Design and optimization of multilevel inverters for renewable energy integration
Authors: Renuka A L  , Guruswamy T.B
Published: January 2025

The increasing global demand for clean energy has driven the rapid integration of renewable energy sources such as photovoltaic (PV) and wind energy into the electrical grid. However, the intermittent and variable nature of these energy sources necessitates the development of highly efficient and reliable power conversion systems to ensure stable and high-quality power delivery. Multilevel inverters (MLIs) have emerged as a promising solution due to their capability to generate near-sinusoidal output voltages with significantly reduced harmonic distortion, lower electromagnetic interference, and minimal switching losses compared to conventional two-level inverters. This paper presents an in-depth study on the design and optimization of MLIs specifically tailored for renewable energy applications, including stand-alone and grid-connected PV systems, wind energy systems, and hybrid renewable setups. Key design considerations are explored, including the selection of suitable topologies such as diode-clamped, flying capacitor, and cascaded H-bridge inverters, each evaluated based on their performance metrics, cost, and scalability. Advanced modulation strategies, such as sinusoidal pulse-width modulation (SPWM), space vector pulse-width modulation (SVPWM), and selective harmonic elimination (SHE), are analyzed for their effectiveness in improving power quality and reducing harmonic distortion. Additionally, the role of voltage balancing techniques, thermal management systems, and wide bandgap (WBG) semiconductors in enhancing efficiency and reliability is discussed. Optimization techniques targeting efficiency improvement, power loss reduction, and enhanced fault tolerance are elaborated, alongside emerging trends in the use of artificial intelligence (AI) and machine learning (ML) for real-time control and predictive maintenance. Challenges in grid synchronization, fault detection, and control complexity are critically assessed, with potential solutions proposed to address these issues. The paper also highlights recent advancements in modular multilevel inverter designs and their applicability in distributed energy systems, energy storage integration, and microgrids. By synthesizing the latest research and technological advancements, this study provides a comprehensive framework for the design, optimization, and deployment of MLIs in renewable energy systems. The insights gained underscore the critical role of MLIs in facilitating the large-scale adoption of renewable energy and achieving global sustainability goals, while paving the way for future innovations in power electronics and renewable energy integration.
Vision-guided automation: A generic approach to web form filling using GPT and computer vision
Authors: Leela Gowtham Yanamaddi  , Balaji Kummari
Published: January 2025

Combining computer vision approaches with GPT (Generative Pre-trained Transformer) models, this research presents a novel approach to automating web-based form filling tasks. A general approach that can adapt to different forms without knowing their structure is made possible by the suggested system, which detects and labels interactive elements on web pages visually. This allows it to transcend the restrictions of hardcoded DOM element interactions. Notable advancements include utilising computer vision to recognise and label form elements and integrating GPT models to read form fields semantically and produce context-appropriate responses (for instance, using resume data). Plus, AI-guided judgements are made using a versatile action system that mimics human-like interactions like typing, clicking, and scrolling. An automated job application form filling case study demonstrates the system's efficacy and highlights its potential for wide-ranging online automation activities.

Authors: Abun Abun  , Nadhira Yahdiyani  , Nyimas Popi Indriani
Published: January 2025

Biotechnology, which utilizes bacteria as probiotics in livestock, especially poultry, has been widely researched. Probiotics are known to be used as an alternative to antibiotics in poultry farming. The type of microorganism used as a probiotic is strongly related to the chemical and physical properties of the digestive environment. Therefore, the microbes used must also be specific microbes that can have a good influence on livestock. The mechanism of action of probiotics is also quite diverse. Probiotics have a role in neutralizing toxins produced by pathogenic bacteria and inhibiting the growth of these pathogenic bacteria by preventing colonization of the small intestine wall. The ability of probiotic microorganisms to secrete toxins that reduce or hinder the development of pathogenic microorganisms in the digestive tract also increases immunity in their hosts. Research mentions Lactobacillus sp, Bacillus sp, Aerococcus viridans, Bifidobacterium dentium, Enterococcus faecium, Lactobacillus casei, and Streptococcus uberis as potential probiotics for poultry. The research method used is meta-analysis. This research method is carried out by summarizing, reviewing, and analyzing data from several pre-existing research results. The results of this article were obtained from animal feed biotechnology, the potential of bacteria as probiotics for poultry, and a comparison of the types of bacteria used as probiotics in poultry.

