  5. MIDAS: Multiple Instrument Data Acquisition Software user guide

    Mikkelson, K.A.

    1988-08-01

    MIDAS (Multiple Instrument Data Acquisition Software) is a software package which supports data acquisition and analysis. It is similar in function to AQD but is written in SPS Basic, is simpler to operate, and provides an alternative approach when AQD is not appropriate. MIDAS can support a wide variety of recorders, and can be used in either stand-alone or networked systems. Also, adding new recording instruments to the package can be accomplished with minimal effort.

  6. Philosophy of clinical psychopharmacology.

    Aragona, Massimiliano

    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

  8. Ethical issues in psychopharmacology

    McHenry, L

    2006-01-01

    The marketing of selective serotonin reuptake inhibitors in the psychopharmacological industry presents a serious moral problem for the corporate model of medicine. In this paper I examine ethical issues relating to the efficacy and safety of these drugs. Pharmaceutical companies have a moral obligation to disclose all information in their possession bearing on the true risks and benefits of their drugs. Only then can patients make fully informed decisions about their treatment.

    2012-03-01

    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.

  14. Psychopharmacology in Primary Care Settings.

    Benich, Joseph J; Bragg, Scott W; Freedy, John R

    2016-06-01

    Psychopharmacology requires clinicians to stay current on the latest guidelines and to use dynamic treatment strategies. Psychiatric conditions are prevalent in the primary care population. Choice of treatment with psychopharmacology should be based on controlling the patient's predominant symptoms while taking into consideration patient age, treatment compliance, patient past response to treatments, dosing frequency, patient preference, medication side effects, potential medication interactions, drug precautions/warnings, and cost. Response to therapy, as well as side effects, needs to be evaluated at regular intervals. The goal is to minimize symptoms and return patients to their maximal level of functioning. PMID:27262011

  20. Acquisition of advanced-technology medical instrumentation by developing countries

    The increasing complexity and cost of new imaging technology makes the purchase of such equipment an undertaking with serious financial and operational consequences. Aside from the basic clinical needs, a number of practical questions must be addressed by the knowledgeable buyer. The natural tendency to avoid used or reconditioned equipment should not prevent the buyer from considering this type of equipment. However, it is essential to obtain the vendor's firm commitment to provide ongoing support of the equipment by making maintenance personnel, spare parts and service contracts available. The complexity of present-day equipment may require significant upgrading of the electrical system in the intended installation site. Air conditioning may be required. Adequate training of physicians and technologists must be provided in order for the equipment to be properly operated so that clinical results are not compromised. This document points out different aspects of acquisition of advanced medical equipment - such as X-ray equipment - that should be taken into consideration in order to avoid problems after its installation. 8 refs

  1. 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

  2. [Psychopharmacological treatment of bipolar disease].

    Licht, Rasmus W; Vestergaard, Per

    2002-05-01

    This paper gives an update on the psychopharmacological treatment of bipolar disorder. The antimanic efficacy of lithium is well documented. The same applies to valproate, which is also efficacious in mixed mania. Conventional antipsychotics act fast in mania and do not require blood tests, but they have considerable neurological side effects. The newer antipsychotics, olanzapine, risperidone, and ziprasidone, have also been shown to have antimanic efficacy. Clozapine is extremely effective, also when other treatment fails. For the treatment of bipolar depression, lithium, lamotrigine, and antidepressants all seem to work, but antidepressants may sometimes precipitate mania or worsen the course of illness. For prophylaxis, lithium is still to be considered the first drug of choice. However, for several reasons, for instance treatment failure or side effects, long-term treatment with antiepileptics may often be necessary. Among the antiepileptics, carbamazepine, valproate, and lamotrigine are the best studied. PMID:12025705

  3. Effectiveness of psychopharmacology in Anorexia Nervosa treatment

    Zadka Lukasz

    2015-06-01

    Full Text Available The eating disorder that generates the highest death rate is that of anorexia nervosa, and current treatment is a combination of equalization of somatic state and patient education. Moreover, psychical symptoms occurring in the course of anorexia nervosa are thought to have a crucial influence on the course of the disease. Hence, in medical literature, the effectiveness of psychotherapeutic interventions is also widely described. Still, the implementation of appropriate psychopharmacology is now considered an additional method of treatment, rather than a therapy of choice. Yet, in spite of many years of research, there are no absolute recommendations given, nor are instructions within the scope of psychopharmacological treatment proffered, although the selection of psychopharmacological items must respect both the patient’s psychic and somatic states. In recent years, the popularity of psychopharmacological treatment has increased; therefore, we feel that it is justified to present the latest scientific information in this respect.

  4. The collection and analysis of transient test data using the mobile instrumentation data acquisition system (MIDAS)

    2000-04-01

    The PESCA Instrument Control and Acquisition System (PICAS) design, building and tests are presented. The purpose of the PESCA instrument is the study of the Solar Energetic Particles and the Anomalous Cosmic Rays. It is, therefore, a satellite on-board instrument. The PICAS is basically a computer, composed of a microprocessor with a memory block and a set of interfaces for the communication with the rest of the instrument and the satellite. The PICAS manages all the comunication processes with the satellite, that comprises the order reception from the ground station, and the telemetry sending, that includes scientific data and housekeeping data. By means of telecommands, the PICAS is completely controllable from the ground. The PICAS is also a reliable data acquisition system that guarantees the correct reception of the Cosmic Rays data collected in the ground.

  6. The development of a mobile instrumentation data acquisition system for use in cask testing

    Packagings for transporting radioactive materials are required to survive exposure to environments. Package designers investigate design and analysis problems through structural and thermal testing of various components or models, using instrumentation to measure physical responses. The acquisition of high quality data from instrumentation is an essential part of the testing activity. To provide this quality of data, we are developing a mobile instrumentation data acquisition system dedicated for use in cask testing. This system is designed to acquire and analyze structural and thermal test data, and to provide leakage measurement capabilities. The mobile instrumentation system is housed in a 13.4m (44-ft) trailer transporter, which is self-contained with air conditioning, heating, and halon fire protection systems. External power from a commercial or motor generator source is line conditioned prior to distribution to the data acquisition equipment inside the trailer, and lightning protection is provided at the point where the measurement devices interface to the data acquisition equipment. This system is capable of performing data analyses and display of the acquired information within thirty minutes after an experiment

  15. Comparison of Data Acquisition Strategies on Quadrupole Ion Trap Instrumentation for Shotgun Proteomics

    Canterbury, Jesse D.; Merrihew, Gennifer E.; MacCoss, Michael J.; Goodlett, David R.; Shaffer, Scott A.

    2014-12-01

    The most common data collection in shotgun proteomics is via data-dependent acquisition (DDA), a process driven by an automated instrument control routine that directs MS/MS acquisition from the highest abundant signals to the lowest. An alternative to DDA is data-independent acquisition (DIA), a process in which a specified range in m/ z is fragmented without regard to prioritization of a precursor ion or its relative abundance in the mass spectrum, thus potentially offering a more comprehensive analysis of peptides than DDA. In this work, we evaluate both DDA and DIA on three different linear ion trap instruments: an LTQ, an LTQ modified with an electrodynamic ion funnel, and an LTQ Velos. These instruments represent both older (LTQ) and newer (LTQ Velos) ion trap designs (i.e., linear versus dual ion traps, respectively), and allow direct comparison of peptide identifications using both DDA and DIA analysis. Further, as the LTQ Velos has an enhanced "S-lens" ion guide to improve ion flux, we found it logical to determine if the former LTQ model could be leveraged by improving sensitivity by modifying with an electrodynamic ion guide of significantly different design to the S-lens. We find that the ion funnel enabled LTQ identifies more proteins in the insoluble fraction of a yeast lysate than the other two instruments in DIA mode, whereas the faster scanning LTQ Velos performs better in DDA mode. We explore reasons for these results, including differences in scan speed, source ion optics, and linear ion trap design.

  16. Coherent diffraction microscopy at SPring-8: instrumentation, data acquisition and data analysis

    An instrumentation and data analysis review of coherent diffraction microscopy at SPring-8 is given. This work will be of interest to those who want to apply coherent diffraction imaging to studies of materials science and biological samples. Since the first demonstration of coherent diffraction microscopy in 1999, this lensless imaging technique has been experimentally refined by continued developments. Here, instrumentation and experimental procedures for measuring oversampled diffraction patterns from non-crystalline specimens using an undulator beamline (BL29XUL) at SPring-8 are presented. In addition, detailed post-experimental data analysis is provided that yields high-quality image reconstructions. As the acquisition of high-quality diffraction patterns is at least as important as the phase-retrieval procedure to guarantee successful image reconstructions, this work will be of interest for those who want to apply this imaging technique to materials science and biological samples

  19. Testing of a 1:6-scale concrete containment model: Instrumentation, data acquisition, and pressure control

    A 1:6-scale model of a reactor containment building was tested by Sandia National Laboratories (Sandia) as part of an NRC-sponsored program whose objective is to qualify methods for predicting the response of light water reactor containment buildings subjected to severe accidents. This model was designed and built to the American Society of Mechanical Engineers (ASME) code by United Engineers and Constructors, Inc. It had several features representative of a prototypical reinforced containment, including equipment hatches, personnel airlocks, several small piping penetrations, and a steel liner. This was the largest and most heavily instrumented containment model ever tested. Over 1200 channels of instrumentation were utilized to assess the model's behavior during testing. The final test was conducted continuously for approximately 32 hours, during which time the model was pressurized with nitrogen gas to its ultimate capacity. The pressure control system was used to pressurize the model in steps and after each step the transducers were scanned to record the model's response. This paper decribes the conduct and outcome of the test as well as the instumentation that was used to obtain the test data. The selection, installation, protection, and performance of the instrumentation are discussed. The data acquisition and pressure control systems are also described

  20. Data acquisition and control using National Instruments' ''LabVIEW'' software

    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.

    2016-03-01

    Full Text Available A low-power and low-noise dynamic instrumentation amplifier (IA for biopotential acquisition is presented. A dynamic IA that can reduce power consumption with a timely piecewise power-gating method, and noise level with an alternating input and chopper stabilization technique is fabricated with a 0.13-μm CMOS. Using the reconfigurable architecture of the IA, various combinations of the low-noise schemes are investigated. The combination of power gating and chopper stabilization shows a lower noise performance than the combination of power gating and alternating input switching scheme. This dynamic IA achieved a power reduction level of 50% from 10 µA to 5 µA and a noise reduction of 90% from 9.1 µVrms to 0.92 µVrms with the combination of the power gating and chopper stabilization scheme.

  4. A digital data acquisition system for a time of flight neutron diffuse scattering instrument

    Full text. We describe the design of a digital data acquisition system built for acquiring and storing the information produced by a neutron diffuse scattering apparatus. This instrument is based on the analysis of pulsed subthermal neutron which are scattered by a solid or liquid sample, measured as function of the scattered neutron wavelength and momentum direction. The time of flight neutron intensities on 14 different angular detector positions and two fission chambers must be analyzed simultaneously for each neutron burst. A PC controlled data acquisition board system was built based on two parallel multiscannning units, each with its own add-one counting unit, and a common base time generator. The unit plugs onto the ISA bus through an interface card. Two separate counting units were designed, to avoid possible access competition between low counting rate counters at off-axis positions and the higher rate frontal 0 deg and beam monitoring counters. the first unit contains logic for 14 independent and simultaneous multi scaling inputs, with 128 time channels and dwell time per channel of 5, 10 or 20 microseconds. Sweep trigger is synchronized with an electric signal from a coil sensing the rotor. The second unit contains logic for four additional multi scalers using the same external synchronizing signal, similar in all others details to the previously described multi scalers. Basic control routines for the acquisitions were written in C and a program for spectrum display and user interface was written in C++ for a Windows 3.1 OS. A block diagram of the system is presented

  5. Wireless micropower instrumentation for multimodal acquisition of electrical and chemical neural activity.

    Mollazadeh, M; Murari, K; Cauwenberghs, G; Thakor, N

    2009-12-01

    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. PMID:23853286

  6. A LabVIEW-based data acquisition system for the UTEP/Orsay Instrumented Collimator

    Full text: We have successfully employed an instrumented collimator of aperture 2 mm for the g8a run (summer, 2001) in Hall B of Jefferson Lab, which was designed and tested by UTEP and engineered and built by the Institut de Physique Nucl ire in Orsay, France. The instrumentation of the collimator consists of four radially mounted scintillator + light guide + PMT elements possessing a left-right, up-down symmetry, which afforded the beam of photons to be precisely aligned to the central axis of the collimator. The collimator was sensitive to rather modest beam motion of the order of a few tens of microns. We made use of the physical fact that the emission angle of the coherent Bremsstrahlung photon component is correlated with its energy for enhancing the degree of polarization of the photon beam. We can extract the spectral peak by tightly collimating the beam and thereby reduce the incoherent background, which further serves to increase the degree of polarization. The maximum polar angle is limited by the opening angle of the collimator, which gives the lower limit for the coherent Bremsstrahlung photon energy. To achieve polarizations exceeding 75%, we must collimate the beam to better than one half of a characteristic angle. This means for a collimator-goniometer distance of 22 m, the aperture of the collimator should be ∼ 2 mm for an incident electron energy of Eo 5.7 GeV. We will report primarily on the bench top data acquisition system (DAQ), which interfaced LabVIEW through a SCSI connection to the VME back plane to readout CAEN QDCs. We employed this DAQ to test and calibrate the instrumented collimator. Our efforts were quite successful in that the device functioned beyond design specifications within one hour after the photon beam was directed onto the bore hole of the collimator. (Author)

    2016-09-15

    WHO defined in 1976 psychopharmaca as drugs affecting psychological functions, behaviour and self-perception. Psychopharmacology is the study of pharmacological agents that affect mental and emotional functions. Creative approach to psychopharmacotherapy reflects a transdisciplinary, integrative and person-centered psychiatry. Psychiatric disorders often occur in cardiac patients and can affect the clinical presentation and morbidity. Cardiovascular (CV) side effects (SE) caused by psychopharmaceutic agents require comprehensive attention. Therapeutic approach can increase placebo and decrease nocebo reactions. The main purpose of this review is to comprehend CV SE of psychotropic drugs (PD). Critical overview of CV SE of PD will be presented in this review. Search was directed but not limited to CV effects of psychopharmacological substances, namely antipsychotics, anxiolytics, hypnotics, sedatives, antidepressants and stimulants. Literature review was performed and data identified by searches of Medline and PubMed for period from 2004 to 2015. Only full articles and abstracts published in English were included. SE of PD are organized according to the following types of CV effects: cardiac and circulatory effects, abnormalities of cardiac repolarisation and arrhythmias and heart muscle disease. There is wide spectrum and various CV effects of PD. Results of this review are based on literature research. The reviewed data came largely from prevalence studies, case reports, and cross-sectional studies. Psychopharmacotherapy of psychiatric disorders is complex and when concomitantly present with CV disease, presentation of drug SEs can significantly contribute to illness course. Further development of creative psychopharmacotherapy is required to deal with CV effects of PD. PMID:27352209

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

    Ostowari, Cyrus

    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.

