Chair's Message

I am proud to be working with faculty who continue to strive for excellence in academics/research, regional development and service. Since the fall semester 2006, departmental programs and activities are evolving from a strict focus on Engineering Technology to include a focus on Mechatronics Engineering and Technology. The faculty have been hard at work collecting and analyzing input from our constituents, including our students, and refining plans to improve the quality of our programs. At the same time, they continue to collaborate with existing industry partners and develop new ones to support students' learning through internships and co-ops, as well as student oriented research projects.

Our construction program, only two and a half years old, continues to grow significantly with an anticipated enrollment of

ore than 80 students this coming fall 2007 semester. The mfaculty and our construction industry partners have enthusiastically endorsed a MSET with a specialty in Construction Management. We expect to enroll students in this specialty as early as fall 2007.

The department faculty endorsed a plan in fall 2006 that allows the department to offer a Bachelor of Science, a Master of Science and a doctoral degree in Engineering within the next five years. This is consistent with the department's faculty-demonstrated capabilities as they relate to teaching and scholarly activities in their engineering fields. These plans are expected to enhance opportunities for competitive research funding, and increase the quality of our programs and services. Moreover, the plans are consistent with the mission and vision of the College of Engineering and the University. The Department faculty is hard at work pursuing researching innovative areas funded by a number of companies and agencies including TxDOT, NSF, NUCONSTEEL, and TXU.

Looking forward, two new tenure track faculty are expected to join the Department in fall 2007. Their expertise will enhance the Construction Engineering Technology and Mechanical Engineering Technology program respectively. As we say "Enjoy your career!" to our graduating students, we welcome our incoming students to their Department.

Experiential Engineering is the Best Teacher

Dr. Robert Hayes Undergraduate Advisor

When advising incoming students, I always encourage them to consider the cooperative education experience. Most students get caught up in the academic mode of going to class and surviving one day at a time and never avail themselves of the valuable experience of working with engineering professionals while they are completing their undergraduate degree. Leah Jamieson, Dean of Engineering at Purdue

University, and 2007 IEEE President, recommended "turning the curriculum inside out" at a recent keynote address at DesignCon 2007. She recommended a more experiential approach to engineering education that might include internships, entrepreneurship, service learning, and study abroad. Jamieson said it also involved "having students work on very realistic projects."

Jack Ganssle, a lecturer and consultant on embedded development, recently stated "...employers have been pinging me incessantly about the trouble they're having finding true embedded systems engineers, people who understand software, but who know about sensors, digitization issues, logic design and a smattering of analog electronics." He continues that such skills require "hands-on" experience. Many of the responses to Jack's article included testimonials of people who had benefited greatly from their school's cooperative education experience.

Engineering Technology at UNT has always emphasized practical, "hands-on" applications of the theory presented in the classroom. All undergraduate degrees require a capstone project course. More and more of these projects are sponsored by industry, which makes them very realistic. However, more is needed to prepare students at the baccalaureate level for what industry expects from them. Thus, I am back to where I began - students have the opportunity to get to the next level of experiential learning by combining undergraduate study and a cooperative education experience with a regional industry. The investment is an additional year of study but the return on investment is incalculable in terms of increased learning and marketability.

MBE Growth and Instrumentation

Sriteja Tarigopula

This thesis aims at applications of principles of engineering technology in the field of Molecular Beam Epitaxy (MBE), a versatile technique for growing epitaxial thin films of semiconductors and metals by impinging molecular beams of atoms onto a heated substrate under ultra-high vacuum (UHV) conditions.

The development and refinement of III-V MBE over the last two decades has transformed this UHV crystal growth technique into a near production-ready technology. A LabVIEW program was developed that will form the basis of a real-time control system that will transform MBE into a true-production technology. Growth conditions can be monitored in real-time with the help of the Reflection High Energy Electron Diffraction (RHEED) technique. The period of one RHEED oscillation corresponds exactly to the growth of one monolayer of atoms of the semiconductor material. The PCI-1409 frame grabber card supplied by National Instruments is used in conjection with the LabVIEW software to capture the RHEED images and capture the intensity of RHEED oscillations. The intensity values are written to a text file and plotted in the form of a graph. A Fast Fourier Transform of these oscillations gives the growth rate of the epiwafer being grown. All the data being captured by the LabVIEW program can be saved to file forming a growth pedigree for future use. Unattended automation can be achieved by designing a control system that monitors the growth in real-time and compares it with the data recorded from the LabVIEW program from the previous growth and adjusts the growth parameters automatically thereby growing accurate device structures.

