Dissolution of cellulose with ionic liquids allows the comprehensive utilization of cellulose by
combining two major green chemistry principles: using environmentally preferable solvents …

The design of strapdown inertial navigation system (INS) algorithms based on dual
quaternions is addressed. Dual quaternion is a most concise and efficient mathematical tool to …

The in-flight alignment is a critical stage for airborne inertial navigation system/Global
Positioning System (INS/GPS) applications. The alignment task is usually carried out by the …

Alignment of the strapdown inertial navigation system (INS) has strong nonlinearity, even
worse when maneuvers, eg, tumbling techniques, are employed to improve the alignment. …

This paper proposes a numerical-integration perspective on the Gaussian filters. A Gaussian
filter is approximation of the Bayesian inference with the Gaussian posterior probability …

Observability is an important aspect of the state-estimation problem in the integration of the
inertial navigation system (INS) and the Global Positioning System (GPS) as it determines the …

Inertial navigation system (INS) necessitates an alignment stage to determine the initial attitude
at the very start. A novel alignment approach is devised by way of an optimization method…

Inertial navigation and attitude initialization in polar areas become a hot topic in recent years
in the navigation community, as the widely-used navigation mechanization of the local level …

Combination pretreatment of rice straw using microwave and alkali and its enzymic hydrolysis
were investigated and compared with the alkali-alone pretreated process. First, the effect …

Magnetometer and inertial sensors are widely used for orientation estimation. Magnetometer
usage is often troublesome, as it is prone to be interfered by onboard or ambient magnetic …
