This article introduces a near-optimal bidding algorithm for use in real-time display advertising auctions. These auctions constitute a dominant distribution channel for internet display advertising and a potential funding model for addressable media. The proposed efficient, implementable learning algorithm is proven to rapidly converge to the optimal strategy while achieving zero regret and constituting a competitive equilibrium. This is the first algorithmic solution to the online knapsack problem to offer such theoretical guarantees without assuming a priori knowledge of object values or costs. Furthermore, it meets advertiser requirements by accommodating any valuation metric while satisfying budget constraints. Across a series of 100 simulated and 10 real-world campaigns, the algorithm delivers 98% of the value achievable with perfect foresight and outperforms the best available alternative by 11%. Finally, we show how the algorithm can be augmented to simultaneously estimate impression values and learn the bidding policy. Across a series of simulations, we show that the total regret delivered under this dual objective is less than that from any competing algorithm required only to learn the bidding policy.

Esports is a growing worldwide phenomenon now rivaling traditional sports, with a deep dependence on real-time graphics technology. Despite this, the SIGGRAPH research community has largely ignored it. This panel brings together esports experts in engineering, medicine as well as cognitive and data science to argue that this must change. Like film, esports is an important problem for computer graphics, and could give rise to technologies and techniques benefitting not only esports, but society more broadly. With a series of moderated and audience questions, this panel will sketch the research challenges and potential benefits of esports, while also considering its risks.

Purpose To compare slit-lamp microscopy teaching outcomes with digital camera real-time display and conventional teaching tube in undergraduate education of clinical ophthalmology. Methods Thirty-seven Year 4 medical students were assigned to two groups for slit lamp microscopy teaching with digital camera real-time display (n = 18) and teaching tube (n = 19). The outcome measures included a 5-item questionnaire on their experience and the quality of slit lamp photos taken by the students. Results The overall satisfaction score was significantly higher in the group of digital camera real-time display compared with the group of teaching tube (4.5 ± 0.5 vs. 4.2 ± 0.7, P = .013). The former group also achieved higher quality score of the slit-lamp photography (4.1 ± 0.3 vs. 3.6 ± 0.5, P = .002). Conclusions The digital camera real-time display attachment is more effective in undergraduate ophthalmic education over conventional slit-lamp teaching tube. It is also more favored by students and is thus highly recommended for clinical ophthalmology education.

Objectives: Most of the ultrasound machines include a tool allowing real-time display of the standard value of the biometric measurement being taken. Our hypothesis was that this tool influences the sonographer as measurements are taken, by inducing a normalization, thus a tendency towards the 50th percentile. The objective of this study was to evaluate the impact of a real-time display of the standard value in prenatal ultrasound screening. Methods: We conducted an observational, prospective, controlled and open study including all patients who underwent a prenatal ultrasound scan in the 2nd or 3rd trimester at the University Hospitals in Strasbourg between December 2017 and June 2018. Exclusion criteria were the presence of a fetal morphological abnormality or a karyotypic abnormality. The tool being tested was the real-time display on screen of the gestational age, of which the measurement corresponds to the 50th percentile. The measurements were retrospectively transformed into Z-scores. The main end-point was to compare the distribution of Z-scores between the groups. Results: We included 3551 ultrasound examinations: 696 performed with the tool and 2796 performed without. Fifty-nine scans were excluded due to morphological abnormalities. There was no statistically significant difference between the Z-scores distributions of measurements performed with or without the tool, regardless of the parameter studied. There was also no difference in the detection of pathological measurements: below the 10th percentile or above the 90th percentile. Conclusion: The use of such a tool does not seem to be detrimental to biometric screening, but on the other hand does not seem useful either.

