Project-1: An Intelligent Fire Detection and Warning System Under Home Video Surveillance for Garments Factories in Bangladesh

Devastating fire is a great concern in home monitoring system. Though there are many systems with state-of-the- art in fire detection but false signal is still a challenge to avoid. Fire detection and its information using image processing and information technology respectively can be a great hope to reduce devastation of fire mishaps. In multistoried buildings like a garments factory, fire can be originated or smelled from one unit of the building or floor but same type of alarm will put people into confusion, which can lead to a sudden panic. A lack of proper alarming approach in fire alarm system can be a reason of stampede death in a crowded multistoried building like garments factory in Bangladesh. Fake fire is another concern in conventional fire alarm system. In this project, an intelligent fire detection and warning system under home video surveillance is aimed in order to detect fire from video camera data and warn the concerned people accordingly. The system’s design will undergo a low computational time taking fire detection approach using RGB color space and it will warn the people dynamically than conventional alarming unit. The system will be able to cope up with the present conventional fire detection approach under security surveillance system. The proposed fire detection approach will be tested under different scenarios to confirm the accuracy of the system.

Required Qualifications: The potential candidate is expected to have engineering/physics or similar/relevant technological background to work in this project. He/she must have a high passion to contribute to a real-world problem with their skills and knowledge by realizing the current scenario of fire detection and alarming system in garments industries in developing countries like Bangladesh. Skill on image processing is also desirable.

Project-2: Design and Implementation of a Novel MPPT Based Synchrounous Buck Converter for Solar-Powered Fishing Trawler Installed in Chittagong Region of the Bay of Bengal

In Bangladesh, approximately 3900 square miles of entire length is surrounded by 700 rivers including tributaries. Around 770,000 inland and 510,000 marine fishermen survive in this country, whose income entirely depends on fisheries. Bangladeshi fishermen mainly use trawler for fishing purpose in sea and river. Those trawler boats require electric power at night for fishing and lighting purposes. Currently, in a trawler, electric power is supplied by a battery which is charged through a dynamo synchronized with trawler engine. These dynamos require diesel to serve electric power. In this project, a novel MPPT-based solar power system for fishing trawler is aimed to reduce fuel consumption. This project aims a method of extracting the maximum current from the PV cell to quickly charge a lead acid cell battery during its “bulk” or constant current charging phase. A PID controller will be attempted to ensure that the DC-DC buck converter maintains a constant current output regardless of the charge level of the battery as long as it is in the bulk charging stage. The simulation and hardware to be implemented through the algorithm to optimized the commercially available 24V PV cells.

Project-3: Design and Implementation of an Intelligent Solar Photovoltaic Energy Management System for Developing Countries

The objective of the proposed project is to design and implement of an intelligent photovoltaic energy management system to meet up the automatic energy distribution recording and playback calculation and providing necessary information to concern people. The system will undergo the solar photovoltaic energy efficiency variability analysis based on country’s current scenario leading to the large scale energy generation from renewable sources.

Project-4: Non-invasive/Minimally Invasive Blood Test for Newborn/Neonate Parameters

Problem Statement: Blood drawing or collection from newborns for diagnosis purpose or even for routine screening, is one of the major challenges associated with newborn/neonate critical care in developing countries due to lack of skilled person, insufficient amount of blood in a newborn’s body for collection, and many other reasons. For different blood parameters to test; it requires a lot of blood from newborn body and often from different locations which make it very difficult to get sufficient amount of blood and even if it gets enough blood, the tiny newborn body has to go through lot of sufferings and pain. The whole procedure is also emotionally very difficult for the persons who draw/collect blood from newborns. Therefore, to make this whole blood collection process convenient and less/no painful, a minimally invasive (if not fully non-invasive) procedure is badly needed.