  9. Behavioral and psychopharmacological treatment of the paraphilic and hypersexual disorders.

    Krueger, Richard B; Kaplan, Meg S

    2002-01-01

    In this article, the second of a two-part series, the authors present information on the clinical assessment of individuals with paraphilias and hypersexual disorders. They review ethical considerations in the assessment and treatment of individuals with paraphilias. The role of interview and subjective and objective instruments in the assessment of individuals with paraphilias and hypersexual disorders is discussed. The authors discuss the use of penile plethysmography or phallometry, polygraphy, and viewing time assessments. Risk assessment of sexual offenders is reviewed. The authors then discuss behavioral, environmental, and psychopharmacological treatments for paraphilias and hypersexual disorders. Cognitive-behavioral therapy appears to be the most effective nonpharmacological strategy. The authors describe cognitive-behavioral techniques for decreasing and/or controlling sexual urges (e.g., satiation, covert sensitization, fading, cognitive restructuring, victim empathy therapy) as well as methods for enhancing appropriate sexual interest and arousal (e.g., social skills training, assertiveness skills training, sex education, couples therapy). The authors also discuss the role of relapse prevention therapy and 12-step programs, as well as other nonbiological therapies such as surveillance networks. The importance of providing appropriate treatment for comorbid conditions (e.g., depression, substance abuse or dependence) is stressed. The authors then review psychopharmacological treatments, including serotonin reuptake inhibitors (SRIs) and antiandrogens, in particular, the use of gonadotropin-releasing hormone (GNRH) agonists. SRIs have been studied in these disorders in an uncontrolled way and appear promising. Earlier antiandrogens (e.g., estrogen, progesterone, and cyproterone acetate) have demonstrated efficacy in the treatment of paraphilias. The newer GNRH agonists have the advantage over the earlier treatments of being available in long-acting depot

  10. Proceedings of the XIIIth IAGA Workshop on Geomagnetic Observatory Instruments, Data Acquisition, and Processing

    Love, Jeffrey J.

    2009-01-01

    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.

  12. Autonomous acquisition systems for TJ-II: controlling instrumentation with a fourth generation language

    Recently, 536 new acquisition channels, made-up of three different channel types, have been incorporated into the TJ-II data acquisition system (DAQ). Dedicated software has also been developed to permit experimentalists to program and control the data acquisition in these systems. The software has been developed using LabView and runs under the Windows 2000 operating system in both personal computer (PC) and PXI controllers. In addition, LabView software has been developed to control TJ-II VXI channels from a PC using a MXI connection. This new software environment will also aid future integration of acquisition channels into the TJ-II remote participation system. All of these acquisition devices work autonomously and are connected to the TJ-II central server via a local area network. In addition, they can be remotely controlled from the TJ-II control-room using Virtual Network Computing (VNC) software

  13. [Generic drugs in psychopharmacology: pros and cons].

    Cuenca, E; Zaragozá, F

    1999-01-01

    Legislation to facilitate process for generic products has been enacted and generic drugs have entered the market soon after the patent for the brand-name agent have expired. In every instance, the rationale has been economic since it is generally assumed that the copies are not only therapeutically equivalent but also a great deal less expensive than the original. Sometimes this may be so. In this short review several comments are made in order to establish the variables that may influence bioequivalence between the brand-name drug and its generics. Among them emphasis is given to the particle sizes, pharmaceutical supply, choice of the right excipient, in order to avoid possible interactions with the drug, ingredient quality and purity, etc. All these variables must be carefully controlled. Even so a patient who is changed from a trade name product to a generic drug (or vice versa) may respond a little differently, which is important in Psychopharmacology. Two or more products should be considered biologically equivalent only when it can demonstrated that they fulfil three conditions: that they have the same pharmaceutical properties; that they are equally effective in therapeutic use and that they are tolerated equally by patients being treated for the indicated uses. Regulatory agencies could require subsequent versions of an original therapeutic product the type of data regarding pharmacology, toxicology and chemical assessment that was mandatory for the introduction of the original.

  14. Psychopharmacologic treatment of eating disorders: emerging findings.

    McElroy, Susan L; Guerdjikova, Anna I; Mori, Nicole; Keck, Paul E

    2015-05-01

    Psychopharmacologic treatment is playing a greater role in the management of patients with eating disorders. In this paper, we review randomized, placebo-controlled trials (RCTs) conducted in anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and other eating disorders over the past 3 years. Fluoxetine remains the only medication approved for an eating disorder, that being BN. RCTs of antipsychotics in AN have had mixed results; the only agent with some evidence of efficacy is olanzapine. One study suggests dronabinol may induce weight gain in AN. Preliminary studies suggest lack of efficacy of alprazolam, dehydroepiandrosterone, or physiologic estrogen replacement in AN; erythromycin in BN; and the opioid antagonist ALKS-33 in BED. In BED with obesity or overweight, bupropion may cause mild weight loss without seizures, and chromium may improve glucose regulation. Also in BED, three RCTs suggest the stimulant prodrug lisdexamfetamine may reduce binge eating episodes, and another RCT suggests intranasal naloxone may decrease time spent binge eating. There remains a disconnection between the size of eating disorders as a public health problem and the lack of pharmacotherapy research of these conditions. PMID:25796197

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

    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.

    After participating in this educational activity, the physician should be better able to1. Prescribe the appropriate psychotropic medication to treat symptoms of ASD.2. Identify the side effects of the psychotropic medications used to treat ASD.Autism spectrum disorders (ASDs) are characterized by core deficits in social communication and language, and restrictive and repetitive behaviors that cause significant functional impairment and distress for affected individuals and their caregivers. The increasing prevalence of ASD, most recently estimated as 1 in 88 children, presents an ever-increasing burden on families, schools, medical systems, and society at large. Individuals with ASD commonly present for treatment of associated emotional and behavioral disturbances that include anxiety, symptoms of ADHD, compulsions and other repetitive behaviors, mood lability, irritability, aggression, and sleep disturbance. Psychotropic medications are widely utilized in alleviating these symptoms, though rigorous clinical trials in ASD are lacking for most areas of impairment. Strong evidence from randomized, placebo-controlled trials supports the use of atypical antipsychotics, particularly risperidone and aripiprazole, for managing severe irritability and aggression in ASD. Serotonin reuptake inhibitors are commonly used to treat anxiety and compulsions, though reports of efficacy in the literature are mixed, and behavioral side effects in children are common. Minimal evidence supports the utility of anticonvulsants and traditional mood stabilizers in managing mood lability and aggression. Stimulant and nonstimulant ADHD medications can be effective for reducing hyperactivity, inattention, and impulsivity, though to a lesser degree than in ADHD populations without ASD and with greater risk of adverse effects. Psychopharmacological interventions in development for core symptoms of autism include those that target the glutamatergic and GABAergic neurotransmitter systems and the

  18. Virtual instrumentation for monitoring the purification installation of the cryogenic pilot plant by using remote data acquisition

    The goal of this work was to develop a data acquisition system for the purifying module of the Pilot Plant for tritium and deuterium separation and acquire data over network using a National Instruments DAQ board AT-MIO-16XE-10 installed in a remote computer which is located in data acquisition room from tritium separation installation. This solution of implementation provides us with a large number of acquisitions, with many advantages from SCXI-signal conditioning. The gain is applied to the low-level signals from the SCXI module located close to the transducer, sending only high-level signals to the PC, minimizing the effects of noise on the readings. All data acquired are saved in specified files and after that are used to determine the thermodynamic parameters associated to each measuring point (entropy , enthalpy, specific heat, and occasionally, liquid fraction). With these values we analyze the performances of the compound units (heat exchangers, turbo expanders, throttle valves) of the cryogenics cycle using the temperature entropy diagram. We used the LabVIEW 4.1 TM programming for charting analyzing and saving data. The signal conditioning was chosen due to its advantages: electrical isolation transducers interfacing, signal amplification filtering and high speed channel multiplexing. (authors)

  1. Resource Prospector Instrumentation for Lunar Volatiles Prospecting, Sample Acquisition and Processing

    Captain, J.; Elphic, R.; Colaprete, A.; Zacny, Kris; Paz, A.

    2016-01-01

    Data gathered from lunar missions within the last two decades have significantly enhanced our understanding of the volatile resources available on the lunar surface, specifically focusing on the polar regions. Several orbiting missions such as Clementine and Lunar Prospector have suggested the presence of volatile ices and enhanced hydrogen concentrations in the permanently shadowed regions of the moon. The Lunar Crater Observation and Sensing Satellite (LCROSS) mission was the first to provide direct measurement of water ice in a permanently shadowed region. These missions with other orbiting assets have laid the groundwork for the next step in the exploration of the lunar surface; providing ground truth data of the volatiles by mapping the distribution and processing lunar regolith for resource extraction. This next step is the robotic mission Resource Prospector (RP). Resource Prospector is a lunar mission to investigate 'strategic knowledge gaps' (SKGs) for in-situ resource utilization (ISRU). The mission is proposed to land in the lunar south pole near a permanently shadowed crater. The landing site will be determined by the science team with input from broader international community as being near traversable landscape that has a high potential of containing elevated concentrations of volatiles such as water while maximizing mission duration. A rover will host the Regolith & Environment Science and Oxygen & Lunar Volatile Extraction (RESOLVE) payload for resource mapping and processing. The science instruments on the payload include a 1-meter drill, neutron spectrometer, a near infrared spectrometer, an operations camera, and a reactor with a gas chromatograph-mass spectrometer for volatile analysis. After the RP lander safely delivers the rover to the lunar surface, the science team will guide the rover team on the first traverse plan. The neutron spectrometer (NS) and near infrared (NIR) spectrometer instruments will be used as prospecting tools to guide

  3. PET application in psychiatry and psychopharmacology

    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

    2003-12-01

    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. The July 12th dome collapse and vulcanian explosion events were recorded at 3 of the 4

    SCK-CEN's research and development programme on instrumentation aims at evaluating the potentials of new instrumentation technologies under the severe constraints of a nuclear application. It focuses on the tolerance of sensors to high radiation doses, including optical fibre sensors, and on the related intelligent data processing needed to cope with the nuclear constraints. Main achievements in these domains in 1999 are summarised

  7. Instrumentation

    SCK-CEN's research and development programme on instrumentation involves the assessment and the development of sensitive measurement systems used within a radiation environment.

    2012-01-01

    Full Text Available Irritable bowel syndrome (IBS accounts for 25% of gastroenterology output practice, making it one of the most common disorders in this practice. Psychological and social factors may affect the development of this chronic disorder. Furthermore, psychiatric symptoms and psychiatric diseases are highly prevalent in this condition, but the approach to treating these is not always straightforward. As emphasized in the biopsychosocial model of IBS, with regard to the modulatory role of stress-related brain-gut interactions and association of the disease with psychological factors and emotional state, it proves useful to encourage psychopharmacological treatments and psychosocial therapies, both aiming at reducing stress perception. The aim of this paper is to analyze the effectiveness of psychopharmacological treatment and psychological interventions on irritable bowel syndrome.

  10. Somatic treatments excluding psychopharmacology in obsessive- compulsive disorder: a review.

    Atmaca, Murad

    2013-06-01

    Somatic treatments other than psychotropic drugs are increasingly used in the patients with obsessive compulsive disorder (OCD), however there has been little systematic review of them. Therefore, the present review deals with a variety of somatic treatment methods excluding psychotropic drugs. A literature search was performed on the PubMed database from the beginning of 1980, to September 2012, for published English, Turkish and French-language articles of somatic treatment approaches (excluding psychopharmacological agents) in the treatment of OCD. The search was carried out by using some terms in detail. Afterwards, the obtained investigations on electroconvusive therapy (ECT), deep brain stimulation (DBS), neurosurgical methods and transcranial magnetic stimulation (TMS) were presented. Although psychopharmacological treatment and psychotherapeutic approaches are primary treatment modalities in the management of OCD, other somatic treatment options seem to be used as alternatives, especially for patients with treatmentresistant OCD.

  12. The dimensional approach to clinical psychopharmacology: a polysemous concept.

    Baruch, P.; Filteau, M J; Bouchard, R H; Pourcher, E; Vincent, P.; Jouvent, R.

    1992-01-01

    The last decade has seen significant progress in the development and specific clinical application of selective psychotropes. The dimensional approach to clinical psychopharmacology views the behavioral targets of psychotropes as phenomena existing on a continuum and as components, in varying degrees, of most psychopathologies. The modern concept of dimension has been used in different contexts. In psychology it has a mathematical sense, whereas in biological psychiatry it is associated more ...

  13. Trajectory of Psychopharmacology : The role of the clinician and Industry

    Healy, David

    2003-01-01

    Psychopharmacology emerged with the discovery of chlorpromazine in 1952. This led on to the discovery of other antipsychotics, antidepressants, tranquillisers, psychedelics and other drugs. Traditional histories tell of a liberation of the insane from their asylums. This history neglects the rise and fall of antipsychiatry, and the fact that many more people are both employed in and treated by the mental health industry now than ever before. The small companies who manufactured the first drug...

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

    Kraemer, Felicitas

    2010-01-01

    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 ...

    SCK-CEN's R and D programme on instrumentation involves the development of advanced instrumentation systems for nuclear applications as well as the assessment of the performance of these instruments in a radiation environment. Particular emphasis is on the use of optical fibres as umbilincal links of a remote handling unit for use during maintanance of a fusion reacor, studies on the radiation hardening of plasma diagnostic systems; investigations on new instrumentation for the future MYRRHA accelerator driven system; space applications related to radiation-hardened lenses; the development of new approaches for dose, temperature and strain measurements; the assessment of radiation-hardened sensors and motors for remote handling tasks and studies of dose measurement systems including the use of optical fibres. Progress and achievements in these areas for 2001 are described

  16. Females' participation in psychopharmacology research as authors, editors, and subjects.

    Poling, Alan; Durgin, Amy; Bradley, Kelly P; Porter, Lindsay K; Van Wagner, Karen; Weeden, Marc; Panos, John J

    2009-04-01

    This study determined the involvement of women as first authors and other authors for every article published in Experimental and Clinical Psychopharmacology, Pharmacology Biochemistry and Behavior, and Psychopharmacology in 1991, 1996, 2001, and 2006. Their involvement as editors also was determined. Women's participation as authors, but not as editors, slightly increased over time. In 2006, 43% of first authors, 38% of other authors, and 24% of editors were women. The gender of subjects was examined for the same years and journals, but could not be determined for 6% and 9% of articles employing nonhuman and human subjects, respectively. In 2006, when subjects' gender could be determined, 77% of articles involving nonhuman subjects used only males, 9% only females, and 14% both males and females. In articles using human subjects in that same year, 17% involved only males, 6% only females, and 77% both males and females. Women researchers clearly make substantial contributions to the psychopharmacology literature, but are nonetheless underrepresented as editors. Findings regarding subjects indicate that there is growing recognition of the importance of gender as a determinant of drug effects, although the vast majority of nonhuman studies continue to involve only male subjects.

    Miniati, Mario; Mauri, Mauro; Ciberti, Agnese; Mariani, Michela Giorgi; Marazziti, Donatella; Dell'Osso, Liliana

    2016-04-01

    The aim of this review was to summarize evidence from research on psychopharmacological options for adult patients with anorexia nervosa (AN). Database searches of MEDLINE and PsycINFO (from January 1966 to January 2014) were performed, and original articles published as full papers, brief reports, case reports, or case series were included. Forty-one papers were screened in detail, and salient characteristics of pharmacological options for AN were summarized for drug classes. The body of evidence for the efficacy of pharmacotherapy in AN was unsatisfactory, the quality of observations was questionable (eg, the majority were not blinded), and sample size was often small. More trials are needed, while considering that nonresponse and nonremission are typical of patients with AN. PMID:26145463

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

    Lencer, R; Korn, D

    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. PMID:25903501

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

    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

    Gahl, Thomas; Hall-Wilton, Richard; Kolya, Scott; Koennecke, Mark; Rescic, Miha; Rod, Thomas H; Sutton, Iain; Trahern, Garry; Kirstein, Oliver

    2015-01-01

    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...

  3. 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.

