GPS系統接收數據坐標轉換 GPS接收的數據往往是三維坐標，而在科學研究中我們通常用二維坐標。因此必須 進行坐標轉換，下面我們介紹一種坐標轉換，即把WGS84坐標轉換為高斯—克呂 格坐標系。數字地圖投影的方法很多，而我國采用了高斯—克呂格投影，它是一 種橫軸橢園柱面等角投影，用一個橢球柱面與地球橢球在某一子午圈L0上相切， 這條子午線通常稱做投影軸子午線。也就是高斯-克呂格投影直角坐標系的x 軸， 地球的赤道與橢圓柱面相交, 成一直線,這條直線與軸子午線正交,就是平面直角坐 標系的y軸，把橢球柱面展開，就得到以（x,y）為坐標的平面直角坐標系。為減少 投影變形，按經度把橢球分為許多帶，各帶分別投影，經常采用的是3度和6度帶。 為使y值不為負值，通常在y軸上加上500km。 已知WGS84坐標（B，L），B為GPS定位輸出成果的緯度，L為GPS定位輸出成果的經度。 由WGS84到高斯-克呂格坐標(x,y)的轉換成高斯投影正算，詳見本軟件

創建兩個生產者進程和兩個消費者進程，生產者進程a需要生成10000個整數,每次都將自己的進程號（用getpid()函數獲得）和生成的整數放入共享內存中（共享內存大小為64Byte）。生產者b每次從26個英文字母中選一個，并將自己的進程號和選中的字母放入共享內存中，直到26個字母全部都選中。消費者進程c負責從共享內存中讀取數據生產者進程a的數據并且將這些數據寫入文件a.out。消費者進程d從共享內存讀取進程b的數據后寫入b.out中。

This article describes how to consume Web services in Java 1.5.0 using the new JAX-WS 2.0 API (JSR 228). Developers around the world, including me, have always complained about the hard ways to work in Java to consume even a Web service as simple as adding two numbers. However, with JAX-WS 2.0 API now available in core Java in JDK 1.5.0, life is simple like never before.

In computer vision, sets of data acquired by sampling the same scene or object at different times, or from different perspectives, will be in different coordinate systems. Image registration is the process of transforming the different sets of data into one coordinate system. Registration is necessary in order to be able to compare or integrate the data obtained from different measurements. Image registration is the process of transforming the different sets of data into one coordinate system. To be precise it involves finding transformations that relate spatial information conveyed in one image to that in another or in physical space. Image registration is performed on a series of at least two images, where one of these images is the reference image to which all the others will be registered. The other images are referred to as target images.
