Robust observer design for Takagi-Sugeno fuzzy systems with mixed neutral and discrete delays and unknown inputs
(Journal article; Peer reviewed, 2012)A robust observer design is proposed for Takagi-Sugeno fuzzy neutral models with unknown inputs. The model consists of a mixed neutral and discrete delay, and the disturbances are imposed on both state and output signals. ... -
Effect of heat on the adsorption properties of silica gel
(Journal article; Peer reviewed, 2012)Adsorption properties of silica gel have been attributed to the surface hydroxyl groups of silica gel. Some hydroxyl groups are free standing and called free silanol groups. Some are hydrogen bonded to neighbouring silanol ... -
Fuzzy variable structure control for uncertain systems with disturbance
(Journal article; Peer reviewed, 2012)This paper focuses on the fuzzy variable structure control for uncertain systems with disturbance. Specifically, the fuzzy control is introduced to estimate the control disturbance, the switching control is included to ... -
The harp: a vehicle crash test apparatus for full-scale crash test experiments
(Journal article; Peer reviewed, 2012)The current paper describes an apparatus for full-scale vehicle crash test experimentation. This apparatus is referred to as the harp. In brief, the harp may either accelerate a trolley which is impacted into a test vehicle ... -
Catalytic oxidation and reduction of polycyclic aromatic hydrocarbons (PAHs) present as mixtures in hydrothermal media
(Journal article; Peer reviewed, 2012)The reactivity of fluorene, anthracene, and fluoranthene under oxidation and reduction conditions were investigated in this study. This project looks at catalytic and green approaches of converting PAHs to less toxic and/or ... -

A sliding mode approach to H∞ synchronization of masterslave time-delay systems with Markovian jumping parameters and nonlinear uncertainties
(Journal article; Peer reviewed, 2012)In this paper, a sliding-mode approach is proposed for exponential H∞ synchronization problem of a class of masterslave time-delay systems with both discrete and distributed time-delays, norm-bounded nonlinear uncertainties ... -
H∞ fuzzy control of DC-DC converters with input constraint
(Journal article; Peer reviewed, 2012)This paper proposes a method for designing H∞ fuzzy control of DC-DC converters under actuator saturation. Because linear control design methods do not take into account the nonlinearity of the system, a T-S fuzzy model ... -
Entry-item-quantity-ABC analysis-based multitype cigarette fast sorting system
(Journal article; Peer reviewed, 2012)Numerous items, small order, and frequent delivery are the characteristics of many distribution centers. Such characteristics generally increase the operating costs of the distribution center. To remedy this problem, this ... -
Approximate analytic and numerical solutions to Lane-Emden equation via fuzzy modeling method
