IENCE C • •S T S E C Small world for dynamic wireless cyber-physical N O H I N systems S O I V Dissertation L • O S 142 G T Y H • R Industries and consumer markets are today increasingly using G I E L VTT SCIEN CE S H E G services exposed from wireless sensor and actuator networks, A I R H C cyber-physical machine-to-machine systems. The motivation for H the research arises from problems detected in the remote 1 4 2 interaction with embedded devices over dynamic wireless networks in such systems. The selected approach is based on the application of the small- world paradigm to cyber-physical systems. It is here assumed that the concept of small world, "six degrees of separation", can be expanded to also cover communication with wireless embedded devices in cyber-physical systems context. The main contributions are the technical enablers referred to as dynamic communication spaces, dynamic M2M service spaces, configuration and remote use of services, communication overlay, access systems selection, integrated mobility, secure ad hoc networking, situated opportunistic communication, hierarchical networking for small-world networks, and short-cuts for network optimization. The enablers have been evaluated as separate technical methods and means by means of experiments and/or simulations. According to the evaluations, the enablers seem to work well as separate building blocks and that they can be combined to expand the concept of small world to also cover communication with embedded devices. Wireless short-cuts can improve the scalability and efficiency of dynamic wireless networking and weak links are essential in the neighbour discovery process. -
Ubuntu Kung Fu
Prepared exclusively for Alison Tyler Download at Boykma.Com What readers are saying about Ubuntu Kung Fu Ubuntu Kung Fu is excellent. The tips are fun and the hope of discov- ering hidden gems makes it a worthwhile task. John Southern Former editor of Linux Magazine I enjoyed Ubuntu Kung Fu and learned some new things. I would rec- ommend this book—nice tips and a lot of fun to be had. Carthik Sharma Creator of the Ubuntu Blog (http://ubuntu.wordpress.com) Wow! There are some great tips here! I have used Ubuntu since April 2005, starting with version 5.04. I found much in this book to inspire me and to teach me, and it answered lingering questions I didn’t know I had. The book is a good resource that I will gladly recommend to both newcomers and veteran users. Matthew Helmke Administrator, Ubuntu Forums Ubuntu Kung Fu is a fantastic compendium of useful, uncommon Ubuntu knowledge.

The main commercial support (and development funding) is available from Canonical, Ltd. They supply reasonably- priced support contracts on a per desktop or per-server basis. For more information see the Ubuntu Advantage page. Community support is also provided by dedicated individuals and companies that wish to make Ubuntu the best distribution possible. Support is provided through multiple mailing lists, IRC channels, forums, blogs, wikis, etc. The large amount of information available can be overwhelming, but a good search engine query can usually provide an answer to your questions. -

It is an unique identifier, and that is how we can reference a specific process; • PPID | The parent's PID. Every (almost) process has a parent process, the process that was responsible for its creation; • TTY | This is a identifier of the terminal session that triggered this process. -
