These parameters affect the transmission corridor width and hence play a vital role in deciding Right of Way. In this paper computational model and working GUI using MATLAB as a programming platform is developed. The software developed here requires only basic data related to any transmission configuration. This novel GUI is capable of computing the values of Electric and Magnetic Fields along with Radio Interference and Audible Noise for different tower configurations like single circuit horizontal, double circuit vertical etc. Lateral, Longitudinal as well as 3D profile of different field effects and corona effects can be plotted and analyzed for further calculation of Right of Way of UHVAC Transmission Line.

According to certain research reports, algal products used in cosmeceuticals have been known to be suitable alternatives with constructive effect even after prolonged usage. Many algal species have the antiwrinkling, anti-aging, photo protection, whitening agents which are widely used in the cosmetics. This review basically focuses on the applications of the algal components extracted from macro marine algal species for its use in the cosmetics.

The model used herein represents a new approach toward addressing singular perturbation problems in dynamics. The experiments involve trapping microbeads at the focal point of an optical tweezer/trap. The optical trap can accurately measure the position of a microbead only in two directions. Given experimental data, the model can be used to estimate the bead’s position in the third direction. This estimate allows an examination of the full position, velocity and acceleration of the bead, which in turn allows and investigation of its particle Reynolds number (Rep). It is generally believed that a low Rep implies that a small bead will exhibit overdamped motion. The velocity estimates obtained herein for three bead diameters, 1950nm, 990nm and 500nm, provide new insights into the interpretation of a low Rep in light of the underdamped motion observed in experiments.

Stipulation of manufacturing processes has increased now days. Optimization is very essential thing in manufacturing processes. Due to optimization accuracy, productivity can be increased. Honing is a super finishing manufacturing process. Honing provides proficient surface finishing of the cylinder liner. Main purpose of honing is to give prevention against the leakage of oil. So, it can be stated that honing is used for the purpose of oil retention in cylinder liner. Hence utilization of oil is decreased. By optimization of honing process by optimization technique, parameters will be optimized and production rate of GG25 cylinder liner will be increased.

Research paper thumbnail of Distribution-Free Sufficiency in Sampling Finite Populations

Uncorrelatedness in Godambe's definition is shown to be equivalent to statistical independence, as is claimed on the author's behalf in the appendix to Godambe's paper. But the second result claimed there, that every DF-sufficient estimate must necessarily be of the form a(s). I Xi +b(s) iES is false, as the complete class of DF-sufficient estimates consists of estimates which involve all the variates represented in the sample. This second result, however, remains valid with an alternative definition of DF-sufficiency. A second alternative definition is also discussed.

However, this approach can be time-consuming and inefficient, as patients with minor illnesses can take up valuable resources that could be better used to treat more serious cases. As a result, this research proposes a new approach to disease prediction using machine learning and symptom-based analysis. The goal is to develop a predictive model that can accurately identify potential diseases based on a patient's symptoms. This model utilizes machine learning techniques to analyze and process symptom data, allowing for quick and precise disease prediction. The study uses a large dataset of patient symptoms and medical records to train and test the model, which demonstrated high accuracy in predicting diseases. The results of this study suggest that the proposed model could be a useful tool for early diagnosis and treatment of diseases, with the potential to improve healthcare outcomes. Overall, this research represents an important contribution to the field of healthcare informatics, with possible applications in disease prevention, treatment, and management.
