Quality Control01:05

Quality Control

3.0K
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Control Systems: Applications

1.2K
Electrical engineering plays a pivotal role in our daily lives, with control systems at the heart of many applications, from home appliances to sophisticated space shuttles. Control systems manage and regulate the behavior of devices and processes, ensuring they function safely, correctly, and efficiently.
In modern vehicles, control systems manage various functions to enhance performance and safety. The steering wheel and accelerator are primary inputs in a car's control system. The...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

488
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Electron Carriers01:24

Electron Carriers

92.2K
Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be oxidized). They play an essential role in energy production because cellular respiration is contingent on the flow of electrons.
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

Electron Affinity03:07

Electron Affinity

43.8K
The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion).

Quality Assurance01:19

Quality Assurance

2.7K
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Area of Science:

  • Medical Physics
  • Instrumentation
  • Quality Control

Background:

  • Traditional quality control (QC) in medical physics relies on various specialized devices.
  • Portable and accessible QC tools are needed for efficient field applications.

Purpose of the Study:

  • To develop a portable QC application on a tablet-type consumer electronic device (CED).
  • To integrate thermometer, barometer, angle gauge, and range finder functionalities.
  • To assess the accuracy of measurements made by the developed application.

Main Methods:

  • The QC application was programmed using Java and OpenCV.
  • Temperature and pressure sensors of the CED were compared against standard devices over 30 days.
  • An angle gauge was developed using the CED's accelerometer, measuring roll and pitch angles.
  • A range finder was created using the CED's camera and image processing for distance measurements.

Main Results:

  • Temperature and atmospheric pressure measurements showed minimal differences (mean ± SD: -0.07 ± 0.25°C and 0.05 ± 0.10 hPa).
  • Angle measurements had a mean difference of -0.17 ± 0.87° (excluding 90°).
  • Distance measurements demonstrated high accuracy with a mean difference of 0.01 ± 0.07 mm.

Conclusions:

  • The developed portable QC application is accurate and reliable.
  • It can serve as a substitute for conventional measuring instruments.
