Analytical Study on the Use of Bloom's Taxonomy for the Assessment of Exam Questions in the Perspective of Computer Science
(Daffodil International University, 2018-12) Tusher, Raja Tariqul Hasan
Bloom’s taxonomy has been exploited in numerous fields of studies. It is a classification of learning objectives within education that educators set for students. The cognitive domain within this taxonomy is designed to verify a student's cognitive level during a written examination. Educators may sometimes face the challenge in analyzing whether their examination questions comply within the requirements of the Bloom’s taxonomy at different cognitive levels as it is difficult to apply consistently to assessment tasks in introductory programming courses. This research paper shows the Bloom’s classification categories along with keywords and question verbs those are commonly used in the exam questions in computer science and provides a consistent interpretation of some baffling keywords with concrete exemplars that will allow computer science educators to utilize Bloom’s Taxonomy for programming assessment. Using Bloom’s Taxonomy to help design examinations could greatly improve the quality of assessment in introductory programming courses. The main goal of this paper is to give hands on computer science and engineering teaching and learning and perk up the excellence of computer science and engineering education. In the future, this research can be further extended to automate the assessment of exam questions according to the Bloom’s taxonomy of the cognitive domain.

(IEEE, 2023-03-21) Eshan, Sumit Hassan; Hasan, Raja Rashidul; Sarker, Abdullah Al Mamun; Zabin, Sadia; Tusher, Raja Tariqul Hasan; Rahman, Md. Abdur
This paper is all about to design an antenna for brain tumor detection using a novel material Kapton polyimide. A brain tumor, which has the potential to spread throughout the body and result in cancer, is one of the worst disorders. Using a novel material and observing variation in the S1,1 parameter to spot brain cancers is the main objective of this paper. An on-body microstrip patch antenna constructed in the K band and a three-size brain tumor in a brain phantom model were employed to identify the existence of brain tumor. This antenna can operate between 4 and 14 GHz. The resonance frequency of the proposed antenna was discovered to be 12.96 GHz in free space. A VSWR of 1.00 and −92.06 dB S1,1 was also measured in this area. S1,1 is −49.93 dB at 8.58 GHz in the Normal Brain and −40.51 dB at 11.87 GHz in the Tumor Affected Brain.

An E-shaped micro strip patch antenna is designed and analyzed in this paper which operates in MICS (402.0-406.0MHz) band. The Performance has been observed on a body of human phantom model as well as in free space with different conducting material for the designed antenna. The height of this antenna is taken 1.5mm from the ground plane. At resonance frequency of 405 MHz the S11 parameter is obtained in free space is -23.26dB for conducting material of aluminum and -17.96dB is measured on human phantom body at 405 MHz of resonance frequency. FR4 is used as substrate material. The Specific Absorption Rate (SAR) is found to be 0.3562 W/kg by placing the antanna on human phantom model. VSWR and directivity has been analyzed also.

(IEEE, 2018-01-15) Sultana, Sadia; Hasan, Raja Rashidul; Mondal, Tonmay Kumar; Tusher, Raja Tariqul Hasan; Zabin, Sadia
In this paper, A standardized and implantable planar inverted f antenna is accomplished with modified design, featuring balanced size miniaturization for wireless communications. This antenna has an intensified reliability and feasibility in turns for performing for biomedical application. The proposed antenna is represented For MICS BAND. MICS band contains 402 to 405 MHz resonant frequency. This band has been chosen because of its tractability towards higher bandwidth with the decreasing size of the antenna. 12.5 × 12.5mm2 miniature dimension is offered this antenna. The antenna is observed a better resonant performance at different substrate material. Four different types of substrate materials as Rogers RO3010, Rogers RT3210, Rogers RT6010 and Alumina were used in order to design the antenna to observe which one yields a better performance for the desired antenna. The purpose of using those comparisons is to find the lowest return loss and also get an acceptable efficiency which causes the higher gain in the desired. antenna. Return losses, Radiation Patterns, S-Parameters is observed and analyzed the antenna performances by using CST Microwave Studio.
Sentence Similarity Measurement for Bengali Abstractive Text Summarization
(10th International Conference on Computing, Communication and Networking Technologies, ICCCNT 2019, IEEE, 2019-12-30) Masum, Abu Kaisar Mohammad; Abujar, Sheikh; Tusher, Raja Tariqul Hasan; Faisal, Fahad; Hossain, Syed Akhter
Text summarization is a massive research area in natural language processing. It reduces the larger text and provided the prime meaning of a text document. Find the meaning of the larger text needed of a proper text analysis which gives a better text summarizer. Abstractive text summarizer gives a summary which can present or not present in the text document. The machine produces a text summary after learning from the human given summary. Sentence similarity is a way to judge a better text summarizer. It is exploring the similarity between sentences or words. This paper we discuss several methods of sentence similarity and proposed a method for identifying a better Bengali abstractive text summarizer. We used human given summary and machine response summary sentences for similarity measurement where both sentences contain a Bengali short text. There are several approaches to English sentences similarity measurement, and we applied some of the approaches for similarity measure for our Bengali text which give a satisfying result. For our given methods we collect data from online and social media and create a summary of those texts. After creating a summary pre-processing this text and generate a summary from our abstractive text summarization model. All summary sentence similarity measurement cases using the method provided an effective value and optimal result.
Spin Coated Multi-Walled Carbon Nanotube Patch Antenna for Breast Cancer Detection
(John Wiley and Sons, 2023-10-27) Hasan, Raja Rashidul; Jasmine, Jasika; Saleque, Ahmed Mortuza; Eshan, Sumit Hassan; Tusher, Raja Tariqul Hasan; Zabin, Sadia; Nowshin, Nadia; Rahman, Md. Abdur; Tsang, Yuen Hong
Early detection of breast cancer can be a life-saving measure for many patients. The inaccessibility of X-rays, magnetic resonance imaging (MRI), and other medical facilities in many resource-constrained areas hinders the early detection of breast cancer. In this paper, the use of a rectangular patch antenna for breast cancer detection is proposed by using multiwall carbon nanotubes (MWCNTs) as patch material. The proposed antenna is designed by CST software which is (30 × 40 × 1.66) mm in dimension. A breast model is designed including tumor and cancerous tumors by specific tissue properties for observing the antenna performance in different cases. In free space, the return loss of the designed antenna is observed at −33.414 dB. Moreover, the S11 is examined in a normal breast, a breast including a normal tumor, and a breast including a cancerous tumor is −32.641 dB, −34.94 dB, and −35.22 dB respectively. It can be utilized on a human body phantom model due to its adaptability and reduced radiation properties. The proposed antenna is miniature in size, cost-effective, easily portable, and eco-friendly. It can be used as a first screening tool for breast cancer patients, particularly in resource-constrained regions.
