Solid Waste Management in Gazipur, Bangladesha989work
This study examined the behaviors and practices around household solid waste management among microcredit borrowers in two urban areas of Gazipur, Bangladesh. Through surveys and focus groups, the researchers analyzed participants' knowledge, attitudes, intentions, and practices regarding waste management, and how socioeconomic factors influence these. While most participants understood the health and economic benefits of proper waste management, their behaviors did not consistently reflect this. Higher education and income were associated with better waste management practices. However, additional income from microcredit loans was not being used to improve household waste management. Improving waste management in these areas will require incentives or systemic changes beyond just providing additional income.
This study summarizes the evolution of farming systems and livelihood dynamics in Northern Chin State, Myanmar over the last few decades. It finds that shifting cultivation, primarily of maize, had been the major livelihood but is changing towards more rice-based semi-commercial farming with the development of terraces and lowland paddy fields. Terracing started in the 1960s but mass adoption only occurred in recent decades due to NGO assistance. Lowland paddy provides staple rice for 5-7 months while shifting cultivation alone provides maize for only 3-6 months, requiring other livelihood combinations to meet food needs. Increased population has shortened fallow periods in shifting cultivation, reducing yields. The assistance of development organizations like
Chin State has been characterized among all states and regions of Myanmar as the highest poverty gap ratio, highest occurrence of food deficits, poor road connectivity on steep mountain ridge and narrow valleys, low population density but lowest percent availability of cultivable lands and high percentage of waste and scrub lands, adherence to the shifting cultivation system, lack of rural based industries, and higher rate of out migration.

"Capture" in a lambda expression - C++
A lambda expression is an anonymous, inline function. It is used to create a local function, mainly for passing as an argument to a function call or as a return value.
"Capture" makes variables in the local scope available for use in the body of the lambda expression. By default, variables are captured by value. Variables can be captured by the reference as well. Also, there are syntaxes which allow passing all the local variables and objects into the lambda expression.
What is CAD? What is CAE? and What is CAM? Did you hear about those three terms before? If so, what is the dedicated software, and how do they differ?
The first two letters of each word, "CA" stands for "Computer Aided", which means all three systems are created to help the user to achieve their goals with the power of computers.
In complete words, "D" stands for Design, "E" stands for Engineering and "M" stands for Manufacturing.
Even if you feel all these three terms are similar, that is not. Each one has its objectives.
In geometries, this word is used for shapes that lose their characteristics or that are not generated correctly. Degeneracies can arise due to issues in geometry (parametric) or topology. When parametric space is incompatible with the real world of the geometric model, degeneracy is created. Degeneration can happen not only for edges but also for curves, and faces. Degeneracy is not this kind is not harmful in and of itself. These shapes can be used in Boolean operations, and mesh. Degeneracies that happen after a Boolean operation will cause problems and at that time, we need to be aware of its existence.
Degenerate boundary is an incomplete or zero-area loop, or an incomplete or zero-volume shell.
An operator is a symbol designed to operate on data.
They can be a single symbol, di-graphs, tri-graphs or keywords.
Operators can be classified in different ways.
This is similar to function overloading
The basic meaning of the buffer is a memory block of a computer that acts as a temporary placeholder. Buffer is used in different fields and the most common examples are video streaming and RAM. In programming, a software buffer is denoted by a place that keeps data before the process is started. That will be fast rather than data writing in a direct way. People tend to use “buffer” when data is moving around. The reason is that the data will be temporarily placed in a buffer and move to the final destination afterward. When the receiving data rate is different from the processing data rate, buffers are very useful. You will get to know this while video streaming.
Open CASCADE Technology (OCCT) is a C++ library that is designed for the production of domain-specific CAD/CAM applications. The most important feature of this library is it is free. But the applicability and capacity of this library are huge. Many open-source CAD/CAM products are based on this. With the help of a huge community and development team, developers, users, researchers, and commercial product developers can use it for different industrial applications, research, and many more.
The mechanism is an assembly of machine components (Kinematic Links) designed to obtain the desired motion from an available motion while transmitting appropriate forces and moments.
Four bar linkage is a simple planer mechanism which has four bar shaped members. Usually it has one fixed link and three moving links and four pin joints.

