Computer-Simulation-Assisted Lean Manufacturing Training, Luoding Wang
Computer-Simulation-Assisted Lean Manufacturing Training, Luoding Wang
Theses and Dissertations
This thesis assesses the potential of using computer simulation to aid existing lean manufacturing training methods such as lecture and live simulation. An investigation of this possibility was carried out in conjunction with UMEP's Lean 101 class. In the study, two experimental computer simulation models demonstrating the push and pull production scenarios were constructed using ProModel software. Simulation models were equipped with a Visual Basic interface to aid trainees to manipulate the model via ActiveX. Constructed computer simulation was compared with live simulation to answer these research questions: 1. Was computer simulation able to teach additional lean concepts not covered …

In this paper, a distributed driver-in-the-Ioop and hardware-in-the-Ioop simulator is described with a driver on a motion simulator at the U.S. Army TARDEC Ground Vehicle Simulation Laboratory (GVSL). Realistic power system response is achieved by linking the driver in the GVSL with a full-sized hybrid electric power system located 2,450 miles away at the TARDEC Power and Energy Systems Integration Laboratory (P&E SIL), which is developed and maintained by Science Applications International Corporation (SAIC). The goal is to close the loop between the GVSL and P&E SIL over the Internet to provide a realistic driving experience in addition to realistic …
Algorithmic Beauty Of Buildings Methods For Procedural Building Generation, Jess Martin
Algorithmic Beauty Of Buildings Methods For Procedural Building Generation, Jess Martin
Computer Science Honors Theses
As virtual reality simulations, video games, and computer animated movies become more prevalent, the need arises to generate the content the three-dimensional models via an algorithm rather than crafting them by hand. Previous research in the area of procedural building generation has focused merely on the external appearance of commercial buildings. These methods are unsatisfactory for certain applications due to the lack of a walk-through feature. A new algorithm is proposed to generate residential units with realistic floor plans based partially on the architectural observations of Christopher Alexander. Results for the algorithm display real-time performance and a resemblance to real …
High-Throughput Inference Of Protein-Protein Interaction Sites From Unassigned Nmr Data By Analyzing Arrangements Induced By Quadratic Forms On 3-Manifolds, Ramgopal R. Mettu, Ryan H. Lilien, Bruce Randall Donald
High-Throughput Inference Of Protein-Protein Interaction Sites From Unassigned Nmr Data By Analyzing Arrangements Induced By Quadratic Forms On 3-Manifolds, Ramgopal R. Mettu, Ryan H. Lilien, Bruce Randall Donald
Computer Science Technical Reports
We cast the problem of identifying protein-protein interfaces, using only unassigned NMR spectra, into a geometric clustering problem. Identifying protein-protein interfaces is critical to understanding inter- and intra-cellular communication, and NMR allows the study of protein interaction in solution. However it is often the case that NMR studies of a protein complex are very time-consuming, mainly due to the bottleneck in assigning the chemical shifts, even if the apo structures of the constituent proteins are known. We study whether it is possible, in a high-throughput manner, to identify the interface region of a protein complex using only unassigned chemical shift …
A Sin Of Omission: Database Transactions, David Hansen
A Sin Of Omission: Database Transactions, David Hansen
Faculty Publications - Department of Electrical Engineering and Computer Science
Database courses are under increasing pressure to include new topics which inevitably leads to a decision about which topics are essential to the course and which can be omitted to make room for others. Recent surveys have indicated that many instructors are reducing or eliminating coverage of “transaction management” from their introductory database courses. As both an academic and a practitioner, I believe that this is a mistake. This paper discusses why the semantics of transaction management should be an integral topic in any introductory database management system course.

