Long-term forecasting is a big challenge for the regional modelling, since only a few years of panel data are available on a regional basis. Furthermore, traffic dependent models must be developed to explore the sensitivity of travelling times on the socio-demographic variables of a region. Using the sophisticated model choice procedure BMA (Bayesian model averaging, see Raftery et al. 1997) fo...

Model uncertainty remains a challenge to researchers in different applications. When many competing models are available for estimation, and without enough guidance from theory, model averaging represents an alternative to model selection. Despite model averaging approaches have been present in statistics for many years, only recently they are starting to receive attention in applications. The ...

Several variants of Bayesian Model Averaging (BMA) are described and evaluated on a model library of heterogeneous classifiers, and compared to other classifier combination methods. In particular, embedded cross-validation is investigated as a technique for reducing overfitting in BMA.

The low-energy characteristics of wireless sensor networks (WSNs) pose a great design challenge for MAC protocol design. Recent studies have proposed different clusterbased MAC protocols. In [1], we proposed an intra-cluster communication bit-map-assisted (BMA) MAC protocol for clusterbased WSNs. BMA is intended for event-driven applications, where sensor nodes transmit data to the cluster head...

for an infant the parents must ultimately decide"-with the doctor helping the parents to understand the choices.5 In their responses to the present case (22 August, p 567) both the BMA and the British Paediatric Association have reiterated these principles. We believe that in the absence of a clear code to which society adheres there is no justification for usurping parents' rights, or for beli...

typographical data entry errors and incomplete documents, produce imperfect records in real world databases. these errors generate distinct records which belong to the same entity. the aim of approximate record matching is to find multiple records which belong to an entity. in this paper, an algorithm for approximate record matching is proposed that can be adapted automatically with input error...

The formal Presidential regalia is an ornate chain from which is suspended the badge of the British Medical Association and below it the badge of the Society (Figure 1 ). The large badge is engraved on the front 'British Medical Association Belfast 1909' (Figure 2). It was presented by the medical profession of Ulster to Sir William Whitla who was President of the BMA when it met in Belfast in ...

Improvements in de-interlacing algorithms are fundamental to explore image quality potential on modern TV screen technologies. This paper presents a true motion vector verification algorithm based on multi temporal block matching strategy, applied to video de-interlacing. During field scanning, a block of pixels is selected, then a block with the same reference coordinates is extracted but in t...

T he motion estimation and compensation technique is widely used for video coding applications but the real-time motion estimation is not easy due to its enormous computations. In this paper, a new adaptive reduction of search area for the blockmatching algorithm is presented to reduce the computational complexity of the full search blockmatching algorithm for low bit-rate video coding. The pro...

A video sequence consists of a series of frames. In order to compress the video for efficient storage and transmission, the temporal redundancy among adjacent frames must be exploited. A frame is selected as reference frame and subsequent frames are predicted from the reference frame using a technique known as motion estimation. Real videos contain a mixture of motions with slow and fast conten...
