Captured Kriegsmarine Enigma Documents at Bletchley Park

Abstract

The discovery of intercepts in the Japanese “Orange Translations” regarding the sinking of merchant ships (marus) bearing allied POWs led to the conclusion that the Joint Intelligence Center Pacific Ocean Area (JICPOA) gave latitudes and longitudes of these vessels to the Commander, Submarine Force, Pacific (ComSubPac) knowing that POWs would be killed. An examination of the “Orange Translations” reveals that most of the intercepts are from the Japanese Water Transport Code (2468) system, not the “Maru Code” (JN-11). The author concludes that while JICPOA provided ComSubPac with convoy coordinates, they were unaware of the presence of POWs on the marus.

电子对抗团首长机关指挥训练系统设计

电子对抗团首长机关指挥训练系统由导调工作、模拟仿真、技能训练、指挥训练、军事地理数据库和部队信息数据库组成.系统单独作业时只安装参训员用机系统,联网作业时需安装导演机和网络服务器软件系统.登录系统后,通过席位选择明确各作业台身份及权限,确定相应作业台个数,以保证身份唯一性.进入使用状态后,先作训练准备并更新系统数据资料,再进行训练实施阶段.     

莫高窟第281窟大都督王文通供养像补正——兼论敦煌服饰研究中的一些问题

本文通过考察莫高窟第281窟的所有供养人像,认为“大都督王文通供养像”应该是窟内南壁现存隋代供养人像东起第二身,而非一直被学界认为的西壁南侧较大一身男子像。由此提出敦煌服饰研究中所使用的出版物图片或壁画临摹品等存在的一些问题,认为研究应基于对壁画本体的反复辨识,将图像置于洞窟的原生语境中进行考察,以得到更加真实而全面的结论。     

REVIEWS OF THINGS CRYPTOLOGIC

ABSTRACT

In an effort to support its massive conspiracy theory headed by President Franklin D. Roosevelt to get the United States into the European war and it continuing cover-up, Day of Deceit misinterprets, misstates, and omits much of the old and some new cryptologic information surrounding the Japanese attack on Pearl Harbor. In spite of this huge research effort by the author, Robert B. Sinnett, it is still clear that no U. S. official knew about the attack beforehand.
