Pilot and Numeric Relaying

Pilot and Numeric Relaying

Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Social Traps

Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Case Studies

Case Studies

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.

Self-Evaluation: Self-Enhancement and Self-Verification

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Nursing Evaluation

Nursing Evaluation

The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

Self-Evaluation Maintenance Model

Self-Evaluation Maintenance Model

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Area of Science:

Disaster response technology
Search and rescue systems
Sensor fusion for victim detection

Background:

Timely localization of injured survivors is critical for effective disaster response.
Existing methods may lack the precision or speed required for rapid victim identification.
Advanced sensor technologies offer potential improvements in search and rescue efficiency.

Purpose of the Study:

To propose and evaluate a novel sensor system for detecting living victims in simulated disaster environments.
To assess the individual and combined performance of CO₂ sensors, thermal cameras, and microphones.
To develop and test an algorithm for recognizing human sounds under rubble.

Main Methods:

Development of a sensor system integrating carbon dioxide (CO₂) detection, thermal imaging, and acoustic sensing.
High-fidelity simulation of a disaster area for performance testing.
Implementation and validation of a sound recognition algorithm for human vocalizations or noises.

Main Results:

The CO₂ sensor effectively narrowed down the search area, improving localization efficiency.
Thermal cameras accurately confirmed the position of victims within the reduced area.
Microphones, when used with other sensors, showed significant potential for casualty detection, supported by the developed algorithm.

Conclusions:

The integrated sensor system demonstrates a promising approach for enhancing the speed and accuracy of victim localization in disaster scenarios.
Each sensor type contributes uniquely to the detection process, with synergistic benefits when combined.
Further development and integration of acoustic sensing and algorithms can significantly improve search and rescue capabilities.
