We propose a hybrid technique for image encryption which employs the concept of carrier image and SCAN patterns generated by SCAN methodology. Although it involves existing method like SCAN methodology, the novelty of the work lies in hybridizing and carrier image creation for encryption. Here the carrier image is created with the help of alphanumeric keyword. Each alphanumeric key will be havi...

Metal-halide perovskites are at the frontier of optoelectronic research due to solution processability and excellent semiconductor properties. Here we use transient absorption spectroscopy to study hot-carrier distributions in CH3NH3PbI3 and quantify key semiconductor parameters. Above bandgap, non-resonant excitation creates quasi-thermalized carrier distributions within 100 fs. During carrier...

BACKGROUND Carrier status of a structural balanced chromosome abnormality is associated with recurrent miscarriage. There is, at present, no evidence of the impact of the sequence of preceding pregnancies on the probability of carrier status. The aim of our study was therefore to examine whether the history of consecutive versus non-consecutive miscarriages in couples with two or more miscarria...

Mandatory alcohol testing programs for motor carrier drivers were implemented in the United States in 1995 and have not been adequately evaluated. Using data from the Fatality Analysis Reporting System during 1982-2006, the authors assessed the effectiveness of mandatory alcohol testing programs in reducing alcohol involvement in fatal motor carrier crashes. The study sample consisted of 69,295...

in maritime transport law deck carriage is an important issue. whether a carrier is or is not allowed to carry goods on deck is a question that must be answered in each case and according to international rules and conventions (such as hague rules, hamburg and rotterdam conventions) and domestic laws and regulations (including maritime law of iran) governing the carriage as well as the type and...

—Under high dynamic and weak signal environment in the satellite Tracking, Telemetry and Command (TT&C) systems, the carrier acquisition and tracking can’t be easily achieved. In this paper, an improved two-stage high dynamic and weak signal carrier acquisition and tracking are presented for perfect carrier synchronization. The typical U.S. Jet Propulsion Laboratory (JPL) high dynamic carrier ...
