There are lots of handicaps and elders in the world. Many of them are not able to move as easily as normal people. It will be very useful if we develop an automatic wheelchair to help them moue more freely. In this paper we will propose a design of small-area automatic wheelchair to help handicaps OT elders be able to moue easily in a small area. The most concern in this project is low cost with acceptable performance rather than high velocity OT higrk accuracy. The design antegrates several technologies to apply on the wheelchair, including wireless positioning. automatic mobile technology: and wireless communication. On the oth,er hand, we propose a design that duplicable information can be computed on senier side, and information which is not duplicable can be computed in constant time. Therefore, our design of small-area automatic wheelchair can cost very low. W e will also propose a design of building map infonation to make the whole design more complete.
Infant hydrocephalus poses a severe global health burden; 80% of cases occur in the developing world where patients have limited access to neurosurgical care. Surgical treatment combining endoscopic third ventriculostomy and choroid plexus cauterization (ETV/CPC), first practiced at CURE Children’s Hospital of Uganda (CCHU), is as effective as standard ventriculoperitoneal shunt (VPS) placement while requiring fewer resources and less post-operative care. Although treatment focuses on controlling ventricle size, this has little association with treatment failure or long-term outcome. This study aims to monitor the progression of hydrocephalus and treatment response, and investigate the association between cerebral physiology, brain growth, and neurodevelopmental outcomes following surgery. We will enroll 300 infants admitted to CCHU for treatment. All patients will receive pre/post-operative measurements of cerebral tissue oxygenation (SO2), cerebral blood flow (CBF), and cerebral metabolic rate of oxygen consumption (CMRO2) using frequency-domain near-infrared combined with diffuse correlation spectroscopies (FDNIRS-DCS). Infants will also receive brain imaging, to monitor tissue/ventricle volume, and neurodevelopmental assessments until two years of age. This study will provide a foundation for implementing cerebral physiological monitoring to establish evidence-based guidelines for hydrocephalus treatment. This paper outlines the protocol, clinical workflow, data management, and analysis plan of this international, multi-center trial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
