Description: 落煤残存瓦斯量的确定是采掘工作面瓦斯涌出量预测的重要环节,它直接影响着采掘工作面瓦斯涌出量预测的精度,并与煤的变质程度、落煤粒度、原始瓦斯含量、暴露时间等影响因素呈非线性关系。人工神经网络具有表示任意非线性关系和学习的能力,是解决复杂非线性、不确定性和时变性问题的新思想和新方法。基于此,作者提出自适应神经网络的落煤残存瓦斯量预测模型,并结合不同矿井落煤残存瓦斯量的实际测定结果进行验证研究。结果表明,自适应调整权值的变步长BP神经网络模型预测精度高,收敛速度快 该预测模型的应用可为采掘工作面瓦斯涌出量的动态预测提供可靠的基础数据,为采掘工作面落煤残存瓦斯量的确定提出了一种全新的方法和思路。-charged residual coal gas is to determine the volume of mining gas emission rate forecast an important link, which directly affect mining gas emission rate forecast accuracy, and with coal metamorphism, loading coal particle size, the original gas content, exposure time and other factors nonlinear relationship. Artificial neural networks have expressed arbitrary nonlinear relationships and the ability to solve complex nonlinear, time-varying uncertainty and the new ideas and new approaches. Based on this, the author of adaptive neural network loading coal residual gas production forecast model, and a combination of different loading coal mine gas remnants of the actual test results of research. Results show that the adaptive value of the right to change step BP neural network model predict

Description: 这是完整的一个C/S的客户服务端程序！但是我希望加点功能！请大家帮帮忙，“我要做的是客户端和服务器正常运行的情况下，如果网络断了，（比如说我把网络弄掉了，然后再接好）过了一会网络恢复正常，客户端能自动连接到服务器端，不能人工干涉！ 我查了一些资料，在VC里有一个函数OnTimer(nIDEvent)可以定时产生事件！可以实现这个功能，但是我用了，还是连不上，请大家帮帮忙吧！做好后给我发到我的邮箱里！谢谢！-This is a complete C/S programe,but I hope put more function into it.Please help me.Fllowing is I ll want to do.When client is communicating with server normally,the network link is down. After while the link recovery(ie,I take the cable out from the computer then plug it in.)The Client can reconnect the server automatically not redo by human.I study some reference information to do it.There is a function OnTimer(nIDEvent) in VC can send event message periodically.But I still can t reconnect.Please help me to do it and then mail to me. Thanks.

Description: 求图的顶点连通度算法。方法就是先对源和汇做枚举，之后对每个枚举情况，把除去源汇两点的其余所有顶点看成是容量限制为1的点，求网络的最大流，就是此点对的顶点连通度，之后对枚举的所有点对找连通度最小的当成图的连通度。
带有顶点容量限制的最大流方法：将带容量限制的顶点u拆成两个点u 和u*，原顶点u的入边为u 的入边，原顶点u的出边为u*的出边，之后在u 和u*之间连接双向边，边的容量为顶点的容量限制。-plans for the vertex connectivity algorithms. First is the method of sources and sinks so enumerated, after the enumeration of each, two sources and sinks to remove all remaining vertices as capacity constraints to a point, seeking the largest network flow, this is the apex of connectivity, followed by enumeration of all points of connectivity for the smallest of the plan as connectivity. Vertex capacity constraints with the biggest flow method : with the capacity constraints of the vertex is split into two u u and u*, the original entry point u u edge of the income side, the original point out u* u edge of the edge out after the u and u* a two-way link between the edge, while the capacity for the top point of the capacity constraints.

Description: 随着无线mesh网络的普及，其规模和复杂程度持续发展。然而多跳的mesh网络遇到越来越多的难题，比如带宽降低，无线干扰以及网络时延等。譬如，在网络中的每一跳吞吐量会下降多达50％，连续多跳情况下吞吐量下降得更迅速，其结果将导致网络性能的严重降低。在语音和视频应用大量运行的极端情况下，时延和RF干扰将达到不可接受的程度，而导致连接完全中断-wireless mesh network with the popularity of its size and complexity of sustainable development. However, multi-hop mesh networks encountered more and more problems, such as lower bandwidth, wireless interference and network delay, and so on. For example, in each of the network throughput would drop jump up to 50%, for a number of cases jumped more rapid decline in throughput, The results will lead to serious network performance lower. In voice and video applications running of a large number of extreme cases, delay and RF interference will reach an unacceptable level. which led to the link severed

Description: 本文主要研究了W-WAN中GPRS网络的移动视频传输问题。文中探讨了GPRS的网络结构、协议体系以及链路特性，从中我们看出：
GPRS网络链路不仅具有一般无线链路数据传输中遇到的延迟大、误码率高等共性问题，而且具有移动通信系统采用蜂窝频率复用方式带来的小区切换，
以及由于通信中链路性能随着地理位置变换而变化造成的GPRS网络中不可避免的经常性遭遇的冗长时延和突变时延。
这使得目前GPRS网络中使用的传统TCP或UDP传输协议均不能适应GPRS自身的链路特性，也不能实现高效的分组传输。-This paper mainly studied the W-WAN in the GPRS network for mobile video transmission problems. The article discusses the GPRS network architecture, protocol architecture, as well as link characteristics, from which we can see: GPRS network link not only has the general wireless link data transmission delay encountered in large, common problems of higher bit error rate, and with mobile communications system uses a cellular frequency reuse methods brought about by cell switching, as well as the communication link performance with the location change and change is inevitable GPRS network, the recurrent encountered lengthy delay and delay mutation. This makes the current GPRS network using the traditional TCP or UDP transport protocol are unable to adapt its own GPRS link characteristics, but also efficient packet transmission can not be achieved.
