The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

Distribution generator Here is a simple generator which can build some distributions with given properties. Distributions generator (compile with -lm) Typical use might be: ./distributions -u -m 1 -M 10 -n 100 -s 500 Generates a distribution of 100 uniform random numbers between 1 and 10, such that the sum of numbers is 500. ./distributions -p -2.2 -m 1 -M 100 -n 200 -s 500 Idem with 200 numbers between 1 and 100 following a power law with exponent -

SQL Server 2005 Service Broker (SSB) is an asynchronous messaging technology built into SQL Server. With SSB, you essentially get the power of messaging technologies like Microsoft Message Queue (MSMQ) combined with the relational database capabilities of SQL Server, all controlled with Transact SQL statements

how to extend an OLE DB consumer template class and make it much easier to use in applications. I had also explained how you can utilize the power of C++ exception-handling feature to make your work easier, especially in error handling. It was just a small class in my last article.

Learning Kernel Classifiers: Theory and Algorithms, Introduction This chapter introduces the general problem of machine learning and how it relates to statistical inference. 1.1 The Learning Problem and (Statistical) Inference It was only a few years after the introduction of the first computer that one of man’s greatest dreams seemed to be realizable—artificial intelligence. Bearing in mind that in the early days the most powerful computers had much less computational power than a cell phone today, it comes as no surprise that much theoretical research on the potential of machines’ capabilities to learn took place at this time. This becomes a computational problem as soon as the dataset gets larger than a few hundred examples.

FLASH文件系统的源码,Flash memory is a nonvolatile memory, which allows the user to electrically program (write) and erase information. The exponential growth of flash memory has made this technology an indispensable part of hundreds of millions of electronic devices. Flash memory has several significant differences with volatile (RAM) memory and hard drive technologies which requires unique software drivers and file systems. This paper provides an overview of file systems for flash memory and focuses on the unique software requirements of flash memory devices.
