Classic VHF sound broadcasting The VHF FM transmitters can be used as stand-alones, in passive (1+1) or (n+1) at its very best standby configurations and with exciter standby. All modules and units are accommodated in a 19-inch rack for Despite digital audio and video broadcasting, forecasts still anticipate an attrac- ease of access.

DB/C Newsletter February 2006
DB/C Newsletter February 2006 News and Comment This month's article is a very preliminary report about Windows Vista, the next release of Microsoft Windows. I encourage any readers of this newsletter who have had experience with Windows Vista to share it with other DB/C software users via the dbctalk email list. I will be attending the EclipseCon (www.eclipsecon.org) conference in Santa Clara, California March 21-23. Be sure to make contact with me if you are also attending. I'll be reporting about the conference in next month's newsletter. [email protected] A Preliminary Overview of Windows Vista Microsoft recently announced that Windows Vista will be released in five or six different versions, depending on which press release you read. The five versions named on the Microsoft web site are Windows Vista Home Basic Windows Vista Home Premium Windows Vista Ultimate Windows Vista Business Windows Vista Enterprise One interesting thing to note is that the way versions were organized for Windows XP is going away. There will no longer be versions specifically for 64 bit processors, for the Tablet PC or for home multimedia. Windows Vista Ultimate will contain all of the home and business features of the other versions of Windows Vista. No official release dates have been announced for the different versions of Windows Vista, but it seems to be general knowledge that the home versions will be released before the end of 2006 and the business versions will follow in the first half of 2007. No pricing has been announced. -

1 Semantic File Retrieval in File Systems using Virtual Directories Prashanth Mohan, Raghuraman, Venkateswaran S and Dr. Arul Siromoney {prashmohan, raaghum2222, wenkat.s}@gmail.com and [email protected] Abstract— Hard Disk capacity is no longer a problem. How- ‘/home/user/docs/univ/project’ directory lists the ever, increasing disk capacity has brought with it a new problem, file. The ‘Database File System’ [2], encounters this prob- the problem of locating files. Retrieving a document from a lem by listing recursively all the files within each directory. myriad of files and directories is no easy task. Industry solutions are being created to address this short coming. Thereby a funneling of the files is done by moving through We propose to create an extendable UNIX based File System sub-directories. which will integrate searching as a basic function of the file The objective of our project (henceforth reffered to as system. The File System will provide Virtual Directories which SemFS) is to give the user the choice between a traditional list the results of a query. The contents of the Virtual Directory heirarchial mode of access and a query based mechanism is formed at runtime. Although, the Virtual Directory is used mainly to facilitate the searching of file, It can also be used by which will be presented using virtual directories [1], [5]. These plugins to interpret other queries. virtual directories do not exist on the disk as separate files but will be created in memory at runtime, as per the directory Index Terms— Semantic File System, Virtual Directory, Meta Data name. -
