3 Chapter one

4 How do you read a waterspout F mile winds.not much damage F mile winds.simple damage F mile winds.moderate damage F mile winds.severe damage F mile winds.davesting damage F mile winds. You hope no one is around.

5 How are waterspouts made Waterspouts are sometimes made after a hurricane Waterspouts are a bunch condensed water droplets. Waterspouts are vortexes. Wind helps Waterspouts navigate through a coast.

6 Are waterspouts helpful No and yes. Water spouts are not helpful when they rip,rip,rip Up towns and cities that are by a coast. Waterspouts are helpful when they Throw fish onto the shore. But still they hurt more then they help.

11 How is a whirlpool started Whirlpools at sea are caused by the meeting of opposing currents and tides, by ocean currents striking offshore rocks and other coastal configurations, and by the force of wind acting upon water. Irregularities in basin and channel bottoms usually cause whirlpools in rivers and lakes. Whirlpools in the open seas are giant suctionless eddies, such as the Sargasso Sea in the Atlantic ocean, were sometimes becalmed in them and were held fast in their centers or were swept by the slowly rotating currents against rugged coasts. Whirlpools with a strong vortical motion, on the other hand, can become very violent and are capable of sucking boats into their rapidly down- spiraling cavities. Noted whirlpools include the Charybdis in the Strait of Messina between mainland Italy and the island of Sicily, the Maelstrom, or Moskenstraumen, in the Lofoten Islands off Norway, and the Whirlpool Rapids below Niagara Falls.

12 What Is a Whirlpool WHIRLPOOL is a cryptographic hash function designed by Vincent Rijmen and Paulo S. L. M. Barreto. The hash has been recommended by the NESSIE project. It has also been adopted by the International Organization for Standardization (ISO) and the International Electrotechnical cryptographic hash functionVincent RijmenPaulo S. L. M.

WHIRLPOOL is a Miyaguchi-Preneel construction based on a substantially modified Advanced Encryption Standard (AES). Given a message less than bits in length, it returns a 512-bit message digest.

It may be used free of charge for any purpose. The reference implementations are in the public domain." The algorithm is named after the Whirlpool Galaxy in Canes Venatici. Whirlpool GalaxyCanes VenaticiWhirlpool GalaxyCanes Venatici [edit] edit WHIRLPOOL hashes The WHIRLPOOL algorithm has undergone two revisions since its original 2000 specification. In the first revision in 2001, the s-box was changed from a randomly generated one with good cryptographic properties to one which has better cryptographic properties and is easier to implement in hardware. In the second revision (2003), the diffusion matrix was changed s-box s-box2003 People incorporating WHIRLPOOL will most likely use the most recent revision of WHIRLPOOL; while there are no known security weaknesses in earlier versions of WHIRLPOOL, the most recent revision has better hardware implementation efficiency characteristics, and is also likely to be more secure. As mentioned earlier, it is also the version adopted in the ISO/IEC international standard. international standardinternational standard The original WHIRLPOOL will be called WHIRLPOOL-0 and the first revision of WHIRLPOOL will be called WHIRLPOOL-1 in the following test vectors. The 512-bit (64-byte) WHIRLPOOL hashes (also termed message digests) are typically represented as 128-digit hexadecimal numbers. The following demonstrates a 43-byte ASCII input and the corresponding WHIRLPOOL hashes: hexadecimal ASCIIhexadecimal ASCII
