电池电动汽车(BEV)的主要挑战之一是续航里程是否足够,因此在任何最近的车辆概念中,最大化的电池体积是合乎需要的。悬架作为最大的电动汽车子系统之一,对这一点有着重要的影响。本研究目的是使用自动化方法进行悬架开发,主要是引入一种新的可转向后悬架概念与电力推进系统,即从配备内燃机(ICE)的传统汽车开始,开发一种悬架,以满足纯电动汽车的新装配要求,同时保持有关驾驶动力学的典型要求。悬架概念是为具有大电池尺寸的高级汽车而优化的,此外还考虑了先进的主动系统,如空气弹簧和大转向角的主动后轮转向。该概念还提出了一种具有良好调整运动学性能的封装解决方案,符合原始设备制造商的调整理念。为解决由此产生的高复杂性,使用了新开发的方法,即运动学优化是用一种创新的方法完成的,该方法根据给定的要求自动提出新的硬点。在设计中,使用简化模型来表示复杂零件的形状,因此可以从包装的角度自动判断运动学概念是否可行。结果表明,新的悬架概念可以处理具有挑战性的装配问题和复杂的运动学要求。

The amount of water stored in snowpack is the single most important measurement for the management of water supply and flood control systems. The available water content in snow is called the snow water equivalent (SWE). The product of snow density and depth provides an estimate of SWE. In this paper, snow depth and density are estimated by a nonlinear least squares fitting algorithm. The inputs to this algorithm are global positioning system (GPS) signals and a simple GPS interferometric reflectometry (GPS-IR) model. The elevation angles of interest at the GPS receiving antenna are between 50 and 300. A snow-covered prairie grass field experiment shows potential for inferring snow water equivalent using GPS-IR. For this case study, the average inferred snow depth (17.9 cm) is within the in situ measurement range (17.6 cm ± 1.5 cm). However, the average inferred snow density (0.13 ***-3) overestimates the in situ measurements (0.08 ***-3 ± 0.02 ***-3). Consequently, the average inferred SWE (2.33 ***-2) also overestimates the in situ calculations (1.38 ***-2 ± 0.36 ***-2).

This review focuses on the early diagnosis of anal cancerand its precursor lesions through routine screening. A number of risk-stratification strategies as well as screening techniques have been suggested, and currently little consensus exists among national societies. Much of the current clinical rationale for the prevention of anal cancer derives from the similar tumor biology of cervical cancer and the successful use of routine screening to identify cervical cancer and its precursors early in the disease process. It is thought that such a strategy of identifying early anal intraepithelial neoplasia will reduce the incidence of invasive anal cancer. The low prevalence of anal cancer in the general population prevents the use of routine screening. However, routine screening of selected populations has been shown to be a more promising strategy. Potential screening modalities include digital anorectal exam, anal Papanicolaou testing, human papilloma virus co-testing, and high-resolution anoscopy. Additional research associating high-grade dysplasia treatment with anal cancer prevention as well as direct comparisons of screening regimens is necessary to develop further anal cancer screening recommendations.

Cassirer's Revision of Cohen

Introduction to Fluid Mechanics

作者： ira Irit Katsur Hebrew University of Jerusalem

Ernst Cassirer has been proclaimed a follower of Hermann Cohen. However, Cassirer modified the basic concepts of Cohen's theory of knowledge, so that Cassirer'sphilosophical positions in many aspects actually stand in opposition to Cohen's. Although Cassirer did follow Cohen'smethodology coherently, in that path he refuted the main positions of his teacher. Cohen's philosophical task was forwarding Kant's critical method to construct a theory of knowledge. He aimed not only to renew Kant's method in the way he interpreted it, but also to revise, in accordance with Kant's method, the uncritical positions of Kant's own theory of knowledge. Cohen's methodology was intended to achieve this goal. In following his teacher's task, however, Cassirer developed a set of functional concepts which coherently reveal and overturn the uncritical positions in the theory of knowledge, including the one essential for Cohen himself. Consequently, it may be said, Cassirer "revises" Cohen'ssystem in a same way that Cohen revised Kant.
