Bearing response test for the polymer matrix composite laminates: Optimization of displacement gage position

Narayana, Mohan Mittur (Wichita State University, 2008-05)

This thesis deals with composite joints with single shear tensile loading for a single piece specimen. The bearing response data from single shear test using a single piece specimen has been extensively used in the development ...
Best effort query answering for mediators with union views

Papri, Rowshon Jahan (Wichita State University, 2011-07)

Consider an SQL query that involves joins of several relations, optionally followed by selections and/or projections. It can be represented by a conjunctive datalog query Q without negation or arithmetic subgoals. We ...
Birdstrike analysis on leading edge of an aircraft wing using a smooth particle hydrodynamics bird model

Walvekar, Vinayak (Wichita State University, 2010-05)

Birdstrikes on aircraft pose a major threat to human life and there is a need to devolop structures which have high resistance towards these structures. According to the Federal Aviation Regulation (FAR 25.571) on ...
Blind carrier frequency offset estimation for multicarrier systems

Qasaymeh, Mahmoud Mohammad (Wichita State University, 2009-05)

A Multicarrier Communication (MCM) system such as an Orthogonal Frequency Division Multiplexing OFDM or Discrete Multi Tone (DMT) system has been shown to be an effective technique to combat multipath fading in wireless ...
Blind detection for two-hop relay network without direct link

Hodges, Shane Michael (Wichita State University, 2010-12)

In practice, channel coefficient information may not be available. Hence, a blind detection may be necessary. In addition, the direct link from a source to a destination may not be available. Therefore, information may ...
Blind detection with unique identification in two-way relay channels

Li, Lun (Wichita State University, 2011-12)

This thesis considers a two-way relay system whereby two nodes exchange information via a relay node. Amplify-and-forward (AF) is applied as a relaying strategy.The channel information is not available at both receivers. ...
Blind relay network with viterbi detection

Feng, Shuang (Wichita State University, 2010-12)

This thesis compared the performance of a blind relay communication system with that of a non-blind relay communication system. For a blind system, a differential space-time block code (DSTBC) or a blind Viterbi detection ...
Bottleneck shifting in production lines: Impact of variability, new detection method and control strategies

Tamilselvan, Prasannavenkatesh (Wichita State University, 2010-08)

One of the main causes for degrade in the performance of a production line is bottleneck machine. To improve system performance, bottleneck (BN) is one of the critical factors that need to be addressed. Most of the researchers ...
A bridge from stability to robust performance design of PID controllers in the frequency domain

Emami, Tooran (Wichita State University, 2009-12)

A graphical technique for finding proportional integral derivative (PID) controllers that stabilize a given single-input-single-output (SISO) linear time-invariant (LTI) system of any order system with time-delay has ...
Buckling, postbuckling and progressive failure analysis of hybrid composite shear webs using a continuum damage mechanics model

Herrero, Javier (Wichita State University, 2007-12)

This dissertation presents an innovative analysis methodology to enhance the design of composite structures by extending their work range into the postbuckling regime. This objective is accomplished by using the numerical ...
Buffer allocation in an unreliable homogeneous serial parallel production line

Venkataraju, Ram Prasaad (Wichita State University, 2010-12)

Buffers are inventory held in between machines to avoid stockout of parts. When a company has large buffer quantities between machines the inventory holding cost increases. Reducing the amount in a buffer increases the ...
Building a testbed for mini quadrotor unmanned aerial vehicle with protective shroud

Patel, Chirag Amrutbhai (2006-05)

Potential applications of small rotorcraft unmanned aerial vehicles (UAVs) range from military missions to exploration of the planet Mars (Patrick C. O’Brien, 2003). Tasks such as exploration of unknown territories, formation ...
A CAE-based study of reduction of crash aggresivity of pickup trucks

Krishnamurthy, Vikram (2005-12)

During the past few years, the disparity in the structural design of light trucks and vans (LTVs) and passenger cars and the number of fatalities involved in these vehicles has become a growing concern among automobile ...
Capacity of a modulo-sum simple relay network

Sagar, Youvaraj T. (Wichita State University, 2009-12)

This thesis proposes the capacity of a modulo-sum simple relay network. In previous work related to relay channels, capacity was characterized in the case where noise was transmitted to the relay, and the closed-form ...
Characterization of adhesives at room and elevated temperatures

Nedukanjirathingal, Santhosh Kumar (2006-07)
