    Health technology management consists of several decision processes including the acquisition of new technology. The purchasing of a new device requires the selection of one among several products taking into account different criteria. When the technology is characterized by large amount of parameters the choice becomes problematical and a support tool is needed. In 2003 Sloane et al. published a study in which they demonstrated the potentialities of the Analytic Hierarchy Process (AHP) to support the selection of a biomedical instrumentation. The work presented here describes the application of AHP to support the quality assessment for the selection of pacemakers and implantable defibrillators and shows that the method is indeed very appropriate for that task.

  9. Philosophy of clinical psychopharmacology.

    2013-03-01

    The renewal of the philosophical debate in psychiatry is one exciting news of recent years. However, its use in psychopharmacology may be problematic, ranging from self-confinement into the realm of values (which leaves the evidence-based domain unchallenged) to complete rejection of scientific evidence. In this paper philosophy is conceived as a conceptual audit of clinical psychopharmacology. Its function is to criticise the epistemological and methodological problems of current neopositivist, ingenuously realist and evidence-servant psychiatry from within the scientific stance and with the aim of aiding psychopharmacologists in practicing a more self-aware, critical and possibly useful clinical practice. Three examples are discussed to suggest that psychopharmacological practice needs conceptual clarification. At the diagnostic level it is shown that the crisis of the current diagnostic system and the problem of comorbidity strongly influence psychopharmacological results, new conceptualizations more respondent to the psychopharmacological requirements being needed. Heterogeneity of research samples, lack of specificity of psychotropic drugs, difficult generalizability of results, need of a phenomenological study of drug-induced psychopathological changes are discussed herein. At the methodological level the merits and limits of evidence-based practice are considered, arguing that clinicians should know the best available evidence but that guidelines should not be constrictive (due to several methodological biases and rhetorical tricks of which the clinician should be aware, sometimes respondent to extra-scientific, economical requests). At the epistemological level it is shown that the clinical stance is shaped by implicit philosophical beliefs about the mind/body problem (reductionism, dualism, interactionism, pragmatism), and that philosophy can aid physicians to be more aware of their beliefs in order to choose the most useful view and to practice coherently

    An electroencephalogram (EEG) is a device for measuring and recording the electrical activity of brain. The EEG data of signal can be used as a source of analysis for human brain function. The purpose of this study was to design a portable multichannel EEG based on embedded system and ADS1299. The ADS1299 is an analog front-end to be used as an Analog to Digital Converter (ADC) to convert analog signal of electrical activity of brain, a filter of electrical signal to reduce the noise on low-frequency band and a data communication to the microcontroller. The system has been tested to capture brain signal within a range of 1-20 Hz using the NETECH EEG simulator 330. The developed system was relatively high accuracy of more than 82.5%. The EEG Instrument has been successfully implemented to acquire the brain signal activity using a PC (Personal Computer) connection for displaying the recorded data. The final result of data acquisition has been processed using OpenBCI GUI (Graphical User Interface) based through real-time process for 8-channel signal acquisition, brain-mapping and power spectral decomposition signal using the standard FFT (Fast Fourier Transform) algorithm.

    2017-04-01

    The development of an autonomous instrumentation for field research is always a challenge which needs knowledge and application of recent advances in technology and components production. Using this information a super-low power, low-cost, stand-alone GPS time synchronized data acquisition unit was created. It comprises an extended utilization of the microcontroller modules and peripherals and special firmware with flexible PLL parameters. The present report is devoted to a discussion of synchronization mode of data sampling in autonomous field instruments with possibility of GPS random breaks. In the result the achieved sampling timing accuracy is better than ± 60 ns without phase jumps and distortion plus fixed shift depending on the sample rate. The main application of the system is for simultaneous measurement of several channels from magnetic and electric sensors in field conditions for magneto-telluric instruments. First utilization of this system was in the new developed versions of LEMI-026 magnetometer and LEMI-423 field station, where it was applied for digitizing of up to 6 analogue channels with 32-bit resolution in the range ± 2.5V, digital filtration (LPF) and maximum sample rate 4kS/s. It is ready for record in 5 minutes after being turned on. Recently, this system was successfully utilized with the drone-portable magnetometers destined for the search of metallic objects, like UXO, in rural areas, research of engineering underground structure and for mapping ore bodies. The successful tests of drone-portable system were made and tests results are also discussed.

    Since 1998, when the laboratory of Medicinal Pharmacology was established in the Graduate School of Pharmaceutical Sciences, Osaka University, I have been interested in psychopharmacological research topics. During this period, we identified a number of novel regulatory mechanisms that control the prefrontal dopamine system through functional interaction between serotonin1A and dopamine D2 receptors or between serotonin1A and σ1 receptors. Our findings suggest that strategies that enhance the prefrontal dopamine system may have therapeutic potential in the treatment of psychiatric disorders. We also found that environmental factors during development strongly impact the psychological state in adulthood. Furthermore, we clarified the pharmacological profiles of the acetylcholinesterase inhibitors donepezil, galantamine, and rivastigmine, providing novel insights into their mechanisms of action. Finally, we developed the female encounter test, a novel method for evaluating motivation in mice. This simple method should help advance future psychopharmacological research. In this review, we summarize the major findings obtained from our recent studies in mice.

    1998-08-01

    SPID (SPeckle Imaging by Deconvolution) is a new speckle camera currently under construction at CRAL-Observatoire de Lyon. Its high spectral resolution and high image restoration capabilities open new astrophysical programs. The instrument SPID is composed of four main optical modules which are fully automated and computer controlled by a software written in Tcl/Tk/Tix and C. This software provides an intelligent assistance to the user by choosing observational parameters as a function of atmospheric parameters, computed in real time, and the desired restored image quality. Data acquisition is made by a photon-counting detector (CP40). A VME-based computer under OS9 controls the detector and stocks the data. The intelligent system runs under Linux on a PC. A slave PC under DOS commands the motors. These 3 computers communicate through an Ethernet network. SPID can be considered as a precursor for VLT's (Very Large Telescope, four 8-meter telescopes currently built in Chile by European Southern Observatory) very high spatial resolution camera.

  14. Psychopharmacology of Addiction

    Full Text Available Addiction is a primary, chronic, neurobiological disease, with genetic, psychosocial, and environmental factors influencing its development. Developments in the psychopharmacology of addiction is much slower than the other disciplines of psychiatry. For a long time, social and behavioral therapeutic approaches are the only choices for the treatment of addictive disorders. Disulfiram was the only pharmacological agent approved for addiction treatment until the end of 20th century. Pharmacological treatment options available for treatment have grown along with our understanding of the neurobiological mechanisms underlying the development and persistence of addiction. Several new medications like naltrexone, acamprosate, methadone and buprenoprhine have been approved for the treatment of alcohol and opioid use disorders ever since. Based on ever-increasing information about neurotransmitter and receptors, many studies have been performed concerning craving and relapse prevention in recent years. Besides many other pharmacological agents have been focus of new researches for treatment of different types of addiction. The aim of this article is to briefly review the literature on psychopharmacology of addictive disorders and recent developments in this area.

    1999-01-01

    Autism is a neurobiological disorder. The core clinical features of autism include impairment in social interaction, impairments in verbal and nonverbal communication, and restricted, repetitive, and stereotyped patterns of behavior, interests, and activities. Autism often has coexisting neuropsychiatric disorders, including seizure disorders, attention deficit hyperactivity disorder, affective disorders, anxiety disorder, obsessive-compulsive disorder, and Tourette disorder. No etiology-based treatment modality has been developed to cure individuals with autism. However, comprehensive intervention, including parental counseling, behavior modification, special education in a highly structured environment, sensory integration training, speech therapy, social skill training, and medication, has demonstrated significant treatment effects in many individuals with autism. Findings from preliminary studies of major neurotransmitters and other neurochemical agents strongly suggest that neurochemical factors play a major role in autism. The findings also provide the rationale for psychopharmacotherapy in individuals with autism. This article reviews studies of neurochemical systems and related psychopharmacological research in autism and related neuropsychiatric disorders. Clinical indications for pharmacotherapy are described, and uses of various medications are suggested. This article also discusses new avenues of investigation that may lead to the development of more effective medication treatments in persons with autism.

  20. Autonomous site selection and instrument positioning for sample acquisition

    Shaw, A.; Barnes, D.; Pugh, S.

    The European Space Agency Aurora Exploration Program aims to establish a European long-term programme for the exploration of Space, culminating in a human mission to space in the 2030 timeframe. Two flagship missions, namely Mars Sample Return and ExoMars, have been proposed as recognised steps along the way. The Exomars Rover is the first of these flagship missions and includes a rover carrying the Pasteur Payload, a mobile exobiology instrumentation package, and the Beagle 2 arm. The primary objective is the search for evidence of past or present life on mars, but the payload will also study the evolution of the planet and the atmosphere, look for evidence of seismological activity and survey the environment in preparation for future missions. The operation of rovers in unknown environments is complicated, and requires large resources not only on the planet but also in ground based operations. Currently, this can be very labour intensive, and costly, if large teams of scientists and engineers are required to assess mission progress, plan mission scenarios, and construct a sequence of events or goals for uplink. Furthermore, the constraints in communication imposed by the time delay involved over such large distances, and line-of-sight required, make autonomy paramount to mission success, affording the ability to operate in the event of communications outages and be opportunistic with respect to scientific discovery. As part of this drive to reduce mission costs and increase autonomy the Space Robotics group at the University of Wales, Aberystwyth is researching methods of autonomous site selection and instrument positioning, directly applicable to the ExoMars mission. The site selection technique used builds on the geometric reasoning algorithms used previously for localisation and navigation [Shaw 03]. It is proposed that a digital elevation model (DEM) of the local surface, generated during traverse and without interaction from ground based operators, can be

    Equipment financing by conditional sale, lease-purchase, and true lease transactions is discussed with emphasis on equity and third-party reimbursement. Use of available funds, bank loans, and leasing are compared on a quantitative basis with an incremental cash flow (ICF) analysis. The ICF analysis involves cash accrual and present value techniques. It is demonstrated in a parametric study of lease rates, equipment useful-lives, and reimbursement levels that leasing is the preferred financing route when there is an expectation of obsolescence and when lease term maturities are significantly less than equipment useful-life. Once the decision has been made to lease equipment, it is important to structure the transaction to achieve the optimum mix of rate, term, buy-out options, and available tax shelter. Specific lease situations are given to illustrate the problems that should be considered by the lessee. Lease terms and conditions tailored to the requirements of the users of biomedical instrumentation are discussed in detail. Lessor selection and the importance of a professional working relationship between lessee and lessor also are explored. The capabilities of the lessor (financial, technical, and administrative) can be tapped by the hospital/clinic staff to develop significant advantages in addition to the financing.

    Many research and teaching labs rely on USB data acquisition devices to collect voltage signals from instrumentation. However, these devices can be cost-prohibitive (especially when large numbers are needed for teaching labs) and require software to be developed for operation. In this article, we describe the development and use of an open-source USB data acquisition device (with 16-bit acquisition resolution) built using simple electronic components and an Arduino Uno that costs under $50. Additionally, open-source software written in Python is included so that data can be acquired using nearly any PC or Mac computer with a simple USB connection. Use of the device was demonstrated for a sophomore-level analytical experiment using GC and a CE-UV separation on an instrument used for research purposes.

    Cryogenic network for linear accelerator operations demand a large number of Cryogenic sensors, associated instruments and other control-instrumentation to measure, monitor and control different cryogenic parameters remotely. Here we describe an alternate approach of six types of newly designed integrated intelligent cryogenic instruments called device-servers which has the complete circuitry for various sensor-front-end analog instrumentation and the common digital back-end http-server built together, to make crateless PLC-free model of controls and data acquisition. These identified instruments each sensor-specific viz. LHe server, LN2 Server, Control output server, Pressure server, Vacuum server and Temperature server are completely deployed over LAN for the cryogenic operations of IUAC linac (Inter University Accelerator Centre linear Accelerator), New Delhi. This indigenous design gives certain salient features like global connectivity, low cost due to crateless model, easy signal processing due to integrated design, less cabling and device-interconnectivity etc.

    Schmied, Lori A; Steinberg, Hannah; Sykes, Elizabeth A B

    2006-05-01

    The role of experimental psychology in the development of psychopharmacology has largely been ignored in recent historical accounts. In this article the authors attempt to redress that gap by outlining work in early experimental psychology that contributed significantly to the field. While psychiatrists focused on the therapeutic nature of drugs or their mimicry of psychopathology, experimental psychologists used psychoactive drugs as tools to study individual differences in normal behavior as well as to develop methodologies using behavior to study mechanisms of drug action. Experimental work by Kraepelin, Rivers, and Hollingworth was particularly important in establishing drug-screening protocols still used today. Research on nitrous oxide and on the effects of drug combinations is discussed to illustrate the importance of experimental psychology to psychopharmacology.

    The development of a computerized instrumentation test plan (ITP) for the NASA/Ames Research Center National Full Scale Aerodynamics Complex (NFAC) is discussed. The objective of the ITP program was to aid the instrumentation engineer in documenting the configuration and calibration of data acquisition systems for a given test at any of four low speed wind tunnel facilities (Outdoor Aerodynamic Research Facility, 7 x 10, 40 x 80, and 80 x 120) at the NFAC. It is noted that automation of the ITP has decreased errors, engineering hours, and setup time while adding a higher level of consistency and traceability.

    Van Der Kolk, Bessel A.

    2001-01-01

    This paper reviews the currently available knowledge about the psychobiology and psychopharmacology of post-traumatic stress disorder (PTSD). It also reviews the various studies that have elucidated changes in brain function and structure in PTSD populations, including position emission tomography (PET), single photon emission computed tomography (SPECT), and event-related potential (ERP) studies. It then reviews the literature on catecholamine and hypothalamic-pituitary-adrenal (HPA) axis abnormalities in PTSD, and finally reviews the literature available on the psychopharmacology of PTSD. It discusses how the pathophysiology of PTSD determines the nature of psychopharmacological interventions. Psychopharmacological interventions in PTSD are largely limited to good studies on the effects of the selective serotonin reuptake inhibitors (SSRIs). In order to effectively intervene in PTSD, studies of other psychopharmacological agents are necessary, specifically of agents which affect limbic activation, decreased frontal lobe functioning, altered HPA activity, and other biological features of PTSD.

    1995-01-01

    Computer-based data acquisition systems play an important role in clinical monitoring and in the development of new monitoring tools. LabVIEW (National Instruments, Austin, TX) is a data acquisition and programming environment that allows flexible acquisition and processing of analog and digital data. The main feature that distinguishes LabVIEW from other data acquisition programs is its highly modular graphical programming language, "G," and a large library of mathematical and statistical functions. The advantage of graphical programming is that the code is flexible, reusable, and self-documenting. Subroutines can be saved in a library and reused without modification in other programs. This dramatically reduces development time and enables researchers to develop or modify their own programs. LabVIEW uses a large amount of processing power and computer memory, thus requiring a powerful computer. A large-screen monitor is desirable when developing larger applications. LabVIEW is excellently suited for testing new monitoring paradigms, analysis algorithms, or user interfaces. The typical LabVIEW user is the researcher who wants to develop a new monitoring technique, a set of new (derived) variables by integrating signals from several existing patient monitors, closed-loop control of a physiological variable, or a physiological simulator.

    The Landing and Impact Dynamics Branch of the NASA Langley Research Center has been conducting full-scale aircraft crash tests since the 1970s. Using a pendulum method, aircraft are suspended by cables from a 240-ft high gantry and swung into the impact surface at various attitudes and velocities. Instrumentation for these tests include on-board high-speed cameras, strain gages, load cells, displacement transducers, and accelerometers. Transducers in the aircraft are hard-wired through a long umbilical cable to the data acquisition room. Up to 96 channels of data can be collected at a typical rate of 4000 samples per second. Data acquisition using an FM multiplexed analog system and a high-speed personal computer based digital system is described.

    Highlights: • ENEA developed and characterized a first prototype of the In-Vessel Viewing System (IVVS) probe for ITER. • Piezo motor technology to be used in IVVS probe was tested in neutrons, gamma radiations, high temperature, vacuum and high magnetic fields. • A general architecture of the Data Acquisition and Control System (DACS) was defined and then specialized for each test. • The test campaign has validated instrumentation solutions, which can be effectively used in final IVVS implementation or other ITER diagnostics or applications. - Abstract: The In-Vessel Viewing System is a 3D laser scanning system which will be used to inspect the blanket first wall in ITER. To make the IVVS probe design compatible with the harsh environmental conditions present in ITER, a test campaign was performed in 2012–2013 to verify the adequacy of the main components of the IVVS probe. The IVVS components inspected were an optical encoder, passive components and two customized ultrasonic piezoceramic motors that were instrumented with various sensors. A general architecture of the Data Acquisition and Control System (DACS) was defined and then specialized for each test. To be suitable for this test campaign, the DACS had to host various I/O modules and to properly interface the driver of the customized piezo motors, in order to permit the full control of the test and the acquisition of experimental data. This paper presents the instrumentation solutions designed and implemented for different facilities constraints and the related DACS developed in four specialized versions for the described test campaign.

    Using conventional programming techniques for the production of data acquisition and control software can be a time-consuming procedure, and the code subsequently produced can often be inflexible and rather difficult to modify in the light of changing experimental requirements. A new generation of commercial software products have recently appeared which it is claimed can significantly reduce development times and give rise to more flexible code and improved user interfaces. An example of such a product is National Instruments' LabVIEW,'' which presents a novel graphical approach based on Apple Macintosh computer platforms. Extensive use of LabVIEW has been made by the Soft X-ray Group at Daresbury Laboratory over the past two years, and its performance is reported on here. Several examples of experimental arrangements for which it has been used are described, and an evaluation of the product is made.

    Latest Fusion energy experiments envision a quasi-continuous operation regime. In consequence, the largest experimental devices, currently in development, specify high-availability (HA) requirements for the whole plant infrastructure. HA features enable the whole facility to perform seamlessly in the case of failure of any of its components, coping with the increasing duration of plasma discharges (steady-state) and assuring safety of equipment, people, environment and investment. IPFN developed a control and data acquisition system, aiming for fast control of advanced Fusion devices, which is thus required to provide such HA features. The system is based on in-house developed Advanced Telecommunication Computing Architecture (ATCA) instrumentation modules - IO blades and data switch blades, establishing a PCIe network on the ATCA shelf's back-plane. The data switch communicates to an external host computer through a PCIe data network. At the hardware management level, the system architecture takes advantage of ATCA native redundancy and hot swap specifications to implement fail-over substitution of IO or data switch blades. A redundant host scheme is also supported by the ATCA/PCIe platform. At the software level, PCIe provides implementation of hot plug services, which translate the hardware changes to the corresponding software/operating system devices. The paper presents how the ATCA and PCIe based system can be setup to perform with the desired degree of HA, thus being suitable for advanced Fusion control and data acquisition systems. (authors)

    The intricate coupling between electrical and chemical activity in neural pathways of the central nervous system, and the implication of this coupling in neuropathologies, such as Parkinson's disease, motivates simultaneous monitoring of neurochemical and neuropotential signals. However, to date, neurochemical sensing has been lacking in integrated clinical instrumentation as well as in brain-computer interfaces (BCI). Here, we present an integrated system capable of continuous acquisition of data modalities in awake, behaving subjects. It features one channel each of a configurable neuropotential and a neurochemical acquisition system. The electrophysiological channel is comprised of a 40-dB gain, fully differential amplifier with tunable bandwidth from 140 Hz to 8.2 kHz. The amplifier offers input-referred noise below 2 muV rms for all bandwidth settings. The neurochemical module features a picoampere sensitivity potentiostat with a dynamic range spanning six decades from picoamperes to microamperes. Both systems have independent on-chip, configurable DeltaSigma analog-to-digital converters (ADCs) with programmable digital gain and resolution. The system was also interfaced to a wireless power harvesting and telemetry module capable of powering up the circuits, providing clocks for ADC operation, and telemetering out the data at up to 32 kb/s over 3.5 cm with a bit-error rate of less than 10(-5). Characterization and experimental results from the electrophysiological and neurochemical modules as well as the full system are presented.

    This report presents the high-resolution image acquisition and processing instrument for compound management applications (HIAPI-CM). The HIAPI-CM combines imaging spectroscopy and machine-vision analysis to perform rapid assessment of high-throughput screening (HTS) compound library quality. It has been customized to detect and classify typical artifacts found in HTS compound library microtiter plates (MTPs). These artifacts include (1) insufficient volume of liquid compound sample, (2) compound precipitation, and (3) colored compounds that interfere with HTS assay detection format readout. The HIAPI-CM is also configured to automatically query and compare its analysis results to data stored in a LIMS or corporate database, aiding in the detection of compound registration errors. To demonstrate its capabilities, several compound plates (n=5760 wells total) containing different artifacts were measured via automated HIAPI-CM analysis, and results compared with those obtained by manual (visual) inspection. In all cases, the instrument demonstrated high fidelity (99.8% empty wells; 100.1% filled wells; 94.4% for partially filled wells; 94.0% for wells containing colored compounds), and in the case of precipitate detection, the HIAPI-CM results significantly exceeded the fidelity of visual observations (220.0%). As described, the HIAPI-CM allows for noninvasive, nondestructive MTP assessment with a diagnostic throughput of about 1min per plate, reducing analytical expenses and improving the quality and stewardship of HTS compound libraries.

  15. Psychopharmacologic treatment of borderline personality disorder.

    2013-06-01

    The best available evidence for psychopharmacologic treatment of borderline personality disorder (BPD) is outlined here. BPD is defined by disturbances in identity and interpersonal functioning, and patients report potential medication treatment targets such as impulsivity, aggression, transient psychotic and dissociative symptoms, and refractory affective instability Few randomized controlled trials of psychopharmacological treatments for BPD have been published recently, although multiple reviews have converged on the effectiveness of specific anticonvulsants, atypical antipsychotic agents, and omega-3 fatty acid supplementation. Stronger evidence exists for medication providing significant improvements in impulsive aggression than in affective or other interpersonal symptoms. Future research strategies will focus on the potential role of neuropeptide agents and medications with greater specificity for 2A serotonin receptors, as well as optimizing concomitant implementation of evidence-based psychotherapy and psychopharmacology, in order to improve BPD patients' overall functioning.

  16. Digital data acquisition and preliminary instrumentation study for the F-16 laminar flow control vehicle

    1992-01-01

    Preliminary studies have shown that maintenance of laminar flow through active boundary-layer control is viable. Current research activity at NASA Langley and NASA Dryden is utilizing the F-16XL-1 research vehicle fitted with a laminar-flow suction glove that is connected to a vacuum manifold in order to create and control laminar flow at supersonic flight speeds. This experimental program has been designed to establish the feasibility of obtaining laminar flow at supersonic speeds with highly swept wing and to provide data for computational fluid dynamics (CFD) code calibration. Flight experiments conducted as supersonic speeds have indicated that it is possible to achieve laminar flow under controlled suction at flight Mach numbers greater than 1. Currently this glove is fitted with a series of pressure belts and flush mounted hot film sensors for the purpose of determining the pressure distributions and the extent of laminar flow region past the stagnation point. The present mode of data acquisition relies on out-dated on board multi-channel FM analogue tape recorder system. At the end of each flight, the analogue data is digitized through a long laborious process and then analyzed. It is proposed to replace this outdated system with an on board state-of-the-art digital data acquisition system capable of a through put rate of up to 1 MegaHertz. The purpose of this study was three-fold: (1) to develop a simple algorithm for acquiring data via 2 analogue-to-digital convertor boards simultaneously (total of 32 channels); (2) to interface hot-film/wire anemometry instrumentation with a PCAT type computer; and (3) to characterize the frequency response of a flush mounted film sensor. A brief description of each of the above tasks along with recommendations are given.

    The thirteenth biennial International Association of Geomagnetism and Aeronomy (IAGA) Workshop on Geomagnetic Observatory Instruments, Data Acquisition and Processing was held in the United States for the first time on June 9-18, 2008. Hosted by the U.S. Geological Survey's (USGS) Geomagnetism Program, the workshop's measurement session was held at the Boulder Observatory and the scientific session was held on the campus of the Colorado School of Mines in Golden, Colorado. More than 100 participants came from 36 countries and 6 continents. Preparation for the workshop began when the USGS Geomagnetism Program agreed, at the close of the twelfth workshop in Belsk Poland in 2006, to host the next workshop. Working under the leadership of Alan Berarducci, who served as the chairman of the local organizing committee, and Tim White, who served as co-chairman, preparations began in 2007. The Boulder Observatory was extensively renovated and additional observation piers were installed. Meeting space on the Colorado School of Mines campus was arranged, and considerable planning was devoted to managing the many large and small issues that accompany an international meeting. Without the devoted efforts of both Alan and Tim, other Geomagnetism Program staff, and our partners at the Colorado School of Mines, the workshop simply would not have occurred. We express our thanks to Jill McCarthy, the USGS Central Region Geologic Hazards Team Chief Scientist; Carol A. Finn, the Group Leader of the USGS Geomagnetism Program; the USGS International Office; and Melody Francisco of the Office of Special Programs and Continuing Education of the Colorado School of Mines. We also thank the student employees that the Geomagnetism Program has had over the years and leading up to the time of the workshop. For preparation of the proceedings, thanks go to Eddie and Tim. And, finally, we thank our sponsors, the USGS, IAGA, and the Colorado School of Mines.

