Finite perturbation analysis methods for optimization of inventory systems with non-stationary Markov-modulated demand and partial information
(Bilkent University, 2018-02)The state of the economy may fluctuate due to several factors, and the customer demand is a affected from the fluctuations of the state of the economy. Although the inventory holders can predict the state of the ... -
Fire detection algorithms using multimodal signal and image analysis
(Bilkent University, 2009)Dynamic textures are common in natural scenes. Examples of dynamic textures in video include fire, smoke, clouds, volatile organic compound (VOC) plumes in infra-red (IR) videos, trees in the wind, sea and ocean waves, ... -
Ionogram scaling using Hidden Markov Models
(Institute of Electrical and Electronics Engineers, 2018)In this paper, a novel method for electron density reconstruction using ionosonde data is proposed. Proposed technique uses Hidden Markov Models for extracting echoes that provides valuable information about electron density ... -
Pyroelectric infrared (PIR) sensor based event detection
(Bilkent University, 2009)Pyroelectric Infra-red (PIR) sensors have been extensively used in indoor and outdoor applications as they are low cost, easy to use and widely available. PIR sensors respond to IR radiating objects moving in its viewing ...
