Due to the sustainable properties, technological innovation in electric batteries, as well as the low pollution, using electric vehicles (EVs) for transportation systems has attracted considerable attention. However, the spread of EVs and increased reliance on them instead of fuel cars are mainly depends on strategic placement of EV charging stations (CSs). Optimal placement of EVCS problem has been investigated from different points of view in the literature. This review study focuses on viewing some of recent approaches that have been proposed in the literature from two different perspective

Micro, small and medium-sized companies represent the main engine of economic development in the world since they constitute 90% of established companies, contributing 50% of GDP and 70% of formal employment; In Peru there are similar figures since SMEs constitute 95% of formal companies and provide more than 85% of formal employment. There are various productive sectors in Peru, among which the textile and clothing sector stands out, which contributes 7.2% of the gross domestic product (GDP), concentrates approximately 700,000 workers and has been energized by some trends such as nearshoring.

For performing information exchange Internet of Things has become a new advancement in communication technology. IoT services become more accessible with the increase in the number of sensor devices or smart devices being in use. These devices play a major role in our lives, whether in our homes, offices, agriculture, healthcare, or other fields. Ensuring the security and privacy of data, devices, as well as underlying infrastructure, is one of the major concerns, these days. Therefore, it requires authentication of devices and session key establishment. Mutual authentication of these devices

The Internet of Everything (IoE) is proving to be highly beneficial in the health monitoring of COVID-19 patients during the global epidemic. This research proposes an IoE-based system that predicts health monitoring by analyzing crucial metrics for intensive care, including body temperature, oxygen saturation, and heart rate. The system features a liquid crystal display (LCD) that shows the monitored temperature, heart rate, and blood oxygen levels, and can be easily integrated with a phone website for immediate access. The suggested IoE-based method was tested and validated on four sensory t

Recently Yang-Roh-Jun introduced the notion of ordered BCI-algebras as a generalization of BCI-algebras. They also introduced the notions of homomorphisms and kernels of ordered BCI-algebras and investigated related properties. Here we extend their investigation to ordered homomorphisms, i.e., order-preserving homomorphisms. To this end, the notions of ordered homomorphism and kernel of ordered BCI-algebras are first defined. Next, properties associated with (ordered) subalgebras, (ordered) filters and direct products of ordered BCI-algebras are addressed.
