Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

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.
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
- **Efficient Use of Bandwidth**: TDM all

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.
2. Bay Area
Housing Crisis
The Bay Area has added nearly two jobs
for every housing unit built since 1990.
This imbalance has been further
exacerbated by widening gaps between
high- and low-income households as
well as deficits in affordable housing
production. These conditions have
contributed to core regional challenges
like traffic congestion, affordability,
displacement, and homelessness.
3. EPA: Low Income
Homeownership
The challenges of suburbia are
compounded in low-income,
predominantly immigrant communities
like East Palo Alto, where families are
slowly being priced out of their own
neighborhoods. Feeling the desperation,
many homeowners are finding their
own solutions, converting structures
like garages into living areas for multiple
families. Done without going through
the city’s approval process, however,
and this creates unsafe environments
that don’t meet legal housing
requirements.
4. Forced into
Suburbia
One major barrier to the production of
more housing is the significant portion
of urban land that is zoned for R-1
single-family residential development.
Suburban communities have strong
incentives to preserve their property
values and sense of neighborhood
identity, forcing local and state politics
into gridlock when in comes to policies
allowing for incremental upzoning.
5. The low-hanging fruit of affordable
housing is in the spacious backyards of
many R-1 parcels. Accessory Dwelling
Units (ADUs) are 300-700 sf structures
with their own bathroom and kitchen
that could easily utilize undeveloped
space.
Can we make it cheaper and easier for
homeowners to build an ADU in their
backyards?
Vision: Accessory
Dwelling Units
6. Economic Benefits
As smaller units that integrate directly
into suburban environments, ADUs are
the most affordable way to increase
safe and convenient housing exactly
where it is needed. They will increase
the value of the properties for those
who install them on their lot, and the
increase in property tax will provide
much-needed revenue stream for
chronically under-resourced city
governments. The construction will use
local labor, and with more residents to
fill in empty space, local commercial
businesses will see more customers as
well.
7. Social Benefits
ADUs can be rented out to students or
couples. Empty nesters can move into
the ADUs and rent out their main homes
to larger families. ADUs can even be
paired with supportive service programs
to temporarily house the homeless.

8. Environmental
Benefits
ADUs by design have a smaller
environmental footprint and limit the
continued sprawl of suburban growth
by densifying existing residential
neighborhoods. This can reduce traffic
by placing people closer to their places
of work, and add revenue to local
governments by increasing the use of
regional public transit. ADU projects can
also enable much-needed retrofits to
existing single-family homes to reduce
energy and water consumption, with
the possibility of the ADU addition
having a net-zero impact on resource
consumption of the parcel.

