    Small volume fluid handling in single and multiphase microfluidics provides a promising strategy for efficient bio-chemical assays, low-cost point-of-care diagnostics and new approaches to scientific discoveries. However multiple barriers exist towards low-cost field deployment of programmable microfluidics. Incorporating multiple pumps, mixers and discrete valve based control of nanoliter fluids and droplets in an integrated, programmable manner without additional required external components has remained elusive. Combining the idea of punch card programming with arbitrary fluid control, here we describe a self-contained, hand-crank powered, multiplex and robust programmable microfluidic platform. A paper tape encodes information as a series of punched holes. A mechanical reader/actuator reads these paper tapes and correspondingly executes a series of operations onto a microfluidic chip coupled to the platform in a plug-and-play fashion. Enabled by the complexity of codes that can be represented by a series ...

    It is reported that for the purpose of increasing the operability of work related to hygiene-dosimetric control, a manual information searching system using punched cards is located at a health physics station. The cards contain passport data for the object, its brief hygenic-technological data, indications of anomalous cases, radioactive fall-out, etc. The results are recorded of inspections, reflecting quantity and nature of disturbances that develop, dosimetry data, information from personnel and medical examinations, etc. (V.A.P.)

  6. Application at Marcoule of Punched-Card Techniques to Problems of Programming Reactor Unloading During Operation

    International Nuclear Information System (INIS)

    Continuous unloading during operation presents special problems for the unloading programme - problems far more complex than when the reactor is unloaded during shutdown. The yield of the fuel is linked with the homogenization of its irradiation and this in turn is a function of the radial and the axial flux. Axial homogenization of the irradiation depends on the method of unloading. In reactors that can be unloaded during operation it can be achieved under more favourable conditions than in reactors that must be unloaded during shut-down. In reactors unloaded during operation, radial homogenization of the irradiation results from the execution of an unloading programme established per channel - not per zone, as in reactors unloaded during shut-down. The unloading programmes are prepared at the Marcoule Centre by a punched-card machine - electronic computer system, which also carries out various accessory operations connected with the functioning of the reactors and control of the fuel.

  7. From Punched Cards to "Big Data": A Social History of Database Populism

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available Since the diffusion of the punched card tabulator following the 1890 U.S. Census, mass-scale information processing has been alternately a site of opportunity, ambivalence and fear in the American imagination. While large bureaucracies have tended to deploy database technology toward purposes of surveillance and control, the rise of personal computing made databases accessible to individuals and small businesses for the first time. Today, the massive collection of trace communication data by public and private institutions has renewed popular anxiety about the role of the database in society. This essay traces the social history of database technology across three periods that represent significant changes in the accessibility and infrastructure of information processing systems. Although many proposed uses of "big data" seem to threaten individual privacy, a largely-forgotten database populism from the 1970s and 1980s suggests that a reclamation of small-scale data processing might lead to sharper popular critique in the future.

  8. Performance testing of a semi-automatic card punch system, using direct STR profiling of DNA from blood samples on FTA™ cards.

    2015-01-01

    The 1.2 mm Electric Coring Tool (e-Core™) was developed to increase the throughput of FTA(™) sample collection cards used during forensic workflows and is similar to a 1.2 mm Harris manual micro-punch for sampling dried blood spots. Direct short tandem repeat (STR) DNA profiling was used to compare samples taken by the e-Core tool with those taken by the manual micro-punch. The performance of the e-Core device was evaluated using a commercially available PowerPlex™ 18D STR System. In addition, an analysis was performed that investigated the potential carryover of DNA via the e-Core punch from one FTA disc to another. This contamination study was carried out using Applied Biosystems AmpflSTR™ Identifiler™ Direct PCR Amplification kits. The e-Core instrument does not contaminate FTA discs when a cleaning punch is used following excision of discs containing samples and generates STR profiles that are comparable to those generated by the manual micro-punch.

    Reinforced concrete flat slabs are a common structural system for cast-in-place concrete slabs. Failures in punching shear near the column regions are typically governing at ultimate. In case no punching shear or integrity reinforcement is placed, failures in punching develop normally in a brittle manner with almost no warning signs. Furthermore, the residual strength after punching is, in general, significantly lower than the punching load. Thus, punching of a single column of a flat slab ov...

    2014-01-01

    Full Text Available Background: Autologous mini punch grafting (MPG is a safe, effective and easy technique that can be performed on any site with minimal side effects and good cosmetic results. Large areas of stable generalised vitiligo require more grafts and are time consuming. Hence multiple sessions of surgery need to be scheduled. We share our experience of using motorised power punches to increase the speed of surgery in large areas of stable vitiligo in 10 patients. Materials and Methods: Ten patients in the age group of 12-55 years were treated with miniature punch grafting using power punches in single session on various sites. The power punches of 1-1.5 mm diameter were used to score donor and recipient sites, either of same or less than 0.2-0.3 mm size punches. The harvested grafts from donor site were then secured in the recipient beds and dressed. Results: The average number of grafts harvested per session was 125-185, the duration of surgery ranged from 45 to 90 minutes. Perigraft pigment spread was seen at 3 weeks. Complete repigmentation was observed in 3-4 months in eight patients. Cobble stoning was observed in one patient, and all donor sites healed well with superficial scarring. Conclusion: We conclude that autologous MPG with motorised power punches for stable vitiligo, especially on large areas including difficult sites can be performed with ease in comparatively lesser time in a single session, greatly benefiting the patients.

  3. Targeted cryotherapy using disposable biopsy punches

    Directory of Open Access Journals (Sweden)

    Avitus John Raakesh Prasad

    2014-01-01

    Full Text Available Cryotherapy is a commonly used office procedure that causes destruction of tissue by cryonecrosis due to rapid freezing and thawing of cells. The limitation in treating plantar warts and deeper dermal lesions is that the freeze time should be longer to penetrate deeper, which results in collateral damage to normal skin surrounding the lesion. This results in unwanted side effects of prolonged pain, blistering and haemorrhage and increased healing time. The cone spray technique was used to reduce collateral damage, but deeper penetration is difficult to achieve. An innovative technique using disposable biopsy punches is described that ensures deeper freezing as compared to the plastic cone. The metal cutting edge of the punch enters deeper into the lesions as the liquid nitrogen is passed, sparing damage to surrounding skin.

  4. The optimal clearance design of micro-punching die

    K.S. Lee

    2008-07-01

    Full Text Available Purpose: The purpose of this research paper is focused on the optimal clearance design of micro-punching die by abductive network and SA method.Design/methodology/approach: The punching data (input and wear size (output were collected for a training database. In order to select proper clearance to evaluate the wear of die, the abductive network was used to establish an efficient relationship between input parameters and output result. This can help to predict wear size under any degree of clearance and hence to replace worn punches and dies at the right time. A simulated annealing (SA optimization algorithm with a performance index is then applied to the neural network for searching the optimal clearance parameters, and obtains rather satisfactory result as compared with the corresponding experiment verification.Findings: This study aims to identify the relationship between clearance and service life of micro punches using the Neural Network, and to find relational data involving the service life of punches and punching parameters in non-metal blanking processes. The result can be used to estimate optimal clearance between punch and die for industrial applications.Research limitations/implications: In this study, the practical punching processes with different punching conditions were carried out for a set of training data. A trained model exhibited a relationship between service life and clearance of micro punch and die through an abductive network system. The predicted value of wear by abductive network is very close to the actual experimental value, with an error of less than 8%. This result satisfies the required standard for IC factory production.Originality/value: A good clearance design not only increases the quality of product manufactured, but also reduces product’s burr. As a result, the wear of punches and dies can be greatly reduced and the life expectancy of punching dies increased.

    Reinforced concrete flat slabs are extensively used in buildings and parking garages. Their design is governed by deflection at the serviceability limit state and punching shear at the ultimate limit state. When no punching shear reinforcement is provided, failure develops in a brittle manner.

  7. Small Punch Test Techniques for Irradiated Materials in Hot Cell

    International Nuclear Information System (INIS)

    Detailed procedures of the small punch test including the apparatus, the definition of small punch-related parameters, and the interpretation of results were presented. The testing machine should have a capability of the compressive loading and unloading at a given deflection level. The small punch specimen holder consists of an upper and lower die and clamping screws. The clamped specimen is deformed by using ball or spherical head punch. Two type of specimens with a circular and a square shape were used. The irradiated small punch specimen is made from the undamaged portion of the broken CVN bars or prepared by the irradiation of the specimen fabricated from the fresh materials. The heating and cooling devices should have the capability of the temperature control within ±2 .deg. C for the target value during the test. Based on the load-deflection data obtained from the small punch test. the empirical correlation between the small punch related parameters and a tensile properties such as 0.2% yield strength and ultimate tensile strength, fracture toughness, ductile-brittle transition temperature and creep properties determined from the standard test method is established and used to evaluate the mechanical properties of an irradiated materials. In addition, from the quantitative fractographic assessment of small punch test specimens, the relationship between the small punch energy and the quantity of ductile crack growth is obtained. Analytical formulations demonstrated good agreement with experimental load-deflection curves

Subjects were eight elite right-handed male (age 20.4 ± 2.1yrs; height 177.4 ± 8.5 cm; mass 70.4 ± 16.8 kg amateur boxers. 3D motion analysis was used to assess the kinematics of the right side extremities and head. Ensemble averaging of time normalized kinematic parameters was used to have better visual inspection. Results showed a similar pattern between subjects with some considerable variation in some parameters that pointed out to individualized pattern in elite boxers. Investigation of lower body joints kinematics explained boxers throw punch using leg drive. Stretch-shortening cycle detected in the technique implies potential for performance enhancing using plyometrics. Head velocity measured in anterior-posterior and medial-lateral direction would intensify potential head injuries.

  14. Gate oxide punching thru mechanism in plasma dry etching

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    The punching thru mechanism of gate oxide (thickness about 15A) was investi- gated. Because of the thin thickness of gate oxide, gate oxide punching thru may easily happen during the plasma process. It was found that what caused the punching thru was not only the selectivity of poly-silicon/oxide but also the pattern topography. We used the basic SRAM pattern to check this topography effect, and found that gate oxide located at the narrow spacing of two parallel serpentine lines was the most easily punched thru. What caused the topography effect was the starvation of oxygen in these places which were induced by the residue of poly-silicon and enhanced by electron shading effect. So, to solve the issue of gate oxide punching thru, firstly the selectivity should be enough, secondly we should pay attention to the etching pattern topography.

However, virtually single-handedly it also gave a body and emancipated culture to this otherwise socially abstract personality. Using illustrations from "Punch," this essay argues that using sport specific clothing and equipment in its cartoons, "Punch" completely unintentionally created a liberating picture of women while simultaneously using its captions and border texts to make the New Woman's body signify the anxieties patriarchal culture had about her social personality and politics.

The small punch creep curves show the three stages found in the creep curves of the conventional uniaxial test. The conventional creep relationships which involve parameters such as creep rate, stress, time to rupture and temperature were followed with the corresponding parameters of small punch creep test and they permitted to explain the creep behavior in this steel. The mechanism and activation energy of the deformation process were the grain boundary sliding and diffusion, respectively, during creep which caused the intergranular fracture in the tested specimens.

    Cutaneous leishmaniasis (CL) has been introduced to the Leishmania under-endemic Lebanese population in an uncontrolled manner as a result of recent large-scale displacement of refugees from endemic Syria. Accordingly, a quick and reliable method to diagnose CL is essential. Matched punch biopsies and air-dried scrapings on 72 patients were obtained. Scrapings were collected in two forms: thick drop (N = 33) or thin smear (N = 39). Clinical information was recorded. Sections of punch biopsies and scrapings were stained and examined microscopically. Polymerase chain reaction (PCR) was performed on both scraping forms and biopsies. The diagnostic sensitivity of the tests performed revealed that microscopy in conjunction with PCR on punch biopsies was the most sensitive test (93%) overall. However, taken individually, microscopy and PCR yielded the highest sensitivities when performed on drop scrapings (63% and 85%, respectively), and not smear scrapings (38% and 56%, respectively) as compared with the punch biopsies (44% and 83%, respectively). Microscopic concordance for punch biopsies and drop scrapings was present in 25 of 33 cases. Concordance was predicted only by the high/low parasitic index (PI: 3.1 ± 1.7 and 0.4 ± 0.5, respectively; P < 0.05). Herein, we optimized a novel rapid method for reliable diagnosis of CL based on drop scrapings with good agreement with the gold standard punch biopsy technique. PMID:25561563

In 2900 nm range, the effective scattering coefficient is much smaller than the absorption coefficient. An Er:YAG skin puncher is presented. Thermal action of a laser beam can be described as one of three types: hyperthermia, coagulation and volatilization, depending on the degree and the duration of tissue heating. We are interested in the volatilization process that means a loss of material. The various constituents of the tissue disappear in smoke at above 100 0C in a relatively short time of around one tenth of a second. At the edges of the volatilization zone there is a region of coagulation necrosis. In presented case of an Er:YAG laser operating in a free generation mode, the mechanical effects can result from explosive vaporization. When the exposure time of the laser is lower than the characteristic time of the thermal diffusion in the tissue, it produces a thermal containment with an accumulation of heat without diffusion and an explosive vaporization of the target. The Er:YAG laser device has the pulse length of about 160 microseconds and four emitted energy levels. This device is used to punch the skin for blood sampling for different kinds of analysis. The front panel of the device has four keys to select the desired energy according to the skin type.

    Full Text Available The paper reports the indentation of a semi-infinite, initially stressed elastic medium under the action of an axisymmetric rigid punch pressing the medium normally. Th~ problem has been considered within the framework of incremental deformation theory for neo-Hookean solids. Using the Hankel's transformation, the distributions of incremental stress and strain have been obtained. Indentations by a flat-ended c and a conical punch have been obtained as special cases and these effects have been studied numerically and presented in the form of curves. This problem has defence application as many launching pads and firing machines have some neo-Hookean solids as buffer which bear enormous impact or punch during the action of the machine.

  16. The effect of ion implantation on the lifetime of punches

    International Nuclear Information System (INIS)

    The electronics industry demands stamped parts with high performance. Therefore, punching tools like cutting punches with very high precision have to be used. In the case reported, the punches are mounted in a modular system and have to be resharpened or replaced after a certain number of strokes. To increase the lifetime of the punches made of Vasco Wear steel, implantations with carbon, nitrogen, boron and titanium, and co-implantation with titanium and carbon were performed at energies from 50 keV to 200 keV and 600 keV and 700 keV with different doses in the region of several times 1018 cm-2, measured perpendicular to the ion beam. A maximum increase in lifetime of a factor of 3.6 was reached. The surface roughness had a large influence on the increase lifetime and the improvement caused by specific ion species. The maximum improvement was obtained for the lowest surface roughness (Ra=0.04 μm). Therefore, when performing the implants, punches with low surface roughness should be used. The most successful ion species were boron and nitrogen for the lowest surface roughness used (Ra=0.04 μm), and after changing the polishing procedure (Ra=0.14 μm) titanium and nitrogen at medium energies (100-200 keV). High energy implantation (700 keV) resulted in an increase of a factor of 2.1 at lower doses (5.6x1017 cm-2), but is uneconomical owing to the low current density. In laboratory wear tests (ball on disk) no improvement by ion implantation could be found. These results prove that it is difficult to compare field tests and laboratory tests because of different testing conditions. (orig.)

