The carbonate type consists mainly of parasite, allanite, and bastnaesite, while REE phosphate group comprises mainly monazite and xenotime. They are accompanied by thorite and zircon. REE-bearing quartz vein is associated with cassiterite, pyrite, chalcopyrite, sphalerite, and tourmaline. The hydrothermal fluid that plays a role in REE mineral precipitation is subdivided into three stages: early (> 316oC - 316oC), medium (< 316oC – 210oC), and late (<210oC190oC). The δ18O range which is 12, 7 ‰ – 13 ‰, and the δ34S range are 3, 9 ‰ – 5, 5 ‰ indicate that the origin of hydrothermal fluid comes from mixing fluids of both meteoric and magmatic sources, and also influenced by metamorphic waters. While the source of sulphur is granitic and sedimentary rocks. REE phosphate is thought to have formed in the early magmatic crystallization stage except for monazite formed in the medium magmatic-hydrothermal and late hydrothermal stages. Primary REE carbonate may have formed in a medium hydrothermal-magmatic stage except for parasite and allanite, they may have formed in late-stage hydrothermal. Chalcopyrite and sphalerite seem to be associated with REE minerals in the medium and late hydrothermal stages.","PeriodicalId":39047,"journal":{"name":"Journal of Electrical and Electronics Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89410523","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 goal is to reduce the total transportation cost, of delivering resources from sources to destinations. The literature demonstrates that various approaches have been designed with a single goal in mind, although TPs are not always developed with a bi-goal in mind. Solving transportation difficulties with several objectives is a common task. In this study, a new method for addressing multi-criteria TP using geometric means, along with a novel approach of the Ant Colony Optimization algorithm (ACO) for solving multi-objective TP in a fuzzy environment. Fuzzy numbers have been used to solve real-world problems in various domains, including operations research and optimization. The ACO Algorithm has long been recognized as a viable alternative strategy for solving optimization problems. The purpose of this study is to provide a unique approach for organizing fuzzy numbers as well as enhancements to the ACO algorithm for solving the Multi-Objective TP model. Our method, such as Geometric Mean Ant Colony Optimization Algorithm (GMACOA), outperforms other methods in terms of objective values. Numerical examples are provided to demonstrate the method in comparison to various current methods.","PeriodicalId":39047,"journal":{"name":"Journal of Electrical and Electronics Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83982989","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}

Success in fighting land degradation requires an improved understanding of its causes, impact, degree and acquaintance with climate, soil, water, land cover and socio-economic factors. The present study aimed to assess the advanced of Remote Sensing (RS) and Geographic Information System (GIS) to quantify land degradation risk in Adea woreda. Remotely sensed data provide timely, accurate and reliable information on degraded lands at certain time intervals in a cost-effective method. This paper presents the effect of land-use changes on land degradation by utilization of remote sensing and GIS methods due to un wise agriculture and urbanization activities in the period 2000–2022. The analysis is based on the processing of Landsat 7 and Landsat OLI 8 satellite images from 2000 and 2022. In the analysis of satellite images, the supervised classification maximum likelihood method was used. The study demonstrated that about 42.77 % of the study area has undergone very high risk of degradation, whereas 44.26% of the area has undergone moderate degradation. About 12.50% of the total area was characterized by marginally degraded. The results indicated that the salinity, alkalinity and water logging are the main common degradation hazards of the Adea woreda.","PeriodicalId":39047,"journal":{"name":"Journal of Electrical and Electronics Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83985686","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}

Multi-Dimensional Spectral Process for Cepstral Feature Engineering & Formant Coding 基于倒谱特征工程的多维谱处理与构象编码

{"title":"Multi-Dimensional Spectral Process for Cepstral Feature Engineering & Formant Coding","authors":"","doi":"10.33140/jeee.01.01.01","DOIUrl":"https://doi.org/10.33140/jeee.01.01.01","url":null,"abstract":"The fundamental frequency feature is essential for Automatic Speech Recognition because its patterns convey a paralanguage and its tuning normalizes other speech features. Human speech is multidimensional because it is minimally represented by three variables: the intonation (or pitch), the formants (or timbre), and the speech resolution (or depth). These variables represent the hidden states of the local glottal variation, the vocal tract response, and the frequency scale, respectively. Computing them one by one is not as efficient as computing them together, so this article introduces a new speech feature extraction approach. The article is introductory; it focuses on the basic concepts of our new approach and does not elaborate on all applications. It demonstrates that the unit of a cepstral value, which is a spectral value of spectrums, is a unit of acceleration since its discrete variable, the quefrency, can be expressed in Hertz-per-microsecond. The article shows how to produce refined voice analysis from robust estimates and how to reconstruct speech signals from feature spaces. And it concludes that the pitch track of the new approach is as good as two open-source pitch extractors. Combining multiple processes, attenuating background noises, and enabling distant-speech recognition, we introduce the Speech Quefrency Transform (SQT) approach as well as multiple quefrency scales. SQT is a set of frequency transforms whose spectral leakages are controlled per a frequency-modulation model. SQT captures the stationarity of time series onto a hyperspace that resembles the cepstrogram when it is reduced for pitch track extraction.","PeriodicalId":39047,"journal":{"name":"Journal of Electrical and Electronics Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74561670","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}
