    While more accurate and reliable than ever, the trustworthiness of biometric verification systems is compromised by the emergence of spoofing attacks. Responding to this threat, numerous research publications address isolated spoofing detection, resulting in efficient counter-measures for many biometric modes. However, an important, but often overlooked issue regards their engagement into a verification task and how to measure their impact on the verification systems themselves. A novel evalu...

  3. Analysis of the Symmetric and Anti-Symmetric Modes in Spoof-Insulator-Spoof Waveguides

    Spoof-insulator-spoof (SIS) waveguides can support propagating modes of spoof surface plasmon polaritons (SPPs). Here, the symmetry properties and dependence of dimensionality of the spoof SPPs in SIS waveguides are studied both numerically and experimentally. The dispersions of spoof SPPs in two-dimensional (2D) waveguides are distinct from those in 3D waveguides. A cut-off frequency appears at k = 0 for the symmetric mode in the 2D structure. It is found that, from the 2D to 3D case, the dimensional dependence of the spoof SPPs in SIS waveguides is similar to the "real" SPPs in metal-insulator-metal (MIM) structures. However, their asymptotic behaviors for large k are quite different since the coupling in the direction of thickness are different for the spoof SPPs and "real" SPPs. Our results can be useful in both the physics and applications of the surface modes in the microwave regime.

    2017-10-01

    Electronically controllable multipolar spoof localized surface plasmons (LSPs) are experimentally demonstrated in the microwave frequencies. It has been shown that half integer order LSPs modes exist on the corrugated ring loaded with a slit, which actually arise from the Fabry-Perot-like resonances. By mounting active components across the slit in the corrugated rings, electronic switchability and tunability of spoof LSPs modes have been accomplished. Both simulated and measured results demonstrate efficient dynamic control of the spoof LSPs. These elements may form the basis of highly integrated programmable plasmonic circuits in microwave and terahertz regimes.

  8. GNSS Spoofing Network Monitoring Based on Differential Pseudorange.

    Science.gov (United States)

    Zhang, Zhenjun; Zhan, Xingqun

    2016-10-23

    Spoofing is becoming a serious threat to various Global Navigation Satellite System (GNSS) applications, especially for those that require high reliability and security such as power grid synchronization and applications related to first responders and aviation safety. Most current works on anti-spoofing focus on spoofing detection from the individual receiver side, which identifies spoofing when it is under an attack. This paper proposes a novel spoofing network monitoring (SNM) mechanism aiming to reveal the presence of spoofing within an area. Consisting of several receivers and one central processing component, it keeps detecting spoofing even when the network is not attacked. The mechanism is based on the different time difference of arrival (TDOA) properties between spoofing and authentic signals. Normally, TDOAs of spoofing signals from a common spoofer are identical while those of authentic signals from diverse directions are dispersed. The TDOA is measured as the differential pseudorange to carrier frequency ratio (DPF). In a spoofing case, the DPFs include those of both authentic and spoofing signals, among which the DPFs of authentic are dispersed while those of spoofing are almost overlapped. An algorithm is proposed to search for the DPFs that are within a pre-defined small range, and an alarm will be raised if several DPFs are found within such range. The proposed SNM methodology is validated by simulations and a partial field trial. Results show 99.99% detection and 0.01% false alarm probabilities are achieved. The SNM has the potential to be adopted in various applications such as (1) alerting dedicated users when spoofing is occurring, which could significantly shorten the receiver side spoofing cost; (2) in combination with GNSS performance monitoring systems, such as the Continuous Operating Reference System (CORS) and GNSS Availability, Accuracy, Reliability anD Integrity Assessment for Timing and Navigation (GAARDIAN) System, to provide more

  9. GNSS Spoofing Detection and Mitigation Based on Maximum Likelihood Estimation.

    Spoofing attacks are threatening the global navigation satellite system (GNSS). The maximum likelihood estimation (MLE)-based positioning technique is a direct positioning method originally developed for multipath rejection and weak signal processing. We find this method also has a potential ability for GNSS anti-spoofing since a spoofing attack that misleads the positioning and timing result will cause distortion to the MLE cost function. Based on the method, an estimation-cancellation approach is presented to detect spoofing attacks and recover the navigation solution. A statistic is derived for spoofing detection with the principle of the generalized likelihood ratio test (GLRT). Then, the MLE cost function is decomposed to further validate whether the navigation solution obtained by MLE-based positioning is formed by consistent signals. Both formulae and simulations are provided to evaluate the anti-spoofing performance. Experiments with recordings in real GNSS spoofing scenarios are also performed to validate the practicability of the approach. Results show that the method works even when the code phase differences between the spoofing and authentic signals are much less than one code chip, which can improve the availability of GNSS service greatly under spoofing attacks.

    Automatic speaker verification (ASV) systems are vulnerable to spoofing attacks using speech generated by voice conversion and speech synthesis techniques. Commonly, a countermeasure (CM) system is integrated with an ASV system for improved protection against spoofing attacks. But integration...... of the two systems is challenging and often leads to increased false rejection rates. Furthermore, the performance of CM severely degrades if in-domain development data are unavailable. In this study, therefore, we propose a solution that uses two separate background models – one from human speech...

    As the plethora of approaches to biometrics and their deployment continues to grow, so too does the need to combat the techniques used to subvert the aim of such biometric systems. Presenting the first definitive study of the subject, this Handbook of Biometric Anti-Spoofing reviews the state of the art in covert attacks against biometric systems, and in deriving countermeasures to these attacks. Across a range of common biometrics, including face, iris, fingerprint, speaker and gait, the book describes spoofing methods and examines the vulnerabilities of biometric systems to these attacks.

  12. Possibility of spoof attack against robustness of multibiometric authentication systems

    Hariri, Mahdi; Shokouhi, Shahriar Baradaran

    2011-07-01

    Multibiometric systems have been recently developed in order to overcome some weaknesses of single biometric authentication systems, but security of these systems against spoofing has not received enough attention. In this paper, we propose a novel practical method for simulation of possibilities of spoof attacks against a biometric authentication system. Using this method, we model matching scores from standard to completely spoofed genuine samples. Sum, product, and Bayes fusion rules are applied for score level combination. The security of multimodal authentication systems are examined and compared with the single systems against various spoof possibilities. However, vulnerability of fused systems is considerably increased against spoofing, but their robustness is generally higher than single matcher systems. In this paper we show that robustness of a combined system is not always higher than a single system against spoof attack. We propose empirical methods for upgrading the security of multibiometric systems, which contain how to organize and select biometric traits and matchers against various possibilities of spoof attack. These methods provide considerable robustness and present an appropriate reason for using combined systems against spoof attacks.

    2013-09-01

    Traffic sensing systems rely more and more on user generated (insecure) data, which can pose a security risk whenever the data is used for traffic flow control. In this article, we propose a new formulation for detecting malicious data injection in traffic flow monitoring systems by using the underlying traffic flow model. The state of traffic is modeled by the Lighthill- Whitham-Richards traffic flow model, which is a first order scalar conservation law with concave flux function. Given a set of traffic flow data generated by multiple sensors of different types, we show that the constraints resulting from this partial differential equation are mixed integer linear inequalities for a specific decision variable. We use this fact to pose the problem of detecting spoofing cyber attacks in probe-based traffic flow information systems as mixed integer linear feasibility problem. The resulting framework can be used to detect spoofing attacks in real time, or to evaluate the worst-case effects of an attack offliine. A numerical implementation is performed on a cyber attack scenario involving experimental data from the Mobile Century experiment and the Mobile Millennium system currently operational in Northern California. © American Institute of Mathematical Sciences.

    Gait is a relatively biometric modality which has a precious advantage over other modalities, such as iris and voice, in that it can be easily captured from a distance. Although it has recently become a topic of great interest in biometric research, there has been little investigation into gait spoofing attacks where a person tries to imitate the clothing or walking style of someone else. We recently analyzed for the first time the effects of spoofing attacks on silhouette-based gait biometric systems and showed that it was indeed possible to spoof gait biometric systems by clothing impersonation and the deliberate selection of a target that has a similar build to the attacker. To gain deeper insight into the performance of current gait biometric systems under spoofing attacks, we provide a thorough investigation on how clothing can be used to spoof a target and evaluate the performance of two state-of-the-art recognition methods on a gait spoofing database recorded at the University of Southampton. Furthermore, we describe and evaluate an initial solution coping with gait spoofing attacks. The obtained results are very promising and point out interesting findings which can be used for future investigations.

    Full Text Available A threat to GNSS receivers is posed by a spoofing transmitter that emulates authentic signals but with randomized code phase and Doppler values over a small range. Such spoofing signals can result in large navigational solution errors that are passed onto the unsuspecting user with potentially dire consequences. An effective spoofing detection technique is developed in this paper, based on signal power measurements and that can be readily applied to present consumer grade GNSS receivers with minimal firmware changes. An extensive statistical analysis is carried out based on formulating a multihypothesis detection problem. Expressions are developed to devise a set of thresholds required for signal detection and identification. The detection processing methods developed are further manipulated to exploit incidental antenna motion arising from user interaction with a GNSS handheld receiver to further enhance the detection performance of the proposed algorithm. The statistical analysis supports the effectiveness of the proposed spoofing detection technique under various multipath conditions.

    Full Text Available The spoofing attack is one of the security threats of systems depending on the Global Navigation Satellite System (GNSS. There have been many GNSS spoofing detection methods, and each of them focuses on a characteristic of the GNSS signal or a measurement that the receiver has obtained. The method based on a single detector is insufficient against spoofing attacks in some scenarios. How to fuse multiple detections together is a problem that concerns the performance of GNSS anti-spoofing. Scholars have put forward a model to fuse different detection results based on the Dempster-Shafer theory (DST of evidence combination. However, there are some problems in the application. The main challenge is the valuation of the belief function, which is a key issue in DST. This paper proposes a practical method of detections’ fusion based on an approach to assign the belief function for spoofing detections. The frame of discernment is simplified, and the hard decision of hypothesis testing is replaced by the soft decision; then, the belief functions for some detections can be evaluated. The method is discussed in detail, and a performance evaluation is provided, as well. Detections’ fusion reduces false alarms of detection and makes the result more reliable.

    Spoof attack by replicating biometric traits represents a real threat to an automatic biometric verification/ authentication system. This is because the system, originally designed to distinguish between genuine users from impostors, simply cannot distinguish between a replicated biometric sample (replica) from a live sample. An effective solution is to obtain some measures that can indicate whether or not a biometric trait has been tempered with, e.g., liveness detection measures. These measures are referred to as evidence of spoofing or anti-spoofing measures. In order to make the final accept/rejection decision, a straightforward solution to define two thresholds: one for the anti-spoofing measure, and another for the verification score. We compared two variants of a method that relies on applying two thresholds - one to the verification (matching) score and another to the anti-spoofing measure. Our experiments carried out using a signature database as well as by simulation show that both the brute-force and its probabilistic variant turn out to be optimal under different operating conditions.

    In this paper, we introduce a new scheme to construct the band-pass tunable filter based on the band-pass reconfigurable spoof surface plasmon polaritons (SPPs), whose cut-off frequencies at both sides of the passband can be tuned through changing the direct current (DC) bias of varactors. Compared to traditional technology (e.g. microstrip filters), the spoof SPP structure can provide more tight field confinement and more significant field enhancement, which is extremely valuable for many system applications. In order to achieve this scheme, we proposed a specially designed SPP filter integrated with varactors and DC bias feeding structure to support the spoof SPP passband reconfiguration. Furthermore, the full-wave simulated result verifies the outstanding performance on both efficiency and reconfiguration, which has the potential to be widely used in advanced intelligent systems.

To verify our results, the computed band diagram of the structure has been compared with the one obtained using the body-of-revolution finite-difference time-domain method. The obtained spoof surface plasmon modes have been shown to be highly localized and slowly propagating. Variations of the obtained modal frequencies and mode profiles as a function of the depth and width of the grooves have also been investigated.

  9. Face Spoofing Detection Through Visual Codebooks of Spectral Temporal Cubes.

    Pinto, Allan; Pedrini, Helio; Schwartz, William Robson; Rocha, Anderson

    2015-12-01

    Despite important recent advances, the vulnerability of biometric systems to spoofing attacks is still an open problem. Spoof attacks occur when impostor users present synthetic biometric samples of a valid user to the biometric system seeking to deceive it. Considering the case of face biometrics, a spoofing attack consists in presenting a fake sample (e.g., photograph, digital video, or even a 3D mask) to the acquisition sensor with the facial information of a valid user. In this paper, we introduce a low cost and software-based method for detecting spoofing attempts in face recognition systems. Our hypothesis is that during acquisition, there will be inevitable artifacts left behind in the recaptured biometric samples allowing us to create a discriminative signature of the video generated by the biometric sensor. To characterize these artifacts, we extract time-spectral feature descriptors from the video, which can be understood as a low-level feature descriptor that gathers temporal and spectral information across the biometric sample and use the visual codebook concept to find mid-level feature descriptors computed from the low-level ones. Such descriptors are more robust for detecting several kinds of attacks than the low-level ones. The experimental results show the effectiveness of the proposed method for detecting different types of attacks in a variety of scenarios and data sets, including photos, videos, and 3D masks.

  10. Face Spoof Attack Recognition Using Discriminative Image Patches

    2016-01-01

    Full Text Available Face recognition systems are now being used in many applications such as border crossings, banks, and mobile payments. The wide scale deployment of facial recognition systems has attracted intensive attention to the reliability of face biometrics against spoof attacks, where a photo, a video, or a 3D mask of a genuine user’s face can be used to gain illegitimate access to facilities or services. Though several face antispoofing or liveness detection methods (which determine at the time of capture whether a face is live or spoof have been proposed, the issue is still unsolved due to difficulty in finding discriminative and computationally inexpensive features and methods for spoof attacks. In addition, existing techniques use whole face image or complete video for liveness detection. However, often certain face regions (video frames are redundant or correspond to the clutter in the image (video, thus leading generally to low performances. Therefore, we propose seven novel methods to find discriminative image patches, which we define as regions that are salient, instrumental, and class-specific. Four well-known classifiers, namely, support vector machine (SVM, Naive-Bayes, Quadratic Discriminant Analysis (QDA, and Ensemble, are then used to distinguish between genuine and spoof faces using a voting based scheme. Experimental analysis on two publicly available databases (Idiap REPLAY-ATTACK and CASIA-FASD shows promising results compared to existing works.

While recent work has shown the potential to develop countermeasures capable of detecting spoofed speech signals, existing solutions typically function well only for specific attacks on which they are optimised.

  12. Terahertz spoof surface-plasmon-polariton subwavelength waveguide

    KAUST Repository

    2017-12-11

    Surface plasmon polaritons (SPPs) with the features of subwavelength confinement and strong enhancements have sparked enormous interest. However, in the terahertz regime, due to the perfect conductivities of most metals, it is hard to realize the strong confinement of SPPs, even though the propagation loss could be sufficiently low. One main approach to circumvent this problem is to exploit spoof SPPs, which are expected to exhibit useful subwavelength confinement and relative low propagation loss at terahertz frequencies. Here we report the design, fabrication, and characterization of terahertz spoof SPP waveguides based on corrugated metal surfaces. The various waveguide components, including a straight waveguide, an S-bend waveguide, a Y-splitter, and a directional coupler, were experimentally demonstrated using scanning near-field terahertz microscopy. The proposed waveguide indeed enables propagation, bending, splitting, and coupling of terahertz SPPs and thus paves a new way for the development of flexible and compact plasmonic circuits operating at terahertz frequencies.

    With the development of speech synthesis techniques, automatic speaker verification systems face the serious challenge of spoofing attack. In order to improve the reliability of speaker verification systems, we develop a new filter bank-based cepstral feature, deep neural network (DNN) filter bank...... cepstral coefficients, to distinguish between natural and spoofed speech.

By adding restrictions on the training rules, the learned weight matrix of FBNN is band limited...... and sorted by frequency, similar to the normal filter bank. Unlike the manually designed filter bank, the learned filter bank has different filter shapes in different channels, which can capture the differences between natural and synthetic speech more effectively.

    The challenge for the facial based security system is how to detect facial image falsification such as facial image spoofing. Spoofing occurs when someone try to pretend as a registered user to obtain illegal access and gain advantage from the protected system. This research implements facial image spoofing detection method by analyzing image texture. The proposed method for texture analysis combines the Local Binary Pattern (LBP) and Gray Level Co-occurrence Matrix (GLCM) method. The experimental results show that spoofing detection using LBP and GLCM combination achieves high detection rate compared to that of using only LBP feature or GLCM feature.

  17. A Smart Spoofing Face Detector by Display Features Analysis

    2016-07-01

    Full Text Available In this paper, a smart face liveness detector is proposed to prevent the biometric system from being “deceived” by the video or picture of a valid user that the counterfeiter took with a high definition handheld device (e.g., iPad with retina display. By analyzing the characteristics of the display platform and using an expert decision-making core, we can effectively detect whether a spoofing action comes from a fake face displayed in the high definition display by verifying the chromaticity regions in the captured face. That is, a live or spoof face can be distinguished precisely by the designed optical image sensor. To sum up, by the proposed method/system, a normal optical image sensor can be upgraded to a powerful version to detect the spoofing actions. The experimental results prove that the proposed detection system can achieve very high detection rate compared to the existing methods and thus be practical to implement directly in the authentication systems.

    Brian Lloyd

    2013-08-01

    Full Text Available Richard Rorty was a strong contextualist in his approach to philosophical and political ideas, yet his own most characteristic arguments are typically evaluated without much reference to the historical circumstances that provoked them. A key participant in the post-1980 revival of pragmatism within North American and European intellectual circles, Rorty reaffirmed the strong connections between American pragmatism and German idealism. This move placed him at odds with scholars who forged the unity of pragmatism—united John Dewey and William James—under the banner of radical empiricism. Those engaged most enthusiastically in celebrating Rorty’s achievements, in short, defend a conception of pragmatism that Rorty sharply criticized and ideas about the history of philosophy that he did not share. His distinctive intellectual agenda is best appreciated after setting it in the context of the history of the American Left and, more specifically, the reckoning with the tumultuous 1960s that animates so many ongoing debates—inside and outside the academy—about cultural and political affairs.

    Full Text Available We present a highly sensitive microfluidic sensing technique for the terahertz (THz region of the electromagnetic spectrum based on spoof surface plasmon polaritons (SPPs. By integrating a microfluidic channel in a spoof SPP waveguide, we take advantage of these highly confined electromagnetic modes to create a platform for dielectric sensing of liquids. Our design consists of a domino waveguide, that is, a series of periodically arranged rectangular metal blocks on top of a metal surface that supports the propagation of spoof SPPs. Through numerical simulations, we demonstrate that the transmission of spoof SPPs along the waveguide is extremely sensitive to the refractive index of a liquid flowing through a microfluidic channel crossing the waveguide to give an interaction volume on the nanoliter scale. Furthermore, by taking advantage of the insensitivity of the domino waveguide’s fundamental spoof SPP mode to the lateral width of the metal blocks, we design a tapered waveguide able to achieve further confinement of the electromagnetic field. Using this approach, we demonstrate the highly sensitive detection of individual subwavelength micro-particles flowing in the liquid. These results are promising for the creation of spoof SPP based THz lab-on-a-chip microfluidic devices that are suitable for the analysis of biological liquids such as proteins and circulating tumour cells in buffer solution.

  7. DETECTION AND LOCALIZATION OF MULTIPLE SPOOFING ATTACKERS FOR MOBILE WIRELESS NETWORKS

    Directory of Open Access Journals (Sweden)

    R. Maivizhi

    2015-06-01

    Full Text Available The openness nature of wireless networks allows adversaries to easily launch variety of spoofing attacks and causes havoc in network performance. Recent approaches used Received Signal Strength (RSS traces, which only detect spoofing attacks in mobile wireless networks. However, it is not always desirable to use these methods as RSS values fluctuate significantly over time due to distance, noise and interference. In this paper, we discusses a novel approach, Mobile spOofing attack DEtection and Localization in WIireless Networks (MODELWIN system, which exploits location information about nodes to detect identity-based spoofing attacks in mobile wireless networks. Also, this approach determines the number of attackers who used the same node identity to masquerade as legitimate device. Moreover, multiple adversaries can be localized accurately. By eliminating attackers the proposed system enhances network performance. We have evaluated our technique through simulation using an 802.11 (WiFi network and an 802.15.4 (Zigbee networks. The results prove that MODELWIN can detect spoofing attacks with a very high detection rate and localize adversaries accurately.

  8. Detection of Spoofed MAC Addresses in 802.11 Wireless Networks

    Science.gov (United States)

    Tao, Kai; Li, Jing; Sampalli, Srinivas

    Medium Access Control (MAC) address spoofing is considered as an important first step in a hacker's attempt to launch a variety of attacks on 802.11 wireless networks. Unfortunately, MAC address spoofing is hard to detect. Most current spoofing detection systems mainly use the sequence number (SN) tracking technique, which has drawbacks. Firstly, it may lead to an increase in the number of false positives. Secondly, such techniques cannot be used in systems with wireless cards that do not follow standard 802.11 sequence number patterns. Thirdly, attackers can forge sequence numbers, thereby causing the attacks to go undetected. We present a new architecture called WISE GUARD (Wireless Security Guard) for detection of MAC address spoofing on 802.11 wireless LANs. It integrates three detection techniques - SN tracking, Operating System (OS) fingerprinting & tracking and Received Signal Strength (RSS) fingerprinting & tracking. It also includes the fingerprinting of Access Point (AP) parameters as an extension to the OS fingerprinting for detection of AP address spoofing. We have implemented WISE GUARD on a test bed using off-the-shelf wireless devices and open source drivers. Experimental results show that the new design enhances the detection effectiveness and reduces the number of false positives in comparison with current approaches.

    According to the electromagnetic field distributions, there exist two kinds of coupled spoof surface plasmon polaritons (SSPPs), the symmetric and anti-symmetric modes, in the three-dimensional (3D) subwavelength spoof-insulator-spoof (SIS) waveguide. We study the dispersion and excitation of the two kinds of coupled SSPPs supported by the 3D SIS waveguide. The evolution of the dispersion with the thickness and gap width of the waveguide is numerically investigated, and we give a theoretical analysis according to the coupling mechanism. Specially, based on the coupling mechanism, we design a zipper structure, through which the excitation and propagation of the anti-symmetric coupled modes can be realized effectively.

  10. User-Centric Key Entropy: Study of Biometric Key Derivation Subject to Spoofing Attacks

    Directory of Open Access Journals (Sweden)

    Lavinia Mihaela Dinca

    2017-02-01

    Full Text Available Biometric data can be used as input for PKI key pair generation. The concept of not saving the private key is very appealing, but the implementation of such a system shouldn’t be rushed because it might prove less secure then current PKI infrastructure. One biometric characteristic can be easily spoofed, so it was believed that multi-modal biometrics would offer more security, because spoofing two or more biometrics would be very hard. This notion, of increased security of multi-modal biometric systems, was disproved for authentication and matching, studies showing that not only multi-modal biometric systems are not more secure, but they introduce additional vulnerabilities. This paper is a study on the implications of spoofing biometric data for retrieving the derived key. We demonstrate that spoofed biometrics can yield the same key, which in turn will lead an attacker to obtain the private key. A practical implementation is proposed using fingerprint and iris as biometrics and the fuzzy extractor for biometric key extraction. Our experiments show what happens when the biometric data is spoofed for both uni-modal systems and multi-modal. In case of multi-modal system tests were performed when spoofing one biometric or both. We provide detailed analysis of every scenario in regard to successful tests and overall key entropy. Our paper defines a biometric PKI scenario and an in depth security analysis for it. The analysis can be viewed as a blueprint for implementations of future similar systems, because it highlights the main security vulnerabilities for bioPKI. The analysis is not constrained to the biometric part of the system, but covers CA security, sensor security, communication interception, RSA encryption vulnerabilities regarding key entropy, and much more.

    2014-04-01

    Full Text Available In this paper, the propagation characteristics of spoof surface plasmon polaritons (SPPs on infinitely thin corrugated metal strips are theoretically analyzed. Compared with the situations of infinitely thick lateral thickness, the infinitely thin lateral thickness leads to lower plasma frequency according to the analyses. The propagation lengths and the binding capacity of the spoof SPPs are evaluated based on the derived dispersion equation. The effects of different lateral thicknesses are also investigated. At the end, a surface wave splitter is presented using infinitely thin corrugated metal strip. Other functional planar or flexible devices can also be designed using these metal strips in microwave or terahertz regimes.

    In this paper, we demonstrated that a 90°-bended imaging of spoof surface acoustic waves with subwavelength resolution of 0.316λ can be realized by a 45° prism-shaped surface phononic crystal (SPC), which is composed of borehole arrays with square lattice in a rigid plate. Furthermore, by combining two identical prism-shaped phononic crystal to form an interface (to form a line-defect), the excited spoof surface acoustic waves can be split into bended and transmitted parts. The power ratio between the bended and transmitted surface waves can be tuned arbitrarily by adjusting the defect size. This acoustic system is believed to have potential applications in various multifunctional acoustic solutions integrated by different acoustical devices.

