This document provides a detailed discussion of the mathematical theory behind how the VSRT Interferometer works, and how it simulates a modern cross-correlation interferometer that professional radio astronomers use. This discussion, in general, is not intended for students. Instructors are advised to read this and decide for themselves whether their students would benefit from such a discussi...

Let d = (3 +1) 20 , where k is an odd integer. We show that the magnitude of the cross-correlation values of a ternary m-sequence {st} of period 3 − 1 and its decimated sequence {sdt} is upper bounded by 5 √ 3n + 1, where n = 4k.

In this paper, we investigate prosodic alignment in task-based conversations. We use the HCRC Map Task Corpus and investigate how familiarity affects prosodic alignment and how task success is related to prosodic alignment. A variety of existing alignment measures is used and applied to our data. In particular, a windowed cross-correlation procedure, that has been used previously in visual beha...

We describe a corpus-based approach to improving synthesized speech quality and present two useful cost functions for unit selection. One is pitch-synchronous cross correlation for concatenation costs to reduce the noise caused by phase mismatch at concatenation points. The other is a discontinuous cost function for internal and concatenation costs to eliminate unnecessary cost calculation. An ...

In this paper, we introduce a novel algorithm to solve the problem of object tracking across multiple nonoverlapping cameras by learning inter-camera transfer models. The transfer models are divided into two parts according to different kinds of cues, i.e. spatio-temporal cues and appearance cues. To learn spatiotemporal transfer models across cameras, an unsupervised topology recovering approa...

In this paper, we investigate the properties of generalized bent functions defined on Z2 with values in Zq , where q ≥ 2 is any positive integer. We characterize the class of generalized bent functions symmetric with respect to two variables, provide analogues of Maiorana–McFarland type bent functions and Dillon’s functions in the generalized set up. A class of bent functions called generalized...

Two particle azimuthal correlation functions are presented for charged hadrons produced in Au + Au collisions at RHIC (√ s NN = 200 GeV). The correlation functions indicate sizeable asymmetries and anisotropies. The trend of the asymmetries is compatible with the presence of emission patterns associated with mini-jets. The magnitude and the trend of the differential anisotropies v 2 (p T) and v...

Monitoring a communication line is significant for broadband, mobile phone and so on. In this paper, we propose a new method for detecting a fault point of communication line by use of M-sequence correlation technique. In this method, detecting signal is used as one or plural M-sequences ( same characteristic polynomial, including normal and reverse mark, synchronized ). At receiving tap, we ma...

Many studies have presented stress-strain relationship of human hair, but most of them have been based on an engineering stress-strain curve, which is not a true representation of stress-strain behaviour. In this study, a more accurate 'true' stress-strain curve of human hair was determined by applying optical techniques to the images of the hair deformed under tension. This was achieved by app...
