Component technology is only available for business-oriented quality of service (QoS) management functions, can not satisfy the QoS requirements of soft real-time applications areas such as the multimedia and Web services. For real-time guarantee and improving resource utilization needs, this paper presents a real-time scheduling model for soft real-time component-oriented systems. First, the task...
An improved model for portfolio selection based on particle swarm optimization with escape velocity (EVPSO) algorithm is proposed. Firstly, the predilection coefficient is introduced to the model to make the investor choose the invest project according to their preference and find the balance between the invest income and risk conveniently. Secondly, the EVPSO algorithm is applied to the model to...
Epithelial-stromal interactions play a crucial role in normal embryonic development and carcinogenesis of the human breast while the underlying mechanisms of these events remain poorly understood. Here, we constructed a physiologically relevant, 3D culture surrogate of complex human breast tissue that included a tri-culture system made up of human mammary epithelial cells (MCF10A), fibroblasts and...
The existing active queue management (AQM) algorithms are not well adapted to the uncertainty of the time-delay networks. When an algorithm designed for the small time-delay network (LAN) is used for a large-delay networks (WAN, Internet), its performance is normally poor. This paper presents a robust AQM design algorithm based on the D stability region to overcome this issue. The TCP/AQM model meeting...