    Patients with Korsakoff's syndrome show devastating amnesia and executive deficits. Consequently, the ability to perform instrumental activities such as making coffee is frequently diminished. It is currently unknown whether patients with Korsakoff's syndrome are able to (re)learn instrumental activities. A good candidate for an effective teaching technique in Korsakoff's syndrome is errorless learning as it is based on intact implicit memory functioning. Therefore, the aim of the current study was two-fold: to investigate whether patients with Korsakoff's syndrome are able to (re)learn instrumental activities, and to compare the effectiveness of errorless learning with trial and error learning in the acquisition and maintenance of an instrumental activity, namely using a washing machine to do the laundry. Whereas initial learning performance in the errorless learning condition was superior, both intervention techniques resulted in similar improvement over eight learning sessions. Moreover, performance in a different spatial layout showed a comparable improvement. Notably, in follow-up sessions starting after four weeks without practice, performance was still elevated in the errorless learning condition, but not in the trial and error condition. The current study demonstrates that (re)learning and maintenance of an instrumental activity is possible in patients with Korsakoff's syndrome. PMID:24047431

  5. Odds and ends in psychopharmacology from the past 10 years.

    Howland, Robert H

    2015-01-01

    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. PMID:25622272

  7. Expert systems technology applied to instrument operation and data acquisition of a triple quadrupole mass spectrometer (TQMS)

    This presentation covers the work done at Lawrence Livermore National Laboratory by some computer programmers and analytical chemists specializing in mass spectrometry to develop an expert system for real-time tuning and optimization of operations of a triple quadrupole mass spectrometer (TQMS). This capability is important to increase the sensitivity possible for selected compounds throughout the entire mass range of the instrument, rather than settling for the traditional normalized calibration which lowers sensitivity at both ends of the mass scale

  8. Development and implantation of a control and data acquisition program for the calibration of instruments for diagnostic radiology

    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. LabVIEWMR 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.

  12. Defensive burying in rodents: ethology, neurobiology and psychopharmacology.

    De Boer, Sietse F; Koolhaas, Jaap M

    2003-02-28

    Defensive burying refers to the typical rodent behavior of displacing bedding material with vigorous treading-like movements of their forepaws and shoveling movements of their heads directed towards a variety of noxious stimuli that pose a near and immediate threat, such as a wall-mounted electrified shock-prod. Since its introduction 25 years ago by Pinel and Treit [J. Comp. Physiol. Psychol. 92 (1978) 708], defensive (shock-prod) burying has been the focus of a considerable amount of research effort delineating the methodology/ethology, psychopharmacology and neurobiology of this robust and species-specific active avoidance or coping response. The present review gives a summary of this research with special reference to the behavioral (face and construct) and pharmacological (predictive) validity of the shock-prod burying test as an animal model for human anxiety. Emphasis is also placed on some recent modifications of the paradigm that may increase its utility and reliability as to individual differences in expressed emotional coping responses and sensitivity to pharmacological treatments. Overall, the behavioral and physiological responses displayed in the shock-prod paradigm are expressions of normal and functionally adaptive coping patterns and the extremes of either active (i.e., burying) or passive (i.e., freezing) forms of responding in this test cannot simply be regarded as inappropriate, maladaptive or pathological. For this reason, the shock-prod paradigm is not an animal model for anxiety disorder or for any other psychiatric disease, but instead possesses a high degree of face and construct validity for normal and functionally adaptive human fear and anxious apprehension. However, the apparent good pharmacological validation (predictive validity) of this test reinforces the view that normal and pathological anxiety involves, at least partly, common neurobiological substrates. Therefore, this paradigm is not only suitable for screening potential

  13. Back to the future of psychopharmacology: A perspective on animal models in drug discovery.

    Hendriksen, Hendrikus; Groenink, Lucianne

    2015-07-15

    Psychopharmacology has had some bad publicity lately. Frankly, there have been some major problems along the way in developing new effective drugs for psychiatric disorders. After a prolonged period of high investments but low success rates, big pharmaceutical companies seem to retract their activities in the psychopharmacology field. Yet, the burden of mental disorders is likely to keep on growing in the next decades. In this position paper, we focus on drug development for depression and anxiety disorders, to narrow the scope of the assay. We describe the current situation of the psychopharmacology field, and analyse some of the methods and paradigms that have brought us here, but which should perhaps change to bring us even further. In addition, some of the factors contributing to the current stagnation in psychopharmacology are discussed. Finally, we suggest a number of changes that could lead to a more rational strategy for central nervous system drug development and which may circumvent some of the pitfalls leading to "me too" approaches. Central to the suggested changes, is the notion that mental disorders do not lead to several symptoms, but a network of causally related symptoms convolutes into a mental disorder. We call upon academia to put these changes in the early phases of drug development into effect. PMID:25814259

  15. Development of intelligent instruments with embedded HTTP servers for control and data acquisition in a cryogenic setup—The hardware, firmware, and software implementation

    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

    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.

  8. Herbal medicine for depression, anxiety and insomnia: a review of psychopharmacology and clinical evidence.

    Sarris, Jerome; Panossian, Alexander; Schweitzer, Isaac; Stough, Con; Scholey, Andrew

    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.

  10. 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.

  12. State of the art psychopharmacological treatment options in seasonal affective disorder.

    Yildiz, Mesut; Batmaz, Sedat; Songur, Emrah; Oral, Esat Timuçin

    2016-03-01

    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.

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

    Laura Font

    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.

  14. The Psychopharmacology Algorithm Project at the Harvard South Shore Program: An Algorithm for Generalized Anxiety Disorder.

    Abejuela, Harmony Raylen; Osser, David N

    2016-01-01

    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.

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

    Hasler, F; Studerus, E; Lindner, K; Ludewig, S; Vollenweider, F X

    2009-11-01

    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.

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

    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. PMID:25188733

    2006-11-01

    The British Association for Psychopharmacology (BAP) coordinated a meeting of experts to review the evidence on the drug treatment for dementia. The level of evidence (types) was rated using a standard system: Types 1a and 1b (evidence from meta-analysis of randomised controlled trials or at least one controlled trial respectively); types 2a and 2b (one well-designed study or one other type of quasi experimental study respectively); type 3 (non-experimental descriptive studies); and type 4 (expert opinion). There is type 1a evidence for cholinesterase inhibitors (donepezil, rivastigmine and galantamine) for mild to moderate Alzheimer's disease; memantine for moderate to severe Alzheimer's disease; and for the use of bright light therapy and aromatherapy. There is type 1a evidence of no effect of anti inflammatory drugs or statins. There is conflicting evidence regarding oestrogens, with type 2a evidence of a protective effect of oestrogens but 1b evidence of a harmful effect. Type 1a evidence for any effect of B12 and folate will be forthcoming when current trials report. There is type 1b evidence for gingko biloba in producing a modest benefit of cognitive function; cholinesterase inhibitors for the treatment of people with Lewy body disease (particularly neuropsychiatric symptoms); cholinesterase inhibitors and memantine in treatment cognitive impairment associated with vascular dementia; and the effect of metal collating agents (although these should not be prescribed until more data on safety and efficacy are available). There is type 1b evidence to show that neither cholinesterase inhibitors nor vitamin E reduce the risk of developing Alzheimer's disease in people with mild cognitive impairment; and there is no evidence that there is any intervention that can prevent the onset of dementia. There is type 1b evidence for the beneficial effects of adding memantine to cholinesterase inhibitors, and type 2b evidence of positive switching outcomes from one

    1991-05-01

    The purpose of this study was to generate a grounded theory of early object rule acquisition. The grounded theory approach and computer coding were used to analyze videotaped samples of an infant's and a toddler's independent object play, which produced the categories descriptive of three primary types of object rules; rules of object properties, rules of object action, and rules of object affect. This occupational science theory offers potential for understanding the role of objects in human occupations, for development of instruments, and for applications in occupational therapy early intervention.

  8. [Review of psychopharmacological treatments in adolescents and adults with autistic disorders].

    Baghdadli, A; Gonnier, V; Aussilloux, C

    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

  9. Lights! Camera! Action Projects! Engaging Psychopharmacology Students in Service-based Action Projects Focusing on Student Alcohol Abuse.

    Kennedy, Susan

    2016-01-01

    Alcohol abuse continues to be an issue of major concern for the health and well-being of college students. Estimates are that over 80% of college students are involved in the campus "alcohol culture." Annually, close to 2000 students die in the United States due to alcohol-related accidents, with another 600,000 sustaining injury due to alcohol-related incidents (NIAAA, 2013). Students enrolled in a Psychopharmacology course engaged in action projects (community outreach) focused on alcohol abuse on our campus. Research has indicated that these types of projects can increase student engagement in course material and foster important skills, including working with peers and developing involvement in one's community. This paper describes the structure and requirements of five student outreach projects and the final projects designed by the students, summarizes the grading and assessment of the projects, and discusses the rewards and challenges of incorporating such projects into a course.

  10. Brain Functional Effects of Psychopharmacological Treatments in Schizophrenia: A Network-based Functional Perspective Beyond Neurotransmitter Systems.

    De Rossi, Pietro; Chiapponi, Chiara; Spalletta, Gianfranco

    2015-01-01

    Psychopharmacological treatments for schizophrenia have always been a matter of debate and a very important issue in public health given the chronic, relapsing and disabling nature of the disorder. A thorough understanding of the pros and cons of currently available pharmacological treatments for schizophrenia is critical to better capture the features of treatment-refractory clinical pictures and plan the developing of new treatment strategies. This review focuses on brain functional changes induced by antipsychotic drugs as assessed by modern functional neuroimaging techniques (i.e. fMRI, PET, SPECT, MRI spectroscopy). The most important papers on this topic are reviewed in order to draw an ideal map of the main functional changes occurring in the brain during antipsychotic treatment. This supports the hypothesis that a network-based perspective and a functional connectivity approach are needed to fill the currently existing gap of knowledge in the field of psychotropic drugs and their mechanisms of action beyond neurotransmitter systems.

  15. Advanced Data Acquisition Systems

    Perotti, J.

    2003-01-01

    Current and future requirements of the aerospace sensors and transducers field make it necessary for the design and development of new data acquisition devices and instrumentation systems. New designs are sought to incorporate self-health, self-calibrating, self-repair capabilities, allowing greater measurement reliability and extended calibration cycles. With the addition of power management schemes, state-of-the-art data acquisition systems allow data to be processed and presented to the users with increased efficiency and accuracy. The design architecture presented in this paper displays an innovative approach to data acquisition systems. The design incorporates: electronic health self-check, device/system self-calibration, electronics and function self-repair, failure detection and prediction, and power management (reduced power consumption). These requirements are driven by the aerospace industry need to reduce operations and maintenance costs, to accelerate processing time and to provide reliable hardware with minimum costs. The project's design architecture incorporates some commercially available components identified during the market research investigation like: Field Programmable Gate Arrays (FPGA) Programmable Analog Integrated Circuits (PAC IC) and Field Programmable Analog Arrays (FPAA); Digital Signal Processing (DSP) electronic/system control and investigation of specific characteristics found in technologies like: Electronic Component Mean Time Between Failure (MTBF); and Radiation Hardened Component Availability. There are three main sections discussed in the design architecture presented in this document. They are the following: (a) Analog Signal Module Section, (b) Digital Signal/Control Module Section and (c) Power Management Module Section. These sections are discussed in detail in the following pages. This approach to data acquisition systems has resulted in the assignment of patent rights to Kennedy Space Center under U.S. patent # 6

    2016-06-01

    The British Association for Psychopharmacology guidelines specify the scope and targets of treatment for bipolar disorder. The third version is based explicitly on the available evidence and presented, like previous Clinical Practice Guidelines, as recommendations to aid clinical decision making for practitioners: it may also serve as a source of information for patients and carers, and assist audit. The recommendations are presented together with a more detailed review of the corresponding evidence. A consensus meeting, involving experts in bipolar disorder and its treatment, reviewed key areas and considered the strength of evidence and clinical implications. The guidelines were drawn up after extensive feedback from these participants. The best evidence from randomized controlled trials and, where available, observational studies employing quasi-experimental designs was used to evaluate treatment options. The strength of recommendations has been described using the GRADE approach. The guidelines cover the diagnosis of bipolar disorder, clinical management, and strategies for the use of medicines in short-term treatment of episodes, relapse prevention and stopping treatment. The use of medication is integrated with a coherent approach to psychoeducation and behaviour change. PMID:26979387

    2006-01-01

    After analyzing and comparing the traditional automobile instrument, the onboard instrument based on virtual instrument technology is designed in this paper. The PC/104 computer was employed as the core processing unit of the onboard instrument, and the several intelligent data acquisition nodes are set and connected by the CAN bus, through which the nodes can communicate with the core processing unit. The information of the vehicle's working condition can be displayed synthetically by adopting virtual instrument technology. When the working condition goes beyond its limit, the system can emit an alarm, record and storage the abnormal condition automatically, and suggest how to deal with the abnormity urgently. The development background and design idea of onboard information system were elaborated in the paper. The software, the hardware architecture and the principle of onboard information system were introduced in detail.

  5. WRATS Integrated Data Acquisition System

    Piatak, David J.

    2008-01-01

    The Wing and Rotor Aeroelastic Test System (WRATS) data acquisition system (DAS) is a 64-channel data acquisition display and analysis system specifically designed for use with the WRATS 1/5-scale V-22 tiltrotor model of the Bell Osprey. It is the primary data acquisition system for experimental aeroelastic testing of the WRATS model for the purpose of characterizing the aeromechanical and aeroelastic stability of prototype tiltrotor configurations. The WRATS DAS was also used during aeroelastic testing of Bell Helicopter Textron s Quad-Tiltrotor (QTR) design concept, a test which received international attention. The LabVIEW-based design is portable and capable of powering and conditioning over 64 channels of dynamic data at sampling rates up to 1,000 Hz. The system includes a 60-second circular data archive, an integrated model swashplate excitation system, a moving block damping application for calculation of whirl flutter mode subcritical damping, a loads and safety monitor, a pilot-control console display, data analysis capabilities, and instrumentation calibration functions. Three networked computers running custom-designed LabVIEW software acquire data through National Instruments data acquisition hardware. The aeroelastic model (see figure) was tested with the DAS at two facilities at NASA Langley, the Transonic Dynamics Tunnel (TDT) and the Rotorcraft Hover Test Facility (RHTF). Because of the need for seamless transition between testing at these facilities, DAS is portable. The software is capable of harmonic analysis of periodic time history data, Fast Fourier Transform calculations, power spectral density calculations, and on-line calibration of test instrumentation. DAS has a circular buffer archive to ensure critical data is not lost in event of model failure/incident, as well as a sample-and-hold capability for phase-correct time history data.

    2016-01-01

    Background: The characterization of the first episode of psychosis and how it should be treated are principal issues in actual research. Realistic, naturalistic studies are necessary to represent the entire population of first episode of psychosis attended in daily practice. Methods: Sixteen participating centers from the PEPs project recruited 335 first episode of psychosis patients, aged 7 to 35 years. This article describes and discusses the psychopharmacological interventions and safety profiles at baseline and during a 60-day pharmacovigilance period. Results: The majority of first episode of psychosis patients received a second-generation antipsychotic (96.3%), orally (95%), and in adjusted doses according to the product specifications (87.2%). A total of 24% were receiving an antipsychotic polytherapy pattern at baseline, frequently associated with lower or higher doses of antipsychotics than the recommended ones. Eight patients were taking clozapine, all in monotherapy. Males received higher doses of antipsychotic (P=.043). A total of 5.2% of the patients were being treated with long-acting injectable antipsychotics; 12.2% of the patients received anticholinergic drugs, 12.2% antidepressants, and 13.7% mood stabilizers, while almost 40% received benzodiazepines; and 35.52% reported at least one adverse drug reaction during the pharmacovigilance period, more frequently associated with higher antipsychotic doses and antipsychotic polytherapy (85.2% vs 45.5%, P<.001). Conclusions: These data indicate that the overall pharmacologic prescription for treating a first episode of psychosis in Spain follows the clinical practice guideline recommendations, and, together with security issues, support future research of determinate pharmacological strategies for the treatment of early phases of psychosis, such as the role of clozapine, long-acting injectable antipsychotics, antipsychotic combination, and the use of benzodiazepines.

  14. Development and implantation of a control and data acquisition program for the calibration of instruments for diagnostic radiology; Desenvolvimento e implantacao de um programa de controle e aquisicao de dados na calibracao de instrumentos em radiodiagnostico

    Betti, Flavio

    2007-07-01

    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.

