The impact of marketing on activities of Vietnam arts and cultural organizations

With the trend of budget reduction and autonomous operation of arts and cultural organizations, competition in this field to attract audiences is an inevitable trend. This sets out the requirements of marketing activities to bring arts to the audiences and bring the audience to arts, which is, to link arts with the audience; not only achieved the goal of establishing and meeting the audience needs, but also fulfilled the arts and cultural organizations’ task of creating arts. There have been many research perspectives on culture and arts marketing in the context of cultural integration and economic development associated with the characteristics of each country and region. In this study, the author approaches, inherits, and develops Rentschler's culture and arts marketing model to build a scale and conduct practical research in Hanoi, Vietnam. The survey subjects were identified as art practitioners (artists) with more than 3 years of working experience in 7 theaters in Hanoi. The research was carried out by qualitative method through secondary data collection, combined with the quantitative method through a survey of opinions of 200 artists.

Janus

Proximity detection is at the core of several mobile and ubiquitous computing applications. These include reactive use cases, e.g., alerting individuals of hazards or interaction opportunities, and others concerned only with logging proximity data, e.g., for offline analysis and modeling. Common approaches rely on Bluetooth Low Energy (BLE) or ultra-wideband (UWB) radios. Nevertheless, these strike opposite tradeoffs between the accuracy of distance estimates quantifying proximity and the energy efficiency affecting system lifetime, effectively forcing a choice between the two and ultimately constraining applicability. Janus reconciles these dimensions in a dual-radio protocol enabling accurate and energy-efficient proximity detection, where the energy-savvy BLE is exploited to discover devices and coordinate their distance measurements, acquired via the energy-hungry UWB. A model supports domain experts in configuring Janus for their use cases with predictable performance. The latency, reliability, and accuracy of Janus are evaluated experimentally, including realistic scenarios endowed with the mm-level ground truth provided by a motion capture system. Energy measurements show that Janus achieves weeks to months of autonomous operation, depending on the use case configuration. Finally, several large-scale campaigns exemplify its practical usefulness in real-world contexts.

Autonomous Assembly Method of 3-Arm Robot to Fix the Multipin and Hole Load Plate on a Space Station

Using space stations for a large number of observation, exploration, and research is a necessary way to fully develop space technology. It is a necessary means of space experiment to install the extravehicular experimental load by using the load plate. However, the extravehicular environment is full of danger, which poses a threat to the health and even safety of astronauts. Using robots to replace astronauts to complete this task can effectively reduce the threat to astronauts. Aiming at the problem that the configurations of existing space robots have difficulty in balancing the contradiction between complexity and dexterity, our previous work proposes a 12-DOF 3-arm robot and preliminarily explores the feasibility of its large-scale ability. This paper focus on the 8-DOF redundant dexterous manipulator composed of 2 of the robot arms. In view of the difficulties in solving the inverse kinematics of the redundant manipulator, the challenges of complex environmental lighting, and difficulties of matching multiple groups of holes and pins in the load plate assembly task, the research on the autonomous assembly of the load plate is carried out. The main work is as follows: (a) A variable D-H parameter inverse kinematics solution method is proposed, which lays a foundation for humanoid dexterous operation planning of the robot. (b) An autonomous operation method based on visual guidance and variable parameter admittance control is proposed. Finally, the safety and robustness of the robot in the autonomous assembly of the load plate with multipins and holes are successfully verified by experiments.

DEVELOPMENT OF AUTOMATIC MODE DETECTION SYSTEM BY IMPLEMENTING THE STATISTICAL ANALYSIS OF SHIP DATA TO MONITOR THE PERFORMANCE

The shipping industry depends on a global regulatory framework to operate efficiently. The industry is currently facing various technical and regulatory challenges. Performance monitoring, vessel optimisation, reduction of emissions and maintenance have become high priorities for ship operators. The marine industry is also moving towards autonomous operation to reduce human error. The rate of sensor technology implementation has increased and also raised new technological challenges. The analysis of sensor data creates new challenges to achieve operational excellence. This paper presents the implementation of statistical analysis on ship data and develops a system to automatically detect the vessel operational modes based on sensor data.

