作者： Mohamed Saban Otman Aghzout Alfredo Rosado-Muñ oz Dpt. Electronic Engineering ETSE School of Engineering Burjassot Spain Dpt. Computer Science ENSA School of Engineering Tetouan Morocco

The integration of Industry 4.0 technologies in agriculture will reduce the increasing challenges of agricultural process around the globe. The real-time farm management with high degree of automation will greatly improve productivity, agri-food supply chain efficiency and food safety. This paper describes a fully customized LoRa-based IoT system that aims for a low-cost, low power and wide range wireless sensor network targeted for smart farms. The presented system integrates already existing Programmable Logic Controllers (PLC) typically used to control multiple processes and devices such as water pumps, certain machinery, etc. along with a newly developed network of wireless LoRA sensors distributed over the farm. A Telegram bot is also included as novelty for automated user communication via this mobile phone messaging application. The network structure was deployed and tested. The developed integrated system also includes a cloud-based monitoring application to provide remote visualization and control for all the farming environment.

International Multi-Topic ICT Conference (IMTIC)

作者： Farzana Kulsoom Iraj Fatima Hassan Nazeer Chaudhry Aneeqa Gul Adeel Akram Telecommunication Engineering Dpt. University of Engineering and Technology Taxila Pakistan Computer Science Dpt. Barani Institute of Technology Rawalpindi Pakistan

The UAV-mounted base station has been integrated into 5G and beyond to provide communication in an emergency when conventional systems fail due to some reason. Moreover, it is also used in coverage enhancement and for other strategic purposes. In this work, we have considered a MIMO-OFDM based UAV system that is inclined to fast-fading channels due to the continuous motion of UAVs. Due to the mobility of UAVs, there is a frequency and timing offset which must be estimated for proper and seamless communication. For that purpose, we have proposed a data-aided maximum likelihood-based scheme that efficiently estimates the carrier frequency and timing offset. Results show that our algorithm outperforms the state-of-the-art system in terms of MSE.

Asia and South Pacific Design Automation Conference

作者： K. Taki Dpt. of Computer and Systems Engineering Faculty of Engineering Kobe University Kobe Japan

The objective of this embedded tutorial is to give an overview for the state of the art of the pass-transistor logic technologies and their future prospects. The paper gives a survey summary for recent researches and developments on the pass-transistor logic technologies based on more than 100 surveyed papers that have been published after 1983. The number of publications has been rapidly increased after 1995, which shows recent quick growth of research activities. The survey includes several different viewpoints, such as circuit technologies, design and synthesis methodologies, applications and commercial use, etc. The circuit technologies and synthesis methodologies are roughly grouped into two categories, one of which has a close relation to BDD, while the other does not. Circuit technologies are also categorized into different axes, such as differential structure or single-rail structure, NMOS pass-transistors or CMOS, static circuits or dynamic, etc. Features of each pass-transistor logic family are explained along with these classification axes. For the most recent topics, commercial products by Japanese companies and cell/tool businesses in venture business companies in US are also reported. Several recent papers made performance comparisons of pass-transistor logic and CMOS, that are also reported with a discussion of future prospects.

Autotuning of an in-line pH control system

Autotuning of an in-line pH control system

International Conference on Emerging Technologies and Factory Automation (ETFA)

作者： Pedro Mercader Kristian Soltesz Alfonso Baños Dpt. Computer and Systems Engineering University of Murcia Murcia Spain Dpt. Automatic Control Lund University Lund Sweden

A novel autotuning procedure is presented through application to an industrial in-line pH control system. The procedure has three advantages over classical relay auto-tuners: experiment duration is very short (no need for limit-cycle convergence); all data is used for identification (instead of only peaks and switch instances); a parameter uncertainty model is identified and utilized for robust controller synthesis.

