Upomas' Thought

I have just learnt some important things (though we all know these from childhood but we should try to keep in mind these things always): Wisdom is more important than wealth The biggest weakness is being afraid without any reason Don’t make friendship with fools as they could make harm to you Don’t make friendship with misers as they would leave you when you need them Don’t believe liars as they would show you dreams and then leave you without fulfilling them Keep away from backbiters as they would also backbite about you Avoid jealousy, arrogance and greed We are human beings and we may have many character defects. It’s up to us to decide if we want to be good and improve our character power. You just need to be committed to improve yourself, that’s it! Good intentions will attract good things in your life!

The dessert 'Payesh' is delicious to eat. I like it so much. Here is an easy recipe to make it. Ingredients: 1 liter milk   Powdered milk   Polao rice   Sugar Recipe: Heat 1 liter of milk over mild heat for about 40 minutes. (Pay attention whether the milk overflows. Stir to break up the foam as it forms). Mix a cup of water with 2 spoons of powdered milk and pour it into the liquid milk which is still heating and let the mixture be heated for another 20 minutes. (By this time – it can be said after total 50 minutes – wash 2 handful ‘Polao rice’ and soak it in enough water for about 10 minutes). After 20 minutes (it has been now 60 minutes total), drain the rice and add it to the milk. Keep stirring to avoid sticking of rice. Let it be cooked for about 20 minutes now. Add sugar as per your taste, stir and cook for another 10 minutes so that the milk thickens. All these take total 90 minutes and now turn off the flame. Let this be cooled and the m...

Quotes may have a good influence in life. Some quotes make us more positive about life when some help to see life from different perspective. They also have the power to revitalize our lives. I would like to include something from the movie  “Three Idiots”  – Rancho:  That day I understood that this heart scares easily. You have to trick it, however big the problem is, tell your heart, 'Pal, all is well. All is well.' Raju:  Does that solve the problem? Rancho:  No, but you gain courage to face it. So, going through positive or inspirational quotes cannot solve anything but these will give us strength to face everything. These quotes are collected from different books, movies, facebook pages, famous people etc. Here are some of them: 1.        Shift your focus from source of pain to what is desired 2.        All our problems have a solution and problems are not stop signs, th...

Engineering experiments often involve several factors and the job of an experimenter is to determine the influence of these factors on the output response of the system. Factorial experiment is an experimental strategy where factors are varied together instead of one at a time. In this article, I will just try to focus on some ideas about factorial design. Let’s begin with some useful terms which are used in factorial design:          2^2   factorial design:  Two factors, each at two levels;   2^2 or 4 runs (here runs indicate total observations).       2^3   factorial design:  Three factors, each at two levels;  2^3  or 8 runs.      Main effects:  Individual effects of each factor.            Interaction effects:  Effects when the factors interact with each other.       Replication:  Repetition of the basic experimen...

ANSYS Multiphysics 11 is used here for the analysis of Reinforced Concrete Beam. In ANSYS, all the units should be converted to a same unit and just use the value. For modeling concrete structure in ANSYS, Solid65 element type is used. This solid is capable of cracking in tension and crushing in compression [1]. In this tutorial, the use of value -1 for uniaxial crushing stress removes crushing capability and cracking of the concrete control the failure of the finite element model [2]. The shear transfer coefficient describes the ability of an open or closed crack to transfer loads. These coefficients can vary from 0 to 1, with 0 indicating a very smooth crack and 1 indicating a rough crack surface [3]. Here, open shear transfer coefficient is considered as 0.3 and closed shear transfer coefficient is 1. Uniaxial cracking stress is 3.6e6 Pa .  Elastic modulus and Poisson’s ratio for concrete and steel used here are respectively 3e10 Pa, 2e11 Pa and 0.2, 0.3. Beam dimension: Len...
