Extrusion is the process by which a block/billet of metal is reduced in cross section by forcing it to flow through a die orifice under high pressure. • In general‚ extrusion is used to produce cylindrical bars or hollow tubes or for the starting stock for drawn rod‚ cold extrusion or forged products. • Most metals are hot extruded due to large amount of forces required in extrusion. Complex shape can be extruded from the more readily extrudable metals such as aluminium. * The products obtained are also

Fibonacci sequence in arithmetic sequence The Fibonacci sequence is a series of numbers in which each number is the sum of the previous two. It starts with 0 and 1‚ which equals 1. Then 1 plus 2 equals 3‚ 2 plus 3 equals 5‚ and so on. n mathematical terms‚ the sequence Fn of Fibonacci numbers is defined by the recurrence relation With seed values[1] The Fibonacci numbers are represented practically everywhere.

Case Study Finance - EDHEC MBAUnited Metal | | Background We refer to the case in the finance textbook for the details. Throughout our efforts in determining the right decision for United Metal‚ our team decided to calculate the difference between the ‘Make’ or ‘Buy’ options‚ using the numbers given in the case. However‚ in order to determine the net present value (NPV) and make appropriate recommendations‚ a risk adjusted discount rate (rate-of-return or ‘r’) needs to be incorporated.

GOFFMAN‚ SCHEFF AND SCASZ ARGUE THAT MENTAL ILLNESS IS A SOCIAL CONSTRCUTION. Mental illness is a general term referring to psychological‚ emotional‚ or behavioural disorders as well to the view that these disorders are diseases of the mind. Because it’s more to do with the psychological aspect‚ methods of treatment are different from a physical disability. A physical disability may involve treatment like acupuncture and traditional medicine whilst a mental illness (disability) treatment involves

[pic] Fourier Series: Basic Results [pic] Recall that the mathematical expression [pic] is called a Fourier series. Since this expression deals with convergence‚ we start by defining a similar expression when the sum is finite. Definition. A Fourier polynomial is an expression of the form [pic] which may rewritten as [pic] The constants a0‚ ai and bi‚ [pic]‚ are called the coefficients of Fn(x). The Fourier polynomials are [pic]-periodic functions. Using the trigonometric
