The Given

Presented are the developments using methods of monitoring the psychophysiological state of a person that are designed to improve the work safety of the employees at the metallurgical enterprises. A wearable device was developed for taking readings of the psychophysiological reactions (pulse, galvanic skin response, body and environmental temperature, etc.), and for determining the location of an employee within the production area in real time. The device can also record a sharp change in the position of a person in space, which indirectly indicates an emergency. The device indicates and reads changes throughout the shift and transfers to the server; when one of the monitored parameters increases, a message is generated on the operator monitor about a problem in the employee condition and his location. Previously developed program «System for monitoring the psychophysiological state of an operator at the metallurgical industry» with the help of a software processes the information from the device and warns the operator about the occurred hazard, and, also, suggests the ways for solving the problem. However, the decision itself remains with the operator. Under the conditions of working process modeling using the given parameters, the situations (accidents, personnel selection) were simulated that were close to real ones, which allowed to conduct a comparative analysis of the maximum and minimum permissible characteristics of the psychophysiological reactions for the employees of the metallurgical production. The developed device and monitoring system can significantly reduce (or completely prevent) the number of errors and accidents at the production site that are provoked by the influence of the human factor.

The Given

In real-time systems, a task or a set of tasks needs to be executed and completed successfully within a predefined time. Those systems require a scheduling technique or a set of scheduling methods to distribute the given task or the set of tasks among different processors or on a processor. In this paper, a new novel scheduling approach to minimize the overhead from context switching between several periodic tasks is presented. This method speeds up a required response time while ensuring that all tasks meet their deadline times and there is no deadline miss occurred. It is a dynamic-priority technique that works either on a uniprocessor or several processors. In particular, it is proposed to be applied on multiprocessor environments since many applications run on several processors. Various examples are presented within this paper to demonstrate its optimality and efficiency. In addition, several comparison experiments with an earlier version of this approach were performed to demonstrate its efficiency and effectiveness too. Those experiments showed that this novel approach sped up the execution time from 15% to nearly around 46%. In addition, it proved that it reduced the number of a context switch between tasks from 12% to around 50% as shown from simulation tests. Furthermore, this approach delivered all tasks/jobs successfully and ensured there was no deadline miss happened.

We study some properties of integro splines. Using these properties, we design an algorithm to construct splines \(S_{m+1}(x)\) of neighbouring degrees to the given spline \(S_{m}(x)\) with degree \(m\). A local integro-sextic spline is constructed with the proposed algorithm. The local integro splines work efficiently, that is, they have low computational complexity, and they are effective for use in real time. The construction of nonlocal integro splines usually leads to solving a system of linear equations with band matrices, which yields high computational costs.   doi:10.1017/S1446181121000316

This paper presents a rule structure called Concept Based Censor Production Rule (CBCPR) that deals with real time cases. CBCPR is an extension of a rule structure called Censored Production Rule (CPR). CPR is a standard rule structure with UNLESS slot, which contains various censor conditions that might rarely happen and prevent the action of the rule to be taken. The more time one has, the more censor conditions one can check. The major extension of CPR is by concentrating on what is called concept. The concept is what about the user needs the decision. Each rule will have a certain concept title that specifies its job. In addition, in every CBCPR structure, at least one slot related to UNLESS part in the rule is existing, where each UNLESS slot is related to a certain category having censor conditions concerned with the concept. The structure will help the system to give more certain answers within the given time for the real-time systems instead of keep checking unnecessary censor conditions for the same concept of different UNLESS categories.

For using surface electromyography (sEMG) in various applications, the process consists of three parts: an onset time detection for detecting the first point of movement signals, a feature extraction for extracting the signal attribution, and a feature classification for classifying the sEMG signals. The first and the most significant part that influences the accuracy of other parts is the onset time detection, particularly for automatic systems. In this paper, an automatic and simple algorithm for the real-time onset time detection is presented. There are two main processes in the proposed algorithm; a smoothing process for reducing the noise of the measured sEMG signals and an automatic threshold calculation process for determining the onset time. The results from the algorithm analysis demonstrate the performance of the proposed algorithm to detect the sEMG onset time in various smoothing-threshold equations. Our findings reveal that using a simple square integral (SSI) as the smoothing-threshold equation with the given sEMG signals gives the best performance for the onset time detection. Additionally, our proposed algorithm is also implemented on a real hardware platform, namely NI myRIO. Using the real-time simulated sEMG data, the experimental results guarantee that the proposed algorithm can properly detect the onset time in the real-time manner.

Purpose The purpose of this paper is to investigate the critical time window for pro-active construction accident prevention and response. Large to small organisations throughout the entire construction supply chain continue to be challenged to adequately prevent accidents. Construction worker injuries and fatalities represent significant waste of resources. Although the five C’s (culture, competency, communication, controls and contractors) have been focusing on compliance, good practices and best-in-class strategies, even industry leaders have only marginal improvements in recorded safety statistics for many years. Design/methodology/approach Right-time vs real-time construction safety and health identifies three major focus areas to aid in the development of a strategic, as opposed to tactical, response. Occupational safety and health by design, real-time safety and health monitoring and alerts and education, training and feedback leveraging state-of-the-art technology provide meaningful predictive, quantitative and qualitative measures to identify, correlate and eliminate hazards before workers get injured or incidents cause collateral damage. Findings The current state and development of existing innovative initiatives in the occupational construction safety and health domain are identified. A framework for right-time vs real-time construction safety and health presents the specific focus on automated safety and health data gathering, analysis and reporting to achieve better safety performance. The developed roadmap for right-time vs real-time safety and health is finally tested in selected application scenarios of high concern in the construction industry. Originality/value A strategic roadmap to eliminate hazards and accidents through right-time vs real-time automation is presented that has practical as well as social implications on conducting a rigorous safety culture and climate in a construction business and its entire supply chain.

Haptic Sensation

In this paper, we propose a method which modifies free-form surfaces to pass through not only specified points, but also specified curves with the assistance of haptic navigation. Using the method, designers of aesthetic shapes, such as a car body, can manipulate the model of the shape in real-time looking at its stereoscopic image and feeling its haptic sensation as if there were a clay model. The haptic navigation helps designers, letting them capture and recognize the object easily and constraining their operation to the appropriate direction or along the specified geometric element. In addition, the designers can get force feedback proportional to the modification quantity. To obtain a smoothly modified shape, we introduce correction functions to the given surface equations. A correction function distributes the effect of the change over the whole shape or the specified region according to the distance of the point in the normal direction of the given surface. The values of the correction function are 1 at the indicated point and 0 at the boundaries, and the shape is modified to keep the original smoothness. The correction values of the functions at the indicated points are determined to pass through all of them by solving a linear equation. To apply this to the specified curves including boundaries of a trimmed surface, we treat points composing the curve similarly to the point specification by representing them with a Cardinal spline. We have confirmed that the system is effective to manipulate a shape with its feeling and that smooth surfaces are obtained in real time as designers want.
