This paper presents the investigation of the use of position-sensing diode (PSD) - a light source direction sensor - for designing a vision-based navigation system for a perching aircraft. Aircraft perching maneuvers mimic bird’s landing by climbing for touching down with low velocity or negligible impact. They are optimized to reduce their spatial requirements, like altitude gain or trajectory length...
Heating, Ventilating and Air-conditioning systems have a significant share in the energy consumed by buildings. Development of a highly accurate thermal model is the first step in designing an efficient air-conditioning system. In this regard, this paper proposes a semi-nonlinear thermal model — ordinary differential equation with parameters as nonlinear functions of ambient temperature and cooling...
This paper carries out load profiling of Singapore housing units and office buildings using bottom-up method for peak load reduction through optimization. Housing units in Singapore are classified according to the number of rooms, ranging from one to five. Average daily, monthly and yearly electrical usage of all these units is obtained. To explore the strategies for peak load reduction, a mathematical...
