There's a widely known need to revise current forms of healthcare provision. Of particular interest are sensing systems in the home, which have been central several studies. This article presents an overview this rapidly growing body work, as well implications for machine learning, with aim uncovering gap between state art and broad needs services ambient assisted living. Most approaches address specific concerns, typically result solutions that aren't able support full-scale data analysis...

Ambient Assisted Living (AAL) systems based on sensor technologies are seen as key enablers to an ageing society. However, most approaches in this space do not provide a truly generic ambient - one that is only capable of assisting people with diverse medical conditions, but can also recognise the habits healthy habitants, well those developing conditions. The recognition Activities Daily (ADL) understanding and provisioning appropriate efficient care. ADL particularly difficult achieve...

Green communication is one of the key goals beyond 5G networks. However, as more and delay sensitive applications emerge, contradiction between task requirement energy conservation becomes prominent on device side. This paper focuses a mobile edge computing system where local capability are both limited, which may lead to discarding due violation. An consumption minimization problem first formulated under binary offloading partial modes. Then low-complexity heuristic scheme Lagrange dual...

This paper mainly introduces the search engine optimization scheme used by airlines to check flight and fare information. The legacy shopping based on IBE has two drawbacks. First, query efficiency is low. Second, ability withstand pressure weak.In order solve these problems, application of cloud computing technology, this proposes a data cache accuracy build new architecture.We will focus how improve accuracy.The shows that been improved from initial 75.62% maximum 98.68%. One airline...
