DARPA Robotics Grand Challenge Participation and Ski-Type Gait for Rough-Terrain Walking Article

Hongfei Wang, Shimeng Li, Yuan F. Zheng

Engineering 2015, Volume 1, Issue 1, Pages 36-45 doi: 10.15302/J-ENG-2015006

Abstract: We also introduce a new gait for humanoid robot locomotion to improve stability performance, called theSki-Type gait.We analyze the stability performance of this gait and use the stability margin to choose between twoNext, we perform a force/torque analysis for the redundant closed-chain system in the Ski-Type gait,Finally, we compare our experimental results with biped walking to validate the Ski-Type gait.

Odour reducing microbial-mineral additive for poultry manure treatment

Kajetan Kalus, Sebastian Opaliński, Devin Maurer, Somchai Rice, Jacek A.Koziel, Mariusz Korczyński, Zbigniew Dobrzański, Roman Kołacz, Beata Gutarowska

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 3, doi: 10.1007/s11783-017-0928-4

Abstract: Poultry production systems are associated with emissions of odorous volatile organic compounds (VOCs), ammonia (NH ), hydrogen sulfide (H S), greenhouse gases, and particulate matter. Development of mitigation technologies for these emissions is important. Previous laboratory-scale research on microbial-mineral treatment has shown to be effective for mitigation of NH , H S and amines emissions from poultry manure. The aim of this research was to assess the effectiveness of surface application of a microbial-mineral treatment for other important odorants, i.e., phenolics and sulfur-containing VOCs. Microbial-mineral litter additive consisting of 20% (w/w) of bacteria powder (six strains of heterotrophic bacteria) and 80% of mineral carrier (perlite-bentonite) was used at a dose of 500 g?m (per ~31 kg of manure). Samples of air were collected in two series, 4 and 7 days after application of additives. An odor profile of the poultry manure was determined using simultaneous chemical and sensory analysis. Reduction levels of VOCs determined on Day 4 was between 31% and 83% for mineral adsorbent treatment and in the range of 9% and 96% for microbial-mineral additive, depending on the analyzed compound. Reduction levels on Day 7 were considerably lower than on Day 4, suggesting that the odorous VOCs treatment efficacy is relatively short. There was no significant difference between treatments consisting of microbial-mineral additive and mineral carrier alone.

Real prospects for the development of power technologies based on renewable energy sources in Poland

Sławomir DYKAS, Artur SZYMAŃSKI, Xiaoshu CAI

Frontiers in Energy 2017, Volume 11, Issue 2, Pages 168-174 doi: 10.1007/s11708-017-0474-6

Abstract: In Poland more than 40% of the power units have been operating for over 40 years now and more than 10% are over 50 years old, which indicates a high degree of decrease in the value of the energy sector. An analysis of the energy market shows that every year a new power plant should be built with a capacity of 1000 MW to ensure the national energy security. An energy market research indicates that in Poland the structure of energy production is changing in recent years—the share of fossil (solid) fuels in electricity and heat production was approximately 88% in 2009, while in 2004 it reached 93%. According to the analysis of the market, it can be seen that conventional energy, mainly based on coal and lignite, has been the most important segment of the sector for a long time.?In this paper the prospects for the development of power technologies based on renewable energy sources (RES) in Poland are presented.
