Fossil fuels account for more than three-fourths of today's global energy consumption. 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...
On this paper, a study of state-of-art technologies and techniques for energy harvesting from piezoelectric materials with a focus in bulk power harvesting and production is performed. This study includes improvements in mechanical and electrical configurations to be considered in order to design and implement high-performance energy harvesting systems as well as primary performance and costs estimations...
Cities consume high energy per unit area as a result of rising concentration of population and therefore can play an increasingly crucial role in driving global sustainability. Though integrating energy efficiency and sustainability can prove challenging, the fusion of both objectives is a critical step towards a green future. This paper focuses on building and transportation sectors which have the...
As a part of an Early Warning System, it has been developed a receiver of warning message, which has mainly DTT ISDB-T, FM RDS and Sound power submodules. This receiver is able to process warming messages over DTT and radio FM, with the purpose of activating an electronic siren and alerting to a neighboring population. In this context, this paper proposes a management module based on SNMP for the...
Traditional means of communication rely on a centralized service provider, which may not be functional in the wake of a disaster. With a traditional cellular service provider, when somebody (Alice) wants to send a text message to someone else (Bob), the message is sent from Alice's phone to a cellular network and then finally to Bob. This process happens regardless if they are located on opposite...
The required broadband for school and school board depends on curriculum delivery, the administrative and operational needs of the school and many other factors. These represent very different usage patterns, but both require a high level of reliability and performance. Therefore, there are no standards define what is the suitable broadband for the school and school board. This article is the first...
This paper examines the limitations of conventional communication systems during disaster recovery and discusses alternative wireless solutions that can assist with post-disaster relief operations. Factors such as network infrastructure, deployment requirements, localization and tracking architecture, and autonomous control are considered. One of the biggest challenges is that conventional communications...
Automatic islanding and reconnection are commonly required at the point of common coupling between microgrids and macrogrids. Islanding systems open the point of common coupling during short circuits, open circuits, and dangerous backfeed conditions in the macrogrid. Automatic synchronizing systems provide reconnection by dispatching multiple distributed energy resources to reduce slip and voltage...
Technologies have advanced to serve humanity and food is one of the primary and basic need of human being. More than 80% of people in Bangladesh depend on agriculture, directly or indirectly. However, proper irrigation by water pump cannot be maintained due to frequent power outages, unavailability of grid lines in remote areas and scarcity/cost of fuel to run pumps. This paper shows the viability...
In September 2009, the IEEE Board of Directors approved the new IEEE tagline — Advancing Technology for Humanity — as recommended by the IEEE Public Visibility Committee. Aligned with the IEEE tagline, IEEE Standards Association takes the initiative to address ethics in engineering design under “Ethically Aligned Design: A Vision for Prioritizing Human Wellbeing with Artificial Intelligence and Autonomous...
The needs of vulnerable populations have been addressed, traditionally, by an ecosystem of private and public agencies that rely on donations (goods, money and services) which they re-distribute based on their perception of what is needed and where. This approach lacks a comprehensive understanding of the demand side as well as the ability to coordinate between various suppliers of goods and services,...
The paper addresses computational design as a key technological asset in the development of the post-disaster responses related to temporary housing. 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...
Visible light communication (VLC) system has been widely used in underground mines, to support communication-blind areas, due to its superior benefits compared to Wi-Fi. These benefits include low energy consumption, wide frequency spectrum (430–790) THZ, higher data rates and small-sized infrastructure. Moreover, radio waves have poor underground communication capabilities, due to irregular data...
Wireless sensor networks (WSNs), part of the fast emerging Internet of Things will be playing vital role in transforming our lives. Potentially huge number of these sensors will soon be deployed to perform simple to complex tasks such as automatically controlling heat and light in smart homes to guiding autonomous vehicles and missiles. A big challenge in WSN is providing energy. Battery management...
