Potential To Increase Indigenous Biodiesel Production To Help Meet 2020 Targets – An Eu Perspective With A Focus On Ireland, Fionnuala Murphy 2014 SelectedWorks

Potential To Increase Indigenous Biodiesel Production To Help Meet 2020 Targets – An Eu Perspective With A Focus On Ireland, Fionnuala Murphy

Fionnuala Murphy

The biofuels penetration rate target in Ireland for 2013 is 6% by volume. In 2012 the fuel blend reached 3%, with approximately 70 million litres of biodiesel and 56 million litres of ethanol blended with diesel and gasoline respectively. For January and February 2013, the blend rate had only reached 2.7%. The target of 10% by 2020 remains which equates to approximately 420 million litres. Achieving the biofuels target would require 345 ktoe by 2020 (14,400 TJ). Utilising the indigenous biofuels outlined in this paper leaves a shortfall of approximately 12,000 TJ or 350 million litres (achieving ...


Assessing Survivability Of The Beijing Subway System, Yan Li, Hyun Kim 2014 University of Wisconsin Milwaukee

Assessing Survivability Of The Beijing Subway System, Yan Li, Hyun Kim

International Journal of Geospatial and Environmental Research

The Beijing subway system, the third largest in the world, serves more than ten million passengers a day. As Beijing is the capital city of China and thus a booming urban center, its subway system has experienced rapid evolution from a local single line system to a complicated network. Due to its constantly increasing complexity, the system is both a critical asset for a local transit artery and a bridge between intercity transportation modes, increasing the issue of network survivability in the face of potential outages of network components. In this study, we provide a connectivity-based survivability measure with which ...

Detailed qualitative analysis of these case studies has highlighted some key issues in the area of customer service and identifies some opportunities for improvement.


A Set Union Based Formulation For Course Scheduling And Timetabling, Jesse Paul Bukenberger 2014 California Polytechnic State University

A Set Union Based Formulation For Course Scheduling And Timetabling, Jesse Paul Bukenberger

Master's Theses and Project Reports

The Course Timetabling Problem is a widely studied optimization problem where a number of sections are scheduled in concert with the assignment of students to sections in order to maximize the desirability of the resulting schedule for all stakeholders. This problem is commonly solved as a linear program with variables for each student or group of students with identical schedules. In this paper we explore an alternative formulation that aggregates binary student variables into integer variables denoting the number of students enrolled in a course. Our solution method assumes decomposition of the general schedule into time blocks, and applies a ...


The Feasibility Of Citywide Public Drt: Door-To-Door Bus Service In Tacoma, Nathan Pastor 2014 University of Puget Sound

The Feasibility Of Citywide Public Drt: Door-To-Door Bus Service In Tacoma, Nathan Pastor

Honors Program Theses

This paper examines the feasibility of operating Demand Responsive Transit (DRT) as the primary mode of mass transit in Tacoma, WA. With the promise of door-to-door service anywhere within a region, DRT has the potential to attract new discretionary mass transit riders while serving demand more efficiently than fixed-route systems. We present an algorithm for generating realistic datasets of riders based on employment and demographic data at the census tract level, which are fed through a simulated dynamic DRT system in Tacoma (TacDRT). The TacDRT service is considered feasible if it can serve the same volume of demand that the ...

Leveraging High Resolution Signalized Intersection Data To Characterize Discharge Headway Distributions And Saturation Flow Rate Reliability, Stephen M. Remias, Alexander M. Hainen, Gannon Grimmer, Alexander D. Davis, Christopher M. Day, Thomas M. Brennan Jr, James R. Sturdevant, Darcy M. Bullock

JTRP Other Publications and Reports

As highway systems become more congested, it becomes increasingly important to understand the reliability with which we can estimate important performance measures such as volume to capacity ratios, particularly as we move toward leveraging field infrastructure to obtain real-time performance measures. In 1947, Greenshields wrote a paper that characterized “green time consumed” by “car-in-line-number” that ultimately was called headway. Average headway is one of principles used by the highway capacity manual to estimate saturation flow rate at signalized intersections. However, the current analytical techniques calculate a deterministic value for saturation flow rate that does not consider the stochastic variation of ...


