Detection of Unmanned Aerial Vehicles Using Computer Vision Methods: A Comparative Analysis

Pubblicato online: 09 Jul 2020
Pagine: 5 - 13

Astratto

Abstract

Detection of small objects in the airspace is a crucial task in the military. In the era of today’s unmanned aerial vehicles (UAVs) technology, many military units are exposed to recognition and observation through flying objects. They are often equipped with optoelectronic warhead making a way to collect essential and secret data of the military unit. Modern technical solutions make it possible to implement some methods facilitating detection of flying objects. A lot of them utilize computer vision techniques based on image processing algorithm. Therefore, in this article, we present an analysis of the most promising algorithm for detection of small flying objects.

Mechanical Properties of Welded Joints of 1.3964 Steel for Computer Aided Engineering (CAE) Purposes

Pubblicato online: 09 Jul 2020
Pagine: 15 - 28

Astratto

Abstract

The article presents the study of mechanical properties of welded steel from which the hull of a modern mine destroyer was made. Keeping the tightness of ship compartments during operation depends on the strength of these joints. The results of testing the mechanical properties of 1.3964 steel and its welded joints subjected to a static tensile test were presented, and a Johnson – Cook material model was proposed. The material model can be used in CAE (Computer Aided Engineering) simulations related to hull strength analysis.

Accessibility and Usability of Landsat 8 Data for the Purpose of Satellite-Drived Bathymetry of the South Baltic Near-Shore Waters on the Example of Gulf of Gdańsk

Pubblicato online: 09 Jul 2020
Pagine: 29 - 46

Astratto

Abstract

The paper presents the analysis of accessibility and usability of Landsat 8 Satellite Imagery for the purpose of Satellite Derived Bathymetry (SGB) products generation of the area of near-shore waters of the Polish coast. General assumptions of the SDB, Landsat program and factors affecting the products generation process have been described in details. Examples of SDB results, generated using both GIS software and Matlab, are presented on the example of chosen areas of Gulf of Gdańsk. The advantages and disadvantages of the SDB method are presented in the discussion and conclusion part with the proposed directions for the future works.

The Use of a Microcontrollers in Hygrometric Measurements Application

Pubblicato online: 09 Jul 2020
Pagine: 47 - 57

Astratto

Abstract

The article presents the possibility of using microcontroller systems as one of elements of a teaching position. The Arduino Mega system based on the ATMega 2560 microcontroller from the AVR family was used to build the station. At the beginning, a virtual hygrometer model was designed in the AUTOCAD program and then the air channels were made using 3D printing. After assembling the station, it was compared to a laboratory aspiration hygrometer. The analysis was presented in the final part of the article.

Modern Integrated Platform Management System Laboratory for Polish Naval Academy: Design and Implementation

Pubblicato online: 09 Jul 2020
Pagine: 59 - 71

Astratto

Abstract

This article contains a description of the implemented STANTOS™ Integrated Platform Management System (IPMS) laboratory created by Research and Development Center Maritime Technology Center for the Polish Naval Academy in Gdynia. The author briefly described the topology of the solution, justifies the choice of hardware and software solutions. Concept of use was written, where the usefulness of the implemented laboratory was motivated, with a focus on cases where safety plays a key role.

A Concept of BLDC Drive Model Containing Battery Cell Model

Pubblicato online: 09 Jul 2020
Pagine: 73 - 86

Astratto

Abstract

The paper presents a concept of overall BLDC drive model. Target model will be improved with a functional model of battery cell, which is commonly used as a power supply for the drive. The paper shows previous achievements in form of a functional BLDC motor model. Also, simulation results are presented. These are the partial results, that aimed to verify the basic model’s correctness as a basis of future developments. The procedure of power source selection presented in the article is vital to specify the technical parameters of modelled battery cell.
