(Daffodil International University, 2020-07-12) Rahman, Saidur
At present social context of Bangladesh, it is most important part to ensure proper protection of our assets. The security guard plays an important role in protecting the assets of the people from the evildoer. Now a days Lots of Security Guards agencies are providing professional protection for our assets. But most of the agencies are not well managed there service system for security guards. So, I want to build a mobile application that have the solution of this problem. Development of Android Application “Smart Guard” is an Android application where I figure out quite a good solution of managing and Collaborating for individual guard’s safety problem. When I research about my project then I can not found any security guard related mobile applications for our country. Very few of applications are developed by other countries and they didn’t developed urgent needed part of Security Guard sector. Some of security guard related android applications are: “Guardso Security Guard System, Security Guard App, Guard Patrolling System”. Even they cannot give a popper solution for managing and individual guard’s safety problem. So that, i wants to develop an Android Application “Smart Guard”. Here I try to provide a proper solution of Security Guard related problem. In this application a security guard can use an emergency button to seek help from other on duty guards. When a guard press the emergency button, an automatic emergency notification will be generate with the name of the guard and a help massage to all other on duty guard’s phone. If other on duty guards tap on the notification, they can see the exact geo location of the guard in danger. By using this mobile application a guard can easily give his attendance. Security Guards can easily see there on duty and off duty colleague’s profile. Guards can call their colleagues from this application and also see their current duty location on map. Guards can see duty post in category (Normal,Urgent,Regular) which was given by the admin. Guards can be used lots of interesting services like see their duty shift, pre generatev ©Daffodil International University meals reminder, Torch light tools, setting duty shift, changing language, received notification with vibration/music
Distributed Cooperative Space Time Trellis Code
(East West University, 9/25/2014) Rahman, Saidur; Ansary, Sabbir
The wireless communications industry has been undergoing tremendous changes in the last few years. There has been a spectacular growth in the internet and mobile communication services in the last decade. Wireless Internet and multimedia services are introduced in the 3G mobile phones, require much higher data rates than those available with current radio technology. Video telephony and picture messaging introduced by 3G phones generate huge up link traffic. Given a limited Spectrum the only way to support high data rates is to develop new spectrally efficient radio communication techniques. It was shown recently that multiple input multiple output (MIMO) system have a potential to significantly increase spectral efficiency in the wireless communications. Space Time codes are practical techniques used to approach the theoretical MIMO spectral efficiencies Unfortunately uplink transmit diversity is not directly applicable to the cellular due to the small size of the mobile station and electromagnetic interaction of antenna elements on the small platform. Furthermore the channels corresponding to different antennas are correlated because of the miniature size of the mobile phone. So, there is a need for such ideas to be extended to the macroscopic arena, where space-time coding is performed over transmit antennas that are not necessarily co-located. Mobile antennas are omni directional. Signals transmitted towards the destination can be "overheard" at the other MTs(partner). Partners (Adjacent MTs). process this overheard information and re-transmit towards the destination. These Partnering mobiles form a Virtual Antenna Array. This approach successfully gives solution to the problem of just one receiving antenna in a handset. In our proposed scheme space-time trellis coding is performed over transmit antennas that are not necessarily co-located. The Idea is called Distributed Space Time Trellis Coding. Cooperative Distributed Space Time Trellis Coding have also been analyzed to increase the performance of Distributed Space Time Code.
