This study aimed to assess the prevalence and severity of visual impairment and its associated factors in diabetic patients in Libya. Methods: This cross-sectional study included 2365 DM patients (4730 eyes). Most participants were aged 30 - 49 (38.3%) and 50 - 69 (50.8%) with a nearly equal gender distribution (47.8% males, 52.2% females). Type 2 diabetes was predominant (92.6%), and 62.9% had HbA1c levels of 7.5% or higher. Results: Diabetic retinopathy (DR) was present in 2068 eyes (43.8%), with mild non-proliferative diabetic retinopathy (NPDR) affecting 1178 eyes (25%), moderate NPDR 476 eyes (10.1%), severe NPDR 228 eyes (4.8%), and proliferative diabetic retinopathy (PDR) 186 eyes (3.9%). Diabetic maculopathy was observed in 621 eyes (13.1%), with CSME in 287 eyes (6.07%) and non-CSME in 334 eyes (7.06%). Non-retinal conditions included cataracts in 1938 eyes (41%) and glaucoma in 252 eyes (5.3%). Visual impairment was observed in 1159 patients (49%), with 534 (23%) experiencing mild impairment, 382 (18%) moderate impairment, and 243 (12%) severe impairment;142 patients (6%) were classified as legally blind. DR showed a strong association with visual impairment severity (p Conclusions: These findings underscore the urgency for targeted public health interventions to mitigate visual impairment in Libyan individuals with DM.展开更多

The theoretical foundation of this method is an elastic-plastic large deformation splinefinite strip method based on object-oriented programming. Combined with the computer graphicstechnology, the visual simulation of cold roll-forming is completed and the system is established.By analyzing common channel steel, the process is shown and explained including theory method, modeland result display. So the simulation system is already a kind of mature and effective tool toanalyze the process of cold roll forming.展开更多

It fosters collaboration and informed decision-making across diverse domains. Conversely, Python is indispensable for professional programming due to its versatility, readability, extensive libraries, and robust community support. It enables efficient development, advanced data analysis, data mining, and automation, catering to diverse industries and applications. However, one primary issue when using Microsoft Excel with Python libraries is compatibility and interoperability. While Excel is a widely used tool for data storage and analysis, it may not seamlessly integrate with Python libraries, leading to challenges in reading and writing data, especially in complex or large datasets. Additionally, manipulating Excel files with Python may not always preserve formatting or formulas accurately, potentially affecting data integrity. Moreover, dependency on Excel’s graphical user interface (GUI) for automation can limit scalability and reproducibility compared to Python’s scripting capabilities. This paper covers the integration solution of empowering non-programmers to leverage Python’s capabilities within the familiar Excel environment. This enables users to perform advanced data analysis and automation tasks without requiring extensive programming knowledge. Based on Soliciting feedback from non-programmers who have tested the integration solution, the case study shows how the solution evaluates the ease of implementation, performance, and compatibility of Python with Excel versions.展开更多

In this study, Markov Chain, Monte Carlo, Fourier Series, and weak stationary process were used to generate the daily weather data in software Matlab 6. 0, with the data input from 40 years' weather data recorded by Beijing Weather Station. The generated data includes daily maximum temperature, minimum temperature, precipitation and solar radiation. It has been verified that the weather data generated by the VS-WGEN were more accurate than that by the old WGEN, when twenty new model parameters were included. VS-WGEN has wide software applications, such as pest risk analysis, pest forecast and management. It can be implemented in hardware development as well, such as weather control in weather chamber and greenhouse for researches on ecological adaptation of crop varieties to a given location over time and space. Overall, VS-WGEN is a very useful tool for studies on theoretical and applied ecology.展开更多

To archive this purpose, in this article, we propose a Puzzle Programming System that uses jigsaw puzzles as an example of the application of physical visualization, which visualizes logical constraints to physical ones. This Puzzle Programming System aims to teach basic programming concepts by presenting the invisible constraints of programming language syntax using the visual constraints of jigsaw puzzle pieces. This system runs on an Apple iPad and was developed using the Unity game engine. We used YAML as a data format for serializing structured data for data management. By inviting high school students to try out a prototype, we could confirm the usefulness of the Puzzle Programming System. The experimental evaluation results also shed light on aspects of the game that need to be redesigned and parts where the visual programming model needs to be modified and expanded.展开更多

But those are usually not formed or created in our needs. Most of data providers deliver their data in Microsoft Excel spreadsheet, which is compatible with ArcGIS, the most widely used GIS （Geographic Information System） software in GIS sector. However, those table data contain much unnecessary information that do not need for a certain project. Using the raw data can increase processing times and reduce performance of geoprocessing tools. This study shows steps of how the raw data are being processed using ArcGIS ModelBuilder and Python script.展开更多
