Global dissipativity analysis for delayed quaternion-valued neural networks.

Neural networks : the official journal of the International Neural Network Society
The problem of global dissipativity analysis for quaternion-valued neural networks (QVNNs) with time-varying delays is firstly investigated in this paper. The QVNN is studied as a single entirety without any decomposition. Several algebraic condition...

Filtering of Discrete-Time Switched Neural Networks Ensuring Exponential Dissipative and $l_{2}$ - $l_{\infty }$ Performances.

IEEE transactions on cybernetics
This paper studies delay-dependent exponential dissipative and l - l filtering problems for discrete-time switched neural networks (DSNNs) including time-delayed states. By introducing a novel discrete-time inequality, which is a discrete-time versio...

Bio-inspired vision based robot control using featureless estimations of time-to-contact.

Bioinspiration & biomimetics
Marvelous vision based dynamic behaviors of insects and birds such as perching, landing, and obstacle avoidance have inspired scientists to propose the idea of time-to-contact, which is defined as the time for a moving observer to contact an object o...

Stability analysis of delayed neural networks via a new integral inequality.

Neural networks : the official journal of the International Neural Network Society
This paper focuses on stability analysis for neural networks systems with time-varying delays. A more general auxiliary function-based integral inequality is established and some improved delay-dependent stability conditions formulated in terms of li...

Hybrid methodology for tuberculosis incidence time-series forecasting based on ARIMA and a NAR neural network.

Epidemiology and infection
Tuberculosis (TB) affects people globally and is being reconsidered as a serious public health problem in China. Reliable forecasting is useful for the prevention and control of TB. This study proposes a hybrid model combining autoregressive integrat...

Multi-Robot Coalitions Formation with Deadlines: Complexity Analysis and Solutions.

PloS one
Multi-robot task allocation is one of the main problems to address in order to design a multi-robot system, very especially when robots form coalitions that must carry out tasks before a deadline. A lot of factors affect the performance of these syst...

Reducing false arrhythmia alarm rates using robust heart rate estimation and cost-sensitive support vector machines.

Physiological measurement
To lessen the rate of false critical arrhythmia alarms, we used robust heart rate estimation and cost-sensitive support vector machines. The PhysioNet MIMIC II database and the 2015 PhysioNet/CinC Challenge public database were used as the training d...

Robot-assisted laparoscopic pyeloplasty in infants using 5-mm instruments.

Journal of pediatric urology
BACKGROUND: Utilization of the robotic approach to pyeloplasty continues to grow in the field of pediatric urology. Adoption in the infant population has perhaps been the slowest because of the limited operative domain and relatively large instrument...

Elimination of spiral waves in a locally connected chaotic neural network by a dynamic phase space constraint.

Neural networks : the official journal of the International Neural Network Society
In this study, a method is proposed that eliminates spiral waves in a locally connected chaotic neural network (CNN) under some simplified conditions, using a dynamic phase space constraint (DPSC) as a control method. In this method, a control signal...

Feasibility and safety of early lower limb robot-assisted training in sub-acute stroke patients: a pilot study.

European journal of physical and rehabilitation medicine
BACKGROUND: So far, the development of robotic devices for the early lower limb mobilization in the sub-acute phase after stroke has received limited attention.
