The production of carotenoids, lipid content, and fatty acid composition were all studied in a strain of Sporobolomyces ruberrimus when using different concentrations of technical glycerol as the carbon source and ammonium sulfate as the nitrogen source. The total lipids represented an average of 13% of the dry weight, and the maximum lipids were obtained(More)
An experiment was conducted to investigate the effect of short-term selection for 4 week breast weight (4wk BRW), and to estimate genetic parameters of body weight, and carcass traits. A selection (S) line and control (C) line was randomly selected from a base population. Data were collected over two consecutive hatches for four generations. A total of 1(More)
A technical prerequisite for a converged network is a common service delivery platform that is independent from the access networks below. The 3GPP SIP-based IP Multimedia Subsystem (IMS) is defined for this purpose. By specification, IMS is the first implementation towards reaching converged communications which allows users to communicate with video,(More)
A technical prerequisite for a converged network is a common service delivery platform that is independent from the access networks. The 3GPP SIP-based IP Multimedia Subsystem is defined for this purpose. On the other hand, Internet Protocol-based television (IPTV) is defined as multimedia services such as television/ video/ audio/ text/ graphics/ data(More)
NGN equipment manufacturers present their own solutions in order to implement NGN architecture in telecom networks. The IMS-TISPAN model is reference for these solutions. This model only defines NGN functionalities, so there are various solutions to map these functions to physical nodes. In this paper we compared Siemens, Ericsson, ZTE and Huawei solutions(More)
In this paper, we consider the problem of pricing for optimal resource allocation service using Engineering Optimization with Particle Swarm algorithm that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. We formulate our generalized optimization algorithm based on the notion(More)
Next Generation Network (NGN), is the new approach for the operators to offer a more wide range of applications and services. Meanwhile, different Next Generation Network architectures which are proposed by manufacturers cause some ambiguities in forming of this concept in telecommunication networks. Only the required functions are considered for NGN in IP(More)
Coping with complex demands in time-effective manner, supervising a fast growing market and considering performance analysis are all essential steps in opening the national telecommunications market. Therefore, national governments are establishing a formal national Type Approval (TA) system as the basis and frame for accomplishing these goals. In this(More)
IMS was represented in Release 5 (Immigration from 2G to 3G) which had the ability of using SIP protocol. Several test scenarios for different functionalities of SIP user agent have been presented by European Telecommunications Standards Institute (ETSI). In this paper, we present testing scenarios for UPDATE method in SIP user agent. However, no scenarios(More)