Computational and experimental investigation of aerodynamics of flapping aero...Lahiru Dilshan
Renewal interest on the exploitation of flapping flight motions to attain high propulsion efficiency of air vehicles is inspired by the aerodynamics of birds’ and insects’ flights. The flapping characteristics can be majorly used to develop micro aerial vehicles (MAV) as this is a lucrative method to generate lift and thrust simultaneously. In this project, the variation of the flow properties and the thrust generation of an airfoil in a flapping (plunging) motion, is evaluated using both computational and experimental methods. The NACA 2412 airfoil was selected for the study and, the computational method was carried out using an inviscid flow model and computational fluid dynamics (CFD) simulations, simultaneously to obtain and compare the variation of properties.
The inviscid model was developed using conformal mapping and potential flow theories, and it is capable of producing results for any arbitrary aerofoil. Steady-state results were compared and validated in both CFD and inviscid flow modelling as the computational framework along with flow visualisation and force sensing as the experimental framework. The validated CFD and inviscid models have been developed to produce a plunging motion to the aerofoil and obtain the variation of drag and lift coefficients with time. The experimental setup was designed to obtain the forces acting on the airfoil, and the flow characteristics were visually observed using a flow visualization technique. The force calculations were done through a developed and optimized load cell arrangement. The developed smoke flow visualisation technique is capable of successfully capturing streamline patterns, flow separation regions. These results were compared along with wake development between computational and experimental models. The Level of agreement and limitations of each method have been discussed in this report.
Experimental and numerical stress analysis of a rectangular wing structureLahiru Dilshan
Structures of an aircraft can be categorised as primary structural components and secondary structure components. Primary structure components are the components which lead to failure of the aircraft if such component is failed during the flight cycle. Secondary components are load sharing components in an aircraft but will not pave the way to catastrophic failure.
Designing aircraft structures should follow several strategies to assure safety. For that, there are three main methods used in designing and maintenance procedures. First one is the safe flight, which an aircraft component has a lifetime. That component is not used beyond that limit and should replace though it is not failed. The fail-safe method is another one that redundant systems or components are there to ensure there is another way to carry the load or do necessary control. The final one is the damage tolerance which measures the current damages are within acceptable limit and carry out the main functions until the next main maintenance process.
To determine the safety of a structure component load distribution, stress and strain variation, deflection can be used as parameters to make sure that component can withstand maximum allowable load with safety factor. There are several techniques used to get accurate results as numerical methods, Finite Element Method (FEM) and experimental methods. In the design process, those three steps are followed in an orderly manner to ensure the safety of an aircraft.

Transient three dimensional cfd modelling of ceilng fanLahiru Dilshan
Ceiling fans are used to get thermal comfort, especially in tropical countries. With the increment of the usage of air conditioners, the emission of CO2 is increased. But ceiling fans are a limited solution, that saves much energy compared to air conditioners. Ceiling fans generate a non-uniform velocity profile, so that, there is a non-uniform thermal environment. That non-uniform environment does not imply lower thermal comfort, that will give enough thermal comfort with low energy cost by air velocity. Hence, there will be difficulties of analysing with simple modelling techniques in that environment. So, to predict the performance of the ceiling fan required more accurate models.
The accurate model of a ceiling fan will generate complex geometry that makes difficulties for the simulation process and requires higher computational power. Because of that, there are several methods used to predict the performance of the ceiling fan using mathematical techniques but that will give an estimated value of properties in the surrounding.

Human factors in payload safety of fighter aircraftsLahiru Dilshan
Human factors are prominent in military aviation safety. Human error is a major cause of aviation incidents and accidents. When transporting military payloads like weapons and dangerous goods, many individuals and roles are involved to ensure safety. These include packers, preparers, handlers, inspectors, loadmasters, pilots, and more. Thorough training is required for anyone involved in transporting hazardous materials. Safety mechanisms on weapons like missiles and bombs help prevent accidental detonation and ensure they are guided accurately to their targets. The roles of multiple individuals and safety systems work together to manage risks involved in carrying military payloads.

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

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

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.
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.

