We propose a new broadband beamformer design technique which produces an optimal receiver beam pattern for any set of field measurements in space and time. The modal subspace decomposition (MSD) technique is based on projecting a desired pattern into the subspace of patterns achievable by a particular set of space-time sampling positions. This projection is the optimal achievable pattern in the...

The teacher's gaze attention can trigger interaction with the student. So if teacher fails to equal during class, students may be alienated from interaction. According this perspective, study aimed establish pattern of science lecture classes and whether change when student's seat as an external factor changed. Eye tracking was conducted on six teachers fixation movement were also analyzed afte...

We present an analysis of a sequence of light curves of the RS CVn-type binary II Pegasi extending from 1974 to 1998. The distribution of the spotted area versus longitude is derived by Maximum Entropy and Tikhonov regularized maps, assuming a constant spot temperature (Lanza et al. 1998a). The spot pattern on the active K2 IV star can be subdivided into a component uniformly distributed in lon...

In modern digital agricultural applications, automatic identification and diagnosis of plant diseases using artificial intelligence is becoming popular widespread. Deep learning a promising tool in pattern recognition machine it can be used to identify classify paddy rice. this study, 2 different rice diseases, including blast brown spot, were investigated the district İpsala province Edirne be...

The macaque lateral geniculate nucleus (LGN) exhibits an intricate lamination pattern, which changes midway through the nucleus at a point coincident with small gaps due to the blind spot in the retina. We present a three-dimensional model of morphogenesis in which local cell interactions cause a wave of development of neuronal receptive fields to propagate through the nucleus and establish two...

Is there a significant difference between modelled and observed amplification of surface trends in the tropical troposphere

Low-loss spot size converters (SSC) are important elements for coupling photonic integrated circuits to fibres. We have developed a Cl2-based inductively-coupled-plasma process to etch non-selectively InP and photo-resist (PR). This process was then used to transfer a vertically-tapered PR pattern into an InP/InGaAsP structure. The tapered PR pattern was made using a standard optical lithograph...

We present here a pattern sensitive PowerPoint presentation scheme. The presentation is actuated by simple patterns drawn on the presentation screen by a laser pointer. A specific pattern corresponds to a particular command required to operate the presentation. Laser spot on the screen is captured by a RGB webcam with a red filter mounted, and its location is identified at the blue layer of eac...