Description: In this project, we expect to develop a low-cost technology to make the procedure of blood drawing from newborns a more convenient, less painful and easy-to-use. Since there are many parameters or components of blood to test, not every parameter may be possible to measure non-invasively, but few parameters such as blood glucose, or similar components of blood can be possible to measure with a non-invasive technique using some kind of harmless light-wave or imaging or using sound/ultrasound wave. The parameters that are not possible to measure non-invasively, we expect to measure them by using minimal amount of blood such as a typical commercially available glucose meter which requires a single blood-drop to measure the glucose level in blood.

Although, it may not be possible to develop the proto-type of the desired technology in 2-3 months, but we would like to study the current laboratory procedures for blood test in the local diagnostic centers and then to analyze different blood components about their responses to different light/sound wave for possible non-invasive measurements. If not non-invasive, then we would try to find out a way to measure with minimal amount of blood requirement. We would like to continue the project until we develop the desired proto-type.

Required Qualifications: The potential candidate is expected to have engineering/physics/mathematics or similar/relevant technological background to work in this project. He/she must have a high passion to contribute to a real-world problem with their skills and knowledge by realizing the current scenario of neonatal heath care in developing countries.

Project-5: Real-time Imaging/Monitoring of Vein during Blood Draw/Collection and Canula Insertion for Infants

Problem Statement: One of the major challenges associated with infant blood test during blood drawing or collection from newborns for diagnosis purpose or during canula insertion is locating the vein accurately. Sometimes, even with skilled hand, accurate locating of the vein becomes challenging and hence insertion of needle is carried out several times with no luck. Therefore, if any device is available that can non-invasively image the vein in real-time for locating the vein accurately would be very helpful for both the patients and caregivers.

Description: In this project, we aim to develop a real-time monitoring device/technology that can image the vein to locate its position accurately. In order to do that, we may require a light wave to incident upon the body and can see through the reflection/refraction image in a LCD display attached to a microcontroller based embedded system which can be programmed as per requirement.

Required Qualifications: The potential candidate is expected to have engineering or relevant technological background to work in this project. Experience to work with microcontroller-based embedded system would be an added advantage, but not mandatory. He/she must have a high passion to contribute to a real-world problem with their skills and knowledge by realizing the current scenario of neonatal heath care in developing countries.

Project-6: Low-Cost Digitization of Saline Dropper Set

Problem Statement: In developing countries like Bangladesh, most of the people seek in-patient medical treatment from Govt. medicals, where the ratio of clinicians to patient ratio is very low including the lack of proper medical resources. One of the most faced problems in Govt. or local medicals/clinics is the proper monitoring of the saline drops going into patient’s body. The available saline dropper sets are manually controlled by nurses, but often the drop count goes wrong which may cause serious harm to the patients, especially when it is required to maintain a certain drops/count for some nutrition elements such as calcium, potassium, etc. being injected to body. The over-injection or under-injection of such nutrition drops not only fails the treatment goal but also may cause serious harm to patient body. Therefore, a digital monitoring device for accurately maintaining the dose and automatic alarm system to notify if the drop-count goes wrong is extremely necessary.

Description: We expect to develop a low-cost microcontroller based system to sense the saline drops, count it and regulate it through the user-given value while the current and expected count will be displayed in real-time on a LCD display.

Required Qualifications: The potential candidate is expected to have engineering or relevant technological background to work in this project. Experience to work with microcontroller-based embedded system would be an added advantage, but not mandatory. He/she must have a high passion to contribute to a real-world problem with their skills and knowledge by realizing the current scenario of neonatal heath care in developing countries.

Project-7: Automated Drone For Providing Medical Services In Bangladesh

Problem Statement: Providing prompt, effective and pointed medical care is essential for saving lives, especially in the case of medical emergencies. In such situations, time is of the essence and it becomes imperative to provide rapid emergency medical services (EMS)to patients to save lives and to minimize any kind of irreversible tissue damage. In the context of Bangladesh where there is lack of medical services in extensive rural areas across wide swathes of the country, incessant and unpredictable traffic jams around the clock in megacities like Dhaka, an accurate shortage of ambulances and first aid response services in most rural and urban areas and high cost of medical treatment, it is important to be able to deliver emergency medical services to a patient at their residence within minutes from the time of reporting of the medical emergency.

