This paper analyzed the potential implementation of renewable hybrid wind/diesel energy system in Pemanggil Island, Malaysia. National Renewable Energy Laboratory's (NREL) HOMER software was used to perform the techno economic feasibility of hybrid wind/diesel energy system. The investigation demonstrated ...
We present a sliding mode based strategy for navigation of a unicycle-like robot to the target through a dynamic environment cluttered with moving and deforming obstacles. The proposed strategy is based on properly switching between moves to the target in straight lines and sliding-mode based bypasses ...
A fundamental question in ecology is whether microorganisms follow the same patterns as multicellular organisms when it comes to population structure and levels of genetic diversity. Enormous population sizes, predominately asexual reproduction and presumably high dispersal because of small body size ...
Aiming directly at addressing the contradition between fishing-boat weather report machines' shortcomings and the request for timely and exact weather report. This thesis poses a weather report machines' program which bases on the GPRS. The program mainly researches the key technology of meteorological ...
In this paper, emergy analysis method is used to evaluate the performance and development of agriculture in Tarim River Basin for the period from 1988 to 2008. The results showed that the total and purchased emergy inputs were increasing steadily, and agriculture system depended on non-renewable heavily ...
Appropriate values for information resources and services need to be evaluated before these values and information resources are exchanged to circulate the information resources more smoothly. A local currency is suitable for financial settlement among members of a community. As previous studies treated ...
In January 2011, a trout farm manager in Kentucky lost his life when he became entangled in a power-take-off connected to a posthole digger ("Green County man," 2011). He was constructing a fence on the farm. Later, in May 2011, an experienced diver drowned while tending fish cages offshore under about ...
Temporary water bodies are important freshwater habitats in the arid zone of Australia. They harbor a distinct fauna and provide important feeding and breeding grounds for water birds. This paper assesses, on the basis of haplotype networks, analyses of molecular variation and relaxed molecular clock ...
Population density is an ecological variable that is hypothesized to be a major agent of selection on offspring size. In high-density populations, high levels of intraspecific competition are expected to favor the production of larger offspring. In contrast, lower levels of intraspecific competition ...
Coastal upwelling is a wind-driven ocean process. It brings cooler, saltier, and usually nutrient-rich deep water upward to replace surface water displaced offshore due to Ekman transport. The nutrients carried up by upwelling are important for primary production and fisheries. Ocean life can aggregate ...
Nonlinear acoustics allows for applications like tissue harmonic imaging in medicine and parametric arrays in underwater acoustics. Mainstream sonars transmit and receive signals at the same frequency and up to now energy transferred to higher harmonic frequencies has been mainly seen as a disturbance ...
Synthetic Aperture Radar systems are powerful observation tools for maritime surveillance applications such as fisheries monitoring or pirates detection and oil slick detection. It is an important problem that has not been completely solved. The Demonstrator of Maritime SAR Applications (DeMSAR) is ...
Identification and assessment of objects are key capabilities of surveillance and information systems for maritime environments. Bayesian methodology provides established instruments for fusion of uncertain identification and assessment indications from various information sources. Particularly, Bayesian ...
Presents the table of contents of the proceedings.
High voltage ceramic (porcelain) insulators of transmission line and power transformers are facing a major problem of contamination. This contamination is location dependent and is from various sources like desert, sea, industry, UV radiations etc. In this paper we report structural, hydrophobic and ...
In recent years, coral bleaching is becoming one of the environmental problems all over the world. In order to monitor this bleaching, remote sensing is expected as a effective tool. Although existing multispectral imager can detect coral bleaching, it cannot detect whether coral became death or living ...
Background The loss of phenotypic characters is a common feature of evolution. Cave organisms provide excellent models for investigating the underlying patterns and processes governing the evolutionary loss of phenotypic traits. The blind Mexican cavefish, Astyanax mexicanus, represents a particularly ...
The surface of many marine organisms is colonized by complex communities of microbes, yet our understanding of the diversity and role of host-associated microbes is still limited. We investigated the association between Ectopleura crocea (a colonial hydroid distributed worldwide in temperate waters) ...
The complete mitochondrial DNA (mtDNA) of Gracilariopsis lemaneiformis was sequenced (25883 bp) and mapped to a circular model. The A+T composition was 72.5%. Forty six genes and two potentially functional open reading frames were identified. They include 24 protein-coding genes, 2 rRNA genes, 20 tRNA ...
Background Cephalopoda are a class of Mollusca species found in all the world's oceans. They are an important model organism in neurobiology. Unfortunately, the lack of neuronal molecular sequences, such as ESTs, transcriptomic or genomic information, has limited the development of molecular neurobiology ...