Packet Flow Capacity Autonomous Operation Based on Reinforcement Learning

As the dynamicity of the traffic increases, the need for self-network operation becomes more evident. One of the solutions that might bring cost savings to network operators is the dynamic capacity management of large packet flows, especially in the context of packet over optical networks. Machine Learning, particularly Reinforcement Learning, seems to be an enabler for autonomicity as a result of its inherent capacity to learn from experience. However, precisely because of that, RL methods might not be able to provide the required performance (e.g., delay, packet loss, and capacity overprovisioning) when managing the capacity of packet flows, until they learn the optimal policy. In view of that, we propose a management lifecycle with three phases: (i) a self-tuned threshold-based approach operating just after the packet flow is set up and until enough data on the traffic characteristics are available; (ii) an RL operation based on models pre-trained with a generic traffic profile; and (iii) an RL operation with models trained for real traffic. Exhaustive simulation results confirm the poor performance of RL algorithms until the optimal policy is learnt and when traffic characteristics change over time, which prevents deploying such methods in operators’ networks. In contrast, the proposed lifecycle outperforms benchmarking approaches, achieving noticeable performance from the beginning of operation while showing robustness against traffic changes.

Data Driven Virtual Flow Metering: Leveraging AI and Edge Computing for Continuous Multiphase Flow Measurement

This paper describes the use of data-driven virtual flow metering (VFM) for continuous multiphase flow measurement, which has been developed and tested in an oil field well pilot in Austria. 12 ESP (Electric Submersible Pump) wells have been modelled and fine-tuned within the pilot. Hardware-based test separators were used to conduct quality control evaluations on the predicted production rates and calibrate the well models as required. For the practical deployment of VFM systems, we have addressed the need for optimized learning and scalability of the artificial intelligence (AI) models by means of what we call soft-sensing and will explain how to successfully deploy this technology on wells with artificial lift. Notably, the application of this software-based, soft-sensing VFM in combination with hardware-based multiphase flow measurement bears the potential to significantly reduce the CAPEX cost for future metering infrastructure investments and even reduce the OPEX of existing metering hardware by extending the duration of metering cycles. This makes data-driven VFM an economical option even for low-producing wells. Details of the well pilot project conducted with OMV in Austria will be provided. The use of soft-sensing VFMs via cloud computing for continuous multiphase flow measurement is a step toward the closed-loop, fully autonomous operation of oil fields.

Interventions and intersections: institutional environment and local level autonomy in LEADER. A comparative study

In 2010, when hope emerged that the new conservative government would improve the governance of the LEADER Programme, the Naturama Alliance, a co-operative network of seven Hungarian LAGs, issued a Declaration that summarised procedural issues to be addressed by a revision[1]. After introducing the alliance, the first chapter was entitled “Decentralisation and Autonomy”, indicating the direction of the desired shift towards a more autonomous operation. The LEADER Programme is scrutinised in this article from the point of view of autonomy and local democracy, exploring to what extent these are linked with or distinct from higher level governance transformations towards decentralisation or recentralisation. Theoretical approaches derived from rural and government studies are interpreted in the first sections of the paper, exploring the debate regarding the correlation of autonomy and local democracy and the way it is manifested in LEADER. Most authors regard LEADER as a promoter of local democracy and identify a positive correlation between democracy and an enhanced local autonomy. However, a consensus among scholars also seems to be unfolding from these studies suggesting that the scope of ‘LEADER democracy’ is mostly narrow, restricting participation to more resourceful social groups due both to the ‘thematic filters’ of the Local Development Strategy and to ‘procedural filters’, such as capacities allocated to the staff for animation and assistance to overcome difficulties of application. The empirical research background of this article is provided by two case studies, which were conducted in 2018-2019, one in England (Northumberland Uplands) and one in Hungary (Balaton Uplands), two states with complex recent histories and trajectories in terms of devolution of governance to lower levels and local autonomy. The secondary interpretation of these case studies focuses on the degree of participation and autonomy of LAGs. The analysis reveals that the degree of autonomy (and to some extent of participation) declined in both countries in the last iteration compared to the 2007-13 programming cycle. It has also been uncovered that rather than the ‘post transition’, recentralised Hungarian context, it was the British institutional system and governance tradition that permitted more top-down intervention and less autonomy for the LAGs.
