In this paper we propose novel methods for completion (from limited samples) and de-noising of multilinear (tensor) data as an application consider 3-D 4- D (color) video de-noising. We exploit the recently proposed tensor-Singular Value Decomposition (t-SVD)[11]. Based on t-SVD, notion rank a related tensor nuclear norm was in [11] to characterize informational structural complexity data. first show that videos with linear camera motion can be represented more efficiently using t-SVD...
Tensor robust principal component analysis (PCA) approaches have drawn considerable interests in many applications such as background subtraction, denoising, and outlier detection, etc. In this paper we propose an online tensor PCA where the multidimensional data (tensor) is revealed sequentially mode, updated based on latest estimation newly collected data. Compared to batch significantly reduce required memory improve computation efficiency. Application fusing cloud-contaminated satellite...
In this paper a new dictionary learning algorithm for multidimensional data is proposed. Unlike most conventional methods which are derived dealing with vectors or matrices, our algorithm, named KTSVD, learns directly via novel algebraic approach tensor factorization as proposed in [3, 12, 13]. Using one can define tensor-SVD and we propose to extend K-SVD used 1-D K-TSVD handling 2-D 3-D data. Our based on the idea of sparse coding (using group-sparsity over coefficient vectors), alternates...
A sustainable irrigation system is known to improve the farmland soil water-salt environment and increase crop yields. However, use of saline water under proper drainage measures still needs further study. In this study, a two-year experiment was performed assess effects subsurface condition. coupled model consisting HYDRUS-2D EPIC module used investigate salinity (IWS) depth (SDD) on content summer maize yield when adopted for different measures. Summer in experiments were irrigated with...
The low permeability of soil and high investment salt management pose great challenges for implementation land reclamation in coastal areas. In this study, a temporary leaching system was tested which bundled maize straw (straw drainage module, SDM) operated as subsurface tube diluted seawater used leaching. A preliminary field experiment conducted soil-filled lysimeters to examine the system’s feasibility numerical model (HYDRUS-3D) based on measured data designed simulate entire process....
Brackish water has been utilized extensively in agriculture around the world to cope with global deficit, but soil salt accumulation caused by brackish irrigation cannot be ignored. Straw incorporation confirmed an effective sustainable means inhibit accumulation. An experiment was conducted growth tanks over two consecutive growing seasons investigate effects of wheat straw on moisture and salinity under (5g NaCl L−1). Furthermore, trial investigated three cutting lengths (CK = 0 cm; L1 5...
The freshwater deficit is the major constraint to winter wheat production. Saline water irrigation could alleviate stress while increasing risk of soil salinization, which would result in yield reduction due additional salt stress. objective present study explore effect a straw-returning mode promote production under saline irrigation. A field experiment was conducted during growing seasons 2017–2018 and 2018–2019. Four returning modes were set, based on an equivalent carbon input: straw...
Secondary salinization induced by brackish water irrigation has forced agricultural development to increasingly rely on soil management. A two-year field experiment was conducted explore the effects of different straw incorporation rates (SIRs) within 0 20 cm topsoil water–salt balance, maize yield production, and use efficiency (WUE) under in a naturally non-saline area. Air-dried wheat applied at 0, 4.5, 9.0, 13.5, 18.0 t ha−1 (R0–R4) two salinity levels with salt content 1.92 dS m−1 (SL)...
Robotic grippers, which act as the end effector and contact objects directly, play a crucial role in performance of robots. In this paper, we design analyze new robotic gripper based on braided tube. Apart from deployability, self-forcing mechanism, i.e., holding force increases with load/object weight, facilitates tube to grasp different shapes, weights, rigidities. First, taking cylindrical object an example, mechanism is theoretically analyzed, explicit formulas are derived estimate...
