端到端高速网络中的通用QoS解决方案

提出并实现了一种针对端到端高速网络模型的简单有效可行的通用QoS解决方案模型。利用控制数据包容量和服务器端阻塞发送线程的方式限制低级别服务的带宽,从而保证高级别服务拥有更高带宽。根据概率原理设计了四种支持QoS的竞争调度算法,并进一步探索了用于提高带宽利用率的局部搜索和全局优化的手段。基于此方案实现了一个有效的、可扩展的QoS控制核心,并设计实现了一个应用实例。

Evaluating robustness in a two layer simulated robot architecture

Many two layer robot architectures have been proposed and implemented. While justification for the design can be well argued, how does one know it is really a good idea? In this paper, one describes a two layer architecture (reinforcement learning in the bottom layer and POMDP planning at the top) for a simulated robot and summarize a set of three experiments in which one evaluated the design. To address the many difficulties of evaluating robot architectures, one advocates an experimental approach in which design criteria are elucidated and then form the basis for the evaluation experiments. In our case, one tests the implementation for its reliability and generalization (our design criteria) by comparing our architecture to one in which a key component is substituted; in these experiments, one demonstrates significant performance gains on the design criteria for our architecture.

Computational investigation of the antagonism effect towards GluN2B-Containing NMDA receptor: Combined ligand-based and target-based approach

The interaction of GluN2B-Containing NMDA Receptor with 18 antagonists were investigated by a combined ligand-based and target-based approach. First, two distinct pharmacophore models were generated for antagonists which cluster in two groups with Catalyst (HipHop module). The pharmacophore of “ifenprodil group” antagonists includes three hydrophobic groups, one H-bond donor and one H-bond acceptor, the pharmacophore of “EVT101 group” antagonists involves one aromatic ring, two hydrophobic groups and one H-bond acceptor. Docking results and pharmacophore model confrontation allow the pharmacodynamic characteristics to be weighted and structural information integrated. Which results in the proposal of two interaction models inside the GluN2B binding cavity for two groups of antagonists. The interaction model of “ifenprodil group” antagonists consists of one hydrophobic group, one H-bond donor, one H-bond acceptor and an aromatic ring, while on the other hand, the interaction model of “EVT101 group” antagonists includes three hydrophobic groups and an aromatic ring.

An algorithm for hierarchical reduction and decomposition of a directed graph

With the algorithm described, it is possible to decompose a directed graph without loops and cycles into subgraphs which have one and only one source, one and only one sink and no other connections to the complement of the subgraph. The algorithm delivers all subgraphs with this property and the hierarchical structure of these subgraphs. Examples and some experiences on computing time are given.     

Emulator Architecture

Upgrading to a newer data processing system is not simply a matter of removing the old equipment and plugging in the new. The older system's workload must be transferred to the newer one/p=n-/and the newer one is usually also a fundamentally different one. The effort involved in such a conversion is massive. The difficulties of obtaining a smooth transition from one machine to the next are immense.