1 Abstract
Waste management has become a major issue in Sri Lanka. Due to the unorganized
collection and disposal of waste, the country is facing a crisis. Piles of garbage becoming
bigger, requiring more space day by day, causing many health issues, social problems and a
serious long-term environmental crisis.
The main purpose of this project is to filter the garbage and use them for other recyclable
options through various recyclable facilities and make a profitable outcome.
In this project, methods have been developed to minimize the amount of garbage by
filtering plastics, paper and metal, ultimately leading to a reduction of more than 50% of the
existing amount of garbage. The process was developed through investigating general waste
composition and to deliver filtered material in the recyclable status.
By imposing new regulations for the collection and management of garbage, the work load
in the filtering plant can be mitigated and the waste can be directly fed to the recycling plants
delivering a positive effect on income, solving related issues.

5 Overview
The waste generation rate has been significantly increasing throughout the past decade,
and is expected to increase rapidly, further in future due to population growth and urbanization.
Statistics show that, annual waste generation is expected to increase from 70% by 2050, which
is 3.4 billion tons and average solid waste generation per day is 7000MT and the western
province accounts for 60% of the total.
Residents in Sri Lanka, especially the urban poor, are severely affected by unsustainably
managed waste and around 80% of waste is dumped at huge lands. So, due to lack of proper
waste collection procedure, considerable percentage of waste is burnt openly or often disposed
in unregulated dumps. These unethical practices result in severe safety, health and
environmental consequences.
Reducing and eliminating adverse impacts of waste materials on nature and human health,
would support economic development and superior well-being of human life. There are six
functional disciplines associated with solid waste management program.
1. Waste generation
2. Onsite handling, storage and processing
3. Waste collection
4. Waste transfer and transport
5. Waste processing and recovery
6. Disposal
The Central Environmental Authority (CEA) initiated a 10-year waste management project
named ‘Pilisaru Program’ in 2008 for a “waste free Sri Lanka by 2018”. Eventually, project
was failed due to ineffective and inconsistent practices. No proper waste management program
could cure eye sores in Bluemendhal, Meethotamulla, Karandeniya, Kolonnawa areas. In 14th
of April 2018, the burst of the Meethotamulla garbage mountain killed 30 people, destroying
more than 100 houses. Even after the Meethotamulla incident, no significant action was taken
by the government, until today.
Initial capital cost to establish an effective waste management system is estimated to be
significantly higher, according to the past data obtained from waste management projects in
other countries. Therefore, proper funding becomes a priority of a waste management project.
Afterwards, maintaining and operating that would require efficient integrated systems which
are sustainable and socially supported.

6 Context
Establishment of a solid waste management plant consists of several stages. At the initial
stage, design inputs of the project should be given by segmenting waste management
requirement and most critical design inputs should be identified.
Biodegradable waste can be identified as mostly produced waste type in Sri Lanka.
‘Other’ waste product type which occupies 17% of the chart may include electronic waste,
metallic waste etc.