  3. Design of bridge crane girder strain acquisition system based on virtual instrument

    Directory of Open Access Journals (Sweden)

    Wenxue LIU

    Full Text Available Girder is an important part of the bridge crane, which is also the main force element. In order to prevent accidents, it is necessary to collect the bridge crane girder stress data to analyse the fatigue life. This paper constructs a bridge crane girder strain acquisition system. The hardware system consists of sensors, connectors, data acquisition cards, wireless data transmission groups, POE power and host computer. The software system consists of NI MAX to interface with the computer's NI hardware and software resources,and LabVIEW programming to display and storage the girder strain data. Through this system, positions and working days strain data acquisition for the 50/10 t bridge crane girder gets the key positions strain data. The results show that the girder strain data acquisition system runs stably, channel signals of acquisition task transmit accurately, and the terminal data stores competely, meeting the detection requirements, which provides an important data support for the subsequent fatigue analysis and accurate remaining service life prediction of the crane girder.

    At present, the Mexican mint Salvia divinorum is an unregulated hallucinogen. This has resulted in various on-line botanical companies advertising and selling S. divinorum as a legal alternative to other regulated plant hallucinogens. It is predictable that its misuse will increase rapidly. The active ingredient in S. divinorum is the neoclerodane diterpene, salvinorin A (1a), which has been shown to be a kappa agonist both in vitro and in vivo. This review will cover the current state of research into the psychopharmacology of S. divinorum.

    SCK-CEN's research and development programme on instrumentation involves the assessment and the development of sensitive measurement systems used within a radiation environment. Particular emphasis is on the assessment of optical fibre components and their adaptability to radiation environments. The evaluation of ageing processes of instrumentation in fission plants, the development of specific data evaluation strategies to compensate for ageing induced degradation of sensors and cable performance form part of these activities. In 2000, particular emphasis was on in-core reactor instrumentation applied to fusion, accelerator driven and water-cooled fission reactors. This involved the development of high performance instrumentation for irradiation experiments in the BR2 reactor in support of new instrumentation needs for MYRRHA, and for diagnostic systems for the ITER reactor.

    Issues relating to informed consent and ethics in paediatric psychopharmacology limit research in this population. Children vary in their levels of cognitive development, and presence of psychiatric disorder may further impair their ability to give informed consent. In decisional impairment subjects, various methods used for consent are assent/dissent; inclusion of advance directives; and/or alternative decision-makers. India is emerging as a new market for clinical trials in recent years. Moreover, in India the sociocultural realities are different from those in the western countries making it necessary for professionals to be cautious in conducting drug trials. In this review, issues regarding informed consent in children and adolescent with psychiatric diagnosis are discussed for information, discussion and debate by professionals, parents, society and legal experts to create awareness and to facilitate development of guidelines that are appropriate and applicable to the Indian system.

    1990-08-01

    The beam instrumentation for LEP is comprised of a number of detectors such as current transformers, split-foil monitors, interaction and background monitors and electrostatic pickups. These instruments are interfaced using about 100 VME crates spread over 25 stations located around the 27 km circumference of LEP. The crates are connected to the control system using MIL/STD-1553, an Olivetti M380 running XENIX and an IBM token-ring. Each crate is equipped with a Themis TSVME106 CPU board which runs the Motorola RMS68K operating system kernel. A set of services (alarms, communications, I/O system, libraries, log book, timing, etc.) has been implemented and constitutes a comfortable environment for the application programs. Most of the programming is done in PASCAL, using a cross compiler developed and maintained at CERN. A set of utilities running in the Olivetti M380 and in the crates provides system monitoring, system and application reload, and surveillance of the behaviour of the system and of the application tasks.

    The CALIPSO Project (Caribbean Andesite Lava Island-volcano Precision Seismo-geodetic Observatory) has greatly enhanced the monitoring and scientific infrastructure at the Soufriere Hills Volcano, Montserrat with the recent installation of an integrated array of borehole and surface geophysical instrumentation at four sites. Each site was designed to be sufficiently hardened to withstand extreme meteorological events (e.g. hurricanes) and only require minimum routine maintenance over an expected observatory lifespan of >30 y. The sensor package at each site includes: a single-component, very broad band, Sacks-Evertson strainmeter, a three-component seismometer ( ˜Hz to 1 kHz), a Pinnacle Technologies series 5000 tiltmeter, and a surface Ashtech u-Z CGPS station with choke ring antenna, SCIGN mount and radome. This instrument package is similar to that envisioned by the Plate Boundary Observatory for deployment on EarthScope target volcanoes in western North America and thus the CALIPSO Project may be considered a prototype PBO installation with real field testing on a very active and dangerous volcano. Borehole sites were installed in series and data acquisition began immediately after the sensors were grouted into position at 200 m depth, with the first completed at Trants (5.8 km from dome) in 12-02, then Air Studios (5.2 km), Geralds (9.4 km), and Olveston (7.0 km) in 3-03. Analog data from the strainmeter (50 Hz sync) and seismometer (200 Hz) were initially digitized and locally archived using RefTek 72A-07 data acquisition systems (DAS) on loan from the PASSCAL instrument pool. Data were downloaded manually to a laptop approximately every month from initial installation until August 2003, when new systems were installed. Approximately 0.2 Tb of raw data in SEGY format have already been acquired and are currently archived at UARK for analysis by the CALIPSO science team.

    Thermal recovery methods are often applied to enhance oil recovery in heavy oil reservoirs, one of its challenges is to control the displacement of the thermal front. Methods are thus implemented to obtain data on the temperatures in the wells at any given time and to monitor other variables so that the behaviour of the thermal front can be predicted. The aim of this paper is to present a new control and instrumentation scheme to measure all of the variables. A software was created using Labview a graphs-based programming language software and PostgreSQL, a database management system. Using this software, sensors can be added or removed at any time; trends can be immediately visualized; and quality of the information is ensured since there is no human intervention in the data collection or processing. This paper presented a software which improves monitoring of all of the variables affecting the behaviour of the thermal front.

    2010-08-01

    There are clear limitations to the currently approved pharmacotherapies of depression, including the fact that they are all essentially monoamine-based, have modest efficacy and a relatively slow onset of efficacy, and suffer from significant tolerability issues, particularly in the long term, including sexual dysfunction, weight gain, and cognitive impairments. This article reviews some of the most promising novel mechanisms that are not represented in compounds currently approved for depression in either the United States or Europe and that may represent the future of the psychopharmacologic treatment of depression, potentially addressing some of the efficacy and tolerability issues of antidepressants on the market. These potential antidepressant treatments include the multimodal serotonergic agents, the triple uptake inhibitors, the neurokinin-based novel therapies, the glutamatergic treatments, the nicotinic receptor-based treatments, the neurogenesis-based treatments, and antiglucocorticoid therapies. Some of these mechanisms appear to be more advanced in terms of drug development than others, but they all contribute to the global effort to develop more effective and better tolerated treatments for major depressive disorder.

    Psychopharmacology is a powerful tool in psychiatry; however, it is one that demands responsibility in order to deal with the ethical complexities that accompany advances in the field. It is important that questions are asked and that ethical mindfulness and sensitivity are developed along with clinical skills. In order to cultivate and deepen ethical awareness and subsequently solve issues in optimal fashion, investment should be made in the development of an ethical decision-making process as well as in education in the ethics of psychopharmacology to trainees in the field at all stages of their educational development. A clear approach to identifying ethical problems, engaging various ethical concepts in considering solutions and then applying these principles in problem resolution is demanded. An openness in identifying and exploring issues has become crucial to the future development and maturation of psychopharmacologists, both research and clinical. Consideration must be given to the social implications of psychopharmacological practice, with the best interests of patients always paramount. From both a research and clinical perspective, psychopharmacology has to be practised with fairness, sensitivity and ethical relevance to all. While ethical issues related to psychopharmacological practice are varied and plentiful, this review focuses on advances in technology and biological sciences, personal integrity, special populations, and education and training.

    Full Text Available Abstract Research in psychopharmacology for children and adolescents is fraught with ethical problems and tensions. This has practical consequences as it leads to a paucity of the research that is essential to support the treatment of this vulnerable group. In this article, we will discuss some of the ethical issues which are relevant to such research, and explore their implications for both research and standard care. We suggest that finding a way forward requires a willingness to acknowledge and discuss the inherent conflicts between the ethical principles involved. Furthermore, in order to facilitate more, ethically sound psychopharmacology research in children and adolescents, we suggest more ethical analysis, empirical ethics research and ethics input built into psychopharmacological research design.

    A portable, multi-purpose Bio-instrumentation Amplifier and Data AcQuisition device (BADAQ) capable of measuring and transmitting EMG and EKG signals wirelessly via Bluetooth is designed and implemented. Common topologies for instrumentation amplifiers and filters are used and realized with commercially available, low-voltage, high precision operational amplifiers. An 8-bit PIC microcontroller performs 10-bit analog-to-digital conversion of the amplified and filtered signals and controls a Bluetooth transceiver capable of wirelessly transmitting the data to any Bluetooth enabled device. Electrical isolation between patient/subject, circuitry, and ancillary equipment is achieved by optocoupling components. The design focuses on simplicity, portability, and affordability.

  16. PET application in psychiatry and psychopharmacology

    Energy Technology Data Exchange (ETDEWEB)

    Suhara, Tetsuya [National Inst. of Radiological Sciences, Chiba (Japan)

    1999-07-01

    In the last few decades diagnostic and research tools in the medical field have made great advances, yet psychiatry has lacked sufficiently sensitive tools to measure the aberration of brain functions. Recently however, the development of Positron emission tomography (PET) techniques has made it possible to measure changes in neurochemical components in mental disorders and the effect of psychoactive drugs in living human brain. Most of the advancement in the psychiatric field has came from the development psychoactive drugs. Brain research involving identification of neurotransmission is largely based on compounds developed in psychopharmacology. Some of these compounds have been radiolabelled and used as radioligands for quantitative examination of neuroreceptors and other aspects of neurotransmission. Using PET, radioligand binding can now be examined in the human brain in vivo. PET techniques also allow examination of an unlabelled drug by examination of its interaction with a radioligand. So one potential of PET in psychiatry is to investigate the mechanism of psychoactive drugs. Antidepressants modulate serotonin transmission by inhibiting serotonin reuptake from the synaptic cleft. High affinity [{sup 3}H]imipramine binding sites in mammalian brain have been labelled to investigate serotonin transporters in living human brain by PET. Cyanoimipramine which is described as a potent serotonin reuptake inhibitor, was labelled with {sup 11}C. In a PET experiment with 6 healthy human subjects, a high accumulation of [{sup 11}C]cyanoimipramine was found in the thalamus and striatum and lowest accumulation was observed in the cerebellum, a region relatively void of serotonin transporters. The thalamus to cerebellum ratio was about 2 at 90 min after the injection of the tracer. Recently, [{sup 11}C]McN5652-X has been introduced as a better tracer for serotonin transporter imaging. Employing [{sup 11}C]McN5652-X in a PET study of 7 healthy human subjects, a high

    1994-01-01

    Subcritical cryogens such as liquid hydrogen (LH2) and liquid oxygen (LO2) are required for space based transportation propellant, reactant, and life support systems. Future long-duration space missions will require on-orbit systems capable of long-term cryogen storage and efficient fluid transfer capabilities. COLD-SAT, which stands for cryogenic orbiting liquid depot-storage acquisition and transfer, is a free-flying liquid hydrogen management flight experiment. Experiments to determine optimum methods of fluid storage and transfer will be performed on the COLD-SAT mission. The success of the mission is directly related to the type and accuracy of measurements made. The instrumentation and measurement techniques used are therefore critical to the success of the mission. This paper presents the results of the COLD-SAT experiment subsystem instrumentation and wire harness design effort. Candidate transducers capable of fulfilling the COLD-SAT experiment measurement requirements are identified. Signal conditioning techniques, data acquisition requirements, and measurement uncertainty analysis are presented. Electrical harnessing materials and wiring techniques for the instrumentation designed to minimize heat conduction to the cryogenic tanks and provide optimum measurement accuracy are listed.

    1986-02-01

    Although the scope of basic studies in psychopharmacology and psychobiology has been expanding steadily for about 30 years, relatively few clinical psychiatrists, psychologists, and psychopharmacologists now choose to become researchers or teachers in these disciplines. Such training is crucial to the future vitality of both academic and private-practice psychiatry, and in view of increasing constraints on training funds, student researchers may well be an endangered species. With these concerns in mind, at its 1984 meeting, the American College of Neuropsychopharmacology's Education and Training Committee organized a symposium of investigators, administrators, and former trainees to explore aspects of effective clinical research training in psychobiology and psychopharmacology. Aspects discussed included mentoring, settings and content of training, depth versus breadth of curriculum, and the effect of a critical mass of colleagues at various stages of professional development. Following a brief overview, selected panelists addressed the issues from their individual perspectives.

    The authors summarize two special sessions focused on the teaching of psychopharmacology at the 2003 and 2004 annual meeting of the American College of Neuropsychopharmacology (ACNP). The focus was on whether "improving the teaching-learning process" in psychiatric residency programs could improve clinical practice. Problems of strategies and pedagogic techniques that have been used were presented from multiple perspectives (e.g., from a dean, department chair, training director, and former students). There was a consensus that action involving psychopharmacology organizations and the American Association of Directors of Residency Training in Psychiatry (AADPRT) was necessary to improve "evidence-based" competencies before graduation and to follow prescribing patterns into clinical practice to determine whether the standards of care could be improved.

    The European Spallation Source (ESS) in Lund, Sweden is just entering the construction phase with 3 neutron instruments having started in its design concept phase in 2014. As a collaboration of 17 European countries the majority of hardware devices for neutron instrumentation will be provided in-kind. This presents numerous technical and organisational challenges for the construction and the integration of the instruments into the facility wide infrastructure; notably the EPICS control network with standardised hardware interfaces and the facilities absolute timing system. Additionally the new generation of pulsed source requires a new complexity and flexibility of instrumentation to fully exploit its opportunities. In this contribution we present a strategy for the modularity of the instrument hardware with well-defined standardized functionality and control & data interfaces integrating into EPICS and the facilities timing system. It allows for in-kind contribution of dedicated modules for each instrume...

    Research on psychopharmacological treatment in children and adolescents is the subject of ongoing ethical discussion, as minors with mental disorders constitute a vulnerable patient group. Considering the important legislative changes in pediatric research over the past decade in both the US and Western Europe, there is a need to review recent developments in this area. Based on a systematic literature review, a hermeneutical analysis focusing the main issues of ethics in child and adolescent psychopharmacology is provided. Legal and regulatory aspects of psychopharmacological research in children are compared between the US and Europe. Relevant issues were informed assent and consent to research participation, minimal risk and burden of research, ethics of pharmacogenetics, research on "me-too" medications, and justice in global research. Additionally, the concern about undue influence of financial interests in research is also addressed. Incentives for the conduct of clinical trials with children comparable to those contained in US legislation are now provided in the EU. Research to develop "me-too" preparations may have no significant benefit for children, but can cause research burden and detract from clinically more important projects by utilizing limited investigator time and patient resources. Thus far, pharmacogenetic studies may bring more individualized treatment approaches into child psychiatry but they remain at present a promise for the future. Finally, the issues of avoiding undue influence from funders and conflicts of interest remain a prominent concern which can be solved by declaring conflicts and publishing all results of studies extensively.

    The EMSODEV project (EMSO implementation and operation: DEVelopment of instrument module) is an Horizon-2020 UE project whose overall objective is the operation of eleven seafloor observatories and four test sites. These infrastructures are distributed throughout European seas, from the Arctic across the Atlantic and the Mediterranean to the Black Sea, and are managed by the European consortium EMSO-ERIC (European Research Infrastructure Consortium) with the participation of 8 European countries and other associated partners. Recently, we have implemented a Generic Sensor Module (EGIM) within the EMSO-ERIC distributed marine research infrastructure. EGIM is able to operate on any EMSO observatory node, mooring line, seabed station, cabled or non-cabled and surface buoy. The main role of EGIM is to measure homogeneously a set of core variables using the same hardware, sensor references, qualification methods, calibration methods, data format and access, maintenance procedures in several European ocean locations. The EGIM module acquires a wide range of ocean parameters in a long-term consistent, accurate and comparable manner from disciplines such as biology, geology, chemistry, physics, engineering, and computer science, from polar to subtropical environments, through the water column down to the deep sea. Our work includes developing standard-compliant generic software for Sensor Web Enablement (SWE) on EGIM and to perform the first onshore and offshore test bench, to support the sensors data acquisition on a new interoperable EGIM system. EGIM in its turn is linked to an acquisition drives processes, a centralized Sensor Observation Service (SOS) server and a laboratory monitor system (LabMonitor) that records events and alarms during acquisition. The measurements recorded along EMSO NODES are essential to accurately respond to the social and scientific challenges such as climate change, changes in marine ecosystems, and marine hazards.

  9. Issues of academic study and practical acquisition of Tuvan music (a case study of Tuvan instrumental music

    2017-06-01

    Full Text Available In the 20th century, Tuvan music culture has undergone dramatic upheaval and a number of transformations. Today we face an acute need to rethink the achievements and losses incurred over that period of time. The objective of this article is to reconsider some basic parameters of Tuvan music culture that are responsible for preserving the integrity of its sound structure. The relevance of the topic is due to a current conceptual rift between the musical practices and their scholarly interpretations. In the Soviet period, culture throughout the entire USSR was solely driven by the European model of musical development with no reliance on practices typical for ethnical cultures. We are currently witnessing a decline in the numbers of those representing oral and audial traditional culture, while the numbers of music college graduates, those who studied at conservatoires, universities, academies of culture and arts, and thus come as bearers of values lying outside of the tradition. Tuvan musical practice is experiencing an invasion of academic vocabulary and non-relevant appraisal criteria. However, Tuvan musical culture, having always been primarily oral, has developed its own acoustic structure, as well as mechanisms and methods for non-scriptory transfer of knowledge. But these vernacular methods are still insufficiently explored. The author postulates that the system of Tuvan instrumental music organization is unique and acts as a basis for unconventional sound of musical instruments and xöömei (throat singing. Distinctive timbre and inimitable flair of the sound is achieved by original system of bourdon-overtone sound coordination. Music is created for audial enjoyment. But musicologists (mainly in Russia are still analyzing the notation they keep making of performed folk instrumental pieces and xöömei. Such an approach drastically narrows the entire panorama of traditional instrumental music. A positive factor is that contemporary Tuvan

    Child and adolescent psychiatry is a relatively young field and the recognition, classification, and treatment of disorders in children and adolescents lag behind those in adults. In recent years there is an increasing awareness of the differences between children and adults in psychopathology and pharmacology. Related to this new paediatric regulations have been introduced. This article reviews the regulatory and legislative measures that were adopted in the EU in 2007 and the subsequent impact of these measures on the field of paediatric psychopharmacology. The consequences of the paediatric regulation in the EU are reflected in several domains: regulatory, research aimed at drug development and clinical practices. In the regulatory domain, the consequences include: new paediatric indications, inclusion of special (class) warnings, specification of dose regimens, and information on safety specific to children and adolescents, and development of new medicinal formulations. The paediatric regulation leads to timely development of paediatric friendly formulations and better quality of the clinical evidence. In clinical practices, an increased awareness of the uniqueness of paediatric pharmacology is emerging among medical professionals, and subsequent improvement of medical care (i.e. correct doses, appropriate formulation, monitoring for expected adverse events). In addition, clinical guidelines will have to be revised more frequently in order to integrate the recently acquired knowledge. The new regulations stimulate transparency and discussions between academia, pharmaceutical industry, and regulators. The purpose is to optimize clinical research and obtain evidence for paediatric psychopharmacology, thereby providing adequate support for treatment.

    1997-04-01

    A Holter-type, microprocessor-based, portable, in-shoe, plantar pressure data acquisition system has been developed. The system allows continuous recording of pressure data between the sole of the foot and the shoe during the performance of daily living activities. Fourteen conductive polymer sensors acquire the plantar pressure history, which is then stored in the system memory. Pressures are sampled at a rate of 40 Hz from each of the 14 sensors for up to 8 hrs. The extended recording and processing capacity of the system developed in this study allows quantitative analysis of cumulative plantar pressure and temporal gait data necessary for characterization of event-related alterations in plantar pressures. The alterations that could be examined with the system include rehabilitative, therapeutic, surgical, and nonsurgical treatment. The system is fully portable and does not disrupt the natural gait pattern of the subject during ambulation. Peak plantar pressures, pressure-time integrals, and contact durations are determined for each of the insole sensors.

  12. [Adherence to psychopharmacological treatment: Psychotherapeutic strategies to enhance adherence].

    2015-05-01

    Effective psychopharmacological medication with good tolerability represents the cornerstone of treatment for severe mental illness; however, the 1-year adherence rates are only approximately 50%. The term adherence emphasizes the collaborative responsibility of the clinician and the patient for a positive treatment outcome. Reasons for non-adherence are manifold and include patient-specific factors, such as self-stigmatization, lack of social and familial support, cognitive impairment and substance use besides insufficient effectiveness and the occurrence of side effects of the psychotropic drugs. To enhance adherence, both clinician and patient have to fully understand all the reasons for and against adherence to medication before a collaborative decision is made on future long-term treatment. A positive attitude towards medication critically depends on whether patients feel that the medication supports the attainment of the individual goals.

  13. The ethics of clinical innovation in psychopharmacology: Challenging traditional bioethics

    Directory of Open Access Journals (Sweden)

    Goodwin Frederick K

    2007-11-01

    Full Text Available Abstract Objective To assess the scientific and ethical basis for clinical innovation in psychopharmacology. Methods We conducted a literature review, utilizing MEDLINE search and bibliographic cross-referencing, and historical evidence regarding the discovery and development of new medications in psychiatry. Clinical innovation was defined as use of treatments in a clinical setting which have not been well-proven in a research setting. Results Empirical data regarding the impact of clinical innovation in psychopharmacology are lacking. A conceptual and historical assessment of this topic highlights the ethical and scientific importance of clinical innovation. Ethically, it touches a borderline that, in our judgment, is not adequately framed in contemporary mainstream bioethics. Currently, research is viewed as not at all benefiting the patients who participate in it, while clinical care is viewed as being solely for the benefit of patients. Clinical innovation straddles these two worlds, uncomfortably at times. While many argue that clinical innovation should either be avoided or folded into research projects, we argue that clinical innovation is necessary for progress in psychopharmacology research, and that it can prosper best when guided by the following ethical principles: 1. The treatment should be based on a viable hypothesis. 2. Whenever possible, one's clinical observations should be reported so they can be evaluated by the scientific community. 3. One should be willing to report unexpected observations of drug effects. 4. A high standard of informed consent should be maintained. Again, this proposal goes against the standard view among bioethicists that research and clinical care are categorically opposed activities, as made clear by the either-or dichotomy of the Belmont Report on bioethics. This approach has so polarized our profession into clinicians versus researchers, that many clinicians will not apply new knowledge produced by

    To obtain information on the use of psychotropic drugs children outside the U.S.A., 251 questionnaires were mailed to institutions in 53 countries. Seventy-three responses from 34 countries were analyzed. The percentage of patients receiving drugs under the care of these respondents ranged from 0 to 100% (mean 39%). A total of 56 different drugs were selected for eleven psychiatric disorders. No regional differences were apparent, except for infrequently used drugs. Respondents differed widely in the number of drugs selected and maximum dosages. The most popular drugs used in most disorders were diazepam, thioridazine, chlorpromazine, chlordiazepoxide, imipramine, amitriptyline, haloperidol and methylphenidate. Highest agreements among respondents were for imipramine in enuresis, diazepam in anxiety, chlorpromazine in psychosis and thioridazine in hyperkinesis. The results of this survey illustrate important problems in interpreting cross-cultural data in pediatric psychopharmacology, and recommendations for future research are made.

    The power of Ethernet for control and automation technology is being largely understood by the automation industry in recent times. Ethernet with HTTP (Hypertext Transfer Protocol) is one of the most widely accepted communication standards today. Ethernet is best known for being able to control through internet from anywhere in the globe. The Ethernet interface with built-in on-chip embedded servers ensures global connections for crate-less model of control and data acquisition systems which have several advantages over traditional crate-based control architectures for slow applications. This architecture will completely eliminate the use of any extra PLC (Programmable Logic Controller) or similar control hardware in any automation network as the control functions are firmware coded inside intelligent meters itself. Here, we describe the indigenously built project of a cryogenic control system built for linear accelerator at Inter University Accelerator Centre, known as "CADS," which stands for "Complete Automation of Distribution System." CADS deals with complete hardware, firmware, and software implementation of the automated linac cryogenic distribution system using many Ethernet based embedded cryogenic instruments developed in-house. Each instrument works as an intelligent meter called device-server which has the control functions and control loops built inside the firmware itself. Dedicated meters with built-in servers were designed out of ARM (Acorn RISC (Reduced Instruction Set Computer) Machine) and ATMEL processors and COTS (Commercially Off-the-Shelf) SMD (Surface Mount Devices) components, with analog sensor front-end and a digital back-end web server implementing remote procedure call over HTTP for digital control and readout functions. At present, 24 instruments which run 58 embedded servers inside, each specific to a particular type of sensor-actuator combination for closed loop operations, are now deployed and distributed across control LAN (Local

    The power of Ethernet for control and automation technology is being largely understood by the automation industry in recent times. Ethernet with HTTP (Hypertext Transfer Protocol) is one of the most widely accepted communication standards today. Ethernet is best known for being able to control through internet from anywhere in the globe. The Ethernet interface with built-in on-chip embedded servers ensures global connections for crate-less model of control and data acquisition systems which have several advantages over traditional crate-based control architectures for slow applications. This architecture will completely eliminate the use of any extra PLC (Programmable Logic Controller) or similar control hardware in any automation network as the control functions are firmware coded inside intelligent meters itself.

