    This paper tackles a highly relevant issue, namely the relationship between climate justice and democracy. The driving motivation of the paper is to ask what principles of climate justice demand from democracies. The paper explores intrinsic and instrumental arguments and develops a sufficiency account: citizens are entitled to the emissions necessary not only to realize their basic needs but to participate as equals in political decision making

    Social networking sites like Facebook are not just an element of passing time but a platform for learning as well. The goal of this paper is to show the effectiveness of a Facebook application named 201C;Wishdom201D; to teach English language based on cloud platform. This application tries to introduce English language in an authentic and communicative manner to the students, where they have to assume different roles (i.e. avatar) to achieve a particular goal. For that purpose they communicate with the other avatar and participate in several quizzes. This study shows the performance of a group of students who played 201C;Wishdom201D; game and take a quiz as a part of their assessment. Their performance has been presented to show their success rate in learning English. The performance of the application is also measured based on Facebook Graph API. In addition, platform as a service (PaaS) of cloud computing from Heroku has been integrated to host the application and its compatibility is checked in this study

    Get PDF
    Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Information Systems and Technologies ManagementIn this recent time, the importance of cybersecurity and cyber defense is sky-high. Everyone uses different devices, IT infrastructures, and applications for various purposes at school, office, home, hospitals everywhere. With the enlightenment of technology, the nature of cyber-attack has been changed dramatically, and that is why the number of cyber-attacks have been increased. Enterprises face billions of Euros loss from such incidents; even the data loss and operational hazard may have a devastating impact not only on the service, security, privacy, brand image but also upon overall business. A constrictive and realistic CSCD (cyber security and cyber defense) strategy along with the proper implementation of it, can safeguard the enterprises and strongly from cyber attacks. In this paper, we prepare an improved CSCD control framework based on several hundreds of scientific papers and frameworks. Moreover, we identify different aspects and strategic elements by holistic CSCD control risk assessment and data analysis for preparing CSCD strategy and planning of different levels of organizations to maintain effective CSCD governance and cyber resilience

    Mathematical Modelling And Life-Cycle Energy And Financial Analysis Of Solar Kilns For Wood Drying

    There is a general challenge to improve the designs of solar dryers for the direct drying of various materials through the uses of robust models in conjunction with methods incorporating an appropriately defined set of performance parameters for evaluating the performance of solar kilns. However, the use of prevailing methods is unlikely to provide a sustainable means of comparison between various solar-kiln designs, unless a whole life-cycle perspective is taken into consideration. In order to address this key issue, a novel methodology for life-cycle performance evaluation of solar dryers has been developed in this thesis. To examine the capability and usefulness of the solar kiln model and its simulation procedure for predicting the drying behaviors for different solar kiln designs, the model was numerically solved for two typical greenhouse-type wood-drying solar kilns (Oxford and Boral). The assessment of life cycle embodied energy and embodied carbon values for the construction and maintenance of the two solar kilns (Oxford and Boral) by developing a life cycle assessment (LCA) model in “SimaPro 7.1.8 version”. To analyse the total life-cycle energy use in solar kilns, an innovative performance evaluation methodology, which considers the total life-cycle (LC) energy effectiveness in present-value terms, together with a defined set of present value performance indicators (PVPIs), has been proposed here. In the last stage of the thesis, a life-cycle cash flow (LCCF) analysis has also been carried out to compare how closely the life-cycle net energy (LCNE) and the LCCF approaches are aligned for the present case and how they can lead to significantly different recommendations for some other scenarios. In summary, the LCNE approach, together with the defined PVPIs, has been suggested to be considered as a robust and reliable method for life-cycle performance evaluation of solar kilns

    Feasibility Analysis of Embedding Optical Fiber Sensor Into Additively Manufactured Part

    Get PDF
    The research tried to examine the viability of the embedment of optical fiber sensors in Additively built components, packaging the sensors within the components, and characterizing the sensors for sensing a specified measurement. Optical fiber sensors are popular due to their small size, resilience against electromagnetic radiation, and reliability in potentially dangerous conditions. Embedding fibers inside a product allows for the monitoring of critical areas, allowing for preemptive action in the case of a breakdown. Coupons of Inconel 718 were made using laser powder-bed fusion (LPBF), with the fabrication settings tuned to determine whether such a development was possible. After the FBG sensors were inserted in the channel, thermal epoxy was injected to seal the package. After the sample specimen was created, they were put through some tests like fatigue and thermal tests to determine their properties. This was done so that designers in the future would have a road map to follow when creating such a component, and so that we could learn whether the design was viable in general

