Convergence-Based Exploration Algorithm For Reinforcement Learning, Ala'Eddin Masadeh, Zhengdao Wang, Ahmed E. Kamal 2019 Iowa State University

Convergence-Based Exploration Algorithm For Reinforcement Learning, Ala'eddin Masadeh, Zhengdao Wang, Ahmed E. Kamal

Zhengdao Wang

Reinforcement learning (RL) can be defined as a technique for learning in an unknown environment. Through learning, two main modes select actions, exploration and exploitation. The exploration is to investigate unexplored actions. The exploitation is to exploit current best actions. Balancing between exploration and exploitation is a challenge for RL. In this work, an exploration algorithm for RL is designed. This algorithm introduces two parameters for balancing purpose, which are the action-value function convergence error, and the exploration time threshold. The first parameter evaluates actions and selects the best ones based on the convergent values of their action-value functions. The ...

Although autonomous and semi-autonomous ground vehicles are a relatively new reality, prototypes have been a subject of engineering research for decades, often utilizing an array of sensors and sensor fusion techniques. State of the art autonomous ground vehicle prototypes typically use a combination of LIDAR and other distance sensors (such as radar or sonar) as well as cameras and GPS ...


Sensor Intrusion Detection In Control Systems Using Estimation Theory, Jiayi Su 2019 Marquette University

Sensor Intrusion Detection In Control Systems Using Estimation Theory, Jiayi Su

Master's Theses (2009 -)

In this thesis, two different approaches to sensor intrusion detection are presented. In the first approach, an estimation algorithm using a bank of Kalman Filters is designed that is capable of estimating the intrusion signal when sensors are affected in control systems. The mathematical models of the control system will be estabilished and the system measurement will be shown and after that, various false signals, such as constant-type and ramp-type signal, will be selected as the intrusion signal to affect the system output mentioned above. The system measurement will be tested based on a bank of Kalman Filters. The probabilities ...


Investigation Of Electronic And Optical Properties Of 2-Dimensional Semiconductor Tin Selenide (Snse) Thin Films, Shakila Afrin 2019 Portland State University

Investigation Of Electronic And Optical Properties Of 2-Dimensional Semiconductor Tin Selenide (Snse) Thin Films, Shakila Afrin

Dissertations and Theses

Over the last 5 decades, the semiconductor industry has been well served by Si based technology due to its abundant availability, lower manufacturing cost, large wafer sizes and less complexity in fabrication. Over this period, electronic devices and integrated systems have been miniaturized by downscaling of the transistors. The miniaturization has been guided by the Moore's law where the numbers of transistors have doubled over every two years. However, the trend of transistor miniaturization is fast approaching its limit. Hence, alternate and innovative solutions are necessary to tackle this problem and this propels the research for finding novel materials ...

Wearable Bluetooth Sensors For Capturing Relational Variables And Temporal Variability In Relationships: A Construct Validation Study, James G. Matusik, Ralph Heidl, John R. Hollenbeck, Andrew Yu, Hun W. Lee, Michael D. Howe

Michael Howe

The advent of wearable sensor technologies has the potential to transform organizational research by offering the unprecedented opportunity to collect continuous, objective, highly granular data over extended time periods. Recent evidence has demonstrated the potential utility of Bluetooth-enabled sensors, specifically, in identifying emergent networks via colocation signals in highly controlled contexts with known distances and groups. Although there is proof of concept that wearable Bluetooth sensors may be able to contribute to organizational research in highly controlled contexts, to date there has been no explicit psychometric construct validation effort dedicated to these sensors in field settings. Thus, the two studies ...


Religious Devices: A Survey Of Technologies Of Worship., Hugh Davies 2019 RMIT

Religious Devices: A Survey Of Technologies Of Worship., Hugh Davies

communication +1

Responding to the unannounced spiritual mysticism surrounding contemporary technologies, a religiosity present in the prayer-like devotion of social media piety to the cultish intensity surrounding each iPhone launch, this paper aims to dispel presumptions of the spiritual in opposition to the technological by surveying a range of media devices specifically developed for religious purposes. More than connecting scholarship in technology, media and religion, this survey recommends a new arc in the cultural examination of technology. As curious media artefacts, religious devices are independently worthy of study but they also offer a material past to the so-called “religion of Silicon Valley ...

Development Of A Set Of Pre-Class Videos For Electromagnetic Theory, Benjamin McPheron, Josiah D. Kunz 2019 Anderson University - Indiana

Development Of A Set Of Pre-Class Videos For Electromagnetic Theory, Benjamin Mcpheron, Josiah D. Kunz

ASEE IL-IN Section Conference

One important aspect of experiential learning is allowing students time to reflect on new concepts before the application of the material. Most commonly, this is attempted by assigning readings from a textbook, but research suggests that few students complete these readings. This discouraging fact has prompted the use of other resources, such as videos, to supplement pre-class readings in order to introduce new material. Previous work has been completed by this author to produce pre-class videos for use in an introductory circuits course. This paper extends that work to the development of pre-class videos for a senior level electrical engineering ...

