A Study of Shock Analysis Using the Finite Element Method Verified with Euler-Bernoulli Beam Theory; Mechanical Effects Due to Pulse Width Variation of Shock Inputs; and Evaluation of Shock Response of a Mixed Flow Fan
… Beam Theory; Mechanical Effects Due To Pulse Width Variation Of Shock Inputs; And Evaluation Of Shock Response Of A Mixed Flow Fan</p> <p>David Jonathan González Campos</p> <p>For many engineers that use finite element analysis or FEA, it is very important to know how to properly model and …

Numerical modeling of river migration incorporating erosional and depositional bank processes
… In almost all these models however, a river width that remains constant in space and in time is imposed as a user-specified parameter, without any consideration of the processes that establish this width. Consistent width variation patterns found in most meandering rivers are largely ignored …

Long Waves In Channels Of Non-Uniform Cross-Section
… changes slowly and channels where the depth and width variation is appreciable within the wavelength scale are discussed to illustrate the scope of applicability of the present theory. By considering viscous boundary layer effects, the theory agrees well with experimental results for converging …

Design of quantum well infrared photodetectors
… (HRXRD) was used to measure the layer width variations of QWIPs grown by molecular beam epitaxy. The spread of the measured full-width-half-maxima of superlattice diffraction peaks with the diffraction order was used with Bragg's Law to obtain the measured layer width variation in the …

Genic identity and differentiation of Ilyodon (Cyprinodontoidea: goodeidae): morphological polymorphism and chromosomal divergence
… localities and conspecificity of two mouth width morphs. Progeny of field inseminated females yielded some offspring with morphs opposite to those of their mother and some progeny of laboratory crosses were of morphs different from their parents. The analysis of Ilyodon broods conclusively …

Geometrical control of domain walls and the study of domain wall properties of materials with perpendicular magnetic anisotropy
… on an undercut resist profile and wire width variation from the patterning process would affect DW behavior, including static configurations, stability and dynamics under current pulsing. I will then discuss how similar geometrical effects will affect the properties of materials with …

High Speed Acoustophoresis for Multiphase Micron-Sized Particle Assembly
… sensitive to sound speed, where 1% sound speed variation leads to a 4% change in the assembly time. Examination of the acoustophoresis standing waves show that sound speed and vessel width variation contribute to imperfect constructive interference of the standing waves, further reducing …

pinMOS Memory
… existence of quasi steady-states as well as the width variation of space charge zones. The pinMOS memory shows excellent repeatability, an endurance of more than 104 write-read-erase-read cycles, and currently already over 24 h retention time. Furthermore, an early-stage investigation on …

Probes of pulsar emission physics: The double pulsar and the gamma-ray pulsar population
… By fitting for the observed pulse profile widths, the model constrains the geometry angles of pulsar B, namely the magnetic misalignment from the spin axis alphaB = 61 deg and the spin misalignment from the orbit normal thetaB = 138.5 deg, which are consistent with and similar to those …

Long-term morphological response of tide dominated estuaries
… by a funnel-shaped geometry with a high width-to-depth ratio. The width of the estuarine section tends to decrease rapidly upstream, following an exponential law and the bottom slopes are generally non-significant. In this thesis the long-term morphological evolution of tide-dominated …
