Open Source Foundations For Spatial Decision Support Systems, Jochen Albrecht Dec 2018

Open Source Foundations For Spatial Decision Support Systems, Jochen Albrecht

Publications and Research

Spatial Decision Support Systems (SDSS) were a hot topic in the 1990s, when researchers tried to imbue GIS with additional decision support features. Successful practical developments such as HAZUS or CommunityViz have since been built, based on commercial desktop software and without much heed for theory other than what underlies their process models. Others, like UrbanSim, have been completely overhauled twice but without much external scrutiny. Both the practical and the theoretical foundations of decision support systems have developed considerably over the past 20 years. This article presents an overview of these developments and then looks at what corresponding tools ...


Smart Iot Sprinkler System, Galib F. Rahman Dec 2018

Smart Iot Sprinkler System, Galib F. Rahman

Publications and Research

The average family spends more than $1000 in water costs per year. One-way water is commonly wasted in many households is via inefficient sprinkler systems for lawns. Current technology has enabled the development of automatic sprinkler systems, which can be preconfigured to operate at desired times of day and intervals. Although these systems may reduce the amount of water utilized overall, they are not weather forecast aware. In situations when rainfall is upcoming the systems still water the lawn. In this project, we plan to implement a smart sprinkler system that has full awareness of upcoming weather and take account ...

Modern marine biologists seeking to study or interact with deep-sea organisms are confronted with few options beyond industrial robotic arms, claws, and suction samplers. This limits biological interactions to a subset of “rugged” and mostly immotile fauna. As the deep sea is one of the most biologically diverse and least studied ecosystems on the planet, there is much room for innovation in facilitating delicate interactions with a multitude of organisms. The biodiversity and physiology of shallow marine systems, such as coral reefs, are common study targets due to the easier nature of access; SCUBA diving allows for in situ delicate ...


An Application Of Game Theory In Distributed Collaborative Decision Making, Angran Xiao Jul 2018

An Application Of Game Theory In Distributed Collaborative Decision Making, Angran Xiao

Publications and Research

In a distributed product realization environment, new paradigms and accompanying software systems are necessary to support the collaborative work of geographically dispersed engineering teams from different disciplines who have different knowledge, experience, tools and resources. To verify the concept of collaboration by separation, we propose a generic information communication medium to enable knowledge representation and exchange between engineering teams, a digital interface. Across digital interfaces, each engineering team maintains its own perspective towards the product realization problem, and each controls a subset of design variables and seeks to maximize its own payoff function subject to individual constraints. Hence, we postulate ...


Tolerance Sensitivity Analysis And Robust Optimal Design Method Of A Surface-Mounted Permanent Magnet Motor By Using A Hybrid Response Surface Method Considering Manufacturing Tolerances, Cha-Seung Jun, Byung-Il Kwon, Ohbong Kwon May 2018

Tolerance Sensitivity Analysis And Robust Optimal Design Method Of A Surface-Mounted Permanent Magnet Motor By Using A Hybrid Response Surface Method Considering Manufacturing Tolerances, Cha-Seung Jun, Byung-Il Kwon, Ohbong Kwon

Publications and Research

This paper presents a robust optimal design method using a hybrid response surface method (H-RSM) which directly finds an optimal point satisfying a target Z-value or a probability of failure. Through three steps, this paper achieves the goal that is to increase the open-circuit airgap flux (OCAF) in a surface-mounted permanent magnet motor and decrease its variation caused by variations of the airgap lengths including an additional one between permanent magnets and rotor back yoke. First, the OCAF equation is derived from the magnetic equivalent circuit (MEC) considering the additional airgap. Then, the equation is validated by comparing its results ...


Solar And Rain Catching Canopy. Urban Oasis, Afolabi Ibitoye, Langston Clark, Elena Zimareva, Evan Banks, Alexander Aptekar May 2018

Solar And Rain Catching Canopy. Urban Oasis, Afolabi Ibitoye, Langston Clark, Elena Zimareva, Evan Banks, Alexander Aptekar

Publications and Research

The Urban Oasis is designed to work within existing “pocket parks” in New York City as a combined rainwater collector, personal electronics charging station and resting designation for New Yorkers. Intended to not only lessen the demand on the city power grid by using renewable energy to charge devices, the urban oasis is also intended to mitigate grey water overfill in New York’s combined sewer system and, in general, serve as a model for responsible environmental stewardship in urban areas.

The important technical aspects of the canopy specifically analyzed were:

a) how much rainwater could the canopy be expected ...


Correlated Network Of Networks Enhances Robustness Against Catastrophic Failures, Byungjoon Min, Muhua Zheng Apr 2018

Correlated Network Of Networks Enhances Robustness Against Catastrophic Failures, Byungjoon Min, Muhua Zheng

Publications and Research

Networks in nature rarely function in isolation but instead interact with one another with a form of a network of networks (NoN). A network of networks with interdependency between distinct networks contains instability of abrupt collapse related to the global rule of activation. As a remedy of the collapse instability, here we investigate a model of correlated NoN. We find that the collapse instability can be removed when hubs provide the majority of interconnections and interconnections are convergent between hubs. Thus, our study identifies a stable structure of correlated NoN against catastrophic failures. Our result further suggests a plausible way ...


Lab Manual Design With Engineering Learning Style And Flipped Learning Model In Computer Engineering Technology Education, Yu Wang, Sunghoon Jang Jan 2018

Lab Manual Design With Engineering Learning Style And Flipped Learning Model In Computer Engineering Technology Education, Yu Wang, Sunghoon Jang

Publications and Research

We have designed a lab manual based on Felder-Silverman learning style model (FSLSM) and the flipped classroom model for engineering education. This lab manual is developed for early junior year course of “Microcomputer Systems Technology” and emphasizes student-centered active learning experiences with more practical exercises and open-ended questions. Instead of taking traditional assembly language to study computer architecture, we are looking for a different approach to teach students to learn the assembly language by embedding an inline assembly language module into a C program. Our lab guide consists of online videos and practical exercises on various platforms including Microsoft Windows ...
