The combustion of these fuels has contributed to the worsening of climate change and global warming. Fossil fuels are not only detrimental to the environment, but they are also not sustainable. In the Philippines, the country is heavily dependent on fossil fuels, as 40% of its energy consumption comes from oil with the majority being diesel fuel. The country must find a solution to reduce its dependency on fossil fuels. An alternative solution are biofuels, because of its reduced carbon emissions compared to fossil fuels while acting as a substitute for fuel. Biofuels production in the Philippines has already been mandated by the Biofuels Act of 2006 resulting to a mandated utilization of biofuels. The recent typhoons parasite infestation in the country has led to the decreased production of biodiesel. Microalgae is then eyed as a potential feedstock for biodiesel production, because of its high oil yield per hectare and fast growth rate. An assessment of the production of algal biofuel is needed in determining the viability of algal biodiesel production in the Philippines. This study, therefore, proposes the use of the life cycle assessment (LCA) methodology as an assessment tool for the viability of the production of algal biofuel in the Philippines. This study focuses on the assessment of a cultivation system in the Philippine for biodiesel production. An Environmental Design of Industrial Products (EDIP) impact category is used for impact assessments. A previous study was already done in comparing the cultivation system with that of another algal cultivation system, however, there has not yet been a comparative study between the use of this cultivation system and with that of jatropha biodiesel production, one of the prospects for biodiesel production. Results show that the algal cultivation system has scored larger impacts due to its electricity consumptions. The fertilizer consumption of the algal cultivation system, however, shows promising results as it was able to achieve a lower impact score in certain categories.","PeriodicalId":284183,"journal":{"name":"2017 IEEE Canada International Humanitarian Technology Conference (IHTC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128666358","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}

For rescue teams to transmit and receive on-sight reports using live video and high quality images, the provisioning of seamless coverage with high data rates is inevitable. As cellular networks continue to evolve into more heterogeneous structures regarding the size of deployed cells, the implementation of traffic offloading strategies is essential to achieve high data rates and more power saving. In regard to network modeling, stochastic geometry has been considered in the literature as an efficient approach for modeling the locations of base stations (BSs). Moreover, stochastic geometry provides tractable mathematical expressions for key network parameters such as coverage probability and average data rate. In heterogeneous networks (HetNets), density and power of BSs in a given tier influence the volume of traffic offloaded to other tiers. However, these two parameters are generally constrained together in practical scenarios. In other words, given a BS density, the power per BS must be adjusted to satisfy the inter-tier traffic flow to maximized system throughput. Furthermore, in D2D networks the fraction of spectrum allocated to D2D links also affects the net achieved throughput. In this paper, we formulate the problem of jointly optimizing the power of small BSs (SBSs), SBS density, and the fraction of spectrum allocated for D2D communications in order to maximize system throughput for critical conditions such as rescue missions.","PeriodicalId":284183,"journal":{"name":"2017 IEEE Canada International Humanitarian Technology Conference (IHTC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130185134","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, the extra sensing requirement of CRN nodes results in high energy consumption. This lowers battery life, which is especially problematic in cognitive sensor networks. To counter this problem, in this paper, we propose a wireless energy harvesting (WEH) scheme to harvest RF energy from the ambience. We modify the popular energy efficient MAC protocol LEACH (Low Energy Adaptive Clustering Hierarchy) to incorporate energy harvesting. Our simulation results show RF energy harvesting is feasible only when the transmission power of the source is above 10 kW. This contrasts many papers that suggest to harvest energy from other low power wireless transmitters. Our work also shows that RF energy harvesting CRN can potentially benefit rural communities located within the high power radiation range.","PeriodicalId":284183,"journal":{"name":"2017 IEEE Canada International Humanitarian Technology Conference (IHTC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127136338","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}

In addition, there are studies to comprehend how brain reorganization occurs after the injury; to avoid the progression of the lesion and to recover lost functionalities. There have been assistive technologies and brain-computer interfaces (BCIs) developed to improve quality of life and allow more independence and mobility to people with SCI. Many countries of Latin America have limited information about the population with SCI, and due to the high economic and social impact of SCI, there is a huge need of investment in development of technologies for treatments, rehabilitation, low cost assistive devices and BCIs, that could be practical in clinics and accessible to the affected population and care-givers.","PeriodicalId":284183,"journal":{"name":"2017 IEEE Canada International Humanitarian Technology Conference (IHTC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129129155","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}

In particular, the research targets context-aware adaptation to usage requirements at the camp fragment level. Indeed, nowadays, cities are key resources to answer growing humanitarian needs in terms of sheltering and camps. These situations are increasing due to different factors related to the nature, climate change or human activities. Resilience is therefore essential at the levels of districts, cities and territories. A framework based on the parametric computational approach is developed for the design of refugee camp which consider the requirements needed and can allow the participation of refugees in the design process. The first application of this framework is applied in Luxembourg where the city is involved in the humanitarian crisis in Europe. The objective of this work is to help policy makers and humanitarians in the optimization of the spatial design of camps. The use of parametric modeling approach enables the optimization of space layout planning.","PeriodicalId":284183,"journal":{"name":"2017 IEEE Canada International Humanitarian Technology Conference (IHTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129991074","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 issues are headlines in the domain referred to as “humanitarian engineering”. Yet, despite the urgency, the majority of engineers do not spend their careers solving the problems where need is greatest. In what ways can young engineers be drawn towards working on the critical challenges being faced by so many people worldwide? By what means can a feeling of professional responsibility or duty be inculcated? How can the goals of humanitarian engineering be linked to young engineers' views of their own careers? This paper reviews one effort to address these questions by way of an online course linking questions of cultural dimensions, multicultural teams, and intercultural communication to humanitarian engineering, sustainable development goals (SDGs), and engineers' social responsibility. Pre- and post-assessments reveal several statistically significant trends that suggest the online course, entitled “Intercultural Engineering,” has some efficacy in shifting students' perspectives. As such, it appears to be a useful tool in supporting SDG 17, which seeks to revitalize global partnerships for sustainable development through shared values, visions, and goals.","PeriodicalId":284183,"journal":{"name":"2017 IEEE Canada International Humanitarian Technology Conference (IHTC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129529497","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}
