In the present situation, a lot of research has been directed towards the potency of plants. These natural resources contain characteristics valuable in combat against a number of diseases. But due to lack of familiarity of these plants among human beings, an appropriate advantage of their significance cannot be drawn away. Plants also shares the certain similar characteristics of leaves like color, texture, shape or size, making them hard to classify them among others. So, to eradicate this problem, a deep learning model has been used for the purpose for classification of different plants species captured in real-time using internet of things practice. Six different plants namely Ashwagandha, Black Pepper, Garlic, Ginger, Basil, and Turmeric has been selected for this purpose. Our proposed convolutional neural network (CNN) model achieved higher performance with an accuracy of 99
Numerous novel technologies, including self-powered implanted sensors and wireless sensor networks (WSNs) have evolved over the past decade. Due to the complications related to charging and maintaining batteries, these devices generally include a continuous power supply to operate consistently and safely. A viable solution may involve piezoelectric energy harvesting derived from vibrations produced by artificial technology, human motion and environmental factors. This paper presents the inaugural integration of piezoelectric polyvinylidene fluoride yarn-braid within the FRPC structure. The developed smart composite demonstrates its multifunctional capabilities, encompassing structural reinforcement, vibration attenuation, and energy harvesting. Testing subjected to cyclic loading circumstances of 5 to 22.75 Hz produces a power density of 3.1 mW/cm³ and an AOV of 3.8 V when strains are below 0.27
Rock mass behavior under sustained loading at the edge of slope for discontinuous joints is difficult to assess under unconfined condition. The current study is conducted on rock mass with orthogonal joint sets with one continuous and other discontinuous joint. Rock mass joint sets angles varies from 30° to 90° with the increment of 15° up to 90°. Experimentation shows failure pattern as well as load carrying capacity in such conditions. Mode of failure is the most essential parameter which governs the load carrying capacity of the rock mass specimen. The load intensities were calculated analytically for joint angles of 90°, 75°, and 60° using Euler’s method, resulting in percentage errors with experimental results of 7.93
This research examines the application of treated recycled aggregates (TRAs) in concrete to decrease the consumption of natural aggregates, thereby promoting sustainability and improving material life cycle management. A novel two-stage mixing process is utilised, beginning with the pre-soaking of recycled aggregates in 3% acetic acid for 72 h to weaken the adhered mortar. This is succeeded by mechanical grinding using wire mesh brushes and iron balls in a drum mixer to enhance the quality of the aggregate. Experimental findings indicate that an increase in TRA replacement leads to a decline in workability, density, and durability. The slump reduces from over 75 mm at 0%–20% replacement to 50 mm at 50%–60%, and the density decreases from 2400 kg/m³ to below 2250 kg/m³. Water absorption increases from below 6% to 8%, resulting in a rise in sorptivity from 2% to 3.5%. Experimental analysis indicates that a 20% replacement of TRA and a revolution time of 20 min are optimal, resulting in a compressive strength of 50–55 MPa. Response surface analysis indicates significant effects of TRA replacement and revolution time (p-values < 0.05), demonstrating strong model reliability (R 2 > 0.90, low root mean square error).
A systematic comparative investigation of polycrystalline Bi-0.La-9(0).1Fe1-xMxO3 (M = Mn, Nd, Co, Ni) synthesized via citrate combustion and solid-state reaction routes is presented. X-ray diffraction with Rietveld refinement shows that La substitution stabilizes the rhombohedral R3c structure and suppresses Bi-rich secondary phases, while B-site doping introduces lattice distortion and microstrain. These structural changes modify Fe-O-Fe bonding, as reflected in Raman spectra. Magnetic measurements reveal the emergence of weak ferromagnetism in doped compositions, likely associated with modification of the magnetic spin structure. Co-doped samples exhibit the highest value of magnetization (M-max similar to 3.75 emu g(-1) at 5 T) and an increased Neel temperature (similar to 740 K), whereas Mn substitution leads to large coercivity (similar to 7000 Oe) associated with enhanced magnetic anisotropy and domain-wall pinning. Ni doping results in moderate magnetization with T-N similar to 650 K, while Mn doping lowers T-N to similar to 622 K. For all compositions, citrate-derived samples show a stronger magnetic response than solid-state samples, primarily due to smaller crystallite size and enhanced contributions from uncompensated surface spins. These results demonstrate that combined chemical substitution and synthesis-route control effectively tune the structural distortion and magnetic behaviour of La-doped BiFeO3.
