Force-directed approaches to sensor localization
(SIAM, 2006)
We consider the centralized, anchor-free sensor localization problem. We consider the case where the sensor network reports range information and the case where in addition to the range, we also have angular information ...
A robust localization framework to handle noisy measurements in wireless sensor networks
(IEEE, 2009-09-14)
We construct a robust localization framework to handle noisy measurements in wireless sensor networks. Traditionally many approaches employ the distance information gathered from ranging devices of the sensor nodes to ...
Fully decentralized, collaborative multilateration primitives for uniquely localizing WSNs
(Springer-Verlag Berlin, 2009)
We provide primitives for uniquely localizing WSN nodes. The goal is to maximize the number of uniquely localized nodes assuming a fully decentralized model of computation. Each node constructs a cluster of its own and ...
Cluster based sensor scheduling in a target tracking application with particle filtering
(IEEE, 2007)
In multi-sensor applications management of sensors is necessary for the classification of data they produce and for the efficient use of sensors as well. One of the important aspects in sensor management is the sensor ...
A new algorithm for high speed speech and audio coding
(IEEE, 2007)
In this work, a new mathematical modeling approach is proposed for the representation of the speech and audio signals. This approach is based on the generation of the so called Predefined Signature Sequence (PSS) and ...
A cost-efficient bit-serial architecture for sub-pixel motion estimation of H.264/AVC
(IEEE Computer Soc, 2008)
This paper presents a new VLSI architecture for sub-pixel motion estimation in H.264/AVC encoder. It is based on an interpolation free algorithm that causes a high level reduction on memory requirement, hardware resources ...
Annular CMUT arrays for side looking intravascular ultrasound imaging
(IEEE, 2007)
Although side looking intravascular ultrasound (SL-IVUS) imaging systems using single element piezoelectric transducers set the resolution standard in the assessment of the extent of coronary artery disease, improvements ...
Optimal investment levels to eliminate inventory inaccuracy in a two-level supply chain
(Istanbul Technical Univ, 2007)
Inventory inaccuracy is a major problem in supply chains. RFID technology is anticipated to alleviate this problem at the expense of the required hardware and software investment. For a supply chain consisting of single ...
Forward-looking IVUS imaging using a dual-annular ring CMUT array: Experimental results
(IEEE, 2007)
This paper presents the experimental results on forward-looking Intravascular ultrasound (FL-IVUS) using dual-annular-ring CMUT arrays. The array has a diameter of 1mm including bondpads which consists of separate, concentric ...
An algorithm and its architecture for half-pixel variable block size motion estimation
(IEEE, 2007)
This paper presents an accurate half-pixel variable block size motion estimation algorithm and its hardware architecture. The proposed algorithm does not require interpolation of the reference frame pixels and has near ...
