Abstract:

Licensed mariners carried out two simulated navigation studies testing electronic chart and information display systems (ECDIS) against paper chart navigation. In the first study, six mariners each completed approaches to Halifax, Nova Scotia, harbour with good and bad visibility and a range of wind and currents. Conditions included chart with radar, ECDIS with radar overlay and ECDIS with separate radar. ECDIS produced better performance and a smaller workload than paper charts and the radar overlay was slightly better than the separate radar display. In the second study, six new mariners com

Abstract:

While radar charts are widely used for visualizing multivariate data across various fields, and mobile technology enables screen refresh for potentially enhanced viewing experiences, the impact of chart design and user interaction on visual perception remains largely unexplored. This study investigates the effects of radial axes, data series, and screen refresh on perceptual bias in mobile radar chart visualization. An experiment with 157 participants revealed non-significant main effects for all three factors but significant interactions between data series and both radial axes and screen ref

This paper is determined to relation between equilibrium and how the radar chart plots equilibrium. Now why equilibrium? The concept behind equilibrium is to control ageing in humans so that the span of life increases. This is a mathematical expression of how ageing would be controlled in terms of radar charts. I hope this paper serves as a first step towards decoding immortality mathematically. I do not consider this attempt of mine insane. Nothing is impossible or abstract.

This work presents a diagraph method for the description and predication of the potential machinability of work materials. In the method, a radar chart with five axes was used to examine the machinability of different work materials and each axis representing a behavior or property, i.e. abrasiveness or hardness of workpiece material by grading the 5 different machinability properties. Such charts are seen to be helpful in the setup work to machine the new materials or unknown materials when choosing suitable tool properties and the cutting data suitable for the new material machining.

Abstract. Distortions are often seen in the angular distribution of echo-power from VHF wind-profiling radars, suggesting that thin stable layers, within the air flow, are distorted and tilted from horizontal. In vertical shear of the horizontal wind, the distribution of the layer tilt angles becomes skewed. A case study using six days of VHF radar data and synoptic charts above western Europe indicates that this asymmetry of atmospheric microstructure can exist throughout the troposphere and lower stratosphere, above and below the jet wind maximum, over horizontal scales of thousands of kilom

Approximately 1000 Canadian Hydrographic Service (CHS) charts cover Canada’s oceans and navigable waters. Many charts use information collected with techniques that predate the more advanced technologies available to Hydrographic Offices (HOs) today.

Abstract:

The approaches to the cognitive modelling of education system as a complex system of modular architecture with the corresponding system attributes are defined. The modular hierarchical structure of educational system itself is based on the hierarchical structure of the set of particular criteria. The methodological principles for assessing the quality of the educational system are indicated. It is emphasised that measuring of indicator changes the system itself, thus making control ineffective. The insufficient performance of educational institutions' evaluation on the basis of radar chart is

Abstract:

The prevailing technology for pedestrian recognition in unmanned driving, predominantly reliant on LiDAR, confronts the dual challenges of elevated expenses and limited anti-interference capabilities. To surmount these obstacles, this paper introduces an inventive fusion methodology that harmonizes inputs from visual cameras, 4D millimeter wave radar, and thermal imaging sensors. The advantages and promising development prospects of 4D millimeter wave radar over laser radar are comprehensively elucidated. By leveraging advanced signal processing algorithms, a robust mathematical model is formu

Abstract. Geographical Information Systems (GIS) can be used to integrate data from different sources and in different formats to perform innovative spatial and temporal analysis. GIS can be also applied for climatic research to manage, investigate and display all kinds of weather data. The main objective of this study is to demonstrate that GIS is a useful tool to examine and visualise precipitation distribution obtained from different data sources: ground measurements, satellite and radar data. Three selected days (30 cases) with convective rainfall situations were analysed. Firstly, scalabl

Abstract:

Abstract. Satellite radar altimeters provide crucial insights into polar oceans and their sea ice cover, enabling the estimation of sea level, sea ice freeboard, and thickness. These retrieval algorithms depend on accurate discrimination between radar altimeter waveforms from sea ice and ocean surfaces in heterogeneous and dynamic surface conditions. A further and less mature step is classifying different sea ice types in addition to the ice/ocean discrimination. We aim to develop new methods for a novel multi-category sea ice and ocean surface classification directly from satellite radar alti
