wetlands in the lower reaches of songhua river (lrsr), northeast china, are rich in biodiversityand natural resources, which provide crucial staging and wintering habitats for various endangered species.however, in the past five decades, the size of this wetland area has decreased, and its quality has deteriorated because of increased natural and human activities. wetland restoration is critica...

In recent years, approaches based on machine learning have achieved state-of-theart performance on image restoration problems. Successful approaches include both generative models of natural images as well as discriminative training of deep neural networks. Discriminative training of feed forward architectures allows explicit control over the computational cost of performing restoration and the...

This paper presents a new approach to blind image deconvolution based on soft-decision blur identification and hierarchical neural networks. Traditional blind algorithms require a hard-decision on whether the blur satisfies a parametric form before their formulations. As the blurring function is usually unknown a priori, this precondition inhibits the incorporation of parametric blur knowledge ...

Degradation in images is usually undesirable but unavoidable. The most common cause of this is motion. Given only the image degraded by motion blur, blind restoration aims to determine the original unblurred image and the blurring function. This paper proposes an approach to simultaneously determine these two quantities by utilising a reference point spread function (RPSF) as a learning basis i...

The exponentially growing number of Internet users armed with emerging multimedia Internet applications is continuously thirsty for more network capacity. Wavelengthdivision multiplexing networks that directly support IP — the so-called IP over WDM architecture — have the appropriate characteristics to quench this bandwidth thirst. As everyday life increasingly relies on telecommunication servi...

High-strength all-ceramic materials are commonly used in dentistry. When complications occur in an all-ceramic restoration, the restoration is usually replaced. This article describes the time-saving ability and cost-effectiveness of this novel technique for the addition of a pontic in two complicated clinical cases. Turkom-Cera(™) [Turkom-Ceramic (M) Sdn. Bhd.] with aluminum oxide (99.98%) is ...

BACKGROUND The changing oral health needs in South Africa require that both the teaching and clinical techniques of atraumatic restorative treatment (ART) form a part of the restorative undergraduate curriculum. OBJECTIVE This study was undertaken to establish and compare the estimated costing of an amalgam, composite resin and ART restoration within the Board of Health Funders (BHF) recommen...

Production, maintenance, and quality are often modeled as separate problems, despite the strong link that exists between these primary components of any manufacturing system. This paper deals with an integrated approach for the joint optimization of production-inventory control and preventive maintenance policy for a manufacturing cell comprising an imperfect process where the ‘in-control’ peri...

During the last years, several types of network control and restoration techniques have been proposed and discussed. However it was evaluated that a single restoration technique in high-speed networks cannot cover the needs for control, survivability and economical spare channel assignment. This is due to the fact that each technique has its own feature and properties in terms of restoration ti...
