DPW Safety, at the Garage and in the Field, are you keeping up?
This 40 minute prsentation was developed for the 2014 Norfolk-Bristol-Middlesex Highway Association.Spring Technical Session.
This presentation discusses road construction worker safety hazards and fatalities. It notes that over 844 roadway construction workers died from 1995-2002, mostly from motor vehicle or construction equipment accidents. Specific dangers discussed include workers on foot being at risk from multiple hazards like construction vehicles, impaired drivers, and large blind spots that vehicle operators have. The presentation emphasizes the importance of having traffic control plans, using flaggers and signs properly, restricting access points and backing zones for vehicles, and workers wearing high-visibility clothing. It provides examples of regulations on backing safety for dump trucks to protect workers on foot.
Use these OSHA-based recommendations to help prevent accidents when backing up construction or other workplace vehicles. Across the U.S., 79 backover deaths occurred on the job in 2011. Properly trained spotters are a proven technique to help keep workers safe, but other methods also are effective.
RIDDOR requires reporting of work-related injuries, diseases, and dangerous occurrences in Great Britain. It aims to generate reports for authorities to examine incidents and trends and develop prevention strategies. Employers must report accidents that result in death, major injuries such as fractures or amputations, the inability to work for more than seven days, and reportable diseases diagnosed by a doctor. Dangerous occurrences like building collapses or fires causing more than a day's work suspension must also be reported. The responsible person, usually the employer, must make reports. An accident book should be used to record all incidents.

Health & Safety For Water Treatment Plant OperatorsDavid Horowitz
The document discusses health and safety issues at water treatment facilities. It covers common hazards like slips and falls, strains and sprains, and exposure to toxic gases. It also discusses the Globally Harmonized System for classifying chemicals and communicating hazard information. Physical hazards include flammability and reactivity. Health hazards can be acute like corrosivity or chronic like carcinogenicity. The system standardizes labels, pictograms, and safety data sheets to clearly communicate hazard information. Proper training and a phased implementation process are needed to transition chemical management programs.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Adaptive synchronous sliding control for a robot manipulator based on neural ...IJECEIAES
Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.
