Curves And Surfaces Representation And Application
The document discusses curves and surfaces from mathematical and manufacturing perspectives. It introduces common curve types like circles and their parametric, implicit, and explicit representations. It also discusses curve properties like tangents and normals. Additionally, it covers the manufacturing process and sources of error at different stages from design to inspection. Representation of curves and surfaces is important for both analysis and manufacturing applications.
Surface representation
Bezier surfaces are parametric surfaces used in computer graphics and CAD/CAM. They are based on Bernstein polynomials and control points. A Bezier surface is defined by a grid of control points that determine the shape of the surface. Changing control points modifies the shape globally. B-spline surfaces allow for more local control and ensure continuity between patches. Coons patches interpolate between four boundary curves to generate a smooth surface. Sculptured surfaces are used for complex, free-form shapes and consist of blended parametric surface patches.
curve two
The document discusses several types of parametric surfaces used to represent 3D objects:
- Parametric bi-cubic surfaces include Hermite surfaces, Bezier surfaces, and B-spline surfaces which are represented using control points and parameters.
- Quadric surfaces are described by second-degree equations and include common shapes like spheres, ellipsoids, and cylinders.
- Surface of revolution objects are generated by rotating a 2D shape like a line or curve around an axis, producing shapes like cylinders and tori.
- Sweep representation involves sweeping a 2D shape through a region using transformations like translation, scaling, or rotation.
Unit i computer aided design
The document discusses computer aided design (CAD) and computer integrated manufacturing (CIM). It provides an overview of CAD concepts including wireframe modeling, surface modeling, and solid modeling. It describes the desirable features of a CAD package such as geometric modeling features, editing capabilities, display controls, drafting tools, programming interfaces, and analysis features. Common CAD commands and modeling techniques are also summarized.
Wireframe models
Wireframe models represent 3D objects using geometric primitives like points, lines, and polygons. They connect vertices with edges to form polygonal nets or meshes. There are three common representations: explicit vertex lists that store each vertex coordinate; polygon listings that define polygons through vertex indices; and explicit edge listings that store each unique edge and define polygons through edge indices. Wireframe models are easy to create but cannot represent curved surfaces or differentiate interior/exterior.
Geometric model & curve
This document discusses geometric modeling and curves. It provides information on:
- Geometric modeling is the process of creating mathematical models of physical objects and systems using computer software.
- There are different types of geometric models including wireframe, surface, and solid modeling.
- Curves can be represented mathematically in both implicit and parametric forms, with parametric being most common in modeling as it overcomes limitations of other forms.
- Parametric curves define a curve using a parameter, where varying the parameter provides points on the curve. Common parametric representations include lines, conics, and higher-order curves composed of simpler curve segments.
Introduction to solid modeling
This document discusses different methods of 3D modeling, including wireframe modeling, surface modeling, and solid modeling. It provides details on each modeling method, including their advantages and disadvantages. For example, wireframe modeling only contains edge information and cannot represent actual solids, while solid modeling defines enclosed volumes and allows simulation under real-life conditions. The document also covers specific solid modeling techniques like boundary representation and constructive solid geometry, as well as parametric modeling concepts.
Bezier curves
Bézier curves are parametric curves defined by control points. The document discusses the De Casteljau algorithm for geometric proof of Bézier equations, and limitations of Bézier curves where a change in one control point affects the global shape. It also mentions B-splines and OpenGL implementation of Bézier curves using evaluators.
Solid modeling
This document discusses different techniques for representing 3D solid objects in computer modeling, including boundary representation (B-rep), constructive solid geometry (CSG), and spatial partitioning. B-rep describes objects by their surface boundaries like vertices and faces. CSG uses Boolean operations on primitives. Spatial partitioning divides space into uniform cells. Each technique has strengths and weaknesses in terms of accuracy, domain of representable objects, uniqueness of representation, and efficiency.
CS 354 Bezier Curves
The document discusses Bézier curves and provides information about a CS 354 class. It includes details about an in-class quiz, the professor's office hours, and an upcoming lecture on Bézier curves and Project 2, which is due on Friday. The lecture will cover procedural generation of a torus from a 2D grid, GLSL functions needed for the project, normal maps, coordinate spaces, interpolation curves, and Bézier curves.
Geometric modeling111431635 geometric-modeling-glad (1)
This document discusses different types of geometric modeling methods including wireframe, surface, and solid modeling. Wireframe modeling uses points and lines to define objects but does not represent actual surfaces or volumes. Surface modeling defines the outer surfaces of an object. Solid modeling precisely defines the enclosed volume of an object using its faces, edges, and vertices. Constructive solid geometry and boundary representation are two common solid modeling techniques. CSG uses Boolean operations to combine primitive shapes, while boundary representation stores topological information about faces, edges, and vertices. Feature-based modeling allows shapes to be created through operations like extruding, revolving, sweeping, and filling.

Thin pressure vessels experience two main stresses: hoop or circumferential stress, which resists bursting from internal pressure, and longitudinal stress from changes in vessel length or volume. Hoop stress in a thin cylinder can be calculated by considering the equilibrium of half the cylinder, where the total force from internal pressure equals the total resisting force from the hoop stress in the cylinder walls. Longitudinal stress is caused by any change in the vessel's length or volume when under pressure.

An improved modulation technique suitable for a three level flying capacitor ...
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.
