Internet of Things (IOT) offers a new dimension technology and information where connectivity is available anywhere, anytime, for any purpose. IEEE 802.11 Wireless Local Area Network group standard that developed to answer the needs wireless communication (WI-Fi). Recently, working released 802.11ah or Wi-Fi HaLow as Wi-fi standard. This works on 1 GHz frequency band with broader coverage area,...

We consider a mobile ad hoc network consisting of three types of nodes: source, destination, and relay nodes. All the nodes are moving over a bounded region with possibly different mobility patterns. We introduce and study the notion of relay throughput, i.e. the maximum rate at which a node can relay data from the source to the destination. Our findings include the results that a) the relay th...

Since the reform and opening up, the Chinese economy has achieved sustained high-speed growth. However, the widening gaps in income, especially for rural China, seem to be a dark lining to these extraordinary achievements. Taking the duration of poverty into the consideration, this article analyzes the income inequality of rural per capita net income (RPCNI) based on income mobility in rural Ch...

Meanwhile, one of the key factors influencing the quality of life of older people is their mobility. Most of the previous studies have considered the mobility of younger people while considering the aging of the population, the mobility of older people n...

BACKGROUND Over the last few years, differential ion mobility spectroscopy (DMS) has become an important tool in medical research. There are attempts to find markers for specific diseases in exhaled air, using this technology as a non-invasive early diagnosis. OBJECTIVE In the present research, exhaled air from 78 patients with known diagnosis and 39 control persons were tested with a DMS sys...
