Use Of Cycling Paths Along The Morogoro Brt Line, Ford Sanger

Independent Study Project (ISP) Collection

As the urban population continues to increase rapidly in Dar es Salaam it will become increasingly important to find sustainable means of urban transportation. With planned infrastructure improvements in the city to help alleviate traffic congestion, bicycles, which represent a largely underutilized form of urban transportation, have the potential to play a large role in the future of the city. Through background research, direct observations, community surveys, and interviews, both formal and informal, this study sought to understand the impact of the recent addition of bike lanes along the first phase of the Dar Bus Rapid Transit line. It was …

Cyber-Physical Systems: Complex System Governance As An Integrating Construct, Polinpapilinho F. Katina, Charles B. Keating, Adrian V. Gheorghe

Engineering Management & Systems Engineering Faculty Publications

This paper examines contributions of Complex System Governance (CSG) as an integrating construct for the emerging fields of critical cyber-physical systems (CPS). CPS is concerned with physical entities that are controlled by computational elements. The field is relatively new, emerging, and also somewhat fragmented in development. There are multiple agencies, entities, and activities being undertaken to address a nexus of emerging issues (e.g., cybersecurity) in critical infrastructures. However, the development of critical CPS, as a field, albeit with good intentions and efforts, appears to be largely ‘self-organizing.’ In response, we suggest CSG as an organizing construct capable of provided a …

Exploring A Toll Auction Mechanism Enabled By Vehicle-To-Infrastructure Technology, Andrew J. Collins, Erika Frydenlund, R. Michael Robinson, Mecit Cetin

VMASC Publications

High-occupancy toll (HOT) lanes—an increasingly popular solution for congested roadway networks—give drivers the option to access express lanes. The cost of entry often varies with demand, although no standard method of optimizing these price points exists. Using the principles of a Vickrey auction that incentivizes true-value bids, this paper proposes a tolling system that uses vehicle-to-infrastructure technology to optimize toll operator revenue with HOT lane usage. In the scenario, a roadway network consists of a HOT lane and a general-purpose lane, each with identical physical properties. Drivers can access the HOT lane at the start of the facility or at …

Framing The Question, "Who Governs The Internet?", Robert J. Domanski

Publications and Research

There remains a widespread perception among both the public and elements of academia that the Internet is “ungovernable”. However, this idea, as well as the notion that the Internet has become some type of cyber-libertarian utopia, is wholly inaccurate. Governments may certainly encounter tremendous difficulty in attempting to regulate the Internet, but numerous types of authority have nevertheless become pervasive. So who, then, governs the Internet? This book will contend that the Internet is, in fact, being governed, that it is being governed by specific and identifiable networks of policy actors, and that an argument can be made as to …

Public Works For Public Learning: A Case Study, Thalia Anagnos, Beckey Carroll, Shannon Weiss, David Heil

Faculty Publications

Large scale and small scale public works projects are important in the smooth operation of every community, yet a majority of the population has little awareness of how these projects work and what their functions are. Few non-engineers understand the engineering challenges of delivering clean water, disposing of our sewage, or changing a traditional intersection into a round-about, a project that seems quite simple on the surface. A consortium of public works engineers, science museums, faculty, and exhibit evaluators were awarded a grant by the National Science Foundation to build an outdoor museum next to a large suspension bridge. The …

Public Works Projects As Vehicles For Engineering Education And Outreach, Shannon Weiss, David Heil, Thalia Anagnos

Faculty Publications

America is built on small and large feats of public works engineering that, although often taken for granted, affect almost every aspect of our daily lives. So how can we celebrate these marvels of utilitarian infrastructure and use them to teach public audiences about the engineering principles, materials, and human innovations that make them possible? This case study will share how one project addressed these questions by leveraging informal learning strategies, multi-agency collaborations, and new media technologies to explain the history and engineering of one of the world’s most recognizable public work sites: the Golden Gate Bridge.

Technology & Society Faculty Publications

This report describes the municipal waste management systems used by local governments to manage solid waste in Suffolk County, Long Island, New York. There are ten Towns that serve as the primary planners for waste systems in Suffolk County. Many of the 33 villages in Suffolk County have established their own waste management programs and policies. All programs tend to follow the same general plan of the approaches used by their respective Towns, however. All programs provide some degree of recycling services, although the scope of the services varies tremendously.

