Web scraping or Web crawling
HTML >> content of web page
CSS >> design of web page
Javascript >> for web page action
HTML?? HyperText Markup Language <> tag 으로 구성됨(tree 구조)
Static Web Page Scraping >> use Beautifulsoup (find base on tag and attributes)
Dynamic Web Page Scraping>> have to use Selenium (not enough with BS)
Selenium >> web page 조작 가능 (like clicking)
API >> waiter of restaurant >> receive from A and refer to
In ground wave propagation, radio waves travel along the surface of the Earth, following the curvature of the planet. Freq Range: 30 kHz to 300 kHz (Low Freq). Key Points: Travels along the ground. Strongly attenuated by terrain, trees, buildings, etc. Limited to short distances (few hundred km). APPS: AM radio (MW band). Navigation systems & military communication.In sky wave propagation, radio waves R transmitted towards the ionosphere, which reflects or refracts them back to Earth. Freq Range:
Mesoamérica:
Zona geográfica y cultural que incluye parte de México y Centroamérica.
Características: agricultura (maíz), politeísmo, escritura jeroglífica, calendario.
Cosmovisión:
Relación entre dioses, naturaleza y humanos.
Ciclicidad del tiempo y sacrificios como ofrenda a los dioses.
Aportaciones de 3 culturas:
Olmeca: calendario, escritura, cabezas colosales.
Maya: sistema numérico con el cero, astronomía, arquitectura avanzada.
Teken f(x) = a^x of log_a(x)
Horizontale lijntest → inverteerbaar?
Inverse: y = a^x ⇔ x = logₐ(y)
Uit tabel of grafiek → herken exponentieel of logaritmisch
Zoek a via punt:
Exponentieel: f(x) = a^x
Logaritmisch: f(x) = logₐ(x) → a^y = x
Zelfde grondtal? → vergelijk exponenten
Anders: log aan beide zijden
Vergeet bestaansvoorwaarden (bv. log > 0) niet

Chemical vapour deposition, a hybrid method using chemicals in vapour phase is conventionally used to obtain coatings of a variety of inorganic or organic materials.It is widely used in industry because of relatively simple instrumentation, ease of processing, possibility of depositing different types of materials and economical viability.Under certain deposition conditions nanocrystalline films or single crystalline films are possible. There are many variants of CVD like Metallo Organic CVD (MOCVD)
