Presently, Functionally Graded Materials (FGMs) are extensively utilised in several industrial sectors, and the modelling of their mechanical behaviour is consistently advancing. Most studies investigate the impact of layers on the mechanical characteristics, resulting in a discontinuity in the material. In the present study, the extended Finite Element Method (XFEM) technique is used to analyse the damage in a Metal/Ceramic plate (FGM-Al/SiC) with a circular central notch. The plate is subjected to a uniaxial tensile force. The maximum stress criterion was employed for fracture initiation and the energy criterion for its propagation and evolution. The FGM (Al/SiC) structure is graded based on its thickness using a modified power law. The plastic characteristics of the structure were estimated using the Tamura-Tomota-Ozawa (TTO) model in a user-defined field variables (USDFLD) subroutine. Validation of the numerical model in the form of a stress-strain curve with the findings of the experimental tests was established following a mesh sensitivity investigation and demonstrated good convergence. The influence of the notch dimensions and gradation exponent on the structural response and damage development was also explored. Additionally, force-displacement curves were employed to display the data, highlighting the fracture propagation pattern within the FGM structure.

Published: July 2024

3D reconstruction and visualization of plants are of great research value for their physiological characteristics. Large-scale datasets are required to train 3D reconstruction algorithms. Most of the current 3D plant datasets only focus on the parts above the ground surface. Roots, as the half below ground, are also critical for plant growth. There are few efforts to generate 3D root datasets. Existing 3D plant root datasets only contain a very limited number of reconstructed 3D models and the lack of ground truth, mainly because of the complexity of root structures and the inconvenience of obtaining root images and ground truth 3D structures. This paper creates a large virtual 3D plant root benchmark dataset, which not only contains extensive 3D root models; but also has 2D images captured from various angles, involving 1.2K 3D root structures and over 80K 2D root images. This large plant dataset enables testing of multiple 3D reconstruction algorithms to verify the reliability of the algorithms. Finally, multiple commonly used 3D reconstruction algorithms and the most recent state-of-the-art 3D modeling methods are tested on this dataset, which demonstrates the superb research values of this dataset to advance the 3D root modeling research.

Designing an Interpretable Question Answering System for Vertical Domains Based on Large Language Model and Knowledge Graph
Authors: Huang Xiaobin , Ku Chin Soon
Published: July 2024

Given the low interpretability of large language models (LLMs) due to their extensive parameters and intricate features, this study aims to enhance the understandability and interpretability of automatic QA systems powered by LLMs, thereby addressing a critical gap in the field. To achieve this, we introduce an interpretable architecture for a domain-specific LLM-based question-answering (QA) system. The research decomposes the QA system into six modules: operation recognition, intent recognition, normalization, triplet structured data conversion, knowledge graph querying, and query result processing. Through this approach, the input and output of each module in the QA system are human-readable text data, enhancing the interpretability of the QA system’s processing. The use of knowledge graph data increases the credibility of the answers provided by the QA system. The QA system architecture proposed in this study attempts to integrate the powerful natural language understanding capabilities of large language models with the data querying capacity of knowledge graphs, offering a reference for addressing the issue of low interpretability in automatic QA systems based on large language models (LLMs).
GPER-DDPG-Based Offloading Optimization for UAV-Assisted Mobile Edge Computing
Authors: Yu Siyuan , Zhang Xuxiu , Guo Zi
Published: July 2024

In recent years, the technology related to providing computing resources to ground users using Unmanned Aerial Vehicle (UAV) with Mobile Edge Computing (MEC) servers has received widespread attention. In edge computing scenarios with limited communication infrastructure, for the problem of difficulty in deploying conventional terrestrial base stations, this paper designs a UAV-based edge computing network (UAV-MEC) model. The network model adopts a partial offloading strategy, which enables the computational tasks of the ground devices (LD) to be partially executed on the local devices and partially offloaded to the edge computing servers of the auxiliary UAV. When facing computationally intensive and delay-sensitive computational tasks, LD and UAV have limited computational resources and energy, and how to optimize the offloading strategy becomes a key issue. In this paper, we propose an offloading optimization algorithm based on GPER-DDPG. The algorithm introduces the prioritized experience replay technique, adaptive action policy noise, and Actor network delay updating technique to improve the stability and convergence performance of the DDPG algorithm in complex environments. Experimental results show that the performance of the improved algorithm proposed in this paper improves about 10-12% over the performance of the DDPG algorithm.
Multimodal Trajectory Prediction Based on Sustainable Learning from Memory Networks
Authors: Zhang Wenxu , Zhang Xuxiu
Published: July 2024

