We propose a hybrid option for the first local oscillators (LOs) of ALMA in which a direct photonic LO driver is used to drive cold multipliers. The photomixer using NTT uni-travelling carrier photodiode has been demonstrated to have high power of 2 m W at 100 GHz and low amplitude noise of < 7 − 17 K/μW in the frequency range of 98 − 105 GHz. This option simplifies the LO part of the cartridge...

This paper purposes a new method for selecting the most discriminant rotation invariant patterns in local binary patterns and local ternary patterns. Our experiments show that a selection based on variance performs better than the recently proposed method of using dominant local binary patterns (DLBP). Our method uses a random subspace of patterns with higher variance. Features are transformed ...

points z z The UK system of government is one of the most centralized in the developed world. As a result, local governments have very few powers when it comes to tax regulation, while their policy choices are constrained by tightly controlled expenditure mandates. z z Nevertheless, there is evidence that local party control does matter. A switch from Conservative to Labour Party control usuall...

Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...

with the development of deregulated power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benefi...
