Volumetric imaging using fan-beam scanning with reduced redundancy 2D arrays
(IEEE, 2006)
Phased array processing with a fully populated 2D array produces the best image quality but requires excessive number of active parallel front-end channels. Here we explore four array designs with reduced redundancy in ...
Mixed-method validation of pedagogical concepts for an intercultural online learning environment: a case study
(Assoc Computing Machinery, 2007)
The rise of social software poses the challenges to the design and evaluation of a pedagogically sound online learning environment (OLE). Our OLE addresses these challenges by the integration of three pedagogical concepts ...
Virtual team effectiveness using dyadic teams
(IEEE, 2007)
The importance of effectiveness for virtual teamwork continues to gain momentum as technology and globalization of work accelerate. The implementation of virtual teams provides one approach to enhance competitiveness, ...
H.264 video kodlamada çerçeve seviyesinde karmaşıklık kontrolü
(IEEE, 2007)
H.264 kodlama standardı, değişken blok boyutlu makroblok bölüntüleri kullanan çok sayıda farklı çerçeveler arası kestirim kipini desteklemektedir. Ne var ki, her olası bölüntü için eniyi devinim vektörlerini aramanın ...
Crossing minimization in weighted bipartite graphs
(Springer, 2007)
Given a bipartite graph G = (L-0, L-1, E) and a fixed ordering of the nodes in L-0, the problem of finding an ordering of the nodes in L-1 that minimizes the number of crossings has received much attention in literature. ...
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 ...
Comparison of evolutionary techniques for Value-at-Risk calculation
(Springer-Verlag Berlin, 2007)
The Value-at-Risk (VaR) approach has been used for measuring and controlling the market risks in financial institutions. Studies show that the t-distribution is more suited to representing the financial asset returns in ...
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 ...
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 ...
