The second volume in the Write Great Code series supplies the critical information that today s computer science students don t often get from college and university courses: How to carefully choose their high-level language statements to produce efficient code. Write Great Code, Volume 2: Thinking Low-Level, Writing High-Level, teaches software engineers how compilers translate high-level language statements and data structures into machine code. Armed with this knowledge, a software engineer can make an informed choice concerning the use of those high-level structures to help the compiler produce far better machine code--all without having to give up the productivity and portability benefits of using a high-level language

This manual describes Freescale’s IEEE™ 802.15.4 Standard compliant MAC/PHY software. The Freescale 802.15.4 MAC/PHY software is designed for use with the Freescale MC1319x and MC1320x, family of short range, low power, 2.4 GHz Industrial, Scientific, and Medical (ISM) band transceivers, designed for use with the HCS08 Family of MCUs. The MAC/PHY software also works with the MC1321x family of short range, low power, 2.4 GHz ISM band transceivers that incorporate a low power 2.4 GHz radio frequency transceiver and an 8-bit microcontroller into a single LGA package. Throughout this manual, the term transceiver refers to either the MC1319x, MC1320x, or the internal counterpart inside the MC1321x System in a Package (SiP).

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

1、提取原蛋白質相互作用網絡的所有節點 2、分別計算原蛋白質相互作用網絡每個節點的度 3、從所有節點中選擇具有最高度的節點，反復的添加邊，直到它的度值等于原蛋白質相互作用網絡該節點的度值 4、在為節點添加邊時，從剩余節點中選擇節點的方法是其度分布近似服從power-low分布 5、令t的值為零，則每個節點被選到的可能性都是相同的，由于在原蛋白質相互作用網絡存在大量的低度節點，所以集散節點會優先連接低度節點。 這樣創建的網絡就為負相關蛋白質互作網絡

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute. Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets a systematic way of dealing with datasets having components of non-uniform length tools for fine-tuning figures using compact, straightforward statements and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.

用fpga實現的DA轉換器，有說明和源碼，VDHL文件。 A PLD Based Delta-Sigma DAC Delta-Sigma modulation is the simple, yet powerful, technique responsible for the extraordinary performance and low cost of today s audio CD players. The simplest Delta-Sigma DAC consists of a Delta-Sigma modulator and a one bit DAC. Since, both of these components can be realized using digital circuits, it is possible to implement a low precision Delta-Sigma DAC using a PLD.

The main features of the considered identification problem are that there is no an a priori separation of the variables into inputs and outputs and the approximation criterion, called misfit, does not depend on the model representation. The misfit is defined as the minimum of the l2-norm between the given time series and a time series that is consistent with the approximate model. The misfit is equal to zero if and only if the model is exact and the smaller the misfit is (by definition) the more accurate the model is. The considered model class consists of all linear time-invariant systems of bounded complexity and the complexity is specified by the number of inputs and the smallest number of lags in a difference equation representation. We present a Matlab function for approximate identification based on misfit minimization. Although the problem formulation is representation independent, we use input/state/output representations of the system in order
