The principal features of the ALICE Central Trigger Processor are presented, as described in the draft User Requirement Document currently under discussion.

We consider the weighted version of the Tron game on graphs where two players, Alice and Bob, each build their own path by claiming one vertex at a time, starting with Alice. The vertices carry non-negative weights that sum up to 1 and either player tries to claim a path with larger total weight than the opponent. We show that if the graph is a tree then Alice can always ensure to get at most 1...

Communication and Third Parties: Costs, Cues, and Confidentiality by Krishnan Eswaran Doctor of Philosophy in Engineering—Electrical Engineering and Computer Sciences and the Designated Emphasis in Communication, Computation, and Statistics University of California, Berkeley Professor Michael Gastpar, Chair This thesis tells the story of Alice and Bob, who wish to share information. However, Al...

Introduced in 2009 in [6] bitcoin is one of the first decentralized currency. It’s called crypto-currency, since it uses cryptography to secure transactions and assets. Bitcoin operation is based on so-called public ledgers that can be shortly described as follows. Assume there are two parties Alice and Bob (as usual), such that Alice wants to buy something from Bob. Assume they both have walle...

In this paper we consider a new and efficient optimistic nonrepudiation protocol. In a non-repudiation protocol, during which Alice wants to transmit a message to Bob, Alice has to send a non-repudiation of origin evidence to Bob (attesting that Alice is at the origin of the transmitted message), and Bob has to send a non-repudiation of receipt evidence to Alice (attesting Bob’s receipt of the ...

The game. Alice and Bob decide to play the following infinite game on the real number line. A subset S of the unit interval [0, 1] is fixed, and then Alice and Bob alternate playing real numbers. Alice moves first, choosing any real number a1 strictly between 0 and 1. Bob then chooses any real number b1 strictly between a1 and 1. On each subsequent turn, the players must choose a point strictly...
