‘Clifford Algebra’ Complex Numbers For 3-D Vector Representation
type: item
description: The use of quaternions has historically been an approach to extend complex numbers to represent 3-D vectors. This quaternion representation is not unique. It is shown that an alternative approach to such an extension is to define complex numbers obeying a Clifford algebra different from those of quaternions. Such an algebra is not new but appears to be preferable and less likely to cause confusion.

Future-Proofing Coastal Cities Against Sea Level Rise: Adaptation Strategies
type: item
description: This paper examines comprehensive adaptation strategies for American coastal cities facing accelerating sea level rise (SLR) in the 21st century, with specific focus on five vulnerable urban centers: Miami, Florida; Norfolk, Virginia; Charleston, South Carolina; New Orleans, Louisiana; and Houston, Texas. Current projections indicate 10-12 inches (25-30 cm) of sea level rise along U.S. coastlines by 2050, with potential for significantly higher levels by 2100 depending on global emissions trajectories. The paper evaluates integrated approaches combining engineered defenses, nature-based solutions, policy frameworks, and managed retreat options tailored to the unique geographic, economic, and social characteristics of each city. Multiple case studies demonstrate that successful adaptation requires multi-stakeholder collaboration, substantial investment, innovative financing mechanisms, and strategic long-term planning. The research concludes that while technical solutions exist to protect critical infrastructure and communities in the near term, their viability diminishes as sea levels continue to rise, necessitating transformative approaches to coastal urban development and management for true long-term resilience.

Conservation of Energy and Momentum of Drifting Electrons in Materials
type: item
description: In this research article, conservation of energy and momentum of drifting electrons in materials is expressed in a differential equation form. The equation is derived starting with Einstein’s mass-energy equivalence relation of 1905 for relativistic masses. The equation is valid for both small and large objects. Conservation of momentum is added to the equation and it is shown that Noether’s theorem is asserted. The drift velocity in metals is drastically reduced due to the much higher electron effective mass in metals.

Ecological Contribution to the Replacement of Artificial Coral Reef Settlements Using Concrete Structures made with Hybrid Cements
type: item
description: Studies indicate that artificial reefs for coral reef restoration are often based on concrete structures, and the insertion of these structures is lately produced with hybrid cements that add common Portland cement and other new slag-based cements, as complementary elements in the set of essential raw materials for the study, production and installation of artificial marine reefs, contributing in a stable way to the development of its fauna and flora in a safe and sustainable way, given the use of in situ monitoring processes that combine the obtaining of results from the experiments, regarding their physical and mechanical characteristics in situ. The application of concrete in reef restoration has several benefits, among which are durability, stability, safety, availability and flexibility of the shape and its chemical composition like the reef substrate. Constant global variations in coral protection have led to a call for global climate action, for better management of critical places such as overfishing and pollution, as well as an increase in efforts aimed at recovery. The reconstruction of coral reefs has been carried out on smaller scales and experimental actions, leaving ample field for new options. The underwater environment of coral islands contains concrete structures of different designs and geographical origins, characterized by an open pattern, deposited as cages on mats based on the seabed, creating a zone of biological equilibrium. The use of these large rigid structures allows the marine environment to be protected from illegal trawling movements, contributing to the recovery of biological diversity in areas of compatible depths, without the force of extreme currents as well as the absence of extreme climatic conditions, to ensure the durability of the structures. In a different way, in coral maintenance is applied, where corals are first grown in nurseries and then planted on recovered or artificial reefs, given that artificial reefs have differen…

The Effect of Soybeans Hull (Glycine Max), Beans Pod (Phaseolus Vulgaris) and Dry Willow Leaf (Salix Spp) on the Properties of aSimple Water -Based Mud
type: item
description: This study is aimed at investigating the effects of varying concentration temperature and aging time on the property of a water-based mud treated with agrowaste materials, (soybean hull, beans pod and dry willow leaf with CMC used as control. From the result, it was observed that the mud samples containing soybeans have the highest plastic viscosity with those with dry willow leaf the highest yield point. The effect of aging on the mud sample shows the plastic viscosity of each of the mud sample decreased with soybeans having the highest plastic viscosity. While the yield point and gel strength at 10 minutes and 10 seconds increased respectively with dry willow leaf having the highest yield point. The result of the fluid loss shows the mud samples treated with dry willow exhibiting the closet linear relationship with sample treated with CMC at room temperature, but as temperature increased samples with beans pod exhibited the closet linear relationship with that of the control.

