Classifying Matter by Composition

Classifying Matter by Composition

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

Classifying Matter by State

Classifying Matter by State

Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Sleep-Wake Cycles

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

How Data are Classified: Numerical Data

How Data are Classified: Numerical Data

Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

Area of Science:

Fluid dynamics
Machine learning
Biomimicry

Background:

Unsteady flows contain valuable information about their sources.
Aquatic organisms extract flow information using local sensing.
Traditional flow analysis requires global flow field data.

Purpose of the Study:

To train neural networks for classifying flow patterns using local vorticity measurements.
To assess the network's accuracy in distinguishing specific vortex wake types.

Main Methods:

Utilized neural networks for flow pattern classification.
Employed local vorticity measurements as input data.
Focused on vortex wakes generated by an oscillating airfoil.

Main Results:

The neural network successfully classified different vortex wake types.
Accurate distinction between 2S, 2P+2S, and 2P+4S wake patterns was achieved.
The network identified key features characterizing each wake type.

Conclusions:

Local sensory measurements combined with neural networks offer a powerful alternative to traditional flow analysis.
This approach has potential applications in understanding biological fluid dynamics and flow sensing.