  18. Brave New World versus Island--utopian and dystopian views on psychopharmacology.

    Schermer, M H N

    2007-06-01

    Aldous Huxley's Brave New World is a famous dystopia, frequently called upon in public discussions about new biotechnology. It is less well known that 30 years later Huxley also wrote a utopian novel, called Island. This paper will discuss both novels focussing especially on the role of psychopharmacological substances. If we see fiction as a way of imagining what the world could look like, then what can we learn from Huxley's novels about psychopharmacology and how does that relate to the discussion in the ethical and philosophical literature on this subject? The paper argues that in the current ethical discussion the dystopian vision on psychopharmacology is dominant, but that a comparison between Brave New World and Island shows that a more utopian view is possible as well. This is illustrated by a discussion of the issue of psychopharmacology and authenticity. The second part of the paper draws some further conclusions for the ethical debate on psychopharmacology and human enhancement, by comparing the novels not only with each other, but also with our present reality. It is claimed that the debate should not get stuck in an opposition of dystopian and utopian views, but should address important issues that demand attention in our real world: those of evaluation and governance of enhancing psychopharmacological substances in democratic, pluralistic societies.

  19. The role of psychopharmacology in the medical abuses of the Third Reich: from euthanasia programmes to human experimentation.

    German psychiatry and pharmacology both enjoyed an extraordinary international reputation prior to the promulgation of the Third Reich. However, with the triumph of eugenic ideas and the imposition of a "racial hygiene" policy by the Nazi regime, various organs of the German health system saw themselves involved in a perverse system of social control, in which the illicit use of psychopharmacological tools became customary. In the present work, we review, from the historical perspective, the factors that helped to bring about this situation and we analyze the abuses (known and documented) committed through the specific use of psychotropic drugs during the Nazi period. Among such abuses we can identify the following illegitimate activities: the use of psychoactive drugs, mainly sedatives from the barbiturates family, in the different euthanasia programmes implemented by the Nazi authorities, in police activity and various types of repression, and for purely criminal and extermination purposes within the so-called "Final Solution"; psychopharmacological research on the mentally ill, without the slightest ethical requirements or legal justification; and the use of psychotropic agents in research on healthy subjects, recruited from concentration camps. Finally, we refer to the role of poisonous nerve agents (tabun, sarin and soman) as instruments of chemical warfare and their development by the German authorities. Many of these activities, though possibly only a small portion of the total - given the destruction of a great deal of documentation just before the end of World War II - came to light through the famous Nuremberg Trials, as well as through other trials in which specific persons were brought to justice unilaterally by individual Allied nations or by the authorities of the new German government after the War.

  20. Authenticity Anyone? The Enhancement of Emotions via Neuro-Psychopharmacology.

    Science.gov (United States)

    Kraemer, Felicitas

    2011-04-01

    This article will examine how the notion of emotional authenticity is intertwined with the notions of naturalness and artificiality in the context of the recent debates about 'neuro-enhancement' and 'neuro-psychopharmacology.' In the philosophy of mind, the concept of authenticity plays a key role in the discussion of the emotions. There is a widely held intuition that an artificial means will always lead to an inauthentic result. This article, however, proposes that artificial substances do not necessarily result in inauthentic emotions. The literature provided by the philosophy of mind on this subject usually resorts to thought experiments. On the other hand, the recent literature in applied ethics on 'enhancement' provides good reasons to include real world examples. Such case studies reveal that some psychotropic drugs such as antidepressants actually cause people to undergo experiences of authenticity, making them feel 'like themselves' for the first time in their lives. Beginning with these accounts, this article suggests three non-naturalist standards for emotions: the authenticity standard, the rationality standard, and the coherence standard. It argues that the authenticity standard is not always the only valid one, but that the other two ways of assessing emotions are also valid, and that they can even have repercussions on the felt authenticity of emotions. In conclusion, it sketches some of the normative implications if not ethical intricacies that accompany the enhancement of emotions.

  1. Psychopharmacological neuroprotection in neurodegenerative disease: assessing the preclinical data.

    This manuscript reviews the preclinical in vitro, ex vivo, and nonhuman in vivo effects of psychopharmacological agents in clinical use on cell physiology with a view toward identifying agents with neuroprotective properties in neurodegenerative disease. These agents are routinely used in the symptomatic treatment of neurodegenerative disease. Each agent is reviewed in terms of its effects on pathogenic proteins, proteasomal function, mitochondrial viability, mitochondrial function and metabolism, mitochondrial permeability transition pore development, cellular viability, and apoptosis. Effects on the metabolism of the neurodegenerative disease pathogenic proteins alpha-synuclein, beta-amyloid, and tau, including tau phosphorylation, are particularly addressed, with application to Alzheimer's and Parkinson's diseases. Limitations of the current data are detailed and predictive criteria for translational clinical neuroprotection are proposed and discussed. Drugs that warrant further study for neuroprotection in neurodegenerative disease include pramipexole, thioridazine, risperidone, olanzapine, quetiapine, lithium, valproate, desipramine, maprotiline, fluoxetine, buspirone, clonazepam, diphenhydramine, and melatonin. Those with multiple neuroprotective mechanisms include pramipexole, thioridazine, olanzapine, quetiapine, lithium, valproate, desipramine, maprotiline, clonazepam, and melatonin. Those best viewed circumspectly in neurodegenerative disease until clinical disease course outcomes data become available, include several antipsychotics, lithium, oxcarbazepine, valproate, several tricyclic antidepressants, certain SSRIs, diazepam, and possibly diphenhydramine. A search for clinical studies of neuroprotection revealed only a single study demonstrating putatively positive results for ropinirole. An agenda for research on potentially neuroprotective agent is provided.

    Seven topics previously described in this column are revisited. The use of quantitative electroencephalography has been shown in a prospective study to be effective for predicting antidepressant treatment response. A novel antidepressant drug, agomelatine, has generated much controversy, and its development for the U.S. market was discontinued. A long awaited revised system for categorizing the safety of medications during pregnancy and lactation has finally been published by the Food and Drug Administration. Dextromethorphan/quinidine, eslicarbazepine acetate, levomilnacipran, and esketamine are recent examples of drugs that were developed based on the complex concepts of chirality and stereochemistry. Lisdexamfetamine, a stimulant drug, failed to show benefit as an augmentation therapy for the treatment of depression. The combination drug naltrexone/bupropion was finally approved as a therapy for obesity, after its cardiovascular safety was confirmed in a prospective premarketing study. Further development of the glucocorticoid receptor antagonist drug mifepristone as a treatment for psychotic depression was stopped based on a large negative trial, but the drug continues to be investigated for other potential psychiatric indications. These examples illustrate how the field of psychopharmacology continues to evolve.

    2017-01-01

    Purpose To evaluate pathways through which sociodemographic, clinical, attitudinal, and perceived health control variables impact psychiatric patients’ adherence to psychopharmacological medications. Method A sample of 966 consecutive psychiatric outpatients was studied. The variables were sociodemographic (age, gender, and education), clinical (diagnoses, drug treatment, and treatment duration), attitudinal (attitudes toward psychopharmacological medication and preferences regarding participation in decision-making), perception of control over health (health locus of control, self-efficacy, and psychological reactance), and level of adherence to psychopharmacological medications. Structural equation modeling was applied to examine the nonstraightforward relationships and the interactive effects among the analyzed variables. Results Structural equation modeling demonstrated that psychiatric patients’ treatment adherence was associated: 1) negatively with cognitive psychological reactance (adherence decreased as cognitive psychological reactance increased), 2) positively with patients’ trust in their psychiatrists (doctors’ subscale), 3) negatively with patients’ belief that they are in control of their mental health and that their mental health depends on their own actions (internal subscale), and 4) positively (although weakly) with age. Self-efficacy indirectly influenced treatment adherence through internal health locus of control. Conclusion This study provides support for the hypothesis that perceived health control variables play a relevant role in psychiatric patients’ adherence to psychopharmacological medications. The findings highlight the importance of considering prospective studies of patients’ psychological reactance and health locus of control as they may be clinically relevant factors contributing to adherence to psychopharmacological medications.

    From the very outset of scientific Psychology, psychologists have shown interest for drugs and their effects on behavior. This has given rise to numerous contributions, mostly in the form of Psychopharmacology publications. The aim of this study was to quantitatively evaluate these contributions and compare them with other academic disciplines related to Psychopharmacology. Using the PubMed database, we retrieved information about articles from 15 journals included in the Pharmacology and Pharmacy category of the Journal Citation Reports database for a 21-year period (1987 to 2007). There were 37540 articles which about 52% were represented by 3 journals. About 70% of psychology publications were represented by 2 of these journals. Psychology departments accounted for the 11% of the published papers, which places Psychology third behind Psychiatry and Pharmacology, which contributed to 22.69 and 13% respectively. Psychology contributed to the greatest number of studies in 3 journals, second in 3 and third in 8. This report represents the first effort to explore the contribution of academic Psychology to the multidisciplinary science of psychopharmacology. Although leaders of production of psychopharmacology research were from Psychiatry and Pharmacology, Psychology departments are an important source of studies and thus of knowledge in the field of Psychopharmacology.

    There is increased interest in the role that ethnicity, sociocultural factors, and gender play in research, health care delivery, and response to intervention. The impact of these factors on AIDS awareness programs, on the phenomenology of suicide and anorexia nervosa, and on clinical psychopharmacology in a homogeneous population is discussed. Risky sex practices can be related to cultural norms that stigmatize condom use and sex education; economic deprivation; and male dominance. Gender, cultural, and ethnic demographics can identify high-risk groups as well as influence effective interventions. Suicide rates and risk factors are compared in African-American, Canadian Native, and South Korean adolescents. Academic stress was a differential risk factor for the Koreans. Anorexia nervosa predominantly affects women and has cultural differences in prevalence. The homogeneous population in Hong Kong illustrates the impact of ethnicity, sociocultural factors, and gender on clinical psychopharmacology. Attention to ethnicity, sociocultural factors, and gender can individualize and improve the effectiveness of clinical psychopharmacology.

    Assessment of autistic disorder (autism) symptoms, primary and secondary, poses more challenging problems than ordinarily found in multisite randomized clinical trial (RCT) assessments. For example, subjects may be uncommunicative and extremely heterogeneous in problem presentation, and current pharmacological treatments are not likely to alter most core features of autism. The Autism Research Units on Pediatric Psychopharmacology (RUPP Autism Network) resolved some of these problems during the design of a risperidone RCT in children/adolescents. The inappropriateness of the usual anchors for a Clinical Global Impression of Severity (CGI-S) was resolved by defining uncomplicated autism without secondary symptoms as a CGI-S of 3, mildly ill. The communication problems, compromising use of the patient as an informant, were addressed by several strategies, including careful questioning of care providers, rating scales, laboratory tests, and physical exams. The broad subject heterogeneity requires outcome measures sensitive to individual change over a wide spectrum of treatment response and side effects. The problems of neuropsychologically testing nonverbal, lower functioning, sometimes noncompliant subjects requires careful instrument selection/adaptation and flexible administration techniques. The problems of assessing low-end IQs, neglected by most standardized test developers, was resolved by an algorithm of test hierarchy. Scarcity of other autism-adapted cognitive and neuropsychological tests and lack of standardization required development of a new, specially adapted battery. Reliability on the Autism Diagnostic Interview (currently the most valid diagnostic instrument) and other clinician instruments required extensive cross-site training (in-person, videotape, and teleconference sessions). Definition of a treatment responder required focus on individually relevant target symptoms, synthesis of possible modest improvements in many domains, and acceptance of

    2013-03-01

    The discipline of psychiatry appears poised at the edge of a paradigm shift. Enthusiasm about psychopharmacological treatments and neuroscientific understandings is giving way to a sobering recognition of the limitations of current biologically oriented approaches. Psychiatry training programs have both an opportunity and a responsibility to address the challenges presented by the evidence. Although the average psychiatrist would profess a biopsychosocial ideal, an examination of our practice, journals, and training curricula suggests that we still have a long way to go before we employ a truly integrated model. There is a compelling, though oft-neglected evidence base demonstrating that pharmacologic treatment outcomes are as dependent on psychological and interpersonal factors as on medical ones. In order to maximize our usefulness to patients, psychiatry must embrace more complex and integrated understandings, transcending reductionistic models that promote mind-body splits. This article explores some of the costs of a model that places disproportionate emphasis on a biological framework. Relevant evidence bases are reviewed that demonstrate the utility of emphasizing the psychology of psychopharmacology. Implications for psychiatric training are considered, and suggestions are made for better integrating meaning factors into psychopharmacology education.

  19. Integration of Full Tensor Gravity and Z-Axis Tipper Electromagnetic Passive Low Frequency EM Instruments for Simultaneous Data Acquisition - Final Technical Report

    2016-12-02

    Ground gravity is a common and useful tool for geothermal exploration. Gravity surveys map density changes in the subsurface that may be caused by tectonic deformation such as faulting, fracturing, plutonism, volcanism, hydrothermal alteration, etc. Full Tensor Gravity Gradient (FTG) data has been used for over a decade in both petroleum and mining exploration to map changes in density associated with geologic structure. Measuring the gravity gradient, rather than the gravity field, provides significantly higher resolution data. Modeling studies have shown FTG data to be a viable tool for geothermal exploration, but no FTG data had been acquired for geothermal applications to date. Electromagnetic methods have been used for geothermal exploration for some time. The Z-Axis Tipper Electromagnetic (ZTEM) was a newer technology that had found success in mapping deep conductivity changes for mining applications. ZTEM had also been used in limited tests for geothermal exploration. This newer technology provided the ability to cost effectively map large areas whilst detailing the electrical properties of the geological structures at depths. The ZTEM is passive and it uses naturally occurring audio frequency magnetic (AFMAG) signals as the electromagnetic triggering source. These geophysical methods were to be tested over a known geothermal site to determine whether or not the data provided the information required for accurately interpreting the subsurface geologic structure associated with a geothermal deposit. After successful acquisition and analysis of the known source area, an additional survey of a “greenfield” area was to be completed. The final step was to develop a combined interpretation model and determine if the combination produced a higher confident geophysical model compared to models developed using each of the technologies individually.

    We developed a structure-property-activity relationship (SPAR)-model for psychopharmacological drugs acting as non-competitive 5-HT(3A) receptor antagonists by using a decision-tree learner provided by the RapidMiner machine learning tool. A single molecular descriptor, namely the molecular dipole moment per molecular weight (mu/MW), predicts whether or not a substance non-competitively antagonizes 5-HT-induced Na(+) currents. A low mu/MW is compatible with drug-cumulation in apolar lipid rafts. This study confirms that size-intensive descriptors allow the development of compact SPAR models.

    Contradictory views are expressed in the literature about the role played by serendipity in discoveries that led to modern psychopharmacology. This article attempts to resolve these contradictions by providing an operational definition of serendipity. The utility of the proposed definition is explored in the context of 18 discoveries. The results show that the most common pattern in the development of early psychiatric medications is serendipitous observation leading to non-serendipitous demonstration of clinical utility. The analysis also reveals examples of relatively pure serendipitous and non-serendipitous discoveries. The proposed definition appears to be reliable and valid.

    2013-01-01

    This article is an update of the algorithm for schizophrenia from the Psychopharmacology Algorithm Project at the Harvard South Shore Program. A literature review was conducted focusing on new data since the last published version (1999-2001). The first-line treatment recommendation for new-onset schizophrenia is with amisulpride, aripiprazole, risperidone, or ziprasidone for four to six weeks. In some settings the trial could be shorter, considering that evidence of clear improvement with antipsychotics usually occurs within the first two weeks. If the trial of the first antipsychotic cannot be completed due to intolerance, try another until one of the four is tolerated and given an adequate trial. There should be evidence of bioavailability. If the response to this adequate trial is unsatisfactory, try a second monotherapy. If the response to this second adequate trial is also unsatisfactory, and if at least one of the first two trials was with risperidone, olanzapine, or a first-generation (typical) antipsychotic, then clozapine is recommended for the third trial. If neither trial was with any these three options, a third trial prior to clozapine should occur, using one of those three. If the response to monotherapy with clozapine (with dose adjusted by using plasma levels) is unsatisfactory, consider adding risperidone, lamotrigine, or ECT. Beyond that point, there is little solid evidence to support further psychopharmacological treatment choices, though we do review possible options.

  4. 'Is getting well ever an art?': Psychopharmacology and madness in Robert Lowell's Day by Day.

    On the publication of Robert Lowell's Life Studies in 1959, some critics were shocked by the poet's use of seemingly frank autobiographical material, in particular the portrayal of his hospitalizations for bipolar disorder. During the late fifties and throughout the sixties, a rich vein, influenced by Lowell, developed in American poetry. Also during this time, the nascent science of psychopharmacology competed with and complemented the more established somatic treatments, such as psychosurgery, shock treatments, and psychoanalytical therapies. The development of Thorazine was a remarkable breakthrough allowing patients previously thought incurable to leave hospital. In 1955, the release of Miltown, the first 'minor' tranquilizer, was heralded with a media fanfare promising a new dawn of psychological cure-all. These two events blurred the boundary between 'normality' and madness by making treatment in the community more widely possible and by medicalizing more commonplace distress. Lowell's early depictions of madness situate it as emblematic of the cultural malaise of 'the tranquilized fifties.' By his final collection, Day by Day (1977), mental illness had lost its symbolic power. These late poems explore the power of art as a way of representing and remedying suffering in a culture where psychopharmacology has normalized madness.

    Although the use of psychotropic medications in child and adolescent psychiatry in Germany is on the increase, most compounds are in fact prescribed "off-label" because of a lack of regulatory approval in these age groups. In 2007, the European Parliament introduced Regulation 1901/2006 concerning medicinal products in pediatric populations, with a subsequent amendment in the form of Regulation 1902/2006. The main aim of this legislation was to encourage research and clinical trials in children and adolescents, and thus promote the availability of medications with marketing authorization for these age groups. Furthermore, initiatives such as the European 7th Framework Program of the European Union now offer substantial funding for pediatric pharmacological research. At a recent Congress of the German Society for Child and Adolescent Psychiatry and Psychotherapy (DGKJP), experts from the field and the pharmaceutical industry held a symposium with lay representatives in order to discuss attitudes toward, and experience with, pediatric psychopharmacology research in Germany since 2007. Several areas of concern were identified. The present paper derives from that symposium and provides an overview of these opinions, which remain crucial to the field. A wider discussion of how to facilitate psychopharmacological research in Germany in order to optimize the treatment and welfare of children and adolescents with psychiatric disorders is now warranted.

  6. Issues in the psychopharmacologic assessment and treatment of the orthodox Jewish patient.

    As with members of other cultural and religious groups, patients within the Orthodox Jewish community present with their own distinct clinical psychiatric issues related to their unique beliefs and practices. This article reviews the existing literature and anecdotal experience on the psychopharmacologic assessment and treatment of Orthodox Jewish patients. Specific aspects examined include this group's perceived intense stigma in receiving treatment, the priority this community places on cognitive functioning, and how the influence of Jewish laws on marriage and sexual practices impacts one's treatment decisions. The relevance of Jewish dietary laws, the Sabbath, and the community's interest in alternative treatments are also discussed. The limited ethno-psychopharmacology research related to Orthodox Jewish psychiatric patients is reviewed. We conclude that understanding issues such as these is critical if one is going to work within this cultural system in order to successfully address their mental health issues. However, the dearth of controlled research in this community needs to be addressed to provide more effective treatment.

    Full Text Available A lab-made interface for acquisition of instrumental analog signals between 0 and 5 V at a frequency up to 670 kHz at the parallel port of a microcomputer is described. Since it uses few and small components, it was built into the connector of a printer parallel cable. Its performance was evaluated by monitoring the signals of four different instruments and similar analytical curves were obtained with the interface and from readings from the instrument' displays. Because the components are cheap (~U$35,00 and easy to get, the proposed interface is a simple and economical alternative for data acquisition in small laboratories for routine work, research and teaching.

  14. Is the efficacy of psychopharmacological drugs comparable to the efficacy of general medicine medication?

    Directory of Open Access Journals (Sweden)

    Seemüller Florian

    2012-02-01

    Full Text Available Abstract There is an ongoing debate concerning the risk benefit ratio of psychopharmacologic compounds. With respect to the benefit, recent reports and meta-analyses note only small effect sizes with comparably high placebo response rates in the psychiatric field. These reports together with others lead to a wider, general critique on psychotropic drugs in the scientific community and in the lay press. In a recently published article, Leucht and his colleagues compare the efficacy of psychotropic drugs with the efficacy of common general medicine drugs in different indications according to results from reviewed meta-analyses. The authors conclude that, overall, the psychiatric drugs were generally not less effective than most other medical drugs. This article will highlight some of the results of this systematic review and discuss the limitations and the impact of this important approach on the above mentioned debate.

  15. Cost of treatment as a placebo effect in psychopharmacology: importance in the context of generic drugs.

    Science.gov (United States)

    Andrade, Chittaranjan

    2015-04-01

    Nonspecific factors have long been known in both psychotherapy and psychopharmacology. In recent years, 2 studies showed that placebo benefits were lower when the treated subjects were told that the placebo, presented as an active treatment, cost less. One of these studies had assessed motor and other outcomes in Parkinson disease patients; the other had assessed analgesia in paid, healthy volunteers to whom electric shocks were administered. The implication of the finding that lower treatment cost may diminish treatment gains is that patients who receive generic medicines may have lower expectations and may consequently derive less placebo-related benefit. This could be of concern in psychiatric disorders that are characterized by a large placebo response. Although the 2 "placebo cost" studies cannot be easily generalized to clinical and especially psychiatric contexts, clinicans should consider offering reassurance to patients receiving generic drugs that cost, per se, has no bearing on treatment-related benefit.

    Science.gov (United States)

    Wikinski, Silvia

    2008-01-01

    This work postulates the thesis that the development of the contemporary psychopharmacology, which began with the chemical changes imposed to molecules with antihistaminergic properties, modelled the current ethiopatogenic theories of mental diseases. The development of chlorpromazine and imipramine was coincident with the beginning of the research about neurotransmission. This coincidence contributed for the construction of the dopaminergic theory of schizophrenia and in the monoaminergic theory of depression. Limitations of the effectivity of current drugs, as observed in the trials CATIE and STAR-D may justify a change of perspective in the search for new molecular targets for the treatment of both diseases. Historical data are provided to illustrate the above mentioned thesis, in the perspective of two epistemological concepts: the context of discovery proposed by Hans Reichenbach and the epistemological obstacle, proposed by Gaston Bachelard.

    2011-12-01

    Research in the area of herbal psychopharmacology has increased markedly over the past decades. To date however, a comprehensive review of herbal antidepressant, anxiolytic and hypnotic psychopharmacology and applications in depression, anxiety and insomnia has been absent. A search of MEDLINE (PubMed), CINAHL, PsycINFO, and the Cochrane Library databases was conducted (up to February 21st 2011) on commonly used psychotropic herbal medicines. A review of the literature was conducted to ascertain mechanisms of action of these botanicals, in addition to a systematic review of controlled clinical trials for treatment of mood, anxiety and sleep disorders, which are common comorbid psychiatric disorders. Specific emphasis was given to emerging phytomedicines. Analysis of evidence levels was conducted, as were effect sizes (Cohen's d) where data were available. Results provided evidence of a range of neurochemical, endocrinological, and epigenetic effects for 21 individual phytomedicines, which are detailed in this paper. Sixty six controlled studies were located involving eleven phytomedicines. Several of these provide a high level of evidence, such as Hypericum perforatum for major depression, and Piper methysticum for anxiety disorders. Several human clinical trials provide preliminary positive evidence of antidepressant effects (Echium amoenum, Crocus sativus, and Rhodiola rosea) and anxiolytic activity (Matricaria recutita, Ginkgo biloba, Passiflora incanata, E. amoenum, and Scutellaria lateriflora). Caution should however be taken when interpreting the results as many studies have not been replicated. Several herbal medicines with in vitro and in vivo evidence are currently unexplored in human studies, and along with use of emerging genetic technologies "herbomics", are areas of potential future research.

  19. Changes in clinical trials methodology over time: a systematic review of six decades of research in psychopharmacology.