Topology of Emergent Time
type: item
description: We delve into the topology and morphology of the emergent time that arises from a electrons kinetic cloud virtually confined in a toroidal shape due to high-opacity environments. Different results using the most usual opacity models are shown. We analyze the dynamics that best represent such complexity, especially for stellar environments, focusing on the inner, mid and outer zones of the radiative layer. Detailed results of the expected induced Gravity, including their values and the time needed to be conserved over cosmological Time are shown. Then we extrapolate the results of the Gravity induced by the emergent time for different types of stars in function of their percentage per size and by mass, infering that the 95% of the Gravity created in the stars ranges from -43% till 19% of the emergent gravity arised in Sun-like stars. Finally we show how the variabilty of the gravitational constant could be demonstrated by experiments carried out on the Earth itself and how a new discipline “PaleoGravity” based on them could help us to study the origin of any chemical element present on Earth, the solar system and even asteroids.

Oracle's Multi-Cloud Interoperability
type: item
description: Cloud adoption is now more of a multi-vendor solution rather than a single vendor solution, and multicloud solutions, whereby organizations have taken the services of more than one vendor to gain flexibility, resiliency, and performance. Oracle has now established a foothold in this spot with interoperability between the Oracle Cloud Infrastructure (OCI), Amazon Web Services (AWS), and Microsoft Azure. Oracle workloads can be run directly on these platforms through projects such as Oracle Database@Azure and Oracle Database@AWS, as well as dedicated interconnect services, thereby reducing latency and avoiding vendor lock-in. The current paper covers the opportunities and challenges of Oracle multicloud interoperability. It investigates building patterns, performance benefits, costs, and risks in a qualitative study based on technical documentation and case studies. The findings show that the Oracle strategy has the potential to enhance the portability of the workloads, disaster recovery, and agility. It requires a prudent approach to governance and integration practices. The article sheds light on the contribution of Oracle to changing the enterprise IT strategy and offers advice to the association that has to work in multifaceted multicloud settings.

Formation of Organic Nitrates Mechanism of the Process
type: item
description: The analysis of the literature, including our works, was carried out, on the basis of which this review article was prepared. Previously, the direct (radiochemical) method proved the participation of nitrate ion in the anodic process - the oxygen evolution reaction (OER). Of interest was the possibility of accepting NO3 radicals formed during electrolysis by other anion-radical particles. Salts of acetic and propionic acids were chosen as model objects. It was found that during electrolysis of acetate-nitrate (system 1) and propionate-nitrate (system 11) mixtures, the pH of the medium significantly affects the selectivity of the reactions. In an acidic medium during electrolysis of both systems at high potentials, nitrate ion acts as a source of active oxygen, which is used to form molecular oxygen and destructively oxidizes alkyl groups. In a weakly alkaline solution, during the electrolysis of an equimolar mixture of system 1, ethane is formed, the current output (CO) of which drops sharply and reaches a value of ~30%, and a small amount of oxygen. A significant part of the current is spent on the oxidation of CH3 particles with the formation of carbon dioxide (CO~60%) and water. In a weakly alkaline solution, the process of system 11 differs from system 1 and is interesting in that during the electrolysis of an equimolar mixture of propionate and nitrate, products of the interaction of nitrate radicals and propionate particles are formed with the formation of organic nitrates. Based on the analysis of the data obtained by a set of methods, a mechanism for the formation of organic nitrates is proposed.

