Aiming at getting rid of the dependence of high precision external attitude reference, this paper presents a 18-position calibration algorithm. This method takes the accelerometer output as observation, adopting reasonable transposition arrangement to fully motivate the relation between the observation quantity and the inertial instrument error, using the least squares method complete identification...
Many works on preventive maintenance (PM) of systems only consider either a single failure mode, or statistically independent failure modes. Here, we study the maintenance policy for systems with two statistically dependent failure modes (namely maintainable, and nonmaintainable), and resource constraints. Assume (i) the nonmaintainable failures unidirectionally affect the maintainable failure rate;...
Accurate electricity demand forecasting is the foundation of power system operation and planning, the basic of placing development plans, business strategy and tactics of the power companies. Electricity consumption is a gray system which is impacted by economic development, industrial structure, income levels and national policies. The paper counted Inner Mongolia electricity data from four factors,...
The memristor, known as the fourth basic two-terminal circuit element, has attracted many research interests since the first real device was developed by HP labs in 2008. The nano-scale memristive device has the potential to construct some novel computing systems because of its distinctive characters, such as non-volatility, non-linearity, low-power, and good scalability. These electrical characteristics...
