Software of unknown pedigree

SOUP stands for software of unknown (or uncertain) pedigree (or provenance), and is a term often used in the context of safety-critical and safety-involved systems such as medical software. SOUP is software that has not been developed with a known software development process or methodology, or which has unknown or no safety-related properties.

Often, engineering projects are faced with economic or other pressure to embody SOUP into their high integrity systems.

The problem with SOUP is that it cannot be relied upon to perform safety-related functions, and it may prevent other software, hardware or firmware from performing their safety-related functions. The SOUP problem is therefore one of insulating the safety-involved parts of a system from the SOUP and its undesirable effects.

SOUP is now a defined term ("Software Of Unknown Provenance") in some medical device regulations through the standard IEC 62304:2006 "medical device software – software life cycle processes". It is not prohibited to use SOUP but additional controls are needed and the risk needs to be taken into account. Specific practices to take when using SOUP as part of a medical device may include review of the vendor's software development process, use of static program analysis by the vendor, design artifacts, and safety guidance.

Soup (novel)

Soup is a 1974 children's novel by Robert Newton Peck.

Its main characters are two boys, Robert (the narrator) and his close friend Luther, better known as "Soup". It takes place during the 1930s in a small town in Vermont where the author also grew up, and deals with the daily lives of the main characters. Soup is a well-meaning, but mischievous schemer, constantly coming up with elaborate plans that invariably land him and Robert in trouble. Robert is more sensible but less wily, and frequently finds himself conned into doing Soup's dirty work. However, they are best friends and watch out for one another. Their frequent villain is school bully Janice Riker and Eddy Tacker, and Robert has a mad crush on the lovely Norma Jean Bissel.

Typical moments include the boys losing their clothes and stealing more from a rummage sale that has only women's, or Soup painting his name on a barn without permission and running the "p" over onto the corner, causing the farmer to yell "'Souf'! I'll get you 'Souf'!"

Tears

Tearing (/ˈtiərɪŋ/), lacrimation, or lachrymation, (from Latin lacrima, meaning "tear") is the secretion of tears, which often serves to clean and lubricate the eyes in response to an irritation of the eyes. Tears formed through crying are associated with strong internal emotions, such as sorrow, elation, emotion, love, awe or pleasure. Laughing or yawning may also lead to the production of tears.

Physiology

In humans, the tear film coating the eye, known as the precorneal film, has three distinct layers, from the most outer surface:

Having a thin tear film may prevent one's ability to wear contact lenses, as the amount of oxygen needed is higher than normal, and contact lenses stop oxygen from entering the eye. Eyes with thin tear film will dry out while wearing contact lenses. Special eye drops are available for contact lens wearers. Certain types of contact lenses are designed to let more oxygen through to the eye.

Drainage of tear film

The lacrimal glands secrete lacrimal fluid, which flows through the main excretory ducts into the space between the eyeball and lids. When the eyes blink, the lacrimal fluid is spread across the surface of the eye. Lacrimal fluid gathers in the lacrimal lake, and is drawn into the puncta by capillary action, then flows through the lacrimal canaliculi at the inner corner of the eyelids entering the lacrimal sac, then on to the nasolacrimal duct, and finally into the nasal cavity. An excess of tears, as with strong emotion, can thus cause the nose to run.

Instant Pleasure (album)

Instant Pleasure is Rockell's second album, released on October 10, 2000 on Robbins Entertainment. It is more pop oriented than her debut and was mostly produced by Tony Moran and Hex Hector. The album features the hit singles "What U Did 2 Me", "Tears" and "The Dance".

Tears of wine

The phenomenon called tears of wine is manifested as a ring of clear liquid, near the top of a glass of wine, from which droplets continuously form and drop back into the wine. It is most readily observed in a wine which has a high alcohol content. It is also referred to as wine legs, curtains, or church windows.

Cause

The effect is a consequence of the fact that alcohol has a lower surface tension than water. If alcohol is mixed with water inhomogeneously, a region with a lower concentration of alcohol will pull on the surrounding fluid more strongly than a region with a higher alcohol concentration. The result is that the liquid tends to flow away from regions with higher alcohol concentration. This can be easily and strikingly demonstrated by spreading a thin film of water on a smooth surface and then allowing a drop of alcohol to fall on the center of the film. The liquid will rush out of the region where the drop of alcohol fell.

Wine is mostly a mixture of alcohol and water, with dissolved sugars, acids, colourants and flavourants. Where the surface of the wine meets the side of the glass, capillary action makes the liquid climb the side of the glass. As it does so, both alcohol and water evaporate from the rising film, but the alcohol evaporates faster, due to its higher vapor pressure. The resulting decrease in the concentration of alcohol causes the surface tension of the liquid to increase, and this causes more liquid to be drawn up from the bulk of the wine, which has a lower surface tension because of its higher alcohol content. The wine moves up the side of the glass and forms droplets that fall back under their own weight.
