No full textThis thesis is submitted in partial fulfilment of the requirements for the degree of Bachelor of Science in Electrical and Electronic Engineering, 2018.Catalogued from PDF version of thesis.Includes bibliographical references( page 57-62).Presently there is a globally growing demand across all industries for small and portable electronic devices which feature Internet connectivity. This is largely due to their ease of use provided by robust interoperability and feasibility in almost any scenario. Internet of Things (IoT) can be a great tool to achieve this goal of connecting people and devices everywhere all the time. IoT is a network of various types of devices connected together to seamlessly data transfer without any computer or human interaction. IoT can be defined as a network consisting of many small sensor nodes whose main purpose is to collect data from surrounding environment and then forward to the base station. Firstly, we develop a theoretical model of physical layer of Wireless Sensor Network (WSN). Next, we derive the energy efficiency expression and solve the optimization problem of energy efficiency under the constraint of Packet Reception Rate (PRR). Two application perspective of IoT such as biomedical and smart home appliance has been proposed. Modeling of WSN using MATLAB to perform simulation of real human body have been analyzed. A model of smart juice maker has also proposed here which can be controlled from mobile apps.Md. Monwar Jahan ChowdhuryMd. Fazlul Haque Jesan.Md. Saiful Islam MilonB.

No full textThis project report is submitted in partial fulfilment of the requirements for the degree of Bachelor of Pharmacy, 2018.Catalogued from PDF version of project report.Includes bibliographical references (page 51-53).Postpartum depression is one of the major categories of maternal disorder right after the delivery process. Women experience a serious phase of vulnerability during that period. Though postpartum depression has been found to have an effect on a large number of women after child delivery in developing countries, no authentic estimation to understand the immensity of this disorder in Bangladesh. Women in our country might not speak out but this does not excuse the actual fact that the surrounding system is not ready to concentrate on this matter yet. Additionally, most of us do not acknowledge the symptoms and ignore it as a negligible matter. The aim of this study was to elucidate the current scenario of this disorder in Bangladesh, compare the severity of postpartum depression among housewives and working women while determining the existence of different support groups that might play a significant role to overcome this issue.Shanta IslamB.

potential customers has been the focus of past research. Traditional approaches have faced
many negative responses, now to make business profitable the new marketing strategy is
live campaigns. With the growth of location-based social networks collecting data of user
mobility and popularity of places has recently become attainable, but not without analyzing
to find the optimal location and time for live campaigns with greater accuracy. In this paper,
we study the predictive power of various machine learning and mining features on finding
suitable location for live campaigns through the use of a dataset collected from Foursquare
in New York. We selected 10 candidate areas where the data was preprocessed according
to the feature, a score is computed on the candidate areas to do live campaigns based on
the features using most suitable algorithm with the accuracy. The results with Random
Forest and Decision Tree are shown at the end of the report. Lastly, our proposed model
shows how performance varies when using different features and predicting the suitable
locations for live campaigns. We achieve 88.25% accuracy in Decision Tree regression
model and an accuracy of 88.48% and 70.04% in Support Vector Machine (SVM) and
Random Forest respectively.Tahrat TazrinMohiuddin Md Abdul QudarKazi Zainab KhanamB. Computer Science and Engineerin

A comparative study of power sources for base transceiver station
No full textThis thesis is submitted in partial fulfilment of the requirements for the degree of Bachelor of Science in Electrical and Electronic Engineering, 2018.Catalogued from PDF version of thesis.Includes bibliographical references( page 48-52).Base Transceiver Station is considered as the heart of mobile telecommunication system. Millions of phone calls, SMS and enormous number of data is being sent and received in every second through these BTS all over the world. Therefore, BTS are the devices which need to run 24/7 without being disturbed by any sort of electric crisis or shortage. Bangladesh is not fully compatible to meet the growing electricity demand of the whole country. Although it varies from day to day, on an average we predicted there are two hours of load shedding period in every distribution line of entire country. Therefore, it requires 24/7 electricity supply to all the BTS of all operators. Our concern is during the off grid period. It is found that all the operators use diesel generators for the off grid time. Our target is to compare the feasibility of using alternative power sources to minimize the cost of the system, minimizing carbon emission and reducing the dependency on the fossil fuel. Firstly, we have analyzed the previous and recent data of diesel, solar and fuel cell power sources. A new we model is proposed to combine the sources with backup of diesel generator which can minimize the cost and fulfill our target. We also analyzed the future of carbon emission which our proposed model can reduce after a certain period of years.Md. Pavel MahbubSyed Minhajul AbedinSarwar Ali ArmanMd. Mahmudur RahmanB.

Rapid biological synthesis of silver nanoparticles from Cymbopogon citratus extract and evaluation of its antimicrobial properties
No full textThis thesis is submitted in partial fulfilment of the requirements for the degree of Bachelor of Science in Biotechnology, 2018.Cataloged from PDF version of thesis.Includes bibliographical references (page 35-38).It has been well known for many years that silver Nanoparticles (NPs) are toxic to microorganism and can potentially kill them. They can also provide solution to different technological and environmental problems such as energy conversation, tailor-made medicine, cancer treatment, waste water treatment etc. Nanoparticles can be synthesized in many different ways such as physical and various other chemical methods. These methods are expensive and use many different toxic substances which make them difficult to scale these methods for mass production. In recent years it has been found that plant molecules can perform the same reduction reactions necessary for the production of nanoparticles but in a much more efficient way. Here, green chemistry were employed for the synthesis of silver nanoparticles (AgNPs) using leaf extracts of Cymbopogon citratus (Lemon Grass). Effects of different parameters such as temperature, pH and volume of plant extract were also tested using their absorbance pattern at different wavelengths. The total formation of the AgNPs was observed visually with a color change from yellow to brownish-black. UV-visible spectroscopy was used to monitor the quantitative formation of silver nanoparticles which showed a signature peak in absorbance between 400 and 500 nm. Changing different parameters had a significant effect on the size and position of the peak which also made an impact on the pattern of the curve, signifying the formation of nanoparticles of various shapes and sizes. The nanoparticles showed enhanced antibacterial activity against selected bacterial strains which analyzed based on the zone of inhibition (ZOI) and minimal inhibitory concentration (MIC).Mohammed Nimeree MuntasirB.

The indicators are categorized in three different groups: prescribing indicators, patient care indicators and facility indicators. In this study, we aimed on the evaluation of prescribing indicators in four different public hospitals in Dhaka, Bangladesh. The hospitals are: Dhaka Medical College, Shaheed Suhrawardy Medical College, National Institute of Cancer Research & Hospital and National Institute of Diseases of the Chest and Hospital. We collected 50 prescriptions from each hospital and in total of 200 prescriptions were collected and assessed. After analysis we found that on average of 6.16 drugs are prescribed per encounter where the standard value is 1.6-1.8; about 51% prescription contained one or more antibiotic where the standard value is 20.0%-26.8%; about 46% encounters were with one or more injections even though the standard value is just 13.4%-24.1%; only 14.7% drugs were prescribed using generic names whereas the value should be 100% and lastly 41.3% drugs were prescribed from Essential Drug List but the standard is 100%. This study contains lists of different type of injections and antibiotic drugs prescribed to the individuals. From this study we can conclude that we are in need of strict scrutiny on the prescribing methods of our country, so that we can help in achieving the ideal environment for medical treatment.Md.
