This work presents the design and testing of piercing ammunition for 73 mm recoilless canon with fragmentation and thermobaric effect. The advantages relative to its intended use are represented by its capability to pierce reinforced concrete and light armored targets, the fragmentation and thermobaric explosive delayed effect, capable to neutralize both soft targets and structures, and the reduced mass and dimensions of the armament system intended to be used. The warhead is composed of a piercing projectile with thin wall in order to accommodate an explosive charge with thermobaric effect, initiated by a bottom fuse. The warhead is coupled with a rocket motor in order to augment the initial velocity of the projectile for the maximization of the piercing capability. The paper presents the process of forging and machining of the warhead shell as well as the numerical simulation regarding the terminal ballistics of the ammunition, which was validated trough live fire experiments.","PeriodicalId":315050,"journal":{"name":"Journal of Military Technology","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128276527","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 used water, in order to be released in the stream flow, must be treated to eliminate the toxic substances. Strippable coatings visibly minimize the amount of waste resulting from the decontamination process. Biodegradable films based on polyvinyl alcohol were synthesized and used within this study. The polymeric coatings also contains Bentonite nano-clay (BT) that is a rheological agent, a complexing agent used to entrap the heavy metal or radioactive particles and glycerol used as an additive to give the films the proper mechanical properties. Nevertheless, the used coatings must also be disposed of in a certain way. This paper studies few methods in which strippable coatings that are presented as chemical and/or radioactive waste are treated and proposes means to reutilize used films that are or/are not contaminated, but also suggests a simplified technological process for producing such decontamination solutions.","PeriodicalId":315050,"journal":{"name":"Journal of Military Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130701514","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}

Device Centric Cloud Signature Solution under eIDAS Regulation eIDAS法规下以设备为中心的云签名解决方案

{"title":"Device Centric Cloud Signature Solution under eIDAS Regulation","authors":"P. Scurtu, V. Patriciu","doi":"10.32754/JMT.2020.2.08","DOIUrl":"https://doi.org/10.32754/JMT.2020.2.08","url":null,"abstract":"Digital Object Identifier 10.32754/JMT.2020.2.08 49 1Abstract—Under the new eIDAS Regulation qualified electronic signatures are equivalent, from a legal stand, to handwritten signature. Traditional signature solutions make use of cryptographic materials stored in secure devices in possession of clients, while remote or cloud signatures solutions rely on a trusted service provider which manages the private keys and produces signatures in a remote manner. This shifts the weight of dealing with the keys off clients and moves this duty to a specialist in the field. As opposed to a classical Qualified Electronic Signature, a cloud-based solution has to solve a set of specific problems: the integrity of the data submitted must be ensured, the user’s intent of creating a digital signature must be demonstrated and the owner of the cryptographic key must be the only entity capable of using this cryptographic material. A device centric solution based on a simple mobile device application is proposed. This solution leverages the advancements in device technology such as the inclusion of Trusted Execution Environments (TEEs) on end user terminals. Furthermore, in comparison to similar solutions, the costs have been reduced by replacing cryptographic solutions based on SMS messages or cryptographic tokens with a device native implementation.","PeriodicalId":315050,"journal":{"name":"Journal of Military Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123441119","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}
