ABSTRACT
We present SOS, the operating system for SOMIW (Secure Open Multimedia Integrated Workstation). The SOS is object-structured; all services and communication is expressed in terms of passive objects with procedural interfaces.Resources are accessed by clients via a local (to the client) proxy object. The possibly distributed or group nature of the resource is hidden behind the proxy interface.The service and its representatives form a single distributed object (or group); any communication protocol is hidden, as part of its internal representation. The proxy is a programmable capability and may be different per-client. This approach also allows the programmer of a resource to cope with the heterogeneous nature of its clients.The OS is based on a kernel which implements contexts, processes, memory segments and object descriptors. Object invocation normally occurs within one context, but may trap transparently into an other context.

SOS: A Distributed Mobile Q&A System Based on Social Networks
ICDCS '12: Proceedings of the 2012 IEEE 32nd International Conference on Distributed Computing SystemsRecently, emerging research efforts have been focused on question and answer (Q\& A) systems based on social networks. The social-based Q\& A systems can answer non-factual questions, which cannot be easily resolved by web search engines. These systems ...

Video Surveillance and SOS Request
ICIAP '07: Proceedings of the 14th International Conference on Image Analysis and ProcessingIn this paper we present an approach to recognize an SOS request through a video surveillance equipment. This project is intended to help the human surveillance operators in outdoor environment. We have fixed a rule to define an SOS request typical in ...