A Systemic Approach To Next Generation Infrastructure Data Elicitation And Planning Using Serious Gaming Methods, Ersin Ancel

Engineering Management & Systems Engineering Theses & Dissertations

Infrastructure systems are vital to the functioning of our society and economy. However, these systems are increasingly complex and are more interdependent than ever, making them difficult to manage. In order to respond to increasing demand, environmental concerns, and natural and man-made threats, infrastructure systems have to adapt and transform. Traditional engineering design approaches and planning tools have proven to be inadequate when planning and managing these complex socio-technical system transitions. The design and implementation of next generation infrastructure systems require holistic methodologies, encompassing organizational and societal aspects in addition to technical factors. In order to do so, a serious …

The discussion includes (1) the need for sustainable risk management (2) the importance of time valuation in evaluating competing loss prevention and loss reduction alternatives, (3) the convergence of deterministic engineering economics, survivability analysis, and probabilistic analysis, and (4) hypothetical examples of the Delayed-Bang Approach and significance towards more sustainable risk management.

Evaluation Of Safety Impact Of Access Management In Urban Areas, Xuecai Xu

UNLV Theses, Dissertations, Professional Papers, and Capstones

The access provided by streets and highways to adjacent lands are managed by controlling the spacings between the access points including signals, driveways, and media openings on mid-block segments, and setting the limit on the corner clearances around intersections. There have been studies on evaluating the impact of access management techniques on safety and mobility in urban areas. Samples of mid-block segments and intersections can be collected from selected arterials. Because the mid-block segments or intersections in the same arterials share the same missing information, safety and mobility on them show unique features that should be taken into account when …

Cyber This, Cyber That...So What?, Eric D. Trias, Bryan Bell

Faculty Publications

This article endorses the idea that cyber operations may be conducted in all war-fighting domains: air, space, cyberspace, land, and sea. In addition, despite the immaturity of cyberspace operational doctrines, the doctrines from air and space remain relevant and applicable to the cyberspace domain. Cyber operations are just another set of tools in the commander's toolbox. Although cyber operations have distinct ways of achieving effects, from an Air Force perspective they are similar too the air and space operations that support air and space (and cyberspace) functions. Known and established cyber operations provide war fighters with viable options to kinetic …

Critical Infrastructure Rebuild Prioritization Using Simulation Optimization, Namsuk Cho

Theses and Dissertations

This thesis examines the importance of a critical infrastructure rebuild strategy following a terrorist attack or natural disaster such as Hurricane Katrina. Critical infrastructures are very complex and dependent systems in which their re-establishment is an essential part of the rebuilding process. A rebuild simulation model consisting of three layers (physical, information, and spatial) captures the dependency between the six critical infrastructures modeled. We employ a simulation optimization approach to evaluate rebuild prioritization combinations with a goal of minimizing the time needed to achieve an acceptable rebuild level. We use a simulated annealing heuristic as an optimization technique that works …

Quantifying Vulnerability To Critical Infrastructure, Barry Charles Ezell

Engineering Management & Systems Engineering Theses & Dissertations

Military and civilian leaders have the responsibility to protect our Nation's critical infrastructure, communities, and symbols of American power from terrorists, home and abroad, as well as from natural disasters. To this end, assessments are conducted to reduce vulnerability. The literature offers multiple definitions of vulnerability and measurement has not been adequately addressed. Thus, the purpose of this research has been to develop and deploy a systems-based model that quantifies vulnerability to critical infrastructure. This research defines critical infrastructure vulnerability as a measure of the susceptibility of critical infrastructure to threat scenarios. Vulnerability is a function of (1) threat scenario, …

An Analysis Of Multiple Layered Networks, Kevin T. Kennedy

Theses and Dissertations

Current infrastructure network models of single functionality do not typically account for the interdependent nature of infrastructure networks. Infrastructure networks are generally modeled individually, as an isolated network or with minimal recognition of interactions. This research develops a methodology to model the individual infrastructure network types while explicitly modeling their interconnected effects. The result is a formulation built with two sets of variables (the original set to model infrastructure characteristics and an additional set representing cuts of interdependent elements). This formulation is decomposed by variable type using Benders Partitioning and solved to optimality using a Benders Partitioning algorithm. Current infrastructure …

An Appraisal Of Electricity Supply In Nigeria And The Privatisation Option, E. I. K. Sule, C. M. Anyanwu

CBN Occasional Papers

Incessant electric power cuts in most parts of the country has become a normal feature of electricity supply throughout Nigeria. The power outages cause much inconvenience and economic losses to all and sundry. This study has shown that the most critical factor behind the incessant power failure is the problem of inadequate funding of the industry at a time it was forced to accommodate rapid expansion. Other factors include lack of autonomy, inefficiency, poor organization as well as lack of skilled manpower. The paper has examined these problems on the basis of which suggestions are made on how the worrisome …