As the most important organ of human circulatory system, the importance of heart is self-evident. At present, electrocardiogram (ECG) detection is widely used in clinic, but it is not conducive to long-term and real-time detection, which is easy to cause burden to patients and may miss the best treatment period. In this paper, a Insentience detection system based on the Seismocardiogram (SCG) signal is designed. The mechanical movement of the heart is measured by the pressure sensor under the object in close contact with the tester. The waveform and the related parameters of detected SCG signal are displayed on portable display device in real time. Experimental results conducted in the real environments shows that by comparing with synchronous extraction of ECG signal, the system can detect the SCG signal real-time and display the signal.

Transparency is an important design consideration for all intelligent autonomous systems. The previous work shows that a real-time visual display of a robot's decisionmaking produces significantly better understanding of that robot's intelligence. We investigate vocalisation of behaviour selection as a possible alternative solution for situations where a visual display of decision-making is either impractical or impossible. In this experiment, we find that vocalisation is associated with a significant improvement in understanding of the robot, comparable with the results obtained using a real-time display. We also find that vocalisation has no significant effect on participants' emotional response, though it may slightly increase positive feelings about the robot. We discuss the relative merits of visual and vocalised transparency mechanisms and suggest possible applications.

Patterned colloidal crystals with stimuli-responsive materials provide sensitive and versatile means for investigating the varying ambiance of heat, light, electricity, magnetism, and stress. However, it remains a challenge to integrate stimuli-responsive materials with colloidal crystals by a simple and efficient method, thus restricting them from being used in general applications. Inspired from chameleons, we present a facile yet high-quality approach for the fabrication of the assembly of colloidal nanoparticles based on the hydrophilic-modified thermosensitive films. Various kinds of integral thermosensitive structural colored (TSSC) films are simply prepared in a high-quality screen on a large scale, with low cost, angle independence, and excellent flexibility. Simply turning on the near-infrared (NIR) laser brings heat to the irradiated region to increase the temperature. Integration of the multi-colored photonic bandgap (PBG) of the thermal-sensitive colloidal crystal and flexible anti-counterfeit labels into the NIR light exciting screens can change the intensity of PBG obviously. This advanced technology not only provides an efficient strategy for the preparation of colloidal crystal but also demonstrates a highly thermosensitive structural colored screen that has great prospect for information storage, anticounterfeiting, and real-time display materials.

We demonstrate optical biopsy of vocal folds to assess its surface and subsurface movement during phonation on ex-vivo calf larynx using parallel OCT (POCT). In this technique, we will enable simultaneous interrogation of multiple locations along the vocal fold, there by eliminating motion-blur artifacts exhibited by the sequential sampling provided by conventional flying-spot OCT. Currently, in voice clinics, laryngologists and speech-language pathologists rely heavily on Video Stroboscopy (VS) coupling with, visual judgments of vocal fold morphology and auditory perceptions of voice quality, to make effective diagnostic, surgical and therapeutic decisions. There is a constant need of an endoscopic imaging tool in voice clinics that can directly capture the three-dimensional (3D) surface motion of the vocal folds in real time as patients phonate. To address the need, we will present a POCT/VS imager that will combine parallel swept source OCT technique with VS to provide a real time display of the vocal folds in all three axial dimensions during phonation. The results will yield cross sections (B-Scans) with ~16 co-linear sampling locations spread over ~5mm on a phonating ex-vivo calf larynx showing fluid periodic cyclic motion of the vocal folds (~A-scan rate) in real time enabled by POCT approach. We will also capture VS images in sync with POCT B-scans validating the real time cross sectional probing of POCT/VS imager.

International audience; This paper presents the last leg of the evolution of the Master Slave (MS) optical coherence tomography (OCT) technology, towards complex master slave (CMS), where phase information is also delivered. We will show how matrix manipulation of signals can lead to real time display. We have demonstrated that this can be executed on central processing units (CPU)s with no need for graphic processing units (GPU)s, yielding simultaneous display of multiple en-face OCT images (C-scans), two cross-section OCT images (B-scans) and an aggregated image, equivalent to a scanning laser ophthalmoscopy (SLO) image when imaging the retina, which is similar to a confocal microscopy image. The same protocol can obviously be applied employing GPUs when using faster acquisition engines, such as multi MHz swept optical sources.