In the field of trajectory prediction, when new scene data is continuously introduced, the system may forget the historical trajectory information that has been learned before, leading to the phenomenon of decreasing the prediction accuracy of previous scenes, which is called catastrophic forgetting. The Multi-Memo Net framework proposed in this paper is an instance-based approach that stores typical trajectories through a memory bank thereby establishing a direct link between the current and historical scenes. During training, self-encoders and decoders are used to efficiently memorize the feature expressions of past trajectories and future intentions; during prediction, the controller finds similar scenes that have occurred in history in the memory bank based on the past trajectories and contextual information for trajectory prediction, and ultimately obtains a multimodal trajectory prediction through K-means clustering, and while predicting, the model can keep updating the content of the memory bank to learn, thus iteratively optimizing the model prediction performance. Thus, the model prediction performance is iteratively optimized. Compared with baseline models such as Kalman filter and Memory Augmented Networks for Multiple Trajectory Prediction (MANTRA) model, the method in this paper has significant improvement in Average Displacement Error (ADE) and Final Displacement Error (FDE) metrics.

Authors: Merbawani Gigih Widy , Hartono Didik
Published: July 2024

For many university-level EFL students, speaking in a second language can be quite a challenge. It often involves grappling with the complexities of the L2 language. To help tackle these hurdles and boost students' speaking confidence, Oral Communication Strategies can be quite beneficial. In this research, we used a mixed-method approach, which included surveys via questionnaires and in-depth interviews. We received responses from 110 completed questionnaires and gained further data by interviewing 10 students. The findings revealed that students tend to rely on Oral Communication Strategies when they face difficulties in communicating in a second language. They often resort to such strategies, such as using gestures, facial expressions, miming, or sound imitation, especially when they struggle to explain a vocabulary item. These results are anticipated to be a valuable resource for educators and practitioners, assisting them in tailoring the curriculum and providing a more enriching learning experience for students learning a second language. The study's findings can help language learners and educators in higher education by using oral communication strategies to create effective learning environments for improved communication.

Published: July 2024

People interaction has changed along with internet development. Digital news (internet-based) is beginning to alter classical ones. The development of social media and other digital platforms is a result of the Internet development. Reading comprehension and audience skills are undoubtedly impacted by this, particularly for Generation Z because of shifting preferences for news-based-content consumption. By comparing Generation Z's preferences for classical and digital news sources, this study aims to comprehend the trends of news consumption in the digital age. This study used a quantitative approach using a descriptive methodology by employing a valid and reliable questionnaire to collect data that were then randomly distributed to 85 communication science students in semesters 2, 4, 6, and 8. The study's findings explain why communication science students do not vary significantly from other Generation Z students in terms of their preferences for news sources or how they consume them. However, since they study communication science, they are more astute when consuming news from contemporary sources that often include false information or aren't grounded in reality.

Published: July 2024

The 4-H Show Rabbit project focuses on all the aspects of showing rabbits according to the American Rabbit Breeders Association (ARBA) show guidelines, showmanship skills, and breed Standards of Perfection. Youth learn to asses a rabbit based on its Standard of Perfection, helping to identify faults and choose from reliable breeding stock. In the 4-H Show Rabbit project (visit http://florida4h.org for more information about this online project), youth learn the skills necessary for choosing a healthy rabbit, proper handling of a rabbit, rabbit health, and general care. This document, the Show Rabbit Record Book (4H RAR 12), familiarizes youth with the importance of record keeping as an integral part of project management. By tracking inventory, financial records associated with their project, rabbit health and grooming details, and related information such as monthly care schedules, show earnings, show registration/entry/remark cards, youth will be well prepared to relate their experiences in a written narrative as part of their project completion activities.