  17. Small punch testing for fracture toughness measurement. Final report

    International Nuclear Information System (INIS)

    The fracture toughness of the material of an operating power plant structural component affects the flaw tolerance of the component. A lower toughness implies a lower flaw tolerance, and generally results in an increased concern for component integrity and higher operation and maintenance costs. Often, the material fracture toughness is unknown because it was never specified or measured, or because service conditions have resulted in its degradation to an unknown extent. Examples of in- service degradation include temper embrittlement of steam turbine rotor low alloy steels exposed to elevated temperatures and neutron irradiation embrittlement of nuclear reactor pressure vessel steels. Conventional test methods for measuring toughness require the removal of large material samples from the in-service component, which is generally impractical. However, the recent development of miniature sample removal systems and the small punch test technique (which utilizes non-standard, miniature specimens of 0.5 mm or 0.020 in. thickness) now provides a convenient, practical, and virtually nondestructive means of evaluating the material of an in-service component for toughness and related mechanical properties. The small punch test method follows an approach that is based on the continuum material toughness concept wherein the criterion for fracture is defined and measured via the continuum stress-strain deformation properties of the material. The procedure specifically involves computing the open-quotes localclose quotes strain energy density accumulated at the location and time of crack initiation in the small punch test specimen using large-strain finite element analysis. Since the procedure also includes estimation of the material uniaxial tensile stress-strain behavior from the small punch load-displacement curve, both the fracture toughness and the uniaxial tensile behavior are determined from a single small punch test

    Ion beam irradiation was adopted for surface treatment of the micro punch manufactured by precision machining. Ar plasma was used for the ion irradiation process, which was generated by the electron cyclotron resonance(ECR) equipment. The surface finish processes of micro punch were carried out at irradiation angles of 45°and 10°, respectively. The surface roughness and topography were measured to estimate the quality of surface finish. The results show that the ion irradiation is very effective to reduce the surface roughness, which can be improved more significantly at irradiation angle of 10°than at 45°. The technology of surface finish with ion beam irradiation is suitable for the surface treatment of micro die.

    The deployment of the martensitic alloy P91 in future nuclear plant components operating in the creep regime depends very much on the performance of joints, found occasionally susceptible to failure in fossil fuel fired plant A completely novel approach is proposed to assess the integrity of P91 weldments which relies on the determination of the creep properties of the different zones of the weldment on a micro-scale based on the Small Punch (SP) testing methodology. Results are presented from the Small Punch creep tests carried out exactly following a CEN Code of Practice for the various constituent zones of the weldment and the potential weaknesses are identified within the heat affected zone. In addition, the SP test is applied to determine the fracture properties of the weld compared to the parent metal, showing the expected shift related to the test method in the ductile brittle transition temperature and the inferior performance of the weld metal.

    2008-01-01

    We present modifications to conventional nanoindentation that realize variable temperature, flat punch indentation of ultrathin films. The technique provides generation of large strain, thin film extrusion of precise geometries that idealize the essential flows of nanoimprint lithography, and approximate constant area squeeze flow rheometry performed on thin, macroscopic soft matter samples. Punch radii as small as 185 nm have been realized in ten-to-one confinement ratio testing of 36 nm thick polymer films controllably squeezed in the melt state to a gap width of a few nanometers. Self-consistent, compressive stress versus strain measurements of a wide variety of mechanical testing conditions are provided by using a single die-sample system with temperatures ranging from 20 to 125 degrees C and loading rates spanning two decades. Low roughness, well aligned flat punch dies with large contact areas provide precise detection of soft surfaces with standard nanoindenter stiffness sensitivity. Independent heating and thermometry with heaters and thermocouples attached to the die and sample allow introduction of a novel directional heat flux measurement method to ensure isothermal contact conditions. This is a crucial requirement for interpreting the mechanical response in temperature sensitive soft matter systems. Instrumented imprint is a new nanomechanics material testing platform that enables measurements of polymer and soft matter properties during large strains in confined, thin film geometries and extends materials testing capabilities of nanoindentation into low modulus, low strength glassy, and viscoelastic materials.

  1. Dynamic Virtual Credit Card Numbers

    Molloy, Ian; Li, Jiangtao; Li, Ninghui

    Theft of stored credit card information is an increasing threat to e-commerce. We propose a dynamic virtual credit card number scheme that reduces the damage caused by stolen credit card numbers. A user can use an existing credit card account to generate multiple virtual credit card numbers that are either usable for a single transaction or are tied with a particular merchant. We call the scheme dynamic because the virtual credit card numbers can be generated without online contact with the credit card issuers. These numbers can be processed without changing any of the infrastructure currently in place; the only changes will be at the end points, namely, the card users and the card issuers. We analyze the security requirements for dynamic virtual credit card numbers, discuss the design space, propose a scheme using HMAC, and prove its security under the assumption the underlying function is a PRF.

  5. A New Sheet Metal Forming System Based on Incremental Punching

    Science.gov (United States)

    Luo, Yuanxin

    Stamping is one of the most commonly used manufacturing processes. Everyday, millions of parts are formed by this process. The conventional stamping is to form a part in one or several operations with a press machine and a set/sets of dies. It is very efficient but is not cost effective for small batch production parts and prototypes as the dies are expensive and time consuming to make. Recently, with the increasing demands for low-volume and customer-made products, a die-less forming method, Incremental Sheet Metal Forming (ISMF), has become one of the leading R&D topics in the industry. ISMF uses a small generic tool to apply a sequence of operations along the given path to deform the sheet incrementally. These small deformations accumulate to form the final shape of the part. As a result, different parts can be made by the same setup. Despite of some 30 years of research and development, however, ISMF technology is still premature for industrial applications due to the following reasons: The accuracy of the part is limited; the surface roughness is poor; and the productivity is low. This motivates the presented research. In this research, a new incremental forming system based on incremental punching is designed and built. The system consists of a 3-axes CNC platform, a high speed hydraulic cylinder with a hemispherical forming tool, and a PC-based CNC control system. The hydraulic system provides the forming force to deform the sheet metal with constant stokes, while the CNC system positions the part. When forming a part, the forming tool punches the sheet metal along the given contour of the part punch by punch; when one layer of the part is completed, the forming tool moves down to the next layer; and the process is finished till all layers are completed. The CNC control system works with standard NC code, and hence, is easy to use. In order to ensure the desirable performance of the machine, dynamic analysis of the machine is necessary. The analysis is

  6. Credit card interchange fees

    OpenAIRE

    Rochet, Jean-Charles; Wright, Julian

    2009-01-01

    We build a model of credit card pricing that explicitly takes into account credit functionality. We show that a monopoly card network always selects an interchange fee that exceeds the level that maximizes consumer surplus. If regulators only care about consumer surplus, a conservative regulatory approach is to cap interchange fees based on retailers’ net avoided costs from not having to provide credit themselves. In the model, this always raises consumer surplus compared to the unregulated o...

  8. Small Punch Tests applied to the nuclear industry

    International Nuclear Information System (INIS)

    The interest on miniaturized specimen techniques for the characterization of the mechanical behavior of materials was strongly motivated in the early eighties by the different programs associated with the development of fusion reactor technology. The importance of such developments is obvious in the case of the nuclear industry where the limited space available, the presence of fluence gradients in large specimens, the concern about gamma heating and dose to personnel in post-irradiation testing have all been motivations for reducing specimen size. Testing of miniature specimen includes a wide spectrum of techniques such as tensile, instrumented micro-hardness, small punch, bend, fracture, impact and fatigue. Small Punch Testing (SPT) techniques use a spherical penetrator which deforms to failure a miniature disc shaped flat specimen (typically, 3-10 mm in diameter and 0.25-0.50 mm in thickness) supported on its outer rim. Analysis of load-displacement data recorded along the test is performed for the determination of the property of interest. The present work focuses on the characterization of the elastoplastic response of pure Al, ADN 420 structural steel and AISI 304L using SPT and its correlation with the associated standard uniaxial testing behavior. In addition, the sensitivity of the technique to the specific material under study and to different experimental parameters, i.e. specimen diameter and thickness, clearance or clamping force and friction between disc and dies have been assessed both experimentally and by performing simulations using the finite element method (author)

    Among the noises of the punch press, blanking noise and engaging noise of the clutch should be paid most attention to. The latter is generated by the engagement impacts of the rotating key on the spline bush. In order to absorb the pressing energy and reduce the noise radiated, polyurethane cushions were added to the spline bush keyways and the clutch running noise reduction has reached 10.7 dB(A). Considering such factors as the running characteristics of the punch press clutch, the demand for cushioning performance and the demand of the clutch temperature field for damping materials, the temperature field of the rigid clutch spline bush was simulated to find out whether the temperature of polyurethane go beyond its critical application temperature, using the finite element method. According to the characteristic that the deforming memory alloy can restore the remembered shape with the temperature rising, the actual temperature of the spline bush was measured. Consequently, the theoretical temperature turned out to be close to the measured temperature.

    1996-05-01

    The Time Card Entry System was developed to interface with the DOE Headquarters Electronic Time and Attendance (ETA) system. It features pop-up window pick lists for Work Breakdown Structure Numbers and Hour Codes and has extensive processing that ensures that time and attendance reported by the employee fulfills US Government/OMB requirements before Timekeepers process the data at the end of the two week payroll cycle using ETA. Tours of Duty (e.g. ten hour day, four day week with Friday through Sunday off), established in the ETA system, are imported into the Time Card Entry System by the Timekeepers. An individual`s Tour of Duty establishes the basis for validation of time of day and number of hours worked per day. At the end of the two week cycle, data is exported by the Timekeepers from the Time Card Entry System into ETA data files.

  18. Simultaneous DNA and RNA isolation from brain punches for epigenetics

    Directory of Open Access Journals (Sweden)

    Spengler Dietmar

    2011-08-01

    Full Text Available Abstract Background Epigenetic modifications such as DNA methylation play an important role for gene expression and are regulated by developmental and environmental signals. DNA methylation typically occurs in a highly tissue- and cell-specific manner. This raises a severe challenge when studying discrete, small regions of the brain where cellular heterogeneity is high and tissue quantity limited. Because gene expression and methylation are often tightly linked it appears of interest to compare both parameters in the same sample. Findings We present a refined method for the simultaneous extraction of DNA for bisulfite sequencing and RNA for expression analysis from small mouse brain tissue punches. This method can also be easily adapted for other small tissues or cell populations. Conclusions The method described herein results in DNA and RNA of a quantity and quality permitting highly reliable bisulfite analysis and quantitative RT-PCR measurements, respectively.

  19. Hydration swelling characteristics of needle-punched geosynthetic clay liners

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    A series of confined swell tests were conducted on a needle-punched geosynthetic clay liner (GCL)with tap water as the hydration medium. The effects of the static confining stress on the swelling characteristics of GCLs and the hydration time under different confining stresses were explored. Increasing the static confining stress led to: shorter hydration time; smaller final GCL height; less final GCL bulk void ratio; smaller final bentonite moisture content. The confined swell pressure determined for the tested GCL was 82.2 kPa, and the relationships between confining stress, final bulk void ratio (or final GCL height, final bentonite moisture content) were attained through the analyses of the confined swell test results in this study.

  20. Qualification of P91 welds through Small Punch creep testing

    International Nuclear Information System (INIS)

    Full text: As a result of its high temperature creep strength, the martensitic alloy P91 is a strong candidate for application as a pressure vessel and heat exchanger material of construction in Next Generation nuclear plant. This candidature is supported by lengthy and successful operation in other high temperature plant in particular in fossil fuel fired plant. The only potential area of concern which will have to be taken into account for the nuclear application concerns the behaviour of construction weldments. Any risk of Type IV cracking has to be avoided and hence a thorough knowledge concerning the integrity of the weld has to be demonstrated. This can be achieved on the macro scale through cross weld creep testing although the results of such tests are difficult to interpret and are not included in design codes. A novel approach is proposed which relies on the determination of the creep properties of the different zones of the weldment on a micro-scale based on the Small Punch Testing methodology. Although results from such tests are similarly debarred from design codes at present, the potential of the method should be evaluated through testing and analysis as it has a second prospective role in plant operation lifetime assessment once the plant is in operation. The test methodology has recently been incorporated into a CEN Code of Practice in order to improve the acceptability of the results. In this paper, results are presented from the Small Punch creep tests carried out exactly following the Code of Practice for the various constituent zones of the weldment and the potential weaknesses are identified within the heat affected zone.

  2. Giant magnetism in punched zigzag-edged triangular-shaped graphene nanodisks

    We observe, for the first time, a very large magnetism in the nano-sized (7–27 Å) punched graphene nanodisks (PGNDs) i.e., zigzag-edged triangular PGNDs (ZET-PGNDs). A first-principles method has been employed to investigate their electronic and magnetic properties. Similar to a regular or unpunched ZET-GND where the spin value scales with the linear dimension of the ZET-GND arising from the topological frustration of the π bonds and the induced spin distributions in graphene structures, the magnetic moment in a PGND increases with its size very rapidly depending on the type of punching. Two types of the punched nanodisks have been discussed. In one type of PGND, the magnetic moment of the punched out smaller GND is added to the magnetic moment of the host GND and the resultant net magnetism is, thus, equal to the sum of the magnetic moments of the host GND and that of the punched out smaller GND. In the other type of the PGND, the magnetic moment of the punched out smaller GND is subtracted from the magnetic moment of the host GND and the net value of the magnetic moment is the difference of the magnetic moments of the host GND and that of the punched out smaller GND. One may, thus, enhance the magnetism of a GND by making an appropriate choice of the punching. It may have large magnetic moments in the passivated ZET-PGNDs beyond the nanoscale at room temperature. These punched graphene fragments may be employed for the preparation of several kinds of the electronic and spintronic devices possessing exotic features.

  4. Influence of punching shear reinforcement on the flexural response of flat slabs

    Physical punching shear models such as the Critical Shear Crack Theory (CSCT), which is the basis of Model Code 2010 (MC 2010), describe generally the punching strength as a function of the slab deformation. Thus, the prediction of an accurate load-deformation curve is essential for the prediction of the punching strength as well as the deformation capacity of flat slabs. In the vicinity of columns, the flexural response of flat slabs depends not only on the flexural moments but also on the c...

