We present a mobile fronthaul methodology for the analogue optical transmission of native radio signals with integrated photonic true-time delay beam steering phased-array antennas. Laser-based coherent homodyne detectors and dissemination through ultra-dense wavelength division multiplexing ensure low complexity at layer. experimentally demonstrate beamsteering linear antenna 1×3 configuration...

In this paper, we attempt to extend the definition and existing local error bound criteria to vector-valued functions, or more generally, to functions taking values in a normed linear space. Some new derivative-like objects (slopes and subdifferentials) are introduced and a general classification scheme of error bound criteria is presented.

We present two methods for lossy compression of normal vectors through quantization using “base” polyhedra. The first revisits subdivision-based quantization. The second uses fixed-precision barycentric coordinates. For both, we provide fast (de)compression algorithms and a rigorous upper bound on compression error. We discuss the effects of base polyhedra on the error bound and suggest polyhed...

This paper presents the analytical of non-Gaussian noise resistance with aid use bilateral in reverse confidential optical flow. In particular, flow is sample image’s motion from consecutive images caused by object’s movement. It a 2-D vector where every displacement displaying first image to second. When interferes flow, approximated performance on poor. We ensure greater appropriate applying ...

Model selection and associated issues of post-model selection inference present well known challenges in empirical econometric research. These modeling issues are manifest in all applied work but they are particularly acute in multivariate time series settings such as cointegrated systems where multiple interconnected decisions can materially a¤ect the form of the model and its interpretation. ...

The history of blood pressure (BP) waveform analysis is almost as undulatory as the waveform itself. The development of the sphygmograph in the mid-19th century led to a relatively brief, albeit intense, interest in the interpretation of the BP waveform. This was perhaps more an art than a science, and interest in the sphygmograph and the waveform declined after the introduction of the cuff-bas...
