In this paper, we develop bound-preserving discontinuous Galerkin (DG) methods for the coupled system of compressible miscible displacement problems. We consider problem with two components and (volumetric) concentration $i$th component fluid mixture, $c_i$, should be between 0 1. However, $c_i$ does not satisfy maximum principle. Therefore, numerical techniques introduced in [X. Zhang C.-W. Shu, J. Comput. Phys., 229 (2010), pp. 3091--3120] cannot applied directly. The main idea is to apply...
To identify the type of main flow channels complex porous media in oil and gas reservoirs, "main channel index" is defined as ratio comprehensive permeability obtained from well test to matrix core analysis or logging. Meanwhile, a mathematical model established based on equivalent assumption, classification method for put forward, quantitative characterization realized. The has been verified by typical reservoirs. study results show that can quantitatively classify types channels. If index...
Discrete element method was used to study and analyze the interaction between rice straws straw agricultural machinery parts, thereby providing a scientific basis for post-harvest paddy field processing. Calibrations of straw-rice straw, straw-agricultural part contact parameters (collision recovery coefficient, static friction coefficient rolling coefficient) constitute an important prerequisite discrete research process. In this study, collision coefficients straw-steel were 0.230 0.357,...
The development of delay-tolerant networks (DTNs) has attracted significant attention in the network research community. In this paper, we propose a new type DTN - homing-pigeon-based (HoP-DTN). HoP-DTN, each node owns dedicated messenger (called pigeon). only form internode communication is for pigeon to periodically carry batch messages originated at home node, deliver them corresponding destination nodes, and return home. Clearly, given message-expiration times, some may not reach their...
Network coding has been proved as an effective way to enhance the throughput of multihop wireless ad hoc networks in both unicast and multicast traffics. However, a random network topology with non-coding-aware routing protocols, performance enhancement may be limited because packet scheme does not take advantage possibility coding. In this paper, we propose Backbone ROuting Coding (BRONC) over network, which combines benefits backbone techniques. With backbone-based routing, all packets are...
Peer-to-peer (P2P) streaming has become a promising approach for disseminating media content from the server to large number of interested clients. It still faces many challenges, however, such as high churn rate peer clients, uplink bandwidth constraints participating peers, and heterogeneity client capacities. To resolve these issues, this paper presents new P2P framework that combines with advantages both mesh-based multisource overlay networks scalable video coding techniques,...
This paper presents a new collaborative peer-to-peer (P2P) streaming framework for heterogeneous bandwidth capacity of clients. The proposed architecture aims two primary goals: (1) providing higher quality by making best use the extra available that might exist among clients and (2) robustness resilience to high churn rate peers introducing redundancy, both in network paths (multisender overlay) data (multilayered video content). For achieving these goals, we employ gossip-based data-driven...
