There are many demands for the cooperative localization (CL) of multiple people, such as firefighter rescue. The classical foot-mounted inertial navigation based on zero velocity update (ZUPT) suffers from accumulating error due to low-cost sensor, and pre-placed anchors in ultra-wideband (UWB) system limit application an unknown environment. In this study, a group sensors including measurement...

Space exploration has witnessed revolutionary changes upon landing of the Perseverance Rover on Martian surface and demonstrating first flight beyond Earth by Mars helicopter, Ingenuity. During their mission Mars, Ingenuity collaboratively explore surface, where scouts terrain information for rover’s safe traversability. Hence, determining relative poses between both platforms is paramount impo...

Nowadays, wireless sensor networks are often deployed on the sea surface for ocean scientific monitoring. One of the important challenges is to localize the nodes' positions. Existing localization schemes can be roughly divided into two types: range-based and range-free. The range-based localization approaches heavily depend on extra hardware capabilities, while range-free ones often suffer fro...

To improve the localization precision of nodes in Wireless sensor network (WSN), this paper analyses the source of the localization error in the least square localization algorithm (LSL), and it can be concluded that the minimum cumulative relative distance error of the benchmark anchor node directly influence the localization precision. Based on the analyses, this paper proposes an improved le...

even though some scholars do not agree on the direct link between globalization and translation, most others believe that the process of globalization has influenced translation practices over time. the present research, thus, endeavors to probe into the nature of these impacts and shed some light on the manifestations of globalization trend in the translations of literary texts. to this aim, t...

background: the canonical wnt signal transduction (or the wnt/β-catenin pathway) plays a crucial role in the development of animals and in carcinogenesis. beta-catenin is the central component of this signaling pathway. the activation of wnt/β-catenin signaling results in the cytoplasmic and nuclear accumulation of β-catenin. in the nucleus, β-catenin interacts with the tcf/lef transcription fa...

Many localization algorithm proposed for wireless sensor networks(WSN) . Localization is a term that can be defined as the determination of the exact physical location of each sensor node in a geographic map or to find its relative location from a topology map in a given network structure. Many localization algorithms for MWSN are less accurate and more time consuming. Localization In this pape...
