In current large-scale distributed key-value stores for cloud computing, the tail latency of the hundreds of key-value accesses generated by an end-user request determines the response time of this request. Replica selection algorithms, which select the best replica server for each key-value access as much as possible, is crucial to reduce the tail latency.(More)
OBJECTIVE To compare and evaluate the effect of PFNA-II and PFNA for the treatment of femoral intertrochanteric fracture. METHODS From August 2009 to August 2012, 238 patients with intertrochanteric fracture in Department of Orthopedics, Affiliated Jiangsu Shengze Hospital of Nanjing Medical University treated with PFNA-II (n=112) and PFNA (n=126) were(More)
In current large-scale distributed key-value stores, a single end-user request may lead to key-value access across tens or hundreds of servers. The tail latency of these key-value accesses is crucial to the user experience and greatly impacts the revenue. To cut the tail latency, it is crucial for clients to choose the best replica server as much as(More)
The treatment chair includes a chair-seat and a chair-back from mechanics, which are both controlled by a linear actuator respectively. Thus, after the mechanical principle of the treatment chair is introduced, we present a control system and its control schematics in detail. Functionally, the control system takes advantage of all buttons on the control(More)
An impeller plays a significant role in the non-invasive ventilator. This paper shows a model of impeller for noninvasive ventilator established with the software Solidworks. The model was studied for feasibility based on ANSYS. Then stress and strain of the impeller were discussed under the external loads. The results of the analysis provided verification(More)
