New Gripping And Binding Device Greatly Improves Preparation Of Natural Clasts For Rfid Tracking, Samuel Slaven, Isaac Slaven, Alison M. Anders
New Gripping And Binding Device Greatly Improves Preparation Of Natural Clasts For Rfid Tracking, Samuel Slaven, Isaac Slaven, Alison M. Anders
Isaac Slaven
Radio frequency identification technology (RFID) has allowed for tracking of individual clasts implanted with passive integrated transponder (PIT) tags through sedimentary systems, providing recovery rates much higher than older sediment tagging methods such as painted or magnetic clasts. However, preparation of natural clasts for PIT tag implantation has been time-consuming and dangerous with rates of catastrophic failure of clasts of ∼66% or more. Moreover, failure rates increase as clast size decreases. The authors present an improved methodology that provides nearly 100% success rates and allows for drilling of clasts down to 23 mm along the intermediate diameter. The gripping and …
Modeling And Performance Analysis Of Distributed Systems With Collaboration Behaviour Diagrams, Toqeer A. Israr
Modeling And Performance Analysis Of Distributed Systems With Collaboration Behaviour Diagrams, Toqeer A. Israr
Toqeer A Israr
The use of distributed systems, involving multiple components, has become a common industry practice. However, modeling the behaviour of such systems is a challenge, especially when the behavior consists of several collaborations of different parties, each involving possibly several starting (input) and ending (output) events of the involved components. Furthermore, the global behavior should be described as a composition of several sub-behaviours, in the following called collaborations, and each collaboration may be further decomposed into several sub-collaborations. We assume that the performance of the elementary sub-collaborations is known, and that the performance of the global behavior should be determined from …

Libraries began to see service competition for the first time in the 1990s, due to the Internet and Google. The necessity of being more customer-focused became apparent, and this resulted in the creation of LibQUAL+, a tool developed to quantitatively measure the quality of customer service (Saunders, 2007). While LibQUAL+ serves as a first step toward increasing quality and value for patrons, library commitment to responding to survey results is essential.Although LibQUAL+ has been used by a wide range of libraries, this paper focuses on the use of LibQUAL+ by academic libraries, using two university libraries (Vanderbilt University and the …
Collaboration Between Private Sector And Academia: Arewe Compromising Our Engineering Programs?, Rigoberto Chinchilla
Collaboration Between Private Sector And Academia: Arewe Compromising Our Engineering Programs?, Rigoberto Chinchilla
Rigoberto Chinchilla
A central theme in the past ASEE Main Plenary in San Antonio, Texas, was the need to prepare our students for an “effective industrial practice.” Most panelists stressed the fact that “nowadays companies do not want to spend too much in training.” The direct implication at the end of the plenary was that academia was somehow “obligated” to supply engineers with the “right skills” for these companies. With the increased pressure in cost saving, according to the panelists in the plenary, the private sector has suggested that academia has to build a curriculum “ad-hoc” so they can hire “good engineers” …
Methodology For Evaluating Statistical Equivalence In Face Recognition Using Live Subjects With Dissimilar Skin Tones, Rigoberto Chinchilla
Methodology For Evaluating Statistical Equivalence In Face Recognition Using Live Subjects With Dissimilar Skin Tones, Rigoberto Chinchilla
Rigoberto Chinchilla
The general purpose of this study is to propose a methodology that can be employed in the application of facial recognition systems (FRS) to determine if a statistically significant difference exists in a facial recognition system’s ability to match two dissimilar skin tone populations to their enrolled images. A particular objective is to test the face recognition system’s ability to recognize dark or light skin tone subjects. In addition to the direct comparison of results from two different populations, this study uses a Box Behnken Design to examine four factors commonly effecting facial recognition systems. Four factors were tested, the …
Stochastic Performance Analysis Of Distributed Activities, Toqeer A. Israr
Stochastic Performance Analysis Of Distributed Activities, Toqeer A. Israr
Toqeer A Israr
This paper analyzes stochastic performance of a distributed global activity, composed of sub-activities sequenced serially, probabilistically, or concurrently. We provide general formulas with which we calculate the per-formance of a composite activity based on the performance of the constituent sub-activities and the control structure. To do this, we model each sub-activity as a Partially Ordered Specification (POS), where each sub-activity is character-ized by independent input events, dependent output events and the stochastic minimum delays between these events. This technique allows two or more sub-activities to be combined hierarchically. Proofs of correctness for these formu-las are given and a simple example …
Performance Modeling Of Distributed Collaboration Services With Independent Inputs/Outputs, Toqeer A. Israr, Gregor V. Bochmann
Performance Modeling Of Distributed Collaboration Services With Independent Inputs/Outputs, Toqeer A. Israr, Gregor V. Bochmann
Toqeer A Israr
This paper deals with modeling and performance analysis of dis-tributed applications, service compositions and workflow systems. From the functional perspective, the distributed application is modeled as an activity in-volving several roles, where behavior is defined in terms of compositions from several sub-activities using the standard sequencing operators found in UML Activity Diagrams. Each activity is characterized by a certain number of input and output events, and the performance of the activity is defined by the mini-mum delays that apply for a given output event in respect to each input event. We use a partial order to model these events, whose …