IEEE Workshop on Applications of Signal Processing to Audio and Acoustics

作者： Mina Mounir Peter Karsmakers Toon van Waterschoot Dpt. of Electrical Engineering KU Leuven Leuven Belgium Dpt. of Computer Science KU Leuven GEEL Belgium

Musical note onset detection is a building component for several MIR related tasks. The ambiguity in the definition of a note onset and the lack of a standard way to annotate onsets, introduce differences in datasets labeling, which in turn makes evaluations of note onset detection algorithms difficult to compare. This paper gives an overview of the parameters influencing the commonly used onset detection evaluation measure, i.e. the F1-score, pointing out a consistently missing parameter which is the overall time shift in annotations. This paper shows how crucial this parameter is in making reported F1-scores comparable among different algorithms and datasets, achieving a more reliable evaluation. As several MIR applications are concerned with the relative location of onsets to each other and not their absolute location, this paper suggests to include the overall time shift as a parameter when evaluating the algorithm performance. Experiments show a strong variability in the reported F1-score and up to 50% increase in the best-case F1-score when varying the overall time shift. Optimizing the time shift turns out to be crucial when training or testing algorithms with datasets that are annotated differently (e.g. manually, automatically, and with different annotators) and especially when using deep learning algorithms.

While extensively explored in text-based tasks, Named Entity Recognition (NER) remains largely neglected in spoken language understanding. Existing resources are limited to a single, English-only dataset. This paper addresses this gap by introducing MSNER, a freely available, multilingual speech corpus annotated with named entities. It provides annotations to the VoxPopuli dataset in four languages (Dutch, French, German, and Spanish). We have also releasing an efficient annotation tool that leverages automatic pre-annotations for faster manual refinement. This results in 590 and 15 hours of silver-annotated speech for training and validation, alongside a 17-hour, manually-annotated evaluation set. We further provide an analysis comparing silver and gold annotations. Finally, we present baseline NER models to stimulate further research on this newly available dataset. © 2024, CC BY.

Smart cities have been a very active research area in the past 20 years, while continuously adapting to new technological advancements and keeping up with the times regarding sustainability and climate change. In this context, there have been numerous proposals to expand the scope of smart cities, focusing on resilience and sustainability, among other aspects, resulting in terms like smart sustainable cities. At the same time, there is an ongoing discussion regarding the degree in which smart cities put people at their centre. In this work, we argue toward expanding the current smart city definition by integrating the circular economy as one of its central pillars and adopting the term smart (and) circular city. We discuss the ways a smart and circular city encompasses both sustainability and smartness in an integral manner, while also being well-positioned to foster novel business activity and models and helping to place citizens at the heart of the smart city. In this sense, we also argue that previous research in smart cities and technologies, such as those related to Industry 4.0, can serve as a cornerstone to implement circular economy activities within cities, at a scale that exceeds current activities that are based on more conventional approaches. We also outline current open challenges in this domain and research questions that still need to be addressed.

作者： Scutari, Gesualdo Palomar, Daniel Facchinei, Francisco Pang, Jong-Shi University of Rome Italy Department of Electronic and Computer Engineering University of Catalonia Barcelona Spain University of Rome Rome Italy Dpt. of Industrial and Enterprise Systems Engineering University of Illinois at Urbana-Champaign Urbana United States

The use of optimization methods is ubiquitous in communications and signal processing. In particular, convex optimization techniques have been widely used in the design and analysis of single user and multiuser communication systems and signal processing algorithms (e.g., [1] and [2]). Game theory is a field of applied mathematics that describes and analyzes scenarios with interactive decisions (e.g., [3] and [4]). Roughly speaking, a game can be represented as a set of coupled optimization problems. In recent years, there has been a growing interest in adopting cooperative and noncooperative game theoretic approaches to model many communications and networking problems, such as power control and resource sharing in wireless/wired and peer-to-peer networks (e.g., [5][12]), cognitive radio systems (e.g., [13][17]), and distributed routing, flow, and congestion control in communication networks (e.g., [18] and [19] and references therein). Two recent special issues on the subject are [20] and [21]. A more general framework suitable for investigating and solving various optimization problems and equilibrium models, even when classical game theory may fail, is known to be the variation inequality (VI) problem that constitutes a very general class of problems in nonlinear analysis [22]. © 2010 IEEE.