    André R Brunoni

    Full Text Available BACKGROUND: There have been many changes in clinical trials methodology since the introduction of lithium and the beginning of the modern era of psychopharmacology in 1949. The nature and importance of these changes have not been fully addressed to date. As methodological flaws in trials can lead to false-negative or false-positive results, the objective of our study was to evaluate the impact of methodological changes in psychopharmacology clinical research over the past 60 years. METHODOLOGY/PRINCIPAL FINDINGS: We performed a systematic review from 1949 to 2009 on MEDLINE and Web of Science electronic databases, and a hand search of high impact journals on studies of seven major drugs (chlorpromazine, clozapine, risperidone, lithium, fluoxetine and lamotrigine. All controlled studies published 100 months after the first trial were included. Ninety-one studies met our inclusion criteria. We analyzed the major changes in abstract reporting, study design, participants' assessment and enrollment, methodology and statistical analysis. Our results showed that the methodology of psychiatric clinical trials changed substantially, with quality gains in abstract reporting, results reporting, and statistical methodology. Recent trials use more informed consent, periods of washout, intention-to-treat approach and parametric tests. Placebo use remains high and unchanged over time. CONCLUSIONS/SIGNIFICANCE: Clinical trial quality of psychopharmacological studies has changed significantly in most of the aspects we analyzed. There was significant improvement in quality reporting and internal validity. These changes have increased study efficiency; however, there is room for improvement in some aspects such as rating scales, diagnostic criteria and better trial reporting. Therefore, despite the advancements observed, there are still several areas that can be improved in psychopharmacology clinical trials.

    2008-09-01

    Recent attention to the monoamine oxidase inhibiting properties of Banisteriopsis caapi's harmala alkaloids has precluded a balanced assessment of B. caapi's overall significance to indigenous South American societies. Relatively little attention has been paid to the cultural contexts, local meanings and patterns of use of B. caapi among snuff-using societies, such as the Piaroa, who do not prepare decoctions containing N,N-dimethyltryptamine (DMT) admixtures. This article reviews the psychopharmacological literature on B. caapi in light of recent ethnographic work conducted among the Piaroa of southern Venezuela. Piaroa shamans use only B. caapi's cambium, identify at least five distinct varieties of B. caapi, and emphasise the plant's importance for heightening empathy. Some Piaroa people also attribute a range of extra-shamanic uses to B. caapi, including as a stimulant and hunting aid. In light of the psychopharmacological complexity of harmala alkaloids, and ethnographic evidence for a wide range of B. caapi uses,future research should reconsider B. caapi's cultural heritage and psychopharmacological potential as a stimulant and antidepressant-like substance.

    Full Text Available Fragile X syndrome (FXS is associated with behavior that limits functioning, including distractibility, hyperactivity, impulsivity, hyperarousal, anxiety, mood dysregulation, and aggression. Medication response and side effect data were reviewed retrospectively for 257 patients (age 14±11 years, range 4–60 years, 203 M, 54 F attending an FXS clinic. Treatment success rates were defined as the percentage of positive response in the form of documented clinical report of improvement in the behavior(s being targeted over at least a 6-month period on the medication, without side effects requiring medication discontinuance, while failures were defined as discontinuance of medication due to lack of clinical effectiveness or side effects. Success rate for treatment of targeted behaviors with trials of individual medications was 55% for stimulants, 53% for antidepressants, 62% for alpha2-agonists, and 54% for antipsychotics. With sequential trials of different medications in the same class, success rate improved to 73–77%. Side effect-related failures were highest for antipsychotics. Systematic psychopharmacologic intervention targeted to behavioral symptoms appears helpful in the majority of patients with FXS.

    This revision of previous algorithms for the pharmacotherapy of generalized anxiety disorder was developed by the Psychopharmacology Algorithm Project at the Harvard South Shore Program. Algorithms from 1999 and 2010 and associated references were reevaluated. Newer studies and reviews published from 2008-14 were obtained from PubMed and analyzed with a focus on their potential to justify changes in the recommendations. Exceptions to the main algorithm for special patient populations, such as women of childbearing potential, pregnant women, the elderly, and those with common medical and psychiatric comorbidities, were considered. Selective serotonin reuptake inhibitors (SSRIs) are still the basic first-line medication. Early alternatives include duloxetine, buspirone, hydroxyzine, pregabalin, or bupropion, in that order. If response is inadequate, then the second recommendation is to try a different SSRI. Additional alternatives now include benzodiazepines, venlafaxine, kava, and agomelatine. If the response to the second SSRI is unsatisfactory, then the recommendation is to try a serotonin-norepinephrine reuptake inhibitor (SNRI). Other alternatives to SSRIs and SNRIs for treatment-resistant or treatment-intolerant patients include tricyclic antidepressants, second-generation antipsychotics, and valproate. This revision of the GAD algorithm responds to issues raised by new treatments under development (such as pregabalin) and organizes the evidence systematically for practical clinical application.

    2007-01-01

    The most outstanding novel of the Spanish literature, Don Quixote, represents the source to which the different specialists who intend to deepen their knowledge of the late Renaissance society usually address. This masterpiece of Miguel de Cervantes has been frequently approached from the psychopathological perspective to obtain a psychiatric diagnosis of its main character, Alonso Quijano. Also, other clinical approaches from the traumatological and general therapeutical view (oils, ointments, balms and other pharmacy preparations) have been frequent. We have tackled Don Quixote from the psychopharmacological perspective, a barely explored field. In this work, we intend to study the therapeutical cures used during the Cervantine time for the treatment of insane and mentally disturbed people (sedatives like opium, laxatives like hellebore, tonics, irritants and surgical techniques like bloodlettings and ) and we analyze the limited and unspecific therapies, mainly of herbal origin (balms, purgatives and emetics), which Cervantes reveals to us in his novel. Among them, rhubarb root (Rumex alpinus), seeds of spurge (Euphorbia lathyris), St. John's Wort (Hypericum perforatum), main ingredient of Aparicio's oil, and rosemary (Rosmarinus officinalis), primary component of the famous balsam of Fierabras, should be highlighted. We have also examined the possible scientific influences which might have inspired Cervantes in this field, mainly the works of Juan Huarte de San Juan The examination of men's wits and the one of Andres Laguna Dioscorides' materia medica.

    Seasonal affective disorder (SAD) is defined as a subtype of mood disorders in DSM 5, and it is characterized by a seasonal onset. SAD is proposed to be related to the seasonal changes in naturally occurring light, and the use of bright light therapy for depressive symptoms has been shown to reduce them in placebo controlled trials. Cognitive behavioral therapy has also been demonstrated to be effective in SAD. This review article aims to focus on the psychopharmacological treatment options for SAD. According to clinical trial results, first line treatment options seem to be sertraline and fluoxetine, and are well tolerated by the patients. There is some evidence that other antidepressants (e.g. bupropion) might be effective as well. Although clinical trials have shown that some of these antidepressants may be of benefit, a recent review has concluded that there is not enough evidence to support the use of any of these agents for the treatment of SAD yet. Moreover, more studies are still needed to evaluate the effectiveness of other treatment options, e.g., propranolol, melatonin, hypericum, etc. In addition to the above proposed treatments, patients with seasonal depressive symptoms should thoroughly be evaluated for any cues of bipolarity, and their treatment should be planned accordingly.

    The core symptoms of Autistic Spectrum Disorder (ASD) are impairment in reciprocal social interaction, communication, narrow interests, and stereotyped behaviour. These are frequently severe and persistent, although their severity may change over the course of life. Furthermore, the frequently associated symptoms of self-injury, aggressive behaviour, impulsivity, poor attention, anxiety, depression, and sleep disruption, can become a major source of additional distress and interference in functioning. The causes of autism are not yet known, but there is a general consensus that ASDs are highly heritable. Comprehension of the neurobiological basis for autism-spectrum disorders is still in its initial stages: a large body of research, however, has established ASD signs and symptoms are of neurological origin, and suggest that autism is a distributed neural system disorder, which disproportionately impairs many higher order abilities. Currently available medical treatments, primarily address co-morbid symptoms, rather than core symptoms. Thus, in spite of recent advances in psychopharmacology, the treatment approach still has important limits and shows poor efficacy on global outcomes. A potential pathway for improving clinical outcomes is that of the personalised treatment for autism, by using therapeutic drug monitoring (TDM) - a valuable tool for drugs with narrow therapeutic index - as well as systematic genetic background assessment, foreseen in future applications. However, it is already possible to implement an active surveillance programme to address safety concerns and to optimise therapeutic drug interventions in ASD.

  9. Psychopharmacological treatment and course in paranoid personality disorder: a case series.

    2013-09-01

    Little is known about the role of psychopharmacological treatment and course of illness in patients diagnosed with a paranoid personality disorder. This short communication provides a naturalistic study of a psychiatric hospital case series. Fifteen consecutive patients were retrospectively studied. The Clinical Global Impression was rated at first admission, at last psychiatric contact, and after a 6-week observation period with or without antipsychotic treatment. During psychiatric admissions, three patients improved markedly, eight showed only minor changes, and four worsened. In total, seven patients had been administered any antipsychotic medication. The median duration of treatment was 15 weeks (range 4 days-328 weeks). No major adverse effects were noted. Among patients with sixth-week observations available, four had received antipsychotics; they appeared to improve considerably compared with six patients who had not received antipsychotics. Although the findings should be interpreted with caution, they support the notion of the disorder being a relatively chronic condition, although antipsychotics appeared to be safe and possibly had an effect in the short term.

  10. Involvement of the endogenous opioid system in the psychopharmacological actions of ethanol: the role of acetaldehyde

    2013-07-01

    Full Text Available Significant evidence implicates the endogenous opioid system (opioid peptides and receptors in the mechanisms underlying the psychopharmacological effects of ethanol. Ethanol modulates opioidergic signaling and function at different levels, including biosynthesis, release, and degradation of opioid peptides, as well as binding of endogenous ligands to opioid receptors. The role of β-endorphin and µ-opioid receptors (OR have been suggested to be of particular importance in mediating some of the behavioral effects of ethanol, including psychomotor stimulation and sensitization, consumption and conditioned place preference. Ethanol increases the release of β-endorphin from the hypothalamic arcuate nucleus (NArc, which can modulate activity of other neurotransmitter systems such as mesolimbic dopamine. The precise mechanism by which ethanol induces a release of β-endorphin, thereby inducing behavioral responses, remains to be elucidated. The present review summarizes accumulative data suggesting that the first metabolite of ethanol, the psychoactive compound acetaldehyde, could participate in such mechanism. Two lines of research involving acetaldehyde are reviewed: 1 implications of the formation of acetaldehyde in brain areas such as the NArc, with high expression of ethanol metabolizing enzymes and presence of cell bodies of endorphinic neurons and 2 the formation of condensation products between DA and acetaldehyde such as salsolinol, which exerts its actions via OR.

    The standard randomized controlled trial design is still based on the acute disease model. This is in sharp contrast with the fact that the patient is likely to have experienced other treatments before, that may actually modify clinical course and responsiveness. The current standard of therapeutic trial in psychiatry is represented by the large, multi-center, controlled randomized trial with broad inclusion criteria, and little attention to other factors such as the clinical history of patients and comorbidity. The heterogeneous features of these patients would then affect the outcome of the trial. Conflicting results among randomized controlled trials can represent a spectrum of outcomes, based on different patient groups, more than bias or random variability. If a treatment is tested by a series of small trials with inclusion criteria for specific characteristics (including treatment history, subgroups and comorbidity), we may have a better knowledge of its indications and contraindications. Further, there is increasing need of expanding the content of customary clinical information, by including evaluation of variables such as stress, lifestyle, well-being, illness behavior and psychological symptoms. These joint strategies would actually constitute a paradigm shift in psychopharmacology and psychotherapy research. Copyright © 2012 Elsevier Inc. All rights reserved.

    Study designs involving medication-free intervals have become the subject of controversy in the current dialogue on the ethics of serious mental-illness research. Schizophrenia patients ( n=59; response rate 75%; 48% inpatients) and psychiatrists ( n=70; response rate 83%) responded to ten questions about a hypothetical scenario in which a schizophrenia study participant experienced the re-emergence of serious symptoms during the "wash-out" phase of a psychopharmacological trial. Patients provided their personal views, and psychiatrists gave their personal views and made predictions as to how schizophrenia patients in general would respond. Schizophrenia patients and psychiatrists judged the hypothetical protocol as moderately harmful. Both expressed relatively low likelihood of willingness to participate in the study, given this potential outcome. Schizophrenia patients and psychiatrists found the decision fairly easy. Psychiatrists underestimated the level of harm and overestimated the difficulty of the decision as perceived by schizophrenia patients. Schizophrenia patients acknowledged that the offer of money and request by their doctor or family would increase the likelihood of their participation, and psychiatrists accurately predicted these responses. In hypothetical decisions about the symptomatic study participant, 38% of patients and 39% of psychiatrists said they would allow him to leave the hospital. A majority of both groups (63% and 52%, respectively) indicated that medication should be given despite the study participant's objection. Psychiatrists incorrectly predicted this response, expecting instead that most schizophrenia patients would support the discharge request and few would support involuntary administration of medication. Patients and psychiatrists offered similar reasons for participation decisions but differed in their strategies for handling the situation. These findings suggest potential strengths of decisionally capable schizophrenia

  15. Assessment of language acquisition.

    de Villiers, Peter A; de Villiers, Jill G

    2010-03-01

    This review addresses questions of what should be assessed in language acquisition, and how to do it. The design of a language assessment is crucially connected to its purpose, whether for diagnosis, development of an intervention plan, or for research. Precise profiles of language strengths and weaknesses are required for clear definitions of the phenotypes of particular language and neurodevelopmental disorders. The benefits and costs of formal tests versus language sampling assessments are reviewed. Content validity, theoretically and empirically grounded in child language acquisition, is claimed to be centrally important for appropriate assessment. Without this grounding, links between phenomena can be missed, and interpretations of underlying difficulties can be compromised. Sensitivity and specificity of assessment instruments are often assessed using a gold standard of existing tests and diagnostic practices, but problems arise if that standard is biased against particular groups or dialects. The paper addresses the issues raised by the goal of unbiased assessment of children from diverse linguistic and cultural backgrounds, especially speakers of non-mainstream dialects or bilingual children. A variety of new approaches are discussed for language assessment, including dynamic assessment, experimental tools such as intermodal preferential looking, and training studies that assess generalization. Stress is placed on the need for measures of the process of acquisition rather than just levels of achievement. Copyright © 2010 John Wiley & Sons, Ltd.

    Psychopharmacological investigations of the subjective state of being and the reactivity pattern of a group of 14 probands show a good agreement with the alterations of performance reported in the first part of this publication and with the data on polarity profiles. In addition to a sedative effect the interaction of alcohol and oxazepam in the oxazepam trial results in dysphoric changes of mood and related significant alterations of polarity profiles. A correlation of the changes of performance and the alterations of the polarity profiles with the respective blood levels of alcohol and oxazepam could be demonstrated.

  17. The psychopharmacology algorithm project at the Harvard South Shore Program: an algorithm for acute mania.

    Science.gov (United States)

    Mohammad, Othman; Osser, David N

    2014-01-01

    This new algorithm for the pharmacotherapy of acute mania was developed by the Psychopharmacology Algorithm Project at the Harvard South Shore Program. The authors conducted a literature search in PubMed and reviewed key studies, other algorithms and guidelines, and their references. Treatments were prioritized considering three main considerations: (1) effectiveness in treating the current episode, (2) preventing potential relapses to depression, and (3) minimizing side effects over the short and long term. The algorithm presupposes that clinicians have made an accurate diagnosis, decided how to manage contributing medical causes (including substance misuse), discontinued antidepressants, and considered the patient's childbearing potential. We propose different algorithms for mixed and nonmixed mania. Patients with mixed mania may be treated first with a second-generation antipsychotic, of which the first choice is quetiapine because of its greater efficacy for depressive symptoms and episodes in bipolar disorder. Valproate and then either lithium or carbamazepine may be added. For nonmixed mania, lithium is the first-line recommendation. A second-generation antipsychotic can be added. Again, quetiapine is favored, but if quetiapine is unacceptable, risperidone is the next choice. Olanzapine is not considered a first-line treatment due to its long-term side effects, but it could be second-line. If the patient, whether mixed or nonmixed, is still refractory to the above medications, then depending on what has already been tried, consider carbamazepine, haloperidol, olanzapine, risperidone, and valproate first tier; aripiprazole, asenapine, and ziprasidone second tier; and clozapine third tier (because of its weaker evidence base and greater side effects). Electroconvulsive therapy may be considered at any point in the algorithm if the patient has a history of positive response or is intolerant of medications.

  18. Investigation of serotonin-1A receptor function in the human psychopharmacology of MDMA.

    Serotonin (5-HT) release is the primary pharmacological mechanism of 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') action in the primate brain. Dopamine release and direct stimulation of dopamine D2 and serotonin 5-HT2A receptors also contributes to the overall action of MDMA. The role of 5-HT1A receptors in the human psychopharmacology of MDMA, however, has not yet been elucidated. In order to reveal the consequences of manipulation at the 5-HT1A receptor system on cognitive and subjective effects of MDMA, a receptor blocking study using the mixed beta-adrenoreceptor blocker/5-HT1A antagonist pindolol was performed. Using a double-blind, placebo-controlled within-subject design, 15 healthy male subjects were examined under placebo (PL), 20 mg pindolol (PIN), MDMA (1.6 mg/kg b.wt.), MDMA following pre-treatment with pindolol (PIN-MDMA). Tasks from the Cambridge Neuropsychological Test Automated Battery were used for the assessment of cognitive performance. Psychometric questionnaires were applied to measure effects of treatment on core dimensions of Altered States of Consciousness, mood and state anxiety. Compared with PL, MDMA significantly impaired sustained attention and visual-spatial memory, but did not affect executive functions. Pre-treatment with PIN did not significantly alter MDMA-induced impairment of cognitive performance and only exerted a minor modulating effect on two psychometric scales affected by MDMA treatment ('positive derealization' and 'dreaminess'). Our findings suggest that MDMA differentially affects higher cognitive functions, but does not support the hypothesis from animal studies, that some of the MDMA effects are causally mediated through action at the 5-HT1A receptor system.

    Cao, Shuai; Chen, Xiang

    2014-01-01

    A portable instrument for arteriosclerosis assessment containing sensor module, acquisition board and embedded module was developed for home care in this paper. The sensor module consists of one ECG module and three pulse wave extraction modules, synchronously acquiring human ECG and pulse wave signal of carotid, radial, and dorsal, respectively. The acquisition board converts the sensor module's analog output signals into digital signals and transmits them to the embedded module. The embedded module realizes the functions including signal display, storage and the calculation and output of pulse wave velocity. The structure of the proposed portable instrument is simple, easy to use, and easy to expand. Small size, low cost, and low power consumption are also the advantages of this device. Experimental results demonstrated that the proposed portable instrument for arteriosclerosis assessment has high accuracy, good repeatability and can assess the degree of atherosclerosis appropriately.

    NERSC recently undertook a project to access and analyze Secure Shell (SSH) related data. This includes authentication data such as user names and key fingerprints, interactive session data such as keystrokes and responses, and information about noninteractive sessions such as commands executed and files transferred. Historically, this data has been inaccessible with traditional network monitoring techniques, but with a modification to the SSH daemon, this data can be passed directly to intrusion detection systems for analysis. The instrumented version of SSH is now running on all NERSC production systems. This paper describes the project, details about how SSH was instrumented, and the initial results of putting this in production.

    The evidence shows that borderline personality disorder (BPD) is the most frequently diagnosed personality disorder. However, the diagnostic criteria are very heterogeneous, suggesting that very different patients may be included within a single construct. Despite its severity, there are no standardized treatments for this group of patients. We find the same problem in the Acute Mental Health Services. The numerous proposals that have been put forward are unclear and have not reached a final consensus. According to Oldham's classification, BPD can be divided into the following subtypes: Affective, Impulsive, Aggressive, Empty and Dependent. In this paper, we propose a psychotherapeutic initial approach from the Dialectical Behavioral Therapy (DBT) perspective and an initial psychopharmacological approach for each subtype of BPD.

    These guidelines from the British Association for Psychopharmacology address the scope and targets of pharmacological treatment for schizophrenia. A consensus meeting, involving experts in schizophrenia and its treatment, reviewed key areas and considered the strength of evidence and clinical implications. The guidelines were drawn up after extensive feedback from the participants and interested parties, and cover the pharmacological management and treatment of schizophrenia across the various stages of the illness, including first-episode, relapse prevention, and illness that has proved refractory to standard treatment. The practice recommendations presented are based on the available evidence to date, and seek to clarify which interventions are of proven benefit. It is hoped that the recommendations will help to inform clinical decision making for practitioners, and perhaps also serve as a source of information for patients and carers. They are accompanied by a more detailed qualitative review of the available evidence. The strength of supporting evidence for each recommendation is rated.

    2002-01-01

    Autism is an early developmental disorder. It leads to severe and durable disturbances. Given this problem, no treatment can be excluded a priori. Thus, many approaches are used to deal with autistic disorders. In France, pharmacological treatments are, for instance, largely and mostly used in adults. In the USA, these treatments concern 50% of persons with autism of any age. Nevertheless, they are rarely based on controlled studies. At the present, however, prescriptions and expected effects appear to be hard to localize. Furthermore, only few controlled studies validate their use. Aim - We offer a review of studies about medical treatments used in adolescents and adults with autism. They are classified in 3 categories: the first (category I) includes drugs used for their neurochemical effects focusing on autistic signs. The second (category II) covers drugs used for treatment of behavioural disorders frequently associated with autism. The third (category III) corresponds to a wide range of drugs or vitamins for wich only few case studies exist reporting irregular positive effects. The main hypothesis of this review is that autism involves a dysfunction of the neuromediation systems. This hypothesis opens new perspectives in the research of medical treatments in autism by focusing on molecules, which are supposed to have an effect on neuromediation systems. Method - Our review is based on studies, which have been published during the past twenty years. For many studies, data are limited to adolescents and adults. So we expanded our review to data available in children. The data bases that we have used are medline and psyclit. Keywords have been chosen according to: pharmacological considerations (psychotropic, psychoactive drugs, psychopharmacology) and clinical symptoms (autism, automutilations, aggressive behavior, and hyperactivity). Hypothesis of a dysfunction in the neuromediation systems in autism - Many studies exist about biochemical abnormalities in

    Every normal child acquires a language in just a few years. By 3- or 4-years-old, children have effectively become adults in their abilities to produce and understand endlessly many sentences in a variety of conversational contexts. There are two alternative accounts of the course of children's language development. These different perspectives can be traced back to the nature versus nurture debate about how knowledge is acquired in any cognitive domain. One perspective dates back to Plato's dialog 'The Meno'. In this dialog, the protagonist, Socrates, demonstrates to Meno, an aristocrat in Ancient Greece, that a young slave knows more about geometry than he could have learned from experience. By extension, Plato's Problem refers to any gap between experience and knowledge. How children fill in the gap in the case of language continues to be the subject of much controversy in cognitive science. Any model of language acquisition must address three factors, inter alia: 1. The knowledge children accrue; 2. The input children receive (often called the primary linguistic data); 3. The nonlinguistic capacities of children to form and test generalizations based on the input. According to the famous linguist Noam Chomsky, the main task of linguistics is to explain how children bridge the gap-Chomsky calls it a 'chasm'-between what they come to know about language, and what they could have learned from experience, even given optimistic assumptions about their cognitive abilities. Proponents of the alternative 'nurture' approach accuse nativists like Chomsky of overestimating the complexity of what children learn, underestimating the data children have to work with, and manifesting undue pessimism about children's abilities to extract information based on the input. The modern 'nurture' approach is often referred to as the usage-based account. We discuss the usage-based account first, and then the nativist account. After that, we report and discuss the findings of several

    Design techniques of an automatic control system implementing corrected kerma determination and shutter command in the calibration laboratory at IPEN are shown, as well as the periodic calibration program developed for a monitor chamber for several X-ray beam qualities used for diagnostic radiology and radiation protection instruments. Two reference electrometers, a multichannel secondary standard thermometer, and an absolute pressure barometer were connected to the Rs-232 interface from a PC computer equipped with a National Instruments multi function analog and digital I/O card. LabVIEW{sup MR} was chosen as programming tool, which allowed for the development of a suite of programs for both controlling the shutter timing cycles and the calibration of the monitor chamber against a reference standard. A detailed description of the methods used for troubleshooting, fine tuning of parameters and evaluation of program results is followed by an analysis showing that considerable advantages regarding reduction of time and precision improvements during the calibrations could be achieved by the use of the developed programs, particularly under adverse conditions like those found during short expositions, or instead during long irradiation intervals where fluctuation of parameters like kerma rate or room conditions (temperature or pressure) can be found.

    Linear position sensitive detectors (PSDs) are widely used to configure neutron diffractometers and other instruments. Necessary front-end electronics and a data acquisition system [1] is developed to cater to such instruments built around the Dhruva research reactor in BARC. These include three diffractometers with multiple PSDs and four with single PSD. The front-end electronics consists of high voltage units, preamplifiers [2], shaping amplifiers, ratio ADCs (RDC) [3]. The data acquisition system consists of an interface card and software. Commercially available hardware like temperature controller or stepper motor controller connected over GPIB or RS232 are also integrated in the data acquisition system. The data acquisition is automated so that it can continue unattended for control parameter like temperature, thus enabling optimum utilization of available beam time. The instrumentation is scalable and can be easily configured for various instrumental requirements. The front-end electronics and the data acquisition system are described here.

