Velocity of an Object01:18

Velocity of an Object

207
Understanding how an object moves along a path requires distinguishing between motion over a time span and motion at a precise moment. A useful example is a vehicle traveling along a straight and level path, where its position at any given time is known. The initial step in analyzing this motion is to measure how far the vehicle travels over a fixed time period. This measurement, called average velocity, is computed by dividing the total change in position by the duration over which the change...

Force Classification01:22

Force Classification

2.4K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

Classification of Neurotransmitters01:30

Classification of Neurotransmitters

5.3K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Classification of Leukocytes01:30

Classification of Leukocytes

6.0K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Classification of Illness01:17

Classification of Illness

8.8K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Classification of Bones01:18

Classification of Bones

10.0K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

  • Machine Learning
  • Medical Diagnostics

Background:

  • Attention Deficit Hyperactive Disorder (ADHD) is a prevalent neurodevelopmental disorder in school-aged children.
  • Accurate ADHD diagnosis is crucial for timely intervention and management.
  • Current diagnostic methods can be subjective and time-consuming.

  • A representative nondominated set of efficient classifiers was obtained, reflecting trade-offs between margin and error.
  • The proposed bi-objective scheme demonstrated superior performance compared to traditional classification methods in ADHD diagnosis.
  • Eliminated the need for manual hyper-parameter tuning through an automated optimization process.

Conclusions:

  • The bi-objective optimization approach offers a robust and efficient method for ADHD diagnosis using fMRI data.
  • This technique provides a valuable tool for clinicians by offering a set of optimized classifiers for decision-making.
  • The study highlights the potential of advanced machine learning techniques in improving the diagnosis of neurodevelopmental disorders.
