英美刑法中的被迫行为是指行为人在他人或环境胁迫下所实施的形似犯罪,但是根据一定条件可以进行合法辩护的行为。被迫行为作为一种可宽恕的辩护事由,有其科学合理之处。文章分析了英美刑法中被迫行为的成立条件及其存在根据,并分析了其对我国刑法中的胁从犯立法的借鉴意义。 相似文献

随着我国城市现代化的进展加快,地铁交通已经存在于各大城市当中,对消防部队而言在抢险救灾中现代化的通信技术必不可少,综合通信保障技术能为消防部队赢得时间、及时发现险情并及时联络各相关应急部门,有效提高工作效益。本文笔者就消防部队在地铁环境下,常规使用的无线通信信号受到太大衰减后,抢险救灾中如何进行综合通信保障,并重点就同轴电缆通信进行了一些有益肤浅的探讨,和同仁共商榷。 相似文献

Evaluation of apple texture with contact acoustic emission detector: A study on performance of calibration models 总被引:1,自引:0,他引:1

Performance of calibration models for evaluation of apples sensory texture with contact acoustic emission detector (CAED) was studied. For model evaluation and testing, 2500 apples of 19 cultivars were harvested over two seasons. Apples were stored at normal atmosphere (NA), controlled atmosphere (CA) for different periods or were treated with 1-methylcyclopropene (1-MCP) in order to obtain a high variability of texture and fruit maturity. Apples were tested simultaneously in two distinct laboratories. The models were created and validated on averaged values from 10 fruits using simple linear regression, multiple linear regression (MLR) and principal component regression (PCR). Performance statistics of the models were expressed in terms of determination coefficient (R2), root mean square errors of cross validation (RMSECV) or prediction (RMSEP) and ratio of prediction to deviation (RPD). Firmness and total acoustic emission counts were predictors of sensory texture in the models. MLR and PCR models show better performance for prediction of sensory data than simple linear regression models however PCR models show the best results among models tested in this study. Common PCR models for several cultivars allow for successful prediction of hardness (RPD > 2.0), crispness and overall texture (1.5 < RPD < 2.0). The single-cultivar PCR models, constructed on data sets containing 26-39 averaged values, reveal significantly better performance (RPD > 2.0 for most of the cases) than the common PCR models for many varieties. 相似文献

This paper proposes an efficient, systematic and generalized multicriteria fuzzy optimum design method for the structural systems, using the suboptimization concept, introduction of measure membership functions and fuzzy decision‐making techniques. Each objective function is suboptimized first for all discrete sets of common design variables and design parameters. In order to make the relative evaluation of suboptimized data of objective functions rationally and systematically, and involve the fuzziness or tolerance in the decision‐making process and design emphases, the measure membership functions are introduced for all objective functions. The membership functions of the suboptimized objective functions are determined systematically using the corresponding measure membership functions as datum. A hybrid decision‐making process is developed combining the weighted operator method, comparison processes of maximum membership values and backward interpolation processes for the determination of the global optimum solution. The weighted operator method can also involve the relative emphases of each objective function simply. A design example of a practical prestressed concrete bridge system, in which the total expected cost after an earthquake and the aesthetics of the bridge system are the primary objectives, clarifies the applicability to any convex and non‐convex design problems, rationality, systematic design process and efficiency of the proposed design method.
