A method of characterisation of the nonlinear vibration transmissibility of cushioning materials
… this is achieved by the measurement of the transmissibility or Frequency Response Function (FRF) of the product/cushion system by a Single Input-Single Output (SISO) approach assuming a linear relationship. However, the product/cushion system can exhibit strong nonlinear behaviour. The …

Isolation and transmissibility of shipboard equipment with carbon fiber reinforced polymer mount
The isolation and transmissibility of shipboard equipment is important to the function of a ship. The transmission of vibration from an engine to its surroundings can be devastating to sensitive equipment and disrupt normal operations. Isolator pads can be used to dampen transmissions from …

The Molecular Basis of Fitness and Transmissibility of Neuraminidase Inhibitor Resistant Influenza A Viruses
… there was an urgent need to characterize the transmissibility and fitness of oseltamivir-resistant pandemic H1N1/2009 viruses, although the resistance rates have remained low so far.</p> <p>We first addressed the urgent question about pandemic viruses by investigating the transmissibility of a …

Investigation of issues related to the revision of ISO 10819
… the effect of palm adapter geometry on linear transmissibility and mean corrected transmissibility values. Finally, the effect of test subject training is discussed and supporting data is shown; 30 rigid acrylic adapters were designed, fabricated, and tested. All adapters fell into one of four …

Analysis of an Anti-vibration Glove for Vibration Suppression of a Steering Wheel
… system. The model is validated by comparing transmissibility obtained numerically to transmissibility obtained from experiments. The resulting governing equations of motion are solved analytically using the method of undetermined coefficients. Parametric analysis is performed on the …

Two Dimensional Analysis of Vibration Isolation of Rigid Bar Supported by Buckled or Pre-bent Struts
… vibrations, determining the displacement transmissibility of the system is the main goal of this research. Transmissibility versus frequency plots are generated for all cases, with varying parameters such as stiffness, damping, and location of center of mass, to determine how they affect …

Strains of Soybean Mosaic Virus: Aphid Transmission, Host Passage Effects, and Use in Evaluation of Genetic Resistance in Soybeans
… however, one isolate of strain G5 lost its aphid transmissibility after about 30 successive passages by sap inoculation through a susceptible soybean cultivar Rampage during 20 months. The aphid nontransmissible strain G5 (designated NG5) was used to study the mechanism of aphid …

Factors affecting the dynamic response of the body and the vibration transmitted through seats
… that the apparent mass of the body and seat<br/>transmissibility are affected by the seating environment (e.g. vibration input spectra, backrest,<br/>hands position, foot position) and variability between people (i.e. physical characteristics), but<br/>these effects have not previously been …

Pinning control of disease networks
… by first estimating the reference average transmissibility from the statistical physics technique known as bond percolation. Once the average transmissibility is known, node-, network- and population mass-action models can be measured for incidence. Two selective pinning control strategies, …

Vibration Isolation of a Horizontal Rigid Plate Supported by Pre-bent Struts
… in the configuration described. The displacement transmissibility will be the measure of the isolators' effectiveness at mitigating vibrations transmitted from the base to the rigid plate. For each case, the nonlinear equilibrium equations and the governing equations of motion for small vibrations …

Modeling, Analysis and Testing of a Semi-Active Control System for Landing Gear Applications
… data, was used to predict the improvement in transmissibility resulting from these modifications. The results indicate that controllable dampers using a ‘no jerk' skyhook control policy can reduce transmissibility of ground input to the fuselage.</p>

International Externalities in Pandemic Influenza Mitigation
… Under the base case assumptions of moderate transmissibility of the flu, the distribution of antiviral stockpiles from rich countries to poor and lower middle income countries may indeed pay for itself: providing a stockpile equal to 1% of the population of poor countries will reduce cases in …

Evaluation of Anti-Vibration Gloves in a Manufacturing Setting
… samples was found for each glove to find the transmissibility factor. The gloved transmissibility factors were then compared to that subject's bare hand sample to find the corrected transmissibility of the glove. The results differed depending on which surface was used. On the horizontal …

Geographic and demographic transmission patterns of the 2009 A/H1N1 influenza pandemic in the United States
… mixing in schools. Geographic variation in transmissibility is explored further by nesting a latent Gaussian process within the mechanistic transmission model, revealing a possible region of elevated transmissibility in the south-eastern US. Then, using the mechanistic model and a …

Preliminary investigation of the vibration characteristics of a slip table
… and experimentally. This ratio is called the transmissibility. Experimental results were good under certain conditions, but tended to have increasingly larger errors as frequencies increased.

Pandemic Potential of Reassortant Swine Influenza A Viruses
… reassortant swine influenza A viruses, their transmissibility, and their relative fitness compared to classical and double reassortant swine influenza viruses. Several triple reassortant viruses, including one with avian-origin HA and NA, were characterized in the ferret, which is a commonly …

Extraction methods for multidirectional driving point accelerance and transfer point accelerance matrices
… rocking motion leads to incorrect bare vehicle transmissibility matrix and incorrect global transmissibility matrix. The driving point difference error increases quickly as the distance between the impact and measurement points increases;The DOF deficiency error has several sources. It comes …
