Internet of Things (IoT) enabled applications to become an outstanding part of the everyday activities across all industries. IoT systems are prone to cybersecurity incidents due to lack of human observation on the system. Machine Learning (ML) offer robust solutions that can implement security mechanisms for IoT systems. The current paper proposes an implementation of a device identification system based on ML algorithms, a comparison between some ML algorithms and a comparison between three different hardware platforms that can be used to implement the device identification mechanism.

The paper presents the electromagnetic torque dependence with the rotor’s speed of a five phase induction motor using the Finite Element Analysis. In this study, both frequency domain analysis and step by step in time domain analysis are made imposing the rotor’s speed. It is proposed an operation point for continuous operation under one open-phase fault.

In order to study the behavior of photovoltaic (PV) panels, controlled simulation of lighting conditions is a must. For the comparative analysis of the maximum power point tracking algorithms, these lighting conditions must be reproduced identically for each individual algorithm. This article proposes such a controlled lighting system that can be easily integrated into a more complex system for the study of PV panels. Due to size and energy consumption considerations, the solar simulator is sized for 20W photovoltaic panels, but it can be easily expanded for PV panels of higher power. The lighting control can be done manually or automatically, and the simulator operation can be independent or synchronized with other experimental measurement modules. In case of automatic operation, the simulator allows establishing and memorizing a lighting profile that can be played later individually or periodically. The simulator can generate step or ramp lighting variations that can be combined within the lighting profile for programmable time duration for each interval.

Over the last years, solar energy has become of great interest regarding new solutions of energy harvesting, especially when it comes to the global warming topic. Hence, photovoltaic cells have gained a lot of popularity and have grabbed the attention of multiple industries that are looking to expand their energy harvesting applications, whether it means powering up certain systems or storing the energy for later usage. This paper describes a possibility of maximizing the solar energy harvesting capability of a photovoltaic system, employing light sensors for maximum power point tracking, and adjusting the position of the photovoltaic panels. Even though the efficiency of this technology is able to sustain the power consumption on a large scale, improvement methods are always researched.

The paper analyses the integrated management system of a marine vessel and the role of the gyrocompass within the governance system. The Energy Management System is presented with the three related subsystems: SafeSeaNet, RIS and ITS. The development of the CSCES, the implementation of the IBC and of the CBM system, the introduction of the PEBB, the supervision of the integrated navigation system with a SCADA system, constitute the basis of the hereby carried out study. Starting from the block diagram of the integrated navigation system, the block diagram for controlling the navigation information was created and depending on the errors given by the gyrocompass, an interface was created that intervenes in the process of digital/analog representation of the signals based on the electrical model of the gyrocompass.

Even though working with unlabeled data has the main advantages of lower preprocessing time and resources, the drawback is that the algorithms implemented have no connection between the output and ground truth, therefore is extremely hard to represent the results. This paper proposes a deployable stand-alone module for extracting the real color of the identified classes for a more intuitive representation of the final results.

Saint Martin’s Island of Bangladesh, located remotely in the Bay of Bengal, is isolated from the national grid system. Due to its geographical location, solar power is available throughout the year in the island. Consequently, solar photovoltaic (PV) technology is currently being used for generation of electricity while battery energy storage system (BESS) is being used as a power backup. However, the BESS involves high installation and operational costs, and its lifespan is also relatively short. One way to address this issue is to utilize the thermal energy storage (TES) of concentrated solar power (CSP) technology along with concentrated solar photovoltaic (CPV) system. In this context, the feasibility of a hybrid CSP-CPV based power plant assisted by linear Fresnel reflector technology is investigated in this paper. A novel dataset of load demand is collected from the consumer end by conducting a survey. Moreover, the matching of generation with the instantaneous load demand is assessed by changing the direction of the linear Fresnel reflector mirrors. Different combinations of CPV, CSP and BESS are investigated in the study by varying their ratio. The findings show that the installation cost reduces as more of the BESS is replaced by the CSP technology. The cost is found to be minimum for the combination of 31.5% CPV and 68.5% CSP. Furthermore, the cost-effective appropriate combination also satisfies the load demand in every possible scenario. As such, with the free rotation of the reflector faces, the CSP-CPV based hybrid power plant can offer cheaper electricity to the consumers while ensuring sensitivity to load variability.

In this paper the gm/ID methodology for designing analog CMOS circuits is used. As a case of study the single-ended Miller OTA design is widely discussed and analized. In order to show the advantage of gm/ID it is demonstrated that the first order building block approximation allows to understand not only how to correctly do the sizing of each transistor, but also the physical meaning of each small-signal design model. This design flow is carried out by using design rules of a 130 nm CMOS technology, where Cadence is used for performing simulations at transistor level, obtaining results that confirm the usefullnes of the design models and the basics’ veracity.
