In this paper, we investigate the per-tier outage probability of multiuser multiple-input multiple-output (MU-MIMO) transmissions in heterogeneous networks (HetNets) with joint interference constraint. tier cellular cell, user equipment (UE) is required to report measured channel information and base station (BS) adopts ZF-based precoding MU-MIMO transmission achieve diversity gain. With constr...

Dynamic psychological processes are most often assessed using self-report instruments. This places a constraint on how often and for how long data can be collected due to the burden placed on human participants. Smartphones are ubiquitous and highly personal devices, equipped with sensors that offer an opportunity to measure and understand psychological processes in real-world contexts over the...

Striking a moving object such as a flying ball to a target location is a highly skillful maneuver that a human being has to learn through a great deal of practice. In robotic manipulation, precision batting remains one of the most challenging tasks in which computer vision, modeling, planning, control, and action must be tightly coordinated in a split second. This paper investigates the problem...

This paper studies the transient and steady performance constraints on flexible joint manipulator system with exogenous disturbance, proposes a fixed-time prescribe tracking control method based singular perturbation model. For fast subsystem, subcontroller superior is proposed that guarantees suppression of vibration in fixed-time. The remaining slow subsystem can be linked rigid methods to ac...

Introduction: Elderly patients suffer disproportionally from a number of chronically painful conditions, with arthritis leading the list. Osteoarthritis (OA) is the most common joint disorder and the most prevalent cause of joint pain across the spectrum of middle age to elderly. Enhancing behavioral intention toward self-care for OA, previously known as proximal predictor of self-care, is one ...
