We present intra-, interand cross-cultural classifications of vocal expressions. Stimuli were selected from the VENEC corpus and consisted of portrayals of 11 emotions, each expressed with 3 levels of intensity. Classification (nu-SVM) was based on acoustic measures related to pitch, intensity, formants, voice source and duration. Results showed that mean recall across emotions was around 2.4-3...

Research in the field of plant biology has recently demonstrated that inter- and intra-specific interactions belowground can dramatically alter root growth. Our aim was to answer questions related to the effect of inter- vs. intra-specific interactions on the growth and utilization of undisturbed space by fine roots within three dimensions (3D) using micro X-ray computed tomography. To achieve ...

Character recognition in natural scenes continues to represent a formidable challenge in computer vision. Traditional optical character recognition (OCR) methods fail to perform well on characters from scene text owing to a variety of difficulties in background clutter, binarisation, and arbitrary skew. Further, English characters group into only 62 classes whereas many of the world’s languages...

Selecting a low dimensional feature subspace from thousands of features is a key phenomenon for optimal classification. Linear Discriminant Analysis (LDA) is a basic well recognized supervised classifier that is effectively employed for classification. However, two problems arise in intra class during discriminant analysis. Firstly, in training phase the number of samples in intra class is smal...

Open reduction and internal fixation has been widely used to treat displaced intra-articular calcaneus fractures in children. However, the complications of surgical trauma and the wound created through the extended lateral approach cannot be ignored. This study analyzed the outcomes of displaced intra-articular calcaneal fractures in children treated with closed reduction and percutaneous fixat...

BACKGROUND Many biobanks have struggled to deliver on the high expectations and claims made for them because of insufficient samples, inadequate infrastructure, cost of establishing and maintaining a large enough resource over the long term, and satisfying legal, ethics and governance requirements. Increasingly, networks have formed to help with the collection, processing, storage, advertising,...