    An evidence base for the treatment of mania and bipolar depression with psychotic symptoms is lacking. Nevertheless, clinicians may have a preference for treating episodes of bipolar disorder with or without psychotic symptoms in different ways, which is likely to reflect notions of differential efficacy of treatments between these subtypes. This study aimed to investigate whether the psychopharmacological treatment of psychotic and non-psychotic episodes of mania and bipolar depression, respectively, differs in clinical practice. We conducted a register-based study assessing the psychopharmacological treatment of all individuals receiving their first diagnosis of mania or bipolar depression between 2010 and 2012. The psychopharmacological treatment within 3 months following the time of diagnosis was considered. Potential differences in psychopharmacological treatment between the psychotic and non-psychotic subtypes of mania and bipolar depression, respectively, were investigated by means of Pearson's χ(2) test and logistic regression adjusted for sex and age at diagnosis of bipolar disorder. A total of 827 patients were included in the analyses. The adjusted odds ratio (aOR) for treatment with an antipsychotic was 1.71 (95% confidence interval [CI]: 1.18-2.48, Pbipolar depression. The aOR for treatment with the combination of an antipsychotic and an anticonvulsant was 1.60 (95% CI: 1.06-2.43, Pbipolar psychotic depression. It would be of interest to conduct studies evaluating whether antipsychotics represent the superior pharmacological treatment for psychotic mania and psychotic bipolar depression. © 2017 John Wiley & Sons A/S.

The IPOD is intended to be bolted to the top of Dual-Use Casks stored at Baikal-1 in Kazakhstan in order to maintain continuity of knowledge of the materials stored within the cask. The data acquisition system receives pulses from the neutron-detection preamp, combines this information with other sensor data, and stores the result on two SD cards that are part of the data acquisition system. Firmware in the data acquisition system controls collection and storing of the data and enables configuration of the acquisition parameters.

    Patients experiencing mental disorders are at an elevated risk for developing aggressive behavior. In the past 10 years, the psychopharmacological treatment of aggression has changed dramatically owing to the introduction of atypical antipsychotics on the market and the increased use of anticonvulsants and lithium in the treatment of aggressive patients.This review (second of 2 parts) uses a translational medicine approach to examine the neurobiology of aggression, discussing the major neurotransmitter systems implicated in its pathogenesis (serotonin, glutamate, norepinephrine, dopamine, and γ-aminobutyric acid) and the neuropharmacological rationale for using atypical antipsychotics, anticonvulsants, and lithium in the therapeutics of aggressive behavior. A critical review of all clinical trials using atypical antipsychotics (aripiprazole, clozapine, loxapine, olanzapine, quetiapine, risperidone, ziprasidone, and amisulpride), anticonvulsants (topiramate, valproate, lamotrigine, and gabapentin), and lithium are presented. Given the complex, multifaceted nature of aggression, a multifunctional combined therapy, targeting different receptors, seems to be the best strategy for treating aggressive behavior. This therapeutic strategy is supported by translational studies and a few human studies, even if additional randomized, double-blind, clinical trials are needed to confirm the clinical efficacy of this framework.

  14. Confidence-Based Feature Acquisition

    Science.gov (United States)

    Wagstaff, Kiri L.; desJardins, Marie; MacGlashan, James

    2010-01-01

    Confidence-based Feature Acquisition (CFA) is a novel, supervised learning method for acquiring missing feature values when there is missing data at both training (learning) and test (deployment) time. To train a machine learning classifier, data is encoded with a series of input features describing each item. In some applications, the training data may have missing values for some of the features, which can be acquired at a given cost. A relevant JPL example is that of the Mars rover exploration in which the features are obtained from a variety of different instruments, with different power consumption and integration time costs. The challenge is to decide which features will lead to increased classification performance and are therefore worth acquiring (paying the cost). To solve this problem, CFA, which is made up of two algorithms (CFA-train and CFA-predict), has been designed to greedily minimize total acquisition cost (during training and testing) while aiming for a specific accuracy level (specified as a confidence threshold). With this method, it is assumed that there is a nonempty subset of features that are free; that is, every instance in the data set includes these features initially for zero cost. It is also assumed that the feature acquisition (FA) cost associated with each feature is known in advance, and that the FA cost for a given feature is the same for all instances. Finally, CFA requires that the base-level classifiers produce not only a classification, but also a confidence (or posterior probability).

    2009-06-01

    Compulsive hoarding (the acquisition of and failure to discard large numbers of possessions) is associated with substantial health risk, impairment, and economic burden. However, little research has examined separate components of this definition, particularly excessive acquisition. The present study examined acquisition in hoarding. Participants, 878 self-identified with hoarding and 665 family informants (not matched to hoarding participants), completed an Internet survey. Among hoarding participants who met criteria for clinically significant hoarding, 61% met criteria for a diagnosis of compulsive buying and approximately 85% reported excessive acquisition. Family informants indicated that nearly 95% exhibited excessive acquisition. Those who acquired excessively had more severe hoarding; their hoarding had an earlier onset and resulted in more psychiatric work impairment days; and they experienced more symptoms of obsessive-compulsive disorder, depression, and anxiety. Two forms of excessive acquisition (buying and free things) each contributed independent variance in the prediction of hoarding severity and related symptoms.

    Chemists may be required to setup, troubleshoot, repair and sometimes construct the instruments they use for analytical measurements. Many students are intimidated when first "looking under the hood" of a modern instrument. This curriculum was devised to provide hands-on experience with the theory and design of modern instruments. A background in electronics is considered fundamental to this goal. This course extensively utilizes LabVIEW to economically provide basic electronic instrumentation and to serve in data acquisition and manipulation for a student design project. LabVIEW provides many built-in functions including a graphical user interface (GUI) and has universal acceptance in research and manufacturing settings. Programming is accomplished by placing and connecting icons that represent various functions. Virtual instruments produced by combining data acquisition boards with the language are functional equivalent to their real counterparts. The course culminates in construction of a computer-controlled electrochemical instrument capable of cyclic voltammetry and anodic stripping experiments.

    Gamma-ray holdup measurements of a Mossbauer spectroscopy instrument are described and modeled. In the qualitative acquisitions obtained in a low background area of Savannah River National Laboratory, only Am-241 and Np-237 activity were observed. The Am-241 was known to be the instrumental activation source, while the Np-237 is clearly observed as a source of contamination internal to the instrument. The two sources of activity are modeled separately in two acquisition configurations using two separate modeling tools. The results agree well, demonstrating a content of (1980 {+-} 150) {mu}Ci Am-241 and (110 {+-} 50) {mu}Ci of Np-237.

    The research work on Web-based long-distance data acquisition (DAQ) is valuable for application to tele-detection machine faults. With an expert system for machine fault detection, faults in a distantly located machine can be diagnosed through the internet. The distant user logs on to the expert system Web page, fills in the requirements, and starts-up the diagnose process. The system then connects to the DAQ server that is installed in the machine, samples data required for diagnoses through the internet, and sends back diagnose results. In such a long-distance system, Web-based DAQ plays an important role by automatic sampling and transferring of data through the internet. We have built an experimental data acquisition system using a National Instruments AT-MIO-16E-10 board running under Ch language environment. In this experimental example, the user can acquire data online. The principle of this experimental method is introduced in this paper. A detailed programming technique is described with an example.

    2009-01-01

    Full Text Available Multispectral acquisition of artworks has recently received considerable attention in the image processing community. Quite understandably, so far this attention has mainly focused on paintings, given their predominant role in museum collections. It is worth pointing out that the instrumentation and procedures used for acquiring regular paintings are not suited for the multispectral acquisition of large-sized painted surfaces such as frescoed halls and great paintings. Given the relevance of such artifacts, and their widespread presence in churches or historical buildings due to their social function, the problem of finding suitable techniques for their acquisition is certainly worth addressing. This paper focuses on multispectral acquisition of large-sized pictorial surfaces, systematically addressing the practical issues related to the acquisition equipment and procedure. Given the crucial role played by the illumination in this application, special attention is given to this issue. The proposed approach is supported by experimental results.

    Attention deficit hyperactivity disorder (ADHD) is a common condition with a high societal burden. The present guidelines summarise current literature, generating expert consensus recommendations for the treatment of ADHD in children and adults. These guidelines also provide a review of recent research in the fields of neuroimaging, neuropsychology and genetics of ADHD. Novel discoveries in these areas have informed physiological models for the disease. Since the publication of the previous British Association for Psychopharmacology guidelines in 2008, new drugs have been licensed and further compounds are being investigated. The publication of randomised controlled trials of psychological interventions has contributed to the range of treatment options for ADHD. As the disorder has been diagnosed more frequently there has been greater focus on comorbid conditions and how they impact treatment. Services have continued to develop for the treatment of ADHD in adults and care agreements have been introduced to facilitate access to treatment.

    Full Text Available Parent management training programme was prepared by Research Units on Pediatric Psychopharmacology and Psychosocial Interventions (RUPP Autism Network based on ABA (Applied Behavior Analysis. The programme aims to prevent or decrease the problem behavior and to bring the children with autism in positive behaviors by educating their families. The controlled randomized clinical research of RUPP has determined that Parent Managament Training (PMT have provided meaningful improvements on childrens’ function and family relationships. The group of children on which risperidone and PMT have implemented together had statistically meaningful improvements such as increase in adaptive skills and decrease in the aggressive behaviors when compared with the children who used only risperidone. There is no such programme in Turkey for the families with children in pervasive developmet disorder. This paper aims to introduce and show the potentials of the PMT programme that has been developed by RUPP Autism Network.

    2003-09-01

    No standard treatment exists for the DSM-IV Impulse Control Disorders, Not Elsewhere Classified, including Compulsive Buying Disorder. This paper reviews the suggested pharmacotherapies for this disorder and their theoretical basis. McElroy et al. first reported benefit from antidepressant therapy in three cases of Compulsive Buying Disorder with comorbid depression and anxiety. In a retrospective chart review, McElroy's group reported on 20 patients that benefited from antidepressants, often in combination with mood stabilizers. Lejoyeux reported on two patients in whom treatment of a comorbid mood disorder led to remission of compulsive buying behavior. Black reported fluvoxamine to be effective in patients without comorbid major depression, suggesting that improvement was independent of the treatment of mood symptoms. Kim reported improvement with naltrexone, an opioid antagonist, in a case series. Two double-blind placebo-controlled trials found fluvoxamine no better than placebo; however, in both studies patients kept shopping logs, which may have confounded the results. An open-label trial of citalopram and a double-blind crossover trial which excluded shopping logs both reported positive results. Twelve-month follow-up data for the open-label group found that remission rates at quarterly time points were independent of continuing drug therapy. The data reviewed above suggest that pharmacologic interventions may be effective for compulsive buying disorder. Whether pharmacological treatment is superior to placebo and whether it is more, less or equally effective compared to psychotherapeutic interventions remains to be established.

  9. Serendipity and psychopharmacology.

    Science.gov (United States)

    Howland, Robert H

    2010-10-01

    This article describes several examples where the development of drugs and devices for use in psychiatry followed from initial serendipitous observations. The potential psychotropic properties of chlorpromazine (Thorazine(®)) were first noted in surgical patients when the drug was being investigated as a potentiator of anesthesia. Similar findings were noted with iproniazid (Marsilid(®)), developed for the treatment of tuberculosis, and the drug was later released for clinical use as an antidepressant agent. The development of meprobamate (Miltown(®)), an approved treatment for anxiety, evolved from initial efforts to find a chemical that would inhibit the enzymatic destruction of the antibiotic drug penicillin. The psychiatric uses of lamotrigine (Lamictal(®)) and vagus nerve stimulation were prompted by initial observations that epilepsy patients receiving these treatments had positive mood effects. Nurses should be familiar with the concept of serendipity, as they often are in the best position to observe, record, and report on unexpected clinical effects in patients taking any kind of prescription or nonprescription medication.

    The evidence for a role of the striatum in the acquisition of uncued instrumental responding is ambiguous. It has been shown that post-session infusions of anisomycin into the core of the nucleus accumbens (NAcc) impaired instrumental acquisition, but pre-training lesions of the NAcc suggest that it is not necessary. Recently, we demonstrated that…

    2016-03-01

    Full Text Available APEX (Airborne Prism EXperiment is a high spectral and spatial resolution hyperspectral sensor developed by a Swiss-Belgian consortium on behalf of the European Space Agency. Since the acceptance of the instrument in 2010, it has been operated jointly by the Flemish Institute for Technological Research (VITO, Mol, Belgium and the Remote Sensing Laboratories (RSL, Zurich, Switzerland. During this period, several flight campaigns have been performed across Europe, gathering over 4 Terabytes of raw data. Following radiometric, geometric and atmospheric processing, this data has been provided to a multitude of Belgian and European researchers, institutes and agencies, including the European Space Agency (ESA, the European Facility for Airborne Research (EUFAR and the Belgian Science Policy Office (BelSPO. The applications of APEX data span a wide range of research topics, e.g. landcover mapping (mountainous, coastal, countryside and urban regions, the assessment of important structural and (biophysical characteristics of vegetative and non-vegetative species, the tracing of atmospheric gases, and water content analysis (chlorophyll, suspended matter. Recurrent instrument calibration, accurate flight planning and preparation, and experienced pilots and instrument operators are crucial to successful data acquisition campaigns. In this paper, we highlight in detail these practical aspects of a typical APEX data acquisition campaign.

  14. VERITAS Data Acquisition

    Science.gov (United States)

    Hays, E.

    VERITAS employs a multi-stage data acquisition chain that extends from the VME readout of custom 500 MHz flash ADC electronics to the construction of telescope events and ultimately the compilation of information from each telescope into array level data. These systems provide access to the programming of the channel level triggers and the FADCs. They also ensure the proper synchronization of event information across the array and provide the first level of data quality monitoring. Additionally, the data acquisition includes features to handle the readout of special trigger types and to monitor channel scaler rates. In this paper we describe the software and hardware components of the systems and the protocols used to communicate between the VME, telescope, and array levels. We also discuss the performance of the data acquisition for array operations.

    Watkins, Steve E.; Swift, Theresa M.; Fonda, James W.

    2008-03-01

    Triggering instrumentation for autonomous monitoring of load-induced strain is described for economical, fast bridge inspection. The development addresses one aspect for the management of transportation infrastructure - bridge monitoring and inspection. The objectives are to provide quantitative performance information from a load test, to minimize the setup time at the bridge, and to minimize the closure time to traffic. Multiple or networked measurements can be made for a prescribed loading sequence. The proposed smart system consists of in-situ strain sensors, an embedded data acquisition module, and a measurement triggering system. A companion control unit is mounted on the truck serving as the load. As the truck moves to the proper position, the desired measurement is automatically relayed back to the control unit. In this work, the testing protocol is developed and the performance parameters for the triggering and data acquisition are measured. The test system uses a dedicated wireless sensor mote and an infrared positioning system. The electronic procedure offers improvements in available information and economics.

    During the 1970s and 1980s, before synthesizers based on direct sampling of musical sounds became popular, replicating musical instruments using frequency modulation (FM) or wavetable synthesis was one of the “holy grails” of music synthesis. Synthesizers such as the Yamaha DX7 allowed users great flexibility in mixing and matching sounds, but were notoriously difficult to coerce into producing sounds like those of a given instrument. Instrument design wizards practiced the mysteries of FM instrument design.

    Full Text Available In this paper the experimental identification problem of thermal processes is presented, in order to establish their mathematical models which permit the adoption of the automation solutions, respectively the specification of a suitable control law. With this aim in view, the authors resorted to use Virtual Instrumentation with the aid of the LabVIEW development medium. In order to solve the problem of acquisition and processing data from physical real processes, Virtual Instruments which provide at the end a mathematical model which is basis of choosing the automation equipment of the aim followed was designed and achieved. The achieved Virtual Instruments get the opportunity to be used either in student instruction field with the virtual processes identification techniques or to put the identification of some real processes to good use of diverse beneficiaries. The results of some experimental attempts which were achieved during different thermal processes, illustrate the utility of the demarches performed in this paper.

    De Marcken, C

    1996-01-01

    This thesis presents a computational theory of unsupervised language acquisition, precisely defining procedures for learning language from ordinary spoken or written utterances, with no explicit help from a teacher. The theory is based heavily on concepts borrowed from machine learning and statistical estimation. In particular, learning takes place by fitting a stochastic, generative model of language to the evidence. Much of the thesis is devoted to explaining conditions that must hold for this general learning strategy to arrive at linguistically desirable grammars. The thesis introduces a variety of technical innovations, among them a common representation for evidence and grammars, and a learning strategy that separates the ``content'' of linguistic parameters from their representation. Algorithms based on it suffer from few of the search problems that have plagued other computational approaches to language acquisition. The theory has been tested on problems of learning vocabularies and grammars from unse...

  20. Amplitudes, acquisition and imaging

    Energy Technology Data Exchange (ETDEWEB)

    Bloor, Robert

    1998-12-31

    Accurate seismic amplitude information is important for the successful evaluation of many prospects and the importance of such amplitude information is increasing with the advent of time lapse seismic techniques. It is now widely accepted that the proper treatment of amplitudes requires seismic imaging in the form of either time or depth migration. A key factor in seismic imaging is the spatial sampling of the data and its relationship to the imaging algorithms. This presentation demonstrates that acquisition caused spatial sampling irregularity can affect the seismic imaging and perturb amplitudes. Equalization helps to balance the amplitudes, and the dealing strategy improves the imaging further when there are azimuth variations. Equalization and dealiasing can also help with the acquisition irregularities caused by shot and receiver dislocation or missing traces. 2 refs., 2 figs.

    The Visible Integral-Field Replicable Unit Spectrograph (VIRUS) instrument will be installed at the Hobby-Eberly Telescope† in the near future. The instrument will be housed in two enclosures that are mounted adjacent to the telescope, via the VIRUS Support Structure (VSS). We have designed the enclosures to support and protect the instrument, to enable servicing of the instrument, and to cool the instrument appropriately while not adversely affecting the dome environment. The system uses simple HVAC air handling techniques in conjunction with thermoelectric and standard glycol heat exchangers to provide efficient heat removal. The enclosures also provide power and data transfer to and from each VIRUS unit, liquid nitrogen cooling to the detectors, and environmental monitoring of the instrument and dome environments. In this paper, we describe the design and fabrication of the VIRUS enclosures and their subsystems.

    Second language acquisition (SLA) is a field that investigates child and adult SLA from a variety of theoretical perspectives. This article provides a survey of some key areas of concern including formal generative theory and emergentist theory in the areas of morpho-syntax and phonology. The review details the theoretical stance of the two different approaches to the nature of language: generative linguistics and general cognitive approaches. Some results of key acquisition studies from the two theoretical frameworks are discussed. From a generative perspective, constraints on wh-movement, feature geometry and syllable structure, and morphological development are highlighted. From a general cognitive point of view, the emergence of tense and aspect marking from a prototype account of inherent lexical aspect is reviewed. Reference is made to general cognitive learning theories and to sociocultural theory. The article also reviews individual differences research, specifically debate on the critical period in adult language acquisition, motivation, and memory. Finally, the article discusses the relationship between SLA research and second language pedagogy. Suggestions for further reading from recent handbooks on SLA are provided.

    2013-01-01

    Learning theory has frequently been applied to language acquisition, but discussion has largely focused on information theoretic problems-in particular on the absence of direct negative evidence. Such arguments typically neglect the probabilistic nature of cognition and learning in general. We argue first that these arguments, and analyses based on them, suffer from a major flaw: they systematically conflate the hypothesis class and the learnable concept class. As a result, they do not allow one to draw significant conclusions about the learner. Second, we claim that the real problem for language learning is the computational complexity of constructing a hypothesis from input data. Studying this problem allows for a more direct approach to the object of study--the language acquisition device-rather than the learnable class of languages, which is epiphenomenal and possibly hard to characterize. The learnability results informed by complexity studies are much more insightful. They strongly suggest that target grammars need to be objective, in the sense that the primitive elements of these grammars are based on objectively definable properties of the language itself. These considerations support the view that language acquisition proceeds primarily through data-driven learning of some form.

    Stewart, R. H.

    1981-01-01

    It is pointed out that no instrument is sensitive to only one oceanographic variable; rather, each responds to a combination of atmospheric and oceanic phenomena. This complicates data interpretation and usually requires that a number of observations, each sensitive to somewhat different phenomena, be combined to provide unambiguous information. The distinction between active and passive instruments is described. A block diagram illustrating the steps necessary to convert data from satellite instruments into oceanographic information is included, as is a diagram illustrating the operation of a radio-frequency radiometer. Attention is also given to the satellites that carry the various oceanographic instruments.

    Raju, Anju P.; Sekhar, Ambika

    2012-09-01

    This paper introduces a high speed distributed data acquisition system based on a field programmable gate array (FPGA). The aim is to develop a "distributed" data acquisition interface. The development of instruments such as personal computers and engineering workstations based on "standard" platforms is the motivation behind this effort. Using standard platforms as the controlling unit allows independence in hardware from a particular vendor and hardware platform. The distributed approach also has advantages from a functional point of view: acquisition resources become available to multiple instruments; the acquisition front-end can be physically remote from the rest of the instrument. High speed data acquisition system transmits data faster to a remote computer system through Ethernet interface. The data is acquired through 16 analog input channels. The input data commands are multiplexed and digitized and then the data is stored in 1K buffer for each input channel. The main control unit in this design is the 16 bit processor implemented in the FPGA. This 16 bit processor is used to set up and initialize the data source and the Ethernet controller, as well as control the flow of data from the memory element to the NIC. Using this processor we can initialize and control the different configuration registers in the Ethernet controller in a easy manner. Then these data packets are sending to the remote PC through the Ethernet interface. The main advantages of the using FPGA as standard platform are its flexibility, low power consumption, short design duration, fast time to market, programmability and high density. The main advantages of using Ethernet controller AX88796 over others are its non PCI interface, the presence of embedded SRAM where transmit and reception buffers are located and high-performance SRAM-like interface. The paper introduces the implementation of the distributed data acquisition using FPGA by VHDL. The main advantages of this system are high

    With the increasing complexity of today's systems, detailed performance analysis is more important than ever. We have developed DynTG, a tool for interactive, dynamic instrumentation. It uses performance module plugins to reconfigure the data acquisition and provides a source browser that allows users to insert any probe functionality provided by the modules dynamically into the target application. Any instrumentation can be added both before and during the application's execution and the acquired data is presented in realtime within the source viewer. This enables users to monitor their applications' progress and interactively control and adapt the instrumentation based on their observations.

    2014-06-01

    Full Text Available Under the development of favourable globalization conditions, the demand for and importance of knowledge in the insurance sector are rapidly growing, which is characterized by the variety of insurance services and offered products as well as by a permanent change in efforts to efficiently meet the needs of society. Therefore, knowledge is becoming a unique factor that leads to the increased exclusivity of the organization in this particular sector when the recently acquired knowledge helps the employees of the company with efficiently performing work activities and creating for consumer advantages that can be hardly imitated by other insurance organizations. However, the process of knowledge acquisition will be worthless without efficient instruments for assessing the procedures leading to obtaining the necessary knowledge on demand and time. Every insurance organization in Lithuania tries to acquire the necessary knowledge on time in the most convenient way; however, researchers and business representatives feel a lack of tools for assessing and improving the knowledge acquisition process. According to scientific literature, a lack of complexity evaluating the knowledge acquisition process creates a precondition for developing instruments for the assessment of this process. The object of research is the evaluation of the knowledge acquisition process in the organizations of Lithuanian insurance sector. The goal of the article is to offer an integrated instrument of the knowledge acquisition process for the organization working in Lithuanian insurance sector. To achieve this goal, the following tasks have been implemented: the analysis of the theoretical aspects of the factors and methods of the knowledge acquisition process; the establishment of the factors specific to organizations in Lithuanian insurance sector for the purposes of assessing the knowledge acquisition process; the identification of the problematic areas of the knowledge

    The diversity of upcoming experiments within the NUSTAR collaboration, including experiments in storage rings, reactions at relativistic energies and high-precision spectroscopy, is reflected in the diversity of the required detection systems. A challenging task is to incorporate the different needs of individual detectors within the unified NUSTAR Data AcQuisition (NDAQ). NDAQ takes up this challenge by providing a high degree of availability via continuously running systems, high flexibility via experiment-specific configuration files for data streams and trigger logic, distributed timestamps and trigger information on km distances, all built on the solid basis of the GSI Multi-Branch System. NDAQ ensures interoperability between individual NUSTAR detectors and allows merging of formerly separate data streams according to the needs of all experiments, increasing reliability in NUSTAR data acquisition. An overview of the NDAQ infrastructure and the current progress is presented.

    This article reviews current approaches to first language acquisition, arguing in favor of the theory that attributes to the child an innate knowledge of universal grammar. Such knowledge can accommodate the systematic nature of children's non-adult linguistic behaviors. The relationships between performance devices (mechanisms for comprehension and production of speech), non-linguistic aspects of cognition, and child grammars are also discussed.

