A practical method of designing active filters in which the transfer function is independent of both firstand second-order operational amplifier time constant effects is presented. Neither matched operational amplifiers nor a tuning procedure dependent on an active parameter is required. The active portion of these filters is universal and readily integrable since it is comprised of conventiona...
Operational modal analysis deals with the estimation of modal parameters using vibration data obtained from unknown or ambient excitation sources in operational rather than laboratory conditions. The paper compares three operational modal parameter identification approaches for identifying modal parameters of a multi-span concrete motorway bridge when subjected to either ambient or broad-band l...
Dye photodegradation using ozone and Nickel ferrite nanoparticle (NFN) as a photocatalyst was studied. The catalyst was synthesized and characterized by FT-IR, SEM and XRD. Textile dyes including Remazol Red RB (RRRB) and Direct Green B (DGB) were degraded as model compounds. Dye degradation was investigated using UV–Vis and ion chromatography (IC) analyses. The effect of catalyst dosage, pH, s...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
This memo describes the management and operational requirements for the address and routing parameter area ("arpa") domain. The "arpa" domain is used to support a class of infrastructural identifier spaces, providing a distributed database that translates elements of a structured name space derived from a protocol family to service names. The efficient and reliable operation of this DNS space i...
Biological systems can possess multiple operational modes with specific nonlinear dynamics in each mode. Hybrid automata and its variants are often used to model and analyze the dynamics of such systems. Highly nonlinear hybrid automata are difficult to analysis and usually have many parameters. An important problem is to identify parameter values using which the system can reach certain states...
Two different coarse alignment algorithms for Fiber Optic Gyro (FOG) Inertial Navigation System (INS) based on inertial reference frame are discussed in this paper. Both of them are based on gravity vector integration, therefore, the performance of these algorithms is determined by integration time. In previous works, integration time is selected by experience. In order to give a criterion for ...
Electron beam welding (EBW) shows certain problems with the control of focus regime. The electron beam focus can be controlled in electron-beam welding based on the parameters of a secondary signal. In this case, the parameters like secondary emissions and focus coil current have extreme relationships. There are two values of focus coil current which provide equal value signal parameters. There...
Soil moisture is a key parameter in different environmental applications, suchas hydrology and natural risk assessment. In this paper, surface soil moisture mappingwas carried out over a basin in France using satellite synthetic aperture radar (SAR)images acquired in 2006 and 2007 by C-band (5.3 GHz) sensors. The comparisonbetween soil moisture estimated from SAR data and in situ measurements s...