Development of a Compact Deployable NERAC System for Detection of Damage

in Self-Sensing Composites, Dr. Vijay Vaidyanathan, Principal Investigator

Sponsored by Global Contour, Inc.

Intrinsically smart structural composites are materials which can perform functions such as sensing strain, stress damage or temperature. Smart structures are relevant and significant because of their relevance to phenomena such as hazard mitigation, structural health monitoring and energy saving. Cement-based materials that exhibit piezoresistivity with sufficient magnitude contain electrically conductive smart fibers that sense their own strain and damage.

Embedded devices, such as optical fibers, can monitor damage in structural material composites. The goal of this project is to develop a deployable Nodal Electrical Resistance Acquisition Circuitry (NERAC) hardware and post-processing analytical tools (software) to detect damage and strain in multifunctional materials such as carbon fiber composite structure and carbon fiber mixed cement concrete.

Testing and Analysis of Cold-Formed Steel Connections with Bolts in Oversize

Holes or Short slots without Washers Dr. Cheng Yu, Principal Investigator

Sponsored by the American Iron and Steel Institute

Bolted connections in cold-formed steel construction, without washers on oversize holes or short slots, may significantly expedite the building process and lower cost without loss of desired strength. However, current design specification does not include provisions for such connections, and washers are required in oversize holes or short slots.

This project aims to experimentally investigate three failure modes in bolted connections that the non-washer and oversize perforation configuration would affect directly. The three failure modes include shearing failure, bearing failure, and fracture failure in the next section of the connected sheet.

The two-year research project consists of two phases. In Phase I, shearing and bearing failures will be studied. In Phase 2, fracture failure will be investigated. The test matrix includes a full range of connection configurations covering steel thicknesses from 10 to 25 gauge, single and double shear, ASTM A307, A325, A354, A449, A490 bolts with diameters from 1/4 in. to 3/4 in., and low-ductility and high-ductility steel sheets. The research focuses on the application of A307 and A325 bolts with 1/2 in. diameter.

Evaluation of Dynamic and Static Electrical Characteristics for the DY8 &

YI8 Process Gallium diodes in Comparison to the D18 Process Boron

Diodes Swathi Dhoopi

A rectifier is an electrical device, comprising one of more semiconductor devices arranged for converting alternating current to direct current by blocking the negative or positive portion of the waveform. Teccor manufactures 15A rms to 25A rms rectifiers with voltages rated from 200V to 1000V. These rectifiers are packaged in an electrically-isolated TO-220 package and fabricated with a process called the D18-Process. After years of research, Teccor decided to fabricate rectifier chips with Gallium as p-type material to be added to silicon instead of the traditionally used Boron in their rectifiers. They created two different types of rectifiers with slight manufacturing differences using Gallium as the base referred to as DY8 & YI8 processes.

The purpose of this study was to evaluate dynamic and static electrical characteristics of rectifier chips fabricated with the DY8 process and the YI8 process and compare them with existing D18 process rectifiers. These new rectifiers were tested to compare their performance to meet or exceed requirements of lower forward voltages, leakage currents, reverse recovery time, and greater sustainability at higher temperatures compared to diodes manufactured using boron as base (D18 process diodes) for similar input variables.

No solid conclusions could be drawn as to the reliability of the anti-base rectifiers because of the short duration of the high-temperature AC blocking test. However, it is likely that the 150 DY8 rectifiers evaluated have a reliability problem since two of the 50 devices possessed a permanent change in current leakage that exceeded the 10A (internal) specification. Also, since the 150 YI8 showed no adverse change in current-leakage, it is a strong possibility that these devices would meet long term AC blocking testing.

Shear Resistance of Cold-Formed Steel Stud Walls with Wider Range of Options

in Steel Sheathing Dr. Cheng Yu, Principal Investigator

Sponsored by the American Iron And Steel Institute

Stud walls covered with steel sheet sheathing is a common practice in cold-formed steel construction to resist lateral loads such as those caused by wind and earthquake. However, the American Iron and Steel Institute (AISI) standard is limited to 0.018 in. (4:1 and 2:1 wall aspect ratio for both wind loads and seismic loads) or 0.027 in. (4:1 wall aspect ratio for both wind loads and seismic loads) thick steel sheet sheathing.

