Networks performance is traditionally evaluated using packet delivery ratio (PDR) and latency (delay). We propose an addition mechanism the drop-burst length (DBL). Many traffic classes display varying application-level performance according to the pattern of drops, even if the PDR is similar. In this paper we study a number of VANET scenarios and evaluate them with these three metrics.Vehicular Ad-hoc Networks (VANETs) are an emerging class of Mobile Ad-hoc Network (MANETs) where nodes include both moving vehicles and fixed infrastructure. VANETs aim to make transportation systems more intelligent by sharing information to improve safety and comfort. Efficient and adaptive routing protocols are essential for achieving reliable and scalable network performance. However, routing in VANETs is challenging due to the frequent, high-speed movement of vehicles, which results in frequent network topology changes.Our simulations are carried out using NS2 (for network traffic) and SUMO (for vehicular movement) simulators, with scenarios configured to reflect real-world conditions. The results show that OLSR is able to achieve a best DBL performance and demonstrates higher PDR performance comparing to AODV and GPSR under low network load. However, with GPSR, the network shows more stable PDR under medium and high network load. In term of delay OLSR is outperformed by GPSR.

High speed torque is very important in tennis batting process , this paper discusses the shoulder and torso rotation torque generated by the weight of tennis sports influence. Taking 48 tennis players as research objects, the rotation torque of professional tennis players are relatively outstanding with performance value,so we concluded that in the case of keeping the torso erect and through the process optimization of the rotation, we could combined shoulder movement and body bottom-up movement. These results suggested that some given hitting model can not only increase the performance of the tennis player on the pitch, but also reduce the risk of causing excessive damage.

This study assesses the overall impact of job creation associated with the anticipated construction of a high-speed rail (HSR) network in the United States, particularly in California, which was scheduled to begin construction as early as September 2012. Using variations of a bottom-up construction estimation technique, the study provides estimates of the quantity and type of workers needed during the design, construction, and operation of high-speed rail infrastructure, as well as education and training needs and level of this forecasted workforce. Given the high profile of state and national commitment to HSR initiatives, as well as its potential opportunity to generate employment, a comprehensive analysis that discusses the education, training, and attendant needs produced during the creation of HSR networks is timely. By using a refined bottom-up approach to estimate labor, education, and training needs required for the California HSR network, and with general application of this model across assessment of other corridors, this report seeks to identify the magnitude of workforce development challenges that lie ahead in the implementation of national HSR systems.
