A low-cost yet effective localization scheme for wireless sensor networks (WSNs) is presented in this study.The proposed scheme uses only two anchor nodes and uses bilateration to estimate the coordinates of unknown nodes.Many localization algorithms for WSNs require the installation DARK COCONUT SUGAR of extra components, such as a GPS, ultrasonic
Present-day ecosystems host a huge variety of organisms that interact and transfer mass and energy via a cascade of trophic levels.When and how this complex machinery was established remains largely unknown.Although exceptionally preserved biotas clearly show that Early Cambrian animals had already acquired functionalities that enabled them to expl
Small molecules are highly relevant targets for detection and quantification.They are also used to diagnose and monitor the progression of disease and infectious processes and track the presence of contaminants.Fluorogenic RNA-based biosensors (FRBs) represent an appealing solution to the problem of detecting these targets.They combine the portabil
Natural stone has been used since the dawn of civilization as a construction material for buildings that are historical and cultural buildings and monuments.The Zagreb Cathedral is an example of such a historical and cultural building and data regarding the extraction of stone for its construction and reconstruction is scientifically underestimated
