volume

I'm using mayavi (3.3.2) to display volume isosurfaces. Generally, my volumes do not have cubic voxels; for example, the sampling grid might be 1mm x 1mm in X and Y, but 1.4mm in the Z direction. How can I get such volumes to display with the correct spatial proportions using mayavi's mlab.contour3d or mlab.pipeline.iso_surface ? I'd really prefer to not resample the volumes to a cubic grid. Another way of stating the problem: what can I do to get the below code to display a sphere instead of a flattened elipsoid (taking the volume with it's intended 1:1:2 aspect-ratio voxels as a given, and

Glusterfs通过TCP/IP或InfiniBand RDMA网络链接将客户端的存储资块源聚集在一起,使用单一的全局命名空间来管理数据,磁盘和内存资源. Glusterfs基于堆叠的用户空间设计,可以为不同的工作负载提供高优的性能. Glusterfs支持运行在任何标准IP网络上标准应用程序的标准客户端，如下图1所示，用户可以在全局统一的命名空间中使用NFS/CIFS等标准协议来访问应用数据. Glusterfs主要特征 扩展性和高性能 高可用 全局统一命名空间 弹性hash算法 弹性卷管理 基于标准协议 工作原理： 1) 首先是在客户端， 用户通过glusterfs的mount point 来读写数据， 对于用户来说，集群系统的存在对用户是完全透明的，用户感觉不到是操作本地系统还是远端的集群系统。 2) 用户的这个操作被递交给 本地linux系统的VFS来处理。 3)

I'm reading a wav-file to a byte array using this method (shown below) . Now that I have it stored inside my byte array, I want to change the sounds volume. private byte[] getAudioFileData(final String filePath) { byte[] data = null; try { final ByteArrayOutputStream baout = new ByteArrayOutputStream(); final File file = new File(filePath); final AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file); byte[] buffer = new byte[4096]; int c; while ((c = audioInputStream.read(buffer, 0, buffer.length)) != -1) { baout.write(buffer, 0, c); } audioInputStream.close(); baout.close(

What frameworks are required to detect how loud someone is talking into a microphone... Also, can anyone tell me what to search for in the documentation or google so I can create some code... What line of code would be commonly used when detecting volume levels of noise through the microphone? Thanks! Erik B This seems to be a duplicate of: Realtime microphone sound level monitoring However, that question is old and the accepted answer links to a deprecated library . They now recommend that you instead use AVAudioRecorder . They suggest this tutorial and it seems to be what you are looking for
