Along withthe increasing population density and dense multi-story buildings around Kampung Wisata Jodipan (KWJ) Malang, it has an impact on the group of villagers who are still children. With so many dense buildings, there is limited space for children to interact or play. this results in a reduced area for social interaction and interaction withthe surrounding natural environment. the purpose of this research is to create a design basis or design recommendation for a child-friendly play and interaction area. this research was conducted through several methods such as interviews, behavioural observation through a behavioural setting approach, and Bing Creator Image feature in the form of inputting several word interventions based on predetermined parameters. the results obtained from this research were to produce several new images (based on predetermined parameters) to be used as the basis for the design of the Bing Image Creator feature. the instructions used in the feature are based on physical, cognition, perception, emotion, and social parameters according to the conditions in KWJ Malang.

Basic vital signs such as heart and respiratory rates (HR and RR) are essential bio-indicators. their longitudinal in-home collection enables prediction and detection of disease onset and change, providing for earlier health intervention. this type of data collection, interpretation and evaluation is especially valuable for older adults facing myriads of health challenges. However, respiration harmonics and intermodulation cause strong disturbances to much weaker heartbeat signals, thus robust vital signs monitoring remains elusive. In this paper, we propose VitalHub, a robust, non-touch vital signs monitoring system using a pair of co-located Ultra-Wide Band (UWB) and depth sensors. By extensive manual examination, we identify four typical temporal and spectral signal patterns and their suitable vital signs estimators. We devise a probabilistic weighted framework (PWF) that quantifies evidence of these patterns to update the weighted combination of estimator output to track the vital signs robustly. We also design a "heatmap" based signal quality detector that achieves near-human performance differentiating signal corruptions from large motion. To monitor multiple co-habiting subjects in-home, we leverage consecutive skeletal poses from the depth data to distinguish between individuals and their activities, providing activity context important to disambiguating critical from normal vital sign variability. Extensive experiments show that VitalHub achieves 1.5/3.2 "breaths/beats per minute" (denoted by "bpm") errors at 80-percentile for RR/HR, approaching the 1.2/1.5 bpm error "ceiling" of an idealistic but impractical oracle. We also reveal how existing techniques for harmonics and intermodulation rely on presumed signal patterns thus may fail under real-world dynamic changes.

In modern railway construction, manual on-site detection of traction power foundation interfaces can be unsafe and inefficient, especially in scenarios involving high piers. To address this issue, an intelligent detection approach has been proposed based on modular design principles. this approach integrates computer vision technology and a PID flight control algorithm to enhance safety and efficiency. the proposed solution includes an autonomous bolt detection system designed and implemented using a Matrice 300 RTK (Real-Time Kinematic) quadrotor UAV (Unmanned Aerial Vehicle) equipped with a high-performance onboard computer, Manifold 2, a visible light camera H20, and a depth camera with a visual laser range-finder. this system replaces the traditional detection method, reducing manual involvement and improving detection accuracy. the proposed system has been successfully applied and demonstrated in the field, resulting in significantly higher detection precision.

this paper presents a new method to design adaptive Proportional-Integral-Derivative (PID) controllers which optimize a performance criterion (integral absolute error or integral square error) subject to constraints such as controlled variable, manipulated variable and rate of change constraints. the design method is applicable to linear or nonlinear processes. Modeling of such processes is done using a linear ARX model. In addition, the design method is independent of the PID controller type and accounts for controllers with proportional or derivative action on the control error or the process variable. the proposed design method is not analytic in nature, but rather it is implemented using existing MATLAB optimization functions and demonstrated using simulation experiments for linear and nonlinear processes.

Oil extraction screw presses are widely used in agriculture and food industry. In most cases, they are not equipped with complicated control systems due to the necessity of reducing their price and providing sufficient reliability. therefore, such presses cannot reach the best efficiency (productivity, performance), while processing different seeds and kernels. the present paper is focused on development of the enhanced control allowing for monitoring the operational parameters of the screw press and adjusting them in accordance with user-defined technologically prescribed ones. the research methodology contains a thorough analysis of the press design and operational peculiarities, and the development of functional (block), circuit, and breadboard diagrams of the control system. In order to verify the initially stated ideas of control strategies, the simulation models of the control systems are implemented in the TinkerCAD and SolidWorks software, and the experimental prototype of the screw press is correspondingly improved. the presented control system and press regulation strategies can be effectively implemented by engineers and technologists while developing new and enhancing existing designs of screw presses.

the advancement of computer science has led to significant transformations in the educational approach adopted by colleges and universities. this shift has emphasized independent learning behaviors, particularly informal learning. Consequently, there is a growing need to incorporate the planning and design of informal learning spaces into campus development strategies. this paper presents an analysis of the characteristics of informal learning behaviors observed on campus, as well as an exploration of the underlying demands associated with such activities. Based on these findings, the article proposes the strategic placement of informal learning spaces within campus planning. this proposition is examined from three distinct perspectives: the functional configuration, spatial structure, and place-making represent the macro-meso-micro levels. the paper takes the campus planning design of Guangdong Hotel Management College as an example to explore the strategies employed and the effectiveness achieved in facilitating informal learning. Furthermore, we focus on three key aspects: the multi-level informal learning function system, the layout of shared informal learning spaces, and the creation of personalized informal learning environments.