Description: In this project, we are proposing to design and develop an EMS drone that will be capable of carrying emergency medical devices and supplies to patients forgeneral complaints and also in emergency situations. For example, the EMS drone can be designed to carry a miniaturized version of a defibrillator that can be used to reestablish normal contraction rhythms in a patient having dangerous arrhythmia or in cardiac arrest. The desired EMS drone is expected to also be capable of carrying emergency medicines 24 hours a day to the doorsteps of patients. It is desired to have the proposed EMS drone be constructed with minimum cost and with greater flight speed than normal aerial robots for providing potentially fast and life-saving medical services to patients in a minimum period of time. To this end, we have already built aerial robots for different civilian uses, e.g., live videos streaming for aerial videography, supplying goods from one place to another, etc. Specifically, for the EMS drone project we have already designed an octocopter drone with autonomous features and expect to embark upon the test flight in the coming weeks.

Ongoing Research and Desired Qualifications for Candidate: We need to develop a more precise and accurate aerodynamical design of the drone for greater efficiency, design a payload carrying case, and a light weight defibrillator suitable to be stored inside the EMS drone. We are also looking for ways to increase the controlling distance of the EMS drone to upto 50km in radius and develop a way of charging the EMS drone using natural resources, for e.g., by fitting the EMS drone with solar panels. We would be very interested in working with a graduate student to help us in our stated goals. Proficiency in mechanical engineering with good sense of aerial robotics designing AND/OR proficiency in biomedical engineering to help us out with designing a light weight defibrillator are greatly desired.

Project-8: Design and Implementation of Remote and Virtual Laboratory to Enhance Classroom Teaching for Undergraduate Engineering Students

Good understanding of theory is largely dependent on experimentation or practical realization. But abstract and complex nature of the classroom lecture arise difficulties to relate theoretical analysis with the practical results. As a result, the learning curve gets steeper for most of the students. This urges for the enhancements in all aspects of engineering education. Enhancement of the learning experience for the students, by the incorporation of virtual and remote laboratory based framework in classroom teaching is one of the potential methods.

With this framework instructor can relate the theoretical knowledge with the practical one. To concrete the theoretical analysis, virtual lab is used where instructor can perform the simulation multiple times by changing different parameters and observe the corresponding output without any restriction. After completing virtual lab based study, remote lab can be accessed to demonstrate the practical experiments and its results where many influences are present which is often hard to simulate. Both of these labs are equally important because combining these two labs together instructor can provide a better understanding and learning environment to the students in the classroom.

Previously, a number of discrete virtual and remote laboratory have been implemented in many universities around the world including developing countries. However, individual virtual and remote labs are failed to provide expected results as each of this lab has its own limitation. Virtual systems are important as it does not cause any real damage when any kind of incorrect parameters are put to the systems. But it fails to provide complete practical scenario. Remote labs provide real time experience but it takes only predefined or limited parameters from the users.

Because of the above mentioned limitations, researches have been conducted to build integrated remote and virtual laboratories. As a part of research, few numbers of integrated virtual and remote labs have been proposed or implemented in many universities. But these implemented models have been designed with expensive and complex infrastructure which may not be feasible for implementing in many developing countries. Besides, safety and security issues are not well studied for these systems. So in order to implement this potential framework in every engineering institution especially in developing countries, a significant amount of research work is required to design a cost effective, robust and well secured virtual and remote laboratory facility.

Project-9: Design and Implementation of Android App-based Wearable Real-time Body Temperature Monitoring and Alert System for Children with Risk of Febrile Convulsions.

