Spectral Forecast equation for signals

open access: yes, 2022
One of the easiest applications to understand the spectral forecast equation is related to signals. A question that can be asked would be: given two signals A and B, what would a third signal M look like if it must resemble both signals in a certain ...

Researcher Identity in Transition: Signals to Identify and Manage Spheres of Activity in a Risk-Career

open access: yesFrontline Learning Research, 2015
Within the current higher education context, early career researchers (ECRs) face a ‘risk-career’ in which predictable, stable academic careers have become increasingly rare.

Design of ternary signals for MIMO identification in the presence of noise and nonlinear distortion [PDF]

open access: yes, 2009
A new approach to designing sets of ternary periodic signals with different periods for multi-input multi-output system identification is described. The signals are pseudo-random signals with uniform nonzero harmonics, generated from Galois field GF(q ...

Forty years on from the question of referential signals in nonhuman communication [PDF]

open access: yesAnimal Behavior and Cognition, 2020
In 1980, two groundbreaking articles were published by the team of Seyfarth, Cheney and Marler. In these papers, the question of whether vervet monkeys produced and encoded semantic information in their alarm calls set the stage for experimental ...

Awards as Signals [PDF]

open access: yesSSRN Electronic Journal, 2010
Awards are widespread in all countries and are prevalent both in the public sphere and in the private sector. This paper argues, and empirically supports, that awards serve public functions and economists should take them seriously. Using a unique cross-country data set, we suggest that awards serve as signals.

Statistical Distribution of EVM Measurements for Direct-Modulation Radio-Over-Fiber Links Transporting OFDM Signals [PDF]

open access: yes, 2013
The effect of distortion on the error vector magnitude (EVM) performance of orthogonal frequency-division multiplexing (OFDM) signals with different numbers of subcarriers and the connection to the peak-to-average power ratio (PAPR) of such signals is ...

The way ahead for London’s bus priority at traffic signals [PDF]

open access: yes, 2007
London has a long history of successful schemes for bus priority at traffic signals. Recently, Transport for London (TfL) has procured a modern automatic vehicle location (AVL) system for bus fleet management, passenger information and bus priority.

An Electro-Oculogram (EOG) Sensor’s Ability to Detect Driver Hypovigilance Using Machine Learning

open access: yesSensors, 2023
Driving safely is crucial to avoid death, injuries, or financial losses that can be sustained in an accident. Thus, a driver’s physical state should be monitored to prevent accidents, rather than vehicle-based or behavioral measurements, and provide ...