EFFECTS OF SUPPLEMENTING LEMON JUICE AND MOLASSES ON PRODUCTIVE PERFORMANCE, CARCASS CHARACTERISTICS AND HEMATOBIOCHEMICAL PARAMETERS OF COMMERCIAL BROILER
(A thesis submitted in partial of the requirements for the fulfillment of the degree of Master of Science in Animal and Poultry Nutrition Department of Animal Science and Nutrition Faculty of Veterinary Medicine Chittagong Veterinary and Animal Sciences University Khulshi, Chittagong-4225, Bangladesh, 2018-06) Rahman, Saidur
Two hundred forty Cobb 500™ unsexed broiler chicks were used in a 28-day trial in a poultry farm at Guimara, Khagrachari Hill district to study the effects of supplementing lemon juice and molasses on productive performance, carcass characteristics and hemato-biochemical parameters of commercial broiler. Lemon juice and molasses were added with drinking water and fed in addition to regular pellet diet. The experiment was carried out in a 2×4 factorial arrangement with 2 levels of lemon juice (0 and 1 ml/L of drinking water) and 4 levels of molasses (0, 0.5, 1 and 1.5% of drinking water from 1-2 wks and 0, 2.0, 2.5 and 3.0% of drinking water from 3-4 wks). Birds were randomly distributed into 24 floor pens where 10 birds were allocated per pen. All birds had free access to ad-libitum feeds and water. Results indicated that, live weight significantly (p<0.01) increased in 3rd and 4th weeks, weight gain increased (p<0.01) in 1st and 3rd weeks, feed intake improved (p<0.001) in 1st and 3rd weeks and FCR improved (p<0.05) only in the 1st week as the main effects of supplementing lemon juice in the drinking water of the commercial broiler birds. On average, during 0-3 weeks, lemon juice exerted positive effects (p<0.01) on feed intake and weight gain. However, only feed intake improved (p<0.01) during 0-4 weeks. Similar to lemon juice, molasses improved (p<0.01) live weight in 2nd, 3rd and 4th weeks, weight gain increased (p<0.001) in 1st and 3rd weeks and feed intake improved (p<0.05) in 1st, 2nd and 3rd weeks and FCR improved (p<0.05) in 2nd, 3rd and 4th weeks as the main effect. Overall, feed intake (p<0.001), weight gain (p<0.001) and FCR (p<0.05) were improved during 0-3 weeks and only feed intake improved (p<0.001) during 0-4 weeks. Unlike main effects, combined effects of lemon juice and molasses were significant only for weight gain in 3rd week (p<0.05) and FCR in 1st and 4th weeks (p<0.01). Main effect of supplementing lemon juice was positive for wing (p<0.05), drumstick (p<0.001), neck (p<0.001), skin (p<0.05), intestine (p<0.001), breast muscle (p<0.001), liver (p<0.05), head (p<0.001), abdominal fat (p<0.001) and feather weight (p<0.001). Similarly, main effect of supplementing molasses was positive for drumstick (p<0.001), neck (p<0.001), intestine (p<0.05), breast muscle (p<0.001), shank (p<0.05), liver (p<0.05), head (p<0.05) and abdominal fat weight (p<0.01). Combined effects were positive for dressing percent (p<0.05), wing weight (p<0.05), drumstick weight (p<0.05), breast muscle weight (p<0.001), thigh muscle weight (p<0.05), gizzard weight (p<0.05) and abdominal fat weight (p<0.05). Main effect of supplementing both lemon juice and molasses were significant (p<0.01) for glucose, albumin, total protein, LDL, HDL and cholesterol. However, combined effects were significant (p<0.01) only for glucose, albumin, LDL and HDL. There was a positive relationship between cholesterol and glucose (r=0.70; p<0.01) and a negative relationship between total protein and glucose (r=-0.80; p<0.001). Inclusion of 1 ml/litre lemon juice and 3% molasses in drinking water in addition to regular pellet diet is recommended for better growth, optimum FCR and desirable carcass characteristics in commercial broiler.

Stock market, a very unpredictable sector of nance, involves a large number of investors,buyers and sellers. Stock market prediction is the act of attempting to see the long run price of an organization stock or di erent money instrument listed on a monetary exchange. People invest in stock market supported some prediction. For predicting, the stock exchange prices people search such ways and tools which can increase their pro ts, whereas minimize their risks. Prediction plays a awfully necessary role available market business that is sophisticated and di cult method. A part of our thesis will be directed at assembling the required tools to aggregate nancial data from various sources. Here, we proposed a model by applying machinelearning to technical analysis. Technical analysis reviews the past direction of prices using stock charts to anticipate the probable future direction of that security's price. In alternative words, technical analysis uses open, close, high and low prices, still as its volume information to construct stock chart to work out that direction the protection ought to take, supported its past information. An arti cial trader can use the ensuing forecasting models to trade on any given stock market. The performance of the research is assessed using Dhaka Stock Exchange data.

