    Full Text Available Abstract Background Accurate analysis of CT brain scans is vital for diagnosis and treatment of Traumatic Brain Injuries (TBI. Automatic processing of these CT brain scans could speed up the decision making process, lower the cost of healthcare, and reduce the chance of human error. In this paper, we focus on automatic processing of CT brain images to segment and identify the ventricular systems. The segmentation of ventricles provides quantitative measures on the changes of ventricles in the brain that form vital diagnosis information. Methods First all CT slices are aligned by detecting the ideal midlines in all images. The initial estimation of the ideal midline of the brain is found based on skull symmetry and then the initial estimate is further refined using detected anatomical features. Then a two-step method is used for ventricle segmentation. First a low-level segmentation on each pixel is applied on the CT images. For this step, both Iterated Conditional Mode (ICM and Maximum A Posteriori Spatial Probability (MASP are evaluated and compared. The second step applies template matching algorithm to identify objects in the initial low-level segmentation as ventricles. Experiments for ventricle segmentation are conducted using a relatively large CT dataset containing mild and severe TBI cases. Results Experiments show that the acceptable rate of the ideal midline detection is over 95%. Two measurements are defined to evaluate ventricle recognition results. The first measure is a sensitivity-like measure and the second is a false positive-like measure. For the first measurement, the rate is 100% indicating that all ventricles are identified in all slices. The false positives-like measurement is 8.59%. We also point out the similarities and differences between ICM and MASP algorithms through both mathematically relationships and segmentation results on CT images. Conclusion The experiments show the reliability of the proposed algorithms. The

  6. Automated drawing generation system

    International Nuclear Information System (INIS)

    Since automated CAD drawing generation systems still require human intervention, improvements were focussed on an interactive processing section (data input and correcting operation) which necessitates a vast amount of work. As a result, human intervention was eliminated, the original objective of a computerized system. This is the first step taken towards complete automation. The effects of development and commercialization of the system are as described below. (1) The interactive processing time required for generating drawings was improved. It was determined that introduction of the CAD system has reduced the time required for generating drawings. (2) The difference in skills between workers preparing drawings has been eliminated and the quality of drawings has been made uniform. (3) The extent of knowledge and experience demanded of workers has been reduced. (author)

    Nothing has improved petroleum product loading in recent years more than terminal automation systems. The presence of terminal automation systems (TAS) at loading racks has increased operational efficiency and safety and enhanced their accounting and management capabilities. However, like all finite systems, they occasionally malfunction or fail. Proper servicing and maintenance can minimize this. And in the unlikely event a TAS breakdown does occur, prompt and effective troubleshooting can reduce its impact on terminal productivity. To accommodate around-the-clock loading at racks, increasingly unattended by terminal personnel, TAS maintenance, servicing and troubleshooting has become increasingly demanding. It has also become increasingly important. After 15 years of trial and error at petroleum and petrochemical storage and transfer terminals, a number of successful troubleshooting programs have been developed. These include 24-hour {open_quotes}help hotlines,{close_quotes} internal (terminal company) and external (supplier) support staff, and {open_quotes}layered{close_quotes} support. These programs are described.

  8. LINAC control automation system

    International Nuclear Information System (INIS)

    A 7 MeV Electron Beam Linear Accelerator (LINAC) being used for pulse radiolysis experiments at RC and CDD, B.A.R.C. has been automated with a PLC based control panel designed and developed by Computer Division, B.A.R.C.. The control panel after power on switches ON various units in a pre-defined sequence and intervals on a single turn of START key from OFF to ON position. The control panel also generates various ramp signals in a pre-defined sequence and rate and steady values and feeds to the LINAC bringing it to the ready for experiment condition. Similarly on a single turn of STOP key from OFF to ON position, the panel ramps down the various signals in pre-defined manners and makes OFF the various units in predefined sequence and timing providing safety to the machine. The steady values for various signals are on line settable as and when required so. This automation system relieves the operator from fatigue of time consuming manual ramping up or down of various signals and running around in four rooms for switching ON or OFF the various units enhancing efficiency and safety. This also facilitates the user scientist to do start up and shutdown operation in the absence of skilled operators and thus adds flexibility for working up to extended timing. This unit has been working satisfactorily since August 2002. For extraordinary condition automation to manual or vice versa change over has been provided. (author)

    2015-01-01

    This book presents a number of aspects to be considered in the development of disassembly automation, including the mechanical system, vision system and intelligent planner. The implementation of cognitive robotics increases the flexibility and degree of autonomy of the disassembly system. Disassembly, as a step in the treatment of end-of-life products, can allow the recovery of embodied value left within disposed products, as well as the appropriate separation of potentially-hazardous components. In the end-of-life treatment industry, disassembly has largely been limited to manual labor, which is expensive in developed countries. Automation is one possible solution for economic feasibility. The target audience primarily comprises researchers and experts in the field, but the book may also be beneficial for graduate students.

    Cardiac MRI is an accurate and reproducible technique for the assessment of left ventricular volumes and function. The accuracy of automated segmentation and the effects of manual adjustments have not been determined in children. To evaluate automated segmentation and the effects of manual adjustments for left ventricular parameter quantification in pediatric cardiac MR images. Left ventricular parameters were evaluated in 45 children with suspected myocarditis (age 13.4 ± 3.5 years, range 4-17 years) who underwent cardiac MRI. Dedicated software was used to automatically segment and adjust the parameters. Results of end-diastolic volume, end-systolic volume, stroke volume, myocardial mass, and ejection fraction were documented before and after apex/base adjustment and after apex/base/myocardial contour adjustment. The software successfully detected the left ventricle in 42 of 45 (93.3%) children; failures occurred in the smallest and youngest children. Of those 42 children, automatically segmented end-diastolic volume (EDV) was 151 ± 47 ml, and after apex/base adjustment it was 146 ± 45 ml, after apex/base/myocardial contour adjustment 146 ± 45 ml. The corresponding results for end-systolic volume (ESV) were 66 ± 32 ml, 63 ± 29 ml and 64 ± 28 ml; for stroke volume (SV) they were 85 ± 25 ml, 83 ± 23 ml and 83 ± 23 ml; for ejection fracture (EF) they were 57 ± 10%, 58 ± 9% and 58 ± 9%, and for myocardial mass (MM) they were 104 ± 31 g, 95 ± 31 g and 94 ± 30 g. Statistically significant differences were found when comparing the EDV/ESV/MM results, the EF results after apex/base adjustment and after apex/base/myocardial contour adjustment and the SV results (except for comparing the SVs after apex/base adjustment and after apex/base/myocardial contour adjustment). Automated segmentation for the evaluation of left ventricular parameters in pediatric MR images proved to be feasible. Automated segmentation + apex/base adjustment provided clinically

    A software application has been developed to aid law enforcement and government intelligence gathering organizations in the translation and analysis of foreign language documents with potential intelligence content. The Automated Document Analysis System (ADAS) provides the capability to search (data or text mine) documents in English and the most commonly encountered foreign languages, including Arabic. Hardcopy documents are scanned by a high-speed scanner and are optical character recognized (OCR). Documents obtained in an electronic format bypass the OCR and are copied directly to a working directory. For translation and analysis, the script and the language of the documents are first determined. If the document is not in English, the document is machine translated to English. The documents are searched for keywords and key features in either the native language or translated English. The user can quickly review the document to determine if it has any intelligence content and whether detailed, verbatim human translation is required. The documents and document content are cataloged for potential future analysis. The system allows non-linguists to evaluate foreign language documents and allows for the quick analysis of a large quantity of documents. All document processing can be performed manually or automatically on a single document or a batch of documents.

    Full Text Available Objective To study the clinical, neuroimaging and histopathological features of intracranial germinoma.  Methods One case of intracranial germinoma with ventricular system dissemination was reported, and related literatures were reviewed.  Results A 34-year-old male complained of progressive dizziness for 30 d and manifested unsteady gait for 45 d. Radiological examinations revealed low signal intensity on T1WI and hyperintense on T2WI in the corpus callosum, left cerebellum, around the fourth ventricle, aqueduct mesencephalon, the ventral pons and pineal region, with even or uneven enhancement after contrast. The clinical initial diagnosis was "intracranial multiple focal lesions and high possibility of multiple sclerosis". After well response to glucocorticoid impact and dehydration, the patient stopped taking drugs but presented relapse and exacerbation. Later, he underwent biopsy on pineal region and was diagnosed as intracranial germinoma. Microscopically, the big germ cells and lymphocytes coexisted. Tumor cells were epithelioid cells with transparent cytoplasm, prominent nuclei and mitotic activity. Lymphocytes were distributed along interstitial substance of vessel and fiber, and individual syncytiotrophoblasts were sprasely distributed. Immunohistochemical staining showed tumor cells were positive for CD117 and OCT3/4, and the syncytiotrophoblasts were positive for β-human chorionic gonadotropin ( β-hCG. The clinical symptoms were completely alleviated after radiotherapy and chemotherapy.  Conclusions Because of the sensitivity for radiotherapy and chemotherapy, intracranial germinoma can be diagnosed and treated early to improve its prognosis. However, it is very easy to disseminate along with ventricular system and form multiple lesions, leading to atypical clinical and imaging manifestations, which is a big challenge for clinical diagnosis. doi: 10.3969/j.issn.1672-6731.2014.05.010

    One of the most important recent improvements in cardiology is the use of ventricular assist devices (VADs) to help patients with severe heart diseases, especially when they are indicated to heart transplantation. The Institute Dante Pazzanese of Cardiology has been developing an implantable centrifugal blood pump that will be able to help a sick human heart to keep blood flow and pressure at physiological levels. This device will be used as a totally or partially implantable VAD. Therefore, an improvement on device performance is important for the betterment of the level of interaction with patient's behavior or conditions. But some failures may occur if the device's pumping control does not follow the changes in patient's behavior or conditions. The VAD control system must consider tolerance to faults and have a dynamic adaptation according to patient's cardiovascular system changes, and also must attend to changes in patient conditions, behavior, or comportments. This work proposes an application of the mechatronic approach to this class of devices based on advanced techniques for control, instrumentation, and automation to define a method for developing a hierarchical supervisory control system that is able to perform VAD control dynamically, automatically, and securely. For this methodology, we used concepts based on Bayesian network for patients' diagnoses, Petri nets to generate a VAD control algorithm, and Safety Instrumented Systems to ensure VAD system security. Applying these concepts, a VAD control system is being built for method effectiveness confirmation. PMID:21595713

  19. Programmable automation systems in PSA

    International Nuclear Information System (INIS)

    The Finnish safety authority (STUK) requires plant specific PSAs, and quantitative safety goals are set on different levels. The reliability analysis is more problematic when critical safety functions are realized by applying programmable automation systems. Conventional modeling techniques do not necessarily apply to the analysis of these systems, and the quantification seems to be impossible. However, it is important to analyze contribution of programmable automation systems to the plant safety and PSA is the only method with system analytical view over the safety. This report discusses the applicability of PSA methodology (fault tree analyses, failure modes and effects analyses) in the analysis of programmable automation systems. The problem of how to decompose programmable automation systems for reliability modeling purposes is discussed. In addition to the qualitative analysis and structural reliability modeling issues, the possibility to evaluate failure probabilities of programmable automation systems is considered. One solution to the quantification issue is the use of expert judgements, and the principles to apply expert judgements is discussed in the paper. A framework to apply expert judgements is outlined. Further, the impacts of subjective estimates on the interpretation of PSA results are discussed. (orig.) (13 refs.)

  8. A fully automated determination of the left ventricular region of interest in nuclear angiocardiography

    International Nuclear Information System (INIS)

    The precise delineation of the left ventricular projection area is an essential part in the quantitative analysis of nuclear angiocardiograms. We have devised an algorithm that permits automation of this step, based on a one-dimensional Laplace operator whose kernel is 2, 2, -2, -4, -2, 2, 2. The operator characteristically enhances 'valleys' more than edges and, therefore, favors septal and the valve plane detection. The operator is applied vertically, horizontally, and along both diagonals. Each pass is immediately followed by a local maximum search during which the image resulting from the Laplacian operator is reduced to a binary one, with zeros every where except where a local maximum was found along the path of the operator. This resultant image yields a closed 'edge' around the left ventricle, even though many structures outside the left ventricle are also delineated. However, the centroid of the ventricle is defined from functional criteria and the region of interest is defined from centroid to first edge. The method has been applied to first-pass and gated studies in anterior and 450 left anterior oblique views. In 100 successive cases the ejection fraction obtained automatically was compared to the manual result. (orig./MG)

    This study aims to develop a prototype for an Automated Car Park Management System that will increase the quality of service of parking lots through the integration of a smart system that assists motorist in finding vacant parking lot. The research was based on implementing an operating system and a monitoring system for parking system without the use of manpower. This will include Parking Guidance and Information System concept which will efficiently assist motorists and ensures the safety of the vehicles and the valuables inside the vehicle. For monitoring, Optical Character Recognition was employed to monitor and put into list all the cars entering the parking area. All parking events in this system are visible via MATLAB GUI which contain time-in, time-out, time consumed information and also the lot number where the car parks. To put into reality, this system has a payment method, and it comes via a coin slot operation to control the exit gate. The Automated Car Park Management System was successfully built by utilizing microcontrollers specifically one PIC18f4550 and two PIC16F84s and one PIC16F628A.

  10. Automating occupational protection records systems

    International Nuclear Information System (INIS)

    Occupational protection records have traditionally been generated by field and laboratory personnel, assembled into files in the safety office, and eventually stored in a warehouse or other facility. Until recently, these records have been primarily paper copies, often handwritten. Sometimes, the paper is microfilmed for storage. However, electronic records are beginning to replace these traditional methods. The purpose of this paper is to provide guidance for making the transition to automated record keeping and retrieval using modern computer equipment. This paper describes the types of records most readily converted to electronic record keeping and a methodology for implementing an automated record system. The process of conversion is based on a requirements analysis to assess program needs and a high level of user involvement during the development. The importance of indexing the hard copy records for easy retrieval is also discussed. The concept of linkage between related records and its importance relative to reporting, research, and litigation will be addressed. 2 figs

  11. Clinical evaluation of 64-slice CT assessment of global left ventricular function using automated cardiac phase selection

    International Nuclear Information System (INIS)

    Left ventricular (LV) function provides prognostic information regarding the morbidity and mortality of patients. An automated cardiac phase selection algorithm has the potential to support the assessment of LV function with computed tomography (CT). This algorithm is clinically evaluated for 64-slice cardiac CT. Examinations of twenty consecutive patients were selected. Electrocardiogram gated contrast-enhanced CT was performed. Reconstructions were performed using an automated and a manual method, followed by the determination of the global LV function. Significances were tested using 2-sided Student's t-tests. Reduction in post processing time and storage capacity were estimated. A slightly smaller mean end-systolic volume was found with the automated method (52±18 ml vs 54±17 ml, p=0.02, r=0.99). The mean LV ejection fraction was slightly larger with the automated method (65±8% vs 64±8%, p=0.004, r=0.99). The estimated reduction in post processing time was maximal 5 min per patient with a potential 80% data storage reduction. Results of the automated phase selection algorithm are similar to the manual method. The automated tool reduces post processing time, reconstruction time and transfer time. (author)

This an electromechanical system which includes certain mechanical parts that involves one base stand on which one vertical metallic frame is mounted and hinged to this vertical stand is an in humanized effort seems inadequate in this era making necessary the use of Electronics, Computer in the manufacturing processes leading to the concept of Automated Manufacturing System (AMS.The ball bearing stack automation is an effort in this regard. In our project we go for stack automation for any object for example a ball bearing, be that is still a manual system there. It will be microcontroller based project control system equipped with microcontroller 89C51 from any manufacturer like Atmel or Philips. This could have been easily implemented if a PLC could be used for manufacturing the staking unit but I adopted the microcontroller based system so that some more modification in the system can be effected at will as to use the same hardware .Although a very small object i.e. ball bearig or small nut and fixture will be tried to be stacked, the system with more precision and more power handling capacity could be built for various requirements of the industry. For increasing more control capacity, we can use another module of this series. When the bearing is ready, it will be sent for packing. This is sensed by an inductive sensor. The output will be proceeds by PLC and microcontroller card which will be driving the assembly in order to put it into pads or flaps. This project will also count the total number of bearings to be packed and will display it on a LCD for real time reference and a provision is made using a higher level language using hyper terminal of the computer

    1975-01-01

    A one-twenty-fifth scale model of the key components of an automated parking garage system is described. The design of the model required transferring a vehicle from an entry level, vertically (+Z, -Z), to a storage location at any one of four storage positions (+X, -X, +Y, +Y, -Y) on the storage levels. There are three primary subsystems: (1) a screw jack to provide the vertical motion of the elevator, (2) a cam-driven track-switching device to provide X to Y motion, and (3) a transfer cart to provide horizontal travel and a small amount to vertical motion for transfer to the storage location. Motive power is provided by dc permanent magnet gear motors, one each for the elevator and track switching device and two for the transfer cart drive system (one driving the cart horizontally and the other providing the vertical transfer). The control system, through the use of a microprocessor, provides complete automation through a feedback system which utilizes sensing devices.

    Full Text Available This paper presents an efficient and innovative system for automated classification of periodontal diseases, The strength of our technique lies in the fact that it incorporates knowledge from the patients' clinical data, along with the features automatically extracted from the Haematoxylin and Eosin (H&E stained microscopic images. Our system uses image processing techniques based on color deconvolution, morphological operations, and watershed transforms for epithelium & connective tissue segmentation, nuclear segmentation, and extraction of the microscopic immunohistochemical features for the nuclei, dilated blood vessels & collagen fibers. Also, Feedforward Backpropagation Artificial Neural Networks are used for the classification process. We report 100% classification accuracy in correctly identifying the different periodontal diseases observed in our 30 samples dataset.

    Besides remarkable improvements of neonatal medical therapy, neurological morbidity remains a major concern in preterm infants. In particular, intracranial hemorrhage is a severe complication strongly correlated to poor neurological outcome. For early clinical assessment of intracranial hemorrhage and its impact on the ventricular system, cranial sonography is an important bedside diagnostic tool. Reference values of ventricular sizes are available in relation to gestational age (GA). So far, it has not been demonstrated that ventricular size values are also reliable in relation to birth weight (BW). In this study, we performed cranial ultrasonography in 250 preterm and term newborn infants. Measurements of the intracranial ventricular system by cranial ultrasound examination were performed within 72 h after birth. We determined ventricular index, anterior horn width, width of the third ventricle, width and length of the fourth ventricle for statistical analysis in relation to BW and GA. GA ranged from 23 weeks, 3 days to 42 weeks, 1 day (mean: 33 weeks), BW ranged from 345 to 5620 g (mean: 2146 g). Ventricular index and fourth ventricle width revealed a significant correlation to birth weight with r=0.75, each. A significant correlation to birth weight was also obtained for width and length of the third ventricle (r=0.55 and 0.47, respectively). Correlations obtained for ventricular measures in relation to GA were similar to those referring to BW. In preterm and term infants, ventricular sizes in relation to BW seem reliable for assessment and monitoring of ventricular pathologies, i.e. after intracranial hemorrhage. PMID:26378487

    Supine exercise radionuclide angiography was performed in 367 men to assess left ventricular (LV) systolic response to exercise; 58 had systemic hypertension without LV hypertrophy on a resting electrocardiogram and 309 were normotensive. All patients met the following criteria defining a low pretest likelihood of coronary artery disease: age less than 50 years; normal electrocardiographic response to exercise; absence of typical or atypical chest pain; and exercise heart rate greater than 120 beats/min. Patients taking beta-receptor blockers were excluded. There were no significant differences between hypertensive and normotensive groups in peak exercise heart rate, workload or exercise duration. However, hypertensive patients had significantly higher peak exercise systolic blood pressures and peak exercise rate-pressure products. There were no differences between patients with and without hypertension in resting ejection fraction, peak exercise ejection fraction (hypertensive patients 0.71 +/- 0.01, normotensive patients 0.70 +/- 0.05) or change in ejection fraction at peak exercise (hypertensive patients 0.07 +/- 0.01, normotensive patients 0.07 +/- 0.04). Diastolic and systolic ventricular volumes tended to be smaller in the hypertensive patients, but the difference was not statistically significant. The change in systolic volume with exercise was similar in the 2 groups (hypertensive -10 +/- 3 ml/m2, normotensive -10 +/- 1 ml/m2). In the absence of electrocardiographic evidence of LV hypertrophy, systemic hypertension does not influence LV systolic response to exercise. PMID:2140008

    In this paper we describe the design and important implementation details of the new automated system for processing satellite telemetry developedat Skobeltsyn Institute of Nuclear Physics of Moscow State University (SINP MSU) . We discuss the most common tasks and pitfall for such systems built around data stream from a single spacecraft or a single instrument, and suggest a solution that allows to quickly develop telemetry processing modules and to integrate them with an existing polling mechanism, support infrastructure and data storage in Oracle or MySQL database systems. We also demonstrate the benefits of this approach using modules for processing three different spacecraft data streams: Coronas-Photon (2009-003A), Tatiana-2 (2009-049D) and Meteor-M no.1 (2009-049A). The data format and protocols used by each of these spacecraft have distinct peculiarities, which nevertheless did not pose a problem for integrating their modules into the main system. Remote access via web interface to Oracle databases and sophisticated visualization tools create a possibility of efficient scientific exploitation of satellite data. Such a system is already deployed at the web portal of the Space Monitoring Data Center (SMDC) of SINP MSU (http://smdc.sinp.msu.ru).

    The purpose was to evaluate a new semi-automated 3D region-growing segmentation algorithm for functional analysis of the left ventricle in multislice CT (MSCT) of the heart. Twenty patients underwent contrast-enhanced MSCT of the heart (collimation 16 x 0.75 mm; 120 kV; 550 mAseff). Multiphase image reconstructions with 1-mm axial slices and 8-mm short-axis slices were performed. Left ventricular volume measurements (end-diastolic volume, end-systolic volume, ejection fraction and stroke volume) from manually drawn endocardial contours in the short axis slices were compared to semi-automated region-growing segmentation of the left ventricle from the 1-mm axial slices. The post-processing-time for both methods was recorded. Applying the new region-growing algorithm in 13/20 patients (65%), proper segmentation of the left ventricle was feasible. In these patients, the signal-to-noise ratio was higher than in the remaining patients (3.2{+-}1.0 vs. 2.6{+-}0.6). Volume measurements of both segmentation algorithms showed an excellent correlation (all P{<=}0.0001); the limits of agreement for the ejection fraction were 2.3{+-}8.3 ml. In the patients with proper segmentation the mean post-processing time using the region-growing algorithm was diminished by 44.2%. On the basis of a good contrast-enhanced data set, a left ventricular volume analysis using the new semi-automated region-growing segmentation algorithm is technically feasible, accurate and more time-effective.

  5. Cardiac arrhythmias and left ventricular hypertrophy in systemic hypertension

    International Nuclear Information System (INIS)

    Background: Hypertensive left ventricular hypertrophy (LVH) is associated with increased risk of arrhythmias and mortality. Objective was to investigate the prevalence of cardiac arrhythmias and LVH in systemic hypertension. Methods: In all subjects blood pressure was measured, electrocardiography and echocardiography was done. Holter monitoring and exercise test perform in certain cases. There were 500 hypertensive patients, 156 (31.2%) men and 344 (69%) women >30 years of age in the study. Among them 177 (35.4%) were diabetic, 224 (45%) were dyslipidemia, 188 (37.6%) were smokers, and 14 (3%) had homocysteinemia. Mean systolic BP (SBP) was 180 +- 20 mm Hg and diastolic BP (DBP) was 95 +- 12 in male and female patients. Left ventricular mass index (LVMI) was 119.2 +- 30 2 2gm/m in male while 103 +- 22 gm/m in female patients. Palpitation was seen in 126 (25%) male and 299 (59.8%) female patients. Atrial fibrillation was noted in 108 (21.6%) male and 125 (25%) female patients, 30 (6%) male and 82 (16.4%) female patients had atrial flutter. Ventricular tachycardia was noted in 37 (7.4%) male and 59 (11.8%) female patients. Holter monitoring showed significant premature ventricular contractions (PVC'S) in 109 (21.8%) male and 128 (25.69%) female patients while Holter showed atrial arrhythmias (APC'S) in 89 (17.8%) males and 119 (23.8%) females. Angiography findings diagnosed coronary artery disease in 119 (23.8%) with CAD male and 225 (45%) without CAD while 47 (9.4%) females presented with CAD and 109 (21.8%) without CAD. Conclusion: A significant association has been demonstrated between hypertension and arrhythmias. Diastolic dysfunction of the left ventricle, left atrial size and function, as well as LVH have been suggested as the underlying risk factors for supraventricular, ventricular arrhythmias and sudden death in hypertensives with LVH.

    Snook, Bryan E.

    2010-01-01

    The Automated Computer Access Request (AutoCAR) system is a Web-based account provisioning application that replaces the time-consuming paper-based computer-access request process at Johnson Space Center (JSC). Auto- CAR combines rules-based and role-based functionality in one application to provide a centralized system that is easily and widely accessible. The system features a work-flow engine that facilitates request routing, a user registration directory containing contact information and user metadata, an access request submission and tracking process, and a system administrator account management component. This provides full, end-to-end disposition approval chain accountability from the moment a request is submitted. By blending both rules-based and rolebased functionality, AutoCAR has the flexibility to route requests based on a user s nationality, JSC affiliation status, and other export-control requirements, while ensuring a user s request is addressed by either a primary or backup approver. All user accounts that are tracked in AutoCAR are recorded and mapped to the native operating system schema on the target platform where user accounts reside. This allows for future extensibility for supporting creation, deletion, and account management directly on the target platforms by way of AutoCAR. The system s directory-based lookup and day-today change analysis of directory information determines personnel moves, deletions, and additions, and automatically notifies a user via e-mail to revalidate his/her account access as a result of such changes. AutoCAR is a Microsoft classic active server page (ASP) application hosted on a Microsoft Internet Information Server (IIS).

    This presentation describes work to integrate a set of tools to support early model-based analysis of failures and hazards due to system-software interactions. The tools perform and assist analysts in the following tasks: 1) extract model parts from text for architecture and safety/hazard models; 2) combine the parts with library information to develop the models for visualization and analysis; 3) perform graph analysis and simulation to identify and evaluate possible paths from hazard sources to vulnerable entities and functions, in nominal and anomalous system-software configurations and scenarios; and 4) identify resulting candidate scenarios for software integration testing. There has been significant technical progress in model extraction from Orion program text sources, architecture model derivation (components and connections) and documentation of extraction sources. Models have been derived from Internal Interface Requirements Documents (IIRDs) and FMEA documents. Linguistic text processing is used to extract model parts and relationships, and the Aerospace Ontology also aids automated model development from the extracted information. Visualizations of these models assist analysts in requirements overview and in checking consistency and completeness.

