Abstract

Purpose

In the post-capture stage, the tumbling target rotates the combined spacecraft system, and the detumbling operation performed by the space robot is required. To save the costly onboard fuel of the space robot, this paper aims to present a novel post-capture detumbling strategy.

Design/methodology/approach

Actuated by the joint rotations of the manipulator, the combined system is driven from three-axis tumbling state to uniaxial rotation about its maximum principal axis. Only unidirectional thrust perpendicular to the axis is needed to slow down the uniaxial rotation, thus saving the thruster fuel. The optimization problem of the collision-free detumbling trajectory of the space robot is described, and it is optimized by the particle swarm optimization algorithm.

Findings

The numerical simulation results show that along the trajectory planned by the detumbling strategy, the maneuver of the manipulator can precisely drive the combined system to rotate around its maximum principal axis, and the final kinetic energy of the combined system is smaller than the initial. The unidirectional thrust and the lower kinetic energy can ensure the fuel-saving in the subsequent detumbling stage.

Originality/value

This paper presents a post-capture detumbling strategy to drive the combined system from three-axis tumbling state to uniaxial rotation about its maximum principal axis by redistributing the angular momentum of the parts of the combined system. The strategy reduces the thrust torque for detumbling to effectively save the thruster fuel.

Case overview/synopsis

Situated at Tito’s Lane in North Goa, Tito’s was the discotheque founded by Tito Henry D’Souza in 1971. The company offered restaurant, concert space and nightclub services to music and party lovers from diverse locations. Ricardo D’Souza and David D’Souza (both brothers) spearheaded the business. Ricardo understood the growth of markets and the factors driving the growth in India. The key factors driving the Tito’s and pub, bar, café and lounge business in India were rising disposable incomes among Indians, nightlife parties by young individuals and preference for quality food and alcoholic beverages among the customers. By seeing the opportunities in 2022, Ricardo considered expanding its business across India. How should Ricardo move to expand its business and offerings? What strategies should they devise for the growth of the business?

Abstract

Purpose

Food not only satisfies the need and nourishes positive experiences but also enhances involvement with the cultural, social and environmental attributes of a destination. As urban tourism is embracing sustainable consumption practices (SCP), this study aims to explore tourist’s responsible behaviour by embracing traditional gastronomic delicacies. More specifically, it pinpoints the driving forces behind why people choose traditional gastronomic delights.

Design/methodology/approach

The study adopted the triangulation method involving the grounded theory approach (GTA) attained through a series of focus group discussions followed by the survey method taking an emerging economy’s perspective (India and Bangladesh). This study accords equal importance to both the demand and supply perspectives of gastronomic tourism and its stakeholders.

Findings

Critical dimensions such as travel motivation, tourist expectations, socio-economic perspectives, mindful consumption, sustainable marketing efforts and community awareness were identified as major influencers towards traditional gastronomic delicacies.

Practical implications

The present study bears significance to the urban developers, policymakers, marketers, regional tourism bodies and tour operators in promoting urban gastronomic cultures through marketing traditional delicacies for sustainable development of the evolving gastronomic industry in India and Bangladesh.

Originality/value

This study makes a novel attempt in exploring critical dimensions in an evolving gastronomic industry by blending an innovative qualitative research methodology like GTA supported by the empirical validation process (quantitative). It proposes a theoretical framework for further advancement of gastronomic and urban tourism towards a SCP.

Abstract

Purpose

This study aims to explore the evolutionary trajectory of American corporations and their governance over the past few centuries, using a multidisciplinary investigative approach. The research focuses on the American business landscape because it has played a pivotal role in shaping the field of corporate governance theory and practice.

Design/methodology/approach

The author thoroughly investigates archival records, legal documents, academic publications, reputable databases and pertinent literature to unearth valuable insights into the key events that have influenced the evolutionary path of American corporations and their governance throughout history.

Findings

Delving into the evolutionary journey of American corporations and their governance reveals a multifaceted narrative, enhancing our comprehension of the impact of the external socio-economic environment, and the effectiveness and limitations of established corporate governance paradigms in addressing such transformations. This introspection establishes the groundwork for ongoing discussions concerning how corporate governance should adapt to meet the evolving needs and expectations of stakeholders and society as a whole, with a specific focus on the pivotal role that boardrooms could play in this regard.

Practical implications

The insights gained from this analysis offer practitioners a foundational resource to understand corporate governance in a complex business landscape. Armed with this understanding, practitioners can better align governance strategies with both historical context and contemporary requirements.

Social implications

The research has significant social implications in the sense that history highlights the importance of the society in influencing corporate governance practices. It specifically emphasizes the need for the board of directors to consider both shareholder value and social responsibility, while also fostering public trust and confidence.

Originality/value

Many corporate governance concepts are often used with limited understanding of their initial intent, resulting in their unquestioned adoption. In this paper, the author offers a contextual exploration of historical events that have contributed to the development of these diverse corporate perspectives. To the best of the author’s knowledge, there are exceedingly few, if any, papers that present comparably insightful and multidisciplinary insights into the evolutionary path of corporations and their governance, especially within a dynamic and influential market like that of the USA.

Abstract

Purpose

The purpose of this paper is to obtain values that stabilize the lateral and longitudinal flight of the quadrotor for which the morphing amount and the best Proportional-Integral-Derivative (PID) coefficients are determined by using the simultaneous perturbation stochastic approximation (SPSA) optimization algorithm.

Design/methodology/approach

Quadrotor consists of body and arms; there are propellers at the ends of the arms to take off and rotors that rotate them. By reducing the angle between mechanism 1 and the rotors with the horizontal plane, the angle between mechanism 2 and the arms, the rotors rise and different configurations are obtained. Conventional multi-rotor aircraft has a fixed fuselage and does not need a tail rotor to change course as helicopters do. The translational and rotational movements are provided by the rotation of the rotors of the aircraft at different speeds by creating moments about the geometric center in 6-degree-of-freedom (DOF) space. These commands sent from the ground are provided by the flight control board in the aircraft. The longitudinal and lateral flight stability and properties of different configurations evaluated by dynamic analysis and simulations in 6 DOF spaces are investigated. An algorithm and PID controller are being developed using SPSA to achieve in-flight position and attitude control of an active deformable aircraft. The results are compared with the results of the literature review and the results of the previous article.

Findings

With SPSA, the best PID coefficients were obtained in case of morphing.

Research limitations/implications

The effects of quadrotor arm height and hub angle changes affect flight stability. With the SPSA optimization method presented in this study, the attitude is quickly stabilized.

Practical implications

With the optimization method, the most suitable PID coefficients and angle values for the lateral and longitudinal flight stability of the quadrotor are obtained.

Social implications

The transition rate and PID coefficients are determined by using the optimization method, which is advantageous in terms of cost and practicality.

Originality/value

With the proposed method, the aircraft can change shape to adapt to different environments, and the parameters required for more stable flight for each situation will be calculated, and this will be obtained more quickly and safely with the SPSA optimization method.
