INTRODUCTION Multiple injuries have been highlighted as an important clinical dimension of the injury profile following earthquakes, but studies are scarce. We investigated the pattern and combination of injuries among patients with two injuries following the 2008 Wenchuan earthquake. We also described the general injury profile, causes of injury and(More)
Based on the homomorphism of Lee et al, Xiang Guangli et al proposed similar module and implemented encrypting operations of addition, subtraction, multiplication and division over real number domain. There was additive and multiplicative homomorphism heretofore. But their cipher text leaks the information of decimal fraction, sign and relationship of big(More)
It has been suggested that the pathogenesis of vasospasm is complex including endothelial damage, oxidative stress, inflammatory damage, and the accumulation of toxic metabolites. Recently, a growing body of evidence indicates that nuclear factor erythroid 2-related factor 2 (Nrf2) plays a unique role in many physiological stress processes. In this study, a(More)
For the medical X-ray image with low brightness, low contrast and noise, we proposed an image enhancement algorithm which based on wavelet domain homomorphic filtering and contrast limited adaptive histogram equalization (CLAHE). Firstly, the image is decomposed by wavelet transformation, the image is decomposed into low-frequency and high-frequency(More)
Medical ultrasound image enhancement and denoising has been an important subject of medical image processing. Aiming at the shortcomings of the traditional ultrasonic image enhancement processing algorithm, this paper proposes a kind of ultrasonic image enhancement and denoising algorithm based on wavelet analysis theory and fuzzy theory, first of all for(More)
Construction activities involve many factors such as environment, economy and society. Residential buildings should not only meet living function, but also solve the environmental and social problems that they bring about. However, the present price of residential product has no measurable method on ecological impacts to apply and still stays in using(More)
With the rapid development of society, more and more attentions are paid to the problem of community safety. This paper proposes a kind of abnormal behavior detection method for the security issues of the residential areas. By judging of the direction of the movement, the method can decide whether the people have abnormal behavior. It gives the(More)
This paper researches on the energy saving economy of the oil pipeline in gaosheng when the second heat station stops heating. First, every month total heat transfer coefficient is calculated according to the historical pipeline operation data and the temperature of the soil at the buried depth with the method of least squares. Second, basing on every month(More)