    Errors in field wiring can result in significant correction costs (if the errors are discovered prior to use), in erroneous or unusable data (if the errors are not discovered in time), or in serious accidents (if the errors corrupt critical data). Detailed field wiring checkout rework are tedious and expensive, but they are essential steps in the quality assurance process for large, complex instrumentation and control systems. A recent Oak Ridge National Laboratory (ORNL) development, the CONFiguration IDEnification System (CONFIDES) automates verification of field wiring. In CONFIDES, an identifier module is installed on or integrated into each component (e.g., sensor, actuator, cable, distribution panel) to be verified. Interrogator modules, controlled by a personal computer (PC), are installed at the connections of the field wiring to the inputs of the data acquisition and control system (DACS). Interrogator modules poll the components connected to each channel of the DACS and can determine the path taken by each channel's signal to or from the end device for that channel. The system will provide not only the identification (ID) code for the cables and patch panels in the path to a particular sensor or actuator but for individual cable conductor IDs as well. One version of the system uses existing signal wires for communications between CONFIDES modules. Another, more powerful version requires a single dedicated conductor in each cable. Both version can operate with or without instrument power applied and neither interferes with the normal operation of the DACS. Identifier modules can provide a variety of information including status and calibration data.

    An implantable, electrically powered pump that will provide tether-free circulatory support is being developed. The blood pump consists of a seamless polyurethane sac within a polysulfone case. Björk-Shiley Monostrut valves provide unidirectional flow. The blood sac is compressed by a pusher plate with a stroke of 1.9 cm and actuated by a brushless direct-current electric motor and motion translator. The current unit is completely sealed, and inductive coupling techniques provide the electrical energy. The system has an implantable electronic control system as well as a battery that provides 30 minutes of operation when the external coil is disconnected. During normal operation, however, the pump is powered by a portable battery pack or by house current. The unit can pump 8.5 L/min at physiologic pressures. Twenty-six animals have had circulatory support for a period of more than 1 week. The average period of pumping was 62 days; the longest was nearly 8 months. Experiments were terminated in 18 animals because of pump-related problems and in 8 because of biologically related problems. Studies to date are very encouraging and suggest that, with further refinement, a reliable 2-year assist pump that will have important clinical application can be developed. PMID:8445929

    We describe here an automated imaging system developed at the Center for High Throughput Minimally Invasive Radiation Biodosimetry. The imaging system is built around a fast, sensitive sCMOS camera and rapid switchable LED light source. It features complete automation of all the steps of the imaging process and contains built-in feedback loops to ensure proper operation. The imaging system is intended as a back end to the RABiT-a robotic platform for radiation biodosimetry. It is intended to automate image acquisition and analysis for four biodosimetry assays for which we have developed automated protocols: The Cytokinesis Blocked Micronucleus assay, the γ-H2AX assay, the Dicentric assay (using PNA or FISH probes) and the RABiT-BAND assay.

    Systolic global longitudinal strain (GLS) is emerging as a useful metric of ventricular function in heart failure and usually assessed using post-processing software. The purpose of this study was to investigate whether longitudinal strain (LS) derived using manual-tracings of ventricular lengths (manual-LS) can be reliable and time efficient when compared to LS obtained by post-processing software (software-LS). Apical 4-chamber view images were retrospectively examined in 50 healthy controls, 100 patients with dilated cardiomyopathy (DCM), and 100 with hypertrophic cardiomyopathy (HCM). We measured endocardial and mid-wall manual-LS and software-LS, using peak of average regional curve [software-LS(a)] and global ventricular lengths [software-LS(l)] according to definition of Lagragian strain. We compared manual-LS and software-LS by using Bland-Altman plot and coefficient of variation (COV). In addition, test-retest was also performed for further assessment of variability in measurements. While manual-LS was obtained in all subjects, software-LS could be obtained in 238 subjects (95 %). The time spent for obtaining manual-LS was significantly shorter than for the software-LS (94 ± 39 s vs. 141 ± 79 s, P controls]. The COV for manual and software derived LS were below 6 %. Test-retest showed good variability for both methods (COVs were 5.8 and 4.7 for endocardial and mid-wall manual-LS, and 4.6 and 4.9 for endocardial and mid-wall software-LS(a), respectively. Manual-LS appears to be as reproducible as software-LS; this may be of value especially when global strain is the metric of interest. PMID:26578468

  18. Performance of automated software in the assessment of segmental left ventricular function in cardiac CT: Comparison with cardiac magnetic resonance

    International Nuclear Information System (INIS)

    To evaluate the accuracy, reliability and time saving potential of a novel cardiac CT (CCT)-based, automated software for the assessment of segmental left ventricular function compared to visual and manual quantitative assessment of CCT and cardiac magnetic resonance (CMR). Forty-seven patients with suspected or known coronary artery disease (CAD) were enrolled in the study. Wall thickening was calculated. Segmental LV wall motion was automatically calculated and shown as a colour-coded polar map. Processing time for each method was recorded. Mean wall thickness in both systolic and diastolic phases on polar map, CCT, and CMR was 9.2 ± 0.1 mm and 14.9 ± 0.2 mm, 8.9 ± 0.1 mm and 14.5 ± 0.1 mm, 8.3 ± 0.1 mm and 13.6 ± 0.1 mm, respectively. Mean wall thickening was 68.4 ± 1.5 %, 64.8 ± 1.4 % and 67.1 ± 1.4 %, respectively. Agreement for the assessment of LV wall motion between CCT, CMR and polar maps was good. Bland-Altman plots and ICC indicated good agreement between CCT, CMR and automated polar maps of the diastolic and systolic segmental wall thickness and thickening. The processing time using polar map was significantly decreased compared with CCT and CMR. Automated evaluation of segmental LV function with polar maps provides similar measurements to manual CCT and CMR evaluation, albeit with substantially reduced analysis time. (orig.)

    2006-01-01

    Full Text Available The present study describes an auxiliary tool in the diagnosis of left ventricular (LV segmental wall motion (WM abnormalities based on color-coded echocardiographic WM images. An artificial neural network (ANN was developed and validated for grading LV segmental WM using data from color kinesis (CK images, a technique developed to display the timing and magnitude of global and regional WM in real time. We evaluated 21 normal subjects and 20 patients with LVWM abnormalities revealed by two-dimensional echocardiography. CK images were obtained in two sets of viewing planes. A method was developed to analyze CK images, providing quantitation of fractional area change in each of the 16 LV segments. Two experienced observers analyzed LVWM from two-dimensional images and scored them as: 1 normal, 2 mild hypokinesia, 3 moderate hypokinesia, 4 severe hypokinesia, 5 akinesia, and 6 dyskinesia. Based on expert analysis of 10 normal subjects and 10 patients, we trained a multilayer perceptron ANN using a back-propagation algorithm to provide automated grading of LVWM, and this ANN was then tested in the remaining subjects. Excellent concordance between expert and ANN analysis was shown by ROC curve analysis, with measured area under the curve of 0.975. An excellent correlation was also obtained for global LV segmental WM index by expert and ANN analysis (R² = 0.99. In conclusion, ANN showed high accuracy for automated semi-quantitative grading of WM based on CK images. This technique can be an important aid, improving diagnostic accuracy and reducing inter-observer variability in scoring segmental LVWM.

    Full Text Available Abstract Background Recent studies have shown that real-time three-dimensional (3D echocardiography (RT3DE gives more accurate and reproducible left ventricular (LV volume and ejection fraction (EF measurements than traditional two-dimensional methods. A new semi-automated tool (4DLVQ for volume measurements in RT3DE has been developed. We sought to evaluate the accuracy and repeatability of this method compared to a 3D echo standard. Methods LV end-diastolic volumes (EDV, end-systolic volumes (ESV, and EF measured using 4DLVQ were compared with a commercially available semi-automated analysis tool (TomTec 4D LV-Analysis ver. 2.2 in 35 patients. Repeated measurements were performed to investigate inter- and intra-observer variability. Results Average analysis time of the new tool was 141s, significantly shorter than 261s using TomTec (p p = NS, with bias and 95% limits of agreement of 2.1 ± 21 ml, -0.88 ± 17 ml, and 1.6 ± 11% for EDV, ESV, and EF respectively. Intra-observer variability of 4DLVQ vs. TomTec was 7.5 ± 6.2 ml vs. 7.7 ± 7.3 ml for EDV, 5.5 ± 5.6 ml vs. 5.0 ± 5.9 ml for ESV, and 3.0 ± 2.7% vs. 2.1 ± 2.0% for EF (p = NS. The inter-observer variability of 4DLVQ vs. TomTec was 9.0 ± 5.9 ml vs. 17 ± 6.3 ml for EDV (p p p = NS. Conclusion In conclusion, the new analysis tool gives rapid and reproducible measurements of LV volumes and EF, with good agreement compared to another RT3DE volume quantification tool.

    2014-02-01

    The Saturn accelerator, owned by Sandia National Laboratories, has been in operation since the early 1980s and still has many of the original systems. A critical legacy system is the oil transfer system which transfers 250,000 gallons of transformer oil from outside storage tanks to the Saturn facility. The oil transfer system was iden- ti ed for upgrade to current technology standards. Using the existing valves, pumps, and relay controls, the system was automated using the National Instruments cRIO FGPA platform. Engineered safety practices, including a failure mode e ects analysis, were used to develop error handling requirements. The uniqueness of the Saturn Oil Automated Transfer System (SOATS) is in the graphical user interface. The SOATS uses an HTML interface to communicate to the cRIO, creating a platform independent control system. The SOATS was commissioned in April 2013.

    International Nuclear Information System (INIS)

    The purpose of this work is to derive an automated system that provides advantageous drawings of energy spectra for quantum systems (nuclei, atoms, molecules, etc.) required in various physical sciences. The automation involves the development of appropriate computational code and graphical imaging system based on raw data insertion, theoretical calculations and experimental or bibliographic data insertion. The system determines the appropriate scale to depict graphically with the best possible way in the available space. The presently developed code operates locally and the results are displayed on the screen and can be exported to a PostScript file. We note its main features to arrange and visualize in the available space the energy levels with their identity, taking care the existence in the final diagram the least auxiliary deviations. Future improvements can be the use of Java and the availability on the Internet. The work involves the automated plotting of energy levels in molecules, atoms, nuclei and other types of quantized energy spectra.

    In order to succeed in today's global, competitive market, companies need continuous improvements in their product development processes. These improvements should result in expending fewer resources on the design process while achieving better quality. Automating the design process reduces resources needed and allows designers to spend more time on creative aspects that improve the quality of design. For the last three decades, engineers and designers have been searching for better ways to automate the product development process. For certain classes of design problems, which cover a large portion of real world design situations, the process can be automated using knowledge-based systems. These are design problems in which the knowledge sources are known in advance. Using techniques from Knowledge-Based Engineering, knowledge is codified and inserted into a knowledge-based system. The system activates the design knowledge, automatically generating designs that satisfy the design constraints. To increase the return on investment of building automated design systems, Knowledge management methodologies and techniques are required for capturing, formalizing, storing, and searching design knowledge.

  3. Left ventricular diastolic filling in patients with systemic hypertension

    International Nuclear Information System (INIS)

    To study the prevalence and significance of left ventricular (LV) diastolic dysfunction in mild to moderate systemic hypertension (HT), cardiac blood pool imagings with Tc-99 m were obtained in 10 normal subjects and 27 patients with HT. The patients with HT did not show any evidence of coronary heart disease, renal insufficiency, cerebrovascular accident or diabetes mellitus. They were divided into 3 groups; (1) HT-1 (n=10): without evidence of echocardiographic (UCG) and electrocardiographic (ECG) left ventricular hypertrophy (LVH), (2) HT-2 (n=8): with evidence of ECG-LVH without UCG-LVH, (3) HT-3 (n=9): with evidence of UCG-LVH. UCG-LVH was defined when posterior or interventricular septal tall thickness exceeded 13 mm at end-diastole. From UCG findings LV mass was calculated and from UCG findings and auscultating brachial systolic pressure LV peak-systolic wall stress (WS) was obtained. Cardiac blood pool imagings were performed at modified LAO at rest and during exercise stress. Indices of LV systolic function (rest ejection fraction, mean ejection rate during the first third of ejection and exercise ejection fraction response) were essentially similar in normal subjects and all HT groups. In contrast, LV diastolic filling rate during the first third of diastole (1/3 FR mean) decreased significantly in any group of HT, and it was prominent in HT-3. In patients with HT, 1/3 FR mean did not correlate with blood pressure, LV peak-systolic WS, LV systolic functions and LV end-diastolic volume. But it correlated inversely with LV mass (r=-0.84). These results suggest that impairment of early diastolic LV filling can be detected before systolic cardiac impairment and LVH develop, and it is, at least in part, relate to the LV mass. (author)

DESTA is a knowledge-intensive system. The main features of the knowledge are procedures, functions, modules, operating system commands, batch files, their natural language specifications, and their interlinks. The specific domain for the DESTA system is a high level programming language like Turbo Pascal 6.0. The DESTA system is operational and runs on an IBM PC computer.

  8. Intelligent Automated Nuclear Fuel Pellet Inspection System

    International Nuclear Information System (INIS)

    At the present time, nuclear pellet inspection is performed manually using naked eyes for judgment and decisionmaking on accepting or rejecting pellets. This current practice of pellet inspection is tedious and subject to inconsistencies and error. Furthermore, unnecessary re-fabrication of pellets is costly and the presence of low quality pellets in a fuel assembly is unacceptable. To improve the quality control in nuclear fuel fabrication plants, an automated pellet inspection system based on advanced techniques is needed. Such a system addresses the following concerns of the current manual inspection method: (1) the reliability of inspection due to typical human errors, (2) radiation exposure to the workers, and (3) speed of inspection and its economical impact. The goal of this research is to develop an automated nuclear fuel pellet inspection system which is based on pellet video (photographic) images and uses artificial intelligence techniques

    Maaike S M van Mourik

    Full Text Available OBJECTIVE: Monitoring of healthcare-associated infection rates is important for infection control and hospital benchmarking. However, manual surveillance is time-consuming and susceptible to error. The aim was, therefore, to develop a prediction model to retrospectively detect drain-related meningitis (DRM, a frequently occurring nosocomial infection, using routinely collected data from a clinical data warehouse. METHODS: As part of the hospital infection control program, all patients receiving an external ventricular (EVD or lumbar drain (ELD (2004 to 2009; n = 742 had been evaluated for the development of DRM through chart review and standardized diagnostic criteria by infection control staff; this was the reference standard. Children, patients dying <24 hours after drain insertion or with <1 day follow-up and patients with infection at the time of insertion or multiple simultaneous drains were excluded. Logistic regression was used to develop a model predicting the occurrence of DRM. Missing data were imputed using multiple imputation. Bootstrapping was applied to increase generalizability. RESULTS: 537 patients remained after application of exclusion criteria, of which 82 developed DRM (13.5/1000 days at risk. The automated model to detect DRM included the number of drains placed, drain type, blood leukocyte count, C-reactive protein, cerebrospinal fluid leukocyte count and culture result, number of antibiotics started during admission, and empiric antibiotic therapy. Discriminatory power of this model was excellent (area under the ROC curve 0.97. The model achieved 98.8% sensitivity (95% CI 88.0% to 99.9% and specificity of 87.9% (84.6% to 90.8%. Positive and negative predictive values were 56.9% (50.8% to 67.9% and 99.9% (98.6% to 99.9%, respectively. Predicted yearly infection rates concurred with observed infection rates. CONCLUSION: A prediction model based on multi-source data stored in a clinical data warehouse could accurately

    The present study examined the effects of reduced system reliability on operator performance and automation management in an adaptable automation environment. 39 operators were randomly assigned to one of three experimental groups: low (60%), medium (80%), and high (100%) reliability of automation support. The support system provided five incremental levels of automation which operators could freely select according to their needs. After 3 h of training on a simulated process control task (AutoCAMS) in which the automation worked infallibly, operator performance and automation management were measured during a 2.5-h testing session. Trust and workload were also assessed through questionnaires. Results showed that although reduced system reliability resulted in lower levels of trust towards automation, there were no corresponding differences in the operators' reliance on automation. While operators showed overall a noteworthy ability to cope with automation failure, there were, however, decrements in diagnostic speed and prospective memory with lower reliability. PMID:26360226

    Thermal management of the implantable ventricular assist system (VAS) is important not only from the pathophysiological point of view but also from the standpoint of system endurance. The heat distribution within the Baylor VAS was measured using different motor housing materials and environmental conditions. The temperature of the circulating water in the mock loop was set at 37 degrees and 42 degrees C. A polycarbonate motor housing was not a suitable material because of the high temperature development in the actuation system. An anodized aluminum housing demonstrated excellent heat conductivity. The surface temperature of this motor housing was 41.6 degrees C when immersed in circulating water at 42 degrees C. Heat conduction from the motor to the circulating blood revealed an effective thermal path. In the worst case, the heat flux of the motor to the circulating blood revealed an effective thermal path. In the worst case, the heat flux of the motor housing was calculated to be less than 0.062 W/cm2--an acceptable level for the surrounding tissues. PMID:8141658

    The challenge of supplying non-interrupted power from an electrical distribution system experiencing an electrical fault was discussed. Typically, a team of electricians is sent to the fault area to solve the problem. Since this is both time consuming and expensive, a new method called distribution automation system (DAS) has been proposed to address this challenge. The DAS is aimed at low voltage (LV) distribution systems. Under this newly developed DAS, only the consumer where the fault occurs will be affected. The automated system identifies the exact location of the fault and isolates the consumer from the rest of the power distribution system. The consumer will be reconnected to the system only after fault clearance. The system operates and controls the equipment connected at the substation and distribution line/zone/pole remotely. Linking is done by a power line communication (PLC) system with the help of a Remote Control Unit (RTU) and Supervisory Control and Data Acquisition (SCADA) system which improves the ability to monitor various equipment at the substation and at the consumer location. 5 refs., 1 tab., 18 figs.

    Croxatto, A; Prod'hom, G; Faverjon, F; Rochais, Y; Greub, G

    2016-03-01

    Automation was introduced many years ago in several diagnostic disciplines such as chemistry, haematology and molecular biology. The first laboratory automation system for clinical bacteriology was released in 2006, and it rapidly proved its value by increasing productivity, allowing a continuous increase in sample volumes despite limited budgets and personnel shortages. Today, two major manufacturers, BD Kiestra and Copan, are commercializing partial or complete laboratory automation systems for bacteriology. The laboratory automation systems are rapidly evolving to provide improved hardware and software solutions to optimize laboratory efficiency. However, the complex parameters of the laboratory and automation systems must be considered to determine the best system for each given laboratory. We address several topics on laboratory automation that may help clinical bacteriologists to understand the particularities and operative modalities of the different systems. We present (a) a comparison of the engineering and technical features of the various elements composing the two different automated systems currently available, (b) the system workflows of partial and complete laboratory automation, which define the basis for laboratory reorganization required to optimize system efficiency, (c) the concept of digital imaging and telebacteriology, (d) the connectivity of laboratory automation to the laboratory information system, (e) the general advantages and disadvantages as well as the expected impacts provided by laboratory automation and (f) the laboratory data required to conduct a workflow assessment to determine the best configuration of an automated system for the laboratory activities and specificities.

    International Nuclear Information System (INIS)

    The Automated Fuel Element Closure Welding System is a robotic device that will load and weld top end plugs onto nuclear fuel elements in a highly radioactive and inert gas environment. The system was developed at Argonne National Laboratory-West as part of the Fuel Cycle Demonstration. The welding system performs four main functions, it (1) injects a small amount of a xenon/krypton gas mixture into specific fuel elements, and (2) loads tiny end plugs into the tops of fuel element jackets, and (3) welds the end plugs to the element jackets, and (4) performs a dimensional inspection of the pre- and post-welded fuel elements. The system components are modular to facilitate remote replacement of failed parts. The entire system can be operated remotely in manual, semi-automatic, or fully automatic modes using a computer control system. The welding system is currently undergoing software testing and functional checkout

    International Nuclear Information System (INIS)

    Modern automation methods of Optimal Control, or for state reconstruction or parameter identification, require a discrete dynamic path model. This is established among others by time and location discretisation of a system of partial differential equations. The digital wave filter principle is paricularly suitable for this purpose, since the numeric stability of the derived algorithms can be easily guaranteed, and their robustness as to effects of word length limitations can be proven. This principle is also particularly attractive in that it can be excellently integrated into currently existing engineering systems for instrumentation and control. (orig./CB)

  14. Automated statistical modeling of analytical measurement systems

    International Nuclear Information System (INIS)

    The statistical modeling of analytical measurement systems at the Idaho Chemical Processing Plant (ICPP) has been completely automated through computer software. The statistical modeling of analytical measurement systems is one part of a complete quality control program used by the Remote Analytical Laboratory (RAL) at the ICPP. The quality control program is an integration of automated data input, measurement system calibration, database management, and statistical process control. The quality control program and statistical modeling program meet the guidelines set forth by the American Society for Testing Materials and American National Standards Institute. A statistical model is a set of mathematical equations describing any systematic bias inherent in a measurement system and the precision of a measurement system. A statistical model is developed from data generated from the analysis of control standards. Control standards are samples which are made up at precise known levels by an independent laboratory and submitted to the RAL. The RAL analysts who process control standards do not know the values of those control standards. The object behind statistical modeling is to describe real process samples in terms of their bias and precision and, to verify that a measurement system is operating satisfactorily. The processing of control standards gives us this ability

  17. An expert system for automated robotic grasping

    International Nuclear Information System (INIS)

    Many US Department of Energy sites and facilities will be environmentally remediated during the next several decades. A number of the restoration activities (e.g., decontamination and decommissioning of inactive nuclear facilities) can only be carried out by remote means and will be manipulation-intensive tasks. Experience has shown that manipulation tasks are especially slow and fatiguing for the human operator of a remote manipulator. In this paper, the authors present a rule-based expert system for automated, dextrous robotic grasping. This system interprets the features of an object to generate hand shaping and wrist orientation for a robot hand and arm. The system can be used in several different ways to lessen the demands on the human operator of a remote manipulation system - either as a fully autonomous grasping system or one that generates grasping options for a human operator and then automatically carries out the selected option

  18. MDSplus automated build and distribution system

    International Nuclear Information System (INIS)

    Support of the MDSplus data handling system has been enhanced by the addition of an automated build system which does nightly builds of MDSplus for many computer platforms producing software packages which can now be downloaded using a web browser or via package repositories suitable for automatic updating. The build system was implemented using an extensible continuous integration server product called Hudson which schedules software builds on a collection of VMware based virtual machines. New releases are created based on updates via the MDSplus cvs code repository and versioning are managed using cvs tags and branches. Currently stable, beta and alpha releases of MDSplus are maintained for eleven different platforms including Windows, MacOSX, RedHat Enterprise Linux, Fedora, Ubuntu and Solaris. For some of these platforms, MDSplus packaging has been broken into functional modules so users can pick and choose which MDSplus features they want to install. An added feature to the latest Linux based platforms is the use of package dependencies. When installing MDSplus from the package repositories, any additional required packages used by MDSplus will be installed automatically greatly simplifying the installation of MDSplus. This paper will describe the MDSplus package automated build and distribution system

    An automated macromolecular method and system for detecting crystals in two-dimensional images, such as light microscopy images obtained from an array of crystallization screens. Edges are detected from the images by identifying local maxima of a phase congruency-based function associated with each image. The detected edges are segmented into discrete line segments, which are subsequently geometrically evaluated with respect to each other to identify any crystal-like qualities such as, for example, parallel lines, facing each other, similarity in length, and relative proximity. And from the evaluation a determination is made as to whether crystals are present in each image.

    The home automation system concept existed for many years but in the last decade, due to the rapid development of sensors and wireless technologies, a large number of various such "intelligent homes" have been developed. The purpose of the present paper is to demonstrate the flexibility, reliability and affordability of home automation projects, based on a simple and affordable implementation. A wireless sensing and control system have been developed and tested, having a number of basic functionalities such as switching on/off the light according to ambient lighting and turning on/off the central heating. The system has been built around low power microcontrollers and ZigBee modems for wireless communication, using a set of Vishay 640 thermistor sensors for temperature measurements and Vishay LDR07 photo-resistor for humidity measurements. A trigger is activated when the temperature or light measurements are above/below a given threshold and a command is transmitted to the central unit through the ZigBee radio module. All the data processing is performed by a low power microcontroller both at the sensing device and at the control unit.

  5. A control system verifier using automated reasoning software

    International Nuclear Information System (INIS)

    An on-line, automated reasoning software system for verifying the actions of other software or human control systems has been developed. It was demonstrated by verifying the actions of an automated procedure generation system. The verifier uses an interactive theorem prover as its inference engine with the rules included as logical axioms. Operation of the verifier is generally transparent except when the verifier disagrees with the actions of the monitored software. Testing with an automated procedure generation system demonstrates the successful application of automated reasoning software for verification of logical actions in a diverse, redundant manner. A higher degree of confidence may be placed in the verified actions of the combined system

    2004-01-01

    Unlike traditional assembly line robotic systems that have a fixed kinematic structure associated with a single tool for a structured task, next-generation robotic surgical assist systems will be required to use an array of end-effector tools. Once a robot is connected with a tool, the kinematic equations of motion are altered. Given the need to accommodate evolving surgical challenges and to alleviate the restrictions imposed by the confined minimally invasive environment, new surgical tools may resemble small flexible snakes rather than rigid, cable driven instruments. Connecting to these developing articulated tools will significantly alter the overall kinematic structure of a robotic system. In this paper we present a technique for real-time automated generation and evaluation of manipulator kinematic equations that exhibits the combined advantages of existing methods-speed and flexibility to kinematic change--without their disadvantages.

    1984-01-01

    Automation is the application of self-regulating mechanical and electronic devices to processes that can be accomplished with the human organs of perception, decision, and actuation. The successful application of automation to a system process should reduce man/system interaction and the perceived complexity of the system, or should increase affordability, productivity, quality control, and safety. The expense, time constraints, and risk factors associated with extravehicular activities have led the Automation Technology Branch (ATB), as part of the NASA Automation Research and Technology Program, to investigate the use of robots and teleoperators as automation aids in the context of space operations. The ATB program addresses three major areas: (1) basic research in autonomous operations, (2) human factors research on man-machine interfaces with remote systems, and (3) the integration and analysis of automated systems. This paper reviews the current ATB research in the area of robotics and teleoperators.

