Impulsive disturbance commonly appears in audio signals. During the last few decades, a number of denoising approaches has been proposed for the removal of this particular type of noise. An advanced class of denoising algorithms emerged from the recent compressive sensing (CS) paradigm. Sparsity or high concentration of audio signals in some specific transformation domains, such as, for example, the discrete cosine transform (DCT) domain, can be engaged in procedures for the detection of corrupted samples. Since in the case of impulsive noise only a subset of samples is highly corrupted, upon detection of their positions, these disturbed samples can be further considered as unavailable, and reconstructed using sophisticated CS procedures. In this paper, we investigate the possibility to apply Laplacian filter in conjunction with the compressive sensing reconstruction, in the removal of impulsive disturbance from audio signals.

Vehicle-to-Everything (V2X) is a promising technology that aims to resolve many problems of current transportation systems by supporting a wide-scale of Intelligent Transport System (ITS) use cases. V2X communications use channels (distinctive frequency domains from the ITS band) to provide radio resources for an increasing set of cooperative ITS applications. ETSI standardized the Service Announcement (SA) facility to advertise available services on ITS access channels. In the scope of this paper, we try to analyze the effects of the SA messages on the ITS control channel. We investigate different service deployment strategies and examine how the SA, CA (Cooperative Awareness), and the CP (Collective Perception) services could be deployed. We also provide initial results on details about the expected channel occupancy.

The paper addresses acoustic vehicle detection and speed estimation from single sensor measurements. We predict the vehicle's pass-by instant by minimizing clipped vehicle-to-microphone distance, which is predicted from the mel-spectrogram of input audio, in a supervised learning approach. In addition, mel-spectrogram-based features are used directly for vehicle speed estimation, without introducing any intermediate features. The results show that the proposed features can be used for accurate vehicle detection and speed estimation, with an average error of 7.87 km/h. If we formulate speed estimation as a classification problem, with a 10 km/h discretization interval, the proposed method attains the average accuracy of 48.7% for correct class prediction and 91.0% when an offset of one class is allowed. The proposed method is evaluated on a dataset of 304 urban-environment on-field recordings of ten different vehicles.

This paper outlines an example method and trial scenario phases for extending the existing tools for maritime surveillance across the maritime regions of Europe. There are continuous dedicated efforts throughout European collaborations for advancing the features of Common Information Sharing Environment (CISE), which is a European Union (EU) initiative for ubiquitous information sharing across the maritime and land borders, as well as between the national sectors. The EFFECTOR EU project introduces a novel concept in the information exchange: the data lake, intended for providing a common smart data repository for diverse and comprehensive data analysis and storage that emanates from diverse sources within the local, regional, national, and international scope. Setting up of the data lake facilities and broadened information exchange is established and validated through early trials planned to be conducted in the project. Administration for Maritime Safety and Port Management (AMSPM) is integrating maritime surveillance data from Montenegro in the EU information exchanges and vice versa. The EFFECTOR project's French maritime trial offers an implementation of the broadened scope of uses of advanced data exchanges, analysis storage, and retrieval. A case of retroactive data analysis and deductions is to be demonstrated through collaboration of AMSPM in the French maritime trial with other project partners. The trial scenario planning includes two vessels coming into the French waters near Marseille from distant ports, one via a stop-over in Montenegro and the other from Portugal.

This study aims to determine the factors that impact people's behavioural intentions to use mobile banking in Indonesia. The UTAUT technique is being utilised to explore the factors that impact people's inclinations to use mobile banking services. Following the revision of the questionnaire, which was based on earlier research, it was sent via a Google form to users who used m-banking in Indonesia. A questionnaire was provided to participants based on the purposive sampling method. In order to evaluate for convergent validity, discriminant validity, and path coefficient, the data was analysed using SmartPLS. It has been demonstrated that social influence, perceived security, and performance expectation all substantially impact behavioural intention to use m-Banking. On the other hand, the expectation of effort had no significant influence on behavioural intention to use mobile banking. According to the findings of this study, firms must prioritise effort expectation while also increasing other elements in the future.

The food market is changing dramatically in the last century as the world population is growing with the unprecedented pace. The wine industry is recognized as part of both agriculture and food industry, but also as a commodity. Developments in information technology and digitalization are playing a major role in the introduction of new solutions in agriculture and food production. The idea is to improve productivity of farms and vineyards, improve quality of agriculture products by optimizing irrigation, pesticide usage, and overall efficiency of the process. Furthermore, the consumer awareness about food products, its quality and origin, is on the constant rise. The information about the product throughout the whole “farm-to-fork”, or in this case “vineyard-to-glass”, value chain needs to be collected and utilized by all the participating stakeholders, in order to get a better, healthier, and more affordable product. This paper address the considerations related to implementation of a blockchain-based transparency and data provenance in the food value chain, more specifically with a focus on the wine industry.

Shape Memory alloys are specific materials that have the ability to change their shape and return to a memorized state caused by a change in temperature or a change in load. This paper presents the corrosion analysis of Shape Memory CuAlNi alloy (copper, aluminum and nickel) in different marine environments. The CuAlNi alloy was exposed to various sea and atmosphere influences over a period of six months. Chemical analysis of corroded alloys was performed using EDX (Energy Dispersive X-ray Spectrometer) analysis, and it was determined which marine environment has a dominant influence on the corrosion process. By applying regression analysis, the dependence of the alloy composition and the amount of oxygen was checked, which indicates the intensity of the corrosion process.

The e-learning system, is usually defined as a teaching and learning activities that is done with a computer, which evolves alongside with the evolution of the web. During the COVID-19 Pandemic, schools are forced to make a switch to the distance learning methods. With some previous research on studies about satisfaction using TAM, ECM and ISS, a conceptual framework was created to create a further study on Satisfaction. A total of seven hypotheses were created on this research that connects six variables from TAM, ECM, and ISS. As the survey was conducted to 400 high school students in Indonesia who uses the e-learning, the data was processed and calculated using SmartPLS using the PLS and Bootstrapping calculation. After the convergent and discriminant validity and the path analysis were conducted, it was found out that all of the hypotheses were accepted. However, there are some limitations in this study, which include sample and variable limitations.