    Richard Joseph Elston, known for his development of innovative astronomical instrumentation, died on 26 January 2004 in Gainesville, Florida, after a four-year battle with Hodgkin's lymphoma. A professor of astronomy at the University of Florida, Richard had an unusually broad range of interests and skills, and a willingness to share his passion for astronomy with others, which made him a highly valued member of the astronomical community. Born 1 July 1960, in Albuquerque, New Mexico, Richard was the son of a geologist father and journalist mother. His childhood interest in astronomy and instrumentation matured as he majored in physics and astronomy at the University of New Mexico (BS, 1983) under the mentorship of Michael Zeilik. Richard pursued his PhD in astronomy at the University of Arizona and earned his degree in 1988. He pioneered the use of IR arrays for deep imaging surveys of the sky to study galaxy formation, and completed his thesis Search for Rapidly Forming Galaxies at High Redshift under the direction of George Rieke. Richard's graduate work included the first detection of galaxies at intermediate redshifts with evolved populations too red to have been identifiable from optical imaging surveys alone. In the Astrophysical Journal Letters in 1988, he, George Rieke, and Marcia Rieke reported the discovery of this new class of galaxies, now known as EROs (Extremely Red Objects), important as the possible progenitors of present day elliptical galaxies. Following post-doctoral positions at Kitt Peak National Observatory from 1988 to 1991 and at the Observatories of the Carnegie Institution of Washington from 1991 to 1992, Richard joined the scientific staff of Cerro Tololo Inter-American Observatory in Chile, part of the NSF's National Optical Astronomy Observatory. By 1994, he had become head of CTIO's IR instrumentation program and was leading the development of new instruments for the US astronomical community. In 1996, Richard married astronomer

  13. Spoof surface plasmon based planar antennas for the realization of Terahertz hotspots

    Science.gov (United States)

    Zhang, Yusheng; Han, Zhanghua

    2015-01-01

    Novel spoof surface plasmon based terahertz (THz) antennas are realized using a few number of rectangular grooves perforated in ultrathin metal stripes and the properties of them, including both scattering cross sections and field enhancement, are numerically analyzed. The dependence of these properties on the incident angle and groove number is discussed and the results show that sharp resonances in scattering cross section spectra associated with strong local field enhancement can be achieved. These resonances are due to the formation of Fabry-Perot resonances of the spoof surface plasmon mode and it is found that the order of resonance exhibiting strongest field enhancements is found to coincide with the number of grooves at normal incidence, due to hybridization of the antenna resonance with the individual groove resonance. The terahertz hotspots within the grooves at resonances due to the local field enhancement may open up new possibilities for the investigation of terahertz-matter interactions and boost a variety of THz applications including novel sensing and THz detections. The planar stripe antennas with sharper resonances than dipolar-like resonances, together with their ease of fabrication may also promise new design methodology for metamaterials. PMID:26691003

  15. Method of lines solution of Richards` equation

    Energy Technology Data Exchange (ETDEWEB)

    1996-12-31

    We consider the method of lines solution of Richard`s equation, which models flow through porous media, as an example of a situation in which the method can give incorrect results because of premature termination of the nonlinear corrector iteration. This premature termination arises when the solution has a sharp moving front and the Jacobian is ill-conditioned. While this problem can be solved by tightening the tolerances provided to the ODE or DAE solver used for the temporal integration, it is more efficient to modify the termination criteria of the nonlinear solver and/or recompute the Jacobian more frequently. In this paper we continue previous work on this topic by analyzing the modifications in more detail and giving a strategy on how the modifications can be turned on and off in response to changes in the character of the solution.

    Richard Goldschmidt famously rejected the notion of atomic and corpuscular genes, arranged on the chromosome like beads-on-a-string. I provide an exegesis of Goldschmidt's intuition by analyzing his repeated and extensive use of metaphorical language and analogies in his attempts to convey his notion of the nature of the genetic material and specifically the significance of chromosomal pattern. The paper concentrates on Goldschmidt's use of metaphors in publications spanning 1940-1955.

    We numerically and experimentally demonstrate a plasmonic metamaterial whose unit cell is composed of an ultrathin metallic disk and four ultrathin metallic spiral arms at terahertz frequencies, which supports both spoof electric and magnetic localized surface plasmon (LSP) resonances. We show that the resonant wavelength is much larger than the size of the unit particle, and further find that the resonant wavelength is very sensitive to the particle’s geometrical dimensions and arrangements. It is clearly illustrated that the magnetic LSP resonance exhibits strong dependence to the incidence angle of terahertz wave, which enables the design of metamaterials to achieve an electromagnetically induced transparency effect in the terahertz frequencies. This work opens up the possibility to apply for the surface plasmons in functional devices in the terahertz band. PMID:27277417

It is a book on ‘theorizing’. And that makes all the difference. Swedberg has chosen the term ‘art......’, but also ‘craft’, to emphasize the practical side of doing theory. This topic has been strangely absent, not just in sociology but in the social sciences in general. In order to see this absence, we should ask ourselves how education in sociology is conventionally organized. The answer is by a taken...

This brash New York-born American physicist startled the more conservative giants of European physics with his endless ability to improvise. Indeed, later in life, Feynman became an accomplished bongo player. Feynman's legacy to physics was his ability to simplify complex equations and clarify fundamental principles through the use of graphs.

    Richard von Volkmann (1830-1889), one of the most important surgeons of the 19(th) century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867-1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the "antiseptic technique" to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann's contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children's fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

  7. Seeing Scale: Richard Dunn’s Structuralism

    Directory of Open Access Journals (Sweden)

    Keith Broadfoot

    2012-11-01

    Full Text Available Writing on the occasion of a retrospective of Richard Dunn’s work, Terence Maloon argued that ‘structuralism had an important bearing on virtually all of Richard Dunn’s mature works’, with ‘his modular, “crossed” formats’ being the most obvious manifestation of this. In this article I wish to reconsider this relation, withdrawing from a broad consideration of the framework of structuralism to focus on some of the quite particular ideas that Lacan proposed in response to structuralism. Beginning from a pivotal painting in the 1960s that developed out of Dunn’s experience of viewing the work of Barnett Newman, I wish to suggest a relation between the ongoing exploration of the thematic of scale in Dunn’s work and the idea of the symbolic that Lacan derives from structuralist thought. This relation, I argue, opens up a different way of understanding the art historical transition from Minimalism to Conceptual art.

  8. Anti-spoof touchless 3D fingerprint recognition system using single shot fringe projection and biospeckle analysis

    Fingerprint is a unique, un-alterable and easily collected biometric of a human being. Although it is a 3D biological characteristic, traditional methods are designed to provide only a 2D image. This touch based mapping of 3D shape to 2D image losses information and leads to nonlinear distortions. Moreover, as only topographic details are captured, conventional systems are potentially vulnerable to spoofing materials (e.g. artificial fingers, dead fingers, false prints, etc.). In this work, we demonstrate an anti-spoof touchless 3D fingerprint detection system using a combination of single shot fringe projection and biospeckle analysis. For fingerprint detection using fringe projection, light from a low power LED source illuminates a finger through a sinusoidal grating. The fringe pattern modulated because of features on the fingertip is captured using a CCD camera. Fourier transform method based frequency filtering is used for the reconstruction of 3D fingerprint from the captured fringe pattern. In the next step, for spoof detection using biospeckle analysis a visuo-numeric algorithm based on modified structural function and non-normalized histogram is proposed. High activity biospeckle patterns are generated because of interaction of collimated laser light with internal fluid flow of the real finger sample. This activity reduces abruptly in case of layered fake prints, and is almost absent in dead or fake fingers. Furthermore, the proposed setup is fast, low-cost, involves non-mechanical scanning and is highly stable.

    Large-scale network environments require effective detection and response methods against DDoS attacks. Depending on the advancement of IT infrastructure such as the server or network equipment, DDoS attack traffic arising from a few malware-infected systems capable of crippling the organization's internal network has become a significant threat. This study calculates the frequency of network-based packet attributes and analyzes the anomalies of the attributes in order to detect IP-spoofed DDoS attacks. Also, a method is proposed for the effective detection of malware infection systems triggering IP-spoofed DDoS attacks on an edge network. Detection accuracy and performance of the collected real-time traffic on a core network is analyzed thru the use of the proposed algorithm, and a prototype was developed to evaluate the performance of the algorithm. As a result, DDoS attacks on the internal network were detected in real-time and whether or not IP addresses were spoofed was confirmed. Detecting hosts infected by malware in real-time allowed the execution of intrusion responses before stoppage of the internal network caused by large-scale attack traffic.

It’s the time of the fall of every certainty, is the era of “post”, after the tradition, after metaphysics, after the truth, and that requires more effort than any other constant reflection. The neopragmatismo seems to be an effective investigative tool for conducting this reflection and a vantage point to carry on a conversation around the issues of education. In particular, the author intended to refer to the work of Richard Rorty, the author who more than others reflected on the encounter between two important pragmatist tradition: that of classical pragmatism and the “continental” or responsible for the development of a new European concept of truth, understood as a critical and interpretative.

    2018-03-01

    An active beam steering structure comprising the spoof surface plasmon polariton (SSPP) waveguide is presented. The proposed structure consists of two stages: the two arms structure as a Mach-Zehnder interferometer (MZI), and free space propagation stage. The SSPP waveguide includes periodic grooves, which are filled with a thin layer of doped semiconductor like GaAs. By applying electric voltage at the electrodes on top of the waveguide, the depletion layer thickness and the effective refractive index of the dielectric inside the grooves can be changed. The effective refractive index of the dielectric inside the groove is derived analytically and the phase change of the propagation wave along the single sided SSPP waveguide is calculated as a function of input voltage. The relation between the input signal and the angle of maximum radiation of output beam is investigated and the linearity is improved. We have shown that the MZI beam steering section has the capability to bend the electromagnetic beam about 42 degrees. At the end, we presented an application of the proposed beam steering device as a spatially accumulated phase difference structure that can be utilized in devices such as digital-to-analog converter (DAC).

    2016-02-01

    Backward wave with anti-parallel phase and group velocities is one of the basic properties associated with negative refraction and sub-diffraction image that have attracted considerable interest in the context of photonic metamaterials. It has been predicted theoretically that some plasmonic structures can also support backward wave propagation of surface plasmon polaritons (SPPs), however direct experimental demonstration has not been reported, to the best of our knowledge. In this paper, a specially designed plasmonic metamaterial of corrugated metallic strip has been proposed that can support backward spoof SPP wave propagation. The dispersion analysis, the full electromagnetic field simulation and the transmission measurement of the plasmonic metamaterial waveguide have clearly validated the backward wave propagation with dispersion relation possessing negative slope and opposite directions of group and phase velocities. As a further verification and application, a contra-directional coupler is designed and tested that can route the microwave signal to opposite terminals at different operating frequencies, indicating new application opportunities of plasmonic metamaterial in integrated functional devices and circuits for microwave and terahertz radiation.

    Richard D. Schwartz, Professor Emeritus of Astronomy, died at his home in Sequim, WA, after a nearly 3 year battle against pancreatic cancer. Richard was born in Pretty Prairie, Kansas. He was active in sports and band and graduated in 1959. After completing a BS at Kansas State, and a Master's degree in Divinity at Union Seminary in NY, he further studied astrophysics, receiving his doctorate from University of Washington in 1973. When Dick arrived at the University of Missouri-St. Louis in 1975, he was the only astronomer in the Department of Physics. He built the astronomy program and initiated the B.S. in physics with an astrophysics option that the majority of physics majors choose. Dick was a wonderful teacher and provided outstanding leadership to the campus. He designed and provided oversight on the construction of the campus observatory that was completed in 1981. Since that time the observatory has served as both a teaching and research facility. It is also used for monthly public open houses that draw hundreds of people annually to the campus to view the moon, stars, and planets. Upon his retirement in 2003, the Board of Curators approved naming the campus observatory the "Richard D. Schwartz Observatory" in honor of his distinctive service to the University of Missouri-St. Louis. Just as important as Dick's service to promote public interest in astronomy was his effort to make the campus observatory a research facility. Dick equipped and maintained the observatory with state-of-art detectors that allowed students to get their first taste of scientific research. From 1991-2003, he managed the campus program for the NASA/Missouri Space Grant Consortium and mentored over 30 research students in projects at the observatory. Some of the results have been published in astronomical journals. Many of those students went on to graduate schools and several have achieved tenure and distinction at major universities. In addition to Dick's service to the University

  18. Richard Murphy: a life in writing

    2006-07-01

    Full Text Available The Irish poet Richard Murphy published his autobiography “The kick: a life among writers” in 2003. From a slightly different perspective the subtitle of this work could be rewritten as “A life in writing” since it is an account of the agencies that moulded a life devoted to creative writing which forms the book’s essential impetus. The memoir is based on notebooks which Murphy kept throughout his life “to hold the scraps of verse, elusive images, dreams, desires and revelations” to be developed into poetry. Apart from contextualising his poetry by registering the relationships, circumstances and landscapes from which it germinated, Murphy also tells of the creative process itself and the personal poetics underlying this process. This article explores what is regarded as the central determining feature of Murphy’s identity as poet, namely the relationship between the creative self and a particular place, where the concept of “place” is seen as a cultural palimpsest which represents not only physical qualities, but also the shaping and development of the landscape through time according to a certain way of life.

    Full Text Available It could be argued that an important feature of Richard Murphy’s work, and of his identity as a poet is the relationship between the creative self and a particular place, where ‘place’ should be understood as referring not just to physical qualities of the natural environment, but in a broader sense to denote an environment in which everything is interrelated and connected, and in which there is no sharp division between the natural and the human. The landscape providing inspiration for Murphy’s poetic imagination is the landscapes and seascapes of Connemara in north-west Ireland. In 1959 he settled in this environment which was to be his base for the next 20 years and from this period and this location emanated the bulk of his poetic oeuvre. For Murphy committing to a life of writing poetry necessarily means being in the Connemara landscape. Returning to this environment in adulthood represents a quest for recovering childhood feelings, of belonging and love, as connected to particular places. Murphy’s Connemara poems could be read as an account of this process of re-placement, as a type of autobiographical text in which the artist creates a ‘double portrait’: in writing about the landscape he also writes about himself, creating a place-portrait which is, at the same time, a self-portrait.

    Full Text Available Finger-vein recognition, a new and advanced biometrics recognition method, is attracting the attention of researchers because of its advantages such as high recognition performance and lesser likelihood of theft and inaccuracies occurring on account of skin condition defects. However, as reported by previous researchers, it is possible to attack a finger-vein recognition system by using presentation attack (fake finger-vein images. As a result, spoof detection, named as presentation attack detection (PAD, is necessary in such recognition systems. Previous attempts to establish PAD methods primarily focused on designing feature extractors by hand (handcrafted feature extractor based on the observations of the researchers about the difference between real (live and presentation attack finger-vein images. Therefore, the detection performance was limited. Recently, the deep learning framework has been successfully applied in computer vision and delivered superior results compared to traditional handcrafted methods on various computer vision applications such as image-based face recognition, gender recognition and image classification. In this paper, we propose a PAD method for near-infrared (NIR camera-based finger-vein recognition system using convolutional neural network (CNN to enhance the detection ability of previous handcrafted methods. Using the CNN method, we can derive a more suitable feature extractor for PAD than the other handcrafted methods using a training procedure. We further process the extracted image features to enhance the presentation attack finger-vein image detection ability of the CNN method using principal component analysis method (PCA for dimensionality reduction of feature space and support vector machine (SVM for classification. Through extensive experimental results, we confirm that our proposed method is adequate for presentation attack finger-vein image detection and it can deliver superior detection results compared

    Dr. Richard B. Dunn, astronomer emeritus at the National Solar Observatory, died of a heart attack on September 29, 2005. He was recognized as one of the foremost experimental solar physicists. His innovative designs for telescopes and instruments led to many important discoveries in solar physics. Born in Baltimore, Maryland, in 1927 and raised in Minneapolis, Minnesota, Dick's parents were Dr. Halbert L. Dunn and Katherine Brandner. Halbert (MD, Ph.D., F.A.P.H.A.) was an physician who became Chief of the National Office of Vital Statistics, Public Health Service. He published a paper "High Level Wellness for Man and Society" that became the founding paper of the field of wellness health care. After their divorce in 1942, Katherine moved to New York and became a social worker. Dick had two older brothers who died before him, Halbert (born in 1921, who became a civil engineer) and Robert (born in 1924, who became an architect). Dick earned a BS in mechanical engineering and an MS in astronomy at the University of Minnesota. At the end of World War II he served in the United States Army in Japan. For his master's degree, Dick undertook the design and construction of a Lyot-type birefringent filter for observations of solar prominences. This early work led to his acceptance at Harvard, where Professor Donald Menzel encouraged him to continue his work with the 15-inch Cambridge telescope. In 1951 he conducted part of his doctoral thesis work at the fledgling Sacramento Peak Observatory in southern New Mexico. The observatory director, Dr. John Evans, was impressed with Dick's outstanding instrumental talents and invited him to join as one of the first scientific staff members. During his first few years at Sac Peak, Dick developed two more birefringent filter systems including one with an integrated coronagraph. With this system, he produced the best prominence and spicule observations ever obtained. Dick's career was dedicated to obtaining solar observations of the

    2013-09-01

    We propose the use of correlation mapping optical coherence tomography (cmOCT) to deliver additional biometrics associated with the finger that could complement existing fingerprint technology for law enforcement applications. The current study extends the existing fingerprint paradigm by measuring additional biometrics associated with sub-surface finger tissue such as sub-surface fingerprints, sweat glands, and the pattern of the capillary bed to yield a user-friendly cost effective and anti-spoof multi-mode biometric solution associated with the finger. To our knowledge no other method has been able to capture sub-surface fingerprint, papillary pattern and horizontal vessel pattern in a single scan or to show the correspondence between these patterns in live adult human fingertip. Unlike many current technologies this approach incorporates 'liveness' testing by default. The ultimate output is a biometric module which is difficult to defeat and complements fingerprint scanners that currently are used in border control and law enforcement applications.

    Richard Dawkins will speak on biology, Gerard ‘t Hooft will focus on physics, and Alain Connes will discuss mathematics. CERN scientists probe ever-deeper levels of matter and their interactions, but can we say that the patterns they see are truly fundamental? Does the universe obey the same laws throughout? Since mathematical constructions can be true in the absence of any relation to the physical world, is mathematics more fundamental than physics? Extraterrestrial life would probably look much different from that on Earth, but natural selection still be fundamental to their evolution?

    2010-01-01

    Richard von Volkman was one of the most famous and important surgeons in the 19th century. He pioneered antiseptic procedures and was especially known for his achivements in orthopedic surgery. Von Volkmann was born in Leipzig, Germany and attended medical schools in Giessen, Halle, and Berlin. Starting in 1867, he worked as a professor of surgery at the University of Halle, also leading its surgical clinic. He was active as a surgeon during Seven Weeks' War with Austria in 1866 and the Franco-Prussian war 1870/1871, in the latter as consulting Generalarzt. He was important in the introduction of antiseptic wound treatment in Germany, and through it to the United States of America. Two observations in orthopaedic surgery bear his name to these days: Volkmans contracture and Heuter-Volkmans low. Volkmann also wrote poetry under the name Richard Leander and his book entitled "Dreams by French Firesides" which still has a place in literature. He died of paralysis due to a chronic spinal disease, following a prolonged illness, in the Binswanger institution in Jena in 1889, at the top of his careere.

    Directory of Open Access Journals (Sweden)

    Robert L. Miller

    2006-03-01

    Full Text Available Handling Qualitative Data: A Practical Guide is an introductory textbook covering all stages of qualitative research from the initial conceptualisation of a project, through data collection and analysis, to writing up. The author, Lyn RICHARDS, is a well-known developer of two key qualitative software analysis packages, NUD*IST and NVivo. While RICHARDS clearly advocates the use of qualitative analysis software, the text is "generic" and could be used in tandem with any qualitative software package. The book concentrates on practical advice about the use of software to manage and analyse qualitative data, and provides insights in these areas. The consideration of issues around team-based qualitative research is another strong point. However, due in part to its short length, the overall coverage of topics tends to be superficial. In itself, the book does not provide sufficient detailed support for a student who would like to use it as her/his main source of guidance for carrying out a qualitative research project.

    2017-12-01

    Full Text Available The article deals with the teleological argument, or argument from design, as expounded by a famous English Protestant theologian Richard Baxter, one of the leading 17-th century English Puritans, in his work “The Reasons of the Christian Religion”. Natural theology, providing arguments for the existence of God based on reason and without appeal to the Revelation, has always played a vital role throughout the entire history of theological thought. The most popular was the so called teleological argument, or the argument from design, which stands out among all rational arguments for the existence of the Creator. It is mostly known from the “Fifth Way” of the medieval Scholastic philosopher Thomas Aquinas and a famous work “Natural Theology” by an English 19-th century theologian William Paley. The foundation for the modern research in the area was laid during the age of the Scientific Revolution of the 17th century English nature philosophers and theologians, especially Robert Boyle, who believed the teleological argument to be the key element of Natural Theology. His friend and confessor, Richard Baxter, a prominent representative of the Puritan Natural Theology, mostly known by his theological works, paved the way for Natural Theology both in his own time and the following centuries. His work was thought to be the best collection of the evidences for Christianity.

  16. The Paradox of the Public Realm in Richard Rorty

    2008-12-01

    Full Text Available The concepto of the public sphere in Richard Rorty's philosophy, inherited of liberal tradition, allows be treated as a part of a game of language called democratic liberalism. One of the rules for validating a move in this game consists in taking for granted the distinction between the public and the private spheres. Richard Rorty thought that democratic liberalism did not need any foundation beyond the way to play it; its only criteria would be the game's practices, according an utopia which would allow us to make more movements in the game. That is, democratic liberalism does not require foundations, but just practices for achieving a social hioe inspired on freedom and pluralism. This kind of utopia, based upon the non-cruelty principle, would make possible an inclusive society where everyone would have a place for their own private vocabulary. In this way, Rorty would have linked freedom and solidarity. However, this language-game reveals the paradox of the link which implies the meaning of the public shere. Herein, freedom is not a sufficient condition of solidarity; hence, there is no place for social inclusion in Rorty's language game.

    Directory of Open Access Journals (Sweden)

    Martha Palacio Avendaño

    2008-01-01

    Full Text Available El concepto de lo público en Richard Rorty, heredero de la tradición liberal, admite ser tratado como parte de un juego del lenguaje denominado liberalismo democrático. En ese sentido, una de las reglas de este juego para saber si una jugada es válida consiste en asumir la distinción entre esfera pública y privada. Richard Rorty pensó que este juego no requería fundamentación más allá de la forma de jugarlo, que el criterio en que se apoyaría estaba en las prácticas que tienen lugar dentro del mismo con arreglo a sostener una utopía que permitiera hacer cada vez más jugadas. Esto es, el liberalismo democrático no requería basarse en algo más allá de las prácticas conducentes a lograr una esperanza social alentada por la libertad en defensa del pluralismo. Su utopía liberal, guiada por el principio de la no-crueldad, haría posible una sociedad inclusiva en la que todos tuvieran espacio para su léxico privado. De este modo, Rorty habría vinculado libertad y solidaridad, pero su juego del lenguaje permite advertir la paradoja del vínculo que implicaría el sentido de lo público. Aquí, la libertad no es condición suficiente de la solidaridad, de modo que la inclusión social no tiene cabida en su juego del lenguaje.

    Full Text Available Quando consideramos a extensão da obra dramática de Richard Wagner, não causa estranheza que seus textos teóricos sejam praticamente desconhecidos. No entanto, um de seus escritos, intitulado Beethoven, influenciou decisivamente a elaboração de um livro famoso, hoje considerado um capítulo importante da história da estética, O nascimento da tragédia. Este artigo pretende analisar este escrito de Wagner na intenção de desvendar o que pode ter sido tão determinante na leitura que Nietzsche fez dele, e que o levou ao ponto de citá-lo de modo efusivo no primeiro prefácio da sua obra de estréia, dedicado àquele que, até então, era seu grande mestre e amigo e, como veremos, uma influência não só musical, mas também teórica.If we consider the magnitude of the Richard Wagner's dramatic work, it will be not strange to realize that his theoretical texts are almost entirely unknown. However, one of his writings, entitled Beethoven, exercised decisive influence upon the composition of The birth of tragedy, a famous book regarded nowadays as an essential moment of the history of aesthetics. The purpose of this paper is to examine this Wagner's writing aiming to unriddle which determinative motive brought Nietzsche to mention it enthusiastically in the original foreword of his first work, dedicated to whom which, until that moment, were his master and friend and exercised upon him an influence both musical and theoretical.

  4. Saxon Obsequies: the Early Medieval Archaeology of Richard Cornwallis Neville

    Directory of Open Access Journals (Sweden)

    Howard Williams

    2013-04-01

    Full Text Available This paper investigates the origins of British Anglo-Saxon archaeology by focusing on the work of one early Victorian archaeologist: Richard Cornwallis Neville. The seemingly descriptive and parochial nature of Neville’s archaeological pursuits, together with the attention he afforded to Romano-British remains, has impeded due recognition, and critical scrutiny, of his contributions to the development of early Medieval burial archaeology. Using his archaeological publications as source material, I will show how Neville’s interpretations of Saxon graves were a form of memory work, defining his personal, familial and martial identity in relation to the landscape and locality of his aristocratic home at Audley End, near Saffron Walden, Essex. Subsequently, I argue that Neville’s prehistoric and Romano-British discoveries reveal his repeated concern with the end of Roman Britain and its barbarian successors. Finally, embodied within Neville’s descriptions of early Medieval graves and their location we can identify a pervasive Anglo-Saxonism. Together these strands of argument combine to reveal how, for Neville, Saxon graves constituted a hitherto unwritten first chapter of English history that could be elucidated through material culture and landscape.