  10. Automated Root Tracking with "Root System Analyzer"

    Schnepf, Andrea; Jin, Meina; Ockert, Charlotte; Bol, Roland; Leitner, Daniel

    2015-04-01

    Crucial factors for plant development are water and nutrient availability in soils. Thus, root architecture is a main aspect of plant productivity and needs to be accurately considered when describing root processes. Images of root architecture contain a huge amount of information, and image analysis helps to recover parameters describing certain root architectural and morphological traits. The majority of imaging systems for root systems are designed for two-dimensional images, such as RootReader2, GiA Roots, SmartRoot, EZ-Rhizo, and Growscreen, but most of them are semi-automated and involve mouse-clicks in each root by the user. "Root System Analyzer" is a new, fully automated approach for recovering root architectural parameters from two-dimensional images of root systems. Individual roots can still be corrected manually in a user interface if required. The algorithm starts with a sequence of segmented two-dimensional images showing the dynamic development of a root system. For each image, morphological operators are used for skeletonization. Based on this, a graph representation of the root system is created. A dynamic root architecture model helps to determine which edges of the graph belong to an individual root. The algorithm elongates each root at the root tip and simulates growth confined within the already existing graph representation. The increment of root elongation is calculated assuming constant growth. For each root, the algorithm finds all possible paths and elongates the root in the direction of the optimal path. In this way, each edge of the graph is assigned to one or more coherent roots. Image sequences of root systems are handled in such a way that the previous image is used as a starting point for the current image. The algorithm is implemented in a set of Matlab m-files. Output of Root System Analyzer is a data structure that includes for each root an identification number, the branching order, the time of emergence, the parent

  16. Automated Formal Verification for PLC Control Systems

    CERN Multimedia

    Fernández Adiego, Borja

    2014-01-01

    Programmable Logic Controllers (PLCs) are widely used devices used in industrial control systems. Ensuring that the PLC software is compliant with its specification is a challenging task. Formal verification has become a recommended practice to ensure the correctness of the safety-critical software. However, these techniques are still not widely applied in industry due to the complexity of building formal models, which represent the system and the formalization of requirement specifications. We propose a general methodology to perform automated model checking of complex properties expressed in temporal logics (e.g. CTL, LTL) on PLC programs. This methodology is based on an Intermediate Model (IM), meant to transform PLC programs written in any of the languages described in the IEC 61131-3 standard (ST, IL, etc.) to different modeling languages of verification tools. This approach has been applied to CERN PLC programs validating the methodology.

    An automated multi-fluid cooling system and method are provided for cooling an electronic component(s). The cooling system includes a coolant loop, a coolant tank, multiple valves, and a controller. The coolant loop is at least partially exposed to outdoor ambient air temperature(s) during normal operation, and the coolant tank includes first and second reservoirs containing first and second fluids, respectively. The first fluid freezes at a lower temperature than the second, the second fluid has superior cooling properties compared with the first, and the two fluids are soluble. The multiple valves are controllable to selectively couple the first or second fluid into the coolant in the coolant loop, wherein the coolant includes at least the second fluid. The controller automatically controls the valves to vary first fluid concentration level in the coolant loop based on historical, current, or anticipated outdoor air ambient temperature(s) for a time of year.

  18. Left ventricular diastolic filling in elder patients with systemic hypertension

    International Nuclear Information System (INIS)

    To study the significance of left ventricular (LV) diastolic filling in elderly patients with hypertension (HT), cardiac blood pool imagings with Tc-99m were obtained at rest in 17 normal subjects and 28 patients with systemic HT. HT patients did not show any evidence of coronary heart disease, renal insufficiency or other diseases. They showed normal LV ejection fraction (LVEF) and normal LV wall motion. They were divided into 4 groups: normal young (<60 years old, n=10), normal old (≥65 years old, n=7), HT young (<60 years old, N=15), and HT old (≥65 years old, n=13). From the LV volume curve and its first differentiation curve, LVEF, mean first third ejection rate (ERm) and peak ejection rate (PER) were obtained as LV systolic function indices; and LV diastolic filling rate during the first third of diastole (FRm) and peak filling rate (PFR) were obtained as LV diastolic function indices. All indices of LV systolic function were similar in all groups. In contrast, LV diastolic indices (FRm and PFR) of older groups were significantly lower than those of young HT and normal groups. LV diastolic indices in HT groups decreased significantly compared with normal groups of the same age. FRm could distinguish HT patients from normal subjects of the same age more accurately than PFR. In normal subjects, FRm correlated with age (r=-0.490) and ERm (r=-0.489). In addition to age ERm, FRm correlated with LV wall thickness measured by M-mode ecocardiography (r=-0.566) in HT patients. In the HT old group, the correlations between FRm and LV wall thickness and between FRm and ERm were more significant than those in the HT young group. The impairment of early diastolic filling of LV was more prominent in older HT patients than younger HT patients. LV diastolic abnormality was influenced more highly by the degree of LV hypertrophy in older HT patients than younger HT patients. These diastolic abnormalities may cause systolic dysfunction in older HT patients. (J.P.N.)

  19. The Automator: Intelligent control system monitoring

    International Nuclear Information System (INIS)

    A large-scale control system may contain several hundred thousand control points which must be monitored to ensure smooth operation. Knowledge of the current state of such a system is often implicit in the values of these points and operators must be cognizant of the state while making decisions. Repetitive operators requiring human intervention lead to fatigue, which can in turn lead to mistakes. The authors propose a tool called the Automator based on a middleware software server. This tool would provide a user-configurable engine for monitoring control points. Based on the status of these control points, a specified action could be taken. The action could range from setting another control point, to triggering an alarm, to running an executable. Often the data presented by a system is meaningless without context information from other channels. Such a tool could be configured to present interpreted information based on values of other channels. Additionally, this tool could translate numerous values in a non-friendly form (such as numbers, bits, or return codes) into meaningful strings of information. Multiple instances of this server could be run, allowing individuals or groups to configure their own Automators. The configuration of the tool will be file-based. In the future, these files could be generated by graphical design tools, allowing for rapid development of new configurations. In addition, the server will be able to explicitly maintain information about the state of the control system. This state information can be used in decision-making processes and shared with other applications. A conceptual framework and software design for the tool are presented

    In the past control systems for mine hoists have used many technologies including analogue control, relays and static logic. The dramatic advances in technology in recent years now means that all control functions can be performed using a distributed microprocessor system which minimises training, and gives superior diagnostic information, provides very high reliability. The modern distributed microprocessor system covers all the needs of a mine hoist, from advanced control through automation sequencing to safety systems and electronic speed distance protection. The safety core remains as a proven dual line relay system, but is enhanced by comprehensive first up and status monitoring. The advantages of a distributed microprocessor control system are outlined. Details are presented of the proven MWS2000 system as applied to a cycloconvertor winder, and on the range of options available, which includes the elimination of all drum driven auxiliary shafts, cam gear units and mechanical speed distance protection. Special control techniques for deep level hoisting are incorporated in the system, including `S` shaped speed control of emergency mechanical brakes to minimise rope stress. Finally, a review is given of the latest developments in control technology, and the implications for future developments in mine hoisting. 10 figs.

  10. Licensing practices for programmable automation systems

    International Nuclear Information System (INIS)

    The operation and safety automation systems of the new nuclear power plant offered for Finland are proposed to be realized with new programmable digital technology. This seems to be the longest technological leap in the otherwise quite customary plant concepts. In the existing four plant units it may also become necessary to extend or replace old analog systems with digital ones in the future. The safety assessment of a programmable digital system can not be based on conventional probabilistic methods because of the difficulties in quantification of the reliability of the software as well as the hardware. In the case of the software it is widely acknowledged that quantification is difficult. The hardware has equal problems due to the dependence of the effect of a hardware failure on the instruction being executed at the time of failure. The difficulties stem from the complexity, non-continuous behaviour and tendency to common mode failures of the programmable systems. The reliability assessment has to be based on qualitative arguments linked to a claim limit. These qualitative arguments are based on sound engineering judgement and present deterministic as opposed to probabilistic criteria. Due to the uncertainty of the quantitative reliability estimate other means shall be used to gain confidence on the system safety. These means include evidence on the excellence of manufacture supported by deterministic features and confidence building measures. (29 refs., 6 figs., 1 tab.)

  12. System automation for measuring coal combustion efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Ouazzane, K.; Benhadj, R. [London Metropolitan University, London (United Kingdom)

    2006-02-15

    Monitoring the combustion process for electricity generation using coal as a primary resource is of a major concern power generation companies. The carbon content of fly ash is indicative of the combustion efficiency. The determination of this parameter is useful to characterize the efficiency of coal burning furnaces. The main aim of this work is to introduce a new automated system, which can be bolted onto a furnace and work online. The system consists of three main components, namely, a laser instrument for signal acquisition, a neural network tool for training, learning and simulation, and a database system for storage and retrieval. The components have been designed, adapted and tuned for knowledge acquisition of this multi-dimensional problem. When the particles are dispersed across the test space, the instrument observed single particle counts simultaneously on the two photomultipliers. The output voltages displayed represent the intensity of horizontally and vertically polarized light, and the polarization ratio is calculated from the ratio of these voltages. It was found that the carbon-in-ash is related to the polarization ratio and the carbon mass fraction could be determined to within 1 per cent of the carbon content. However, if a proximate analysis is performed on the coal, the prediction could be improved to within 0.05 per cent using neural network simulation. The system has been tested for a range of coal ashes and proved to be efficient.

    2004-01-01

    The Directional Acceleration Vector-Driven Displacement of Fluids (DAVD-DOF) system, under development at the time of reporting the information for this article, would be a relatively compact, automated, centrifugally actuated system for staining blood smears and other microbiological samples on glass microscope slides in either a microgravitational or a normal Earth gravitational environment. The DAVD-DOF concept is a successor to the centrifuge-operated slide stainer (COSS) concept, which was reported in Slide-Staining System for Microgravity or Gravity (MSC-22949), NASA Tech Briefs, Vol. 25, No. 1 (January, 2001), page 64. The COSS includes reservoirs and a staining chamber that contains a microscope slide to which a biological sample is affixed. The staining chamber is sequentially filled with and drained of staining and related liquids from the reservoirs by use of a weighted plunger to force liquid from one reservoir to another at a constant level of hypergravity maintained in a standard swing-bucket centrifuge. In the DAVD-DOF system, a staining chamber containing a sample would also be sequentially filled and emptied, but with important differences. Instead of a simple microscope slide, one would use a special microscope slide on which would be fabricated a network of very small reservoirs and narrow channels connected to a staining chamber (see figure). Unlike in the COSS, displacement of liquid would be effected by use of the weight of the liquid itself, rather than the weight of a plunger.

    2003-08-01

    An automated in-situ road surface distress surveying and management system, AMPIS, has been developed on the basis of video images within the framework of GIS software. Video image processing techniques are introduced to acquire, process and analyze the road surface images obtained from a moving vehicle. ArcGIS platform is used to integrate the routines of image processing and spatial analysis in handling the full-scale metropolitan highway surface distress detection and data fusion/management. This makes it possible to present user-friendly interfaces in GIS and to provide efficient visualizations of surveyed results not only for the use of transportation engineers to manage road surveying documentations, data acquisition, analysis and management, but also for financial officials to plan maintenance and repair programs and further evaluate the socio-economic impacts of highway degradation and deterioration. A review performed in this study on fundamental principle of Pavement Management System (PMS) and its implementation indicates that the proposed approach of using GIS concept and its tools for PMS application will reshape PMS into a new information technology-based system providing a convenient and efficient pavement inspection and management.

    Full Text Available Many software systems have evolved to include a Web-based component that makes them available to the public via the Internet and can expose them to a variety of Web-based attacks. One of these attacks is SQL Injection vulnerability (SQLIV, which can give attackers unrestricted access to the databases that underlie Web applications and has become increasingly frequent and serious. The intent is that Web applications will limit the kinds of queries that can be generated to a safe subset of all possible queries, regardless of what input users provide. SQL Injection attacks are possible due to the design drawbacks of the web sites, which interact with back-end databases. Successful attacks may damage more. We introduce a system that deals with new automated technique for preventing SQLIA based on the novel concept of regular expressions is to detect SQL Injection attacks. The proposed system can detect the attacks that are from Internet and Insider Attacks, by analyzing the packets of the network servers.

    A prototype system for preparing multiple fractions of blood components (plasma, washed red cells, and hemolysates) using automated techniques has been developed. The procedure is based on centrifugal separation and differential pressure-induced transfer in a rotor that has been designed to process numerous samples simultaneously. Red cells are sedimented against the outer walls of the sample chamber, and plasma is syphoned, by imposition of eithr a slight positive or negative pressure, into individual reservoirs in a collection ring. Washing of cells is performed in situ; samples of washed cells, either packed or in saline solution, can be recovered. Cellular hemolysates are prepared and automatically transferred to individual, commercially available collection vials ready for storage in liquid nitrogen or immediate analysis. The system has potential application in any biomedical area which requires high sample throughput and in which one or more of the blood fractions will be used. A separate unit has been designed and developed for the semiautomated cleaning of the blood processing vessel.

    This paper introduces a small unmanned transportation automating system intended to automate production facilities. Small automated guided vehicles (AGV) are available in a small object transporting vehicle and an ultra low floor vehicle. A cylinder head material AGV transports materials from a casting process to an outdoor sand removing process, and the system was demanded to have a single line section and an optimal run to pass each other. Giving and receiving the signals became also necessary with other devices such as existing casting machines and automatic doors. The automotive parts transporting and storing system is a system to assemble parts accommodating buckets in an automatic warehouse, supply the buckets to assembly lines, and return empty buckets to the warehouse. In order to utilize the installation space effectively, the buckets should be moved onto a two-step conveyer, and because the lower conveyer has a part moving height as low as 220 mm above the ground, an ultra low floor AGV was used. Safety measures include a photo sensor to detect obstacles, stoppage of drive at bumper contact, and an area sensor equipped on both sides of the parts moving machine. 9 figs., 4 tabs.

    Full Text Available Fraud is a multi-billion dollar industry that continues to grow annually. Many organisations are poorly prepared to prevent and detect fraud. Fraud detection strategies are intended to quickly and efficiently identify fraudulent activities that circumvent preventative measures. In this paper we adopt a Design-Science methodological framework to develop a model for detection of vendor fraud based on analysis of patterns or signatures identified in enterprise system audit trails. The concept is demonstrated be developing prototype software. Verification of the prototype is achieved by performing a series of experiments. Validation is achieved by independent reviews from auditing practitioners. Key findings of this study are: i automating routine data analytics improves auditor productivity and reduces time taken to identify potential fraud, and ii visualisations assist in promptly identifying potentially fraudulent user activities. The study makes the following contributions: i a model for proactive fraud detection, ii methods for visualising user activities in transaction data, iii a stand-alone MCL-based prototype.

    There are two cyclotrons in operation at IPEN-CNEN/SP: one model CV-28, capable of accelerating p, d, 3He++ and α, with energies of 24, 14, 36 and 28MeV, respectively, and beam currents up to 30μA; the other one, model Cyclone 30, accelerates protons with energy of 30MeV and currents up to 350μA. They have the objective of irradiating targets both for radioisotope production for use in Nuclear Medicine, such as 67Ga, 201Tl, 111In, 123I, 18F and general research. The development of irradiating systems completely automatized was the objective of this work, always aiming to reduce the radiation exposition dose to the workers and to increase the reliability of use of these systems, because very high activities are expected in these processes. In the automation, a Programmable Logical Controller (PLC) was used connected to a feedback net, to manage all the variables involved in the irradiation processes. The program of the PLC was developed using SIMATIC STEP SEVEN (S7), software from SIEMENS, where all the steps are supervised in screens at a microcomputer. The assembling and sequence of leading were developed using the software from UNISOFT, that keeps the operator informed about the work being carried out, at any time. The system is being tested at the CV-28 Cyclotron of IPEN through the irradiations with 24MeV protons and currents up to 10μA in targets of: Solid, natural Zinc electroplated onto a nickelated Copper support for the production of 67Ga; Gas, natural Krypton for the production of the generator 81Rb-81mKr; Liquid, natural water for the production of 18F.

    Mattson, C. B.; Hammond, T. A.; Schwindt, C. J.

    1997-01-01

    The NASA Toxic Vapor Detection Laboratory (TVDL) at the Kennedy Space Center (KSC), Florida, has been using Personal Computer based Data Acquisition and Control Systems (PCDAS) for about nine years. These systems control the generation of toxic vapors of known concentrations under controlled conditions of temperature and humidity. The PCDAS also logs the test conditions and the test article responses in data files for analysis by standard spreadsheets or custom programs. The PCDAS was originally developed to perform standardized qualification and acceptance tests in a search for a commercial off-the-shelf (COTS) toxic vapor detector to replace the hydrazine detectors for the Space Shuttle launch pad. It has since become standard test equipment for the TVDL and is indispensable in producing calibration standards for the new hydrazine monitors at the 10 part per billion (ppb) level. The standard TVDL PCDAS can control two toxic vapor generators (TVG's) with three channels each and two flow/ temperature / humidity (FTH) controllers and it can record data from up to six toxic vapor detectors (TVD's) under test and can deliver flows from 5 to 50 liters per minute (L/m) at temperatures from near zero to 50 degrees Celsius (C) using an environmental chamber to maintain the sample temperature. The concentration range for toxic vapors depends on the permeation source installed in the TVG. The PCDAS can provide closed loop control of temperature and humidity to two sample vessels, typically one for zero gas and one for the standard gas. This is required at very low toxic vapor concentrations to minimize the time required to passivate the sample delivery system. Recently, there have been several requests for information about the PCDAS by other laboratories with similar needs, both on and off KSC. The purpose of this paper is to inform the toxic vapor detection community of the current status and planned upgrades to the automated testing of toxic vapor detectors at the

    1994-01-01

    The expert system called EXADS was developed to aid users of the Automated Design Synthesis (ADS) general purpose optimization program. Because of the general purpose nature of ADS, it is difficult for a nonexpert to select the best choice of strategy, optimizer, and one-dimensional search options from the one hundred or so combinations that are available. EXADS aids engineers in determining the best combination based on their knowledge of the problem and the expert knowledge previously stored by experts who developed ADS. EXADS is a customized application of the AESOP artificial intelligence program (the general version of AESOP is available separately from COSMIC. The ADS program is also available from COSMIC.) The expert system consists of two main components. The knowledge base contains about 200 rules and is divided into three categories: constrained, unconstrained, and constrained treated as unconstrained. The EXADS inference engine is rule-based and makes decisions about a particular situation using hypotheses (potential solutions), rules, and answers to questions drawn from the rule base. EXADS is backward-chaining, that is, it works from hypothesis to facts. The rule base was compiled from sources such as literature searches, ADS documentation, and engineer surveys. EXADS will accept answers such as yes, no, maybe, likely, and don't know, or a certainty factor ranging from 0 to 10. When any hypothesis reaches a confidence level of 90% or more, it is deemed as the best choice and displayed to the user. If no hypothesis is confirmed, the user can examine explanations of why the hypotheses failed to reach the 90% level. The IBM PC version of EXADS is written in IQ-LISP for execution under DOS 2.0 or higher with a central memory requirement of approximately 512K of 8 bit bytes. This program was developed in 1986.

  16. OAP- OFFICE AUTOMATION PILOT GRAPHICS DATABASE SYSTEM

    Science.gov (United States)

    Ackerson, T.

    1994-01-01

    The Office Automation Pilot (OAP) Graphics Database system offers the IBM PC user assistance in producing a wide variety of graphs and charts. OAP uses a convenient database system, called a chartbase, for creating and maintaining data associated with the charts, and twelve different graphics packages are available to the OAP user. Each of the graphics capabilities is accessed in a similar manner. The user chooses creation, revision, or chartbase/slide show maintenance options from an initial menu. The user may then enter or modify data displayed on a graphic chart. The cursor moves through the chart in a "circular" fashion to facilitate data entries and changes. Various "help" functions and on-screen instructions are available to aid the user. The user data is used to generate the graphics portion of the chart. Completed charts may be displayed in monotone or color, printed, plotted, or stored in the chartbase on the IBM PC. Once completed, the charts may be put in a vector format and plotted for color viewgraphs. The twelve graphics capabilities are divided into three groups: Forms, Structured Charts, and Block Diagrams. There are eight Forms available: 1) Bar/Line Charts, 2) Pie Charts, 3) Milestone Charts, 4) Resources Charts, 5) Earned Value Analysis Charts, 6) Progress/Effort Charts, 7) Travel/Training Charts, and 8) Trend Analysis Charts. There are three Structured Charts available: 1) Bullet Charts, 2) Organization Charts, and 3) Work Breakdown Structure (WBS) Charts. The Block Diagram available is an N x N Chart. Each graphics capability supports a chartbase. The OAP graphics database system provides the IBM PC user with an effective means of managing data which is best interpreted as a graphic display. The OAP graphics database system is written in IBM PASCAL 2.0 and assembler for interactive execution on an IBM PC or XT with at least 384K of memory, and a color graphics adapter and monitor. Printed charts require an Epson, IBM, OKIDATA, or HP Laser

    SMART is a uniform automated discrepancy analysis and repair-authoring platform that improves technical accuracy and timely delivery of repair procedures for a given discrepancy (see figure a). SMART will minimize data errors, create uniform repair processes, and enhance the existing knowledge base of engineering repair processes. This innovation is the first tool developed that links the hardware specification requirements with the actual repair methods, sequences, and required equipment. SMART is flexibly designed to be useable by multiple engineering groups requiring decision analysis, and by any work authorization and disposition platform (see figure b). The organizational logic creates the link between specification requirements of the hardware, and specific procedures required to repair discrepancies. The first segment in the SMART process uses a decision analysis tree to define all the permutations between component/ subcomponent/discrepancy/repair on the hardware. The second segment uses a repair matrix to define what the steps and sequences are for any repair defined in the decision tree. This segment also allows for the selection of specific steps from multivariable steps. SMART will also be able to interface with outside databases and to store information from them to be inserted into the repair-procedure document. Some of the steps will be identified as optional, and would only be used based on the location and the current configuration of the hardware. The output from this analysis would be sent to a work authoring system in the form of a predefined sequence of steps containing required actions, tools, parts, materials, certifications, and specific requirements controlling quality, functional requirements, and limitations.

  20. An Automated Flying-Insect Detection System

    Vann, Timi; Andrews, Jane C.; Howell, Dane; Ryan, Robert

    2007-01-01

    An automated flying-insect detection system (AFIDS) was developed as a proof-of-concept instrument for real-time detection and identification of flying insects. This type of system has use in public health and homeland-security decision support, agriculture and military pest management, and/or entomological research. Insects are first lured into the AFIDS integrated sphere by insect attractants. Once inside the sphere, the insect s wing beats cause alterations in light intensity that is detected by a photoelectric sensor. Following detection, the insects are encouraged (with the use of a small fan) to move out of the sphere and into a designated insect trap where they are held for taxonomic identification or serological testing. The acquired electronic wing-beat signatures are preprocessed (Fourier transformed) in real time to display a periodic signal. These signals are sent to the end user where they are graphically. All AFIDS data are preprocessed in the field with the use of a laptop computer equipped with LabVIEW. The AFIDS software can be programmed to run continuously or at specific time intervals when insects are prevalent. A special DC-restored transimpedance amplifier reduces the contributions of low-frequency background light signals, and affords approximately two orders of magnitude greater AC gain than conventional amplifiers. This greatly increases the signal-to-noise ratio and enables the detection of small changes in light intensity. The AFIDS light source consists of high-intensity Al-GaInP light-emitting diodes (LEDs). The AFIDS circuitry minimizes brightness fluctuations in the LEDs and when integrated with an integrating sphere, creates a diffuse uniform light field. The insect wing beats isotropically scatter the diffuse light in the sphere and create wing-beat signatures that are detected by the sensor. This configuration minimizes variations in signal associated with insect flight orientation. Preliminary data indicate that AFIDS has

  3. A hemodynamics model to study the collective behavior of the ventricular-arterial system

    Lin Wang, Yuh-Ying; Wang, Wei-Kung

    2013-01-01

    Applying principles from complex systems to study the efficacy of integrative therapies has become a new interest in medical research. We aimed to construct a concise model for the ventricular-arterial (VA) system and to provide a systematic method for exploring its overall behavior. The transportation of blood from the heart to the peripheral arterioles via hydraulic pressure forces was described by a multi-rank model. Parts of the VA system that have strong mutual interactions were combined into a single sub system. Sub systems of four different ranks were characterized. We then applied the multi-rank model to analyze the aortic pressure wave generated by the periodic ventricular blood ejection, the renal pressure in response to the input from the VA system, and the blood flowing from the renal artery to its arterioles. Maintaining the pressure distribution along the main arteries and in all of the organs with the lowest possible ventricular input turned out to be the first principle for the operation of an efficient VA system. By this principle, we pointed out the benefit of some arterial structures in mammals, derived specific regulation rules and deduced some fundamental concepts for healing. The justification of the biomechanics in our model that differed greatly from those in the prevailing models was given. We concluded that the oscillatory motion and the pressure pulse of the arterial system can be analyzed as steady states with resonance behaviors and suggested utilizing this model to construct integrative therapies for diseases correlated with abnormality in blood circulation.

    International Nuclear Information System (INIS)

    A - Description of program or function: AES (Automated Estimating System) enters and updates the detailed cost, schedule, contingency, and escalation information contained in a typical construction or other project cost estimates. It combines this information to calculate both un-escalated and escalated and cash flow values for the project. These costs can be reported at varying levels of detail. AES differs from previous versions in at least the following ways: The schedule is entered at the WBS-Participant, Activity level - multiple activities can be assigned to each WBS-Participant combination; the spending curve is defined at the schedule activity level and a weighing factor is defined which determines percentage of cost for the WBS-Participant applied to the schedule activity; Schedule by days instead of Fiscal Year/Quarter; Sales Tax is applied at the Line Item Level- a sales tax codes is selected to indicate Material, Large Single Item, or Professional Services; a 'data filter' has been added to allow user to define data the report is to be generated for. B - Method of solution: Average Escalation Rate: The average escalation for a Bill of is calculated in three steps. 1. A table of quarterly escalation factors is calculated based on the base fiscal year and quarter of the project entered in the estimate record and the annual escalation rates entered in the Standard Value File. 2. The percentage distribution of costs by quarter for the Bill of Material is calculated based on the schedule entered and the curve type. 3. The percent in each fiscal year and quarter in the distribution is multiplied by the escalation factor for the fiscal year and quarter. The sum of these results is the average escalation rate for that Bill of Material. Schedule by curve: The allocation of costs to specific time periods is dependent on three inputs, starting schedule date, ending schedule date, and the percentage of costs allocated to each quarter.

    This paper describes a method for automatic contour detection in reformatted short-axis (SA) cardiac computed tomography (CT) using a virtual exploring robot. The robot is a tricycle with a steering front wheel. Its motion obeys a set of kinematic equations and is subject to the non-holonomic constraints. The robot is designed to navigate in the binary representation of a cardiac image, consisting of the allowed navigational and obstacle spaces. It is initially positioned inside the allowed navigational space. Avoiding obstacles, the robot autonomously cruises through the navigational space and collects information about the location of the left ventricular (LV) boundaries. Consequently, the obtained information is used to reconstruct the endocardial and epicardial contours. Validation of the method was performed on in-vivo multislice multiphase short-axis cardiac CT images of ten subjects. Results showed good correlation between the quantitative parameters, computed from manual and automatic segmentation: for end-diastolic volume (EDV) r=0.99, for end-systolic volume (ESV) r=0.98, ejection fraction (EF) r=0.83, and LV mass (LVM) r=0.95.