Field Evaluation of Container Nursery Irrigation Systems: Uniformity of Water Application of Sprinkler Systems
Authors: Haman Dorota Z. , Yeager Thomas H.
Published: July 2024

Why should I be concerned with the uniformity of my irrigation system? Why is it important to maintain high uniformity? This is important because high uniformity signifies that all the plants in the irrigated zone will receive almost the same amount of water in a given time. For sprinkler irrigation, it means that the depth of water application throughout the entire irrigated area is about the same. Consequently, uniform water application is necessary to maximize the efficiency of water use in the nursery and save water. There is a simple method to evaluate the uniformity of irrigation and the test should be performed at least once a year. The uniformity may change with time, and often simple repairs or changes can improve system performance.
Distiller Grains for Beef Cattle Feeding

Published: July 2024

In all, DGS is an excellent feed for beef cattle. This feed can provide both protein and energy in many beef cattle supplement feeding and backgrounding programs. With the increasing production of ethanol for fuel, the availability of DGS will only increase in the future. University research has indicated that DGS can be safely fed up to 40% of total diet (dry basis), and the possibility of greater inclusion rates does exist. With the increase in the availability of DGS, more research is currently being conducted at several institutions that will help to more clearly define acceptable feeding levels and feeding management practices for DGS.
Potassium Deficiency in Palms
Authors: Broschat Timothy K.
Published: July 2024

This document is about symptoms of potassium (K) deficiency among palm species. This disease appears first on the oldest leaves. Older leaflets of some palms such as Dictyosperma album (hurricane palm) are mottled with yellowish spots that are translucent when viewed from below. In other palms such as Dypsis cabadae (cabada palm), Howea spp. (kentia palms) and Roystonea spp. (royal palms), symptoms appear on older leaves as marginal or tip necrosis with little or no yellowish spotting present (Figures 2 and 3). The leaflets in Roystonea, Dypsis, and other pinnate-leaved species showing marginal or tip necrosis often appear withered and frizzled.
Checklist of Florida-Friendly Landscape Practices
Authors: Park Brown Sydney
Published: July 2024

A Florida-Friendly landscape is attractive, functional, and ecologically sound. Its creation and maintenance can be accomplished by using the landscape practices listed below. They are grouped according to how much money or labor they take to accomplish from easiest to most expensive and/or labor intensive. Even a simple practice—like raising the height on your lawn mower—can have significant, positive impacts on the landscape and the environment. The page number(s) that follow a practice refer to information in Florida-Friendly Landscaping™ Handbook for Home Landscapes which is available free from your local Extension office or online http://fyn.ifas.ufl.edu/materials/FYNHandbook-v1-2012.pdf.

Managing Florida Ponds for Fishing
Authors: Cichra Charles E.
Published: July 2024

Florida has thousands of natural and man-made ponds which range in surface area from less than 1/10 acre to greater than ten acres. Man-made ponds include dug-out and impounded waters, limerock pits, and sand or gravel pits, commonly called borrow pits. Fishing pressure on public waters is increasing due to Florida's rapidly growing population and the growing interest in fishing as a source of recreation and food. Competition for public fishery resources, coupled with the high cost of transportation to go fishing, has resulted in an increased interest in fishing private waters that are closer to home. These private ponds must, therefore, be more intensively managed to maintain good quality fishing for the pond owner's personal recreation or as a source of income.
Decapsulating Brine Shrimp Eggs
Authors: Watson Craig , Yanong Roy
Published: July 2024

Brine shrimp eggs, essential for feeding small fish in hatcheries, require separation from their non-digestible shells and unhatched eggs post-hatching. This document explains the decapsulation process using chlorine removing the outer shell, simplifying separation and sterilizing the eggs. This method improves hatch rates and allows unhatched eggs to be fed directly to fish. The decapsulation procedure involves soaking the eggs in water, treating them with bleach, and rinsing thoroughly. Decapsulated eggs can be stored in brine or hatched immediately in containers with specific conditions. This process adapts to various brine shrimp egg types, ensuring effective hatchery operations.

Simultaneous count data feature selection and clustering using Multinomial Nested Dirichlet Mixture
Authors: Alkhawaja Fares , Amayri Manar , Bouguila Nizar
Published: July 2024

The elevating effect of the curse of dimensionality in count data has made clustering a challenging task. This paper solves this by adopting the concept of feature saliency as a feature selection method in the context of using the Multinomial Nested Dirichlet Mixture (MNDM). The MNDM is a generalization of the Dirichlet Compound Mixture (DCM) that suffers from several limitations. The model learning is accomplished through the expectation-maximization method. The Minimum Message Length criterion is used to simultaneously determine the best number of components in the mixture with the updated selected features. At the price of convergence times, the results show better performance through different metrics, as the model aims to select the salient features and tune away the non-salient anomalistic features.
