Nowadays, it is essential to provide 3D digital reconstructions with the highest possible reliability and veracity. Archaeological sites within the framework of the building to be rebuilt are important. The data provided by Geographic Information Systems (GIS) can be extracted from different sources, and are a crucial tool to carry out the topographical survey in the context of Virtual Archaeology. Therefore, engineering and archaeology work hand in hand to form multidisciplinary teams with the aim of addressing the design of heritage cultural elements. The aim of this study was to represent the terrain associated with the "the Baker’s House", at the archaeological site of Torreparedones (Cordoba, Spain). The interest in this representation increased after the virtual reconstruction of the domus, which was performed to geographically place the house in its exact location. Two methodologies were used through different software and data to obtain the topographical survey. The first methodology was the one applied in QGIS 2.3.15 with data from the CNIG, and the second methodology was the one applied in Blender 2.90.0 using the Google Satellite database. Both methodologies were compared, analysing the time invested in the two processes, as well as the orography of the terrain, which was captured with a 360 panoramic picture taken on the site. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

The translation application was developed using Python and Visual Studio Code as the primary programming environment. Technological progress has led to the younger generation forsaking the Batak language in their daily interactions, perceiving it as inconsequential to their social circle and contributing to the decline of regional languages. There is concern that regional languages, namely the Batak language, may lose significance or face extinction if this trend persists. This translation program is being implemented to aid in preserving regional languages, specifically the Batak language, enabling it to conform to contemporary circumstances. The development of this translation engine utilized the Batak language dictionary. The process of designing, coding, and testing is responsible for creating this direct machine translation. The BLEU score is employed to assess the caliber of machine translation. The study's findings indicate that the % BLEU value for ten sentences was 32.3%. This score falls within the category of sentences whose meaning can be understood, but the sentence structure still needs development. The direct machine translation developed in this Web platform is highly proficient and practical. © 2023 IEEE.

Wonogiri Dam administratively located in Wonogiri Regency exactly in the upper reaches of Bengawan Solo Watershed. Wonogiri Dam is a multipurpose dam which is used as irrigation, raw water, hydroelectric power plant and flood control. The high impact of erosion and sedimentation became main issue in Wonogiri Dam caused by changes in land use at upstream area. Within 25 years the capacity of Wonogiri Reservoir was reduced by 65 million m3 from 440 million m3 in 1980 to 375 m3 in 2005 as recorded. One of parameter that used for assessment of the dam performance depends on erosion and sedimentation. This study aims to determine assessment of performance Wonogiri Dam in service of water needs due to erosion and sedimentation. Erosion and sedimentation analysis can be determined by using USLE (Universal Soil Loss Equation) and SRD (Sedimen Delivery Ratio) methods. As the result showed that erosion in Wonogiri Watershed has high erosion potential which gain 3,2 million m3/year. The Keduang Sub Watershed shows the highest level of erosion potential, which is between 1.175 million m3/year. The sedimentation rate result in Wonogiri Dam considered relatively high with rate value 1,948,000 m3/year. There for it is necessary that a comprehensive sedimentation management system is needed in the Wonogiri Watershed from both side, in technical and non technical aspect, such as reforestation or dredging activities. Based on the results of the analysis of the impact of erosion and sedimentation, it can be concluded that the performance evaluation of the Wonogiri Dam is include in the sufficient category because many activities have been carried out to restore the reservoir function to its original condition. © Published under licence by IOP Publishing Ltd.

Copy-move forgeries often exploit homogeneous regions in images with large-scale attacks to either highlight or conceal target objects. These manipulations are simple to execute but challenging to notice. Forgery detection techniques like Copy-Move Forgery Detection (CMFD) cannot detect these forged documents because they are unable to identify a sufficient number of effective keypoints in homogeneous areas, leading to inaccurate and inefficient results. SURF stands for Speeded-Up Robust Features and is used in this paper along with A-KAZE and Scale-Invariant Feature Transforms. According to our experiment, A-KAZE offers superior detection performance under diverse attacks, especially when it comes to large-scale attacks targeting homogeneous regions. A-KAZE is found to be more accurate than SIFT, SURF, and A-KAZE when applied to the NB-CASIA dataset, achieving detection accuracies of 89.2%, 93.9% and 98.98%.) © 2024 IEEE.

