Prioritization of Software Functional Requirements from Developers Perspective

Prioritizing software requirements is important and difficult task during requirements management phase of requirements engineering.To ensure timely delivery of project, software developers have to prioritize functional requirements.The importance of prioritization increases when size of requirements is big.Software for large enterprises like the Enterprise Resource Planning (ERP) systems are more likely to be developed by a team of software developers where large size requirements are distributed in parallel team members.However, requirements are dependent on each other, therefore development of pre-requisite requirements must be carefully timed and should be implemented first.Therefore, assigning importance and priority to some requirements over others is necessary so that requirements can be available on time to developers.This paper proposes a prioritization approach for functional requirements on the basis of their importance during implementation.The design of research method consists of Analytical Hierarchical Process (AHP) technique based on spanning trees.Through spanning trees, dependent requirements were linked in hierarchical structure and then AHP were applied.As a result of prioritization, requirements were distributed in such a way that dependency among requirements of developers were kept minimum as much as possible so that waiting time of requirements for their pre-requisite were reduced.With reduced effect of dependency in requirements of parallel developers, timely delivery of software projects can be assured.

Implementing Sentiment Analysis on Real-Time Twitter Data

This study has been undertaken to investigate the application of Sentiment Analysis on real time Twitter data collected through Twitter API. Sentiment analysis is a progressive field of natural language processing. It is a way to detect the attitude, state of mind, or emotions of the person towards a product, service, movie, etc. by analyzing the opinions and reviews shared on social media, blogs and so on. Various social media platforms such as Facebook, Twitter and so on allow people to share their views with other people. Twitter has become the most popular social media platform that allows users to share information by way of the short messages called tweets on a real-time basis. These tweets consist of user opinions towards a particular topic, trend, or issue. These Tweets are first extracted in real time through application programming interfaces (APIs) using hashtags and keywords, about political figures such as Donald Trump, Narendra Modi, etc. They are then categorized based on their subjectivity and polarity. Machine learning algorithms such as Naive Bayes and Random Forest Classifier are then used to accurately predict these Tweets as negative or non-negative (positive or neutral). This will give us an understanding on general public reception towards these figures. Our experimental results show that it is possible to process data in real-time, and obtain information continuously, albeit with varying classification accuracy due to real- time data collection
FUTURE PIANO PERFORMERS’ DEVELOPMENT OF THE CREATIVE POTENTIAL IN HIGHER EDUCATION PEDAGOGICAL INSTITUTIONS

training of musicians in pedagogical institutions of higher education has emerged, which is significantly different from the training of music teachers of a comprehensive school. This is due to the different goals and objectives assigned to the training of specialists in the creative professions, who are able to think outside the box and solve creative problems in the process of future practical activity. The development of creative potential of the musician is of a particular relevance in this context. Since the main purpose of his activity is the concert performance of musical works, and the most accurate disclosure of their artistic content to the audience.The purpose of the article is to discover the essence of the student-performers’ creative potential and to explore the professional personal qualities necessary for their development.To achieve the goal, a set of theoretical methods were used, including: analysis and systematization of scientific sources in order to identify the state of development of the problem under study; terminological analysis to determine the nature and content of key research definitions; analysis, generalization, systematization to determine the potential effectiveness of methodological approaches.The article deals with the essence and content of the concepts of “creativity”, and “creative potential”, and explains the structure of these concepts. On the basis of the analysis of modern scientific works, the problem of the development of future piano performers’ creative potential in pedagogical institutions of higher education is revealed. The professionally important personal qualities of the performing musician, which effectively influence his performing activity and provide creative activity in the process of development of the mentioned formation, are distinguished. The author explores the place of creative potential of future instrumental pianists in the process of developing their professional personal qualities. The necessity of the development of pianist-performers’ studied formation in the process of performing is argued. Thus, the development of the creative potential of instrumentalist pianists takes place in the course of vocational training in higher education pedagogical institutions. The conducted research made it possible to conclude that the instrumentalist pianist should possess such necessary personal qualities: willpower, motivation, interest, musical thinking, which promote creative activity and are aimed at realization of musical and creative abilities of a musician. The development of the specified qualities contributes to the effective process of preparation of the future performer and gives him the opportunity to achieve a high level of skill and to carry out successful instrumental and performing activity.

Ultrasound Images Registration Based on Optimal Feature Descriptor Using Speeded Up Robust Feature

Image registration plays a significant role in the medical image processing field. This paper proposes a development on the accuracy and performance of the Speeded-Up Robust Surf (SURF) algorithm to create Extended Field of View (EFoV) Ultrasound (US) images through applying different matching measures. These measures include Euclidean distance, cityblock distance, variation, and correlation in the matching stage that was built in the SURF algorithm. The US image registration (fusion) was implemented depending on the control points obtained from the used matching measures. The matched points with higher frequency algorithm were proposed in this work to perform and enhance the EFoV for the US images, since the maximum accurate matching points would have been selected. The resulted fused images of these applied methods were evaluated subjectively and objectively. The objective assessment was conducted by calculating the execution time, peak signal to noise ratio (PSNR), and signal to noise ratio (SNR) of the registered images and the reference image which was fused manually by a physician. The results showed that the cityblock distance has the best result since it has the highest PSNR and SNR in addition to the lowest execution time.

