Determination of particulate absorption in natural waters is often made by measuring the transmittance of samples on glass-fiber filters with the so-called quantitative filter technique (QFT). The accuracy of this technique is limited due to variations in the optical properties of the sample/filter composite, and due to uncertainties in the path-length amplification induced by multiple scatteri...

This paper discusses the robust model-based fault detection filter design problem for faults in the air path of diesel engines. Two failure modes in the air path, namely, the Exhaust Gas Recirculation (EGR-Actuator) and Variable Geometry Turbocharger (VGT-Actuator) bias faults were considered. The objective of the design is the detection of failures, which is robust against model uncertainties ...

This paper presents a precise analysis of the criticalpath of the least mean square ( LMS) adaptive filter for deriving itsarchitectures for high speed and lowcomplexityimplementation.It is shown that the direct-form LMS adaptive filter has nearly thesame critical path as its transpose-form counterpart, but providesmuch faster convergence and lower register complexity. From thecritical-path eva...

A system that enables continuous slip compensation for a Mars rover has been designed, implemented, and field-tested. This system is composed of several components that allow the rover to accurately and continuously follow a designated path, compensate for slippage, and reach intended goals in high-slip environments. These components include: visual odometry, vehicle kinematics, a Kalman filter...

In this paper a modified version of the Akthar’s method for online secondary path modeling in active noise control systems is proposed. The proposed method defines two variable step sizes for control filter and modeling filter. The control filter step size μm is adapted by using the variable threshold value Tj and the modeling filter step size μm is adapted by using a new modified variable step...

The article applies a new approach to microminiaturization of the VHF radio path with significant improvement its main characteristics based on acoustoelectronic elements SAW. In particular, instead intermediate frequency filter (IF), which in most cases is implemented help "coil " products (LC circuits), CSF (concentrated selection filter) proposed be characteristic curve, and same traditional...

Reverses of the Schwarz, triangle and Bessel inequalities in inner product spaces that improve some earlier results are pointed out. They are applied to obtain new Grüss type inequalities. Some natural integral inequalities are also stated.

Some inequalities in 2-inner product spaces generalizing Bessel’s result that are similar to the Boas-Bellman inequality from inner product spaces, are given. Applications for determinantal integral inequalities are also provided.

This paper shows that the plane wave expansion can be a useful tool in obtaining analytical solutions to infinite integrals over spherical Bessel functions and the derivation of identites for these functions. The integrals are often used in nuclear scattering calculations, where an analytical result can provide an insight into the reaction mechanism. A technique is developed whereby an integral...

New reverses of the Schwarz, triangle and Bessel inequalities in inner product spaces are pointed out. These results complement the recent ones obtained by the author in the earlier paper [13]. Further, they are employed to establish new Grüss type inequalities. Finally, some natural integral inequalities are stated as well.