  15. On Shaft Data Acquisition System (OSDAS)

    Pedings, Marc; DeHart, Shawn; Formby, Jason; Naumann, Charles

    2012-01-01

    On Shaft Data Acquisition System (OSDAS) is a rugged, compact, multiple-channel data acquisition computer system that is designed to record data from instrumentation while operating under extreme rotational centrifugal or gravitational acceleration forces. This system, which was developed for the Heritage Fuel Air Turbine Test (HFATT) program, addresses the problem of recording multiple channels of high-sample-rate data on most any rotating test article by mounting the entire acquisition computer onboard with the turbine test article. With the limited availability of slip ring wires for power and communication, OSDAS utilizes its own resources to provide independent power and amplification for each instrument. Since OSDAS utilizes standard PC technology as well as shared code interfaces with the next-generation, real-time health monitoring system (SPARTAA Scalable Parallel Architecture for Real Time Analysis and Acquisition), this system could be expanded beyond its current capabilities, such as providing advanced health monitoring capabilities for the test article. High-conductor-count slip rings are expensive to purchase and maintain, yet only provide a limited number of conductors for routing instrumentation off the article and to a stationary data acquisition system. In addition to being limited to a small number of instruments, slip rings are prone to wear quickly, and introduce noise and other undesirable characteristics to the signal data. This led to the development of a system capable of recording high-density instrumentation, at high sample rates, on the test article itself, all while under extreme rotational stress. OSDAS is a fully functional PC-based system with 48 channels of 24-bit, high-sample-rate input channels, phase synchronized, with an onboard storage capacity of over 1/2-terabyte of solid-state storage. This recording system takes a novel approach to the problem of recording multiple channels of instrumentation, integrated with the test

    2004-08-01

    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.

  3. Seismic instrumentation

    For better understanding of the specification for seismic instrumentation of a nuclear power plant, the lecture gives some fundamental remarks to the seismic risk in the Federal Republic of Germany and to the data characterizing an earthquake event. Coming from the geophysical properties of an earthquake, the quantities are explained which are used in the design process of nuclear power plants. This process is shortly described in order to find the requirements for the specification of the seismic instrumentation. In addition the demands of licensing authorities are given. As an example the seismic instrumentation of KKP-1, BWR, is shown. The paper deals with kind and number of instruments, their location in the plant and their sensitivity and calibration. Final considerations deal with the evaluation of measured data and with plant operation after an earthquake. Some experience concerning the earthquake behaviour of equipment not designed to withstand earthquake loads is mentioned. This experience has initiated studies directed to quantification of the degree of conservatism of the assumptions in the seismic design of nuclear power plants. A final garget of these studies are more realistic design rules. (RW)

  4. RHIC instrumentation

    The Relativistic Heavy Ion Collider (RHIC) consists of two 3.8 km circumference rings utilizing 396 superconducting dipoles and 492 superconducting quadrupoles. Each ring will accelerate approximately 60 bunches of 1011 protons to 250 GeV, or 109 fully stripped gold ions to 100 GeV/nucleon. Commissioning is scheduled for early 1999 with detectors for some of the 6 intersection regions scheduled for initial operation later in the year. The injection line instrumentation includes: 52 beam position monitor (BPM) channels, 56 beam loss monitor (BLM) channels, 5 fast integrating current transformers and 12 video beam profile monitors. The collider ring instrumentation includes: 667 BPM channels, 400 BLM channels, wall current monitors, DC current transformers, ionization profile monitors (IPMs), transverse feedback systems, and resonant Schottky monitors. The use of superconducting magnets affected the beam instrumentation design. The BPM electrodes must function in a cryogenic environment and the BLM system must prevent magnet quenches from either fast or slow losses with widely different rates. RHIC is the first superconducting accelerator to cross transition, requiring close monitoring of beam parameters at this time. High space-charge due to the fully stripped gold ions required the IPM to collect magnetically guided electrons rather than the conventional ions. Since polarized beams will also be accelerated in RHIC, additional constraints were put on the instrumentation. The orbit must be well controlled to minimize depolarizing resonance strengths. Also, the position monitors must accommodate large orbit displacements within the Siberian snakes and spin rotators. The design of the instrumentation will be presented along with results obtained during bench tests, the injection line commissioning, and the first sextant test. copyright 1998 American Institute of Physics

  7. Future data acquisition at ISIS

    Data collection techniques at ISIS are fast reaching the point where the current computer systems will no longer be able to migrate the data to long-term storage, let alone enable their analysis at a speed compatible with continuous use of the ISIS instruments. The current data acquisition electronics (DAE 1) and migration path work effectively but have a number of inherent difficulties: (1) Seven instruments are equipped with VAX computers as their Front End Minicomputers (FEM). Unfortunately these machines usually possess insufficient processor power to perform some of the more complex data reduction. This means that the raw data have necessarily to be networked to the HUB computer before analysis. (2) The size of bulk store memory is restricted to 16 Mbytes by the 24 bit address field of Multibus. (3) The DAE error detection and analysis system of FEM is crude. It is clear that the most effective method to improve on this situation is to reduce the data volume flowing between the DAE and the FEM and to provide facilities to monitor data acquisition within the DAE. For these purposes processing power must be incorporated closer to the point of data collection. It has been decided to implement processing elements within DAE 2 (the next generation of DAE) in the form of intelligent memory boards. 6 figs., 1 tab

  9. Serendipity and psychopharmacology.

    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.

    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.

    Teleology descriptions capture the purpose of an entity, mechanism, or activity with which they are associated. These descriptions can be used in explanation, diagnosis, and design reuse. We describe a technique for acquiring teleological descriptions expressed in the teleology language TeD. Acquisition occurs during design by observing design modifications and design verification. We demonstrate the acquisition technique in an electronic circuit design.

  18. Data acquisition system

    The topic of this paper deals with a multi parametric acquisition system developed around a four input Analog to Digital Converter working in CAMAC Standard. The acquisition software is built in MS Visual C++ on a standard PC with a USB interface. It has a visual interface which permits Start/Stop of the acquisition, setting the type of acquisition (True/Live time), the time and various menus for primary data acquisition. The spectrum is dynamically visualized with a moving cursor indicating the content and position. The microcontroller PIC16C765 is used for data transfer from ADC to PC; The microcontroller and the software create an embedded system which emulates the CAMAC protocol programming, the 4 input ADC for operating modes ('zero suppression', 'addressed' and 'sequential') and handling the data transfers from ADC to its internal memory. From its memory the data is transferred into the PC by the USB interface. The work is in progress. (authors)

    1997-09-01

    The control and data acquisition systems for Atlas will use a large degree of decentralization. By distributing control points close to the systems being controlled, the authors expect to simplify the task of isolating electronic systems from the large expected EMI pulses, allow connection of the various parts of the system by high-level fiber-optic networks, allow a simple configuration of the control and data acquisition screen rooms, and simplify the software efforts through the resulting modularization. The Atlas control system must control capacitor charging, machine and diagnostic timing and triggering, marx module diagnostics, vacuum systems, gas handling for railgaps, safety interlocks, and oil handling. Many of these tasks will be performed by industrial-style programmable logic controllers (PLCs). Each of 38 Marx bank maintenance units will have a control and diagnostic package which will monitor both charging and discharging current and railgap trigger timing. An unusual feature of digitizers to record each Marx module`s output waveform, plus nanosecond resolution time interval meters to record the firing time of each railgap. The machine data acquisition system for Atlas will be built around an SQL database, use National Instruments LabVIEW software to control data acquisition instruments and provide links for a variety of experimentalists` data analysis packages. World Wide Web access will provide an interface through which users can monitor experimental data and machine status.

  1. The NIFFTE Data Acquisition System

    Qu, Hai; Niffte Collaboration

    2011-10-01

    The Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) will employ a novel, high granularity, pressurized Time Projection Chamber to measure fission cross-sections of the major actinides to high precision over a wide incident neutron energy range. These results will improve nuclear data accuracy and benefit the fuel cycle in the future. The NIFFTE data acquisition system (DAQ) has been designed and implemented on the prototype TPC. Lessons learned from engineering runs have been incorporated into some design changes that are being implemented before the next run cycle. A fully instrumented sextant of EtherDAQ cards (16 sectors, 496 channels) will be used for the next run cycle. The Maximum Integrated Data Acquisition System (MIDAS) has been chosen and customized to configure and run the experiment. It also meets the requirement for remote control and monitoring of the system. The integration of the MIDAS online database with the persistent PostgreSQL database has been implemented for experiment usage. The detailed design and current status of the DAQ system will be presented.

  2. Web-based data acquisition

    胡旭东; 俞红; 陈鹰

    2002-01-01

    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.

    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) μCi Am-241 and (110 ± 50) μCi of Np-237. (author)

    Problems of development of control system for laboratory instruments are discussed. Requirements for automation of instrumentation are considered, which can be devided in three great classes of tasks: instrument functional control, data acquisition and storage, data processing and result display. Advantages and disadvantages of computers (maxi-computers mini-computers and microprocessors) are compared which were used for automation of laboratory instruments. Microprocessor advantages (low cost, design flexibility, reliability) allow to solve successfully the instrumentation automation problem. The advent of the microprocessor induces a new thinking philosophy based on distributed intelligence and functional specialization, associated to network organization

  15. Plans for the CIT Instrumentation and Control System

    Extensive experience with previous fusion experiments (TFTR, MFTF-B and others) is driving the design of the Instrumentation and Control System (I ampersand C) for the Compact Ignition Tokamak (CIT) to be built at Princeton. The new design will reuse much equipment from TFTR and will be subdivided into six major parts: machine control, machine data acquisition, plasma diagnostic instrument control and instrument data acquisition, the database, shot sequencing and safety interlocks. In a major departure from previous fusion experiment control systems, the CIT machine control system will be a commercial process control system. Since the machine control system will be purchased as a completely functional product, the authors will be able to concentrate development manpower in plasma diagnostic instrument control, data acquisition, data processing and analysis, and database systems. They will discuss the issues driving the design, give a design overview and state the requirements upon any prospective commercial process control system

    Henningsson, Stefan; Yetton, Philip

    2013-01-01

    The extant research on post-acquisition IT integration analyzes how acquirers realize IT-based value in individual acquisitions. However, serial acquirers make 60% of acquisitions. These acquisitions are not isolated events, but are components in growth-by-acquisition programs. To explain how...... serial acquirers realize IT-based value, we develop three propositions on the sequential effects on post-acquisition IT integration in acquisition programs. Their combined explanation is that serial acquirers must have a growth-by-acquisition strategy that includes the capability to improve IT...... integration capabilities, to sustain high alignment across acquisitions and to maintain a scalable IT infrastructure with a flat or decreasing cost structure. We begin the process of validating the three propositions by investigating a longitudinal case study of a growth-by-acquisition program....

  20. VERITAS Data Acquisition

    Hays, E

    2007-01-01

    VERITAS employs a multi-stage data acquisition chain that extends from the VME readout of custom 500 MS/s 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.

    2015-10-01

    Neutron energy measurements can be achieved using time-of-flight (ToF) techniques. A digital data acquisition system was developed for reliable ToF measurements with subnanosecond timing resolution based on digitizers with 10 ns and 4 ns sampling periods using pulse shape analysis algorithms. A validation procedure was developed to confirm the reliability. The response of the algorithm to photomultiplier signals was studied using a specially designed experimental system based on fast plastic scintillators. The presented developments enabled digital data acquisition systems to instrument the recently developed Versatile Array of Neutron Detectors at Low-Energy (VANDLE). This research was sponsored in part by the National Nuclear Security Administration under the Stewardship Science Academic Alliances program through DOE Cooperative Agreement No. DE-FG52-08NA28552 and the Office of Nuclear Physics.

  9. Amplitudes, acquisition and imaging

    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.

  10. Unsupervised Language Acquisition

    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...

  11. Implementing acquisition strategies

    The objective of this paper is to address some of the strategies necessary to effect a successful asset or corporate acquisition. Understanding the corporate objective, the full potential of the asset, the specific strategies to be employed, the value of time, and most importantly the interaction of all these are crucial, for missed steps are likely to result in missed opportunities. The amount of factual information that can be obtained and utilized in a timely fashion is the largest single hurdle to the capture of value in the asset or corporate acquisition. Fact, familiarity and experience are key in this context. The importance of the due diligence process prior to title or data transfer cannot be overemphasized. Some of the most important assets acquired in a merger may be the people. To maximize effectiveness, it is essential to merge both existing staff and those that came with the new acquisition as soon as possible. By thinking together as a unit, knowledge and experience can be applied to realize the potential of the asset. Hence team building is one of the challenges, doing it quickly is usually the most effective. Developing new directions for the new enlarged company by combining the strengths of the old and the new creates more value, as well as a more efficient operation. Equally important to maximizing the potential of the new acquisition is the maintenance of the momentum generated by the need to grow that gave the impetus to acquiring new assets in the first place. In brief, the right mix of vision, facts and perceptions, quick enactment of the post-close strategies and keeping the momentum alive, are the principal ingredients of a focused strategy

  14. MDSplus data acquisition system

    MDSplus, a tree based, distributed data acquisition system, was developed in collaboration with the ZTH Group at Los Alamos National Lab and the RFX Group at CNR in Padua, Italy. It is currently in use at MIT, RFX in Padua, TCV at EPFL in Lausanne, and KBSI in South Korea. MDSplus is made up of a set of X/motif based tools for data acquisition and display, as well as diagnostic configuration and management. It is based on a hierarchical experiment description which completely describes the data acquisition and analysis tasks and contains the results from these operations. These tools were designed to operate in a distributed, client/server environment with multiple concurrent readers and writers to the data store. While usually used over a Local Area Network, these tools can be used over the Internet to provide access for remote diagnosticians and even machine operators. An interface to a relational database is provided for storage and management of processed data. IDL is used as the primary data analysis and visualization tool.

    2010-07-01

    In this paper we describe the data acquisition and control system of the Dark Energy Camera (DECam), which will be the primary instrument used in the Dark Energy Survey (DES). DES is a high precision multibandpath wide area survey of 5000 square degrees of the southern sky. DECam currently under construction at Fermilab will be a 3 square degree mosaic camera mounted at the prime focus of the Blanco 4m telescope at the Cerro-Tololo International Observatory (CTIO). The DECam data acquisition system (SISPI) is implemented as a distributed multi-processor system with a software architecture built on the Client-Server and Publish-Subscribe design patterns. The underlying message passing protocol is based on PYRO, a powerful distributed object technology system written entirely in Python. A distributed shared variable system was added to support exchange of telemetry data and other information between different components of the system. In this paper we discuss the SISPI infrastructure software, the image pipeline, the observer interface and quality monitoring system, and the instrument control system.