Comme les faces serpentines d’un ruban de Möbius lové autour de l’illimité et de l’intemporel, le texte, tendu entre ses deux infinis – l’univers et l’enfant – révise la portée, la conception, la structure et le style du genre romanesque. Délaissant Aristote pour Einstein, Operation Wandering Soul se place sur le terrain de la cosmologie. Le récit, qui rassemble la kyrielle des grands ralliements juvéniles et leurs vains pèlerinages, concentre l’espace-temps dans une présentation qui évoque la « somme des histoires » de Richard Feynman. La contraction de l’espace-temps opérée par le roman ne fait pas de celui-ci un hymne simpliste au global (catégorie déjà aussi datée que celle des malheureux vétérans du Vietnam, mais capte au contraire la conscience grandissante d’une existence sans origine qui s’étend à perte de vue au-delà de ses coordonnées supposées. Le roman s’enroule sur lui-même tout en s’épanchant au dehors, boucle ses cadres et ses détours tout en desserrant leur emprise. Il fait tourner la roue de ses récits comme des planètes en rotation, la ronde d’un système solaire, le tourbillon d’une galaxie. La conscience que présente Operation Wandering Soul ne se résume donc pas au seul point de vue de l’âme errante qu’est le personnage de Kraft, mais consiste en la somme de tous les temps et de tous les lieux, de leurs strates accumulées comme une conscience en acte, complexe et tissée de réseaux, qui n’appartient à personne et est partagée par tous. Cette accumulation organise le jeu des perspectives multiples qui instaurent l’acte de lecture et sont instaurées par lui. À cet égard, lire constitue ici une physique des oubliés.Richard Powers’ novel Operation Wandering

  6. PolyRES: A polygon-based Richards equation solver

    This document describes the theory, implementation, and use of a software package designed to solve the transient, two-dimensional, Richards equation for water flow in unsaturated-saturated soils. This package was specifically designed to model complex geometries with minimal input from the user and to simulate groundwater flow related to assessment of low-level radioactive waste disposal sites and engineered facilities. The spatial variation of the hydraulic properties can be defined across individual polygon-shaped subdomains, called objects. These objects combine to form a polygon-shaped model domain. Each object can have its own distribution of hydraulic parameters. The resulting model domain and polygon-shaped internal objects are mapped onto a rectangular, finite-volume, computational grid by a preprocessor. This allows the user to specify model geometry independently of the underlying grid and greatly simplifies user input for complex geometries. In addition, this approach significantly reduces the computational requirements since complex geometries are actually modeled on a rectangular grid. This results in well-structured, finite difference-like systems of equations that require minimal storage and are very efficient to solve. The documentation for this software package includes a user`s manual, a detailed description of the underlying theory, and a detailed discussion of program flow. Several example problems are presented that show the use and features of the software package. The water flow predictions for several of these example problems are compared to those of another algorithm to test for prediction equivalency.

  7. Forjando nuestras democracias: entre Richard Rorty y Vladimiro Montesinos

    2001-07-01

    Full Text Available This article aims at explaining the recent history of Peru, in an exercise in which it is possible to extract lessons about the way Latin American democracies have been(or have not been forged. The text draws a parallel between the ideas developed by Richard Rorty in his recently published book, Forjar nuestro país. El pensamiento de izquierdas en los Estados Unidos del siglo XX, and the events in Fugimori's and Montesinos' Peru. If, according to what Rorty believes, "national pride is for the countries what self esteem is for individuals ... " how would it be possible to narrate a history in which there are few motives to be proud of? Trying to escape fatalism and sarcasm, the text tries to show that Montesino's political course is, symbolically, a summary of the decomposition process of Peruvian democracy. Secondly, the text analyses the movements of the political left wing and deals with the support the regimen received from inside and outside the country, a support that was largely based on the illusion of political stability. Finally, it states, as Rorty does, that in order to forge democracies it is necessary for us to be deeply committed to the defense of the State of Right.

    This paper concentrates on two aspects of the work of Leipzig brain researcher Richard Arwed Pfeifer (1877-1957). It has been little known that Pfeifer, like Prinzhorn, collected paintings by his schizophrenic patients. In works about these paintings, he tried to decipher their specific attraction and the possibility of differentiating artworks of sane artists from those of insane ones. From experimental research he concluded that the "demonic element" was of utmost importance, which however could temporarily be brought about by sane artists too. Trained in medicine and psychology by Wundt, Flechsig, and Niessl von Mayendorf, Pfeifer was appointed as the first associate professor of brain research in Germany in 1927. Until now he has been appreciated for reestablishing the angioarchitecture of the brain, mainly due to his works on the distribution of capillaries in the brain achieved by a particular method of injection which he developed. Moreover he contributed new findings on the interrelations of the capillaries and thus finally disproved the existence of so-called terminal arteries of Cohnheim.

  9. Transcendence, Taxis, Trust: Richard Kearney and Jacques Derrida

    Full Text Available Whatever else it takes to drive a taxi, it takes trust. Day after day, the driver has to decide whether the other is or is not trustworthy. I take the taxi as a test case to analyze and assess Richard Kearney’s diacritical hermeneutics of the other. I argue that Kearney functionalizes the concept of transcendence in order to connect the transcendence of the finite other to the transcendence of the infinite other. However, in his central critique of the deconstructionists following Jacques Derrida, Kearney counters his connection. While Kearney’s critique of Derrida’s account of absolute alterity is correct and compelling, I argue that Derrida’s critique of a distinction between the trustworthy other and the non-trustworthy other might be more crucial than Kearney contends. Insisting on openness to the other’s otherness, Derrida provokes any hermeneutic of the other to trust in transcendence. The taxi is taken as a test to illustrate the implications which diacritical and deconstructive drivers might have for evaluating the entanglement of ethics and eschatology—inside and outside the taxi.

  10. Perception of Leitmotives in Richard Wagner's Der Ring des Nibelungen

    David J. Baker

    2017-05-01

    Full Text Available The music of Richard Wagner tends to generate very diverse judgments indicative of the complex relationship between listeners and the sophisticated musical structures in Wagner's music. This paper presents findings from two listening experiments using the music from Wagner's Der Ring des Nibelungen that explores musical as well as individual listener parameters to better understand how listeners are able to hear leitmotives, a compositional device closely associated with Wagner's music. Results confirm findings from a previous experiment showing that specific expertise with Wagner's music can account for a greater portion of the variance in an individual's ability to recognize and remember musical material compared to measures of generic musical training. Results also explore how acoustical distance of the leitmotives affects memory recognition using a chroma similarity measure. In addition, we show how characteristics of the compositional structure of the leitmotives contributes to their salience and memorability. A final model is then presented that accounts for the aforementioned individual differences factors, as well as parameters of musical surface and structure. Our results suggest that that future work in music perception may consider both individual differences variables beyond musical training, as well as symbolic features and audio commonly used in music information retrieval in order to build robust models of musical perception and cognition.

  11. The Crumbling Two-Story Architecture of Richard Powers’ Fictions

    Full Text Available L’alternance de deux récits différents au sein d’une même narration constitue l’une des marques les plus saillantes de la technique narrative de Richard Powers. Cependant, les rapports qu’entretiennent ces deux récits varient sensiblement d’un roman à l’autre. Ils peuvent, d’un point de vue diégétique, reposer sur un même personnage, comme dans Galatea 2.2, ou sur la rencontre ponctuelle de divers protagonistes, comme dans The Echo Maker. Il arrive aussi qu’ils explorent un enchaînement présumé de cause à effet, comme dans Gain. Plus radicalement, dans Plowing the Dark, les deux récits paraissent tisser des liens essentiellement métaphoriques qui excluent plus ou moins toute idée de métonymie. Sur le plan de la signification, les deux récits semblent parfois former une unité lorsque combinaisons, parallèles et oppositions font se lever entre eux des rapports dialectiques. Ce travail met en évidence, dans plusieurs romans de Powers, les diverses permutations de cette structure à double récit et tente de cerner ce qui pourrait en constituer le « reste », élément irréductible à toute unité thématique ou artistique. Si un tel reste existe, quel sens pourrait-il alors revêtir ?A prominent characteristic of Richard Powers’ technique is that his novels generally proceed by the alternating narration of two different stories. The relations of one story to another vary quite widely, however. On the diegetic level, the two may have a common protagonist, as in Galatea 2.2; or they may concern the different but circumstantially intersecting lives of disparate figures, as in The Echo Maker; or they may explore a possible chain of cause and effect, as in Gain. Most radically, in Plowing the Dark, their relation seems to be more or less purely metaphoric, with little or no metonymic connection at all. On the level of meaning, the two stories may seem to form unities by operating in conjunction or parallel or

  12. Desire and the Other in Richard Yates's Revolutionary Road

    2011-06-01

    Full Text Available Richard Yates’s novel Revolutionary Road did not receive much academic attention despite the fact that it is an exceptionally refined and capturing piece of fiction. It was critically acclaimed following its publication in 1961, nominated for the National Book Award in 1962 and then forgotten. Not surprisingly, the novel was “rediscovered” once a movie adaptation was made in 2008. Revolutionary Road is typically read – quite expectedly – as a story of suburban malaise and a critique of the American (suburban life in the 1950s. However, in an interview, published in Ploughshares in 1972, Yates stated that although he intended the novel to be an indictment of American life in the 1950s because of a general lust for conformity (DeWitt and Clark 66, he never planned the novel to be anti-suburban in any way. On the contrary, he hoped to make it implicit in the text that he is writing about a particular couple, the Wheelers, and what turns out to be specifically “their delusion, their problem” (DeWitt and Clark 66. In that sense, the novel should be read as a psychological exploration of the universal issues of human desire and the relationship of the individual to the pre-established (social system in which he or she lives. Consequently, it becomes clear that Yates’s novel hardly represents an indictment of a way of life, but quite the opposite: an indictment of the individual unable to adapt to the demands of the Other. In Lacanian terms, Revolutionary Road is a story about the unattainable desire to create one’s identity regardless or in spite of the socially constructed Symbolic order.

  13. Stand diameter distribution modelling and prediction based on Richards function.

    Full Text Available The objective of this study was to introduce application of the Richards equation on modelling and prediction of stand diameter distribution. The long-term repeated measurement data sets, consisted of 309 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata plantations in the southern China, were used. Also, 150 stands were used as fitting data, the other 159 stands were used for testing. Nonlinear regression method (NRM or maximum likelihood estimates method (MLEM were applied to estimate the parameters of models, and the parameter prediction method (PPM and parameter recovery method (PRM were used to predict the diameter distributions of unknown stands. Four main conclusions were obtained: (1 R distribution presented a more accurate simulation than three-parametric Weibull function; (2 the parameters p, q and r of R distribution proved to be its scale, location and shape parameters, and have a deep relationship with stand characteristics, which means the parameters of R distribution have good theoretical interpretation; (3 the ordinate of inflection point of R distribution has significant relativity with its skewness and kurtosis, and the fitted main distribution range for the cumulative diameter distribution of Chinese fir plantations was 0.4∼0.6; (4 the goodness-of-fit test showed diameter distributions of unknown stands can be well estimated by applying R distribution based on PRM or the combination of PPM and PRM under the condition that only quadratic mean DBH or plus stand age are known, and the non-rejection rates were near 80%, which are higher than the 72.33% non-rejection rate of three-parametric Weibull function based on the combination of PPM and PRM.

    2009-01-01

    It is with a great deal of both happiness and sadness that I have to announce that we are losing one of the real strengths of the Journal of Physics: Condensed Matter (JPCM). Dr Richard Palmer, our Senior Publisher, announced his retirement, and this issue marks the first without his involvement. Of course, we are happy that he will get to enjoy his retirement, but we are sad to lose such a valuable member of our team. Richard first started work at IOP Publishing in March 1971 as an Editorial Assistant with Journal of Physics B: Atomic and Molecular Physics. After a few months, he transferred to Journal of Physics C: Solid State Physics. During his first year, he was sent on a residential publishing training course and asked to sign an undertaking to stay at IOP Publishing for at least two years. Although Richard refused to sign, as he did not want to commit himself, he has remained with the journal since then. The following year, the Assistant Editor of Journal of Physics C: Solid State Physics, Malcolm Haines, walked out without notice in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of Journal of Physics C: Solid State Physics, before being given the job of Assistant Editor permanently. I am told that in those days the job consisted mainly of editing and proofreading and peer review. There was no journal development work. At some point in the early 1980s, production and peer review were split into separate departments and Richard then headed a group of journals consisting of Journal of Physics C: Solid State Physics, Journal of Physics D: Applied Physics and Journal of Physics F: Metal Physics, Semiconductor Science and Technology, Superconductor Science and Technology, Plasma Physics and Controlled Fusion, and later Nanotechnology and Modelling and Simulation

  1. Trochanteric fractures. Classification and mechanical stability in McLaughlin, Ender and Richard osteosynthesis

    Energy Technology Data Exchange (ETDEWEB)

    Herrlin, K.; Stroemberg, T.; Lidgren, L.; Walloee, A.; Pettersson, H.

    Four hundred and thirty trochanteric factures operated upon with McLaughlin, Ender or Richard's osteosynthesis were divided into 6 different types based on their radiographic appearance before and immediately after reposition with special reference to the medial cortical support. A significant correlation was found between the fracture type and subsequent mechanical complications where types 1 and 2 gave less, and types 4 and 5 more complications. A comparison of the various osteosyntheses showed that Richard's had significantly fewer complications than either the Ender or McLaughlin types. For Richard's osteosynthesis alone no correlation to fracture type could be made because of the small number of complications in this group.

  2. Novel non-periodic spoof surface plasmon polaritons with H-shaped cells and its application to high selectivity wideband bandpass filter.

    Science.gov (United States)

    Gao, Xin; Che, Wenquan; Feng, Wenjie

    2018-02-06

    In this paper, one kind of novel non-periodic spoof surface plasmon polaritons (SSPPs) with H-shaped cells is proposed. As we all know, the cutoff frequency exists inherently for the conventional comb-shaped SSPPs, which is a kind of periodic groove shape structures and fed by a conventional coplanar waveguide (CPW). In this work, instead of increasing the depth of all the grooves, two H-shaped cells are introduced to effectively reduce the cutoff frequency of the conventional comb-shaped SSPPs (about 12 GHz) for compact design. More importantly, the guide waves can be gradually transformed to SSPP waves with high efficiency, and better impedance matching from 50 Ω to the novel SSPP strip is achieved. Based on the proposed non-periodic SSPPs with H-shaped cells, a wideband bandpass filter (the 3-dB fractional bandwidths 68%) is realized by integrating the spiral-shaped defected ground structure (DGS) etched on CPW. Specifically, the filter shows high passband selectivity (Δf 3 dB /Δf 20 dB  = 0.91) and wide upper stopband with -20 dB rejection. A prototype is fabricated for demonstration. Good agreements can be observed between the measured and simulated results, indicating potential applications in the integrated plasmonic devices and circuits at microwave and even THz frequencies.

    2017-11-01

    The parameters in Richards' equation are usually calculated from experimentally measured values of the soil-water characteristic curve and saturated hydraulic conductivity. The complex pore structures that often occur in porous media complicate such parametrization due to hysteresis between wetting and drying and the effects of tortuosity. Rather than estimate the parameters in Richards' equation from these indirect measurements, image-based modelling is used to investigate the relationship between the pore structure and the parameters. A three-dimensional, X-ray computed tomography image stack of a soil sample with voxel resolution of 6 μm has been used to create a computational mesh. The Cahn-Hilliard-Stokes equations for two-fluid flow, in this case water and air, were applied to this mesh and solved using the finite-element method in COMSOL Multiphysics. The upscaled parameters in Richards' equation are then obtained via homogenization. The effect on the soil-water retention curve due to three different contact angles, 0°, 20° and 60°, was also investigated. The results show that the pore structure affects the properties of the flow on the large scale, and different contact angles can change the parameters for Richards' equation.

    Kucerka, Miroslav

    2006-01-01

    The Phare project CZ 632.02.04 'Realization of closure of a chamber in the Richard repository as input for establishing a safety case' is a follow up implementation phase of the Phare project, CZ 01.14.03 'Solution for closure of a chamber in the Richard repository'. Main objective of both projects is to propose and realize a disposal system in selected chambers of the Richard repository, which will eliminate burden from the past practices in waste management during the first phase of the Richard repository operation (1965 - 1980) and which will improve its overall long term safety. This objective will be assured by realization of the concept of so called 'hydraulic cage', which technical solution was developed by DBE Technology within the Phare project CZ 01.14.03. The solution is described in the previous presentation 'Hydraulic Cage Concept for Waste Chambers and its Technical Implementation for the Underground Richard Repository, Litomerice, Czech Republic'.

    Pascarella, Luigi; Pappas, Theodore N

    2013-02-01

    In September of 1974, Richard Nixon resigned the Presidency of the United States during an impeachment investigation concerning the Watergate Affair. One month after his resignation, the former President had an exacerbation of his chronic deep vein thrombosis. He also received a Presidential pardon from Gerald Ford on the same day that his recurrent deep vein thrombosis was diagnosed. The political, legal, and medical events that unfolded in the fall of 1974 are the substance of this report. Presidents often receive medical care that stretches the ordinary as a result of their position and the importance of their actions. The events surrounding Richard Nixon's care for deep vein thrombosis and its complications were not unusual for Presidential health care but were closely intertwined with the legal proceedings during the prosecution of the Watergate defendants.

  5. Die Musik Richard Wagners im Banat und in Rumänien. Eine Rezeptionsgeschichte

    Directory of Open Access Journals (Sweden)

    Franz Metz

    2015-12-01

    Full Text Available Richard Wagner – an ihm schieden sich die Geister schon während seines Lebens. Dies geschah nicht nur in seinen deutschen Wirkungsorten, sondern auch im Südosten Europas. Schon früh fanden seine Werke auch im Banat und in Bukarest eine weite Verbreitung und das musikliebende Publikum mischte sich damals bereits in Pro- oder Kontra-Wagner-Diskussionen ein. In einem multikulturellen Raum wie das Banat, mit jahrhundertalten multiethnischen Erfahrungen und Traditionen, stieß der Wagnerkultus zuerst auf Ablehnung, später, ab 1930, wurden seine antisemitischen Anschauungen von den faschistischen Kreisen Rumäniens demagogisch missbraucht – ähnlich wie im restlichen Europa. Doch diese besondere Seite der Richard-Wagner-Rezeption hat auch eine faszinierende Auswirkung auf das allgemeine Musikleben in Rumänien und im Banat hinterlassen.

    2017-11-01

    Sir Richard Owen, a Lancastrian, was a prominent biologist, comparative anatomist, geologist, palaeontologist and known for coining the term dinosaur. His expertise in anatomical dissection proved to be one of his biggest assets and aided his career progression at the Royal College of Surgeons and the Zoological Society. Owen's apprenticeship in Lancaster helped him to gain expertise in anatomy and anatomical dissection. The authors aim to provide some novel contextual background to his childhood in Lancaster, his affection for his hometown and his contribution to Lancaster's sanitary reform. The latter aspect of his scientific accomplishments is typically overlooked.

    Full Text Available The essay deals with the relation of prominent Czech composer Antonín Dvořák (1841–1904 to the personality and work of Richard Wagner (1813–1883. As opposed to the common opinions linking Dvořák’s name with Wagner‘s ideological opponents and placing his ‘Wagnerian’ period in the early phase of his career only, our examination shows that Dvořák’s interest in Wagner and his music was of deep and lasting nature and was significant for him throughout the whole of his life.

    Crenner, Christopher

    2002-01-01

    This paper examines diagnostic practices using the early twentieth-century medical literature and the patient correspondence and records from the clinic of Richard Cabot. What shaped medicine's rapidly growing persuasive authority in the twentieth century? Diagnostic expertise demonstrated the doctor's control over disease but offered a service of ambiguous value to patients. Cabot and his peers offered differing views on how new diagnostic techniques would influence their relationships to their patients. In his busy private clinic Cabot put into effect an exacting diagnostic process, modeled on his innovative Clinicopathological Conferences. The people who came to the clinic often sought his technical expertise but accepted his diagnostic practices and opinions sometimes only provisionally.

  2. The 1D Richards' equation in two layered soils: a Filippov approach to treat discontinuities

    Science.gov (United States)

    Berardi, Marco; Difonzo, Fabio; Vurro, Michele; Lopez, Luciano

    2018-05-01

    The infiltration process into the soil is generally modeled by the Richards' partial differential equation (PDE). In this paper a new approach for modeling the infiltration process through the interface of two different soils is proposed, where the interface is seen as a discontinuity surface defined by suitable state variables. Thus, the original 1D Richards' PDE, enriched by a particular choice of the boundary conditions, is first approximated by means of a time semidiscretization, that is by means of the transversal method of lines (TMOL). In such a way a sequence of discontinuous initial value problems, described by a sequence of second order differential systems in the space variable, is derived. Then, Filippov theory on discontinuous dynamical systems may be applied in order to study the relevant dynamics of the problem. The numerical integration of the semidiscretized differential system will be performed by using a one-step method, which employs an event driven procedure to locate the discontinuity surface and to adequately change the vector field.

  3. Wooing-Scenes in “Richard III”: A Parody of Courtliness?

    Directory of Open Access Journals (Sweden)

    Agnieszka Stępkowska

    2009-11-01

    Full Text Available In the famous opening soliloquy of Shakespeare’s Richard III, Richard mightily voices his repugnance to “fair well-spoken days” and their “idle pleasures”. He realizes his physical deformity and believes that it sets him apart from others. He openly admits that he is “not shaped for sportive tricks, nor made to court an amorous looking-glass”. Yet, his monstrosity constitutes more perhaps of his aggressive masculine exceptionality rather than of his deformity. Richard’s bullying masculinity manifests itself in his contempt for women. In the wooing scenes we clearly see his pugnacious pursuit of power over effeminate contentment by reducing women to mere objects. Additionally, those scenes are interesting from a psychological viewpoint as they brim over with conflicting emotions. Therefore, the paper explores two wooing encounters of the play, which belong the best examples of effective persuasion and also something we may refer to as ‘the power of eloquence’.

  4. Digital scenography and the mimetic aporia of Richard Wagner's Ring Cycle

    Directory of Open Access Journals (Sweden)

    Jason R. D’Aoust

    2015-12-01

    Full Text Available This article explores the visual friction between the concealment of technology and the need to stage mimetic scenes in Richard Wagner's Der Ring des Nibelungen. The article relies on the critical reception of the Wagnerian Gesamtkunstwerk in musicology, as well as in media, performance, and theatre studies. Drawing on productions and commentaries critical of the iconic Gesamtkunstwerk's attempted retrieval of a lost natural state, the article examines correlations between phantasmagoria, special effects, movement detection technology, and the interactive devices of multimedia and digital scenography. These correlations are framed within a theoretical methodology of historical discourse and media archaeologies. Three specific productions of the Ring are discussed, namely the inaugural and centenary productions at the Bayreuth Festspielhaus, as well as Robert Lepage's production for the Metropolitan Opera of New York in 2010–2012.

    Emily Buffey

    2015-03-01

    Full Text Available In response to the recent call to re-evaluate what C.S. Lewis called the ‘Drab Age’, the article reassesses one sixteenth-century poem, The Rewarde of Wickednesse (1574, and its author, Richard Robinson. The poem is framed in such a way that the topos of service is central to an understanding of Robinson’s authorial identity, an identity determined by his proclaimed status within the household of the sixth Earl of Shrewsbury. The poet claims to be one ‘of a hundreth’ serving the family during the captivity of Mary, Queen of Scots. The article locates the Rewarde of Wickednesse within the relevant geographical, literary and socio-political contexts and reveals aspects of Robinson’s artistry that have remained hitherto unexplored.

    Richard Arwed Pfeifer (1877-1957) was one of the initiators and foster fathers of the renowned child-psychiatric and special needs education workgroup at Leipzig University under Paul Schröder (1873-1941) in the 1920s and 1930s. This paper is an account of their dispute concerning the interrelations between child and adolescent psychiatry and special needs education, as well as their disagreement about whether adolescent psychopaths should be admitted to specialized child psychiatric wards or elsewhere. Moreover, Pfeifer questioned the practical relevance of the separation of constitutional and environmentally-based psychopathy and fought eugenic research, which he found incompatible with the ethics of his profession as a remedial teacher and child psychiatrist.

  7. Analytical and grid-free solutions to the Lighthill-Whitham-Richards traffic flow model

    KAUST Repository

    Mazaré, Pierre Emmanuel

    2011-12-01

    In this article, we propose a computational method for solving the Lighthill-Whitham-Richards (LWR) partial differential equation (PDE) semi-analytically for arbitrary piecewise-constant initial and boundary conditions, and for arbitrary concave fundamental diagrams. With these assumptions, we show that the solution to the LWR PDE at any location and time can be computed exactly and semi-analytically for a very low computational cost using the cumulative number of vehicles formulation of the problem. We implement the proposed computational method on a representative traffic flow scenario to illustrate the exactness of the analytical solution. We also show that the proposed scheme can handle more complex scenarios including traffic lights or moving bottlenecks. The computational cost of the method is very favorable, and is compared with existing algorithms. A toolbox implementation available for public download is briefly described, and posted at http://traffic.berkeley.edu/project/downloads/lwrsolver. © 2011 Elsevier Ltd.

