With the globalization and rapid development every filed is taking an increasing interest in physical geography and human economics. There is a surging demand for small scale world map in large format...
Thin Layers: Observations of Small-Scale Patterns and Processes in the Upper Ocean
Small-Scale Patterns Processes
2015/8/6
Fore decades, marine scientists have been asking questions about the response of planktonic distributions and processes to physical forcing across a range of temporal and spatial scales. The mismatch ...

Small-Scale Vertical Structures Zooplankton Assemblages
2015/8/6
Observation of aquatic animals in their natural environments remains a major challenge in both biological oceanography and limnology. Critical processes in feeding, reproduction, growth, and predation...
Small-Scale Planktonic Structure: Persistence and Trophic Consequences
Persistence Trophic Consequences
2015/8/6
Most conventional sampling methods limit our ability to resolve planktonic distributions over vertical scales less than a few meters. Estimates of in situ biological rates also are limited by equipmen...
Varied observations over Oregon's continental shelf illustrate the beauty and complexity of geophysical flows in coastal waters. Rapid, creative, and sometimes fortuitous sampling from ships and moori...

Small-scale Sensor Networks Optimization
2015/6/19
The general joint design of the physical, MAC, and routing layers to minimize network energy consumption is complex and hard to solve. Heuristics to compute approximate solutions and high-complexity a...
PHOTOINTERPRETATION AND SMALL SCALE STEREOPLOTTING WITH DIGITALLY RECTIFIED PHOTOGRAPHS WITH GEOMETRICAL CONSTRAINTS1
Architectural photogrammetry self-calibration rectification,

The earliest man-made irrigation systems in recorded history date back to the ancient Egypt and Mesopotamia era. After thousands of years of experience, exploration, and experimenting, mankind have le...
Fruit and Vegetable Marketing for Small-Scale and Part-Time Growers
Fruit and Vegetable Marketing Small-Scale Part-Time Growers
2013/6/28
Marketing is important to all farm enterprises, regardless of size. Small-scale fruit and vegetable growers generally have more difficulty finding established markets; therefore, they usually develop ...
The results of some experiments on convection by surface heating in a simple numerical model for small-scale processes in the dry atmosphere
Numerical Atmospheric Model Finite Difference
2010/12/30
The model described in this paper represents the flow of dry air in one horizontal dimension of domain length 64 km and the vertical dimension of height 16 km (the height of the tropopause in tropical...
The Need to Regularise Activities of Illegal Small-Scale Mining in Ghana: A Focus on the Tarkwa-Dunkwa Highway*
Law Small-Scale Mining Regularise Ghana
2010/12/29
Southwest Ghana is a major gold producing region. The current high gold price has attracted hundreds of unemployed youth to undertake small-scale mining (SSM). Most of these miners operate illegally e...
A new framework for analyzing the effects of small scale inhomogeneities in cosmology