7 Project Description
7.1 Aim and objectives
Aim
Establish an effective solid waste management system for Sri Lanka which suits to the
social and economic behaviour of the country and implement a solid waste management plant
to contribute to the country’s economy.
Objectives
• Initiate an efficient solid waste collecting system by evading infirmities in the
traditional system.
• Establish new waste recycle centres
• Increase the contribution and involvement of the public to the project
• Evaluate options of profit making
7.2 Project Description
1. Waste collection and transfer system
2. Waste storage system
3. Waste processing system
4. Waste disposal system
7.2.1 Waste collection system and transfer system
Implementation of waste collection centres, would encourage the public to support in
maintaining the cleanliness. A systematic approach will be implemented in order to raise the
awareness of households, about the importance and benefits.
The transportation of waste from households to the waste collection centres will be
done by a well-established garbage collection vehicle service. Effective transportation methods
and schedules will be implemented, evading infirmities within the traditional system.
7.2.2 Waste storage
Selection of a land for storage without affecting the health of the neighbourhood is utmost
important. Proper ecological, financial, and technical feasibility studies should be done, before
implementing these storage systems.
Waste storages should be separately maintained as unprocessed, temporary, and treated..
After separation, there would be a separate storage for hazardous waste. Necessary conditions
9. Project Clean Lanka
4 | P a g e
for the filtered waste would be implemented within the storage, to maintain its recyclable state
until it’s delivered to the recycling centres.
7.2.3 Waste processing system
In this section, waste would be sorted and further processing steps will be followed
including washing, removing, detailed categorization and compressing. Compression
(shredding, pelletizing, pressing and packing) is done to reduce the cost of transportation.
Separate ecological, technical and financial feasibility studies will be carried out, so that
would help to finalize the filtering process upon factors as selected location, type of land,
available expertise, technology and allocated budget.
7.2.4 Waste disposal system
After filtering, the remaining waste will be collected separately and systematically
disposed through composting, landfills and incineration chambers, depending upon the content
of the waste. The content will be decided through visual inspection and technical reports, and
then directed to the relevant disposal method.
Since, the filtered waste will be washed and cleaned separately in the final process,
Generated waste water should undergo proper treatment, sedimentation and filtering to reduce
the impact to the environment.
After recovering the waste to the highest possible extent, remaining non-recyclable, non-
hazardous waste can be used to landfills.
7.3 Legal status
As this project is based on waste sorting and handling, the factors should meet the
requirements of National Environment Act No. 47 of 1980 (as amended by amendment act
no.56 of 1988 and as amendment act no.53 of 2000).
The process of disposal of waste should comply with current environment impact
assessment of Gazette (Extra ordinary) No. 722/22 of 24th
June 1993. Noise level should
maintain at the boundaries as mentioned in the Gazette (Extra ordinary) No. 924/12 of 23rd
May 1996.

7.4 Waste Collection System Feasibility analysis
7.4.1 Financial feasibility
Automated collection may not be feasible for the country at the moments due to the higher
financial requirement.
Even though it’s convenient, it’s practically impossible to collect garbage daily. We can
prioritize the level of requirement and proceed with the collection as daily, thrice a week and
twice a week. Usage of common bins can help to further plummet the cost of handling.
When collecting frequency is reduced, more transportation capacity will be essential.
Waste transportation being a major expense in waste collection, should be considered.
Door to door collection would be the most expensive method, but due to the effectiveness
and the convenience of the majority, the service will have to be utilized to provide the optimum
service.
Cleaner cities will result in a good recognition, ultimately adding a positive effect in the
tourism industry, which benefits in attracting investors for the growth of our economy.
7.4.2 Social feasibility
Even though, daily garbage collection will have a better public convenience inside
households, excessive resources being used to collect small amounts of garbage, will
compromise the efficiency of the system.
When the collected frequency reduces, people tend to dump garbage illegally, due to the
available personal storage capacity. Improper waste disposal, leads to blocked drains, increased
contaminated water bodies, increased infections and diseases.
Door to door collection is the most convenient and effective method for the public, but
economic feasibility study should consider, waste pooling sites as next best option.
Residential waste collection frequency can be reduced to twice a week. But the
commercial, industrial waste collection will have to be done daily, due to the higher amount of
waste accumulation. Public ideas should also be considered to further optimize the system.
7.4.3 Ecological feasibility
Minimal health risks would arise with daily waste collection, but it will carry the most
usage of fuel in transportation, and traveling waste trucks in streets would cause bad odor.
Usage of common bins is environmentally sound, but possibility of negative impacts
exists, if not properly managed. The waste collection stations should be safely designed, since
11. Project Clean Lanka

the risk of typhoid, cholera, diarrhoea, infections and skin diseases, exists to the
neighbourhood.
Solid waste management deserves a bigger focus, especially as a country who depends
largely on tourism, in order to protect natural beauty of water bodies, forest reserves.
7.5 Filtering plant Feasibility analysis
Sorting is acted as a filter between collection and disposal and most materials can be
recovered. The sorting configuration varies from simple manual sorting to complex automatic
multi-process sorting line.
The configuration of the plant depends on planned input and output, level of technology
and financial available. Also, there are two different conceptual approaches as positive sorting
and negative sorting. Both of these methods are used in sorting process.
Mixed MSW has less value compared with sorted waste. There are three sorting
configurations used in sorting plants.
7.5.1 Technical feasibility
Several techniques can be used in the sorting process as moving beds, drums and screens,
air separation, etc. After sorting MSW, further processes can be carried out to sort plastics