Fundamental LCZ Mapping with ArcGIS-Based Spatial and Correlational Analyses to Study the Impacts of Infrastructural Area Maximum Volume (A-MV) Attributes on OTC – An Urban Aw Summer Case
type: item
description: The aim of this study is to map the study location stretches into 100mx100m local climate zones (LCZs) on the basis of primary observations and secondary photographic data for spatial analysis of various urban infrastructural elements (grey(G)-built structures, blue(B)-water bodies and green (Gr)-natural vegetation) and impact assessment of their estimated area (EA) and maximum volume (EMV)) on the air temperature (Ta) that characterizes the outdoor thermal comfort (OTC). Climate Modification by Urban Infrastructure, Fundamental Concepts of Urban Infrastructure Mensuration Parameters, Fundamental Concepts of Urban Grey Blue Green Infrastructure (UGBGI) and Concepts Of OTC, Koppen Classification and LCZs are the linked areas. Study locations are based on socio-economic and geophysical attributes. Initial 200 pilot survey responses regarding thermal sensation votes and other subjective details were used. Preferred values of Physiological Equivalent Temperature (PET) and optimum Ta have been used. After the mapping in ArcGIS and polygonal delineation of the areas, EA values were compiled in tabular format. Based on primary measurements and secondary studies, a maximum height (hmax) value was assigned to each sub-category for EMV evaluation. Statistically, the EA and estimated perimeter (EP) values were analyzed using QQ, scatter plots, histogram and generate near table tools in ArcGIS. EA and EMV values were correlated with mean Ta values by linear regression. The R-square values generated gave a clear idea about the extent of their impacts on Ta. From the established relationships and preferred PET and optimum Ta values, optimum EA, EMV and hmax values of the broader categories(G,B,Gr) required for preferred OTC levels were finally evaluated.

A New Propeller Design
type: item
description: Here a concept for a new propeller is presented. Instead of a single point where a propeller blade is fixed with the aircraft or the ship, I suggest a long axis. The axis runs horizontally. The blades are long rods. They are fixed at one side with the axis. Contrary to the usual propeller, a single propeller blade can be used. The blades may have an arbitrary length. It is limited only by the axis.

Oxidation of Nitrate Ions at a Platinum Anode
type: item
description: The analysis of available works in the literature, including our own, was carried out, on the basis of which this review article was prepared. The interest shown in the processes of oxidative synthesis at high anodic potentials is associated with the production of various types of organic and inorganic, including mixtures of organo-inorganic compounds. The problem of electrochemical introduction of the NO3 group into the molecules of organic and inorganic compounds, which are valuable products used in various fields of technology, is relevant. The electrochemical route to the synthesis of such compounds is complicated by the fact that, unlike perchloric and sulfuric acids, the anodic behavior of NO3 - has not been sufficiently studied. One of the reasons for this is the impossibility of obtaining reliable experimental data when using electrochemical cells in which the interelectrode spaces are separated by a glass porous diaphragm. The products of cathodic reduction, penetrating through the diaphragm into the anolyte, are oxidized by oxygen formed at the anode and significantly affect the reliability of the data obtained, in particular, the current yield (CO) of oxygen. Electrochemical cells in which the interelectrode spaces are separated by cation-exchange membranes have been developed and manufactured for the first time. In this case, the possibility of reduction products getting into the anolyte is excluded, which leads to reliable results. Only electrochemical cells of a new design, allowing reliable data to be obtained, were used in the studies. The direct (radiochemical) method proved the participation of nitrate ions in the anodic process - the oxygen evolution reaction (OER). It is shown that NO3 ions participate in the OER in two ways. The analysis of the complex of the obtained data made it possible to propose a mechanism for the oxidation of nitrate ions.

