  MIPS64 RISC 28 nm the benchmarks shows it is bottom 2nd laptop from BYD with 14nm quad-core 3A4000 CPU. Longsoon claims the CPU is 100% faster than the previous generation 3A3000 and is comparable in performance to AMD's "Excavator" cores used in the A8-7680 Godavari architecture. Of course, this demonstrates how far behind Longsoon is from TSMC and Intel in performance, speed, and efficiency of its latest node. benchmarks compare CSDN

Samples would then be transferred to specially developed facilities for handling, analyzing, and storing the lunar material.    嫦娥五号任务计划实现三大工程目标： 一是突破窄窗口多轨道装订发射、月面自动采样与封装、月面起飞、月球轨道交会对接、月球样品储存等关键技术，提升我国航天技术水平; 二是实现我国首次地外天体自动采样返回，推动我国科学技术重大进步; 三是完善探月工程体系，为我国未来开展载人登月与深空探测积累重要的人

  There are two principal types of radar system used for ATC, namely primary surveillance radar (PSR) and secondary surveillance radar (SSR). A PSR transmits radar pulses and detects the reflected signals from the aircraft concerned. It provides information on the range and bearing of aircraft in the form of a target blip on the radar screen.  An SSR provides information on the position, altitude and identity of aircraft in the form of target label on the radar screen. It does so by transmitting interrogation signals to trigger the transponder on board an aircraft, which in turn transmits special coded signals back to the SSR to provide the concerned information. Thus, effective operation of an SSR is subject to the availability and proper functioning of the aircraft’s transponders. Not all aircraft have transponders. Some military aircraft, for instance, do not.   A PSR, on the other hand, does not rely on any transponder. To provide an adequate radar picture with a continuous display

You can see some strange big white rectangular hoardings when you are hiking along wilson trail 3, one is facing north east and the other south west. The boards were often tagged as 'former aviation reflector' Many said that it is for aircrafts, during foggy weather, when visibility is low. Common belief is that  they bounce back radio waves. Some say it is microwave antenna However, when you think more carefully, the shape of it do not reflect the waves back to aircraft as they should, it is rather a wave spreader than a reflector. What is it? If it is a reflector , it should look like a corner of a square box, or called as corner reflector.   It seems to be erected for the Hong Kong airport, likely be the previous Kai Tak airport. It could be part of the transponder system for air traffic control transponder or as special purpose secondary surveillance radar (SSR), or part of the SSR system. The electronics may have been removed after the Kai Tak airport was closed and /or su

Most says they also let more coffee oil into cup ( wrt paper filter) OTOH, some minor nuances might also be filtered out too, and cause less complexity/ monotonic question: will too small hole size also blocks coffee oils?   coffeeastra

 2020年 9月12日 中國的「快舟」運載火箭繼七月之後，再次發射衛星失敗。當局通報，昨天下午一時，甘肅酒泉衛星發射中心利用「快舟一號甲」運載火箭發射「吉林一號」高分02C衞星，但火箭飛行出現異常，發射失利，正分析具體原因。「快舟一號」是由中國航天科工集團研製的全固體燃料小型運載火箭，全長二十米，起飛重量三十噸，二○一三年投入使用。   Jilin-1 Gaofen (‘high resolution’) 02C optical Earth observation satellite. The satellite was understood to have 0.76-meter resolution capabilities with a swath width of 40 kilometers.   The Kuaizhou-1A, understood to be derived from missile technology, consists of three solid stages and a liquid propellant upper stage, and is capable of lofting a 200-kilogram payload into a 700-kilometer sun-synchronous orbit (SSO). The Kuaizhou-1 launcher, developed by China Aerospace Science and Technology Corporation (CASIC), is a small, solid fueled launch vehicle, which is possibly based on the road mobile DF-21 IRBM with two additional upper stages.  kknews global security   skyrocket  Norbert Brugge
