Operational safety and health monitoring are critical matters for autonomous field mobile robots such as planetary rovers operating on challenging terrain. This paper describes relevant rover safety and health issues and presents an approach to maintaining vehicle safety in a navigational context. The proposed rover safety module is composed of two distinct components: safe attitude (pitch and ...

The use of biomaterials to restore the function of traumatized or degenerated connective tissues and thus improve the quality of life of a patient has become widespread. In the past, implants were designed with insufficient cognizance of biomechanics. Accordingly, the clinical results were not very encouraging. An upsurge of research activities into the mechanics of joints and biomaterials has ...

This paper seeks to shed light on certain major aspects of public policy and the performance of business enterprises in India. First, it highlights the effectiveness of the public policies pursued and their asymmetric effects on corporate governance and performance of multinational and local enterprises in India. Second, it suggests that the so called ‘threat’ of large scale disruption of local...

Taking cognizance of the United Nations Sustainable Development Goal 7 “affordable and clean energy”, metal–organic frameworks (MOFs) derived materials have spurred research interest in electrocatalysis. New findings made headway water splitting (oxygen evolution reaction hydrogen reaction) other electrocatalysis, including oxygen reduction electrochemical CO2 reduction. Thanks to their structu...

Ionic liquid based electrolytes are gaining great interest in the field of photoenergy conversion. We have found that the ionic liquids namely BMIm Cl, BMIm PF6 and BMIm Tf2N inherently offer redox activity. The device performance of the photoelectrochemical (PEC) cells of the configuration PbOx (0.25 cm(2))|blank ionic liquids|platinum (2 cm(2)) was analyzed in detail to get insights into the ...

With the continuous development of huge systems, dependence on the system is continually increasing. The failure of such systems will cause huge losses. The reason for system failure is often unclear, so that inconsistency and uncertainty between fault data will appear. In the actual application process, there is a process of change. If it is possible to predict the failure probability from the...

map is the most important tool for cognizance in the field of geography and is the best instrument for presentation of geographic information. the study of ecology in general, which means the study of relationship between man and his environment, is only possible by means of maps. as a tool for ecology and manifestation of human sovereignty over environment, the map has served political power-h...

The role of conventional graphene-oxide in biosensing has been limited to that of a quenching substrate or signal transducer due to size inconsistencies and poor supramolecular response. We overcame these issues by using nanoscale GOs (nGO) as artificial receptors. Unlike conventional GO, nGOs are sheets with near uniform lateral dimension of 20 nm. Due to its nanoscale architecture, its supram...
