• A simple methodology is provided to deal with 3D block-cutting and 3D mesh cutting.
• An open-source MATLAB toolbox is provided.
• The strategy avoids delicate error control because it only deals with convex bodies.
• Commonly used ...

This study presents a simple approach and its associated MATLAB toolbox for 3D block cutting and mesh cutting. The approach is suitable for the meshes of numerical methods including the Key Block Theory (KBT), the Discontinuous Deformation ...

The application of Topology Optimisation (TO) to help in the manufacture of metallic components in highly technological industries has increased recently. To equally benefit from TO, the construction industry must address its specific issues, such ...

Compound faults inevitably occur in multi-joint industrial robots resulting in excessive vibration. Intelligent diagnosis for the occurrence and position of fault joints can efficiently reduce the maintenance cost. Compared with laboratory ...

• A robot joint diagnosis method with compound fault decoupling is proposed.
• An attractive and valuable diagnostic framework RJGFD is proposed.
• Novel multi-joint attention residual network (MJAR) is designed.
• MJAR can detect and ...

The integrated joint has a broad application prospect in the field of cooperative robots. In this paper, aiming at the problem of joint temperature rising under universal joint rating, a series of research on joint temperature distribution and ...

The objective of this study is to implement a new simplified model of a muscle, based on a 1D element, rod type, used in most common analysis, instead of a 3D mesh of the muscle geometry. The main advantages of this new method for modeling muscles is ...

The main objective of this paper is to perform design sensitivity analysis of two right angle coupled plates, connected by various joint connections, to determine an optimum coupling loss factor (CLF) using optimization in the statistical energy ...

This column is devoted to a review of the recent dramatic developments on many fronts of combinatorial (and computational) geometry, caused by the introduction of techniques from algebra and algebraic geometry, pioneered by Guth and Katz about 10 years ...

We present mathematical models for joints, springs, dashpots and follower loads, to be used together with geometrically-exact beam finite elements to simulate mechanisms. The rotations are described using Rodrigues parameters. An updated-Lagrangian ...

Let L 1 , L 2 , L 3 be finite collections of L 1 , L 2 , L 3 , respectively, lines in R 3 , and J ( L 1 , L 2 , L 3 ) the set of multijoints formed by them, i.e. the set of points x R 3 , each of which lies in at least one line l i L i , for all i = 1 , ...

In this paper we study how the visual animation of a self-avatar can be artificially modified in real-time in order to generate different haptic perceptions. In our experimental setup, participants could watch their self-avatar in a virtual environment ...

Capturing the skeleton motion and detailed time-varying surface geometry of multiple, closely interacting peoples is a very challenging task, even in a multicamera setup, due to frequent occlusions and ambiguities in feature-to-person assignments. To ...

This paper addresses, in the context of wireless network design, the problem of optimally partitioning the spectrum into a set of nonoverlapping channels with nonuniform spectrum widths. While narrower bands split the total available spectrum into more ...

Determining anomalies in data streams that are collected and transformed from various types of networks has recently attracted significant research interest. Principal component analysis (PCA) has been extensively applied to detecting anomalies in ...

The performance of wireless networks can be enhanced by performing network coding on the intermediate relay nodes. To enhance the throughput of large wireless networks, we can decompose them into a superposition of simple relay networks called two-hop ...

This paper presents a novel method for performing efficient cost aggregation in stereo matching. The cost aggregation problem is reformulated from the perspective of a histogram, giving us the potential to reduce the complexity of the cost aggregation ...

Learning in nonstationary environments, also known as learning concept drift, is concerned with learning from data whose statistical characteristics change over time. Concept drift is further complicated if the data set is class imbalanced. While these ...

This paper presents the first method for full-body trajectory optimization of physics-based human motion that does not rely on motion capture, specified key-poses, or periodic motion. Optimization is performed using a small set of simple goals, for ...

Three-dimensional surface registration transforms multiple three-dimensional data sets into the same coordinate system so as to align overlapping components of these sets. Recent surveys have covered different aspects of either rigid or nonrigid ...

This paper proposes a novel representation of articulated human actions and gestures and facial expressions. The main goals of the proposed approach are: 1) to enable recognition using very few examples, i.e., one or k-shot learning, and 2) meaningful ...

This manuscript considers the following “graph classification” question: Given a collection of graphs and associated classes, how can one predict the class of a newly observed graph? To address this question, we propose a statistical model for graph/...
