Understanding the Relationship Between Perceived Quality Cues and Quality Attributes in the Purchase of Meat in Malaysia

This study utilizes the Total Food Quality Model to gain a better understanding of how Malaysian consumers make their decision to purchase fresh/chilled meat. We examine the association between quality cues and desired values (quality attributes) with regard to food that is guaranteed Halal, safe to eat, healthy and nutritious, has a good taste, represents good value for money, and is produced in a way that protects the environment and worker welfare. The findings reveal that different quality cues assume different levels of importance when pursuing different desired values

Variable speed control of two-mass wind turbine with unknown stiffness

This paper presents a variable speed control of two-mass wind turbine with unknown stiffness. The aim of the algorithm is to control rotor speed in order to maintain optimum tip-speed ratio and obtain maximum power output of the turbine with the appearance of unknown stiffness. The algorithm is formulated using full-state feedback which stabilizes in the sense of Lyapunov. Adaptation law is embedded into the variable speed algorithm to assure adaptability towards unknown stiffness. To validate the effectiveness of proposed speed control, a simulation in MATLAB/SIMULINK® is carried out. The results show that optimum tip speed ratio is obtained via the proposed controlled rotor speed regardless

Towards a Data Classification Model for Circular Product Life Cycle Management

Nowadays, due to the limited availability of resources, the adoption of sustainable practices is gaining importance, especially while dealing with the manufacturing sector that is considered one of the most resource greedy sectors. To cope with this issue, a new sustainable and industrial economy, called “circular economy” arisen. The diffusion of this economy can be eased by the advance management of data and information. Nevertheless, from the extant literature emerged some criticalities regarding information management flows while dealing with circular economy strategies adoption. Indeed, the present work aims to first identify the main criticalities in information management while adopting circular economy principles, and second to investigate the decisions, and the related data and information required to make these decisions, that manufacturers have to undertake to enable the circular product life cycle management. To achieve this goal, the present work relies on the scientific literature. This choice enables to grasp the widespread knowledge developed by scholars about these concepts, by individualizing the main decisions that should be taken by the company internal stakeholders, to manage circular products, being affected by external stakeholders’ behaviours and decisions along product life cycle. Therefore, this work aims to support circular product life cycles management and, this objective has been achieved through the development of a data classification model
