Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

483
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:

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

391
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

1.9K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Virtual Work01:20

Virtual Work

1.3K
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Econometric Views (EViews)01:29

Econometric Views (EViews)

566
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

4.4K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Area of Science:

  • Medical Technology
  • Virtual Reality Applications
  • Surgical Simulation

Background:

  • Virtual reality (VR) is emerging as a surgical support tool.
  • Smartphone applications, like Google Cardboard, enable simple head-mounted displays (HMDs).
  • Outcomes of using 3D organ models in VR for medical training are not well-documented.

Purpose of the Study:

  • To investigate issues with observing 3D organ models via smartphone-based HMDs.
  • To evaluate the performance and usability of a created 3D organ model observation system.
  • To gather feedback on a novel VR observation environment for surgical case study.

Main Methods:

  • A smartphone (Samsung Galaxy S6) and Google Cardboard were used to create a simple HMD system.
  • Seventeen medical students participated in two experiments: single-observer and multiple-observer sessions.
  • Participants completed a questionnaire survey to assess the system's performance and usability.

Main Results:

  • Favorable feedback was received for the 3D dissection model, but low scores were given for visually induced motion sickness and eye fatigue.
  • Multiple observers reported clear image quality and shared understanding.
  • Displeasure arose from motion sickness, eye strain, and hardware limitations during simultaneous observation.

Conclusions:

  • A functional system for multi-person 3D model observation was established.
  • While multi-observer sessions were successful, poor smartphone performance contributed to issues.
  • Improving smartphone capabilities is crucial for a cost-effective and user-friendly 3D observation environment.
