A large proportion of today’s software development is unsuccessful. One reason for this is thought to be lack of attention to the user. Maintaining a user-centred focus during software production is regarded as a major problem. Introducing an HCI designer role into the software team (they usually function as external advisors) is thought to be a means of addressing this problem. Issues surrounding the introduction of an HCI designer role into software teams were explored by a qualitative investigation. Participant-observation studies were carried out on two year-long software projects, with the researcher performing the role of HCI designer within the software teams. Aspects of comprehension within the team were found to be fundamental to successful collaboration. Prototypes were found to be an effective means of facilitating team members' comprehension of HCI design intent, and of maintaining conceptual integrity. However, this use of prototypes was flawed because they introduced the potential for ambiguity and they were inaccessible. Focusing on the collaboration of the HCI designer and programmers, requirements for a prototype-centred explanation tool were specified to exploit the potential of prototyping to facilitate comprehension, by addressing the flaws discovered. Such a tool, called ‘ProtoTour’, was designed and implemented, based on the requirements specified. An experiment was conducted with 22 commercial programmers to ascertain whether a ProtoTour representation of an existing, commercially developed prototype, facilitated comprehension more effectively and was more accessible than a conventional prototype. Results of the experiment found that programmers using ProtoTour gained a significantly better understanding of HCI design intent, than programmers using a conventional prototype. Those using ProtoTour also asked the HCI designer significantly fewer questions about the HCI design intent. Results suggest that prototype-centred explanation tools have the potential to improve programmers’ comprehension of HCI design intent. Introducing an HCI designer into a software team was found to be an effective way of improving the user-centred focus of software during production. A prototype-centred explanation tool appears to have potential as a means of helping programmers comprehend HCI design intent.

This research paper explores the impact of COVID-19 and the shift to remote work on project management practices across multiple industries. Through interviews with project managers, the study finds that companies with pre-existing remote work policies were better equipped to handle the transition to remote work. In contrast, companies without pre-existing policies faced increased challenges in communication, team morale, and workload management. The study also highlights the struggle to maintain work-life balance, the importance of communication, and the need to address technical difficulties. Project managers emphasized the importance of accountability and maintaining productivity during remote work. Overall, the study finds a positive shift in the collective outlook on remote work, with employees expressing a strong preference to continue working remotely even after the pandemic. The study emphasizes the evolving role of project managers in adopting a holistic approach to resolving interpersonal and managerial issues within teams during remote work.

Цель диссертации – аналитически обеспечить разработку системы взаимопомощи и социализации для лиц с ограниченными возможностями здоровья на базе существующей версии локальной платежной системы. Актуальность обусловлена огромными масштабами сообщества инвалидов в России. Проблема инвалидности остается болезненной, как с точки зрения медицины, так и с социально-экономической стороны. В работе решаются задачи: анализ предметной области, изучение альтернативных расчетных средств, электронных платежных системы. Изучены результаты исследований прошлых лет, а также модели и методики разработки продукта. Проведена полная аналитика системы, посчитаны все затраты, подготовлен проект внедрения, а также создан прототип системы для проведения деловых игр. Объектом исследования являются методы и инструменты изучения рынка ИКТ и разработки инновационного продукта. Предмет – аналитическое обоснование вывода на рынок и разработки инновационного продукта для лиц с ОВЗ. Научная новизна заключается в том, что в работе с помощью современных моделей и методик обоснована необходимость создания системы взаимодействия инвалидов, которая объединяла бы в себе функции интернет-магазина и ведение балансов счетов участников. Система уникальна и не имеет конкурентов. Практическая значимость заключается в создании аналитической базы сообщества инвалидов России и подготовке материалов для введения ЛПС в жизнь сообществ. / The purpose of the dissertation is to analytically ensure the development of a system of mutual assistance and socialization for people with disabilities based on the existing version of the local payment system. The relevance is due to the huge scale of the disabled community in Russia. The problem of disability remains painful, both from the point of view of medicine and from the socio-economic side. The paper solves the following tasks: analysis of the subject area, study of alternative means of payment, electronic payment systems. The results of previous years' research, as well as models and methods of product development are studied. A complete analysis of the system was carried out, all costs were calculated, an implementation project was prepared, and a prototype of the system for conducting business games was created. The object of the research is methods and tools for studying the ICT market and developing an innovative product. The subject is an analytical justification for launching and developing an innovative product for people with disabilities. The scientific novelty lies in the fact that the work with the help of modern models and techniques justifies the need to create a system of interaction of disabled people, which would combine the functions of an online store and maintaining the balance of accounts of participants. The system is unique and has no competitors. The practical significance lies in the creation of an analytical base of the Russian disabled community and the preparation of materials for the introduction of LPS into the life of communities.

Bayou St. John, an urban water body extending south from Lake Pontchartrain, has two anthropogenic structures that regulate flow from the Lake . The City of New Orleans has plans to remove the inner control structure to improve water quality. Field and numerical methods used in this study show removing this structure increased water elevations throughout the Bayou but resulted in lower water elevation signal amplitudes that caused a lower tidal flow exchange from north to south. Bulk Richardson numbers showed mixing was inversely related to flow and the Bayou generally remains stratified. Resuspension of contaminated sediment could negatively impact the local ecology but predicted shear stress values did not reach a critical value (0.1 N/m2) for resuspension. Removal of the waterfall structure will benefit Bayou St. John by decreasing energy losses from the Lake, however a more pronounced tidal signal from Lake Pontchartrain is required to flush the Bayou.

This report is going to be focusing on the development of a promotion page and login system for the web production company Adoreyou. The promotion page and login will be parts of a new taxi application for iPhone that lets the customer book a taxi and drivers manage the requests from the customers. Taxi application’s that let customer’s book trips are nothing new but they are constantly being explored and developed. The most common practice is to let the customer fill in from what address he or she wants to be picked up and to where he or she wants to be taken. Then the price is set in the application depending on the distance and most likely other factors like weekday and time. Some of them do not have functionalities such as being able to choose which type of car you want to order or managing payments from the app itself. This taxi app will be developed to take it to the next level and utilize GPS to locate cars close to the customers. The promotion page will be constructed in HTML and CSS. The login system will be constructed in the PHP framework Codeigniter and connected to Parse.com through an API. The project has been using the so called waterfall model to develop the promotion page and the login system. The model has been used throughout the project and each stage was been checked with the project manager on Adoreyou before the next stage was initialized.