The structure and performance of these technologies were examined. Based on three devices, languages have been tested. Aspects such as RAM load, time between views, time to save data to the database and time to save data to file were tested as a part of the analysis. Two research hypotheses have been put forward: "Swift has a better performance than Objective-C" and "Swift has a simpler structure than Objective-C". The results obtained confirm that Swift is more efficient than Objective-C. Research into the structure of codes has proven that the newer language has a simpler structure than its predecessor.
Using Augmented Reality Application to Reduce Time Completion and Error Rate in PC Assembly

In the present context of globalization, the demand for assembly skill has increased and play an essential role in todayâ€™s industry. The traditional assembly instruction, face-to-face and manual instruction, may contain unimportant information that can result in misinterpretation, which in turn may increase the number of error and takes longer time to complete the task. A new technology (AR) claims to increase the efficiency of assembly task by directly visualizing computer generated 3D information in the real environment. Therefore, this study aims to determine the impact of AR on the time of task completion and the number of error made during the assembly task. The comparative user study was quantitative involving 18 users divided into either AR group or traditional group performing a pc assembly task. Statistical analysis revealed that the time of completion and error rate for two different group is statistically significant. The findings showed that the use of AR application has resulted in decreasing the number of error made and shorten the time to complete the task than the traditional instructional manual in assemble a pc. Considering these result, it can conclude that augmented reality application is an effective and beneficial tool to be applied in assembly and education.

MATHEMATICAL MODELING OF MAGNETOTELLURIC FIELD IN ONE-DIMENSIONAL PIECEWISE GRADIENT MEDIUM

The solution of forward problems of magnetotelluric sounding for a case of one-dimensional piecewise gradient environments is received. Two problems are considered: the problem of calculating the impedance on the Earth’s surface for a gradient model of the upper half-space (Earth's atmosphere) and the problem of determining the magnetotelluric impedance for layered, piecewise-gradient models of the geological medium, which allow mathematical modeling of the magnetotelluric response functions and study the interaction of electromagnetic field and gradient models of lithosphere media. Such models extend the possibilities of development of the theory and practice of magnetotelluric research, first of all, when solving inverse problems, which is associated with the advantage of analytical solutions over numerical solutions of inverse problems of geophysics in terms of sharp reduction of their dimensionality. The main focus of the work is on the study of geodynamic processes in passive electromagnetic monitoring, the foundations of which are laid in the article (Alexandrov, Rybin, Zabinyakova, 2018).
A GAN Based Multi-Contrast Modalities Medical Image Registration Approach

Most current multi modalities medical image registration approaches are concerned about registering one modality image to another. However, in the real world, medical image registration may be involved in multiple modes, not just two specific modalities. To this end, we propose a multi-contrast modalities medical image registration modal (Star-Reg net). It uses a single generator and discriminator for all contrasts of registrations amount several modalities. Furthermore, the proposed approach is trained in an unsupervised way, which alleviates the requirement of manual annotation data. The experiment on the IXI dataset demonstrates the Star-Reg net effectiveness in multi-contrast modalities medical image registration.
Accesible co-creation tools for people with intellectual disabilities: working for and with end-users

In a world defined by rapid change, the search for solutions to societal challenges has become more complex calling for new paradigms of innovation focused on collaborations with the community and users. Co-creation approaches in the design and production of a service or product can bring low-cost innovation and unique and personalized customer experiences leading to user acceptance of a product or service. Under a co-creation perspective, the participatory approach developed in the MINDInclusion project aims to improve the inclusion of people with intellectual disabilities into public places and society by using a co-created online tool based on people with disabilities’ personal experiences. Paying special attention to the Design thinking method, the main goal of this experience was to co-create cognitive accessible design tools that guide the collection of users and other stakeholders experiences in the process of defining problems and solutions. To this end, 14 researchers and educators worked defining together a set of guiding exercises and design thinking methods for the 4 co-design cycles. To add an interactive and playful approach two tools were created to gather information to recreate as a final output “personas scenarios”, an “empathy map” and expected “use scenarios” that will guide the development of the web-tool based on user-centred specifications. The results have shown two tools. The former was an adapted game board about public places based on the traditional monopoly game and the latter a diary with a set of activities that will facilitate the collection of contextual information. Previous experiences have shown that co-design process can promote greater social cohesion, acceptance and empowerment. However, working with people with intellectual disability presents several challenges since the co-creation process needs to be cognitive accessible. This experience resulted in the creation of two cognitive accessible tools that can be extrapolated to other contexts.
