An important input in the hydrologic system that we translate into a hydrologic model is precipitation. In the Philippines, its tropical location and orientation being subjected to the Southwest Monsoon winds make it abundant with rainfall. It is one of the countries in the world with the greatest recorded rainfalls. Nevertheless, during the dry season, the country experiences water scarcity, compromising water supply for various uses. In impoundments such as the Magat Dam, water allocation to different stakeholders - irrigation and hydropower - has to be optimized for fair water distribution. Much needed in decision-making is to have an accurate information of what is to be measured. Rainfall in a watershed is a distributed phenomenon, hence, rain gauges in a large catchment has to be in distributed in the area to be able to get a more correct representation of the rainfall distribution.

This paper discusses the measurement of river flow during typhoon events using available equipment such as propeller-type current meter and the pressure-type depth gauge used by Mapua FRAMER Project. Alternative improvised approach is also discussed. It highlights the difficulty and the hazard accompanied by the methods and hence, the need to utilize technologies available is recommended. For the case of tropical Philippines, these technologies should be weather-proof and reliable, aside from being affordable for deployment in remote places. Recording and automated devices are also necessary features particularly for remote hardly accessible areas.

In this paper, we describe the hybridization of Microsoft Azure and Ionic for the development of a platform to track air quality in the Azores Archipelago, Portugal. The Azores region has had a sharp increase in tourism, which has led to greater public investment in sustainable tourism practices. The platform under development will access data logs from a wireless network of thermoelectric sensors, and allow users to upload data from locations outside the wireless network. The uploads will be done using a cross-platform Ionic app that is in progressive development. The app will be easily customizable and scalable across all web browsers and platforms, including desktop and mobile. The data uploaded will be stored on Microsoft Azure's Cloud infrastructure and accessible via our application. This paper focuses on the experimental setup, the collection of data pertaining to air quality and the display of the data, based on a timeline that starts from the most recent data updates and continues into the past. Data from individual sensors can also be isolated for display based on the location of the sensors. This research has been undertaken by the University of Washington, Tacoma in collaboration with the University of the Azores and the Federal University of Paraíba, Brazil.

In this paper, a reinforcement learning method is used to tune a non-linear reactive control model parameters of a two-body point absorber Ocean Wave Energy Converter (OWEC). In particular, an Actor-Critic algorithm, as a model-free method is adopted for the maximization of the energy extraction, adaptive to the sea state. Different values of Power Take-Off (PTO) control parameters are applied to the system to observe reward and penalty of the taken action. Reward is determined by the average power over a specific time horizon lasting several wave periods. A two-body point absorber, simulated in WEC-Sim, is developed as the agent in order to validate the control strategy for different wave conditions. Results for the analyzed sea states verifies that the proposed non-linear control law learns the optimal PTO control parameters in specified sea states.

The reliable and resilient operation of the smart grid necessitates a clear understanding of the intra-and-inter dependencies of its power and communication systems. This understanding can only be achieved by accurately depicting the interactions between the different components of these two systems. This paper presents a model, called modified implicative interdependency model (MIIM), for capturing these interactions. Data obtained from a power utility in the U.S. Southwest is used to ensure the validity of the model. The performance of the model for a specific power system application namely, state estimation, is demonstrated using the IEEE 118-bus system. The results indicate that the proposed model is more accurate than its predecessor, the implicative interdependency model (IIM) [1], in predicting the system state in case of failures in the power and/or communication systems.
