-power-factor AC-DC converter for the supply of high-brightness light emitting diodes (HBLEDs). The considered topology is a D <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> one (i.e. a topology that, working in continuous conduction mode, has a voltage conversion ratio that is a function of the duty-cycle squared), working in one of its possible discontinuous modes. No line-frequency energy storage element is used so that the LED current is pulsating at twice the line frequency, with a small high-frequency ripple on top. The impact of such pulsating current supply on LED optical performance and reliability is also evaluated by comparison with standard DC current supply
MCG inverse solution: influence of coil size, grid size, number of coils, and SNR (1988)

Model studies were used to assess quantitatively the influence of gradiometer coil size, number of measurement points, size of measurement grid and signal-to-noise ratio (SNR) on the accuracy of the inverse solution from a magnetocardiogram. The human torso was modeled by an infinite half-space and the inverse solution was calculated by a moving dipole procedure. The most crucial parameter for inverse solution accuracy is the SNR. Up to a coil radius of 4 cm, the increasing SNR balances the loss due to field averaging, and the inverse solution is improved accordingly. A reasonable number of measurement points is about 15; using more points does not improve the inverse solution appreciably. in multichannel systems, grid size is limited by the size of the dewar. It is found that grid size is not crucial in the inverse solution; optimum size is an area of approximately 200-300 cm/sup 2/.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Nanofilament carbon structure (1992)

Matching femoral components with distal femurs in female patients can be difficult. The purpose of this study was to determine the validity of the following hypotheses: (1) Anteroposterior (AP) dimensions do not increase proportionately to medial-lateral (ML) dimensions in men and women. (2) The AP/ML ratio is different in men and women. (3) The AP/ML ratios of femoral implants and the variations in ratios are more in line with data from men than women. Magnetic resonance imaging of the knees of 50 consecutive male patients and 50 consecutive female patients were studied. Both groups had similar age distribution. Anteroposterior and ML dimensions were measured, and AP/ML ratios were obtained and plotted. Inside AP and ML dimensions of 8 popular total knee arthroplasty (TKA) systems produced by 6 manufacturers were obtained. The AP/ML ratio for women was 0.80 (SD=.05), whereas that for men was 0.76 (SD=.03). This study demonstrated a significant difference in distal femur proportions between men and women. Dimensions propagation of femoral components for TKA followed significantly closer to men's distal femur dimensions variation than to that of women.
A thread-aware debugger with an open interface (2000)

While threads have become an accepted and standardized model for expressing concurrency and exploiting parallelism for the shared-memory model, debugging threads is still poorly supported. This paper identifies challenges in debugging threads and offers solutions to them. The contributions of this paper are threefold. First, an open interface for debugging as an extension to thread implementations is proposed. Second, extensions for thread-aware debugging are identified and implemented within the Gnu Debugger to provide additional features beyond the scope of existing debuggers. Third, an active debugging framework is proposed that includes a language-independent protocol to communicate between debugger and application via relational queries ensuring that the enhancements of the debugger are independent of actual thread implementations. Partial or complete implementations of the interface for debugging can be added to thread implementations to work in unison with the enhanced debugger without any modifications to the debugger itself. Sample implementations of the interface for debugging have shown its adequacy for user-level threads, kernel threads and mixed thread implementations while providing extended debugging functionality at improved efficiency and portability at the same time.