  4. Multifold borehole radar acquisition and processing

    The multifold acquisition principle was applied to a borehole radar survey, performed in a granitic site (Grimsel Test Site, Switzerland). Two multifold coverage acquisitions (40-fold and 20-fold) were carried out in a subhorizontal borehole. Instrumental drifts (transmission time and sampling frequency fluctuations) were corrected in order to remove shifts observed on CMP gathers and to optimize velocity analysis and trace stacking. Computation of velocity spectra was adapted in order to take into account the features of the medium investigated (homogeneous velocity, various reflector orientations). The NMO velocities were then interpreted as angles between reflectors and the survey line. The processing, based on the computation of several constant velocity stacked sections performed with different NMO velocities, leads to better results than the standard DMO + NMO processing. The signal-to-noise ratio of the stacked profile is improved in comparison with the single-fold section, which results from a standard acquisition. From a practical pint of view, the implementation of a multifold radar survey within a borehole is difficult but a greater investigation range is obtained, more reflectors are detected and the mapping of geological discontinuities is improved

  10. Implementation of High Speed Distributed Data Acquisition System

    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

  11. Development of an optical beam system for deep sea data acquisition

    Remotely Operated Vehicles (ROV) are an ideal method for acquiring data from instruments located on the seabed. Electrical, acoustic or optical signals can be used to communicate with the data acquisition system. While optical signals have high capacity, the power of the optical beam decreases rapidly with distance in sea water; however, the ROV's ability to approach the instruments eliminates this problem. To investigate a feasibility of an optical beam system for underwater data acquisition, the author has developed and manufactured a prototype data acquisition instrument which the ROV can control. Based on the communication test results, he concludes that such a system is a practical means of short-range underwater data acquisition

  12. Portable data acquisition system

    Lawrence Livermore National Laboratory (LLNL) has developed a Portable Data Acquisition (DAQ) System that is basically a laboratory-scale of Program Logic Control (PLC). This DAQ system can obtain signals from numerous sensors (e.g., pH, level, pressure, flow meters), open and close valves, and turn on and off pumps. The data can then be saved on a spreadsheet or displayed as a graph/indicator in real-time on a computer screen. The whole DAQ system was designed to be portable so that it could sit on a bench top during laboratory-scale treatability studies, or moved out into the field during larger studies. This DAQ system is also fairly simple to use. All that is required is some working knowledge of LabVIEW 4.1, and how to properly wire the process equipment. The DAQ system has been used during treatability studies on cesium precipitation, controlled hydrolysis of water- reactive wastes, and other waste treatment studies that enable LLNL to comply with the Federal Facility Compliance Act (FFCAct). Improved data acquisition allows the study to be better monitored, and therefore better controlled, and can be used to determine the results of the treatment study more effectively. This also contributes to the design of larger treatment processes

  13. Aircraft Data Acquisition

    Elena BALMUS

    2016-03-01

    Full Text Available The introduction of digital systems instead of analog ones has created a major separation in the aviation technology. Although the digital equipment made possible that the increasingly faster controllers take over, we should say that the real world remains essentially analogue [4]. Fly-by-wire designers attempting to control and measure the real feedback of an aircraft were forced to find a way to connect the analogue environment to their digital equipment. In order to manage the implications of this division in aviation, data optimization and comparison has been quite an important task. The interest in using data acquisition boards is being driven by the technology and design standards in the new generation of aircraft and the ongoing efforts of reducing weight and, in some cases addressing the safety risks. This paper presents a sum of technical report data from post processing and diversification of data acquisition from Arinc 429 interface on a research aircraft platform. Arinc 429 is by far the most common data bus in use on civil transport aircraft, regional jets and executive business jets today. Since its introduction on the Boeing 757/767 and Airbus aircraft in the early 1980s hardly any aircraft has been produced without the use of this data bus. It was used widely by the air transport indu

  17. Assessment of the Knowledge Acquisition Process in Lithuanian Insurance Sector

    Jurgita Raudeliūnienė

    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 efficient use of complex neutron scattering instruments is often hindered by the complex nature of their operating software. This complexity exists at each experimental step: data acquisition, reduction and analysis, with each step being as important as the previous. For example, whilst command line interfaces are powerful at automated acquisition they often reduce accessibility by novice users and sometimes reduce the efficiency for advanced users. One solution to this is the development of a graphical user interface which allows the user to operate the instrument by a simple and intuitive "push button" approach. This approach was taken by the Motofit software package for analysis of multiple contrast reflectometry data. Here we describe the extension of this package to cover the data acquisition and reduction steps for the Platypus time-of-flight neutron reflectometer. Consequently, the complete operation of an instrument is integrated into a single, easy to use, program, leading to efficient instrument usage.

  2. Electronics and data acquisition

    High energy physics detectors span a wide range of applications with greatly differing requirements. Although the detector configurations are very different, the application of only a few basic signal acquisition principles is required. The LHC required novel designs, but built on a wide range of previous developments that had been completed for other experiments. The high luminosity drove up the event rates, but multiple interactions per bunch crossing also made occupancy a major challenge. The large scale of detector subsystems imposed efficient designs where cost was a major consideration, but the difficulty of accessing detector components added reliability to the list of more severe requirements. Radiation damage, especially in the inner detectors, added additional crucial constraints. This paper will discuss electronics requirements, the configurations of major LHC detectors, and the readout systems. After a discussion of front-end implementations and radiation effects, systems with extreme performance requirements are described in more detail, i.e. silicon strip and pixel systems.

  3. Plasmid acquisition in microgravity

    Juergensmeyer, Margaret A.; Juergensmeyer, Elizabeth A.; Guikema, James A.

    1995-01-01

    In microgravity, bacteria often show an increased resistance to antibiotics. Bacteria can develop resistance to an antibiotic after transformation, the acquisition of DNA, usually in the form of a plasmid containing a gene for resistance to one or more antibiotics. In order to study the capacity of bacteria to become resistant to antibiotics in microgravity, we have modified the standard protocol for transformation of Escherichia coli for use in the NASA-flight-certified hardware package, The Fluid Processing Apparatus (FPA). Here we report on the ability of E. coli to remain competent for long periods of time at temperatures that are readily available on the Space Shuttle, and present some preliminary flight results.

  4. Language Acquisition in Computers

    Belzner, Megan; Roman, Jorge H

    2012-01-01

    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...

  5. Instrumentation a reader

    Pope, P

    1990-01-01

    This book contains a selection of papers and articles in instrumentation previously pub­ lished in technical periodicals and journals of learned societies. Our selection has been made to illustrate aspects of current practice and applications of instrumentation. The book does not attempt to be encyclopaedic in its coverage of the subject, but to provide some examples of general transduction techniques, of the sensing of particular measurands, of components of instrumentation systems and of instrumentation practice in two very different environments, the food industry and the nuclear power industry. We have made the selection particularly to provide papers appropriate to the study of the Open University course T292 Instrumentation. The papers have been chosen so that the book covers a wide spectrum of instrumentation techniques. Because of this, the book should be of value not only to students of instrumen­ tation, but also to practising engineers and scientists wishing to glean ideas from areas of instrumen...

  7. PERFORMANCE CONFIRMATION IN-SITU INSTRUMENTATION

    N.T. Raczka

    2000-05-23

    The purpose of this document is to identify and analyze the types of in-situ instruments and methods that could be used in support of the data acquisition portion of the Performance Confirmation (PC) program at the potential nuclear waste repository at Yucca Mountain. The PC program will require geomechanical , geophysical, thermal, and hydrologic instrumentation of several kinds. This analysis is being prepared to document the technical issues associated with each type of measurement during the PC period. This analysis utilizes the ''Performance Confirmation Input Criteria'' (CRWMS M&O 1999a) as its starting point. The scope of this analysis is primarily on the period after the start of waste package emplacement and before permanent closure of the repository, a period lasting between 15 and 300 years after last package emplacement (Stroupe 2000, Attachment 1, p. 1). The primary objectives of this analysis are to: (1) Review the design criteria as presented in the ''Performance Confirmation Input Criteria'' (CRWMS M&O 1999a). The scope of this analysis will be limited to the instrumentation related to parameters that require continuous monitoring of the conditions underground. (2) Preliminary identification and listing of the data requirements and parameters as related to the current repository layout in support of PC monitoring. (3) Preliminary identification of methods and instrumentation for the acquisition of the required data. Although the ''Performance Confirmation Input Criteria'' (CRWMS M&O 1999a) defines a broad range of data that must be obtained from a variety of methods, the focus of this analysis is on instrumentation related to the performance of the rock mass and the formation of water in the repository environment, that is obtainable from in-situ observation, testing, and monitoring.

  9. Satellite oceanography - The instruments

    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.

    1996-06-01

    Westinghouse Hanford Company Project W-211 is responsible for providing the system capabilities to remove radioactive waste from ten double-shell tanks used to store radioactive wastes on the Hanford Site in Richland, Washington. The project is also responsible for measuring tank waste slurry properties prior to injection into pipeline systems, including the Replacement of Cross-Site Transfer System. This report summarizes studies of the appropriateness of the instrumentation specified for use in Project W-211. The instruments were evaluated in a test loop with simulated slurries that covered the range of properties specified in the functional design criteria. The results of the study indicate that the compact nature of the baseline Project W-211 loop does not result in reduced instrumental accuracy resulting from poor flow profile development. Of the baseline instrumentation, the Micromotion densimeter, the Moore Industries thermocouple, the Fischer and Porter magnetic flow meter, and the Red Valve Pressure transducer meet the desired instrumental accuracy. An alternate magnetic flow meter (Yokagawa) gave nearly identical results as the baseline fischer and Porter. The Micromotion flow meter did not meet the desired instrument accuracy but could potentially be calibrated so that it would meet the criteria. The Nametre on-line viscometer did not meet the desired instrumental accuracy and is not recommended as a quantitative instrument although it does provide qualitative information. The recommended minimum set of instrumentation necessary to ensure the slurry meets the Project W-058 acceptance criteria is the Micromotion mass flow meter and delta pressure cells.

    Allen, Carlton; Sellar, Glenn; Nunez, Jorge I.; Winterhalter, Daniel; Farmer, Jack

    2010-01-01

    Astronauts on long-duration lunar missions will need the capability to "high-grade" their samples - to select the highest value samples for transport to Earth - and to leave others on the Moon. Instruments that may be useful for such high-grading are under development. Instruments are also being developed for possible use on future lunar robotic landers, for lunar field work, and for more sophisticated analyses at a lunar outpost. The Johnson Space Center Astromaterials acquisition and Curation Office (JSC Curation) wll support such instrument testing by providing lunar sample "ground truth".

This year almost fifty students took part in the School. “Leading experts in the field gave lectures ...

  16. Automated Fringe Pattern Acquisition for Portable Laser Shearography

    In shearography system one of the most important tasks is the automatic, fast, reliable processing of the fringe patterns to allow real time inspection. Development of digital CCD cameras, the PC (fast and small data acquisition), high power lasers have led to dramatic performance improvements in shearography instruments and systems. This paper concentrates on development of fringe pattern acquisition using digital CCD camera for portable laser shearography system. A new program for fringe pattern processing which incorporates rapid methods for automatic fringe pattern acquisition and filtering has been developed. The algorithm is written using MATLAB. A graphical user interface with several functions was developed to ensure an easy adaptation in custom applications and providing a flexible way for additional functions. The preliminary results show that the developed algorithm can be used to generate good contrast and reliable fringe pattern. (author)

  1. Wideband Signal Acquisition via Frequency-Interleaved Sampling

    Callender, Steven William

    2015-01-01

    High-speed analog-to-digital converters (ADCs) are key enabling blocks for emerging wideband applications in communication, high-end instrumentation, and medical imaging. Larger signaling bandwidth improves system performance and necessitates high-speed ADCs for accurate digitization. As an example, current state-of-the-art oscilloscopes have an acquisition bandwidth exceeding 60GHz with effective sample rates greater than 100GS/s. This places significant difficulty in the design of sample-a...

  3. 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.

  4. DATA ACQUISITION (DAQ)

    Gerry Bauer

    The CMS Storage Manager System The tail-end of the CMS Data Acquisition System is the Storage Manger (SM), which collects output from the HLT and stages the data at Cessy for transfer to its ultimate home in the Tier-0 center. A SM system has been used by CMS for several years with the steadily evolving software within the XDAQ framework, but until relatively recently, only with provisional hardware. The SM is well known to much of the collaboration through the ‘MiniDAQ’ system, which served as the central DAQ system in 2007, and lives on in 2008 for dedicated sub-detector commissioning. Since March of 2008 a first phase of the final hardware was commissioned and used in CMS Global Runs. The system originally planned for 2008 aimed at recording ~1MB events at a few hundred Hz. The building blocks to achieve this are based on Nexsan's SATABeast storage array - a device  housing up to 40 disks of 1TB each, and possessing two controllers each capable of almost 200 MB/sec throughput....

  10. Options for Next Generation Digital Acquisition Systems

    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.

  11. Robotic data acquisition of directional reflectance factors

    A data collection platform for rapid and repeatable positioning of a down-looking radiometer was constructed using commercially available instrumentation and hardware. The platform also accommodated a second radiometer to measure irradiance at the same instant the other radiometer measured target radiance. Stepper motors position the down-looking radiometer at programmed view zenith and view azimuth angles. A Polycorder and stepper motor interface control the stepper motors while data acquisition is the sole responsibility of the Polycorder. Less than 15 min is required to measure target radiance from a full set of measurements consisting of 182 combinations of view zenith and view azimuth angles. Positioning accuracy of the viewing radiometer is within ± 0.2° for a nominal 15° angular movement. The system has proven to be dependable, easy to use, highly mobile, and adaptable. (author)

  17. Automated ship image acquisition

    Hammond, T. R.

    2008-04-01

    The experimental Automated Ship Image Acquisition System (ASIA) collects high-resolution ship photographs at a shore-based laboratory, with minimal human intervention. The system uses Automatic Identification System (AIS) data to direct a high-resolution SLR digital camera to ship targets and to identify the ships in the resulting photographs. The photo database is then searchable using the rich data fields from AIS, which include the name, type, call sign and various vessel identification numbers. The high-resolution images from ASIA are intended to provide information that can corroborate AIS reports (e.g., extract identification from the name on the hull) or provide information that has been omitted from the AIS reports (e.g., missing or incorrect hull dimensions, cargo, etc). Once assembled into a searchable image database, the images can be used for a wide variety of marine safety and security applications. This paper documents the author's experience with the practicality of composing photographs based on AIS reports alone, describing a number of ways in which this can go wrong, from errors in the AIS reports, to fixed and mobile obstructions and multiple ships in the shot. The frequency with which various errors occurred in automatically-composed photographs collected in Halifax harbour in winter time were determined by manual examination of the images. 45% of the images examined were considered of a quality sufficient to read identification markings, numbers and text off the entire ship. One of the main technical challenges for ASIA lies in automatically differentiating good and bad photographs, so that few bad ones would be shown to human users. Initial attempts at automatic photo rating showed 75% agreement with manual assessments.

  3. Medical instruments in museums

    Söderqvist, Thomas; Arnold, Ken

    2011-01-01

    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....

    2014-10-01

    Full Text Available Surgical instruments are the group of tools used in surgical procedures. They are very expensive and sophisticated. Consequently, a standardized and meticulous care is essential; they should go through the decontamination, cleaning and sterilization process. These instruments are designed in order to provide surgeons with tools that help them to perform a basic surgical procedure; there are multiple variations and the design depends on their function. This paper aims at showing all surgical instruments that can be used in an operating room during surgery and are not generally included in the medical literature.

  7. Mass spectrometers: instrumentation

    Cooks, R. G.; Hoke, S. H., II; Morand, K. L.; Lammert, S. A.

    1992-09-01

    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

  16. Electronic instrumentation for smart structures

    Blanar, George J.

    1995-04-01

    The requirements of electronic instrumentation for smart structures are similar to those of data acquisition systems at our national particle physics laboratories. Modern high energy and heavy ion physics experiments may have tens of thousands of channels of data sources producing data that must be converted to digital form, compacted, stored and interpreted. In parallel, multiple sensors distributed in and around smart structures generate either binary or analog signals that are voltage, charge, or time like in their information content. In all cases, they must be transmitted, converted and preserved into a unified digital format for real-time processing. This paper will review the current status of practical large scale electronic measurement systems with special attention to architectures and physical organization. Brief surveys of the current state of the art will include preamplifiers and amplifiers, comparators and discriminators, voltage or charge analog-to-digital converters, time internal meters or time-to-digital converters, and finally, counting or scalar systems. The paper will conclude by integrating all of these ideas in a concept for an all-digital readout of a smart structure using the latest techniques used in physics research today.

    Nagai, T; Sleege, G; Petry, D

    2007-01-01

    VERITAS is a new atmospheric Cherenkov imaging telescope array to detect very high energy gamma rays above 100 GeV. The array is located in southern Arizona, USA, at an altitude of 1268m above sea level. The array consists of four 12-m telescopes of Davies-Cotton design and structurally resembling the Whipple 10-m telescope. The four focal plane instruments are equipped with high-resolution (499 pixels) fast photo-multiplier-tube (PMT) cameras covering a 3.5 degree field of view with 0.15 degree pixel separation. Light concentrators reduce the dead-space between PMTs to 25% and shield the PMTs from ambient light. The PMTs are connected to high-speed preamplifiers allowing operation at modest anode current and giving good single photoelectron peaks in situ. Electronics in the focus box provides real-time monitoring of the anode currents for each pixel and ambient environmental conditions. A charge injection subsystem installed in the focus box allows daytime testing of the trigger and data acquisition system b...

    2015-11-01

    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.

