xl2tpd a Layer 2 Tunneling Protocol (L2TP) daemon. It supports IPsec SA reference tracking, which enables the IPsec stacks to support multiple l2tp clients behind the same NAT router and multiple l2tp clients on the same internal IP address. It is a fork of "l2tpd".
Release focus: Minor feature enhancements
Changes:
Support for passwordfd, a workaround for some Cisco routers, and extended logging.
Carrier-phase synchronization can be approached in a
general manner by estimating the multiplicative distortion (MD) to which
a baseband received signal in an RF or coherent optical transmission
system is subjected. This paper presents a unified modeling and
estimation of the MD in finite-alphabet digital communication systems. A
simple form of MD is the camer phase exp GO) which has to be estimated
and compensated for in a coherent receiver. A more general case with
fading must, however, allow for amplitude as well as phase variations of
the MD.
We assume a state-variable model for the MD and generally obtain a
nonlinear estimation problem with additional randomly-varying system
parameters such as received signal power, frequency offset, and Doppler
spread. An extended Kalman filter is then applied as a near-optimal
solution to the adaptive MD and channel parameter estimation problem.
Examples are given to show the use and some advantages of this scheme.
We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

VxWorks 6.6 BSP開發執導
This document describes, in general terms, the elements that make up a board
support package [BSP], the requirements for a VxWorks BSP, and the general
behavior of a BSP during the boot process. This document outlines the steps
needed to port an existing BSP to a new hardware platform or to write a new
VxWorks BSP for custom hardware using a reference BSP or template BSP as a
starting point. It provides hints and tips for debugging a BSP and solving common
BSP development problems. It also provides information on the BSP validation test
suite [BSP VTS] that is used to assess the functionality of a VxWorks BSP.
This book is for systems architects
who are interested in building security into their applications. The book is designed to
be useful to architects in three ways: as an introduction to security architecture, as a
handbook on security issues for architecture review, and as a catalog of designs to look
for within a security product.
) Compression using huffman code
-with a number of bits k per code word
-provide huffman table
Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code table for encoding a source symbol. The table is derived in a particular way based on the estimated probability of occurrence for each possible value of the source symbol .Huffman coding uses a specific method for representing each symbol, resulting in a prefix code that expresses the most common characters using shorter strings of bits than those used for less common source symbols.The Huffman coding is a procedure to generate a binary code tree.
A java application - processing which can be downloaded free from processing.org
Here it uses a free library - OpenCV - made by intel. .. to convert all the pixels in an image - in fact in a movie - a capture from the webcam. If the color of a pixel is "higher" comparing to a threshold it turns black - otherwise it becomes white.
The potential of solving real-time demanding industrial applications, using vision-based
algorithms, drastically grew due to an increasing availability of computational power.
In this thesis a novel real-time, vision-based Blackjack analysis system is presented. The
embedding of the vision algorithms in a compound system of other information sources such
as an electronic chip tray, reduces the vision task to detect cards and chips. Robust results
are achieved by not just analyzing single frames but an image stream regarding game-ß ow
informations. The requirements for such a system are a highly robust and adaptive behav-
ior. This is motivated by the vital interest of casino entrepreneurs in a 100 statistical
analysis of their offered gambling in order to support the business plan, measuring table
and dealer performance and give accurate player rating. Extensive experiments show the
robustness and applicability of the proposed system.
It’s your first day in the lab.Undoubtedly you are experiencing a range
of emotions: excitement, curiosity, anxiety. You will be working in
this lab and with a group of people, as well as with your supervisor,
for several years to come. This is the first day of a long commitment
and, for some, a hard road ahead. Which is why it’s important to get
off on the right foot.