    This investigation was a continuing study of peripheral (punching) shear strength of precracked, biaxially tensioned, orthogonally reinforced concrete slabs. This research was motivated by the need to determie the strength of a reinforced concrete containment vessel wall when subjected to combined internal pressure and punching shear loads normal to the wall. The study served to determine the effect of three major variables (shear span, size of loaded area, and reinforcing steel ratio) on punching shear strength of slabs that were precracked in biaxial tension and then held at one of the two tension levels (0 or 0.8f/sub y/) during shear load application

    2016-07-01

    During the 1640s, the Irish Franciscan theologian John Punch taught his theology students in Rome that war against Protestants was made just by their religion alone. Jesuits like Luis de Molina identified the holy war tradition in which Punch stood as a Scotist one, and insisted that the Scotists had confused the natural and supernatural spheres. Among Irishmen, Punch was unusual. The main Irish Catholic revolutionary tradition employed Jesuit and Thomist theory. They argued that the Stuarts had lost the right to rule Ireland for natural reasons, not supernatural ones; because the Stuarts were tyrants, not because they were Protestants. PMID:27477343

  15. Performance Assessment of Hard Rock TBM and Rock Boreability Using Punch Penetration Test

    Science.gov (United States)

    Jeong, Ho-Young; Cho, Jung-Woo; Jeon, Seokwon; Rostami, Jamal

    2016-04-01

    Rock indentation tests are often called punch penetration tests and are known to be related to penetration rates of drilling equipment and hard rock tunnel boring machines (TBMs). Various indices determined from analysis of the force-penetration plot generated from indentation tests have been used to represent the drillability, boreability, and brittleness of rocks. However, no standard for the punch penetration test procedure or method for calculating the related indices has been suggested or adopted in the rock mechanics community. This paper introduces new indices based on the punch test to predict the performance of hard rock TBMs. A series of punch tests was performed on rock specimens representing six rock formations in Korea with different dimensions, i.e., the core specimens had different lengths and diameters. Of the indices obtained from the punch tests, the peak load index and mean load index showed good correlations with the cutting forces measured in full-scale linear cutting machine tests on the same rock types. The indices also showed good linear correlations with the ratio of uniaxial strength to Brazilian tensile strength, which indicates the brittleness of rock. The scale effect of using core specimens was investigated, and a preferred dimension for the punch test specimens is proposed. This paper also discusses the results of the punch test and full-scale rock cutting tests using LCM. The results of this study confirm that the proposed indices from the punch tests can be used to provide a reliable prediction of the cutting forces that act on a disc cutter. The estimated cutting forces can then be used for optimization of cutter-head design and performance prediction of hard rock TBMs.

    This paper proposes a mechanism for anonymous credit card systems, in which each credit card holder can conceal individual transactions from the credit card company, while enabling the credit card company to calculate the total expenditures of transactions of individual card holders during specified periods, and to identify card holders who executed dishonest transactions. Based on three existing mechanisms, i.e. anonymous authentication, blind signature and secure statistical data gathering, together with implicit transaction links proposed here, the proposed mechanism enables development of anonymous credit card systems without assuming any absolutely trustworthy entity like tamper resistant devices or organizations faithful both to the credit card company and card holders.

    Full Text Available Autologous split thickness miniature punch skin grafting is one of the surgical modes of treatment of stable vitiligo. Out of 87 different sites, of stable vitiligo, occurring in 62 cases, (32 focal, 22 segmental and 8 generalised 75 sites showed total repigmentation with excellent cosmetic colour match. Out of the 62 cases, 46 cases who were treated postsurgically with PUVA therapy repigmented within 2 ½ to 3 months, 10 cases, who received no treatment postsurgically repigmented by 3 ½ to 6 months. In addition 6 cases in whom no treatment was given postsurgically had to be given PUVA therapy 3 months after surgery as there was poor repigmentation. The complications seen were graft rejection due to improper immobilization in 6 cases, graft rejection due to secondary infection in 1, contact allergic dermatitis to framycetin in 3, and reactivation of vitiligo in 2. Side effects seen were cobblestoning in 32, sinking pits in 12, variegated appearance in 4, and superficial scarring at donor site in all 62 cases.

    2016-10-01

    In this study, a fast and simple blood sampling and sample pre-treatment method based on the use of the dried blood spot (DBS) cards and ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) for the quantification of olive oil phenolic metabolites in human blood was developed and validated. After validation, the method was applied to determine hydroxytyrosol metabolites in human blood samples after the acute intake of an olive oil phenolic extract. Using the FTA DMPK-A DBS card under optimum conditions, with 20µL as the blood solution volume, 100µL of methanol/Milli-Q water (50/50, v/v) as the extraction solvent and 7 disks punched out from the card, the main hydroxytyrosol metabolites (hydroxytyrosol-3-O-sulphate and hydroxytyrosol acetate sulphate) were identified and quantified. The developed methodology allowed detecting and quantifying the generated metabolites at low μM levels. The proposed method is a significant improvement over existing methods to determine phenolic metabolites circulating in blood and plasma samples, thus making blood sampling possible with the volunteer pricking their own finger, and the subsequent storage of the blood in the DBS cards prior to chromatographic analysis.

  2. Authentication techniques for smart cards

    International Nuclear Information System (INIS)

    Smart card systems are most cost efficient when implemented as a distributed system, which is a system without central host interaction or a local database of card numbers for verifying transaction approval. A distributed system, as such, presents special card and user authentication problems. Fortunately, smart cards offer processing capabilities that provide solutions to authentication problems, provided the system is designed with proper data integrity measures. Smart card systems maintain data integrity through a security design that controls data sources and limits data changes. A good security design is usually a result of a system analysis that provides a thorough understanding of the application needs. Once designers understand the application, they may specify authentication techniques that mitigate the risk of system compromise or failure. Current authentication techniques include cryptography, passwords, challenge/response protocols, and biometrics. The security design includes these techniques to help prevent counterfeit cards, unauthorized use, or information compromise. This paper discusses card authentication and user identity techniques that enhance security for microprocessor card systems. It also describes the analysis process used for determining proper authentication techniques for a system

    2000-01-01

    Java card is a new system for programming smart cards, which is based on the Java language and Virtual Machine. Java card programs (applets)run in Java Card Runtime Environment (JCRE) including the Java Card Virtual Machine (JCVM), the framework, the associated native methods and the API (Application Programming Interface). JCVM is implemented as two separate pieces:off-card VM (Virtual Machine) and on-card VM. The stack model and heap memory structure used by on-card VM and exception handling are introduced. Because there are limited resources within smart card environment, and garbage collection is not supported in JCVM, the preferred way to exception handling does not directly involve the use of throw, although the throw keyword is supported. Security is the most important feature of smart card. The Java card applet security feature is also discussed.

  5. Experimental and Numerical Simulation Research on Micro-Gears Fabrication by Laser Shock Punching Process

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available The aim of this paper is to fabricate micro-gears via laser shock punching with Spitlight 2000 Nd-YAG Laser, and to discuss effects of process parameters namely laser energy, soft punch properties and blank-holder on the quality of micro-gears deeply. Results show that dimensional accuracy is the best shocked at 1690 mJ. Tensile fracture instead of shear fracture is the main fracture mode under low laser energy. The soft punch might cause damage to punching quality when too high energy is employed. Appropriate thickness and hardness of soft punch is necessary. Silica gel with 200 µm in thickness is beneficial to not only homogenize energy but also propagate the shock wave. Polyurethane films need more energy than silica gel with the same thickness. In addition, blank-holders with different weight levels are used. A heavier blank-holder is more beneficial to improve the cutting quality. Furthermore, the simulation is conducted to reveal typical stages and the different deformation behavior under high and low pulse energy. The simulation results show that the fracture mode changes under lower energy.

    2005-01-01

    This paper present an experimental study on the RC slab-column connections with nonrectangular columns, namely cross-shaped column, T-shaped column and L-shaped column. The punching shear deformation and strength characteristics of slab-column connections with nonrectangular columns under punching shear load are investigated. Nine specimens with the three kinds of nonrectangular columns and two reference specimens with square columns are tested. The tested ultimate loads, deformations, and failure modes of specimens are presented and discussed. Test results reveal that the punching shear strength and ductility of the connections with nonrectangular columns are higher than those of the corresponding connections with square columns, and also prove that the application of nonrectangular columns to flat-plate structure was feasible. Based on the test results, one method of calculating punching shear strength of connections with nonrectangular columns is proposed, which conforms with the current design practice of China. The test results on the punching shear strength are compared with the predictions of the formulas proposed by codes of several different countrie; and the predictions given by ACI code and China code are found to be conservative as the reinforcement ratio is increased.

  7. Shear punch tests performed using a new low compliance test fixture

    International Nuclear Information System (INIS)

    Based on a recent finite element analysis (FEA) study performed on the shear punch test technique, it was suggested that compliance in a test frame and fixturing which is quite acceptable for uniaxial tensile tests, is much too large for shear punch tests. The FEA study suggested that this relatively large compliance was masking both the true yield point and the shape of the load versus displacement trace obtained in shear punch tests. The knowledge gained from the FEA study was used to design a new shear punch test fixture which more directly measures punch tip displacement. The design of this fixture, the traces obtained from this fixture, and the correlation between uniaxial yield stress and shear yield stress obtained using this fixture are presented here. In general, traces obtained from the new fixture contain much less compliance resulting in a trace shape which is more similar in appearance to a corresponding uniaxial tensile trace. Due to the more direct measurement of displacement, it was possible to measure yield stress at an offset shear strain in a manner analogous to yield stress measurement in a uniaxial tensile test. The correlation between shear yield and uniaxial yield was altered by this new yield measurement technique, but the new correlation was not as greatly improved as was suggested would occur from the FEA study

  8. Validation of the shear punch-tensile correlation technique using irradiated materials

    International Nuclear Information System (INIS)

    It was recently demonstrated that tensile data could be successfully related to shear punch data obtained on transmission electron microscopy (TEM) discs for a variety of irradiated alloys exhibiting yield strengths that ranged from 100 to 800 MPa. This implies that the shear punch test might be a viable alternative for obtaining tensile properties using a TEM disk, which is much smaller than even the smallest miniature tensile specimens, especially when irradiated specimens are not available or when they are too radioactive to handle easily. The majority of the earlier tensile-shear punch correlation work was done using a wide variety of unirradiated materials. The current work extends this correlation effort to irradiated materials and demonstrates that the same relationships that related shear punch tests remain valid for irradiated materials. Shear punch tests were performed on two sets of specimens. In the first group, three simple alloys from the 59Ni isotopic doping series in the solution annealed and cold worked conditions were irradiated at temperatures ranging from 365 to 495 C in the Fast Flux Test Facility. The corresponding tensile data already existed for tensile specimens fabricated from the same raw materials and irradiated side-by-side with the disks. In the second group, three variants of 316 stainless steel were irradiated in FFTF at 5 temperatures between 400 and 730 C to doses ranging from 12.5 to 88 dpa. The specimens were in the form of both TEM and miniature tensile specimens and were irradiated side-by-side

  10. Hydrodynamics on graphic cards

    International Nuclear Information System (INIS)

    In the field of high-energetic nucleus-nucleus collisions at RHIC and LHC ideal and dissipative relativistic hydrodynamics is used to calculate the evolution of hot and dense QCD matter. A large body of current numerical tools employs relativistic hydrodynamics in various facets. The acceleration of relativistic hydrodynamics using graphic cards (GPUs) is therefore of highest relevance to this fields. The results reported here are based on the Sharp And Smooth Transport Algorithm SHASTA, which is employed in many hydrodynamical models and hybrid simulation packages, e.g. the Ultrarelativistic Quantum Molecular Dynamics model (UrQMD). We have redesigned the SHASTA using the OpenCL computing framework to work on accelerators like graphic processing units (GPUs) as well as on multi-core processors. With the redesign of the algorithm the hydrodynamic calculations have been accelerated by a factor 160 allowing for event-by-event calculations and better statistics in hybrid calculations.

  16. Improved small punch testing and parameter identification of ductile to brittle materials

    International Nuclear Information System (INIS)

    Minimal invasive material testing is of special interest, when only small amounts of material are available or the material degradation of structural components in service has to be evaluated. The disc-shaped specimens used in the small punch test are small enough for local material sampling but representative for characterizing the macroscopic material behaviour. A small punch test device was developed which enables the testing of materials in the whole range from ductile to brittle failure and from ambient temperature down to −190 °C in a unique experimental set-up. The specimens are not clamped as usually in the small punch test. This is crucial for brittle fracture behaviour with little or without plastic deformation. The measured load displacement curve of the punch represents the non-linear response of the material due to elastic–plastic deformation. It contains relevant information about true material parameters, which can be made accessible by solving the inverse problem. Thus, plastic yield curves and Weibull parameters were identified by combining finite element simulations with non-linear optimization techniques. Examples for measured load displacement curves and related results of parameter identification are shown for a pressure vessel steel and a laser welded joint. The results obtained from the small punch test are verified by data from standard specimen tests. - Highlights: • Improved small punch test suited for the whole range of ductile to brittle materials. • Minimal invasive determination of true material parameters by means of numerical simulations. • Temperature dependent yield curve parameters were identified using a response surface approach. • Estimation of Weibull parameters of cleavage fracture for steels at low temperatures

  17. Determination of the toughness of in-service steam turbine disks using small punch testing

    Science.gov (United States)

    Foulds, J.; Viswanathan, R.

    2001-10-01

    Knowledge of the material toughness is crucial in assessing the integrity of heavy section steel components. Conventional tests to determine the toughness involve extraction of large blocks of materials and therefore are not practical on in-service components. On the other hand, conservative assumptions regarding toughness without regard to actual data can lead to expensive and premature replacement of the components. Previous EPRI studies have demonstrated the use of a relatively nondestructive technique termed the "small punch test" to estimate the fracture appearance transition temperature (FATT) and fracture toughness ( K Ic ) of high-temperature turbine rotor steels and nuclear reactor pressure vessel steels. This paper summarizes the results of research into the feasibility of extending the small punch test to characterize the toughness of the 3 to 3.5% NiCrMoV (3-3.5NiCrMoV) low alloy steel used for fossil and nuclear power plant low-pressure (LP) steam turbine disks. Results of the present study show that the small punch transition temperature, T sp , is linearly correlated with FATT, so that measurement of T sp permits estimation of the standard Charpy FATT through empirical use of the correlation. The statistical confidence prediction uncertainty bands for the correlation were found to be narrow enough to make the small punch- based FATT estimation practical for this alloy. Additionally, independent K Ic measurements made by PowerGen, UK, on some of the same test materials were in excellent agreement with measurements made here, indicating that the small punch K Ic measurement can be reproducible across laboratories. Limited testing for fracture initiation toughness showed, as has been demonstrated for other materials, that the small punch test-based initiation fracture toughness ( K Ic ) determination was within ±25% of the ASTM standard measurement of K Ic , suggesting that the test method can be used for direct determination of fracture initiation

    The small punch test technique (SPT) was used to evaluate the mechanical properties of various materials and the basic method to test material tensile mechanics performance from an inverse finite element (FE) arithmetic with SPT was put forward. The research shows that specific tensile mechanical behavior and strain-stress distribution of each district of weld seam can be accurately determined by small punch test. Therefore, mechanical behavior of the inhomogeneous joint can be predicted by a numerical model. The simulation comes to good agreement with experimental data.

    Consider three players Alice, Bob and Cath who hold a, b and c cards, respectively, from a deck of d=a+b+c cards. The cards are all different and players only know their own cards. Suppose Alice and Bob wish to communicate their cards to each other without Cath learning whether Alice or Bob holds a specific card. Considering the cards as consecutive natural numbers 0,1,..., we investigate general conditions for when Alice or Bob can safely announce the sum of the cards they hold modulo an appropriately chosen integer. We demonstrate that this holds whenever a,b>2 and c=1. Because Cath holds a single card, this also implies that Alice and Bob will learn the card deal from the other player's announcement.

