Abstract: Launching satellites and maintaining a mission while in orbit is a procedural and expensive activity. It is therefore imperative; satellite operations are designed to suit mission requirements so that operational activities are planned and managed properly. The earth station design and mission control planning are con-currently conducted with satellite payload and platform design and development. This strategy will ensure adequate testing of both satellite and ground facilities prior launching into the desired orbit. In this paper, Nigeriasat-2 ground segment management experiences and other contemporary satellite ground operations principles are reviewed. The challenges and variations among different satellite category are discussed. The paper provide a comprehensive requirements needs for successful ground station management operations including human requirements and satisfactory layout structure based on practical experiences for an effective mission operation.

Abstract: With the constant and increase growth in technological advancements, technical know-how and innovations, keeping up with the trends becomes the order of the day, most technological advancement aim at further improving our way of life and/or providing new and easier ways to solve a general problem, with so many examples to site, like the invention of smart home security systems, smart baby monitors, self-driven cars, digital voting systems etc, wireless power transfer seems to be at the very top of this list. The main objective of wireless power transfer is to eliminate damage of mobile phone USB port and make the transfer of power from sources to devices more convenient and seamless.  Wireless charging of gadgets is one of the new emerging technologies in the world at the moment. The most common method used at the moment is wireless power transfer by inductive coupling. Wireless power transfer is one of the simplest and cheapest ways of charging as it eliminates the use of conventional copper cables and current carrying wires. The research methodology and principle of operation are devised for wireless power transfer through inductive coupling, and a feasible design is modeled accordingly. The inductive coupling technique is used since currently it’s the easiest method of wireless power transfer because of high efficiency and large amount of the energy transferred. In this project report, results of experiments done to check wireless power transfer will be discussed. Also, to further show its versatility and range of applications the power transferred will be used to charge small and medium devices with emphasis on mobile phones with the aid of additional circuitry; and also study the effect of placing hurdles between the transmitter and receiver so as to establish if it is an alternative in the medical industry for charging pace makers.

Abstract: In this paper, based on Jumarie type of Riemann-Liouville (R-L) fractional calculus and a new multiplication of fractional analytic functions, we obtain a fractional integral formula involving fractional exponential function. Moreover, we provide some examples to illustrate our result. In fact, our formula is a generalization of traditional calculus formula.