    2012-03-01

    Flow cytometry is a complete technology given to biologists to study cellular populations with high precision. This technology elegantly combines sample dimension, data acquisition speed, precision and measurement multiplicity. Beyond the statistical aspect, flow cytometry offers the possibility to physically separate sub-populations. These performances come from the common endeavor of physicists, biophysicists, biologists and computer engineers, who succeeded, by providing new concepts, to bring flow cytometry to current maturity. The aim of this paper is to present a complete retrospective of the technique and remind flow cytometry fundamentals before focusing on recent commercial instrumentation.

    1993-12-31

    A miniaturized multichannel scaler instrument has been developed to address size and operational constraints for data acquisition in a portable laser-induced luminescence system. The multichannel scaling (MCS) function is implemented as a programmable application specific integrated circuit (ASIC) with standard interfaces for control and data acquisition. The instrument is microcontroller-based with sufficient computing power for data manipulation and algorithmic processing. The unit includes electronics for laser control, and amplification and pulse height discrimination of PMT pulses. Modification of the instrument should allow use in nuclear, chemical, and spectroscopy related applications including Mossbauer experiments. Interfaces are incorporated allowing both computer-controlled and stand alone operation. Implementation of the MCS function as an ASIC and comparison with conventional implementations are discussed. Full characterization of the MCS is presented including differential non-linearity (DNL), bin dead time, and bandwidth measurements.

  10. Treating the Synapse in Major Psychiatric Disorders: The Role of Postsynaptic Density Network in Dopamine-Glutamate Interplay and Psychopharmacologic Drugs Molecular Actions

    Directory of Open Access Journals (Sweden)

    Carmine Tomasetti

    2017-01-01

    Full Text Available Dopamine-glutamate interplay dysfunctions have been suggested as pathophysiological key determinants of major psychotic disorders, above all schizophrenia and mood disorders. For the most part, synaptic interactions between dopamine and glutamate signaling pathways take part in the postsynaptic density, a specialized ultrastructure localized under the membrane of glutamatergic excitatory synapses. Multiple proteins, with the role of adaptors, regulators, effectors, and scaffolds compose the postsynaptic density network. They form structural and functional crossroads where multiple signals, starting at membrane receptors, are received, elaborated, integrated, and routed to appropriate nuclear targets. Moreover, transductional pathways belonging to different receptors may be functionally interconnected through postsynaptic density molecules. Several studies have demonstrated that psychopharmacologic drugs may differentially affect the expression and function of postsynaptic genes and proteins, depending upon the peculiar receptor profile of each compound. Thus, through postsynaptic network modulation, these drugs may induce dopamine-glutamate synaptic remodeling, which is at the basis of their long-term physiologic effects. In this review, we will discuss the role of postsynaptic proteins in dopamine-glutamate signals integration, as well as the peculiar impact of different psychotropic drugs used in clinical practice on postsynaptic remodeling, thereby trying to point out the possible future molecular targets of “synapse-based” psychiatric therapeutic strategies.

  11. Unsupervised Language Acquisition

    de Marcken, Carl

    1996-11-01

    This thesis presents a computational theory of unsupervised language acquisition, precisely defining procedures for learning language from ordinary spoken or written utterances, with no explicit help from a teacher. The theory is based heavily on concepts borrowed from machine learning and statistical estimation. In particular, learning takes place by fitting a stochastic, generative model of language to the evidence. Much of the thesis is devoted to explaining conditions that must hold for this general learning strategy to arrive at linguistically desirable grammars. The thesis introduces a variety of technical innovations, among them a common representation for evidence and grammars, and a learning strategy that separates the ``content'' of linguistic parameters from their representation. Algorithms based on it suffer from few of the search problems that have plagued other computational approaches to language acquisition. The theory has been tested on problems of learning vocabularies and grammars from unsegmented text and continuous speech, and mappings between sound and representations of meaning. It performs extremely well on various objective criteria, acquiring knowledge that causes it to assign almost exactly the same structure to utterances as humans do. This work has application to data compression, language modeling, speech recognition, machine translation, information retrieval, and other tasks that rely on either structural or stochastic descriptions of language.

    1995-08-01

    Up to now, DAPHNE, the data-acquisition system developed for ATLAS, was used routinely for experiments at ATLAS and the Dynamitron. More recently, the Division implemented 2 MSU/DAPHNE systems. The MSU/DAPHNE system is a hybrid data-acquisition system which combines the front-end of the Michigan State University (MSU) DA system with the traditional DAPHNE back-end. The MSU front-end is based on commercially available modules. This alleviates the problems encountered with the DAPHNE front-end which is based on custom designed electronics. The first MSU system was obtained for the APEX experiment and was used there successfully. A second MSU front-end, purchased as a backup for the APEX experiment, was installed as a fully-independent second MSU/DAPHNE system with the procurement of a DEC 3000 Alpha host computer, and was used successfully for data-taking in an experiment at ATLAS. Additional hardware for a third system was bought and will be installed. With the availability of 2 MSU/DAPHNE systems in addition to the existing APEX setup, it is planned that the existing DAPHNE front-end will be decommissioned.

    2014-07-01

    Full Text Available To carry out this project an electronic multichannel system of electrochemical measurement or multipotenciostat was developed. It is based on the cyclic voltammetry measurement technique, controlled by a computer that monitors, by means of an electronic circuit, both the voltage generated from the Pc and supplied to an electrolytic cell, and the current that flows through the electrodes of it. To design the application software and the user interface, Virtual Instrumentation was used. On the other hand, to perform the communication between the multipotenciostat circuit and the designed software, the National Instruments NI9263 and NI9203 acquisition modules were used. The system was tested on a substance with a known REDOX property, as well as to discriminate and classify some samples of coffee.

    This essay proposes that our understanding of medical instruments might benefit from adding a more forthright concern with their immediate presence to the current historical focus on simply decoding their meanings and context. This approach is applied to the intriguingly tricky question of what...... actually is meant by a "medical instrument." It is suggested that a pragmatic part of the answer might lie simply in reconsidering the holdings of medical museums, where the significance of the physical actuality of instruments comes readily to hand....

    Developments in mass spectrometry instrumentation over the past three years are reviewed. The subject is characterized by an enormous diversity of designs, a high degree of competition between different laboratories working with either different or similar techniques and by extremely rapid progress in improving analytical performance. Instruments can be grouped into genealogical charts based on their physical and conceptual interrelationships. This is illustrated using mass analyzers of different types. The time course of development of particular instrumental concepts is illustrated in terms of the s-curves typical of cell growth. Examples are given of instruments which are at the exponential, linear and mature growth stages. The prime examples used are respectively: (i) hybrid instruments designed to study reactive collisions of ions with surfaces: (ii) the Paul ion trap; and (iii) the triple quadrupole mass spectrometer. In the area of ion/surface collisions, reactive collisions such as hydrogen radical abstraction from the surface by the impinging ion are studied. They are shown to depend upon the chemical nature of the surface through the use of experiments which utilize self-assembled monolayers as surfaces. The internal energy deposited during surface-induced dissociation upon collision with different surfaces in a BEEQ instrument is also discussed. Attention is also given to a second area of emerging instrumentation, namely technology which allows mass spectrometers to be used for on-line monitoring of fluid streams. A summary of recent improvements in the performance of the rapidly developing quadrupole ion trap instrument illustrates this stage of instrument development. Improvements in resolution and mass range and their application to the characterization of biomolecules are described. The interaction of theory with experiment is illustrated through the role of simulations of ion motion in the ion trap. It is emphasized that mature instruments play a

    In this paper we describe the main characteristics of the JEM-EUSO instrument. The Extreme Universe Space Observatory on the Japanese Experiment Module (JEM-EUSO) of the International Space Station (ISS) will observe Ultra High-Energy Cosmic Rays (UHECR) from space. It will detect UV-light of Extensive Air Showers (EAS) produced by UHECRs traversing the Earth's atmosphere. For each event, the detector will determine the energy, arrival direction and the type of the primary particle. The advantage of a space-borne detector resides in the large field of view, using a target volume of about 1012 tons of atmosphere, far greater than what is achievable from ground. Another advantage is a nearly uniform sampling of the whole celestial sphere. The corresponding increase in statistics will help to clarify the origin and sources of UHECRs and characterize the environment traversed during their production and propagation. JEM-EUSO is a 1.1 ton refractor telescope using an optics of 2.5 m diameter Fresnel lenses to focus the UV-light from EAS on a focal surface composed of about 5,000 multi-anode photomultipliers, for a total of ≃3ṡ105 channels. A multi-layer parallel architecture handles front-end acquisition, selecting and storing valid triggers. Each processing level filters the events with increasingly complex algorithms using FPGAs and DSPs to reject spurious events and reduce the data rate to a value compatible with downlink constraints.

    We describe telescopes and instruments that were developed and used for astronomical research in the ultraviolet (UV) and extreme ultraviolet (EUV) regions of the electromagnetic spectrum. The wavelength ranges covered by these bands are not uniquely defined. We use the following convention here: The EUV and UV span the regions ~100-912 and 912-3000 Angstroem respectively. The limitation between both ranges is a natural choice, because the hydrogen Lyman absorption edge is located at 912 Angstroem. At smaller wavelengths, astronomical sources are strongly absorbed by the interstellar medium. It also marks a technical limit, because telescopes and instruments are of different design. In the EUV range, the technology is strongly related to that utilized in X-ray astronomy, while in the UV range the instruments in many cases have their roots in optical astronomy. We will, therefore, describe the UV and EUV instruments in appropriate conciseness and refer to the respective chapters of this volume for more technic...

  10. Modeling of Musical Instruments

    Science.gov (United States)

    Bader, Rolf; Hansen, Uwe

    Signal processing techniques in acoustics address many concerns. Included are such things as wave propagation variables, amplitude considerations, spectral content, wavelength, and phase. Phase is primarily of concern when waves interact with each other, as well as with a medium, and the imposition of boundary conditions leads to normal mode vibrations. Such conditions are prevalent in all musical instruments, and thus relevant signal processing techniques are essential to both understanding and modeling the structure of musical instruments and the sound radiated.

  11. Data acquisition time constraints in elevation mapping corneal topography

    Science.gov (United States)

    Baron, William S.; Baron, Sandra F.

    1997-05-01

    Elevation mapping corneal topography instruments provide an array of x, y, z data points describing the corneal surface. An advantage of elevation mapping instruments is their ability to calculate the 3D data array strictly from the instrument's geometry and calibration data; no assumptions about the corneal surface itself are needed. However, uncompensated eye movements can affect accuracy. Longitudinal eye movements occur along the z axis, due to pulmonary and cardiac pulsations. Eye rotations due to saccades and drifts are normal occurrences, as are translational body movements. An analysis of eye and body movements at the cornea's surface indicates a nearly linear relationship between data acquisition times of less than 33 msec, and the possible change in elevation at a point referenced to an instrument axis. The proportionality constant is expected to vary by a factor of about six over the range of clinical patients, since eye and body movements are exaggerated in juvenile patients, geriatric patients, and patients with poor vision. The analysis estimates an elevation change due to rotation and longitudinal translation of the eye of up to +/- 285 micrometers in 33 msec within the clinical population. This analysis indicates that when a topographer's acquisition time is greater than 100 microsecond(s) ec (during which an apparent elevation change of up to 1.0 micrometers may occur) testing on static objects may not provide a realistic measure of an instrument's clinical performance.

    A prototype of digital frequency multiplexing electronics allowing the real time monitoring of microwave kinetic inductance detector (MKIDs) arrays for mm-wave astronomy has been developed. It requires only 2 coaxial cables for instrumenting a large array. For that, an excitation comb of frequencies is generated and fed through the detector. The direct frequency synthesis and the data acquisition relies heavily on a large FPGA using parallelized and pipelined processing. The prototype can instrument 128 resonators (pixels) over a bandwidth of 125 MHz. This paper describes the technical solution chosen, the algorithm used and the results obtained.

    Existing planet-finding spectrometers are limited by systematic errors that result from their seeing-limited design. Of particular concern is the use of multi-mode fibers (MMFs), which introduce modal noise and accept significant amounts of background radiation from the sky. We present the design of a single-mode fiber-based acquisition camera for a diffraction-limited spectrometer named "iLocater." By using the "extreme" adaptive optics (AO) system of the Large Binocular Telescope (LBT), iLocater will overcome the limitations that prevent Doppler instruments from reaching their full potential, allowing precise radial velocity (RV) measurements of terrestrial planets around nearby bright stars. The instrument presented in this paper, which we refer to as the acquisition camera "demonstration system," will measure on-sky single-mode fiber (SMF) coupling efficiency using one of the 8.4m primaries of the LBT in fall 2015.

  14. Language Acquisition in Computers

    This project explores the nature of language acquisition in computers, guided by techniques similar to those used in children. While existing natural language processing methods are limited in scope and understanding, our system aims to gain an understanding of language from first principles and hence minimal initial input. The first portion of our system was implemented in Java and is focused on understanding the morphology of language using bigrams. We use frequency distributions and differences between them to define and distinguish languages. English and French texts were analyzed to determine a difference threshold of 55 before the texts are considered to be in different languages, and this threshold was verified using Spanish texts. The second portion of our system focuses on gaining an understanding of the syntax of a language using a recursive method. The program uses one of two possible methods to analyze given sentences based on either sentence patterns or surrounding words. Both methods have been i...

  15. Living musical instruments and inanimate body parts?

    Barbarotto, R; Capitani, E; Laiacona, M

    2001-01-01

    In the literature about category effects in semantic memory, body parts and musical instruments are often considered atypical, because in cases with a disproportionate impairment of living categories body parts are relatively spared, while musical instruments are often severely defective. In this study the performance of 57 subjects affected by diseases generally associated with lexical-semantic impairment, for the most part Alzheimer's disease and other forms of cortical degeneration, but also herpetic encephalitis and traumatic brain damage are analyzed. The subjects were given a picture naming task tapping eight categories: three living categories (animals, fruits and vegetables) and three non-living categories (tools, furniture and vehicles), plus body parts and musical instruments. On a preliminary analysis at the group level, body parts were the least impaired category and musical instruments the most severely impaired, the six living and non-living categories being intermediate. However, these differences disappeared after covariance for lexical frequency, name agreement and age of acquisition. The relationship between living categories, non-living categories, musical instruments and body parts was investigated by means of a Lisrel model of Confirmatory Factor Analysis. Two latent variables related to living and non-living categories respectively were defined, and it was found that both body parts and musical instruments were significantly related only with non-living categories. The results showed that the definition of the latent variable expressing the substrate of non-living categories was less satisfactory than that expressing the living categories. On this basis, the conclusions of this study appear statistically definite but their psychological interpretation is less straightforward.

  17. Theories of language acquisition.

    Science.gov (United States)

    Vetter, H J; Howell, R W

    1971-03-01

    Prior to the advent of generative grammar, theoretical approaches to language development relied heavily upon the concepts ofdifferential reinforcement andimitation. Current studies of linguistic acquisition are largely dominated by the hypothesis that the child constructs his language on the basis of a primitive grammar which gradually evolves into a more complex grammar. This approach presupposes that the investigator does not impose his own grammatical rules on the utterances of the child; that the sound system of the child and the rules he employs to form sentences are to be described in their own terms, independently of the model provided by the adult linguistic community; and that there is a series of steps or stages through which the child passes on his way toward mastery of the adult grammar in his linguistic environment. This paper attempts to trace the development of human vocalization through prelinguistic stages to the development of what can be clearly recognized as language behavior, and then progresses to transitional phases in which the language of the child begins to approximate that of the adult model. In the view of the authors, the most challenging problems which confront theories of linguistic acquisition arise in seeking to account for structure of sound sequences, in the rules that enable the speaker to go from meaning to sound and which enable the listener to go from sound to meaning. The principal area of concern for the investigator, according to the authors, is the discovery of those rules at various stages of the learning process. The paper concludes with a return to the question of what constitutes an adequate theory of language ontogenesis. It is suggested that such a theory will have to be keyed to theories of cognitive development and will have to include and go beyond a theory which accounts for adult language competence and performance, since these represent only the terminal stage of linguistic ontogenesis.

  18. Reducing the Cost of Laparoscopy: Reusable versus Disposable Laparoscopic Instruments

    2014-01-01

    Full Text Available Cost-effectiveness in health care management is critical. The situation in debt-stricken Greece is further aggravated by the financial crisis and constant National Health System expense cut-downs. In an effort to minimize the cost of laparoscopy, our department introduced reusable laparoscopic instruments in December 2011. The aim of this study was to assess potential cost reduction of laparoscopic operations in the field of general surgery. Hospital records, invoice lists, and operative notes between January 2012 and December 2013, were retrospectively reviewed and data were collected on laparoscopic procedures, instrument failures, and replacement needs. Initial acquisition cost of 5 basic instrument sets was €21,422. Over the following 24 months, they were used in 623 operations, with a total maintenance cost of €11,487. Based on an average retail price of €490 per set, projected cost with disposable instruments would amount to €305,270, creating savings of €272,361 over the two-year period under study. Despite the seemingly high purchase price, each set amortized its acquisition cost after only 9 procedures and instrument cost depreciated to less than €55 per case. Disposable instruments cost 9 times more than reusable ones, and their high price would almost equal the total hospital reimbursement by social security funds for many common laparoscopic procedures.

    2002-01-01

    Several attempts have been made recently to apply techniques such as model checking and theorem proving to the analysis of programs. This shall be seen as a current trend to analyze real software systems instead of just their designs. This includes our own effort to develop a model checker for Java, the Java PathFinder 1, one of the very first of its kind in 1998. However, model checking cannot handle very large programs without some kind of abstraction of the program. This paper describes a complementary scalable technique to handle such large programs. Our interest is turned on the observation part of the equation: How much information can be extracted about a program from observing a single execution trace? It is our intention to develop a technology that can be applied automatically and to large full-size applications, with minimal modification to the code. We present a tool, Java PathExplorer (JPaX), for exploring execution traces of Java programs. The tool prioritizes scalability for completeness, and is directed towards detecting errors in programs, not to prove correctness. One core element in JPaX is an instrumentation package that allows to instrument Java byte code files to log various events when executed. The instrumentation is driven by a user provided script that specifies what information to log. Examples of instructions that such a script can contain are: 'report name and arguments of all called methods defined in class C, together with a timestamp'; 'report all updates to all variables'; and 'report all acquisitions and releases of locks'. In more complex instructions one can specify that certain expressions should be evaluated and even that certain code should be executed under various conditions. The instrumentation package can hence be seen as implementing Aspect Oriented Programming for Java in the sense that one can add functionality to a Java program without explicitly changing the code of the original program, but one rather writes an

    Science.gov (United States)

    Azzolini, John D.; McGlew, David E.

    1990-12-01

    The Two Axis Pointing System (TAPS) is a 2 axis gimbal system designed to provide fine pointing of Space Transportation System (STS) borne instruments. It features center-of-mass instrument mounting and will accommodate instruments of up to 1134 kg (2500 pounds) which fit within a 1.0 by 1.0 by 4.2 meter (40 by 40 by 166 inch) envelope. The TAPS system is controlled by a microcomputer based Control Electronics Assembly (CEA), a Power Distribution Unit (PDU), and a Servo Control Unit (SCU). A DRIRU-II inertial reference unit is used to provide incremental angles for attitude propagation. A Ball Brothers STRAP star tracker is used for attitude acquisition and update. The theory of the TAPS attitude determination and error computation for the Broad Band X-ray Telescope (BBXRT) are described. The attitude acquisition is based upon a 2 star geometric solution. The acquisition theory and quaternion algebra are presented. The attitude control combines classical position, integral and derivative (PID) control with techniques to compensate for coulomb friction (bias torque) and the cable harness crossing the gimbals (spring torque). Also presented is a technique for an adaptive bias torque compensation which adjusts to an ever changing frictional torque environment. The control stability margins are detailed, with the predicted pointing performance, based upon simulation studies. The TAPS user interface, which provides high level operations commands to facilitate science observations, is outlined.

  9. FPGA Flash Memory High Speed Data Acquisition

    Gonzalez, April

    2013-01-01

    The purpose of this research is to design and implement a VHDL ONFI Controller module for a Modular Instrumentation System. The goal of the Modular Instrumentation System will be to have a low power device that will store data and send the data at a low speed to a processor. The benefit of such a system will give an advantage over other purchased binary IP due to the capability of allowing NASA to re-use and modify the memory controller module. To accomplish the performance criteria of a low power system, an in house auxiliary board (Flash/ADC board), FPGA development kit, debug board, and modular instrumentation board will be jointly used for the data acquisition. The Flash/ADC board contains four, 1 MSPS, input channel signals and an Open NAND Flash memory module with an analog to digital converter. The ADC, data bits, and control line signals from the board are sent to an Microsemi/Actel FPGA development kit for VHDL programming of the flash memory WRITE, READ, READ STATUS, ERASE, and RESET operation waveforms using Libero software. The debug board will be used for verification of the analog input signal and be able to communicate via serial interface with the module instrumentation. The scope of the new controller module was to find and develop an ONFI controller with the debug board layout designed and completed for manufacture. Successful flash memory operation waveform test routines were completed, simulated, and tested to work on the FPGA board. Through connection of the Flash/ADC board with the FPGA, it was found that the device specifications were not being meet with Vdd reaching half of its voltage. Further testing showed that it was the manufactured Flash/ADC board that contained a misalignment with the ONFI memory module traces. The errors proved to be too great to fix in the time limit set for the project.

    Manchester, Ralph A

    2014-06-01

    Now that the field of performing arts medicine has been in existence for over three decades, we are approaching a key point: we should start to see more articles that bring together the data that have been collected from several studies in order to draw more robust conclusions. Review articles and their more structured relative, the meta-analysis, can help to improve our understanding of a particular topic, comparing and synthesizing the results of previous research that has been done on that subject area. One way this could be done would be to review the research that has been carried out on the performance-related problems associated with playing a particular instrument or group of instruments. While I am not going to do that myself, I hope that others will. In this editorial, I will do a very selective review of the playing-related musculoskeletal disorders (PRMDs) associated with one instrument group (the keyboard instruments), focusing on the most played instrument in that group (the piano;).

  18. Options for Next Generation Digital Acquisition Systems

    CERN Document Server

    Boccardi, A

    2011-01-01

    Digital acquisition system designers have an always increasing number of options in terms of bus standards and digital signal processing hardware among which to choose. This allows for high flexibility but also opens the door to a proliferation of different architectures, potentially limiting the reusability and the design synergies among the various instrumentation groups. This contribution illustrates the design trends in some of the major institutes around the world with design examples including VME, PCI and TCA based modular systems using AMC and/or FMC mezzanines. Some examples of FPGA design practices aimed at increasing reusability of code will be mentioned together with some of the tools already available to designers to improve the information exchange and collaboration, like the Open Hardware Repository project.

    Energy Technology Data Exchange (ETDEWEB)

    Sedlacek, Arthur J [Brookhaven National Lab. (BNL), Upton, NY (United States)

    2016-04-01

    The Aethalometer is an instrument that provides a real-time readout of the concentration of “Black” or “Elemental” carbon aerosol particles (BC or E) in an air stream (see Figure 1 and Figure 2). It is a self-contained instrument that measures the rate of change of optical transmission through a spot on a filter where aerosol is being continuously collected and uses the information to calculate the concentration of optically absorbing material in the sampled air stream. The instrument measures the transmitted light intensities through the “sensing” portion of the filter, on which the aerosol spot is being collected, and a “reference” portion of the filter as a check on the stability of the optical source. A mass flowmeter monitors the sample air flow rate. The data from these three measurements is used to determine the mean BC content of the air stream.

    Bershady, Matthew A

    2009-01-01

    In this Chapter we review the challenges of, and opportunities for, 3D spectroscopy, and how these have lead to new and different approaches to sampling astronomical information. We describe and categorize existing instruments on 4m and 10m telescopes. Our primary focus is on grating-dispersed spectrographs. We discuss how to optimize dispersive elements, such as VPH gratings, to achieve adequate spectral resolution, high throughput, and efficient data packing to maximize spatial sampling for 3D spectroscopy. We review and compare the various coupling methods that make these spectrographs ``3D,'' including fibers, lenslets, slicers, and filtered multi-slits. We also describe Fabry-Perot and spatial-heterodyne interferometers, pointing out their advantages as field-widened systems relative to conventional, grating-dispersed spectrographs. We explore the parameter space all these instruments sample, highlighting regimes open for exploitation. Present instruments provide a foil for future development. We give an...

    Davidson, W. F.

    1986-01-01

    An electronics circuit which provides for the recording of instrumentation data on an optical disk is disclosed. The optical disk is formatted in a spiral format instead of concentric tracks. The spiral format allows data to be recorded without the gaps that would be associated with concentric tracks. The instrumentation system provides each channel with a program instrumentation amplifier, a six pole lowpass switched capacitor filter, a sample and hold amplifier, and a digital to analog converter to provide automatic offset capability. Since each channel has its own components, simultaneous samples of every channel can be captured. All of the input signal's channel variables can be captured. All of the input signal's channel variables can be changed under software control without hardware changes. A single board computer is used for a system controller.