    In this paper, we propose a data stream management system embedded to a smart card for handling and storing user specific summaries of streaming data coming from medical sensor measurements and/or other medical measurements. The data stream management system that we propose for a health card can handle the stream data rates of commonly known medical devices and sensors. It incorporates a type of context awareness feature that acts according to user specific information. The proposed system is cheap and provides security for private data by enhancing the capabilities of smart health cards. The stream data management system is tested on a real smart card using both synthetic and real data. PMID:22127523

    Small punch (SP) test techniques are typically used to study the mechanical properties of materials or components from miniature size specimens. This kind of test was originally developed to assess ductility loss in steel caused by irradiation or thermal treatment, particularly when the amount of metal was limited, but it soon proved to be a powerful method to estimate several properties.

  3. Influence of Punch Velocity on Gas Hydrogen Embrittlement Behaviors in SA372 Steel

    International Nuclear Information System (INIS)

    When using hydrogen gas as an ecofriendly energy sources, it is necessary to conduct a safety assessment and ensure the reliability of the hydrogen pressure vessel against hydrogen embrittlement expected in the steel materials. In this study, by applying the in-situ SP test method, the gas hydrogen embrittlement behaviors in SA372 steel, which is commonly used as a pressurized hydrogen gas storage container, were evaluated. To investigate the hydrogen embrittlement behavior, SP tests at different punch velocities were conducted for specimens with differently fabricated surfaces at atmospheric pressure and under high-pressure hydrogen gas conditions. As a result, the SA372 steel showed significant hydrogen embrittlement under pressurized hydrogen gas conditions. The effect of punch velocity on the hydrogen embrittlement appeared clearly; the lower punch velocity case indicated significant hydrogen embrittlement resulting in lower SP energy. The fractographic morphologies observed after SP test also revealed the hydrogen embrittlement behavior corresponding to the punch velocity adopted. Under this pressurized gas hydrogen test condition, the influence of specimen surface condition on the extent of hydrogen embrittlement could not be determined clearly

    Seven silver punch-marked coins were analysed using external particle induced X-ray emission technique. The main group of elements like Ag, Cu, Au, Pb and Fe were estimated along with a number of trace/minor elements such as K, Ca, Ti, V, Cr, Mn, Co, Ni and Rb in the analysed silver coins. Gold was found in all the coins and varied between 0.7% and 6.2% indicating the better economic condition of that civilisation. - Highlights: > The silver punch-marked coins, in the current study, were in use in India between 6th century BC to 6th century AD and have been analysed by in-air PIXE. > These sets of coins have immense archaeological importance because of their very rare availability. > These coins are distinguished from other coins because of the presence of gold as major element. > While the British period coins were fabricated using modern technologies, the punch-marked coins were shaped manually with developed metal technology. > The analysis of punch-marked coins using external PIXE beam has been done for the first time, which is unique of its kind.

  7. Small punch creep test: A promising methodology for high temperature plant components life evaluation

    CISE and ENEL are involved for years in a miniaturization creep methodology project to obtain similar non-destructive test with the same standard creep test reliability. The goal can be reached with `Small punch creep test` that collect all the requested characteristics; quasi nondestructive disk specimens extracted both on external or internal side of components, than accurately machined and tested on little and cheap apparatus. CISE has developed complete creep small punch procedure that involved peculiar test facility and correlation`s law comparable with the more diffused isostress methodology for residual life evaluation on ex-serviced high temperature plant components. The aim of this work is to obtain a simple and immediately applicable relationship useful for plant maintenance managing. More added work is need to validate the Small Punch methodology and for relationship calibration on most diffusion high temperature structural materials. First obtained results on a comparative work on ASTM A355 P12 ex-serviced pipe material are presented joint with a description of the Small Punch apparatus realized in CISE. (orig.) 6 refs.

  8. Evaluation of ductility of zircaloy-2 materials using a small ellipsoidal-shaped punch

    International Nuclear Information System (INIS)

    Seam-welded Zircaloy-2 calandria tubes are used in the fuel channel of CANDU reactors, to isolate the hot pressure tube from the cool heavy-water moderator. The mechanical properties of irradiated welds are required to assess whether they will be satisfactory to the end-of-life of the reactor. It is impractical to irradiate short sections of calandria tube for burst testing. Therefore, we have developed a small ellipsoidal-shaped punch to evaluate the mechanical properties of anisotropic Zircaloy-2 material having various microstructures such as those present in a welded calandria tube. Small punch tests were performed on four different types of calandria tubes, two welded and two seamless, and the results show that the mechanical anisotropy of the tubes could be differentiated. The fracture produced in unirradiated small specimens showed a straight-line crack, similar to a straight-line rupture on a tube during burst testing. A re-constitution of the properties from small specimens was used for correlation with the burst properties of the tubes. A consistent correlation was obtained for the punch load and displacement with the burst strength and ductility of the tubes. Based on this correlation, mechanical properties of irradiated welds using the small ellipsoidal punch method are being evaluated. (author)

    Science.gov (United States)

    Androulaki, Elli; Bellovin, Steven

    Credit cards have many important benefits; however, these same benefits often carry with them many privacy concerns. In particular, the need for users to be able to monitor their own transactions, as well as bank’s need to justify its payment requests from cardholders, entitle the latter to maintain a detailed log of all transactions its credit card customers were involved in. A bank can thus build a profile of each cardholder even without the latter’s consent. In this paper, we present a practical and accountable anonymous credit system based on ecash, with a privacy preserving mechanism for error correction and expense-reporting.

    Motivation - Under the new upgrade of the CMS detector the working temperature of the trackers had been reduced to -27 Celsius degrees. Though the thermal sensors themselves (Murata and Fenwal thermistors) are effective at these temperatures, the max1542 PLC (programmable logic controller) cards, interpreting the resistance of the thermal sensors into DC counts usable by the DCS (detector control system), are not designed for these temperatures in which the counts exceed their saturation and therefor had to be replaced. In my project I was in charge of handling the emplacement and calibration of the new PLC cards to the TOB (tracker outer barrel) control system.

    The process of soft-punch hydro-forming was use.cl to form some workpieces. However, it has not been completely understood until now. In this paper, based on some primary experiments, in which cups have been tried under different working conditions with the soft-punch hydro-forming process, systematical know-how about why the LDR of a metal sheet is different, how working conditions influence qualities of a work-piece,and how the deformation takes place has been achieved when simulations are employed. All these results claim that the cup depth heavily weighs on the cup wall thinning rate, and a satisfied complex part can be achieved when the contacting time between the sheet and the female die is under our control well by a movable slider,which is fixed as the bottom of the female die.

  18. Evaluation of thermal aging embrittlement in CF8 duplex stainless steel by small punch test

    International Nuclear Information System (INIS)

    Small punch test was performed on CF8 duplex stainless steel aged at 370 and 400 deg. C for up to 5000 h to characterize thermal aging embrittlement. At room temperature, the small punch (SP) load-displacement curve was similar in shape to those of ferritic steels and exhibited a good reproducibility in spite of ferrite-austenite structure. As the test temperature was lowered to a certain temperature depending on the degree of aging, the SP load showed a sudden drop followed by curve serration before the SP specimen fractured, resulting from the cracking of ferrite phase. While the aging heat treatment led to a slight increase of the yield strength, the transition appearing in the SP energy versus temperature curves shifted to higher temperature due to the hardening of ferrite phase. Additionally, phase boundary separation was an important factor in the degradation of the steel aged at 400 deg. C

    Science.gov (United States)

    Schyma, C; Schyma, P

    1997-01-01

    Manurhin developed a "non lethal" weapon, the MR 35 Punch, which fires 21 g weighing rubber balls of 35 mm caliber. The black powder cartridges which were used as propellant cause important variations of the projectile's velocity from 120 to 140 m/s. The resulting energies were about 150 to 200 J. The wounding potential was examined by shots on different materials and gelatin. Shots from 2 to 5 m distance caused penetrations of 3 to 8 cm in 10 percent gelatin. Covering the gelatin with skin or thick textiles did not significantly change the penetration. Skin and textiles were penetrated in all experiments. Pieces of flat bone which were embedded in gelatin were fractured by the shots, in part fracture elements were dislocated. The discussion of the wound ballistic results contradict the "non lethal" character of the MR 35 Punch. PMID:9446526

    Small punch testing is now a widely recognised approach for obtaining useful mechanical property information of critical structural components, particularly in the nuclear industry. However, to date the utilisation of this method has been limited to isotropic materials such as aluminium alloys and steels. This paper will look to utilise the small punch (SP) test to assess the creep response of 〈001〉-orientated CMSX-4 at temperatures above 950 °C. An orthogonal rafting regime of the γ′ structure is observed in the post-test microstructure due to the biaxial tension state typically produced in a SP test. Interpretation of the SP results to correlate with uniaxial creep data is carried out by employing the ksp approach in order to provide a platform for future material assessment

    The effective shear yield and maximum strengths of a set of neutron-irradiated, isotopically tailored austentic alloys were evaluated using the shear punch test. The dependence on composition and neutron dose showed the same trends as were observed in the corresponding miniature tensile specimen study conducted earlier. A single tensile-shear punch correlation was developed for the three alloys in which the maximum shear stress or Tresca criterion was successfully applied to predict the slope. The correlation will predict the tensile yield strength of the three different austenitic alloys tested to within {+-}53 MPa. The accuracy of the correlation improves with increasing material strength, to within {+-} MPa for predicting tensile yield strengths in the range of 400-800 MPa.

    Full Text Available This paper presents results of punching tests carried out in four reinforced concrete flat slabs, one of them without shear reinforcement and others strengthened with CFRP dowels. Slabs were 1000 mm square meters and 60 mm thick and were subjected to mid span loadings until failure. The strengthening arrangements were radial and cruciform, varying the number of layers of CFRP dowels. The results presented include vertical displacements, strain on steel and concrete, ultimate loads and failure mode, as well as estimation of resistance based on the Brazilian standards. It was observed significant improvement on punching resistance of the strengthened slabs when compared to the reference slab, highlighting the good performance for the strengthening system evaluated.

    The traditional approach of codes of practice for estimating the punching strength of shear-reinforced flat slabs is based on the assumption that concrete carries a fraction of the applied load at ultimate while the rest of the load is carried by the shear reinforcement. Concrete contribution is usually estimated as a fraction of the punching strength of members without shear reinforcement. The ratio between the concrete contribution for members with and without shear reinforcement is usually...

    The paper presents studies and researches results of the implementation of Teamcenter (TC) integrated management of a product lifecycle, in a virtual enterprise. The results are able to be implemented also in a real enterprise. The product was considered a successive punching and cutting tool, designed to materialize a metal sheet part. The paper defines the technical documentation flow (flow of information) in the process of constructive computer aided design of the tool. After the design phase is completed a list of parts is generated containing standard or manufactured components (BOM, Bill of Materials). The BOM may be exported to MS Excel (.xls) format and can be transferred to other departments of the company in order to supply the necessary materials and resources to achieve the final product. This paper describes the procedure to modify or change certain dimensions of sheet metal part obtained by punching. After 3D and 2D design, the digital prototype of punching tool moves to following lifecycle phase of the manufacturing process. For each operation of the technological process the corresponding phases are described in detail. Teamcenter enables to describe manufacturing company structure, underlying workstations that carry out various operations of manufacturing process. The paper revealed that the implementation of Teamcenter PDM in a company, improves efficiency of managing product information, eliminating time working with search, verification and correction of documentation, while ensuring the uniqueness and completeness of the product data.

  9. Experimental investigation of hydrogen embrittlement of 65 Mn steel with small punch testing method

    International Nuclear Information System (INIS)

    The hydrogen embrittlement of the 65 Mn used as the high strength spring material in Nuclear Power Plant is investigated with small punch testing method. During cathode hydrogen charging with the current density of 1 mA, 4 mA, 10 mA and 20 mA, the hydrogen atom is absorbed, diffused, segregated in the metal which causing the initiation of the brittle cracks. The specimens are punched after charging with small punch testing method. It is found that the maximum loading level, the total energy, the critical fracture strain and fracture stress reduce with the increment of the current density which means the strength and toughness reduce. The macro fracture surface changes from the ductile fracture to the typical brittle fracture and the micro fracture properties change from the ductile voids to the intergranular brittle fracture. The hydrogen concentrations in the metal were analyzed with theoretical model. It was found with the increment of the current density, the hydrogen concentration increases. (authors)

  10. Tensile-shear correlations obtained from shear punch test technique using a modified experimental approach

    2009-09-01

    Shear punch testing has been a very useful technique for evaluating mechanical properties of irradiated alloys using a very small volume of material. The load-displacement data is influenced by the compliance of the fixture components. This paper describes a modified experimental approach where the compliances of the punch and die components are eliminated. The analysis of the load-displacement data using the modified setup for various alloys like low carbon steel, SS316, modified 9Cr-1Mo, 2.25Cr-1Mo indicate that the shear yield strength evaluated at 0.2% offset of normalized displacement relates to the tensile YS as per the Von Mises yield relation ( σys = 1.73 τys). A universal correlation of type UTS = mτmax where m is a function of strain hardening exponent, is seen to be obeyed for all the materials in this study. The use of analytical models developed for blanking process are explored for evaluating strain hardening exponent from the load-displacement data. This study is directed towards rationalizing the tensile-shear empirical correlations for a more reliable prediction of tensile properties from shear punch tests.

  11. Repetitive forging (RF) using inclined punches as a new bulk severe plastic deformation method

    International Nuclear Information System (INIS)

    A new bulk severe plastic deformation method based on repetitive forging (RF) using inclined punches is proposed. This process consists of two half cycles. In the first half cycle, a square cross section deforms to parallelogram by forging with two inclined punches, and the parallelogram cross section is forged back to square using two flat punches in the second half cycle. This method was applied to commercially pure copper and significant grain refinement was achieved after four passes of RF. The results showed that significant improvement in the mechanical properties was obtained. Notable increase of yield and ultimate strengths corresponding to 358 MPa and 381 MPa after four passes of RF from the initial values of 121 MPa and 230.5 MPa is detectable. Microhardness increases to about 100 Hv after four passes of RF from the initial value of 53 Hv. Finite element (FE) results illustrate that RF is able to impose extremely high plastic strains to the materials. In the RF process, the processed samples have the same dimensions and geometry as those of the initial sample without any waste material and there is no need for back pressure.

    1987-06-01

    Three patients with chronic osteoma cutis secondary to acne vulgaris were treated with the dermabrasion-Loo-punch-excision technique. Under regional nerve block with lidocaine-bipuvacaine (50:50) a uniform dermabrasion was performed across the entire face, including the hairline and 1 cm below the jawline. This exposed the foci of osteoma cutis. Then the appropriate sized Loo punch (usually the 2.0- or the 2.5-mm punch) was used to excise the bluish-gray miliary lesions. The majority of the foci were removed in one operation. Following excision, the lesions were closed with 7-0 prolene suture. To prevent crust formation postoperatively, Aloe-vera-soaked polyethylene oxide gel dressings (Vigilon) were changed twice daily following an ice water compress. Sutures were removed rapidly in 5 to 7 days to prevent the appearance of suture lines. Although one patient required an additional procedure, the cosmetic results were excellent. Only a few small residual blue "dot" lesions remained in these three cases. PMID:2953769

    Photogates are probably the most commonly used electronic instruments to aid experiments in the field of mechanics. Although they are offered by many manufacturers, they can be too expensive to be widely used in all classrooms, in multiple experiments or even at home experimentation. Today all computers have a sound card - an interface for analogue signals. It is possible to make very simple yet highly accurate photogates for cents, while much more sophisticated solutions are also available at a still very low cost. In our paper we show several experimentally tested ways of implementing sound card photogates in detail, and we also provide full-featured, free, open-source photogate software as a much more efficient experimentation tool than the usually used sound recording programs. Further information is provided on a dedicated web page, www.noise.physx.u-szeged.hu/edudev.

