چکیده
Codes Description of C Nonsingular C injective – i.e. ∀x, x′ ∈ X , x 6= x′ =⇒ C(x) = C(x′) Uniquely Decodable The extension the code is nonsingular. Prefix/Instantaneous/Self-punctuating No code word prefixes another: for all distinct x′, x′′ ∈ X , C(x′) does not start with C(x′′) We illustrate this below with the following example for the symbols {a, b, c, d} taken from Chapter 5 in Cover and Thomas.

2 Finishing the Description of Fusion Trees 2.1 Motivation 2.2 the Problem -fixed-universe Successor 2.3 Overview of Fusion Trees
More generally, the goal of fusion trees is to support the operations insert(x), delete(x), successor(x) and predecessor(x) in o(lgn) time on a transdichotomous RAM. The transdichotomous RAM model of computation was intrdouced in Lecture 2 (Feb. 12, 2003). The data-structure problem defined by these four operations is called the fixed-universe successor problem which was introduced in Lecture 1...

متن کاملThe Thermodynamics of Quarks and Gluons
This is an introduction to the study of strongly interacting matter. We survey its different possible states and discuss the transition from hadronic matter to a plasma of deconfined quarks and gluons. Following this, we summarize the results provided by lattice QCD finite temperature and density, and then investigate the nature of the deconfinement transition. Finally we give a schematic overv...

متن کاملQuantum Computing: Lecture Notes
Preface These lecture notes were formed in small chunks during my " Quantum computing " course at the University of Amsterdam, Feb-May 2011, and compiled into one text thereafter. Each chapter was covered in a lecture of 2 × 45 minutes, with an additional 45-minute lecture for exercises and homework. The first half of the course (Chapters 1–7) covers quantum algorithms, the second half covers q...
