鉴于已有ME版,Civil, ME, Aerospace等学科都是力学学科,
因此建议将ME版改称Mechanics版,这样Civil, Aerospace等学科的人都可以
参加讨论。
BTW, ME版讨论并不多。

有自己的组织就不一样了?
Civil的三大块,structural, hydraulics and geotechnics那个不是力学。
就如同mechanical的Design/solid, fluid/thermal and control都是力学一样。
不会有多少人参加讨论的,就如同现在的ME版。
我看还是设立一个mechanics版,这样mechanical, civil and aerospace
都可以参加讨论。关于socialization or networking,在这个mechanics版更好,
视野更开阔。比如做hydraulics的可以考虑到aerospace industry去做CFD,
做control可以了解hydro project's dam seismic design等等。
其实大家学的做的都是一样的,只是针对对象不同罢了。

It would be more accurate to call that board "Aerospace" .
Aerospace emphasizes science and technology related issure, while aviation
refers to the activities like piloting an aircraft. They are not quite the
same.
I strongly support macrowave's idea to have a board/club that every aviation
enthusiast can enjoy.

香港——当美国空军希望增强军用机器人的感知力时,他们向一家位于波士顿的人工智
能初创公司Neurala求助。但是当Neurala需要钱时,美国军方几乎没有做出什么反应。
所以Neurala找到了中国,从一家得到中国国有公司支持的投资公司那里获得了一笔未
披露数额的投资。
在具有潜在军事应用的尖端技术领域,中国企业已经成为美国初创公司的重要投资者。
这些初创公司中有些制造航天器火箭发动机、自主海军船舶传感器,有些制造可以给战
斗机驾驶舱印刷柔性屏幕的设备。这些中国投资者中有很多都隶属于国企,或者是和中
国领导人有联系。
这些交易在华盛顿敲响了警钟。国防部(Department of Defense)委托制作的一份新白
皮书声称,北京正在鼓励那些和中国政府关系密切的企业,把资金投入到人工智能和机
器人等关键技术领域的美国初创公司,以推动中国的军事能力和经济发展。
三位不愿具名的知情人士说,这本白皮书本周分发到了特朗普政府的高级别官员手中,
它总结说,美国政府本来应该保护这些潜在的关键技术,但目前的控制力度还不够。

周一,一工会领导人称,Aveos Fleet Performance Inc.公司,原名Aveos Fleet Performance Inc.,计划裁员1千逾人。
温尼伯(Winnipeg)国际机械师及航空工作者协会714分会(Local 714 of the International Association of Machinists and Aerospace Workers)主席Lorne Hammerberg称,此次裁员人数占Aveos全国劳工数的近1/3。
Hammerberg称,温尼伯将被裁员356人,蒙特利尔(Montreal)455人,温哥华220人。
周一晚上,Hammerberg在采访中说,“想到过去我们的雇员做出的妥协,此次裁员很是令人失望。”
09年12月份时,Aveos还曾称,外界对公司裁员的预测夸大了,因为很多裁员都是暂时的。
Hammerberg预测,在计划裁掉的1,031人中,有203人属于长期被裁。

不论是哪个国家的大学教育都离不开专业上的分野,而在现代社会中不同专业的大学毕业生不仅在未来职业上所走的道路不同,其毕业的起薪和职业生涯的收入状况也会有很大差异。根据美国薪水衡量网站所做的 “2010年美国大学毕业生薪水报告”,工程专业在所有大学专业中(不包括医学和法学专业)依然是“钱途”中的姣姣者。
在以下这些大学专业中,石油工程、航空和航天工程、化学工程、电机工程、核工程、应用数学和生物医学工程,本科毕业生的起薪都不低,而且在大学毕业生职业生涯中期的中位年薪均在10万美元以上。以下是美国大学最有“前途”的50个专业毕业生收入状况。这些数据来自对美国999所大学毕业生的综合调查和统计,毕业生起薪为 2009年的数据,毕业生职业生涯中位年薪是指毕业生在其专业领域工作10年以上的收入。
本科毕业生职业生涯中期中位年薪10万美元以上的专业
1.石油工程(Petroleum Engineering),大学本科毕业生中位年薪为93,000美元,大学本科毕业生职业生涯中期中位年薪为157,000美元。

