A STUDY OF AN ECO-FRIENDLY STREET LIGHTING SYSTEM FOR A SUSTAINABLE FUTURE
(researchgate.net, 2022-08) Neelawathura, R. W; Siriwardena, S. D; Sinnathamby, R. A; Ruwandika, S
The fundamental goal of this research is to create something that is long-lasting, environmentally friendly, and energyefficient for everyday consumers. As a result, the concept of an automatic green street lighting system was proposed, addressing the issue of needless road illumination and, in particular without energy wastage. Street lighting when it is not required is a waste of resources and electrical energy in general. Modern civilization has adopted the philosophy of "Going Green," which is emphasized at all times, particularly in the engineering field. Engineers come up with novel ways to save energy while improving the efficiency of their goods. One of these methods is to use a smart system, which has applications in numerous areas of society, such as at home, at work, and so on. Our main goal is to reduce energy while maintaining user-friendliness. Smart systems, created years ago, are still the foundation and are used to this day, improving as time goes on and striving for even greater development.

RIA-Bus: A conceptual technique to facilitate the AJAX-based rich Internet application development
(Uva Wellassa University of Sri Lanka, 2015-01-29) Dissanayake, N. R; Dias, G. K. A
Rich Internet Applications (RIAs) have become quite popular in this era of Web2 (Lawton, 2008). Compared to the traditional Web Applications, RIAs are faster, responsive and they have rich Graphical User Interfaces (GUIs) (Paulson, 2005). Among plugin-based approach and script-based approach, Asynchronous Javascript And Xml (AJAX) – which is a script-based technique to develop RIAs – grabbed the demand of the engineers due to many good features of AJAX. AJAX uses stable languages HTML, CSS, JavaScript; it is free; and do not need third party plugins (Farrell & Nezlek, 2007). However the complexity of the AJAX based RIAs are considered high due to various reasons (Li & Peng, 2012) (Mesbah & Deursen, 2007). Hence, the application of Rapid Application Development (RAD) practices are not supported adequate in AJAX based RIAs engineering (Dissanayake & Dias, The Significance of Importance of an Architectural Pattern for AJAX Based Rich Internet Applications, 2014). To maintain the sustainability of both the developed RIA and the engineering project – not only in the initial development life cycle, but also in post deployment stages – it is important to identify the main cause of these complexities and address it. Methodology We conducted a literature survey to gain the background knowledge of the RIAs, AJAX, RAD, architectural patterns and the relationship between these areas. The main intention was to identify and understand the complexities and difficulties of enabling RAD in AJAX based RIA engineering. As we gain the knowledge and identify some facts related to the complexities in AJAX based RIA engineering, we conducted a cross-sectional survey to verify the facts identified in literature survey. Also understanding of the up to date nature of the AJAX based RIA development was gained by analyzing the data gathered in the cross-sectional survey. The targeted crowed was the individuals engaged in AJAX based RIA engineering; specifically in the design and development phases. Data were gathered using a structured questionnaire with closed end questions and analyzed using statistical methods. Parallel to the surveys, a series of experiments were conducted to understand and get the experience of AJAX based RIA designing and development techniques, tools, and complexities. This series of experiments was conducted as a prototype based incremental development. In each and every incremental complexities were identified, and some techniques to address the identified complexities were tested. The knowledge gained in the early iterations was applied to the later iterations. We used HTML5 and CSS3 for GUI development, JavaScript for client-side development along with jQuery library, and PHP as the server-side development language. Apache server was used to host the web application and for databases MySQL serer was used. Results and Discussion The key finding of the literature survey is, that the main reason for the complexities engaged in AJAX based RIAs engineering is, the lack of availability of architectural formalism for AJAX based RIAs engineering (Dissanayake, Dias, & Jayawardena, 2013). In the analysis of the cross-sectional survey, we derived and highlighted the following results. The understanding of the general AJAX architecture is not difficult, and there is a good usage of Computer Aided Software Engineering (CASE) tools in AJAX RIA development. However, the difficulty level of implementing AJAX features in the same page increases, with the number of AJAX features in the page (Dissanayake & Dias, 2014). One of the complexities we noted throughout the series of experiments is that the difficulties engaged in the file management of the project. Referring to the AJAX general architecture, standard practice when implementing an AJAX feature is, pointing the AJAX request to a dedicated PHP script file in the server. This dedicated script file contains the code for the logic, to provide the complete respond for the particular request. Usually these script files contain few lines of codes, needed to handle the single request. When the number of AJAX requests increases, the number of the script files also increase parallel. To provide more rich features in the application, the need for more AJAX features grows, and as more AJAX features implemented, probably the AJAX request handling script files will be piled up in the server. As the number of script files increases, the logic could be scattered and it may create a complex environment, where the management of the server-side implementation is difficult. This setting will lower the realization of the architectural structure of the system too. Furthermore – due to the aforementioned facts – in the needs of modifications of the RIA, the effort needed will be higher, and this environment may affect the sustainability of the project too. To control this situation we propose a conceptual technique, we name it as the RIA-Bus (Dissanayake & Dias, 2014). Instead of maintaining numerous small script files in the server to handle the AJAX requests, we advise to keep a single script file – what we call the RIA-Bus – which contains the code to receive all the AJAX requests; direct the processing of the request to the necessary scripts or functions; and respond back the client, with the results returned from the functions in the other script files. Figure 01 illustrates the architectural structure of the RIA-Bus. A parameter will be sent to the RIA-Bus along with the request by the AJAX engine, to indicate the type of the AJAX feature, which requests the service. Based on the type of the feature, the RIA-Bus can decide, to where the processing should be passed. RIA-Bus is responsible for reading all the data sent by the AJAX engine – using either GET or POST method – and pass the data to the function dedicated for processing the data. Figure 02 shows a sample PHP code of a RIA-Bus. The script files may contain code for all the logic of the application and organized in a way easy to manage. For an example all the user related functions may be written in one file and products related function may be written in another file. These files can be included into the RIA-Bus as needed and the functions in them can be called according to the type of the feature of the AJAX request.

Technology in retail marketing and the way forward with Gamification: An exploratory study
(SLIIT Business School, 2019-12-10) Alles, T.; Jayasooriya, S.
The retail landscape is evolving rapidly as firms embrace innovative technologies in an attempt to stay ahead of the aggressive competition prevalent within the industry. The focus of this paper deems to be to explore technologies used by retail firms in the execution of their marketing efforts as well as the drivers and challenges in adopting Gamification for such efforts. A qualitative inductive research approach was taken whereby critical analysis of literature was followed through with in-depth interviews with marketing professionals in the moderntrade retail industry. The interviewees were selected through judgmental purposive sampling technique and the thematic analysis was conducted in generating insights. Findings show that the retail firms currently employ several technologies in line with those discussed in existing literature such as loyalty card systems, digital signage, VR technologies, online Gamification amidst others in carrying out their marketing efforts. Mobile Instant Messaging & Autonomous shopping carts are to be employed in the near future while firms are receptive to experiment on Hologram technologies and In-store Gamification. Furthermore, key drivers that propel firms to implement novel technology like Gamification are; to generate customer insights, enhance customer experience and achieve marketing related KPI targets. Conversely, inadequate technology infrastructure, justifying focus on a niche crowd of tech-oriented customers and slow ROI pose as challenges in the process of Gamification adoption. The study offers theoretical contribution to the knowledge gap in this domain especially in the Sri Lankan context and while it is limited to modern-trade retailers future research can be extended to other formats of retail.
