Spider webs and classification

 



Different spiders may spin the web according to their environment. The timing may depend on a number of factors. Some reports say that some spiders may just take one hour. Then there is the experiment where spiders were subjected to a zero-gravity environment and they took about 24 hours to complete a web.

Spider webs have so many characteristics. They have existed for 100 million years and it is very complex to study so there will be variation in the time it takes for spiders to form webs. Some spiders don’t even make spider webs.

There are four main types of webs used to identify spiders: funnel, tangled, sheet, and orb. 

Most spiders you find are not dangerous, but it’s helpful to know what is in your surroundings. You may not see any spiders, but webs are everywhere!

Funnel Web 

The most common type of spider web. Characterized by its funnel shape: narrow in the middle, widening on the sides resembling a cave opening. Funnel webs are usually found low to the ground in wooded areas or places with dense plant coverage.  Family: Agelenidae. Common name: Funnel weavers/grass spiders. Popular spider: Hobo spider.

Tangled Web 

Commonly found in dark, unused spaces around your home such as attics, corners, piles of wood and rubble, and basements. There is no definable pattern and it is often called a “cobweb”. Family: Theridiidae. Common name: Tangle-web spiders. Popular spider: Black Widow spider.

Sheet Web 

This type of web looks like a white sheet hanging between trees, in bushes, or on top of grass. The strands are woven horizontally and may be very dense. A sheet web may also look like a bowl, with the middle curving downward. This web is often used by small spiders. Family: Linyphiidae. Common name: Sheetweb/money spiders. Popular spider: Bowl & Doily spider.

Orb Web

The orb web of araneid spiders is pretty remarkable in its elegance. It's a frame supported by sticky radii, yet it can absorb the powerful impact of insects flying at full speed into it without breaking - this is due to both the properties of the silk but also to the architectural design of the web. Family: Araneidae. Common name: Orb-weaver spiders. Popular spider: Yellow garden spider

  Did you know that India has the fastest supercomputer in the world? That's right  the Param Yuva II is the fastest supercomputer in India, and it's located at the Indian Institute of Science in Bengaluru. The Param Yuva II is a high performance computing system that was developed by CDAC (Centre for Development of Advanced Computing). It has a peak speed of 20 teraflops (trillion floating point operations per second) and a theoretical maximum speed of 40 teraflops. The Param Yuva II is used for a variety of applications, including weather forecasting, climate modelling, earthquake simulation, and atomic energy research. The Param Yuva II is not only the fastest supercomputer in India  it's also one of the top 10 fastest supercomputers in the world. In fact, it's ranked #9 on the TOP500 list of the world's fastest supercomputers. So what makes the Param Yuva II so fast? Well, it has a number of features that make it one of the most powerful supercomputers in the wo

Face Recognition using Machine Learning

Image
A Machine Learning system predicts from historical data, builds the prediction models, and whenever it receives new data, predicts the output for it. The accuracy in expected production depends upon the amount of data, as the massive amount of data helped to build a better model which predicts the output more accurately. Applications of machine learning Image recognition is one of the most popular applications of machine learning. It is used to identify objects, places, persons, digital images, etc. For these images, the measurement narrates the output of every pixel in a snap. Face recognition is also one of the best characteristics that have been advanced by machine learning only. It helps to acknowledge the face and send notifications related to that to people.
