- A noise reduction method in CT images has been proposed. Its algorithm performs a local noise assessment by means of separate reconstructions of two non-intersecting subsets of the set of projections of a given image.
- Shearlet systems have been opted in order to obtain such statistical assessment because of their highly directional presentation together with optimal sparse approximations of anisotropic information and rapid numerical realization.
- The change rate criterion for the Shannon entropy is used to determine the soft threshold mask for processing the high-frequency coefficients of the averaged image obtained from the two input reconstructions.
- The comparison between the proposed method and the techniques using certain threshold constants shows the advantage of the former in terms of both quantitative measures and visualization quality.

- The industrial process consumes quite a huge amount of energy.
- The cost of energy consumption is closely behind the cost of raw materials in the determination of the cost of production.
- The use of programmable logic controller ladder diagram with the Fuzzy logic controller is successfully implemented to effect energy saving in the process industry.
- There is a noticeable and significant improvement in energy and cost saving with the implementation of the approach

- A Markov model is proposed for the impact of human error modeling on failure rate of the protection system.
- The optimum time interval of routine test of protection system is determined.
- The proposed Markov model is applied to the protection system of power transformers.
- Results show that the human error rate has a significant impact on the increase of failure rate and decrease of the optimum time interval of routine test of the protection system.