A Systemic Design-Led Participatory Process to Address Meaningful Impact Pathways for Netzero Cities
Authors: Giorgi Debora , Morea Claudia , Frosini Valentina , Rutigliano Chiara , Collacchioni Sofia
Published: January 2025

This work explores the role of design in supporting public administrations to set up local-based NetZero city strategies. In particular the paper presents the design-led participatory process designed and led by the Service Design Lab team (authors) to support the Municipality of Prato in preparing the baseline for the Climate City Contract. Based on four pillars (energy efficiency, sustainable mobility, circular economy, agriculture and land use, urban forestry), the process aimed at spotting systemic barriers and laying the groundwork to co-design a portfolio of actions aimed at achieving carbon neutrality by the year 2030. The strategy supporting the process was based on two main phases (understanding the system and co-designing a portfolio) connected by an intermediary bridging phase, and another cross-cutting level of inquiry itself consisting of two stages: the front-end (the local-based facilitation process) and the back-end (the systemic interconnectedness process). Lastly we highlight the limitations of the process and the key takeaways of participatory infrastructuring actions, and specifically the benefits for the Municipality in establishing meaningful and context-based impact pathways.

Published: January 2025

This paper presents the results of a research project undertaken by a team of researchers at the Università Iuav di Venezia, which began in January 2021 and ended in January 2023. The project investigated the present-day reality of design studios in the Veneto region, to understand the transformations that have occurred in the ways of thinking and acting tied to the modification of the areas of intervention and the design skills that are expected from the designers.
The profession and relationships with companies and clients on the one hand have changed from familiar and historically-practiced approaches, reflecting transformations in the position and role of the designer, and on the other have undergone a significant expansion in the possibilities of intervention.
The final goal of this study is to offer a reflection on the directions in which the profession is moving, with the aim of informing professionals and design businesses, as well as the educational institutions which are forming the next generations of designers.
Material Resources as a Contextual Complex System
Authors: De Chirico Michele
Published: January 2025

To respond to the ongoing cultural, environmental and economic changes, the contribution investigates how sustainable development always refers to the context. It demonstrates how the multidimensional interpretation of resources might lead to sustainable design actions.

The article presents a research project aimed at an original mapping of the presence and use of material resources in local supply chains, in order to rethink their sustainable use through design interventions. According to the definition of “contextual attributes” as a filter of knowledge related to the technical, expressive and cultural aspects that a material brings with it as a resource of a specific context, the research objective is to develop a tool for designers that can help to outline criteria for the knowledge, valorisation and sustainable use of materials by recognising their attributes.
From Sea to Fashion. Seaweeds as Material for a Sustainable Transition
Authors: Moradei Clizia , Franzo Paolo
Published: January 2025

The essay addresses the reasons why fashion design is manifesting an increasing interest in the marine environment as a context where to identify new sustainable materials for fashion, focusing on the particular case of seaweeds. Through the analysis of some significant international case studies, the recent applications of a variety of biomaterials derived from algae are observed. This phenomenon is interpreted not only as a response to the emergencies of innovation and sustainability in fashion design, but also confirms the framework of a new materialism according to a posthuman perspective. Water shifts from being perceived as a natural element exploited and polluted by fashion into a place of making kin between human and non-human through the use of seaweeds. This is possible thanks to the collaboration of design, chemistry, biology and technology, that are orchestrated to redefine the expressive codes of contemporary fashion within a multispecies landscape.

Authors: Farid Muh , Septyandy Muhammad Rizqy , Heriyanto Heriyanto
Published: January 2025

This research was conducted in Sungai Kunjang District, Samarinda City, East Kalimantan Province. Based on the regional geology of Samarinda, this location is included in the stratigraphy of the Kutai Basin with the Balikpapan and Balang Island Formations. This research focuses on determining the flood hazard areas around the Premiere Hills housing complex. The research method used is weighted overlay using spatial analysis, which overlays several maps related to factors that influence vulnerability assessment. The analytical tool used is the Geographic Information System (GIS). Each parameter is given a weight by scoring each parameter, namely land use, elevation, river buffer, rainfall, soil type, and slope slope. An overlay is carried out to obtain the classes of flood hazards. Then, field verification is carried out to determine whether the areas on the flood hazard map match those in the field, especially in areas with a high level of flood hazard. In the analysis results obtained using the weighted overlay method, the research area has a relatively high level of flood danger, which can be seen on the hazard map, where the colour red dominates compared to areas that have a low or medium level of flood danger, which are marked with green and yellow on the map. Based on the analysis results of areas with high flood hazards, verification is carried out to see whether the areas with high flood hazards follow those in the field. It can be seen from this verification that three points are taken, which are areas where flooding often occurs, characterized by low elevation and have poor drainage channels that prevent water from flowing properly

