专利权的侵害赔偿探讨——兼谈运用资产评估方法计算专利权的侵害赔偿

专利权的侵害赔偿是指专利权人的财产权益受到侵犯后,其经济损失由侵害人予以补偿。有三种损失赔偿的确定方法。一是以专利权人因侵权行为受到实际损失作为赔偿数额;二是以侵权人因侵权行为获得的全部利润作为损失赔偿额;三是以不低于专利许可使用费用的合理数额作为赔偿额。在复杂和特殊情况下,运用资产评估法则不失为一种较好的方式。对专利权这种无形资产的评估,最常用的方法是收益现值法和重置成本法

构建和谐社会:完善我国的家庭暴力损害赔偿制度

家庭暴力是影响社会和谐发展的一个重要问题。我国婚姻法规定了家庭暴力损害赔偿制度,但该制度在损害赔偿的主体、范围等方面存在一些不足之处。进一步完善家庭暴力损害赔偿制度,遏制家庭暴力,是构建社会主义和谐社会的必然要求。     

Kinematic analysis of the double side kick in pointfighting,kickboxing

The double side kick is a frequently used technique in pointfighting on which most offensive kicking techniques are based on. The aim of the study was to identify parameters, e.g., trunk and leg positions, durations and velocities that affect successful technique execution.

44 fighters, male and female, including European and World champions, participated in the research. The participants performed double side kicks to a punching bag with the target at chest level. 10 international experts scored (1–10 points; interrater correlation ICC (3,1): 0.952) videos of the best individual trial for quality of technique execution. Based on the average of the scores participants were categorised into 2 equally sized groups. For kinematic data acquisition, a Vicon 3D-motion capturing system was used. The normalised knee height of the kick leg (KHK), normalised absolute distance to the frontal shoulder (DKS) at the end of both chambering phases, the horizontal velocity during both chambering phases (KEV), the durations of all 6 functional phases and total duration, were analysed.

KHK1, KHK2, DKS1 and DKS2, total duration as well as 4 out of 6 phase durations and KEV1 showed significant differences between groups in two-sided t-test or Mann–Whitney U-test for not normally distributed variables.     

Kinematics of judo breakfall for osoto-gari: Considerations for head injury prevention

Previous studies suggest that increasing the skill level of judokas will decrease the number of head injuries sustained during judo. However, the kinematics are poorly understood, making it difficult to establish an effective breakfall teaching programme. Therefore, we studied the kinematic parameters of breakfall for osoto-gari to identify the risk of judo-related head injuries by comparing experienced and novice judokas. This information will provide insight into developing a better prevention plan for judo-related head injuries.

A total of 10 experienced and 12 novice judokas volunteered to participate in this study. The kinematic data of the breakfall motion for osoto-gari were collected using a three-dimensional motion analysis technique (200 Hz).

We observed a significantly higher peak neck extension momentum in the novice group than in the experienced group. This suggests that neck extension momentum during breakfall is associated with the risk of head injuries during judo. In addition, the novice judokas demonstrated a significantly greater flexed pattern in the trunk and hip movement than the experienced judokas (P < 0.05). The results suggest that the trunk and lower extremity motion are important kinematic parameters that determine the skill level in performing the breakfall for osoto-gari.     

基于减聚类ANFIS模型的船舶横摇运动实时预测

为准确高效地预测船舶在波浪中的航行状态以保证人员、货物和船舶的安全,提出一种基于减聚类的自适应神经模糊推理系统(Subtractive Clustering based Adaptive Neural-Fuzzy Inference System,SC-ANFIS)模型.SC-ANFIS模型使用减聚类算法对输入样本进行聚类分析,得到模糊规则数,并建立神经模糊推理系统,再使用结合BP算法与最小二乘估计算法的混合算法对建立的预测系统进行优化训练,得到最优的预测系统模型,并使用自相关分析确定预测系统模型的输入.运用该模型对大连海事大学科研教学船"育鲲"号的横摇运动进行实时预测,结果验证了该方法可行、有效,并具有较高的预测精度.     

Effect of the starting and turning performances on the subsequent swimming parameters of elite swimmers

In the present research, we examined the effect of the starting and turning performances on the subsequent swimming parameters by (1) comparing the starting and turning velocities with the swimming parameters on the emersion and mid-pool segments and (2) by relating the individual behaviour of swimmers during the start and turns with subsequent behaviour on each swimming lap. One hundred and twelve 100 m performances on the FINA 2013 World Swimming Championships were analysed by an image-processing system (InThePool 2.0®). At the point of the start emersion, the swimming parameters of the 100-m elite swimmers were substantially greater than the mid-pool parameters, except on the breaststroke races. On the other hand, no diminution in the swimming parameters was observed between the turn emersion and the mid-pool swimming, except on the butterfly and backstroke male races. Changes on the surface swimming kinematics were not generally related to the starting or turning parameters, although male swimmers who develop faster starts seem to achieve faster velocities at emersion. Race analysts should be aware of a transfer of momentum when swimmers emerge from underwater with implications on the subsequent swimming kinematics, especially for male swimmers who employ underwater undulatory techniques.
