Abstract

­

The software development in different fields leads to increase the requirements for effective, efficient and complicated software. Due to the huge amounts of software requirements, it is possible some errors to occur in the certain part of the programs and this means a real challenge for the software producer. The need for an effective test system is necessary for designing reliable programs and avoiding the errors that may appear during the software product. In this review, many techniques are discussed for the process of generating test cases which are a group of conditions that determine whether the designed programs are able to satisfy the user’s requirements or not. Fuzzy logic utilizes an operational profile in the process of allocating test case to improve the software quality, as well as the design of fault propagation path to predicts the software defects during the test operation, also the automatic generation for PLC test cases that produce a new track through the program code in order to minimize the test cases needed for large size program.

 Keywords: Software test, test case, program evaluation, reliable software system, test suite.

Abstract

­

The detection of the tumor region in medical images such as (MRI, CT, X-Ray) a boring and time-consuming task is by radiologists or experts. So, in this review the accuracy is needed for detection the tumor. The area of medical imaging is also reducing complexity and improving diagnostic precision with the growth of information technology. This review paper makes a comparison between the k-mean, and fuzzy c-mean algorithms to display the results and accuracy of them to detection the brain tumor. The execution of the k-mean algorithm is based on centroid, size, split process, threshold, epoch, characteristics, and number of iterations, while Fuzzy C-mean is executed on the basis of the fuzziness value and the termination condition in medical images. In comparing the efficiency parameters with the state-of-the-art processes, the experimental outcomes demonstrate the importance of medical images (MRI, CT and X-Ray) and the accuracy of each algorithm that have been discussed.

 Keywords: Brain Tumor, Medical Images, Pre-processing, Segmentation, Feature Extraction, K- means.

Abstract

­

Brain tumor is one of the commonest tumors. For the diagnosis of this disease, automated detection and classification are crucial. Magnetic resonance imaging (MRI) is a unique sort of imaging which is utilized for detecting these tumors and categorizing them as benign or malignant using special algorithms such as of K-Nearest Neighbors (K-NN) and Support Vector Machine (SVM). The classification of brain tumors through imaging can be divided into four phases: pre-processing, extraction, segmentation and classification. This paper reviews some recent studies that highlight the efficacy of K-NN and SVM accuracies in classifying brain MRI images as normal or abnormal, benign or malignant.

 Keywords: brain tumor, Magnetic resonance imaging (MRI), classification, SVM, K-NN.

Abstract

­

Internet use in the Kurdistan region of Iraq has grown dramatically and has become an essential element of our daily lives, with hundred ISPs on hand and constantly increasing number of users by using e-learning platforms. The need for feedback is deeply linked to student participation and peer evaluation. It is also an issue of evaluation quality; how many feedbacks is made available, how they are given to students, how they are accepted by students, and to how much they are integrated into future instruction and learning. In this paper, three instruments, documentation, interviews and questionnaires were carried out to collect the data. Documentation was used to know the experiences of the students during classroom teaching and learning. The data were collected from the system application on our website. The data were called documentation. A survey is conducted comparing the feedback received from students on e-learning courses at the Duhok Polytechnic University (DPU), with the results of analyzed 100 teachers’ e-learning courses in the Covid-19 period in 2020. Eighteen questions have been asked to 7709 students in 14 technical faculties (6 colleges and 8 institutes) at DPU. The students’ responses were classified to the questions related to teachers’ experiences on preparing courses, students’ interactions, using available e-learning tools and methods. A review has been made on (100) teachers’ courses in the Moodle platform as LMS (learning management systems) to reveal their course preparation, experiences on using available technologies. Our results showed 34.92% of participant students satisfied with e-learning, this means that 65.08% of students preferred face-to-face learning (in class), regarding the trustiness of feedback, reviewed courses and students’ responses which were significantly mismatched. This means that student feedback is not entirely reliable in the learning process.

 Keywords: E-learning, feedback, questionnaires, teacher experiences, survey.