加拿大航空公司(Air Canada)顾客服务员周五复工﹐罢工行动暂时平息﹐但下一波工潮仍在酝酿﹐因为加航仍与几个重要雇员组织谈判合约。
地勤职员为退休金和薪金罢工﹐空中服务员﹑机师﹑机械师和行李员快要谈判的合约﹐预计也会提出同样问题。
加拿大汽车工人工会(Canadian Auto Workers)代表的员工罢工3天后﹐在周五复工。劳工部长雷特(Lisa Raitt)准备复工法案后不久﹐加航劳资双方即在周四达成协议。
加航下一轮谈判对象是6800名空中服务员的代表工会﹐联邦调停员大概下周委任﹐与工会协调。
工会表示﹐空中服务员到8月中可以合法罢工。但加航称﹐他们在9月前都不可能合法罢工。
空服员罢工服务更受影响
加航地勤职员罢工﹐公司仍能维持航班服务﹐但有延误。如果空中服务员罢工﹐服务就会大受影响。
代表机械师及行李员的国际机械师及航天工人协会(International Association of Machinists and Aerospace Workers)7月重返谈判桌﹐加航及机师也会重返谈判桌﹐因为工会会员今年较早时否决临时协议。

近一段时期,加拿大北极地区的安全利益问题在地理条件变化等因素的推动下重新浮现在公众面前,并且其未来走向依然无法预知。国际社会对日益紧缺的资源的争夺早已开始在北极地区上演,加拿大北极安全问题专家罗布休伯特(Rob Huebert)就曾说过:“全球气候变化、资源价格上涨、国际政治斗争以及不断取得的技术进步使北极地区的开发难度降低,因而也使其更加富有吸引力。”据《北极气候影响评估报告》(Arctic Climate Impact Assessment)预测,气候变化将会导致北极地区温度上升,北极海冰数量在每年夏季末期也会有所降低。这些条件促使北极日益成为国际活动的开放地区,被巨大经济利益前景所吸引的各种外部势力也越来越多地参与北极事务。因此,加拿大保卫北方地区国家主权和安全的能力将受到更加严峻的考验。资源竞争、季节性航道以及移民问题都增加了北方地区爆发冲突的可能性,此外加拿大与其环北极圈邻国悬而未决的边界争端因北极问题的国际化而更加复杂,而且这还有可能对北方地区的人口结构产生巨大影响。

韩国首尔——周三早上,朝鲜发射了一枚远程火箭,似乎达到了遥远的菲律宾。对该国未经考验的年轻新领导人金正恩(Kim Jong-un)而言,这明显是一场胜利。此外,此次发射还使朝鲜向掌握在洲际弹道导弹上装载核弹头技术的目标迈进了一步。
此举表明, 新任领导人金正恩(Kim Jong-un)的朝鲜政府正在加紧推进相关工作,力图掌握在洲际弹道导弹上装载核弹头所需的技术。
位于朝鲜平安北道铁山县的西海卫星发射场。
朝鲜最高领导人金正恩不顾联合国安理会实施更多制裁的可能,于周三发射了一枚火箭。
韩国国防部发言人称,周三早上,“银河3号”(Unha-3)火箭从位于朝鲜西海岸靠近中国的东仓里的西海卫星发射场(Sohae Satellite Launching Station)发射升空。
这名发言人说,“这就是我们目前可以确认的全部内容。”该发言人要求在韩国政府发布正式公告之前保持匿名。
还不能马上知道,这次发射是否达到了朝鲜宣称的将火箭送入轨道的目标。
朝鲜曾称,其三级火箭将搭载一颗名为“光明星3号”(Kwangmyongsong-3)的地球观测卫星,并称此举是在行使其在太空进行和平活动的权利。

