Optimization of Machining Parameters in Turning Operation Using PSO and AIS Algorithms: A Survey

In recent manufacturing, the optimization of turning processes is one of important problems which aim to increase competitiveness and product quality. However, the choice of optimal machining parameters is difficult and complex. Traditionally, the selections is heavily relies on trial and error methods which is tedious and unreliable. Metaheuristics methods have been proposed over the last decade to overcome these problems. This paper presents a survey for optimizing the parameters of turning operation using Particle Swarm Optimization (PSO) and Artificial Immune System (AIS). This study deals with different machining performance in turning operation like surface roughness, material removal rate , tool wear , tool life, production cost, machining time and cutting temperature. Most papers in the field of turning parameters optimization are based on (PSO) algorithms, but only a few efforts that are using (AIS) algorithms. In addition, there is a gap of several machining operation parameters especially for cutting temperature optimization in turning operation using PSO and AIS

Kansei for the Digital Era

For over 40 years, Kansei-based research and development have been conducted in Japan and other East Asian countries and these decades of research have influenced Kansei interpretation. New methods and applications, including virtual reality and artificial intelligence, have emerged since the millennium, as the Kansei concept has spread throughout Europe and the rest of the world. This paper reviews past literature and industrial experience, offering a comprehensive understanding of Kansei, the underlying philosophy, and the methodology of Kansei Engineering from the approach of psychology and physiology, both qualitatively and quantitatively. The breadth of Kansei is described by examples, emerging from both industry and academia. Additionally, thematic mapping of the state-of-the-art as well as an outlook are derived from feedback obtained from structured interview of thirty-five of the most distinguished researchers in Kansei. The mapping provides insights into current trends and future directions. Kansei is unique because it includes the consideration of emotion in the design of products and services. The paper aims at becoming a reference for researchers, practitioners, and stakeholders across borders and cultures, looking for holistic perspectives on Kansei, Kansei Engineering, and implementation methods. The novelty of the paper resides in the unification of authors amongst pioneers from different parts of the world, spanning across diversified academic backgrounds, knowledge areas and industries

Bitter cold, sharp cheese and loud colours : the chromatic cacophony of cross-modal sensory perception

This thesis addresses the question of how a consumer's different sensory modalities interact to guide perception and decision-making. Specifically, in three studies, its primary objective is to investigate the cross-modal link between vision (colour) and touch. Colour has a profound influence on human perception. Not only does it cause changes in physiological or emotional states, it can shape what is perceived in other sensory modalities. However, the body of research on these “cross-modal” experiences has predominantly examined colour’s influence on taste and smell. Instead, Study 1 sets out to identify the cross-modal association between vision (colour) and touch (perceived texture of food). Results from Study 1 show colour influences 'perceived' texture of the food during consumption. The extant literature on cross-modal associations involving colour are heavily skewed to situation involving food consumption. To extend existing knowledge, Study 2 applies these cross-modal effects between vision and touch to an advertising setting, where colour is found to influence 'expected' texture. Finally, Study 3 examines the multidirectional nature of the colour-touch relationship, specifically whether touching a product influences perception relating to product colour. Findings from Study 3 demonstrate, under certain conditions, touch does have a cross-modal influence that shapes affective responses to colour cues. Together, the three studies provide further understanding of the cross-modal relationship between vision and touch, and demonstrate the existence of the cross-modal effect in different scenarios and with different products.

Evaluation of constructs to integrate a legislative code of ethics in México

Legislators, as public officials, have generated mistrust among citizens because of their behavior, but fundamentally because of their legislative labor. The absence of norm to guide the legislators has caused México to become one of the countries that still has not developed a code of ethics. Given this situation, the objective of this research is to identify the relation and significance among variables individually and in relation to each other. These variables measure the significance and impact within a Code of Ethics. The variables were substantiated through a theoretical framework. For that reason, in the first part of this research each variable is based on a particular framework. The variables for this research are professionalization, accountability, omission, and decision making. Later come the methodological description, analysis and bibliography