    This article pays homage to the life and work of a veritable pioneer in toxicology and drug metabolism, namely a Welshman, Richard Tecwyn Williams, FRS. Professor Williams, or RT as he was known, made major contributions to knowledge about the metabolism and toxicology of drugs and xenobiotics during a scientific career spanning nearly 50 years. Author or coauthor of close to 400 research articles and reviews, including a classic book, entitled Detoxication Mechanisms, Williams and his research school investigated virtually all aspects of drug metabolism, especially conjugations. In particular, the concepts of phase 1 and phase II metabolic pathways were introduced by Williams; the biliary excretion of drugs was extensively studied as were species differences in drug metabolism and detoxication. Besides investigating the metabolism of many pharmaceutical drugs, such as sulfonamides and thalidomide, Williams and his group investigated the disposition and fate in the body of organic pesticides and recreational drugs of abuse, such as amphetamine, methamphetamine and lysergic acid diethylamide (LSD).

    During the Middle Ages, the partition of the cadaver of the elite members was a current practice, with highly technical treatment given to symbolic organs such as the heart. Considered mostly from a theoretical point of view, this notion of dilaceratio corporis has never been biologically explored. To assess the exact kind of embalming reserved to the heart, we performed a full biomedical analysis of the mummified heart of the English King Richard I (1199 A.D.). Here we show among other aspects, that the organ has been embalmed using substances inspired by Biblical texts and practical necessities of desiccation. We found that the heart was deposed in linen, associated with myrtle, daisy, mint, frankincense, creosote, mercury and, possibly, lime. Furthermore, the goal of using such preservation materials was to allow long-term conservation of the tissues, and good-smelling similar to the one of the Christ (comparable to the odor of sanctity).

    Full Text Available In this timely book Richard Peet and his team lay the foundation with an excellent analysis of the process of globalisation and the resultant emergence of the global economy. The authors are especially critical of the increasing influence of institutions like the International Monetary Fund (IMF, World Bank and World Trade Organisation (WTO on the economy and the consequences experienced by peoples, cultures and the environment. The single ideology of neo-liberalism is blamed for the undesirable outcomes. This book considers concepts of power, political interest, hegemony, discourse, responsibility and the power of practicality, in critically examining the IMF, World Bank and WTO. The conclusion is reached that “all three institutions play roles greatly different from those originally agreed to under the charters that set them up”.

  2. Plant Viability as a Function of Temperature Stress (The Richards Function Applied to Data from Freezing Tests of Growing Shoots).

    Von Fircks, H. A.; Verwijst, T.

    1993-09-01

    Frost resistance of growing Salix viminalis L. shoots was determined by rating mortality percentage under two commonly used freezing conditions: a condition in which plants were encased in crushed ice and another in which plants were moistened with tap water prior to freezing. The mortality-temperature data were fitted with a logistic function (having a fixed inflection point halfway between the asymptotes) and with a Richards function, which is a double asymptotic sigmoid function with a variable inflection point. Different frost resistance curves were obtained, depending on the freezing conditions used. However, conditions were inadequate for efficient ice nucleation under either condition. This implies that the applied freezing conditions are not suitable when the purpose is to induce and duplicate early ice crystal formation conditions. The Richards derivatives were negatively skewed in the one case and positively skewed in the other case, giving inflection points, as a function of the upper asymptote, situated at 0.37 when shoots were frosted in the presence of ice and at 0.81 when shoots were frozen in the presence of added moisture. These values differed significantly from 0.50, through which the logistic function would have forced the curves. Because of the significant asymmetry in these frost-resistance curves, the Richards function led to a more accurate reflection of the temperature-mortality course of growing Salix stems than the logistic function. The Richards function possesses the flexibility needed to describe plant injury response in terms of physical and plant physiological mechanisms. Therefore, the Richards function is recommended rather than the logistic function for the assessment of frost resistance.

    2009-11-01

    This year marks the 20th anniversary of the launch of Journal of Physics: Condensed Matter in 1989. The journal was formed from the merger of Journal of Physics C: Solid State Physics and Journal of Physics F: Metal Physics which had separated in 1971. In the 20 years since its launch, Journal of Physics: Condensed Matter has more than doubled in size, while raising standards. Indeed, Journal of Physics: Condensed Matter has become one of the leading scientific journals for our field. This could not have occurred without great leadership at the top. No one has been more responsible for this growth in both size and quality than our Senior Publisher, Richard Palmer. Richard first started work at IOP in March 1971 as an Editorial Assistant with J. Phys. B After a few months, he transferred to J. Phys.C The following year, the Assistant Editor of J. Phys. C, Malcolm Haines, left suddenly in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of J. Phys. C, before being given the job of Assistant Editor permanently. Since J. Phys. C and J. Phys. F re-merged to form Journal of Physics: Condensed Matter, Richard gradually shed his other journal responsibilities, except for Reports on Progress in Physics, to build up Journal of Physics: Condensed Matter. He has worked closely with four Editors-in-Chief of J. Phys. C and five of Journal of Physics: Condensed Matter. When Richard announced his retirement this past winter, we met it with a great deal of both happiness and sadness. Of course, we are happy that he is going to be allowed to enjoy his retirement, but we remain very sad to lose such a valuable member of our team, especially the one who had provided the heart and soul of the journal over its 20 years. We will be able to rely upon the team which Richard ably trained as

    Full Text Available In this work we study the problem of modeling identification of a population employing a discrete dynamic model based on the Richards growth model. The population is subjected to interventions due to consumption, such as hunting or farming animals. The model identification allows us to estimate the probability or the average time for a population number to reach a certain level. The parameter inference for these models are obtained with the use of the likelihood profile technique as developed in this paper. The identification method here developed can be applied to evaluate the productivity of animal husbandry or to evaluate the risk of extinction of autochthon populations. It is applied to data of the Brazilian beef cattle herd population, and the the population number to reach a certain goal level is investigated.Neste trabalho estudamos o problema de identificação do modelo de uma população utilizando um modelo dinâmico discreto baseado no modelo de crescimento de Richards. A população é submetida a intervenções devido ao consumo, como no caso de caça ou na criação de animais. A identificação do modelo permite-nos estimar a probabilidade ou o tempo médio de ocorrência para que se atinja um certo número populacional. A inferência paramétrica dos modelos é obtida através da técnica de perfil de máxima verossimilhança como desenvolvida neste trabalho. O método de identificação desenvolvido pode ser aplicado para avaliar a produtividade de criação animal ou o risco de extinção de uma população autóctone. Ele foi aplicado aos dados da população global de gado de corte bovino brasileiro, e é utilizado na investigação de a população atingir um certo número desejado de cabeças.

  5. Richard Rorty:From Anti-metaphysical Neo-Pragmatism to Rejection of Philosophy

    Full Text Available Richard Rorty is a neo-Pragmatist philosopher. For three decades, he has attacked the traditional philosophy (from Plato to Kant as well as any other epistemology searching for truth or claiming to mirror the nature in his philosophical works. Rorty holds that, according to the history of philosophy in his reading, there is no final answer to the traditional questions concerning knowledge, truth, and representation. These questions, therefore, should be dissolved and denied. He maintains that knowledge is justified belief, justification, however, being not the consequence of some correspondence between the theory or the statement, but the consequence of conversation, social practice, group consensus, and social solidarity. Rorty also thinks that democracy has priority on philosophy, disagreeing with the thesis that philosophy is the foundation of the rest of culture.Despite of usefulness of some elements and implications of Rorty’s metaphilosophy (such as his emphasis on freedom, democracy, and pluralism as well as his insisting on philosophical humility and avoiding scientific pride, it is faced with several problems, including 1 ignoring the referential and realist features of language, 2 confusing interpretation and reality, 3 eliminating the border between objectivity and subjectivity, 4 interfering of public and private life, and 5 ignoring the need of science, culture, technology and, in particular, politics, in philosophy. The authors try to show and analyze some elements of these problems.

    2006-03-29

    Professor Richard H. Dalitz passed away on January 13, 2006. He was almost 81 years old and his outstanding contributions are intimately connected to some of the major breakthroughs of the 20th century in particle and nuclear physics. These outstanding contributions go beyond the Dalitz Plot, Dalitz Pair and CDD poles that bear his name. He pioneered the theoretical study of strange baryon resonances, of baryon spectroscopy in the quark model, and of hypernuclei, to all of which he made lasting contributions. His formulation of the ''{theta} - {tau} puzzle'' led to the discovery that parity is not a symmetry of the weak interactions. A brief scientific evaluation of Dalitz's major contributions to particle and nuclear physics is hereby presented, followed by the first comprehensive list of his scientific publications, as assembled from several sources. The list is divided into two categories: the first, main part comprises Dalitz's research papers and reviews, including topics in the history of particle physics, biographies and reminescences; the second part lists book reviews, public lectures and obituaries authored by Dalitz, and books edited by him. This provides the first necessary step towards a more systematic research of the Dalitz heritage in modern physics.

    Full Text Available One of the most important natural resources we have is the soil and it is of great interest to the society to take care of them and not to pollute it. In the study of this issue, we are going to consider one of the most common forms of soil contamination due to an infiltration process. It is therefore that it is essential to address study and clearly understand this process by developing a mathematician model, which will be a representation of this physicist phenomenon. Then design and implement a computer program that simulates the infiltration of liquid pollutants in a given area. In this paper we will develop a mathematical model for two-dimensional infiltration in the saturated zone of porous media, based on the equation in nonlinear partial differential Richards Also, It will present a numerical solution through finite element method and first order This paper shows the computational implementation using a simulator that presents graphically the process of pollution afflicting the ground, exposed to certain pollutants, such as the oil spill in regions of eastern Ecuador, wastewater near industrial complexes, among others, over a certain period of time. Finally, this paper will allow for remedial studies in the case are already contaminated soils or preventive areas established as hazardous.

  8. Perbandingan antara Etika Jürgen Habermas dan Richard Rorty sebagai Prinsip Dasar Bertindak Manusia

    Dominique Rio Adiwijaya

    2010-10-01

    Full Text Available Ethics without doubt is an issue in every scientific field. Questions on ethics are not merely questions on the responsibility of one or two specific individuals, but rather as what have been defined accurately by Immanuel Kant in Critique of Practical Reason – as question of all humanity as a thinking creature and the freedom of choice on, “what should I do”. From Kant’s definition, we may infer that if human can not think and not free in determining their choice, it would be almost impossible to hope for moral responsibility. However this article does not mean to give a full and historical description on ethics, but a sketch on discourse of contemporary ethics which is represented by two famous philosophers, Jürgen Habermas from the tradition of  Critical Theory from Frankfurt School, dan Richard Rorty with “Neo-Pragmatism”. Habermas proposes “discourse ethics” while Rorty proposes ethic concepts through his “liberal-ironists”. It is hoped that the assembly of readers may gain an insight of the unavoidable ethics problems since every ethical position must be theory laden and the theory itself has historical characteristics (the characteristics, origin and historical context of the schools behind it. Therefore ethics is a neverending reflection although it has been started from 2500 years ago. Ethics invites us from specific sciences to enter its general discourse which unavoidably all-encompassing in its nature. 

  9. Staging Unincorporated Power: Richard Harding Davis and the Critique of Imperial News

    Directory of Open Access Journals (Sweden)

    Nirmal Trivedi

    2011-12-01

    Full Text Available This essay contextualizes the work of war correspondent Richard Harding Davis within an evolving “imperial news apparatus” that would culminate in his reporting of the Spanish-American War. Critics have conventionally framed Davis squarely within the imperial cause, associating him with his admirer Roosevelt and naval admiral Alfred T. Mahan. Contrary to readings of Davis as an apologist for US imperialism, Trivedi contends that Davis understood how US imperial power relied on an information apparatus to communicate to an increasingly media-conscious American public through culture, that is, via familiar narratives, symbols, and objects—what Trivedi calls “imperial news.” The essay follows Davis’s development from his fictional representation of the new war correspondent in “The Reporter Who Made Himself King” to his own war correspondence before and after the Spanish-American War as collected in the memoirs A Year from a Reporter’s Notebook (1897, Cuba in War Time (1897, and Notes of a War Correspondent (1912. Davis’s war correspondence and fictional work effectively stage US imperialism as “unincorporated power”: that is, as power reliant on a developing news-making apparatus that deploys particular discursive strategies to validate its political claims. This staging critiques strategies of US imperial sovereignty—specifically its “privatization of knowledge” and its promotion of the war correspondent as nothing more than a spectator and purveyor of massacres.

  10. The poetics of movement & translation – the case of Richard Zimler’s Strawberry Fields Forever

    2017-01-01

    Full Text Available The article focuses on a novel with a convoluted publishing history:Richard Zimler’s Strawberry Fields Forever. As a narrative about migrants, its publishing trajectory constitutes in itself a migration story. In 2011,Zimler planned to have a book coming out – Strawberry Fields Forever. In 2012, the book was paginated and ready to go to press. However, Arcadia Books went bankrupt, and the book remained unpublished. In 2011, José Lima translated the novel into European Portuguese. In a translator’s note,Lima discusses his translation as a form of ‘consented betrayal’. Using the resources of Portuguese, the translated text creates a surplus of meaning(s dependent on the target language and experience. Although hardly new, the surplus results, in this case, from a phenomenon of “overtranslatability”.This publishing history has been further compounded by the fact that the translated text was exported to Brazil, after being “translated” into Brazilian Portuguese. I would like to address the different forms of migration that this translation brings to the fore: (1 migration as story; (2 migration as form;(3 translation as transit; (4 text migration as a challenge to traditional concepts – as the “original” has never been published, the translations are the only extant texts.

  11. Alternative Ways of Challenging and Resisting in Richard Rodriguez’s Darling: A Spiritual Autobiography

    Directory of Open Access Journals (Sweden)

    Ibarrola-Armendariz Aitor

    2017-12-01

    Full Text Available There are several reasons why essayist Richard Rodriguez could be classified as a ‘minority’ writer; namely, his Mexican-American roots, his Catholic faith, and his self- declared homosexuality. However, readers who expect his writings to display the kind of attitudes and features that are common in works by other ‘minority’ authors are bound to be disappointed. The meditations that Rodriguez offers are far from clearly dividing the world between oppressors and oppressed or dominant and subaltern. As he sees it, ethnic, religious, class or sexual categories and divisions present further complications than those immediately apparent to the eye. Does this mean that Rodriguez fails to resist and challenge the dynamics he observes between different social groups? Or that his observations are complaisant rather than subversive? Not necessarily, since his essays are always a tribute to the possibilities of disagreement and defiance. My analysis of his latest collection of essays, Darling: A Spiritual Autobiography (2013, maps out and dissects the writing strategies that Rodriguez employs to generate dialogical forms of inquiry and resistance regarding such up-to-date topics as religious clashes (and commonalities, Gay rights (in relation to other Human Rights or how public spaces are being re-imagined in this global, digital era.

  12. Arctic observers: Richard King, monogenism and the historicisation of Inuit through travel narratives.

    Sera-Shriar, Efram

    2015-06-01

    In 1848 the ethnologist, surgeon and Arctic explorer Richard King (1810-1876) published a three-part series on Inuit in the Journal of the Ethnological Society of London. This series provided a detailed history of Inuit from the eleventh century to the early nineteenth century. It incorporated a mixture of King's personal observations from his experience travelling to the Arctic as a member of George Back's expedition (1833-1835), and the testimonies of other contemporary and historical actors who had written on the subject. The aim was to historicise Inuit through the use of travel reports and show persistent features among the race. King was a monogenist and his sensitive recasting of Inuit was influenced by his participation in a research community actively engaged in humanitarian and abolitionist causes. The physician and ethnologist Thomas Hodgkin (1798-1866) argued that King's research on Inuit was one of the best ethnological approaches to emulate and that it set the standard for the nascent discipline. If we are to take seriously Hodgkin's claim, we should look at how King constructed his depiction of Inuit. There is much to be gained by investigating the practices of nineteenth-century ethnologists because it strengthens our knowledge of the discipline's past and shows how modern understandings of races were formed.

    Full Text Available Albania, as well as a great part of the Balkan area in general, still suffers a lack of environmental studies especially in limnological research. The Dumre plateau, in Central Albania, is characterized by an extraordinary high number of karst lakes in a small geographic area. Despite their environmental peculiarity, very few biological data are to date available for these lakes, none on the zooplankton. For this reason, 15 water bodies located in the central area of the plateau were selected for a preliminary limnological survey carried out in the years 2008-2011. Neodiaptomus schmackeri (Poppe & Richard, 1892, a diaptomid calanoid copepod characterized by a South-Eastern Palearctic - Oriental distribution, and the most widely spread Neodiaptomus species in Asia, was found in 8 lakes of the Dumre area. This finding represents the first record of the species, and of the entire genus Neodiaptomus, for Europe. Several environmental variables were measured to characterize the lakes, and the co-occurring planktonic crustaceans were also identified. Taxonomical drawings and descriptions of the main morphological features of both sexes are herein provided in order to compare the Albanian populations of N. schmackeri with those of the native distribution area of the species. The possible causes which determined the occurrence of this non-indigenous species in several Dumre lakes are discussed.

  14. Some exact solutions to the Lighthill-Whitham-Richards-Payne traffic flow equations: II. Moderate congestion

    Infeld, E.; Rowlands, G.; Skorupski, A. A.

    2014-10-01

    We find a further class of exact solutions to the Lighthill-Whitham- Richards-Payne (LWRP) traffic flow equations. As before, using two consecutive Lagrangian transformations, a linearization is achieved. Next, depending on the initial density, we either obtain exact formulae for the dependence of the car density and velocity on x,t, or else, failing that, the same result in a parametric representation. The calculation always involves two possible factorizations of a consistency condition. Both must be considered. In physical terms, the lineup usually separates into two offshoots at different velocities. Each velocity soon becomes uniform. This outcome in many ways resembles not only that of Rowlands et al (2013 J. Phys. A: Math. Theor. 46 365202 (part I)) but also the two-soliton solution to the Korteweg-de Vries equation. This paper can be read independently of part I. This explains unavoidable repetitions. Possible uses of both papers in checking numerical codes are indicated. Since LWRP, numerous more elaborate models, including multiple lanes, traffic jams, tollgates, etc, abound in the literature. However, we present an exact solution. These are few and far between, other than found by inverse scattering. The literature for various models, including ours, is given. The methods used here and in part I may be useful in solving other problems, such as shallow water flow.

    2008-01-01

    Full Text Available La filosofía del lenguaje surge como la posibilitadora de la búsqueda de la verdad, función que ha acompañado siempre a la filosofía desde su aparición en Grecia. Con el lenguaje como protagonista, recordamos que la verdad ha estado ligada a aquel gracias a la herencia occidental de nuestro pensamiento. En este contexto, Richard Rorty nos plantea que la verdad tan solo está en las proposiciones, fruto de lenguajes elaborados por los hombres. Esta visión se opone a conceptos filosóficos como el esencialismo y el representacionalismo, y a creencias como la labor sacerdotal del filósofo, entre otras cosas. Pero la consecuencia más dura del pensamiento de nuestro autor es la consideración de la filosofía como un género literario más, en el cual la metaforicidad ha estado presente en sus discursos a pesar de su pretensión de objetividad y de erigirse como la develadora de la verdad.

Navy para-rescue men recovered the capsule housing the 3-man crew. The crew was taken to safety aboard the U.S.S. Hornet, where they were quartered in a Mobile Quarantine Facility (MQF). The Apollo 11 mission, the first manned lunar mission, launched from the Kennedy Space Center, Florida via the Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. The Saturn V vehicle was developed by the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun. Aboard were Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. Aldrin Jr., Lunar Module (LM) pilot. The CM, piloted by Michael Collins remained in a parking orbit around the Moon while the LM, named 'Eagle'', carrying astronauts Neil Armstrong and Edwin Aldrin, landed on the Moon. Armstrong was the first human to ever stand on the lunar surface, followed by Edwin (Buzz) Aldrin. During 2½ hours of surface exploration, the crew collected 47 pounds of lunar surface material for analysis back on Earth. With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished.

  19. Richard Posner summarizes: Legal realism as the response to the challenges of today

    2015-01-01

    Full Text Available Richard Posner, law professor at the University of Chicago and an American federal judge, one of the founders of economic analysis of law is among the greatest living representatives of contemporary American jurisprudence. This paper begins with the analysis of the influences of Posner's life on his theoretical orientation. Further on, the author shines a light on Posner's pragmatic, anti-formalistic approach and tendency to use economic analysis to explain judicial behavior. For that purpose, Posner uses ideas developed by American legal realism. Nevertheless, Posner distances himself from classical American legal realism, striving to create compromise between formalism and realism. Therefore, Posner takes centrist position, the position of 'balanced' realism. Though Posner tries to follow the middle way between extremes, in the light of contemporary challenges, most of all technological, he perceives the future in the realistic approach. The author claims that the Posner's pragmatic spirit, formed in his family and developed by his education and profession (his experience, had prevailing influence on his choice of legal realism in his late years. Particularly today, when life is much 'faster' than law, the judges are those who have to adapt the law to life (not only in common law countries. Therefore it seems that really 'the path forward is the path of realism'.

  20. Thinking in Pictures: John Wheeler, Richard Feynman and the Diagrammatic Approach to Problem Solving

    Science.gov (United States)

    Halpern, Paul

    While classical mechanics readily lends itself to sketches, many fields of modern physics, particularly quantum mechanics, quantum field theory, and general relativity, are notoriously hard to envision. Nevertheless, John Wheeler and Richard Feynman, who obtained his PhD under Wheeler, each insisted that diagrams were the most effective way to tackle modern physics questions as well. Beginning with Wheeler and Feynman's work together at Princeton, I'll show how the two influenced each other and encouraged each other's diagrammatic methods. I'll explore the influence on Feynman of not just Wheeler, but also of his first wife Arline, an aspiring artist. I'll describe how Feynman diagrams, introduced in the late 1940s, while first seen as `heretical' in the face of Bohr's complementarity, became standard, essential methods. I'll detail Wheeler's encouragement of his colleague Martin Kruskal's use of special diagrams to elucidate the properties of black holes. Finally, I'll show how each physicist supported art later in life: Wheeler helping to arrange the Putnam Collection of 20th century sculpture at Princeton and Feynman, in a kind of `second career,' becoming an artist himself.

    Full Text Available This study assessed the radiological health hazards to various body organs of workers working within Transnet Precinct in Richards Bay in Kwazulu-Natal, South Africa due to radionuclide content of mineral ores often stored within the facility. Thirty samples were collected from five mineral ores (rock phosphate, rutile, zircon, coal and hematite and analyzed for 238U, 234U, 226Ra, 210Pb, 235U, 232Th, 228Ra, 228Th and 40K using delayed neutron activation analysis and low energy gamma spectroscopy. Rutile was found to be the most radioactive mineral ore within the facility with 210Pb concentration of 759.00 ± 106.00 Bq·kg−1. Effective annual dose rate in (mSv·y−1 delivered to different organs of the body: testes, bone marrow, whole body, lungs and ovaries from mineral ores were such that dose from mineral ores decreased in the order coal > rutile > rock phosphate > hematite > zircon. The organs with the highest received dose rate were the testes and this received dose was from coal. However, all of the calculated absorbed dose rates to organs of the body were below the maximum permissible safety limits.

  3. Poets/Trump/Philosophers: Reflections on Richard Rorty’s Liberalism, Ten Years after His Death

    2017-08-01

    Full Text Available Starting with a prescient 1998 quote on the impending decline of US liberal democracy into right-wing, strong-man-based demagogy, this paper outlines Richard Rorty’s political philosophy, which I believe can help us understand perplexing political trends in today’s political reality well beyond the US alone. Specifically, I tackle three key-terms encapsulating the thrust of Rorty’s political philosophy, i.e. “liberalism of fear”, “bourgeois” and “postmodernism”. Also, I address a contraposition that explains how Rorty would approach and attempt to defend liberal democracy from contemporary right-wing, strong-man-based degenerations, namely the priority of “poetry” over “philosophy”. Essentially, if one wishes to win in the political arena, she must be armed with the most effective rhetorical weaponry, however good, solid and well-argued her political views may be. Finally, some remarks are offered on the role that “philosophy” can still play within the same arena.

  4. Against the Nihilism of Suffering and Death: Richard E. K. Kim and His Works

    Full Text Available This article examines the life and works of Richard E. K. Kim (1932–2009, a first-generation Korean diasporic writer in the United States. It focuses on how Kim struggled to overcome the nihilism of suffering and death that derived from colonialism and the Korean War through his literary works. Kim witnessed firsthand these two major historical events, which caused irrevocable psychological and physical damage to many people of his generation. In his autobiographical fiction, he conveys painful memories of the events by reviving the voices of people in that era. What his works offer us goes beyond vivid memories of the past, however; they also present the power of forgiveness as a condition to overcome the nihilism of suffering and death. Remembrance and forgiveness are, therefore, two major thematic pillars of his works that enable us to connect to these difficult and traumatic times. These themes are portrayed in such a gripping way mainly because Kim tried to maintain a certain distance—an emotional and linguistic distance—from the familiar, in order to elucidate the reality of the human condition: an ontological position of the exile from which he produced his works. This article argues that Kim’s works provide us the possibility to transcend the nihilism of historical trauma through articulating the meaning of remembrance and forgiveness from his self-assumed position of exile.

  5. Unreliability and the Animal Narrator in Richard Adams’s The Plague Dogs

    2017-03-01

    Full Text Available Richard Adams’s talking animal story The Plague Dogs (1978, with its deeply genre-atypical mode of narration, offers a multiplicity of avenues to explore the literary animal as animal. The story draws much of its power from the psychological complexity and related unreliability of both canine narrators, two research lab escapees gone feral. Both the terrier Snitter and the black mongrel Rowf are mentally ill and experience a highly subjective, part-fantastic world. In episodes of zero focalization, a sarcastic voice comments on the plot from the off, aggressively attacking a thoroughly anthropocentric superstructure the protagonists themselves are oblivious of, and presenting all that is normally constructed as “rational” in the implied reader’s world as a carnivalesque farce. Combining these equally unreliable narratives, The Plague Dogs creates a unique mixture of what Phelan (2007 calls “estranging” and “bonding” unreliability and brings to light the devastating consequences of anthropocentrism. The Plague Dogs not only defamiliarizes a genre usually committed to conventional means of storytelling, but the dominant Western conception of the status of animals in the world, showing that once we start to read the animal as animal, this sets into motion an avalanche of other concepts in need of re-reading, among them the very ones making up the fundamental pillars of Western societies’ anthropocentric self-conception.

