Abstract: Food waste management is a contemporary global issue. According to UNDP, food waste constitutes 40-51% of the waste in the Kingdom, followed by paper, cardboard, plastics, and other materials. Consequently, an effective waste segregation system is essential to address this problem. This research proposal aims to develop a mechanism for the segregation of decayed fruits and vegetables from the shelves, storage, and inventories of retailers such as Hyper Panda, Carrefour , and Lulu hypermarkets, utilising a hybrid machine learning algorithm comprising Linear SVM and PCA, alongside YOLO for real-time detection. Following segregation, this organic waste may be transported to a biorefinery where, using anaerobic digestion technology, it can be turned into methane gas. Currently, the door-to-door accessibility of processed foods, consumer products, and groceries is in great demand. Consequently, this methane gas may be utilised by their own delivery trucks and vehicles, so minimising food waste reduction in retail, promoting energy sustainability, and decreasing pollution.

Abstract: With the advent of digital services, various vulnerabilities in centralized identity management systems such as Single Point of Failure (SPOF), data leakage, and user privacy invasion are evident. In this paper, an architecture framework for designing Decentralized Identity Management System (DIDMS) by leveraging blockchain technologies is proposed for privacy preserving authentication in digital age. The DIDMS framework makes use of Decentralized Identifier (DID) with Verifiable Credentials (VC) and Zero Knowledge Proof (ZKP) techniques to implement the concept of self-sovereign identity. Four phases of framework including registration, credential issuance, authentication and storage is designed and tested. The performance results obtained from the experimentation indicate that the proposed framework gives an authentication latency of 320 ms, storage overhead reduction of 42%, and verification accuracy of 98.6% with 31% gas optimization over conventional smart contract approaches. The comparative evaluation with existing frameworks indicates improvement in the areas of privacy protection, scalability and user control.

Abstract: Due to the increasing demands for energy in the world coupled with increased environmental regulations, it is now necessary to use sustainable energy sources instead of the traditional fossil fuels for internal combustion engines. In this paper, a study on performance improvement in compression ignition engines through the use of alternative biofuels has been presented. The study focuses on hydrotreated vegetable oil (HVO), biodiesel blends and the use of dual fuel where the two fuels used include biogas and hydrogen. The results of experimental and computer simulations show that the use of HVO leads to reduction of NOx and CO by 9.0% and 38.7%, respectively, compared to fossil diesel. Turbocharged B20 biodiesel blends lead to fuel consumption reduction of 20% and brake torque increase of 75%. The canola biodiesel gives brake thermal efficiency of 31.2% and brake-specific fuel consumption of 0.26 kg/kWh.

Abstract: Background- Essential hypertension is a major modifiable risk factor for cardiovascular disease and remains a leading cause of morbidity and mortality worldwide. Aerobic exercise is recommended as a first-line non-pharmacological intervention for blood pressure management. However, evidence comparing the effectiveness of low-intensity and high-intensity aerobic exercise on cardiovascular and functional outcomes remains limited, particularly in the Indian population. Objective- To compare the effectiveness of low-intensity and high-intensity aerobic exercise on blood pressure, functional capacity, cardiorespiratory fitness, resting heart rate, body mass index (BMI), and health-related quality of life in adults with essential hypertension. Methods- A prospective comparative pre-post study was conducted among 60 adults aged 40–65 years with essential hypertension. Participants were allocated into two groups (n = 30 each). Group A performed supervised low-intensity aerobic exercise (40–55% heart rate reserve), whereas Group B performed supervised high-intensity aerobic exercise (70–85% heart rate reserve) for 12 weeks. Outcome measures included systolic blood pressure (SBP), diastolic blood pressure (DBP), Six-Minute Walk Test (6MWT), estimated VO₂max, resting heart rate (RHR), BMI, and Short Form-36 (SF-36) quality-of-life scores. Assessments were performed at baseline and after completion of the intervention. Data were analysed using paired and independent Student's t-tests, with statistical significance set at p < 0.05. Results- Both exercise programmes produced significant improvements in all measured outcomes (p < 0.001). In the low-intensity group, mean SBP decreased from 146.8 ± 8.7 mmHg to 136.4 ± 8.1 mmHg, whereas the high-intensity group demonstrated a greater reduction from 147.3 ± 9.1 mmHg to 128.1 ± 8.8 mmHg. Functional capacity improved significantly, with the 6MWT increasing from 418.6 ± 52.3 m to 456.7 ± 52.1 m in Group A and from 421.7 ± 50.8 m to 490.8 ± 48.6 m in Group B. Significant improvements were also observed in VO₂max, resting heart rate, BMI, and all SF-36 domains, with superior outcomes in the high-intensity exercise group. Conclusion- Both low-intensity and high-intensity aerobic exercise are effective physiotherapy interventions for improving blood pressure control, functional capacity, cardiorespiratory fitness, body composition, and health-related quality of life in adults with essential hypertension. High-intensity aerobic exercise demonstrated significantly greater improvements across all outcome measures, supporting its use in appropriately screened and supervised patients.