Active Sensing For Dynamic, Non-Holonomic, Robust Visual Servoing, Avik De, Karl S. Bayer, Daniel E. Koditschek 2014 University of Pennsylvania

Active Sensing For Dynamic, Non-Holonomic, Robust Visual Servoing, Avik De, Karl S. Bayer, Daniel E. Koditschek

Departmental Papers (ESE)

We consider the problem of visually servoing a legged vehicle with unicycle-like nonholonomic constraints subject to second-order fore-aft dynamics in its horizontal plane. We target applications to rugged environments characterized by complex terrain likely to perturb significantly the robot’s nominal dynamics. At the same time, it is crucial that the camera avoid “obstacle” poses where absolute localization would be compromised by even partial loss of landmark visibility. Hence, we seek a controller whose robustness against disturbances and obstacle avoidance capabilities can be assured by a strict global Lyapunov function. Since the nonholonomic constraints preclude smooth point stabilizability we introduce ...


Starch-Pectin Matrices For Encapsulation Of Ascorbic Acid, Yiwei Liu 2014 University of Nebraska - Lincoln

Starch-Pectin Matrices For Encapsulation Of Ascorbic Acid, Yiwei Liu

Dissertations & Theses in Food Science and Technology

Starch and pectin are two food-grade carbohydrates widely utilized in the food industry. Starch and pectin polymers have been investigated in encapsulating functional food ingredients and in pharmaceutical applications. Resistance to enzyme hydrolysis, differential solubilities, depending on the pH, and the ability to ‘protect’ unstable molecules are considered some of the beneficial properties of starch and pectin polymers, for encapsulation applications. Food ingredients could be delivered in a controlled manner to a specific target by encapsulating in micro-scale particles, i. e., microencapsulation. Two studies were conducted to investigate the ability of selected starch-pectin blends in microencapsulating ascorbic acid (vitamin C ...

Healthcare quality is determined based on the quality of the service provided to the patient during their visit. Apart from the traditional problem solving design and development tools used to improve healthcare quality, The National Academy of Engineering and the Institute of Medicine recommend systems engineering principle and systems engineering tools to be used in health care to improve the ...


Proportional Hazard Model Applications In Reliability, Alexandre Consul Mendes 2014 Northeastern University

Proportional Hazard Model Applications In Reliability, Alexandre Consul Mendes

Industrial Engineering Dissertations

This dissertation proposes two main methods as a modification of the semi-parametric Proportional Hazard Model (PHM) with innovative application for reliability testing. The first method developed uses a median of lifetime survival history for subjects with multiple occurrences to be modeled using the non-recurrent PHM method. The second method developed proposes censoring of influential observations, applying recurrent PHM theory. Both methods are validated using small electromechanical appliances with covariates identifying typical user performance as part of accelerated reliability testing.

The Median PHM method is developed to allow the treatment of time-dependent covariates and competing failure types, which is fairly often ...


Antiviral Resistance And Dynamic Treatment And Chemoprophylaxis Of Pandemic Influenza, Sandro Paz 2014 University of South Florida

Antiviral Resistance And Dynamic Treatment And Chemoprophylaxis Of Pandemic Influenza, Sandro Paz

Graduate School Theses and Dissertations

Public health data show the tremendous economic and societal impact of pandemic influenza in the past. Currently, the welfare of society is threatened by the lack of planning to ensure an adequate response to a pandemic. This preparation is difficult because the characteristics of the virus that would cause the pandemic are unknown, but primarily because the response requires tools to support decision-making based on scientific methods. The response to the next pandemic influenza will likely include extensive use of antiviral drugs, which will create an unprecedented selective pressure for the emergence of antiviral resistant strains. Nevertheless, the literature has ...