again. That will determine the quality of the material output. These are relevant technologies
which can be used in waste sorting.
Apart from the sorting machines, plant will need movers to move, load and unload waste
within the operating area. The conceptual sorting plant diagrams are in the annex 2.
7.5.2 Social feasibility
In the sorting plant, the safety of environment and employees should be considered. There
should be good ventilation system, odor, noise, vibration and litter control. Potential for
exposure to hazardous material should be managed and safety equipment should be used during
the operating hours. There should be appropriate facilities for site staff and workers including
showers, hand basins, drinking water supply, etc. Rotting garbage within the yard should be
avoided by “first in first out” practice. With the sorting plant, the infrastructure on the particular
area will be developed, creating many new jobs for the country.
7.5.3 Financial feasibility
There are several facts which need consideration, when deciding on manual and automatic
sorting. These two methods have unique features, and both can be utilized to obtain the
maximum outcome from the project.

The quality control should exist at the end of the sorting process to ensure that materials
meet the demanded technical specification so that lab testing facility should be initiated, which
can be used to future research and development processes.
There are several phases in construction of sorting plant. During planning, costs are
divided into site selection, design activities, preparation of tender document and procedures.
Construction phase includes land purchase, process equipment, supporting equipment,
maintenance, labour, environmental protection and others. Main operational costs are
associated with labour, energy, resource consumption, maintenance, insurance, monitoring and
control.
Considering these effects, conceptual design of sorting plant is in annex 2-figure 3.

7.6 Waste disposal plan feasibility analysis
7.6.1 Waste selling
Sorted waste is categorized as biodegradable, plastic, paper and carboard, glass, e-waste,
metal and other. There is a sufficient market to sell these piles and have the potential to import.
This process should be implemented through Central Environmental Authority. There can be
bilateral arrangements between processor and the buyer so that standards can be implemented
and that cause to guarantee the sales of products. Remaining biodegradable waste can be used
for Bio gas generation and compost production.

8 Project monitoring and control
Most of the parts of this project is guided by Central Environmental Authority (CEA) and
will also be responsible for project monitoring and controlling.
The quality of the sorted waste is monitored using lab reports. A dedicated maintenance
section is appointed for emergency maintenance cases. Description of maintenance procedures,
employee training, health and safety provisions, emergency procedures should be well planned.
Efficiency is monitored using Key Performance Indicator (KPI).

9 Market Analysis
9.1 Potential customers
There exist recycling plants within the region, which will be major target customers for
the project.
9.2 Market targets
It is suggested to gradually increase the covered area and to cover the whole Colombo
district within a year.
9.3 Demand for solid waste generation and disposal
Western province is responsible for more than 50% of waste production and Colombo is
the largest waste generated district in Sri Lanka (Colombo Municipal Council, 2012).
According to the figure 3, it can be predicted that the amount of solid waste collection would
keep on increasing in Colombo district.

9.4 Public survey
A research was carried out successfully using a sample of 390 people, mainly consisting
students from southern and western provinces.
Only 40%, are handing their garbage over to the urban council and 3rd
party collectors,
and over 40%, collect all their garbage and burn. This shows that the waste collected frequency
in relevant areas are not sufficient.
Only 40% is making compost which can easily be further improved, through raising
awareness in the public. Over 50% are willing to sort their garbage and hand over.
Majority thinks that the garbage collection is a problem, and over 95% knows that this
issue will lead to cause illnesses. This sets up a perfect opportunity to introduce a proper waste
management system (annex 4).

10 Budget
10.1 Total project budget
10.2 Project financial feasibility analysis
With the consideration of forecasted profit loss analysis and forecasted cash flow
statements, Net Present Value (NPV) and Internal Rate of Return (IRR) values were estimated.
A positive NPV of 1,638,719.60 is estimated with a IRR of 21.51% which is greater than
CoC of 12% which can be concluded that the project is financially feasible.
Simple payback period is estimated as 4 years 10 months and discounted payback period
is estimated as 6 years 8 months which is financially profitable.
