  • Digital Elevation Model (DEM) is an important component of GIS applications in many socio-economic areas. Especially, DEM has a very important role in monitoring and managing natural resources, preventing natural hazards, and supporting spatial decision making. Usually, DEM is built by interpolation from a limited set of sample points. Thus, the accuracy of the DEM is depended on the used interpolation method.

  • Cua Viet is the Thach Han river’s mouth. It is quite big estuary that is located in the central coastal province of Quang Tri. In which, Cua Viet port plays an important role for water transport and commerce of the province. In recent years, accretion and erosion have occurred increasingly in term of scale and intensity. In addition, estuarine access channels suffer severely from sedimentation.

  • Abstract. In this study, we assessed the impact of sea level rise, one of the most ascertained consequences of global climate change, for water levels in the Vietnamese Mekong Delta (VMD). We used a hydraulic model to compute water levels from August to November – when flooding is presently critical – under sea level rise scenarios of 20 cm (= 20) and 45

  • Research over the past decade has demonstrated the feasibility of extracting topographic information of hydrological interest directly from digital elevation models (DEM). Techniques are available for extracting slope properties, catchment areas, drainage divides, channel networks and other data (Jenson and Domingue, 1988; Mark, 1988; Moore et al., 1991; Martz and Garbrecht, 1992). These techniques are faster and provide more precise and reproducible measurements than traditional manual techniques applied to topographic maps (Tribe, 1991)....

  • The twentieth century elevated our understanding of the Universe from its early stages to what it is today and what is to become of it. Cosmology is the weapon that utilizes all the scientific tools that we have created to feel less lost in the immensity of our Universe. The standard model is the theory that explains the best what we observe. Even with all the successes that this theory had, two main questions are still to be answered: What is the nature of dark matter and dark energy? This book attempts to understand these questions while giving some of...

  • The revised and updated Second Edition includes new subchapters on evolutionary Blackman-Tukey, Lomb-Scargle and Wavelet powerspectral analyses (Chapters 5.6 – 5.8), statistical analysis of point distributions and digital elevation models (Chapters 7.9 and 7.10), and a new chapter on the statistical analysis of directional data (Chapter 10). Whereas undergradu- ates participating in a course on data analysis might go through the entire book, the more experienced reader will use only one particular method to solve a specifi c problem.

  • The second group was formed of men with a suspicion of prostate cancer based on an elevated serum PSA and/or abnormal digital rectal examination, and the blood sample taken immediately before the prostate biopsy. The presence or absence of CPCs was to be compared with the biopsy results, the Gleason score, percent of sample infiltrated with cancer, and number of positive cores. The sensitivity, specificity, positive and negative predictive values were to be calculated. In men with a false negative test the details of the cancer detected would be evaluated.

  • Critical loads are typically expressed as deposition loading rates of one or more pollutants in amount per area per year (e.g., kilo- grams per hectare per year (kg/ha/yr)). Critical loads are based on changes to specific biological or chemical indicators such as species composition of a given ecosystem (e.g., grassland) or biotic community (e.g., understory plants or tree-dwelling lichens) or acid neu- tralizing capacity (ANC) in soils, streams or lakes. Because different sensitive receptors (e.g.

  • We are living on an increasingly urban planet. In 2008 we passed the halfway mark—50% of the world’s population now live in cities, and that percentage is projected to increase to 70% by 2050. There is no turning back the urban trend. Yet ironically we have as a species yet to successfully design and plan cities that will accommodate our economic and demographic needs while uplifting and elevating us, and protect, restore, and nurture the planet and its natural systems.

  • When choosing a photograph for the tilt-shift effect, bear in mind that you want to give the impression of a miniature model. Miniature models are usually viewed from above so try and choose a photo with an elevated viewpoint. Buildings, roads, traffic and railways are excellent choices but make sure there is a reasonable wide angle of view.

  • One feature of this model is that strokes develop spontaneously following severe hypertension (more than 150 mmHg). Therefore, in SHRSP, because strokes develop after the onset of elevated blood pressure, elevated blood pressure is considered to be the most critical factor for stroke induction. However, interestingly, the neuronal cells of this model exhibit a great vulnerability compared with normal control WKY/Izm rats during the reoxygenation conditions following hypoxia (Tagami et al., 1998; Yamagata et al., 2010c).

  • Many analysts also contend that credit scores, which weigh items that signify financial distress or limited availability of credit, are correlated with minority status. Significant debate has continued about lending practices that restrict access to credit in minority communities—a factor that could have a significant impact on insurance-based credit scores.

  • A good example of this merging and perceptual elevation is Dunescape, the project that won MoMAI P.S.l's Young Architects Program the year before Massie's Playa Urbana/Urban Beach. Designed and built by by SHoP Architects, Dunescape is an architecturalized landscape built completely as a series of parallel, stacked dimensional lumber. While manual labor was required to cut, assemble, and fasten the pieces in the actual construction, the methodology was completely digitally driven.
