Secure Analog Data Transmission Based on Rössler Chaotic System Behavior
("Dunarea de Jos" University of Galati, 2000)This paper describes a new methodology for increasing the security of analog data transmission based on a mixture of the original analog signal with one of the state variables of Rössler chaotic system. The method is ... -
Security Policies Approached by Value Analysis Concepts
(Universitas Galatiensis, 2006-01)This paper intends to redefine the role of the end users of the Internet facilities, in the process of creation of more secure transactions on the Internet, in respect of their privacy. In this context, the purpose is ... -
Securizarea sistemelor informatice şi de comunicaţii prin criptografia cuantică
(Universitatea "Dunărea de Jos" Galaţi, 2012)Principalul punct slab al unui sistem criptografic și de comunicații este acela că orice transmisie securizată poate fi făcută numai după ce cheia de criptare este comunicată în secret printr-un canal de comunicații ... -
Seismic Base Isolation of Structures Using Frictuon Pendulum Bearings
(Universitatea 'Dunărea de Jos" din Galați, 2011)Base isolation systems have become a significant element to enhance reliability during an earthquake. One type of base isolation system is Friction Pendulum Bearing in which the superstructure is isolated from the foundation ... -
Seismic Isolation and Energy Dissipation Systems for Safe Structures
(Universitatea "Dunărea de Jos" din Galați, 2012)The seismic protection of buildings has been a successful strategy for the past 30 years. Seismic protection systems ensure the safety of any type of building even under most severe earthquakes. Seismic devices not ... -
Seismic Protection of Structures Using Hydraulic Damper Devices
(Universitatea "Dunărea de Jos" din Galați, 2010)In recent years, much attention has been paid to the research and development of structural control techniques with particular emphasis on alleviation of wind and seismic responses of structures. Structural control in civil ... -
