a comprehensive survey and analysis on access control schemes in cloud environment
Cybernetics and Information Technologies, 2016Co-Authors: P G Shynu, John K SinghAbstract:AbstractCloud computing has emerged as the most dominant computational paradigm in recent times. There are tremendous benefits for enterprises adopting cloud technologies. It provides resources and services on demand, pay-as-you go basis. This includes infrastructure, platform and software services. But there are still a number of security threats and challenges associated with utilizing cloud computing. A proper access control is the fundamental security Requirement in any cloud environment, to avoid unauthorized access to the cloud systems. As cloud computing supports multi-tenancy and has a various categories of users with different sets of security Requirements, traditional access control models and policies cannot be used. This paper discusses on various access control models used for cloud environment and presents a Detailed Requirement analysis for developing an access control, specifically for the cloud. A comprehensive study on various security problems associated with outsourced data on the cloud and their existing solutions are also described, with the future research directions.

Stack4Things: a sensing-and-actuation-as-a-service framework for IoT and cloud integration
Annales des Telecommunications Annals of Telecommunications, 2017Co-Authors: Francesco Longo, Dario Bruneo, Salvatore Distefano, Giovanni Merlino, Antonio PuliafitoAbstract:? 2016 Institut Mines-T?l?com and Springer-Verlag FranceWith the increasing adoption of embedded smart devices and their involvement in different application fields, complexity may quickly grow, thus making vertical ad hoc solutions ineffective. Recently, the Internet of Things (IoT) and Cloud integration seems to be one of the winning solutions in order to opportunely manage the proliferation of both data and devices. In this paper, following the idea to reuse as much tooling as possible, we propose, with regards to infrastructure management, to adopt a widely used and competitive framework for Infrastructure-as-a-Service such as OpenStack. Therefore, we describe approaches and architectures so far preliminary implemented for enabling Cloud-mediated interactions with droves of sensor- and actuator-hosting nodes by presenting Stack4Things, a framework for Sensing-and-Actuation-as-a-Service (SAaaS). In particular, starting from a Detailed Requirement analysis, in this work, we focus on the subsystems of Stack4Things devoted to resource control and management as well as on those related to the management and collection of sensing data. Several use cases are presented justifying how our proposed framework can be viewed as a concrete step toward the complete fulfillment of the SAaaS vision.

Activity-Fest: IEEE Website Requirements Specification Document
2018Co-Authors: Bakare MayoAbstract:Activity- Fest Is an application that will allow users to book a wide variety of fun leisure activities and events in their local area and in their country. The idea behind the concept of this project was chosen arose from an experienced that was encountered during work placements. After a long week of work undergrads found it challenging to find fun activities to do in the little free time they had. The traditional drinks and nights out were becoming a boring routine and repeated cycle. After research online was carried out for activities to do in Ireland, it was soon realized that there was not a real platform that specifies in satisfying this need for people in providing activities for people. This encouraged me to take on this project in creating a Detailed Requirement specification document which tackles a real life business need and also satisfies the business analysis project of my course that I am required to do. The project involves me gathering and documenting Requirements to be implemented for the activity fest activity provider app. Initially this involves outlining all the key stakeholders involved in the application. Once the stakeholders are identified, a variety of elicitation techniques will be used in gathering Requirements effectively. The main techniques that will be used are brainstorming sessions, multiple interviews with 2-3 stakeholders. 2 prototypes, document analysis, Requirement workshop and a survey. This requires plenty of research behind each technique and research on how their used and when is best to use it. The stakeholders of the project will be identified in the initial planning of the project. Their importance to the project will be illustrated in a Detailed matrix. Following the identification of the proposed techniques, they will be carried out amongst the most relevant stakeholders participating in a series of elicitation session with the aim to generate Requirements from different viewpoints of each stakeholder. The Requirements will then be recorded, documented and analysed. After this process, they will be prioritized with different analysis tools which will help determine which of the key Requirements will be implemented in app. The results will be used to formulate a highly Detailed IEEE Requirement specification document. Within the document functional and non-functional Requirements are formed and documented in detail. The results will be used by a development team to construct the Activity-Fest Ap

design and implementation of a high power battery charger of a hydroelectric connected pv plant
Advanced Materials Research, 2013Co-Authors: Huan Wang, Wei FengAbstract:In remote areas, the scheme of networking grid complementarily by the large capacity ofPV plants and the hydropower units becomes an important choice. After analyzing the design of ahydroelectric-connected PV plants, this paper presents a Detailed Requirement of a large capacitybattery charger. The Buck circuit topology is adopted as the topology of the battery charger satisfyingthe demand the high charging efficiency and reliability and a 3 phase phase-shifted interleavingtopology is adopted to resolve the problem of high power application. Finally a double-loop controlstrategy was designed for implementing the batteries three-stage charging control and PV MPPTfunction. A 150kW battery charger is developed and used in PV plant of the Yushu, Qinghai province,China. The experimental data acquired form