    This paper introduces automation of loading works in production site by using robots. Loading robots are required of complex movements, and are used for loading work in processing machines requiring six degrees of freedom and for relatively simple palletizing work that can be dealt with by four degrees of freedom. The `inter-machine handling system` is an automated system performed by a ceiling running robot in which different workpiece model determination and positional shift measurement are carried out by image processing. A robot uses the image information to exchange hands automatically as required, and clamp a workpiece; then runs to an M/C to replace the processed workpiece; and put the M/C processes workpiece onto a multi-axial dedicated machine. Five processing machines are operated in parallel with the cycle time matched with that of this handling process, and a processing machine finished of processing is given a handling work in preferential order. As a result, improvement in productivity and elimination of two workers were achieved simultaneously. 6 figs., 5 tabs.

  2. Safeguards and security considerations for automated and robotic systems

    International Nuclear Information System (INIS)

    Within the reconfigured Nuclear Weapons Complex there will be a large number of automated and robotic (A ampersand R) systems because of the many benefits derived from their use. To meet the overall security requirements of a facility, consideration must be given to those systems that handle and process nuclear material. Since automation and robotics is a relatively new technology, not widely applied to the Nuclear Weapons Complex, safeguards and security (S ampersand S) issues related to these systems have not been extensively explored, and no guidance presently exists. The goal of this effort is to help integrate S ampersand S into the design of future A ampersand R systems. Towards this, the authors first examined existing A and R systems from a security perspective to identify areas of concern and possible solutions of these problems. They then were able to develop generalized S ampersand S guidance and design considerations for automation and robotics

    C. TURNER; J. PEHL; ET AL

    2000-12-01

    The introduction of automation systems into many of the facilities dealing with the production, use and disposition of nuclear materials has been an ongoing objective. Many previous attempts have been made, using a variety of monolithic and, in some cases, modular technologies. Many of these attempts were less than successful, owing to the difficulty of the problem, the lack of maturity of the technology, and over optimism about the capabilities of a particular system. Consequently, it is not surprising that suggestions that automation can reduce worker Occupational Radiation Exposure (ORE) levels are often met with skepticism and caution. The development of effective demonstrations of these technologies is of vital importance if automation is to become an acceptable option for nuclear material processing environments. The University of Texas Robotics Research Group (UTRRG) has been pursuing the development of technologies to support modular small automation systems (each of less than 5 degrees-of-freedom) and the design of those systems for more than two decades. Properly designed and implemented, these technologies have a potential to reduce the worker ORE associated with work in nuclear materials processing facilities. Successful development of systems for these applications requires the development of technologies that meet the requirements of the applications. These application requirements form a general set of rules that applicable technologies and approaches need to adhere to, but in and of themselves are generally insufficient for the design of a specific automation system. For the design of an appropriate system, the associated task specifications and relationships need to be defined. These task specifications also provide a means by which appropriate technology demonstrations can be defined. Based on the requirements and specifications of the operations of the Advanced Recovery and Integrated Extraction System (ARIES) pilot line at Los Alamos National

  10. Automated system for crack detection using infrared thermograph

    International Nuclear Information System (INIS)

    The objective of this study was the development of the automated system for crack detection on square steel bars used in the automotive industry for axle and shaft construction. The automated system for thermographic crack detection uses brief pulsed eddy currents to heat steel components under inspection. Cracks, if present, will disturb the current flow and so generate changes in the temperature profile in the crack area. These changes of temperature are visualized using an infrared camera. The image acquired by the infrared camera is evaluated through an image processing system. The advantages afforded by the system are its inspection time, its excellent flaw detection sensitivity and its ability to detect hidden, subsurface cracks. The automated system consists of four IR cameras (each side of steel bar is evaluated at a time), coil, high frequency generator and control place with computers. The system is a part of the inspection line where the subsurface and surface cracks are searched. If the crack is present, the cracked place is automatically marked. The components without cracks are then deposited apart from defective blocks. The system is fully automated and its ability is to evaluate four meter blocks within 20 seconds. This is the real reason for using this system in real industrial applications. (author)

  12. A microcomputerized system of nuclear probe for left ventricular function evaluation

    International Nuclear Information System (INIS)

    In this work, it is presented the development of a system, consisting in a nuclear probe and a 16 bits microcomputer, for left ventricular function (LVF) monitoring and analysis. Previously used in renal and thyroid studies, the nuclear probe, 2''x2''NaI(Tl) crystal, was adapted for its new application. The alterations include the design and construction of appropriate colimators and unterfacing to a strip-chart register and a magnetic tape recorder. After a single injection of Tc-99m labelling red blood cells, the probe is placed over the patient's chest on a convenient left anterior oblique position and a left ventricle time activity curve is obtained. This curve and the patient's eletrocardiogram (ECG) are recorded for posterior processing. The software, in PASCAL language, transfers the data from the magnetic tape to the microcomputer and provides the LVF and ECG curves to be displayed on beat-to-beat mode or as mean curves. From these curves one can extract ventricular parameter such as: ejection fraction, ejection rate, systolic and diastolic intervals and heart rate, by manually positioning three cursors on the points of interest. A critical evaluation of this method is performed and its advantages as well as its limitations are discussed. This approach provides an easy to operate and a low cost device that can be useful in many clinical situations, for example, the continuous monitoring in ICUs, the screening in out-patient departments. The assessment of drugs effects on left ventricular function is also possible. (author)

  13. Traumatic left ventricular aneurysm revealed by systemic embolism. Interest of Indium 111 labelled platelets scintigraphy

    Energy Technology Data Exchange (ETDEWEB)

    1984-01-01

    A case of traumatic left ventricular aneurysm, presenting with recurrent cerebral embolism, 36 years after a thoraco-brachial bullet wound was reported. The 58 year old man had no symptoms of angina or particular cardiovascular risk factors. The ECG showed changes of chronic anterior wall infarction, observed 10 years previously on a routine preoperative recording. There was a calcified circular para-apical shadow on chest X-Ray. The antero-apical region showed hypofixation on myocardial scintigraphy, and hypokinesia on isotopic angiography. The coronary arteries were normal. Indium 111 platelet marking revealed a focus of hyperfixation within the left ventricle. At surgery, a true calcific para-apical left ventricular aneurysm was discovered, containing a fresh thrombus. This lesion was resected. Peroperative Indium 111 platelet test confirmed that the thrombus was the site of high uptake. The surgical result was good at 6 months follow-up. This case illustrates: the value of the Indium test which would appear to be a very specific and sensitive method of detecting intraventricular thrombi. This test, which appreciates the thrombolic activy of intracardiac masses is a useful complement to other non-invasive methods such as 2D echocardiography; the special characteristics of post-trauma left ventricular aneurysms which are rare, often diagnosed late, at the time of complications such as systemic embolism, commonly pose medico-legal problems, and for which surgical treatment seems to be indicated in symptomatic patients.

    Automation was carried out in deburring work using robots in casting and forging processes. With an aluminum cast deburring robot system, a worker sets workpieces on two conveyors alternately, and robot performs processing them sequentially, hence the waiting time for the robot is extremely short. Three kinds of tools are exchanged by an automatic tool changer depending on the condition of burr generation. The system functions also include automatic correction of grinding stones based on measurement of their wear amount, detection of cutting tool breakage, handling irregularly large burrs by means of a tool monitoring unit, and issuing an anomaly alarm upon a worker making a mistake in workpiece selection. The steel cast deburring robot system deals with burrs inside and outside a workpiece by using a process dividing system operated by two robots. The cylinder block deburring robot system works in a line processing system, identifying eight models by using a workpiece model determining machine, and the workpiece models can be changed by a positioning device eliminating the need of set-up works. 4 figs., 4 tabs.

  19. Advanced in In Situ Inspection of Automated Fiber Placement Systems

    Science.gov (United States)

    Juarez, Peter D.; Cramer, K. Elliott; Seebo, Jeffrey P.

    2016-01-01

    Automated Fiber Placement (AFP) systems have been developed to help take advantage of the tailorability of composite structures in aerospace applications. AFP systems allow the repeatable placement of uncured, spool fed, preimpregnated carbon fiber tape (tows) onto substrates in desired thicknesses and orientations. This automated process can incur defects, such as overlapping tow lines, which can severely undermine the structural integrity of the part. Current defect detection and abatement methods are very labor intensive, and still mostly rely on human manual inspection. Proposed is a thermographic in situ inspection technique which monitors tow placement with an on board thermal camera using the preheated substrate as a through transmission heat source. An investigation of the concept is conducted, and preliminary laboratory results are presented. Also included will be a brief overview of other emerging technologies that tackle the same issue.

    Pauls, Jo P; Stevens, Michael C; Bartnikowski, Nicole; Fraser, John F; Gregory, Shaun D; Tansley, Geoff

    2016-08-01

    Rotary left ventricular assist devices (LVADs) show weaker response to preload and greater response to afterload than the native heart. This may lead to ventricular suction or pulmonary congestion, which can be deleterious to the patient's recovery. A physiological control system which optimizes responsiveness of LVADs may reduce adverse events. This study compared eight physiological control systems for LVAD support against constant speed mode. Pulmonary (PVR) and systemic (SVR) vascular resistance changes, a passive postural change and exercise were simulated in a mock circulation loop to evaluate the controller's ability to prevent suction and congestion and to increase exercise capacity. Three active and one passive control systems prevented ventricular suction at high PVR (500 dyne s cm(-5)) and low SVR (600 dyne s cm(-5)) by decreasing LVAD speed (by 200-515 rpm) and by increasing LVAD inflow cannula resistance (up to 1000 dyne s cm(-5)) respectively. These controllers increased LVAD preload sensitivity (to 0.196-2.415 L min(-1) mmHg(-1)) compared to the other control systems and constant speed mode (0.039-0.069 L min(-1) mmHg(-1)). The same three active controllers increased pump speed (600-800 rpm) and thus LVAD flow by 4.5 L min(-1) during exercise which increased exercise capacity. Physiological control systems that prevent adverse events and/or increase exercise capacity may help improve LVAD patient conditions. PMID:26833037

    Arehart, Theodore A.; Carey, Donald O.

    1987-01-01

    The invention is a rotary selectively directional valve assembly for use in an automated turret lathe for directing a stream of high pressure liquid machining coolant to the interface of a machine tool and workpiece for breaking up ribbon-shaped chips during the formation thereof so as to inhibit scratching or other marring of the machined surfaces by these ribbon-shaped chips. The valve assembly is provided by a manifold arrangement having a plurality of circumferentially spaced apart ports each coupled to a machine tool. The manifold is rotatable with the turret when the turret is positioned for alignment of a machine tool in a machining relationship with the workpiece. The manifold is connected to a non-rotational header having a single passageway therethrough which conveys the high pressure coolant to only the port in the manifold which is in registry with the tool disposed in a working relationship with the workpiece. To position the machine tools the turret is rotated and one of the tools is placed in a material-removing relationship of the workpiece. The passageway in the header and one of the ports in the manifold arrangement are then automatically aligned to supply the machining coolant to the machine tool workpiece interface for breaking up of the chips as well as cooling the tool and workpiece during the machining operation.

  6. The design of automated nuclear data systems for industrial application

    International Nuclear Information System (INIS)

    There is a recognized need for on-line monitoring instrumentation that can provide continuous information concerning the distribution of radio-isotopes in nuclear power stations. Consideration of the approach to the design of automated nuclear spectrometry systems for this application provides an example of the operation of complex nuclear data systems in an industrial environment with a requirement for high reliability. Examples of installed systems used for isotopic assay of plant streams and effluents are discussed in some detail. Important considerations in the design of these systems include: (1) automated system energy calibration, (2) verification of system performance, (3) extreme dynamic range, and (4) automated data interpretation to provide plant personnel with information in a form to make operational decisions. High counting rate, front-end electronics developed for this application are described. These systems utilize distributed architecture for optimized through-put and reliability. Trends illustrated in the design of these systems are considered to be applicable for all sophisticated measurement systems which incorporate computer techniques for data acquisition and analysis. The development of diagnostic techniques to insure proper operation of these systems is considered to be essential for field application of measurement systems of increasing complexity. It is anticipated that commercial equipment will be incorporating these techniques in the future. (author)

  17. A Automated Tool for Supporting FMEAs of Digital Systems

    Energy Technology Data Exchange (ETDEWEB)

    Yue,M.; Chu, T.-L.; Martinez-Guridi, G.; Lehner, J.

    2008-09-07

    Although designs of digital systems can be very different from each other, they typically use many of the same types of generic digital components. Determining the impacts of the failure modes of these generic components on a digital system can be used to support development of a reliability model of the system. A novel approach was proposed for such a purpose by decomposing the system into a level of the generic digital components and propagating failure modes to the system level, which generally is time-consuming and difficult to implement. To overcome the associated issues of implementing the proposed FMEA approach, an automated tool for a digital feedwater control system (DFWCS) has been developed in this study. The automated FMEA tool is in nature a simulation platform developed by using or recreating the original source code of the different module software interfaced by input and output variables that represent physical signals exchanged between modules, the system, and the controlled process. For any given failure mode, its impacts on associated signals are determined first and the variables that correspond to these signals are modified accordingly by the simulation. Criteria are also developed, as part of the simulation platform, to determine whether the system has lost its automatic control function, which is defined as a system failure in this study. The conceptual development of the automated FMEA support tool can be generalized and applied to support FMEAs for reliability assessment of complex digital systems.

    1982-09-01

    Provisions for dialogue communication between operating personnel and a computer are of utmost importance in contemporary industrial automated control systems and in automated systems of dispatcher control. The most advanced dialogue systems are the question-answer systems which enable one to communicate with the computer in a language that is close to the natural professional language of the user. This article describes a method for construction of economical question-answer systems which could be realized with the help of minicomputers, and examination of methods for providing such QAs with the expressive capabilities possessed by a natural language. These capabilities include the ambiguity of meanings of words of the input language (polysemy), some elliptic constructions (surpression), and tropeic forms (different forms of metonymy and metaphors). 9 references.

    2010-01-01

    Implantable left ventricular assist devices provide circulatory support for patients at risk of death from refractory, end-stage heart failure. Rotary blood pumps have been designed for increased reliability and smaller size for use in a broader population of patients than the first-generation pulsatile devices. The design concepts and principle of operation of the HeartWare System are discussed. The HeartWare Ventricular Assist System (HVAD) is a small centrifugal flow pump with a displacement volume of 50 ml and an output capacity of 10 L/min. A unique wide-blade impeller is suspended by hybrid passive magnets and hydrodynamic forces. An integrated inflow cannula is inserted into the left ventricle and is held in position by an adjustable sewing ring; the pump is positioned in the pericardial space. The 10-mm outflow graft is anastomosed to the ascending aorta. External system components include the microprocessor-based controller, a monitor, lithium-ion battery packs, alternating current and direct current power adapters, and a battery charger. Physiologic control algorithms are incorporated for safe operation. Preclinical life cycle tests have shown the HVAD to be highly reliable. This system design offers reliability, portability, and ease of use for ambulatory patients. PMID:20559135

The system combines an IBM-developed gantry robot with a special glove box enclosure designed to protect operators and minimize the potential release of tritium to the atmosphere. All hazardous waste handling and processing will be performed remotely, using the robot in a teleoperational mode for one-of-a-kind functions and in an autonomous mode for repetitive operations. Initially, this system will be used in conjunction with a portable gas system designed to capture any gaseous-phase tritium released into the glove box. This paper presents the objectives of this development program, provides background related to LLNL's robotics and waste handling program, describes the major system components, outlines system operation, and discusses current status and plans

    Cholangiocarcinoma, cancer of the bile ducts, is often diagnosed via magnetic resonance cholangiopancreatography (MRCP). Due to low resolution, noise and difficulty is actually seeing the tumor in the images, especially by examining only a single image, there has been very little development of automated systems for cholangiocarcinoma diagnosis. This paper presents a computer-aided diagnosis (CAD) system for the automated preliminary detection of the tumor using a single MRCP image. The multi-stage system employs algorithms and techniques that correspond to the radiological diagnosis characteristics employed by doctors. A popular artificial neural network, the multi-layer perceptron (MLP), is used for decision making to differentiate images with cholangiocarcinoma from those without. The test results achieved was 94% when differentiating only healthy and tumor images, and 88% in a robust multi-disease test where the system had to identify the tumor images from a large set of images containing common biliary diseases.

    In countries where the demand and supply gap of electricity is huge and the people are forced to endure increasing hours of load shedding, unnecessary consumption of electricity makes matters even worse. So the importance and need for electricity conservation increases exponentially. This paper outlines a step towards the conservation of energy in general and electricity in particular by employing efficient Building Automation technique. It should be noted that by careful designing and implementation of the Building Automation System, up to 30% to 40% of energy consumption can be reduced, which makes a huge difference for energy saving. In this study above mentioned concept is verified by performing experiment on a prototype experimental room and by implementing efficient building automation technique. For the sake of this efficient automation, Programmable Logic Controller (PLC) is employed as a main controller, monitoring various system parameters and controlling appliances as per required. The hardware test run and experimental findings further clarifies and proved the concept. The added advantage of this project is that it can be implemented to both small and medium level domestic homes thus greatly reducing the overall unnecessary load on the Utility provider.

    A data management system and method that enables acquisition, integration, and management of real-time data generated at different rates, by multiple heterogeneous incompatible data sources. The system achieves this functionality by using an expert system to fuse data from a variety of airline, airport operations, ramp control, and air traffic control tower sources, to establish and update reference data values for every aircraft surface operation. The system may be configured as a real-time airport surface traffic management system (TMS) that electronically interconnects air traffic control, airline data, and airport operations data to facilitate information sharing and improve taxi queuing. In the TMS operational mode, empirical data shows substantial benefits in ramp operations for airlines, reducing departure taxi times by about one minute per aircraft in operational use, translating as $12 to $15 million per year savings to airlines at the Atlanta, Georgia airport. The data management system and method may also be used for scheduling the movement of multiple vehicles in other applications, such as marine vessels in harbors and ports, trucks or railroad cars in ports or shipping yards, and railroad cars in switching yards. Finally, the data management system and method may be used for managing containers at a shipping dock, stock on a factory floor or in a warehouse, or as a training tool for improving situational awareness of FAA tower controllers, ramp and airport operators, or commercial airline personnel in airfield surface operations.

    Tissue-scale structures such as vessel networks are imaged at micron resolution with the Virtual Tissue System (VT System). VT System imaging of cubic millimeters of tissue and other material extends the capabilities of conventional volumetric techniques such as confocal microscopy, and allows for the first time the integrated 2D and 3D analysis of important tissue structural relationships. The VT System eliminates the need for glass slide-mounted tissue sections and instead captures images directly from the surface of a block containing a sample. Tissues are en bloc stained with fluorochrome compounds, embedded in an optically conditioned polymer that suppresses image signals form dep within the block , and serially sectioned for imaging. Thousands of fully registered 2D images are automatically captured digitally to completely convert tissue samples into blocks of high-resolution information. The resulting multi gigabyte data sets constitute the raw material for precision visualization and analysis. Cellular function may be seen in a larger anatomical context. VT System technology makes tissue metrics, accurate cell enumeration and cell cycle analyses possible while preserving full histologic setting.

  20. ENERGY EFFICIENT AUTOMATED CAR PARKING SYSTEM

    2013-06-01

    Full Text Available Due to a rapid increase in the number of vehicles, the need for parking spaces is on rise. It is important to park the cars in close proximity to avoid traffic congestion and use a parking areaefficiently. Current car parking management systems utilize human personnel to find available parking areas or use a video based system that collects the information in the form of images and tracks available parking slots. This paper describes an alternative energy efficient system which allots a unique parking ‘slot’ for every incoming car. The parking area has a number of ‘slots’ to park which are prioritized in such a way that the available slot nearest to the entry is allotted to every incoming car. The driver has to park in that particular slot allotted without searching for a vacant space thus reducing the time for parking and making an efficient use of available space. The System additionally makes efficient use ofenergy by switching the lights in the parking area ON only when a car is in motion. The application is developed on LPC1343 ARM processor and tested on a miniature prototype. The results suggest that it isa robust system and can be implemented in real time with an option to increase the number of parking slots as required.

    1993-01-01

    This paper presents a signal processing system that: (1) provides an efficient and reliable instrument for investigating the activity of neuronal assemblies in the brain; and (2) demonstrates the feasibility of generating the command signals of prostheses using the activity of relevant neurons in disabled subjects. The system operates online, in a fully automated manner and can recognize the transient waveforms of several neurons in extracellular neurophysiological recordings. Optimal algorithms for detection, classification, and resolution of overlapping waveforms are developed and evaluated. Full automation is made possible by an algorithm that can set appropriate decision thresholds and an algorithm that can generate templates on-line. The system is implemented with a fast IBM PC compatible processor board that allows on-line operation.

  2. Cerebrospinal fluid dynamics in a simplified model of the human ventricular system

    International Nuclear Information System (INIS)

    This study investigates the flow of the Cerebrospinal Fluid (CSF) inside a simplified model of the human ventricular system. Both computational and experimental results are explored. Due to the complexity of the real geometry, a simplified three-dimensional (3-D) model of the ventricular system was constructed with the same volume as the real geometry. The numerical study was conducted using the commercial computational fluid dynamics (CFD) package FLUENT-6. Different CFD cases were solved for different flow rates range between 100-500 ml/day. A scaled up to 4:1 physical model with the same geometry as the computational model, was built. A diluted dye was injected into the physical model and visualized. From the CFD studies it was found that the flow pattern of the CSF is structured and has a 3-D motion. Recirculating motion takes place in the lateral ventricles in the form of small eddies at each plane. Experimentally, the dye reverse motion noticed confirms the CFD findings about the presence of a recirculating motion. (author)

  3. Development of a mobile gammacamera computer system for non invasive ventricular function determination

    International Nuclear Information System (INIS)

    As a reliable non-invasive method, dynamic ventricular volume determination by means of gammacamera computer scintigraphy is now generally accepted to be most useful in clinical cardiology. In view to the fact, however, that the required instrumentation is in general unwieldy and not mobile sophisticated cardiac function studies could not be performed up to now in many intensive care units. In order to overcome this problem we developed a compact scintigraphic system consisting of a mobile gammacamera (Siemens Mobicon) with a conductive build-in minicomputer (Siemens R 20: 16 bit, 128 kB). It renders possible a combined investigation of ventricular volume and pressure. The volume curve is acquired by sequential scintigrahpy whereas the pessure is simultaneously measured manometrically by means of heart catheter. As a result of this comprehensive investigation a pressure-volume loop is plottes the enclosed area of which represents the cardiac work performance. Additionally, functional parameters such as compliance (dV/dp) or stiffness (dp/dV) can be derived from the loop diagram. Besides of the mentioned procedures, the mobile system can also be used for detection of acute infarctions as well as for myocardial scintigraphy in general. (orig.)

    Researchers at the University of Texas at Austin's Biomedical Engineering Laser Laboratory investigating the medical applications of lasers have worked toward the development of a retinal robotic laser system. The ultimate goal of this ongoing project is to precisely place and control the depth of laser lesions for the treatment of various retinal diseases such as diabetic retinopathy and retinal tears. Researchers at the USAF Academy's Department of Electrical Engineering have also become involved with this research due to similar interests. Separate low speed prototype subsystems have been developed to control lesion depth using lesion reflectance feedback parameters and lesion placement using retinal vessels as tracking landmarks. Both subsystems have been successfully demonstrated in vivo on pigmented rabbits using an argon continuous wave laser. Work is ongoing to build a prototype system to simultaneously control lesion depth and placement. The instrumentation aspects of the prototype subsystems were presented at SPIE Conference 1877 in January 1993. Since then our efforts have concentrated on combining the lesion depth control subsystem and the lesion placement subsystem into a single prototype capable of simultaneously controlling both parameters. We have designed this combined system CALOSOS for Computer Aided Laser Optics System for Ophthalmic Surgery. An initial CALOSOS prototype design is provided. We have also investigated methods to improve system response time. The use of high speed non-standard frame rate CCD cameras and high speed local bus frame grabbers hosted on personal computers are being investigated. A review of system testing in vivo to date is provided in SPIE Conference proceedings 2374-49 (Novel Applications of Lasers and Pulsed Power, Dual-Use Applications of Lasers: Medical session).

    The wireless drive of an automated implantable electronic sensor has been explored for health monitoring applications. The proposed system comprises of an automated biomedical sensing system which is energized through resonant inductive coupling. The implantable sensor unit is able to monitor the body temperature parameter and sends back the corresponding telemetry data wirelessly to the data recoding unit. It has been observed that the wireless power delivery system is capable of energizing the automated biomedical implantable electronic sensor placed over a distance of 3 cm from the power transmitter with an energy transfer efficiency of 26% at the operating resonant frequency of 562 kHz. This proposed method ensures real-time monitoring of different human body temperatures around the clock. The monitored temperature data have been compared with a calibrated temperature measurement system to ascertain the accuracy of the proposed system. The investigated technique can also be useful for monitoring other body parameters such as blood pressure, bladder pressure, and physiological signals of the patient in vivo using various implantable sensors.

  16. Intelligent Computer Vision System for Automated Classification

    International Nuclear Information System (INIS)

    In this paper we investigate an Intelligent Computer Vision System applied for recognition and classification of commercially available cork tiles. The system is capable of acquiring and processing gray images using several feature generation and analysis techniques. Its functionality includes image acquisition, feature extraction and preprocessing, and feature classification with neural networks (NN). We also discuss system test and validation results from the recognition and classification tasks. The system investigation also includes statistical feature processing (features number and dimensionality reduction techniques) and classifier design (NN architecture, target coding, learning complexity and performance, and training with our own metaheuristic optimization method). The NNs trained with our genetic low-discrepancy search method (GLPτS) for global optimisation demonstrated very good generalisation abilities. In our view, the reported testing success rate of up to 95% is due to several factors: combination of feature generation techniques; application of Analysis of Variance (ANOVA) and Principal Component Analysis (PCA), which appeared to be very efficient for preprocessing the data; and use of suitable NN design and learning method.

  19. A portable, automated, inexpensive mass and balance calibration system

    International Nuclear Information System (INIS)

    Reliable mass measurements are essential for a nuclear production facility or process control laboratory. DOE Order 5630.2 requires that traceable standards be used to calibrate and monitor equipment used for nuclear material measurements. To ensure the reliability of mass measurements and to comply with DOE traceability requirements, a portable, automated mass and balance calibration system is used at the Savannah River Plant. Automation is achieved using an EPSON HX-20 notebook computer, which can be operated via RS232C interfacing to electronic balances or function with manual data entry if computer interfacing is not feasible. This economical, comprehensive, user-friendly system has three main functions in a mass measurement control program (MMCP): balance certification, calibration of mass standards, and daily measurement of traceable standards. The balance certification program tests for accuracy, precision, sensitivity, linearity, and cornerloading versus specific requirements. The mass calibration program allows rapid calibration of inexpensive mass standards traceable to certified Class S standards. This MMCP permits daily measurement of traceable standards to monitor the reliability of balances during routine use. The automated system verifies balance calibration, stores results for future use, and provides a printed control chart of the stored data. Another feature of the system permits three different weighing routines that accommodate their need for varying degrees of reliability in routine weighing operations

    Science.gov (United States)

    Juarez, Peter D.; Cramer, K. Elliott; Seebo, Jeffrey P.

