On the shock performance of a nonlinear vibration isolator with high-static-low-dynamic-stiffness
(Elsevier B.V., 2014-04-01)
The vibration isolation characteristics of a high-static-low-dynamic-stiffness (HSLDS) isolator, which has geometrically nonlinear stiffness, have been well established both theoretically and experimentally in the recent ...
Using nonlinear jumps to estimate cubic stiffness nonlinearity: An experimental study
(2016-12-01)
Attempts are being made to improve mechanical design by using nonlinearity rather than eliminating it, especially in the area of vibration control and in energy harvesting. In such systems, there is a need to both predict ...
Programmable multichannel sine wave generator for a C-MEMS based dielectrophoretic filter
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2008-12-01)
This thesis develops a programmable multichannel sine wave generator for a CMEMS dielectrophoretic filter in order to separate bio-particles.
Independent frequency generation is obtained using the direct digital frequency ...

Quantitative proteomic and transcriptional analyses reveal degradation pathway of γ- hexachlorocyclohexane and the metabolic context in the actinobacterium Streptomyces sp. M7
(Pergamon-Elsevier Science Ltd, 2018-07)
Highly γ-hexachlorocyclohexane (lindane) contaminated areaswere reported worldwide. Low aqueous solubility and high hydrophobicitymake lindane particularly resistant to microbial degradation.Physiological and genetic ...
Estudo e comparação de métodos de identificação de sistemas dinâmicos
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2016-06-16)
This work presents a comparative study between some identification methods for dynamical systems. For systems characterization, different signals are applied, such as step function, sine and square waves. Four graphical ...
The Interface between Extracellular and Transmembrane Domains of Homomeric Cys-Loop Receptors Governs Open-Channel Lifetime and Rate of Desensitization
(Society for Neuroscience, 2008-07)
The lifetimes of activated postsynaptic receptor channels contribute to the efficiency of synaptic transmission. Here we show that structural differences within the interface dividing extracellular and transmembrane domains ...
