In this research, a current and voltage ratio analysis-based approach to condition monitoring and defect detection for photovoltaic (PV) systems is presented. To estimate the expected electrical parameters of the PV array, a prediction model is created utilizing module temperature and plane-of-array irradiance. Real-time measured data from a hardware PV monitoring setup established at Manipur Technical University is compared with the projected values. By comparing normalized current and voltage ratios to predetermined thresholds, string faults and module bypass circumstances can be found. When there is no issue, the measured ratios stay within the healthy range, but when there is a fault, there are noticeable variations. The suggested model is validated by the strong match between the measured and anticipated power. The findings demonstrate that, without the need for sophisticated algorithms, the ratio-based technique offers a straightforward, affordable, and efficient means of early defect identification and real-time PV system health monitoring.
The electric vehicle market is swelling rapidly all over the world. The need for the charging infrastructure is also increasing rapidly as interest in electric vehicles increases. Range anxiety is one of the issues faced by electric vehicle users. The charging station in the most remote location in any country is lagging due to a lack of electrification or transportation infrastructure. Thus, the needs of a portable charging station come into the picture. The portable charging station does not mean the charging system and the source will be put in the vehicle, but a vehicle can be charged at any location where there is no charging station. One of the approaches for the portable charging station or system is a Vehicle-to-Vehicle (V2V) charging system. In this technology, one vehicle can charge another vehicle during parking or driving, as per the convenience of both vehicles. This charging can be done using wireless charging or wired charging during parking. Moreover, dynamic wireless charging is also possible between vehicles. In this paper, a comprehensive review is made of the recent research trends in V2V charging, and opportunities and challenges faced during the implementation of the V2V charging system are highlighted. The main concept of this technology is that any vehicle can act as a load as well as a source, and the energy management can be more efficient, and the requirement of charging stations can be fulfilled in remote locations where the charging stations are not set up yet.
Maximum-type nonlinear contractions in real-valued b-metric spaces depend essentially on the total order of [0,∞ ). Such conditions cannot be transferred directly to cone-valued distances, since a general ordered Banach space is only partially ordered and finite maxima of cone elements need not exist. This paper develops a cone b-metric fixed point framework that avoids this obstruction by separating intrinsic cone-order arguments from scalar-gauge reductions. The main theorem is a nonlinear comparison principle governed by an order-preserving map Ψ :P→ P whose iterates satisfy an s-Picard summability condition. It yields existence, uniqueness, constructive Picard convergence, and a posteriori cone-order error estimates without assuming linearity, additivity, or homogeneity of the comparison mechanism. As structured consequences, we derive positive operator-valued contractions and an operator-valued Reich-type theorem involving the resolvent ℛ=(I-B)^-1(A+B) under the spectral condition r(ℛ)<1/s. Maximum-type nonlinear contractions are then recovered only after nonlinear scalarization, where real maxima are well defined. The framework also gives Ulam–Hyers stability, data-dependence estimates, examples over the positive cone of C[0,1], and an application to a Caputo fractional Volterra-type initial value problem. In the application, the positive fractional Volterra majorant has spectral radius zero, so uniqueness follows without the customary scalar smallness condition on the Lipschitz bound, fractional horizon, or interval length.
In this article, we fabricate a p-n junction photodetector (pn-PD) and a metal-semiconductor-metal photodetector (MSM-PD) based on WO3 nanowire using the glancing angle deposition (GLAD) technique in the E-beam evaporation system and compare their performances. From the UV photodetector analysis, the calculated responsivity, external quantum efficiency (EQE), detectivity, and noise equivalent power (NEP) of pn-PD/MSM-PD are similar to 190/18 A/W, 604/58.5, 1.52 x 10(14) Jones/5.12 x 10(11) Jones, and 9.13 x 10(-14)/3.38 x 10(-12) W, respectively, at the reverse biasing voltage of 2 V under the UV (390 nm) illumination. The rise time/fall time of pn-PD and MSM-PD are 94/102 ms and 35/65 ms, respectively. The pn-PD gives higher responsivity and EQE over the MSM-PD due to the generation of a large photocurrent in the depletion region formed in the p-n junction, which generates a built-in electric field that separates the photogenerated charge carriers. Despite this, our MSM-PD also gives comparable detectivity and NEP with pn-PD and exhibits excellent performance suitable for high-speed UV detector applications.