    Estimation of RFID Tag Population Size by Gaussian Estimator

    Radio Frequency IDenti cation (RFID) systems are prevalent in all sorts of daily life endeavors. In this thesis we propose a new method to estimate RFID tag population size. We have named our algorithm Gaussian Estimation of RFID Tags, namely, GERT. We present GERT under both {0,1} and {0,1,e} channel models, and in both cases the estimator we use is a well justi ed Gaussian random variable for large enough frame size based on Central Limit Theorem for triangular arrays. The most prominent feature of GERT is the quality with which it estimates a tag population size. We support all the required approximations with detailed analytical work and account for all the approximation errors when we consider the overall quality of the estimation. Our simulation results agree well with analytical ones. GERT, based on standardized frame slotted Aloha protocol, can estimate any tag population size with desired level of accuracy using fewer number of frame slots than previously proposed algorithms

    Do Muslims have equal right to free speech?

    Get PDF
    The right to free speech is perhaps a suspect virtue. In other words, writers and commentators may have the right to say what they want and artists, to express what they think or feel curious about. But they are morally obligated to maintain some degree of checks and self-censorship, and consider the socio-religious values and conventional morality that people cherish in a given cultural setting. A book or an artistic piece that insults people’s long-held views, beliefs, convictions and cultural practices and thus can potentially incite violent street demonstrations and can cause death/s is perhaps better not to be produced at all. Perhaps, the debate, whether or not freedom of expression is absolute, may remain a contentious issue for a long time. However, it is almost certain now that Muslims are currently the primary victims of a conceivable hypocrisy in the free speech discourse. While Muslim societies are maligned for a perceived lack of freedom of expression, Muslims do not have equal right to freedom of expression

    Literary tourism: exploring Charles Dickens’ Rochester

    Get PDF
    Among all the places that inspired Dickens’ work, Rochester High Street is perhaps the most remarkable for the intensity of its association with the novelist. Fortunately, modernisation has not been able to encroach upon High Street to eliminate the pristine nature of Dickensian memorabilia, as buildings in the area largely remain as they were during Dickens’ time. Walking on High Street gives the look and feel of Dickens’ world

    An Islamic reading of Thomas Gray’s “Elegy Written in a Country Churchyard”

    Get PDF
    Perhaps, the earliest literary scholar to significantly discuss the issue of looking at English literature from an Islamic perspective is Syed Ali Ashraf (1925 – 1998). His “Islamic Principles and Methods in the Teaching of Literature” (1978) is a foundational work that discusses the place of literature in a total Islamic worldview. He talks about the fundamental moral responsibility of man on earth and looks at literature from that perspective. He argues that, being human production, literature as a whole cannot be completely good and completely bad, stating: “No human activity is entirely good or entirely bad because only God is absolutely good and Satan is absolutely bad” (1978: 52). Therefore, when approaching a text, practitioners of literary studies should bear in mind that some ideas it transmits can be acceptable in Islam, while some others cannot. Given this conceptual premise, this study will look at Thomas Gray’s “Elegy Written in a Country Churchyard” (1751) from Islamic perspectives and will seek to identify common grounds and differentiations between Islamic teachings and Gray’s ideas as expressed in the poem

    Barriers and success factors for implementation and adoption of healthcare information systems in developing countries:a systematic literature review

    Get PDF
    Abstract. Developing countries often struggle to implement sustainable healthcare information systems (HIS) due to poor government policy and technological legacy. Bangladesh is a prime example where a large number of patients are deprived of proper healthcare simply because their data is fragmented and not digitally recorded. Several researchers have shown how standard healthcare systems in hospitals can reduce the complexity of patient management, thus creating room for serving more patients at the same time. Such standard systems can dramatically improve the scenario for developing countries. This thesis gives an overview of key barriers that is hindering developing countries to implement such HIS. It also accumulates the success factors to overcome the issues. This thesis used a systematic literature review (SLR) to analyze the relevant literature in the field of information systems. A review protocol was developed to conduct the SLR. Relevant studies were collected from three databases, IEEE Xplore, Ebsco Databases, ScienceDirect. The initial search resulted in 4014 studies. The search was further refined and through a process of selection using inclusion and exclusion criteria, 19 relevant primary studies were reviewed to answer the research questions. This study identified 24 barriers which have been grouped into six categories, and 19 success factors, grouped into four categories. The results show that HIS implementation in developing countries is hindered due to the lack of infrastructure, lack of education and awareness, lack of financial supports, cultural and political issues, resistance and support unwillingness, and lack of system quality. The findings also brought success factors as suggestions for successful implementation of sustainable HIS. The study found that utilization of resources to be most significant success factor which influences the successful HIS implementation
