In-flight alignment method of navigation system based on microelectromechanical systems sensor measurement
Published 2019-04-01“…Inertial navigation systems based on microelectromechanical systems (MEMS) sensors offer advantages that include small size, light weight, low power consumption, strong environmental adaptability, and low cost. These advantages make these sensors particularly suitable for application to precision-guided munitions, which commonly have poor launching environments, strict volume and power consumption requirements, and high cost sensitivity. …”

Migrant Shepherds: Opportunities and Challenges for Mediterranean Pastoralism
Published 2017-02-01“…In several south European countries, foreign workers (shepherds who have emigrated from other Mediterranean countries) play an important role in this process because they provide skilled labour at a relatively low cost. Such migratory flows enable the pursuit, evolution and diversification of an activity increasingly acknowledged as essential to the preservation of the region’s natural and cultural heritage; and yet, it is one that Europeans are practising less and less.Engaging this workforce in the process of adapting and innovating the sector by integrating and empowering them provides the opportunity to help train the shepherds and the breeders of tomorrow. …”

Two-hop cover-based access control scheme for wireless sensor networks
Published 2010-01-01“…In order to support randomly moving users,a THC（two-hop cover） algorithm and a two-hop cover-based ac-cess control scheme were proposed.The proposed algorithm made two-hop nodes be able to retrieve access control in-formation of user’s in time through diffusing the information periodically.The scheme based on THC algorithm,the se-curity mechanisms of Merkle hash tree and one way chain,as well as distributed access control mode,its main contribu-tion was it supports randomly moving users for the first time.The analyses and experiments have shown that the pro-posed scheme can be applied to both mobile and stationary user and have several advantages over the current access con-trol methods of low cost in computation,communication and storage,and resistance to node capture,query replay and DoS attacks.…”

Research on 5G service coverage capability before 4G carrier re-farming to 5G
Published 2023-03-01“…In order to build a low-cost and high-efficiency 5G low-frequency network, it is necessary to study the best plan of plowing low-frequency 3G and 4G networks into 5G in advance.Under the condition of no ideal low frequency 5G test environment due to no re-farming, the coverage capacity after re-farming was estimated through theoretical analysis and was indirectly verified based on the current network test data.The key setting of link budget and model selection were discussed, the rationality of the estimation results was indirectly verified by the actual test data.The conclusion had been actually applied to the planning scheme of a major operator for the national 900 MHz network, which has essential reference significance to guide the network refarming.…”

Research and implementation of pedestrian detection technology based on smart road
Published 2019-09-01“…Aiming at the problem of single detection function,higher cost and lower detection efficiency and reliability for current pedestrian detection,which was mostly realized by vehicle mounted equipment,a pedestrian detection technology based on smart road was proposed.By deploying a large number of low-cost,highly reliable Internet of things devices on the road,real-time detection of pedestrian information in the surrounding environment was realized.Early warning information can be provided to vehicles with very low latency wireless communication technology,which can improve road safety.At present,the prototype of the pedestrian detection system has been developed,and verified by field test,the pedestrian detection system can detect pedestrians effectively.Within the detection range of 4 meters,the accuracy of single device can reach 80%,and the accuracy of multiple cross-deployed devices can reach 100%.…”