AI-Driven Threat Detection and Response for Healthcare: Securing Patient Data in Cloud Environments
type: item
description: Several healthcare organizations have started adopting cloud services, which has led to the emergence of this issue, with patient data privacy and security being the most crucial. Current conventional security operating models are more reactive and based on rules that do not suffice in the case of new and more complex threats in large systems dealing with big data from EHRs, connected smart devices, and heavily used patient care access. This paper provides a detailed overview of threat detection and response systems in the healthcare sector through the help of a powerful Artificial Intelligence system. The system utilizes ML models trained on past intrusion data from cloud-native services such as Amazon SageMaker, AWS GuardDuty, and Macie. It performs realtime threat detection on the client’s network and responds to them effectively while adhering to HIPAA standards. Such technological components consist of Federated Learning, an advanced method of training Machine Learning models without compromising the data owner’s privacy, Behavioural Biometrics as an improved method of identification and authentications, and Blockchain technology to provide an unchanging record of events. Realizations of the framework were performed based on both artificial and real datasets of a hospital to show that it outperforms traditional systems with 97.2% average detection accuracy, 70% less false positive rates, and saved hours, whereas the meantime for threat detection was reduced to seconds. The study also discusses AI’s use in real-time compliance monitoring, eradicating compliance issues and operational expenses. There exist great prospects for the further improvement of health care information security utilizing AI as an instrument for advances in early, continuous, and scalable actualisation of patient data’s cloud; as for other considerable further studies, there are tendencies in explainable models, intelligence federation, and quantum insensitivity of information protection.

Optimization of Inorganic Refrigerants in Cascade LNG Liquefaction Systems: A Response Surface Methodology Approach for Enhanced Energy Efficiency and Sustainability
type: item
description: The global energy transition has intensified the demand for sustainable liquefied natural gas (LNG) production, necessitating advanced refrigeration systems with minimal environmental impact. This study presents a comprehensive thermodynamic optimization of inorganic refrigerants (xenon, argon, krypton, nitrogen) in cascade LNG liquefaction cycles using response surface methodology (RSM). Through Aspen HYSYS modeling and I-optimal design experiments, key performance metrics—coefficient of performance (COP), cooling capacity, specific work, exergetic efficiency, and overall thermal efficiency—were evaluated across varying evaporating temperatures (−50°C to −30°C) and pressure regimes (10–30 bar). Results demonstrate that xenon achieves superior performance, with a COP of 3.6 and exergetic efficiency of 89% at optimal conditions (−44.5°C, 10.78 bar), outperforming conventional mixed refrigerants (C3MR) by 16.6% in specific energy consumption. Exergy analysis reveals that xenon minimizes irreversibility in compression and heat exchange stages, reducing exergy destruction by 21% compared to nitrogen. However, economic constraints due to xenon’s high cost highlight the trade-offs between efficiency and scalability. This work advances sustainable LNG production by identifying energy-efficient refrigerant alternatives while providing a robust RSM framework for industrial process optimization.

description: Objects with angular momentum (rotation) are known to exhibit an effect called Lense Thirring (LT) precession whereby locally inertial frames are dragged along the rotating spacetime. Such effect has been usually associated to celestial bodies, and especially studied in the case of black holes and neutron stars, but I show here that Lense Thirring precession can be also very relevant for small objects under some specific conditions. The precession effect is calculated for any object rotating around of one of its axes of symmetry, regardless of its rotation speed, mass and moment of inertia, showing that the influence of Lense-Thirring in such objects allows to create concavities and convexities in space-time around them. As consequence, the gravity effect over them can be counteracted or reinforced, experimenting effects equivalents to partial gravity, zero gravity and even anti-gravity. Kerr spacetime metric is applied with some limitations. Relevance of LT effect in function of morphology, colatitude, size, number of rpm and even kind of material is showed and an analysis of the results obtained is done. Consequently it’s proven that LT effect should be also taken on account to be applied not only to small objects but to space crafts designs. This study applies the same concepts involved in the Special Zero Gravity Theory but counteracting in this case the gravity with the consequences of applying Lense-Thirring effect instead simply spin. As consequence 1) A new generic concept is introduced: General Zero Gravity. 2) We also introduce a new view about Gravity and its origin based in accepting that Gravity can be considered to all effects an energy and that Gravity has evolved over Time till reach its current balance state. A close relationship among Gravity and kinetic energy is analyzed in detail. Then we compare the origins of concavities-convexities reached by rotation and “conventional” Gravity. We also analyze the relationship among Light and Gravity and Lig…

