Leading market analysts such as Gartner, Forrester Research and IDC expect again for 2012 an increase of global information technology (IT) spending between 3.7% and 6.9% compared to 2011. This trend emphasises the fact that ensuring the effectiveness and efficiency of IT or IT evaluation is a substantial task of strategic IT management. Weighing costs and benefits is already a real challenge f...

A Service represents an underlying capability offered by a service provider. A service description describes two facets of a service – the service functionality (capability onoffer) and the terms at which the service is offered (terms of offer). The capability onoffer satisfies the goal of a service consumer under the constraints of the terms of offer. Service Policies are used to define the te...

Visual impairment is a significant limitation of visual capability resulting from either disease or trauma, which cannot be restored by conventional means, such as refractive correction or medication. Ocular disorders, which can lead to visual impairments include retinal degeneration, albinism, cataracts, glaucoma, corneal disorders, diabetic retinopathy, congenital disorders, infection, and ma...

Incremental learning of visual categories denotes the capability of a visual perceptual system to build up an increasing repertoire of visual concepts based on a sequence of experiences. A visual category is here defined as a possibly large group of individual objects that share similar properties like shape, appearance, or color. Biological visual systems achieve this function very efficiently...

With the development of wireless network and the improvement of mobile device capability, video streaming is more and more widespread in such an environment. Under the condition of limited resource and inherent constraints, appropriate video adaptations have become one of the most important and challenging issues in wireless multimedia applications. In this paper, we propose a novel content-awa...

This paper presents an attractive position-based visual sewoing approach for camera-in-hand robotic systems. The major contribution of this work is in devising an elegant and pragmatic approach for 3 0 visual tracking. The proposed Modijied Smith Predictor (MSP)-DeMenthon-Horaud (DH) visual sewoing system has shown to be reliable and yielded good target tracking performance. It d@er from the ot...

The exact roles of the medial prefrontal cortex (mPFC) in conditional choice behavior are unknown and a visual contextual response selection task was used for examining the issue. Inactivation of the mPFC severely disrupted performance in the task. mPFC inactivations, however, did not disrupt the capability of perceptual discrimination for visual stimuli. Normal response selection was also obse...

This conceptual paper in sustainable business research introduces a business sustainability maturity model as an innovative solution to support companies move towards sustainable development. Such model offers the possibility for each firm to individually assess its position regarding five sustainability maturity levels and, as a consequence, build a tailored as well as a common strategy along ...

UNLABELLED How neuronal ensembles compute information is actively studied in early visual cortex. Much less is known about how local ensembles function in inferior temporal (IT) cortex, the last stage of the ventral visual pathway that supports visual recognition. Previous reports suggested that nearby neurons carry information mostly independently, supporting efficient processing (Barlow, 1961...
