Integrating building and urban semantics to empower smart water solutions
Current urban water research involves intelligent sensing, systems integration, proactive users and data-driven management through advanced analytics. The convergence of building information modeling with the smart water field provides an opportunity to transcend existing operational barriers. Such research would pave the way for demand-side management, active consumers, and demand-optimized networks, through interoperability and a system of systems approach. This paper presents a semantic knowledge management service and domain ontology which support a novel cloud-edge solution, by unifying domestic socio-technical water systems with clean and waste networks at an urban scale, to deliver value-added services for consumers and network operators. The web service integrates state of the art sensing, data analytics and middleware components. We propose an ontology for the domain which describes smart homes, smart metering, telemetry, and geographic information systems, alongside social concepts. This integrates previously isolated systems as well as supply and demand-side interventions, to improve system performance. A use case of demand-optimized management is introduced, and smart home application interoperability is demonstrated, before the performance of the semantic web service is presented and compared to alternatives. Our findings suggest that semantic web technologies and IoT can merge to bring together large data models with dynamic data streams, to support powerful applications in the operational phase of built environment systems

Design of a Remote Real-time Groundwater Level and Water Quality Monitoring System for the Philippine Groundwater Management Plan Project
Recent technological advances allow us to utilize remote monitoring systems or real-time access of data. While the use of remote monitoring systems is not new, there are still numerous applications that can be explored and improved on, one such is groundwater level and quality monitoring. In the Philippines, the extraction of groundwater for both domestic use and industrial use are manually monitored by the government’s concerned agency and is done at least once per year. With this current setup, the real and significant state of the groundwater is not reflected in a way that is most valuable to the government and to the community. This project aims to design and develop a remote real-time groundwater level and quality monitoring system. It is intended to provide quantitative data for policy makers in addressing recurrent water shortages in the Philippines. This paper discusses the designed system composed of three modules: power module, sensors and control, and data visualization. These three modules provide real-time data from far-flung locations while being energy-sustainable. Dry runs of the system in a controlled environment yielded excellent results — average data accuracy of 96.63% for all six (6) groundwater quantity and quality parameters namely: pH, temperature, electrical conductivity, total dissolved solids, salinity, and static water level (SWL), and 90.63% data transmission reliability. Initial deployment of the system on one of the groundwater monitoring well in Metro Manila, Philippines returned a 91.16% data transmission reliability. The system is currently installed in 20 groundwater monitoring sites all-over the Philippines and is scheduled for more installations

Open source SCADA systems for small renewable power generation
Low cost monitoring and control is essential for small renewable power systems. While
large renewable power systems can use existing commercial technology for monitoring and
control, that is not cost-effective for small renewable generation. Such small assets require
cost-effective, flexible, secure, and reliable real-time coordinated data monitoring and
control systems. Supervisory control and data acquisition (SCADA) is the perfect technology
for this task. The available commercial SCADA solutions are mostly pricey and
economically unjustifiable for smaller applications. They also pose interoperability issues
with the existing components which are often from multiple vendors. Therefore, an open
source SCADA system represents the most flexible and the most cost-effective SCADA solution.
This thesis has been done in two phases. The first phase demonstrates the design
and dynamic simulation of a small hybrid power system with a renewable power generation
system as a case study. In the second phase, after an extensive study of the proven
commercial SCADA solutions and some open source SCADA packages, three different secure,
reliable, low-cost open source SCADA options are developed using the most recent
SCADA architecture, the Internet of Things. The implemented prototypes of the three open
source SCADA systems were tested extensively with a small renewable power system (a
solar PV system). The results show that the developed open source SCADA systems perform
optimally and accurately, and could serve as viable options for smaller applications
such as renewable generation that cannot afford commercial SCADA solutions
Intelligent rainwater reuse system for irrigation
Os avanços tecnológicos na área da Internet das Coisas têm vindo a criar cada vez
mais soluções na área da agricultura. Estas soluções são bastante importantes para a
vida, uma vez que conduzem à poupança do recurso mais precioso, a água, sendo esta
necessidade de poupar água uma preocupação mundial.
A dissertação propõe a criação de um sistema Internet das Coisas, baseado numa
rede de sensores e actuadores interligados que monitorizam automaticamente a qualidade
da água da chuva que é armazenada dentro de um tanque, a fim de ser utilizada para
irrigação.
O principal objectivo é promover a sustentabilidade, reutilizando a água da chuva
para sistemas de irrigação, em vez da água que normalmente está disponível para outras
funções, tais como outras produções ou mesmo tarefas domésticas.
Foi desenvolvida uma aplicação móvel, para o Android, para que o utilizador possa
controlar e monitorizar o seu sistema, em tempo real. Na aplicação é possível visualizar os
dados que traduzem a qualidade da água inserida no tanque, bem como realizar algumas
acções sobre os actuadores implementados, tais como iniciar/parar o sistema de rega e
despejar a água em caso de má qualidade da água.
O sistema implementado traduz uma solução simples com um elevado nível de eficiência
e testes e resultados obtidos, dentro do ambiente possível.The technological advances in the area of Internet of Things have been creating more

as they lead to the saving of the most precious resource, water, being this need to save
water a concern worldwide.
The dissertation proposes the creation of an Internet of Things system, based on a
network of sensors and interconnected actuators that automatically monitors the quality
of the rainwater that is stored inside a tank, in order to be used for irrigation.
The main objective is to promote sustainability by reusing rainwater for irrigation
systems, instead of water that is usually available for other functions, such as other
productions or even domestic tasks.
A mobile application was developed, for Android, so that the user can control and
monitor his system, in real time. In the application it is possible to visualize the data
that translate the quality of the water inserted in the tank, as well as perform some
actions on the implemented actuators, such as start/stop the irrigation system and pour
the water in case of poor water quality.
The implemented system translates a simple solution with a high level of efficiency
and tests and results obtained, within the possible environmen
