The Underwater Projectile Launching Process Prediction Based on Reduced Order Method by Ke Deng, Yi Jiang, Huan-Xing Liu

“…In this paper, computational fluid dynamics (CFD) and reduced order method (ROM) are developed for predicting the velocity time series during the initial stage of projectile launching. The overlapping grid technique is firstly applied to perform high accuracy CFD simulations of the underwater launch of a submarine-launched projectile under two-parameter varying working conditions (i.e., different piston velocities and pipe interface radii). …”

Geo Bogza și provincia ca aventură – note despre O sută șaptezeci și cinci de minute la Mizil by Paul Cernat

“…Unlike the minor or satiric prose about the Romanian townlets of 1900, Bogza’s piece of writing is regarded as a form of paradoxical rehabilitation of the provincial anonymity by a grid partly indebted to the vanguard. Without ceasing to represent a space of failure and unfulfillment, the province thus becomes a space of unusual experiences and of existential adventure, in agreement with the authenticist literature of the generation of the thirties.…”

Study on Yaw Gearbox Broken Tooth of MW-class Wind Turbine by Wang Fugang, Cheng Linzhi, Su Fengyu, Xie Jinjuan, Tong Shiwei, Li Chengchen, Zhuo Ran, Li Yongkui

“…The output pinion of a MW-class wind turbine yaw gearbox has been broken down after about3 years in the grid. The comprehensive analysis is carried out on the failure gears,the causes of gear damage,such as tooth fracture,design factor,production factor,factors of assembly and operation,system protection factor,etc. are analyzed one by one,the final positioning between the thrust pad bearing and yaw ring interference is the direct cause. …”

Interference coexistence between wireless meter reading system in 470～510 MHz band and adjacent systems by Ruichen XU, Ji FANG, Hao DU, Xiaobo WANG

“…Current RF specification restrains the wireless meter reading system (WMRS) working in 470～510 MHz band.It is incapable of meeting new communication speed and coverage requirements of power network.Under the premise of ensuring that prior used communication systems in adjacent band work without interference,how to modify the related RF specification to improve communication ability of WMRS is one of the problems to be solved at present.Firstly,the domestic frequency spectrum allocation in 450～566 MHz band was analyzed.Then,based on RF parameters of 3 kinds of WMRS from State Grid and deterministic computation and ray tracing simulation method,the interference coexistence between the WMRS and adjacent communication systems,which including broadcast television system,CDMA450 system,railway train dispatching system and FDD-LTE system was studied.At last,some suggestions for revision of relevant RF specifications were obtained.…”

De la multifonctionnalité des Coopératives d’activités et d’emploi : des modèles socioproductifs expérimentaux dans les zones grises de l’emploi et du travail by Justine Ballon

“…This research with scientific, pedagogical and operational aims lead to an original approach of integral participatory action research, an analysis grid, those of the socio-productive models of the BEC, an activity-based approach to work revealing a dual process of empowerment and democratisation, a reading of the complexity of the social relations of production with the cooperative relationship of activities and finally an exploratory definition of the multifunctionality of the BEC.…”

Noncoherent multiple symbol detection of CPFSK based on decision-feedback by Qiang CHEN, Guo-sheng RUI, Wen-jun SUN, Wen-biao TIAN, Yang ZHANG

“…Specifically, the form is a union bound which consists of being tight at high SNR and being tight at low SNR, the latter can be obtained by grid minimum Euclidean distance. Theoretical analysis and si-mulation results show that compared with the traditional algorithm, the improved algorithm could keep no loss of detec-tion performance, but the complexity is reduced at negative exponent power way with the increase of number of feedback element.…”
