Although the capacity is often used as a criterion to evaluate the state of health (SOH) of a lithium-ion battery, it cannot be measured on-line. Besides, degradation modeling only depending on historical capacity data will cause a large prediction error in the long term. Actually, some parameters can be monitored, such as the duration of equal discharging voltage difference, the interval of equal...
Nowadays, complex hybrid systems, whose behavior combines continuous and discrete event dynamics, are applied in many engineering applications, from electrical circuits to aircraft systems. However, diagnosis of hybrid system, which is composed of components involving multiple modes, demands unfordable computation due to high complexity and its exponential behaviors caused by combinational explosion...
The online estimation of fuel property parameters (density and bulk modulus) for use in automotive engine control is considered. The estimation is carried out through state augmentation (including the parameters in the state vector) and use of an Unscented Kalman Filter (UKF) that is based on a physical model of the common rail fuel injection system. As it is known that state augmentation usually...
Automatic word-segmentation is vital for the reading, comprehension and translation of classics. However, large amount of special terms, allusions and proper names within the classics make it difficult for word segmentation. Taking classics of tea as the subject of research, a method was proposed using likelihood ratio statistics to decide two-character words candidate, three character words candidates...
