Smart Indoor Home Surveillance Monitoring System Using Raspberry Pi

Internet of Things (IoTs) are internet computing devices which are connected to everyday objects that can receive and transmit data intelligently. IoTs allow human to interact and control everyday objects wirelessly to provide more convenience in their lifestyle. The Raspberry Pi is a small, lightweight and cheap single board computer that can fit on human’s palm. Security plays a big role in a home. People concern about security by preventing any intruders to enter their home. This is to prevent loss of privacy and assets. The closed-circuit television (CCTV) is one of the device used to monitor the secured area for any intruders. The use of traditional CCTV to monitor the secured area have three limitations, which are requiring a huge volume of storage to store all the videos regardless there are intruders or not, does not notify the users immediately when there are motions detected, and users must always check the CCTV recorded videos regularly to identity any intruders. Therefore, a smart surveillance monitoring system is proposed to solve this problem by detecting intruders and capturing image of the intruder. Notifications will also be sent to the user immediately when motions are detected. This smart surveillance monitoring system only store the images of the intruders that triggered the motion sensor, making this system uses significantly less storage space. The proposed Raspberry Pi is connected with a passive infrared (PIR) motion sensor, a webcam and internet connection, the whole device can be configured to carry out the surveillance tasks. The objectives of this project are to design, implement and test the surveillance system using the Raspberry Pi. This proposed surveillance system provides the user with live stream of video feed for the user. Whenever a motion is detected by the PIR motion sensor, the web camera may capture an image of the intruder and alert the users (owners) through Short Message Service (SMS) and email notifications. The methodology used to develop this system is by using the object-oriented analysis and design (OOAD) model.

Exploring OOAD Concepts Through Course Projects

This paper presents the innovative approach carried out in conducting Object Oriented Analysis and Design (OOAD) lab course for post graduate students. OOAD lab course is designed in such a way that the students will be able to analyze, design and implement the real time problems. The lab course structure involves mainly two parts; in the first part selecting problem, analyzing the requirements and designing the chosen problem. The second part focuses on implementation of the design, completed in previous phase.We discuss the methods of OOAD and applied them for implementing the real world applications. Students have implemented the projects in this lab course through which they have explored the OOAD concepts. Problem selection choice is given to the students. In the first part students have done the design of the chosen problem using OOAD and UML concepts individually. This design is done through Rational ROSE tool. In second part, group of 2 or 3 students have implemented the application using JAVA and My SQL programming language.The outcome of this course, 15 projects like hospital, restaurant, vehicle booking, inventory, hostel and placement management system, etc. have developed by the students. Thus the activity of project development has improved the design, implementation and presentation skills of students. The performances of the students are measured in Continuous Internal Evolution (CIE) and Semester End Exam(SEE).

Evaluation of Model Driven Architecture-Based Instruction for Understanding Phase Transitions in Object-Oriented Analysis and Design

Object-Oriented Analysis and Design (OOAD) courses enable students to establish a requirements model of an application, successively transform those requirements into logical design models, and then transform the logical models into physical design models. However, students attending OOAD courses typically encounter difficulties in the transition. Model-Driven Architecture (MDA) provides a model transformation framework for transitioning between OOAD phases. Considering the advantages of MDA in phase transitions, this study proposes that integrating conventional OOAD instruction with the MDA framework and describing transition relations in diagrammatic representations might improve students’ understanding of the transitions. This study used an empirical design that involved using two treatments (MDA-based and conventional instruction) to examine the relevance of MDA-based instruction in the effective understanding of the transitions on the basis of cognitive load theory, the split-attention principle, and theories of representation format. The results indicate that, compared with conventional instruction, MDA-based instruction is more efficient because it improves mental efficiency by reducing extraneous cognitive load. This study can assist educators in understanding the difficulties in learning phase transitions and motivate researchers to develop more effective learning instructions for transitioning between OOAD phases.

Reusing business components and objects for modeling business systems: The influence of decomposition characteristics and analyst experience

Abstract Component-based development (CBD) relies on the use of pre-fabricated business components to develop new application systems, rather than developing them from scratch. It provides an attractive alternative to more established development methods such as object-oriented analysis and design (OOAD). Given the growing demands for using agile methods for software development, we examine if systems analysts are more effective at modeling business systems by reusing business components than by reusing objects. We also examine whether the influence of component or object reuse on modeling performance is moderated by prior experience in systems analysis and design. We evaluate the representational constructs of the two based on a set of decomposition characteristics, and postulate hypotheses comparing the two based on theories in cognitive psychology and human factors. We find that models generated by reusing business components are of higher accuracy than those developed by reusing objects. An interesting finding of our study is that IT professionals who are less experienced in systems analysis and design perform on par with experienced professionals, when modeling business systems by reusing components. We argue that the decomposition characteristics of components—with respect to granularity, quality, and focus—enable less experienced analysts to perform on par with more experienced analysts.

Concept Maps as Instructional Tools for Improving Learning of Phase Transitions in Object-Oriented Analysis and Design

Students attending object-oriented analysis and design (OOAD) courses typically encounter difficulties transitioning from requirements analysis to logical design and then to physical design. Concept maps have been widely used in studies of user learning. The study reported here, based on the relationship of concept maps to learning theory and semantic memory, suggests that integrating OOAD instruction with concept maps might help learners understand these transitions more clearly. An empirical experiment, involving two treatments based on concept maps and conventional instruction, was conducted to examine the relevance of concept map-based instruction for an effective understanding of phase transitions. The results indicate that compared with conventional instruction, concept map-based instruction is more efficient in improving learner understanding because of greater learner engagement and because of concept maps' properties when they are used as an information medium. This study can aid instructors in realizing the difficulties in learning phase transitions and motivate researchers to develop more effective learning instructions.

A Work System Front End for Object-Oriented Analysis and Design

This paper proposes that basic ideas from the work system theory (WST) and the work system method (WSM) might serve as a front end to object-oriented analysis and design (OOAD), thereby providing a path from business-oriented descriptions to formal, technical specifications. After describing the background motivation and summarizing work system concepts, the paper uses a hiring system example to show how two tools from WSM can be used as a front end for OOAD, in effect, a step before creating use case diagrams and other types of Unified Modeling Language (UML) artifacts. Potential benefits of this approach stem from a business-oriented question, “how can we improve this work system's performance,” rather than an IT-oriented question, “how can we create a technical artifact that will be used?”

A Study on the Difficulties of Learning Phase Transition in Object-Oriented Analysis and Design From the Viewpoint of Semantic Distance

Students in object-oriented analysis and design (OOAD) courses typically encounter difficulties transitioning from object-oriented analysis (OOA) to logical design (OOLD). This study conducted an empirical experiment to examine these learning difficulties by evaluating differences between OOA-to-OOLD and OOLD-to-object-oriented-physical-design (OOPD) transitions from the perspective of semantic distance in the context of semantic network theory. The experimental results indicated that two factors inhibit the learning of OOA-to-OOLD transition: the semantic distance between phases and the precise degree of transition relations. The OOA-to-OOLD transition exhibits a greater semantic distance than the OOLD-to-OOPD transition, which causes difficulty in retrieving and understanding the semantics of OOA-to-OOLD transition relations. OOA-to-OOLD transition relations are less precise, which causes learners to have difficulty in developing efficient schema acquisition and automation when learning OOA-to-OOLD transition. These results provide further insight into the cognitive processes of learners who are learning phase transition. This may guide educators to develop an effective learning instruction method for phase transition and motivate researchers to remedy the inherent deficiency of phase transition in OOAD by considering the cognitive processes of developers.
