In this paper, the potential to reduce energy consumption of end devices operating in a LoRaWAN (long-range wide-area network) is studied. An increasing number IoT components communicating over wireless networks are powered by external sources. Designers communication systems concerned with extending time IoT, hence need look for effective methods power consumption. This article proposes two al...

Abstract Mesokurtic projections are linear with null fourth cumulants. They might be useful data pre-processing tools when nonnormality, as measured by the cumulants, is either an opportunity or a challenge. Nonnull cumulants opportunities extreme kurtosis used to identify interesting nonnormal features, for example clusters and outliers. Unfortunately, this approach suffers from curse of dimen...

This article reviews recent advances in missing data research using graphical models to represent multivariate dependencies. We first examine the limitations of traditional frameworks from three di...

Device-free context awareness is important to many applications. There are two broadly used approaches for device-free awareness, i.e., video-based and radio-based. Video-based can deliver good performance, but privacy a serious concern. Radio-based applications have drawn researchers' attention instead, because it does not violate radio signal penetrate obstacles. The existing works design exp...

introduction: it seems that demographic and clinical features of patients referred for myocardial perfusion scintigraphy (mps) is different among populations and healthcare settings. the purpose of the current study is to evaluate the clinical features and risk factors of patients referred for myocardial perfusion scintigraphy to a military hospital. methods: as a cross-sectional study, the cli...

The rapid growing of information technology (IT) motivates and makes competitive advantages in health care industry. Nowadays, many hospitals try to build a successful customer relationship management (CRM) to recognize target and potential patients, increase patient loyalty and satisfaction and finally maximize their profitability. Many hospitals have large data warehouses containing customer ...