    2016-05-01

    Automated Fiber Placement (AFP) systems have been developed to help take advantage of the tailorability of composite structures in aerospace applications. AFP systems allow the repeatable placement of uncured, spool fed, preimpregnated carbon fiber tape (tows) onto substrates in desired thicknesses and orientations. This automated process can incur defects, such as overlapping tow lines, which can severely undermine the structural integrity of the part. Current defect detection and abatement methods are very labor intensive, and still mostly rely on human manual inspection. Proposed is a thermographic in situ inspection technique which monitors tow placement with an on board thermal camera using the preheated substrate as a through transmission heat source. An investigation of the concept is conducted, and preliminary laboratory results are presented. Also included will be a brief overview of other emerging technologies that tackle the same issue.

  4. Automated data system for emergency meteorological response

    International Nuclear Information System (INIS)

    The Savannah River Plant (SRP) releases small amounts of radioactive nuclides to the atmosphere as a consequence of the production of radioisotopes. To provide for emergency meteorological response to accidental releases and to conduct research on the transport and diffusion of radioactive nuclides in the routine releases, a series of high-quality meteorological sensors have been located on towers in and about SRP. These towers are equipped with instrumentation to detect and record temperature and wind turbulence. Signals from the meteorological sensors are brought by land-line to the SRL Weather Center-Analysis Laboratory (WC--AL). At the WC--AL, a Weather Information and Display (WIND) system has been installed. The WIND system consists of a minicomputer with graphical displays in the WC--AL and also in the emergency operating center (EOC) of SRP. Should there be an accidental release to the atmosphere, available recorded data and computer codes would allow the calculation and display of the location, time, and downwind concentration of the atmospheric release. These data are made available to decision makers in near real-time to permit rapid decisive action to limit the consequences of such accidental releases

  5. Developments in control systems for rotary left ventricular assist devices for heart failure patients: a review

    International Nuclear Information System (INIS)

    From the moment of creation to the moment of death, the heart works tirelessly to circulate blood, being a critical organ to sustain life. As a non-stopping pumping machine, it operates continuously to pump blood through our bodies to supply all cells with oxygen and necessary nutrients. When the heart fails, the supplement of blood to the body's organs to meet metabolic demands will deteriorate. The treatment of the participating causes is the ideal approach to treat heart failure (HF). As this often cannot be done effectively, the medical management of HF is a difficult challenge. Implantable rotary blood pumps (IRBPs) have the potential to become a viable long-term treatment option for bridging to heart transplantation or destination therapy. This increases the potential for the patients to leave the hospital and resume normal lives. Control of IRBPs is one of the most important design goals in providing long-term alternative treatment for HF patients. Over the years, many control algorithms including invasive and non-invasive techniques have been developed in the hope of physiologically and adaptively controlling left ventricular assist devices and thus avoiding such undesired pumping states as left ventricular collapse caused by suction. In this paper, we aim to provide a comprehensive review of the developments of control systems and techniques that have been applied to control IRBPs. (topical review)

    2005-04-01

    Non-Destructive Testing is necessary in areas where defects in structures emerge over time due to wear and tear and structural integrity is necessary to maintain its usability. However, manual testing results in many limitations: high training cost, long training procedure, and worse, the inconsistent test results. A prime objective of this project is to develop an automatic Non-Destructive testing system for a shaft of the wheel axle of a railway carriage. Various methods, such as the neural network, pattern recognition methods and knowledge-based system are used for the artificial intelligence problem. In this paper, a statistical pattern recognition approach, Classification Tree is applied. Before feature selection, a thorough study on the ultrasonic signals produced was carried out. Based on the analysis of the ultrasonic signals, three signal processing methods were developed to enhance the ultrasonic signals: Cross-Correlation, Zero-Phase filter and Averaging. The target of this step is to reduce the noise and make the signal character more distinguishable. Four features: 1. The Auto Regressive Model Coefficients. 2. Standard Deviation. 3. Pearson Correlation 4. Dispersion Uniformity Degree are selected. And then a Classification Tree is created and applied to recognize the peak positions and amplitudes. Searching local maximum is carried out before feature computing. This procedure reduces much computation time in the real-time testing. Based on this algorithm, a software package called SOFRA was developed to recognize the peaks, calibrate automatically and test a simulated shaft automatically. The automatic calibration procedure and the automatic shaft testing procedure are developed.

    2013-09-01

    Full Text Available In the field of agriculture, use of proper method of irrigation is important because the main reason is the lack of rains {&} scarcity of land reservoir water. The continuous extraction of water from earth is reducing the water level due to which lot of land is coming slowly in the zones of un-irrigated land. Another very important reason of this is due to unplanned use of water due to which a significant amount of water goes waste. For this purpose; we use this automatic plant irrigation system. In this project we use solar energy which is used to operate the irrigation pump. The circuit comprises of sensor parts built using op-amp IC LM358. Op-amp are configured here as a comparator. Two stiff copper wires are inserted in the soil to sense whether the soil is wet or dry. The Microcontroller is used to control the whole system by monitoring the sensors and when sensors sense the dry condition then the microcontroller will send command to relay driver IC the contacts of which are used to switch on the motor and it will switch off the motor when all the sensors are in wet condition. The microcontroller does the above job as it receives the signal from the sensors through the output of the comparator, and these signals operate under the control of software which is stored in ROM of the Microcontroller. The condition of the pump i.e., ON/OFF is displayed on a 16X2 LCD

    Full Text Available In this study, manually (paperwork and periodically prepared exam scheduling applications at universities have been taken into a computer automation system by developing a software solution. In the software developed by the authors, Evolutionary Algorithm method has been applied and university administration's specific improvement requests have also been taken into consideration while developing the software. The developed software has two parts: First part is about collecting data through the web application, and the second part is the application project, which calculates the final scheduling results. By utilizing the software, a considerable amount of time lost by manually preparing exam schedules will be saved. In addition, with the real-time connection to the student automation system database, numerous problems will be vanished, i.e. students/classes exam scheduling conflicts, etc. In the study, tables added to the current student automation system database have been explained. Additionally, by applying the genetic algorithm methods to the various parts of data have been examined along with the constraints used in the application, which are essential parts of the software. User interfaces have been designed with their sample instances. Finally, exam-scheduling table has been created and an example output of the schedule has been generated in the study.

  17. Improving CBIR Systems Using Automated Ranking

    2012-11-01

    Full Text Available The most common way of searching images on the Internet and in private collections is based on a similarity measuring of a series of text words that are assigned to each image with users query series. This method imposes strong constraints (the number of words to describe the image, the time necessary to thoroughly describe the subjective experience of images, the level of details in the picture, language barrier, etc., and is therefore very inefficient. Modern researches in this area are focused on the contentbased searching images (CBIR. In this way, all described disadvantages are overcome and the quality of searching results is improved. This paper presents a solution for CBIR systems where the search procedure is enhanced using sophisticated extraction and ranking of extracted images. The searching procedure is based on extraction and preprocessing of a large number of low level image features. Thus, when the user defines a query image, the proposed algorithm based on artificial intelligence, shows to the user a group of images which are most similar to a query image by content. The proposed algorithm is iterative, so the user can direct the searching procedure to an expected outcome and get a set of images that are more similar to the query one.

    Automated trading systems on developed and emerging capital markets are studied in this paper. The standard for developed market is automated trading system with 40-days simple moving average. We tested it for the index SIX Industrial for 1000 and 730 trading days of the slovak emerging capital market. The Buy and Hold trading system was 7.80 times more profitable than this etalon trading system for active trading. Taking of profitable standard trading system from a developed capital market does not lead to optimal results on the emerging capital markets. We then studied optimized standard trading system based on the simple moving average. The parameter of optimization was the number of weeks. An optimal system was that with 5 weeks. This trading system has some of its characteristics comparable with the etalon trading system on the NYSE Composite Index. The emerging market is more risky than the developed market. The profit on the emerging market is also higher. The range of optimized system parameter is qui...

  19. Monitoring of right ventricular function by single probe system (nuclear stethoscope) and sup(81m)Kr

    International Nuclear Information System (INIS)

    A single probe system (nuclear stethoscope) was developed to evaluate the monitoring of right ventricular function by sup(81m)Kr continuous infusion method. Optimal right ventricular and background positions were determined by position/monitor mode on beat-to-beat basis, and right ventricular ejection fraction (RVEF) was calculated by multi-gated method (MUGA). The correlation coefficient of nuclear stethoscope RVEF and camera-computer RVEF (MUGA) was 0.82, while the correlation coefficient of nuclear stethoscope RVEF and camera-computer RVEF (first-pass method) was 0.64. Therefore, the RVEF by nuclear stethoscope is useful for monitoring of right ventricular function. Clinical applications by sup(81m)Kr and nuclear stethoscope were as follows. 1. Exercise/rest RVEF is an extremely sensitive indicator to discriminate coronary artery disease (RCA occlusion) from normal subjects. 2. Beat-to-beat right ventricular volume response is useful for the monitoring of arrythmia such as atrial fibrillation. (author)

  1. Diversity requirements for safety critical software-based automation systems

    International Nuclear Information System (INIS)

    System vendors nowadays propose software-based systems even for the most critical safety functions in nuclear power plants. Due to the nature and mechanisms of influence of software faults new methods are needed for the safety and reliability evaluation of these systems. In the research project 'Programmable automation systems in nuclear power plants (OHA)' various safety assessment methods and tools for software based systems are developed and evaluated. This report first discusses the (common cause) failure mechanisms in software-based systems, then defines fault-tolerant system architectures to avoid common cause failures, then studies the various alternatives to apply diversity and their influence on system reliability. Finally, a method for the assessment of diversity is described. Other recently published reports in OHA-report series handles the statistical reliability assessment of software based (STUK-YTO-TR 119), usage models in reliability assessment of software-based systems (STUK-YTO-TR 128) and handling of programmable automation in plant PSA-studies (STUK-YTO-TR 129)

    1990-01-01

    Ways in which computers can aid the decision making of an human operator of an aerospace system are investigated. The approach taken is to aid rather than replace the human operator, because operational experience has shown that humans can enhance the effectiveness of systems. As systems become more automated, the role of the operator has shifted to that of a manager and problem solver. This shift has created the research area of how to aid the human in this role. Published research in four areas is described. A discussion is presented of the DC-8 flight simulator at Georgia Tech.

    Cerebrospinal fluid (CSF) is a Newtonian fluid and can, therefore, be modelled using computational fluid dynamics (CFD). Previous modelling of the CSF has been limited to simplified geometric models. This work describes a geometrically accurate three dimensional (3D) computational model of the human ventricular system (HVS) constructed from magnetic resonance images (MRI) of the human brain. It is an accurate and full representation of the HVS and includes appropriately positioned CSF production and drainage locations. It was used to investigate the pulsatile motion of CSF within the human brain. During this investigation CSF flow rate was set at a constant 500 ml/day, to mimic real life secretion of CSF into the system, and a pulsing velocity profile was added to the inlets to incorporate the effect of cardiac pulsations on the choroid plexus and their subsequent influence on CSF motion in the HVS. Boundary conditions for the CSF exits from the ventricles (foramina of Magendie and Lushka) were found using a "nesting" approach, in which a simplified model of the entire central nervous system (CNS) was used to examine the effects of the CSF surrounding the ventricular system (VS). This model provided time varying pressure data for the exits from the VS nested within it. The fastest flow was found in the cerebral aqueduct, where a maximum velocity of 11.38 mm/s was observed over five cycles. The maximum Reynolds number recorded during the simulation was 15 with an average Reynolds number of the order of 0.39, indicating that CSF motion is creeping flow in most of the computational domain and consequently will follow the geometry of the model. CSF pressure also varies with geometry with a maximum pressure drop of 1.14 Pa occurring through the cerebral aqueduct. CSF flow velocity is substantially slower in the areas that are furthest away from the inlets; in some areas flow is nearly stagnant. PMID:18297492

    Non-Tf-bound iron (NTBI), which appears in serum in iron overload, is thought to contribute to organ damage; the monitoring of serum NTBI levels may therefore be clinically useful in iron-overloaded patients. However, NTBI quantification methods remain complex, limiting their use in clinical practice. To overcome the technical difficulties often encountered, we recently developed a novel automated NTBI quantification system capable of measuring large numbers of samples. In the present study, we investigated the in vivo behavior of NTBI in human and animal serum using this newly established automated system. Average NTBI in healthy volunteers was 0.44 ± 0.076 μM (median 0.45 μM, range 0.28-0.66 μM), with no significant difference between sexes. Additionally, serum NTBI rapidly increased after iron loading, followed by a sudden disappearance. NTBI levels also decreased in inflammation. The results indicate that NTBI is a unique marker of iron metabolism, unlike other markers of iron metabolism, such as serum ferritin. Our new automated NTBI quantification method may help to reveal the clinical significance of NTBI and contribute to our understanding of iron overload. PMID:27086349

    To evaluate automated segmentation and the effects of different manual adjustments regarding left ventricular parameter quantification in cardiac magnetic resonance (MR) data on children and adolescents who have undergone surgical repair of right-sided congenital heart disease (CHD). Dedicated software (syngo.via, Siemens AG) was used to automatically segment and/or manually adjust the end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), myocardial mass (MM) and ejection fraction (EF) before/after manual apex/base adjustment (ADJ-step 1) and after manual apex/base/myocardial contour adjustment (ADJ-step 2; reference standard). MR data of 40 patients (13.1 ± 3.1y, 4-17y) with repaired CHD with decreased pulmonary blood flow (CHD-DPBF) were evaluated. Intra- and inter-rater reliability was determined for 10 randomly selected patients. The software correctly detected the left ventricle in 38/40 (95 %) patients. EDV after automated segmentation: 119.1 ± 44.0ml; after ADJ-step 1: 115.8 ± 39.5 ml; after ADJ-step 2: 116.2 ± 39.4 ml. The corresponding results for ESV were 52.0 ± 18.5/49.6 ± 16.9/49.7 ± 16.4 ml; for SV 67.1 ± 28.5/66.2 ± 25.4/66.5 ± 25.5 ml; for EF 55.5 ± 7.3/56.7 ± 6.6/56.7 ± 6.3%; for MM 83.7 ± 35.9/76.2 ± 28.3/74.6 ± 27.2 g. Significant differences were found for ESV/MM/EF comparing the automated segmentation results with these after ADJ-step 1 and ADJ-step 2. No significant differences were found when comparing all results of ADJ-step 1 and ADJ-step 2 or when comparing EDV/SV results. Intra- and inter-rater reliability was excellent. The mean time effort was 63.4 ± 6.9 s for the automated segmentation, 74.2 ± 8.9 s for ADJ-step 1 and 269.5 ± 39.4 s for ADJ-step 2.

    Full Text Available In today’s techno savvy world, automated system is very important and contemporary issue. Automated systems are widely used at industries, appliance, automobile, undersea, space and healthcare over the past decade. The accuracy of Robots makes any system more acceptable. Here we use the Robots which assist us to manage patient’s heath. We always expect the system must work under any situation. The development of Robotic software is a complex and error prone process. Most complex systems contain software, and systems failures activated by software faults can provide lessons for software development practices and software quality assurance. They must be identified and removed as early as possible. The interrelationship between software faults and failures is quite intricate and obtaining a meaningful characterization. Towards this characterization, we have investigated and classified failures observed in Robotic system. In this paper, we describe the process used in our study for tracking faults. We present the different types of faults, their impact and fault classification. The concern thing is Faults classification and proposed way to manage them. Then we propose the fault tolerance techniques as single to covenant with different faults

    2003-03-01

    A proposal submitted to the U.S. Department of Energy (DOE), Office of Science and Technology, Accelerated Site Technology Deployment (ASTD) program to deploy an automated monitoring system for waste disposal sites and groundwater, herein referred to as the ''Automated Monitoring System,'' was funded in fiscal year (FY) 2002. This two-year project included three parts: (1) deployment of cellular telephone modems on existing dataloggers, (2) development of a data management system, and (3) development of Internet accessibility. The proposed concept was initially (in FY 2002) to deploy cellular telephone modems on existing dataloggers and partially develop the data management system at the Nevada Test Site (NTS). This initial effort included both Bechtel Nevada (BN) and the Desert Research Institute (DRI). The following year (FY 2003), cellular modems were to be similarly deployed at Sandia National Laboratories (SNL) and Los Alamos National Laboratory (LANL), and the early data management system developed at the NTS was to be brought to those locations for site-specific development and use. Also in FY 2003, additional site-specific development of the complete system was to be conducted at the NTS. To complete the project, certain data, depending on site-specific conditions or restrictions involving distribution of data, were to made available through the Internet via the DRI/Western Region Climate Center (WRCC) WEABASE platform. If the complete project had been implemented, the system schematic would have looked like the figure on the following page.

    Avoidance of poorly installed HVAC systems is best accomplished at the close of construction by having a building and its systems put ''through their paces'' with a well conducted commissioning process. This research project focused on developing key components to enable the development of tools that will automatically detect and correct equipment operating problems, thus providing continuous and automatic commissioning of the HVAC systems throughout the life of a facility. A study of pervasive operating problems reveled the following would most benefit from an automated and continuous commissioning process: (1) faulty economizer operation; (2) malfunctioning sensors; (3) malfunctioning valves and dampers, and (4) access to project design data. Methodologies for detecting system operation faults in these areas were developed and validated in ''bare-bones'' forms within standard software such as spreadsheets, databases, statistical or mathematical packages. Demonstrations included flow diagrams and simplified mock-up applications. Techniques to manage data were demonstrated by illustrating how test forms could be populated with original design information and the recommended sequence of operation for equipment systems. Proposed tools would use measured data, design data, and equipment operating parameters to diagnosis system problems. Steps for future research are suggested to help more toward practical application of automated commissioning and its high potential to improve equipment availability, increase occupant comfort, and extend the life of system equipment.

  13. Optimal deadlock avoidance Petri net supervisors for automated manufacturing systems

    Keyi XING; Feng TIAN; Xiaojun YANG

    2007-01-01

    Deadlock avoidance problems are investigated for automated manufacturing systems with flexible routings.Based on the Petri net models of the systems, this paper proposes, for the first time, the concept of perfect maximal resourcetransition circuits and their saturated states. The concept facilitates the development of system liveness characterization and deadlock avoidance Petri net supervisors. Deadlock is characterized as some perfect maximal resource-transition circuits reaching their saturated states. For a large class of manufacturing systems, which do not contain center resources, the optimal deadlock avoidance Petri net supervisors are presented. For a general manufacturing system, a method is proposed for reducing the system Petri net model so that the reduced model does not contain center resources and, hence, has optimal deadlock avoidance Petri net supervisor. The controlled reduced Petri net model can then be used as the liveness supervisor of the system.

    Full Text Available A 64-year-old female was diagnosed with systemic amyloidosis associated with multiple myeloma. Bortezomib and dexamethasone-therapy was initiated; however, she developed lethal ventricular fibrillation (VF and cardiac arrest after 84 hours of therapy. Cardiopulmonary resuscitation using direct current shocks with epinephrine and amiodarone was initiated but failed to receive cardiac function. Although her arterial pulsations recovered immediately after the injection of vasopressin, she died of heart failure 8 hours after the onset of VF. Cardiac amyloidosis was verified by autopsy. Although the direct association of bortezomib with lethal VF remained to be clarified in our patient, the current report emphasizes on bortezomib as a substantial risk factor for cardiomyocyte damage. The potential risk of lethal events associated with cardiac amyloidosis should be carefully considered during bortezomib treatment for patients with AL amyloidosis.

    A new graphitisation system, directly coupled to an elemental analyser, has been developed for convenient, fast and efficient sample preparations for radiocarbon measurement by means of accelerator mass spectrometry. We demonstrate an alternative to the cryogenic transport of CO{sub 2} into the graphitisation reactors with liquid nitrogen, which is used by others. Instead, the CO{sub 2} coming from an EA is absorbed on a single column filled with zeolite. The CO{sub 2} can then be easily released by heating the zeolite trap and transferred to the reactor by gas expansion. The system is simple and fully automated for sample combustion and graphitisation.

    AlliedSignal Federal Manufacturing & Technologies (FM&T) was asked to perform a proof-of-concept study for the Missouri Highway and Transportation Department (MHTD), Research Division, in June 1997. The goal of this proof-of-concept study was to ascertain if automated scanning and imaging techniques might be applied effectively to the problem of concrete evaluation. In the current evaluation process, a concrete sample core is manually scanned under a microscope. Voids (or air spaces) within the concrete are then detected visually by a human operator by incrementing the sample under the cross-hairs of a microscope and by counting the number of "pixels" which fall within a void. Automation of the scanning and image analysis processes is desired to improve the speed of the scanning process, to improve evaluation consistency, and to reduce operator fatigue. An initial, proof-of-concept image analysis approach was successfully developed and demonstrated using acquired black and white imagery of concrete samples. In this paper, the automated scanning and image capture system currently under development will be described and the image processing approach developed for the proof-of-concept study will be demonstrated. A development update and plans for future enhancements are also presented.

    Full Text Available Objective(s: Peptide Receptor Radionuclide Therapy (PRRT with yttrium-90 (90Y and lutetium-177 (177Lu-labelled SST analogues are now therapy option for patients who have failed to respond to conventional medical therapy. In-house production with automated PRRT synthesis systems have clear advantages over manual methods resulting in increasing use in hospital-based radiopharmacies. We report on our one year experience with an automated radiopharmaceutical synthesis system.Methods: All syntheses were carried out using the Eckert & Ziegler Eurotope’s Modular-Lab Pharm Tracer® automated synthesis system. All materials and methods used were followed as instructed by the manufacturer of the system (Eckert & Ziegler Eurotope, Berlin, Germany. Sterile, GMP-certified, no-carrier added (NCA 177Lu was used with GMPcertifiedpeptide. An audit trail was also produced and saved by the system. The quality of the final product was assessed after each synthesis by ITLCSG and HPLC methods.Results: A total of 17 [177Lu]-DOTATATE syntheses were performed between August 2013 and December 2014. The amount of radioactive [177Lu]-DOTATATE produced by each synthesis varied between 10-40 GBq and was dependant on the number of patients being treated on a given day. Thirteen individuals received a total of 37 individual treatment administrations in this period. There were no issues and failures with the system or the synthesis cassettes. The average radiochemical purity as determined by ITLC was above 99% (99.8 ± 0.05% and the average radiochemical purity as determined by HPLC technique was above 97% (97.3 ± 1.5% for this period.Conclusions: The automated synthesis of [177Lu]-DOTATATE using Eckert & Ziegler Eurotope’s Modular-Lab Pharm Tracer® system is a robust, convenient and high yield approach to the radiolabelling of DOTATATE peptide benefiting from the use of NCA 177Lu and almost negligible radiation exposure of the operators.

  4. A passive automated personnel accountability system for reactor emergency preparedness

    International Nuclear Information System (INIS)

    In 1985 a project was undertaken at the N Reactor on the Hanford Site to develop an automated personnel accountability system to ensure accountability of all personnel within 30 minutes of a site evacuation. The decision to develop such a system was made after a full-scale evacuation drill showed that the manual accountability system in use at the time was inadequate to meet the 30-minute requirement. Accountability systems at commercial nuclear power plants were evaluated, but found to be unsuitable because they were not passive, that is, they required action on part of the user for the system to work. Approximately 2500 people could be required to evacuate the 100-N Area. Therefore, a card key system or badge exchange system was judged not to be feasible. A passive accountability system was desired for N Reactor to allow personnel to enter and leave the site in a more timely manner. To meet the need for an automated accountability system at N Reactor, a special Evacuation Accountability System (EVACS) was designed and developed. The EVACS system has three basic components: the transponder, a credit card-sized device worn with the security badge; portal monitors, which are electronically activated by the transponder; and a computer information system that contains the personnel data base. Each person wearing a transponder is accounted for automatically by walking through a portal. In this paper, a description of the hardware and software will be presented, together with problems encountered and lessons learned while adapting an existing technology to this particular use. The system is currently installed and requires acceptance testing before becoming operational

    There have been many studies to detect infectious diseases with the molecular genetic method. This study presents an automation process for a DNA extraction system based on microfluidics and magnetic bead, which is part of a portable molecular genetic test system. This DNA extraction system consists of a cartridge with chambers, syringes, four linear stepper actuators, and a rotary stepper actuator. The actuators provide a sequence of steps in the DNA extraction process, such as transporting, mixing, and washing for the gene specimen, magnetic bead, and reagent solutions. The proposed automation system consists of a PC-based host application and an Arduino-based controller. The host application compiles a G code sequence file and interfaces with the controller to execute the compiled sequence. The controller executes stepper motor axis motion, time delay, and input-output manipulation. It drives the stepper motor with an open library, which provides a smooth linear acceleration profile. The controller also provides a homing sequence to establish the motor's reference position, and hard limit checking to prevent any over-travelling. The proposed system was implemented and its functionality was investigated, especially regarding positioning accuracy and velocity profile. PMID:26409535

    2015-11-01

    The increasing amount of data in industrial automation systems overburdens the user in process control and diagnosis tasks. One possibility to cope with these challenges consists of using smart assistance systems that automatically monitor and optimize processes. This article deals with aspects of data-driven assistance systems such as assistance functions, process models and data acquisition. The paper describes novel approaches for self-diagnosis and self-optimization, and shows how these assistance functions can be integrated in different industrial environments. The considered assistance functions are based on process models that are automatically learned from process data. Fault detection and isolation is based on the comparison of observations of the real system with predictions obtained by application of the process models. The process models are further employed for energy efficiency optimization of industrial processes. Experimental results are presented for fault detection and energy efficiency optimization of a drive system.

  9. Development of an automated fracture. Assessment system for nuclear structures

    International Nuclear Information System (INIS)

    A program system for fracture assessment of nuclear power plant structures has been developed. The system consists of an easy-to-use program for engineering analysis and an automated finite element (FE) program system for more accurate analysis with solid three-dimensional (3D) models. The VTTSIF (SIF stress intensity factor) program for engineering fracture assessment applies either the weight function method or superposition method in calculating the stress intensity factor, and the fatigue crack growth analysis is based on the Paris equation. The structural geometry cases of the VTTSIF program are organized in an extendable subroutine database. The generation of a 3D FE model of a cracked structure is automated by the ACR program (automatic finite element model generation for part through cracks). The FE analyses are created with generally accepted commercial programs, and the virtual crack extension method (VCE) is used for fracture parameter evaluation by the VTTVIRT postprocessor program (program for J-integral evaluation using virtual crack extension method). The several test cases have demonstrated that the accuracy of the present system is satisfactory for practical applications. (author)

  10. A fully automated high-throughput training system for rodents.

    Directory of Open Access Journals (Sweden)

    Rajesh Poddar

    Full Text Available Addressing the neural mechanisms underlying complex learned behaviors requires training animals in well-controlled tasks, an often time-consuming and labor-intensive process that can severely limit the feasibility of such studies. To overcome this constraint, we developed a fully computer-controlled general purpose system for high-throughput training of rodents. By standardizing and automating the implementation of predefined training protocols within the animal's home-cage our system dramatically reduces the efforts involved in animal training while also removing human errors and biases from the process. We deployed this system to train rats in a variety of sensorimotor tasks, achieving learning rates comparable to existing, but more laborious, methods. By incrementally and systematically increasing the difficulty of the task over weeks of training, rats were able to master motor tasks that, in complexity and structure, resemble ones used in primate studies of motor sequence learning. By enabling fully automated training of rodents in a home-cage setting this low-cost and modular system increases the utility of rodents for studying the neural underpinnings of a variety of complex behaviors.

