Kinematic Relations of Particle Motion using Polar Cylindrical Coordinates System: Applications in Robotics and AI
Abstract: This paper explores the motion of a particle in space using the cylindrical polar coordinate system. It presents the physics of particle motion by defining spatial positions in three-dimensional polar coordinates and examining the particle’s kinematics—namely its position, velocity, and acceleration—in vector form. These quantities are mathematically expressed as functions of time, accounting for the changing coordinates in radial, angular, and vertical directions. This coordinate system proves especially useful for …

China’s Economic Performance (2020–2024): A Sectoral Index Analysis
Abstract: This study applies Laspeyres, Paasche, and Fisher ideal indices to China’s official 2020–2024 price and quantity data, quantifying sectoral inflation and real growth in agriculture, manufacturing, services, exports, and investment. Results show manufacturing experienced mild deflation (Laspeyres ≈ 98.7, implying ≈ 1.3% overall price decline) with a slight real output drop (~6.1%). A key driver was a sharp 21.4% fall in electric vehicle unit prices, despite +523% volume growth. Services …

A Sustainable EOQ Model for Declining Products Incorporating Cubic Demand, Variable Deterioration, Partial Backlogging, and Carbon Emission Optimization
Abstract: In this paper proposes a sustainable Economic Order Quantity (EOQ) model for inventory systems involving decaying items under cubic time-dependent demand, variable decaying rates, and partial backlogging while absolutely considering carbon emission costs. The model reflects practical market actions where demand initially increases and afterwards declines over time, and decay depends on the age of the item. To demonstrate the current model's applicability as well as evaluate the trade-off between …

Hazards of Power Production-A comparative study
Abstract: Nuclear energy has played a major role in reducing the world's use of oil for electricity generation over the past decades. Current estimates are that uranium resources will last some 400 to 500 years at the present rate of use. This resource base could, furthermore, last some 50 times longer if breeder reactors are introduced. Of the main energy sources, namely coal, hydro and nuclear, nuclear can be even considered …

Computer Programming Tool for the Design of Concrete Mixes for Pavement Quality Concrete Roads in India
Abstract: Basically concrete is a mixture of cement, sand, aggregates and water. These constituents bonds together and hardens with time and give strength to structure. The proportioning of concrete mixes consists of determining relative quantities of materials to be used. Thus to calculate proportions of various components of concrete several mix calculations are required to be performed. Consequently, it is not possible to select at once the exact mix proportion required …