Inverted Weibull Poisson Distribution: Properties, Inference and Applications to Engineering Data
type: item
description: In this paper, a new two-parameter extended inverted Weibull distribution called the Inverted Weibull Poisson distribution is introduced using the Poisson generator. This method adds one shape parameter to a baseline distribution thereby increasing its flexibility and applicability in modeling lifetime data. We study the structural properties of the new distribution such as the mean, variance, quantile function, median, ordinary and incomplete moments, reliability analysis, Lorenz and Bonferroni curves, Renyi entropy, mean waiting time, mean residual life, stress-strength parameter, and order statistics. We use the method of maximum likelihood technique for estimating the model parameters of inverted Weibull Poisson distribution and the corresponding confidence intervals are obtained. Two lifetime data sets are presented to demonstrate the applicability of the new model and it is found that the new model has superior modeling power when compare to the Inverted Weibull distribution.

Securing BYOD (Bring Your Own Device) in Education: Endpoint Management for School Networks
type: item
description: The implementation of the Bring Your Own Device (BYOD) in learning institutions has brought significant changes in other learning institutions by giving the learners and faculty a chance to use the gadgets of their personal choice. The utilization of LBYG relies on the students’ personal and portable devices, which include laptops, tablets, smart phones etc, enhances the personalization of the learning process, improves the level of interest and the yields, hence productivity in the institutions. In the same respect, on the aspect of operational costs, schools do not require much investment in school-owned hardware owing to BYOD initiatives. This approach also ensures that the educational institutions can manage the available resources well and apply advanced technology to learning. However, the increasing use of BYOD has its issues that that need to be addressed, specifically, in relation to the usability of the connected devices in the school network in a compliant manner. However, BYOD comes with sever security risks that may endanger institutional information and learning processes. BYOD [Bring Your Own Device] give every bad guy a door point to breach into a network; corrupt, steal or destroy organizational data, or gain unlawful access to an organization’s IT system. This is due to the different types of devices, operating system, and software used by the students and staff which hampers the provision of measures towards containing some of the vulnerabilities. Also, if not properly taken, endpoint security can lead to the compromising of several student and faculty records which are legally sensitive information. This paper aims at explaining why there is a need to adopt effective management of End Point solutions to help in handling of these risks. In view of the insights drawn from the current research studies, analysis of the methodologies, real-life implementation strategies, introduce a broad defense solution that has been specifically designed for educat…

Integrated Process Optimization and Defect Analysis to Minimize Glass Jar Breakage in Acidified Gherkin Packaging Lines
type: item
description: Glass packaging plays a pivotal role in maintaining the safety, integrity, and market quality of acidified gherkin products. However, frequent glass jar breakage during processing and handling presents a critical operational and sustainability challenge in pickle manufacturing lines. This study was conducted at Global Green Company Limited, Bangalore, to identify, analyze, and minimize glass jar breakage through an integrated processoptimization framework. Breakage data were collected across two production lines and four critical points—pasteurizer outfeed, dud detector, downing area, and conveyor system. Quantitative evaluation revealed higher defect incidence in large-capacity jars (1400–2000 ml), with thermal shock and mechanical vibration being the most significant contributors. Implementation of corrective measures, including gradual cooling, conveyor synchronization, torque calibration, and operator retraining, resulted in an average 51.7% reduction in breakage, confirmed statistically (t = 3.49, p <0.05, Cohen’s d = 1.56). Post-intervention, the mean defect rate declined from 7.3% to 3.52%, improving line efficiency and reducing waste generation by 35%. The findings establish that systematic process optimization combining root cause analysis and engineering controls can effectively enhance packaging integrity, economic performance, and sustainability in glass-packaged food manufacturing.