Gerek uluslararası örf ve âdet gerekse sözleşme hukuku, devletlerin, faili kim olursa olsun, kadınlara yönelik şiddet eylemlerini önlemek, mağdurları korumak, failleri cezalandırmak ve şiddetin yol açtığı zararı tazmin etme yönünde gerekli özeni gösterme yükümlülüğü bulunduğu kuralını kabul etmiştir. Böylece, devlet doktrinin pozitif yükümlülük anlayışını da içermesiyle şiddetle mücadele ivme kazanmıştır. Bu yöndeki önemli gelişmelere rağmen, şiddetin tüm dünyada artma eğiliminde olması uluslararası norm ve pratik arasındaki mesafeyi açmakta ve sorunun ‘objektif’ hukuk normlarının uygulanmasından ibaret olmadığı gerçeğini ifşa etmektedir. Bu çalışma, devletin özen yükümlülüğü standardının, özellikle şiddetin önlenmesi bağlamında uluslararası belge ve mekanizmalarda yorumu, olanakları ve sınırlarına odaklanmakta ve direnen yapısal eşitsizlikler, ekonomi politik dinamikler, toplumsal cinsiyetin anaakımlaştırılması yaklaşımının çelişkileri karşısında, anaakım toplum düzenini dönüştürecek yeni bir feminist vizyonun gerekliliğini savunmaktadır.

Published: January 2025

Jaminan status halal suatu produk sangat penting bagi konsumen Muslim, terutama di Indonesia, negara dengan mayoritas penduduk Muslim terbesar di dunia. Pemerintah, melalui Kementerian Agama, telah menerapkan sertifikasi halal untuk menjamin validitas produk. Namun, penerapan sistem jaminan halal tetap kontroversial, dengan sebagian melihatnya sebagai upaya untuk keuntungan pemerintah, terutama Kementerian Agama melalui MUI (Majelis Ulama Indonesia). Sentimen negatif dari kelompok yang berlawanan dapat berpotensi eskalatif dan memengaruhi individu atau komunitas lain jika tidak ditangani dengan tepat. Salah satu langkah preventif adalah mempromosikan edukasi dan kesadaran produk halal melalui media digital, khususnya media sosial. Mengingat penggunaan media sosial yang luas, terutama di kalangan milenial, media sosial dapat menjadi platform yang efektif dan hemat biaya untuk edukasi dan promosi. Upaya edukasi melalui media sosial memerlukan strategi khusus untuk memastikan diseminasi informasi yang optimal sesuai harapan. Memahami pola dan karakteristik konten serta konteks sosio-kultural pengguna media sosial sangat penting. Pemahaman ini dapat dicapai melalui analisis komprehensif terhadap beragam dan melimpahnya konten yang dihasilkan pengguna di platform media sosial. Oleh karena itu, penelitian ini mengusulkan metode berbasis text mining untuk mengembangkan kerangka kerja dalam memahami karakteristik dan dinamika percakapan publik mengenai produk halal di media sosial.

Renewables in Countries of North Africa: Problems and Prospects of Use
Authors: Shkvarya Ludmila
Published: January 2025

The article examines the approach of the North African countries to the development of renewable energy sources (RES). It is shown that there are a number of factors that reinforce the need for the development of renewable energy in the region, including the unstable macroeconomic situation, population growth and urbanization, climate change, the EU policy on geographical diversification of energy suppliers, and the EU’s reorientation to alternative energy sources. At the same time, energy transfer carries significant risks both for the functioning of energy systems and for the economy. The development of green energy requires large investments, often inaccessible to African countries, and access to technology; at the same time, the inclusion of renewable energy in energy systems makes the latter less stable due to the emergence of dependence on weather changes. In addition, the countries of North Africa have their own hydrocarbon resources, and the refusal to use them is simply illogical. When it comes to costs, green energy is more expensive than traditional energy. In this regard, unconditional adherence to the EU’s energy policy and climate agenda cannot be considered an optimal scenario for the countries of the region. The study showed that the countries of North Africa, having announced overly ambitious goals for the development of renewable energy, faced the inability to implement plans. In this regard, the task of developing green energy should not be more significant than the task of maintaining the functioning of the energy industry as a whole, and renewable energy sources should not replace but only complement traditional energy.
Difference of Approaches to the Concept of Equality: Western Tradition and L.S. Senghor
Authors: Ponomarev Ilya , Tutorsky Andrey
Published: January 2025

