Implementing A Street And Property Identification System: A Case Study Of Accra, Ghana, Grace Akpene Ecklu

Masters Theses

An increasing problem in rapidly growing cities of developing countries is lack of a functional and standardized address system to support management of resources and provision of necessary facilities and services. In Accra, Ghana, previous attempts to develop an address system have been fragmented in nature and largely unsuccessful. This paper examines the reasons why previous attempts have failed and how a physical address system can be successfully implemented within the Ghanaian context. Based on interviews with a City Planner and a sample of residents of Accra, the paper identifies political, administrative, technical and socio-cultural challenges as major gaps which …

Ir-Tree: An Efficient Index For Geographic Document Search, Zhisheng Li, Ken C. K. Lee, Baihua Zheng, Wang-Chien Lee, Dik Lun Lee, Xufa Wang

Research Collection School Of Computing and Information Systems

Given a geographic query that is composed of query keywords and a location, a geographic search engine retrieves documents that are the most textually and spatially relevant to the query keywords and the location, respectively, and ranks the retrieved documents according to their joint textual and spatial relevances to the query. The lack of an efficient index that can simultaneously handle both the textual and spatial aspects of the documents makes existing geographic search engines inefficient in answering geographic queries. In this paper, we propose an efficient index, called IR-tree, that together with a top-k document search algorithm facilitates four …

Design And Demonstration Of A Miniature Lidar System For Rover Applications, Benjamin Robinson

Electrical & Computer Engineering Theses & Dissertations

Public awareness of harmful human environmental effects such as global warming has increased greatly in recent years and researchers have increased their efforts in gaining more knowledge about the Earth's atmosphere. Natural and man-made processes pose threats lo the environment and human life, so knowledge of all atmospheric processes is necessary. Ozone and aerosols are important factors in many atmospheric processes and active remote sensing techniques provide a way lo analyze their quantity and distribution.

A compact ground-based lidar system for a robotic platform meant for atmospheric aerosol measurements was designed, tested, and evaluated. The system will eventually be deployed …

Increasing Efficiency In Boundary Security With Wireless Sensor Networks And Geospatial Information Systems Using Homology Theory, Luis Berumen^, Eric Chaidez^, Hamide Dogan*, Jose Gerardo Rosiles**

COURI Symposium Abstracts, Spring 2011

As part of an institutional investigation, we attempt to address the challenges the US customs and Border protection agency faces in the El Paso region. Our research focuses on defining a system for the surveillance application, and the use of mathematical models employed to achieve a greater efficiency of such architecture. With the use of the defined system, we apply homology theory through the algebraic process of topology, to accomplish an independent coordinate-free based system, which covers the surveillance area, with lesser quantity of sensor nodes. Our architecture makes the use of an operating system for wireless sensor networks; TinyOS, …

Integrating Values And Ethics Into Wildlife Policy And Management—Lessons From North America, Camilla H. Fox, Marc Bekoff

Conservation Collection

Few animals provoke as wide a range of emotions as wolves. Some see wolves as icons of a lost wilderness; others see them as intruders. As the battle continues between wolf proponents and opponents, finding solutions that resolve conflicts while supporting the integrity of nature is challenging. In this essay we argue that we need to make room for wolves and other native carnivores who are re-colonizing areas from which they were extirpated. Strategies that foster coexistence are necessary and wildlife agencies must consider all stakeholders and invest adequate resources to inform the public about how to mitigate conflicts between …

Factors Of Environmental Sustainability For Africa, Asia, And Latin America, Jacob Converse

Political Science Theses and Capstones

This study incorporates and analyzes several theories in regards to what causes countries to perform in an environmentally sustainable manner. This has been and is becoming an increasingly important and debated topic due to the ever increasing interest and concern about global environmental challenges. This issue has been examined through a variety of different lenses including economic, socio-political, and geographical perspectives and they have an assortment of results. One such existing finding suggests that the best way to improve a country’s environmental sustainability is to first focus on improving the gross domestic product which will eventually allow changes to take …

Growing Conflict: Agriculture, Innovation, And Immigration In San Luis Obispo County, 1837–1937, Douglas P. Jenzen

Master's Theses

The history of San Luis Obispo and its surrounding areas is complex. Agriculture, innovation, and immigration have all contributed to the formation of the region. The Spanish, Mexican, and early American periods established the framework successive waves of immigrants had to live within. Native Americans and immigrants from China, Portugal, Switzerland, Japan, the Philippines, and other regions of the United States have all toiled in the fields and contributed to America’s tables at various points throughout county history. Many contingencies determined the treatment of successive waves of immigrants. Growth and development are taking place at exponential rates on the very …

Rape As A Weapon Of War In The Democratic Republic Of The Congo, Carly Brown

Social Sciences

The Democratic Republic of the Congo has been appropriately acknowledged as "the rape capital of the world." While the country has been trapped in conflict, the use of rape as a weapon of war has been rampant and unyielding. The sexual violence inflicted upon women has been nothing less than brutal and destructive, physically, socially, and psychologically. This paper analyzes the use of rape as a weapon of war in the Congo, taking into context the ongoing war, cultural and social situations that facilitate its existence, and the many consequences the victims are forced to endure.

Enso And Iod Teleconnections For African Ecosystems: Evidence Of Destructive Interference Between Climate Oscillations, Christopher A. Williams, N. P. Hanan

Geography

Rainfall and vegetation across Africa are known to resonate with the coupled ocean-atmosphere phenomena of El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). However, the regional-scale implications of sea surface temperature variability for Africa's photosyntheis have received little focused attention, particularly in the case of IOD. Furthermore, studies exploring the interactive effects of ENSO and IOD when coincident are lacking. This analysis uses remotely sensed vegetation change plus a land surface model driven with observed meteorology to investigate how rainfall, vegetation, and photosynthesis across Africa respond to these climate oscillations. In addition to the relatively well-known ENSO …

Paper Fish And Policy Conflict: Catch Shares And Ecosystem-Based Management In Maine’S Groundfishery, Jennifer F. Brewer

Geography

The National Oceanic and Atmospheric Administration professes support for ecosystembased fisheries management, as mandated by Congress in the Fishery Conservation and Management Act, and as endorsed by the Obama Administration’s national ocean policy. Nonetheless, driving agency policies, including catch shares and fishing quotas, focus principally on individual species, diverting attention from ecosystem considerations such as habitat, migratory patterns, trophic relationships, fishing gear, and firmlevel decision making. Environmental non-governmental organization (ENGO) agendas manifest similar inconsistencies. A case study of Maine’s groundfishery demonstrates implications of this policy conflict at the local level. There, multigenerational fishing villages have historically pursued diversified and adaptive …