Project Description: Many children in our country suffer from febrile convulsions or seizure during their early childhood days (including neonate to infant) due to various clinical reasons. Each time a convulsion or seizure occurs, it damages around 10,000 neuron cells per second and thus poses a great risk to the development of brain which eventually leads to different developmental delays, disabilities or diseases including physical, mental and cognitive such as Epilepsy, Cerebral Palsy, and Autism. As the body temperature increases during fever, the probability of having convulsion also increases. Thus the parents or caregivers always need to be alert in order to monitor the child’s body temperature or fever. However, such fever measurement is often done manually by either analog or digital thermometer which is not feasible when it is required to monitor the temperature at a continuous rate with storing the previous temperature values as well. In addition, the child is often not co-operative (or irritated) to allow measuring its body temperature again and again by placing the thermometer sensor under the armpit. Thus it is a great need to develop a wearable patch type temperature sensor which can be placed on the body surface of the kid and it is not irritating but it keeps record and sends the temperature data wirelessly to a Smartphone where the Android App will show the temperature reading from time to time. Moreover it should send an alarm if the body temperature crosses a certain threshold value (e.g. risk of fever) to the user (i.e. parents or caregiver) of the phone.

Research goals and objectives: First we expect to simulate the proposed system and then make a proto-type on a PCB for such temperature monitoring system connected to a Smartphone App via wireless technology (e.g. Bluetooth). Then we would like to integrate the whole circuitry in one small package which can be wearable. The required miniature version of the whole system may require more time. Thus we would like to continue it in the 2nd year for further improvement.

Required Qualifications: The potential candidate is expected to have engineering / physics / mathematics or similar / relevant technological background to work in this project. He/she must have a high passion to contribute to a real-world problem with their skills and knowledge by realizing the current scenario of renewable energy system in developing countries.

Project-10: Optimizing the Efficiency of Solar Cells Using Patterned Nanostructures

Project Description: Photovoltaic (PV) cells are important devices that can be used to convert photons into electrical energy. However, the cost of current PV devices needs to be significantly reduced and their efficiencies need to be substantially enhanced to enable large scale implementation of PV cells as sources of clean electrical energy. Surface plasmonpolaritrons (SPP) in metallic nanostructures in close proximity to a Si substrate can lead to enhanced optical absorption and improved energy conversion efficiency in amorphous silicon thin-film PV devices. Optimization of this phenomenon requires a detailed characterization and understanding of the parameters that govern the underlying physical mechanisms. This research will explore the relationship between energy conversion efficiency in thin-film Si solar cells and the type of metallic nanoparticle, the size of the metallic nanoparticles, and the distance between neighboring metallic nanoparticles in a periodic array of the metallic nanoparticles deposited on top of the Si substrate. Such plasmonic metal nanoparticles can also be incorporated into the Si substrate in different other configurations to increase in the generated short circuit current density (JSC).

Research goals and objectives: i. Determine the optimal size, shape and orientation of the plasmonic metal nanoparticles to use with the Si substrate to maximize the solar cell efficiency. ii. Determine the optimal configuration of coupling the plasmonic metal nanoparticles to the Si substrate to maximize the solar cell efficiency. iii. Determine way to combine plasmonic metal nanoparticle with other patterned nanostructures to maximize the solar cell efficiency.

Project-11: New Approaches in Smart Grid and Power Failures

Project Description: Blackouts are among the last remaining major challenges in power systems. It is proposed that we use publicly available data to find general patterns and trends about the largest blackouts. Analysis will then be performed on selected data points in order to find interesting trends and patterns like whether or not advancement of technology has minimized the total number of large blackouts. Furthermore, the correlation between number of people affected and total restoration time of the blackout is investigated and interpreted in a detailed manner. The research proposes to explore different types of causes that trigger initial disturbances in the power system, which eventually leads to a cascading effect that cause widespread power failures. Recommendations or areas of improvement have also been suggested.

