Evaluation of a clinical scoring system for canine demodicosis
Veterinary Dermatology, Volume 32, Issue 4, Page 311-e84, August 2021., 2021 Background – Canine demodicosis is a common disease in small animal practice. Although a number of studies evaluating treatment efficacy for canine demodicosis have used clinical scoring systems, none have been validated. Objectives – This study evaluated the validity, reliability, reproducibility and sensitivity to change of a clinical scoring system ...

Parametric modeling of 3D fish body(三维鱼体参数化建模)
Zhejiang Daxue xuebao. Lixue ban, 2022 因水下环境复杂，鱼类三维模型获取非常困难，基于三维鱼类数据驱动的很多自动化研究工作无法开展。为此，提出一种三维鱼体参数化建模方法。首先，用专业建模师构建的标准鱼体模板注册扫描仪采集三维鱼体数据，构建拓扑结构一致的三维鱼体网格数据集；其次，用主成分分析法对数据集中的三维鱼体网格模型进行建模分析，建立鱼体的参数化表示模型；最后，采集草鱼数据进行相关实验。实验结果表明，注册得到的三维鱼体模型与真实扫描鱼体模型顶点之间的平均均方根误差仅为0.691 3 mm，在可接受范围 ...

Journal of Traumatic Stress, Volume 33, Issue 1, Page 41-51, February 2020., 2020 Abstract The 11th revision of the World Health Organization's International Classification of Diseases (ICD‐11) includes a new disorder, complex posttraumatic stress disorder (CPTSD). The network approach to psychopathology enables investigation of the structure of disorders at the symptom level, which allows for analysis of direct symptom interactions.

Journal of Analytical Psychology, Volume 65, Issue 1, Page 88-115, February 2020., 2020 Abstract The various ways schools of psychotherapy relate to dreams have been marked by isolationism and mutual conflict rather than self‐examination and then integrating the discoveries and methods of other schools. Jung’s method was in opposition to Freud’s psychoanalysis. Existential psychology was dismissive of Freud’s and Jung’s discoveries, while

Zhejiang Daxue xuebao. Lixue ban, 2007 最近，HON和WEI给出了求解各向同性热传导反问题的基本解方法.该方法提供了一种在整个时间空间区域上的行之有效的数值格式.本文尝试将该无网格方法推广应用于求解各向异性材料中热传导方程的时间反向问题.首先，通过变量转换得到该问题的控制方程的基本解.接着，应用截断奇异值分解和L-曲线准则求解所得的高度病态的线性方程组.最后给出几个数值例子展示本方法的有效性，并分析了解的精度跟参数T、最终时刻的关系.

Analysis on flow characteristics and aerodynamic-force-induced vibration of supersonic rocket-sled
Xibei Gongye Daxue Xuebao, 2022 目前, 火箭橇试验是飞行器空气动力学重要试验手段, 然而强烈的地面与轨道干扰会影响试验的精度, 甚至导致试验失败。采用尺度自适应SAS方法和基于铺层算法的动网格技术对不同马赫数下的超声速火箭橇滑行过程进行数值模拟, 探究了超声速火箭橇的气动力致振机理。采用了数值风洞模拟方法对超声速火箭橇无限空间绕流和仅包含地面的橇体绕流进行仿真, 分析了不同环境条件下的激波特征。结果表明: 超声速火箭橇的头激波传播至轨道和地面时会发生激波反射, 反射激波的存在会导致超声速火箭橇产生升力, 并带来阻力的略微增加 ...

Fast construction of 2D offset curve based on distance field(基于距离场的二维偏移曲线快速生成方法)
Zhejiang Daxue xuebao. Lixue ban, 2017 提出了一种快速生成二维偏移曲线的方法.对于无自相交的二维多边形曲线，该方法能构造无自相交、保留准确尖锐特征的二维等距偏移曲线.算法的基本思想：先在一个均匀网格上根据给定的曲线采样一个局部有向距离场，然后使用等值线抽取方法从有向距离场中获取偏移曲线.在构造局部距离场时引入3个过滤器，在远离偏移曲线的区域消除大量冗余计算.采用经典MS(marching square)方法抽取初始多边形偏移曲线，通过一个混合解析解和二分搜索方法，快速计算得到偏移曲线与网格边的准确交点 ...
