This paper presents an additive approach to transform-domain information hiding and the performance analysis for images video. The watermark embedding method is designed satisfy perceptual constraints improve detectability as well rate. statistical behaviors of subband coefficients are modeled by generalized Gaussian distribution. structure optimum detection built exact asymptotic evaluated using large deviation theory. Our can not only achieve good transparency but also precisely control...
Digital watermarking is an emerging technique to protect data security and intellectual property right. Identification or verification of patterns can be achieved by detecting watermarks in received signals. However, one the biggest challenges detection that strengths watermark signals will change after being distorted attacker a channel. Meanwhile, embedding may adapted original signals, which are unknown at receiver end. Further, often highly non-Gaussian. Although some work has been done...
Ionic liquids (ILs) are molten organic salts consisting of cations and weakly coordinating organic/inorganic anions at room temperature. ILs have excellent physical chemical properties such as high thermal stability, combustible temperature, miscibility with compounds so on, making them good candidates for performance lubricants lubricant additives. The functional designability makes novel lubrication materials that can break through the bottleneck active control friction lubrication. This...
Tolerance allocation optimization (TAO) is a crucial step in the manufacturing process of portal milling machine (PMM). Traditional design approaches often consider only machining errors arising from geometric errors. However, thermal characteristics bi-rotary head (BRMH), which significantly tool accuracy, are frequently overlooked. Hence, novel TAO model PMM proposed, considering BRMH across multiple operating conditions. Firstly, based on multi-body system (MBS) theory and homogeneous...
A flexible manufacturing system (FMS) improves productivity and makes it more efficient. Maintaining reliability levels reducing costs through proper maintenance strategies are key problems for the development application of a FMS. This paper proposes grouping preventive strategy FMS with optimized parameters by considering both cost. In this work, three-layer evaluation index is first presented to accurately estimate FMS; weights each layer were obtained importance modeling analysis,...
In terms of creating customized products rapidly, modularity is deemed to be an effective developmental strategy for handling product variety and intricacy. order develop reasonable modular architecture with physically detachable modules, a new systematic structured approach modularization based on axiomatic design structure matrix proposed. The decomposed hierarchically into its functional, physical, process domains using method. After transformation from matrix, the pertinence matrices...