    Full Text Available Introduction: cardiovascular diseases (CVD are the major component of premature mortality, generate disability and are a relevant source of cost. The growing incidence of CVD is associated with lifestyle and other modifiable risk factors. Prevention and preclinical detection of CVD reduce morbidity and mortality. Type 2 diabetes is associated with a substantially increased risk of cardiovascular disease. Objective: the aim of the study was to evaluate the health economic consequence of medical therapy with atorvastatin for primary prevention of major cardiovascular events in patients with type 2 diabetes in Italy. Materials and method: in order to reach our objective we drew clinical information from the CARDS study. This economic evaluation was carried out conducting a cost/effectiveness analysis from the perspective of National Health Service (NHS. The analysis was applied to a time horizon in conformity with the observational period adopted in the CARDS study (3.9 years. An incremental cost/effectiveness ratio (ICER was calculated and is expressed as cost per life years gained (LYG. In order to test the robustness of the results, a one-way sensitivity analysis was performed. Results: the total cost of atorvastatin therapy over 3.9 years amounts to around 1.5 million of euros per 1,000 patients. The total cost of adding atorvastatin to standard care in people treated for primary prevention of major cardiovascular events in type 2 diabetes as those involved in the CARDS study would entail an additional cost of about 1,2 million of euros per 1,000 patients treated per 3.9 years, with an incremental cost/effectiveness ratio (ICER equivalent to 36,566 euros per patient per LYG. Discussion: the current study is the first economic evaluation of CARDS study to the Italian situation. The results of the current study show that hypolipemic therapy with atorvastatin 10 mg in diabetic individuals is to be considered cost effective.

    The rh-flash card main purpose is to convert and store the image of the analog data present at input into an output buffer, namely in a given timing window besides a stop signal (like a digital oscilloscope). It is conceived in VME format 1U wide with an additional connector. Novelty of this card is its ability to sample at a high frequency, due to flash coders, and this at a high repetition rate. To do that the card allows the storage of the data considered 'useful' and that is done by storing only the data exceeding a certain threshold. This can be useful for instance for viewing peaks in a spectrum, and obtaining their relative location. The goal is to stock and process the data sampled before and after the arrival of a stop signal (what entails a storage depth). A threshold is defined and any peak exceeding its level will really be stored in the output buffer which is readable through the VME bus. The peak values will be stored as well as m preceding and n subsequent values (both programmable). Obviously, if the threshold is zero the system of data processing is off and all data will be stored. The document is structured on six sections titled: 1. Description; 2. Specifications; 3.

    2011-06-01

    Full Text Available Student population is a very interesting and important segment of the market to the marketing practitioners involved in card business. The services and products offered by card issuers to students are created with a view to attracting the kind of users who will grow accustomed to a long-term, loyal use of a chosen card brand, i.e. beyond the point at which they complete their academic education. This paper describes the exploratory research on card products designed for the student population which was conducted in the Republic of Croatia. Student awareness of card products and their habits associated with card use were also examined. Additional areas of research were student attitudes and perceptions with regard to card products and to the appeal of the marketing communications which target this specific market segment. Results showed that the majority of students hold debit cards of the banks in which they have their current accounts. Students use cards actively, most of all for the purpose of withdrawing cash at automated teller machines (ATMs and least of all for Internet purchases. They assess card use as being simple, and card holders are also aware of the various benefits provided through it. However, the recall of advertisements for card products point to the conclusion that card issuers do not communicate with students in a manner which the latter would find appealing.

  1. Discount medical cards: innovation or illusion?

    Kofman, Mila; Libster, Jennifer; Bangit, Eliza

    2005-03-01

    Discount medical cards have come under increasing scrutiny by regulators and law enforcement officials as a result of mounting consumer-reported problems. For their study, the authors tested five cards available in the Washington, D.C., metro area; interviewed card company representatives, state attorneys general insurance regulators, and insurance agents; and reviewed court and administrative actions. While some cards provide a measure of value, other cards were found to have serious drawbacks, including: high-pressure sales tactics; misleading or inaccurate promotion; exaggerated claims of savings; difficulty finding participating doctors; and providers who failed to give cardholders promised discounts. Some discount card companies are seeking to reform the market through a trade association and voluntary code of conduct. Still, legislative and regulatory interventions will be needed to protect consumers in an unregulated and growing market. PMID:15765567

  14. Fabrication of a micro-punching head using LIGA and stacking processes

    International Nuclear Information System (INIS)

    A simple stacking process to fabricate microstructures with a high aspect ratio of 30 is presented in this study. For the x-ray absorption of a substance, an analytical model of the absorption dosage (exposure dosage) along a depth of x is developed. It can accurately estimate the time and dosage required for exposure. Based on the calculated result, 1 mm thick PMMA (polymethylmethacrylate) photoresist with a separate gold (Au)/graphite mask is exposed using x-rays followed by a developing process. Then a stacking process is applied for these 1 mm thick PMMA microstructures to form a microstructure with a high aspect ratio. With this stacking method, a PMMA microstructure with a height of 3 mm has been fabricated. In addition, a nickel–cobalt (Ni–Co) alloy electroplating process is applied to fabricate a metallic mold with high hardness. The hardness of the mold by electroforming is the key factor to the quality of the micro-punch process. As an integrated micro-punch head for IC leadframes, the hardness should be higher than 500 Vickers hardness (Hv). In addition, it was found experimentally that changing the ratio of Ni sulfamate to Co sulfamate can affect the deposit hardness and internal stress. The deposit internal stress varies with Co content. Thus, it is necessary to add a stress reducer to improve the hardness and reduce internal stress. A hardness of the mold of 550–560 Hv with 26–28 wt.% of Co and zero internal stress have been made successfully after adding a stress reducer. With this electroplating technique, a micro-punching head with high hardness and high aspect ratio can be fabricated by LIGA technology

    2011-08-01

    This study tests the validity of hypotheses about the interpretations of Rorschach father/mother cards by having subjects select the cards. The results showed that regardless of the subject's gender, Card IV is far more often selected as the father card. However Card VII is not more often chosen as the mother card, if anything, the Color Cards are usually selected. The result of a correspondence analysis suggest that a certain combination of father and mother cards is more often selected. When the frequency of card selection is applied to the cluster of cards obtained in the study of Fukui et al (2008), the mother card is predominantly selected from the feminine/maternity-cards cluster. However, the father card was selected equally often from three clusters, indicating variation of the father figure. The results indicate the predominance of Card IV as the father card, and also confirm the lack of individuality with Card VII. Therefore, Card IV fulfills prerequisites for the father card hypothesis, while Card VII does not meet the criteria. The results do not support the validity of the hypothesis about the mother card interpretation. PMID:21919302

  6. On yield line estimates of the punching strength of full panel unbonded post-tensioned flat slabs at internal columns

    Directory of Open Access Journals (Sweden)

    Shodolapo Oluyemi Franklin

    2010-12-01

    Full Text Available In this study, the yield line method of analysis is used to calculate the ultimate punching capacity of ten full panel, unbonded post-tensioned slabs, six of which were subject to combined vertical and transfer of moment loading. It is found that the method estimates to within 10% the failure loads for cases involving purely vertical loading. However the predictions for those slabs subjected to moment transfer are not consistent. An important consideration in this regards was the presence or otherwise of ordinary bonded reinforcement at the critical positive moment regions of the slabs. It is suggested that alternative flexural mechanisms of punching failure should be utilized in lieu of yield line theory to obtain reliable estimates of the punching capacity.

  10. Evaluating the mechanical behavior of hot rolled Al/alumina composite strips using shear punch test

    International Nuclear Information System (INIS)

    The evaluation of mechanical properties, like yield and ultimate shear strengths from shear punch tests, is important when availability of material, is limited. A shear punch test setup was built, and the mechanical properties of different strips of hot rolled pure aluminum, post-rolling annealed pure aluminum, as-milled pure aluminum, and 4 wt% Al2O3 were investigated. The materials were first manufactured using powder metallurgy and then processed by hot rolling procedure. Microstructures of the samples were investigated by optical and scanning electron microscopes. It was found that by increasing alumina content in the matrix, shear strength and hardness were increased; also, the percentage of shear elongation was decreased. The results, also, indicated that by applying mechanical milling on pure aluminum powders before the hot rolling process, shear strength and hardness increased more than other samples. Moreover, shear strength was increased by increasing the amount of alumina particles in composite strips. SEM observations demonstrated that the amount of flat surface in shear failure micrographs increased by increasing the amount of shear strength and hardness

    2001-01-01

    Full Text Available Secretory leukocyte protease inhibitor (SLPI is a wellknown protease inhibitor. Its function is thought to be protease/protease-inhibitor balance. Free proteolytic activity, mainly pancreatic elastase, anionic trypsin and granulocytic elastase, has been demonstrated in faecal extracts from patients with ulcerative colitis. We wanted to verify that SLPI is actually secreted from normal human colonic mucosa. Also, we wanted to ascertain whether studies of SLPI secretion based on punch biopsies were dependent on biopsy area or on biopsy circumference. Normal colonic mucosa was sampled during surgery for colonic cancer. A total of 36 samples from four patients were used. Mucosa preparation was carried out using a punch biopsy technique, and samples of 3, 4 and 6 mm diameter were used. All media contained SLPI at varying concentrations. When expressed in terms of the sample area, the secretion per millimetre-squared seemed to decrease with increasing area. When calculated as secretion per circumference, secretion seemed to be constant. In conclusion, SLPI was secreted from normal human colonic mucosa. The SLPI secretion seemed dependent on the circumference of the biopsy rather than on the area of the biopsy.

  12. Flow localization during plane strain punch stretching of a ferrite-austenite steel

    Science.gov (United States)

    Bird, J. E.; Pollock, T.; Srivastava, S. K.

    1986-09-01

    This is an exploratory study of plastic flow and sheet forming characteristics of a 60 pct ferrite-40 pct austenite duplex stainless steel. Variations in austenite arrangement are shown to have little effect on tensile or punch stretching behavior. Flow and forming properties of the duplex alloy are dominated by its continuous ferrite phase. Flow localization during plane strain stretching over a hemispherical punch takes place at two levels of scale, by mechanisms that are physically different. Macroscopic shear bands develop as the final process of flow localization throughout the sheet as a whole. Macroscopic shear bands initiate at the surface of sheet at the edges of a localized neck and grow inward, as finite element models predict. Fracture takes place by void sheet coalescence within intersecting shear bands. These bands grow in from opposite sides of the sheet. Macroscopic shearing limits ductility during plane strain thinning. Row localization takes place also at the microscopic level within individual grains of the two-phase alloy. Coarse slip bands develop within individual grains of ferrite, and deformation twins develop in austenite as plastic flow takes place. Bands of in-homogeneous flow that develop on the microscopic scale form as an inherent part of the crystalline deformation mechanism of individual grains.

    A point card compatible automatic vending machine for canned drinks is developed, which provides drink manufacturers with a powerful tool to acquire selling sites and attract consumers. Since the machine is equipped with a device to handle point cards, regular customers have increased and sales have picked up. A point card issuing device is also installed, and the new machine issues a point card whenever a customer wants. The drink manufacturers are evaluating high of the vending machine because it will contribute to the diffusion of the point card system and because a sales promotion campaign may be conducted through the vending machine for instance by exchanging a fully marked card with a giveaway on the spot. In the future, a bill validator (paper money identifier) will be integrated even with small size machines for the diffusion of point card compatible machines. (translated by NEDO)

    Full Text Available Due to a rapid growth in the e-commerce technology, the use of credit cards has increased. As credit card becomes the most popular mode of payment for both online as well as normal purchase, cases of credit card fraud also rising. Financial fraud is increasing significantly with the development of modern technology and the global superhighways of communication, resulting in the loss of billions of dollars worldwide each year. The fraudulent transactions are scattered with genuine transactions and simple pattern matching techniques are not often sufficient to detect those frauds accurately. Implementation of efficient fraud detection systems has thus become imperative for all credit card issuing banks to minimize their losses. Many modern techniques were proposed & implemented in literature, they have their own advantages and disadvantages. We proposed hybrid approach used in credit card fraud detection mechanism.

    Full Text Available This paper examines empirically antecedents of the credit card debts in young consumers in Malaysia. We examine whether easy access to credit card, credit card related knowledge, aggressive promotion by credit card industry, low minimum payment requirement and attitude towards credit cards influence credit card debts in the younger generation. Regression model was used to meet the objectives. These findings based on a sample of 240 young credit card holders, show that the factors that affect credit card debts are credit card related knowledge, aggressive promotion by credit card industry and low minimum payment requirements. These findings also provide insights for both bank management and policy-makers to improve the bank performance in terms of credit card debts.

    Durant, P; Bérubé, J; Lavoie, G; Gamache, A; Ardouin, P; Papillon, M J; Fortin, J P

    1995-01-01

    The Quebec Health Smart Card Project is advocating the use of a memory card software server[1] (SCAM) to implement a portable medical record (PMR) on a smart card. The PMR is viewed as an object that can be manipulated by SCAM's services. In fact, we can talk about a pseudo-object-oriented approach. This software architecture provides a flexible and evolutive way to manage and optimize the PMR. SCAM is a generic software server; it can manage smart cards as well as optical (laser) cards or other types of memory cards. But, in the specific case of the Quebec Health Card Project, SCAM is used to provide services between physicians' or pharmacists' software and IBM smart card technology. We propose to expose the concepts and techniques used to provide a generic environment to deal with smart cards (and more generally with memory cards), to obtain a dynamic an evolutive PMR, to raise the system global security level and the data integrity, to optimize significantly the management of the PMR, and to provide statistic information about the use of the PMR.

  14. Relativistic Hydrodynamics on Graphic Cards

    CERN Document Server

    Gerhard, Jochen; Bleicher, Marcus

    2012-01-01

    We show how to accelerate relativistic hydrodynamics simulations using graphic cards (graphic processing units, GPUs). These improvements are of highest relevance e.g. to the field of high-energetic nucleus-nucleus collisions at RHIC and LHC where (ideal and dissipative) relativistic hydrodynamics is used to calculate the evolution of hot and dense QCD matter. The results reported here are based on the Sharp And Smooth Transport Algorithm (SHASTA), which is employed in many hydrodynamical models and hybrid simulation packages, e.g. the Ultrarelativistic Quantum Molecular Dynamics model (UrQMD). We have redesigned the SHASTA using the OpenCL computing framework to work on accelerators like graphic processing units (GPUs) as well as on multi-core processors. With the redesign of the algorithm the hydrodynamic calculations have been accelerated by a factor 160 allowing for event-by-event calculations and better statistics in hybrid calculations.