A test program is proposed to experimentally explore wider options in steel sheet sheathing to add more values of the optional thickness. The research will investigate the shear strength of standard 8 ft. by 4 ft. and 8 ft. by 2 ft. cold-formed steel stud walls with 0.030 in. or 0.033 in. steel sheet and 8 ft. by 4 ft. shear walls with 0.027 in. steel sheet sheathing. Fastener spacing to install steel sheet sheathing varies from 2 in. to 6 in.

The test program consists of two series of tests. The first will focus on the nominal shear strength of steel sheet walls for wind loads. The second series will address the nominal shear strength for seismic loads. The test procedure will be in accordance with ASTM E564-06 (2006) and ICC AC130 (2004). Results from the research are expected to expand the current AISI design standard for shear walls, thus benefiting the design and development of cold-formed steel structures.

Testing and analysis of Cold-Formed Steel Structures Dr. Cheng Yu

Sponsored by NUCONSTEEL

UNT and NUCONSTEEL have built a strong partnership in research. A new, cold-formed steel research center was developed. Faculty and NUCONSTEEL engineers work closely to analyze and develop innovative cold-formed steel structures such as shear walls with composite materials, new connections in roof trusses, and applications of high strength steel.

NIU and Ingersoll Cutting Tools Partner to Study "Green Manufacturing"

Dr. Nourredine Boubekri, Principal Investigator

More than 100 million gallons of metal working fluids are used in the United States each year, exposing about 1.2 million employees to potential health hazards. According to the Occupational Health and Safety Administration, such exposure may result in a variety of respiratory disorders, including asthma and hypersensitivity pneumonitis and also may cause conditions such as dermatitis and cancer.

This research, directed at Northern Illinois University by Professor Nourredine Boubekri before coming to UNT as Department Chair, could have implications in the metal-cutting industry worldwide. The Manufacturing Systems Research Group of NIU College of Engineering and Engineering Technology partnered with Ingersol Cutting Tools Corp to study the effectiveness of dry and semi-dry machining and reduce the use of metal working fluids.

Dr. Boubekri has been doing research in this area for some time and his work was funded in part by the Illinois Department of Natural Resources. He also formed a group of faculty and students from engineering, physics and mathematics to collaborate on ways to improve "green manufacturing" technology, particularly in the metal cutting industry.

The future looks bright in this area as the whole industry is searching for new tooling technologies and machining processes that are economical and environmentally friendly. The collaboration with Ingersoll Cutting Tools provides the necessary partnership to be able to lead this type of research.

Towards Design Provisions for Cold-Formed Steel Beams with Edge Stiffened

Perforations Horizontal Cracking in Concrete

Pavements Dr. Cheng Yu, Principal Investigator Dr. Seifollah Nasrazadani, Principal Investigator

Sponsored by the University of North Texas Sponsored by the Texas Department of Transportation Perforations on the web are required by cold-formed steel beams (generally C-sections) for piping, electric-wiring and plumbing. Traditional perforations on C-sections are flat bunched without any edge stiffener, and current North American Specifications (NAS) provide specific provisions for the traditional C-sections.

Spalling is a surface distress and rarely presents a structural distress. Spalling has more to do with the coarse aggregate type used in concrete. The only structural distress in continuously reinforced concrete pavement (CRCP) is punchout, a serious distress which needs to be repaired as soon as possible since un-repaired punchout can cause a safety hazard to the traveling public.

A new generation of C-section with edge stiffened perforations was developed and has been used in both commercial and residential constructions. The new product allows large sizes of perforations to be used without weakening the capacity of beams. However, research on the new generation C-sections is underdeveloped and public research results are not available.

TxDOT made changes in the mid-1980s which included the use of thicker concrete slabs, stabilized subbase and tied concrete shoulders. These changes have been effective. However, during the full-depth repair, there was a different form of punchout which the above changes did not appear to alleviate. Further evaluation revealed this distress is caused by horizontal cracks in concrete at a depth of close to that of longitudinal steel. This distress type was not acknowledged in the AASHO Road Test and has not been recognized by researchers and practitioners.

