解酒妙方

大白菜解酒 将大白菜帮洗净,切成细丝,加些食醋,白糖拌匀后腌渍10分钟后食用,清凉酸甜又解酒。 雪梨解酒 取雪梨2至3个洗净切片搞成泥状,用纱布包裹压榨出汁饮服。 马蹄解酒 取马蹄(荸荠)10多只洗净捣成泥状,用纱布包裹压榨出汁饮服(此法最适于饮高粱等烈性酒醉患者)     

机动目标跟踪的模糊逻辑方法

作者描述了一种使用模糊逻辑理论推广的交互式多模型(IMM)算法。每一个卡尔曼滤波器都被认为是局部有效的,适用于滤波调节值所确定的目标加速度空间的区域。每个卡尔曼滤波器的有效性是由模糊集合和目标的加速度估值所决定的。用选择适当的模糊集合的叠区间判断接近加速度估值要求的模型的子集。仿真结果包括了典型的机动目标情况,它说明了不同形式的模糊集合的作用。这些证明了这种方法在估计精度和计算量两方面都比IMM优越。

爆炸冲击波对目标作用的等效计算模型

以爆炸相似律为依据,提出了计算机仿真计算爆炸冲击波对目标作用的等效模型,把远处某次爆炸对目标的作用等效为较近处另一能量的爆炸对该目标的作用。为用有限元法求解核爆炸冲击波对大型装备的毁伤破坏这一流固耦合动力学问题提供可以实施的基础。     

车轮浪漫曲

1949年1月,我在新泽西州的迪克斯堡结束了步兵基础训练,当时只有17岁的我正值年少气盛,血气方刚,感觉自己就像是电影《第一滴血》中兰博那样的硬汉。陆军派我到弗吉尼亚州的李营（现在的李堡）,担任营区司令部的办事员。我有生以来离开生长的纽约布鲁克林,到过最远的地方就是新泽西州的霍博肯了,因此当时的我可以说是心潮澎湃,急切地渴望着会有一番兰博式的冒险经历。     

A platform for initial testing of multiple camouflage patterns

The human visual system is still an important factor in military warfare; military personnel receive training on effective search strategies, and camouflage that can effectively conceal objects and personnel is a key component of a successful integrated survivability strategy. Previous methods of camouflage assessment have, amongst others, used psychophysics to generate distinctiveness metrics. However, the population from which the human observers are drawn is often not well defined, or necessarily appropriate. In this experiment we designed a new platform for testing multiple patterns based on a camouflaged object detection task, and investigate whether trained military observers perform better than civilians. We use a two-alternative forced choice paradigm, with participants searching images of woodland for a replica military helmet displaying Olive Green, Multi Terrain Pattern, US Marine Pattern or, as a conspicuous control, UN Peacekeeper Blue. Our data show that there is no difference in detection performance between the two observer groups but that there are clear differences in the effectiveness of the different helmet colour patterns in a temperate woodland environment. We conclude that when tasks involve very short stimulus presentation times, task-specific training has little effect on the success of target detection and thus this paradigm is particularly suitable for robust estimates of camouflage efficacy.     

Field test and probabilistic analysis of irregular steel debris casualty risks from a person-borne improvised explosive device

Person-borne improvised explosive devices (PBIEDs) are often used in terrorist attacks in Western countries. This study aims to predict the trajectories of PBIED fragments and the subsequent safety risks for people exposed to this hazard. An explosive field test with a typical PBIED composed of a plastic explosive charge and steel nut enhancements was performed to record initial fragment behaviour, including positions, velocity, and trajectory angles. These data were used to predict the full trajectory of PBIED fragments using a probabilistic analysis. In the probabilistic analyses a probability of fatality or serious injury was computed. Based on the results presented, many practical conclusions can be drawn, for instance, regarding safe evacuation distances if a person were exposed to a suspected PBIED.     

Improvement of VIS and IR camouflage properties by impregnating cotton fabric with PVB/IF-WS2

In order to examine the possibility to improve its camouflage properties standard cotton fabric with camouflage print was impregnated with poly(vinyl butyral), PVB and fullerene-like nanoparticles of tungsten disulfide, PVB/IF-WS₂. FTIR analysis excluded any possible chemical interaction of IF-WS₂ with PVB and the fabric. The camouflage behavior of the impregnated fabric has been examined firstly in the VIS part of the spectrum. Diffuse reflection, specular gloss and color coordinates were measured for three different shades (black, brown and dark green). Thermal imaging was applied to examine the camouflage abilities of this impregnation in IR part of the spectrum. The obtained results show that PVB/IF-WS₂ impregnation system induced enhacement of the materials camouflage properties, i.e. that IF-WS₂ have a positive effect on spectrophotometric characteristics of the fabric.
