Reducing water imbalance in land data assimilation: Ensemble filtering without perturbed observations
Yılmaz, Mustafa Tuğrul; Yilmaz, M. Tugrul (American Meteorological Society, 2012-02-01)
It is well known that the ensemble Kalman filter (EnKF) requires updating each ensemble member with perturbed observations in order to produce the proper analysis-error covariances. While increased accuracy in a mean square sense may be preferable in many applications, less accuracy might be preferable in other applications, especially if the variables being assimilated obey certain conservation laws. In land data assimilation, for instance, the update in soil moisture often produces a water balance residua...
Reducing the cost of electric transmission and distribution systems with wind generation by means of energy storage and demand side management
Bildirici, Mert; Keysan, Ozan; Department of Electrical and Electronics Engineering (2018)
Today, wind energy is the most popular renewable energy source and share of wind generation in overall electric power generation is expected to grow significantly for the next years. Considering this increase, energy balance problem will become harder to achieve due to unpredictable and varying nature of wind power. In order to handle with the negative impacts of wind power, it is essential to provide flexibility to power systems. This thesis focuses on the transmission system upgrade deferral for a hypothe...

Reducing MIMO detection complexity via hierarchical modulation /
Uğur, Yiğit; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2014)
This work considers multiple-inputmultiple-output (MIMO) communication systems using hierarchical modulation. A disadvantage of the maximum-likelihood (ML) MIMO detector is that its computational complexity increases exponentially with the number of transmit antennas. To reduce complexity, we propose a hierarchical modulation scheme to be used in MIMO transmission where base and enhancement layers are incorporated. In the proposed receiver, the base layer is detected first with a minimum mean square error (...
Reducing the question burden of patient reported outcome measures using Bayesian networks
Yuceturk, Hakan; Gulle, Halime; TUNCER ŞAKAR, CEREN; Joyner, Christopher; Marsh, William; ÜNAL, EDİBE; Morrissey, Dylan; Yet, Barbaros (2022-11-01)
Patient Reported Outcome Measures (PROMs) are questionnaires completed by patients about aspects of their health status. They are a vital part of learning health systems as they are the primary source of information about important outcomes that are best assessed by patients such as pain, disability, anxiety and depression. The volume of questions can easily become burdensome. Previous techniques reduced this burden by dynamically selecting questions from question item banks which are specifically built for...
