This research aims to improve the quality of life for visually impaired individuals by identifying obstacles in an indoor environment using a solution approach. The approach uses a Convolutional Neural Network (CNN) to extract features and detect objects from real-time video. A head-mounted image acquisition device detects objects and provides audio information to the visually impaired. The system processes live video streams frame-by-frame, processing each frame as separate images. The authors incorporate additional variables into a novel two-step iterative approach to solve complex computer vision problems. The proposed method improves computational efficiency and accuracy, opening up promising avenues for future research. The paper also presents a new mathematical formulation of curve and surface reconstitute algorithms by introducing auxiliary variables. Moving object detection is crucial for intelligent video monitoring systems, as it allows for accurate extraction of foreground objects. This paper aims to detect real moving objects from un-stationary backgrounds, limiting false negatives and achieving maximum application independence. The model and motion of the target objects are assumed to be unknown. Introduce a new mathematical formulation for curve and surface reconstruction algorithms, introducing auxiliary variables and minimizing energy. This approach transforms an implicit data constraint into an explicit convex reconstruction problem, simplifying it. The formulation also allows for more precise parameter settings, ensuring convergence to a minimum. And demonstrate the properties and results of this new auxiliary problem, mainly when the potential is a function of the distance to the closest feature point. [ABSTRACT FROM AUTHOR]

This is an era of globalization. At present the market growth in our country is remarkable. But sometimes we see some fickleness in market because taste and choice of consumers are changing nowadays. And market is very much dependent to consumers' taste and choice. Taking steps according to consumers' is very necessary in business market. One of the most important and successful applications of quantitative analysis to solve business problem has been in the physical distribution of products, commonly referred as transportation problems. The purpose is to minimize the cost of shipping goods from one location to another so that the needs each arrival area are met and every shipping location operates within its capacity. We could set up a transportation problem and solve it using the simplex method as with any Linear programming problem. But the special structure of the transportation problem allows us to solve it with a faster, more economical algorithm than simplex. This work is on comparative study of determining transportation cost by different methods and choosing those methods which offer least cost and maximize the profit. [ABSTRACT FROM AUTHOR]

Magnesium alloys, particularly AZ61 alloys have been widely used in the transportation industry. In the present study, the effect of aging treatment on the microstructure and mechanical properties of AZ61 alloys with silicon (Si) addition was studied under different temperatures and times. The aim of this paper is to improve the properties of Magnesium AZ61 alloys with Si addition. For this investigation, samples were cast, solution treated and hot rolled. Then the samples were aged at 180°C and 220°C for different time periods. Microstructures were investigated using optical microscope and scanning electron microscope. Micro hardness was measured by a Vickers Hardness tester machine. It is observed that Si modifies the Chinese script shape Mg2Si phase in the AZ61alloy. The morphology of the Mg2Si phase in the alloy changes from the Chinese script shape to the short pole and block shape due to the solution treatment which was performed at 410°C for 20 hours. All the three alloys exhibit maximum hardness, after aging treatment at 180°C for 19 hours and 220°C for 16 hours. However, the rate of increase of hardness is found to be higher at high temperature. AZ61 alloy shows the maximum hardness than those of Si added AZ61 alloys. The structure and property relationship with aging treatment are also discussed. [ABSTRACT FROM AUTHOR]