Bringing Up Robot: Fundamental Mechanisms For Creating A Self-Motivated, Self-Organizing Architecture, Doug Blank, Deepak Kumar, Lisa Meeden, James Marshall
Computer Science Faculty Research and Scholarship
In this paper we describe an intrinsic developmental algorithm designed to allow a mobile robot to incrementally progress through levels of increasingly-sophisticated behavior. We believe that the core ingredients for such a developmental algorithm are abstractions, anticipations, and self-motivations. We propose a multi-level, cascaded discovery and control architecture that includes the core ingredients. Toward this proposal we explore two novel models: a governor for automatically regulating the training of a neural network; and a path-planning neural network driven by patterns of “mental states” representing protogoals.
Deriving Private Information From Randomized Data, Zhengli Huang, Wenliang Du, Biao Chen
Deriving Private Information From Randomized Data, Zhengli Huang, Wenliang Du, Biao Chen
Electrical Engineering and Computer Science - All Scholarship
Randomization has emerged as a useful technique for data disguising in privacy-preserving data mining. Its privacy properties have been studied in a number of papers. Kargupta et al. challenged the randomization schemes, and they pointed out that randomization might not be able to preserve privacy. However, it is still unclear what factors cause such a security breach, how they affect the privacy preserving property of the randomization, and what kinds of data have higher risk of disclosing their private contents even though they are randomized. We believe that the key factor is the correlations among attributes. We propose two data …

This paper describes a comprehensive prototype of large-scale fault adaptive embedded software developed for the proposed Fermilab BTeV high energy physics experiment. Lightweight self-optimizing agents embedded within Level 1 of the prototype are responsible for proactive and reactive monitoring and mitigation based on specified layers of competence. The agents are self-protecting, detecting cascading failures using a distributed approach. Adaptive, reconfigurable, and mobile objects for reliability are designed to be self-configuring to adapt automatically to dynamically changing environments. These objects provide a self-healing layer with the ability to discover, diagnose, and react to discontinuities in real-time processing. A generic modeling environment …

Searching For High-Value Rare Events With Uncheatable Grid Computing, Wenliang Du, Michael T. Goodrich
Searching For High-Value Rare Events With Uncheatable Grid Computing, Wenliang Du, Michael T. Goodrich
Electrical Engineering and Computer Science - All Scholarship
High-value rare-event searching is arguably the most natural application of grid computing, where computational tasks are distributed to a large collection of clients (which comprise the computation grid) in such a way that clients are rewarded for performing tasks assigned to them. Although natural, rare-event searching presents significant challenges for a computation supervisor, who partitions and distributes the search space out to clients while contending with “lazy” clients, who don’t do all their tasks, and “hoarding ” clients, who don’t report rare events back to the supervisor. We provide schemes, based on a technique we call chaff injection, for efficiently …

A Random Rotation Perturbation Approach To Privacy Preserving Data Classification, Keke Chen, Ling Liu
A Random Rotation Perturbation Approach To Privacy Preserving Data Classification, Keke Chen, Ling Liu
Kno.e.sis Publications
This paper presents a random rotation perturbation approach for privacy preserving data classification. Concretely, we identify the importance of classification-specific information with respect to the loss of information factor, and present a random rotation perturbation framework for privacy preserving data classification. Our approach has two unique characteristics. First, we identify that many classification models utilize the geometric properties of datasets, which can be preserved by geometric rotation. We prove that the three types of classifiers will deliver the same performance over the rotation perturbed dataset as over the original dataset. Second, we propose a multi-column privacy model to address the …

Kno.e.sis Publications
Web services are the new paradigm for distributed computing. They have much to offer towards interoperability of applications and integration of large scale distributed systems. To make Web services accessible to users, service providers use Web service registries to publish them. Current infrastructure of registries requires replication of all Web service publications in all Universal Business Registries. Large growth in number of Web services as well as the growth in the number of registries would make this replication impractical. In addition, the current Web service discovery mechanism is inefficient, as it does not support discovery based on the capabilities of …

Web services have primarily been designed for providing inter-operability between business applications. Current technologies assume a large amount of human interaction, for integrating two applications. This is primarily due to the fact that business process integration requires understanding of data and functions of the involved entities. Semantic Web technologies, powered by description logic based languages like OWL[1], aim to add greater meaning to Web content, by annotating the data with ontologies. Ontologies provide a mechanism of providing shared conceptualizations of domains. This allows agents to get an understanding of users’ Web content and greatly reduces human interaction for meaningful Web …

Autism spectrum disorder (ASD) has become one of the most prevalent mental disorders over the last few years and its prevalence is still growing. The disorder is characterized by a wide variety of symptoms such as lack of social behavior, extreme withdrawal, and problems communicating. Because of the diversity in symptoms and the wide variety in severity for those, each autistic child has different needs and requires individualized therapy. This leads to long waiting lists for therapy.