Statistical And Prognostic Modeling Of Clinical Outcomes With Complex Physiologic Data, Monica A. Puertas 2014 University of South Florida

Statistical And Prognostic Modeling Of Clinical Outcomes With Complex Physiologic Data, Monica A. Puertas

Graduate School Theses and Dissertations

Laboratory tests are a primary resource for diagnosing patient diseases. However, physicians often make decisions based on a single laboratory result and have a limited perspective of the role of commonly-measured parameters in enhancing the diagnostic process. By providing a dynamic patient profile, the diagnosis could be more accurate and timely, allowing physicians to anticipate changes in the recovery trajectory and intervene more effectively.

The assessment and monitoring of the circulatory system is essential for patients in intensive care units (ICU). One component of this system is the platelet count, which is used in assessing blood clotting. However, platelet counts ...


Developing A Pavement Management System Using Data Fusion Of Physical Features, Tarun Reddy Aleti 2014 Northeastern University

Developing A Pavement Management System Using Data Fusion Of Physical Features, Tarun Reddy Aleti

Civil Engineering Master's Theses

Pavement assessment is still plagued by the expensive and time-consuming distress data collection method. The VOTERS (Versatile Onboard Traffic Embedded Roaming Sensors) project has successfully transformed the way pavement inspections are performed, from mainly visual distresses identification to measurements of physical pavement condition features through the use of various sensing systems mounted on a vehicle. It allows network-wide determination and pavement condition ranking of our vast highway network. This thesis presents how these physical features can substitute for traditional distress assessment methods. Then these substitute features are used as the main inputs to a new kind of Pavement Management System ...


Investigating Present And Future Interactions Between Radio Frequency Identification, Additive Manufacturing And Supply Chain Management, Michael Nobuhiro Ochi 2014 California Polytechnic State University

Investigating Present And Future Interactions Between Radio Frequency Identification, Additive Manufacturing And Supply Chain Management, Michael Nobuhiro Ochi

Master's Theses and Project Reports

A screening experiment was paired with research observing the past, present and futures of additive manufacturing (a.k.a. rapid prototyping, 3D printing), radio frequency identification, and supply chain management. The experiment tested different properties of objects created with a desktop fused deposition modelling printer to observe if any single factors or interactions affected the read range of embedded passive UHF RFID inlay. The combination of material and infill percentage had a statistically significant effect on read range, however the analysis is weak since the data could not justify the normality assumption of ANOVA. Furthermore, the size of the effect ...


Track Separation In Stereophonic Music, Timothy D. Greer 2014 Washington University in St. Louis

Track Separation In Stereophonic Music, Timothy D. Greer

Undergraduate Research Symposium Posters & Abstracts

Many musicians improve by playing an active role in a band. Musicians also improve by learning how to transcribe and play songs on their own. If a musician could isolate an instrument in a song recording, he or she could either learn the instrument's part or omit that part from the recording in order to play with the remainder of the band. This project was aimed at isolating instruments to allow a musician to quickly improve through these learning techniques. The main goal was to take a prerecorded audio track – consisting of multiple instruments playing together – and separate it ...

Model-Iq: Uncertainty Propagation From Sensing To Modeling And Control In Buildings., Madhur Behl, Truong Nghiem, Rahul Mangharam

Real-Time and Embedded Systems Lab (mLAB)

A fundamental problem in the design of closed-loop Cyber-Physical Systems (CPS) is in accurately capturing the dynamics of the underlying physical system. To provide optimal control for such closed-loop systems, model-based controls require accurate physical plant models. It is hard to analytically establish (a) how data quality from sensors affects model accuracy, and consequently, (b) the effect of model accuracy on the operational cost of model-based controllers. We present the Model-IQ toolbox which, given a plant model and real input data, automatically evaluates the effect of this uncertainty propagation from sensor data to model accuracy to controller performance. We apply ...
