膝关节疼痛在临床上是普遍且发病率高的一种常见症状,其病因复杂多样且难以辨别。膝关节作为人体最大的关节,在行走时起到的支撑作用和做出的屈伸动作对行走这个动作起着重要的作用。长久的行走不可避免会导致腰椎、骨盆、膝关节的各种退行性改变,出现僵硬、疼痛、活动受限及关节的弹响声等症状。膝关节疼痛是膝关节退行性病变的常见症状之一,根据此类疾病症状的特点,中医学将其归类为“膝痹”“历节”“鹤膝风”的范畴。近年来,随着生活方式的改变,其发病率的逐年提高引起了临床工作者的重视。临床中发现有些膝关节疼痛患者X线检查时显示未见明显异常,但其往往伴随着腰痛等腰部不适的症状,有些患者腰椎X线或CT检查时会出现腰椎侧弯、腰椎间盘突出等症状,在给其做体格检查时腰部会有明显的压痛点,通过膝关节的局部推拿及通督正脊术从腰论治整复脊柱后,患者膝关节疼痛的症状会有明显的改善。

K-Nearest Neighbor Based Missing Data Estimation Algorithm in Wireless Sensor Networks

引用

Wireless Sensor Network 2010年第2期2卷 115-122页

作者： liqiang Pan jianzhong li 不详

In wireless sensor networks, the missing of sensor data is inevitable due to the inherent characteristic of wireless sensor networks, and it causes many difficulties in various applications. To solve the problem, the missing data should be estimated as accurately as possible. In this paper, a k-nearest neighbor based missing data estimation algorithm is proposed based on the temporal and spatial correlation of sensor data. It adopts the linear regression model to describe the spatial correlation of sensor data among different sensor nodes, and utilizes the data information of multiple neighbor nodes to estimate the missing data jointly rather than independently, so that a stable and reliable estimation performance can be achieved. Experimental results on two real-world datasets show that the proposed algorithm can estimate the missing data accurately.

Efficient Pr-Skyline Query Processing and Optimization in Wireless Sensor Networks

引用

Wireless Sensor Network 2010年第11期2卷 838-849页

作者： jianzhong li Shuguang Xiong 不详

As one of the commonly used queries in modern databases, skyline query has received extensive attention from database research community. The uncertainty of the data in wireless sensor networks makes the corresponding skyline uncertain and not unique. This paper investigates the Pr-Skyline problem, i.e., how to compute the skyline with the highest existence probability in a computational and energy-efficient way. We formulate the problem and prove that it is NP-Complete and cannot be approximated in a given expression. However, the proposed algorithm SKY-SEARCH with pruning techniques can guarantee the computational efficiency given relatively large input size, while the filter-based distributed optimization strategy significantly reduces the transmission cost and the required storage space of the sensor nodes. Extensive experiments verify the efficiency and scalability of SKY-SEARCH and the distributed optimizing strategy.

Compressing Information of Target Tracking in Wireless Sensor Networks

引用

Wireless Sensor Network 2011年第2期3卷 73-81页

作者： jianzhong li Qianqian Ren 不详

Target tracking is a well studied topic in wireless sensor networks. It is a procedure that nodes in the network collaborate in detecting targets and transmitting their information to the base-station continuously, which leads to data implosion and redundancy. To reduce traffic load of the network, a data compressing based target tracking protocol is proposed in this work. It first incorporates a clustering based data gather method to group sensor nodes into clusters. Then a novel threshold technique with bounded error is proposed to exploit the spatial correlation of sensed data and compress the data in the same cluster. Finally, the compact data presentations are transmitted to the base-station for targets localization. We evaluate our approach with a comprehensive set of simulations. It can be concluded that the proposed method yields excellent performance in energy savings and tracking quality.
