Evaluation of the ecological status with benthic indices in the coastal system: the case of Bohai Bay (China)

Wenqian CAI,Wei MENG,Lusan LIU,Kuixuan LIN

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 5,   Pages 737-746 doi: 10.1007/s11783-013-0617-x

Abstract: from coastal areas of Bohai Bay (China) in April, 2008, three biotic indices (AZTI’s Marine Biotic Index(AMBI), Shannon–Wiener Index and -statistic) were applied together to evaluate the ecological statusmakers in visualizing spatial changes of organic pollutants in Bohai Bay, two indices, i.e., AMBI and Shannon-Wienerindex, were effective in distinguishing sites from Haihe River Estuary, Jiyun River Estuary and otherIn a word, AMBI, Shannon–Wiener Index and -statistic could be able to assess the benthic ecological

Sequential degradation-based burn-in test with multiple periodic inspections

Frontiers of Engineering Management 2021, Volume 8, Issue 4,   Pages 519-530 doi: 10.1007/s42524-021-0166-0

Abstract: Burn-in has been proven effective in identifying and removing defective products before they are delivered to customers. Most existing burn-in models adopt a one-shot scheme, which may not be sufficient enough for identification. Borrowing the idea from sequential inspections for remaining useful life prediction and accelerated lifetime test, this study proposes a sequential degradation-based burn-in model with multiple periodic inspections. At each inspection epoch, the posterior probability that a product belongs to a normal one is updated with the inspected degradation level. Based on the degradation level and the updated posterior probability, a product can be disposed, put into field use, or kept in the test till the next inspection epoch. We cast the problem into a partially observed Markov decision process to minimize the expected total burn-in cost of a product, and derive some interesting structures of the optimal policy. Then, algorithms are provided to find the joint optimal inspection period and number of inspections in steps. A numerical study is also provided to illustrate the effectiveness of our proposed model.

A total torque index for dynamic performance evaluation of a radial symmetric six-legged robot

Kejia LI, Xilun DING, Marco CECCARELL

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 2,   Pages 219-230 doi: 10.1007/s11465-012-0320-9

Abstract:

This article focuses on the dynamic index and performance of a radial symmetric six-legged robot.A novel index of total torque is proposed by considering the posture of the supporting legs.The new index can be used to optimize the leg’s structure and operation for consuming minimum powerMain influences are outlined as well as the usefulness of the proposed performance index.
