Individuality in clinical gait analysis is often quantified by an individual's kinematic deviation from the norm, but it is unclear how these deviations generalize across different walking speeds and ground slopes. Understanding individuality across tasks has important implications in the tuning of prosthetic legs, where clinicians have limited time and resources to personalize the kinematic motion of the leg to therapeutically enhance the wearer's gait. This study seeks to determine an efficient way to predictively model an individual's kinematics over a continuous range of slopes and speeds given only one personalized task at level ground. We were able to predict the kinematics of able-bodied individuals at a wide variety of conditions that were not specifically tuned. Applied to 10 human subjects, the individualization method reduced the RMSE between the model and subject's kinematics over all tasks by an average of 2% (max 52%) at the ankle, 27% (max 59%) at the knee, and 45% (max 83%) at the hip. Our results indicate that knowing how an individual subject differs from the average subject at level ground alone is enough information to improve kinematic predictions across all tasks. This research offers a new method for personalizing robotic prosthetic legs over a variety of tasks without the need of an engineer, which could make these complex devices more clinically viable.

Sustainable supply chain management (SSCM) is crucial, yet it is still difficult to implement in companies. This happens because there are various factors known as critical success factors (CSFs) that have a role in the implementation of plans and operational performance in sustainability. The study used multiple-case studies and analyzed four different types of companies that have implemented external sustainability. Based on the within-case analysis, a list of CSFs for external sustainability implementation that differs between organizations is generated for each case. Furthermore, the effects of contingencies toward CSFs implementation are established.

This paper presents a benchmark problem for fault diagnosis of an internal combustion engine that has been formulated and solved. The objective is to design a diagnosis system using and incomplete model information training data that only contains a limited set of fault realizations. Six different solutions to the benchmark, that were presented at the IFAC Safeprocess symposium 2024, are described and evaluated. The contribution of this paper is the benchmark and the presentation of six different solutions in one paper. The paper is intended to provide a starting point for engineers and researchers who work with fault diagnosis and monitoring of technical systems.

This study aims to determine, explain and analyze the human development index or the so-called HDI. To find out the factors that affect the human development index. The Human Development Index is one indicator of the creation of development that is able to encourage economic growth. To measure the quality of human capital, the United Nations Development program (UNDP) introduced the concept of the quality of human capital which was named the Human Development Index or the Human Development Index (IPM). The human development index (HDI) is a strategic indicator that is widely used to see the efforts and performance of development programs as a whole in an area. In this case, HDI is considered as an illustration of the results of development programs that have been carried out several years earlier. Likewise, the progress of development programs in a period can be measured and indicated by the HDI at the beginning and end of the period. HDI is a measure to see the impact of regional development performance which has a very broad dimension, because it shows the quality of the population of an area in terms of life expectancy, intellectuality and decent living standards. The Human Development Index is one indicator of the creation of development that is able to encourage economic growth. To measure the quality of human capital, the United Nations Development program (UNDP) introduced the concept of the quality of human capital which was named the Human Development Index or the Human Development Index (IPM). The HDI provides a combined three-dimensional measure of human development, namely the health dimension measured by life expectancy, the education dimension measured by the level of adult literacy and average length of schooling and the purchasing power dimension which has a decent standard of living measured by purchasing power parity.