  15. Insider protection: A report card

    International Nuclear Information System (INIS)

    Enhanced security measures against external threats (e.g., terrorists, criminals) have been implemented at most facilities that handle special nuclear material, classified information, or other assets critical to national security. Attention is now focusing on insider protection, and safeguards managers are attempting to provide balanced protection against insider and outsider threats. Potential insider threats include attempts by facility employees to steal special nuclear material (SNM), to cause a radiological hazard to the public, to sabotage critical facilities, or to steal property or classified information. This paper presents a report card on the status of insider protection at Department of Energy and Nuclear Regulatory Commission-licensed facilities, with emphasis on SNM theft. The authors discuss the general trends in insider protection and the limitations of protection measures currently in use. They also discuss the most critical needs for improved procedures, technology, analytical tools, and education for safeguards personnel

    2016-05-01

    The main purpose of this paper is to investigate the influence of punching process on residual stress and magnetic domain structure. The residual stress in non-oriented silicon steel after punching process was measured by nanoindentation. The maximum depth was kept constant as 300 nm during nanoindentation. The material around indentation region exhibited no significant pile-up deformation. The calculation of residual stress was based on the Suresh theoretical model. Our experimental results show that residual compressive stress was generated around the sheared edge after punching. The width of residual stress affected zone by punching was around 0.4-0.5 mm. After annealing treatment, the residual stress was significantly decreased. Magnetic domain structure was observed according to the Bitter method. The un-annealed sample exhibited complicated domain patterns, and the widths of the magnetic domains varied between 3 μm and 8 μm. Most of the domain patterns of the annealed sample were 180°-domains and 90°-domains, and the widths of the domains decreased to 1-3 μm.

  10. Simulation of a drop onto a punch of a transport container for fuel assemblies

    International Nuclear Information System (INIS)

    International regulations require that a container for the transport of nuclear material has to sustain a 1-meter drop onto a cylindrical punch made of mild steel. It has to be shown that, at all times, the confinement of the radioactive contents is guaranteed. Also, any deformation of the internal arrangement has to be avoided or at least controlled in order to ensure the sub-criticality of the fuel assemblies at all times. LS-DYNA3D models of representative cross sections of two baskets have been developed. The finite element analysis has been validated by successfully calibrating it with an actual drop test. Thus, the most pessimistic configuration of the basket of the package was determined and used for all subsequent safety case studies

    Complete manufacturing cycle on the production of parts for superconducting single-cell cavity (half-cells, drift tubes and flanges) has been executed. Half-cells of the cavities were made by the method of hydropercussion punching which has a number of advantages in comparison with instrumental stamping technique. Experimentally for the first time the diagram of hydropercussion stamping of ultrapure niobium has been obtained and the key parameters of the process which provide the complete deep-drawing of workpiece have been defined: ultimate degree of extraction is 1.92 at the specific impact energy 0.42 MJ/m2. The deviations of half-cells dimensions do not exceed 0.1 mm from the nominals. All the necessary fixtures for all manufacturing steps have been produced. The parameters of machining of the parts of niobium cavities before the welding have been determined experimentally

  12. An inverse method for determining flow stress by small punch testing

    International Nuclear Information System (INIS)

    An inverse method is presented to obtain material's flow properties by using small punch test. This procedure employs, as the objective function of inverse analysis, the balance of measured load-displacement response and calculated one during deformation. In order to guarantee convergence to global minimum, simulated annealing method was adopted to optimize the current objective function. In addition, artificial neural network was used to predict the load-displacement response under given material parameters which is the most time consuming and limits applications of global optimization methods to these kinds of problems. By implementing the simulated annealing for optimization along with calculating load-displacement curve by neural network, material parameters were identified irrespective of initial values within very short time for simulated test data. We also tested the present method for error-containing experimental data and showed that the flow properties of material were well predicted

  13. Creep damage in small punch creep specimens of Type 304 stainless steel

    International Nuclear Information System (INIS)

    Small punch creep tests on Type 304 stainless steel have been performed at 650 deg. C. Based on these tests, a finite element model, with modified Kachanov-Rabotnov creep damage constitutive equations, was established. The variation of central deflection and creep strain with time and the evolution of creep damage under constant loads were analysed by using the finite element model. The central creep deflection curves in the specimens were obtained at different loads in both tests and simulations and have three different stages, similar to conventional creep tests. There is good agreement between experimental results and simulation data. The creep damage at the central part is high, and localization of damage is obvious. Initial failure occurs at the bottom surface, about 0.8 mm away from the centre which agrees well with the finite element mode observation

    DEFF Research Database (Denmark)

    Ellegaard, Peter

    2006-01-01

    The focus of this paper is to describe the idea and the theory behind a finite-element model developed for analysis of timber trusses with punched metal plate fasteners (nail plates). The finite-element model includes the semirigid and nonlinear behavior of the joints (nonlinear nail and plate...... elements) and contact between timber beams, if any (bilinear contact elements). The timber beams have linear-elastic properties. The section forces needed for design of the joints are given directly by the finite-element model, since special elements are used to model the nail groups and the nail plate...... area over the joint lines. The finite-element model is based on the Foschi model, but with further improvements. After the theory of the model is described, results from experimental tests with two types of nail plate joints are compared with predictions given by the model. The model estimates the...

    Kato, Taichiro; Komazaki, Shin-ichi; Kohno, Yutaka; Tanigawa, Hiroyasu; Kohyama, Akira

    2009-04-01

    Type IV creep damage has recently been a worldwide issue for high Cr ferritic steels. The small punch (SP) creep test has been successfully applied to evaluate this damage of low alloy ferritic steel by the author's group. However, the heat affected zone (HAZ) of fusion reactor material welded by electron-beam (EB) welding is so thin that it is not easy to evaluate its mechanical properties by the conventional SP test. In this study, the SP test using a further miniaturized specimen was applied to the EB welded joint of reduced activation ferritic steel (RAFs), for evaluating high-temperature tensile properties of the HAZs. As the result, the σy and σB of the tempered HAZ at 873 K were estimated to be as low as 275-300 MPa and 325-340 MPa, respectively.

    1998-12-31

    The presentation deals at length with the relationship between the Small Punch, SP, test transition temperature Tsp, behaviour and those displayed by the conventional Charpy Fracture Appearance Transition Temperature, FATT, obtained from large test specimens. Essentially it was demonstrated that the total test temperature range trends could reasonably be described by a non-linear expression such as FATT varied inversely with the square of the Tsp. Finally when the Tsp against FATT trends were separated into different steel classes an encouraging picture emerged inasmuch that a reasonable amount of data exhibited good agreement with the predicted effects of grain size. Fractographic details were also discussed and strong effects of strain or loading rates were identified. (orig.) 19 refs.

  18. Study of the mechanical properties of the electric power station components: the punch test

    International Nuclear Information System (INIS)

    The aging of the electric production park implies an increasing need of knowledge concerning the evolution of the mechanical properties of its components. With regard to this problem, the availability in material is more and more small. This work proposes to characterize these properties through a mechanical test called Punch test. The main characteristic of this test is to use very small volume samples. The development of this test has been carried out by the study of a 15 MDV 4-05 steel coming from a steam drum of a thermal power plant after 145000 hours of service. At first, we have measured the influence of the parameters of this test. Then, the study has dealt more particularly on the transition temperature of the material. With the finite element simulation method, the strain hardening coefficient of the material has been determined. (O.M.)

  19. Fracture toughness evaluation of fusion reactor structural steels at low temperatures by small punch tests

    International Nuclear Information System (INIS)

    A small punch (SP) test using miniaturized specimens has been performed for cryogenic austenitic steels at 4.2, 77 and 293 K to evaluate fracture toughness in a fusion material program. An SP testing cryostat for load versus deflection curve measurements has been successfully constructed. A universal relationship between valid fracture toughness, JIC, and equivalent fracture strain, anti εqf, for austenitic steels at different test temperatures has been confirmed and empirical parameters for that relation have been determined using a linear regression model. A linear correlation between valid JIC and anti εqf has been clarified for austenitic steels at low temperatures, where the regression coefficient is found to be 845 kJ/m2. Using the results of the SP test above room temperature, a new attempt at statistical analysis has been proposed to estimate the relative change in fracture toughness due to neutron irradiation.

Despite this similarity, current design codes provide distinctly different methods for the design of shear reinforcement in the two situations. For example, the Eurocode method for beam shear design is founded on the theory of rigid plasticity....... To design shear reinforcement in slabs, on the other hand, the engineer must settle for an empirical equation. The aim of the study reported is to demonstrate that it is possible in a simple manner to design shear reinforcement in slabs based on the same rigid-plasticity foundation as for beam shear...... design. For this purpose, an extension of the upper-bound crack sliding model is proposed. This involves analysis of sliding mechanisms in yield lines developed both within and outside the zone with shear reinforcement. Various types of headed shear studs were considered. The results obtained using the...

  2. Tissue Microarray Technology for Molecular Applications: Investigation of Cross-Contamination between Tissue Samples Obtained from the Same Punching Device

    2015-04-01

    Full Text Available Background: Tissue microarray (TMA technology allows rapid visualization of molecular markers by immunohistochemistry and in situ hybridization. In addition, TMA instrumentation has the potential to assist in other applications: punches taken from donor blocks can be placed directly into tubes and used for nucleic acid analysis by PCR approaches. However, the question of possible cross-contamination between samples punched with the same device has frequently been raised but never addressed. Methods: Two experiments were performed. (1 A block from mycobacterium tuberculosis (TB positive tissue and a second from an uninfected patient were aligned side-by-side in an automated tissue microarrayer. Four 0.6 mm punches were cored from each sample and placed inside their corresponding tube. Between coring of each donor block, a mechanical cleaning step was performed by insertion of the puncher into a paraffin block. This sequence of coring and cleaning was repeated three times, alternating between positive and negative blocks. A fragment from the 6110 insertion sequence specific for mycobacterium tuberculosis was analyzed; (2 Four 0.6 mm punches were cored from three KRAS mutated colorectal cancer blocks, alternating with three different wild-type tissues using the same TMA instrument (sequence of coring: G12D, WT, G12V, WT, G13D and WT. Mechanical cleaning of the device between each donor block was made. Mutation analysis by pyrosequencing was carried out. This sequence of coring was repeated manually without any cleaning step between blocks. Results/Discussion: In both analyses, all alternating samples showed the expected result (samples 1, 3 and 5: positive or mutated, samples 2, 4 and 6: negative or wild-type. Similar results were obtained without cleaning step. These findings suggest that no cross-contamination of tissue samples occurs when donor blocks are punched using the same device, however a cleaning step is nonetheless recommended. Our

    In his book "Mathematical Mind-Benders", Peter Winkler poses the following open problem, originally due to the first author: "[In the game Peer Pressure,] two players are dealt some number of cards, initially face up, each card carrying a different integer. In each round, the players simultaneously play a card; the higher card is discarded and the lower card passed to the other player. The player who runs out of cards loses. As the number of cards dealt becomes larger, what is the limiting probability that one of the players will have a winning strategy?" We show that the answer to this question is zero, as Winkler suspected. Moreover, assume the cards are dealt so that one player receives r >= 1 cards for every one card of the other. Then if r phi, it is one.

    Melanoma in darker-pigmented individuals often develops in an acral lentiginous fashion on the foot. After surgical removal of a tumor at this site, repair of the wound can be challenging. This is because there is an insufficient local skin pool and lack of mobility of the skin in this area. Moreover, functional aspects such as walking and weight bearing should be considered. We performed a combination treatment of negative pressure wound therapy (NPWT) and punch grafting on 15 patients, after wide excision of acral lentiginous melanomas on the foot, and compared these to 26 patients who underwent either secondary intention healing (SIH, n = 13) or NPWT (n = 13) alone. The punch grafting with NPWT group showed significantly shorter healing times than those of the other two groups. Evaluation of completely healed wounds using the Vancouver Burn Scar Assessment Scale revealed that the punch grafting group had mean values better, or comparable, to the SIH or NPWT group in four of the five scales (except pigmentation). As for complications, only one patient developed a wound infection after punch grafting. Further, by utilizing NPWT for fixation of punch grafts, it was possible to treat all subjects as outpatients after punch grafting. These results show that a combination treatment of NPWT and punch grafting is an excellent therapeutic option for post-wide excision wounds on the feet, with significantly shortened healing times and favorable cosmetic outcomes.

  9. Problem and solution of tally segment card in MCNP code

    International Nuclear Information System (INIS)

    Wrong results may be given when FS card (tally segment card) was used for tally with other tally cards in Monte Carlo code MCNP. According to the comparison of segment tally results which were obtained by FS card of three different models of the same geometry, the tally results of fuel regions were found to be wrong in fill pattern. The reason is that the fuel cells were described by Universe card and FILL card, and the filled cells were always considered at Universe card definition place. A proposed solution was that the segment tally for filled cells was done at Universe card definition place. Radial flux distribution of one example was calculated in this way. The results show that the fault of segment tally with FS card in fill pattern could be solved by this method. (authors)

  10. Evaluation of mechanical properties of structural materials by small punch test

    International Nuclear Information System (INIS)

    Small punch(SP) test method was applied to evaluate the mechanical properties of structural steels for nuclear power plant components. The yield strength of several nuclear structural steels was estimated based on the detailed examination of initial deformation characteristics during the SP test. In addition, the ductile-brittle transition temperature(DBTT) of heat-treated SA508 Cl. 3 nuclear pressure vessel steel was correlated with the temperature dependence of the SP characteristics. Finally, the SP test was performed on duplex stainless steel to estimate the extent of thermal aging embrittlement. Initial deformation behavior during small punch test was investigated using two SP specimen sizes, 10x10x0.5 mm3 and 10x10x0.25 mm3 by finite element analysis and by experiments with heat-treated SA508 Cl. 3 and 12Cr steel. The increase of specimen thickness resulted in a deviation from the initial linearity of the load-displacement curve at higher load. The deviation was attributed to different causes, namely loss of the constraint by the surrounding material and radial propagation of plastic bending deformation for 0.5 and 0.25mm specimens, respectively. The causes for the transition of deformation mode were identical irrespective of material strength and work-hardening rate in the range of yield strength about 400 to 900 MPa. Based on the invariance of the deformation mode, a distinct linear relationship between the load at the deviation from the linearity and the yield stress was predicted by finite element analysis and compared with the experimental results. The validity of using the SP test for the DBTT evaluation of SA508 Cl. 3 steel was investigated. It was clearly observed that the variation of load-displacement curves with temperature was accompanied by the change of fracture mode and appearance. The temperature dependence of the SP characteristics well described the toughness degradation which was made by heat treatment. The SP energy was selected to

  13. Numerical And Experimental Analysis Of The Process Of Aviation Drawpiece Forming Using Rigid And Rubber Punch With Various Properties

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available This paper presents the results of the numerical analysis and experimental research of the forming process of aviation drawpiece made from 0.6 mm thick Inconel 625 sheet metal. First phase of testing was conducted using rigid steel tools for drawpiece forming. Results of conducted simulations show that during rigid tool forming, the middle of the drawpiece losses stability. In consequence, rigid tool forming leads to the formation of unacceptable wrinkles on the drawpiece. Subsequent experimental research confirmed wrinkles of the metal drawpiece in this area. It was assumed that in order to eliminate this negative phenomenon, minor changes in technology and tool construction would have to be made. The drawpiece will be shaped by means of a flexible tool, than re-shaped using rigid tools. In the second phase of the research, tooling design changes have been made. They consisted of replacing the steel punch with a specially designed stamp susceptible for deformation. FEM numerical simulations were performed for flexible punch forming made of polyurethane elastomer with different hardness (50, 70, 85 and 90 Sh A. On their basis, the effect on the mechanical characteristics of the elastomeric drawing process and the formation of wrinkles was shown. They can be effectively eliminated by the use of a punch with hardness of 90 Sh A, which has also been confirmed by experimental research. In addition, the paper presents a comparative analysis of the deformations in selected actual drawpiece areas and in the elastomeric punch with hardness 90 Sh A computer model. The actual drawpiece deformation schedule and the values were determined using photogrammetric system Argus v.6.3., while the computer modeled drawpiece was based on FEM calculations performed in the MARC / Mentat system. In conclusion the difficulties as well as the advantages and disadvantages in determining the deformation of sheet metal parts were indicated using photogrammetric system

    A Link Source Card (LSC) has been developed which employs Gigabit Ethernet as the physical medium. The LSC is implemented as a mezzanine card compliant with the S-Link specifications, and is intended for use in development of the Region of Interest Building (ROIB) in the Level 2 Trigger of ATLAS. The LSC will be used to bring Region of Internet Fragments from Level 1 Trigger elements to the ROIB, and to transfer compiled Region of Interest Records to Supervisor Processors. The card uses the LSI 8101/8104 Media Access Controller (MAC) [1] and the Agilent HDMP-1636 Transceiver. An Altera 10K50A FPGA [2] is configured to provide several state machines which perform all the tasks on the card, such as formulating the Ethernet header, read/write registers in the MAC, etc. An on-card static RAM provides storage for 512K S-Link words, and a FIFO provides 4K buffering of input S-Link words. The LSC has been tested in a setup where it transfers data to a NIC in the PCI bus of a PC.

