Evaluation of the possibilities to use imagery reconnaissance sensors to identify the geological-engineering conditions in lowland river channels

Abstract

The article concerns the issue of using imagery reconnaissance sensors for the identification of geological-engineering conditions in river channels, in the aspect of evaluating the forcing of a water obstacle. It discusses the issues associated with using air platforms (manned and unmanned) in remote sensing surveying of selected fragments of the Vistula and Bug river channels and the correct interpretation of the obtained results, through their verification using bathymetric tests conducted directly in the river channels.

Western European Example of Defense Development

Abstract

It is particularly important for the French political leadership to maintain French independence, to develop military defense capabilities and to maintain a balance between budgetary constraints. The publication presents a European way of continuously modernizing the French army and modernizing its technical tools. France has one of the strongest and most powerful armed forces characterized by adapting NATO-based applications and procedures.

On a method for supporting visual identification of underwater objects

Abstract

The search and detection of objects under water is carried out by groups of specialised divers. However, their time underwater and their ability to penetrate the depths are limited. For these reasons, the use of unmanned underwater vehicles equipped with technical observation equipment, including TV cameras, is becoming increasingly popular for these tasks. Video images from cameras installed on vehicles are used to identify and classify underwater objects. The process of recognition and identification of objects is tedious and difficult and requires the analysis of numerous sequences of images, and so it is desirable to automate this process. In response to these needs, this article presents the concept of identification of underwater objects based on visual images from an underwater body of water sent from an unmanned underwater vehicle to a base vessel. The methods of initial processing of the observed images from an underwater area as well as the method of searching for selected objects in these images and their identification with the use of the Hough transform will be described. Furthermore, the paper presents the results of the preliminary processing and identification of the observed images following a deconvolution operation.

Research on the Dynamic Evolution Behavior of Group Loitering Air Vehicles

1 Introduction LAV (loitering air vehicles) is an advanced weapon system, which can loitering in the air over the targets area, detect and acknowledge the targets, and then attack them. It comes out with the development of UAV and munitions [ 1 ]. LAVs are being used for military tasks, such as reconnaissance, classification, electronic attack or as munitions in the battle [ 2 ]. The group LAVs has better ability to accomplishing the task than group independent LAVs through synergy. Through cooperation the team can reconfigure its distribution architecture

Les types de monopoles appartenant aux avocats et le rôle des directives de reconnaissance dans l’Union européenne et la Slovaquie

Summary

This article deals with the types of lawyers‘ monopoly and the related role of the EU recognition directives in the European Union and Slovakia. The European lawyers are benefiting mainly from the title and acts monopolies. The EU directives are influencing the monopoly architecture of European lawyers by creating the shared monopoly and the new title monopoly

Underground Facilities in Modern Conflicts

Abstract

Knowledge of the nature and location of underground facilities is of great value to both the urban attacker and defender. To exploit the advantages of underground facilities, a thorough reconnaissance is required. This papers describes the role of underground facilities in military actions in urban areas

The Quadrotor-Based Night Watchbird UAV System Used In The Force Protection Tasks

Abstract

The Unmanned Aerial Vehicles (UAV), or Unmanned Aerial Systems (UAS) are widely used today in real time, high precision reconnaissance missions. The UAS can lean on various types of the UAVs, whilst this paper deals only with multirotor UAV applications. The special flying abilities of the multirotor UAVs (e.g. vertical take-off and landing, hovering, flying at extremely low altitudes and airspeeds) open new areas in UAV applications. Challenges of the modern era put many problems to be solved such as problems of safeguarding in civil life, handling disaster management tasks, border control, and, finally, solution of force protection tasks in operational theatre, or out of war theatre. Author will lay down a brand-new concept of the UAV system applied in bad visibility to improve efficiency of the solution of the force protection tasks, which reduces human resources needed for this purpose. The proposed Night Watchbird UAV system is a new one using modern methods and principles to reach basic goal of reconnaissance providing real-time information for commanders, and for military forces, in general.