  9. Dam Safety Instrumentation

    P. R. Bamane

    2014-06-01

    Full Text Available In most of the cases, the materials are tested in laboratories and designs are based on assumptions that the same results will be met with, during actual construction. As there are always large variations in materials, their properties, construction methods and their control, the actual product defers from the original assumptions. In this paper, instruments required to check the behaviour and stability of dams are discussed with their necessity, use and operation. These instruments prove to be much useful in proper maintenance of dam, and hence they should be installed under the guidance of experts at appropriate places in the dam. A conclusion has been arrived that there should be close co-operation between the designers, instrumentation specialist, expert analysis and site authorities to achieve the goal of instrumentation.

  16. Modeling of Musical Instruments

    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.

  17. Autonomous Surface Sample Acquisition for Planetary and Lunar Exploration

    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

  18. Water level instrumentation simulation

    Through simulation, evaluations of system performance can be made to increase efficiency, reduce costs, enhance safety and provide effective training. A full function simulation for evaluating water level measurement requires modeling the physical process, the process instrumentation response and where appropriate, the human input/response. This paper examines a full function application simulating the primary system water level in a Boiling Water Reactor (BWR). The physical processes associated with BWR vessel level response are modeled with the Modular Accident Analysis Program (MAAP). The MAAP code is used as the basis for providing primary system and containment thermal-hydraulic response to a compendium of expected plant transients. The BWR vessel level instruments is modeled with the FAI developed Instrumentation PACkage (IPAC). With the thermal-hydraulic input from MAAP, the IPAC software models the various phenomena associated with water level measurements including the effects due to: (1) instrument channel calibration, (2) instrument drift and (3) containment (drywell) environmental effects. This paper discusses the IPAC models (instrumentation components) along with the factors which influence the mass balance of water in the downcomer region. A comparison of the BWR vessel water level complete simulation package to data from a simulated BWR plant transient culminates the discussion of this paper. The full function simulation package presented in this paper, enables a software-based representation of the BWR vessel level to be evaluated under various hypothetical plant conditions including normal, accident, and severe accident events.

  3. Plans for the CIT [Compact Ignition Tokamak] instrumentation and control system

    Extensive experience with previous fusion experiments (TFTR, MFTF-B and others) is driving the design of the Instrumentation and Control System (I and C) for the Compact Ignition Tokamak (CIT) to be built at Princeton. The new design will reuse much equipment from TFTR and will be subdivided into six major parts: machine control, machine data acquisition, plasma diagnostic instrument control and instrument data acquisition, the database, shot sequencing and safety interlocks. In a major departure from previous fusion experiment control systems, the CIT machine control system will be a commercial process control system. Since the machine control system will be purchased as a completely functional product, we will be able to concentrate development manpower in plasma diagnostic instrument control, data acquisition, data processing and analysis, and database systems. We will discuss the issues driving the design, give a design overview and state the requirements upon any prospective commercial process control system

  4. Instrument hardware and software upgrades at IPNS

    IPNS is in the process of upgrading their time-of-flight neutron scattering instruments with improved hardware and software. The hardware upgrades include replacing old VAX Qbus and Multibus-based data acquisition systems with new systems based on VXI and VME. Hardware upgrades also include expanded detector banks and new detector electronics. Old VAX Fortran-based data acquisition and analysis software is being replaced with new software as part of the ISAW project. ISAW is written in Java for ease of development and portability, and is now used routinely for data visualization, reduction, and analysis on all upgraded instruments. ISAW provides the ability to process and visualize the data from thousands of detector pixels, each having thousands of time channels. These operations can be done interactively through a familiar graphical user interface or automatically through simple scripts. Scripts and operators provided by end users are automatically included in the ISAW menu structure, along with those distributed with ISAW, when the application is started

  5. On detector related machine and instrumentation issues

    This is a summary report of the panel discussions on detector related machine and instrumentation issues. Each of the panel members presented an introductory presentation of the following topics. Those are the three most revealing future experiments (by G. Kane), calorimetry for jets and total energy (by U. Amaldi), tracking and momentum (by R. Schwitters), identification of e, μ and other particles (by G. Wolf), trigger and data acquisition (by M. Breidenbach) and building large detectors in cooperation with industry (by S. Orito). In the discussion on the detectors at future large hadron colliders, much emphasis was given to calorimetric measurement, muon measurement, and microvertex detection. There is a need for inexpensive and radiation-hardened front-end electronics for all detectors. As to data acquisition and analysis, the use of a sequence of successive trigger levels with a large number of emulators (of the order of 100) in the last stage and the use of optical discs for data storage would be needed at the highest luminosity. It is clear that the development of the instrumentation technique mentioned constitutes a prerequisite for the efficient use of future large hadron colliders. When considering the detectors for future large positron-electron colliders, some of the technical problems mentioned were drastically simplified, in particular those related to the high collision rate like signal pile-up, radiation damage and fast data processing.

  7. Program Instrumentation and Trace Analysis

    Havelund, Klaus; Goldberg, Allen; Filman, Robert; Rosu, Grigore; Koga, Dennis (Technical Monitor)

    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

  13. Conceptual design of the BPX instrumentation and control system

    The Burning Plasma Experiment (BPX) Instrumentation and Control system provides supervision, remote control, monitoring, data acquisition and data handling for BPX subsystems. Researchers located at the BPX site and other universities/laboratories will have access to the facility in support of the remote operation, physics planning, analysis, and coordination of experimental objectives for BPX. BPX Instrumentation and Control (I ampersand C) must support two types of subsystems: Engineering-like secure systems and physics-like flexible systems. Engineering-like systems (e.g., vacuum, water cooling, etc.) are characterized by: Stable, routine operation, well known data sources, extensive control and monitoring and minor data acquisition/analysis requirements. These systems' requirements best match industrial process control applications which support high reliability and availability, mimic displays, trending, alarming, and continuous control. Physics-like systems (plasma diagnostics, experimental operations) are characterized by: Changing operational requirements; unique data sources and data handling; minor control and monitoring; and extensive data acquisition/analysis requirements. These systems' requirements best match emerging laboratory information management systems (LIMS) which support high flexibility, configuration toolkits, analysis and display toolkits and data management tools. Some diagnostics may not be able to use commercial systems for their data-intensive applications; however, the control and data handling systems of the diagnostics instruments will utilize instrumentation technologies, computer networks, processors and databases tailored to their unique characteristics

    Czerwinski, Lars; Nixdorf, Jakob; Florio, Giuseppe Di; Gilch, Peter

    2016-07-01

    Femtosecond stimulated Raman microscopy (FSRM) is a nonlinear technique for rapid broadband Raman imaging. It utilizes a few femtosecond probe pulse and a narrow bandwidth pump pulse. Using a fast (20 kHz) multi-channel detector, stimulated Raman spectra can be recorded with an acquisition time as short as 0.1 ms. In this Letter, spectra of neat benzonitrile at different acquisition speeds are presented to benchmark the FSRM setup. Furthermore, chemical maps of a multi-phase polymer blend are recorded using the fastest acquisition rate possible with the current instrument. PMID:27367091

  18. Instrumentation for environmental monitoring

    In the last few years a much greater emphasis has been placed upon understanding, controlling and monitoring the environmental effects of the advancing technologies. This has resulted in rapid advances in techniques for environmental monitoring. To aid the concerned scientist in keeping abreast of these developments, the Lawrence Berkeley Laboratory publishes a collection of volumes entitled Instrumentation for Environmental Monitoring. Separated into four volumes covering four media, AIR, WATER, RADIATION, and BIOMEDICAL, they provide a source book for three types of material: (1) Monitoring Rationale. They describe the characteristics, forms, and effects of a wide variety of pollutants and the means of controlling them. Federal regulations are explained and summarized. (2) Analytical Techniques. Methods of determining specific pollutants are described with special emphasis on the principles that form the basis of instrumental methods. (3) Commercial Instrumentation. The features of most commercially available instrumentation used for the determination and monitoring of each pollutant are presented in a manner that facilitates instrumental comparisons. Examples of the types of material in the volumes and the use of the volumes are presented

  19. The keyboard instruments.

    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;).

  20. TRIGA instrumentation modernization

    Due to alterations made, the present reactor instrumentation is a mixture of old electron tube and modern semiconductor techniques. This mixture and the limited space in the control console, a non-modular system etc. render the making of service, maintenance and improvements difficult. Problems concerning the obtaining of spare parts for the old instrumentation are also expected. The present cabling will not be satisfactory in the long run and the risk of fires is significant. There is one common high voltage source for all four neutron detectors and no redundancy. Separate HV supplies including trip actuators are recommended for the nuclear channels. The water activity measurement system (with a GM tube) in the primary circuit is insufficient. Some modifications and replacements have been made in the present instrumentation, but it can hardly be used 10-20 years ahead without extensive replacements. It has been decided to renew the whole instrumentation in 1981. Much emphasis will be laid on standardization, flexibility, reliability, service and repair possibilities. The new instrumentation will be based on modern industrial standard modular units, cards etc. (including standardized signal output ranges, electronic testing possibilities, the use of isolation amplifiers etc.). Since the development in electronics is rapid, provisions should be made for some changes in the future. Standard unit and module systems make it easier to carry out such changes

    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...

  5. Advanced instrumentation for reprocessing.

    Cipiti, Benjamin B.

    2005-10-01

    Recent interest in reprocessing nuclear fuel in the U.S. has led to advanced separations processes that employ continuous processing and multiple extraction steps. These advanced plants will need to be designed with state-of-the-art instrumentation for materials accountancy and control. This research examines the current and upcoming instrumentation for nuclear materials accountancy for those most suited to the reprocessing environment. Though this topic has received attention time and again in the past, new technologies and changing world conditions require a renewed look and this subject. The needs for the advanced UREX+ separations concept are first identified, and then a literature review of current and upcoming measuring techniques is presented. The report concludes with a preliminary list of recommended instruments and measurement locations.

  6. ISSUERS OF FINANCIAL INSTRUMENTS

    2016-05-01

    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.

  7. Characteristics of protective instrumentation

    Protective Instrumentation (PI) for Nuclear Power Plants (NPP) is a general term for an highly reliable instrumentation, which provides information for keeping the system within safe limits, for initation of countermeasures in the case of an incident or for mitigation of consequences of an accident. In German NPPs one can find a hierarchical structure of protective instrumentation, wherein the Reactor Protection System (RPS) has the highest priority. To meet the reliability requirements different design principles are used, like - redundancy - diversity - fail safe - decoupling. The presentation gives an overview about the different design principles and characterizes their reliability aspects. As an example for the technical realization the RPS of a German NPP is discussed in some detail. Furthermore some information about other type of PI is given and reliability aspects of the interaction of operating personell with these systems are mentioned. (orig.)

  8. Ozone Monitoring Instrument

    de Vries, Johan

    The Ozone Monitoring Instrument is a trace gas monitoring instrument in the line of GOME (ERS-2) and Sciamachy (ENVISAT). Following these instruments, OMI provides UV-visible spectroscopy with a resolution sufficient to separate out the various absorbing trace gases (using DOAS or `Full' retrieval), but shaped as an imaging spectrometer. This means that a two dimensional detector is used where one dimension records the spectrum and the other images the swath. The scanning mechanism from the GOME and Sciamachy is not required anymore and there are considerable advantages with respect to simultaneous measurement of swath pixels, polarisation and obtainable swath width. The OMI consortium for a phase B is formed by Fokker Space & Systems and TPD in the Netherlands and VTT in Finland. In the presentation UV-visible atmospheric remote sensing will be placed in perspective and the OMI will be explaned.

  9. Eigenvalues and musical instruments

    Howle, V. E.; Trefethen, Lloyd N.

    2001-10-01

    Most musical instruments are built from physical systems that oscillate at certain natural frequencies. The frequencies are the imaginary parts of the eigenvalues of a linear operator, and the decay rates are the negatives of the real parts, so it ought to be possible to give an approximate idea of the sound of a musical instrument by a single plot of points in the complex plane. Nevertheless, the authors are unaware of any such picture that has ever appeared in print. This paper attempts to fill that gap by plotting eigenvalues for simple models of a guitar string, a flute, a clarinet, a kettledrum, and a musical bell. For the drum and the bell, simple idealized models have eigenvalues that are irrationally related, but as the actual instruments have evolved over the generations, the leading five or six eigenvalues have moved around the complex plane so that their relative positions are musically pleasing.

  10. Spectroelectrochemical Instrument Measures TOC

    Kounaves, Sam

    2011-01-01

    A spectroelectrochemical instrument has been developed for measuring the total organic carbon (TOC) content of an aqueous solution. Measurements of TOC are frequently performed in environmental, clinical, and industrial settings. Until now, techniques for performing such measurements have included, various ly, the use of hazardous reagents, ultraviolet light, or ovens, to promote reactions in which the carbon contents are oxidized. The instrument now being developed is intended to be a safer, more economical means of oxidizing organic carbon and determining the TOC levels of aqueous solutions and for providing a low power/mass unit for use in planetary missions.

    2006-01-01

    Archimedes said, "Give me the place to stand, and a lever long enough, and I will move the Earth." Economists have their own powerful lever: the instrumental variable estimator. The instrumental variable estimator can avoid the bias that ordinary least squares suffers when an explanatory variable in a regression is correlated with the regression's disturbance term. But, like Archimedes lever, instrumental variable estimation requires both a valid instrument on which to stand and an instrument...

  5. High Quality Acquisition of Surface Electromyography – Conditioning Circuit Design

    The acquisition of Surface Electromyography (SEMG) signals is used for many applications including the diagnosis of neuromuscular diseases, and prosthesis control. The diagnostic quality of the SEMG signal is highly dependent on the conditioning circuit of the SEMG acquisition system. This paper presents the design of an SEMG conditioning circuit that can guarantee to collect high quality signal with high SNR such that it is immune to environmental noise. The conditioning circuit consists of four stages; consisting of an instrumentation amplifier that is used with a gain of around 250; 4th order band pass filter in the 20–500Hz frequency range as the two initial stages. The third stage is an amplifier with adjustable gain using a variable resistance; the gain could be changed from 1000 to 50000. In the final stage the signal is translated to meet the input requirements of data acquisition device or the ADC. Acquisition of accurate signals allows it to be analyzed for extracting the required characteristic features for medical and clinical applications. According to the experimental results, the value of SNR for collected signal is 52.4 dB which is higher than the commercial system, the power spectrum density (PSD) graph is also presented and it shows that the filter has eliminated the noise below 20 Hz

  6. Power station instrumentation

    Power stations are characterized by a wide variety of mechanical and electrical plant operating with structures, liquids and gases working at high pressures and temperatures and with large mass flows. The voltages and currents are also the highest that occur in most industries. In order to achieve maximum economy, the plant is operated with relatively small margins from conditions that can cause rapid plant damage, safety implications, and very high financial penalties. In common with other process industries, power stations depend heavily on control and instrumentation. These systems have become particularly significant, in the cost-conscious privatized environment, for providing the means to implement the automation implicit in maintaining safety standards, improving generation efficiency and reducing operating manpower costs. This book is for professional instrumentation engineers who need to known about their use in power stations and power station engineers requiring information about the principles and choice of instrumentation available. There are 8 chapters; chapter 4 on instrumentation for nuclear steam supply systems is indexed separately. (Author)

  13. Neutron instrumentation for biology

    Mason, S.A. [Institut Laue-Langevin, Grenoble (France)

    1994-12-31

    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.

  14. Radiation monitoring instruments

    Radiation exposure to humans can be broadly classified as internal and external exposure. Sealed sources, which are unlikely to cause internal exposure, are used almost exclusively in radiotherapy. This chapter deals with the monitoring of external exposures. 1) External exposure monitoring refers to measuring: Radiation levels in and around work areas; Radiation levels around radiotherapy equipment or source containers; . Equivalent doses received by individuals working with radiation. 2) Radiation monitoring is carried out: to assess workplace conditions and individual exposures; To ensure acceptably safe and satisfactory radiological conditions in the workplace; to keep records of monitoring, over a long period of time, for the purposes of regulation or good practice. 3) Radiation monitoring instruments are used both for area monitoring and for individual monitoring. The instruments used for measuring radiation levels are referred to as area survey meters (or area monitors) and the instruments used for recording the equivalent doses received by individuals working with radiation are referred to as personal dosimeters (or individual dosimeters). All instruments must be calibrated in terms of the appropriate quantities used in radiation protection

  15. Integrating Nephelometer Instrument Handbook

    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).