  11. A system for automated, dismantlement of plutonium weapons components

    International Nuclear Information System (INIS)

    The development of advanced dismantlement technologies will play an integral part on the changing role of the DOE. As an important component to this effort, the ARIES (Automated Retirement and Integrated Extraction System) System is designed to provide a test bed for the development of technology for the dismantlement of the primaries of nuclear weapons (pits). The ARIES system will integrate and automate the processes of pit disassembly, plutonium, plutonium removal, preparation of oxide from plutonium metal, decontamination of non-plutonium parts, and in-line measurement of the products and wastes by state-of-the-art non-destructive assay (NDA) methods. No integrated method now exists for the dismantlement and recovery of nuclear material from many weapons designs. Even those assemblies for which recovery techniques have been established require extensive manual handling (with associated personnel exposure to radiation) and result in considerable waste generation during dismantlement. The disposition of excess plutonium will require a facility to disassemble and remove plutonium from the pits. ARIES will provide the methods to satisfy this goal while at the same time reducing waste generation, lowering personnel radiation exposures, and operating to the highest standards of safety and security. A description of the ARIES system is given

TMD is seeking to update it automation capabilities in capturing and processing DOE transportation information. TMD's Transportation Information Network (TIN) is an attempt to bring together transportation management, shipment tracking, research activities and software products in various stages of development. The TMD's Automated Transportation Management System (ATMS) proposes to assist the DOE and its contractors in performing their daily transportation management activities and to assist the DOE Environmental Management Division in its waste management responsibilities throughout the DOE complex. The ATMS system will center about the storage, handling and documentation involved in the environmental clean-up of DOE sites. Waste shipments will be moved to approved Treatment, Storage and Disposal (TSD) facilities and/or nuclear material repositories. An additional investment in shipping samples to analytical laboratories also involves packaging and documentation according to all applicable U.S. Department of Transportation (DOT) or International Air Transport Association (IATA) regulations. The most immediate goal of effectively managing DOE transportation management functions during the 1990's is an increase in automation capabilities of the DOE and its contractors. Subject-matter experts from various DOE site locations will be brought together to develop and refine these capabilities through the maximum use of computer applications. A major part of this effort will be the identification of the most economical modes of transportation and enhanced management reporting capabilities for transportation analysis. The ATMS system will also provide for increased strategic and shipment analysis during the 1990's and beyond in support of the DOE environmental mission

  15. Automated generation of nonlinear system characterization for sensor failure detection

    International Nuclear Information System (INIS)

    Independent estimation of critical signals is required for use in consistency checking of instrument outputs, and for isolating common-mode failures. When measurement redundancy is not available, this method can be used for monitoring sensor degradation or sensor drifts by on-line prediction of the sensor output. A methodology is developed to characterize a given critical signal as a function of other related variables in a process by a nonlinear minimum-term model. This steady-state characterization is fully automated and implemented on an IBM PC, and is applied for sensor failure monitoring in a power plant and a process control industrial system. 5 refs., 5 figs

  1. Automated synthesis of dependable mediators for heterogeneous interoperable systems

    International Nuclear Information System (INIS)

    Approaches to dependability and performance are challenged when systems are made up of networks of heterogeneous applications/devices, especially when operating in unpredictable open-world settings. The research community is tackling this problem and exploring means for enabling interoperability at the application level. The EU project CONNECT has developed a generic interoperability mechanism which relies on the on-the-fly synthesis of “CONNECTors”, that is software bridges that enable and adapt communication among heterogeneous devices. Dependability and Performance are relevant aspects of the system. In our previous work, we have identified generic dependability mechanisms for enhancing the dependability of CONNECTors. In this work, we introduce a set of generic strategies for automating the selection and application of an appropriate dependability mechanism. A case study based on a global monitoring system for environment and security (GMES) is used as a means for demonstrating the approach. - Highlights: • Method to automate the selection of a dependability mechanism to meet requirements. • Dependability mechanisms that allow interoperability among heterogeneous devices. • Method to find elements that must be enhanced to improve performance/dependability. • Demonstration through a case study based on the GMES EU Programme

    Scientific and technological progress of recent years in the production of the light emitting diodes (LEDs) has led to the expansion of areas of their application from the simplest systems to high precision lighting devices used in various fields of human activity. However, for all technology development at the present time it is very difficult to choose one or another brand of LEDs for realization of concrete devices designed for the implementation of high precision spatial and color measurements of various objects. In the world there are many measurement instruments for determining the various parameters of LEDs, but none of them are not capable to estimate comprehensively the LEDs spatial, spectral, and color parameters with the necessary accuracy and speed.

    Full Text Available The game of cricket and the use of technology in the sport have grown rapidly over the past decade. However, technology-based systems introduced to adjudicate decisions such as run outs, stumpings, boundary infringements and close catches are still prone to human error, and thus their acceptance has not been fully embraced by cricketing administrators. In particular, technology is not employed for bat-pad decisions. Although the snickometer may assist in adjudicating such decisions it depends heavily on human interpretation. The aim of this study is to investigate the use of Wavelets in developing an edgedetection adjudication system for the game of cricket. Artificial Intelligence (AI tools, namely Neural Networks, will be employed to automate this edge detection process. Live audio samples of ball-on-bat and ball-on-pad events from a cricket match will be recorded. DSP analysis, feature extraction and neural network classification will then be employed on these samples. Results will show the ability of the neural network to differentiate between these key events. This is crucial to developing a fully automated edge detection system.

  4. United States Department of Energy Automated Transportation Management System

    International Nuclear Information System (INIS)

    At the US Department of Energy (DOE) 80 transportation facilities, each contractor's transportation management operation has different internal and site specific procedures, and reports to a DOE regional Field Office Traffic Manager (FOTM). The DOE Transportation Management Program (TMP) has the responsibility to manage a transportation program for safe, efficient, and economical transportation of DOE-owned materials. The TMP develops and administers transportation/traffic operations management policies and programs for materials; including radioactive materials, other hazardous materials, hazardous substances, and hazardous wastes, pursuant to applicable federal regulations, such as the Code of Federal Register, Sections 40 and 49. Transportation management has become an increasingly critical primarily because of transportation issues regarding the shipment of radioactive materials and hazardous wastes that are frequently the focus of public concerns. A large shipments and requiring millions of business transactions necessitates the establishment of automated systems, programs, procedures, and controls to ensure that the transportation management process in being handled in a safe, efficient, and economical manner. As the mission of many DOE facilities changes from production of special nuclear materials for defense purposes to environmental restoration and waste management, the role of transportation management will become even more important to the safe and efficient movement of waste materials to prescribed locations. In support of this role, the Automated Transportation Management System (ATMS) was conceived to assist the DOE and its contractors in the performance of their day-to-day transportation management activities. The ATMS utilizes the latest in technology and will supply state-of-the-art automated transportation management for current and future DOE transportation requirements

  5. Diversity and testing requirements of programmable automation systems

    International Nuclear Information System (INIS)

    In the report programmable digital operation and safety automation systems for nuclear power plants are discussed. The programmable systems deviate by their properties and behaviour from the conventional non-programmable systems in such extent, that their verification and validation for safety critical applications requires new methods and practices. The safety assessment can not be based on conventional probabilistic methods due to the difficulties in the quantification of the reliability of the software and hardware. A safety critical programmable system shall include diverse redundant parts so that no residual program fault can not cause the failure of the intended function of the system. Although complete testing of a programmable system is impossible, different tests have a central role in the production and validation process of the system. Diversity is important also in confidence building measures for the implemented system. Independent analysis and testing of the system should use different methods and tools from those used in the production and validation process by the system vendor. Use of diversity and testing are concluded to be central issues in producing safe programmable system and in proving them to be safe enough. By combining functional and programming diversity in a suitable way one can produce a system that is safe enough without having a non-programmable back-up system. (48 refs., 10 figs., 2 tabs.)

  6. 3H-digoxin distribution in the nervous system in ventricular tachycardia

    International Nuclear Information System (INIS)

    The distribution of 3H-digoxin has been measured in a large number of tissues from the central, autonomic, and peripheral nervous system after the induction of ventricular tachycardia by infusing digoxin into anesthetized dogs. In most parts of the nervous system the tissue digoxin concentration was close to that in the cerebrospinal fluid. Digoxin accumulation in the choroid plexus probably represented a labeling of adenosine triphosphatase. There was a markedly higher concentration of digoxin in the neurohypophysis than in the adenohypophysis, and the very high levels in the neurohypophysis are hard to explain. There may be a relationship between the pituitary and the hypothalamic digoxin levels, although the concentration in the latter was unimpressive. The fornix showed a modest increase in 3H-digoxin concentration and may play a role, as its efferent discharge goes to the hypothalamus. The high concentration of digoxin in the area postrema suggests that this central nervous system structure is responsible, at least in part, for producing digoxin-induced cardiac arrhythmias. It may act as a sensing organ sensitive to blood digoxin concentration. Either it is the only central nervous structure implicated, or it is involved together with the fornix-hypothalamus-hypophysis pathways. Further proof is given for the importance of the autonomic nervous system in cardiac arrhythmias by the high digoxin levels in the superior cervical sympathetic ganglion and adrenal medulla

  8. Angiographic study of systemic-pulmonary collateral in pulmonary atresia with ventricular septal defect

    International Nuclear Information System (INIS)

    Objective: To evaluate the angiography in demonstrating the development of systemic-pulmonary collateral vessels and pulmonary arteries, and its clinical significance in pulmonary atresia with ventricular septal defect (PA + VSD). Methods: The findings of angiography of the right ventricle and aorta arch and upper portion of the descending thoracic aorta in 98 cases with PA + VSD were retrospectively studied including 63 additional selective angiography of collateral vessels. The types of systemic-pulmonary collateral vessels and the development of left and right native pulmonary arteries with or without fusion were emphatically analyzed, etc. Results: Among those 98 cases, the pulmonary arteries were supplied by patent ductus arteriosus in 14(14%), 11 of them were infants and young children; and by direct aortopulmonary collaterals in 43(44%); by multiple origin of systemic-pulmonary artery collaterals in 41(42%). 60 of 98 cases were visualized the presence of left and right native pulmonary arteries through collateral vessels. Among them, the hypoplasia of left and/or right pulmonary arteries was found. Conclusion: Angiography of right ventricle and aorta combined with necessary selective angiography of collateral vessels was still an indispensable method in the demonstration of systemic-pulmonary collateral vessels and development of pulmonary arteries, and provided the main basis for the selection of indications for interventional/surgical therapy

  10. Optimizing human-system interface automation design based on a skill-rule-knowledge framework

    International Nuclear Information System (INIS)

    This study considers the technological change that has occurred in complex systems within the past 30 years. The role of human operators in controlling and interacting with complex systems following the technological change was also investigated. Modernization of instrumentation and control systems and components leads to a new issue of human-automation interaction, in which human operational performance must be considered in automated systems. The human-automation interaction can differ in its types and levels. A system design issue is usually realized: given these technical capabilities, which system functions should be automated and to what extent? A good automation design can be achieved by making an appropriate human-automation function allocation. To our knowledge, only a few studies have been published on how to achieve appropriate automation design with a systematic procedure. Further, there is a surprising lack of information on examining and validating the influences of levels of automation (LOAs) on instrumentation and control systems in the advanced control room (ACR). The study we present in this paper proposed a systematic framework to help in making an appropriate decision towards types of automation (TOA) and LOAs based on a 'Skill-Rule-Knowledge' (SRK) model. From the evaluating results, it was shown that the use of either automatic mode or semiautomatic mode is insufficient to prevent human errors. For preventing the occurrences of human errors and ensuring the safety in ACR, the proposed framework can be valuable for making decisions in human-automation allocation.

    2011-05-01

    Full Text Available Performance tuning of Database Management Systems (DBMS is complex as well as challenging task since it involves identification and alteration of several key performance tuning parameters. The quality of tuning and the extent of performance enhancement achieved greatlydepend on the skill and experience of the Database Administrator (DBA. The ability of our automated database design to adapt to dynamically changing inputs makes them ideal candidates for employing them for tuning purpose. In this paper, a novel tuning algorithm based on new script estimated tuning parameters is presented. The key performance indicators are proactively monitored and fed as input to the proposed script and the trained networksestimates the suitable size of the buffer cache, shared pooland redo log buffer size. The tuner alters these tuning parameters using the estimated values using a rate change computing algorithm. The preliminary results show that the proposed method is effective in improving the query response time for a variety of workload types. To summarize, this paper presents a self tuned database systemor we can say, automated database system whose main focus is performance optimization.

  12. Automated spike preparation system for Isotope Dilution Mass Spectrometry (IDMS)

    International Nuclear Information System (INIS)

    Isotope Dilution Mass Spectrometry (IDMS) is a method frequently employed to measure dissolved, irradiated nuclear materials. A known quantity of a unique isotope of the element to be measured (referred to as the ''spike'') is added to the solution containing the analyte. The resulting solution is chemically purified then analyzed by mass spectrometry. By measuring the magnitude of the response for each isotope and the response for the ''unique spike'' then relating this to the known quantity of the ''spike'', the quantity of the nuclear material can be determined. An automated spike preparation system was developed at the Savannah River Site (SRS) to dispense spikes for use in IDMS analytical methods. Prior to this development, technicians weighed each individual spike manually to achieve the accuracy required. This procedure was time-consuming and subjected the master stock solution to evaporation. The new system employs a high precision SMI Model 300 Unipump dispenser interfaced with an electronic balance and a portable Epson HX-20 notebook computer to automate spike preparation

  13. Automated data acquisition and analysis system for inventory verification

    International Nuclear Information System (INIS)

    A real-time system is proposed which would allow CLO Safeguards Branch to conduct a meaningful inventory verification using a variety of NDA instruments. The overall system would include the NDA instruments, automated data handling equipment, and a vehicle to house and transport the instruments and equipment. For the purpose of the preliminary cost estimate a specific data handling system and vehicle were required. A Tracor Northern TN-11 data handling system including a PDP-11 minicomputer and a measurement vehicle similar to the Commission's Regulatory Region I van were used. The basic system is currently estimated to cost about $100,000, and future add-ons which would expand the systems' capabilities are estimated to cost about $40,000. The concept of using a vehicle in order to permanently rack mount the data handling equipmentoffers a number of benefits such as control of equipment environment and allowance for improvements, expansion, and flexibility in the system. Justification is also presented for local design and assembly of the overall system. A summary of the demonstration system which illustrates the advantages and feasibility of the overall system is included in this discussion. Two ideas are discussed which are not considered to be viable alternatives to the proposed system: addition of the data handling capabilities to the semiportable ''cart'' and use of a telephone link to a large computer center

    Recent years have witnessed great development of TLA (Total Laboratory Automation) technology, however, its application hit the bottleneck of high cost and openess to other parties' instruments. Specifically speaking, the initial purchase of the medical devices requires large sum of money and the new system can hardly be compatible with existing equipment. This thesis proposes a new thought for system implementation that through incremental upgrade, the initial capital investment can be reduced and through open architecture and interfaces, the seamless connection of different devices can be achieved. This thesis elaborates on the standards that open architecture design should follow in aspect of mechanics, electro-communication and information interaction and the key technology points in system implementation.

    1991-01-01

    An implantable electromechanical ventricular assist system (VAS) intended for permanent human use was developed. It consisted of a conically shaped pumping chamber, a polyolefin (Hexsyn) rubber diaphragm attached to a pusher-plate, and a compact actuator with a direct current brushless motor and a planetary rollerscrew. The outer diameter was 97 mm, and the total thickness was 70 mm. This design was chosen to give a stroke volume of 63 ml. The device weighs 620 g, with a total volume of 360 ml. The pump can provide 8 L/min flow against 120 mmHg afterload with a preload of 10 mmHg. The inner surface of the device, including the pumping chamber and diaphragm, was made biocompatible with a dry gelatin coating. To date, two subacute (2 and 6 day) calf studies have been conducted. The pump showed reasonable anatomic fit inside the left thorax, and the entire system functioned satisfactorily in both the fill-empty mode using the Hall effect sensor signals and the conventional fixed rate mode. There were no thromboembolic complications despite no anticoagulation therapy. The system now is being endurance tested greater than 10 weeks (9 million cycles). This VAS is compact, low noise, easy to control, and has excellent biocompatibility. PMID:1751133

  18. A Mobile Automated Tomographic Gamma Scanning System - 13231

    International Nuclear Information System (INIS)

    Canberra Industries have recently designed and built a new automated Tomographic Gamma Scanning (TGS) system for mobile deployment. The TGS technique combines high-resolution gamma spectroscopy with low spatial resolution 3-dimensional image reconstruction to provide increased accuracy over traditional approaches for the assay of non-uniform source distributions in low-to medium-density, non-heterogeneous matrices. Originally pioneered by R. Estep at Los Alamos National Laboratory (LANL), the TGS method has been further developed and commercialized by Canberra Industries in recent years. The present system advances the state of the art on several fronts: it is designed to be housed in a standard cargo transport container for ease of transport, allowing waste characterization at multiple facilities under the purview of a single operator. Conveyor feed, drum rotator, and detector and collimator positioning mechanisms operated by programmable logic control (PLC) allow automated batch mode operation. The variable geometry settings can accommodate a wide range of waste packaging, including but not limited to standard 220 liter drums, 380 liter overpack drums, and smaller 20 liter cans. A 20 mCi Eu-152 transmission source provides attenuation corrections for drum matrices up to 1 g/cm3 in TGS mode; the system can be operated in Segmented Gamma Scanning (SGS) mode to measure higher density drums. To support TGS assays at higher densities, the source shield is sufficient to house an alternate Co-60 transmission source of higher activity, up to 250 mCi. An automated shutter and attenuator assembly is provided for operating the system with a dual intensity transmission source. The system's 1500 kg capacity rotator turntable can handle heavy containers such as concrete lined 380 liter overpack drums. Finally, data acquisition utilizes Canberra's Broad Energy Germanium (BEGE) detector and Lynx MCA, with 32 k channels, providing better than 0.1 keV/channel resolution to support

    Ventricular enlargement in normal aging frequently forces the radiological diagnosis of hydrocephalus, but the reliability of Evans' index as a radiological marker of abnormal ventricular enlargement (values > 0.30) during aging is not assessed. Here we analyze ventricular size during aging and the reliability of Evans' index as a radiological marker of abnormal ventricular enlargement. We calculated Evans' index in the axial Computed Tomography scans of 1221 consecutive individuals (aged 45-101 years) from an emergency department. Stratified analysis of one-year cohorts showed that the mean Evans' index value per class was invariably 0.30 and Evans' index values increased with age. The risk of having an Evans' index value > 0.30 increased by 7.8% per year of age (p 0.30 should reflect an underlying neurological condition in every individual. PMID:26919252

    2013-01-01

    A semi-supervised model of peer review is introduced that is intended to overcome the bias and incompleteness of traditional peer review. Traditional approaches are reliant on human biases, while consensus decision-making is constrained by sparse information. Here, the architecture for one potential improvement (a semi-supervised, human-assisted classifier) to the traditional approach will be introduced and evaluated. To evaluate the potential advantages of such a system, hypothetical receiver operating characteristic (ROC) curves for both approaches will be assessed. This will provide more specific indications of how automation would be beneficial in the manuscript evaluation process. In conclusion, the implications for such a system on measurements of scientific impact and improving the quality of open submission repositories will be discussed.

    2015-06-01

    Full Text Available The distribution automation system (DAS is vulnerable to cyber-attacks due to the widespread use of terminal devices and standard communication protocols. On account of the cost of defense, it is impossible to ensure the security of every device in the DAS. Given this background, a novel quantitative vulnerability assessment model of cyber security for DAS is developed in this paper. In the assessment model, the potential physical consequences of cyber-attacks are analyzed from two levels: terminal device level and control center server level. Then, the attack process is modeled based on game theory and the relationships among different vulnerabilities are analyzed by introducing a vulnerability adjacency matrix. Finally, the application process of the proposed methodology is illustrated through a case study based on bus 2 of the Roy Billinton Test System (RBTS. The results demonstrate the reasonability and effectiveness of the proposed methodology.

    To enable protocol standardization, sharing, and efficient implementation across laboratory automation platforms, we have further developed the PR-PR open-source high-level biology-friendly robot programming language as a cross-platform laboratory automation system. Beyond liquid-handling robotics, PR-PR now supports microfluidic and microscopy platforms, as well as protocol translation into human languages, such as English. While the same set of basic PR-PR commands and features are available for each supported platform, the underlying optimization and translation modules vary from platform to platform. Here, we describe these further developments to PR-PR, and demonstrate the experimental implementation and validation of PR-PR protocols for combinatorial modified Golden Gate DNA assembly across liquid-handling robotic, microfluidic, and manual platforms. To further test PR-PR cross-platform performance, we then implement and assess PR-PR protocols for Kunkel DNA mutagenesis and hierarchical Gibson DNA assembly for microfluidic and manual platforms.

Methods N = 100 patients with known or suspected coronary artery disease were examined at rest with 99 mTc-tetrofosmin gated MPS and cardiac MR imaging. Left ventricular end-diastolic volume (EDV, end-systolic volume (ESV, stroke volume (SV and ejection fraction (EF were obtained by analysing gated MPS data with four different programs: Quantitative Gated SPECT (QGS, GE MyoMetrix, Emory Cardiac Toolbox (ECTb and Exini heart. Results All programs showed a mean bias compared to MR imaging of approximately -30% for EDV (-22 to -34%, p Conclusions Gated MPS, systematically underestimates left ventricular volumes by approximately 30% and shows a high variability, especially for ESV. For EF, accuracy was better, with a mean bias between -15 and 6% of EF. It may be of value to take this into consideration when determining absolute values of LV volumes and EF in a clinical setting.

Methods In this prospective study TomTec LV Analysis TEE© Software was used for semi-automatic endocardial border detection, reconstruction, and volume-rendering of the clinical 3D echocardiographic data. A newly developed software program MVCP FemCoGen©, written in Delphi, reformats the TomTec file structures in five patients for use in ABAQUS and allows visualization of regional deformation of the LV. Results This study demonstrates that a fully automated importation of 3D TEE data into FEM modeling is feasible and can be efficiently accomplished in the operating room. Conclusion For complete intraoperative 3D LV finite element analysis, three input elements are necessary: 1. time-gaited, reality-based structural information, 2. continuous LV pressure and 3. instantaneous tissue elastance. The first of these elements is now available using the methods presented herein.

    A script system was developed to automate and streamline portions of the CFD process. The system was designed to facilitate the use of CFD flow solvers on supercomputer and workstation platforms within a parametric design event. Integrating solver pre- and postprocessing phases, the fully automated ADTT script system marshalled the required input data, submitted the jobs to available computational resources, and processed the resulting output data. A number of codes were incorporated into the script system, which itself was part of a larger integrated design environment software package. The IDE and scripts were used in a design event involving a wind tunnel test. This experience highlighted the need for efficient data and resource management in all parts of the CFD process. To facilitate the use of CFD methods to perform parametric design studies, the script system was developed using UNIX shell and Perl languages. The goal of the work was to minimize the user interaction required to generate the data necessary to fill a parametric design space. The scripts wrote out the required input files for the user-specified flow solver, transferred all necessary input files to the computational resource, submitted and tracked the jobs using the resource queuing structure, and retrieved and post-processed the resulting dataset. For computational resources that did not run queueing software, the script system established its own simple first-in-first-out queueing structure to manage the workload. A variety of flow solvers were incorporated in the script system, including INS2D, PMARC, TIGER and GASP. Adapting the script system to a new flow solver was made easier through the use of object-oriented programming methods. The script system was incorporated into an ADTT integrated design environment and evaluated as part of a wind tunnel experiment. The system successfully generated the data required to fill the desired parametric design space. This stressed the computational

    2012-06-01

    Full Text Available Studies on the collagen system of the human myocardium are still limited compared to those on small laboratory animals. The aim of this work was to observe the collagen tissue of the myocardium of the human heart as a function of age. The types of collagen, as well as the density of collagen tissue and the diameter of collagen fibrils, were examined. Fragments of the left ventricular wall from 15 hearts, 5 from children, 5 from young adults, and 5 from elderly individuals, were analyzed by using the Picrosirius-polarization method and by transmission electron microscopy (TEM. The results showed the presence of collagen type III and collagen type I, both in the endomysium and perimysium of the 3 groups studied. Measurements of collagen content in myocardial tissue displayed that both endomysial and perimysial collagen increase in number and thickness in the adult and elderly. These histochemical results coincided with the observations obtained with the electron microscope in showing an increase in the number of collagen fibrils with a large diameter in the adult and elderly hearts. The present results on cardiac collagen may be important for assessing the pathogenesis of several cardiopathies in the hearts of children, young adults, and the elderly.

  18. A compartmentalized mathematical model of the β1-adrenergic signaling system in mouse ventricular myocytes.

    Directory of Open Access Journals (Sweden)

    Vladimir E Bondarenko

    Full Text Available The β1-adrenergic signaling system plays an important role in the functioning of cardiac cells. Experimental data shows that the activation of this system produces inotropy, lusitropy, and chronotropy in the heart, such as increased magnitude and relaxation rates of [Ca(2+]i transients and contraction force, and increased heart rhythm. However, excessive stimulation of β1-adrenergic receptors leads to heart dysfunction and heart failure. In this paper, a comprehensive, experimentally based mathematical model of the β1-adrenergic signaling system for mouse ventricular myocytes is developed, which includes major subcellular functional compartments (caveolae, extracaveolae, and cytosol. The model describes biochemical reactions that occur during stimulation of β1-adrenoceptors, changes in ionic currents, and modifications of Ca(2+ handling system. Simulations describe the dynamics of major signaling molecules, such as cyclic AMP and protein kinase A, in different subcellular compartments; the effects of inhibition of phosphodiesterases on cAMP production; kinetics and magnitudes of phosphorylation of ion channels, transporters, and Ca(2+ handling proteins; modifications of action potential shape and duration; magnitudes and relaxation rates of [Ca(2+]i transients; changes in intracellular and transmembrane Ca(2+ fluxes; and [Na(+]i fluxes and dynamics. The model elucidates complex interactions of ionic currents upon activation of β1-adrenoceptors at different stimulation frequencies, which ultimately lead to a relatively modest increase in action potential duration and significant increase in [Ca(2+]i transients. In particular, the model includes two subpopulations of the L-type Ca(2+ channels, in caveolae and extracaveolae compartments, and their effects on the action potential and [Ca(2+]i transients are investigated. The presented model can be used by researchers for the interpretation of experimental data and for the developments of

    2005-05-01

    The Cognitive Drug Research (CDR) computerized assessment system has been in use in worldwide clinical trials for over 20 years. It is a computer based system which assesses core aspects of human cognitive function including attention, information, working memory and long-term memory. It has been extensively validated and can be performed by a wide range of clinical populations including patients with various types of dementia. It is currently in worldwide use in clinical trials to evaluate new medicines, as well as a variety of programs involving the effects of age, stressors illnesses and trauma upon human cognitive function. Besides being highly sensitive to drugs which will impair or improve function, its utility has been maintained over the last two decades by constantly increasing the number of platforms upon which it can operate. Besides notebook versions, the system can be used on a wrist worn device, PDA, via tht telephone and over the internet. It is the most widely used automated cognitive function assessment system in worldwide clinical research. It has dozens of parallel forms and requires little training to use or administer. The basic development of the system wil be identified, and the huge databases (normative, patient population, drug effects) which have been built up from hundreds of clinical trials will be described. The system is available for use in virtually any environment or type of trial.