  6. “This World Is Not My Home”: Richard Mouw and Christian Nationalism

    Full Text Available American evangelicalism has often been punctuated by dual commitments to the United States and to God. Those commitments were strongest within politically conservative evangelicalism. Though representing a solid majority among professing evangelicals, conservatives could not speak for the movement as a whole. Politically progressive evangelicals, beginning in the 1960s, formed a dissenting opinion of the post-World War II revival of Christian nationalism. They dared to challenge American action abroad, noticeably during the Vietnam War. Their critique of Christian nationalism and conservative evangelicals’ close ties to the Republican Party led them to seek refuge in either progressive policies or the Democratic Party. A third, underexplored subgroup of evangelicalism rooted in reformed theology becomes important to consider in this regard. These reformed evangelicals sought to contextualize nationalism in biblical rather than partisan or political terms. This goal is championed well by Richard Mouw, resulting in a nuanced look at evangelical Christians’ difficult dual role as both citizens of the Kingdom of God and the United States.

  7. Who invented the dichotomous key? Richard Waller's watercolors of the herbs of Britain.

    2011-12-01

    On 27 March 1689, Richard Waller, Fellow and Secretary of the Royal Society presented his "Tables of the English Herbs reduced to such an order, as to find the name of them by their external figures and shapes" to his assembled colleagues at a meeting of the Royal Society. These tables were developed for the novice by being color images, composed in pencil and watercolor, of selected plants and their distinguishing characteristics. The botanical watercolors for the tables are now a Turning-the-Pages document online on the website of the Royal Society. However, for the past 320 years, the scientific context for the creation of these outstanding botanical watercolors has remained obscure. These tables were developed by Waller as an image-based dichotomous key, pre-dating by almost 100 years the text-based dichotomous keys in the first edition of Flora Française (1778) by Jean Baptiste Lamarck, who is generally given priority for the development of the dichotomous key. How these large folio images were arranged to illustrate a dichotomous key is unknown, but an arrangement based on Waller's description is illustrated here as leaf-ordering for the separate hierarchical clusters (tables). Although only 24 species of watercolored dicot herbs out of a total of 65 in the set of watercolors (the others being monocots) are used in these tables, they are a "proof of concept", serving as models upon which a method is based, that of using a key composed of dichotomous choices for aiding identification.

  8. On the continuum-scale simulation of gravity-driven fingers with hysteretic Richards equation: Trucation error induced numerical artifacts

    Energy Technology Data Exchange (ETDEWEB)

    ELIASSI,MEHDI; GLASS JR.,ROBERT J.

    2000-03-08

    The authors consider the ability of the numerical solution of Richards equation to model gravity-driven fingers. Although gravity-driven fingers can be easily simulated using a partial downwind averaging method, they find the fingers are purely artificial, generated by the combined effects of truncation error induced oscillations and capillary hysteresis. Since Richards equation can only yield a monotonic solution for standard constitutive relations and constant flux boundary conditions, it is not the valid governing equation to model gravity-driven fingers, and therefore is also suspect for unsaturated flow in initially dry, highly nonlinear, and hysteretic media where these fingers occur. However, analysis of truncation error at the wetting front for the partial downwind method suggests the required mathematical behavior of a more comprehensive and physically based modeling approach for this region of parameter space.

  11. A Few Remarks on the Poetics of Turbulence in Richard Powers’ Operation Wandering Soul

    Jean-Yves Pellegrin

    2010-02-01

    Full Text Available Dans le roman de Richard Powers Operation Wandering Soul, la linéarité conventionnelle du récit cède le pas à une forme de discontinuité et de circularité qui évoque le mouvement imprévisible d’une turbulence. On propose de montrer ici que cette turbulence met en œuvre une nouvelle manière d’écrire et de lire les récits. Dans le roman, la turbulence apparaît toujours sous l’aspect d’une force désorganisatrice qu’il faut maîtriser, un bruit qui doit être supprimé. Cet impératif, témoin des aspirations du récit au sens et à la clôture, peut se concevoir comme l’indice de la manière dont l’ordre narratif s’efforce de soumettre toute turbulence en dissimulant son chaos sous une linéarité de façade et des dénouements postiches. Cette activité transforme le récit (et le type de lecture qu’elle induit en une sorte d’eschatologie dont Operation Wandering Soul dénonce le mensonge et la fuite en avant. Pour en combattre les effets néfastes, le roman s’emploie à perturber l’ordre narratif et à bousculer nos habitudes de lecture ; il se fait texte turbulent en conformant sa structure la plus intime à celle des systèmes non linéaires.In Richard Powers’ Operation Wandering Soul, the conventional linearity of narrative gives way to a type of discontinuity and circularity that is reminiscent of the unpredictable movement of turbulent flows. This paper suggests that such turbulence enacts a new way of writing and reading narrative. Turbulence is always described in the novel as a disruptive force that must be checked or a noise that must be silenced. This imperative, which testifies to narrative’s desire for closure and meaning, may be construed as an index of the way narrative order attempts to subdue all turbulence by covering up its proliferating chaos with perfunctory linearity and cosmetic endings. Such activity turns narrative—and the type of reading it encourages—into some kind of

  12. Staging Unincorporated Power: Richard Harding Davis and the Critique of Imperial News

    Directory of Open Access Journals (Sweden)

    Nirmal Trivedi

    2011-12-01

    Full Text Available This essay contextualizes the work of war correspondent Richard Harding Davis within an evolving “imperial news apparatus” that would culminate in his reporting of the Spanish-American War. Critics have conventionally framed Davis squarely within the imperial cause, associating him with his admirer Roosevelt and naval admiral Alfred T. Mahan. Contrary to readings of Davis as an apologist for US imperialism, Trivedi contends that Davis understood how US imperial power relied on an information apparatus to communicate to an increasingly media-conscious American public through culture, that is, via familiar narratives, symbols, and objects—what Trivedi calls “imperial news.” The essay follows Davis’s development from his fictional representation of the new war correspondent in “The Reporter Who Made Himself King” to his own war correspondence before and after the Spanish-American War as collected in the memoirs A Year from a Reporter’s Notebook (1897, Cuba in War Time (1897, and Notes of a War Correspondent (1912. Davis’s war correspondence and fictional work effectively stage US imperialism as “unincorporated power”: that is, as power reliant on a developing news-making apparatus that deploys particular discursive strategies to validate its political claims. This staging critiques strategies of US imperial sovereignty—specifically its “privatization of knowledge” and its promotion of the war correspondent as nothing more than a spectator and purveyor of massacres.

  13. The Effect of Richard Wagner's Music and Beliefs on Hitler's Ideology

    2016-09-01

    Full Text Available The Holocaust will always be remembered as one of the most horrific and evil events in all of history. One question that has been so pervasive in regards to this historical event is the question of why. Why exactly did Hitler massacre the Jewish people? Why did he come to the conclusion that the Jews were somehow lesser than him, and that it was okay to kill them? What and who were his influences and how did they help form Hitler’s opinions leading up to the Holocaust? Although more than one situation or person influenced Hitler, I believe that one man in particular really helped contribute to Hitler’s ideas, especially about the Jewish people. This man is the famous musician Richard Wagner. While musicologists admit that Wagner was a musical genius, one aspect of his career that is hard to ignore is his strong antisemitism. In addition to speaking about his hatred for the Jews, he also wrote about it in his music, making it hard to glance over. Hitler had been close to the Wagner family, and had an obsessive, cult-like infatuation with Wagner’s music beginning in his childhood. This infatuation with Wagner’s music and his closeness to his later family helped facilitate and solidify his negative views about the Jewish people. In this paper I will explore the antisemitism that is within Wagner’s music and writing, and then I will discuss how Wagner’s antisemitism helped inform, influence, and shape Hitler’s ideas, indirectly assisting in the propagation of the Holocaust.

  14. Therapeutic micro-environments in the Edgelands: A thematic analysis of Richard Mabey's The Unofficial Countryside.

    2015-05-01

    The concept of therapeutic landscapes, as introduced by Gesler, has had a significant impact on what has become a reformed geography (or geographies) of health. Research in this field has developed the number and type of sites that have been characterised as therapeutic landscapes. A wide range of environments have now been explored through the analytical lens of the 'therapeutic landscape'. This research further expands current descriptions of such environments by exploring Edgelands as therapeutic micro landscapes. Edgelands refer to the neglected and routinely ignored interfacial zone between urban and rural that are a routine characteristic of the urban fringe resulting from dynamic cycles of urban development and decay. Using a hybrid method of thematic analysis incorporating both inductive and deductive approaches, this research explores Richard Mabey's seminal work on this topic, The Unofficial Countryside. Previous examinations of the features of therapeutic environments are therefore scrutinised to explore both scale and the possibility of further extending the kind of environments that may be described as therapeutic to include Edgelands. This approach is informed, in part, by principles of mindfulness, a historically Eastern, but increasingly Western approach to exploring oneself and the environment. This research identifies that these overlooked and neglected landscapes are in fact vibrant, resilient and enthralling environments teeming with life, renewal and re-birth. Examination reveals that there are three crucial outcomes of this research. The first relates to the issue of scale. Mabey's book provides evidence of the importance of micro environments in providing a therapeutic environmental focus. Secondly, this research explores the potential of mindfulness as an approach in Geography. Lastly, this research also identifies Edgelands as therapeutic sites and calls for an increased understanding and appreciation of their potential. Copyright © 2014

  15. An experimental 'Life' for an experimental life: Richard Waller's biography of Robert Hooke (1705).

    Moxham, Noah

    2016-03-01

    Richard Waller's 'Life of Dr Robert Hooke', prefixed to his edition of Hooke's Posthumous Works (1705), is an important source for the life of one of the most eminent members of the early Royal Society. It also has the distinction of being one of the earliest biographies of a man of science to be published in English. I argue that it is in fact the first biography to embrace the subject's natural-philosophical work as the centre of his life, and I investigate Waller's reasons for adopting this strategy and his struggle with the problem of how to represent an early experimental philosopher in print. I suggest that Waller eschews the 'Christian philosopher' tradition of contemporary biography - partly because of the unusually diverse and fragmentary nature of Hooke's intellectual output - and draws instead upon the structure of the Royal Society's archive as a means of organizing and understanding Hooke's life. The most quoted phrase from Waller's biography is that Hooke became 'to a crime close and reserved' in later life; this essay argues that Waller's biographical sketch was fashioned in order to undo the effects of that reserve. In modelling his approach very closely on the structure of the society's records he was principally concerned with making Hooke's work and biography accessible, intelligible and useful to the fellowship in a context familiar to them, a context which had provided the institutional framework for most of Hooke's adult life. I argue that Waller's 'Life' was also intended to make the largest claims for Hooke's intellectual standing that the author dared in the context of the enmity between Hooke and Isaac Newton once the latter became president of the Royal Society. However, I also adduce fresh manuscript evidence that Waller actually compiled, but did not publish, a defence of Hooke's claim to have discovered the inverse square law of gravity, allowing us to glimpse a much more assertive biography of Hooke than the published version.

    Body sway while maintaining an upright quiet stance reflects an active process of balance based on the integration of visual, vestibular, somatosensory, and proprioceptive inputs. Richard Serra's Promenade sculpture featured in the 2008 Monumenta exhibition at the Grand Palais in Paris, France is herein hypothesized to have stimulated the body's vertical and longitudinal axes as it showcased five monumental rectangular solids pitched at a 1.69(°) angle. Using computerized dynamic posturography we measured the body sway of 23 visitors when fixating a cross, or when observing the artwork (fixating it or actively exploring it with eye movements) before and after walking around and alongside the sculpture (i.e., before and after a promenade). A first fixation at the sculpture increased medio-lateral stability (in terms of spectral power of body sway). Eye movement exploration in the depth of the sculpture increased antero-posterior stability [in terms of spectral power and canceling time (CT) of body sway] at the expense of medio-lateral stability (in terms of CT). Moreover, a medio-lateral instability associated with eye movement exploration before the promenade (in terms of body sway sensu stricto) was canceled after the promenade. Finally, the overall medio-lateral stability (in terms of spectral power) increased after the promenade. Fourteen additional visitors were asked to stand in a dark room and adjust a luminous line to what they considered to be the earth-vertical axis. The promenade executed within the sculpted environment afforded by Serra's monumental statuary works resulted in significantly improved performances on the subjective visual vertical test. We attribute these effects to the sculpted environment provided by the exhibition which may have acted as a kind of physiologic "training ground" thereby improving the visitors' overall sense of visual perspective, equilibrium, and gravity.

  17. An Enlightenment proposal for music therapy: Richard Brocklesby on music, spirit, and the passions.

    Gouk, Penelope

    2015-01-01

    In 1749, the London physician Richard Brocklesby (1722-1797) published his Reflections on Antient [sic] and Modern Musick, an essay that not only sought to compare these practices in terms of their effects, but also to gather evidence supporting the use of music in treating mania and other mental diseases. As might be expected, Brocklesby's discussion of music therapy has already received attention by authors looking back to the origins of this practice, not least because he offers an account of a successful musical cure that took place in his own time (Rorke, 2001). My chapter, however, seeks to broaden the discussion of the Reflections, in order to show how Brocklesby's projected musical cures fit into his larger worldview, one that was influenced as much by Plato and other ancient philosophers as it was by modern thinkers such as Isaac Newton and his followers. Brocklesby's argument was essentially that music acted as a link between the mind and body and therefore could restore their intrinsic harmony, a connection that was mediated by the animal spirits, which also served as the vehicle of the passions. The movements and proportions of music could arouse or quell the passions by their effect on these (imaginary) spirits, which flowed through the nerves and brain and acted as the agent for the mind or soul. I show how his account of music in antiquity led him to reflect on the way that music was perceived and responded to in his own time, both as a stimulus to mental and bodily action, and as a source of esthetic pleasure through the cultivation of musical taste. © 2015 Elsevier B.V.

    Wark, Colin; Galliher, John F

    2010-05-01

    This research focuses on the events leading to the 1968 U.S. federal prohibition of psilocybin. It is a study of duelling moral entrepreneurs-Timothy Leary and Richard Alpert vs. the Harvard University Administration. The goal is to show how the primary active compound in an ostensibly harmless fungus (the psilocybin mushroom) became controversial in less than a decade. We used books, newspapers, magazine articles and previously unpublished materials (including documents from the Harvard Archives) to analyze Leary and Alpert's lives and careers through the early 1970s. The prohibition of psilocybin in the U.S. was largely a product of Leary and Alpert's involvement in the "Harvard drug scandal" and their transformation from Harvard professors to countercultural icons. They tested the substance on a variety of human subjects and in doing so piqued the interest of Harvard undergraduates while drawing condemnation from other faculty and Harvard administrators. This case is theoretically interesting because unlike most illegal drugs, psilocybin was never linked to a threatening minority group, but to some of the nation's most privileged youth. The Harvard administrators were not really moral entrepreneurs but Leary and Alpert clearly were. Although they were far from being prohibitionists, they were self-righteous crusaders on different but equally holy missions for the good of young and minority Americans. Ironically, due to their successes the possession of psilocybin was criminalized under United States federal law in 1968 (Pub. L. No. 90-639, Stat. 1361 1968 and Boire, 2002). This case study demonstrates that crusaders can be successful in changing culture even when laws are passed in futile attempts to control their behaviour, just as Leary predicted.

Although Henry and Kearney both develop a Christian theology rooted in this Husserlian inheritance, their explication of the truths Christianity asserts is strikingly different.

Pour nous, la différence entre eux est de type textuel, c’est à dire qu’elle dépend de l’analyse qu’ils font de la Sainte Écriture.Questo articolo si propone di riprendere il contenuto dei testi Io sono la verità di Michel Henry e The God Who May Be di Richard Kearney, nei quali i rispettivi autori analizzano la critica husserliana dell'epistemologia di Kant. Sebbene entrambi sviluppano una "teologia" cristiana radicata in questa eredità husserliana, la loro spiegazione delle verità cristiane è alquanto differente. Per noi, la differenza tra essi è di tipo testuale, vale a dire che dipende dall'analisi che essi fanno del testo biblico.

    Richards Bay, on the northern KwaZulu-Natal coast, is the largest coal exporting port in South Africa. The coal is stored at the Richards Bay Coal Terminal (RBCT) prior to export. Dust from coal operations is a major problem in the Richards Bay area. In this study, we tested the hypothesis that coal dust adversely affects photosynthetic performance of Avicennia marina (Forssk.) Vierh., the dominant mangrove species in the harbour. Photosynthetic performance was determined on 10 trees by measuring carbon dioxide uptake and chlorophyll fluorescence parameters at two elevation sites and on upper and lower leaf surfaces that were covered or uncovered with coal dust. Measurements were made on five clear, sunny days at saturating light (> 1000 {mu}mol m{sup -2} s{sup -1}) and high temperature (28-30{sup o}C). Coal dust significantly reduced carbon dioxide exchange of upper and lower leaf surfaces by 17-39%, the reduction being generally greater on the lower leaf surface that is covered by a dense mat of trichomes and salt glands. The reduction in carbon dioxide exchange by coal dust was higher at the high elevation site that supported isolated dwarfed trees. The chlorophyll fluorescence data indicated that leaves coated with dust exhibited significantly lower photosystem II (PS II) quantum yield, lower electron transport rate (ETR) through PSII and reduced quantum efficiency of PSII (F{sub v}/F{sub m}). The chlorophyll fluorescence data supported the gas exchange measurements and are consistent with reduced photosynthetic performance of leaves coated with coal dust.

    This is a special issue of Genetica that has its origins in a symposium held in honor of Richard G. Harrison at Ithaca, New York on July 22–23. Former students of Rick Harrison organized the symposium and most of the speakers were former students, as well. The quality and breadth of the talks were a testament to Rick’s influence as a thinker, synthesizer, and mentor and it is only appropriate to reflect on Rick’s contributions to the fields of evolutionary ecology, systematics, and genetics in this preface to the symposium articles.

    Full Text Available This text presents the theatrical act as a passage, based on the observation of the actions of Thomas Richards and Mario Biagini that belong to a work protocol left by Jerzy Grotowski. This is the moment in which art as a vehicle, as Peter Brook wrote, merges with the art of the encounter. It is also the moment in which the experience transmitted by theatre causes the disappearance of boundaries and limits between scene, actor and spectator. The art of the encounter corresponds, then, to the inclusion of the spectator into the theatrical process which favours a return of the presence of oneself, the disappearance of self-estrangement.

    A total of eight commercial spaceflight participants have launched to the International Space Station (ISS) on Soyuz vehicles. Based on an older mean age compared to career astronauts and an increased prevalence of medical conditions, spaceflight participants have provided the opportunity to learn about the effect of space travel on crewmembers with medical problems. The 12-d Soyuz TMA-13/12 ISS flight of spaceflight participant Richard Garriott included medical factors that required preflight intervention, risk mitigation strategies, and provided the opportunity for medical study on-orbit. Equally important, Mr. Garriott conducted extensive medical, scientific, and educational payload operations during the flight. These included 7 medical experiments and a total of 15 scientific projects such as protein crystal growth, Earth observations/photography, educational projects with schools, and amateur radio. The medical studies included the effect of microgravity on immune function, sleep, bone loss, corneal refractive surgery, low back pain, motion perception, and intraocular pressure. The overall mission success resulted from non-bureaucratic agility in mission planning, cooperation with investigators from NASA, ISS, International Partners, and the Korean Aerospace Research Institute, in-flight support and leadership from a team with spaceflight and Capcom experience, and overall mission support from the ISS program. This article focuses on science opportunities that suborbital and orbital spaceflight participant flights offer and suggests that the science program on Richard Garriott's flight be considered a model for future orbital and suborbital missions. The medical challenges are presented in a companion article.

In 1947 Jean Vilar opened the first Avignon Festival with an ascetic, charismatic eponymous hero who came to an inner knowledge of himself in his bare prison cell; in 1982 Ariane Mnouchkine offered a splendid visual display by transposing the play into the kabuki tradition; this offered the audience breath-taking and dynamic tableaux of elaborate court ceremonies and rebellious lords.At such a distance in time, the English medieval code of honour was dealt with according to completely different theatrical principles of ethics and aesthetics, mirroring the changes in perspective within French society.

    This article presents a new mixed integer programming formulation of the traffic density estimation problem in highways modeled by the Lighthill Whitham Richards equation. We first present an equivalent formulation of the problem using an Hamilton-Jacobi equation. Then, using a semi-analytic formula, we show that the model constraints resulting from the Hamilton-Jacobi equation result in linear constraints, albeit with unknown integers. We then pose the problem of estimating the density at the initial time given incomplete and inaccurate traffic data as a Mixed Integer Program. We then present a numerical implementation of the method using experimental flow and probe data obtained during Mobile Century experiment. © 2012 IEEE.

Regarding the former topic, the goal will be to highlight the ambiguity of those Owen’s remarks, and concerning the latter topic what is looked for is to show that, when he explained his transmutationist thesis, Owen didn’t go beyond a pious theistic evolutionism, without postulating any mechanism of evolutionary change and remaining faithful to Design Theology praised by Paley.

  16. The relationship between ethics and human rights in the thought of Richard Rorty

    2014-04-01

    Full Text Available In general, two theories or school of thoughts had been prevailed in modern moral philosophies until recently. Ethical school of thought of "task-oriented", in which the emphasis is on the nature of the action. At first, this school of thought was considered by Immanuel Kant. Accordingly, doing or will to do every action should be such that become a universal moral law. In contrast, another ethical school of thought known as "utilitarianism ethics" was introduced by Jeremy Bentham and John Stuart Mill. Here, we give priority to those moral actions that can bring the greatest happiness for most people. In three or four recent decades, coinciding with the linguistic and cognitive turn, which has become known as the transition from positivism to post-positivism, another challenge has been raised in discussing philosophy of ethics by Richard Rorty which is related to his claim regarding the requirements of the current multiple world. This claim can make a new relation between morality and human rights. Hence, the main hypothesis of this paper is to clarify the point that Rorty has raised his claim by combining the theory of pragmatism and postmodern Ethics. To prove this hypothesis, this article has been set in two sections, in the first section in order to become familiar with Rorty's creed-breaker thought, the foundations of the philosophy of ethics is discussed. In the second section and under the discussion of ethics based on the rights of human, some of its characteristics will be analyzed. This article has been prepared by a descriptive method through the content analysis of various works of Rorty. Theoretical support for this article is a critical-normative approach. به طور کلی در فلسفه‌های اخلاق مدرن تا این اواخر دو نگره یا مکتب حاکم بوده است. مکتب اخلاق «وظیفه‌گرا»که در آن بر ماهیت کنش تأکید می‌شود. این مکتب ابتدا

  20. Closure of the Richard underground repository for low and intermediate level radioactive waste - application of the hydraulic cage concept

    2006-01-01

    The Richard Repository, in the North of the Czech Republic, is a near surface underground repository for low and intermediate level radioactive waste of institutional origin. Disposal has been carried out here since the mid nineteen-sixties, leading to a current inventory of about 1E+15 Bq. In 2003, the Czech Radioactive Waste Repository Authority (RAWRA) launched a Phare project aimed at reducing burden from past practices during the first phase of the Richard repository operation and at improving its overall long term safety. The contract for this project was awarded to DBE TECHNOLOGY GmbH. When reviewing the preliminary closure concept and the related safety assessment prepared by RAWRA, it became clear that the existing concept had deficits in regard to potential radiological exposure after closure of the repository. To remediate such hazards, DBE TECHNOLOGY GmbH developed a new concept for the closure of individual waste chambers. The main technological element of this concept is the installation of an additional engineered barrier called hydraulic cage around the waste chambers. This cage prevents the development of advective flow through the waste/concrete body within the backfilled chambers and thereby advective transport of radionuclides. An important advantage of the new closure concept is that fact that the safety against potential radiological impact originating from waste inside a closed chamber is achieved directly and does not rely on any additional measures connected with the future closure of the repository as a whole. After consulting the competent Czech authorities RAWRA decided to follow the hydraulic cage concept for the planned realization of the closure of a certain chamber system within the mine. During further execution of the project a detailed plan for this closure work was elaborated to a degree of detail, which allowed its direct technical realization, which started at the beginning of 2006. By October 2006, the first segment of the

    Full Text Available This paper investigates Australian author Richard Flanagan’s novel, The Narrow Road to the Deep North, and attempts to clarify the reason why Flanagan chose this title, which is linked to the travel writings of the Japanese author Matsuo Basho, for his novel. The novel focuses on the central character’s prisoner of war experience on the Thai-Burma Death Railway during World War II, and depicts the POW camp as well as cruel Japanese behaviour and atrocities in a realistic way. The work seems to provide a postcolonial framework in the sense that there is a colonial and postcolonial relationship between the colonizer, and the colonized. However, in this novel, the colonizer is Eastern, and the colonized is Western, and this fact reverses postcolonial theory which postulates a structure in which the colonizer is usually considered as Western and the colonized, Eastern. Postcolonial theory, thus, cannot be applied in this novel, which attempts to fuse the two opposites, the Western view and the Eastern view, through the work of the Japanese poet. As a result, Flanagan, in writing The Narrow Road to the Deep North, goes beyond being a postcolonial writer to become a writer in a globalizing age.

