Memory Utilization

Sharing, transmitting, and storing data has been one of the great needs of today. In the last years, concepts and developed methodologies of cloud computing systems have been improved. This concept created in the 1960s today is present in daily life from ordinary users to even large companies. The present study aims to develop a method of data transmission based on discrete event concepts. This methodology was named CBEDE (by the acronym). The experiments were matched in the MATLAB software simulation environment, where the memory consumption of the proposed methodology was evaluated. Therefore, the CBEDE methodology presents great potential to intermediate users and computer systems, ensuring speed, low memory consumption, and reliability. Being the differential of this research, the use of discrete events applied in the physical layer of a transmission medium, the bit itself, being this to low-level of abstraction, the results show better computational performance related to memory utilization related to the compression of the information, showing an improvement reaching up to 69.93%

To anticipate threats, the Intrusion Detection System (IDS) enables the collection and use of information from various types of attacks to defend an entire network infrastructure. Therefore, this chapter develops a method of data transmission based on discrete event concepts, due to the fact that in this digitally globalized world, networks deal with a huge set of data all the time. Data refers to facts, events, actions, activities, and transactions which have been and can be recorded, i.e., the raw material from which information is produced, nurturing the infrastructure and components that enable modern computing. This methodology was named CBEDE and experiments were matched in the MATLAB software, where the memory consumption was evaluated, presenting great potential to intermediate users and computer systems. Results showed better computational performance related to memory utilization related to the compression of the information, showing an improvement reaching up to 114.39%.

Risk Rate

The aim of risk management of socio-cyber-physical systems at operation is the integral safety which ensures their co-existence with their vicinity throughout their life cycles. On the basis of present knowledge and experience, part of risks that threaten socio-cyber-physical systems is coped by preven-tive measures during their designing and manufacturing. Due to dynamic changes of the world, the con-ditions of socio-cyber-physical systems at operations change. If changes exceed the socio-cyber-physical systems´ safety limits which were inserted into their designs, the accidents or socio-cyber-physical systems´ failures occur. The paper contains the Decision Support System for determination of risk rate of socio-cyber-physical systems. Its regular application shows present-day risk rate and allows to reveal danger situations and in time to apply mitigation measures. The methodology can find several applications in Education, especially in Engineering Education.

The present study aims to implement a discrete event simulation (DES)-based model. This model is called coding of bits for entities by means of discrete events (CBEDE) and aims to improve the transmission of content in wireless telecommunication systems. This is done by applying advanced modulation format DQPSK in a simulation environment, the Simulink of the MATLAB software, through a pre-coding process of bits applying discrete events in the signal before of the modulation process, occurring in the discrete domain with the implementation of discrete entities in the process of bit generation applied at a low level of abstraction in a wireless telecommunication system. The results show improvements of 89.08% in memory utilization, related to information compression, in the context of the research. Therefore, the presented results of the proposed methodology show an enormous potential for the non-orthogonal multiple access (NOMA) contexts, credited as the future 5G, and can compensate for the additional complexity brought by the techniques to the telecommunications channel.
