Both concepts were implemented into the Czech Armed Forces and adapted to fit their ambitions, possibilities, tasks and specific goals. The primary goal of this adoption was to achieve the capabilities to work in a coalition environment. The experiences from Intelligence, Surveillance, and Reconnaissance integration projects are presented in the second part of the article. After assessing the current state, development goals are characterized as challenges that need to be addressed with a solution that is described.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48279053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additional nonlinearity and coupling result when the aircraft attempts some supermanoeuvres under such conditions rendering nonlinear control implementation unavoidable. However, such controls depend on accurate onboard c.g information. The present paper proposes a novel neural network aided sliding mode based hybrid control scheme which does not require such an information. The neural controller is trained offline to compensate for the changed dynamics arising from the lateral mass asymmetry, while the sliding controller is designed for the intended manoeuvres under the nominal situation. Cobra and Herbst manoeuvres are simulated for various lateral c.g. movements to validate the scheme.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41378381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The preliminary credibility assessment screening system (PCASS) assisted to provide initial screening of suspects for further follow up of intelligence and security forces. Thus, the objective of this article is to explore the dynamics of employing this technology in fragile states in support of the intelligence activities. To that purpose, we have used an exploratory case study research, which included several sources of data collection. We found that PCASS is used to empower the Afghan police forces to identify and neutralize insider threats, but also to keep NATO-coalition forces safer. Further research should focus, for instance, on the impact of the Afghan culture on PCASS operations.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41298655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Torpedo Defence System (TDS) is an essential fitment on modern high value platforms. Timely detection and identification of a torpedo attack is the primary function of a TDS. Localisation and countermeasures against the weapon are the next stage in torpedo defence. Detection of modern torpedoes with long endurance can only be achieved using an underwater sensor suit with wide frequency coverage. Tactical use of multiple counter measures is essential for evading an attacking torpedo with intelligent homing mechanism. Individual sensors and counter measures are no longer considered as a solution; they are rather considered as components of a large network of systems to protect the platform from torpedo attack. A System of Systems (SOS) architecture with multiple sensors, processing techniques, countermeasures and tactics are presented in this paper for achieving fail-safe torpedo defence capability.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43478962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current approach of the extreme hierarchical command and control cannot be sustained in this complex and dynamic environment. Thus, making the search for new command and control approaches is a critical activity. The description and classification of command and control approaches is expressed in a very abstract way. The article describes a unique, quantification technique of command and control approaches. The quantification is demonstrated by Use Case with self-synchronization as the selected command and control approach. In the Use Case, the deterministic dynamic model is implemented. The results achieved from the model demonstrate a variance of a single parameter, on which the quality of the selected Command and Control approach in the given operational scenario quantifies.","PeriodicalId":39125,"journal":{"name":"Advances in Military Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44202646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In accordance with the valid documents of the Army of the Czech Republic, a person using protective equipment has to be provided with an adequate fluid intake. To perform the work, it is necessary to equip the soldier with a hydration device that is resistant to chemical warfare agents and is structured in a way that allows its use when means of personal protection or other equipment is used. The aim of the experimental work was to verify resistance of the construction materials of hydration devices and to compare them. For this purpose, devices designed to provide resistance to chemical warfare agents and those that did not provide it were tested.
