Marine VHF radio - Wikipedia

Marine VHF radio refers to the radio frequency range between 156 and 174 MHz, inclusive. The "VHF" signifies the very high frequency of the range. In the official language of the International Telecommunication Union the band is called the VHF maritime mobile band. In some countries additional channels are used, such as[1] the L and F channels for leisure and fishing vessels in the Nordic countries (at 155.5–155.825 MHz).

Digital signatures are used world wide to verify the authenticity of messages and confirm that they have not been altered in transmission. The Digital Signature Algorithm (DSA) is a Digital Signature Standard for the Federal Information Processing Standard and uses public key cryptography. The Elliptic Curve Digital Signature Algorithm (ECDSA) is a version of DSA using elliptic curves. In this paper, I will introduce ECDSA and discuss its key generation, signing, and verifying procedures. Then, I will compare this algorithm to the RSA digital signature algorithm and discuss its various advantages and drawbacks. Finally, I will discuss the security of ECDSA and attacks that can break it.

When writing a ray tracer, sooner or later you’ll stumble on the problem of reflection and transmission. To visualize mirror-like objects, you need to reflect your viewing rays. To simulate a lens, you need refraction. While most people have heard of the law of reflection and Snell’s law, they often have difficulties with actually calculating the direction vectors of the reflected and refracted rays. In the following pages, exactly this problem will be addressed. As a bonus, some Fresnel equations will be added to the mix, so you can actually calculate how much light is reflected or transmitted (yes, it’s possible). At the end, you’ll have some usable formulas to use in your latest ray tracer.
