Fuzzy logic for signal prediction in nuclear systems

In this paper, we present a fuzzy logic-based algorithm which allows to build a predictive model of an evolving signal. The if-then rules are inferred from the available input-output data. The errors of the model predictions with respect to the measured plant signals can then be used to detect, in real-time, any deviation of the process due either to a component's failure or to an operator's action. Applications of the approach are presented with respect to a chaotic time series of literature and to the water level in the steam generator of a PWR.     

射线诱导的细胞凋亡过程中端粒酶表达及其活性

利用原位端粒酶-凋亡双染色法检测A549细胞和L02细胞hTERT和凋亡双表达，端粒序列扩增检测(TRAP)方法检测群体细胞端粒酶活性，研究γ射线照射人肿瘤细胞和正常细胞后端粒酶的表达变化与凋亡-发生的关系。结果表明，1—SGy照射后24—72h，A549细胞和L02细胞内hTERT表达增强，端粒酶和凋亡双染色阳性细胞随照射剂量的提高而增多；在凋亡发生的过程中，群体细胞端粒酶活性呈剂量依赖性增强，提示放射线诱导人肿瘤和正常细胞凋亡可能不是通过直接抑制端粒酶活性的机制；而辐射诱导端粒酶活性增高可能是细胞修复辐射损伤的机制之一。

Signed Total Domination in Graphs

Let G = (V, E) be a simple graph. For any real valued function f: V→R, the weight of f is f(V) = ∑(v) over all vertices v ∈V. A signed total dominating function is a function f: V→|- 1, 1|such that f( N ( v ) ) ≥1 for every vertex v ∈ V. The signed total domination number of a graph G equals the minimum weight of a signed total dominating function on G. In this paper, some properties of the signed total domination number of a graph G are discussed.     

Blind Image Quality Assessment Based on Hybrid Fuzzy-Genetic Technique

A new method for no-reference image quality assessment based on hybrid fuzzy-genetic technique is proposed. Noise variance and edge sharpness level of the restored image are two basic metrics for assessing the performance of the restoration algorithm, then a fuzzy if-then inference system is developed to combine the two metrics to get a final quality score, and the parameters of the fuzzy membership function are trained with genetic algorithms. Experiments results show that the image quality score correlates well with mean opinion score and the proposed approach is robust and effective.
