Free-space detection plays a pivotal role in autonomous vehicle applications, and its state-of-the-art algorithms are typically based on semantic segmentation of road areas. Recently, hyperspectral images have proven useful supplementary information multi-modal for providing more texture details to the RGB representations, thus performing well tasks. Existing methods assume that all inputs well...

We consider the multi-user detection (MUD) problem in uplink grant-free non-orthogonal multiple access (NOMA), where point has to identify total number and correct identity of active Internet Things (IoT) devices decode their transmitted data. assume that IoT use complex spreading sequences transmit information a random-access manner following burst-sparsity model, some data adjacent time slots...

geothermal energy because of its versatility has extensive applications in power generation, industry, agriculture, treatment of diseases etc: ...this source of energy has received great attention in recent years many countries in the world are benefiting from it. it possesses an eternal heat source and is pollution free. in this article it is tried to demonstrate the importance of georhermal e...

as benzimidazole ring is an important pharmacophore in modern drug discovery and benzimidazoles are very important intermediates in organic reactions, the preparation of benzimidazoles has gained considerable attention in recent years. here, a comparative study on the synthesis of benzimidazoles from aromatic, aliphatic and heterocyclic carboxylic acid, benzonitrile and o-phenylenediamine under...

The reduction of CO2 on copper electrodes has attracted great attentions in the last decades, since it provides a sustainable approach for energy restore. During the CO2 reduction process, the electron transfer to COads is experimentally suggested to be the crucial step. In this work, we examine two possible pathways in CO activation, i.e. to generate COHads and CHOads, respectively, by perform...