  16. Rain radar instrument definition

    Vincent, Nicolas; Chenebault, J.; Suinot, Noel; Mancini, Paolo L.

    1996-12-01

    As a result of a pre-phase a study, founded by ESA, this paper presents the definition of a spaceborne Rain Radar, candidate instrument for earth explorer precipitation mission. Based upon the description of user requirements for such a dedicated mission, a mission analysis defines the most suitable space segment. At system level, a parametric analysis compares pros and cons of instrument concepts associated with rain rate retrieval algorithms in order to select the most performing one. Several trade-off analysis at subsystem level leads then to the definition of the proposed design. In particular, as pulse compression is implemented in order to increase the radar sensitivity, the selected method to achieve a pulse response with a side-lobe level below--60 dB is presented. Antenna is another critical rain radar subsystem and several designs are com pared: direct radiating array, single or dual reflector illuminated by single or dual feed arrays. At least, feasibility of centralized amplification using TWTA is compared with criticality of Tx/Rx modules for distributed amplification. Mass and power budgets of the designed instrument are summarized as well as standard deviations and bias of simulated rain rate retrieval profiles. The feasibility of a compliant rain radar instrument is therefore demonstrated.

  17. Designing Intelligent Instruments

    Knuth, Kevin H.; Erner, Philip M.; Frasso, Scott

    2007-11-01

    Remote science operations require automated systems that can both act and react with minimal human intervention. One such vision is that of an intelligent instrument that collects data in an automated fashion, and based on what it learns, decides which new measurements to take. This innovation implements experimental design and unites it with data analysis in such a way that it completes the cycle of learning. This cycle is the basis of the Scientific Method. The three basic steps of this cycle are hypothesis generation, inquiry, and inference. Hypothesis generation is implemented by artificially supplying the instrument with a parameterized set of possible hypotheses that might be used to describe the physical system. The act of inquiry is handled by an inquiry engine that relies on Bayesian adaptive exploration where the optimal experiment is chosen as the one which maximizes the expected information gain. The inference engine is implemented using the nested sampling algorithm, which provides the inquiry engine with a set of posterior samples from which the expected information gain can be estimated. With these computational structures in place, the instrument will refine its hypotheses, and repeat the learning cycle by taking measurements until the system under study is described within a pre-specified tolerance. We will demonstrate our first attempts toward achieving this goal with an intelligent instrument constructed using the LEGO MINDSTORMS NXT robotics platform.

  20. Digital instrumentation and dead-time processing for radionuclide metrology

    Most of the acquisition chains used in radionuclide metrology are based on NIM modules. These analogue setups have been thoroughly tested for decades now, becoming a reference in the field. Nevertheless, the renewal of ageing modules and the need for extra features both call for the development of new acquisition schemes based on digital processing. In this article, several technologies usable for instrumentation are first presented. A review of past and present projects is made in the second part, highlighting the fundamental role of dead-time management. The last part is dedicated to the description of two digital systems developed at LNE-LNHB. The first one has been designed for the instrumentation of a NaI(Tl) well-type crystal set-up, while the second one is used for the management of three photomultipliers in the framework of the TDCR method and as a part of the development of a digital platform for coincidence counting.

  1. Million revolution accelerator beam instrument for logging and evaluation

    A data acquisition and analysis instrument for the processing of accelerator beam position monitor (BPM) signals has been assembled and used preliminarily for beam diagnosis of the Fermilab accelerators. Up to eight BPM (or other analogue) channels are digitized and transmitted to an acquisition Sun workstation and from there both to a monitor workstation and a workstation for off-line (but immediate) data analysis. A coherent data description format permits fast data object transfers to and from memory, disk and tape, across the Sun ethernet. This has helped the development of both general purpose and experiment-specific data analysis, presentation and control tools. Flexible software permits immediate graphical display in both time and frequency domains. The instrument acts simultaneously as a digital oscilloscope, as a network analyzer and as a correlating, noise-reducing spectrum analyzer. 2 refs., 3 figs

    Full Text Available This article compares the effectiveness of three learning strategies (memory strategies for ESL vocabulary acquisition. 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.

  15. The IAEA universal nondestructive assay data acquisition platform (UNAP)

    The IAEA Department of Safeguards is developing a new series of instruments for safeguarding nuclear material. The Universal NDA Data Acquisition Platform (UNAP) will be the next generation data acquisition system attended and unattended non-destructive assay measurement equipment. The primary goal of the UNAP development is for the new module to become the IAEA standard and replace existing Non-Destructive Assay (NDA) modules such as the JSR-12, the MiniGrand, the Advanced Multiplicity Shift Register (AMSR), and the JSR-14. The inputs to the UNAP will be a super-set of the existing inputs of all these previous modules with flexibility to anticipate future developments. The core measurement capabilities of the UNAP include three multiplicity shift registers clocked at 50 MHz, an eight channel combination scalar-derandomizer with output to one of the shift registers, dual current mode measurement channels with 30 femto-ampere resolution, a list mode channel with 100 nanosecond resolution, four programmable threshold single channel analyzers (SCA), a 4-20 mA channel, and several discrete digital inputs and isolated contact closure outputs. All measurement data is acquired and reduced by a Freescale PowerQUICC processor and is locally stored in a 16 GByte solid state drive. The UNAP will authenticate and encrypt the data for transmission across the 100-BaseT Ethernet interface to the data acquisition system. In this paper the IAEA will provide more detailed information concerning the operational and performance characteristics of the UNAP instrument. We will share knowledge from the rapid-development utilizing the commercial cPCI bus. We will provide a status of the instrument development from Los Alamos and from the processor and commercial UNAP vendors and updates to our target milestones. Finally, we will provide information on how the UNAP will be used with future safeguards systems in large numbers at nuclear facilities

    Full Text Available Responsible business notion is more and more present in Polish economy, however the results of the research carried out in Polish business still shows a low level of CRS idea knowledge, especially in small and medium companies. Although responsible business notion is generally known, its details, ways of preparing strategy, instruments and what is more its benefits are still narrowly spread. Many business people face the lack of knowledge and information, which on one hand make it easier to spread and deepen wrong stereotypes connected with this notion and on the other hand make business people unwilling to implement CRS in their companies. The subjects of this article are examples of instruments which are responsible for realization of social responsibility strategy.

    2005-01-01

    This paper reviews recent developments in methods for dealing with weak instruments (IVs) in IV regression models. The focus is more on tests and confidence intervals derived from tests than on estimators. The paper also presents new testing results under "many weak IV asymptotics," which are relevant when the number of IVs is large and the coefficients on the IVs are relatively small. Asymptotic power envelopes for invariant tests are established. Power comparisons of the conditional likelih...

  13. Embedded instrumentation systems architecture

    Visnevski, Nikita A.

    2007-04-01

    This paper describes the operational concept of the Embedded Instrumentation Systems Architecture (EISA) that is being developed for Test and Evaluation (T&E) applications. The architecture addresses such future T&E requirements as interoperability, flexibility, and non-intrusiveness. These are the ultimate requirements that support continuous T&E objectives. In this paper, we demonstrate that these objectives can be met by decoupling the Embedded Instrumentation (EI) system into an on-board and an off-board component. An on-board component is responsible for sampling, pre-processing, buffering, and transmitting data to the off-board component. The latter is responsible for aggregating, post-processing, and storing test data as well as providing access to the data via a clearly defined interface including such aspects as security, user authentication and access control. The power of the EISA architecture approach is in its inherent ability to support virtual instrumentation as well as enabling interoperability with such important T&E systems as Integrated Network-Enhanced Telemetry (iNET), Test and Training Enabling Architecture (TENA) and other relevant Department of Defense initiatives.

  14. Tank depletion flow instruments

    A new flowmetering system is developed to measure and control flow without the need for an inline flowmeter. Flowrate is determined from the rate of level change in reference vessel. This system is unique in its use of balance pots for zero suppression to enable range amplification. The result is an accuracy in flow measurement and control as good as $plus or minus$1%. The system uses state-of-the-art digital integrated circuits with a crystal time base in conjunction with the time-proven pneumatic bubbler probe low range transmitters. The benefits are (1) reduced radiation exposure to personnel during maintenance of flowmeters for radioactive streams since instruments are all located in an operating area isolated from the process by four feet of concrete, (2) reduced volume of solid nuclear wastes through processing efficiencies, (3) reduced cost of chemicals involved, (4) increased speed of flowrate determination, (5) reduced maintenance time and material cost to correct flow instrument component failures, (6) no obstruction to flow in the process stream, and (7) reduced cost of instrumentation to determine flowrate. A disadvantage is the requirement that flow must be related to tank level thus only one unknown flow into or out of a given vessel at a time may be metered and controlled. 1 ref

  15. CLIC-ACM: Acquisition and Control System

    Bielawski, B; Magnoni, S

    2014-01-01

    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...

  16. FHR Process Instruments

    Holcomb, David Eugene [ORNL

    2015-01-01

    Fluoride salt-cooled High temperature Reactors (FHRs) are entering into early phase engineering development. Initial candidate technologies have been identified to measure all of the required process variables. 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

    The COMET cards (encoding and time marking) serve to determine the energies and the time correlations of radiations detected during a multiparameter experiment while avoiding any extra specific module like coincidence circuits or delays) to set this time correlation. For each detected radiation, the arrival time information as well as the amplitude of the detected signal, are encoded. The results of these amplitude and time coding are associated to create an event. In this way, each detector is an independent source which provides a building block of the general information obtained by all the detectors. The COMET cards are associated with a NARVAL data acquisition system. This document is the instruction booklet of the COMET-NARVAL acquisition system.

  3. Music and Early Language Acquisition

    Anthony K. Brandt

    2012-09-01

    Full Text Available Language is typically viewed as fundamental to human intelligence. Music, while recognized as a human universal, is often treated as an ancillary ability—one dependent on or derivative of language. In contrast, we argue that it is more productive from a developmental perspective to describe spoken language as a special type of music. A review of existing studies presents a compelling case that musical hearing and ability is essential to language acquisition. In addition, the authors challenge the prevailing view that music cognition matures more slowly than language and is more difficult; instead, the authors present evidence that music learning matches the speed and effort of language acquisition. We conclude that music merits a central place in our understanding of human development.

  4. Is merging and acquisition profitable?

    This report deals with mergers and acquisitions in the electricity sector in Norway. The background is the fact that the profitability of these activities proves to be low. In buying, it is typically the selling shareholder who profits from the transaction, while the buying company does not really earn much. This result appears to be a robust result both in different countries, between sectors and independent of methodology. The report provides theoretical justification for merging and buying up and empirical evaluations of the effects of company integration. It is asserted that what can be learned in general from the literature may also occur in the European power sector. Furthermore, the report discusses the challenges faced by the companies if they want to expand through mergers and acquisitions

  5. DANSS Experiment Data Acquisition System

    Hons, Zdenek

    2016-01-01

    DANSS (Detector of the reactor AntiNeutrino based on Solid Scintillator) is a project aiming to measure a spectrum of reactor antineutrinos using inverse beta decay (IBD) in a plastic scintillator. The detector is located close to an industrial nuclear reactor core and is covered by passive and active shielding. It is expected to detect about 15000 IBD events per day. Light from the detector is sensed by PMT and SiPM. This paper describes the data acquisition system used for data readout of the 50 detector PMT channels and active shielding. Theoretical approach to the data acquisition is described and two possible solutions using QDCs and digitizers are discussed. Also described are the results of the DAQ performance during routine data taking operation of the detector.

  6. COLDEX New Data Acquisition Framework

    Grech, Christian

    2015-01-01

    COLDEX (COLD bore EXperiment) is an experiment of the TE-VSC group installed in the Super Proton Synchrotron (SPS) which mimics a LHC type cryogenic vacuum system. In the framework of the High Luminosity upgrade of the LHC (HL-LHC project), COLDEX has been recommissioned in 2014 in order to validate carbon coatings performances at cryogenic temperature with LHC type beams. To achieve this mission, a data acquisition system is needed to retrieve and store information from the different experiment’s systems (vacuum, cryogenics, controls, safety) and perform specific calculations. This work aimed to completely redesign, implement, test and operate a brand new data acquisition framework based on communication with the experiment’s PLCs for the devices potentially available over network. The communication protocol to the PLCs is based on data retrieval both from CERN middleware infrastructures (CMW, JAPC) and on a novel open source Simatic S7 data exchange package over TCP/IP (libnodave).

    2014-01-01

    In this paper we describe the design, the construction, the commissioning and the operation of the Data Acquisition (DAQ) and Experiment Control Systems (ECS) of the ALICE experiment at the CERN Large Hadron Collider (LHC). The DAQ and the ECS are the systems used respectively for the acquisition of all physics data and for the overall control of the experiment. They are two computing systems made of hundreds of PCs and data storage units interconnected via two networks. The collection of experimental data from the detectors is performed by several hundreds of high-speed optical links. We describe in detail the design considerations for these systems handling the extreme data throughput resulting from central lead ions collisions at LHC energy. The implementation of the resulting requirements into hardware (custom optical links and commercial computing equipment), infrastructure (racks, cooling, power distribution, control room), and software led to many innovative solutions which are described together with ...

  9. Small instrument to volcanic seismic signals

    Carreras, Normandino; Gomariz, Spartacus; Manuel, Antoni

    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

    In a sample of 326 U.S. acquisitions between 1975 and 1987, three types of acquisitions have systematically lower and predominantly negative announcement period returns to bidding firms. The returns to bidding shareholders are lower when their firm diversifies, when it buys a rapidly growing target, and when its managers performed poorly before the acquisition. These results suggest that managerial objectives may drive acquisitions that reduce bidding firms' values. Copyright 1990 by American...

  2. Review of accelerator instrumentation

    Some of the problems associated with the monitoring of accelerator beams, particularly storage rings' beams, are reviewed along with their most common solutions. The various electrode structures used for the measurement of beam current, beam position, and the detection of the bunches' transverse oscillations, yield pulses with sub-nanosecond widths. The electronics for the processing of these short pulses involves wide band techniques and circuits usually not readily available from industry or the integrated circuit market: passive or active, successive integrations, linear gating, sample-and-hold circuits with nanosecond acquisition time, etc. This report also presents the work performed recently for monitoring the ultrashort beams of colliding linear accelerators or single-pass colliders. To minimize the beam emittance, the beam position must be measured with a high resolution, and digitized on a pulse-to-pulse basis. Experimental results obtained with the Stanford two-mile Linac single bunches are included

  3. Integrated instrumentation & computation environment for GRACE

    Dhekne, P. S.

    2002-03-01

    The project GRACE (Gamma Ray Astrophysics with Coordinated Experiments) aims at setting up a state of the art Gamma Ray Observatory at Mt. Abu, Rajasthan for undertaking comprehensive scientific exploration over a wide spectral window (10's keV - 100's TeV) from a single location through 4 coordinated experiments. The cumulative data collection rate of all the telescopes is expected to be about 1 GB/hr, necessitating innovations in the data management environment. As real-time data acquisition and control as well as off-line data processing, analysis and visualization environment of these systems is based on the us cutting edge and affordable technologies in the field of computers, communications and Internet. We propose to provide a single, unified environment by seamless integration of instrumentation and computations by taking advantage of the recent advancements in Web based technologies. This new environment will allow researchers better acces to facilities, improve resource utilization and enhance collaborations by having identical environments for online as well as offline usage of this facility from any location. We present here a proposed implementation strategy for a platform independent web-based system that supplements automated functions with video-guided interactive and collaborative remote viewing, remote control through virtual instrumentation console, remote acquisition of telescope data, data analysis, data visualization and active imaging system. This end-to-end web-based solution will enhance collaboration among researchers at the national and international level for undertaking scientific studies, using the telescope systems of the GRACE project.

