Electric mobility and particularly electric cars are seeing a comeback. Several mass manufactured models have even already seen updates. Established and newcomer car manufacturers are scrambling to bring new models to market and considerable research resources are invested to solve the problems. This paper looks at the current challenges and probable future trends regarding the cars, their batteries and the charging infrastructure. Global, European and regional conditions for electric car adoption are also discussed.

Humanoid robots are increasingly being utilized in various activities involving humans, as they can facilitate certain tasks and provide benefits to users. Humanoid service robots possess capabilities akin to human performance, often proving advantageous due to their operational speed and immunity to fatigue. Within the scope of this study, Pepper, a humanoid robot renowned for its fidelity in mimicking human gestures and behavior, serves as the focal point. Tasked with aiding office occupants in object manipulation and relocation, Pepper underwent a targeted reliability assessment. This assessment encompassed the development of a reliability block diagram (RBD), alongside meticulous analyses of individual components and system functionality across diverse operational scenarios.

Robots can be very different, from humanoids to intelligent self-driving cars or just IoT systems that collect and process local sensors’ information. This paper presents a way to increase dependability for information exchange and processing in systems with Cloud-Fog-Edge architectures. In an ideal interconnected world, the recognized and registered robots must be able to communicate with each other if they are close enough, or through the Fog access points without overloading the Cloud. In essence, the presented work addresses the Edge area and how the devices can communicate in a safe and secure environment using cryptographic methods for structured systems. The presented work emphasizes the importance of security in a system’s dependability and offers a communication mechanism for several robots without overburdening the Cloud. This solution is ideal to be used where various monitoring and control aspects demand extra degrees of safety. The extra private keys employed by this procedure further enhance algorithm complexity, limiting the probability that the method may be broken by brute force or systemic attacks.

This paper proposes an electronic vote scheme generated by the ring signature with divised private key. The algorithm respects the basic requirements regarding the voting process. The fact that it comes from a ring signature confers a strong anonymity to the developed scheme. The mathematical structure where the work in done is the remainder classes modulo n ring. There are presented two variants, the first one refers to the situation when all voting entities are registered before the voting process and the second one offers the possibility to vote other entities, entities who weren't registered before, too. The security from the cryptographic view is also analized.
