Abstract A single-cylinder engine is a basic piston engine configuration of an internal combustion engine. It is often seen on motorcycles, auto rickshaws, motor scooters, mopeds, dirt bikes, go-karts, radio-controlled models, and has many uses in portable tools…

Introduction What millennial-old technique is the basics of many of the most innovative technical breakthroughs of this moment? Robotics, 3D printing and new means of transport all have one thing in common: often they are driven by a planetary gearbox. What is planetary gearbox? A planetary gearbox is a gearbox with the…

Introduction The Geneva drive or Maltese cross is a gear mechanism that translates a continuous rotation movement into intermittent rotary motion. The rotating drive wheel is usually equipped with a pin that reaches into a slot located in the other wheel (driven…

1. What does popt and pcov mean? Ans: POPT is The output is an array with the values for the parameters used above so that the sum of the squared residuals of data is minimized. PCOV is used to calculate the the standard deviation errors of popt. 2. What does np.array(temperature) do? Ans: It stores the values of temperature…

Introduction In numerical analysis, Newton\'s method (also known as the Newton–Raphson method), named after Isaac Newton and Joseph Raphson, is a method for finding successively better approximations to the roots (or zeroes) of a real-valued function. It is one example of a root-finding algorithm. In this…

Introduction Centrifugal pumps are the most common type of pump used in industry, agriculture, municipal (water and wastewater plants), power generation plants, petroleum and many other industries. Centrifugal pumps are the primary pump type in the class of pumps called \"kinetic\" pumps and are distinctly different…

Introduction An air flow bench is a device used for testing the internal aerodynamic qualities of an engine component and is related to the more familiar wind tunnel. It is used primarily for testing the intake and exhaust ports of cylinder heads of internal combustion…

INTRODUCTION Transient flow The flow of a fluid is transient or unsteady if its flow parameters (i.e. velocity and pressure) are dependent not only on the position in the coordinate system used to describe the field of flow, but also on time. A distinction is made between three different types…

Introduction An airfoil is the term used to describe the cross-sectional shape of an object that, when moved through a fluid such as air, creates an aerodynamic force. Aerofoils are employed on aircraft as wings to produce lift or as propeller blades to produce thrust. Both these forces are produce perpendicular to the…

Introduction Pipe flow, a branch of hydraulics and fluid mechanics, is a type of liquid flow within a closed conduit (conduit in the sense of a means of containment). The other type of flow within a conduit is open channel flow. These two types of flow are similar in many ways, but differ in one important aspect. Pipe…

NASA Glenn computer program CEA (Chemical Equilibrium with Applications) produces a library of thermodynamic datas. This library, containing data for over 2000 solid, liquid, and gaseous chemical species for temperatures ranging from 200 to 20 000 K, is available for use with other computer codes as well. The data are…

Genetic algorithms (GAs) are search methods based on principles of natural selection and genetics.GAs encode the decision variables of a search problem into finite-length strings of alphabets of certain cardinality. The strings which are candidate solutions to the search problem are referred to as chromosomes, the alphabets are…