Research goals and objectivesA. Developing new methods for reducing blackouts based on above approach. B. Investigate new approaches in Biomedical engineering

Project-12: Developing a NAO Application for Robot Handwriting Using Inverse Kinematics

Project Description: With the rapid evolution of humanoid robots, it is now possible to have humanoid robots in households and educational institutions in order to assist with different household tasks, chores, etc as well as aid in teaching and learning. However, the method of interaction with these robotic systems is through speech and gestures, with most of the robot’s feedback being verbal responses or physical simulation. The aim of this project is to research a new method of humanoid robotic feedback that involves handwriting. The rapid growth of humanoid robot applications in industry and educational institutes places it at the forefront of many new ideas and research for extension and improvement of the current capabilities of humanoid robots. The goal of this project is to develop handwriting capabilities into a NAO robot. The developed application will enable the NAO robot to hear a word from its operator, and implement handwriting techniques to write out the word itself without assistance. The areas of focus for this research are speech recognition and inverse kinematics in humanoid robots. This method of robotic communication will be particularly effective and useful for people with disabilities such as hearing impairment or loss, since they are not be able to understand the verbal feedback from robots. It could be helpful to people with full or partial paralysis, so that they will be able to use humanoid robots for assistance in day-to-day activities that require handwriting. It could also provide a new platform for learning and interaction for children with autism.

Project-13: Design and Implementation of an Integrated Remote Engineering Laboratory for Undergraduate Students

Project Description: For engineering students, laboratory classes play a significant role as hands on experiment can enhance student’s learning ability and creates interest in the course. But lack of resources such as lab instrument, space, and strict timeslots make it harder to provide desire learning experience. This scenario is more prevalent in most of the developing countries where most of the educational institutions do not have privilege for sophisticated laboratory or industry standard instruments which hinders the technical growth of students. On the other hand, even if limited resources exist most of the students end up as spectator as being in a large group. Several universities have already developed remote laboratory in recent years. For example iLab of MIT, the British Open University, the Swiss Federal Institute of Technology, NetLab of the University of South Australia, among others. However, these labs are designed with highly expensive and complex infrastructure. So these models may not be feasible for implementing in developing countries. But implementation of remote laboratories is still in demand especially in the developing countries like Bangladesh. The objective of this research is to design and implementation of an Integrated Remote Engineering Laboratory for Undergraduate Students to provide them a real lab like environment where they are able to operate real instruments and devices. This remote lab would provide an opportunity for students to perform their experiment individually, understand what they are doing and relate the theoretical knowledge with practical experience.

Project-14: Studies on Technical Feasibilities of Solar Powered Farm Machineries Suitable for Bangladesh

Project Description: The economy of Bangladesh heavily depends on agriculture. The agricultural activities of the country have been mechanized over the last few decades. Most of the farm machineries are based on diesel engine like; water pump, tractor, rice howler etc. In the new era when people around the world are very much concern about the green house gas and climate change, clean technologies should be developed in farm machineries. Solar photovoltaic panels could be used as energy source for powering an electric motor. The motor could be used as prime mover for all agricultural activities instead of diesel engine. The technical feasibility of the project would be performed by constructing a prototype and testing it in the field.

Project-15: Studies on Economic Feasibilities of Solar Powered Cooking in the Rural Household of Bangladesh

Project Description: Depletion of Natural Gas and increasing price of LPG, burning wood, coal etc, are now the main menaces for cooking purposes in Bangladesh. On the other hand, inefficient burning of wood, charcoal, agricultural wastes and animal dung etc, generate smoke and emits ozone gasses. This results in global warming and health issues due to inhalation of the smoke. Because of a good solar irradiation pattern, a solar powered conduction cooker can minimize this burden from the nation. Solar photovoltaic panels could be used as the main source of energy for cooking, although it is one time investment, the initial high cost of the solar panels would be the main obstacle for adopting the technology. Over the last few years the price of solar panel drastically declined and still the trend is decreasing, therefore, it is hoped that cooking using solar panels would be realistic in the near future. The purpose of the project is to study the economic feasibility of solar powered cooking by comparing with the conventional cooking practices.

