PBL on Energy Conservation with Rainwater HarvestingS K
This document proposes a system called Energy Conservation on Rainwater Harvesting (ECRH) that generates electricity from rainwater. The system would include modifying roof designs to make them slanted to easily direct water flow. Water would be collected and sent through an impulse turbine connected to a generator to produce electricity, which would be stored in an energy storage device. Theoretical calculations estimate that a 6-minute heavy rainfall could generate enough energy to charge a cell phone battery. The system provides a cheap, small-scale way to harvest renewable energy from rainwater while also collecting water for non-potable uses.
This document proposes using waste water from tall buildings to generate small-scale power through a micro hydro turbine system. Waste water from upper floors of a building would be collected in a storage tank located at a suitable head height. The stored water would then be released at a steady rate to drive a micro hydro turbine, generating electricity. For a sample 25-story building housing 50 families, the system could produce an estimated 17 kilowatt-hours of power per day by utilizing waste water from the upper 30 units. While challenges include setting up the storage tank and turbine maintenance costs, the system provides a renewable and pollution-free way to recover energy from waste water with minimal initial investment.

Small scale generation by harnessing the wind energyeSAT Journals
Abstract Generating electricity from wind has been centered around the rotation rotating windmill in which rotating shaft coupled to the generator used to generate electricity. Other sources such as solar power hydropower, thermal power, wind power are used for generating electricity in kilo watts and megawatt but there is no such kind of application which can generate electricity on sub 100watt scale. So as to generate electricity on small scale and to provide cheap source of energy for lighting the houses in remote where there is no other sources are available. And to generate a power source that can be constructed with the help of local material and if problem occurs that can be fixed by the local people. About 2% of global electricity production comes from wind-powered generators. Their capacity has doubled in the past few years. In some countries it is more popular than solar energy because it is cheaper on a cost per watt basis. However, for powering small devices there has been minimal activity to harvest energy from the wind. This is because conventional electromagnetic wind turbines require rotating fins and gearing which adds bulk, and they become less efficient when scaled down. Key Words: Harnessing, Wind Energy, Rotating Shaft

This document summarizes a study that models a reinforced concrete beam-column joint under cyclic earthquake loading. The study conducted nonlinear static and dynamic analyses of the joint model. Under nonlinear static analysis, the joint was subjected to cyclic earthquake loading. Under nonlinear dynamic analysis, the joint was subjected to three real historic earthquakes. Crack pattern analysis identified the worst cracking scenario. Seismic analysis identified critical response times when maximum forces, displacements and stresses occurred. The model sustained all earthquakes, but failed during the third cycle of cyclic loading. Crack size and location varied between earthquakes. Cracks developed and increased with additional loading cycles, leading to failure. The study compared results to previous work and found reinforcement bar size significantly impacts load capacity.

The methods used in the evaluation analysis includes coefficient of correlation (COC), hypothesis testing (Z-test for Estimated Cost, Z-test for % Mark-up and T-test). The evaluation
was conducted on various construction company in accordance to sectors A to D. It has been concluded that the % mark-up percentage had a minor effect on the win or loss of the contract bid between
different sectors. This research has found that (1) the null hypothesis cannot be rejected at the 5% significance level the samples showed no significant proof to which of the sectors is more successful in winning bids than other, (2) the regression analysis indicated that as
the estimated cost increases the % mark-up decrease for all sectors, (3) the t-test illustrated no significant difference existing between the mean estimated cost and mean % mark-up between contracts won
and contracts lost for all sectors, since the value of t Stat was less
than t-critical two tailed the null hypothesis cannot be rejected and (4) there is a stronger correlation existing for the successful bids than
unsuccessful.

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.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEMHODECEDSIET
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM

turbine and wide buckets. Another major aspect which should
be taken into consideration to successfully produce suf icient
amounts of electricity is the rainy region. As this system relays
completely on the amount of water fall, higher amounts of
water fail means higher amounts of generated electricity. The
water wheel turbine along with the generator including the
cables and their ixtures can be easily installed as long as the
main water wheel turbine its in the water ditch. Moreover,
the system can be easily de-installed in case it is not working
properly or in the case of few waters falls in the region of
installation. On the other hand, the system is considered very
economical suf icient and cost effective on the long-term
run. Furthermore, Figure 1 shows the whole process of the
proposed design to generate eco-friendly green electricity
from rain fall water.
In the opinion of the author of this short review, this
proposed design has many advantages to replace the current
pollutant sources of electricity such as fossil fuels. In addition,
this new technique of generating electricity can be a great
solution for poor countries with high rates of water fall.
Moreover, this system can be used on two scales. Where the
irst scale is the individual scale for personal direct use of
electricity for home. This could be conducted by individuals
whom has water ditches constructed in front of their home.
They can apply for approval license from the local municipally
to install water wheel turbines in the water ditch within their
home circumference. In this case a small electrical generator
may be itted to store additional electricity for personal home
use for later. On the contrary, the second scale is through
private companies or governmental agencies. They can install
this system on wide scales perhaps throughout the country
to generate clean electricity and distribute it to the public for
a small amount of fee. Also, this could be a great method to
save money from paying the monthly electricity bills. Below
are the main advantages of the proposed design to generate
eco-friendly green electricity from rain fall water:
• Permanent source of electricity with regular main
tenance.
• Cheaper than casual sources of electricity.
• Environmentally friendly design system for producing
green electricity.
• The system can be installed and de-installed easily.
Finally, the author of this short review paper hopes that
this new system of generating eco-friendly electricity from
rain water will be used on small and big scales in the near
future.
