Path Planning and Optimization of Humanoid Manipulator in Cartesian Space

An improved bi-directional randomly growing random tree algorithm based on greedy growth plan in 3D space is recommended to solve the challenges of poor performance and multi-solvability of humanoid manipulator Cartesian space path planning in physical human-robot communication. The workspace of a manipulator established by Monte Carlo is used as the sampling space of the rapidly growing random tree, while the opposite growing greedy growth strategy is introduced in the random tree expansion process to improve the route planning's effectiveness.

MCPS: a mapping method for MAERI accelerator base on Cartesian Product based Convolution for DNN layers with sparse input feature map

Deep learning's high success in many domains, such as image and voice detection, has resulted in use in various fields such as image and voice classification. DNN accelerators have soared success by capitalizing on trends such as data reuse and sparsity. However, the accelerators that are specifically designed to exploit the data scarcity are usually non-reconfigurable and have finite dataflow. This paper presents a new dataflow for the MAERI, called Channel Dimension Stationary. It can be used for convolutional layers that have no input feature maps. We updated the mRNA tool, which includes an energy and performance analyzer of the mapping project in MAERI, to analyze the mapping based on CDS dataflow. The proposed mapping in the case of 50%, 70%, and 90% of the country's poorest ifmaps shows that the improved energy savings can increase energy efficiency by 3x, 6x, and 13x respectively, with no apparent decrease in utilization.

2-Cartesian Fibrations I: A Model for $$\infty $$ ∞ -Bicategories Fibred in $$\infty $$ ∞ -Bicategories

We show the existence of a left proper combinatorial simplicial model category whose fibrous forms are precisely the 2-Cartesian fibrations arranged over a selected scaled simplicial unit S. This gives a new model structure modeling 2̆21e u221e-bicategories, which we show is Quillen equivalent to Lurie's scaled simplicial set model, which is the equivalent to Lurie's scaled simplicial set model. This characterization then helps us to identify those 2-Cartesian fibrations that formed as the cohesive nerve of a Set^+_0̆394 Set u0394+ enriched categories, showing that our definition refreshes the preexisting notions of fibred 2-categories.

Cartesian to geodetic coordinates conversion on a triaxial ellipsoid using the bisection method

On a triaxial ellipsoid, a new method to convert Cartesian coordinates to geodetic coordinates is given. After the computation of the foot distance, an analytical and a numerical approach and the geodetic height by the Euclidean distance are used to determine the geodetic latitude and longitude. The new numerical technique is confirmed by numerical experiments for several ellipsoids with different eccentricities, and then is compared to Ligas, Chen et al.