  4. Direct digital mammography image acquisition

    Mammography is a branch of radiology which could benefit greatly from the assimilation of digital imaging technologies. Computerized enhancement techniques could be used to ensure optimum presentation of all clinical images. Beyond this it will facilitate powerful new clinical resources such as computer-assisted diagnosis, tele-mammography, plus digital image management and archiving. An essential precursor to all these advances is the availability of appropriate direct digital mammography (DDM) image-acquisition system(s) to capture high-quality breast X-ray image data at the outset. The only practical DDM image-acquisition system currently available is (photo-stimulable phosphor) computed radiography. Modern computed mammography (CM) uses similar radiation doses to the patient and produces equivalent, albeit different, image quality to screen-film mammography. Computed mammography offers superior rendition of the skin edge and sub-cutaneous tissue and dense parenchyma, while ensuring equivalent micro-calcification detectability. Meanwhile, a variety of new technical approaches to DDM are under active investigation and/or development which promise to supercede film-based mammography. These new (second generation) DDM technologies promise the radiologist superior image quality combined with significant dose savings compared with contemporary imaging systems. In this review we describe and compare the physical and clinical characteristics of CM and the various emerging DDM image-acquisition technologies. (orig.). With 7 figs., 1 tab

  5. Data acquisition for sensor systems

    Taylor, H Rosemary

    1997-01-01

    'Data acquisition' is concerned with taking one or more analogue signals and converting them to digital form with sufficient accu­ racy and speed to be ready for processing by a computer. The increasing use of computers makes this an expanding field, and it is important that the conversion process is done correctly because information lost at this stage can never be regained, no matter how good the computation. The old saying - garbage in, garbage out - is very relevant to data acquisition, and so every part of the book contains a discussion of errors: where do they come from, how large are they, and what can be done to reduce them? The book aims to treat the data acquisition process in depth with less detailed chapters on the fundamental principles of measure­ ment, sensors and signal conditioning. There is also a chapter on software packages, which are becoming increasingly popular. This is such a rapidly changing topic that any review of available pro­ grams is bound to be out of date before the book re...

  6. Photovoltaic module parameters acquisition model

    Highlights: • Photovoltaic five-parameter model is proposed using Matlab® and Simulink. • The model acquisits input sparse data matrix from stigmatic measurement. • Computer simulations lead to continuous I–V and P–V characteristics. • Extrapolated I–V and P–V characteristics are in hand. • The model allows us to predict photovoltaics exploitation in different conditions. - Abstract: This paper presents basic procedures for photovoltaic (PV) module parameters acquisition using MATLAB and Simulink modelling. In first step, MATLAB and Simulink theoretical model are set to calculate I–V and P–V characteristics for PV module based on equivalent electrical circuit. Then, limited I–V data string is obtained from examined PV module using standard measurement equipment at standard irradiation and temperature conditions and stated into MATLAB data matrix as a reference model. Next, the theoretical model is optimized to keep-up with the reference model and to learn its basic parameters relations, over sparse data matrix. Finally, PV module parameters are deliverable for acquisition at different realistic irradiation, temperature conditions as well as series resistance. Besides of output power characteristics and efficiency calculation for PV module or system, proposed model validates computing statistical deviation compared to reference model

  7. A PC-based single-ADC multi-parameter data acquisition system

    A personal computer (PC) based mult parameter data acquisition system using the Microsoft Window operating environment has been designed and constructed. An IBI AT compatible personal computer with an Intel 486DX5 microprocessor was combined with a National Instruments ATIDIO 32 digital I/O card, a single Canberra 8713 ADC with 13-bit resolution and a modified Canberra 8223 8-input analog multiplexer to acquil data from experiments carried out at the UML Van de Graa accelerator. The accelerator data acquisition (ADAC) computer environment was programmed in Microsoft Visual BASIC for use i Windows. ADAC allows event-mode data acquisition with up to eight parameters (modifiable to 64) and the simultaneous display parameters during acquisition. Additional features of ADAC include replay of event-mode data and graphical analysis/display of data. TV ADAC environment is easy to upgrade or expand, inexpensive 1 implement, and is specifically designed to meet the needs of nuclei spectroscopy

  8. Meta-tool support for knowledge acquisition

    Knowledge acquisition is a major bottleneck in expert system development. Specialized, or domain-oriented, knowledge acquisition tools can provide efficient support in restricted domains. However, the principal drawback with specialized knowledge acquisition tools is that the tool cost per expert system developed is typically high. Meta-level environments is an approach to support knowledge engineers in developing such knowledge acquisition tools. Meta-tools, i.e. tools for creating knowledge acquisition tools, can be used to specify and automatically generate knowledge acquisition tools for single domains and even single applications. This thesis presents an abstract architecture approach to the specification of knowledge acquisition tools. In this framework knowledge acquisition tools can be specified according to an abstract model of the target tool architecture. DOTS is a meta-tool that supports the abstract-architecture specification scheme. Knowledge engineers can use DOTS to specify and generate domain-oriented knowledge acquisition tools that can be used by domain experts directly. Two implementations of knowledge acquisition tools for different domains are presented in this thesis. These tools are representatives of knowledge acquisition tools that are desirable to generate form meta-tools. One of them was hand-crafted and specialized to the domain of protein purification planning. The other emerged form an evaluation of DOTS by developing a knowledge acquisition tool in a different domain (troubleshooting laboratory equipment). Results from this evaluation are also reported.

  12. Virtual instrumentation on mobile devices for deployment in nuclear installations

    The virtual instrumentation can be defined as a layer of software and hardware, added to a general purpose computer, so that users can interact with the computer in the same way that they interacted with traditional electronic instruments such as oscilloscopes, multi-meters and signal generators, and may add other functions defined by software. The virtual instrumentation gets a new integration environment, little explored yet, with the great growth that occurred in the mobile devices area. Nowadays it is possible to take measurements in more places by combining mobile devices with data acquisition hardware to create extremely portable and interconnected measurement systems. This paper shows the development of software and hardware that make possible the use of instrumentation on mobile devices for monitoring nuclear installations. It's presented the hardware and the application software for data acquisition of radiation monitors, developed to iOS devices. It's also shown the possibilities of hardware and software to develop near real-time data transfer to and from the field in nuclear installations, with benefits in efficiency, safety and productivity.

  13. A miniaturized ASIC-based multichannel scaler instrument

    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 operational. 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. The instrument was specifically designed for determining environmental uranium concentration levels in ground water monitoring applications, with sufficient sensitivity to analyzed low-level process streams and effluent. The analysis method employed is based on phosphorescence decay techniques thoroughly covered in published literature

    2009-06-15

    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.

  2. Software quality assurance plan for void fraction instrument

    Gimera, M.

    1994-10-18

    Waste Tank SY-101 has been the focus of extensive characterization work over the past few years. The waste continually generates gases, most notably hydrogen, which are periodically released from the waste. Gas can be trapped in tank waste in three forms: as void gas (bubbles), dissolved gas, or absorbed gas. Void fraction is the volume percentage of a given sample that is comprised of void gas. The void fraction instrument (VFI) acquires the data necessary to calculate void fraction. This document covers the product, Void Fraction Data Acquisition Software. The void fraction software being developed will have the ability to control the void fraction instrument hardware and acquire data necessary to calculate the void fraction in samples. This document provides the software quality assurance plan, verification and validation plan, and configuration management plan for developing the software for the instrumentation that will be used to obtain void fraction data from Tank SY-101

  3. Integrated instrument platform for in situ characterization of tank wastes

    An integrated instrument platform will support robotic characterization of radioactive chemical waste materials in the underground storage tanks at the Department of Energy's Hanford Site in Richland, Washington. The support platform supplies the basic support infrastructure needed to perform remotely controlled robotic deployment of sensors. A trailer serves as a field operations center, providing power and utilities, data acquisition and control equipment, common instrumentation, and test equipment. As part of the platform development effort, information on operational requirements and interface specifications is being compiled and distributed to potential suppliers of instrumentation. An overall characterization strategy has been developed, incorporating the currently identified characterization missions. This strategy will evolve over time and should provide a baseline to assist in planning for future deployment of characterization technology

    This paper analyzes the effect of foreign acquisition on survival and employment growth of targets using data on Swedish manufacturing plants.We separate targeted plants into those within Swedish MNEs, Swedish exporting non-MNEs, and purely domestic firms. The results, controlling for possible...... endogeneity of acquisition using IV and propensity score matching approaches suggest that acquisition by foreign owners increases the lifetime of the acquired plants only if the plant was an exporter. The effect is robust to controlling for domestic acquisitions and differs between horizontal and vertical...... acquisitions. We find robust positive employment growth effects only for exporters and only if the takeover is vertical....

  6. Incore instrument device

    An incore instrument device has an integrally disposed touch panel having a function of displaying an operation indication method such as for setting of conditions for incore measurement and information processing and results of the incore measurement and a function capable of conducting operation indication such as for setting conditions and information processing for incore measurement relative to a control section upon touching an information position on a displayed information. In addition, an information processing section comprising a man-machine function program formed so as to recognize the content of the operation indication for the incore measurement by touching and let the control section to conduct it is disposed to the outside by way of a communication interface. In addition, a programming device is disposed for forming and rewriting the program of the man-machine function relative to the information processing section. Then, when various indication operations are conducted upon performing incore measurement, a view point can be concentrated to one predetermined point thereby enabling to improve the operationability without danger. In addition, the programming of the man-machine function does not apply unnecessary load to the control section in the incore instrumentation device. (N.H.)

  7. The QUIET Instrument

    Bischoff, C.; et al.

    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.

  8. Radiation instrumentation: radiological chemistry

    Program efforts were concentrated in the following areas: development of low-level radiochemical laboratory techniques, in situ monitoring techniques, and activation analysis technology. Four different techniques were evaluated for borehole analysis of uranium and thorium ores. These involved the detection of fission product photons after 252Cf activation, the detection of low-energy gamma rays, the direct measurement of the 1001 keV photon from /sup 242m/Pa, a 238U daughter, and isotopic excitation x-ray fluorescence spectroscopy. X-ray fluorescence spectroscopy and detection of uranium daughter photons allowed 0.01% uranium to be detected. X-ray spectrometry of rare earth elements following activation analysis also allowed better elemental detection sensitivities to be obtained than did the detection of high-energy photons identified with a Ge(Li) detector in typical instrumental neutron activation analysis. An activation analysis facility is under development utilizing 252Cf in a 235U-fueled subcritical assembly. This assembly will be used to develop cyclic activation analysis techniques for some 65 elements in environmental matrices with sensitivities varying from parts per million to parts per billion. A study was initiated to identify instrumentation required for the measurement of transuranium elements associated with power reactor fuels. Transuranium isotopes, 237Pu, 238Pu, 239Pu, 241Am, 243Am, and 244Cm can be identified through low energy photons or x-rays emitted following alpha emission with planar intrinsic Ge detectors

  10. An Instrumental Innovation

    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.

  13. Improving Acquisition Outcomes with Contextual Ambidexterity

    Meglio, Olimpia; King, David R.; Risberg, Annette

    The results of research on mergers and acquisitions often point to a need to improve acquisition outcomes and lessen the organizational turmoil that can often follow integration efforts. We assert that viewing acquisition integration through the lens of contextual ambidexterity may improve...... acquisition outcomes in two ways: by providing an integrated solution to the economic and social tensions in acquisitions, and by enabling managers to effectively confront the competing needs of task and human integration. We also posit that by building on contextual ambidexterity, we can extend the...... possibilities for both research and practice regarding task and human integration in acquisitions. We also emphasize the role of an integration manager and integration mechanisms in enabling contextual ambidexterity for successful acquisition integration. Finally, we identify implications for research and...

  16. EARS : Repositioning data management near data acquisition.

    Sinquin, Jean-Marc; Sorribas, Jordi; Diviacco, Paolo; Vandenberghe, Thomas; Munoz, Raquel; Garcia, Oscar

    2016-04-01

    The EU FP7 Projects Eurofleets and Eurofleets2 are an European wide alliance of marine research centers that aim to share their research vessels, to improve information sharing on planned, current and completed cruises, on details of ocean-going research vessels and specialized equipment, and to durably improve cost-effectiveness of cruises. Within this context logging of information on how, when and where anything happens on board of the vessel is crucial information for data users in a later stage. This forms a primordial step in the process of data quality control as it could assist in the understanding of anomalies and unexpected trends recorded in the acquired data sets. In this way completeness of the metadata is improved as it is recorded accurately at the origin of the measurement. The collection of this crucial information has been done in very different ways, using different procedures, formats and pieces of software in the context of the European Research Fleet. At the time that the Eurofleets project started, every institution and country had adopted different strategies and approaches, which complicated the task of users that need to log general purpose information and events on-board whenever they access a different platform loosing the opportunity to produce this valuable metadata on-board. Among the many goals the Eurofleets project has, a very important task is the development of an "event log software" called EARS (Eurofleets Automatic Reporting System) that enables scientists and operators to record what happens during a survey. EARS will allow users to fill, in a standardized way, the gap existing at the moment in metadata description that only very seldom links data with its history. Events generated automatically by acquisition instruments will also be handled, enhancing the granularity and precision of the event annotation. The adoption of a common procedure to log survey events and a common terminology to describe them is crucial to provide

  17. Behavioural Motives of Acquisition of Solar-driven Equipment

    Shkurupska Iryna O.

    2013-12-01

    Full Text Available The article identifies needs of the target group, namely structure of motives, which justify making a decision to buy, in order to create efficient marketing strategy of an enterprise, which sell solar-driven equipment in Ukraine. There are five segments in the domestic market of helio-systems: individual consumers, recreation industry, agrarian industry, construction and social spheres. The article allocates 15 motives of acquisition of the solar-driven equipment for these segments, the most important of which are price, availability of solar energy, alternative price and energy saving. Besides, the structure of such motives is determined for each segment individually. In order to choose specific marketing instruments in the policy of promotion of solar-driven equipment, the article identifies differences in the form of goals of use and motives of acquisition between the specified consumer segments. The article reveals certain barriers that interfere with acquisition of solar-driven equipment – low level of trust into helio-systems, conservatism of consumers, absence of free applications for consumers – overcoming which is only possible with the help of certain marketing actions.

    2011-01-01

    The Dark Energy Camera (DECam) data acquisition and control system is called the Survey Image System Process Integration (SISPI). Implemented as a distributed multi-processor system, SISPI consists of a set of processes that will coordinate and perform image acquisition and deliver images to the data management system for processing. Separate processes for instrument control, image building and analysis, image acquisition and observatory control are built on top of an infrastructure layer that provides message passing and communications. Additional system components include a flexible configuration system and the facility database. The command protocol is implemented in Python using a client-server design pattern derived from the SML and SCLN communications software developed at CTIO. A publish-subscribe model has been added to support the distribution of telemetry data and alarm messages. The design of the graphical user interfaces follows the Model-View-Controller approach to distinguish between the actual information and the graphical representation of the data. We will present the software architecture of the SISPI system and report on the current status of the project.

    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). PMID:25423656

  20. Instrumentation of multi-channel counter experiments

    Recent experience in instrumenting several nuclear physics experiments has demonstrated the feasibility of automating the data-acquisition phases of the experiment. Electronic circuits are employed wherever the rate of data flow would be slowed down by the use of human operations. Information is selected, temporarily stored and then recorded in a form suitable for immediate entry into a computer. Experimenters thus freed from the tedious aspects of data collection can devote their time to studying the results of the experiment. Potentially useful nuclear events are first selected by the fast (10-8 s) logic part of the instrumentation. Circuits performing simple logical functions are packaged in modular form for easy grouping into particular coincidence, gating, and mixing configurations. Circuits with slower response time (10-6 s and greater) are used to perform temporary storage and recording operations. Automatic test routines are used to initially align the equipment as well as provide continuous calibration during the experiments. Some of the high-speed circuits are described as well as the methods used to incorporate them into a large counting system. (author)
