This study used electrical impedance tomography (EIT) to illustrate the distribution of moisture inside the walls of the buildings under study. The first task is to discover the ideal settings of hyperparameters used in machine learning algorithms to increase the efficiency of obtaining reliable tomographic images. The second aim of the research is to choose the optimal method of converting measurements into images. The process of turning input observations into output photos is handled by machine learning models. This is called an ill-posed problem or an inverted problem that is difficult to solve because there are not enough arguments. Ensuring the selection of the correct model hyperparameters is an essential task of machine learning. The selection of these hyperparameters has a direct impact on the quality of the reconstruction. Using the k-nearest neighbors algorithm as an example, this article shows how hyperparameter optimization can be applied to regression and classification models. This technology was created to track and visualize the distribution of moisture inside the walls of buildings and other structures. The facts revealed during the investigation showed that the proposed techniques are effective.","PeriodicalId":396821,"journal":{"name":"2023 International Interdisciplinary PhD Workshop (IIPhDW)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128195281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This also applies to the novel unmanned underwater vehicle (UUV) class MUM (Large Modifiable Underwater Mothership) which features a modular structure and variable shape, thus requiring a generalized motion control approach that adapts to the specific vehicle configuration. Regarding MUM's maneuvering devices, the control system generalization is achieved by means of actuator allocation which distributes the motion controller output to the available actuators. Consequently, this paper proposes an actuator allocation approach that treats conventional propulsion units and VBS jointly. Inspired by optimization-based solutions known from dynamically positioning ships, the selected allocation method employs a problem formulation based on model predictive control (MPC) in order to optimize usage of the actuators subject to their characteristics and physical limits. The application of the allocation algorithm to an actuator configuration with VBS is presented and results from early trials in simulation are shown.","PeriodicalId":396821,"journal":{"name":"2023 International Interdisciplinary PhD Workshop (IIPhDW)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127200170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The platforms that provide the learning content and are equipped with analytical tools and are able to provide guidance to the participants in the educational process by means of artificial intelligence are referred to as Learning Experience Platforms within the framework of the research. In the educational practice of two countries learning experience platforms Bettermarks and Eduten Playground have been chosen for case study analysis. Data collection methods: analysis of open sources and interviews with users (teachers). These platforms allow learners to personalize what they are learning, how they are learning and when / where they choose to learn. Through such platforms, participants in the learning process can identify specific skills or knowledge gaps by accessing an analysis of their teaching-learning activities and use suggestions for action to improve their achievement. The article presents the empiric information on the benefits of these platforms in the teaching/learning practice as well challenges for their effective use.

In this work, the capacity crunch is dealt with by utilizing an optical multiple-input and multiple-output (MIMO) technology integrated with higher-order modulations (HOMs) as they lead to higher spectral efficiency. The low cost is achieved using intensity modulation / direct detection (IM/DD) system with a multi-mode fiber (MMF) transmission link. Contrary to an SMF channel, a highly dispersion-impaired MMF is equalized using a jointly designed pre- and post-equalization (PPE) filter, which consists of just two-taps pre-equalizer. A numerical optimization is defined to optimize the pre-and post-equalizer coefficients within the provided power and cost budgets. This work is the first investigation of a singular value decomposition (SVD) based joint-PPE scheme with a 1km long MMF link. The obtained results reveal that the signal-to-noise-ratio (SNR) gains of 5.48 dB and 10.57 dB at 10–4 bit-error rate (BER) for PAM-2 and PAM-4 compared to post-equalization only (PE-only) respectively. From the results, the SVD-assisted joint-PPE yields benefit in the presence of an MMF channel.","PeriodicalId":396821,"journal":{"name":"2023 International Interdisciplinary PhD Workshop (IIPhDW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126505309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