Hypoglycemic Properties of Ethanolic and Aqueous Leaf Extractof Acanthus Montanus (Acanthaceae)
type: item
description: This study evaluated the hypoglycemic properties of ethanolic and aqueous leaf extract of acanthus montanus. The leaves were subjected to different extraction methods (ethanolic extract and aqueous extract) and evaluated the phytochemical and hypoglycemic potential of the aueous and ethanolic extract in alloxan‑induced diabetic rats. Flavonoid content varied widely, ranging from 12.03% in milled samples to 54.00% in ethanolic extracts with the latter being significantly higher (p < 0.05). Alkaloid levels followed a similar trend, spanning 2.06 % (milled) to 15.02 % (ethanolic extract) with significant differences among all samples (p < 0.05). Saponin content ranged from 5.00 % (ethanolic extract) to 19.00 % (aqueous extract), while tannins ranged from 1.03 % (aqueous extract) to 2.50 % (ethanolic extract); both showed significant variations (p < 0.05). In the animal study, Group A (normal control) maintained glucose levels within the normal range (3.8–7.8 mMol/L). Group B (alloxan‑induced) exhibited an initial drop 24 h post‑induction followed by persistent hyperglycemia (>7.8 mMol/L). Group C (standard drug) returned glucose to normoglycemia, while Group D (treated with ethanolic extract) showed a gradual decline from 9.8 mMol/L to normoglycemic levels (8.0 mMol/L) over two weeks. Alloxan selectively destroyed pancreatic β‑cells, confirming its use as a diabetic inducer. These findings demonstrate that ethanolic extraction maximizes flavonoids and alkaloids, and its extract possesses notable hypoglycemic activity, suggesting potential for developing anti‑diabetic phytomedicine.

Mitigating Data Quality and Consistency Challenges in Multi-Source Ingestion through Schema Validation and Transformation Techniques
type: item
description: Ensuring data quality and consistency across data intake from several sources presents a tremendous challenge for companies running large-scale data platforms. These challenges are exacerbated by the numerous data forms—structured, semi-structured, unstructured—that come from many sources—including relational databases, IoT devices, and APIs. Data variances, incompatible schemas, and quality issues cause poor analytics and downstream decision-making. With an eye toward how schema validation and transformation techniques might assist address problems with data quality and consistency across the pipeline, this paper looks at the primary challenges related to receiving multi-format data. We analyze schema validation systems including Apache Avro, JSON Schema, and Protobuf with real-time transformation techniques applied using Apache Kafka, Apache Spark, and AWS Glue. The limits of these techniques and future directions—such as AI-driven data validation and self-healing data pipelines are also discussed at the end of this work.

Implementation of Additive Manufacturing Workflows into the Prosthetic & Orthotic Industry: Case Study
type: item
description: The prosthetic and orthotic industry is evolving to include innovative technologies as solutions to material and labour usage, promoting more sustainable and cleanly practises for both staff and patients. 3D printing, scanning and software have revolutionised the workflows of clinicians, technicians and administrative staff. To determine the reliability and repeatability of additive manufacturing (AM) workflows in a P&O company, observation and interview analyses were undertaken within an established prosthetic and orthotic company. The collection of data from these opportunities offered valuable insight into workflow sessions, employee feedback and predetermined themes regarding both traditional and AM processes for the production of Transtibial prosthetic sockets. Findings revealed the reduction in workflow sessions, technician resource and storage requirements when working through AM processes, although there is a lack of opportunity and resource for clinicians and technicians to learn how to use these digitalised processes. Although both traditional and 3D printed sockets receive similar feedback from patients regarding comfort and fit, discrepancies in socket weight were noted. A further understanding on the culture and adoption barriers of AM processes should be investigated for clinicians, technicians and administrative staff across a larger sample size.

