Implementation of Wi-Ap; An IEEE 802.11b/g Based Electrical Switch Module With Web Enabled Interface for Electrical Appliances Control

The aim of this research study is to design and implement a Wi-Fi-based control panel for remote control of lights and electrical appliances with a web functionality that allows for wide area control via the intranet or Internet. This eliminates the inconvenience of moving from one switch to another for analog operation of light fixtures and appliance in home, office and campus environment. The wireless technology we adopted is IEEE 802.11 (2008) b/g, also called Wi-Fi (Wireless Fidelity) which operates in free band and is easily accessible. Wi-Ap (Wi-Fi Automated Appliance) control system contains a web portal which allows for management and control purposes via the intranet or Internet. We built a standalone Wi-Ap console that allows the wireless switching on and off of any appliance(s) that is(are) ) plugged into it. The prototype we built was tested within the Electrical and Information Engineering department, Covenant University, Nigeria intranet and the test achieved our aim of remote appliances control from a web portal vial the intranet

A manifesto for Web Science

A clarion call for a new research agenda has been sounded, notably by Berners-Lee et al (2006a 2006b) and Hendler et al (2008) for a ‘science of decentralised information systems’ to ‘discover’ generative mechanisms, and synthesise knowledge and technology to push both forwards. Computer Science alone - focussing as it does on the engineering/technology of the web - could not deliver the ambitions of this new agenda. Equally, other disciplines implicated in Web Science might use the web to support their research, or be interested in virtual life, but they lacked a coherent or unifying mandate for engaging with the web. By calling for Web Science these pioneers opened up a new space. But this is uncharted terrain. As a technology the web is still new. While it has grown rapidly and unexpectedly we are only just beginning to think about the web as a phenomena to be studied. The proponents of Web Science had the vision to see that this new approach had to include disciplines beyond their own; it had to be greater than the sum of the parts of individual disciplines. This is a radical call to leave disciplinary silos and work collaboratively to produce something bigger and better. Moreover, it takes in the founding principles of the web and a desire for a web that is pro-human: this is a call for a science that is capable of insight and intervention to create a better world. Our paper aims to take up this challenge and suggests how we might map the Web Science terrain. We come at this from a slightly different direction to the web science pioneers and want to demonstrate how social science can, and indeed must, contribute to developing Web Science. This paper will explore the contribution of social theory and sociological concepts that shape how we engage with the web. We focus on four key aspects which seem to be central to this understanding. Firstly co-constitution, the fact that the web both shapes and is shaped by humans/society. Secondly the importance of heterogeneous networks of multiple and diverse actors (including technologies themselves) that make the web as we know it. Thirdly the significance of performativity, that the web is an unfolding, enacted practice, as people interact with http to build ‘the web’ moment by moment. Finally, drawing these ideas together we see the web we have now as an immutable mobile or temporarily stabilised network. We use these ideas to map what web science could be and to suggest how we might use sociology to understand the web. Our aim is to provoke and stimulate debate and to move beyond superficial popular psychology and sociology (which envisages engineering human behaviour) and to challenge some of the ways in which social science has engaged with technology and technical actors. To facilitate this, and taking our lead from Donna Harroway, the paper sets out a radical manifesto for web science

Developing BP-driven web application through the use of MDE techniques

Model driven engineering (MDE) is a suitable approach for performing the construction of software systems (in particular in the Web application domain). There are different types of Web applications depending on their purpose (i.e., document-centric, interactive, transactional, workflow/business process-based, collaborative, etc). This work focusses on business process-based Web applications in order to be able to understand business processes in a broad sense, from the lightweight business processes already addressed by existing proposals to long-running asynchronous processes. This work presents a MDE method for the construction of systems of this type. The method has been designed in two steps following the MDE principles. In the first step, the system is represented by means of models in a technology-independent manner. These models capture the different aspects of Web-based systems (these aspects refer to behaviour, structure, navigation, and presentation issues). In the second step, the model transformations (both model-to- model and model-to-text) are applied in order to obtain the final system in terms of a specific technology. In addition, a set ofEclipse-based tools has been developed to provide automation in the application of the proposed method in order to validate the proposal.Torres Bosch, MV.; Giner Blasco, P.; Pelechano Ferragud, V.

Case based polishing process planning with fuzzy set theory

It is difficult to make optimal process planning for polishing product because of the complex processes and the multi-criteria, attributes and vagueness of process parameters. To solve this problem, this paper combines the methodologies of Case Based Reasoning (CBR) and fuzzy Set Theory (FST) to support process planners in planning processes and making decisions effectively for polishing product. Moreover, various mathematical models are designed and integrated to the Web Based Portal System (WBPS) which supports the optimization computation of process parameter settings and case reasoning for polishing product. Finally, some cooker samples from the collaborating company have been collected to demonstrate the effectiveness of Case Based Process Planning (CBPP) model. © 2008 IEEE.published_or_final_versionThe IEEE International Conference on Industrial Engineering and Engineering Management (IEEM 2009), Singapore, 8-11 December 2008.

