Background. CD4+ T-lymphocyte monitoring is not routinely available in most resource-limited settings. We investigated predictors of time to CD4+ T-lymphocyte recovery in HIV-infected children on highly active antiretroviral (HAART) at Korle-Bu Teaching Hospital, Ghana. Methods. Time to CD4+ T-lymphocyte recovery was defined as achieving percent CD4+ T-lymphocytes of 25%. We used Cox proportion...
Sustainability assessment of resource recovery from waste is an important prerequisite for informed and sound decision-making. Life Cycle Sustainability Assessment (LCSA) has been developed to support this process, yet its use is still constrained by the difficulty of identifying the most relevant impact parameters. This paper, seeks to inform LCSA for resource recovery from waste based on a pa...
the purpose of this research was to evaluate the recovery potential of solid waste in mashhad. the solid waste generated in the regions 4, 5 and 6 has been quantified and characterized using direct weighing, physical testing and truckload sampling methods. to determine the quantity and quality of waste generated and its seasonal variations, chemical and physical analysis were carried out for on...
The goal of the guarded software upgrading (GSU) framework is to minimize mission performance loss due to onboard software upgrading activities and that due to system failure caused by residual faults in an upgraded version. We exploit inherent system resource redundancies as the means of fault tolerance to meet the development cost and onboard resource constraints. Furthermore, we devise a mes...
Microbial biotechnology is essential for the development of circular economy in wastewater treatment by integrating energy production and resource recovery into the production of clean water. A comprehensive knowledge about identity, physiology, ecology, and population dynamics of process-critical microorganisms will improve process stability, reduce CO2 footprints, optimize recovery and bioene...
BACKGROUND Psychosocial interventions have an important role in promoting recovery in people with persisting psychotic disorders such as schizophrenia. Readily available, digital technology provides a means of developing therapeutic resources for use together by practitioners and mental health service users. As part of the Self-Management and Recovery Technology (SMART) research program, we hav...
Dynamic resource management is a crucial part of the infrastructure for emerging mission-critical distributed real-time embedded system. Because of this, the resource manager must be fault-tolerant, with nearly continuous operation. This paper describes an ongoing effort to develop a fault-tolerant multi-layer dynamic resource management capability and the challenges we have encountered, includ...
Many complex systems demand manifold resources to be supplied from distinct channels to function properly, e.g., water, gas, and electricity for a city. Here, we study a model for viability of such systems demanding more than one type of vital resource be produced and distributed by resource nodes in multiplex networks. We found a rich variety of behaviors such as discontinuity, bistability, an...
Reliable data transmission is desirable in wireless sensor networks due to the high packet loss rate during multi-hop transmissions. To reliably transmit data for event-driven applications, packet loss recovery mechanism is needed. For loss recovery, sensor nodes need to keep packets in their buffers until transmissions successfully complete. However, since sensor nodes have limited memory, pac...
Cloud computing has been widely applied to a wide variety of computing environments, with the traditional distributed computing environment, cloud computing using virtual machines to achieve dynamic resource partitioning. Checkpoint recovery technology is a low-cost method to improve the system availability. This paper analyzes the characteristics of cloud computing, virtualization technology a...