Level Mapping Characterizations Of Selector-Generated Models For Logic Programs, Sibylle Schwarz, Pascal Hitzler
Computer Science and Engineering Faculty Publications
Assigning semantics to logic programs via selector generated models (Schwarz 2002/2003) extends several semantics, like the stable, the inflationary, and the stable generated semantics, to programs with arbitrary formulae in rule heads and bodies. We study this approach by means of a unifying framework for characterizing different logic programming semantics using level mappings (Hitzler and Wendt 200x, Hitzler 2003), thereby supporting the claim that this framework is very flexible and applicable to very diversely defined semantics.

On The Optimization Of Visualizations Of Complex Phenomena, Donald H. House, Althea D. Bair, Colin Ware
On The Optimization Of Visualizations Of Complex Phenomena, Donald H. House, Althea D. Bair, Colin Ware
Center for Coastal and Ocean Mapping
The problem of perceptually optimizing complex visualizations is a difficult one, involving perceptual as well as aesthetic issues. In our experience, controlled experiments are quite limited in their ability to uncover interrelationships among visualization parameters, and thus may not be the most useful way to develop rules-of-thumb or theory to guide the production of high-quality visualizations. In this paper, we propose a new experimental approach to optimizing visualization quality that integrates some of the strong points of controlled experiments with methods more suited to investigating complex highly-coupled phenomena. We use human-in-the-loop experiments to search through visualization parameter space, generating large …
Privacy-Preserving Top-N Recommendation On Horizontally Partitioned Data, Huseyin Polat, Wenliang Du
Privacy-Preserving Top-N Recommendation On Horizontally Partitioned Data, Huseyin Polat, Wenliang Du
Electrical Engineering and Computer Science - All Scholarship
Collaborative filtering techniques are widely used by many E-commerce sites for recommendation purposes. Such techniques help customers by suggesting products to purchase using other users’ preferences. Today’s top-recommendation schemes are based on market basket data, which shows whether a customer bought an item or not. Data collected for recommendation purposes might be split between different parties. To provide better referrals and increase mutual advantages, such parties might want to share data. Due to privacy concerns, however, they do not want to disclose data. This paper presents a scheme for binary ratings-based top-N recommendation on horizontally partitioned data, in which two …
Decision Fusion Rules In Multi-Hop Wireless Sensor Networks, Ying Lin, Biao Chen, Pramod K. Varshney
Decision Fusion Rules In Multi-Hop Wireless Sensor Networks, Ying Lin, Biao Chen, Pramod K. Varshney
Electrical Engineering and Computer Science - All Scholarship
We consider in this paper the decision fusion problem for a wireless sensor network (WSN) operating in a fading environment. In particular, we develop channel-aware decision fusion rules for a resource constrained WSN where decisions from local sensors may go through multi-hop transmission to reach a fusion center. Each relay node employs a binary relay scheme whereby the relay output is inferred from the channel impaired observation received from its source node. This estimated binary decision is subsequently transmitted to the next node until it reaches the fusion center. Under a flat fading channel model, we derive the optimum fusion …

Instantiations Of Shared Event Model In Grid-Based Collaboration, Minjun Wang, Geoffrey C. Fox, Marlon Pierce
Electrical Engineering and Computer Science - All Scholarship
The Internet is a global infrastructure that brings resources and people together. Diverse fields are prospering on it, such as Grid computing and collaboration. We demonstrate the Grid-based Collaboration idea by making three interface applications collaborative between computers over networks, using a common message broker as the underlying communication system. To achieve the global collaboration, we have brought together in the research a Grid-based Collaboration paradigm, a Shared Event model, different implementing structures, methodologies and technologies. We describe the applications’ event structures in messages coordinating the Grid-base collaboration. We further abstract the collaboration of the applications to be collaboration between …