    Full Text Available The rules laid down by Romanian Capital Market Law and the regulations put in force for its implementation apply to issuers of financial instruments admitted to trading on the regulated market established in Romania. But the issuers remain companies incorporated under Company Law of 1990. Such dual regulations need increased attention in order to observe the legal status of the issuers/companies and financial instruments/shares. Romanian legislator has chosen to implement in Capital Market Law special rules regarding the administration of the issuers of financial instruments, not only rules regarding admitting and maintaining to a regulated market. Thus issuers are, in Romanian Law perspective, special company that should comply special rule regarding board of administration and general shareholders meeting.

    2011-01-01

    Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five elements: (1) a common sensor interface, (2) microprocessor, (3) wireless interface, (4) signal conditioning and ADC/DAC (analog-to-digital conversion/ digital-to-analog conversion), and (5) onboard EEPROM (electrically erasable programmable read-only memory) for metadata storage and executable software to create powerful, scalable, reconfigurable, and reliable embedded and distributed test instruments. In order to maximize the efficient data conversion through the smart sensor node, plug-and-play functionality is required to interface with traditional sensors to enhance their identity and capabilities for data processing and communications. Virtual sensor test instrumentation can be accessible wirelessly via a Network Capable Application Processor (NCAP) or a Smart Transducer Interlace Module (STIM) that may be managed under real-time rule engines for mission-critical applications. The transducer senses the physical quantity being measured and converts it into an electrical signal. The signal is fed to an A/D converter, and is ready for use by the processor to execute functional transformation based on the sensor characteristics stored in a Transducer Electronic Data Sheet (TEDS). Virtual sensor test instrumentation is built upon an open-system architecture with standardized protocol modules/stacks to interface with industry standards and commonly used software. One major benefit for deploying the virtual sensor test instrumentation is the ability, through a plug-and-play common interface, to convert raw sensor data in either analog or digital form, to an IEEE 1451 standard-based smart sensor, which has instructions to program sensors for a wide variety of

  18. Instrumentation for the Characterization of Inflatable Structures

    Science.gov (United States)

    Swanson, Gregory T.; Cassell, Alan M.; Johnson, R. Keith

    2012-01-01

    Current entry, descent, and landing technologies are not practical for heavy payloads due to mass and volume constraints dictated by limitations imposed by launch vehicle fairings. Therefore, new technologies are now being explored to provide a mass- and volume-efficient solution for heavy payload capabilities, including Inflatable Aerodynamic Decelerators (IAD) [1]. Consideration of IADs for space applications has prompted the development of instrumentation systems for integration with flexible structures to characterize system response to flight-like environment testing. This development opportunity faces many challenges specific to inflatable structures in extreme environments, including but not limited to physical flexibility, packaging, temperature, structural integration and data acquisition [2]. In the spring of 2012, two large scale Hypersonic Inflatable Aerodynamic Decelerators (HIAD) will be tested in the National Full-Scale Aerodynamics Complex s 40 by 80 wind tunnel at NASA Ames Research Center. The test series will characterize the performance of a 3.0 m and 6.0 m HIAD at various angles of attack and levels of inflation during flight-like loading. To analyze the performance of these inflatable test articles as they undergo aerodynamic loading, many instrumentation systems have been researched and developed. These systems will utilize new experimental sensing systems developed by the HIAD ground test campaign instrumentation team, in addition to traditional wind tunnel sensing techniques in an effort to improve test article characterization and model validation. During the 2012 test series the instrumentation systems will target inflatable aeroshell static and dynamic deformation, structural strap loading, surface pressure distribution, localized skin deflection, and torus inflation pressure. This paper will offer an overview of inflatable structure instrumentation, and provide detail into the design and implementation of the sensors systems that will

    The Instrumentation Technical Program Management Team (ITPMT) was chartered to consolidate, coordinate, and manage Process and Long- Range Technical Support (P and LRTS) activities in the areas of process, environmental, health, and safety instrumentation. During FY-1988, steps have been taken toward improving the effectiveness of a limited technical support program, including initiation of the acquisition of a modest number of additional people, limitation of numbers of projects to a very selected few, and the encouragement of other Teams to address instrumentation development. This report will be in the same format as the last two. A generalized summation of instrumentation P and LRTS support known to be currently of high priority and expected to be addressed during the FY-1989 and FY-1991 time frame will be presented, with the expectation that addressing all of the listed work will be precluded by presently-unidentifiable demands. FY-1989 milestones will, however, be described in some detail.

    In the October 1994 round of proposals at the ILL, the external biology review sub- committee was asked to allocate neutron beam time to a wide range of experiments, on almost half the total number of scheduled neutron instruments: on 3 diffractometers, on 3 small angle scattering instruments, and on some 6 inelastic scattering spectrometers. In the 3.5 years since the temporary reactor shutdown, the ILL`s management structure has been optimized, budgets and staff have been trimmed, the ILL reactor has been re-built, and many of the instruments up-graded, many powerful (mainly Unix) workstations have been introduced, and the neighboring European Synchrotron Radiation Facility has established itself as the leading synchrotron radiation source and has started its official user program. The ILL reactor remains the world`s most intense dedicated neutron source. In this challenging context, it is of interest to review briefly the park of ILL instruments used to study the structure and energetics of small and large biological systems. A brief summary will be made of each class of experiments actually proposed in the latest ILL proposal round.

    Uin, J. [Brookhaven National Lab. (BNL), Upton, NY (United States)

    2016-03-01

    The Integrating Nephelometer (Figure 1) is an instrument that measures aerosol light scattering. It measures aerosol optical scattering properties by detecting (with a wide angular integration – from 7 to 170°) the light scattered by the aerosol and subtracting the light scattered by the carrier gas, the instrument walls and the background noise in the detector (zeroing). Zeroing is typically performed for 5 minutes every day at midnight UTC. The scattered light is split into red (700 nm), green (550 nm), and blue (450 nm) wavelengths and captured by three photomultiplier tubes. The instrument can measure total scatter as well as backscatter only (from 90 to 170°) (Heintzenberg and Charlson 1996; Anderson et al. 1996; Anderson and Ogren 1998; TSI 3563 2015) At ARM (Atmospheric Radiation Measurement), two identical Nephelometers are usually run in series with a sample relative humidity (RH) conditioner between them. This is possible because Nephelometer sampling is non-destructive and the sample can be passed on to another instrument. The sample RH conditioner scans through multiple RH values in cycles, treating the sample. This kind of setup allows to study how aerosol particles’ light scattering properties are affected by humidification (Anderson et al. 1996). For historical reasons, the two Nephelometers in this setup are labeled “wet” and “dry”, with the “dry” Nephelometer usually being the one before the conditioner and sampling ambient air (the names are switched for the MAOS measurement site due to the high RH of the ambient air).

    The semantic bootstrapping hypothesis proposes that children acquire their native language through exposure to sentences of the language paired with structured representations of their meaning, whose component substructures can be associated with words and syntactic structures used to express these concepts. The child's task is then to learn a language-specific grammar and lexicon based on (probably contextually ambiguous, possibly somewhat noisy) pairs of sentences and their meaning representations (logical forms). Starting from these assumptions, we develop a Bayesian probabilistic account of semantically bootstrapped first-language acquisition in the child, based on techniques from computational parsing and interpretation of unrestricted text. Our learner jointly models (a) word learning: the mapping between components of the given sentential meaning and lexical words (or phrases) of the language, and (b) syntax learning: the projection of lexical elements onto sentences by universal construction-free syntactic rules. Using an incremental learning algorithm, we apply the model to a dataset of real syntactically complex child-directed utterances and (pseudo) logical forms, the latter including contextually plausible but irrelevant distractors. Taking the Eve section of the CHILDES corpus as input, the model simulates several well-documented phenomena from the developmental literature. In particular, the model exhibits syntactic bootstrapping effects (in which previously learned constructions facilitate the learning of novel words), sudden jumps in learning without explicit parameter setting, acceleration of word-learning (the "vocabulary spurt"), an initial bias favoring the learning of nouns over verbs, and one-shot learning of words and their meanings. The learner thus demonstrates how statistical learning over structured representations can provide a unified account for these seemingly disparate phenomena. Copyright © 2017 Elsevier B.V.

  1. Autonomous Surface Sample Acquisition for Planetary and Lunar Exploration

    Science.gov (United States)

    Barnes, D. P.

    2007-08-01

    Surface science sample acquisition is a critical activity within any planetary and lunar exploration mission, and our research is focused upon the design, implementation, experimentation and demonstration of an onboard autonomous surface sample acquisition capability for a rover equipped with a robotic arm upon which are mounted appropriate science instruments. Images captured by a rover stereo camera system can be processed using shape from stereo methods and a digital elevation model (DEM) generated. We have developed a terrain feature identification algorithm that can determine autonomously from DEM data suitable regions for instrument placement and/or surface sample acquisition. Once identified, surface normal data can be generated autonomously which are then used to calculate an arm trajectory for instrument placement and sample acquisition. Once an instrument placement and sample acquisition trajectory has been calculated, a collision detection algorithm is required to ensure the safe operation of the arm during sample acquisition.We have developed a novel adaptive 'bounding spheres' approach to this problem. Once potential science targets have been identified, and these are within the reach of the arm and will not cause any undesired collision, then the 'cost' of executing the sample acquisition activity is required. Such information which includes power expenditure and duration can be used to select the 'best' target from a set of potential targets. We have developed a science sample acquisition resource requirements calculation that utilises differential inverse kinematics methods to yield a high fidelity result, thus improving upon simple 1st order approximations. To test our algorithms a new Planetary Analogue Terrain (PAT) Laboratory has been created that has a terrain region composed of Mars Soil Simulant-D from DLR Germany, and rocks that have been fully characterised in the laboratory. These have been donated by the UK Planetary Analogue Field Study

    The Stratospheric Aerosol and Gas Experiment 2 (SAGE 2) is discussed. The SAGE 2 instrument was a multichannel spectrometer that inferred the vertical distribution of water vapor, aerosols, nitrogen dioxide, and ozone by measuring the extinction of solar radiation at spacecraft sunrise/sunset. At altitudes above 20 km, the SAGE 2 and LIMS (Limb Infrared Monitor of the Stratosphere) data are in close agreement. The discrepancies below this altitude may be attributed to differences in the instruments' field of view and time of data acquisition.

    The CHaracterising ExOPlanet Satellite (CHEOPS) is the first ESA S-class and exoplanetary follow-up mission headed for launch in 2018. It will perform ultra-high-precision photometry of stars hosting confirmed exoplanets on a 3-axis stabilised sun-synchronous orbit that is optimised for uninterrupted observations at minimum stray light and thermal variations. Nevertheless, due to the satellites structural design, the alignment of the star trackers and the payload instrument telescope is affected by thermo-elastic deformations. This causes a high pointing uncertainty, which requires the payload instrument to provide an additional acquisition system for distinct target identification. Therefor a star extraction software and two star identification algorithms, originally designed for star trackers, were adapted and optimised for the special case of CHEOPS. In order to evaluate these algorithms reliability, thousands of random star configurations were analysed in Monte-Carlo simulations. We present the implemented identification methods and their performance as well as recommended parameters that guarantee a successful identification under all conditions.

    Pedemis (PortablE Decoupled Electromagnetic Induction Sensor) is a time-domain man-portable electromagnetic induction (EMI) instrument with the intended purpose of improving the detection and classification of UneXploded Ordnance (UXO). Pedemis sports nine coplanar transmitters (the Tx assembly) and nine triaxial receivers held in a fixed geometry with respect to each other (the Rx assembly) but with that Rx assembly physically decoupled from the Tx assembly allowing flexible data acquisition modes and deployment options. Such flexibility is expected to be instrumental in non-trivial terrains exhibiting either an abundant vegetation or being highly contaminated by large or dense clutter. Before validating the sensor in such challenging configurations, however, Pedemis was taken to Aberdeen Proving Ground, MD, for its first test site validation. We describe Pedemis, including its operation and data acquisition modes along with our Aberdeen Proving Ground results.

  7. Stress modulates instrumental learning performances in horses (Equus caballus in interaction with temperament.

    Directory of Open Access Journals (Sweden)

    Mathilde Valenchon

    Full Text Available The present study investigates how the temperament of the animal affects the influence of acute stress on the acquisition and reacquisition processes of a learning task. After temperament was assessed, horses were subjected to a stressor before or after the acquisition session of an instrumental task. Eight days later, horses were subjected to a reacquisition session without any stressor. Stress before acquisition tended to enhance the number of successes at the beginning of the acquisition session. Eight days later, during the reacquisition session, contrary to non-stressed animals, horses stressed after acquisition, and, to a lesser extent, horses stressed before acquisition, did not improve their performance between acquisition and reacquisition sessions. Temperament influenced learning performances in stressed horses only. Particularly, locomotor activity improved performances whereas fearfulness impaired them under stressful conditions. Results suggest that direct exposure to a stressor tended to increase acquisition performances, whereas a state of stress induced by the memory of a stressor, because it has been previously associated with the learning context, impaired reacquisition performances. The negative effect of a state of stress on reacquisition performances appeared to be stronger when exposure to the stressor occurred after rather than before the acquisition session. Temperament had an impact on both acquisition and reacquisition processes, but under stressful conditions only. These results suggest that stress is necessary to reveal the influence of temperament on cognitive performances.

    A flexible firmware architecture for different kinds of data acquisition systems, ranging from high-precision bench instruments to low-cost wireless transducers networks, is presented. The key component is a multi-behaviors finite state machine, easily configurable to both low- and high-performance requirements, to diverse operating systems, as well as to on-line and batch measurement algorithms. The proposed solution was validated experimentally on three case studies with data acquisition architectures: (i) concentrated, in a high-precision instrument for magnetic measurements at CERN, (ii) decentralized, for telemedicine remote monitoring of patients at home, and (iii) distributed, for remote monitoring of building's energy loss.

    Language acquisition involves brain processes that can be affected by lesions or dysfunctions in several brain systems and second language acquisition may depend on different brain substrates than first language acquisition in childhood. A total of 16 Russian immigrants to Israel, 8 diagnosed schizophrenics and 8 healthy immigrants, were compared. The primary data for this study were collected via sociolinguistic interviews. The two groups use language and learn language in very much the same way. Only exophoric reference and blocking revealed meaningful differences between the schizophrenics and healthy counterparts. This does not mean of course that schizophrenia does not induce language abnormalities. Our study focuses on those aspects of language that are typically difficult to acquire in second language acquisition. Despite the cognitive compromises in schizophrenia and the manifest atypicalities in language of speakers with schizophrenia, the process of acquiring a second language seems relatively unaffected by schizophrenia.

    Netherlands Hydrological Modeling Instrument A decision support system for water basin management. J.C. Hoogewoud , W.J. de Lange ,A. Veldhuizen , G. Prinsen , The Netherlands Hydrological modeling Instrument (NHI) is the center point of a framework of models, to coherently model the hydrological system and the multitude of functions it supports. Dutch hydrological institutes Deltares, Alterra, Netherlands Environmental Assessment Agency, RWS Waterdienst, STOWA and Vewin are cooperating in enhancing the NHI for adequate decision support. The instrument is used by three different ministries involved in national water policy matters, for instance the WFD, drought management, manure policy and climate change issues. The basis of the modeling instrument is a state-of-the-art on-line coupling of the groundwater system (MODFLOW), the unsaturated zone (metaSWAP) and the surface water system (MOZART-DM). It brings together hydro(geo)logical processes from the column to the basin scale, ranging from 250x250m plots to the river Rhine and includes salt water flow. The NHI is validated with an eight year run (1998-2006) with dry and wet periods. For this run different parts of the hydrology have been compared with measurements. For instance, water demands in dry periods (e.g. for irrigation), discharges at outlets, groundwater levels and evaporation. A validation alone is not enough to get support from stakeholders. Involvement from stakeholders in the modeling process is needed. There fore to gain sufficient support and trust in the instrument on different (policy) levels a couple of actions have been taken: 1. a transparent evaluation of modeling-results has been set up 2. an extensive program is running to cooperate with regional waterboards and suppliers of drinking water in improving the NHI 3. sharing (hydrological) data via newly setup Modeling Database for local and national models 4.

  1. Developments in analytical instrumentation

    Petrie, G.

    The situation regarding photogrammetric instrumentation has changed quite dramatically over the last 2 or 3 years with the withdrawal of most analogue stereo-plotting machines from the market place and their replacement by analytically based instrumentation. While there have been few new developments in the field of comparators, there has been an explosive development in the area of small, relatively inexpensive analytical stereo-plotters based on the use of microcomputers. In particular, a number of new instruments have been introduced by manufacturers who mostly have not been associated previously with photogrammetry. Several innovative concepts have been introduced in these small but capable instruments, many of which are aimed at specialised applications, e.g. in close-range photogrammetry (using small-format cameras); for thematic mapping (by organisations engaged in environmental monitoring or resources exploitation); for map revision, etc. Another innovative and possibly significant development has been the production of conversion kits to convert suitable analogue stereo-plotting machines such as the Topocart, PG-2 and B-8 into fully fledged analytical plotters. The larger and more sophisticated analytical stereo-plotters are mostly being produced by the traditional mainstream photogrammetric systems suppliers with several new instruments and developments being introduced at the top end of the market. These include the use of enlarged photo stages to handle images up to 25 × 50 cm format; the complete integration of graphics workstations into the analytical plotter design; the introduction of graphics superimposition and stereo-superimposition; the addition of correlators for the automatic measurement of height, etc. The software associated with this new analytical instrumentation is now undergoing extensive re-development with the need to supply photogrammetric data as input to the more sophisticated G.I.S. systems now being installed by clients, instead

    2011-06-01

    We describe the design of an instrument that can fully implement a new nanopatterning method called ice lithography, where ice is used as the resist. Water vapor is introduced into a scanning electron microscope (SEM) vacuum chamber above a sample cooled down to 110 K. The vapor condenses, covering the sample with an amorphous layer of ice. To form a lift-off mask, ice is removed by the SEM electron beam (e-beam) guided by an e-beam lithography system. Without breaking vacuum, the sample with the ice mask is then transferred into a metal deposition chamber where metals are deposited by sputtering. The cold sample is then unloaded from the vacuum system and immersed in isopropanol at room temperature. As the ice melts, metal deposited on the ice disperses while the metals deposited on the sample where the ice had been removed by the e-beam remains. The instrument combines a high beam-current thermal field emission SEM fitted with an e-beam lithography system, cryogenic systems, and a high vacuum metal deposition system in a design that optimizes ice lithography for high throughput nanodevice fabrication. The nanoscale capability of the instrument is demonstrated with the fabrication of nanoscale metal lines.

    One of the tasks specified in the NASA Langley controlled impact demonstration (CID) work package was to furnish dynamic instrumentation sensors. The types of instrumentation sensors required were accelerometers for aircraft structural loads measurements, seat belt load cells to measure anthropomorphic dummy responses to the aircraft impact, and strain gage bending bridges to measure the aircraft fuselage and wing bending during impact. The objective in the selection of dynamic instrumentation for the CID was to provide 352 of the highest quality transducers and remain within budget allocation. The transducers that were selected for the CID evaluation process were each subjected to rigorous laboratory acceptance tests and to aircraft fuselage section drop tests at the LaRC Impact Dynamics Research Facility. Data compiled from this series of tests showed the selected transducers to be best suited for the CID mission requirement. The transducers installation technique on the airframe proved successful. The transducer quality assurance was guaranteed through rigorous acceptance testing. Data acquired was 97.0%.

    , psychopharmacological and creative domains. For example, it would be predicted that states of insufficient alertness such as delirium would produce errors of commission (memory distortion and false memories, as with psychotic delusions), while sleep deprivation would produce errors of memory omission (memory loss). Ultimately, the main argument in favour of SEAP is that long term memory must be a complex adaptive system, and complex systems arise, are selected and sustained according to the principles of systems theory; and therefore LTM cannot be functioning in the way assumed by 'representation-consolidation' theories.

The purpose of this paper is to describe the proposed measurement techniques in sufficient detail to enable assessment of the proposed instrumentation suite and to support development of the component technologies. This paper builds upon the instrumentation chapter of the recently published FHR technology development roadmap. Locating instruments outside of the intense core radiation and high-temperature fluoride salt environment significantly decreases their environmental tolerance requirements. Under operating conditions, FHR primary coolant salt is a transparent, low-vapor-pressure liquid. Consequently, FHRs can employ standoff optical measurements from above the salt pool to assess in-vessel conditions. For example, the core outlet temperature can be measured by observing the fuel s blackbody emission. Similarly, the intensity of the core s Cerenkov glow indicates the fission power level. Short-lived activation of the primary coolant provides another means for standoff measurements of process variables. The primary coolant flow and neutron flux can be measured using gamma spectroscopy along the primary coolant piping. FHR operation entails a number of process measurements. Reactor thermal power and core reactivity are the most significant variables for process control. Thermal power can be determined by measuring the primary coolant mass flow rate and temperature rise across the core. The leading candidate technologies for primary coolant temperature measurement are Au-Pt thermocouples and Johnson noise thermometry. Clamp-on ultrasonic flow measurement, that includes high-temperature tolerant standoffs, is a potential coolant flow measurement technique. Also, the salt redox condition will be monitored as an indicator of its corrosiveness. Both

    This paper gives an overview of the CARMENES instrument and of the survey that will be carried out with it during the first years of operation. CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs) is a next-generation radial-velocity instrument under construction for the 3.5m telescope at the Calar Alto Observatory by a consortium of eleven Spanish and German institutions. The scientific goal of the project is conducting a 600-night exoplanet survey targeting ~ 300 M dwarfs with the completed instrument. The CARMENES instrument consists of two separate echelle spectrographs covering the wavelength range from 0.55 to 1.7 μm at a spectral resolution of R = 82,000, fed by fibers from the Cassegrain focus of the telescope. The spectrographs are housed in vacuum tanks providing the temperature-stabilized environments necessary to enable a 1 m/s radial velocity precision employing a simultaneous calibration with an emission-line lamp or with a Fabry-Perot etalon. For mid-M to late-M spectral types, the wavelength range around 1.0 μm (Y band) is the most important wavelength region for radial velocity work. Therefore, the efficiency of CARMENES has been optimized in this range. The CARMENES instrument consists of two spectrographs, one equipped with a 4k x 4k pixel CCD for the range 0.55 - 1.05 μm, and one with two 2k x 2k pixel HgCdTe detectors for the range from 0.95 - 1.7μm. Each spectrograph will be coupled to the 3.5m telescope with two optical fibers, one for the target, and one for calibration light. The front end contains a dichroic beam splitter and an atmospheric dispersion corrector, to feed the light into the fibers leading to the spectrographs. Guiding is performed with a separate camera; on-axis as well as off-axis guiding modes are implemented. Fibers with octagonal cross-section are employed to ensure good stability of the output in the presence of residual guiding errors. The

    2015-01-01

    In order to analyze the light of cosmic objects, particularly at extremely great distances, spectroscopy is the workhorse of astronomy. In the era of very large telescopes, long-term investigations are mainly performed with small professional instruments. Today they can be done using self-designed spectrographs and highly efficient CCD cameras, without the need for large financial investments.   This book explains the basic principles of spectroscopy, including the fundamental optical constraints and all mathematical aspects needed to understand the working principles in detail. It covers the complete theoretical and practical design of standard and Echelle spectrographs. Readers are guided through all necessary calculations, enabling them to engage in spectrograph design. The book also examines data acquisition with CCD cameras and fiber optics, as well as the constraints of specific data reduction and possible sources of error. In closing it briefly highlights some main aspects of the research on massive s...

    2014-05-01

    Currently, the presence of volcanoes represents a threat to their local populations, and for this reason, scientific communities invest resources to monitor seismic activity of an area, and to obtain information to identify risk situations. To perform such monitoring, it can use different general purpose acquisition systems commercially available, but these devices do not meet to the specifications of reduced dimensions, low weight, low power consumption and low cost. These features allow the system works in autonomous mode for a long period of time, and it makes easy to be carried and to be installed. In the line of designing a volcanic acquisition system with the previously mentioned specifications, exists the Volcanology Department of CSIC, developers of a system with some of these specifications. The objective of this work is to improve the energy consumption requirements of the previous system, providing three channels of data acquisition and with the possibility to transmit data acquisition via radio frequency to a base station, allowing operation it in remote mode. The developed acquisition system consists of three very low-power acquisition modules of Texas Instruments (ADS1246), and this is designed to capture information of the three coordinate axes. A microprocessor also of Texas Instruments (MSP430F5438) is used to work in low-power, due to it is ready to run this consumption and also takes advantage the power save mode in certain moments when system is not working. This system is configurable by serial port, and it has a SD memory to storage data. Contrast to the previous system, it has a RF communication module incorporated specially to work in remote mode of Lynx (YLX-TRM8053-025-05), and boasts also with a GPS module which keeps the time reference synchronized with module of SANAV (GM-1315LA). Thanks to this last selection of components, it is designed a small system about 106 x 106 mm. Assuming that the power supply system is working during all the

    The past year's contribution from Dr. Kaukler's experimental effort consists of these 5 parts: a) Construction and proof-of-concept testing of a novel shearing plate viscometer designed to produce small shear rates and operate at elevated temperatures; b) Preparing nonlinear polymeric materials to serve as standards of nonlinear Theological behavior; c) Measurements and evaluation of above materials for nonlinear rheometric behavior at room temperature using commercial spinning cone and plate viscometers available in the lab; d) Preparing specimens from various forms of pitch for quantitative comparative testing in a Dynamic Mechanical Analyzer, Thermal Mechanical Analyzer; and Archeological Analyzer; e) Arranging to have sets of pitch specimens tested using the various instruments listed above, from different manufacturers, to form a baseline of the viscosity variation with temperature using the different test modes offered by these instruments by compiling the data collected from the various test results. Our focus in this project is the shear thinning behavior of ZBLAN glass over a wide range of temperature. Experimentally, there are no standard techniques to perform such measurements on glasses, particularly at elevated temperatures. Literature reviews to date have shown that shear thinning in certain glasses appears to occur, but no data is available for ZBLAN glass. The best techniques to find shear thinning behavior require the application of very low rates of shear. In addition, because the onset of the thinning behavior occurs at an unknown elevated temperature, the instruments used in this study must provide controlled low rates of shear and do so for temperatures approaching 600 C. In this regard, a novel shearing parallel plate viscometer was designed and a prototype built and tested.

