Line-of-Sight MIMO in Point-to-Point Millimeter Wave Links via Scattering From Rough Surfaces
We analyze a point-to-point MIMO communication system over a deterministic channel with two paths: line-of-sight (LoS) and a scattered path over a rough surface.

A Novel Method for Estimating Free Space 3D Point-of-Regard Using Pupillary Reflex and Line-of-Sight Convergence Points [PDF]
In this paper, a novel 3D gaze estimation method for a wearable gaze tracking device is proposed. This method is based on the pupillary accommodation reflex of human vision. Firstly, a 3D gaze measurement model is built.

Cognitive factors that predict on-sight and red-point performance in sport climbing at youth level
IntroductionThe ascent of a route can be defined as being climbed on-sight or red-point. Climbing performance is measured by the grade of the personal best route that the athlete has ever climbed.MethodologyThe study examined 17 youth climbers (10 male ...

Lattice Point Visibility on Generalized Lines of Sight [PDF]
For a fixed $b\in\mathbb{N}=\{1,2,3,\ldots\}$ we say that a point $(r,s)$ in the integer lattice $\mathbb{Z} \times \mathbb{Z}$ is $b$-visible from the origin if it lies on the graph of a power function $f(x)=ax^b$ with $a\in\mathbb{Q}$ and no other integer lattice point lies on this curve (i.e., line of sight) between $(0,0)$ and $(r,s)$.

Psychological factors that influence performance in youth advanced climbers
Introduction: Rock climbing performance in lead can be measured in two ways: on-sight and red-point. On-sight climbing demands greater physiological and psychological factors. There are five main recurring themes that keep climbers highly motivated: risk

Target localization has been a popular research topic in recent years since it is the basis of all kinds of location-based applications. For GNSS-denied urban or indoor environments, the localization method based on time-of-arrival (TOA) is one of the ...

An Analysis of Sight Distances Considering Both the Vertical and Horizontal Curves of a Tourist Bound Destination Highway in Camarines Sur: The Lagonoy-Presentacion Section [PDF]
This analyzed sight distances contemplating both vertical and horizontal curves of a tourist bound destination highway in Camarines Sur, particularly the Lagonoy to Presentacion section. The Quantum Geographic Information System (QGIS) was used. The data

AimIn lead climbing, the ascent of the route can be defined as on-sight or red-point. On-sight is the more challenging style since it demands greater physiological and psychological commitment.

Preference at First Sight [PDF]
We consider decision-making and game scenarios in which an agent is limited by his/her computational ability to foresee all the available moves towards the future – that is, we study scenarios with short sight.

Improving the sampling strategy for point-to-point line-of-sight modelling in urban environments [PDF]
Visibility modelling calculates what an observer could theoretically see in the surrounding region based on a digital model of the landscape. In some cases it is not necessary, nor desirable, to compute the visibility of an entire region (i.e. a viewshed), but instead it is sufficient and more efficient to calculate the visibility from point-to-point ...
