物证摄影的图像融合修复
Renovating Forensic Photography by Image Fusion
 [PDF]


Journal of Image and Signal Processing (JISP) , 2013, DOI: 10.12677/JISP.2013.24007
Abstract: 图像融合是提取各自信道图像中的有利信息,以综合形成高质量图像的一种专门技术。本文在对图像融合的基本技术原理进行简要分析基础上,结合Photoshop软件融合操作,将图像融合的技术应用与物证检验摄影有机结合,有效地解决了物证摄影的信息全面性和原始保留等问题,对痕迹物证的检验提取工作有较强的借鉴意义。
The image fusion is a technique which integrated to form high quality image by the extraction of useful in-formation in the image of each channel. Having briefly analyzed the basic principle of image fusion and combined with the operation of Photoshop in this paper, the author organically combined the technology application of image fusion and forensic photography, which effectively solved the problems about information comprehensiveness and the original reservation (and so on) in forensic photography. It has a strong referential significance for inspection and identification.

Abstract:
本文在分析北京市商品住房市场供求非均衡现状引起房价的持续上涨的基础上,构建了房地产供求的非均衡对数计量经济模型,得出了商品住房供求受人均可支配收入、商品住房价格、人们的预期、房地产成本、城市规模等因素影响的结论。进一步采用1994~2011年的相关商品住房统计数据进行实证分析,计算出了历年北京市商品住房市场有效供求的非均衡度,发现非均衡度可以灵敏的反映出北京市房地产市场有效供求关系的波动状态,并分三个阶段对非均衡度给予了现实的解释。最后,对北京商品住房市场向瓦尔拉斯均衡逼近,提出了相应的政策建议,可作为政府宏观调控的参考依据。
This paper constructed the econometric model of demand and supply disequilibrium logarithm based on the analysis of sustained increases in housing prices caused by the unbalanced supply and demand situation in Beijing commercial housing market. The demand and supply of commercial housing were affected by per capital disposable income, commercial housing price, people’s expectations and the cost of housing, city scale etc. It is further carried out by the empirical re-search with 1994~2012 statistical data. Meanwhile, the disequilibrium degree index of the effective demand and supply of commodity housing that can reflect the undulation actual situation of Beijing commercial housing was calculated. Besides, this paper gave a realistic interpretation for the disequilibrium degree from three stages. Finally, it gave the corresponding policy recommen-dations about approximate approach to Watras equilibrium as reference for the government ma-croeconomic regulation and control.

Linear preserve problem has been a relatively active topic in the matrix theory research. In the paper, we mainly study invertible linear operators that preserve {1,2}-inverses of matrices over semirings. It is completely characterized that invertible linear operators which preserve {1,2}- inverse of matrices over chain semiring, the nonnegative integers, and the nonnegative reals.

Abstract:

我国电动汽车逐步进入产业化发展阶段,仍面临着产品价格过高,市场需求不足,尤其是消费者购买意愿不强等困境,导致电动汽车行业还无法迅速达成产业规模。因此,在电动汽车产业发展初期,需要相关政策手段予以支持,最常见的即是实施财政补贴。但是,目前电动汽车补贴政策存在着过补贴过低,补贴种类过于单一问题,严重影响补贴效率,进而影响政府对电动汽车行业的支持力度,乃至中国新能源汽车的发展战略。本文从博弈论角度,建立政府、汽车企业,和消费者的三阶段斯塔克博格博弈,得出政府对电动汽车补贴的最优额度。在此基础上,引入电动汽车节能减排公式,重点分析电动汽车节能减排效益,试图向政府提出制定电动汽车补贴政策的合理建议。
China’s electric vehicles has gradually entered the industrialization stage of development, facing complex situations and difficulties, such as high price and low demand, especially the weak consumer purchase intention. All these have made that electric vehicle industry still unable to reach the scale of the industry quickly. Thus, in the initial stage of the development of electric vehicle industry, we need policy measures to support it and the most common one is implementation of financial subsidies. However, the present electric vehicle subsidies are too low and single, which seriously affects the efficiency of policy, and even the development strategy of China’s new energy vehicles. Based on the game theory, this paper has built a three-stage Stackelberg model, which contains government, automobile enterprises and consumers, and obtained the optimal amount of government subsidies for electric vehicle. Then, it introduces the energy efficiency formula for electric vehicles, trying to give reasonable advice to government on the electric car subsidy policy.

Abstract:
细菌耐药性是当前最紧迫的公众健康问题之一,尤其在目前新型抗菌药物研发落后于耐药菌进化速度的情况下,细菌耐药性的发生、传播以及消除的机制,已经成为人们关注的热点。近来研究发现,细菌DNA损伤诱导反应(SOS反应)在细菌进化耐药性的过程中扮演着重要角色。在这里,本文对SOS反应与细菌耐药性的关系、研究进展以及当前存在问题作一阐述。
Bacterial drug resistance is one of the world’s most pressing public health threats. Especially in today, new antimicrobial drugs are no longer being developed at a rate that can keep pace with microbial evolution. The mechanism for the emergence, spread and reversion of bacterial resistance has become a research hotspot. Recently, it has been proved that bacterial DNA damage response (also named SOS response) acts an important role in the evolution of drug resistance. Here, we reviewed the relation between SOS response and bacterial drug resistance.

As a prominent personality, impulsivity affects the human mind and behavior controlling, and it also affects the occurrence of suicide. Objective: To survey overview of suicidal ideation and attempted suicide of high school students in Chongqing, and to discuss the relationship between impulsive personality traits and suicidal ideation, attempted suicide. Methods: The number of the total sample is 12,024, which is from 11 high schools of Chongqing. We use the Chinese version of Barratt Impulsivity Scale, the suicidal ideation scale, and the attempted suicide scale to survey the students. Result: 1) The suicidal ideation score of high school students in Chongqing is 5.80 ± 2.41; 2) Detection rate of attempted suicide occurred by 2.6%; 3) The impulsive personality traits are the important factor to suicidal ideation; 4) Impulsive personality traits are predictors of attempted suicide. Conclusions: The impulsive personality traits can forecast the strength of suicidal ideation and the attempted suicide from different degrees.