Efficient Methods For Robust Circuit Design And Performance Optimization For Carbon Nanotube Field Effect Transistors, Muhammad Ali 2019 Portland State University

Efficient Methods For Robust Circuit Design And Performance Optimization For Carbon Nanotube Field Effect Transistors, Muhammad Ali

Dissertations and Theses

Carbon nanotube field-effect transistors (CNFETs) are considered to be promising candidate beyond the conventional CMOSFET due to their higher current drive capability, ballistic transport, lesser power delay product and higher thermal stability. CNFETs show great potential to build digital systems on advanced technology nodes with big benefits in terms of power, performance and area (PPA). Hence, there is a great need to develop proven models and CAD tools for performance evaluation of CNFET-based circuits. CNFETs specific parameters, such as number of tubes, pitch (spacing between the tubes) and diameter of CNTs determine current driving capability, speed, power consumption and area ...

Lotfi ben Othmane

Organizations use fleet monitoring systems for e.g., vehicle tracking, driver behavior analysis, and efficient fleet management. Current systems are designed for commercial use and are of high cost. We present a prototype of a low-cost fleet monitoring system that could be used for non-commercial applications. The system is composed of a device, a service application, and a Web application. The device reads data such as speed and fuel from the internal network of the connected vehicle and the location of the vehicle and sends them to a remote service. The remote service processes and stores the data. The users ...

Details On Csa-Sbl: An Algorithm For Sparse Bayesian Learning Boosted By Partial Erroneous Support Knowledge, Mohammad Shekaramiz, Todd K. Moon, Jacob H. Gunther

Electrical and Computer Engineering Faculty Publications

This report provides details on CSA-SBL(VB) algorithm for the recovery of sparse signals with unknown clustering pattern. More specifically, we deal with the recovery of sparse signals with unknown clustering pattern in the case of having partial erroneous prior knowledge on the supports of the signal. In [1], we provided a modified sparse Bayesian learning model to incorporate prior knowledge and simultaneously learn the unknown clustering pattern. For this purpose, we added one more layer to support-aided sparse Bayesian learning algorithm (SA-SBL) that was proposed in [2]. This layer adds a prior on the shape parameters of Gamma distributions ...


Robustness Evaluation Of Computer-Aided Clinical Trials For Medical Devices, Kuk Jin Jang, Yash Vardhan Pant, Bo Zhang, James Weimer, Rahul Mangharam 2019 University of Pennsylvania

Robustness Evaluation Of Computer-Aided Clinical Trials For Medical Devices, Kuk Jin Jang, Yash Vardhan Pant, Bo Zhang, James Weimer, Rahul Mangharam

Real-Time and Embedded Systems Lab (mLAB)

Medical cyber-physical systems, such as the implantable cardioverter defibrillator (ICD), require evaluation of safety and efficacy in the context of a patient population in a clinical trial. Advances in computer modeling and simulation allow for generation of a simulated cohort or virtual cohort which mimics a patient population and can be used as a source of prior information. A major obstacle to acceptance of simulation results as a source of prior information is the lack of a framework for explicitly modeling sources of uncertainty in simulation results and quantifying the effect on trial outcomes.

In this work, we formulate the ...

Detection Of Injection Attacks In In-Vehicle Networks, Lotfi Ben Othmane, Lalitha Dhulipala, Moataz Abdelkhalek, Manimaran Govindarasu, Nicholas Multari

Lotfi ben Othmane

There have been several public demonstrations of attacks on connected vehicles showing the ability of an attacker to take control of a targeted vehicle by injecting messages into their Controller Area Network (CAN) bus. In this paper, using injected speed reading and Revolutions Per Minute (RPM) messages, we examined the ability of the Pearson correlation, the k-means clustering, and the Hidden Markov Model (HMM) techniques to differentiate ’no-attack’ and ’under-attack’ states of the given vehicle. We found that the Pearson correlation distinguishes the two states while the k-means fails to distinguish the two states and HMM can successfully detect attacks ...

Epics: A Framework For Enforcing Security Policies In Composite Web Services, Rohit Ranchal, Bharat Bhargava, Pelin Angin, Lotfi Ben Othmane

Lotfi ben Othmane

With advances in cloud computing and the emergence of service marketplaces, the popularity of composite services marks a paradigm shift from single-domain monolithic systems to cross-domain distributed services, which raises important privacy and security concerns. Access control becomes a challenge in such systems because authentication, authorization and data disclosure may take place across endpoints that are not known to clients. The clients lack options for specifying policies to control the sharing of their data and have to rely on service providers which provide limited selection of security and privacy preferences. This lack of awareness and loss of control over data ...
