Do Explicit Estimates of Angular Declination Become Ungrounded in the Presence of a Ground Plane?

open access: yesi-Perception, 2018
In a series of seven experiments (total N  = 220), it is shown that explicit angular declination judgments are influenced by the presence of a ground plane in the background. This is of theoretical importance because it bears on the interpretation of the

Design of a Low-SLL SIW Slot Array Antenna With a Large Declination in $Ka$ -Band

open access: yesIEEE Access, 2019
A small-size large-declination longitudinal slot array antenna based on substrate integrated waveguide (SIW) technology was proposed. Compared with the conventional SIW slot array, the proposed antenna achieves a larger declination and a lower SLL.

Secular variations of geomagnetic declination in the Karadag point and the global helio-geodynamic processes

open access: yesГеофизический журнал, 2019
To study the changes in the local variations of geomagnetic field, the Karadag point was chosen due to the fact that we found previously on increased insolation and the surface temperature of the earth at this point over the last century (compared to ...

Determination of the Declination of the Sun on a Given Day [PDF]

open access: yes, 2012
In this article we discuss a novel and low cost experiment to determine the angle of declination of the sun on a chosen day. The declination of the sun varies from + 23.5 degrees to - 23.5 degrees in the course of one year.

Decline increasing: normality declining [PDF]

open access: yesPhysics World, 1998
Information is the currency of scientific pursuit, and its immediate access is a presumed universal right to today's students. No longer must the information-seeker spend hours, days and even weeks trawling through Current Contents, as all information is now freely available at the click of a mouse.

Open-Source Carbon Footprint Estimator: Development and University Declination

open access: yes, 2021
Anthropogenic greenhouse gas emissions need to be cut to limit climate change. Thus, universities, in the same way as citizens and companies, are starting to raise awareness about this issue and to take action to reduce their carbon footprint.
