Especially, its operation does not depend on packet dropping. In chapter 5, we have analyzed the relation between link rate and link price of the Newton-like algorithm, which is proposed by Low et al to solve the utility function. And then we reduce the convergence procedure of Newton-like algorithm to a simple recursive procedure along a convex curve after the reduction and mathematical derivation. Thus, we found the reason that leads to the severe fluctuation of the sending rate during its convergence procedure, and then proposed our improved algorithm.

在第五章，我们在对Low等人提出的用于解决效益函数的Newton-like算法的链路速率与链路价格之间关系的深入分析的基础上，经过简化和数学推导，我们将其收敛过程归结为沿着一个凸曲线的非常简单的收敛过程，由此找到了导致Newton-like算法收敛过程中信源速率振荡剧烈的原因，在此基础上，我们提出了一个改进的链路算法。

The main contribution of this thesis is that we propose a collaborative filtering recommendation algorithm based on double clustering. This approach first respectively clusters resources and users by the users rating on items, then makes a collaborative filtering recommendation based on the clustering result. The new algorithm can shorten on-line recommendation time. Then, we apply the classical formula of cosine correlation to double clustering algorithm, leaving out the standardization operation. In the end, we implement an educational resource recommender system according to the need of the actual project and the result is positive.

本文的主要意义在于，首先运用聚类技术对用户和资源分别进行聚类，然后利用聚类结果进行协同过滤推荐，由于聚类部分离线周期进行，大大缩短了在线的推荐时间；然后将经典的余弦相似性计算公式运用到双重聚类算法中，省去规范化处理操作，减少运算量；最后结合实际的需要，实现一个资源推荐系统。

Its five visceras and six mansions is the entity"equipments" that carries on bio-chemical reaction continuously, but skeleton,muscle,skin etc. the organization then props up,protect these entity of equipments , and with the external world contiguous necessary outer circle hardware;The meridian is the living creature information system that colludes with to live the quick and the external world contact and combines to adjust bio-chemical reaction of oneself continuously;The acupoint then the information commutation crunode of the spirit lifeblood, the spirit blood this physiology media wears through the acupoint movement deeply to make in the viscera in the veins and arteries,function they adjust the speed,for enzyme that the bio-chemical responds process to provide continuously etc., live the human body normal physiology metabolism by assurance, maintain life to continue, evolution with multiply greatly.

其五脏六腑是不断进行生化反应的实体"设备"，而骨骼、肌肉、皮肤等组织则是支撑、保护这些实体设备，并与外界接触的必要外围硬件；经络是勾通活人体与外界联系、并不断调整自身生化反应的生物信息系统；腧穴则是经络的信息交换结点，气血这个生理传媒通过腧穴运行穿透于经络、作用于五脏六腑使它们不断调整生化反应过程的速度、酶供等，以保证活人体正常生理代谢，维持生命延续，进化和繁衍。

University of Central Florida biomedical scientists led by Professor Henry Daniell found insulin might someday be grown in genetically modified plants and then be used to prevent diabetes before symptoms appear or to treat the disease in its later stagesDaniell's research team genetically engineered tobacco plants with the insulin gene and then administered freeze-dried plant cells to five-week-old diabetic mice as a powder for eight weeks.

在弗罗里达中央大学，由Henry Daniell教授带领的生物医学学家们发现胰岛素可以在转基因植物中生产，以用来在症状出现之前预防糖尿病或在疾病晚期治疗糖尿病。Daniel的研究小组将胰岛素基因通过基因工程技术重组到烟草植物之中，再将经过冷冻干燥过的植物细胞用作粉剂喂食五周大的糖尿病鼠8周。

When you feel deeply hurt, and tears are about to drop down , then please take a glance at the sky that used to belong to you. When the sky is still expansive, clouds are still degage, then there is no reason to cry , for the world that you alway have is not taken away by anyone's leave.

当你的心真的在痛，眼泪快要流下来的时候，那就赶快抬头看看，这片曾经属于你的天空；当天依旧是那么的广阔，云依旧那么的潇洒，那就不应该哭，因为他人的离去，并没有带走你的世界。

Firstly, the reduced dynamic model including motor dynamics is developed for mobile manipulators. The system is then decomposed into four lower-dimensional subsystems by applying diffeomorphism and nonlinear input transformation to the reduced model. The design of the second order dynamical sliding mode controller is then addressed for the output tracking of mobile manipulators.
