The document summarizes key aspects of hydrographic surveys. It discusses controlling horizontal and vertical positions, measuring depths through sounding, and producing charts. Soundings are taken using various instruments and referenced to tidal datums. Depths are plotted on charts along with shorelines, depth contours, and navigational features. Hydrographic surveys provide critical data for safe navigation and engineering projects.

This document discusses finding the angle of inclination and slope of a line, as well as the angle between two lines. It defines inclination as the angle measured counterclockwise from the x-axis to the line. Slope is related to inclination by the formula that if a non-vertical line has an inclination of θ and a slope of m, then tanθ = m. It also provides the formula for finding the angle between two non-perpendicular lines based on their slopes. Several examples are worked through to demonstrate finding inclination, slope, and the angle between lines.

A really simple presentation about Stereo Vision, especially the stereo vision in real time applied to mobile robotics. In the talk I explained how the stereo vision works, I presented a simplified mathematical model to achieve it and I proposed what for me is the best hardware to use to achieve real-time stereo vision, that is, the sensor ZED produced by Stereolabs used together with the board Jetson TX1 by Nvidia. The presentation is really simple and has been made for an audience with limited knowledge about computer vision and the underhood mathematics. The talk was held during the event "Officine Robotiche 2016" in Rome, 21-22 May 2016

Stereo vision

Farah M. Altufaili

Two cameras displaced horizontally from one another can obtain two differing views of a scene, similar to human binocular vision. By comparing these two images and examining the relative positions of objects, 3D information like depth can be extracted from the 2D images. This process is called stereo vision. The depth information is contained in pixel displacements between the two images called disparities, which are inversely proportional to distance. Knowing camera intrinsics and their relative pose allows reconstructing 3D point positions through triangulating corresponding image points. Reconstruction accuracy depends on factors like disparity, baseline distance, and focal length.

The document discusses the slope (gradient) of a line and how to calculate it. It provides four methods to calculate slope: (1) The rise over the run between two points (vertical change over horizontal change) (2) The change in y-values over the change in x-values between two points using a formula (3) The slope of a line is equal to the tangent of the angle of inclination (4) The relationship between slopes of parallel and perpendicular lines. Two lines are parallel if their slopes are equal, and perpendicular if the product of their slopes is -1. An example problem demonstrates finding the value of a that results in two lines being parallel or perpendicular.

It begins with quadrilateral as the parent shape and branches down to more specific shapes such as squares, rectangles, rhombi, parallelograms, trapezoids, and kites. The text explains that quadrilaterals can be classified based on their properties, and moving down the hierarchy, the shapes become more specialized. It also notes that any property of the parent shapes also applies to the child shapes.

Additionally, it defines different types of triangles such as isosceles and equilateral triangles based on their side lengths and angle measures.

The document discusses division of intervals in coordinate geometry. It states that for a 2 unit math exam, interval division questions are restricted to finding the midpoint, which divides an interval in a 1:1 ratio. For Extension 1 exams, intervals can be divided in any ratio internally or externally.

All straight lines can be written in the form of y = mx + b, where m is the slope and b is the y-intercept. Alternatively, lines can be written in the general form of Ax + By + C = 0, where A, B, and C are integers or surds. Lines parallel to the x-axis have the form y = c, where c is a constant. Lines parallel to the y-axis have the form x = k, where k is a constant. The example shows finding the equation of a line perpendicular to another line in general form.

The document discusses different methods for calculating the area under a curve or between curves. (1) The area below the x-axis is given by the integral of the function between the bounds, which can be positive or negative depending on whether the area is above or below the x-axis. (2) To calculate the area on the y-axis, the function is solved for x in terms of y, then the bounds are substituted into the integral of this new function with respect to y. (3) The area between two curves is calculated by taking the integral of the upper curve minus the integral of the lower curve, both between the same bounds on the x-axis.

The document discusses different methods for calculating the area under a curve or between curves. (1) The area below the x-axis is given by the integral of the function between the bounds, which can be positive or negative depending on whether the area is above or below the x-axis. (2) To calculate the area on the y-axis, the function is solved for x in terms of y, then the bounds are substituted into the integral of this new function with respect to y. (3) The area between two curves is calculated by taking the integral of the upper curve minus the integral of the lower curve, both between the same bounds on the x-axis.

11 x1 t16 01 area under curve (2013)

0 The document discusses the relationship between integration and calculating the area under a curve. It shows that the area under a curve from x=a to x=b can be calculated as the integral from a to b of the function f(x) dx. This is equal to the antiderivative F(x) evaluated from b to a. The area under a curve can also be estimated using rectangles, and as the width of the rectangles approaches 0, the estimate becomes the exact area. The derivative of the area function A(x) gives the equation of the curve f(x). Examples are given to calculate the exact area under curves.

A summation is the sum of terms in a sequence. There are four special summations that were presented: the sum of the first n natural numbers, the sum of the first n integers, the sum of the squares of the first n integers, and the sum of the cubes of the first n integers. Riemann sums are used to approximate the area under a curve between two values by dividing the interval into subintervals and creating rectangles to estimate the area, with the true area found as the number of subintervals approaches infinity. An example of using a Riemann sum to calculate the distance traveled given the velocity function over time between two points was provided.

The document provides information on index laws and the meaning of indices in algebra: - Index laws state that am × an = am+n, am ÷ an = am-n, and (am)n = amn. Exponents can be added or subtracted when multiplying or dividing terms with the same base. - Positive exponents indicate a term is raised to a power. Negative exponents indicate a root is being taken. Terms with exponents are evaluated from left to right. - Examples demonstrate how to simplify expressions using index laws and interpret different types of indices.

The document describes the Trapezoidal Rule for approximating the area under a curve between two points. It shows that the area A is estimated by dividing the region into trapezoids with height equal to the function values at the interval endpoints and bases equal to the intervals. In general, the area is approximated as the sum of the areas of each trapezoid, which is equal to the average of the endpoint function values multiplied by the interval length.

The document discusses nth roots of unity. It states that the solutions to equations of the form zn = ±1 are the nth roots of unity. These solutions form a regular n-sided polygon with vertices on the unit circle when placed on an Argand diagram. As an example, it shows that the solutions to z5 = 1 are the fifth roots of unity located at angles that are integer multiples of 2π/5 around the unit circle. It then proves that if ω is a root of z5 - 1 = 0, then ω2, ω3, ω4 and ω5 are also roots. Finally, it proves that 1 + ω + ω2 + ω3 + ω4 = 0.
