Mobile Telemedicine and Wireless Remote Monitoring Applications
İSTANBUL TECHNICAL UNIVERSITY INSTITUTE OF SCIENCE AND TECHNOLOGY MOBILE TELEMEDICINE AND WIRELESS REMOTE MONITORING APPLICATIONS M.Sc. Thesis by Taner SOYUGENÇ, B.Sc. Department : Electronics and Communication Engineering Programme : Biomedical Engineering NOVEMBER 2006 PREFACE In this project, my main goal is to implement a mobile sample application by defining the related global standards for telemedicine. The work is focused on recommendations of technology associated with a feasibility study. First of all, I would like to thank Assoc. Prof. Dr. Selçuk PAKER for his valuable advice, support and encouragement to accomplish the project. Besides, I would like to thank my family who is always with me giving support at every step of my life.

Mainly targeted at the web and its standards, it has been successfully used in a lot of different contexts. Thanks to its pluggable architecture it can be extended without limits to support more platforms and languages. Cur- rently, you can write plugins in C, C++ and Objective-C. The “WSGI” part in the name is a tribute to the namesake Python standard, as it has been the first developed plugin for the project. Versatility, performance, low-resource usage and reliability are the strengths of the project (and the only rules fol- lowed). Contents 1 uWSGI Documentation, Release 1.9 2 Contents CHAPTER 1 Included components (updated to latest stable release) The Core (implements configuration, processes management, sockets creation, monitoring, logging, shared memory areas, ipc, cluster membership and the uWSGI Subscription Server) Request plugins (implement application server interfaces for various languages and platforms: WSGI, PSGI, Rack, Lua WSAPI, CGI, PHP, Go ...) Gateways (implement load balancers, proxies and routers) The Emperor (implements massive instances management and monitoring) Loop engines (implement concurrency, components can be run in preforking, threaded, asynchronous/evented and green thread/coroutine modes. -

Well, yes and no. The Ruby Performance Dichotomy Framework Code VS Application Code Benchmarking: The only way to really know performance characteristics Profiling: Measure don’t guess. ruby-prof What is all this good for in real life? Merb Merb Like most useful code it started as a hack, Merb == Mongrel + Erb • No cgi.rb !! • Clean room implementation of ActionPack • Thread Safe with configurable Mutex Locks • Rails compatible REST routing • No Magic( well less anyway ;) • Did I mention no cgi.rb? • Fast! On average 2-4 times faster than rails Design Goals • Small core framework for the VC in MVC • ORM agnostic, use ActiveRecord, Sequel, DataMapper or roll your own db access. • Prefer simple code over magic code • Keep the stack traces short( I’m looking at you alias_method_chain) • Thread safe, reentrant code Merb Hello World No code is faster then no code • Simplicity and clarity trumps magic every time. • When in doubt leave it out. • Core framework to stay small and simple and easy to extend without gross hacks • Prefer plugins for non core functionality • Plugins can be gems Key Differences • No auto-render. The return value of your controller actions is what gets returned to client • Merb’s render method just returns a string, allowing for multiple renders and more flexibility • PartController’s allow for encapsualted applets without big performance cost Why not work on Rails instead of making a new framework? • Originally I was trying to optimize Rails and make it more thread safe. -

Load Balancing for Heterogeneous Web Servers
Load Balancing for Heterogeneous Web Servers Adam Pi´orkowski1, Aleksander Kempny2, Adrian Hajduk1, and Jacek Strzelczyk1 1 Department of Geoinfomatics and Applied Computer Science, AGH University of Science and Technology, Cracow, Poland {adam.piorkowski,jacek.strzelczyk}@agh.edu.pl http://www.agh.edu.pl 2 Adult Congenital and Valvular Heart Disease Center University of Muenster, Muenster, Germany [email protected] http://www.ukmuenster.de Abstract. A load balancing issue for heterogeneous web servers is de- scribed in this article. The review of algorithms and solutions is shown. The selected Internet service for on-line echocardiography training is presented. The independence of simultaneous requests for this server is proved. Results of experimental tests are presented3. Key words: load balancing, scalability, web server, minimum response time, throughput, on-line simulator 1 Introduction Modern web servers can handle millions of queries, although the performance of a single node is limited. Performance can be continuously increased, if the services are designed so that they can be scaled. The concept of scalability is closely related to load balancing. This technique has been used since the beginning of the first distributed systems, including rich client architecture. Most of the complex web systems use load balancing to improve performance, availability and security [1{4]. 2 Load Balancing in Cluster of web servers Clustering of web servers is a method of constructing scalable Internet services. The basic idea behind the construction of such a service is to set the relay server 3 This is the accepted version of: Piorkowski, A., Kempny, A., Hajduk, A., Strzelczyk, J.: Load Balancing for Heterogeneous Web Servers. -