    Full Text Available O texto discute o sentido polémico do “regresso” a África que Richard Wright inscreve em Black Power e a forma como a narrativa da viagem subverte a “Middle Passage”. O sujeito narrativo orienta o leitor através de uma incursão pessoal nos muitos sentidos da modernidade e desdobra a noção de “destino comum”, já apontada em 12 Million Black Voices. Contudo, qualquer sentido de comunidade é aqui necessariamente ambíguo, por estar sempre relacionado com questões de raça e identidade. Black Power é uma narrativa importante para o conceito de modernidade e assinala uma mudança significativa na produção literária de Wright para uma vertente não-ficcional. Esta segunda fase da sua obra contém, no entanto, um paradoxo crucial: enquanto se volta para o exterior, para o mundo mais global, Wright tenta, simultaneamente, inscrever-se como referência sobre o locus do qual nunca poderia demarcar‑se: África. Em Black Power, a duboisiana “color line” desdobra‑se em múltiplas dimensões.

    Water is a complex source of imagination, dreams and rituals, where cultural differences ebb and flow, where a plethora of meanings and interpretations interlink and wash over one another. Water has an ambivalent character as stated in most of the ancient cosmogonies and in the Epic of Gilgamesh. Water's composition was discovered by the London scientist Henry Cavendish in about 1781. Although it is an apparently simple molecule (H2O), it has a highly complex and anomalous character. The anomalous properties of water are those where the behavior of liquid water is quite different from what is found with other liquids. As often stated, life depends indeed on these anomalous properties of water. Notably there are 12 phase, 22 density, 12 material, 11 thermodynamic and 9 physical anomalies. A powerful look into the water molecule was given by Nobel Prize recipient Richard P. Feynman as published in Six easy pieces. A look into the most recent quest for more knowledge about water leads us to the concept of pathological science. The cases of "polywater" and "the memory of water" are indeed paradigmatic episodes of fraudulent research published in journals with high impact factors. In conclusion, men came out of water engineered to handle water, and water greatly affects mythology and philosophy and is a strong presence in the arts and science.

    Richard Repository is a near surface underground repository for low and intermediate level radioactive waste of institutional origin. In the course of a joint Phare Project carried out together with the repository operator, the Czech Radioactive Waste Repository Authority (RAWRA), DBE Technology developed a new concept for the closure of individual waste chambers. Main technological element of this concept is the installation of a hydraulic cage around the waste chambers by attaching a gravel layer to all sides of the chamber. This hydraulic cage will prevent the development of advective flow through the waste/concrete body within the backfilled chambers by eliminating the pressure gradient as driving force for such a flow. Thus the transport of radionuclides will be restricted to diffusive fluxes, which results in a considerable decrease of potential radiological impact. In the course of the project the closure of a certain chamber system within the mine was planned up to a grade of detail, which allowed its direct realization as a pilot closure study, which started in the beginning of 2006.

    This Basic Award allowed for the funding of student scholarships to the Richard Tapia Celebration of Diversity in Computing Conference which took place in Washington, D.C. from February 7-10, 2013. The conference was the seventh in a series and included a stellar array of invited speakers, compelling panel discussions, a student poster competition, a daylong Doctoral Consortium, a session featuring a choice of attractions unique to Washington, D.C., a gala banquet and dance, and many exciting networking opportunities. The conference created a welcoming environment for STEM students, especially underrepresented minority and female students, who were provided the highest quality of learning, networking, and social experiences to empower their educational experience and enhance their ability to succeed with a rigorous STEM degree. The networking and mentoring opportunities available at the conference were also designed to empower students to succeed in STEM careers and ultimately serve in leadership in industry and the professoriate. A key step in attracting underrepresented students into STEM fields and paving the way for their success in influential positions is to create a nurturing and supportive network and community for them to rely upon. It is also critical to educate leaders in corporations, government and academia about the benefits to be gained from increasing the percentage of STEM professionals from underrepresented groups. To this end, The Tapia Conference serves both functions, as it connects STEM students with STEM professionals, leaders, and academics who share the vision of a STEM workforce and community that is truly representative of the community in which we live.

  9. Leo Tolstoy, Mikhail Artsybashev, and Richard Wagner: About One Case of Polemics in Tolstoy’s The Circle of Reading

    Directory of Open Access Journals (Sweden)

    Anastasia A. Tulyakova

    2017-12-01

    Full Text Available The article deals with a case from the creative history of Leo Tolstoy’s The Circle of Reading (1908, when Tolstoy included the revised story of Guy de Maupassant’s Le Port under the title “Sisters” in the second edition of the book. The author proves that the reason for Tolstoy’s decision was his polemic with “saninstvo” as one of the most fashionable ethical trends of the first decade of the 1900s. The key component of Sanin’s behavior and hedonistic philosophy in Mikhail Artsybashev’s novel was incest. Maupassant’s novella is based on the same plot. On the basis of Tolstoy’s nonfictional texts of the 1890s, including the treatise What Is Art? (1898, the article reconstructs the writer’s view on the forms and boundaries of the representation of incest in Richard Wagner’s operas and in Friedrich Nietzsche’s philosophy, with which Tolstoy also polemicized and in connection with which he stated the ethical potential of art and its permissiveness. From this perspective, Tolstoy’s reaction to Artsybashev’s novel, combining the motives of incest and extreme individualism, turns out to be a new phase of the old dispute. Tolstoy included the story “Sisters” in the second edition of The Circle of Reading as a response to the philosophy of “saninstvo.” Thus, Tolstoy’s collection of wise thoughts can be considered not only as didactic, but also as a polemical text, and deeply rooted in the ideological context of the 1890s‒1900s.

    U.S. President Richard Milhous Nixon (center), is saluted by the honor guard of flight deck crewmen when he arrives aboard the U.S.S. Hornet, prime recovery ship for the Apollo 11 mission, to watch recovery operations and welcome the astronauts home. The recovery operation took place in the Pacific Ocean where Navy para-rescue men recovered the capsule housing the 3-man Apollo 11 crew. The crew was airlifted to safety aboard the U.S.S. Hornet, where they were quartered in a Mobile Quarantine Facility (MQF) for 21 days following the mission. The Apollo 11 mission, the first manned lunar mission, launched from the Kennedy Space Center, Florida via the Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. Aboard were Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. Aldrin Jr., Lunar Module (LM) pilot. The CM, piloted by Michael Collins remained in a parking orbit around the Moon while the LM, named 'Eagle'', carrying astronauts Neil Armstrong and Edwin Aldrin, landed on the Moon. Armstrong was the first human to ever stand on the lunar surface, followed by Edwin (Buzz) Aldrin. During 2½ hours of surface exploration, the crew collected 47 pounds of lunar surface material for analysis back on Earth. With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished. The Saturn V vehicle was developed by the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun.

    Body sway while maintaining an upright quiet stance reflects an active process of balance based on the integration of visual, vestibular, somatosensory, and proprioceptive inputs. Richard Serra’s Promenade sculpture featured in the 2008 Monumenta exhibition at the Grand Palais in Paris, France is herein hypothesized to have stimulated the body’s vertical and longitudinal axes as it showcased five monumental rectangular solids pitched at a 1.69° angle. Using computerized dynamic posturography we measured the body sway of 23 visitors when fixating a cross, or when observing the artwork (fixating it or actively exploring it with eye movements) before and after walking around and alongside the sculpture (i.e., before and after a promenade). A first fixation at the sculpture increased medio-lateral stability (in terms of spectral power of body sway). Eye movement exploration in the depth of the sculpture increased antero-posterior stability [in terms of spectral power and canceling time (CT) of body sway] at the expense of medio-lateral stability (in terms of CT). Moreover, a medio-lateral instability associated with eye movement exploration before the promenade (in terms of body sway sensu stricto) was canceled after the promenade. Finally, the overall medio-lateral stability (in terms of spectral power) increased after the promenade. Fourteen additional visitors were asked to stand in a dark room and adjust a luminous line to what they considered to be the earth-vertical axis. The promenade executed within the sculpted environment afforded by Serra’s monumental statuary works resulted in significantly improved performances on the subjective visual vertical test. We attribute these effects to the sculpted environment provided by the exhibition which may have acted as a kind of physiologic “training ground” thereby improving the visitors’ overall sense of visual perspective, equilibrium, and gravity.

  12. Learning the ropes at Richard B. Russell Dam: Net systems for medium head hydropower pumpback and generation fish sampling

    Schilt, C.R. [AscI Corporation, Inc., Calhoun Falls, SC (United States)]|[Univ. of Georgia, Athens, GA (United States); Vu, P.D. [Nylon Net Co., Memphis, TN (United States); Nestler, J.M. [USAE Waterways Experiment Station, Vicksburg, MS (United States)

    At Richard B. Russell Dam on the Savannah River we have been monitoring the magnitude (numbers and masses) and species compositions as well as possible survival of fish entrained in operation of four 85 MW Francis pump turbines. In this paper we review our progress in net design for hydropower application. We also discuss basic net handling and introduce a method for net management in a very turbulent tailrace. This report is meant to share what we have learned at Russell Dam in hopes that it will facilitate similar efforts elsewhere. The commercial fishing industry has evolved methods of net construction and handling that may be applied, with appropriate modification, at dams. The nets we use are most appropriately called trawls in that they have the form of a long sock placed over the penstock or draft tube. These nets are superficially similar to those used in commercial trawling for fish. Important differences are that: (1) the net remains relatively stationary while the water moves through it, not vice versa; (2) water velocities and turbulence are much greater at dams than in commercial fishing operations and (3) mesh sizes are much smaller for environmental sampling than for commercial trawling. And while a fouled trawl may stop the boat that pulls it, the water passed in generation or pumpback (about 140 ft. head at Russell) is for all practical purposes unstoppable. Our nets fish in a very turbulent discharge at 7,000 cu. ft./sec/turbine. Their strength and their ability to pass water effectively under all possible operating conditions are primary concerns. Trawl length, mesh sizes, and hanging ratios are important factors. Although we have had setbacks (usually in the form of torn nets) as this study has developed, we have incrementally improved our net design and handling. We review our net failures and the solutions we have found thus far in both construction and handling.

  13. Evaluation of the Ross fast solution of Richards' equation in unfavourable conditions for standard finite element methods

    Ross [Ross PJ. Modeling soil water and solute transport - fast, simplified numerical solutions. Agron J 2003;95:1352-61] developed a fast, simplified method for solving Richards' equation. This non-iterative 1D approach, using Brooks and Corey [Brooks RH, Corey AT. Hydraulic properties of porous media. Hydrol. papers, Colorado St. Univ., Fort Collins: 1964] hydraulic functions, allows a significant reduction in computing time while maintaining the accuracy of the results. The first aim of this work is to confirm these results in a more extensive set of problems, including those that would lead to serious numerical difficulties for the standard numerical method. The second aim is to validate a generalisation of the Ross method to other mathematical representations of hydraulic functions. The Ross method is compared with the standard finite element model, Hydrus-1D [Simunek J, Sejna M, Van Genuchten MTh. The HYDRUS-1D and HYDRUS-2D codes for estimating unsaturated soil hydraulic and solutes transport parameters. Agron Abstr 357; 1999]. Computing time, accuracy of results and robustness of numerical schemes are monitored in 1D simulations involving different types of homogeneous soils, grids and hydrological conditions. The Ross method associated with modified Van Genuchten hydraulic functions [Vogel T, Cislerova M. On the reliability of unsaturated hydraulic conductivity calculated from the moisture retention curve. Transport Porous Media 1988:3:1-15] proves in every tested scenario to be more robust numerically, and the compromise of computing time/accuracy is seen to be particularly improved on coarse grids. Ross method run from 1.25 to 14 times faster than Hydrus-1D. (authors)

    2018-01-01

    Full Text Available Mining, mineral processing and industrial activities have long been linked to increased levels of radioanuclides in soil in their vicinity. In this work, concentrations of naturally occurring radionuclides in soil samples collected around a rock phosphate storage facility in Richards Bay in South Africa were determined. A total of 90 soil samples were collected and analyzed for 238U and 232Th using neutron activation analysis and 226Ra and 4 K using a HPGe detector. The results revealed the average radioactivity concentrations of 238U, 232Th, 226Ra and 4 K in soil samples collected around the rock phosphate storage area were 28.26 ± 11.40, 29.64 ± 11.50, 32.18 ± 11.50 and 146.77 ± 63.30 Bq. kg−1, respectively, which are higher than the corresponding values of 22.26 ± 8.60, 23.09 ± 9.80, 26.52 ± 11.50 and 117.82 ± 10.04 Bq. kg−1 in soil samples from the control area about 2.0 km–4.5 km away from the rock phosphate storage facility. Furthermore, the all radiological hazard parameters (i.e annual effective dose equivalent, annual gonadal dose equivalent, the absorbed dose rate in air, the radium equivalent activity and the external Hazard Index investigated in this study were below the maximum recommended safety limit. The observed 238U, 232Th, 226Ra and 4 K levels indicate contributions from anthropogenic activities with no significant health risks to humans or to the environment. Hence, in terms of terrestrial gamma radiation from soil, rock phosphate storage within this area does not pose any significant radiation hazard to the workers and dwellers.

    Vicente Enrique Montes Nogales

    2013-04-01

    Full Text Available For his last novel, Cameroonian writer Richard M. Keuko, drew inspiration from African traditions and, chiefly, from epic narratives originating in Central Africa that continue to spark great interest in local communities. The protagonist of the story fleshes out the specific traits of the epic hero, which is why the narrator, following suit the ancient bards’ tradition, emphasizes his courage, strength, pride and moral superiority. Further features such as the dialogic structure of the text –which enables the narrator to address the reader directly– and the inclusion of a number of oral texts, rally this work with the epic genre.

    Herzberg, D L

    2001-01-01

    This paper examines the social thought of University of Wisconsin professors Richard T. Ely, John R. Commons, and Edward A. Ross during World War I. Like many of their fellow scholars, these three were actively involved in the pro-war effort. Although their support for the war was strongly conditioned by personal and occupational considerations, the impact of their wartime service was not restricted to those realms. Their social thought, which they impressed into service explaining and justifying the war, was itself altered in subtle and sometimes surprising ways by the forceful positions they took on the political, economic, and racial significance of the conflict.

    1976-01-01

    This 1976 photo shows the X-24B on the Rogers Dry Lake, adjacent to the NASA Dryden Flight Research Center, Edwards, California, with research pilots Einar Enevoldson, John Manke, Richard Scobee, Tom McMurtry, Bill Dana, and Michael Love in front of it. Scobee went on to become an astronaut in NASA's Space Shuttle program and perished in the explosion of the Space Shuttle orbiter 'Challenger' in 1986. The X-24 was one of a group of lifting bodies flown by the NASA Flight Research Center (now Dryden Flight Research Center), Edwards, California, in a joint program with the U.S. Air Force at Edwards Air Force Base from 1963 to 1975. The lifting bodies were used to demonstrate the ability of pilots to maneuver and safely land wingless vehicles designed to fly back to Earth from space and be landed like an airplane at a predetermined site. Lifting bodies' aerodynamic lift, essential to flight in the atmosphere, was obtained from their shape. The addition of fins and control surfaces allowed the pilots to stabilize and control the vehicles and regulate their flight paths. Built by Martin Aircraft Company, Maryland, for the U.S. Air Force, the X-24A was a bulbous vehicle shaped like a teardrop with three vertical fins at the rear for directional control. It weighed 6,270 pounds, was 24.5 feet long and 11.5 feet wide (measuring just the fuselage, not the distance between the tips of the outboard fins). Its first unpowered glide flight was on April 17, 1969, with Air Force Maj. Jerauld Gentry at the controls. Gentry also piloted its first powered flight on March 19, 1970. The X-24A was flown 28 times in the program that, like the HL-10, validated the concept that a Space Shuttle vehicle could be landed unpowered. The fastest speed achieved by the X-24A was 1,036 miles per hour (mph-Mach 1.6). Its maximum altitude was 71,400 feet. It was powered by an XLR-11 rocket engine with a maximum theoretical vacuum thrust of 8,480 pounds. The X-24A was later modified into the X-24B

    Directory of Open Access Journals (Sweden)

    Sérgio Eduardo Ferraz

    2014-03-01

    Full Text Available Este artigo examina o pensamento filosófico de Richard Rorty e, em particular, sua dimensão política, delineando seu tratamento original e crítico de temas centrais à teoria política contemporânea. O objetivo do texto é triplo: chamar a atenção para a fertilidade das ideias de um autor ainda pouco lido no Brasil (i, assinalar as notáveis consequências corrosivas da abordagem rortyana para pressupostos e pretensões fundantes de importantes vertentes da teoria política (ii, e, numa ótica mais positiva, apontar o potencial inspirador dos escritos desse autor para a reflexão sobre novos modos de justificação da democracia (iii. Salientam-se também, nesse último caso, os limites impostos a esse tipo de empreitada político-intelectual. A abordagem empregada consiste em demarcar os contornos gerais do projeto filosófico do autor, seguindo-se uma apresentação dos tópicos mais propriamente políticos da obra de Rorty. Mais especificamente, o artigo explora a proposta rortyana de substituição da noção de verdade pela de justificação, assinalando-se suas consequências para pretensões de verdade, objetividade e universalismo, presentes em diversas linhas da teoria política. Nesse veio, o artigo discute as eventuais implicações relativistas das teses rortyanas, chegando-se, por essa rota, às ideias de contingência, imaginação e persuasão, núcleos conceituais vitais à reflexão em tela. Um breve contraste com posições de autores como Habermas e Rawls, caros ao próprio Rorty, é esboçado no propósito de tornar mais clara a especificidade da abordagem rortyana da política. Transitando, do modo assinalado, por esses tópicos, o texto resulta em um panorama sintético da perspectiva rortyana acerca do que vem a ser, contemporaneamente, uma "política democrática", liberta de "universalismos" e "objetividades", na qual ganham estatuto decisivo questões de justificação, tolerância e coexist

    Mildenberger, F

    2001-01-01

    At the beginning of 20th century, genetic research was carried out by many different branches of science. Biology, zoology, medicine, psychiatry, and psychology took part, so some results were a mixture of the involved sciences and not pure genetic. One researcher, who used his experiences from zoology to explain sexual orientation in the human race, was Richard B. Goldschmidt (1878-1958). He published several articles between 1916 and 1927 on this topic before he reconsidered his own theses. Greatest feedback he became during the Third Reich. Although being Jewish he became professor for life in autumn 1933. When he left Berlin for Berkeley in 1936, he began a new scientific career, leaving all old theories and ideologies behind. But his "Umwandlungsmännchen"-theory was restarted by some German psychiatrists to explain homosexuality. One of these men was Theo Lang (1898-1957), who was allowed to publish his articles in the USA and in Switzerland. Lang had been one of the founders of the association of Nazi doctors and was a member of the SA. Moreover, after 1945 during Denazification he was allowed to call for Richard Goldschmidt as witness for his own defence.

    Full Text Available The real cause of Soeharto’s fall from the Indonesian presidency remains a mystery. Richard Mann (1998 launched three significant rhetorical questions: (a Was President Soeharto toppled by student demonstrators and people’s power? (b Was he brought down by the withdrawal of support from the United States? (c Or, was his sudden fall brought about by all of the two plus large doses of Oriental plotting and scheming? This article attempts to analyze Richard Mann’s PSBDS in terms of its macrostructure in order to find out the real cause of Soeharto’s fall. The analysis is substantiated by different resources as linguistic evidences, to justify the validity of the findings. The study revealed a proposition that critical reading is the key to successful comprehension of a text which may include a crosschecking with other resources, a careful identification of the generic structure of a text, and paying attention to how an author positions his or her readers. The article concludes, that in fact, Soeharto resigned from presidency on his own wisdom in order to avoid more bloodshed in Indonesian dreamland.

  14. Exact and grid-free solutions to the Lighthill-Whitham-Richards traffic flow model with bounded acceleration for a class of fundamental diagrams

    KAUST Repository

    Qiu, Shanwen

    2013-09-01

    In this article, we propose a new exact and grid-free numerical scheme for computing solutions associated with an hybrid traffic flow model based on the Lighthill-Whitham-Richards (LWR) partial differential equation, for a class of fundamental diagrams. In this hybrid flow model, the vehicles satisfy the LWR equation whenever possible, and have a constant acceleration otherwise. We first propose a mathematical definition of the solution as a minimization problem. We use this formulation to build a grid-free solution method for this model based on the minimization of component function. We then derive these component functions analytically for triangular fundamental diagrams, which are commonly used to model traffic flow. We also show that the proposed computational method can handle fixed or moving bottlenecks. A toolbox implementation of the resulting algorithm is briefly discussed, and posted at https://dl.dropbox.com/u/1318701/Toolbox.zip. © 2013 Elsevier Ltd.

    2018-02-01

    In their Nobel Lectures of 1956, the two cardiopulmonary physiologists André Cournand and Dickinson Richards described the future projects that they considered important for rounding up their impressive scientific achievements. One of them called for work that brought together structure and function of the lung in a systematic way. They challenged a young anatomist to undertake this in their cardiopulmonary laboratory at Bellevue Hospital. The first steps established the need for quantitative information on the structures that form the pulmonary gas exchanger as well as the airway tree. This resulted in a new approach to lung anatomy: morphometry would provide the quantitative information for modeling structure-function relations in the lung, and eventually in the entire respiratory system, thus allowing a rational analysis of how structures affect or limit functions.

    KAUST Repository

    Qiu, Shanwen

    2012-07-01

    In this article, we propose a new grid-free and exact solution method for computing solutions associated with an hybrid traffic flow model based on the Lighthill- Whitham-Richards (LWR) partial differential equation. In this hybrid flow model, the vehicles satisfy the LWR equation whenever possible, and have a fixed acceleration otherwise. We first present a grid-free solution method for the LWR equation based on the minimization of component functions. We then show that this solution method can be extended to compute the solutions to the hybrid model by proper modification of the component functions, for any concave fundamental diagram. We derive these functions analytically for the specific case of a triangular fundamental diagram. We also show that the proposed computational method can handle fixed or moving bottlenecks.

  17. Imitating Jesus, yes – but which Jesus? A critical engagement with the ethics of Richard Burridge in Imitating Jesus: An inclusive approach to New Testament ethics (2007

    Directory of Open Access Journals (Sweden)

    Jonathan A. Draper

    2009-08-01

    Full Text Available This paper examines the attempt by Richard Burridge in his recent book, Imitating Jesus: An inclusive approach to New Testament ethics (2007, to build an engaged Christian ethics starting with the historical Jesus but taking full account of the insights into the perspectives of the four gospels in their own right, based on their genre as Greek bioi. While Burridge’s approach is applauded and regarded as a major step forward, it is critiqued here on his selectivity in his presentation of the results of two decades of research into the Jesus of history. Burridge’s selection of the South African experience in the struggle against apartheid as his ‘test case’ is also questioned, since the issues in such struggles for justice appear more straightforward to outsiders than they do to insiders and his analysis raises more questions than it answers.

  18. Will the real Robert Neville please, come out? Vampirism, the ethics of queer monstrosity, and capitalism in Richard Matheson's I am legend?

    Science.gov (United States)

    Khader, Jamil

    2013-01-01

    In this article, I argue that Richard Matheson's (1954) vampire novella, I Am Legend, encodes the protagonist's, Robert Neville, traumatic recognition of his queer sexuality in its monstrosity (the unspeakability of male penetrability). Neville's identification with and desire for his undead neighbor, Ben Cortman, are symbolically codified through three different registers: intertextual references to vampiric conventions and codes, the semiotics of queer subculture, and a structure of doubling that links Neville to the queer vampire. Although Neville avoids encountering his unspeakable queer desire, which could be represented only at the level of the Lacanian Real, he must still confront Cortman's obsessive exhortations for him to come out. Only when he symbolically codifies his abnormality in its own monstrosity, by viewing himself through mutant vampires' eyes, can Neville reconfigure the ethical relationship between self and other, humans and mutant humans-vampires. However progressive Matheson's novella is in its advocacy of minority sexual rights, it still renders capitalism's problematic relationship with queer subjectivity invisible. Although capitalism overdetermines every aspect of the social field and makes Neville's daily life possible in its surplus enjoyment, the fundamental antagonism (class struggle) in capitalism is obscured by the assertion of identity politics.

