this paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. system engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (tco...
To improve e-ciency of compressed image retrieval, we propose a novel statistical feature extraction algorithm in this paper to characterize the image content directly in its compressed domain. The statistical feature extracted is mainly through computing a set of moments directly from DCT coe-cients without involving full decompression or inverse DCT. Following the algorithm design, a content-...
Modeling is widely accepted to be essential to design activity. A major benefit is the use of formal methods for analysis and predictability. In Polychrony, the tool-set of the Signal language, a component-based approach have been defined to model avionics applications. This approach uses Signal models of so-called APEX services based on the avionics standard ARINC 653. This gives access to the...
In this work the optimal design of sensor networks for chemical plants is addressed using stochastic optimization strategies. The problem consists in selecting the type, number and location of new sensors that provide the required quantity and quality of process information. Ad-hoc strategies based on Tabu Search, Scatter Search and Population Based Incremental Learning Algorithms are proposed....
Microwave diplexers are often designed iteratively via manual channel-by-channel or resonator-by-resonator local optimization procedures due to high dimensionality in design variables and the complexity of structures. A one-off automated diplexer method is yet be developed. To achieve this, other than improved optimizers, an effective objective function (OF) critical allow optimizers find desir...
