Kinematically redundant manipulators have a number of potential advantages over current manipulator designs. For this type arm, velocity control through pseudoinverses is suggested. Questions associated with pseudoinverse are examined in detail and show that some cases leads to undesired arm configurations. A method for distributing joint angles good approximation true minimax criterion described. In addition several numerical considerations discussed.
How climate change in the middle to late Holocene has influenced early human migrations Central Asian Steppe remains poorly understood. To address this issue, we reconstructed a multiproxy-based history from sediments of Kanas Lake and neighboring Tiewaike southern Altai Mountains. The results show an exceptionally warm during ~6.5-3.6 kyr is indicated by silicon isotope composition diatom silica (δ30Sidiatom) biogenic (BSi) content. During 4.7-4.3 kyr, peak δ30Sidiatom reflects enhanced...
In recent years, the sustainable livelihood of farmers has been threatened by various events such as COVID-19 pandemic, which significantly impacted efforts to alleviate poverty. Therefore, it is vitally important increase farmers' resilience enhance stability and sustainability poverty alleviation efforts. this study, scientifically measure analyze resilience, we designed an analytical framework that captures characteristics from three dimensions buffer capacity, self-organization learning...
This paper is concerned with the determination of tight lower and upper bounds on expectation a convex function random variable. The classic are those Jensen Edmundson-Madansky were recently generalized by Ben-Tal Hochman. indicates how still sharper may be generated based simple idea sequentially applying to smaller subintervals range applicable in multivariate case if variables independent. In dependent inequality not available; however, developed using conditional form Jensen's...
The conflict between rapid economic development, resource mismatch, and ecological damage is growing more severe. Industrial structure upgrading, as a bridge activity the environment, crucial strategy for solving environmental problems. Based on mediating effect threshold models, this study selected 30 provincial panel data points in China from 2000 to 2020 impact of regulation technological innovation industrial upgrading. According findings, has “U” shaped upgrading passes three tests,...

Using panel data from 11 regions (9 provinces and two cities) in the Yangtze River Economic Belt (YREB) during 2002–2017, regional differences spatial characteristics of green efficiency water resources along YREB were analyzed. The undesirable outputs slacks-based measure-data envelopment analysis, Malmquist index, social network analysis models employed. A dynamic using a system generalized method moments model was established to empirically examine main factors influencing efficiency....
Influenced by the hydrogeological structure and other factors, change in groundwater depth shows seasonal fluctuation characteristics. Human activities have disrupted long-term stable pattern of change, which makes short-term prediction important. To cope with emergence scenarios, for first time, a discrete grey model fractional order accumulation is proposed this paper (FDGSM(1,1)). First, DGM(1,1) model, has relative advantage over fluctuating data, was chosen as basis transformation...
We present sharp bounds on the value of perfect information for static and dynamic simple recourse stochastic programming problems. The are sharper than available based Jensen's inequality. new use some recent extensions upper bound Edmundson-Madansky lower expectation a concave function several random variables. Bounds obtained nonlinear return functions linear strictly increasing utility When variables jointly dependent, type must be replaced by less “feasible point” bound. that constructs...
