The marketing channels have been transformed by the presence of the internet and online platforms. The influence is profound, especially for the digital marketing sector. In the context of the global epidemic, the frequency of offline purchases by customers has decreased. Digital marketing strategies are of great importance for SMEs. With the aid of knowledge management tactics, the digital marketing process can be accessed more systematically. This research aims to develop a digital marketing framework through knowledge management tactics by taking a Thai dairy company context. To fulfill the objective, this study uses focus groups, text mining, and the RACE digital marketing planning model. © 2021 ACM.

Involution symmetry quantification using recurrences

Physical Review E 2024年第2期110卷 024203-024203页

Symmetries are ubiquitous in science, aiding theoretical comprehension by discerning patterns in mathematical models and natural phenomena. This work introduces a method for assessing the extent of symmetry within a time series. We explore both microscopic and macroscopic features extracted from a recurrence plot. By analyzing the statistics of small recurrence matrices, our approach delves into microscale dynamics, facilitating the identification of symmetric time series segments through diagonal macroscale structures on a recurrence plot. We validate our approach by successfully quantifying involution symmetries for three-dimensional dynamical models, specifically, order-2 rotational symmetry in the Lorenz '63 model, and inversion symmetry in the Chua circuit. Our quantifier also detects symmetry breaking in the modified Lorenz model for El Niño phenomenon. The method can be applied in a versatile manner, not only to three-dimensional trajectories but also to univariate time series. Symmetry quantification in time series is promising for enhancing dynamical system modeling and profiling.

Manufacturers of credit and debit card terminals lend their products to retailers, retaining responsibility for repairing or replacing devices upon verification of malfunctions or cosmetic defects. The logistic operator, which processes up to ten thousand products daily, must assess each device's condition through tests and manual visual inspections. Depending on the evaluation, a terminal may be returned to the client or sent to the manufacturer's tech center for repair. This inspection process is highly subjective and prone to human error, as different inspectors may assess the same device inconsistently. To address these inconsistencies, we developed a visual inspection system specifically for evaluating the LCD conditions of payment termi-nals. The hardware includes a 3D-printed structure to optimize image acquisition, an active illumination scheme, and a camera to capture images of the terminals. The desktop application features a YOLOv8 object detection model to highlight defects on the terminal's screen, complemented by a user-friendly interface with various functionalities. Our system improved the efficiency and accuracy of inspections, providing operators with a more reliable tool that ensures consistency. The final model achieved a mean Average Precision (mAP) of 77.4% and a processing speed of 88 milliseconds on CPU. Additionally, the real-time application interface offers low-latency usability, further enhancing the inspection process. After thorough model training and testing conducted in collaboration with the terminal manufacturer, the system has demonstrated its reliability for deployment at the production level.

Ensuring safety in workplaces such as industry and civil construction requires the use of personal protective equipment (PPE). Enhancing compliance with PPE regulations or employing educational measures through a deployable device, which can also restrict access to hazardous areas without proper safety equipment, is crucial to mitigating workplace accidents and reducing the risk of fatalities or disability. This paper proposes the development of a device equipped with embedded machine learning models that use a camera to monitor workers and enforce the usage of PPE. These models are deployed on an Arduino Nano 33 BLE Sense, integrated with an OV7675 camera shield, to capture images and employ our trained computer vision model to classify the usage of safety helmets. The compact size of the trained and quantized model, weighing only 59 KB, taking about 595 milliseconds total time, 92.5% accuracy, demonstrates its efficiency. This innovation not only promotes the adhesion to safety protocols, but also presents significant benefits in scientific and economic contexts.

Characteristics of Lantung Fiber and the Effect of Alkali Treatment and Water Absorption on the Mechanical Properties of Lantung Fiber Reinforced Composites

This study aims to investigate the effect of alkali treatment and water absorption on the mechanical properties of composites reinforced with lantung fibers. Lantung fibers were alkali-treated for one and two hours at room temperature using 4% and 6% sodium hydroxide solutions. Composite samples reinforced with lantung fibers were prepared by the hand lay-up method. The composite samples were soaked in distilled water at 60°C for 1080 hours or 45 days. All samples were subjected to tensile tests, flexural tests, and impact tests based on ASTM D638-02, D790-02, and D5942-96 standards. Alkali treatment was proven to be effective in improving the mechanical properties of lantung fiber reinforced composites. Lantung fibers soaked in 4% sodium hydroxide solution for 2 hours gave the highest mechanical properties. The initial absorption process of lantung fiber reinforced composites soaked in distilled water at 60°C was found to approach the Fickian diffusion behavior. Following an hour-long immersion in a 6% sodium hydroxide solution, lantung fibers had the lowest diffusion coefficient of 9.15x10-12 m2/s and the highest water content of 4.89%. The mechanical properties of lantung fiber reinforced composites showed insignificant decrease in impact, flexural, and tensile strength after water absorption so that lantung fiber is recommended for use in wet environmental conditions. © 2025 Jordan Journal of Mechanical and Industrial Engineering.

This research explores the integration of speculative design within Taipei's public bicycle service to propel the achievement of net-zero emission strategies and Sustainable Development Goals (SDGs). It introduces a sustainable energy model tailored to enhance the public bicycle system amid rising global environmental challenges. Using the User Experience Questionnaire (UEQ) and the System Usability Scale (SUS), the study evaluates Taipei's YouBike 2.0 service and its associated apps, revealing a positive reception but noting a preference for enjoyment over practical utility and room for improvement in app perception. Further, it presents a pilot survey leveraging data-driven micro-electricity generation technology in urban infrastructure, integrating cutting-edge technologies like AI and real-time data to foster sustainable urban mobility. The research culminates in speculative design scenarios that envision future e-bike systems seamlessly integrated into smart city networks, suggesting a transformative role for e-bikes in urban transport sustainability. © Copyright owned by the author(s)

A detailed study of the relationship between synoptic climate phenomena and high rainfall is essential to predict the occurrence of hazardous rainfall. We use Global Satellite Mapping of Precipitation (GSMaP) data and ERA-5 Reanalysis data to identify extreme rainfall events and the triggering anomalies. Extreme rainfall was identified as a 97th percentile maximum threshold. Then, k-means clustering applied to cluster spatial patterns of extreme rainfall. The influencing climatic factors anomaly reveals the synoptic climate phenomena in the Western Maritime Continent that provoke extreme rainfall on Borneo Island. Strong northerly moisture transport in December-January–February and March–April-May seasons may be related to cold surge events and lead to heavy rainfall in northern or western Borneo. Westerly wind anomalies toward the Philippines that can occur in all seasons may be associated with Madden Julian Oscillation and cause heavy rainfall around North Kalimantan. Also, positive sea surface temperature anomalies in the Java Sea may trigger wet anomalies around Central Kalimantan. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