A good contrast enhancement (CE) algorithm should not only have good performance but also be computationally efficient for real time display. In this paper, we propose a novel efficient CE algorithm, which applies adaptive thresholding based on the slope obtained from a sorted histogram of the input image. The algorithm allows to control levels of perceived contrast. Compared with state-of-the-art CE algorithms, the proposed algorithm shows highly competitive performance with real-time speed.

We investigated the use of optical coherence tomography (OCT) to measure several materials immersed in optical adhesives. The effects of variations in the concentration, physical characteristics, and thickness of the materials were studied, and these parameters were found to significantly affect the OCT measurement. The materials were selected for their distinct spectral properties in the infrared region. To ensure reliability, we acquired images using a scanning electron microscope after performing the semiconductor production process. We verified the feasibility of the application of OCT for defect inspection and product verification of touch-screen panels.

There are many reports on position-related complications in neurosurgical literature but so far, continuous quantification of the patient's position during the surgery has not been reported. This study aims to explore the utility of a new surgical table system and its software in displaying the patient's body positions during surgery on real-time basis. More than 200 neurosurgical cases were monitored for their positions intra-operatively. The position was digitally recorded and could be seen by all the members in the operating team. It also displayed the three-dimensional relationship between the head and the heart positions. No position-related complications were observed during the study. The system was able to serve as an excellent indicator for monitoring the patient's position. The recordings were analyzed and even used to reproduce or improve the position in the subsequent operations. The novel technique of monitoring the position of the head and the heart of the patients and the operating table planes are considered to be useful during delicate neurosurgical procedures thereby, preventing inadvertent procedural errors. This can be used to quantify various surgical positions in the future and define safety measures accordingly.

Despite evidence that monitoring domestic electricity usage can reduce consumption, there is currently little information on what factors motivate people to monitor their consumption. The present research used an augmented version of the theory of planned behavior as a framework for understanding householders' intentions. Participants (N = 346) completed a questionnaire measuring their beliefs about electricity use and monitoring consumption, their environmental behavior, and concern about climate change. Regression revealed that the primary predictors of intentions to monitor consumption were perceived behavioral control, attitudes toward monitoring, past behavior, descriptive, and subjective norms. In addition, we developed a modified home electricity monitor that legged when participants looked at their consumption. A subset of participants (n = 38) were given a monitor for three months. Participants looked at the monitor relatively frequently during the first week but usage rapidly declined. There was, however, some evidence that participants found the monitor beneficial.

This paper presents details of the design and implementation of a system for measuring of thermally stimulated current (TSC) and transient photocurrent (Iph), developed using the Virtual Instrumentation concept. For that we have used National Instrument hardware and the LabView® package as software. The system is controlled by a virtual instrument (VI) which includes facilities to perform measurements of photocurrent keeping the temperature of the sample and the pressure of the chamber of measurement controlled as well as real time display of the Iph vs t and TSC vs T curves. The system was tested by performing transient photocurrent and TSC measurements on CH3NH3PbI3 thin films that are generally used as absorbent layer of solar cells. This type of characterization is very useful to get information of the trapping and recombination processes that affect the transport properties of the devices. Este trabajo presenta los detalles del diseño y la implementación de un sistema de medición de corriente termicamente estimulada (TSC, por sus siglas en inglés) y fotocorriente transitoria (Iph), desarrollado a partir del concepto de Instrumentación Virtual. Para esto, se ha utilizado el hardware de National Instrument y el paquete LabView® como software. El sistema está controlado por un instrumento virtual (VI, por sus siglas en inglés) que incluye instalaciones para realizar mediciones de fotocorriente manteniendo la temperatura de la muestra y la presión de la cámara de medida controlada, así como una visualización en tiempo real de las curvas Iph vs t y TSC vs T . El sistema se probó mediante la realización de fotocorrientes transitorias y mediciones de TSC en películas delgadas CH3NH3PbI3 que se utilizan, generalmente, como capa absorbente de células solares. Este tipo de caracterización es muy útil para obtener información de los procesos de captura y recombinación que afectan las propiedades de transporte de los dispositivos.

