Application of custom-made joint prostheses in wrist
Abstract: The wrist joint is a highly mobile functional joint. Wrist conditions including traumatic and degenerative arthritis, rheumatoid arthritis, and giant cell tumors of the distal radius, cause significant pain and mobility impairment. In joint surgery, the decision to use joint prostheses to reconstruct joint function is greatly influenced by the characteristics of the prosthesis (Mok et al., 2016). However, traditional implants have limitations such as shape mismatch, inadequate implantbone interface strength which causes loosening, and poor bone ingrowth (Zhang et al., 2014).

摘要：在受限硬件环境下，包括物联网在内的面向产品的操作系统面临着难以同时高效管理海量实时任务并执行资源密集型应用的重大挑战。为弥补该类嵌入式操作系统与通用操作系统的性能鸿沟，在信息论指导下，本文构建了一种优化的实时操作系统XIRAC。XIRAC利用香农信息论来调节处理器的工作负载，最大限度减少上下文切换，并通过最大化系统熵容限实现进程抢占。与以往仅将信息论用于任务优先级匹配的方法不同，XIRAC将最大熵集成到实时操作系统（RTOS）与调度算法的内核中。随后，将若干常见的无限制任务从应用层迁移至系统内核，以优化海量的系统参数。描述了这种架构转变的优势，包括优化的系统性能、可扩展性和适应性。从这种集成中衍生出一种新兴编程范式，称为"对象模拟编程"。XIRAC在多种产品中的实际应用展示了更多优势，包括缩短学习曲线、消除对库函数和线程的依赖、优化芯片潜能、提高产品开发的竞争力。本文对上述优势进行了全面总结，并通过实际案例与应用探讨了其影响。
