Hello!! It's Joseph

Mission:  The Transiting Exoplanet Survey Satellite (TESS) is an full sky mapping Explorer-class mission, dedicated to finding planets around bright, nearby stars so that more detailed follow-up studies can be done.   specification The detector assembly in each camera consists of a focal plane CCD array and associated electronics. Each CCD array contains four back-illuminated MIT/Lincoln Laboratory CCID-80 devices. The 100um deep-depletion, frame-transfer CCDs consist of a 2048 x 2048 imaging array and a 2048 x 2048 frame-store region (for rapid shutter-less readout 4 ms) with 15 x 15 micron pixels. The four CCDs in each array are separated by 2mm and create an effective 4096 x 4096 pixel detector that is operated at -75 degrees C to reduce dark current. The detectors are read out at 625 kHz with <10 e- read noise. The detector electronics consist of two compact double-sided printed circuit boards seated beneath the CCD focal plane. The el

Mi band one ( First gen ) plastic package removed, and uncoiled: so it is a lithium polymer type battery. 3.8V 0.17 Wh 0.17 / 3.8 = 45 mAh capacity Mi Band 2 ( 2nd gen ) again a lithium polymer battery 3.7V, 0.17Wh, 45 mAh capacity So despite a newer generation, the battery remains same. The major difference is the on UI. Generation One use 4 dot size LED Generationt Two use dot matrix OLED

From BoldJava: ^ Preheat unit with hopper in to 175C. ^ Pre-measure 230grams ^ Hit E stop and move like the wind ^ Use dual settings. a. High grown or dense beans: 248C into the first crack plus 45 seconds. Then turn down to 243C until 2:30 minutes past initial crack of first crack (try to stay out of 2nd crack). I call this a full city roast and is my starting point for working on a new bean. I can shorten/lengthen based on cupping results. Most beans finish between 12:45 and 14:00 minutes. b. Brazilians, some Indonesians, intermediate elevation beans: 243C/237C, profiled above c. Kona and Caribbean beans: 237C/232C , profiled above I end the roasts with an E stop and cool my beans externally. My current is a steady 120 (variac controlled). My assumption is that you have 220V so trust that the profiles can be superimposed onto your unit. From John Despres: The harder, more dense beans that are typically grown over 5000 feet need a higher initial heat and less

For fine grinding starting from 220 grit and finer, the normal 1/3D stroke used is shown in Fig 8. the mirror is centered over the tool and the stroke is a W-type stroke with a total lateral amplitude of ¼D (i.e. 1.8 cm on either side of the centre for a 15 cm mirror) and an up and down amplitude of about 1/3D (i.e. about 2.5 cm up, 2.5 cm down for a 15 cm mirror). It should be 1/3D on the average; some strokes should be a little shorter and some a little longer. No attempt should be made to make the strokes uniformly 1/3D in amplitude. The 120 0 rotations of the blank above and the 45 0 rotations of the blank below are of course continued. the wet now lasts longer, say for 4 or 5 minutes. At the completion of a wet the mirror and tool are cleaned as before and a fresh charge used. Shankar

Regarding the maintenance of expressways, sign lighting by nightly searchlight is a concern for light hazards and traffic safety. I would like to ask for appropriate guidance to related areas, thank you. Astronomical observation, science education: Astronomical observation requires a dark night sky. Japan boasts one of the world's leading campaigns and achievements in citizen (amateur) astronomical activities, and specialized astronomers at universities, research institutes and science educational facilities throughout the country are conducting advanced research to capture weak light from space I am doing big scientific achievements. At elementary and secondary schools, observation of stars and astronomical observations are conducted as part of science education.

The FreeRTOS kernel was originally developed by Richard Barry around 2003, and was later developed and maintained by Richard's company, Real Time Engineers Ltd. FreeRTOS was a runaway success, and in 2017 Real Time Engineers Ltd. passed stewardship of the FreeRTOS project to Amazon Web Services (AWS). Richard continues to work on FreeRTOS as part of an AWS team.

The AIY Vision Kit is a $45 add-on board that attaches to a Raspberry Pi Zero with a Pi 2 camera. The board includes a Vision Processing Unit (VPU) chip that runs Tensor Flow image processing graphs super efficiently. The kit comes with a bunch of examples out of the box, but to actually see what the camera see’s you need to plug the HDMI into a monitor. That’s not very useful when you want to put your battery powered kit in a remote location. And while it is nice that the rig does not require any Internet connectivity, that misses out on a lot of the fun applications. Vision Bonnet The Bonnet is just a small Pi Hat that attaches to the Pi Zero GPIO header. As one of the Googlers on the project was nice enough to explain , the Vision Bonnet reads directly from the Pi Camera via the standard Pi camera flex  cable that passes through it. This means your other process have full access to the Pi Camera while it is running your code. It also means it does not use us

The situation room, 60 minutes  Australia youtube Former Senior Investigator with the Transportation Safety Board of Canada, Larry Vance, told 60 Minutes he was confident he knows what happened to the aircraft. "I think the general public can take comfort in the fact that there is a growing consensus on the plane's final moments," he said. Mr Vance said the pilot "was killing himself" and took the aircraft to the most remote place possible so it would "disappear". "Unfortunately, he was [also] killing everybody else on board, and he did it deliberately," he said. "He was taking it to a predestination, some place that he had planned to take it, and he flew that six hours to get it there." Mr Vance said he envisioned the plane on the bottom of the ocean, with the fuselage in one piece and the left wing still on. "The right wing may be off, the engines are separate, but you basically have four pieces of aeropl
