Conditions for prosperity and depression of a stochastic R&D model under regime switching

Abstract

The stochastic research and development (R&D) model plays an important role in economic growth theories. To explain the growth performance of the economy under regime switching, we first establish sufficient criteria that ensure economic prosperity, nonprosperity and depression in the R&D model disturbed by white and color noise. Then, we determine the threshold between prosperity and depression. Furthermore, we estimate an upper bound of the growth rates of technological progress and capital accumulation in the prosperity case. The results indicate that color noise sensitively impacts the growth performance of the economy in the R&D model. Finally, numerical simulations are conducted to verify our theoretical work.

Architectural Proposal for Low-Cost Brain–Computer Interfaces with ROS Systems for the Control of Robotic Arms in Autonomous Wheelchairs

“…Prior investigations have underscored the potential of BCIs in maneuvering both virtual entities and tangible objects, such as wheelchairs and quadcopters. Yet, the application of non-invasive BCIs in directing robotic limbs for reach and grasp endeavors poses significant hurdles [13,19].…”

“…Nonetheless, many retain the ability to generate neural signals pertinent to motor functions akin to those of unimpaired individuals. This revelation has propelled the exploration of BCIs as a nascent technology capable of decoding cerebral activity in real time, thereby facilitating anthropomorphic manipulation of prosthetic or exoskeletal assistive devices [19].…”