    Cables are critical load carrying members of cable-stayed bridges; monitoring tension forces of the cables provides valuable information for SHM of the cable-stayed bridges. Monitoring systems for the cable tension can be efficiently realized using wireless smart sensors in conjunction with vibration-based cable tension estimation approaches. This study develops an automated cable tension monitoring system using MEMSIC's Imote2 smart sensors. An embedded data processing strategy is implemented on the Imote2-based wireless sensor network to calculate cable tensions using a vibration-based method, significantly reducing the wireless data transmission and associated power consumption. The autonomous operation of the monitoring system is achieved by AutoMonitor, a high-level coordinator application provided by the Illinois SHM Project Services Toolsuite. The monitoring system also features power harvesting enabled by solar panels attached to each sensor node and AutoMonitor for charging control. The proposed wireless system has been deployed on the Jindo Bridge, a cable-stayed bridge located in South Korea. Tension forces are autonomously monitored for 12 cables in the east, land side of the bridge, proving the validity and potential of the presented tension monitoring system for real-world applications.

  5. A fully automated system for adherent cells microinjection.

    Science.gov (United States)

    Becattini, Gabriele; Mattos, Leonardo S; Caldwell, Darwin G

    2014-01-01

    This paper proposes an automated robotic system to perform cell microinjections to relieve human operators from this highly difficult and tedious manual procedure. The system, which uses commercial equipment currently found on most biomanipulation laboratories, consists of a multitask software framework combining computer vision and robotic control elements. The vision part features an injection pipette tracker and an automatic cell targeting system that is responsible for defining injection points within the contours of adherent cells in culture. The main challenge is the use of bright-field microscopy only, without the need for chemical markers normally employed to highlight the cells. Here, cells are identified and segmented using a threshold-based image processing technique working on defocused images. Fast and precise microinjection pipette positioning over the automatically defined targets is performed by a two-stage robotic system which achieves an average injection rate of 7.6 cells/min with a pipette positioning precision of 0.23 μm. The consistency of these microinjections and the performance of the visual targeting framework were experimentally evaluated using two cell lines (CHO-K1 and HEK) and over 500 cells. In these trials, the cells were automatically targeted and injected with a fluorescent marker, resulting in a correct cell detection rate of 87% and a successful marker delivery rate of 67.5%. These results demonstrate that the new system is capable of better performances than expert operators, highlighting its benefits and potential for large-scale application. PMID:24403406

  9. A Mobile Automated Characterization System (MACS) for indoor floor characterization

    International Nuclear Information System (INIS)

    The Savannah River Technology Center (SRTC) and Oak Ridge National Laboratory are developing an advanced Mobile Automated Characterization System (MACS) to characterize indoor contaminated floors. MACS is based upon Semi-Intelligent Mobile Observing Navigator (SIMON), an earlier floor characterization system developed at SRTC. MACS will feature enhanced navigation systems, operator interface, and an interface to simplify integration of additional sensors. The enhanced navigation system will provide the capability to survey large open areas much more accurately than is now possible with SIMON, which is better suited for hallways and corridors that provide the means for recalibrating position and heading. MACS operator interface is designed to facilitate MACS's use as a tool for health physicists, thus eliminating the need for additional training in the robot's control language. Initial implementation of MACS will use radiation detectors. Additional sensors, such as PCB sensors currently being developed, will be integrated on MACS in the future. Initial use of MACS will be focused toward obtaining comparative results with manual methods. Surveys will be conducted both manually and with MACS to compare relative costs and data quality. While clear cost benefits anticipated, data quality benefits should be even more significant

    The Automated Retirement and Integrated Extraction System (ARMS) is a new development and demonstration glove-box line planned for installation at TA-55. The mission of ARIES is development of advanced technologies for disassembly of retired plutonium weapons components. ARIES is subdivided into the following subsystems: Receiving (airlock to system controlled atmosphere), Disassembly (parts are separated into hemishells), Plutonium Consolidation, Americium Removal, Decontamination (removal of trace plutonium from nonplutonium parts), and Nondestructive Assay (NDA). The ARIES NDA subsystem consists of four computer-based NDA instruments (calorimeter, gamma-ray isotopic system, segmented gamma scanner, and an active/passive neutron multiplicity counter); a robot to load and unload the instruments; and a host computer to sense and control the instrument status, schedule measurements, archive the results of the assays, and direct the activities of the robot. The NDA subsystem will be fully integrated into the ARIES process line and will provide assays of nuclear material that are inherently safer and more efficient than nonautomated systems.

    Full Text Available Citrus is number one group of fruits grown in more than 140 countries in the world. Micro-irrigation systems and fertigation management is one of the main concerns of the modem citrus fruit production irrespective of availability of soil, water and fertilizer resources. A variety of recommendations have emerged world over on irrigation systems and fertigation based on soil and leaf analysis of the nutrients, evapo-transpiration and water use pattern. The research review of literature has revealed best promising results on irrigation scheduling based on depletion pattern of soil available water content, irrigation systems and fertigation. Various micro-irrigation systems have established their superiority over traditionally used flood irrigation with micro-jets having little edge over rest of the others. Similarly, fertigation has shown good responses on growth, yield, quality and uniform distribution pattern of applied nutrients within the plant rootzone compared to band placement involving comparatively localized fertilization. Automated fertigation in citrus orchards is a new concept, which would be the only solitary choice amongst many irrigation monitoring methods in near future. The present status of the review on micro-irrigation and fertigation in citrus cultivars is clearly indicated in this article.

  12. AI and workflow automation: The prototype electronic purchase request system

    Compton, Michael M.; Wolfe, Shawn R.

    1994-01-01

    Automating 'paper' workflow processes with electronic forms and email can dramatically improve the efficiency of those processes. However, applications that involve complex forms that are used for a variety of purposes or that require numerous and varied approvals often require additional software tools to ensure that (1) the electronic form is correctly and completely filled out, and (2) the form is routed to the proper individuals and organizations for approval. The prototype electronic purchase request (PEPR) system, which has been in pilot use at NASA Ames Research Center since December 1993, seamlessly links a commercial electronics forms package and a CLIPS-based knowledge system that first ensures that electronic forms are correct and complete, and then generates an 'electronic routing slip' that is used to route the form to the people who must sign it. The PEPR validation module is context-sensitive, and can apply different validation rules at each step in the approval process. The PEPR system is form-independent, and has been applied to several different types of forms. The system employs a version of CLIPS that has been extended to support AppleScript, a recently-released scripting language for the Macintosh. This 'scriptability' provides both a transparent, flexible interface between the two programs and a means by which a single copy of the knowledge base can be utilized by numerous remote users.

  19. Anomaly detection in an automated safeguards system using neural networks

    International Nuclear Information System (INIS)

    An automated safeguards system must be able to detect an anomalous event, identify the nature of the event, and recommend a corrective action. Neural networks represent a new way of thinking about basic computational mechanisms for intelligent information processing. In this paper, we discuss the issues involved in applying a neural network model to the first step of this process: anomaly detection in materials accounting systems. We extend our previous model to a 3-tank problem and compare different neural network architectures and algorithms. We evaluate the computational difficulties in training neural networks and explore how certain design principles affect the problems. The issues involved in building a neural network architecture include how the information flows, how the network is trained, how the neurons in a network are connected, how the neurons process information, and how the connections between neurons are modified. Our approach is based on the demonstrated ability of neural networks to model complex, nonlinear, real-time processes. By modeling the normal behavior of the processes, we can predict how a system should be behaving and, therefore, detect when an abnormality occurs

  20. Automated recognition system for ELM classification in JET

    International Nuclear Information System (INIS)

    Edge localized modes (ELMs) are instabilities occurring in the edge of H-mode plasmas. Considerable efforts are being devoted to understanding the physics behind this non-linear phenomenon. A first characterization of ELMs is usually their identification as type I or type III. An automated pattern recognition system has been developed in JET for off-line ELM recognition and classification. The empirical method presented in this paper analyzes each individual ELM instead of starting from a temporal segment containing many ELM bursts. The ELM recognition and isolation is carried out using three signals: Dα, line integrated electron density and stored diamagnetic energy. A reduced set of characteristics (such as diamagnetic energy drop, ELM period or Dα shape) has been extracted to build supervised and unsupervised learning systems for classification purposes. The former are based on support vector machines (SVM). The latter have been developed with hierarchical and K-means clustering methods. The success rate of the classification systems is about 98% for a database of almost 300 ELMs.

    The goal of the 2.5 year Distributed Intelligent Automated Demand Response (DIADR) project was to reduce peak electricity load of Sutardja Dai Hall at UC Berkeley by 30% while maintaining a healthy, comfortable, and productive environment for the occupants. We sought to bring together both central and distributed control to provide “deep” demand response1 at the appliance level of the building as well as typical lighting and HVAC applications. This project brought together Siemens Corporate Research and Siemens Building Technology (the building has a Siemens Apogee Building Automation System (BAS)), Lawrence Berkeley National Laboratory (leveraging their Open Automated Demand Response (openADR), Auto-­Demand Response, and building modeling expertise), and UC Berkeley (related demand response research including distributed wireless control, and grid-­to-­building gateway development). Sutardja Dai Hall houses the Center for Information Technology Research in the Interest of Society (CITRIS), which fosters collaboration among industry and faculty and students of four UC campuses (Berkeley, Davis, Merced, and Santa Cruz). The 141,000 square foot building, occupied in 2009, includes typical office spaces and a nanofabrication laboratory. Heating is provided by a district heating system (steam from campus as a byproduct of the campus cogeneration plant); cooling is provided by one of two chillers: a more typical electric centrifugal compressor chiller designed for the cool months (Nov-­ March) and a steam absorption chiller for use in the warm months (April-­October). Lighting in the open office areas is provided by direct-­indirect luminaries with Building Management System-­based scheduling for open areas, and occupancy sensors for private office areas. For the purposes of this project, we focused on the office portion of the building. Annual energy consumption is approximately 8053 MWh; the office portion is estimated as 1924 MWh.

    This paper introduces as FRP resin product processing system using robots. Automatic processing by means of robots requires considerations on positioning of delivered workpieces, correction of positional shift of workpieces, monitoring of tools and cutters, disposal of chips, and dust and noise preventive measures. In a bath tank drilling and deburring system, robots should measure and correct the positional shift of workpieces, exchange tools automatically, and shut down the system upon occurrence of anomaly in processing. The wall panel processing system performs transportation of products by using a lift and carry system in consideration of preventing nicks on the transportation side a product. Workpiece positioning is performed by lifting and pressing them onto the standard plate on the upper portion of panel, and the thickness and length are measured and corrected by a workpiece shift correcting sensor disposed on a robot. The purification tank partition drilling system has shuttle-type transportation devices installed on both flanks of a robot. This is a high-efficiency system requiring no robot downtime. A dust collecting duct is disposed below the positioning device to prevent chips from leaking outside the device. 4 figs., 7 tabs.

    1995-11-01

    The Bicron Surveyor MX is a portable radiation monitoring instrument used by the Office of Radiation Protection at Oak Ridge National Laboratory. This instrument must be calibrated in order to assure reliable operation. A manual calibration procedure was developed, but it was time consuming and repetitive. Therefore, an automated tester station that would allow the technicians to calibrate the instruments faster and more reliably was developed. With the automated tester station, calibration records and accountability could be generated and maintained automatically. This allows the technicians to concentrate on repairing defective units. The Automated Bicron Tester consists of an operator interface, an analog board, and a digital controller board. The panel is the user interface that allows the technician to communicate with the tester. The analog board has an analog-to-digital converter (ADC) that converts the signals from the instrument into digital data that the tester can manipulate. The digital controller board contains the circuitry to perform the test and to communicate the results to the host personal computer (PC). The tester station is connected to the unit under test through a special test harness that attaches to a header on the Bicron. The tester sends pulse trains to the Bicron and measures the resulting meter output. This is done to determine if the unit is functioning properly. The testers are connected to the host PC through an RS-485 serial line. The host PC polls all the tester stations that are connected to it and collects data from those that have completed a calibration. It logs these data and stores the record in a format ready for export to the Maintenance, Accountability, Jobs, and Inventory Control (MAJIC) database. It also prints a report. The programs for the Automated Bicron Tester and the host are written in the C language.

    The on-going transformation from the current US Air Traffic System (ATS) to the Next Generation Air Traffic System (NextGen) will force the introduction of new automated systems and most likely will cause automation to migrate from ground to air. This will yield new function allocations between humans and automation and therefore change the roles and responsibilities in the ATS. Yet, safety in NextGen is required to be at least as good as in the current system. We therefore need techniques to evaluate the safety of the interactions between humans and automation. We think that current human factor studies and simulation-based techniques will fall short in front of the ATS complexity, and that we need to add more automated techniques to simulations, such as model checking, which offers exhaustive coverage of the non-deterministic behaviors in nominal and off-nominal scenarios. In this work, we present a verification approach based both on simulations and on model checking for evaluating the roles and responsibilities of humans and automation. Models are created using Brahms (a multi-agent framework) and we show that the traditional Brahms simulations can be integrated with automated exploration techniques based on model checking, thus offering a complete exploration of the behavioral space of the scenario. Our formal analysis supports the notion of beliefs and probabilities to reason about human behavior. We demonstrate the technique with the Ueberligen accident since it exemplifies authority problems when receiving conflicting advices from human and automated systems.

    Full Text Available Automatic identification of garment design class might play an important role in the garments and fashion industry. To achieve this, essential initial works are found in the literature. For example, construction of a garment database, automatic segmentation of garments from real life images, categorizing them into the type of garments such as shirts, jackets, tops, skirts, etc. It is now essential to find a system such that it will be possible to identify the particular design (printed, striped or single color of garment product for an automated system to recommend the garment trends. In this paper, we have focused on this specific issue and thus propose two new descriptors namely Completed CENTRIST (cCENTRIST and Ternary CENTRIST (tCENTRIST. To test these descriptors, we used two different publically available databases. The experimental results of these databases demonstrate that both cCENTRIST and tCENTRIST achieve nearly about 3% more accuracy than the existing state-of-the art methods.

  12. Automation: the competitive edge for HMOs and other alternative delivery systems.

    1987-12-01

    Until recently, many, if not most, Health Maintenance Organizations (HMO) were not automated. Moreover, HMOs that were automated tended to be automated only on a limited basis. Recently, however, the highly competitive marketplace within which HMOs and other Alternative Delivery Systems (ADS) exist has required that they operate at a maximum effectiveness and efficiency. Given the complex nature of ADSs, the volume of transactions in ADSs, the large number of members served by ADSs, and the numerous providers who are paid at different rates and on different bases by ADSs, it is impossible for an ADS to operate effectively or efficiently, let alone show optimal performance, without a sophisticated, comprehensive automated system. Reliable automated systems designed specifically to address ADS functions such as enrollment and premium billing, finance and accounting, medical information and patient management, and marketing have recently become available at a reasonable cost.

  13. Automated neural network-based instrument validation system

    2000-10-01

    In a complex control process, instrument calibration is periodically performed to maintain the instruments within the calibration range, which assures proper control and minimizes down time. Instruments are usually calibrated under out-of-service conditions using manual calibration methods, which may cause incorrect calibration or equipment damage. Continuous in-service calibration monitoring of sensors and instruments will reduce unnecessary instrument calibrations, give operators more confidence in instrument measurements, increase plant efficiency or product quality, and minimize the possibility of equipment damage during unnecessary manual calibrations. In this dissertation, an artificial neural network (ANN)-based instrument calibration verification system is designed to achieve the on-line monitoring and verification goal for scheduling maintenance. Since an ANN is a data-driven model, it can learn the relationships among signals without prior knowledge of the physical model or process, which is usually difficult to establish for the complex non-linear systems. Furthermore, the ANNs provide a noise-reduced estimate of the signal measurement. More importantly, since a neural network learns the relationships among signals, it can give an unfaulted estimate of a faulty signal based on information provided by other unfaulted signals; that is, provide a correct estimate of a faulty signal. This ANN-based instrument verification system is capable of detecting small degradations or drifts occurring in instrumentation, and preclude false control actions or system damage caused by instrument degradation. In this dissertation, an automated scheme of neural network construction is developed. Previously, the neural network structure design required extensive knowledge of neural networks. An automated design methodology was developed so that a network structure can be created without expert interaction. This validation system was designed to monitor process sensors plant

    2010-07-08

    Daylight responsive dimming systems have been used in few buildings to date because they require improvements to improve reliability. The key underlying factor contributing to poor performance is the variability of the ratio of the photosensor signal to daylight workplane illuminance in accordance with sun position, sky condition, and fenestration condition. Therefore, this paper describes the integrated systems between automated roller shade systems and daylight responsive dimming systems with an improved closed-loop proportional control algorithm, and the relative performance of the integrated systems and single systems. The concept of the improved closed-loop proportional control algorithm for the integrated systems is to predict the varying correlation of photosensor signal to daylight workplane illuminance according to roller shade height and sky conditions for improvement of the system accuracy. In this study, the performance of the integrated systems with two improved closed-loop proportional control algorithms was compared with that of the current (modified) closed-loop proportional control algorithm. In the results, the average maintenance percentage and the average discrepancies of the target illuminance, as well as the average time under 90percent of target illuminance for the integrated systems significantly improved in comparison with the current closed-loop proportional control algorithm for daylight responsive dimming systems as a single system.

  17. Comparison of left ventricular functional parameters obtained from three different commercial automated software cardiac quantification program packages and their intraobserver reproducibility

    International Nuclear Information System (INIS)

    Electrocardiogram (ECG)-gated myocardial perfusion scintigraphy (MPS) can be used to determine several cardiac functional parameters (e.g., left ventricular ejection fraction (LVEF), end-diastolic volume (EDV), and end-systolic volume (ESV)). In this study, we aimed to compare these cardiac functional parameters calculated by the following cardiac quantification programs: Emory Cardiac Toolbox (ECTb), Quantitative Gated SPECT (QGS), and Myometrix. We also evaluated reproducibility of the cardiac programs. Fifty-seven patients (27 male, 30 female) at Elazig Research and Training Hospital from 2008 to 2009 were included in this study. In all patients, 99mTc-methoxyisobutylisonitril (MIBI) ECG-Gated (8-bin frame mode) myocardial perfusion scintigraphies were performed. By using 3 different cardiac quantification programs (ECTb, QGS, and Myometrix); LVEF, EDV, and ESV were calculated. The same raw data of MPS images were reprocessed at different time periods, and these 3 parameters were recalculated. LVEF, EDV, and ESV yielded by 3 different programs were compared for interprogram variability assessment, and parameters calculated at two different time periods were compared to evaluate intraprogram reproducibility. There were statistically significant differences between ECTb, QGS, and Myometrix programs for LVEF, EDV, and ESV (p0.05, r=0.09). Statistically significant differences were not found between the values of LVEF, EDV, and ESV obtained from the first and second reconstruction analysis of 3 cardiac quantification programs. Different MPS cardiac software programs give variable (but correlated) LVEF and left ventricular volumetric measures. Those obtained from different cardiac softwares cannot be used interchangeably. Our findings have shown that ECTb, QGS, and Myometrix programs are reproducible, with respect to LVEF, EDV, and ESV. (author)

    Nanoparticles (NPs) exhibit a number of distinctive and entrancing properties that explain their ever increasing application in analytical chemistry, mainly as chemosensors, signaling tags, catalysts, analytical signal enhancers, reactive species generators, analyte recognition and scavenging/separation entities. The prospect of associating NPs with automated flow-based analytical is undoubtedly a challenging perspective as it would permit confined, cost-effective and reliable analysis, within a shorter timeframe, while exploiting the features of NPs. This article aims at examining state-of-the-art on continuous flow analysis and microfluidic approaches involving NPs such as noble metals (gold and silver), magnetic materials, carbon, silica or quantum dots. Emphasis is devoted to NP format, main practical achievements and fields of application. In this context, the functionalization of NPs with distinct chemical species and ligands is debated in what concerns the motivations and strengths of developed approaches.

  1. Design of microcontroller based system for automation of streak camera

    International Nuclear Information System (INIS)

    A microcontroller based system has been developed for automation of the S-20 optical streak camera, which is used as a diagnostic tool to measure ultrafast light phenomenon. An 8 bit MCS family microcontroller is employed to generate all control signals for the streak camera. All biasing voltages required for various electrodes of the tubes are generated using dc-to-dc converters. A high voltage ramp signal is generated through a step generator unit followed by an integrator circuit and is applied to the camera's deflecting plates. The slope of the ramp can be changed by varying values of the capacitor and inductor. A programmable digital delay generator has been developed for synchronization of ramp signal with the optical signal. An independent hardwired interlock circuit has been developed for machine safety. A LABVIEW based graphical user interface has been developed which enables the user to program the settings of the camera and capture the image. The image is displayed with intensity profiles along horizontal and vertical axes. The streak camera was calibrated using nanosecond and femtosecond lasers.

  2. A Retroactive-Burst Framework for Automated Intrusion Response System

    2013-01-01

    Full Text Available The aim of this paper is to present an adaptive and cost-sensitive model to prevent security intrusions. In most automated intrusion response systems, response selection is performed locally based on current threat without using the knowledge of attacks history. Another challenge is that a group of responses are applied without any feedback mechanism to measure the response effect. We address these problems through retroactive-burst execution of responses and a Response Coordinator (RC mechanism, the main contributions of this work. The retroactive-burst execution consists of several burst executions of responses with, at the end of each burst, a mechanism for measuring the effectiveness of the applied responses by the risk assessment component. The appropriate combination of responses must be considered for each burst execution to mitigate the progress of the attack without necessarily running the next round of responses, because of the impact on legitimate users. In the proposed model, there is a multilevel response mechanism. To indicate which level is appropriate to apply based on the retroactive-burst execution, we get help from a Response Coordinator mechanism. The applied responses can improve the health of Applications, Kernel, Local Services, Network Services, and Physical Status. Based on these indexes, the RC gives a general overview of an attacker’s goal in a distributed environment.

  4. Automated logic conversion method for plant controller systems

    International Nuclear Information System (INIS)

    An automated method is proposed for logic conversion from functional description diagrams to detailed logic schematics by incorporating expertise knowledge in plant controller systems design. The method uses connection data of function elements in the functional description diagram as input, and synthesizes a detailed logic structure by adding elements to the given connection data incrementally, and to generate detailed logic schematics. In logic synthesis, for building up complex synthesis procedures by combining generally-described knowledge, knowledge is applied by groups. The search order of the groups is given by upper-level knowledge. Furthermore, the knowledge is expressed in terms of two classes of rules; one for generating a hypothesis of individual synthesis operations and the other for considering several hypotheses to determine the connection ordering of elements to be added. In the generation of detailed logic schematics, knowledge is used as rules for deriving various kinds of layout conditions on schematics, and rules for generating two-dimensional coordinates of layout objects. Rules in the latter class use layout conditions to predict intersections among layout objects without their coordinates being fixed. The effectiveness of the method with 150 rules was verified by its experimental application to some logic conversions in a real power plant design. Evaluation of the results showed them to be equivalent to those obtained by well qualified designers. (author)

    2015-12-01

    Full Text Available A desirable characteristic of programming code assessment is to provide the learner the most appropriate information regarding the code functionality as well as a chance to improve. This can be hardly achieved in case the number of learners is high (500 or more. In this paper we address the problem of risky code testing and availability of an assessment platform Arena, dealing with potential security risks when providing an automated assessment for a large set of source code. Looking at students’ programs as if they were potentially malicious inspired us to investigate separated execution environments, used by security experts for secure software analysis. The results also show that availability issues of our assessment platform can be conveniently resolved with task queues. A special attention is paid to Docker, a virtual container ensuring no risky code can affect the assessment system security. The assessment platform Arena enables to regularly, effectively and securely assess students' source code in various programming courses. In addition to that it is a motivating factor and helps students to engage in the educational process.

  7. An automated system for measuring parameters of nematode sinusoidal movement

    Directory of Open Access Journals (Sweden)

    Stirbl Robert C

    2005-02-01

    Full Text Available Abstract Background Nematode sinusoidal movement has been used as a phenotype in many studies of C. elegans development, behavior and physiology. A thorough understanding of the ways in which genes control these aspects of biology depends, in part, on the accuracy of phenotypic analysis. While worms that move poorly are relatively easy to describe, description of hyperactive movement and movement modulation presents more of a challenge. An enhanced capability to analyze all the complexities of nematode movement will thus help our understanding of how genes control behavior. Results We have developed a user-friendly system to analyze nematode movement in an automated and quantitative manner. In this system nematodes are automatically recognized and a computer-controlled microscope stage ensures that the nematode is kept within the camera field of view while video images from the camera are stored on videotape. In a second step, the images from the videotapes are processed to recognize the worm and to extract its changing position and posture over time. From this information, a variety of movement parameters are calculated. These parameters include the velocity of the worm's centroid, the velocity of the worm along its track, the extent and frequency of body bending, the amplitude and wavelength of the sinusoidal movement, and the propagation of the contraction wave along the body. The length of the worm is also determined and used to normalize the amplitude and wavelength measurements. To demonstrate the utility of this system, we report here a comparison of movement parameters for a small set of mutants affecting the Go/Gq mediated signaling network that controls acetylcholine release at the neuromuscular junction. The system allows comparison of distinct genotypes that affect movement similarly (activation of Gq-alpha versus loss of Go-alpha function, as well as of different mutant alleles at a single locus (null and dominant negative alleles

  8. Sensor concentrator unit for the Continuous Automated Vault Inventory System

    International Nuclear Information System (INIS)

    The purpose of this document is to describe the use and operation of the sensor concentrator in the Continuous Automated Vault Inventory System (CAVIS). The CAVIS electronically verifies the presence of items of stored special nuclear material (SNM). US Department of Energy orders require that stored SNM be inventoried periodically to provide assurance that the material is secure. Currently this inventory is a highly manual activity, requiring personnel to enter the storage vaults. Using a CAVIS allows the frequency of physical inventories to be significantly reduced, resulting in substantial cost savings, increased security, and improved safety. The electronic inventory of stored SNM requires two different types of sensors for each item. The two sensors measure different parameters of the item, usually weight and gamma rays. A CAVIS is constructed using four basic system components: sensors, sensor concentrators, a data collection unit, and a database/user interface unit. One sensor concentrator supports the inventory of up to 20 items (40 sensors) and continuously takes readings from the item sensors. On request the sensor concentrator outputs the most recent sensor readings to the data collection unit. The information transfer takes place over a RS485 communications link. The data collection unit supports from 1 to 120 sensor concentrators (1 to 2,400 items) and is referred to as the Sensor Polling and Configuration System (SPCS). The SPCS is connected by a secure Transmission Control Protocol/Internet Protocol (TCP/IP) network to the database/user interface unit, which is referred to as the Graphical Facility Information Center (GraFIC). A CAVIS containing more than 2,400 items is supported by connecting additional SPCS units to the GraFIC

  9. Towards a characterization of information automation systems on the flight deck

    Science.gov (United States)

    Dudley, Rachel Feddersen

    This thesis summarizes research to investigate the characteristics that define information automation systems used on aircraft flight decks and the significant impacts that these characteristics have on pilot performance. Major accomplishments of the work include the development of a set of characteristics that describe information automation systems on the flight deck and an experiment designed to study a subset of these characteristics. Information automation systems on the flight deck are responsible for the collection, processing, analysis, and presentation of data to the flightcrew. These systems pose human factors issues and challenges that must be considered by designers of these systems. Based on a previously developed formal definition of information automation for aircraft flight deck systems, an analysis process was developed and conducted to reach a refined set of information automation characteristics. In this work, characteristics are defined as a set of properties or attributes that describe an information automation system's operation or behavior, which can be used to identify and assess potential human factors issues. Hypotheses were formed for a subset of the characteristics: Automation Visibility, Information Quality, and Display Complexity. An experimental investigation was developed to measure performance impacts related to these characteristics, which showed mixed results of expected and surprising findings, with many interactions. A set of recommendations were then developed based on the experimental observations. Ensuring that the right information is presented to pilots at the right time and in the appropriate manner is the job of flight deck system designers. This work provides a foundation for developing recommendations and guidelines specific to information automation on the flight deck with the goal of improving the design and evaluation of information automation systems before they are implemented.