Scanning Ion Conductance Microscopy (SICM) is one kind of Scanning Probe Microscopies (SPMs), and it can be used in mapping topographical features of sample at high - resolution with free contact by measuring the ion current of ultra-micropipette. SICM is widely used in imaging soft samples for many distinct merits, such as high resolution imaging, simple preparation of probe and no harm to sample surface. However, it is undeniable that the scanning speed of SICM is much slower than other SPMs, especially for large scale and high resolution imaging. Fortunately, compressive sensing (CS), which breaks through the Shannon's sampling theorem for dramatically reducing sample rate, could improve scanning speed tremendously, but it still costs much time in image reconstruction. Therefore block compressive sensing was applied to SICM imaging for reducing the reconstruction time of sparse signals, and it has an anther further and unique application that it can achieve the function of image real-time display. In this paper, a new method of dividing blocks and a new matrix arithmetic operation was proposed to build the block compressive sensing model, and several experiments was taken to verified the superiority of block compressive sensing in reducing imaging time and image real-time display used SICM.

At last, this paper also has applied USB - CAN set instruments to implement the communications and the connection between battery management system and PC communications.

Wearing a motorcycle helmet reduces accident fatalities by almost one-third (29 percent). Presently, head injury is a leading cause of death in motorcycle crashes. Riders who don't wear helmets and who experience a crash are 40 percent more likely to sustain a fatal head injury. The proposed system includes a helmet controlled safety system wherein the motorcycle ignition is enabled only when the helmet is put on and stand is removed. This system also incorporates other features like Global Positioning System; automatic head light control and Real time display. Such features serve as the rider aids. The GPS tracker used in our system forwards the co-ordinates that indicate the current location of the motorcycle in case it is stolen or it has to be tracked.

Beginning level Mandarin learners with different L1 backgrounds received six hours of Mandarin tone training using phrases and sentences produced by multiple native Mandarin speakers. Using Kay Elementric’s Sona Speech II software with real time display of pitch contours along with speech output on a PC computer, the trainees had both auditory and visual input when they recorded and compared their own productions with the training stimuli during the training. The trainees’ productions of Mandarin tones were judged by native Mandarin listeners to be significantly better at post test than at pretest. Such improvement was not matched by a control group that received the same classroom instruction but did not take the training. The trainees also reported very positive experience with the training. The findings suggest that the training is effective for learning Mandarin tones in a larger linguistic context beyond isolated syllables.

The evaluation of a new occupational Dose Aware System (DAS) showing staff radiation doses in real time has been carried out in several angiography rooms in our hospital. The system uses electronic solid-state detectors with high-capacity memory storage. Every second, it archives the dose and dose rate measured and is wirelessly linked to a base-station screen mounted close to the diagnostic monitors. An easy transfer of the values to a data sheet permits further analysis of the scatter dose profile measured during the procedure, compares it with patient doses, and seeks to find the most effective actions to reduce operator exposure to radiation.The cumulative occupational doses measured per procedure (shoulder-over lead apron) ranged from 0.6 to 350 μSv when the ceiling-suspended screen was used, and DSA (Digital Subtraction Acquisition) runs were acquired while the personnel left the angiography room. When the suspended screen was not used and radiologists remained inside the angiography room during DSA acquisitions, the dose rates registered at the operator's position reached up to 1-5 mSv/h during fluoroscopy and 12-235 mSv/h during DSA acquisitions. In such case, the cumulative scatter dose could be more than 3 mSv per procedure.Real-time display of doses to staff members warns interventionists whenever the scatter dose rates are too high or the radiation protection tools are not being properly used, providing an opportunity to improve personal protection accordingly.

