Effective processes generate steady power. This new programme determines the dynamic performance of this technology's application to conduct a thorough feasibility utility grid is determined under different operational circumstances. However, integrating renewable energy into the alternating current system has challenges including voltage increases, synchronisation, and protection. With the DCDC converter, the power distribution system will be more reliable. The RES voltage level and storage needed by the static power DCDC converter must be maintained to preserve grid synchronisation. Because static converters are simple, they need a separate converter for stabilisation, increasing the circuit size. Compact size, centralised control, and energyefficient energy management are important features of Multiport Converters (MPC). The microgrid needs a backup battery to offset the intermittent nature of renewable energy sources. To ensure safety, isolation between the source and the load is required. Storage devices need a twoway power channel. An independent multiport converter is needed for the connected operation of the battery equipment and the utilisation of various renewable energy sources. The benefits of higher power density and separation of the nonisolation circuit allow for a smaller total circuit size. This paper summarises the multiport DCDC converter design for RES harvesting in a DC microgrid and makes research suggestions.

When materials are scaled down from their bulk form to the nanoscale, scientists have seen a number of unexpected and unusual behaviors shown by them. Many molecular devices have functional qualities that have been hypo research articled using computational modeling technologies, such as molecular rectifying, negative differential resistance (NDR), and switch behaviors in many cases. A growing number of low-dimensional materials (or nanomaterials) such as graphene, carbon chain (or nanowires), and carbon nanotubes have received considerable interest in recent years, primarily in the context of practical applications and theoretical study. At the same time, researchers continue to struggle to come up with a structure and modulation of their properties that is relevant. Recently, the remarkable capabilities of carbon-based materials have drawn a great deal of interest, since their applications and functions indicate that they have the potential to replace silicon-based electronic components in the future. It is possible to construct molecular devices as small as nanometers in size and that are freestanding, readily adjusted, have great stability, and are preferred to conventional molecular devices. With the use of an atomistic-level computational technique, the research effort reported in this research article aims to predict the electrical and transport characteristics of a range of nanometer-scaled devices. Experiments using carbon-based materials, such as carbon nanotubes, to determine their transport characteristics.

With five generations of wireless networks, remote operations, real-time control, and data collection will be ultra-reliable and low latency. Using 5G radio, digital twins, hardware-in-the-loop development, and our own experiences with the system, we show how a remote mobile machinery control system works. According to our findings, future 5G networks will have a significant reduction in latency and jitter compared to existing LTE infrastructure when using a proper edge computing architecture.

Farmer has wide range of diversity to select suitable crops. However, cultivation of these crops for optimum yield and quality produce is highly technical by using technical support. Detection of plant disease is an essential research topic. Studies show that relying on pure naked-eye observation of expert to detect such diseases can be prohibitively expensive, especially in developing countries. Providing fast, automatic, cheap and accurate image processingbased solutions for that task can be great realistic significance. This paper presents computationally efficient method for paddy leaf disease identification. The proposed approaches consist of three phases: image segmentation, feature extraction and classification. Image segmentation technique is used to detect infected parts of leaf by using K-means clustering. The feature extraction phase derives features based on the paddy leaf image. These features are used as input to the classifier for cla...

In 1990’s astronomical observation and theoretical calculation was leading astrophysicists to believe that not only the dark matter but also there is vacuum empty space filled in universe that is dark energy. It is suggested that the apparently disparate cosmological phenomenon attributed to so called “dark matter” and dark energy arise from quantum level of space -time itself. This creation of space time results in metric expansion. A recent modification of Einstein’s theory of general relativity by Chadwick, Hodgkinson and McDonald incorporate space time expansion. Recent evidence predicts that apparent amount of dark matter increases with age of universe. In addition proposal leads to the same result for the small but non-vanishing cosmological constant, related to dark energy.

In most of the cases, during acquisition process in industrial automation, the SPN may affects surface image. For elimination of noise present in the surface/work-piece image, various filtering methods have been used by many researchers. Here, a pixel density-based trimmed median filter (PDBTMF) was proposed, which works in the two different stages. In the first stage, the test pixel is diagnosed whether it is corrupted by the salt and pepper noise (SPN) or not (value of the test pixel is 0 or 255). In this paper, a 3 × 3 window is taken as the processing pixel as a center element and check for the similar pixels in the window. This algorithm works well for low-to-high-density impulse noise levels. The proposed algorithm, PDBTMF for reduction of noise in images shows good results in the elimination of SPN in grayscale, color images. The results obtained from the proposed PDBTMF shows better results as compared with the present existing methods such as adaptive weighted mean filter (AWMF), Decision Based Unsymmetrical Trimmed Variants Filter (DBUTVF), modified decision-based unsymmetric trimmed median filter (MDBUTMF), and Noise adaptive fuzzy switching median filter (NAFSMF). The proposed method, PDBTMF is experienced alongside various grayscale images and the color images and it exhibits a high Peak Signal-to-Noise Ratio, low mean square error and better Structural Similarity Index, image enhancement factor and Correlation Index.