    2009-01-01

    The conference was related with some of the major questions concerning global energy governance today, the role of the different international organizations dealing with energy, the rules of the game between market and state players, the efforts to deal with climate change, and the integration of emerging countries in global energy governance, the roles of the different international organizations dealing with energy (will we see further fragmentation or more cooperation between them?). Tatsuo Masuda in his contribution discussed global energy governance from an oil perspective. Andre Mernier noted the particular nature of the Energy Charter, which, as it is founded upon an international treaty, is unlike other organizations in being legally binding. The legal basis of the organization means that agreements are especially powerful. Then Richard H. Jones underlined that last summer's volatility in oil markets, the ensuing financial and economic crisis, the major disruption in gas supplies to European markets this winter and the upcoming climate change negotiations have led to increasing calls for a stronger global dialogue on energy issues. This dialogue should deal with prices and investment, energy security and climate change

    Full Text Available Il contributo proposto ha l’obiettivo di analizzare alcuni significativi brani del tessuto urbano della periferia est di Roma, adottando metodi interpretativi legati alla storia, alla società, alla programmazione urbanistica e alla costruzione. Gli aspetti salienti del quadrante orientale della periferia romana verranno così delineati partendo “dal di dentro”, sottolineandone i percorsi, gli spazi e i nuclei compositivi che sono all’origine della struttura e della forma stessa dei quartieri disposti a cavallo del Grande Raccordo Anulare. In questo ambito, si pone l’attenzione su alcuni episodi chiave che vedono protagoniste le nuove chiese che riescono a creare una centralità all’interno dei quartieri periferici sostituendo le biblioteche, le piazze e i centri commerciali.  Analizzando da vicino questi esempi, si scopre come di recente sono state realizzate chiese firmate da architetti di fama internazionale proprio allo scopo di rafforzare, o meglio di costruire, un fattore identitario per ciascun quartiere ubicato nel settore orientale della città. Partendo quindi dal generale si arriva a indagare una chiesa e un quartiere che possono essere considerati un modello da seguire per tutta la periferia a ridosso del GRA: la chiesa giubilare di Dio Padre Misericordioso progettata da Richard Meier nel quartiere di Tor Tre Teste. La sequenzialità degli eventi che hanno contraddistinto il concorso per la progettazione della chiesa, la scelta della proposta di Richard Meier, la complessità del cantiere, l’analisi tecnica, stilistica e simbolica della realizzazione finale sono quindi analizzate nell’ambito del rapporto con il quartiere e del tentativo di realizzare (attraverso di essa un centro di attrazione per tutta la periferia.   The article analyses some significant parts of the urban tissue at the eastern periphery of Rome, using the interpretative methods inherent to history, society, urban programming and construction

    Full Text Available Abstract – This paper will analyze the ‘historical’ novel Gould’s Book of Fish (2001 by the Tasmanian writer Richard Flanagan with the aim of reflecting upon the power of the creative word as a means to forge reality, shape identities, mask or unmask truths, and also to prefigure a different, alternative world order based on commonly negotiated and thus shared values. The postmodernist revisiting of the traditional genre of the historical novel does not compromise the postcolonial commitment of the writer: Flanagan’s incursions into the Australian colonial past are informed by his concern for urgent social and political causes which has characterized his unswerving fight against all systems of inequality and exploitation. In his novel, the subversion of the linear causal relation of events which calls into question the truthfulness and objectivity of history, together with the foregrounded metanarrative reflection on the art of writing, contribute to the revisiting and re-discussing of the myth of progress and the cult of rationality at the very roots of Western civilization and of its imperialistic enterprise. Flanagan’s ‘anti-historical’ historical novel tackles urgent questions about modernity interrogating the founding narratives of the Australian national identity, in order to explore the uncontrollable and shifting areas of the contemporary ‘transnation’ in which the traditional categories shaping subjectivities are disrupted. As the paper will demonstrate, the writer digs into the past of his nation not simply in order to unravel its hidden histories but to detect the profound, inextricable interconnections with the present across different times and spaces. Feelings and experiences that exist above and beyond historical contingencies and cultural differences represent the writer’s privileged area of investigation as they trespass upon conventional and artificial boundaries revealing what it is that makes us all

    Full Text Available Richard Wright's collection of short novella's, Uncle Tom's Children, was originally published in 1938; in 1940, after the success of Native Son, a new printing of the text appeared with two additions. The first was the introductory essay entitled "The Ethics of Living Jim Crow," which was written in 1937, and later served as part of Black Boy. The second was the novella "Bright and Morning Star." Michel Fabre notes that Harper's Magazine rejected this story, "but since it fit Party specifications even better than had the four previous stories, New Masses published it as part of a special literary supplement on May 10, [1938]" (164 . In fact, perhaps because New Masses originally published the final story, critical attention to the revised edition of book almost exclusively posits that the 1940 edition reflects Wright's commitment to Communism at the time. However, several of Wright's other writings-including the introductory essay to the 1940 edition, "The Ethics of Living Jim Crow;" "Blue print for Negro Writing," first published in New Challenge in the fall of 1937; "I Tried to be a Communist," first published in Atlantic Monthly in August and September 1944; and his responses to the Communist party's review of Native Son in 1940-also indicate that his focus in the late 1930s was more on the development of an individual black consciousness than on advancing the causes of the Communist party. By juxtaposing the final two stories, "Fire and Cloud" and "Bright and Morning Star," and considering them in terms of the other writings indicated above, I argue that the 1940 edition of Uncle Tom's Children (with the two additions demonstrates Wright's growing ambivalence with the Communist Party between the years of 1937 and 1940.

  3. Beyond the Soundtrack: Representing Music in Cinema, a cura di Daniel Goldmark, Lawrence Kramer e Richard Leppert, Berkeley, University of California Press, 2007

    Full Text Available Beyond the Soundtrack: Representing Music in Cinema (edited by Daniel Goldmark, Lawrence Kramer and Richard Leppert, Berkeley, University of California Press, 2007, viii-324 pp. offers sixteen essays of various authors about film music. These papers were presented in 2004 in a study congress at the University of Minnesota. In introducing the book, the editors assert an assumption, today broadly accepted: indeed they affirm, that music has traditionally been regarded as a subordinate element in cinematographic text: film music literature still has a marginal position in the much larger field of film studies which focuses on image, narrative, film history. In this theoretical and historiographic context, the expression “Beyond the Soundtrack” is meant to be more than a title: it is the manifesto of a conceptual shift. We can summarize this change in reconsidering the importance of film music, in order to understand a movie not only as a visual, but also as a musical medium. The change of paradigm brings renewed questions and completely new issues. If we abandon the assumption, at this point obsolete, that film music has a mere functional role, it will be necessary to ask not how to conceptualize the use of music in film, but rather how the film conceptualizes music: how films imagine music, how films represent music as an artistic and social phenomenon, and how films position music as an integral parts of a fictional world. Such questions aim to consider film music not as an atmospheric expedient, but «as an agent, a force, and an object engaged in ongoing negotiations with image, narrative, and context», as the editors assert at the very beginning of their book.

  12. The "dirty weather" diaries of Reverend Richard Davis: insights about early colonial-era meteorology and climate variability for northern New Zealand, 1839-1851

    2016-03-01

    Reverend Richard Davis (1790-1863) was a colonial-era missionary stationed in the Far North of New Zealand who was a key figure in the early efforts of the Church Mission Society. He kept meticulous meteorological records for the early settlements of Waimate North and Kaikohe, and his observations are preserved in a two-volume set in the Sir George Grey Special Collections in the Auckland Central Library. The Davis diary volumes are significant because they constitute some of the earliest land-based meteorological measurements that were continually chronicled for New Zealand. The diary measurements cover nine years within the 1839-1851 time span that are broken into two parts: 1839-1844 and 1848-1851. Davis' meteorological recordings include daily 9 a.m. and noon temperatures and midday pressure measurements. Qualitative comments in the diary note prevailing wind flow, wind strength, cloud cover, climate variability impacts, bio-indicators suggestive of drought, and notes on extreme weather events. "Dirty weather" comments scattered throughout the diary describe disturbed conditions with strong winds and driving rainfall. The Davis diary entries coincide with the end of the Little Ice Age (LIA) and they indicate southerly and westerly circulation influences and cooler winter temperatures were more frequent than today. A comparison of climate field reconstructions derived from the Davis diary data and tree-ring-based winter temperature reconstructions are supported by tropical coral palaeotemperature evidence. Davis' pressure measurements were corroborated using ship log data from vessels associated with iconic Antarctic exploration voyages that were anchored in the Bay of Islands, and suggest the pressure series he recorded are robust and can be used as "station data". The Reverend Davis meteorological data are expected to make a significant contribution to the Atmospheric Circulation Reconstructions across the Earth (ACRE) project, which feeds the major data

  13. Modeling Large Water Infiltration Events in Small Plots Using the 1-D Finite Water-content Method and Numerical Solutions to the Richards' Equation.

    The ability of soil to infiltrate large volumes of water is fundamental to managed aquifer recharge (MAR) when using infiltration basins or agricultural fields. In order to investigate the feasibility of using agricultural fields for MAR we conducted a field experiment designed to not only assess the resilience of alfalfa (Medicago sativa) to large (300 mm), short duration (1.5 hour), repeated irrigation events during the winter but also how crop resilience was influenced by soil water movement. We hypothesized that large irrigation amounts designed for groundwater recharge could cause prolonged saturated conditions in the root-zone and yield loss. Tensiometers were installed at two depths (60 and 150 cm) in a loam soil to monitor the changes in soil matric potential within and below the root-zone following irrigation events in each of five experimental plots (8 x 16 m2). To simulate the individual infiltration events we employed the HYDRUS-1D computational module (Simunek et al., 2005) and compared the finite-water content vadose zone flow method (Ogden et al. 2015) with numerical solutions to the Richards' equation. For both models we assumed a homogenous and isotropic root zone that is initially unsaturated with no water flow. Here we assess the ability of these two models to account for the control volume applied to the plots and to capture sharp changes in matric potential that were observed in the early time after an irrigation pulse. The goodness-of-fit of the models was evaluated using the root mean square error (RMSE) for observed and predicted values of cumulative infiltration over time, wetting front depth over time and water content at observation nodes. For the finite-water content method, the RMSE values and output for observation nodes were similar to that from the HYDRUS-1D solution. This indicates that the finite-water content method may be useful for predicting the fate of large volumes of water applied for MAR. Moreover, both models suggest a

    Full Text Available It is usually said that the memory of the war period had been completely reversed in the former Soviet borderlands since the collapse of the USSR, turning former “traitors” into heroes or victims. However, attempts to set up a new approach of the Nazi occupation and collaboration are rooted in the “Thaw” period. I remember everything, Richard – dealing with the Latvian legion, started to be considered in 1957. That coincided both with the massive return of the Latvian deportees from Siberia, and with a renewal of trials against war criminals. Produced only in 1966, the film reflected the social tensions going along with the sensitive topic, and presented a point of view far more nuanced than the official figure of the “Latvian traitor” imposed during the Stalinist period. Based on interviews, archival material and film analysis, this article aims at understanding through the film-making process the connection between the deep changes of the political meaning of the war period, and the social composition of film production.

    Sexuality has been defined a central feature of personal identity since the epoch of enlightenment and has gradually become a decisive issue also in societal and political terms. A major transfer from religion and religious institutions to medicine and medical experts and later on to neuropsychiatrists has to be underlined in the primary position to assess "normal" and "deviant" manifestations of sexuality. Richard Freiherr von Krafft-Ebing and Sigmund Freund play an eminent role in this "discourse on sexuality" (M. Foucault) during the nineteenth and beginning twentieth century on the way to modern sexology. Within this overarching context Krafft-Ebing's and Freud's theoretical conceptualizations of sexuality and perversion will be sketched and basic clinical and societal implications there out will be discussed.

    The study of Einstein's theory of general relativity experienced a renaissance beginning in the early 1960s. Prior to this resurgence of interest, general relativity was isolated from mainstream physics-admired for its elegance, perhaps, but only from a distance. The generation of students who risked their careers by entering this neglected field has now reached the age of festschrifts. In June of 2000, Caltech hosted ;Kipfest,; a conference in honor of Kip Thorne's 60th birthday. Thorne started graduate school at Princeton in 1962 and began research in general relativity under John Wheeler's guidance in the heady early days of the renaissance. Since then, he has played a prominent role in general relativity: as co-author of the influential textbook Gravitation, as a leader in research regarding astrophysical applications of Einstein's theory, and as a co-founder and chief advocate for the Laser Interferometer Gravitational Wave Observatory (LIGO), to mention a few aspects of his far-reaching work. ;Kipfest; included 14 speakers discussing fields to which Thorne has contributed. But the conference also reflected Thorne's long-standing commitment to communicating science to a general audience: Igor Novikov, Stephen Hawking, Timothy Ferris, and Alan Lightman gave popular talks at ;Kipfest,; with Thorne himself tricked into delivering a fifth. The Future of Spacetime gathers adaptations of these five lectures, along with a lengthy introductory essay by Richard Price.

    Full Text Available The subject of this paper is one of the central problems of philosophy, which isaptly stated by Hilary Putnam: “How does mind/language hook on to the world?”.This question presupposes a model of knowledge which may be called “the subject--object model of knowledge”. However, contemporary philosophers such as WilfridSellars, Hilary Putnam, Donald Davidson, Richard Rorty, John McDowell, JohnHaugeland and Robert Brandom criticize this traditional model of knowledge. I claimthat at least some versions of neopragmatism look at this problem implicitly assum-ing a transcendental point of view. This istranscendentalism without transcendentalstandpointand can be found in Marek Siemek’s works. This transcendentalismcan be considered in two ways. First, as a therapy – a standpoint that is characteristicof Rorty, who demonstrated that the subject-object model of knowledge is optionaland contingent. Second, as constructivism – this standpoint is represented by Bran-dom, who tries to show that this traditional model is not autonomus.

    2009-01-01

    Dr. Eugene R. Tomer passed away on 2 July 2007 at his home in San Francisco, California. The cause of death was cancer. Tomer was a consulting applied mathematician with a wide range of interests in dynamical astronomy, electromagnetic theory for use in communications, and computational methods of applied mathematics. He was a member of AAS, and the Society for Applied and Industrial Mathematics [SIAM]. With K. H. Prendergast, he co-wrote the influential paper "Self-consistent Models of Elliptical Galaxies," published in the Astronomical Journal 75 (1970), 674-679. This paper has been cited over eighty times. Tomer was born on 13 June 1932. He earned the Ph.D. in Mathematics at the University of California-Berkeley in 1978 (title of dissertation: On the C*-algebra of the Hermite Operator). In 1996 he and A. F. Peterson wrote "Meeting the Challenges Presented by Computational Electromagnetics," a publication of the Naval Postgraduate School at Monterey, California. This writer met Eugene at the 1992 Annual SIAM meeting in Los Angeles in connection with the Activity Group on Orthogonal Polynomials and Special Functions, which the writer chaired at the time. Eugene volunteered to edit the Newsletter of the group, which he did from July 1992 to July 1995. Thanks to his skills and efforts, the Newsletter became a carefully edited, professional publication. Eugene not only organized a Problems Column, attracting questions in pure and applied mathematics, but he also designed the logo for the group. He gave much time and effort to this service, in an era when copy had to be physically assembled and mailed to SIAM Headquarters. Eventually he felt he had done what he could for the Activity Group. He told me that he hoped the Group would get seriously involved with applications such as in astronomy, physics, and sciences that use special function solutions of differential equations. During Tomer's editorship, we communicated mostly by e-mail, our homes being far apart. He was a good friend to the Group and to me, as much as one can be over a separation of thousands of miles. As well, Eugene was an active amateur radio operator, much appreciated by his local amateur radio community, with call sign WI6X. He left behind family, friends, and one son.

  9. Definition and display of steric, hydrophobic, and hydrogen-bonding properties of ligand binding sites in proteins using Lee and Richards accessible surface: validation of a high-resolution graphical tool for drug design.

    1992-05-15

    The accessible surface, described by Lee and Richards (the L&R surface: J. Mol. Biol. 1971, 55, 379), has remarkably useful properties for displaying ligand-protein interactions. The surface is placed one van der Waals radius plus one probe radius away from the protein atoms. The ligands are displayed in skeletal form. With a suitable probe radius, those parts of the ligand in good van der Waals contact with the protein binding site are found superimposed on the L&R surface. Display of the surface using parallel contours therefore provides a very powerful guide for interactive drug design because only ligand atoms lying on or close to the surface are in low-energy contact. The ability of the surface to accurately display steric complementarity between ligands and proteins was optimized using data from small molecule crystal structures. The possibility of displaying the chemical specificity of the binding site was also investigated. The surface can be colored to give precise information about chemical specificity. Electrostatic potential, electrostatic gradient, and distance to hydrogen-bonding groups were tested as methods of displaying chemical specificity. The ability of these methods to describe the complementarity actually observed in the interior of proteins was compared. High-resolution crystal data for ribonuclease and trypsin was used. The environment surrounding extended peptide chains in the protein was treated as a virtual binding site. The peptide chain served as a virtual ligand. This large sample of experimental data was used to measure the correlation between type of ligand atom and the calculated property of the nearest binding site surface. The best correlation was obtained using hydrogen-bonding properties of the binding site. Using this parameter the surface could be divided into three separate zones representing the hydrophobic, hydrogen-bond-acceptor, and hydrogen-bond-donor properties of the binding site. The percentage of hydrophobic ligand

  1. pH tolerance of Daphnia pulex (leydig, emend. , richard)

    Energy Technology Data Exchange (ETDEWEB)

    Davis, P.; Ozburn, G.W.

    1969-01-01

    The survival time and reproduction of female Daphnia pulex in solutions varying in pH have been observed. Dilute sodium hydroxide or sulfuric acid solutions were added to four different diluent waters: distilled water, aerated tap water, aerated and filtered tap water from an aquarium containing Dace minnows, and Mcintyre River water. D. Pulex (initially up to 72 hours old) survived for the duration of the experiment (32 hours) in river water within a pH range of 6.1 to 10.3; in aquarium water within a pH range of 4.3 to 10.4; only at pH 6.4 and pH 7.6 in distilled water; and in none of the solutions using aerated tap water. The dissolved oxygen content was measured at the beginning and end of every experiment and was found never to fall below 6.2 p.p.M. Those individuals which survived were cultured in the laboratory and parthenogenesis was observed at pH values between 7.0 and 8.7.

    Full Text Available A Review of: Trueswell, R. L. (1969. Some behavioral patterns of library users: The 80/20 rule. Wilson Library Bulletin, 43(5, 458-461. Objective – To demonstrate the relationship between library circulation and the percent of a library's holdings satisfying circulation. Design – Retrospective cohort study of library circulation data. Setting – Cambridge and Northampton, Massachusetts, United States of America. Subjects – The users of the monographic holdings of the Air Force Cambridge Research Laboratory Library and the Forbes Public Library. Methods – Trueswell compiled circulation data from the Air Force Cambridge Research Laboratory Library over a period of 5 years, ostensibly from 1964-1969. Additionally, he gathered circulation data from Forbes Public Library. Trueswell compared each respective collection of data against the entire holdings of each library, after which he converted each measure to a percentage of the whole. Main Result – Based on the collected data, Trueswell found that the percentages of both libraries’ holdings that satisfy circulation follow a power law distribution. He compared this with a previous study measuring journal circulation at a Health Sciences Library that exhibited the same pattern. He stated that these similar distributions demonstrated the "80/20 Rule." The distribution is such that any given percent of circulation will provide the percent of a library’s circulating holdings necessary to satisfy it. Additionally, Trueswell found that 75 percent of current circulation had circulated at least once within the preceding year. Conclusion – The findings have implications for core collection development, purchasing multiple copies of a given title, determining the optimal size of a library's collection, and weeding. Trueswell also submits the idea of developing regional interlibrary loan centers for books that do not circulate often, as a cost saving measure for most libraries.

    2006-03-01

    Now it is even strange to think that in the early 50-ies the second order transitions and the liquid -- vapor critical point were considered as different fields of physics. In the USSR this lack of understanding (as everything in the USSR) had also a political dimension. Being a graduate of Kharkov University (domain of L.Landau) I was inclined to work in a framework of Landau-theory of the critical point. Having carefully analysed the published experimental data I discovered that the scattering of the data in the vicinities of both critical points and phase transitions was much higher than the implemented equipment had allowed [1]. For me it was a true sign of wrong conditions of measurements. As a result I had adjusted my experiment to the specific condition of the critical point. We worked together with the group of students of Kharkov University who had shared my enthusiasm. When we were already on a halfway of our own measurements I was deeply impressed by the excellent result of M.J.Buckingham and W.M. Fairbank on the λ-point of Helium [2]. Their achievement had turned our own measurements into a sort of experimen-tum crucis: should one expect a singularity also in the critical point or shouldn't? Experimental data on isochoric heat capacity near the critical point looked really similar (but not identical) to the singularity near the λ-transition. Both found their common ground in lattice models of different kinds [3]. The scaling concept was suggested to explain the universal features of both phenomena originated from developing fluctuations [4]. Our work was noticed first by C.Domb and M.Fisher in England. Michael was especially persistent in his demands that the Sovjet authorities would allow us a free communication. He produced a sort of frustration in their bureaurocratic heads. But it was great to feel not to be condemned for an eternal isolation in the USSR. All this development (now international) has opened way to express the properties of all liquids (including mixtures) in the vicinities of the singular points by the universal functions of reduced coordinates [5]. But the very existence of the critical point (and the liquid state itself) is in fact not an universal property of matter [6]. The freezing is depen-dent on a symmetry of packing and on a form of a potential well. It means the lower limit of the liquid state cannot be universal. However, if the freezing is somehow avoided the metastable critical point may be achieved instead [7]. And the universal features of the critical phenomena may be observed there again.

    Despite of usefulness of some elements and implications of Rorty’s metaphilosophy (such as his emphasis on freedom, democracy, and pluralism as well as his insisting on philosophical humility and avoiding scientific pride, it is faced with several problems, including 1 ignoring the referential and realist features of language, 2 confusing interpretation and reality, 3 eliminating the border between objectivity and subjectivity, 4 interfering of public and private life, and 5 ignoring the need of science, culture, technology and, in particular, politics, in philosophy. The authors try to show and analyze some elements of these problems.

Mas essa aposta resvala claramente num pragmatismo moral mal disfarçado. Luhmann, ao contrário, levou até o fim a preocupação, abandonada por Rorty, de elaborar uma teoria antimetafísica e despida de um projeto normativo para a sociedade contemporânea. Sua teoria dos sistemas enfrenta as contingências do mundo, excluindo tudo que for externo ao sistema, ou seja, tudo que não possa se tornar um mecanismo de manutenção da identidade dos sistemas face à complexidade do mundo.

  17. Dalhaus – Kunze: a dialogue on Richard Wagner’s musical drama

    Directory of Open Access Journals (Sweden)

    Krzysztof Kozłowski

    2010-01-01

    Full Text Available This article supports the thesis that Carl Dalhaus’s interpretation of the Wagnerian musical drama (drama is here understood as a “dramatic musical form” existing in the score, which fully comes into being only on stage as a concrete artistic creation is not totally in opposition to StefanKunze’s interpretation, according to whom the Wagnerian drama, as the whole musical theatre of Wagner, is in fact the “imaginative theatre”. It is possible to defend this thesis thanks to my conviction that “imaginativeness” of the theatre and its reality (staging are not mutually exclusive although they create a particular tension. This article consists of two parts. The first one presents Carl Dalhaus’s interpretation according to which the staging belongs to the history of a particular work of drama, forming its unique character every time again. The other part of the text discusses Stefan Kunze’s interpretation that the imaginary theatre is a part of the dramatic-musical form. There is a punch line, or a specific coda, at the end of the second part of the article, which explains the meaning of both, Dalhaus’s and Kunze’s points of view, seen also from the perspective of Wagner’s musical drama itself. My interpretation presented in this article is – referring to the current state of research and in spite of a large number of literature on this subject – new and original although the meaning of both theories is of great importance for the Wagnerian studies. My interpretation may serve to better understand both – the paradox of Wagnerian studies and the artistic work to which these theories refer.

    Full Text Available Pese a que los trabajos de Schmidt-Nowara y de Langhorne hacen referencia a muchos aspectos de carácter específico y concreto, también dan pie a una serie de comentarios de índole mucho más general, al igual que ocurre con el tema global de este simposio. Este breve comentario se centrará en alguno de esos temas más amplios que suscita la lectura de las dos ponencias en cuestión, si bien se ocupará igualmente de algunos de los aspectos más concretos que en ellas se plantean. Aunque con matices divergentes, ambas ponencias podrían calificarse de postcoloniales. El trabajo de Schmidt-Nowara asume tal perspectiva de manera abierta y la formula teóricamente, mientras que el de Langhorne lo hace de forma menos explícita. Contemplados desde la perspectiva del actual cambio de siglo, resulta evidente que las grandes potencias de hace cien años, con su extensión territorial relativamente pequeña y sus grandes imperios coloniales, fracasaron en su intento de perpetuar su pujanza geopolítica. No cabe duda de que, durante buena parte de la segunda mitad de nuestro siglo, las grandes potencias mundiales han sido dos estados dotados de una gran extensión territorial continua. Aparentemente, las posesiones ultramarinas, por más que hayan podido resultar de utilidad a corto plazo, han reportado pocos beneficios a la larga.

    Full Text Available Je breiter der Infrastruktur-Anschluss eines Landes an das World Wide Web, desto größer die Angriffsfläche im Fall eines Netzkriegs. Die Messung der virtuellen Kampfkraft erfolgt auf Basis von drei Faktoren: Offensivkraft, Defensivfähigkeit und die Abhängigkeit vom Internet. Die USA verfügen als "Supermacht" zwar über die größte virtuelle Offensivkraft, gleichzeitig steht die Nation Cyberangriffen sehr verwundbar gegenüber. Dagegen sind in Nordkorea kaum Systeme vom Internet abhängig. Obwohl die offensiven Netzkriegskapazitäten Nordkoreas verhältnismäßig gering sind, präsentiert sich die virtuelle Kampfkraft des nordkoreanischen Regimes in Bestform. Die Verwundbarkeit ziviler Systeme, insbesondere der Energieversorgung, muss in direkter Korrelation mit deren Anknüpfung an das Internet betrachtet werden. The more broadly connected a country’s infrastructure and energy distribution, the greater its vulnerability in the event of a cyber war. Measuring this virtual fighting power is based on three factors: offensive and defensive strength, as well as dependency on the Internet. As a superpower, the USA has the greatest virtual offensive strength available. At the same time, the nation is most susceptible to cyber attacks and therefore most vulnerable. By contrast, North Korea’s offensive cyber fighting power is relatively small, but its overall cyber war capabilities are cutting-edge. The vulnerability of civil systems, especially power supply, must be viewed in direct correlation to their connection to the Internet.

