So, being a conscientious member of society, we must go ahead to prevent these young minds from life-threatening addiction. In this paper, we approach a machinelearning-based way to forecast the risk of becoming addicted to drugs using machine-learning algorithms. First, we find some significant factors for addiction by talking to doctors, drug-addicted people, and read relevant articles and write-ups. Then we collect data from both addicted and nonaddicted people. After preprocessing the data set, we apply nine conspicuous machine learning algorithms, namely k-nearest neighbors, logistic regression, SVM, naïve bayes, classification, and regression trees, random forest, multilayer perception, adaptive boosting, and gradient boosting machine on our processed data set and measure the performances of each of these classifiers in terms of some prominent perform...

This research focuses on a domain-specific Chatbot that can be helpful for educational institutes. This Chatbot will be a virtual (representation) to the admission seekers. It will provide answers regarding the university, its departments, admission fees and other admission related FAQ. For the sake of the research, frequently asked questions of a university were collected and an unsupervised learning model along with natural language processing techniques was deployed to answer the questions of the admission candidates. Tokenization, stop words removal followed by vectorization were implemented for preprocessing the training data. User’s inputs were similarly processed and then tf-idf based cosine similarity applied to retrieve the best answer. Later, a user-centric evaluation metric was used to evaluate the model and as per the metric, our current model showed approximately 80% accuracy.

The MAC sublayer of IEEE 802.11 stands for WLAN (Wireless Local Area Network) is mainly includes two fundamental access methods. One is called DCF (Distributed Coordination Function), which uses Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) approach. Other is PCF (Point Coordination Function), which is based on polling to determine the station that can transmit next. This paper is mainly focuses on the delay measurement, throughput, and traffic load of the network and also the impact factor of the DCF and PCF method of accessing to analyze more performance of throughput and less delay.

With the introduction of the subject of Instructional Design, teaching is now looked upon as a stepped process through which students must be taken through. To this end many teaching models have been proposed and used by teachers all over the world. At the same time, it has been noticed that students who take “ownership” of their learning are most likely to become independent learners. Also, with the huge rise in demand for tertiary level education all over the world and more so in developing countries like Bangladesh developing successful models to manage the wave of new students has become even more important. In Bangladesh, the increased demand is coming from rural students who have had a limited access to proper primary and secondary education available in the rural areas of Bangladesh. This has added to the challenge of being able to deliver teaching that can turn around students who ha...

For the purpose of recognizing human activities, we selected three activities (running, walking, and steady state, e.g., sitting and lying). We used the Dynamic Time Warping (DTW) algorithm as a classifier to learn and detect activities. Due to its inherent nature, DTW can provide satisfactory accuracy even with very few training samples. Using smartphone’s gyroscope and accelerometer sensors, we recorded user data during various activities. To encounter personal traits, we made sure the users were of different age, height and gender. With the help of DTW as a real time classifier, we then identify the activities against matching templates. The obtained results showed sufficient accuracy, showing the effectiveness of the approach.

A couple of year ago since 2016 the online maintain vehicle has introduced by “Pathao” and “Ubar” both have car and motor cycle ride share. The main purpose of this paper is to focus the facilities of IT on transport basis of security, transparent cash-on-delivery, hassle-free communication, reduce waiting time for the passenger and the impact of IT on Bangladesh economy.