Critical Behavior of an Extreme Fire “Fire Junction”
type: item
description: In this paper the concept of extreme forest fire behavior denominated as Junction Fire is analyzed, this phenomenon consists of the interaction between two linear fire fronts which in their propagation intersect at a single point making a small angle between them. In their process of fusion, the phenomena of heat transfer by radiation and convection are extremely amplified due to the concentration of energy at the point of intersection. The concentration of energy and therefore the development of the powerful heat transfer mechanism induces an extremely high and sudden increase in the rate of spread until it reaches a maximum value after which begins to decrease. This behavior of the order parameter exhibits a non-universal phase transition. The analysis carried out in the ADIA-LEIF laboratories show that fires junction are a source of instability which leads to serious safety and management problems for those who are confronted with this type of forest fire. The results show that the fire junction spread exposed two main regimes; an initial acceleration phase characterized by a high rate of spread depends essentially on the initial angle between the fire fronts θ0 , which shifts during the evolution of the fire until the limit of creation of a single front of fire in a straight line explaining a decreasing phase. Nevertheless, the front fire dynamics depends both on the initial angle between the fire fronts θ0 and on the slope ground αJ exhibiting a non-universal phase transition known in the literature.

A Comparative Life Cycle Assessment of Hydrogen Production & Storage with Renewable Energy Source and Grid Electricity Source
type: item
description: The role of electricity is becoming significant in our advancing world. Currently, Ireland’s energy mix heavily relies on carbon-polluting fossil fuels, posing an environmental challenge. As per the Paris Agreement 2015, Ireland is ambitiously targeting to meet net zero carbon dioxide (CO2) emissions by 2050 and a 51% reduction by 2030. The country is shifting towards renewable energy sources to generate power to achieve this target. With abundant wind energy available, Ireland can meet its goal. However, due to the intermittent availability of wind energy, an energy backup for power generation is necessary. The use of curtailed or dedicated wind for producing hydrogen gas through electrolysis, and storing it in underground salt caverns is one approach to the problem. Northern Ireland has a rich source of Permian salt deposits offering a better place to store hydrogen which can be withdrawn for electricity generation, or used as fuel in transportation sectors. The Life Cycle Assessment (LCA) of the hydrogen systems can scrutinise the environmental impact of carbon emissions. This study analyses routes to reduce the environmental impact by evaluating polluting hotspots during the construction and operation phase of the system. This paper compares the impacts of the LCA on a hydrogen system which consists of a wind energy source for hydrogen production through electrolysis, transportation in pipelines and compression before storing it in salt caverns. A comparative analysis is carried out with the LCA of the hydrogen system with an electrical grid supply source. The results show that the impacts contributed by a renewable source are less than the electricity from the grid for the island of Ireland.

Advancing Coconut Dehusking Technology: A Dimensional Analysis-Based Parametric Model for Local Production
type: item
description: Effective dehusking is essential to the coconut industry's value chain, which is still a major industry in many tropical economies. Using dimensional analysis based on Buckingham's π theorem, this study proposes a novel mathematical model to forecast the dehusking efficiency of a locally made coconut dehusking machine. The model was created to help regional producers optimize their equipment for better output. The model was validated using experimental study data, showing a maximum correlation coefficient (R2 = 0.388) between the predicted and measured dehusking efficiencies. Despite this moderate correlation, the model showed strong applicability, enabling dehusking efficiency estimates with an astounding accuracy of up to 89.5%. This degree of accuracy indicates that engineers and manufacturers looking to improve coconut processing technologies may find it useful. By reducing material waste and boosting productivity in regional agricultural contexts, the work's implications go beyond simple efficiency gains and support sustainable production methods. Given the coconut's economic significance, the model is a useful tool for supply chain participants, especially in environments with limited resources. This research opens the door for future advancements in agricultural machinery design by using dimensional analysis to better understand dehusking mechanisms. All things considered, the creation and verification of this parametric model mark a critical advancement in the technological capacity of regional coconut production, which will ultimately promote sustainability and economic growth.
