Specific Heat01:16

Specific Heat

67.8K
The specific heat capacity of a substance refers to the energy required to increase the temperature of one gram of that substance by one degree Celcius. Specific heat capacity is often represented in calories (cal), grams (g), and degrees Celsius (oC), but can also be expressed in joules (J), kilograms (kg), and Kelvin (K), among other units.
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or...

Density, Specific Weight, Specific Gravity and Compressibility of Fluid01:27

Density, Specific Weight, Specific Gravity and Compressibility of Fluid

1.7K
Density, specific weight, specific gravity, and compressibility are fundamental properties of fluids. Density is the mass per unit volume, characterizing the mass of a fluid system. It influences buoyancy, pressure, flow dynamics, viscosity, thermal conductivity, and sound propagation. For instance, in pipeline design, accurate density measurements ensure that the pipeline can handle the fluid's mass.
Specific weight represents the weight per unit volume and is calculated by multiplying...

Cell Specific Gene Expression01:58

Cell Specific Gene Expression

16.6K
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...

Applications of Logarithms01:28

Applications of Logarithms

292
Logarithmic functions are powerful tools for simplifying the mathematical representation of phenomena involving exponential changes. Their ability to convert multiplicative relationships into additive ones is especially valuable in various scientific and engineering contexts. One notable application of logarithms is measuring sound intensity, specifically through the decibel (dB) scale used in acoustics.Sound intensity levels vary over an extensive range, from the faintest audible whisper to...

Area of Science:

  • Software Engineering
  • Human-Computer Interaction
  • Digital Health

Background:

  • Usability is crucial for the adoption and effectiveness of mobile health (mHealth) applications.
  • Existing literature on mHealth usability lacks a standardized, reusable framework for development and evaluation.

Purpose of the Study:

  • To propose a software requirements catalog for usable mHealth applications.
  • To develop an audit method for evaluating mHealth app usability based on the catalog.

Main Methods:

  • Literature review to identify key usability sources for mHealth apps.
  • Catalog organized using ISO/IEC/IEEE 29148:2011 standard and SIREN methodology.
  • Audit method created and applied to evaluate Samsung's S Health application.

Main Results:

  • The proposed catalog and audit method were successfully applied to evaluate S Health.
  • The S Health app received a usability score of 83%, with identified flaws.
  • Specific usability issues noted included navigation patterns, startup experience, empty screens, and writing style.

Conclusions:

  • A reusable usability requirements catalog and audit method can effectively identify flaws in mHealth applications.
  • Improving navigation, startup, content presentation, and writing style are key to enhancing user experience in mHealth apps.
