On the Distribution of the Sum of n Non-Identically Distributed Uniform Random Variables

The distribution of the sum of independent identically distributed uniform random variables is well-known. However, it is sometimes necessary to analyze data which have been drawn from different uniform distributions. By inverting the characteristic function, we derive explicit formulae for the distribution of the sum of n non-identically distributed uniform random variables in both the continuous and the discrete case. The results, though involved, have a certain elegance. As examples, we derive from our general formulae some special cases which have appeared in the literature.Comment: 20 page

DESIGN, ANALYSIS AND FABRICATION OF CANARD WING CONFIGURATION

In aeronautics, canard is an airframe configuration of fixed wing aircraft in which the forward surface is smaller than the rearward, the former being known as the "canard", the aim of this project is to design, analysis and fabricate of the canard wing configuration. The first step in our project we do design of the canard wing configuration and analysis the aerofoil we do take in the design and conduct the 2D flow analysis by putting the canard aerofoil followed by main wing aerofoil by means the flow pattern how seriously affect the main wing. Then we fabricate the canard configuration by placing the canard in the best place that does not affect the main wing flow parameter. A canard design tends to be less controllable than a conventional design because aileron on the main wing may be subject to turbulence from the canards that varies widely at different angle of attack leading to conditions of deep stall. If the ailerons were located on the canards, we used to find the best place where the canard aero foil suits well and it does affect the main wing flow parameter in the cruise speed at high angle attack. Canards have poor stealth characteristics because they present large, angular surfaces that tend to reflect radar signals
