Anti-drift in electronic nose via dimensionality reduction: a discriminative subspace projection approach [PDF]
, 2018 Sensor drift is a well-known issue in the field of sensors and measurement and has plagued the sensor community for many years. In this paper, we propose a sensor drift correction method to deal with the sensor drift problem. Specifically, we propose a discriminative subspace projection approach for sensor drift reduction in electronic noses.

On the impact of a concave nosed axisymmetric body on a free surface [PDF]
Applied Physics Letters 106, 064101 (2015), 2017 We report on an experimental study of the vertical impact of a concave nosed axisymmetric body on a free surface. Previous studies have shown that bodies with a convex nose, like a sphere, produce a well defined splash with a relatively large cavity behind the model. In contrast, we find that with a concave nose, there is hardly a splash and the cavity

Multi-Stage Feature Selection Based Intelligent Classifier for Classification of Incipient Stage Fire in Building [PDF]
Sensors 2016, 16, 31, 2017 In this study, an early fire detection algorithm has been proposed based on low cost array sensing system, utilizing gas sensors, dust particles and ambient sensors such as temperature and humidity sensor. The odor or smell-print emanated from various fire sources and building construction materials at early stage are measured.
