Dr Rieux in Albert Camus’ “The Plague”

by
A physician stands on a glowing divide between two opposing worlds: a dark quarantined industrial city with masked medical staff on one side, and a fiery militarized landscape with rows of soldiers and an authoritarian flag on the other.

The Author Albert Camus (1913–1960) was a French writer-philosopher and a key figure in existentialism. Born in Mondovi, Algeria, Camus began his philosophy studies in Algiers.

Inside Dicom

by
A masked technician in an early 20th-century laboratory examines a long strip of medical film beside a large mechanical projector, surrounded by analog control panels, surgical instruments, and a glowing circular image on the wall.

In a previous blog post, we explored how to read the content of a DICOM file, including its numerous tags. These tags provide insights into the study type, characteristics, and all relevant patient and study information. Now, we’ll focus on the most crucial tag—the one containing the images. A typical study can include anywhere from … Read more

“The Scarlet Plague” by Jack London

F statistic

by
A wide, painterly vintage seascape shows a solitary scholar standing on a rocky cliff beside books and a globe, looking out over three small islands in the sea. The islands are clearly separated, while the waters around them vary from calm and circular to rough and turbulent, creating a poetic visual metaphor for comparison and variation.

Both one-way ANOVA (Analysis of Variance) and repeated measures ANOVA employ the F statistic as a tool to evaluate the null hypothesis that there are no significant differences between the groups being studied. Numerous other statistical tests utilize the F statistic, including regression, Levene’s and Bartlett’s tests for homogeneity of variance, MANOVA, ANCOVA, Wilks’ lambda … Read more

Early 20th-century doctor in a white coat examines a seated woman wrapped in a blanket inside a modest rural clinic, with wooden furniture, medicine bottles, an oil lamp, and snow-covered windows.

Following our general introduction to the matplotlib environment, let’s explore the types of graphs this Python library can produce. Among the most commonly used graphs for data presentation are: Histograms Histograms primarily illustrate the distribution of a continuous variable. The data is divided into uniform intervals (bins), and the frequency of each bin is represented. … Read more

Matplotlib (1)

by
A formally dressed man in early 20th-century attire stands in a grand, softly lit gallery, studying large framed charts and illustrated panels, with vaulted ceilings, tall windows, and a warm sepia-toned historical atmosphere.

Python offers several libraries for creating professional graphs, but Matplotlib stands out as the foundation upon which many others are built. Often referred to by its alias “plt,” Matplotlib enables users to generate complex, element-rich graphs as well as multiple visualizations. Another popular library, Seaborn (alias “sns”), functions as an extension of Matplotlib and requires … Read more

Character Encoding

by
Elderly bearded man in early 20th-century attire examines a framed tablet covered with archaic symbols inside a worn hospital ward, surrounded by an iron bed, anatomical charts, glass bottles, and antique medical instruments.

Character encoding is the process of assigning a unique number to each character, enabling computers to exchange data in a standardized and unambiguous manner. Various encoding systems have developed over time and across different regions. These systems often lack compatibility, have space limitations (and consequently character limitations), and may use the same encoding for different … Read more
