Types of Materials:
Bricks
1. Hollow Blocks
2. Green Bricks
Making & Use
Differentiate green bricks for the materials they are constructed and there are several proposals (in line or already in progress) of bricks with different components:
Coal ash: This was an idea of a civil engineer, Henry Liu, in 1999, with a double environmental benefit. With this material the bricks are obtained at 212 degrees in 10 hours and take advantage of 45 million tons of the waste generated by coal power plants.
Hemp and straw: This brick and green has been used by Spanish companies. Despite the apparent fragility of the material hardness is similar to conventional ones. They have the disadvantage of being more expensive but well isolated from the outside temperature. This represents a savings of energy expenditure for heating and air conditioning, so that pays the price soon.
Used plastic and peanut shells: ecological bricks of this material are a creation of the Experimental Center for Economic Housing in Argentina who says they are tough, lightweight insulation and economic. In addition to producing energy savings possible recycling of waste for production.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Understanding Inductive Bias in Machine LearningSUTEJAS
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
HEAP SORT ILLUSTRATED WITH HEAPIFY, BUILD HEAP FOR DYNAMIC ARRAYS.
Heap sort is a comparison-based sorting technique based on Binary Heap data structure. It is similar to the selection sort where we first find the minimum element and place the minimum element at the beginning. Repeat the same process for the remaining elements.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

What Is Expanded Polystyrene?
Expanded polystyrene is widely
used material because of its
number of benefits. Its a plastic
foam material that has amazing
properties because of its
structure such as extraordinarily light
and buoyant, and a good insulator
against heat and sound. It can be
Used as a building material or a
Design element, and can be molded
into many shapes for a number of
household uses as well.
3. Website:- http://ecclestons.com/expanded-polystyrene-construction-products.htm
How It Is Made?
Basically it is made up of two chemicals
Which are called ethylene and benzene.
When these two chemicals combine with
Each other a new compound is produced
Which is known as styrene. The
styrene is then treated with other
chemicals which cause the styrene
molecules to polymerize, or to group
together in long chains. And many other
reactions make at last the polystyrene
for us.

Advantages Of Polystyrene
Another important advantage of
expanded polystyrene, especially
for products like disposable cups,
is that it is very cost-effective.
Manufacturing polystyrene foam
requires much less energy than
the manufacture of paper-based
alternatives. Additionally, it has the
potential to create much less waste
than paper
