China has fully automated for installing crash barriers, completing them quickly and with excellent quality. We rarely use such methods here.

‌Cheap LED bulbs may not be worth buying, mainly because their components such as capacitors may be of poor quality, resulting in a short life and easy failure. ‌ Here are the specific reasons: ‌Quality issues‌: Low-quality LED bulbs may use low-cost materials and processes, resulting in poor overall quality, such as poor quality capacitors that are easy to damage, poor heat dissipation materials and structures, which will affect the life and stability of the bulbs. ‌Health risks‌: Low-quality LED bulbs may have problems such as blue light hazards and flickering. Long-term use may cause damage to the eyes and skin, and even cause headaches, photosensitive epilepsy and other problems. ‌Safety hazards‌: Low-quality LED bulbs may be more prone to safety accidents such as short circuits and fires, posing a threat to personal and property safety. Cost issues: The price of each electronic component of LED bulbs is basically stable. The electronic components required for circuit protection design, temperature control design, etc. have a different quality and price, including heat dissipation materials, such as aluminum, copper, copper substrates, etc. The type of heat dissipation material used and the amount of use directly determine the cost increase or decrease. In other words, a better quality product must meet the requirements, and the cost is there, and it cannot be as low as a low-quality product. Therefore, when buying LED bulbs, it is recommended to choose products with more reasonable prices and guaranteed quality to ensure the use effect and safety. ‌ Of course, don't be superstitious about big brands. A large part of their high prices is advertising costs and lucrative profits. If you want to buy high-quality LED products at reasonable prices, you have to admit that you need to seek Chinese manufacturing; It must be emphasized that most of the brands that truly specialize in LED car light bulbs are in China. China has a complete LED car light industry chain, so according to customer needs, there are low to high quality, and our SNGL is the best LED car light bulb brand in China. The design and quality are not inferior to Philips at all. It has a history of more than ten years and is a professional LED car light bulb. In terms of component quality, LED chips, light pattern design, brightness, service life, heat dissipation materials and structure, adaptability, lighting effects, on-road test results, etc., our SNGL has performed well. You are welcome to buy it.

3D Gaussian Splatting for Real-Time Radiance Field Rendering paper page: Radiance Field methods have recently revolutionized novel-view synthesis of scenes captured with multiple photos or videos. However, achieving high visual quality still requires neural networks that are costly to train and render, while recent faster methods inevitably trade off speed for quality. For unbounded and complete scenes (rather than isolated objects) and 1080p resolution rendering, no current method can achieve real-time display rates. We introduce three key elements that allow us to achieve state-of-the-art visual quality while maintaining competitive training times and importantly allow high-quality real-time (>= 30 fps) novel-view synthesis at 1080p resolution. First, starting from sparse points produced during camera calibration, we represent the scene with 3D Gaussians that preserve desirable properties of continuous volumetric radiance fields for scene optimization while avoiding unnecessary computation in empty space; Second, we perform interleaved optimization/density control of the 3D Gaussians, notably optimizing anisotropic covariance to achieve an accurate representation of the scene; Third, we develop a fast visibility-aware rendering algorithm that supports anisotropic splatting and both accelerates training and allows realtime rendering. We demonstrate state-of-the-art visual quality and real-time rendering on several established datasets.
