Spectral clustering algorithms are newly developing technique in recent years. In this paper, we derive a new pairwise affinity function for spectral clustering based on a measure of texture features represented by Gaussian Markov Random Field (GMRF) model. This model is used to capture the statistical properties of the neighborhood at a pixel, and then pairwise affinities represented by it can cluster the pixels into coherent groups. Having obtained a local similarity measured by regions of coherent texture and brightness, we use the normalized cuts to find partitions of the image. Experimental results demonstrate that the proposed method is effective and robust for image segmentation.

Cloud model can be used for reliability evaluation when the working condition is changeable and described by the qualitative linguistic values. It is neglected that the most typical sample in cloud model also contains some uncertainty when evaluate the reliability of products using cloud model. For this reason, a cloud model is used to describe the uncertainty of the most typical sample. The experimental results show that the reliability evaluation result is closer to the reality when using the cloud model that considering the uncertainty of the most typical sample.

Thermoforming is one of the most versatile and economical processes available for polymer products. The cooling process is one of the key processes of thermoforming which effects to quality of final products. In this study, two kinds of 1-d analysis models were developed under the condition of checking the possibility of changing a 2-d to a 1-d problem in a previous study. At first, a model for stability analysis of the cooling system was developed under the condition of considering ABS sheet and mold as lumps. In order to get time-dependent temperature distribution of ABS sheet, another model was developed. The 1-d analysis codes can be widely used for designing the cooling system of thermoforming.

In this paper, we propose a robust approach to denoise in forward looking infrared (FLIR) imagery taken from an airborne moving platform. We use morphological filters to reduce noise and clutter and better preserve important details. Based on target intensity and shape information, motion criteria, the proposed algorithm uses morphological filters by reconstruction to estimate background of image, and proposes adaptive nonlinear wavelet using the lifting scheme to remove Gaussian white noise. The experiments performed on FLIR image sequences, show the robustness of the proposed approach.

Key management in sensor networks has become a challenging issue in the design and the development of secure wireless sensor networks since asymmetric cryptosystems are unsuitable for use in resource constrained sensor nodes, and also because the nodes are vulnerable to physical capture. In this paper, we present a new key management scheme using sub key pool to enlarge the size of key pool. With the more keys in the key pool, this scheme has higher security against node capture. The analysis shows that this scheme provides better security compared to the previous approaches, and can ensure reasonable connectivity at the same time.