The use of intraoperative neurophysiological monitoring (IONM) in neurosurgery has improved patient safety and outcomes. However, a pitfall in the use of IONM remains unsolved. Currently, there is no feasible way for surgeons to interpret IONM waves themselves during operations. Instead, they have to rely on verbal feedback from a neurophysiologist. This method is prone to communication failures, which can lead to delayed or false interpretation of the data. Direct visualization of IONM waves is a way to alleviate this problem and make IONM more effective. Microscope-integrated IONM (MI-IONM) was used in 163 cranial and spinal cases. We evaluated the feasibility, system stability and how well the system integrated into the surgical workflow. We used an IONM system that was connected to a surgical microscope. All IONM modalities used at our institution could be visualized as required, superimposed on the surgical field in the eyepiece of the microscope without obstructing the surgeon’s field of vision. Use of MI-IONM was safe and reliable. It furthermore provided valuable intraoperative information. The system merely required a short learning curve. Only minor system problems without impact on surgical workflow occurred. MI-IONM proved to be especially useful in surgical cases where careful monitoring of nerve function is required, e.g., cerebellopontine angle surgery. Here, direct assessment of surgical action and IONM wave change was provided to the surgeon, if necessary (on-off control). MI-IONM is a useful extension of conventional IONM that provides optional real-time functional information to the surgeon on demand.

Background: The complicated anatomy of orbit and the wide spectrum of pathological conditions present a formidable challenge for early diagnosis, which is critical for management. Ultrasonography provides a detailed cross sectional anatomy of the entire globe with excellent topographic visualization and real time display of the moving organ. Objectives of the study: To evaluate the efficacy of high frequency Ultrasound in localization of orbital diseases and to characterize various orbital pathologies sonologically. Materials and Methods: Hundred eyes of 85 patients were examined with ultrasound using linear high frequency probe (5 to 17 MHz) of PHILPS IU22 ultrasound system. Sonological diagnosis was made based on location, acoustic characteristics, kinetic properties and Doppler flow dynamics. Final diagnosis was made based on clinical & laboratory findings/higher crosssectional imaging/surgery & histopathology (as applicable). Diagnostic accuracy of ultrasonography was evaluated and compared with final diagnosis. Results: The distinction between ocular and extraocular pathologies was made in 100% of cases. The overall sensitivity, specificity, NPV and accuracy of ultrasonography were 94.2%, 98.8%, 92.2% & 94.9% respectively for diagnosis of ocular pathologies and 94.2%, 99.2%, 95.9% & 95.2% respectively for extra ocular pathologies. Conclusion: Ultrasonography is a readily available, simple, cost effective, non ionizing and non invasive modality with overall high diagnostic accuracy in localising and characterising orbital pathologies. It has higher spatial and temporal resolution compared to CT/MRI. However, CT/MRI may be indicated in certain cases for the evaluation of calcifications, bony involvement, extension to adjacent structures and intracranial extension.

Three-dimension electronic chart display information system (ECDIS) is one of the new developing directions of electronic navigation chart, and its real-time quality is one of the important requirements. In this paper the algorithm of simplifying triangle surface using edge contraction, which can ensure the real-time display of objects in seabed environment, was put forward. The optimum contraction point was determined by the Lagrange matrix, so that the algorithm ensures that the contraction point locates on the original model, meanwhile meets the demands of least deviation. This algorithm can improve the plotting speed, and preserve the boundary character by using the fewer triangles to simulate objects.

