Hybrid particle swarm optimization with spiral-shaped mechanism for solving high-dimension problems

Particle swarm optimization (PSO) is a well-known metaheuristic, whose performance for solving global optimization problems has been thoroughly explored. It has been established that without proper manipulation of the inertia weight parameter, the search for a global optima may fail. In order to handle this problem, we investigate the experimental performance of a PSO-based metaheuristic known as HPSO-SSM, which uses a logistic map sequence to control the inertia weight to enhance the diversity in the search process, and a spiral-shaped mechanism as a local search operator, as well as two dynamic correction factors to the position formula. Thus, we present an application of this variant for solving high-dimensional optimization problems, and evaluate its effectiveness against 24 benchmark functions. A comparison between both methods showed that the proposed variant can escape from local optima, and demonstrates faster convergence for almost every evaluated function

DESENVOLVIMENTO DE UMA TECNOLOGIA MHEALTH PARA PREVENÇÃO E LITERACIA EM SAÚDE MENTAL ENTRE JOVENS UNIVERSITÁRIOS

The theme of this paper is the development of a mobile technology application for health promotion in the context of the Public University. This is an applied research that presents the stages of construction and designer of a mhealth technology. The work is guided by interdisciplinary theoretical reflection, covering fundamentals of communication, psychology and computing. Through the analysis of interviews and suggestions from students of the institution, a software project was built to prevent illness and promote mental health. The proposal is of fundamental importance and can contribute to the development of practices that mitigate mental suffering in the context of public Higher Education.El tema de este trabajo es el desarrollo de una aplicación tecnológica móvil para la promoción de la salud en el contexto de la Universidad Pública.
