This study introduces a novel framework for auto-tagging images that integrates both spatial and visual properties to generate comprehensive and accurate tags. The framework operates through four phases: extraction, abstraction, composition, and assessment. Our research highlights the benefits of combining visual and spatial analyses, demonstrated through a case study using geo-tagged urban street images from Orlando, Pittsburgh, and Manhattan. Experimental results show that the proposed framework significantly enhances the accuracy of keyword-based searches compared to conventional methods. In particular, based on our experiments, image search using the tags generated by our proposed framework, referred to as descriptive tags, achieved an average precision improvement factor of 0.9 compared to conventional tags. Additionally, our proposed ranking algorithm, which extends the term frequency-inverse document frequency (TF-IDF) algorithm, resulted in improvement factors of 0.86 for mean average precision (MAP) and 0.57 for mean reciprocal rank (MRR). Moreover, our framework’s flexibility and robustness make it suitable for diverse applications, from smart cities to online shopping.

Transformers have historically employed solid insulators like paper and pressboard as well as mineral or synthetic oil. However, the development of ecologically friendly insulating materials has been spurred by new environmental regulations as well as economic benefits. This research investigates the use of sol-gel synthesized aluminium oxide (Al₂O₃) nanoparticles to improve the insulation properties of host transformer oil. The synthesized aluminium nanoparticles were characterized with X-ray diffractometer (XRD) and found rhombohedral structure, whose chemical composition was studied by energy dispersive X-ray spectrum (EDAX). Investigation using Fourier transform infrared spectroscopy (FTIR) also revealed the production of AlOOH and hydroxyl vibrational bands at wavenumbers of 690 and 2976 cm^-1, respectively. Studies using field emission scanning electron microscopy (FESEM) showed that the nanoparticles are spherical in form and have a diameter of around 38 nm.

In this study, pure and Cu-doped iron oxyhydroxide was synthesized by the co-precipitation method and was successfully applied for the decontamination of phosphate from aqueous solutions. The solid sample was characterized using a surface area analyzer, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), pH_iep, and Fourier transform infrared (FT-IR) spectroscopy. The results reveal that the surface area of iron oxyhydroxide increases from 35.1 m²/g to 126 m²/g with Cu ion doping, which may be due to the difference in ionic radii of Fe⁺³ (0.645 Å) vs. Cu⁺² (0.73 Å), thus creating crystal defects. The isoelectric point (pH_iep) for the Cu-doped sample was found to be 3.05 in 0.1M KNO₃ and decreased to 2.5 when treated with phosphate anions in solution. Elemental analyses confirmed by XPS indicated that 0.1% by weight Cu was incorporated into the doped iron oxyhydroxide, changing the overall surface parameters. The adsorption process was evaluated with different doses of Cu-doped iron oxyhydroxide, contact time, phosphate anion concentrations, and pH of solution over a range of temperatures (303–323K). The adsorption of phosphate increased with increasing phosphate anion concentrations and decrease with increase in temperature. Langmuir models fittedthe adsorption data well with a good correlation coefficient (R² = 0.99). The sorption maxima for pure iron oxyhydroxide were found to be 0.04 mmol/g at pH 3 and 303K. With Cu ion doping, sorption maxima increased elevenfold to 0.442 mmol g⁻¹ at 303K. Thermodynamic specifications indicated that the sorption process was spontaneous and endothermic in nature. Thermodynamic parameters were evaluated from the Langmuir constant X_m (mmol.g⁻¹) and B (L.mmol⁻¹).