Project-16: Design and Construction of a Smart Electric Wheel Chair for the Mobility Impaired People

Project Description: This project is intended for the people who are mobility impaired, for a variety of reasons, incapable of using an ordinary wheelchair. A low-cost robotic wheelchair can assist the operator of the chair in avoiding obstacles, going to predestinated places, and maneuvering through doorways and other narrow or crowded areas. These systems can be interfaced to a variety of input devices, and can give the operator as much or as little moment by moment control of the chair as they wish.

Project-17: Development of an Android-based portable ECG monitoring system for rural/remote areas of Bangladesh (UG only)

Project Description: Cardiac disease is one of the leading causes of death in the developing world and is the leading cause in the developed world according to WHO. The electrocardiogram (ECG) is the most common method for diagnosing cardiovascular diseases. Prior heart attacks and common abnormal heart rhythms can easily be diagnosed using the ECG. The process usually involves attaching a number of electrodes to the arms, legs and chest of the patient to detect the electrical impulses from the heart. However, in rural/remote areas of our country, sufficient medical facilities (such as ECG machine) are absent for which most of the people suffer from under-diagnosing. The aim of this project is to develop a low-cost portable ECG monitoring system with 3-lead electrodes that can be monitored on a smart-phone with vital diagnostic parameters or so called ECG characteristic points (PQRS) such as heart-rate, HRV, pulse rate, etc. to help the doctors to diagnose of any abnormal hearth activity.

We expect to simulate the proposed system and then make a proto-type on a PCB with Arduino board for such ECG monitoring system connected to a Smartphone App via wireless technology (e.g. Bluetooth).

Project-24: Radio Interferences (Generated from Mobile Voice Call) Removal from Invasive Neural Recordings (UG or Graduate)

Project Description: The wireless in-vivo neural recordings (sampling frequency, Fs is approx. 40kHz) have been found to be severely corrupted by radio interferences while any voice call from a GSM based cellphone is being made. After band-pass filtering the recording from 300 Hz to 5 kHz, in time domain analysis, many spike-like interferences/artifacts (with amplitude higher than the typical neural spike) are observed along with original neural spikes. This makes the detection of actual neural spikes a great challenge. After frequency domain analysis by comparing a dataset without such radio interference (no voice call was made that time) with a dataset having such interference (during voice call made), it has been observed that the radio interferences involve frequency ranging from 150 Hz up to few kHz. The confusion regarding this findings is that how it's possible for the recorder to pick up radio frequency in the MHz range emitted by the typical GSM mobile phones ( ~900 MHz or ~1800 MHz) while its (I.e. recorder) highest achievable frequency is 20 kHz since Fs = 40 kHz ( according to Nyquist theorem). One possible answer is these interference are sub-harmonic frequencies of original GSM frequency which is picked up by the neural recorder after down-conversion of frequency ( or by demodulating the GSM signal) and seen in frequency domain analysis in the figures as attached in the email.

If this hypothesis is true about sub-harmonic interference then how to handle such interference to get rid of them. Is there any literature on Subharmonics theory or it's mathematical model? E.g. in typical 50/60 Hz power line noises / interferences we know that 50/60 Hz frequency is the fundamental one and its integer multiple frequencies are the higher harmonies. But in this particular case we see frequencies ranging from 80 Hz to few kHz which seems to be the sub-harmonics of 900/1800 MHz GSM signals. But seeing at the so-called subharmonics the frequencies don't seem to be following any particular mathematical ratio. So it';s really important at this moment to find out the relevant theory of subharmonic interference (if there is any).

Project-25: Motion Artifact Removal from Ambulatory EEG (Graduate only)

Project Description: EEG recording is often contaminated with different types of artifacts/interference. Specially it gets worsen while the recording is performed in an ambulatory environment where the subject is free to move around; which eventually causes lots of motion artifacts. The purpose of this project is to reliably identify and reduce such motion artifacts without distorting the desired EEG information. We would like to use online physionet.org database of motion artifact contaminated EEG data for validating the removal algorithm and observe its performance.

Methods: Wavelet Transform, Adaptive Filtering, Empirical Mode Decomposition