Pilot experimental investigation and finite element analyses of ABAQUS on typical C-sections with edge stiffened perforations were conducted. Results indicate Specification provides over-conservative predictions. Therefore new design provisions are required by industry to promote the new high-performance product. Research is to use a finite element model to analyze typical C-sections with edge stiffened perforations in the aspects of both elastic buckling and ultimate strength. New design provisions will be produced, and provisions based on the Effective Width method which is adopted by Specification for cold-formed steel members - so integration with existing methods becomes available.

This research study is to understand the mechanism of this type of distress, the factors responsible, and to develop guidelines that will mitigate this problem.

TxDOT uses the time consuming titration method for quantitative analysis of lime samples. This method is not an accurate test due to chemical interferences and sample preparation variances. In addition, the titration method consumes chemicals that are costly and add to the hazardous waste inventory. The purpose of this project is to implement Fourier Transform Infrared spectroscopy for lime testing.

Lime and its related materials absorb infrared rays and exhibit fingerprint spectra that are free of spectral interferences. An application of the Fourier Transform Infrared spectroscopy (FTIR) is proposed for rapid and accurate quantitative analysis of lime from three forms, including quick lime, hydrated lime, and slurry lime. FTIR is a safe method that requires minimal operator training and expertise.

Outstanding Alumni Nanoscale Characterization and Integration of Multifunctional Materials

and Devices 2007 Dr. Mike Kozak

Dr. Vijay Vaidyanathan, Co-Principal Investigator Beginning in 1984, recognition has been awarded to outstanding alumni of UNT. The following individuals have graduated from what is now the Engineering Technology Department and have been so recognized. Sponsored by NSF-MRI

The shrinking of devices and systems to the nanoscale limit is essential for the optoelectronics and biomedical engineering industry, and depends critically on the availability of novel materials and technology for achieving sub-wavelength coupling and operation. For practical application of nanotechnology in industry, it is becoming quite evident that increasingly multifunctional or "smart" materials will emerge as the new frontier within modern physical sciences as a whole. In this new era of nano-materials research, a truly pioneering activity that opens new fields of science and technology will require the merging of many traditionally separate, sometimes isolated, disciplines or sub-disciplines.

UNT Engineering Week 2007

Mr. Mark Pickens

Engineering Technology

This year's Annual National Engineer's Week was one of the premier events to take place at the College of Engineering, continuing to grow in size and participation each year. Engineer's Week was the product of hard work by representatives from student organizations, each department in the College, and the Dean's Office personnel. Each department organized an event which related to its area of study. Student Organizations, under direction of Mark Pickens, organized the annual Engineer's Week lunch and Career Fair.

Events included a Circuit Design Competition hosted by IEEE, an Open House hosted by Materials Science and Engineering, a paper airplane contest hosted by Dr. Nasrazadani, Engineering Technology, a XBOX 360 tournament hosted by Dr. Robert Akl, and a poker tournament hosted by Dr. Ryan Garlick.

Engineer's Week included a presentation by Landon Sproull, Chief Engineer, Denton Peterbilt Motors Co. Sponsored by the Dean's Office, Mr. Sproull's presentation illustrated the design process, from concept to market production, of their truck line and how it relates to each engineering discipline.

DC BEST 2006

The DCBEST Robotics Competition started with the KickOff Event at the UNT Research Park Facility on September 16, 2006. The KickOff was followed by the Mall Day Practice Day Event at the Golden Triangle Mall on October 21, 2006. Game Day Competition was held at Krum Middle School, Krum, Texas on October 28, 2006.

The theme for the 2006 robotic competition was "Laundry Quandry". The home-made robots had to pick up wet and dry laundry from certain clotheslines and put them in baskets. The same field consisted of four stations of clotheslines that were arranged around a gazebo which also had clotheslines in its center. The robots were designed to go over small hurdles to get to the high-scoring laundry sections. The game was more challenging than in years past because the robots could "steal" laundry from other stations.

The winners for the 2006 DCBEST competition were Era High School (first place) and Marcus High School (second place). The BEST, team oriented award went to Era High School followed by Lewisville High School and Ponder High School. Marcus High School went on to the State and National competition and earned the first place BEST National Championship.