9. Policy Barriers
A major barrier to ADU development is
in some unintentionally restrictive local
policies: zoning restrictions such as
minimum lot size for ADU eligibility,
building codes that uniquely challenge
small additional units, and an onerous
permitting process made worse by
oversubscribed city staff. The informal
evidence of this is the many
homeowners that choose to implement
ADU projects illegally, leading to safety
issues and code enforcement that
residents perceive as antagonistic.
10. Policy Solutions
Technology can play a critical role in
alleviating the permitting bottleneck by
streamlining digital submittals and
review of ADU projects, as well as
increasing ADU viability by clearly
demonstrating the impact of zoning
changes to city staff. We have been
working with the City of EPA, San
Mateo County, and other partners to
develop such tools.
11. Decision Barriers
Even under favorable policy conditions,
our neighborhoods may still not have
the information or incentives to initiate
and complete ADU projects. For
individual — and especially working —
families, the time investment required
to understand and plan an ADU without
technical expertise is simply too large.
Much of the critical information that
influences the ADU decision
fundamentally depends on site-specific
analysis, which is often expensive and
hard to organize.
12. Decision Solutions
Technology can also play a critical role
in nudging homeowners to initiate the
ADU process, whether by disseminating
compelling stories about benefits of
ADUs, empowering website users with
property-specific information about
ADU options and costs, or guiding them
through the full permitting process
automatically online.
13. Construction
Barriers: On-site
Even if policy and decision barriers were
fully alleviated, Bay Area neighborhoods
would still struggle to scale ADU
production at the current costs and
complexities of residential construction. The
materials and labor cost of on-site
construction average over $200/sf, meaning
that a 500 sf ADU is likely to cost over
$100,000, beyond what many homeowners
can afford. In addition, placing a detached
ADU in a backyard can be challenging given
narrow lot size, obstructions to cranes (for a
modular unit) like trees and powerlines, and
narrow, winding streets full of neighbors
who would be impacted by construction
operations.
14. Solution:
Panelized ADU
Our solution combines the benefits of
on-site and off-site industrialized
construction through a panelization
method. Flat, standardized sections of
floors, walls, and roofs would be built in
a controlled and optimized factory
setting, shipped by truck to the site,
conveyed through a track system
through the side yard to the backyard,
and then assembled using lightweight
tools.
15. Design Benefits:
Constructability
A panelized system unlocks many
single-family sites that are too narrow
or obstructed to receive a full modular
unit craned over the main house. Every
R-1 lot can be guaranteed to have a side
yard width of at least 3 feet, which
would be the minimum design
condition for our conveyance system.
The result is an accelerated assembly
process in the backyard with large
prefabricated elements that reduce the
noise and traffic impacts on the
neighborhood while still maintaining a
critical role for local labor.
16. Design Benefits:
Customizability
Panelized ADUs allow for customizable
floor plans that meet the particular
needs of homeowners in terms of ADU
size, number of bedrooms, and finish
style, all still based on a small number of
unique parts. An online web tool could
allow homeowners to search for their
address and visualize the largest ADU
that can legally be built in their
backyard, enabling as much quality
housing as possible with each
development.
17. Design Benefits:
Cost Reduction
Standardized panel sections can be
manufactured in a factory at economies
of scale for less cost than on-site
custom construction. Shipment of
panels is also more efficient than
shipping full spatial volumes, akin to
IKEA’s strategy with furniture. The end
result would be ADUs that fall
consistently under $100,000 in
construction cost, and potentially
including permitting fees if the
approvals process is also streamlined
using a digital design platform.

18. Alternative Use:
Attached ADU
ADUs do not have to be standalone
backyard units: they can also be
conversions of the garage or other parts
of the existing home, or be installed as
additions to the existing home. These
could potentially use the same basic
panels, leading to even more affordable
options for expanding capacity of single
family lots.
19. Project Proposal:
Panelized ADU
We propose the completion of a
prototype panelized ADU from design
to operation in order to document the
full process and demonstrate the
feasibility of a <$100,000 ADU project.
The key steps include:
1. Identify a recipient and select an
optimal panelized ADU design
2. Produce full construction
documentation along with
permit approvals
3. Identify a factory, or site that
simulates a factory, and
prefabricate the panels
4. Deliver and assemble the ADU
20. Precedent:
Stanford Solar Decathlon
Stanford completed a similar
demonstration project when it competed
in the 2013 Solar Decathlon. With the
support of the Carpenter’s Union and
other sponsors, students designed,
engineered, and constructed a 1000 sf
net-zero home on Stanford campus. They
also disassembled the house into
modules for shipment to a competition
site in Southern California. Stanford’s
Sustainable Urban Systems Initiative
could help to administer similar formats
for engagement, providing a simulated
factory site, student participation, and
other useful academic resources.
21. Outcomes:
Demonstration Story
This prototype ADU project would yield
many important outcomes, including a
powerful story around co-production of
knowledge between academic, public,
private, and social sector stakeholders
which can disseminate through existing
networks and programs to the broader
Bay Area audience. Such a
demonstration could attract much
larger support and grassroots
participation in many other
communities.
22. Outcomes:
Open-Source Documentation
This project would also include
extensive documentation of the full
process and lessons learned, including
open-source drawings, data, tools, and
qualitative assessment from
stakeholders. This would be useful to
practitioners, residents, and other city
officials for years to come.
23. Outcomes:
Building Science Research
Given an academic partner, the
prototype ADU project would also have
the co-benefit of serving academic
research, particularly based on
instrumentation of the ADU with the
ability to track heating/cooling,
energy/water consumption, and human
comfort. The manufacturing process
could be approached from a theory-
driven background in industrialized
construction processes, and students
could conduct a life cycle assessment of
the entire project process to track
holistic environmental and economic
impacts.
24. Resource Needs
For this project to be successful, it needs the following key
resources:
1. Eligible site and receiving property owner
2. Partner city with staff support to streamline
permitting process
3. Factory or site for prefabrication process
4. Subject-matter experts to help with design and
construction
5. Monetary and in-kind donations