Introduction The number of fluoroscopically guided invasive diagnostic and interventional urology procedures is increasing during the last few years. This leads to higher staff doses in comparison with other radiology procedures. Purpose The aim of this study is to evaluate staff doses in fluoroscopically guided invasive diagnostic and interventional urology procedures. All the data were collected in Emergency Hospital “N. I. Pirogov” on an old fluorography unit with X-ray tube over the table. Materials and methods Staff doses for intravenous pyelogram (IVP), percutaneous nephrostomy (PN) and ureteral “double-J” stenting were estimated with the system RaySafe i2 . It contains four dosimeters, with a wireless connection to a real time display. The dosimeters were worn on the unprotected upper part of the body and measured the personal dose equivalent H p (10). In order to evaluate the dose of the eye lense in personal dose equivalent H p (3) two methods were used: thermoluminescent dosimetry and Monte Carlo simulations. Results The highest staff dose for PN and “double-J” is received by the urologist (116.7 μSv and 42.6 μSv, respectively), while for the IVP the radiographer has the highest exposure (20.7 μSv). First results for the dose of the eye lense show values of 1.63 mSv for left eye and 5.67 mSv for right eye. Each member of the medical staff was on a different position in respect to the X-ray tube and the patient which is the main reason for the differences in the staff doses. Conclusion The variations in the mean staff doses are mostly due to the interventions themselves, their complexity and the individual treatment of every patient. RaySafe i2 is very useful and educational system. It can be a helpful tool for decreasing radiation exposure to medical staff. Acknowledgement The authors would like to thank RaySafe for the kindly submitted for temporary use i2 system.

Rendering and animating in real-time a multitude of articulated characters presents a real challenge, and few hardware systems are up to the task. Up to now, little research has been conducted to tackle the issue of real-time rendering of numerous virtual humans. This paper presents a hardware-independent technique that improves the display rate of animated characters by acting on the sole geometric and rendering information. We first review the acceleration techniques traditionally in use in computer graphics and highlight their suitability to articulated characters. We then show how impostors can be used to render virtual humans. We introduce concrete case studies that demonstrate the effectiveness of our approach. Finally, we tackle the visibility issue.

A novel, portable electrochemical sensing gadget has been developed to analyze the level of uric acid in human urine. It uses gold nanoparticles embedded, chemically modified carbon paste electrode. The uric acid level is identified as the main marker in a majority of the diseases, such as urolithiasis, gout, myeloma, and so on. The main objective of the present effort was to study the level of uric acid accurately in minimum time. For this, we developed an instant, real-time monitoring kit to give accurate and fast data on the level of uric acid in a real sample. The initial work focused on developing chemically modified gold nanoparticles embedded carbon paste electrode, while the later part was aimed at converting the effort into a full detecting kit with a real time display unit to display levels of uric acid and to give a suitable indication. Since the detection kit requires neither sophisticated lab nor specific conditions to work, it is portable. This can be used as a uric acid screening device even in rural health centers. This paper can help the medical practitioners as well as the lab technicians to analyze samples quickly and give better support to the patients.

We present the design and first field trial results of the all-day all-weather INVIS Integrated Night Vision surveillance and observation System. The INVIS augments a dynamic three-band false-color nightvision image with synthetic 3D imagery in a real-time display. The night vision sensor suite consists of three cameras, respectively sensitive in the visual (400-700 nm), the near-infrared (700-1000 nm) and the longwave infrared (8-14 μm) bands of the electromagnetic spectrum. The optical axes of the three cameras are aligned. Image quality of the fused sensor signals can be enhanced in real-time through Dynamic Noise Reduction, Superresolution, and Local Adaptive Contrast Enhancement. The quality of the longwave infrared image can be enhanced through Scene-Based Non-Uniformity Correction (SBNUC), intelligent clustering and thresholding. The visual and near-infrared signals are used to represent the resulting multiband nightvision image in realistic daytime colors, using the Color-the-Night color remapping principle. Color remapping can also be deployed to enhance the visibility of thermal targets that are camouflaged in the visual and near-infrared range of the spectrum. The dynamic false-color nighttime images can be augmented with corresponding synthetic 3D scene views, generated in real-time using a geometric 3D scene model in combination with position and orientation information supplied by the GPS and inertial sensors of the INVIS system. © 2010 SPIE.
