The Distance Vector Hop (DV-HOP) localization algorithm, as a non ranging node localization algorithm, its operation is simple, does not require additional measurement equipment support, with low cost.But wireless sensor network is generally used in three-dimensional complex environment.In response to the low positioning accuracy of this algorithm

Biological membranes mediate several biological processes that are directly associated with their physical properties but sometimes difficult to evaluate.Supported lipid face mask bilayers (SLBs) are model systems widely used to characterize the structure of biological membranes.Cholesterol (Chol) plays an essential role in the modulation of membra

Message Queuing Telemetry Transport (MQTT) is expected to be the de facto messaging IoT standard.Therefore, MQTT must achieve efficient security.Nevertheless, the most significant drawback of the MQTT is its lack of protection mechanisms.Meanwhile, the existing approaches have added processing overhead to the devices and are still vulnerable to var

Editors Ball Chairs HARDY and BRYMAN present qualitative and quantitative analysis methods in the same book.The individual chapters tend to deal with one or the other approach, though, and there may have been some opportunities missed in terms of discussing both together.The chapters are of high quality and present the current state of knowledge in