洛杉矶警方赶到现场并封锁UCLA校园。(美联社图)
加州大学洛杉矶分校(University of California, Los Angeles,简称UCLA)于周三(6月1日)近早晨10点发生枪击案,随后整个校园被封锁。
UCLA警方发言人詹姆斯·赫伦(James Herren)于中午(约12点)宣布校园已经安全,并证实有两名成年男性死亡,这是一起枪击自杀案——枪手杀死一人后自杀。当地新闻电视台KTLA报道称,警方根据枪手留下的一张字条确定这是一起枪击自杀案。
据《侨报》记者章宁现场报道,一位不愿意透露姓名的教授称,枪击案发生在办公室,一名叫威廉·克卢格(William Klug)的教授被枪杀,周围办公室的同事听到枪声后非常震惊,有名教授反应冷静,直接将走道门锁上,使得嫌犯无法逃脱,于是开枪自尽。因事发突然,事实不明,为防止出现其它意外,及保护就在附近的医院,出动了大批警务人员。该教授还表示,“已经很明确嫌犯身份,有说3名、4名凶手的说法并不属实,实际情况就是两名死者,一名被枪杀,一名自杀。”根据UCLA官网显示,克卢格在机械和航空航天工程(Mechanical and Aeros... 阅读全帖

消息人士澳门国际防备研究所的Antony Wong Dong说:定48架,是应俄罗斯的要求,
因为俄国认为一型战机只有造40架以上,才有钱赚,在去年的苏33交易中,俄国也
是这样要求中国的。
其文中,也提到Andrei Chang---即著名的平可夫大师,他对南华早报记者说:"In
fact, Russia has sold many AL-31F engines, which could be used in both the
Su-33 and J-15, to China already,"
原文如下:
Russia has signalled its intention to sell advanced fourth-generation Su-35
fighter jets and other sophisticated weapons to China, a reversal of its
previous policy of denying Beijing access to such equipment, military and
diplomatic experts ... 阅读全帖

The Decline and Fall of the American Empire
By Alfred W. McCoy
December 11, 2010 "The Nation" - - A soft landing for America 40 years from
now? Don’t bet on it. The demise of the United States as the global
superpower could come far more quickly than anyone imagines. If Washington
is dreaming of 2040 or 2050 as the end of the American Century, a more
realistic asses... 阅读全帖

这文章我昨天贴过了。。这段时间米犹的舆论机器很忙。。在nytimes和economist上“
报道”中国的文章是一个接着一个。。不过就这篇文章来说下面有几个评论说的很好。
。一个是指出美国是世界上最大的贸易保护者对农业等各种产业补贴数额最大的就是美
国。。还有一个评论就指出我们都是合法引进花钱买的技术。。不过看下面大部分的评
论米犹煽动仇恨的目的还是达到了
The article fails to mention, or misleads, on two important factors.
One, for almost all serious technology, China pays real money for that
transfer of know-how. For e.g., with the high-speed trains, China paid
Kawasaki, Alstom, Siemens and Bombardier more than 3 billion dollars for the
technology and training.

认为法国只是时尚中心那只能说明你无知得厉害。世界上只有三个真正的国际都市,那
就是纽约巴黎伦敦,其他都是自封的,跟这三个城市不是一个档次。什么柏林东京香港
都要靠边站。
你除了巴黎没听过法国别的地方,再次反映你的无知。

我这个aerospace反正被无尽地鄙视了。这厮也许接触过常微(估计偏微是啥都不知道
),估计也就是背背通解特解那种人了。火箭推进问题和卫星变轨问题是学常微入门时
都要接触的问题。还活塞运动了,搞笑.我说他们连这些都不懂,还是不要去怀疑了

来自主题: Military版 - China's spying seeks secret US info
He had been a seemingly all-American, clean-cut guy: No criminal record.
Engaged to be married. A job teaching English overseas. In letters to the
judge, loved ones described the 29-year-old Midwesterner as honest and
caring — a good citizen. His fiancee called him "Mr. Patriot."
Such descriptions make the one that culminated in the courtroom all the more
baffling: Glenn Shriver was also a spy recruit for China. He took $70,000
from individuals he knew to be Chinese intelligence officers to try ... 阅读全帖
