Due to extraordinarily high investment, many technical issues yet to be solved and limited experience, the risk of building offshore wind power generation system is always very high. The study presented in this paper takes a view of the effect of offshore wind

The face and the ear are highly attractive biometric traits for combination because of their physiological structure and location. Besides, both of them can be acquired non-intrusively. However, changes of facial expressions, variations in pose, scale and illumination and the presence of hair and ornaments present some genuine challenges. In this paper, a 3D local feature based approach is proposed to fuse ear and face biometrics at the score level. Experiments with F RGC v.2 and the University of Notre Dame Biometric databases show that the technique achieves an identification rate of 98.71% and a verification rate of 99.68% (at 0.001 FAR) for fusion of the ear with neutral face biometrics. It is also found to be fast and robust to facial expressions achieving 98.1% and 96.83% identification and verification rates respectively.

But accurate and rapid detection of the ear for real-time applications is a challenging task, particularly in the presence of occlusions. In this work, a cascaded AdaBoost based ear detection approach is proposed. In an experiment with a test set of 203 profile face images, all the ears were accurately detected by the proposed detector with a very low (5 × 10 −6 ) false positive rate. It is also very fast and relatively robust to the presence of occlusions and degradation of the ear images (e.g. motion blur). The detection process is fully automatic and does not require any manual intervention.

The identification of the various isomers of these complexes is also reported. The various isomers are separated from their mixture by fractional crystallization. Each of these complexes has been characterized by observing physical characteristics, chemical analysis, UV-visible spectroscopy and IR-spectroscopy. The direct impact of geometry of the complexes to IR stretching frequencies and UV-visible spectral data of amino and carboxyl group in the complexes provided sufficient information about the geometry. A prediction about the geometries of the synthesized has also been focused.

MTDTS consists of a client station (operator) and a server station (slave arm) interconnected by a computer network. MTDTS is evaluated using a set of tele- operated experiments which are (1) peg-in-hole insertion, (2) assembly of a small water pump, (3) operating drawers, (4) pouring of water, and (5) wire-wrapping. Direct teleoperation

Instead of conventional fuzzy logic or Galois Field theory, the logic system is based on the extension of Boolean algebra. The logic is capable of handling both quaternary and coupled-binary inputs, where binary operands are coupled in pairs to form quaternary entities. All necessary operators are defined and several theorems and

Transfer function analysis offers the additional advantage of fault identification and location. High frequency resonance in a transformer can be modeled by analogue distributed winding concepts. Every transformer has an unique transfer function independent of the shape of the input