    In recent years, two automated systems have been developed that add derivative taking capability to existing FORTRAN codes. The derivative information is used to calculate sensitivities of model results to input data. The two systems, GRESS and ADGEN, solve the forward and adjoint sensitivity problems, respectively. Both systems are based on a precompiler that automates the calculation of derivatives of the real variable on the left-hand-side (LHS) of each equation with respect to the real variables on the right-hand-side (RHS) of each equation. This paper describes the features of the extended arithmetic processor (EXAP) precompiler that makes the automation of differentiation capability practical

    Summary: The effect of the autonomic nerves on the transmural dispersion of ventricular repolarization in intact canine was investigated. By using the monophasic action potential (MAP) recording technique, monophasic action potentials (MAPs) of the epicardium (Epi), midmyocardium (Mid)and endocardium (Endo) were recorded simultaneously by specially designed plunge-needle electrodes at the left ventricular free wall in 12 open-chest dogs. MAPD90 and transmural dispersion of repolarization among three myocardial layers as well as the incidence of the EAD before autonomic nervous stimulation and during autonomic nervous stimulation were compared. The results showed that the MAPD90 of Epi, Mid and Endo before autonomic nervous stimulation were 278±11 ms,316± 16 ms and 270± 12 ms respectively, the MAPD90of Mid was significantly longer than that of Epi or Endo (P<0.01). MAPD90 of Epi, Mid and Endo were shortened by 19±4 ms, 45±6 ms,18± 3 ms respectively during sympathetic stimulation. Compared with that of the control, the transmural dispersion of repolarization during sympathetic stimulation was shortened from 44 ± 4 ms to 15±3 ms (P<0. 01), but early afterdepolarizations were elicited in the Mid of 5 dogs (41 0%)during sympathetic stimulation. Parasympathetic stimulation did not significantly affect the MAPD90 in the three layers. It is concluded that there is the transmural dispersion of ventricular repolarization in intact canine. Sympathetic stimulation can reduce transmural dispersion of repolarization, but it can produce early afterdepolarizations in the Mid. Parasympathetic stimulation does not significantly affect the transmural dispersion of ventricular repolarization.

  14. Automated simulation integration supporting digital control system upgrade projects

    International Nuclear Information System (INIS)

    huge drain on simulator maintenance resources if left to be done manually. A unique proposal was put forward to write a code generator that could automatically translate the control system configuration into standard simulator code modules. The code generator has been developed and the Bruce Power simulator team has commissioned the new auto-generated turbine governor control emulation models. Using this automated simulator integration approach, the Bruce Power simulator team plans to integrate subsequent digital control system software prior to field installation to reduce the risk of unforeseen commissioning and operational problems.

    Patients with systemic sclerosis (SS) have cardiac dysfunction induced by cold exposure. We and others have demonstrated this finding after corporal chilling, suggesting a "coronary Raynaud phenomenon" mediated by intermittent vascular spasm. In this study we evaluated the effect of diltiazem (DTZ) in cardiac dysfunction induced by cold test in patients with SS without clinical evidence of heart disease. Twelve patients with SS were studied. One patient was excluded because he did not fulfill the prescribed treatment. Eleven patients (age of 49.9 +/- 3.8 years and illness duration of 9.3 +/- 4.8 years) were included. Gated equilibrium radionuclide ventriculography was recorded after red blood cells were labeled in vivo using an intravenous injection of stannous pirophosphate followed by 20 mc of 99 Tc (gamma camera with electrocardiographic R wave gating was used). Left ventricular injection fraction (LVEF) was calculated using computer analysis and wall motion abnormalities by visual interpretation. Patients were cooled using a thermic blanket set at 5 degrees centigrade. They were evaluated before and after a period of cooling. After corporal chilling LVEF decreased more than 10% in all of them. DTZ 270 mg a day was administered to the same patients during 48 hs. Basal and cold LVEF were repeated in all patients. The results with and without DTZ were compared by Student's t Test. The basal LVEF with and without DTZ was not different (64.8 +/- 2.6 and 63.1 +/- 1.8). After corporal chilling LVEF decreased (64.8 +/- 2.6 to 54.8 +/- 2.5 p < 0.00001) and reversible abnormalities in wall motion were noticed in patients without DTZ. When they received DTZ neither difference in LVEF (63.1 +/- 1.8 to 62.1 +/- 2.4) nor wall motion abnormalities were observed. We compared the LVEF after chilling (62.1 +/- 2.4 and 54.8 +/- 2.5) and we found an important difference with the use of DTZ (p < 0.005). It can be concluded that in patients with SS and no overt heart disease, DTZ

  16. The SushiBar: An automated system for paleomagnetic investigations

    2012-04-01

    We present a new, automated system based on a three-axis superconducting magnetometer and a custom-made coil designed to experiment on cylindrical specimens used in typical paleomagnetic investigations. The system, which resembles a sushi bar, facilitates stepwise alternating field demagnetization of up to 99 samples per loaded track. It also enables researchers to explore magnetic properties using an anhysteretic remanent magnetization (ARM) in any coercivity window up to peak alternating fields of 95 mT with direct current bias fields up to 0.17 mT. For example, partial ARM (pARM) spectra characterize magnetic grain size distributions in rocks, yet rarely are pARM spectra measured because the complete curve for one sample takes at least two hours to acquire manually. The SushiBar achieves 99 such curves in slightly less than 100 hours. Using the SushiBar, we measured the pARM sprectra, as well as the viscosity and anisotropy of ARM in three discrete switching field windows, of continental sediments from the Xishuigou section (western China). The average grain size remains constant along the 2200 m-thick section, yet magnetic viscosity varies systematically from bottom to top of the section; samples with high magnetic viscosities also have higher proportions of non-viscous material on average. Principal anisotropy axis directions from the lowest switching fields correlate well with principal axis directions from anisotropy of magnetic susceptibility. Principal axis directions defined at higher switching fields systematically deviate from those at lower switching fields, perhaps defining the fabric of the remanence carrying grains.

    The integration of Wireless Sensors Networks (WSNs) into Cyber Physical Systems (CPSs) is an important research problem to solve in order to increase the performances, safety, reliability and usability of wireless automation systems. Due to the complexity of real CPSs, emulators and simulators are often used to replace the real control devices and physical connections during the development stage. The most widespread simulators are free, open source, expandable, flexible and fully integrated into mathematical modeling tools; however, the connection at a physical level and the direct interaction with the real process via the WSN are only marginally tackled; moreover, the simulated wireless sensor motes are not able to generate the analogue output typically required for control purposes. A new simulation module for the control of a wireless cyber-physical system is proposed in this paper. The module integrates the COntiki OS JAva Simulator (COOJA), a cross-level wireless sensor network simulator, and the LabVIEW system design software from National Instruments. The proposed software module has been called "GILOO" (Graphical Integration of Labview and cOOja). It allows one to develop and to debug control strategies over the WSN both using virtual or real hardware modules, such as the National Instruments Real-Time Module platform, the CompactRio, the Supervisory Control And Data Acquisition (SCADA), etc. To test the proposed solution, we decided to integrate it with one of the most popular simulators, i.e., the Contiki OS, and wireless motes, i.e., the Sky mote. As a further contribution, the Contiki Sky DAC driver and a new "Advanced Sky GUI" have been proposed and tested in the COOJA Simulator in order to provide the possibility to develop control over the WSN. To test the performances of the proposed GILOO software module, several experimental tests have been made, and interesting preliminary results are reported.

    Full Text Available OBJECTIVES: We evaluated the impairment of endothelium-dependent and endothelium-independent coronary blood flow reserve after administration of intracoronary acetylcholine and adenosine, and its association with hypertensive cardiac disease. INTRODUCTION: Coronary blood flow reserve reduction has been proposed as a mechanism for the progression of compensated left ventricular hypertrophy to ventricular dysfunction. METHODS: Eighteen hypertensive patients with normal epicardial coronary arteries on angiography were divided into two groups according to left ventricular fractional shortening (FS. Group 1 (FS >0.25: n=8, FS=0.29 ± 0.03; Group 2 (FS <0.25: n=10, FS= 0.17 ± 0.03. RESULTS: Baseline coronary blood flow was similar in both groups (Group 1: 80.15 ± 26.41 mL/min, Group 2: 100.09 ± 21.51 mL/min, p=NS. In response to adenosine, coronary blood flow increased to 265.1 ± 100.2 mL/min in Group 1 and to 300.8 ± 113.6 mL/min (p <0.05 in Group 2. Endothelium-independent coronary blood flow reserve was similar in both groups (Group 1: 3.31 ± 0.68 and Group 2: 2.97 ± 0.80, p=NS. In response to acetylcholine, coronary blood flow increased to 156.08 ± 36.79 mL/min in Group 1 and to 177.8 ± 83.6 mL/min in Group 2 (p <0.05. Endothelium-dependent coronary blood flow reserve was similar in the two groups (Group 1: 2.08 ± 0.74 and group Group 2: 1.76 ± 0.61, p=NS. Peak acetylcholine/peak adenosine coronary blood flow response (Group 1: 0.65 ± 0.27 and Group 2: 0.60 ± 0.17 and minimal coronary vascular resistance (Group 1: 0.48 ± 0.21 mmHg/mL/min and Group 2: 0.34 ± 0.12 mmHg/mL/min were similar in both groups (p= NS.

    1989-01-01

    A transcutaneous energy transmission system (TETS) has been used to power the Penn State motor driven ventricular assist device in nine calf experiments, for a total of 316 days of cumulative in vivo experience. This is seen as an important step toward a completely implantable ventricular assist system and total artificial heart. The TETS converts an external 12 volt DC source via inductive coupling to a regulated 14 volt output voltage for use by the motor controller. A maximum output power of 70 watts is available. In calf experiments, the TETS output power averaged between 8 and 12 watts. The motor controller was not implanted in these experiments, awaiting further development of the miniaturized electronics. The TETS output was returned percutaneously to the external motor controller, allowing the TETS output to be monitored directly. System efficiency, from DC source to DC output, and including losses in 12 feet of cable, ranged from 55% to 70%, depending upon supply voltage, motor load, and degree of coil coupling. The subcutaneous coil was well tolerated, demonstrating only temporary, mild, superficial induration. PMID:2597465

    In the power distribution department of Chubu Electric Company, the automation system based on a computer has been introduced into 42 offices that are about 50% of the whole office and about 4000 lines that are 46% of the whole distribution line by the end of 1996. In this paper, the present situation and future trend of this line automation system are described. The automation system of a distribution line enables the remote monitor and control of a section switch and provides the information required for the operation control of a line voltage in the remote location. Especially, the substation equipment is located under severe environment (e.g., in the open air or on a telegraph post), so it has high reliability, a self-diagnosis function, and a fail-safe function against lightning surge, external noise, temperature change, and rain water. The main station system aims at wide-area cooperation and automatic flexibility while considering the correspondence to the future function expansion. Each server system is applied to optical fiber WAN so as to obtain the desired results. In future, positive development will be promoted corresponding to the distributed power supply. 4 refs., 5 figs., 2 tabs.

    Current designs of underground nuclear waste repositories have not adequately addressed the possibility of automated, unmanned emplacement and retrieval. This report will present design methodologies for development of an automated system for underground emplacement of nuclear waste. By scaling generic issues to different repositories, it is shown that a two vehicle automated waste emplacement/retrieval system can be designed to operate in a fail-safe mode. Evaluation of cost at this time is not possible. Significant gains in worker safety, however, can be realized by minimizing the possibility of human exposure

    Madsen, K.

    2013-12-01

    Geographic Information Systems (GIS) have many applications in the hydrological sciences. However, GIS software is often expensive and difficult to automate. This paper will demonstrate how to automate GRASS GIS software using the Python programming language. Both GRASS GIS and Python are open source projects that are free for anyone to use. Automation of GIS processes is important when dealing with large-scale geographic studies, as large GIS maps are usually divided into discrete tiles. When conducting GIS transformations on such maps, the user must repeat the action for each tile, a process that is greatly expedited through automation. The paper will work through several examples of automated GIS processes and provide complete Python codes that demonstrate correct syntax for working with GRASS GIS applications. The provided examples will demonstrate automation of the following processes 1.) using raster math to calculate foliage thickness from LIDAR and DEM data; 2.) conducting raster interpolation from a set of vector points to develop a continuous hydraulic conductivity coverage; 3.) automating raster coloration to sync the coloration of a large number of raster tiles for website display, and 4.) constructing contoured vector lines from topography rasters. These examples programs will serve as the building blocks for readers, giving them the tools to automate any GIS process using Python and GRASS GIS.

    This book describes a novel approach for the design of embedded systems and industrial automation systems, using a unified model-driven approach that is applicable in both domains.  The authors illustrate their methodology, using the IEC 61499 standard as the main vehicle for specification, verification, static timing analysis and automated code synthesis.  The well-known synchronous approach is used as the main vehicle for defining an unambiguous semantics that ensures determinism and deadlock freedom. The proposed approach also ensures very efficient implementations either on small-scale embedded devices or on industry-scale programmable automation controllers (PACs). It can be used for both centralized and distributed implementations. Significantly, the proposed approach can be used without the need for any run-time support. This approach, for the first time, blurs the gap between embedded systems and automation systems and can be applied in wide-ranging applications in automotive, robotics, and industri...

    2008-01-01

    This slide presentation reviews some of the issues concerning verification and validation testing of autonomous spacecraft routinely culminates in the exploration of anomalous or faulted mission-like scenarios using the work involved during the Dawn mission's tests as examples. Prioritizing which scenarios to develop usually comes down to focusing on the most vulnerable areas and ensuring the best return on investment of test time. Rules-of-thumb strategies often come into play, such as injecting applicable anomalies prior to, during, and after system state changes; or, creating cases that ensure good safety-net algorithm coverage. Although experience and judgment in test selection can lead to high levels of confidence about the majority of a system's autonomy, it's likely that important test cases are overlooked. One method to fill in potential test coverage gaps is to automatically generate and execute test cases using algorithms that ensure desirable properties about the coverage. For example, generate cases for all possible fault monitors, and across all state change boundaries. Of course, the scope of coverage is determined by the test environment capabilities, where a faster-than-real-time, high-fidelity, software-only simulation would allow the broadest coverage. Even real-time systems that can be replicated and run in parallel, and that have reliable set-up and operations features provide an excellent resource for automated testing. Making detailed predictions for the outcome of such tests can be difficult, and when algorithmic means are employed to produce hundreds or even thousands of cases, generating predicts individually is impractical, and generating predicts with tools requires executable models of the design and environment that themselves require a complete test program. Therefore, evaluating the results of large number of mission scenario tests poses special challenges. A good approach to address this problem is to automatically score the results

    Objective To evaluate the value of automated threshold-based segmentation method in compari-son with Simpson method for measurement of left ventricular (LV) function in Philips 256 iCT. Methods Forty eight patients with known or suspected coronary artery disease underwent coronary CT angiography. End-systolic volume (ESV), end-diastolic volume (EDV), stroke volume (SV), ejection fraction (EF) and left ventricular myocardial mass (LVMM) at end diastole were post-processed separately by Simpson method and automated threshold-based segmenta-tion method. Statistical methods used included paired t test, Person correlation analysis and Bland-Altman analysis. Results Automated threshold-based segmentation method had significant correlation with Simpson method for mea-surement of left ventricular function, and the r values of ESV, EDV, SV, EF, LVMM were 0.996, 0.998, 0.982, 0.986, 0.988, respectively. Bland-Altman analysis showed that the mean difference of ESV, EDV, SV, EF, LVMM between Simpson method and automated threshold-based segmentation method were 1.4 ml, 3.2 ml, 1.8 ml, 0.0%,-10.3 g. Comparison of Simpson method, automated threshold-based segmentation method and echocardiography showed EF value with P>0.05 and SV value with P0.05,SV值<0.01。结论 iCT测量左心室功能无创、准确、可靠,Simpson法、Threshold-Based Segmentation法测量左心功能具有较好的一致性,临床上推荐采用Simpson法进行心脏功能评估。

    Feary, Michael S.; Roth, Emilie

    2014-01-01

    Increasing amounts of automation are being introduced to safety-critical domains. While the introduction of automation has led to an overall increase in reliability and improved safety, it has also introduced a class of failure modes, and new challenges in risk assessment for the new systems, particularly in the assessment of rare events resulting from complex inter-related factors. Designing successful human-automation systems is challenging, and the challenges go beyond good interface development (e.g., Roth, Malin, & Schreckenghost 1997; Christoffersen & Woods, 2002). Human-automation design is particularly challenging when the underlying automation technology generates behavior that is difficult for the user to anticipate or understand. These challenges have been recognized in several safety-critical domains, and have resulted in increased efforts to develop training, procedures, regulations and guidance material (CAST, 2008, IAEA, 2001, FAA, 2013, ICAO, 2012). This paper points to the continuing need for new methods to describe and characterize the operational environment within which new automation concepts are being presented. We will describe challenges to the successful development and evaluation of human-automation systems in safety-critical domains, and describe some approaches that could be used to address these challenges. We will draw from experience with the aviation, spaceflight and nuclear power domains.

    Two experiments are presented that examine alternative methods for invoking automation. In each experiment, participants were asked to perform simultaneously a monitoring task and a resource management task as well as a tracking task that changed between automatic and manual modes. The monitoring task required participants to detect failures of an automated system to correct aberrant conditions under either high or low system reliability. Performance on each task was assessed as well as situation awareness and subjective workload. In the first experiment, half of the participants worked with a brain-based system that used their EEG signals to switch the tracking task between automatic and manual modes. The remaining participants were yoked to participants from the adaptive condition and received the same schedule of mode switches, but their EEG had no effect on the automation. Within each group, half of the participants were assigned to either the low or high reliability monitoring task. In addition, within each combination of automation invocation and system reliability, participants were separated into high and low complacency potential groups. The results revealed no significant effects of automation invocation on the performance measures; however, the high complacency individuals demonstrated better situation awareness when working with the adaptive automation system. The second experiment was the same as the first with one important exception. Automation was invoked manually. Thus, half of the participants pressed a button to invoke automation for 10 s. The remaining participants were yoked to participants from the adaptable condition and received the same schedule of mode switches, but they had no control over the automation. The results showed that participants who could invoke automation performed more poorly on the resource management task and reported higher levels of subjective workload. Further, those who invoked automation more frequently performed

    The APD software features include: On-line help, Three level architecture, (Logic environments, Setup/Application environment, Data environment), Explanation capability, and File handling. The kinds of experimentation and record keeping that leads to effective expert systems is facilitated by: (1) a library of inferencing modules (in the logic environment); (2) an explanation capability which reveals logic strategies to users; (3) automated file naming conventions; (4) an information retrieval system; and (5) on-line help. These aid with effective use of knowledge, debugging and experimentation. Since the APD software anticipates the logical rules becoming complicated, it is embedded in a production system language (CLIPS) to insure the full power of the production system paradigm of CLIPS and availability of the procedural language C. The development is discussed of the APD software and three example applications: toy, experimental, and operational prototype for submarine maintenance predictions.

    Long duration human space missions, as planned in the Vision for Space Exploration, will not be possible without applying unprecedented levels of automation to support the human endeavors. The automated and robotic systems must carry the load of routine housekeeping for the new generation of explorers, as well as assist their exploration science and engineering work with new precision. Fortunately, the state of automated and robotic systems is sophisticated and sturdy enough to do this work - but the systems themselves have never been human-rated as all other NASA physical systems used in human space flight have. Our intent in this paper is to provide perspective on requirements and architecture for the interfaces and interactions between human beings and the astonishing array of automated systems; and the approach we believe necessary to create human-rated systems and implement them in the space program. We will explain our proposed standard structure for automation and robotic systems, and the process by which we will develop and implement that standard as an addition to NASA s Human Rating requirements. Our work here is based on real experience with both human system and robotic system designs; for surface operations as well as for in-flight monitoring and control; and on the necessities we have discovered for human-systems integration in NASA's Constellation program. We hope this will be an invitation to dialog and to consideration of a new issue facing new generations of explorers and their outfitters.

    Full Text Available Abstract Background Induced pluripotent stem (iPS cells can differentiate into any cell type, which makes them an attractive resource in fields such as regenerative medicine, drug screening, or in vitro toxicology. The most important prerequisite for these industrial applications is stable supply and uniform quality of iPS cells. Variation in quality largely results from differences in handling skills between operators in laboratories. To minimize these differences, establishment of an automated iPS cell culture system is necessary. Results We developed a standardized mouse iPS cell maintenance culture, using an automated cell culture system housed in a CO2 incubator commonly used in many laboratories. The iPS cells propagated in a chamber uniquely designed for automated culture and showed specific colony morphology, as for manual culture. A cell detachment device in the system passaged iPS cells automatically by dispersing colonies to single cells. In addition, iPS cells were passaged without any change in colony morphology or expression of undifferentiated stem cell markers during the 4 weeks of automated culture. Conclusions Our results show that use of this compact, automated cell culture system facilitates stable iPS cell culture without obvious effects on iPS cell pluripotency or colony-forming ability. The feasibility of iPS cell culture automation may greatly facilitate the use of this versatile cell source for a variety of biomedical applications.

    2004-02-01

    The University of Dayton Research Institute (UDRI) under contract by the US Air Force has designed and constructed a fully automated ultrasonic inspection system for the detection of embedded defects in rotating gas turbine engine components. The system performs automated inspections using the "scan plan" concept developed for the Air Force sponsored "Retirement For Cause" (RFC) automated eddy current system. Execution of the scan plan results in a fully automated inspection process producing engine component accept/reject decisions based on probability of detection (POD) information. Use of the phased-array ultrasonic instrument and probes allows for optimization of both the sensitivity and resolution for each inspection through electronic beamforming, scanning, and focusing processes. However, issues such as alignment of the array probe, calibration of individual elements and overall beam response prior to the inspection have not been addressed for an automated system. This paper will discuss current progress in the development of an automated alignment and calibration procedure for various phased array apertures and specimen geometries.

    Full Text Available Bug Triage is an important aspect of Open Source Software Development. Automated Bug Triage system is essential to reduce the cost and effort incurred by manual Bug Triage. At present, the metrics that are available in the literature to evaluate the Automated Bug Triage System are only recommendation centric. These metrics address only the correctness and coverage of the Automated Bug Triage System. Thus, there is a need for user-centric evaluation of the Bug Triage System. The two types of metrics to evaluate the Automated Bug Triage System include Recommendation Metrics and User Metrics. There is a need to corroborate the results produced by the Recommendation Metrics with User Metrics. To this end, this paper furnishes a Holistic Evaluation Framework for Bug Triage System by integrating the developer performance into the evaluation framework. The Automated Bug Triage System is also to retrieve a set of developers for resolving a bug. Hence, this paper proposes Key Performance Indicators (KPI for appraising a developer’s effectiveness in contribution towards the resolution of the bug. By applying the KPIs on the retrieved set of developers, the Bug Triage System can be evaluated quantitatively.

  5. Quantitative reliability assessment in the safety case of computer-based automation systems

    International Nuclear Information System (INIS)

    An essential issue in the construction of new or in the replacement of the old analogue automation applications in nuclear power plants is the reliability of computer-based systems, and especially the question of how to assess their reliability. The reliability issue is particularly important when the system under assessment is considered as a safety-critical system, such as the reactor protection system. To build sufficient confidence on the reliability of computer-based systems appropriate reliability assessment methods should be developed and applied. The assessment methods should provide useful and plausible reliability estimates, while taking the special characteristics of the reliability assessment of computer-based systems into consideration. The Bayesian inference has proved to be an efficient methodology in the reliability assessment of computer-based automation applications. Practical implementation of Bayesian inference, Bayesian networks, allow the combination of the different safety arguments concerning the system and its development process to a unified reliability estimate. Bayesian networks are also a convenient way to communicate on the safety argumentation between various participants of systems design and implementation as well as between the participants in the licensing processes of computer-based automation systems. This study is a part of the research project 'Programmable Automation System Safety Integrity assessment (PASSI)', belonging to the Finnish Nuclear Safety Research Programme (FINNUS, 1999-2002). The project aimed to provide support for the authorities and utilities in the licensing problems of computer-based automation systems. Particular objective of the project was to acquire, develop and test new and more cost-effective methods and tools for the safety and reliability assessment, and to gather practical experience on their use in order to achieve a more streamlined licensing process for the computer- based automation systems

    Schulze, L.; Behling, S.; Buhrs, S.

    2008-06-01

    The usage of Automated Guided Vehicle Systems (AGVS) is growing. This has not always been the case in the past. A new record of the sells numbers is the result of inventive developments, new applications and modern thinking. One market that AGVS were not able to thoroughly conquer yet were rapidly changing logistics environments. The advantages in recurrent transportation with AGVS used to be hindered by the needs of flexibility. When nowadays managers talk about Flexible Manufacturing Systems (FMS) there is no reason not to consider AGVS. Fixed guidelines, permanent transfer stations and static routes are no necessity for most AGVS producers. Flexible Manufacturing Systems can raise profitability with AGVS. When robots start saving billions in production costs, the next step at same plants are automated materials handling systems. Today, there are hundreds of instances of computer-controlled systems designed to handle and transport materials, many of which have replaced conventional human-driven platform trucks. Reduced costs due to damages and failures, tracking and tracing as well as improved production scheduling on top of fewer personnel needs are only some of the advantages.
