Operational tolerance allocation and machine assignment under process capability and product value constraints

Altarazi, Safwan A. (2005-05)

Process planning is an activity within the production process that translates design requirements into a detailed description of instructions for transforming a raw stock of material into a completed product. The instructions ...
Direction of arrival angle estimation schemes for wireless communication systems

Tayem, Nizar Abdel-Hafeeth Mohammad (2005-05)

In array signal processing, estimation of the direction of arrival angle (DOA) from multiple sources plays an important role in the array processing area, because both the base and mobile stations can employ multiple antenna ...
Analytical modeling of metallic honeycomb for energy absorption and validation with FEA

Jeyasingh, Vinoj Meshach Aaron (2005-05)

Honeycomb materials possess high energy absorption characteristics and are useful for the impact protection of structural members. Various honeycomb configurations are being developed for a variety of applications. Analytical ...
Finite element analysis of vertebral end-plate failure under high dynamic axial load and its relation to age

Kalyanrao, Thorbole Chandrashekhar (2005-07)

This research was aimed to develop the analytical model of functional spinal unit with the intent of understanding the contribution of Intervertebral disc condition on the failure mechanism of End-plates under high rate ...
Development of friction compensation control and application to fuel valve control systems

Feiz, Majid (2005-07)

This research involved the design of a position control system, based on a new method of observer-adaptive friction compensation, for a fuel valve that controls the flow of gas in large turbines. This fuel valve is ...
LDPC encoded pilots for iterative receiver improvement

Hassan, Khurrum (2005-12)

Turbo and low density parity check (LDPC) codes show performances approaching Shannon capacity. This thesis proposes a novel iterative channel estimation and LDPC decoding scheme where the pilot symbols are encoded and can ...
Optimal zonal protocol for containing rebroadcast in mobile ad-hoc networks

Malla, Deependra (2005-12)

With the proliferation of inexpensive and widely available wireless devices, the arena of mobile computing has been expanded dramatically in recent years. Mobile ad hoc networks have been envisioned as the future of wireless ...
Analysis of 3+2 point seat belt configuration and occupant responses in rollover crash of a pick-up truck

Marudhamuthu, Karthikeyan (2005-12)

This thesis studies the effectiveness of 3+2 Point Seat Belt system in making the car environment safer. The new and enhanced 3+2 Point Belt has conventional 3 Point Belt and an additional shoulder Belt conveyed from other ...
Energy absorption characteristics of stitched corrugated sandwich panels

Mariyanna, Vivek B. (2005-12)

The tailorability of composite sandwich structure with their strength- to- weight ratio interests in all field of crashworthiness application. An investigation of sandwich structure under static and high speed condition ...
Propeller performance measurement for low Reynolds number unmanned aerial vehicle applications

Merchant, Monal Pankaj (2005-12)

The recent increase in the development of UAV’s and MAV’s has created a strong demand for small propeller performance data. Propeller performance is critical to the success of these aircraft and guaranteed performance ...
Setup approval and self starting schemes for short production runs

Jadhav, Sameer A. (2005-12)

A number of approaches have been proposed for applying statistical process control in short production runs. However little has been done to provide a methodology to compare and select from various statistical process ...
Enhanced routing protocol for graceful degradation in wireless sensor networks during attacks

Radhakrishnan, Preetha (2005-12)

With the deployment of Sensor networks gaining some popularity, researchers are now focusing on solving the issues concerned with making sensor networks more feasible and viable. As Sensor networks have various constraints ...
Design and analysis of a composite beam for side impact protection of a sedan

Basavaraju, Divakara H. (2005-12)

Side Impact crashes can be generally dangerous because there is no room for large deformation to protect an occupant from the crash forces. The side impact collision is the second largest cause of death in United States ...
Comparison of structural damage and occupant injuries corresponding to a vehicle collision onto a pole versus a flat barrier

Hassan, Muhammad Aamir (2005-12)

Safety is of paramount importance to manufacturers of roadway vehicles. Although in the past few years much progress has been made in the field of passenger safety in cars, there is still a strong need for the design of a ...
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 ...
Development of a new boundary layer control technique for automotive wind tunnel testing

Farrell, Thomas Elmer (2005-12)