The Impact Of Three Interfaces For 360-Degree Video On Spatial Cognition, Wutthigrai Boonsuk, Stephen B. Gilbert, Jonathan W. Kelly
The Impact Of Three Interfaces For 360-Degree Video On Spatial Cognition, Wutthigrai Boonsuk, Stephen B. Gilbert, Jonathan W. Kelly
Wutthigrai Boonsuk
In this paper, we describe an experiment designed to evaluate the effectiveness of three interfaces for surveillance or remote control using live 360-degree video feeds from a person or vehicle in the field. Video feeds are simulated using a game engine. While locating targets within a 3D terrain using a 2D 360-degree interface, participants indicated perceived egocentric directions to targets and later placed targets on an overhead view of the terrain. Interfaces were compared based on target finding and map placement performance. Results suggest 1) nonseamless interfaces with visual boundaries facilitate spatial understanding, 2) correct perception of self-to-object relationships is …

Straight bladed fixed pitched vertical axis wind turbines (VAWTs) offer several potential advantages over the standard horizontal axis wind turbines which are now in common use worldwide. The purpose of this study was to determine the need for further research and develop on improved airfoil or blade characteristics for use on straight bladed fixed pitched VAWT. This need was demonstrated by the design and construction of an airfoil that was physically modeled and field tested. The test showed that asymmetric airfoils would enable SBVAWTs to self start.
Properties Of Wood Waste Stored For Energy Production, Isaac Slaven, Eva Haviarova, Daniel Cassens
Properties Of Wood Waste Stored For Energy Production, Isaac Slaven, Eva Haviarova, Daniel Cassens
Isaac Slaven
Storage of wood biomass is not a new concern, but our current focus on using wood for renewable energy has brought it back to researchers’ attention. Since much of the past research done on pile storage relates to paper pulp chips, most of it dates to the 1960s and 1970s. Fiber shortages during that period caused increased interest in higher pulp yields (Zoch, Springer, & Hajny 1976). Further interest in the use of whole trees came about from the energy crisis of the late 1970s. Recent efforts by the government to create a U.S. energy portfolio rich in renewable resources …

Automated Fixture Design For A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank
Wutthigrai Boonsuk
Rapid prototyping techniques for CNC machining have been developed in an effort to produce functional prototypes in appropriate materials. One of the major challenges for rapid machining is to develop an automatic fixturing system for securing the part during the machining process. The method proposed in this paper is the use of sacrificial fixturing, similar to the support structures in existing rapid processes like Stereolithography. During the machining process, sacrificial supports emerge incrementally and, at the end of the process, are the only entities connecting the part to the stock material. This paper presents methodologies for the design of sacrificial …

Algorithms To Automate Estimation Of Time Codes For Captioning Digital Media, Daniel P. Harvey Ii, Peter Ping Liu
Peter Ping Liu
Procedures were developed to partially automate the captioning process by estimating caption time codes using plain-text transcripts and audio recordings. Signal analysis is performed on the audio to measure pause location and duration, zero crossing rate (ZCR), and obtain frequency domain data. Algorithms were developed to match pauses in the audio to the ends of sentences in the transcript based on the observation that pause durations are greater at ends of sentences than within sentences. We have observed that ZCR peaks correspond to consonants in speech and that continuous wavelet transforms (CWT) work well for distinguishing between groups of consonants. …
Sources Of Wood & Wood Residues For Energy Production In Indiana, Isaac Slaven, Eva Haviarova, Klein Ileleji
Sources Of Wood & Wood Residues For Energy Production In Indiana, Isaac Slaven, Eva Haviarova, Klein Ileleji
Isaac Slaven
As energy prices rise and there is a push for energy to be produced from renewable resources, the contribution of Indiana’s corn and soybean industry often overshadows the impact that the State’s wood residues can have in response to these demands. Reports show that the wood products industry is the largest, by paid wages, of any agricultural industry in Indiana and employs 47,000 Indianans.1 In fact, Indiana has more than 4.5 million acres of forest land,2 compared to about 12.3 million acres of cropland.3 In addition to the millions of acres of forestland, Indiana has more than 1,600 wood products …

The focus of the paper is on the analysis of performance effects of different security solutions modeled as aspects in UML. Aspect oriented modeling (AOM) allows software designers to isolate and separately address solutions for crosscutting concerns, which are defined as distinct UML aspect models, then are composed with the primary UML model of the system under development. For performance analysis we use techniques developed previously in the PUMA project, which take as input UML models annotated with the standard UML Profile for Schedulability, Performance and Time (SPT), and transform them first into Core Scenario Model (CSM) and then into …

Evaluation of non-functional properties of a design (such as performance, dependability, security, etc.) can be enabled by design annotations specific to the property to be evaluated. Performance properties, for instance, can be annotated on UML designs by using the "UML Profile for Schedulability, Performance and Time (SPT)". However the communication between the design description in UML and the tools used for non-functional properties evaluation requires support, particularly for performance where there are many alternative performance analysis tools that might be applied. This paper describes a tool architecture called PUMA, which provides a unified interface between different kinds of design information …