Quality of Web Mashups: A Systematic Mapping Study

The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-04244-2_8Web mashups are a new generation of applications based on the composition of ready-to-use, heterogeneous components. They are gaining momentum thanks to their lightweight composition approach, which represents a new opportunity for companies to leverage on past investments in SOA, Web services, and public APIs. Although several studies are emerging in order to address mashup development, no systematic mapping studies have been reported on how quality issues are being addressed. This paper reports a systematic mapping study on which and how the quality of Web mashups has been addressed and how the product quality-aware approaches have been defined and validated. The aim of this study is to provide a background in which to appropriately develop future research activities. A total of 38 research papers have been included from an initial set of 187 papers. Our results provided some findings regarding how the most relevant product quality characteristics have been addressed in different artifacts and stages of the development process. They have also been useful to detect some research gaps, such as the need of more controlled experiments and more quality-aware mashup development proposals for other characteristics which being important for the Web domain have been neglected such as Usability and ReliabilityThis work is funded by the MULTIPLE project (TIN2009-13838), the Senescyt program (scholarships 2011), and the Erasmus Mundus Programme of the European Commission under the Transatlantic Partnership for Excellence in Engineering - TEE Project.Cedillo Orellana, IP.; Fernández Martínez, A.; Insfrán Pelozo, CE.; Abrahao Gonzales, SM.

Usability Inspection in Model-Driven Web Development: Empirical Validation in WebML

There is a lack of empirically validated usability evaluation methods that can be applied to models in model-driven Web development. Evaluation of these models allows an early detection of usability problems perceived by the end-user. This motivated us to propose WUEP, a usability inspection method which can be integrated into different model-driven Web development processes. We previously demonstrated how WUEP can effectively be used when following the Object-Oriented Hypermedia method. In order to provide evidences about WUEP’s generalizability, this paper presents the operationalization and empirical validation of WUEP into another well-known method: WebML. The effectiveness, efficiency, perceived ease of use, and satisfaction of WUEP were evaluated in comparison to Heuristic Evaluation (HE) from the viewpoint of novice inspectors. The results show that WUEP was more effective and efficient than HE when detecting usability problems on models. Also, inspectors were satisfied when applying WUEP, and found it easier to use than HE.Fernández Martínez, A.; Abrahao Gonzales, SM.; Insfrán Pelozo, CE.; Matera, M. (2013).

Lessons taught and learned from the operation of the solar energy e-learning laboratory

The solar energy e learning laboratory (solar e-lab) in Cyprus is a good example of a web-based, remote engineering laboratory. It comprises a pilot solar energy conversion plant which is equipped with all necessary instrumentation, data acquisition, and communication devices needed for remote access, control, data collection and processing. The impact that the solar e-lab had during its nearly 5 years of operation is indeed high. Throughout this period, the solar e-lab has been accessed by users from over 500 locations from 79 countries spread all over the world. In the period of November 2004 to October 2008, more than a million visits were recorded, out of which 25000 have registered on the site and surfed through studying the supplied material. Around 1000 hits concerned registered users that passed the pre-lab test and performed the experimentation part. The four years of operation of the solar e-lab demonstrated how the Internet can be used as a tool to make the laboratory facilities accessible to engineering students and technicians located outside the laboratory, including overseas. In this way, the solar energy e-learning lab, its equipment and experimental facilities were made available and shared by a number of interested people, thus widening educational experiences. Judging from the online evaluation reports that were received from the solar e-lab users during the last 2 years of operation, it can be concluded that there is nearly excellent satisfaction by the users

The Montegancedo Astronomical Observatory. The first freee remote observatory for learning astronomy

This paper describes the first open robotic observatory available to the public on the Internet (http://om.fi.upm.es), interactive and completely free access through a Web 2.0 application, which lets users manage professional astronomical devices and collaborate with other amateur users through a web browser. Its main goal is to open the astronomy to the society and that people learn informally about the cosmos by means of experimenting with real remote devices. Its architecture is made up by common collaborative Web 2.0 tools (such picture gallery, wiki, forum, chat, voting and discussing systems, etc.) and services and policies to offer meritocratically the observatory and its observing time. The paper presents an innovative approach which proposes a reputation system for sharing an online resource to encourage high-quality contributions, and the initial outcomes obtained since the observatory started in December 2008. This paper also describes the first experience using the observatory for carrying out online practical assignments in an Educational Innovation Project within the Technical University of Madrid during academic year 2008-2009 and using it for three subjects of these different degrees: Computer Science, Industrial Engineering, and Topography
