An intelligent energy management system for educational buildings

There is a wide variation in the energy consumption between different educational institutions due to the adoption of different management strategies and different levels of occupants’ environmental understanding. The presence of large amounts of information and communication technology (ICT) equipment and heating, ventilation, and air conditioning (HVAC) system causes a major consumption of energy in higher education institution (HEI) buildings. The main objective of this research is to investigate the use of ICT to optimize the energy consumption in HEI buildings and reduce carbon dioxide (CO 2 ) emission. The first phase of the system has been implemented at King Saud University to measure energy consumption through sensors that read energy consumption of electrical appliances and devices every 10 seconds. The analysis of collected data allows us to develop and employ energy saving strategies that lead to a reduction in total energy consumption. Our preliminary results show that up to 17% of energy consumption can be reduced by simply dealing with standby energy loss of labs’ computers. The novelty of this research comes from the use of a functional database approach to deal with high volume of data and query performance and the incorporation of a timetabling system in energy management system

Frequency analysis of river water quality using integrated urban wastewater models

Copyright © IWA Publishing 2012.The definitive peer-reviewed and edited version of this article is published in Water Science and Technology Volume 65 Issue 12, pp. 2112–2117 (2012), DOI: 10.2166/wst.2012.127 and is available at www.iwapublishing.com.In recent years integrated models have been developed to simulate the entire urban wastewater system, including urban drainage systems, wastewater treatment plants, and receiving waterbodies. This paper uses such an integrated urban wastewater model to analyze the frequency of receiving water quality in an urban wastewater system with the aim of assessing the overall system performance during rainfall events. The receiving water quality is represented by two indicators: event mean dissolved oxygen (DO) concentration and event mean ammonium concentration. The compliance probability of the water quality indicators satisfying a specific threshold is used to represent the system performance, and is derived using the rainfall events from a series of 10 years' rainfall data. A strong correlation between the depth of each rainfall event and the associated volume of combined sewer overflow (CSO) discharges is revealed for the case study catchment, while there is a low correlation between the intensity/duration of the rainfall event and the volume of the CSO discharges. The frequency analysis results obtained suggest that the event mean DO and ammonium concentrations have very different characteristics in terms of compliance probabilities at two discharging points for CSO and wastewater treatment plant effluent, respectively. In general, the simulation results provide an understanding of the performance of the integrated urban wastewater system and can provide useful information to support water quality management

Future Military Spacecraft Power Systems

During the past several years, a number of military space mission studies have concluded with interesting new information on the future needs and directions of military spacecraft power systems. In all cases, the trend to higher power level, for continuous as well as pulsed requirements, is clear. Although precise dates are impossible to define at this time, military spacecraft of the next twenty years will require steady state electrical power in the range of 10 to 100 kilowatts with pulsing capabilities in the megawatt region. As such, the major thrust of the DOD space power technology program focuses on the development of military power systems which will extend capabilities to the upper end of these ranges while maintaining technology applicability to the current lower level power requirements. Because of assumed delivery and orbital transfer limitations, the weight and volume of these high power systems must be kept as low as possible without sacrificing the reliability and lifetime of the power systems. These constraints necessitate the early application of very advanced solar/array battery systems and possibly nuclear reactor power supplies. As usual, the survivability of the power systems to natural and imposed radiation environments remains a concern for military systems. In addition to the above, the need for spacecraft system autonomy is being emphasized and programs to enhance the fault-tolerance and energy management of future military power systems are being initiated

Ranking irrigation schemes based on principle component analysis in the arid regions of Turkey

ArticleWater is a scarce resource and thus irrigation schemes in arid regions have become more important. The irrigation sector which uses most of the water resources has to cope with global warming, disasters and water scarcity around the world, particularly in the Mediterranean countries, including Turkey. Irrigation schemes, which were built by DSI (State Hydraulic Works) and whose operation and maintenance management was transferred to water user associations, play a crucial role in irrigated agriculture in Turkey. In order to improve the performance, weakness and strengths of irrigation schemes are determined by performance indicators (system operation, financial and production efficiency) which show the overall information about them. In the present study, seven irrigation schemes located in an arid region of central Anatolia were chosen to assess the irrigation performance using principal component, correlation and cluster analysis while quality index showed the rank of the irrigation schemes. We found that the average total annual volume of irrigation supply was 7648.58 m3 ha−1 and the average relative water supply was 1.91 during the 11 years between 2006 and 2016. In this region, higher inverse correlations were due to using surface irrigation methods (51.3%). As of 2017, the irrigation schemes have weak water distribution systems, on an average, consisting of 55.5% open canals, 22.5% canalette and only 10% pipes. According to the quality index, financial and system operation indicators are more effective than that of production efficiency indicators. In conclusion, average irrigation ratio (55.68%) can be increased by improving the water distribution system, and the technology used on both management and farm levels
