We consider the possibility that single-source multicast (SSM) will become a universal multicast service, enabling large-scale distribution of content from a few well-known sources to a general audience. Operating under this assumption, we explore the problem of building the traditional IP model of any-source multicast on top of SSM. Toward this end, we design an SSM proxy service that allows a...

Service oriented architecture (SOA) and shared services (SS) have been widely studied in the information technology literature. However, there is a lack of tools for shared services management (SSM) to apply SOA. This paper proposes an ontological map for SSM to apply SOA. This mapping approach, based on the well-known Zachman framework of information architecture, specifies the ontological per...

A new State-Space Model (SSM) based voice conversion method has been proposed recently which outperforms the traditional Gaussian Mixture Model (GMM) method. Although the implementation process of the new method has been elaborated, the theoretical essence of this method has not been analysed clearly. In this paper an exhaustive analysis of the SSM based method is given theoretically and experi...

In southwestern British Columbia, the South Submaritime (ssm) seed planning zone is a geographically and ecologically complex transition zone between the Pacific coast and the interior plateaus. The ssm follows a long, narrow band along the Coast Range (Figure 1), and is characterized by steep, incised valleys. The highly variable climate is strongly influenced by prevailing warm, moist maritim...

Background. We compared Skin-sparing mastectomy (SSM) with immediate breast reconstruction and Non-skin-sparing mastectomy (NSSM), various types of incision in SSM. Method. Records of 202 consecutive breast cancer patients were reviewed retrospectively. Also in the SSM, three types of skin incision were used. Type A was a periareolar incision with a lateral extension, type B was a periareolar i...

BACKGROUND The goal of this study was to determine the length of operative time and its effect on surgeon productivity with the use of intraoperative digital specimen mammography (IDSM) compared to standard specimen mammography (SSM). METHODS A retrospective chart review was performed on 344 consecutive patients from a single breast surgeon from 2003 to 2010. Operative time was compared betwe...

For large-scale multimedia distributions, multicast is the preferred method of communication. ASM (Any Source Multicast) and SSM (SourceSpecific Multicast) are the two types of multicast used. ASM is designed for either many-to-many or one-to-many communication. SSM is derived from ASM. SSM is used when only one session member is allowed to send data. An example use of SSM could be an IPTV broa...

IP multicast is advantageous for high quality streaming applications and future needs in the Internet. However, it is generally recognized that IP multicast requires significant routing coordination and configuration, and hence its routing protocols are non-scalable. Recently, Source-Specific Multicast (SSM) has been standardized and proposed as the deployable IP multicast communication archite...

polar sea ice concentration (SIC) playing important roles in the global climatic and environmental studies. To evaluate the passive microwave SIC we observed sea ice with the 6 m-resolution, Electro-Optical Camera (EOC) sensor onboard KOMPSAT-1 satellite. A total of 72 cloud-free EOC images, 18 km x 18 km each, of arctic sea ice edges were obtained from July to August and 68 images across the a...
