Frequentia






Tres frequentiae. Prima lux frequentiam 0.5 Hz habet, hoc est "0.5 per secundum" micat, vel semel per duo secundos. Frequentia secundae lucis est 1 Hz, hoc est semel per secundum micat. Tertia autem frequentia 2 Hz habet, quae bis per secundum micat. T (sc. "tempus") est intervallum inter fulgores.


Frequentia aetate Ciceronis id solum significabat, quotiens locum quendam visitaret vel multitudo vel turba; et solum vocabulum crebritas ea aetate significabat, quotiens res quaedam repeteretur. Sed hodie vocabulum frequentia etiam significat in re technica, quotiens in temporis momento res quaedam repetatur, praesertim cum de aliqua re physica agitur, quae constanter se repetit.[1] Exempli causa res, quae continue se repetit undeciens in temporis secundo, dicitur frequentiam undeciens in secundo habere. More aetatis Newtoni idem possumus dicere "undeciens per secundum" vel "11 per secundum".[2] In Systemate Unitatium Internationali, unitas frequentiae est Hertzium (symbolum: Hz), et res quae se repetit undeciens in temporis secundo dicitur frequentiam 11 Hz habere.

Updating UILabel text programmatically using a function

Image
0 so I am trying to update the UIlabel text using a func. I have seen few other questions like mine and I tried their method but it doesn't work. fun returns no value when used in the UIlabel. I have shown my code below.It has to be noted that when I use the function in viewdidload I can retrieve the data. lazy var name: UILabel = { let lb = UILabel() lb.text? = getthename() lb.lineBreakMode = NSLineBreakMode.byWordWrapping lb.textColor = .mainGreen lb.textAlignment = .left lb.font = UIFont.boldSystemFont(ofSize:12.0) return lb }() func getthename() -> String { var wins : String = "" let ud = (Auth.auth().currentUser?.uid) self.ref = Database.database().reference() self.ref.child("Users").child(ud!).observeSingleEvent(of: .value, with: {(snapshot) in...

Cloud Functions - OpenCV Videocapture Read method fails for larger files from cloud storage

Image
0 I created a cloud function to read a video file from cloud storage and read frames and create an image for each frame. This function works for small files which is 1-2 MB, However, this method fails while reading larger file 130 MB. import cv2 from google.cloud import storage vidcap = cv2.VideoCapture("https://storage.googleapis.com/[bucker_name]/[filename.mp4]") if vidcap.isOpened(): vidcap.open("https://storage.googleapis.com/[bucker_name]/[filename.mp4]") success,image = vidcap.read() print(success) Expected the print will return true and an image will hold an image of a first frame. python-3.x function opencv cloud share | improve this question ...
