SIMULATIONS OF MULTIPACTING IN THE CATHODE STALK AND FPC OF 112 MHZ SUPERCONDUCTING ELECTRON GUN*
"... Abstract A 112 MHz superconducting quarter-wave resonator electron gun will be used as the injector of the Coherent Electron Cooling (CEC) proof-of-principle experiment at BNL. Furthermore, this electron gun can be used for testing of the performance of various high quantum efficiency photocathodes ..."

photocathodes. In a previous paper, we presented the design of the cathode stalks and a Fundamental Power Coupler (FPC). In this paper we present updated designs of the cathode stalk and FPC. Multipacting in the cathode stalk and FPC was simulated using three different codes. All simulation results show
The FPC Double-Precision Floating-Point Compression Algorithm and its Implementation
"... This document provides detailed information about the design and our C implementation of the FPC compression algorithm. It is meant as an addendum to and contains excerpts from two other publications about FPC [1], [2]. Please refer to these publications for additional information such as performanc ..."

, if the predicted and the true value are close, the xor result has many leading zeros. FPC then counts the number of leading zero bytes, encodes the count in a three-bit value, and concatenates it with a single bit that specifies which of the two predictions was used. The resulting four-bit code and the nonzero
The Interpersonal Process Code (IPC)
, 1991
"... this research, initiated by Gerald Patterson and John Reid, was to understand the contribution of family interaction to the development of childhood antisocial behavior (Patterson, 1982; Patterson, Reid & Dishion, in press; Reid & Patterson, 1989), and to design effective intervention progr ..."

programs. The most recent observation tool used to study family interaction was the Family Process Code (FPC) (Dishion et al, 1983). This code was heavily influenced by the Family Interaction Coding System (FICS) (Reid, 1978). The FICS code worked well as an observational measure of treatment outcome
User Manual FPC AS A MATLAB Solver for ℓ1-Regularized Least Squares Problems
"... FPC AS stands for fixed-point continuation and active set. It solves the ℓ1-regularized minimization problem (1.1) min x∈R n ψµ(x): = µ‖x‖1 + 1 2 ‖Ax − b‖2 M, where x ∈ R n, A ∈ R m×n, M ∈ R m×m, and b ∈ R m, and µ> 0 is the regularization parameter. It is based upon the active-set algorithm with ..."

with a continuation strategy described in [1, 2]. FPC AS is a successor of FPC [3]. While FPC AS still performs shrinkage iterations and continuation as its predecessor, most of the code has been rewritten. Compared to FPC, which has good performance on large-scale problems with highly sparse solutions
A fast algorithm for sparse reconstruction based on shrinkage, subspace optimization and continuation
- SIAM Journal on Scientific Computing
, 2010
"... Abstract. We propose a fast algorithm for solving the ℓ1-regularized minimization problem minx∈R n µ‖x‖1 + ‖Ax − b ‖ 2 2 for recovering sparse solutions to an undetermined system of linear equations Ax = b. The algorithm is divided into two stages that are performed repeatedly. In the first stage a ..."

. The resulting subspace problem, which involves the minimization of a smaller and smooth quadratic function, is solved in the second phase. Our code FPC AS embeds this basic two-stage algorithm in a continuation (homotopy) approach by assigning a decreasing sequence of values to µ. This code exhibits state
Recursive Types in Games: Axiomatics and Process Representation (Extended Abstract)
- IN PROCEEDINGS O.F LICS'98. IEEE COMPUTER
, 1998
"... This paper presents two basic results on game-based semantics of FPC, a metalanguage with sums, products, exponentials and recursive types. First we give an axiomatic account of the category of games G introduced in [15], offering a fundamental structural analysis of the category as well as a transp ..."

However, we advance their representation by introducing semantically well-founded optimisation techniques; we also exte...
A graph-theoretical approach to the selection of the minimum tiling path from a physical map
- IEEE/ACM Trans. Comput. Biol. Bioinform
, 2013
"... Abstract—The problem of computing the minimum tiling path (MTP) from a set of clones arranged in a physical map is a cornerstone of hierarchical (clone-by-clone) genome sequencing projects. We formulate this problem in a graph theoretical framework, and then solve by a combination of minimum hitting ..."

Implementation Oriented Phase based IRIS Recognition

In this technique phase component present in Two dimensional (2D) Discrete Fourier Transform (DFT) of given images are used to determine similarity between two images.

code (2D FPC) is used to represent iris information. Instead of storing whole iris image, only 2D FPC is stored in the database which reduces size of required database significantly. This method is evaluated with CASIA iris image database (version 1.0).
