HNLC was designed to contribute to science, mathematics, engineering, and technology system reform efforts of the Hawaiʻi Department of Education. HNLC's website, hnle.org, was designed to support the HNLC initiative and serve HNLC participants as an online community space. Results indicate that participants have not adopted hnle.org as a tool for their ownuse, and are instead using hnle.org almost exclusively during highly structured workshops where hnle.org use is required. Active participation in the online community is rare. Participant interviews and focus groups revealed that there exists a disconnect between the stated needs of educators and the offerings of hnle.org. Participants were primarily concerned with uses of technology by their students, while hnle.org is targeted to educators' own professional development efforts. xi, 109 leaves Mon, 01 Dec 2003 00:00:00 GMT http://hdl.handle.net/10125/7028 2003-12-01T00:00:00Z Doane, William EJ http://hdl.handle.net/10125/6971 The Multi-path On-demand Routing (MOR) Protocol is an on-demand, load balancing routing protocol designed for the Pods project at the University of Hawaiʻi at Manoa. Pods is a Remote Ecological Micro-Sensor Network where robustness and energy efficiency are high priorities. Pods sensors are wireless and often cannot communicate with a base station directly. MOR addresses these Pods needs through an on-demand routing mechanism using multiple paths where possible. MOR differs from other protocols in the use of a hop-by-hop reliability layer to optimize data delivery in low mobility environments. The reliability layer reroutes packets that fail to transmit (to the next hop) to a different path. Rerouting is possible since MOR utilize gradients for route direction, resulting in non-disjoint multipaths. MOR attempts to lower energy usage by minimizing the number of network floods necessary to establish routes. MOR was compared using simulation with DSR and AODV in reasonable dense and sparse sensor network topologies. MOR showed substantial improvements over DSR and AODV in terms of energy use and data delivery rate. viii, 39 leaves Thu, 01 May 2003 00:00:00 GMT http://hdl.handle.net/10125/6971 2003-05-01T00:00:00Z Chen, Shu Hui http://hdl.handle.net/10125/6967 Unit testing is an important part of software testing that aids in the discovery of bugs sooner in the software development process. Extreme Programming (XP), and its Test First Design technique, relies so heavily upon unit tests that the first code implemented is made up entirely of test cases. Furthermore, XP considers a feature to be completely coded only when all of its test cases pass. However, passing all test cases does not necessarily mean the test cases are good. Extreme Coverage (XC) is a new approach that helps to assess and improve the quality of software by enhancing unit testing. It extends the XP requirement that all test cases must pass with the requirement that all defect-prone testable methods must be invoked by the tests. Furthermore, a set of flexible rules are applied to XC to make it as attractive and light-weight as unit testing is in XP' One example rule is to exclude all methods containing one line of code from analysis. I designed and implemented a new tool, called JBlanket, that automates the XC measurement process similar to the way that JUnit automates unit testing. JBlanket produces HTML reports similar to JUnit reports which inform the user about which methods need to be tested next. In this research, I explore the feasibility of JBlanket, the amount of effort needed to reach and maintain XC, and the impact that knowledge of XC has on system implementation through deployment and evaluation in an academic environment. Results show that most students find JBlanket to be a useful tool in developing their test cases, and that knowledge of XC did influence the manner in which students implemented their systems. However, more studies are needed to conclude precisely how much effort is needed to reach and maintain XC. This research lays the foundation for future research directions. One direction involves increasing its flexibility and value by expanding and refining the rules of XC. Another direction involves tracking XC behavior to find out when it is and is not applicable. xii, 108 leaves Thu, 01 May 2003 00:00:00 GMT http://hdl.handle.net/10125/6967 2003-05-01T00:00:00Z Agustin, Joy M
