城市道路平面交叉口现状分析和控制方案设计——以昆明市教场中路与教场北路交叉口为例

道路交叉口的交通信号控制,旨在通过减少平面交叉口内交通流所产生的冲突点和交织点,提高路口的通行能力,使交通流在交叉路口内能够确保安全并快速通过。城市道路交叉口往往交通流情况复杂,人员密集,交通流量大,一旦缺乏有效的交通控制方式,极易造成交通秩序混乱并引发交通拥堵。本文通过对昆明市一个道路交叉口交通现状进行调查与分析研究,设计并提出合理有效的交通控制方案。     

The Influence of Personal Values on Legal Judgments

The non‐legal factors that influence judicial decisions have been the subject of extensive debate. Theoretical and empirical work has focused on factors including political ideology, activism, attitudes, and demographics. Personal values are related to these factors and are central to decision making. The study described in this article translated theories and techniques from psychological research to examine the role of personal values in judicial decision making. A novel method of assessment of value expression in legal opinions revealed a different pattern of values expressed in the majority and minority opinions of a case that divided the Supreme Court. An empirical study of legal academics extended this analysis and highlighted the significant influence of personal values on legal decisions. The value:decision paradigm provides a new framework to analyse judicial decision making, judicial division, and judicial discretion and has significant implications for judicial diversity.     

Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.     

Estimating Individual Contributions to Complex DNA SNP Mixtures.,

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.
