Performance Modeling Of Distributed Collaboration Services, Toqeer A. Israr, Gregor V. Bochmann
Performance Modeling Of Distributed Collaboration Services, Toqeer A. Israr, Gregor V. Bochmann
Toqeer A Israr
This paper deals with performance modeling of distributed applications, service compositions and workflow systems. From the functional perspective, the distributed application is modeled as a collaboration involving several roles, and its behavior is defined in terms of a composition from several sub-collaborations using the standard sequencing operators found in UML Activity Diagrams and similar formalisms. For the performance perspective, each collaboration is characterized by a certain number of independent input events and dependent output events, and the performance of the collaboration is defined by the minimum delays that apply for a given output event in respect to each input event …
Wind Power Technologies: A Need For Research And Development In Improving Vawt’S Airfoil Characteristics, Rigoberto Chinchilla, Samuel Guccione, Joseph Tillman
Wind Power Technologies: A Need For Research And Development In Improving Vawt’S Airfoil Characteristics, Rigoberto Chinchilla, Samuel Guccione, Joseph Tillman
Rigoberto Chinchilla
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.

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 …

Using biodiesel production as the centerpiece, the efforts of multiple academic programs were combined to achieve a common objective, thus illustrating the importance of cross-disciplinary collaboration. These programs include Chemical Technology, Sustainable Energy, Automotive Technology, HVAC, Biotechnology, and Agricultural Technology. By participating in the implementation of a closed-loop biodiesel supply chain, students learned the significance of communication and the interdependence of the myriad programs.

Automated Fixture Design For A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank
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
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. …

Faculty Research & Creative Activity
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 …

Faculty Research & Creative Activity
Researchers prefer on-demand routing protocols in mobile ad hoc networks where resources such as energy and bandwidth are constrained. In these protocols, a source discovers a route to a destination typically by flooding the entire or a part of the network with a route request (RREQ) message. The destination responds by sending a route reply (RREP) message to the source. The RREP travels hop by hop on the discovered route in the reverse direction or on another route to the source. Sometimes the RREP can not be sent to the intended next hop by an intermediate node due to node …
