Indeed, it threatens more than 1.5 million people worldwide and affects a quarter of the land in less than 100 countries, it spreads over half a billion hectares per year and reduces the surface water and groundwater. Thus, according to a report by the Food and Agriculture Organisation written in 1993, the direct and visible impacts of desertification are the damage on crops, on livestock, on the electricity productivity, etc. Indirect impacts are lack of food production, poverty, social upheaval, rural exodus to cities. In this paper, our work consists in modelling the degradation process of land whose advanced level leads to the desertification. The first step consists in assessing the degradation of land with the MEDALUS model developed by the MEDALUS project of the commission of the European Union. This model assesses desertification by its sensitivity index which is the geometric mean of four quality factor indexes of soil, vegetation, climate and management (land use). This assessment method uses the major part of the parameters influencing the land degradation process. The second step is to model the land degradation process using cellular automata (CA) approach. For that purpose, the study area will be divided into a regular grid of cells. Initially, each cell has a state (desertification sensitivity index) whose evolution at each discrete time step depends on the states of its neighbours through a built transition function. As a result, this study allows to introduce a dynamical process in MEDALUS model. Indeed, from an initial configuration of an area, the model can predict its evolution over time and space according to a continuous state transition function that extend the classical CA approach and fit to the MEDALUS model parameters.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121291919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the more common assessments in an engineering programme are group-based, design and build projects. These projects often require a disproportionate amount of time due to coordination between members and resources for acquiring materials. This study relates an attempt to reduce this burden by utilising a common project as an assessment point for two separate courses: Practical Prototyping Skills and Introduction to Energy Engineering. The challenges faced by instructors in creating a project that would adequately address their individual learning outcomes are presented, along with the students’ perspective on this approach. Student surveys indicated that there was a clear understanding of how the project related to both courses and that they had sufficient support for the project, while lecturers highlighted several positive outcomes such as more student emphasis on the project, a higher standard of project and collegial support in the design and administration of the project.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121724539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These temporary houses provide a space in which many persons can live. Although these spaces are meant to be temporary, in many cases due to the lack of financial wherewithal, these temporary houses serve as a medium to long-term housing for those who receive them. The topographical and geotechnical environment in which these houses are built not only vary across the Americas and the Caribbean but varies within a single country. This study analyses the current foundation designs used by Food for the Poor in the country of Jamaica, taking into consideration Jamaica’s unique hilly terrain and geotechnical environment. The study makes recommendations for the use of alternative foundation designs that are still economical for construction and are better when considering the life cycle cost of these structures. The use of bamboo as a reinforcement in concrete for the foundation design is also analysed and compared against the traditional reinforced concrete and mass concrete designs. The results demonstrate that when bamboo is used as a reinforcement with concrete it has an increased flexural strength, but still do not exceed the flexural strength of traditional reinforced concrete, that utilizes steel reinforcement.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130871063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Independent variables collected in linguistic form require intuition which can be potentially biased. A collection of qualitative research papers on bias in models was perused to identify the causes of bias. Decision-making in the manufacturing, finance, law, and management industries require solutions from a complex assortment of data. The popularity of combining decision-making with artificial intelligence (AI) for intelligent systems causes concern, as it can be a predisposition to a true solution. A true solution avoids impartiality and maintains repeated results from a natural phenomenon without favoritism or discrimination. This paper appraised the development of the decision-making environment to identify the path and effect of bias on the variables used in models. The literature reviewed was associated with the design of a decision-making criterion rationalizing the application of variables. The influences on variables were observed with respect to the available resources, environment, and people. This list was further extended to consider the constraints of the resource, customer, network, and regulation fed to the structure. The involvement of bias was founded because of the need for rational decision making, cognitive misperceptions, and psychological principles. The study of variables showed the opportunity for a conscious bias from unethical actions during the development of a decision-making environment. In principle, bias may be best reduced with continuous model monitoring and fair adjustments. Ignoring these implications increases the chance of a bias decision-making model. It also influences the decision result and may be avoided with an ethical and fair quality review. The paper increases the awareness of bias in decision-making and guides actors to the identification and avoidance/reduction of bias effects. This may be a guide for the reduction of the model error to achieve a true solution.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125510281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With increase in demand of lattice towers, a critical review on approach for analysis is highly essential to ensure reliable and safe structures. In this paper, a comparative study is taken up on methodologies followed in both national standards (India, America) for assessment of wind loads on bare tower, linear accessories, discrete accessories along with design resistance of members and connections for Two different configurations – Square angular tower, Triangular Hybrid Tower. From the detailed analysis, it is concluded that, American standard (ANSI/TIA-222H) is using Ultimate windspeed for calculation of wind loads based on risk category of structure along with strength reduction factors based on criticality of components compared to Indian Standards (IS 875(Part 3)-2015, IS 802) which resulted lesser wind load on structure i.e., 30% in Square Tower (Oblique wind direction) and 23% in Triangular Hybrid Tower using ANSI/TIA-222H. Also, no major difference observed for calculation of member capacity and connection. Therefore, it is concluded that Tower weights approximately reduces by 10-15% based on Tower configuration using ANSI/TIA-222H compared to Indian Standards","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"45 14","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114027815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, payment delays continue to plague the construction industry to date. Delay payments generally have an adverse effect on a company’s cash flow, leading to extensions on overdraft facilities, ultimately increasing their borrowing. Late payment of commercial debt adversely affects the liquidity of contracting companies sometimes leading to insolvency. This study examined the impact of the contractual payment period and payment process on the cash flow of contractors executing projects for the Special Purpose Company (SPC) E. The sample population chosen for this research consisted of 100 small and medium contractors within the SPC-E to illustrate the varying effects of the payment delays on the contractors mostly affected. A review of previously published literature along with a questionnaire survey distributed, determined the objectives of the paper. Statistical analysis using IBM SPSS software further analyzed the data collected using Cumulative Means, Relative Importance Index, Spearman’s Rank Correlation and Analysis of Variance (ANOVA) to test the hypothesis. The complicated bureaucratic payment process utilized by the SPC-E resulted in the cascading adverse effects on the contractor’s cash flow. The findings also indicated that there has been no significant improvement to the delayed payment issue over the past decade. The implementation of Prompt payment legislation or statutory adjudication is recommended to ensure the sustainability of small and medium contractors.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"84 Pt 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129007611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 210 specimens of the GSA blended SCHPCs comprising 105 cubes (100 x100 mm) and 105 cylinders (150x300 mm) were cured in water for 7,14,28 ,56, 92,120 and 180 days hydration periods and the compressive strength and Modulus of elasticity determined. The linear relationships were studied with regression analysis. The findings revealed that all the mixes met the Modulus of Elasticity values requirement of 18,000N/mm2 to 42,000N/mm2 and the compressive results show that three substitution levels of 0%, 10% and 20% attained the proposed design strength (40-130 Mpa) and also satisfied the requirement for self-consolidating and high strength concretes. In conclusion, 0%-20% GSA substitutions (SCHPCA0-SCHPCA20) indicated a strong linear relationship with regressions values obtained varies between 0.842 and 0.954 for the two variables. Addition of GSA as SCM has improved the mechanical properties of SCHPC and creates a strong relationship between the compressive strength and Modulus of Elasticity.","PeriodicalId":206492,"journal":{"name":"Proceedings of the International Conference on Emerging Trends in Engineering & Technology (IConETech-2020)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115187322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