    This investigation represents an attempt to design and validate a skill acquisition model for the nurse educator role. The preparation and role development of nurse educators has become a significant focus for the profession.The NLN Nurse Educator Competencies and skill acquisition theory provide a basis for studying skill acquisition among nurse educators. A total of 339 nurse educators from North Carolina and West Virginia were surveyed using an instrument designed to assess skill among nurse educators. The survey discriminated among five levels of skill (novice, advanced beginner, competent, proficient, and expert). Participants reported a proficient level of total skill acquisition and a proficient level for each of the eight NLN Nurse Educator Competencies. Internal consistency for the survey tool was high at .977. Results of this study add to the body of knowledge of skill acquisition, role development, and transition.The study provides a unique method to study skill acquisition.

    Full Text Available Many have held the Acquisition of Concepts Thesis (ACT that concept acquisition can change perceptual experience. This paper explains the close relation of ACT to ADT, the thesis that acquisition of dispositions to quickly and reliably recognize a kind of thing can change perceptual experience. It then states a highly developed argument given by Siegel (2010 which, if successful, would offer strong support for ADT and indirect support for ACT. Examination of this argument, however, reveals difficulties that undermine its promise. Distinctions made in this examination help to clarify an alternative view that denies ADT and ACT while accepting that long exposure to a class of materials may induce changes in phenomenology that lie outside perceptual experience itself.

    The computational approach to syntactic acquisition can be fruitfully pursued by integrating results and perspectives from computer science, linguistics, and developmental psychology. In this article, we first review some key results in computational learning theory and their implications for language acquisition. We then turn to examine specific learning models, some of which exploit distributional information in the input while others rely on a constrained space of hypotheses, yet both approaches share a common set of characteristics to overcome the learning problem. We conclude with a discussion of how computational models connects with the empirical study of child grammar, making the case for computationally tractable, psychologically plausible and developmentally realistic models of acquisition.

    1978-01-01

    Think of guitars and you think of rock and country music, or the vigorous rhythms of the gypsy flamenco, or perhaps the classical strumming of a Segovia. About the last thing you would associate with guitars is aerospace technology. Yet there is a connection. A whole family of quality guitars is an outgrowth of helicopter rotor research conducted for the military services and NASA by an aerospace contractor. These musical spinoffs, commercially available and rapidly gaining in popularity, are the Ovation guitar line, manufactured by Ovation Instruments, Inc., Bloomfield, Connecticut. Ovation Instruments is a subsidiary of Kaman Corporation, a diversified company originally formed to develop and build helicopters. A helicopter's rotor system, with thousands of moving parts, is highly susceptible to vibration. For rotor efficiency, vibration must be "dampened," or reduced. Like other helicopter builders, Kaman Corporation spent years of research toward that end. The technology thus developed, together with the availability of staff experts in vibration engineering, sparked an idea in the mind of the company's president and founder, Charles H. Karnan. A guitarist of professional caliber, Kaman reasoned that vibration-dampening technology could be turned around to enhance vibration and thereby produce a guitar with superior sound.

    2012-07-01

    The Q/U Imaging ExperimenT (QUIET) is designed to measure polarization in the Cosmic Microwave Background, targeting the imprint of inflationary gravitational waves at large angular scales ({approx}1{sup o}). Between 2008 October and 2010 December, two independent receiver arrays were deployed sequentially on a 1.4m side-fed Dragonian telescope. The polarimeters which form the focal planes use a highly compact design based on High Electron Mobility Transistors (HEMTs) that provides simultaneous measurements of the Stokes parameters Q, U, and I in a single module. The 17-element Q-band polarimeter array, with a central frequency of 43.1 GHz, has the best sensitivity (69 {mu}Ks{sup 1/2}) and the lowest instrumental systematic errors ever achieved in this band, contributing to the tensor-to-scalar ratio at r < 0:1. The 84-element W-band polarimeter array has a sensitivity of 87 {mu}Ks{sup 1/2} at a central frequency of 94.5 GHz. It has the lowest systematic errors to date, contributing at r < 0:01. The two arrays together cover multipoles in the range {ell} {approx} 25 -- 975. These are the largest HEMT-based arrays deployed to date. This article describes the design, calibration, performance of, and sources of systematic error for the instrument.

    Sall, Ken; Ames, Troy; Warsaw, Craig; Koons, Lisa; Shafer, Richard

    1998-01-01

    The Instrument Remote Control (IRC) project ongoing at NASA's Goddard Space Flight Center's (GSFC) Information Systems Center (ISC) supports NASA's mission by defining an adaptive intranet-based framework that provides robust interactive and distributed control and monitoring of remote instruments. An astronomical IRC architecture that combines the platform-independent processing capabilities of Java with the power of Extensible Markup Language (XML) to express hierarchical data in an equally platform-independent, as well as human readable manner, has been developed. This architecture is implemented using a variety of XML support tools and Application Programming Interfaces (API) written in Java. IRC will enable trusted astronomers from around the world to easily access infrared instruments (e.g., telescopes, cameras, and spectrometers) located in remote, inhospitable environments, such as the South Pole, a high Chilean mountaintop, or an airborne observatory aboard a Boeing 747. Using IRC's frameworks, an astronomer or other scientist can easily define the type of onboard instrument, control the instrument remotely, and return monitoring data all through the intranet. The Astronomical Instrument Markup Language (AIML) is the first implementation of the more general Instrument Markup Language (IML). The key aspects of our approach to instrument description and control applies to many domains, from medical instruments to machine assembly lines. The concepts behind AIML apply equally well to the description and control of instruments in general. IRC enables us to apply our techniques to several instruments, preferably from different observatories.

  1. Skill acquisition of manual wheelchair propulsion: initial motor learning

    Directory of Open Access Journals (Sweden)

    HEJ VEEGER Dirkjan

    2011-12-01

    Full Text Available Changes in propulsion technique due to motor learning might account for a higher mechanical efficiency (ME, the ratio of internal power over external power. The changes in ME and propulsion technique were studied in a learning experiment, three times a week for eight minutes, with nine able-bodied subjects, simulating early rehabilitation. Instrumented wheels measured three-dimensional forces and torques on the handrim. During practice peak torques were reduced, work per cycle increased, while push frequency decreased, at a stable power output and speed of the treadmill. Over the three weeks of practice propulsion technique kept changing in combination with an increase of ME. Results suggest skill acquisition because of motor learning. The rise in ME seems logically related to propulsion technique, but is not yet fully understood. More insight in motor learning and skill acquisition will contribute to understanding and optimizing rehabilitation strategies in the light of wheelchair provision in early rehabilitation.

Each category includes a number of factors. The factors such as motivation, age, learning strategies and others such as personality, aptitude are also mutually related. Among all of those factors, motivation plays a very im⁃portant role in the second language acquisition. In this essay, the author will discuss the key factors that affect the outcome of the process.

    In principle, a child can seemingly easily acquire any given language. First language acquisition follows a certain pattern which to some extent is found to be language independent. Since time immemorial, it has been of interest why children are able to acquire language so easily. Different disciplinary and methodological orientations addressing this question can be identified. A selective literature search in PubMed and Scopus was carried out and relevant monographies were considered. Different, partially overlapping phases can be distinguished in language acquisition research: whereas in ancient times, deprivation experiments were carried out to discover the "original human language", the era of diary studies began in the mid-19th century. From the mid-1920s onwards, behaviouristic paradigms dominated this field of research; interests were focussed on the determination of normal, average language acquisition. The subsequent linguistic period was strongly influenced by the nativist view of Chomsky and the constructivist concepts of Piaget. Speech comprehension, the role of speech input and the relevance of genetic disposition became the centre of attention. The interactionist concept led to a revival of the convergence theory according to Stern. Each of these four major theories--behaviourism, cognitivism, interactionism and nativism--have given valuable and unique impulses, but no single theory is universally accepted to provide an explanation of all aspects of language acquisition. Moreover, it can be critically questioned whether clinicians consciously refer to one of these theories in daily routine work and whether therapies are then based on this concept. It remains to be seen whether or not new theories of grammar, such as the so-called construction grammar (CxG), will eventually change the general concept of language acquisition.

    The Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument is a pod-based Lband polarimetric synthetic aperture radar (SAR), specifically designed to acquire airborne repeat track SAR data for differential interferometric measurements. This instrument is currently installed on the NASA Gulfstream- III (G-III) aircraft with precision real-time Global Positioning System (GPS) and a sensor-controlled flight management system for precision repeat-pass data acquisitions. UAVSAR has conducted engineering and preliminary science data flights since October 2007 on the G-III. We are porting the radar to the Global Hawk Unmanned Airborne Vehicle (UAV) to enable long duration/long range data campaigns. We plan to install two radar pods (each with its own active array antenna) under the wings of the Global Hawk to enable the generation of precision topographic maps and single pass polarimetric-interferometry (SPI) providing vertical structure of ice and vegetation. Global Hawk's range of 8000 nm will enable regional surveys with far fewer sorties as well as measurements of remote locations without the need for long and complicated deployments. We are also developing P-band polarimetry and Ka-band single-pass interferometry capabilities on UAVSAR by replacing the radar antenna and front-end electronics to operate at these

    A bioimpedance-controlled concept for bone cement milling during revision total hip replacement is presented. Normally, the surgeon manually removes bone cement using a hammer and chisel. However, this procedure is relatively rough and unintended harm may occur to tissue at any time. The proposed bioimpedance-controlled surgical instrumentation improves this process because, for example, most risks associated with bone cement removal are avoided. The electrical bioimpedance measurements enable online process-control by using the milling head as both a cutting tool and measurement electrode at the same time. Furthermore, a novel integrated surgical milling tool is introduced, which allows acquisition of electrical bioimpedance data for online control; these data are used as a process variable. Process identification is based on finite element method simulation and on experimental studies with a rapid control prototyping system. The control loop design includes the identified process model, the characterization of noise as being normally distributed and the filtering, which is necessary for sufficient accuracy ( ±0.5 mm). Also, in a comparative study, noise suppression is investigated in silico with a moving average filter and a Kalman filter. Finally, performance analysis shows that the bioimpedance-controlled surgical instrumentation may also performs effectively at a higher feed rate (e.g., 5 mm/s).

    The Astronomical Instrumentation System Markup Language (AISML) is an Extensible Markup Language (XML) based file format for maintaining and exchanging information about astronomical instrumentation. The factors behind the need for an AISML are first discussed followed by the reasons why XML was chosen as the format. Next it's shown how XML also provides the framework for a more precise definition of an astronomical instrument and how these instruments can be combined to form an Astronomical Instrumentation System (AIS). AISML files for several instruments as well as one for a sample AIS are provided. The files demonstrate how AISML can be utilized for various tasks from web page generation and programming interface to instrument maintenance and quality management. The advantages of widespread adoption of AISML are discussed.

    1994-03-01

    This paper describes the design and operation of a fast, flexible, non-contact, eye-safe laser ranging instrument useful in a variety of industrial metrology situations, such as in-process machining control and part inspection. The system has variable computer-controlled standoff and depth of field, and can obtain 3-D images of surfaces within a range of from 1.5 ft to almost 10 ft from the final optical element. The minimum depth of field is about 3.5 in. at 1.5 ft and about 26 in. at the far range. The largest depth of field for which useful data are available is about 41 in. Resolution, with appropriate averaging, is about one part in 4000 of the depth of field, which implies a best case resolution for this prototype of 0.00075 in. System flexibility is achieved by computer controlled relative positioning of optical components.

  17. Portable musical instrument amplifier

    Christian, David E. (Danbury, CT)

    1990-07-24

    The present invention relates to a musical instrument amplifier which is particularly useful for electric guitars. The amplifier has a rigid body for housing both the electronic system for amplifying and processing signals from the guitar and the system's power supply. An input plug connected to and projecting from the body is electrically coupled to the signal amplifying and processing system. When the plug is inserted into an output jack for an electric guitar, the body is rigidly carried by the guitar, and the guitar is operatively connected to the electrical amplifying and signal processing system without use of a loose interconnection cable. The amplifier is provided with an output jack, into which headphones are plugged to receive amplified signals from the guitar. By eliminating the conventional interconnection cable, the amplifier of the present invention can be used by musicians with increased flexibility and greater freedom of movement.

    2008-01-01

    The international Muon Ionization Cooling Experiment (MICE) will carry out a systematic investigation of ionization cooling of a muon beam. As the emittance measurement will be done on a particle-by-particle basis, sophisticated beam instrumentation is needed to measure particle coordinates and timing vs RF. A PID system based on three time-of-flight stations, two Aerogel Cerenkov detectors and a KLOE-like calorimeter has been constructed in order to keep beam contamination ($e, \\pi$) well below 1%. The MICE time-of-flight system will measure timing with a resolution better than 70 ps per plane, in a harsh environment due to high particle rates, fringe magnetic fields and electron backgrounds from RF dark current.

    Delagi, B. A.; Saraiya, N.; Nishimura, S.; Byrd, G.

    1987-01-01

    Simulation of systems at an architectural level can offer an effective way to study critical design choices if (1) the performance of the simulator is adequate to examine designs executing significant code bodies, not just toy problems or small application fragements, (2) the details of the simulation include the critical details of the design, (3) the view of the design presented by the simulator instrumentation leads to useful insights on the problems with the design, and (4) there is enough flexibility in the simulation system so that the asking of unplanned questions is not suppressed by the weight of the mechanics involved in making changes either in the design or its measurement. A simulation system with these goals is described together with the approach to its implementation. Its application to the study of a particular class of multiprocessor hardware system architectures is illustrated.

Four intact ESL classes were divided into one control group and three treatment groups (keyword, semantic, and keyword-semantic. These Afrikaans-speaking standard 6 pupils then received 4 days of instruction. Both multiplechoice and cued-recall instruments were used to measure effects both 1 day and 9 days after instruction. The results indicated that for both the multiple-choice and cued-recall tests the combined keyword-semantic strategy differed statistically Significantly as well as practically significantly from the keyword method. The results, therefore, suggest that the combined keyword-semantic strategy increased retention above the other strategies.

    2007-12-01

    Comments on the article by J. T. Jost, which argued that the end-of-ideology claims that emerged in the aftermath of World War II were both incorrect and detrimental to the field of political psychology. M. Glassman and D. Karno make three critical points. First, Jost objectified ideology as a grand strategy implemented at the individual level, rather than as an instrument used for a specific purpose in activity. In doing so, he set ideology up as an "object" that guides human behavior rather than as a rational part of human experience. Second, they take issue with the idea that, because somebody acts in a manner that can be categorized as ideological, there actually is such a thing as ideology separate from that event and/or political experience and that psychologists ought to understand the meaning of ideology in order to understand future human activities as outside observers. Third, Jost seems to see this objective ideology as a unidirectional, causal mechanism for activity, a mechanism that assumes individuals act according to ideology, which eclipses the possibility that immediate ideological positions are the residue of purposeful activity. Glassman and Karno suggest that it may be better to take a pluralistic view of ideology in human action. Where ideology does exist, it is as a purposeful instrument--part of a logically based action to meet some ends-in-view--a mixture of immediate goals tied to secondary belief systems (which have been integrated to serve the material purposes of the purveyors of these ideologies). So if we are to understand ideology, we can only understand it through its use in human activity. (Copyright) 2007 APA.

    The acquisition and storage of buffer gases (primarily argon and nitrogen) from the Mars atmosphere provides a valuable resource for blanketing and pressurizing fuel tanks and as a buffer gas for breathing air for manned missions. During the acquisition of carbon dioxide (CO2), whether by sorption bed or cryo-freezer, the accompanying buffer gases build up in the carbon dioxide acquisition system, reduce the flow of CO2 to the bed, and lower system efficiency. It is this build up of buffer gases that provide a convenient source, which must be removed, for efficient capture Of CO2 Removal of this buffer gas barrier greatly improves the charging rate of the CO2 acquisition bed and, thereby, maintains the fuel production rates required for a successful mission. Consequently, the acquisition, purification, and storage of these buffer gases are important goals of ISRU plans. Purity of the buffer gases is a concern e.g., if the CO, freezer operates at 140 K, the composition of the inert gas would be approximately 21 percent CO2, 50 percent nitrogen, and 29 percent argon. Although there are several approaches that could be used, this effort focused on a hollow-fiber membrane (HFM) separation method. This study measured the permeation rates of CO2, nitrogen (ND, and argon (Ar) through a multiple-membrane system and the individual membranes from room temperature to 193K and 10 kpa to 300 kPa. Concentrations were measured with a gas chromatograph that used a thermoconductivity (TCD) detector with helium (He) as the carrier gas. The general trend as the temperature was lowered was for the membranes to become more selective, In addition, the relative permeation rates between the three gases changed with temperature. The end result was to provide design parameters that could be used to separate CO2 from N2 and Ar.

Although there are several approaches that could be used, this effort focused on a hollow-fiber membrane (HFM) separation method. This study measured the permeation rates of CO2, nitrogen (N2), and argon (Ar) through a multiple-membrane system and the individual membranes from room temperature to 193 K and 10 kPa to 300 kPa. Concentrations were measured with a gas chromatograph. The end result was data necessary to design a system that could separate CO2, N2, and Ar. .

    The use of nickel-titanium rotary instrument systems has gained popularity over the past 10 years. One of these instrument systems is the LightSpeed (LightSpeed Technology, Inc, San Antonio, TX). One drawback for all nickel-titanium rotary instruments is the incidence of instrument separation. The purpose of this study was to evaluate the incidence of nonretrievable instrument separation using the LightSpeed system in a clinical setting. A total of 3543 canals were treated over a 24 month period and during that time, 46 LightSpeed instruments were separated and found to be nonretrievable, resulting in a separation rate of 1.30%. This rate was lower than previous reported studies.

  9. The role of the anterior, mediodorsal, and parafascicular thalamus in instrumental conditioning

    Full Text Available The traditional animal model of instrumental behaviour has focused almost exclusively on structures within the cortico-striatal network and ignored the contributions of various thalamic nuclei despite large and specific connections with each of these structures. One possible reason for this is that the thalamus has been conventionally viewed as a mediator of general processes, such as attention, arousal and movement, that are not easily separated from more cognitive aspects of instrumental behaviour. Recent research has, however, begun to separate these roles. Here we review the role of three thalamic nuclei in instrumental conditioning: the anterior, the mediodorsal, and parafascicular thalamic nuclei. Early research suggested that anterior thalamic nuclei might regulate aspects of instrumental behaviour but, on review, we suggest that the types of tasks used in these studies were more likely to recruit Pavlovian processes. Indeed lesions of anterior thalamic nuclei have been found to have no effect on performance in instrumental free-operant tasks. By contrast the mediodorsal thalamus has been found to play a specific and important role in the acquisition of goal-directed action. We propose this role is related to its connections with prelimbic cortex and present new data that directly implicates this circuit in the acquisition of goal-directed actions. Finally we review evidence suggesting the parafascicular thalamic nucleus, although not critical for the acquisition or performance of instrumental actions, plays a specific role in regulating action flexibility.

    The Centre de Recherche Astrophysique de Lyon (CRAL) has recently developed two instrument simulators for spectrographic instruments. They are based on Fourier optics, and model the whole chain of acquisition, taking into account both optical aberrations and diffraction effects, by propagating a wavefront through the instrument, according to the Fourier optics concept. One simulates the NIRSpec instrument, a near-infrared multi-object spectrograph for the future James Webb Space Telescope (JWST). The other one models the Multi Unit Spectroscopic Explorer (MUSE) instrument, a second-generation integral-field spectrograph for the Very Large Telescope (VLT). The two simulators have been developed in different contexts (subcontracted versus developed internally), and for very different instruments (space-based versus ground-based), which strengthen the CRAL experience. This paper describes the lessons learned while developing these simulators: development methods, phasing with the project, points to focus on, getting data, interacting with scientists and users, etc.

    Laser Induced Breakdown Detection (LIBD) is one of the quantification techniques for colloids. There are two ways of detection in LIBD: optical detection and acoustic detection. LIBD is based on the detection of plasma emission due to the interaction between particle and laser beam. In this research, the changing of light intensity during plasma formations was detected by a photodiode sensor. A photo emission data acquisition system was built to collect and transform them into digital counts. The real-time system used data acquisition device National Instrument DAQ 6009 and LABVIEW software. The system has been tested on distilled water and tap water samples. The result showed 99.8% accuracy by using counting technique in comparison to the acoustic detection with sample rate of 10 Hz, thus the acquisition system can be applied as an alternative method to the existing LIBD acquisition system.

    The safety and the control of the reactor need to master the nuclear power from the core radiation measurement. According to the reactor dimensions and conception, the nuclear parameters monitoring is realized through two instrumentation systems: the ex-core instrumentation system which use detector placed outside of the core and the in-core instrumentation system. This paper deals with the ex-core systems based on neutronic measurements and details the detectors choice, the treatment circuits, data processing, realizations in France and also example of the Wwr reactor instrumentation.

    Full Text Available Objectives: The goal of this project was to develop the first disease-specific instrument for the evaluation of quality of life in chronic pancreatitis. Methods: Focus groups and interview sessions were conducted, with chronic pancreatitis patients, to identify items felt to impact quality of life which were subsequently formatted into a paper-and-pencil instrument. This instrument was used to conduct an online survey by an expert panel of pancreatologists to evaluate its content validity. Finally, the modified instrument was presented to patients during precognitive testing interviews to evaluate its clarity and appropriateness. Results: In total, 10 patients were enrolled in the focus groups and interview sessions where they identified 50 items. Once redundant items were removed, the 40 remaining items were made into a paper-and-pencil instrument referred to as the Pancreatitis Quality of Life Instrument. Through the processes of content validation and precognitive testing, the number of items in the instrument was reduced to 24. Conclusions: This marks the development of the first disease-specific instrument to evaluate quality of life in chronic pancreatitis. It includes unique features not found in generic instruments (economic factors, stigma, and spiritual factors. Although this marks a giant step forward, psychometric evaluation is still needed prior to its clinical use.

    CLIC [1] (Compact Linear Collider) is a world-wide collaboration to study the next terascale lepton collider, relying upon a very innovative concept of two-beamacceleration. In this scheme, the power is transported to the main accelerating structures by a primary electron beam. The Two Beam Module (TBM) is a compact integration with a high filling factor of all components: RF, Magnets, Instrumentation, Vacuum, Alignment and Stabilization. This paper describes the very challenging aspects of designing the compact system to serve as a dedicated Acquisition & Control Module (ACM) for all signals of the TBM. Very delicate conditions must be considered, in particular radiation doses that could reach several kGy in the tunnel. In such severe conditions shielding and hardened electronics will have to be taken into consideration. In addition, with more than 300 ADC&DAC channels per ACM and about 21000 ACMs in total, it appears clearly that power consumption will be an important issue. It is also obvious that...

    The introduction of the new Field Programmable Gate Array (FPGA) cards by National Instruments has made it possible for the first time to develop reconfigurable custom data acquisition hardware easily with the LabVIEW programming environment. Data acquisition issues such as precise timing for scanning and operating system latencies can now be easily overcome using this new technology because the data acquisition software is embedded in the FPGA chip on the card. In this paper we present the first results of the new data acquisition system developed at the Centre for Ion Beam Applications (CIBA), National University of Singapore using the new National Instruments cards in conjunction with rack mountable Wilkinson type ADCs.

    Pneumatic, hydraulic and allied instrumentation schemes have given way to electronic schemes in recent years thanks to the rapid strides in electronics and allied areas. Principles, design and applications of such state-of-the-art instrumentation schemes form the subject matter of this book. Through representative examples, the basic building blocks of instrumentation schemes are identified and each of these building blocks discussed in terms of its design and interface characteristics. The common generic schemes synthesized with such building blocks are dealt with subsequently. This forms the scope of Part I. The focus in Part II is on application. Displacement and allied instrumentation, force and allied instrumentation and process instrumentation in terms of temperature, flow, pressure level and other common process variables are dealt with separately and exhaustively. Despite the diversity in the sensor principles and characteristics and the variety in the applications and their environments, it is possib...