Pharmaceutical supplies their product throughout rural Bangladesh. However collecting orders for product is very difficult, as the infrastructure does not allow easy communication. If order information or information regarding consumption of Pharmaceutical product was available, it would make order and delivery management system easier. To have an Improved Order Management and Delivery of Medicines of Pharmaceuticals We need an effective data collection from all parts of Bangladesh. The recent growth of mobile phones and infrastructure allows us to use this technology not only as data collection devise but also as a limited output device. This thesis explores how text messaging can solve the problems of data collection and dissemination throughout rural Bangladesh. Using this system product manufacture and distribution can be made more effective and less costly in terms of expired medicine, extra production run and distribution cost.
Sentiment Polarity Detection on Bengali Book Reviews By Word2vec and Hybrid Machine Algorithm
(DAFFODIL INTERNATIONAL UNIVERSITY, 2024-09-29) Rahman, Saidur
Despite sentiment analysis's significance in gauge public opinion, current methods frequently fail to account for Bangla and other languages sufficiently. Specifically, this work develops a Sentiment Polarity Detection on Bengali Book Reviews By Word2vec and Hybrid Machine Algorithm. A total of 2012 reviews, including both good and unfavorable assessments, were compiled from various sources. The study assesses several ML models, including Word2Vec, for feature extraction, RF, SVM, and a hybrid of the two. With superior recall, accuracy, and precision, the best model was the one that combined RF with SVM. Results showed that the most effective RF and SVM hybrid models scored 0.92%. On top of that, they took first place in the categorization report with an exceptional accuracy rate of 0.93%. These outcomes prove that it can easily handle complex Bangla text. Improved processing of the Bangla natural language is the goal of the suggested effort. It paves the way for more advancements, such as creating an AI-driven mobile app that can analyze sentiment in real time and make it more accessible than a web app
Situation of women with phycical disabilities: A study in Satkhira district
(University of Dhaka, 2014-04-24) Rahman, Saidur
The study was conducted among the women with physical disabilities based on broad objective of exploring the present situation of women with physical disabilities at Satkhira district in Bangladesh. For attaining the broad objective the study focuses some of important objectives (a) to gather information about the present situation of women with physical disabilities; (b) to identify the causes of disability, attitude of others towards them; and (c) to know some recommendations to overcome this problem. The study was conducted among the women with physical disabilities at satkhira district. The study has been employed qualitative research method and selected 08 women with physical disabilities through using purposive sampling method for the study. Findings of the study shows that of total population, 10% have a disability, more than half of whom are women, women with physical disabilities are more vulnerable. Prejudices, maltreatment, and poverty are the main responsible disability. It also reveals that disability makes them negligence among people, family, society, community, and relatives do not behave properly. It also shown that women with physical disabilities are very week than nondisabled person, at the time of moving they feel nervous and security less, valueless at work place and don’t get any kind of facilities. Sometimes they want to commit suicide. The promising findings of the study show that women with physical disabilities are the slower than in rehabilitation activities, the rehabilitation activities of government organization and NGOs are not well. But some initiatives have been taken for the betterment of disabilities like special education programs, in every district there have separate school for them, where they can take free education, they are getting different types of facilities from GOs and NGOs. It can be said that if Government and NGOs continue their train towards them one day they will be self-sufficient and contribute to our society like nondisabled person. Despite of hope it is observed that they are not aware about their rights related policy and provision but to improve their situation and for the betterment of their life, we have to reshuffle the laws and formulate new policies and laws.
Web Design and Development Submitted
(Daffodil International University, 23-01-29) Rahman, Saidur
Creating a website was the main objective of this internship. To construct web-based software or apps, various programming languages are employed. While some of them are only used to create the UI and front end of the software, others are also used to develop the back end. HTML3, HTML4, HTML5, CSS, and the Bootstrap Framework are some examples of programming languages used to create the front end of an application .The back end uses languages like PHP, Java, etc. Additionally, certain frameworks are widely used nowadays. By utilizing Model, View, and Controller, frameworks are essentially organized programming. It also goes by the name MVC .Because we can access a webbased application from anywhere in the globe, doing so is really helpful for us. In our daily lives, it is quite useful. Thus, "WEBSITE DESIGN AND DEVELOPMENT" is the topic I have chosen for my report. I gained a lot of valuable knowledge from working at Bluebird Interactive for my future profession. Another crucial challenge was finding solutions to real-world issues. This report covers all of the specifics of the WEBSITE DESIGN AND DEVELOPMENT education and training acquired over the internship.
