In this thesis, focus on the wireless links between devices equipped by deployed operating personnel and intermediary access point infrastructure. We use multi-radio (MR) platforms, wireless devices with multiple and diverse transceiver technologies, to produce robust and reliable links through adaptive control of available transceivers. Primarily, we study the application of intelligent control techniques, namely reinforcement learning (RL), for adaptive control over diverse transceivers to achieve the desired robustness and reliability under dynamic environmental conditions.

The aim of this study is to enhance biogas production from the organic fraction of municipal solid waste (OFMSW) and garden waste (GW) via pretreatment and codigestion. In order to achieve the aims of the study, two objectives have been developed and are outlined below: To investigate an optimum co-digestion mixture of OFMSW with untreated and pretreated GW; to investigate the effectiveness of different pretreatments on the potential for biogas production from GW and to identify the relationship between certain changes in GW characteristics and enhanced yield.

The growth of waterborne pathogens and the discharge of partially treated or non-treated chemical waste has become a severe environmental and health risk. Conventional wastewater treatment methods have become less effective, and most current techniques require multiple stages for the disinfection of antimicrobial-resistant (AMR) pathogens and the combined removal of toxic, non-biodegradable, or emerging priority pollutants from wastewater.
