2082   DISCUSSION OF SIGNALS WHICH CAN BE DERIVED FROM UNMODIFIED STANDARD AUTOMOTIVE ENGINE IGNITION SYSTEMS FOR TEST AND DIAGNOSIS PURPOSES. DISCUSSION OF SIGNALS WHICH CAN BE DERIVED FROM UNMODIFIED STANDARD AUTOMOTIVE ENGINE IGNITION SYSTEMS FOR TEST AND DIAGNOSIS PURPOSES.    1974 This paper discusses the use of the externally measurable high-voltage characteristics for deduction of both the operating condition of the ignition system and for deductions about compression, valve condition, and fuel mixture in the various cylinders. The paper also comments on the probable validity of each of these deductions. The second area described is the use of an ignition current measurement as opposed to a voltage measurement for the generation of the diagnostic indications. This is a ... 查看全文

2083   Towards the Experimental Assessment of NLBeam for Modeling Large Deformation Structural Dynamics Towards the Experimental Assessment of NLBeam for Modeling Large Deformation Structural Dynamics Sarah Dalton, Lisa Monahan, Ian Stevenson, D. J. Luscher, Gyuhae Park;Kevin Farinholt    0 With the growth of the wind energy industry, it has become apparent that gear boxes in wind turbines, which link the blades to the generator, tend to wear down faster than anticipated. This phenomenon is not clearly understood; one theory is that existing wind turbine modeling approaches used to design the turbines do not properly account for nonlinearities caused by large amplitude blade deformations. To help understand the effects of geometric nonlinearities, a... 查看全文

2084   The Limits of the Polygraph The Limits of the Polygraph    2003 The reliability and usefulness of the polygraph is discussed. For many in the US law enforcement and intelligence communities, polygraph has become the most valued method for identifying criminals, spies, and sabateurs when direct evidence is lacking. However, overconfidence in the polygraph, a belief in its ability that goes beyond that justified by evidence, presents a significant danger to achieving the objectives for which the polygraph is used. Thus, there is a need to be wary about the cla... 查看全文

2085   Tutorial on Experimental Dynamic Substructuring Using the Transmission Simulator Method Tutorial on Experimental Dynamic Substructuring Using the Transmission Simulator Method R;y L. Mayes    0 Although analytical substructures have been used successfully for years, practical experimental substructures have been limited to special cases until recently. Many of the historical practical applications were based on a single point attachment. Since substructures have to be connected, theoretically, in both translation and rotation degrees of freedom, measurement translation responses and forces around the single point attachment could be used to estimate the... 查看全文

2086   Experimental–Analytical Substructure Model Sensitivity Analysis for Cutting Machine Chatter Prediction Experimental–Analytical Substructure Model Sensitivity Analysis for Cutting Machine Chatter Prediction ;ers Liljerehn;Thomas Abrahamsson    0 Process reliability and dynamic stability is a growing customer demand in the metal machining industry. A limiting factor in process stability is regenerative vibrations which may damage the machined component, the cutting tool and even the machine tool. Spindle speed optimization to ensure process stability and enable larger cutting depths is based on the machine tool and cutting tool assembly’s frequency response at the tool-tip. The traditional procedure... 查看全文

2089   Compound‐lens injector for a pulsed 13‐TW electron beam Compound‐lens injector for a pulsed 13‐TW electron beam T. W. L. Sanford;J. W. Poukey;J. A. Halbleib;R. C. Mock    0 A robust injector capable of controlling the radius and angle of incidence of the pulsed, intense, annular electron beam extracted from the HERMES III accelerator is described. The injector, called the compound lens, uses a tapered anode to control the beam electrostatically, followed by a gas cell with externally applied current to control the beam magnetically. Adjustment of the anode‐cathode gap and external current of the injector permits the radius and angle to be defined independently of o 查看全文

2090   An Effective Method for Assembling Impulse Response Functions to Linear and Non-linear Finite Element Models An Effective Method for Assembling Impulse Response Functions to Linear and Non-linear Finite Element Models P. L. C. van der Valk;D. J. Rixen    0 The Impulse Based Substructuring (IBS) method has been proposed lately as an effective approach to evaluate the dynamic response of a system, using either the numerically or experimentally obtained Impulse Response Functions (IRFs) of its components. In this paper, the method will be combined with the (non-linear) Newmark time integration scheme in order to couple IRFs with linear and non-linear finite element models. In the linear case this is done by performing... 查看全文

2091   Developing a Finite Element Model in Conjunction with Modal Test for Wind Turbine Blade Models Developing a Finite Element Model in Conjunction with Modal Test for Wind Turbine Blade Models Eric Harvey, Peter Avitabile;Christopher Niezrecki    0 There are numerous modeling approaches that can be employed in the generation of composite models for wind turbine applications. Several more traditional approaches have been used over the past few decades. However, one modeling approach used for the generation of manufacturing models uses what is referred to as the unit cell approach. This modeling approach has been used for large deformation applications where the orientation realignment of the composite plies ... 查看全文

2096   Spectral Element Approximation of the Hodge-⋆ Operator in Curved Elements Spectral Element Approximation of the Hodge-⋆ Operator in Curved Elements Artur Palha;Marc Gerritsma    0 Mimetic approaches to the solution of partial differential equations (PDE’s) produce numerical schemes which are compatible with the structural properties – conservation of certain quantities and symmetries, for example – of the systems being modelled. Least Squares (LS) schemes offer many desirable properties, most notably the fact that they lead to symmetric positive definite algebraic systems, which represent an advantage in terms of computat... 查看全文

2097   Laboratory confirmation of congenital rubella syndrome in infants: An eye hospital based investigation Laboratory confirmation of congenital rubella syndrome in infants: An eye hospital based investigation James Hendrie, Luke Sammartino, Mervyn J Silvapulle and George Braitberg    2008 A total of 190 specimens from South Indian children aged 0–59 months with ocular anomalies consistent with suspected congenital rubella syndrome (CRS) were investigated. Twenty-six of the 65 infants (40%) were confirmed as CRS by detection of rubella specific IgM. Rubella RNA was detected in 41 samples from 26 infants by both real-time and block based PCR. The PCR results correlated well with the presence of anti-rubella IgM/IgG (23/27 cases with rubella IgM were PCR positive). Whereas, on... 查看全文

Antonov, Jacques Lefebvre and Jean-Louis Doublier    2011 An interpolymer complex was prepared by mixing aqueous solutions of poly(methacrylic acid) and hydroxyethylcellulose (molar substitution 2.5) and studied by using viscometric method. The hydrogen bonding is primarily involved in these complexations, but the hydrophobic interaction plays also an important role. The complex composition is not changing with the solvents used and is stable in the temperature range 25 °C - 65 °C. 查看全文
