Description: 十进制N和其它进制数的转换是计算机实现计算的基本问题,其解决方法很多,其中一个简单算法基于下列原理:
N=(N div d)*d+ N mod d ( 其中:div为整除运算,mod为求余运算)
例如十进制向八进制的数制转换 (1348)10=(2504)8，其运算过程如下：
N N div 8 N mod 8
1348 168 4
168 21 0
21 2 5
2 0 2

-there exists a fundamental tradeoff between bandwidth and power. In this thesis, we
propose a novel admission control scheme based on power reservation. Foremost, we
introduce a joint subchannel and power allocation algorithm for WiMAX system, which
minimizes the overall downlink transmit power by utilizing all available subchannels.
Based on this, we propose two power reservation schemes for inter-cell handoff calls and
intra-cell handoff calls, respectively. The amount of reserved power is determined in an
adaptive manner for optimizing the metric of Grade of Service(GoS).

Description: With the amazing progress of computers, the finite element method (FEM) has become
widely used in many practical situations. There exists, however, a large gap between its
industrial applications and academic fundamental studies. One of its reasons is due to the
difficulty in the pre-processing for FEM, i.e. mesh generation. The generation of mesh is
a very difficult task if the degree-of-freedom of the analysis model is extremely large, or
if the geometry of the domain is much complex. In addition, mesh generation is usually
carried out in a sequential algorithm, although parallel computing is becoming available
for large-scale numerical. Therefore, we need to develop a new CAE algorithm, where
parallel computing is employed throughout the process. Especial1y, the sequential
procedure of mesh generation becomes a serious bottleneck in the whole computational
processing, if frequent mesh refinement is required in the problems, Platform: |

Description: One of the most critical issues in the wireless sensor networks is the network s nodes limited availability of energy. The network lifetime strictly depends on its energy efficiency.
Clustering is a method to make the consumed energy efficient. LEACH is one of the fundamental clustering algorithms. In
this paper we have proposed an algorithm which extends LEACH by considering number of neighbors and remaining of the energy of each node to be a cluster head. We have also proposed to use gateway nodes in each cluster to enable the
cluster head to reduce its transmission radius within the cluster to achieve better power saving. We analyze and compared the proposed algorithm along with the LEACH, LEACH-c and MIMO the most recent extend over the LEACH and show that the proposed algorithm can prolong the lifetime of the network.

Description: python的算法书，挺好的，可以下来看看，英文文字版的-Python Algorithms explains the Python approach to algorithm analysis and design. Written by Magnus Lie Hetland, author of Beginning Python, this book is sharply focused on classical algorithms, but it also gives a solid understanding of fundamental algorithmic problem-solving techniques.
The book deals with some of the most important and challenging areas of programming and computer science, but in a highly pedagogic and readable manner.
The book covers both algorithmic theory and programming practice, demonstrating how theory is reflected in real Python programs.
Well-known algorithms and data structures that are built into the Python language are explained, and the user is shown how to implement and evaluate others himself.
What you’ll learn
Transform new problems to well-known algorithmic problems with efficient solutions, or show that the problems belong to classes of problems thought not to be efficiently solvable.

Description: 搞计算机的人都应该很清楚，语言只是一种工具，算法才是灵魂。现在的开发语言有很多，如C++,VB,Perl,java,c#,还有如脚本语言js,vbs等，在如此多的选择面前，很多人不知道该选择哪一种好。其实不管哪一种语言，既然他存在，就一定有他的价值，有它的特定用途，而这往往是其它语言所无法比拟的。譬如C++就适合于系统底层的编程，而java一般就用于对稳定性，兼容性要求较高的场合，正所谓各有所长。像我一般用C++编写网络基层和与操作系统相关的程序，用C#写ASP.NET等程序，必要的时候再辅以Rose, Rational XDE等建模工具。但无论选择哪一种语言，算法才是根本，掌握了算法，就掌握了所有语言的根本，以不变应万变。-Engaged in the computer should be very clear, language is only a tool, the algorithm is the soul.

Description: RANSAC为RANdom SAmple Consensus的缩写，它是根据一组包含异常数据的样本数据集，计算出数据的数学模型参数，得到有效样本数据的算法。它于1981年由Fischler和Bolles最先提出[1]。
RANSAC算法经常用于计算机视觉中。例如，在立体视觉领域中同时解决一对相机的匹配点问题及基本矩阵的计算。
RANSAC算法的基本假设是样本中包含正确数据(inliers，可以被模型描述的数据)，也包含异常数据(Outliers，偏离正常范围很远、无法适应数学模型的数据)，即数据集中含有噪声。这些异常数据可能是由于错误的测量、错误的假设、错误的计算等产生的。同时RANSAC也假设，给定一组正确的数据，存在可以计算出符合这些数据的模型参数的方法。-RANSAC for RANdom SAmple Consensus, it is based on a set of sample data sets contain abnormal data, mathematical model parameters calculated data, the effective sample data algorithm. First proposed by Fischler and Bolles in 1981 [1]. The RANSAC algorithm often used in computer vision. For example, while addressing the three-dimensional visual field on the camera match point problem and the fundamental matrix calculation. The RANSAC algorithm' s basic assumption is that sample contains the correct data (inliers, can be described by the model data) also contain abnormal data (Outliers, deviated from the normal range very far, unable to adapt to the mathematical model of the data), that the data set contains noise. These abnormal data may be generated due to wrong measurements, wrong assumptions, wrong calculation. Simultaneously RANSAC also assume, given a set of correct data, there can be calculated out of these data to the model parameters. Platform: |
