Forecast of Bharti Airtel Subscribers Economics I - Project GROUP 1 ABSTRACT Analysis of Bharti airtel’s subscriber base was done using Time series analytical tools to develop predictive models. Different models linear‚ exponential were developed and December 2009 forecast was made using them. Our research revealed that subscriber growth is non linear thus best explained and predicted by exponential curve such as logistic curve. Introduction

Solid state physics II Testing a Peltier Element Abstract The purpose of the experiment was to investigate the cooling properties of a Peltier element and specifically the relation between the electric current through the element and the temperature in a refrigerator cooled by the element. The “refrigerator” consisted of a cavity in a block of polystyrene foam with the Peltier element covering the opening of the cavity. A fan on top

Lemma states that for any two positive integers a and b‚ there exist unique integres q and r such that a = bq + r‚ where r must satisfy : (a) 1 < r < b (b) 0 < r < b (c) 0 < r < b (d) 0 < r < b Sol. (c) 0 < r < b 2. In the figure‚ the graph of a polynomial p(x) is shown. The number of zeroes of p(x) is : (a) 4 (b) 1 (c) 2 (d) 3 Sol. (b) Since the graph cuts the x-axis at only one point‚ hence p(x) has only one zero. 3. In the figure‚ if DE || BC‚ then x equals : (a) 6 cm (b) 8 cm (c) 10 cm (d)

surface being interpolated should be a variable dependent on location. The IDW interpolation technique was applied as it was found to be more accurate. Ali et al. [32] tested five wind speed interpolation methods (i.e. IDW‚ global polynomial interpolation‚ local polynomial interpolation‚ spline with 3 sub-types‚ and kriging with 4 sub-types) in Iraq. Based on the root mean square error values‚ the predicted values are compared with actual values for period between 1971 and 2010. The results demonstrated