  17. Universality of the diffusion wake from stopped and punch-through jets in heavy-ion collisions

    Betz, Barbara; Noronha, Jorge; Torrieri, Giorgio; Gyulassy, Miklos; Mishustin, Igor; Rischke, Dirk H.

    2009-03-01

    We solve (3+1)-dimensional ideal hydrodynamical equations with source terms that describe punch-through and fully stopped jets to compare their final away-side angular correlations in a static medium. For fully stopped jets, the backreaction of the medium is described by a simple Bethe-Bloch-like model that leads to an explosive burst of energy and momentum (Bragg peak) close to the end of the jet's evolution through the medium. Surprisingly enough, we find that the medium's response and the corresponding away-side angular correlations are largely insensitive to whether the jet punches through or stops inside the medium. This result is also independent of whether momentum deposition is longitudinal (as generally occurs in pQCD energy loss models) or transverse (as the Bethe-Bloch formula implies). The existence of the diffusion wake is therefore shown to be universal to all scenarios where momentum as well as energy is deposited into the medium, which can readily be understood in ideal hydrodynamics through vorticity conservation. The particle yield coming from the strong forward moving diffusion wake that is formed in the wake of both punch-through and stopped jets largely overwhelms their weak Mach cone signal after freeze-out.

  18. Assessment of irradiation-hardening on Eurofer97' and Zircaloy 2 with punch tests and finite-element modeling

    International Nuclear Information System (INIS)

    We present an assessment of the mechanical constitutive behavior after irradiation for a tempered martensitic steel, Eurofer97', and for Zircaloy by means of small-ball punch tests. For that purpose we use a finite-element model of the punch test device. We take advantage of the model to infer the alloy mechanical constitutive behavior after irradiation. We show that a necessary matching between the experimental and calculated force-deflection curves allows choosing consistently among the proposed constitutive behaviors. We discuss also the limitations of this method. For Zircaloy a complete description of the constitutive behavior in the unirradiated or irradiated condition was not possible in the framework of anisotropic plastic potentials and associated flow rules, since this demands to fully characterize experimentally the anisotropic yield surface and its evolution with plastic strain during punch deformation. However, an approximate description of the initial yielding anisotropy using Hill plastic potential is possible (although not unique) and necessary before an assessment of the irradiation-hardening can be done on a safe basis. Developing a conventional (non-axisymmetric) three-dimensional model was mandatory in order to deal with the problem of anisotropy in Zircaloy

  19. Development of a remote controlled small punch testing machine for nuclear fusion research

    International Nuclear Information System (INIS)

    An accelerator-driven deuterium-lithium (d-Li) stripping reaction-type neutron source, such as the International Fusion Materials Irradiation Facility(IFMIF) planned by the International Energy Agency is recognized as one of the most promising facility to obtain test environments of high-energy neutrons for fusion reactor materials development. The limitation on the available irradiation volume of the irradiation facility requires the development of the small specimen test techniques (SSTT). Application of SSTT to evaluate the degradation of various components in the light water reactor for the life extension is expected to be also quite beneficial. A remote-controlled testing machine for the Small Punch (SP) and miniaturized tensile tests was developed at the hot laboratory of the Japan Materials Testing Reactor (JMTR). The machine is designed for testing at temperatures ranging between 93 K and 1123 K to evaluate the temperature dependence of the strength of materials including the embrittlement at low temperatures and the softening at elevated temperatures in a vacuum or in an inert gas environment. The machine has been installed in a hot cell and is used for the round robin test program of the SP test method. The round robin test program was planned to identify the capability of the test method and to establish a standard test procedure. The configuration and the specifications of the test machine are introduced and the results of the round robin tests are also shown. (author)

  20. Creep damage evaluation of low alloy steel weld joint by small punch creep testing

    International Nuclear Information System (INIS)

    The effect of sampling location on SPC (Small Punch Creep) tests were investigated for weld joints to establish evaluation method of Type IV creep behavior. The SPC specimen shape was 10mm diameter and 0.5mm thick round disc prepared from weld joints of 2.25Cr-1Mo low alloy steel. It was found that the center of SPC specimen should be 2mm apart from the weld interface as the recommended sampling location. Creep damage was imposed for large weld joint specimens by axial creep loading at 620degC, 52MPa with the interrupted time fraction of 0.34, 0.45, 0.64 and 0.82.SPC samples were prepared from those damaged specimens following the recommended way described in this paper. Among the various SPC tests conducted, good relationships were found for the test condition of 625degC, 200N. Namely, good relationships were obtained both between minimum deflection rate and creep life fraction, and between rupture time and creep life fraction. Consequently, creep life assessment of Type IV fracture by SPC tests could be well conducted using the sampling location and the test condition recommended in this paper. (author)

  1. On the correlation between minimum thickness and central deflection during small punch test

    Kumar, Pradeep; Chattopadhyay, J.; Dutta, B. K.

    2016-07-01

    Present paper deals with a detailed study on the correlation between minimum thickness (t/t0) and central deflection (δ/t0). Such data are obtained during the deformation of a small punch test of miniaturized specimen. Finite element studies have been carried out to investigate the effect of various parameters which are expected to influence this correlation. The parameters under consideration are material hardening, material yield stress, coefficient of friction and initial thickness of the specimen. It is shown that the correlation remains unaffected with respect to change in material parameters. Similarly, the coefficient of friction beyond 0.2 also does not affect the correlation. However, change in thickness has significant effect on the correlation. A modification has been suggested in the existing correlation to consider the influence of thickness change. The modified correlation is then used to calculate fracture toughness using the experimental results quoted in the literature. It is shown that the modified correlation improves the fracture toughness prediction considerably.

  2. Radiation hardness of punch-through and FET biased silicon microstrip detectors

    International Nuclear Information System (INIS)

    Silicon microstrip detectors can be biased with polysilicon resistors or Field Effect Transistor (FET) biasing structures. Polysilicon resistors are radiation hard, but using the FET biasing principle reduces processing costs and can give better noise performance. A set of microstrip detectors has been manufactured with a standard radiation sensor process in order to assess the radiation hardness of punch-through and FET biasing. Eight different bias geometry designs were used in order to study the effects of bias gap lengths and strip end geometries on the detector characteristics. The test detectors were irradiated at several dose levels up to 75 kGy with a 60Co source. Initially the devices had very low oxide charge (3.1010 cm-2) and leakage current levels (60 pA per strip). The dynamic resistance was in the 1 GΩ range, which is higher than the values which can be achieved by conventional polysilicon resistors. Radiation exposure gave significant increases in the leakage current of the devices. This causes large reductions in the dynamic resistance, and detector performance will degrade. The degradation due to increased leakage current was present for all strip end geometries, and it could not be compensated by changing the gate voltage. (orig.)

    2016-08-01

    Experimental and numerical studies of hot tearing formation in steel are reported. On the one hand, an ingot punching test is presented. It consists in the application of a deformation at the surface of a solidifying 450 kg steel ingot. The experimental parameters are the displacement of the pressing tool, together with its velocity, leading to variations of a global strain rate. On the other hand, three-dimensional finite element thermomechanical modeling of the test is used. The time evolution of the strain tensor serves to compute an index to evaluate the susceptibility to create hot tears. It is based on the integration of a hot tearing criterion (HTC) that compares the local accumulation of strain with the expression of a critical value proposed in the literature. The main variable of the criterion is the brittleness temperature range (BTR) that refers to the solidification interval during which strain accumulates and creates hot cracks or tears. Detailed comparison of the simulation results with the measurements reveals the importance of the BTR for the prediction as well as excellent capabilities of the HTC to predict the formation of hot tears.

  4. The tabletting machine as an analytical instrument: qualification of the tabletting machine and the instrumentation with respect to the determination of punch separation and validation of the calibration procedures.

    Belda, P M; Mielck, J B

    1999-05-01

    The quality of the determination of punch separation in an eccentric tabletting machine equipped with two inductive displacement transducers was carefully investigated, since this tabletting machine is used as an 'analytical instrument' for the evaluation of the compression behaviour of pharmaceutical materials. For a quasistatic calibration procedure using gauge blocks, the repeatability under standard conditions and the robustness against variations in machine settings, installation conditions, equipment and methods were examined. The readings during calibration can be easily influenced by machine parameters as a result of deficiencies in the construction of the machine and in the mode of instrumentation. The poor plane-parallelism of the punch faces has a further negative effect on the accuracy of punch separation. In addition, the response at loading to lower and higher forces as during calibration was investigated. While at loading up to 100 N, the response of the system to the gauge blocks is systematically influenced by punch separation, for slow manually applied punch-to-punch loading up to 16.5 kN at a broad range of penetration depths, no significant effects were observed in the region of interest for tabletting. To get an indication of the transferability of the calibration and the determination of punch deformation to normal operating conditions, the lateral tilting of the punches during dynamic idle runs, punch-to-punch loading, and compression of microcrystalline cellulose was analyzed. A transfer of the response derived from punch-to-punch compression to tabletting conditions seems to be possible, although this must be questioned on grounds of theoretical considerations. From all the experiments performed, a total error of about +/- 30 microns must be assessed for the determination of punch separation. PMID:10382107

  5. Data card system for filmless radiography

    International Nuclear Information System (INIS)

    Data cards using the sample principles as music compact discs can store 4 MB of digital data. This is sufficient for 4 uncompressed radiographic images or 16 images with 4:1 average compression. Radiograph memory screens (stimulable phosphors) can be scanned at 1023 lines to provide the input signals. A filmless radiographic x-ray system is described which uses digital data cards of the size of common credit cards. These can be used in the same way as films are now used: placed in patient folders, copied, mailed, seen on view boxes, etc. The techniques of data acquisition, processing, compression, storage and display are described. The advantages of the system are explained in terms of economies, elimination of film (chemicals and processing), and compatibility with other data transmission methods. Suggestions are made for standardization of data storage and control so that this method may be used for other medical imaging applications, such as CT and ultrasound

    Literature and previous studies show that creative play is easy to emerge when children interact with tangible, low-tech toys and games than with digital games. This paradoxical situation is linked to the long-standing problem of end-users (or players) authoring of digital contents and systems. We...... propose a new scenario in which trading card games help making sense and re-design computer games, to support players express themselves aesthetically and in a highly creative way. Our aim is to look for a middle ground between players becoming programmers and simply editing levels. The main contributions...... are to show how card games can represent digital games, how playful play can emerge in card games and digital games, and to begin defining a new way to express game behavior without the use of universal programming languages....

    1998-04-01

    Print-on-demand is currently a major trend in the production of paper based documents. This fully digital production philosophy will likely have ramifications also for the secure identification document market. Here, plastic cards increasingly replace traditionally paper based security sensitive documents such as drivers licenses and passports. The information content of plastic cards can be made highly secure by using chip cards. However, printed and other optical security features will continue to play an important role, both for machine readable and visual inspection. Therefore, on-demand high resolution print technologies, laser engraving, luminescent pigments and laminated features such as holograms, kinegrams or phase gratings will have to be considered for the production of secure identification documents. Very important are also basic optical, surface and material durability properties of the laminates as well as the strength and nature of the adhesion between the layers. This presentation will address some of the specific problems encountered when optical security features such as high resolution printing and laser engraving are to be integrated in the on-demand production of secure plastic card identification documents.

  12. Card products market in the Republic of Croatia

    Directory of Open Access Journals (Sweden)

    Ivana Šučur

    2007-12-01

    Full Text Available Card business in the Republic of Croatia started to develop more than 30 years ago in the form of non-bank card products, issued by American Express and Diners Club global payment systems. These card products were defined as standard charge cards and had been the only card products present in the market until bank cards appeared about ten years ago. The situation changed completely when banks started to enter the market as active participants in the card business. In co-operation with bank global payment systems, MasterCard Worldwide and Visa International, banks have issued several millions of various cards in just a few years, while non-bank issuers have followed the same trend with new card products. This paper explores the current situation in the domestic market; it determines who the cardholders of particular products are, which products they are familiar with, whether they use them or not and for what reason. Cardholders’ opinions, attitudes and preferences towards existing products have been explored, as well as the benefits they would like to get. The results obtained imply that cardholders are familiar with all bank and non-bank card brands, but that they use mostly those which provide them with specific benefits. Therefore, instead of focusing on providing more similar products, issuers should concentrate on designing differentiated products that have been tailored to cardholders’ real needs.

    Full Text Available Computer automatic understanding of document images becomes an increasingly hot issue in digital image processing and pattern recognition field, in which business card recognition system is a hot topic. The paper develops business card recognition software with good application prospects. It mainly has the functions including image acquisition, pretreatment, card recognition and extraction, business card tilt correction, positive and negative matching of business card, business card storage and retrieval. The paper proposes two new algorithms, one is to use digital image region labeling and automation for realizing automatic recognition and extraction of single business card, the other is to use pixel area interpolation method for tilt correction. The results prove that the two algorithms have wider applicability. They not only can use digital image region labeling and automation for form recognition, but also can use pixel area interpolation method for circumvolving in any angle.

    Full Text Available Credit institutions issuing and accepting cards have responsibility for identifying, evaluating and mitigation fraud and activities with potentially risk. Risk management is necessary to avoid losses that may occur both directly through fraud and indirectly through loss of customer confidence regarding safety card operations. The risk management in cards activities aims to identifying those events which by their appearance would produce adverse effects on the activity, possible generating financial loss and find solutions to avoid them and reduce their effect.Credit card fraud refers to any situation where a person deliberately uses: card obtained through illegal methods, a counterfeit card, a valid card code, in order to obtain cash, goods or undue services.

