The project manager's role and influence on the project's overall outcome have fascinated many academicians, researchers, and practitioners. The project manager's leadership and human skills play a vital role in the project's outcome;therefore, it is imperative for these competencies to be identified, learned, and leadership styles to be adopted. This study aims to define the most relevant competencies to multidimensional project success and their interrelationship. The quantitative method was used by applying a survey to project managers and team members working in the public sector of Pakistan. The results suggest that a combination of emotional, managerial intelligence, and transformational leadership are stronger predictors of multidimensional public project success. This study has shown that management and leadership need to be integrated to achieve better results. Project managers need to combine soft and hard skills, leadership competencies, and management to engage with people and be effective in terms of processes, tasks, and objectives. © 1973-2011 IEEE.

In frequency domain, wavelet coefficient is one of the characteristics of ERG signal which is hidden in frequency-domain. This paper aims to develop a tool for analyzing the constituent frequencies and time of interest in the dog's ERG signal using wavelet analysis. We design a lowpass filter to reduce noise during the measurement of ERG response. ERG dataset was obtained for the light intensity series and their constituent frequencies are analyzed by using the continuous wavelet transform (CWT). The results show that, in time-domain, as light intensity increases, both amplitudes of a-wave and b-wave are higher. We can visualize the noise interference in the ERG signals. Then a lowpass filter is designed to attenuate the noise effect. The filtered signals have lower a-, and b-waves' amplitude which affect the important characteristics in time domain. Therefore, we choose to filter signal from 26ms onward, the main components are recovered, and the filtered signal becomes smoother. In frequency-domain, the peak magnitude of wavelet coefficients is increased as light intensity increases. © 2023 IEEE.

Home Energy Management systems (HEMS) equip users with additional control over their energy consumption, allowing them to schedule economically how their appliances may be used. The essence of HEMS is to provide energy and cost saving while avoiding user inconvenience. A significantly high number of the proposed HEMS solutions in literature are focused mainly on developing algorithms for appliance scheduling while putting less emphasis on the selection of the appropriate technologies and modelling techniques. Moreover, the current rise of the internet-of-Things (IoT) and low-cost microcontroller hardware present further opportunities for development of better HEMS. This work contributes to the study of HEMS in three ways. Firstly, it proposes an IoT-based HEMS framework. Secondly, it provides a brief comparison suitable for low-cost computing hardware. Lastly, it presents design considerations necessary for implementing HEMS. The analysis shows that the considerations must review available Demand-side management programmes, communication technologies and energy driving variables. © 2021 IEEE.

The storage and transport of fresh fruits require dense sensor monitoring to preserve high food quality by adaptive control of cooling parameters. Digital Twins are the method of choice for the integration of services for sensor measurement forwarding, data conversion and predictive modelling. Further resampling services compensate for deviating and non-synchronized sensor intervals. The Digital Twin platform was demonstrated for monitoring and predicting condensation on the fruit surface in a cooling chamber with apples.

The exponential growth of academic publications has made scholarly research recommender systems indispensable tools for researchers. These systems rely on diverse evaluation metrics to assess their effectiveness and relevance. This paper provides a comprehensive review and analysis of these metrics, categorizing them into accuracy, ranking, diversity, user-centric, coverage, temporal, and computational metrics. By employing a mixed-methods approach, combining systematic literature review and empirical analysis, we identify the prevalence and application of these metrics across various scholarly domains such as literature, conferences, and reviewers. Our findings highlight the widespread use of traditional metrics like precision, recall, and Fl-score, while emphasizing the growing importance of novel metrics such as unexpectedness and serendipity, especially in literature and conference recommendations. We also underscore the domain-specific nature of metric selection, with user-centric evaluations more prominent in literature recommendations, and ranking-focused metrics dominant in conference and reviewer recommendations. Furthermore, the study reveals a significant gap in the use of temporal and computational metrics, suggesting key areas for future research. This review offers valuable insights for researchers and practitioners, guiding them in metric selection and highlighting potential directions for enhancing the effectiveness, adaptability, and user satisfaction of scholarly recommender systems.

The chemical industry is one of the largest consumers of fossil raw materials in the European Union (EU). Phasing out the use of fossil carbon both for energetic and material use (decarbonization/defossilization) requires the introduction of alternative processes and systems of production and consumption. One strategy that brings forward the defossilization of the chemistry sector is the use of biomass (bio-based carbon) as a raw material to produce bio-based chemical products. Our analysis focuses on the intersection of the forest-based bioeconomy, bio-based chemical production, and consumer preferences. It points out how the sustainability transition of the chemical industry changes the forest-based bioeconomy policy subsystem in the EU. Drawing on the Political process inherent Dynamics Approach (PIDA), we apply a mixed-methods research design that integrates three scientific perspectives in an interdisciplinary approach. We illustrate how shifts in forestry, the chemical industry, and consumer preferences change the forest-based bioeconomy policy subsystem. Numerous strategies and goals referring to international agreements have been introduced by the EU in recent years and new actors from the chemical industry are entering the policy subsystem. Yet, new instruments are needed and developed for the regulation of the carbon cycle and negative emissions. The study provides directions for research on the defossilization of the chemical industry through the use of forest biomass and points out potential conflicts and trade-offs in production, consumption, and regulation. © 2025 The Authors

Stochastic Online Optimization for Cyber-Physical and Robotic systems

We propose a novel gradient-based online optimization framework for solving stochastic programming problems that frequently arise in the context of cyber-physical and robotic systems. Our problem formulation accommodates constraints that model the evolution of a cyber-physical system, which has, in general, a continuous state and action space, is nonlinear, and where the state is only partially observed. We also incorporate an approximate model of the dynamics as prior knowledge into the learning process and show that even rough estimates of the dynamics can significantly improve the convergence of our algorithms. Our online optimization framework encompasses both gradient descent and quasi-Newton methods, and we provide a unified convergence analysis of our algorithms in a non-convex setting. We also characterize the impact of modeling errors in the system dynamics on the convergence rate of the algorithms. Finally, we evaluate our algorithms in simulations of a flexible beam, a four-legged walking robot, and in real-world experiments with a ping-pong playing robot. Copyright © 2024, The Authors.