In this paper, the authors present a comparative perspective of the notion of equality in the Western school of scientific thought—a notion that became the cornerstone for specific scientific concepts in Western social and political philosophy—and the non-Western approaches to equality, taking as an example of the latter the ideas of the Senegal politician and philosopher L.S. Senghor. Such a comparison is of interest because the African thinker, although he had studied in France and enjoyed political recognition there, understood the concept of equality in postcolonial context quite differently from the Western philosophers. Other African postcolonial political figures (e.g., J. Nyerere) have also addressed the equality concept, but it is Senghor’s ideas that demonstrate so openly the African alternative to the Western approach. Senghor’s concept of equality is inseparable from his postcolonial political activities: during this period of his life, he introduced a notion of Civilisation de l’Universel, Civilization of the Universal, which was based on this concept. According to Senghor, such a civilization should evolve through the use of dialogue on equal terms, integrating the values of different civilizations of the West and East. He juxtaposed this notion with the one of civilisation universelle, Universal Civilization, the evolution of which is based exclusively on Euro-American values and can, in its technocrat rush, distort human nature, leading to the demise of humankind. Trying to resolve the dichotomies of Eurocentric approach, born of the gap between rational and intuitive thinking, Senghor adopts a concept of equality as unity, which brings him close to the Eastern Christian tradition of interpreting equality. It is in sharp contrast to Euro-American social tradition, which focuses solely on rational and ideological conceptualizing.
Protocols for maintaining a colony of Manduca sexta (tobacco hornworm) suitable for studies of innate immunity and other investigations of a model insect species

Manduca sexta, the tobacco hornworm, is a lepidopteran species often used as a model organism for biological research. It reaches a large size (~10 g) as a last instar larva, useful for biochemical studies, and its development can be synchronized for studies of endocrinology and developmental regulation. We describe here our detailed protocols for rearing a continuous colony of M. sexta in the laboratory. We feed larvae an artificial diet based on wheat germ and rear larvae at 26°C in individual plastic cups with clean procedures to produce larvae suitable for studies of immune responses. Wandering larvae at the end of larval development are placed in plastic boxes containing vermiculite for pupation, and then pupae are transferred to clean plastic boxes in the incubator. Prior to adult emergence, pupae are placed in a cage with a tobacco plant. Moths mate and oviposit on the leaves, and eggs are collected for continuation of the colony.
Changes in Glenohumeral Musculoskeletal Development Following Brachial Plexus Birth Injury
Authors: Cole Jacqueline , Fawcett Emily , Bosh Kyla , Saul Katherine
Published: January 2025

Brachial plexus birth injury (BPBI), one of the most common nerve injuries in children, often leads to impaired shoulder development, resulting in sustained postural and bone deformity and muscle weakness. Despite the substantial long-term consequences, clinical consensus is lacking for what BPBI treatments are optimal in terms of timing and approach, primarily because BPBI sequelae are complex, involving stunted muscle growth, muscle denervation, and limb disuse that can disrupt glenohumeral joint development. Injury can occur as nerve rupture (postganglionic injury) or nerve avulsion (preganglionic injury), which have distinct musculoskeletal consequences yet are often treated similarly clinically due to their similar initial presentations and the inability of existing methods to distinguish between them. Most of our clinical knowledge about the musculoskeletal detriments in the shoulder comes from studies in nerve rupture patients. Knowledge is generally lacking for the specific effects of injury location on the development and progression of muscle and bone deficits following BPBI. A better understanding of the distinct effects of postganglionic and preganglionic BPBI is important for developing more effective and targeted treatments. More studies are needed to elucidate differences between nerve rupture and nerve avulsion and the particular factors driving glenohumeral deformity development. This paper reviews current knowledge about clinical musculoskeletal deformity development in the shoulder following BPBI, as well as additional insights gleaned from animal and computational models, and identifies key gaps that need to be addressed in future studies to inform better approaches for mitigating and preventing glenohumeral deformity in these patients.
