By introducing video-quality adaptation mechanisms into intermediate network equipments using active network technologies, we can provide users with video distribution services taking into account client-to-client heterogeneity in terms of available bandwidth, performance of client systems, and user’s preferences about video quality. In this paper, we designed and implemented an active video-qu...

The active distribution network (ADN) shows great potential for use in restoration services, given its ability to actively control the topology, distributed generation (DG) outputs, and demand response (DR) resources. However, utility may be limited due geographical dispersion of DG DR resources when applied natural disasters such as windstorms, earthquakes, floods. In addition, increasing rene...

nowadays, efficient goods distribution in target markets is one of the most important challenges of marketing managers and goods producers. distribution of goods and services has a significant contribution in gross domestic product (gdp) of countries. so an efficient distribution network can support constant economic development of countries and reduces end-user price of products. identifying a...

The active distribution network (ADN) can provide the reactive power ancillary service (RPAS) to improve operations of transmission (such as voltage control and loss reduction) generation grows. In this context, an RPAS market is required motivate ADN since system operator (TSO) (DSO) are different entities. Hence, obtain TSO–DSO coordination in market, study proposes a two-stage framework on b...

regarding the nature of non-linear discrete placement, and in order to determine the optimal capacity of the substation, the goal in the present study will be a number of local optimum points. in this research, the problem of optimal placement posts to reduce power losses by considering distributed generation (dg). in formulating the objective function, geographical distribution density in the ...

This paper proposes two frameworks for secure multicast on active networks. The frameworks exploit the computational power of active networks to provide the security desired for multicast, while removing drawbacks in traditional approaches. The main security component in the frameworks is the Active Capability(AC) which replaces the passive session key. The main advantages of using an AC are la...

This paper presents new methods to automatically build Point Distribution Models for faces represented in images. These models consider significant points of faces from several images and study them in order to obtain the mean shape of the object and the main modes of variation. Active Shape Models and Active Appearance Models use the Point Distribution Model to segment the modelled object in n...