The increasing number of autonomous vehicles will result in a safety factor that must be maintained. One of the crucial prerequisites for this is proper localization, especially at intersections where most road accidents occur each year. This research is proposed to improve the localization process, which has drawbacks such as the inaccurate Global Positioning System (GPS) when satellite signals are blocked, and Light Detection and Ranging (LiDAR), which is expensive and needs heavy computing time. This is done by implementing the High Definition Map (HD Map) method, which maps the condition of an area that is stored as memory on an autonomous vehicle computer. The proposed system uses a monocular camera to be processed into a semantic segmentation feature map at the pixel level, then uses point cloud to reconstruct a 3D intersection model, which is then segmented semantically as well so that position data is obtained after merging using the occupancy grid and scoring function. The results of this CNN-based approach localization produce less accuracy and Mean Intersection over Union (MIoU) values with 60% average accuracy and 62.3 MioU when compared to GPS data and other 3D semantic segmentation systems, but the proposed approach can save costs and computational burden. © 2023 ICROS.

As the global population ages, the number of elderly people needing hearing aids is increasing. This paper proposed an architecture designed to enhance speech based on noise conditions. After noise types are identified by a Convolutional Neural Network (CNN) noise classification model, these noise conditions are combined with the noisy speech and input into a conditional Generative Adversarial Network (cGAN) for speech enhancement. The CNN noise classification model achieves an average recognition accuracy of nearly 92%, with a Kappa value as high as 0.88. The cGAN speech enhancement achieves lower error values in the Mel-Cepstral Distortion (MCD) measure. Although some parts of the human voice may be filtered out, the results demonstrate the potential development of the proposed algorithm. © 2024 IEEE.

This study explores the use of the YOLOv5 algorithm to detect loose fruits palm oil in plantations, improve collection efficiency, and reduce reliance on manual labor. Loose fruits have high economic value due to their oil content, but they are often not collected, resulting in financial losses and the growth of weeds around oil palm trees. Conventional manual methods are often ineffective; thus, automatic detection is required. The dataset comprises 525 images of loose fruits, covering complex conditions on plantations, and secondary data from Roboflow, including nontarget objects, such as rocks and dry leaves, to train the model to accurately distinguish loose fruits. During training, several parameters were optimized: batch size, learning rate, optimizer type, weight decay, and momentum, which showed that small batch sizes provided higher mAP50 values, whereas large batches increased mAP50:95, indicating the ability to detect objects at higher levels of complexity. Testing in a scenario with loose fruits clearly visible and partially covered with leaves or grass showed that YOLOv5 could detect loose fruits well despite some constraints in the obstructed environment. The results of this study show that, with appropriate parameter settings, YOLOv5 can be a reliable basis for automated loose fruit collection systems, potentially improving operational efficiency in oil palm plantations and contributing to the development of automation in the agricultural sector.

Being one essential part of the solutions we are developing to provide accessibility for blind persons, synthesized speech of mathematical content, although having evolved in naturalness in recent years, still keeps a characteristic of generating very long outputs, which makes it difficult for a person who uses a screen reader to memorize. Eye-gaze tracking has been useful for studying cognitive processes and student's effort in performing tasks therefore it seems attractive as a means to understand how people analyze, process, and break down extensive math expressions into smaller ones. This understanding can help to build a similar model of auditory rendering of MathML capable of avoiding cognitive overload. Therefore, we carried out an experiment to do a gaze-based analysis of reading and memorizing mathematical expressions. Our sample consisted of fourteen participants, and seven mathematical expressions were used in the experiment. The results showed that the computed complexity of the expressions and the average duration of eye-gaze fixations have a strong and significant relationship. Therefore, we conclude that the complexity variable must always be considered in the speech synthesis process of mathematical expressions. However, when considering why participants requested the repetition of an expression with not larger complexity during the memorization process, a tentative interpretation based on the number of MathML tree nodes and the computed complexity of the expressions was not enough to explain it, indicating that other factors need to be investigated. Although some answers to the research questions were not yet conclusive, we consider this research relevant because it points to directions for the work in order to minimize the cognitive processing and mental load of the synthesized speech rendering of mathematical expressions. © 2022 IEEE.

As a village that later developed into an area that resembled a colonial city at that time, Depok Lama had a concept of residential space that was different from the colonial settlements that existed during the Dutch colonial period. In other colonial settlements, the concept of settlement was the result of a design from the Dutch government, in the Depok Lama settlement the concept of residential space was formed from the activities of citizens directed by a will. This method is used to find a detailed picture based on facts about the beginning of the formation of Depok lama settlement through collecting Depok Lama maps, Chastelein's will, and observing city artifacts. The results of this study note that the concept of space that was applied at the beginning of the formation of the Depok Lama settlement was an unplanned concept of sustainability, prioritizing easy access to various main facilities in the Depok Lama settlement, forming a comfortable environment for the residents of Depok Lama in building their lives and improving they socio-economic quality. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