  3. CORR®ORS Richard A. Brand Award: Clinical Trials of a New Treatment Method for Adhesive Capsulitis.

    Science.gov (United States)

    Badalamente, Marie A; Wang, Edward D

    2016-11-01

    Conservative and even surgical management of adhesive capsulitis often is prolonged and painful. Management of adhesive capsulitis is lacking evidence-based controlled clinical trials. We asked: (1) Does a collagenase clostridium histolyticum (CCH) injection lyse shoulder capsule collagen in adhesive capsulitis and at what dose? (2) Can a shoulder capsule injection be administered extraarticularly? (3) Do CCH injections result in better scores for pain and function than can be achieved with physical therapy among patients with adhesive capsulitis? First, 60 patients with adhesive capsulitis were evaluated by clinical examination. To make the diagnosis of adhesive capsulitis, a patient had to have restricted active ROM of at least 60° in total active ROM in the affected shoulder compared with the unaffected contralateral shoulder; with the scapula stabilized, external rotation with the elbow at the side was a very important determinant. Patients were randomized to receive a single injection of 0.5 mL placebo or 0.145, 0.29, or 0.58 mg CCH. All 60 patients were followed up at 30 days. After that, if patients did not attain treatment thresholds they were eligible for up to five open-label 0.58-mg collagenase injections. For the longer-term followup in the open-label phase, 53 patients (83%) were followed to 12 months, 46 (77%) for 24 months, 36 (60%) for 36 months, 37 (62%) for 48 months, and 25 (42%) for 60 months. The extraarticular injection was directed at the anterior shoulder capsule with the patient in the supine position. To prove that these injections could be delivered reliably to the anterior shoulder capsule extraarticularly, the next study involved volunteers without adhesive capsulitis, in which 10 volunteers received a 10-mL injection of normal saline under ultrasound guidance. Finally, to determine the efficacy and dosing of CCH, four cohorts of 10 patients received up to three ultrasound-guided injections separated by 21 days. These injections were administered at one of four dose-volume levels. A fifth cohort of 10 patients was used as a control group and performed standardized home shoulder exercises only. All patients performed standardized home shoulder exercises three times daily. For Study 3, followup was at 22, 43, 64, and 92 days. No patients were lost to followup. In the first study, a single CCH injection did not provide clinically important improvements from baseline in active ROM, passive ROM, and function and pain scores compared with patients who received placebo. Ultrasound guidance confirmed extraarticular injection of the shoulder capsule in Study 2. The CCH injection was more effective than exercise therapy alone at 0.58 mg/1 mL and 0.58 mg/2 mL compared with exercise only in the primary measure of efficacy (active forward flexion) as shown in Study 3. For active forward flexion the mean in degrees in the 0.58 mg/2 mL group was 38° compared with 12° in the exercise-only group (p = 0.03). For active forward flexion the mean in the 0.58 mg/1mL group was 43° compared with 12° in the exercise-only group (p = 0.01). Extraarticular injections of CCH for treatment of adhesive capsulitis were well tolerated and seem effective compared with exercise therapy. Future FDA-regulated clinical trials must verify CCH injection therapy for adhesive capsulitis. Level II, therapeutic study.

  18. An analysis of Richard Prince's "Lake Resort Nurse": using an image to expose and critically reflect on stereotypes in nursing.

    Science.gov (United States)

    Holmes, Vicki C

    2012-01-01

    Our interactions with images, created and viewed within contexts, are a significant means through which we construct and interpret our values and beliefs. Nurses' efforts at monitoring images to encourage accurate portrayals of nurses' work have had little influence on the way nurses are represented or the inherent ability of images to shape perceptions of nurses' work. One explanation for this lack of influence is that viewers do not closely attend to the ways in which we make meaning of everyday images. This inattention creates passive viewers, vulnerable to and more likely to internalize messages (G. Dines & J. Humez, 2011). Misunderstandings about nursing leave nurses vulnerable to contexts and influence the outcomes of at least 2 issues, the nursing shortage and the provision of quality care. Prince, in his painting "Lake Resort Nurse," utilizes the artistic strategies of expressionism, appropriation, and reflexivity to expose stereotypes and provides an opportunity for reflection on the potential impact these stereotypes have on the profession. He provides a means through which we can recognize that images are significant contributors to how understandings of nursing and nurses are shaped. New understandings of nursing, gained through reflection and dialog, subsequently influences perceptions of the value of nurses' work and their contribution to health care.

  2. The Richard C. Schneider Lecture. New dimensions of neurosurgery in the realm of high technology: possibilities, practicalities, realities.

    Fueled by a buoyant economy, popular attitudes and demands, and parallel progress in transferable technical and biological areas, neurosurgery has enjoyed a remarkable quarter of a century of progress. Developmental trends in the discipline have included the following: 1) a refinement of preoperative definition of the structural substrate, 2) miniaturization of operative corridors, 3) reduction of operative trauma, 4) increased effectiveness at the target site, and 5) incorporation of improved technical adjuvants and physical operative tools into treatment protocols. In particular, the computer has become a formidable ally in diagnostic and surgical events. Trends in technical development indicate that we are entering an exciting era of advanced surgery of the human cerebrum, which is heralded by the following: 1) current developments in areas of imaging, sensors, and visualization; 2) new devices for localization and navigation; 3) new capabilities for action at the target point; and 4) innovative concepts related to advanced operative venues. Imaging has provided structurally based surgical maps, which now are being given the new dimension of function in complex and integrated formats for preoperative planning and intraoperative tactical direction. Cerebral localization and navigation based on these advances promise to provide further refinement to the field of stereotactic neurosurgery, as linked systems are superseded by more flexible nonlinked methodologies in functionally defined volume-oriented navigational databases. Target point action now includes not only ablative capabilities through micro-operative methods and the use of stereotactically directed high-energy forms but also the emergence of restorative capabilities through applications of principles of genetic engineering in the areas of molecular and cellular neurosurgery. Complex, dedicated, and self-contained operative venues will be required to optimize the emergence and development of these computer-oriented micro/stereotactic capabilities, which appear to be unavoidably required as locales for the practice and development of virtual reality-based stations for operative rehearsal, simulation, training, and, ultimately, enhancement of operative events through robotic interfaces. Primary impetus for progress has relied upon new combinations of technologies, disciplines, and industries. Philosophical and practical problems include the spectrum of availability of these methods to the population at large, the training of individuals to properly administer these methods, defining the acceptable envelope of expertise, and maintaining suitable delivery and progress while containing spiraling costs. Advanced neurological surgery and the use and development of high-technology adjuvants require a robust economy that has a populace willing to invest in the luxury of such developments. The current socioeconomic situation is fragile from the standpoint of both economics and attitudes of the patients and health care providers, with diversion of economic resources, redistribution of funding bases, modification of patient referrals, practice styles, and service attitudes undermining progress. Economic pressures have brought high-technology methods under great scrutiny regarding their effectiveness and cost-effectiveness. Reform proposals have specifically targeted technology-oriented services, and the Office of Technology Assessment has recommended increasing the use of managed care providers who look to information on cost-effectiveness and clinical practice guidelines to establish efficient management strategies and issue "report cards." Although the premise is laudable and "gimmickry" needs to be identified, it might be argued that such scrutiny and control might be overbearing and overused, impeding appropriate delivery and progress.

    Full Text Available Rorty invites us to abandon the belief that moral foundationalism of a universalist nature is useful for the moral progress of our societies. Instead, he suggests that post-modern secular liberalism and solidarity, understood as a local identification process and not as a universally binding principle, should be the axes of such progress. The present article will 1 clarify the redescription of solidarity made by Rorty, 2 show how such contingent redescription ends up being more useful for the attaining of solidarity that the foundationalist view, and 3 suggest an interpretation from which the self-empowerment between his notion of liberalism and the redescription of the concept of solidarity can be made evident.

  6. A framework for privacy and security analysis of probe-based traffic information systems

    KAUST Repository

    Canepa, Edward S.

    2013-01-01

    Most large scale traffic information systems rely on fixed sensors (e.g. loop detectors, cameras) and user generated data, this latter in the form of GPS traces sent by smartphones or GPS devices onboard vehicles. While this type of data is relatively inexpensive to gather, it can pose multiple security and privacy risks, even if the location tracks are anonymous. In particular, creating bogus location tracks and sending them to the system is relatively easy. This bogus data could perturb traffic flow estimates, and disrupt the transportation system whenever these estimates are used for actuation. In this article, we propose a new framework for solving a variety of privacy and cybersecurity problems arising in transportation systems. The state of traffic is modeled by the Lighthill-Whitham-Richards traffic flow model, which is a first order scalar conservation law with concave flux function. Given a set of traffic flow data, we show that the constraints resulting from this partial differential equation are mixed integer linear inequalities for some decision variable. The resulting framework is very flexible, and can in particular be used to detect spoofing attacks in real time, or carry out attacks on location tracks. Numerical implementations are performed on experimental data from the Mobile Century experiment to validate this framework. © 2013 ACM.

    Full Text Available De comunidade à metrópole: a biografia de São Paulo , was first published in 1954 and then re published in 1970 as Formação histórica de São Paulo: de comunidade à metrópole . Written by a young US researcher fascinated by Latin America, this material was originally submitted as his PhD thesis at Columbia University in 1952. Since then, Rich - ard Morse’s (1922-2001 work has come a long way and is now considered a primary reference in the history of urban development of São Paulo. This article briefly recovers the reader’s response when Morse’s research was first published, and how it ensured the book’s importance in the Brazilian historiography. The aim is to draw a parallel trajectory of the book and its author – the young researcher at Columbia who became a professor of Latin American History at Yale – and to discuss the meanings regarding its importance in São Paulo’s historiography as well as its contribution to a better understanding of the city.

    The United States Deep Submergence Facility is in the process of obtaining support for construction of a new manned submersible as a replacement for DSV Alvin. A new 6000+ meter manned submersible will provide U.S. scientists with access to an additional 35 per cent of the ocean floor including some currently unreachable portions of the U.S. EEZ. Researchers will have a vehicle designed for the missions currently conducted and those of the foreseeable future having the power and endurance to maximize the usefulness of available research time. They will have a more comfortable vehicle with a larger interior, improved viewport placement, greater battery capacity, and generally better able to handle the burgeoning scientific equipment requirements. Lastly they will have a vehicle that builds on the experience and improvements of 35 years that have made ALVIN the most successful research submersible in the world. The adaptability of the National Deep Submergence Facility (NDSF) to a wide variety of science needs is its strength, but this complexity can also confuse and intimidate new users. The NDSF maintains strong science liaison services and provides potential users with assistance throughout the process of cruise planning, proposal preparation, and execution of field programs. Procedures for gaining access to these vehicles are not difficult and potential users are assisted both directly by the NDSF personnel and also through a user group of scientists dedicated to providing the benefit of their experience. A successful mechanism for obtaining feedback between users and operator has been established through the Deep Submergence Science Committee (a UNOLS oversight committee) and the science community. Programs are selected for funding on a competitive basis through various federal funding agencies by standard agency review processes. DSV ALVIN and its support ship R/V ATLANTIS are owned by the U.S. Navy and operated under charter agreement with the Office of Naval Research. Operation of the NDSF remotely operated vehicle (ROV) assets can be arranged in a fly-away mode on appropriate vessels within the UNOLS fleet or on commercial vessels or foreign research vessels provided they are suitably equipped. Scheduling of the R/V ATLANTIS is arranged through UNOLS, as is the use of the ROVs on UNOLS ships. Coordination between funding agencies and the UNOLS scheduling process strives to provide the users with the optimal scheduling of the assets in a given year. Requests for at-sea use of these assets remain strong for the foreseeable future.

    Adhesions and poor healing are complications of flexor tendon repair. The purpose of this study was to investigate a tissue engineering approach to improve functional outcomes after flexor tendon repair in a canine model. Flexor digitorum profundus tendons were lacerated and repaired in 60 dogs that were followed for 10, 21, or 42 days. One randomly selected repair from either the second or fifth digit in one paw in each dog was treated with carbodiimide-derivatized hyaluronic acid, gelatin, and lubricin plus autologous bone marrow stromal cells stimulated with growth and differentiation factor 5; control repair tendons were not treated. Digits were analyzed by adhesion score, work of flexion, tendon-pulley friction, failure force, and histology. In the control group, 35 of 52 control tendons had adhesions, whereas 19 of 49 treated tendons had adhesions. The number of repaired tendons with adhesions in the control group was greater than the number in the treated group at all three times (p = 0.005). The normalized work of flexion in treated tendons was 0.28 (± 0.08), 0.29 (± 0.19), and 0.32 (± 0.22) N/mm/° at Day 10, Day 21, and Day 42 respectively, compared with the untreated tendons of 0.46 (± 0.19) at Day 10 (effect size, 1.5; p = 0.01), 0.77 (± 0.49) at Day 21 (effect size, 1.4; p < 0.001), and 1.17 (± 0.82) N/mm/° at Day 42 (effect size, 1.6; p < 0.001). The friction data were comparable to the work of flexion data at all times. The repaired tendon failure force in the untreated group at 42 days was 70.2 N (± 8.77), which was greater than the treated tendons 44.7 N (± 8.53) (effect size, 1.9; p < 0.001). Histologically, treated repairs had a smooth surface with intrinsic healing, whereas control repairs had surface adhesions and extrinsic healing. Our study provides evidence that tissue engineering coupled with restoration of tendon gliding can improve the quality of tendon healing in a large animal in vivo model. Tissue engineering may enhance intrinsic tendon healing and thus improve the functional outcomes of flexor tendon repair.

    An analytical investigation was made of two supersonic interceptor type airplanes to determine the most desirable turbojet engine characteristics for this application The airplanes were designed differently primarily because of the amount of subsonic flight incorporated in the flight plan--one flight having none and the other, a cruise radius of 400 nautical miles. Several power plant design variables were varied independently to determine the effect of changes in each parameter on airplane performance. These parameters included compressor pressure ratio, compressor efficiency, turbine-inlet temperature, afterburner temperature, engine specific weight, and air-handling capacity. The effects of using a convergent-divergent exhaust nozzle and of changing the design flight Mach number were also investigated.

    Lamure, C.

    1981-12-01

    The paper is divided into three parts illustrating three directions in traffic noise research. Studies on the effects of noise habitually involve surveys about people living close to highways, and these are discussed in the first part. There are still many difficulties in connecting the kinds and extent of disturbance people say they experience with traffic noise, but great hopes lie in the observation of behaviour. The accuracy in the descriptions of real exposure to noise becomes increasingly significant in the analyses of sleep disturbances. The bulk of the studies carried out so far has led to the definition of indices and thresholds for daytime disturbances but progress is still required in the field of night-time disturbances. The second part is about methods of prediction of traffic noise and some principles are recalled that tend to be overlooked in the current use of Leq. The use of other indices and studies on measure-accuracy would restore their significance to statistical approaches which must follow realistic laws of distribution of vehicle intervals and also of vehicle acoustical powers. Yet too much mathematical sophistication is often useless in common cases of application. The last part ddeals with noise reduction at source. Various prototypes of quiet trucks enable us to evaluate fairly correctly the costs and additional weights entailed by reductions of emissions of about 10 dB(A) when engines are encapsulated. The range of experiments on cars is not so wide but various operations in Europe are currently aiming at designing cars that would not emit more than 73-74 dB (instead of 80 dB(A) in the present regulations). Similarly, the methods and instrumentation to study engine noise have been greatly developed over the last five years. In conclusion it can be said that traffic noise has touched off widely diversified research involving various specialities. Metrology is comparatively less important than it used to be 15 years ago.

    Secure time transfer is critical for many timesensitive applications. the Global Positioning System (GPS) which is often used for this purpose has been shown to be susceptible to spoofing attacks. Quantum Key Distribution offers a way to securely generate encryption keys at two locations. Through careful use of this information it is possible to create a system that is more resistant to spoofing attacks. In this paper we describe our work to create a testbed which utilizes QKD and traditional RF links. This testbed will be used for the development of more secure and spoofing resistant time distribution protocols.

    The major threat caused to the authorised usage of Internet is Distributed Denial of Service attack. The mechanisms used to prevent the DDoS attacks are said to overcome the attack’s ability in spoofing the IP packets source addresses. By utilising Internet Protocol spoofing, the attackers cause a consequential load over the networks destination for policing attack packets. To overcome the IP Spoofing level on the Internet, We propose an Inter domain Packet Filter (IPF) architecture. The proposed scheme is not based on global routing information. The packets with reliable source addresses are not rejected, the IPF frame work works in such a manner. The spoofing capability of attackers is confined by IPF, and also the filter identifies the source of an attack packet by minimal number of candidate network.

  14. Face Liveness Detection Based on Skin Blood Flow Analysis

    Directory of Open Access Journals (Sweden)

    Shun-Yi Wang

    2017-12-01

    Full Text Available Face recognition systems have been widely adopted for user authentication in security systems due to their simplicity and effectiveness. However, spoofing attacks, including printed photos, displayed photos, and replayed video attacks, are critical challenges to authentication, and these spoofing attacks allow malicious invaders to gain access to the system. This paper proposes two novel features for face liveness detection systems to protect against printed photo attacks and replayed attacks for biometric authentication systems. The first feature obtains the texture difference between red and green channels of face images inspired by the observation that skin blood flow in the face has properties that enable distinction between live and spoofing face images. The second feature estimates the color distribution in the local regions of face images, instead of whole images, because image quality might be more discriminative in small areas of face images. These two features are concatenated together, along with a multi-scale local binary pattern feature, and a support vector machine classifier is trained to discriminate between live and spoofing face images. The experimental results show that the performance of the proposed method for face spoof detection is promising when compared with that of previously published methods. Furthermore, the proposed system can be implemented in real time, which is valuable for mobile applications.

  15. Introduction: commentaries and author's response to "The rise and fall of the autochthonous self: from Italian Renaissance Art and Shakespeare to Hediegger, Lacan, and Intersubjectivism" by Richard D. Chessick.

    Science.gov (United States)

    Leffert, Mark; Schwartz, Scott C; Chessick, Richard D

    2011-01-01

    This article addresses the unresolved question of the existence of a private core autochthonous self, as it has been described by Winnicott, Modell, and others. The postmodern version of the self has eliminated this concept entirely, relegating the self to a changing and unstable display, or regarding it as totally chaotic, or even an illusion. The question is raised whether by returning to the origins of this notion of a private self and then tracing its apparent dissolution it might be possible to discover some evidence that it still exists. The methodology used is that of obtaining knowledge directly through the arts and the claim is made that because empirical science has clamored to be the only source of knowledge, we have lost what could be obtained by direct intuitive seeing and experiencing the works of creative geniuses. To explore the rise of the autochthonous self this article provides an examination of the shift from Gothic art to Italian Renaissance art, a time which engendered the origin of "man" with his or her elusive private individual self that then became expressed in changing works of art. As this spread north, Shakespeare appeared and similarly invented and illustrated in his characters the private individual self, a concept not appreciated or recognized before the Renaissance. But as science arose and Western civilization began to decline, a corresponding disillusionment with "man" took place. The self began to be viewed as solely a social construction with no core except perhaps a genetic endowment. This was accompanied by a reduction in the concept of the human as a valuable and precious living being and was replaced by regarding the human as an object of control and exploitation. After the Second World War a movement in contemporary United States psychoanalysis gradually replaced the ideas of Freud and his emphasis on the "I" in the psychoanalytic process, with forms of relational therapy, assuming that the self was ab initio intersubjectively formed and could be altered fundamentally by focus on intersubjective processes. The author contends that this attitude makes it less likely for the psychoanalyst to focus on the regressive transferences from which derivatives of the private self arise and to grasp the phenomenological whole of the patient (p. 625).

    This report is a feasibility study for a biogas production unit adapted to a farm in Champtauroz in Switzerland, and a dual purpose power plant generating thermal and electric energy from the biogas according to the energy demand of the cheese factory attached to the farm. Typically 5*10{sup 5} m{sup 3} per year of biogas should be extracted from the manure of around 1,500 farm animals. The methane would be produced by a continuously operated digestor. The energy demand of the cheese factory, mainly thermal energy for the goat milk transformation process and electric power for the milk refrigeration, is measured in details and its annual profile is estimated. This demand is practically independent from the outdoor temperature as long as this temperature is higher than 10 {sup o}C. The report also includes a cost estimate for the whole project, functional schematics of the biogas production unit and of the power plant, and several diagrams displaying the heat and electric power demands of the cheese factory as a function of parameters like the cheese production and the quantity of refrigerated milk.

In doing so, she not only addresses a long overdue topic, but she also succeeds in elaborating it on a most abstract level. However, the formalistic consistency that the author uses to advance her research is ambivalent: on the one hand, the reduction of complexity bridges gaps between different disciplines, on the other hand, gender loses meaning if it is eventually subsumed under performance. Consequently, an outline of a general pedagogy, which omits the subject-constituting power of gender, emerges.

    Fingerprint recognition is one of the most widely used methods of biometrics. This method relies on the surface topography of a finger and, thus, is potentially vulnerable for spoofing by artificial dummies with embedded fingerprints. In this study, we applied the optical coherence tomography (OCT) technique to distinguish artificial materials commonly used for spoofing fingerprint scanning systems from the real skin. Several artificial fingerprint dummies made from household cement and liquid silicone rubber were prepared and tested using a commercial fingerprint reader and an OCT system. While the artificial fingerprints easily spoofed the commercial fingerprint reader, OCT images revealed the presence of them at all times. We also demonstrated that an autocorrelation analysis of the OCT images could be potentially used in automatic recognition systems.

    In today's security conscious society the efficiency of biometric systems has an increasing tendency to replace the classic but less effective keys and passwords. Hand geometry readers are popular biometrics used for acces control and time and attendance applications. One of their weaknesses is vulnerability to spoofing using fake hands (latex, play-doh or dead-hands). The object of this paper is to design a feature to be added to the hand geometry scanner in order to detect vitality in the hand, reducing the possibilities for spoofing. This paper demonstrates how the hand reader was successfully spoofed and shows the implementation of the vitality detection feature through an inexpensive but efficient electronic design. The method used for detection is photo-plethysmography. The Reflectance Sensor built is of original conception. After amplifying, filtering and processing the sensor's signal, a message is shown via an LCD display, concerning the liveness of the hand and the pulse rate.

    The VeriChip is a Radio-Frequency Identification (RFID) tag produced commercially for implantation in human beings. Its proposed uses include identification of medical patients, physical access control, contactless retail payment, and even the tracing of kidnapping victims. As the authors explain, the VeriChip is vulnerable to simple, over-the-air spoofing attacks. In particular, an attacker capable of scanning a VeriChip, eavesdropping on its signal, or simply learning its serial number can create a spoof device whose radio appearance is indistinguishable from the original. We explore the practical implications of this security vulnerability. The authors argue that:1 The VeriChip should serve exclusively for identification, and not authentication or access control. 2 Paradoxically, for bearer safety, a VeriChip should be easy to spoof; an attacker then has less incentive to coerce victims or extract VeriChips from victims' bodies.

    Using fingerprints as a method to identify an individual has been accepted in forensics since the nineteenth century, and the fingerprint has become one of the most widely used biometric characteristics. Most of the modern fingerprint recognition systems are based on the print pattern of the finger surface and are not robust against spoof attaching. We demonstrate a novel vital vascular fingerprint system using Doppler optical coherence tomography that provides highly sensitive and reliable personal identification. Because the system is based on blood flow, which only exists in a livng person, the technique is robust against spoof attaching.

    We examine the modal structure and dispersion of periodically nanostructured planar metallic cavities within the scattering matrix formulation. By nanostructuring a metallic grating in a planar cavity, artificial surface excitations or spoof plasmon modes are induced with dispersion determined by the periodicity and geometric characteristics of the grating. These spoof surface plasmon modes are shown to give rise to new cavity polaritonic modes at short mirror separations that modify the density of modes in nanostructured cavities. The increased modal density of states form cavity polarirons have a large impact on the fluctuation induced electromagnetic forces and enhanced hear transfer at short separations.

    In this study, a quasi-monochromatic photon tunneling peak has been achieved in substrate-comb-substrate three bodies system. The near-field tunneling peak results from coupling between spoof surface mode and cavity mode, which has been further amplified by three bodies effect. The spoof surface mode originates from phonon vibration, and is manipulated by the structure into new surface mode. As a non-contact approach to generate high intensity and narrow bandwidth tunneling mode, current study has many application points in near-field spectroscopy and energy-conversion.

    Denial of Service (DoS) attacks disable network services for legitimate users. A McAfee report shows that eight out of ten Critical Infrastructure Providers (CIPs) surveyed had a significant Distributed DoS (DDoS) attack in 2010.1 Researchers proposed many approaches for detecting these attacks in the past decade. Anomaly based DoS detection is the most common. In this approach, the detector uses statistical features; such as the entropy of incoming packet header fields like source IP addresses or protocol type. It calculates the observed statistical feature and triggers an alarm if an extreme deviation occurs. However, intrusion detection systems (IDS) using entropy based detection can be fooled by spoofing. An attacker can sniff the network to collect header field data of network packets coming from distributed nodes on the Internet and fuses them to calculate the entropy of normal background traffic. Then s/he can spoof attack packets to keep the entropy value in the expected range during the attack. In this study, we present a proof of concept entropy spoofing attack that deceives entropy based detection approaches. Our preliminary results show that spoofing attacks cause significant detection performance degradation.
