Distribution Reliability and Automation

Distribution Reliability and Automation

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Distributed Loads: Problem Solving

Distributed Loads: Problem Solving

Beams are structural elements commonly employed in engineering applications requiring different load-carrying capacities. The first step in analyzing a beam under a distributed load is to simplify the problem by dividing the load into smaller regions, which allows one to consider each region separately and calculate the magnitude of the equivalent resultant load acting on each portion of the beam. The magnitude of the equivalent resultant load for each region can be determined by calculating...

Distributed Loads

Distributed Loads

Distributed loads are a common type of load that engineers and scientists encounter in various practical situations. Distributed loads often refer to a type of load spread over a surface or a structure and can be modeled as continuous force per unit area.
For example, consider a bookshelf filled with books stacked vertically adjacent to each other. The weight of the books is evenly distributed over the length of the shelf. As a result, the pressure at different locations on the surface of the...

Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Multiple Pipe Systems

Multiple Pipe Systems

Multipipe systems consist of complex configurations of interconnected pipes designed to transport fluids efficiently across intricate networks. They are essential in engineering applications requiring precise control over flow distribution, pressure, and head loss. They are categorized into series, parallel, loop, and network configurations, each distinguished by unique flow characteristics and applications.
Series Configuration
In a series configuration, fluid flows sequentially from one pipe...

Transformers in Distribution System

Transformers in Distribution System

Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...

Area of Science:

Industrial Internet of Things (IIoT)
Communication Systems
Data Modeling

Background:

The Industrial Internet of Things (IIoT) faces challenges with massive data transmission due to diverse protocols and limited traditional system capacity.
Existing communication systems struggle with concurrency and throughput, hindering efficient industrial data exchange.

Purpose of the Study:

To propose a distributed high-availability message communication model for IIoT (DUA-MQTT) to overcome traditional system limitations.
To enhance information processing capabilities by developing an information-modeling model (MAC-GC) for industrial unstructured text data.

Main Methods:

Developed the DUA-MQTT model integrating distributed MQTT protocol within the OPC UA architecture for improved concurrency and throughput.
Designed the MAC-GC model for hierarchical annotation of industrial unstructured text data to generate structured, OPC UA-compliant data nodes.

Main Results:

The DUA-MQTT model demonstrated a 28.6% reduction in end-to-end latency and a 22.2% increase in throughput compared to traditional models.
The MAC-GC model achieved high performance in accuracy (0.9701), recall (0.9601), and F1 score (0.9651) for unstructured data modeling.

Conclusions:

The DUA-MQTT model significantly enhances data transmission concurrency and efficiency in IIoT environments.
The MAC-GC model effectively improves the utilization and accuracy of unstructured industrial data through structured modeling.
