Noise Abatement for Circular Saws

securitization of mortality risks in life annuities

insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...

Identification of critical speeds of clamped circular saws *

This paper presents a simple experimental methodology of determination of critical rotational speeds of circular saw blades. Both producers and users should be interested in getting information on the actual values of critical (permissible) speeds because very often rotational speeds recommended by producers (sometimes also marked on saw blades) are larger than the values obtained experimentally.

Improved Estimates of Kinematic Wave Parameters for Circular Channels

The momentum equation in the kinematic wave model is a power-law equation with two parameters. These parameters, which relate the discharge to the flow area, are commonly derived using Manning’s equation. In general, the values of these parameters depend on the flow depth except for some special cross sections. In this paper, improved estimates of the kinematic wave parameters for circular chan...
