Toward learning autonomous pallets by using fuzzy rules, applied in a Conwip system
(Journal article; Peer reviewed, 2012)Nowadays, material planning and control strategies are becoming continuously complex tasks spanning from individual plants to logistic networks. In fact, this is the consequence of increasing intricacy in product variants ... -
H-Infinity robust controller design for the synchronization of master-slave chaotic systems with disturbance input
(Journal article; Peer reviewed, 2012)This paper is concerned with the robust control problems for the synchronization of master-slave chaotic systems with disturbance input. By constructing a series of Lyapunov functions, novel H1 robust syn- chronization ... -
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 ... -
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 ... -
Pyrolytic formation of polycyclic aromatic hydrocarbons from sesquiterpenes
(Journal article; Peer reviewed, 2012)The products of the pyrolysis of four sesquiterpenes, β-caryophyllene, α-cedrene, longifolene and valencene, have been examined. Pyrolysis was carried out at 300, 400 and 500 °C, the products determined by GC–MS and then ... -
Observer-Based Stabilization of Stochastic Systems with Limited Communication
(Journal article; Peer reviewed, 2012)This paper studies the problem of observer-based stabilization of stochastic nonlinear systems with limited communication. A communication channel exists between the output of the plant and the input of the dynamic ... -
The use of lightweight expanded clay aggregate (LECA) as sorbent for PAHs removal from water
(Journal article; Peer reviewed, 2012)Lightweight expanded clay aggregate (LECA) has been explored as a sorbent for the removal of PAHs (phenanthrene, fluoranthene and pyrene) from water. The efficacy of LECA as a sorbent for PAHs was assessed using contact ... -
The Unbalanced Linguistic Aggregation Operator in Group Decision Making
(Journal article; Peer reviewed, 2012)Many linguistic aggregation methods have been proposed and applied in the linguistic decision- making problems. In practice, experts need to assess a number of values in a side of reference domain higher than in the other ... -
Consistency of probability decision rules and its inference in probability decision table
(Journal article; Peer reviewed, 2012)In most synthesis evaluation systems and decision-making systems, data are represented by objects and attributes of objectswith a degree of belief. Formally, these data can be abstracted by the form objects; attributes; ... -
Waste heat recovery from a marine waste incinerator using a thermoelectric generator
(Journal article; Peer reviewed, 2012)A marine waste incinerator has been evaluated for waste heat harvesting using thermoelectric generators (TEG). The application has been evaluated using mathematical modeling to optimize the heat exchanger and some vital ... -
Enhanced chain dynamics in loop-sorting-systems by means of layout optimization and a kinematic model of the polygon action
(Journal article; Peer reviewed, 2012)Poor dynamics owing to polygon action is a known concern in mechanical applications of closed articulated chains. In this paper a kinematic model of the polygon action in large chains of loop-sorting-systems is proposed. ... -
Hardware-in-the-loop implementation for an active heave compensated drawworks
(Journal article; Peer reviewed, 2011)This paper presents the setup and running of a hardware-in-loop (HIL) simulation for an active heave compensated (AHC) draw-works. A simulation model of the draw-works is executed on a PC to simulate the AHC draw-works ... -
Reducing whole-body vibration exposure in backhoe loaders by education of operators
(Journal article; Peer reviewed, 2012)Whole-body vibration is a health hazard for operators of construction machinery. The level of whole-body vibration exposure on the operator is governed by three different factors; performance of the suspension system of ... -
Semiactive control methodologies for suspension control with magnetorheological dampers
(Journal article; Peer reviewed, 2012)Suspension systems are one of the most critical components of transportation vehicles. They are designed to provide comfort to the passengers to protect the chassis and the freight. Suspension systems are normally provided ... -
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 ... -
