The optimal control literature is dominated by standard problems in which the system cost functional is expressed in the well-known Bolza form. Such Bolza cost functionals consist of two terms: a Mayer term (which depends solely on the final state reached by the system) and a Lagrange integral term ...
Purpose of this paper is to introduce a new technique for denoising underwater acoustic signal affected by ambient noise. Ambient noise is nonstationary and unwanted background noise caused due to manmade or natural causes. In practical application it is essential to denoise underwater acoustic signal, ...
Motor neuron disorders (MNDs) are a clinically heterogeneous group of neurological diseases characterized by progressive degeneration of motor neurons, and share some common pathological pathways. Despite remarkable advances in our understanding of these diseases, no curative treatment for MNDs exists. ...
Purpose: This paper is directed at gaining an understanding of the internal business logic of an organisation in order to better determine the requirements for a successful customer service initiative in an organisation offering an integrated package of products and services. Problem Investigated: Customer ...
The internet is a rich source of knowledge that is constantly expanding as users generate content which needs to be organized and classified. Future versions of the web are likely to include intelligent software agents capable of using metadata to understand complex relationships and better support ...
Submarine optical networks play a major part in international telecommunication networks, with over 95% of all transcontinental communications traffic being carried by submarine cables. This makes submarine optical networks highly important, both from economical, as well as the legal point of view. ...
After decades of strict pollution control and municipal sewage treatment, the water quality of the Tanshui River increased significantly after pollution mitigation as indicated by the River Pollution Index (RPI). The pollution level of the estuarine region decreased from severe pollution to mostly moderately ...
Background Little is known regarding risk factors for lymphatic filariasis (LF) in Central Africa. We studied the epidemiology of LF in an endemic village in the Republic of Congo. Methods Dependent variables were Wuchereria bancrofti antigenemia (ICT card test) and microfilaremia (night blood smears). ...
Much research on coral reefs has documented differential declines in coral and associated organisms. In order to contextualise this general degradation, research on community composition is necessary in the context of varied disturbance histories and the biological processes and physical features thought ...
Security and disaster alert dissemination showcase the key challenges faced by the fishing industry, mainly due to the lack of reliable communication means, and can pose serious threats to the lives of the fishermen. The fishing vessels, equipped with appropriate transceivers, can be considered as MANETs ...
In this study the effects of water salinity on serum total protein and its components in grass carp were investigated. The aim of this study was to determine the effect of salinity tolerance of fish on total serum protein level and its components as an indicator of liver and kidney activity. One hundred ...
Background: Aeromonas hydrophila cause one of the most important diseases in fishes and lead to economic losses, and may be contaminated human beings. Objectives: The current research aimed to investigate the anti-bacterial activity shown by the extracts prepared from different parts of Olea europea, ...
Biogas slurry has become a serious pollution problem and anaerobic digestion is widely applied to pig manure treatment for environmental protection and energy recovery. To evaluate environmental risk of the emission of biogas slurry, luminescent bacteria (Vibrio fischeri), larvae and embryos of zebrafish ...
Ocean acidification (OA) is occurring across a backdrop of concurrent environmental changes that may in turn influence species' responses to OA. Temperature affects many fundamental biological processes and governs key reactions in the seawater carbonate system. It therefore has the potential to offset ...
Animal colors play important roles in communication, ecological interactions and speciation. Carotenoid pigments are responsible for many yellow, orange and red hues in animals. Whereas extensive knowledge on the proximate mechanisms underlying carotenoid coloration in birds has led to testable hypotheses ...
The pixel-based classification of remotely sensed images always produces a large amount of “speckled” or “salt and pepper” noises. Both post-classification smoothing and object-based classification techniques have been proposed to tackle this problem. However, most of them are not adequate to deal with ...
The massive green tide occurred in the summer of 2008 in the coastal waters of Qingdao where the Olympic sailing competitions will be held, drew much attention from the international community. A web-based green tide monitoring system was established to routinely monitor the coverage area of green tide ...
Land subsidence in western Taiwan has been an issue since 1970's due to over extraction of ground water for aquaculture. This problem became serious in Yunlin County because high-speed rail way transects the center of land subsidence which may cause safety problem. Leveling survey is applied annually. ...
In this study, a red tide event in 2008 in the Arabian Gulf was monitored and assessed using multi-source satellite imagery, including MODIS, SeaWiFS, and MERIS. Satellite derived chlorophyll-a and enhanced RGB images were used. Satellite observations revealed the bloom extent and evolution during the ...
Our recent study shows that Hyperion data and Hyperspectral Optimization Process Exemplar (HOPE) can effectively retrieve the shallow water depth in the South China Sea. In this study, the HJ-1A/HSI and EO-1/Hyperion remote sensing reflectance (Rrs) is simulated by the ocean radiative transfer software ...
