Why does ice crack when added to a beverage?












2












$begingroup$


I think most people have experienced this, but while pouring a beverage over ice I noticed the ice cracked upon pouring a beverage with anti-freeze properties.

After

My initial thought was some sort of thermal shock due to the cooling from dissolving the ice and the resultant rapid cooling locally, but I know that this also occurs when other beverages such as various flavored carbonated sugar water products are poured on ice which do not depress freezing as much. So then What would cause the ice to crack?

    Not related to the question, just fun fact: declassified KGB memos from 1970s on how to recognize a spy listed that the one is most likely going to add ice to its beverage and prolong the drinking process, whereas soviets wouldn't bother with ice and drink the glass in one gulp :D

I believe the ice cracked due to residual strains from freezing. Since ice freezes from the outside inward and it expands as it freezes, that as the inner water freezes, it imparts a tensile force on the surrounding ice (like the opposite effect of tempering glass). As the warm liquid removes ice, the cross sectional area under tension decreases while the tensile force remains the same, causing an increase in stress. Once the stress reaches a certain point, the ice fails to counter the tension mechanically, causing the cracks.

            How to label and detect the document text images

            Image
            1 $begingroup$ This is what I mean as document text image: I want to label the texts in image as separate blocks and my model should detect these labels as classes. NOTE: This is how the end result should be like: The labels like Block 1, Block 2, Block 3,.. should be Logo, Title, Date,.. Others, etc. Work done: First approach : I tried to implement this method via Object Detection, it didn't work. It didn't even detect any text. Second approach : Then I tried it using PixelLink. As this model is build for scene text detection, it detected each and every text in the image. But this method can detect multiple lines of text if the threshold values are increased. But I have no idea how do I add labels to the text blocks. PIXEL_CLS_WEIGHT_all_ones = 'PIXEL_CLS_WEIGHT_all_ones' PIXEL_C...
