This study presents a methodology designed to optimize various parameters of each access point within a Multiple-Input Single-Output (MISO) Visible Light Communication (VLC) system. The primary objective is to enhance both power and spectral efficiencies. A MISO-VLC model is presented based on experimental …

Background: In the Netherlands, general practitioners (GPs) play a key role in provider-initiated HIV testing, but opportunities for timely diagnosis are regularly missed. We implemented an educational intervention to improve HIV testing by GPs from 2015 to 2020, and observed a 7% increase in testing …

Sierra Leone faces significant challenges in providing comprehensive sexual and reproductive health care and rights (SRHR) due to cultural norms, poverty and limited health care resources. These issues disproportionately affect low-income women, who face multiple barriers to accessing essential SRHR …

The nonlinearity induced by light-emitting diodes in visible light communication (VLC) systems presents a challenge to the parametrization of orthogonal frequency division multiplexing (OFDM). The goal of the multi-objective optimization problem presented in this study is to maximize the transmitted …

Adolescents' access to contraception and other sexual and reproductive health (SRH) services has been described in previous studies as a problem to many communities in Africa. The Department of Health and HelpHer.org provides sexual and reproductive health services to adolescents in Esidadeni through …

ARS-CoV-2 can spread by close contact through large droplet spray and indirect contact via contaminated objects. There is mounting evidence that it can also be transmitted by inhalation of infected saliva aerosol particles. These particles are generated when breathing, talking, laughing, coughing or …

People with a visual impairment (PVI) often experience difficulties with wayfinding. Current navigation applications have limited communication channels and do not provide detailed enough information to support PVI. By transmitting wayfinding information via multimodal channels and combining these with …

Power usage is an important aspect of wireless acoustic sensor networks (WASNs) and reducing the amount of information that is to be transmitted is one effective way to save it. In previous contributions, we presented sensor selection as well as rate distribution methods to reduce the power usage of …

This paper deals with the networking implementation and optimizations for a VR and AR game with mocap suit, voice over IP and gameplay data like player information, lobby, etc. The logic for implementing these systems in the game is studied. First, there is a general description of the game so the reader …
