Disturbance Rejection-Based Optimal PID Controllers for New 6ISO AVR Systems

In the literature, different approaches that are employed in designing automatic voltage regulators (AVRs) usually model the AVR as a single-input-single-output system, where the input is the generator reference voltage, and the output is the generator voltage. Alternately, it could be thought of as a double-input, single-output system, with the excitation voltage change serving as the additional input. In this paper, unlike in the existing literature, we designed the AVR system as a sextuple-input...

Decompression procedure as a successful initial approach to large maxillary dentigerous cyst in 12- year-old boy - a case report

Introduction. A dentigerous cyst is a pathological lesion associated with the crown of the unerupted or impacted tooth. Decompression is proposed as the initial treatment for large cysts, especially in younger patients. The aim of this study was to present clinical, radiological, histopathological, and therapeutical aspects of the large dentigerous cyst in the maxilla. Case report. A 12-year-old boy with a large dentigerous cyst in the maxilla was referred to our clinic. A dentigerous cyst was associated...

SNP Diversity and Genetic Structure of “Rogosija”, an Old Western Balkan Durum Wheat Collection

Durum wheat landraces represent a genetic resource for the identification and isolation of new valuable genes and alleles, useful to increase the crop adaptability to climate change. Several durum wheat landraces, all denominated “Rogosija”, were extensively cultivated in the Western Balkan Peninsula until the first half of the 20th century. Within the conservation program of the Montenegro Plant Gene Bank, these landraces were collected, but without being characterized. The main goal of this study...

Influence of temperature and plastic deformation on AA2024 T3 friction stir welded joint microstructure

This paper deals with analysis and comparison of the equivalent plastic strain and temperature fields in the aluminium alloy 2024 T3 (AA2024 T3) joint, with macro/microstructure appearance and hardness profile. In the alloys hardened by heat treatment, grain size and particle size of the precipitate are functions of equivalent plastic strain, strain rate and temperature. By analysing the equivalent plastic strain fields and temperature fields it is possible, to some extent, to capture the effect...

Self-Heating Flower-like Nanoconstructs with Limited Incorporation of Yttrium in Maghemite: Effect of Chemical Composition on Heating Efficiency, Cytotoxicity and Genotoxicity

Partial cation substitution can significantly change the physical properties of parent compounds. By controlling the chemical composition and knowing the mutual relationship between composition and physical properties, it is possible to tailor the properties of materials to those that are superior for desired technological application. Using the polyol synthesis procedure, a series of yttrium-substituted iron oxide nanoconstructs, γ-Fe2−xYxO3 (YIONs), was prepared. It was found that Y3+ could substitute...

Do Statistics Show Differences between Distance Estimations of 3D Objects in the Traffic Environment Using Glances, Side View Mirrors, and Camera Display?

The driver’s task in traffic is to evaluate traffic situations and act in accordance with the estimate. One of the most common causes of road crashes is “incorrect estimated of the traffic situation”. Correct perception of surroundings is one of the prerequisites for safe and successful driving. To investigate the mentioned issue, the authors of this paper conducted an experimental study with the aim of determining what affects the estimation of the object distance. In contrast to previous studies...

Applications of Energy Storage Systems in Enhancing Energy Management and Access in Microgrids: A Review

As the world’s population continues to grow and the demand for energy increases, there is an urgent need for sustainable and efficient energy systems. Renewable energy sources, such as wind and solar power, have the potential to play a significant role in meeting this demand, but their intermittency can make integration into existing energy systems a challenge. Moreover, the development of sustainable energy systems has become even more critical in recent years, due to a confluence of events, including...

REHABILITATION AFTER AN ATHLETE'S ANKLE INJURY

Introduction: A bone fracture is a break in the continuity of bone tissue, caused by the action of an external or internal force on the bone. Ankle sprains are one of the most common injuries among athletes. Physically active people who participate in activities that require jumping, changing direction, and turning have an increased risk of ankle sprains. Ankle sprains and the repetitive trauma often associated with this condition can lead to long-term disability, lost time from activity, and financial...

MCDM MODEL FOR CRITICAL SELECTION OF BUILDING AND INSULATION MATERIALS FOR OPTIMISING ENERGY USAGE AND ENVIRONMENTAL EFFECT IN PRODUCTION FOCUS

In the context of sustainable buildings, an ecological study of building and insulating materials is critical since it may assist affirm or shift the path of new technology development. Utilising sustainable material is a part of the sustainable improvement. For this reason, material fabrication is the primary process for the energy usage and release of intense environmental gaseous. The fabrication of the insulation and building materials, as in every fabrication process, comprises an energy consumption...