Abstract: Despite the widespread adoption of chatbots for customer service, small businesses continue to lack the resources required to develop and customize such solutions effectively. In this work, we propose an approach that enables small businesses to construct tailored customer service chatbots by fine-tuning an open-weight large language model (LLM) using QLoRA [1] on a domain-specific customer service dataset. The proposed method leverages parameter-efficient transfer learning to adapt a pre-trained LLM to the customer service domain, preserving its general natural language understanding and generation capabilities while specializing its behaviour. To extend the chatbot’s functional scope beyond the fine-tuning corpus, we integrate a Retrieval-Augmented Generation (RAG) [4] module that retrieves relevant product information, warranty details, and installation guides from PDF documentation at inference time. This allows the chatbot to ground its responses in accurate, business-specific information rather than relying solely on parametric knowledge. In addition, we log chatbot conversations and apply sentiment analysis to the resulting interaction data, forming a feedback loop that surfaces unsatisfactory exchanges for human follow-up and informs iterative improvement of the system. Taken together, these components constitute a cost-effective pipeline through which small businesses can deploy personalized customer service chatbots without incurring the cost of large-scale data collection or bespoke system engineering.

Abstract: A new series of transition metal complexes derived from 2-fluorobenzylidene)-2-(2-(hydroxyimino)-1,2-diphenylethylidene)hydrazine-1-carbothiohydrazide (FBHT) was successfully synthesized and systematically characterized using a range of spectroscopic and analytical techniques. The complexes were obtained through the reaction of the FBHT ligand with copper(II), zinc(II), and nickel(II) salts in a 1:2 metal-to-ligand molar ratio. Comprehensive characterization was carried out by elemental analysis, UV–Visible spectroscopy, Fourier-transform infrared (FT-IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, and mass spectrometry to confirm the structures and coordination behavior of the synthesized compounds. The electronic absorption spectra of the metal complexes exhibited noticeable shifts relative to the free ligand, providing clear evidence of successful metal coordination. Infrared spectral analysis further supported complex formation by displaying new absorption bands in the low-frequency region, which were assigned to metal–ligand vibrations involving the hydroxyimino and thiohydrazide donor sites. Moreover, the 1H and 13C NMR spectra revealed significant changes in the chemical shifts of the ligand signals following complexation, indicating alterations in the electronic environment caused by coordination with the metal ions. The antimicrobial potential of the synthesized complexes was assessed against representative Gram-positive and Gram-negative bacterial strains, namely Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, as well as the fungal pathogen Candida albicans, using the disk diffusion assay. All of the metal complexes demonstrated enhanced antimicrobial activity compared with the uncoordinated ligand. Among them, the copper(II) complex exhibited the strongest inhibitory effect, particularly against S. aureus and P. aeruginosa. This enhanced performance was further confirmed by lower minimum inhibitory concentration (MIC) values compared with the corresponding zinc(II) and nickel(II) complexes. In contrast, the free FBHT ligand displayed only weak antimicrobial activity, highlighting the beneficial role of metal complexation in improving biological efficacy. Overall, these findings suggest that the synthesized FBHT transition metal complexes, especially the copper(II) derivative, represent promising candidates for the development of novel antimicrobial agents.