    Mayhew, David; Mitra, Robi D

    2016-02-01

    Calling card analysis is a high-throughput method for identifying the genomic binding sites of multiple transcription factors in a single experiment in budding yeast. By tagging a DNA-binding protein with a targeting domain that directs the insertion of the Ty5 retrotransposon, the genomic binding sites for that transcription factor are marked. The transposition locations are then identified en masse by Illumina sequencing. The calling card protocol allows for simultaneous analysis of multiple transcription factors. By cloning barcodes into the Ty5 transposon, it is possible to pair a unique barcode with every transcription factor in the experiment. The method presented here uses expression of transcription factors from their native loci; however, it can also be altered to measure binding sites of transcription factors overexpressed from a plasmid.

    Balanoiu, Paul

    2010-01-01

    Most developed countries have started the implementation of biometric electronic identification cards, especially passports. The European Union and the United States of America struggle to introduce and standardize these electronic documents. Due to the personal nature of the biometric elements used for the generation of these cards, privacy issues were raised on both sides of the Atlantic Ocean, leading to civilian protests and concerns. The lack of transparency from the public authorities responsible with the implementation of such identification systems, and the poor technological approaches chosen by these authorities, are the main reasons for the negative popularity of the new identification methods. The following article shows an approach that provides all the benefits of modern technological advances in the fields of biometrics and cryptography, without sacrificing the privacy of those that will be the beneficiaries of the new system.

    Scientists at the Relativistic Heavy Ion Collider (RHIC, BNL) recently discovered, that the hottest known form of matter is not a gas, but acts like a fluid. Furthermore, this fluid of quarks expands and flows much more perfectly than water or any other well known fluid. This aspect of the RHIC discovery can be introduced even to primary levels of physics education, noting that the usual solid to liquid to gas sequence of phase transitions now are known to be followed by a transition to a nearly perfect fluid, a liquid of quarks, at the largest temperatures made by humans. The educational games described herein were invented by middle school students, members of a Science Club in Hungary. The games were invented for their entertainment, the educational applications in teaching high energy particle and nuclear physics to laypersons are quite unexpected but most welcomed. This manuscript describes games with a deck of cards called Quark Matter cards, where each card represents an elementary particle. The games ...

    A system of car-sharing in Bremen, Germany, a membership-based structure of car-sharing that gives members access to a network of cars stationed throughout the city on a pay-per-trip basis, and without the hassles of car ownership, is discussed. The car-sharing scheme is combined with the city's transit system by means of a smart card that serves both as a pass for the city's transit system and as an electronic key to the cars in the car-sharing system. Future plans include to use the card also as a method of payment for taxis, and organizers are also working with the municipal government to get support for having car-sharing included in the city's official plan. At present, car-sharing stations are simply reserved parking spots for one or more cars, however, future stations are envisaged to include parking for up to five cars, a computer to book cars, direct access to keys using the smart card, parking for bicycles, and information about car-sharing stations, bus, trams, as well as bike and walking routes. Similar, if somewhat more modest, car-sharing schemes are also available in several cities in Canada, including Halifax, Quebec City, Montreal, Toronto, Calgary, Edmonton and Vancouver.

    We solve (3+1)--dimensional ideal hydrodynamical equations with source terms that describe punch-through and fully stopped jets in order to compare their final away-side angular correlations in a static medium. For fully stopped jets, the backreaction of the medium is described by a simple Bethe--Bloch-like model which leads to an explosive burst of energy and momentum (Bragg peak) close to the end of the jet's evolution through the medium. Surprisingly enough, we find that the medium's response and the corresponding away-side angular correlations are largely insensitive to whether the jet punches through or stops inside the medium. This result is also independent of whether momentum deposition is longitudinal (as generally occurs in pQCD energy loss models) or transverse (as the Bethe--Bloch formula implies). The existence of the diffusion wake is therefore shown to be universal to all scenarios where momentum as well as energy is deposited into the medium, which can readily be understood in ideal hydrodynam...

  19. Experimental studies on the punch shear characterization of satin weave graphite/epoxy composites at room and elevated temperatures

    International Nuclear Information System (INIS)

    In many situations, composite structures are subjected to dynamic loading. To design such structures, there is a need of dynamic material properties. In the current investigation, a compression split Hopkinson pressure bar (SHPB) was modified to load the samples in punch shear mode. Experimental studies were conducted to characterize 24-layer satin weave graphite/epoxy laminate samples. Laminates were manufactured using vacuum assisted resin infusion molding (VARIM) process. Samples of nominal size 26 mmx13 mmx4 mm were subjected to dynamic punch shear test at three different pressure settings that yielded strain rates in the range of 1500-3500 s-1 at room and elevated temperatures of 51.7, 79.4 and 107.2 deg. C. Dynamic shear stress-strain properties were evaluated. Failure modes were characterized through optical and scanning electron microscopy. Results of the tests indicate that the dynamic shear strength increases with increase with the strain rate and decreases with temperature for a given strain rate. Higher temperature causes the softening of matrix

    Nordholt, Jane Elizabeth; Hughes, Richard John; Newell, Raymond Thorson; Peterson, Charles Glen; Rosenberg, Danna; McCabe, Kevin Peter; Tyagi, Kush T; Dallman, Nicholas

    2015-04-07

    Techniques and tools for quantum key distribution ("QKD") between a quantum communication ("QC") card, base station and trusted authority are described herein. In example implementations, a QC card contains a miniaturized QC transmitter and couples with a base station. The base station provides a network connection with the trusted authority and can also provide electric power to the QC card. When coupled to the base station, after authentication by the trusted authority, the QC card acquires keys through QKD with a trusted authority. The keys can be used to set up secure communication, for authentication, for access control, or for other purposes. The QC card can be implemented as part of a smart phone or other mobile computing device, or the QC card can be used as a fillgun for distribution of the keys.

  5. Credit card spending limit and personal finance: system dynamics approach

    Full Text Available Credit cards have become one of the major ways for conducting cashless transactions. However, they have a long term impact on the well being of their owner through the debt generated by credit card usage. Credit card issuers approve high credit limits to credit card owners, thereby influencing their credit burden. A system dynamics model has been used to model behavior of a credit card owner in different scenarios according to the size of a credit limit. Experiments with the model demonstrated that a higher credit limit approved on the credit card decreases the budget available for spending in the long run. This is a contribution toward the evaluation of action for credit limit control based on their consequences.

    Jefferson Lab's Continuous Electron Beam Accelerator Facility (CEBAF) uses Trim Card I power supplies to drive approximately 1900 correction magnets. These trim cards have had a long and illustrious service record. However, some of the employed technology is now obsolete, making it difficult to maintain the system and retain adequate spares. The Trim Card II is being developed to act as a transparent replacement for its aging predecessor. A modular approach has been taken in its development to facilitate the substitution of sections for future improvements and maintenance. The resulting design has been divided into a motherboard and 7 daughter cards which has also allowed for parallel development. The Trim Card II utilizes modern technologies such as a Field Programmable Gate Array (FPGA) and a microprocessor to embed trim card controls and diagnostics. These reprogrammable devices also provide the versatility to incorporate future requirements.

    The role of payment cards in modern economies can hardly be underrated. In 2013, debit and credit card transactions represented roughly half of all consumer payment transactions in Western Europe, and accounted for more than 45% of all payment transactions in the United States. The payment card industry has faced intense antitrust scrutiny on both sides of the Atlantic, partly in response to the merchants’ recurrent complaints about high transaction fees.

  10. Why Do Debit Card Networks Charge Percentage Fees?

    OpenAIRE

    Price, David A; Wang, Zhu

    2013-01-01

    Why do debit card networks base their fees on a percentage of transaction amounts when the marginal cost of executing a transaction does not vary by amount? Research suggests that this type of fee structure, a linear ad valorem fee, maximizes profits for card networks by allowing price discrimination. Also, because percentage fees make card usage more economical for lower-value transactions, such a fee structure tends to increase social welfare.

    The aging of the electric production park implies an increasing need of knowledge concerning the evolution of the mechanical properties of its components. With regard to this problem, the availability in material is more and more small. This work proposes to characterize these properties through a mechanical test called Punch test. The main characteristic of this test is to use very small volume samples. The development of this test has been carried out by the study of a 15 MDV 4-05 steel coming from a steam drum of a thermal power plant after 145000 hours of service. At first, we have measured the influence of the parameters of this test. Then, the study has dealt more particularly on the transition temperature of the material. With the finite element simulation method, the strain hardening coefficient of the material has been determined. (O.M.)

Si esta es grave y se unen otros componentes, puede producirse caquexia cardíaca. Esta se asocia a mayor morbilidad y menor supervivencia de los pacientes que la padecen. Las causas de la caquexia cardíaca son diversas, en general asociadas a mantener balance energético negativo, surgiendo cada vez mayor evidencia que apoya un origen multifactorial de la misma. Entre otros, factores neurohormonales, inflamatorios, inmunológicos y metabólicos se superponen en el paciente con ICC, pudiendo producir afectación y deterioro de diversos órganos o sistemas, incluyendo la caquexia cardíaca. Esta puede definirse de diversos modos que, en general, concretan una reducción de peso en un tiempo definido o de estructuras corporales, ya que esta entidad afecta tanto a la masa magra o celular activa, como a los tejidos adiposo y óseo "osteoporosis. De todos ellos, el deterioro más acusado puede observarse en el tejido muscular esquelético, tanto a nivel estructural como funcional, no quedando exento el corazón de su afectación. Respecto del tratamiento, este debe basarse en la evidencia científica disponible. La valoración del estado nutricional de todo paciente con ICC es obligada, debiendo intervenir nutricionalmente ante MEP o riesgo de desarrollarla. En esta situación, mas si existe caquexia cardíaca, es necesaria una modificación de la dieta oral en energía y calidad de la misma, debiendo valorar la indicación de nutrición artificial específica complementaria o alternativa.

  17. Effects of grain size and specimen size on small punch test of type 316L austenitic stainless steel

    International Nuclear Information System (INIS)

    Miniature specimen test technique has been extensively studied for quantifying the properties of bulk materials. In this paper small punch test (SPT) is used to clarify the effects of specimen thickness (t), grain size (d) and ratio of thickness to grain size (t/d) on mechanical properties of 316L austenitic stainless steel (SS). Five sheet of 316L SS with the same texture but different thicknesses and grain sizes were prepared using rolling and heating treatment technique. Effective SPT yield strength was measured, and then used to correlate with conventional tensile test by empirical equation. The results show that the SPT is sensitive not only to differences in the thickness, but also to changes in the grain size and value of t/d. The present work provides information that enhance the understanding of reliability of SPT in analysis of the mechanical properties of small specimens and bulk materials. (author)

    2007-01-01

    the influence of splice joints on section forces and displacements are discussed considering the results from finite element calculations for a fink truss. It seems that the guidelines for treating splice joints as rotationally stiff do not necessarily lead to more realistic truss models.......The span of roof trusses with punched metal plate fasteners (nail plates) makes it often necessary to use splice joints in the top and bottom chords. In the finite element models used for design of the trusses these splice joints are normally assumed to be either rotationally stiff or pinned...... - their real behaviour is semi-rigid. The influence of splice joints on the distribution of member forces and rotations in the splice joints is investigated in this paper. A finite element program, TrussLab, where the splice joints are given semi-rigid properties is used to analyse the effect of splice...

  20. Comparison of mechanical properties in conventional and small punch tests of fractured anisotropic A350 alloy forging flange

    International Nuclear Information System (INIS)

    Conventional tensile test (CTT) and small punch test (SPT) was carried out on a failed ASTM A350 forging flange to study specimen size effect on mechanical behavior. Specimens were machined from the failed flange along Circumferential and longitudinal directions to study the effect of anisotropy on mechanical properties. Our results show that an optimum sampling has to be used for correlation between SPT and conventional tensile test (CTT). Fractography studies carried out on the failed samples indicate that the fracture modes of SPT samples and the CTT samples were different with the former showing better toughness than the latter. This is attributed to smaller size of the specimen and constraints imposed by the experimental setup. Due to the anisotropy of the forged material, the sampling plane in the SPT should be perpendicular to the load direction for reliable correlation between the results of both methods of testing.

    2011-12-01

    Full Text Available In modern retail market environment, electronic commerce has rapidly gained a lot of attention and alsoprovides instantaneous transactions. In electronic commerce, credit card has become the most importantmeans of payment due to fast development in information technology around the world. As the usage ofcredit card increases in the last decade, rate of fraudulent practices is also increasing every year.Existing fraud detection system may not be so much capable to reduce fraud transaction rate.Improvement in fraud detection practices has become essential to maintain existence of payment system.In this paper, we show how Hidden Markov Model (HMM is used to detect credit card fraud transactionwith low false alarm. An HMM based system is initially studied spending profile of the card holder andfollowed by checking an incoming transaction against spending behavior of the card holder, if it is notaccepted by our proposed HMM with sufficient probability, then it would be a fraudulent transaction.

  18. Vulnerabilities in First-Generation RFID-enabled Credit Cards

    Science.gov (United States)

    Heydt-Benjamin, Thomas S.; Bailey, Daniel V.; Fu, Kevin; Juels, Ari; O'Hare, Tom

    RFID-enabled credit cards are widely deployed in the United States and other countries, but no public study has thoroughly analyzed the mechanisms that provide both security and privacy. Using samples from a variety of RFID-enabled credit cards, our study observes that (1) the cardholder's name and often credit card number and expiration are leaked in plaintext to unauthenticated readers, (2) our homemade device costing around 150 effectively clones one type of skimmed cards thus providing a proof-of-concept implementation for the RF replay attack, (3) information revealed by the RFID transmission cross contaminates the security of RFID and non-RFID payment contexts, and (4) RFID-enabled credit cards are susceptible in various degrees to a range of other traditional RFID attacks such as skimming and relaying.

  19. Mobile Broadcast DRM Based on User Identity Card

    Directory of Open Access Journals (Sweden)

    Byung-Rae Lee

    2007-11-01

    Full Text Available The current mobile broadcast systems do not provide efficient solution for consumption of service and content based on the user identity card such as a smartcard. This prevents users from consuming broadcast service and contents independent of a specific terminal (e.g., the one used for registration or purchase. To provide usage of broadcast services based on the user identity card, mutual authentication needs to be established among the service provider, the terminal, and the user identity card whenever the terminal is changed. The crucial element for this is assuring the service provider, the terminal, and the user identity card by authenticating each entity to the other entities. In this paper, we propose the new authentication scheme, which provides efficient scheme for three kinds of mutual authentications among the service provider, the terminal, and the user identity card. We also construct mobile broadcast DRM system based on the proposed authentication scheme for consumption of broadcast services with multiple terminals.

  20. Anonymous Card Shuffling and its Applications to Parallel Mixnets

    CERN Document Server

    Goodrich, Michael T

    2012-01-01

    We study the question of how to shuffle $n$ cards when faced with an opponent who knows the initial position of all the cards {\\em and} can track every card when permuted, {\\em except} when one takes $K< n$ cards at a time and shuffles them in a private buffer "behind your back," which we call {\\em buffer shuffling}. The problem arises naturally in the context of parallel mixnet servers as well as other security applications. Our analysis is based on related analyses of load-balancing processes. We include extensions to variations that involve corrupted servers and adversarially injected messages, which correspond to an opponent who can peek at some shuffles in the buffer and who can mark some number of the cards. In addition, our analysis makes novel use of a sum-of-squares metric for anonymity, which leads to improved performance bounds for parallel mixnets and can also be used to bound well-known existing anonymity measures.
