Mechanical and Systems Engineering Ph.D. Policies and Procedures
General Information
The Mechanical and Systems Engineering Ph.D. program is an interdisciplinary Ph.D. program with specialization tracks in Mechanical Engineering (ME) and Industrial and Systems Engineering (ISE). The Mechanical and Systems Engineering Ph.D. program prepares students for advanced engineering work in industry, government, or academia.
Program Tracks
- The ME track includes academic and research specialties in the areas of biomedical engineering, CAD/CAM, machine and automotive design, energy, manufacturing, materials and deformable solid body mechanics, robotics and rigid body mechanics, and thermo-fluid systems.
- The ISE track includes specialization areas in manufacturing systems, information systems, artificial intelligence, systems simulation, process planning, distribution systems, genetic algorithms, data mining, and location science, supply chain design, human factors, and reliability.
An interdisciplinary component, for which graduate coursework is taken outside the program track, is a general program requirement. In addition to general program requirements, specific track requirements must also be satisfied. Students must pass qualifying and comprehensive exams, as well as a successfully defend a doctoral dissertation. A minimum of 30 semester hours of dissertation and 30 semester hours of approved graduate coursework are required. A plan of study is approved by the student's dissertation advisory committee, the specialization track coordinator, and the chair of the program steering committee.
General Admission Information
The basic requirement for admission is a Master of Science degree in engineering or a related field, i.e., chemistry, physics, or applied mathematics. However, direct admission to the program may be possible if special circumstances are met and granted. Applicants holding degrees in closely related fields or from non-accredited engineering institutions may be required to compensate for deficiencies with additional coursework. The Graduate Record Exam (GRE) general test is required. The required test scores for the GRE are: 161 for Quantitative and 153 for Verbal. *NOTE: The GRE requirement can be waived by recommendation of your potential advisor. Three letters of recommendation are required from persons who can attest to the applicant's academic and research aptitude. 帝王会所鈥檚 Graduate College has additional requirements, which are the responsibility of the student to meet. Admission to the program is restricted to students with educational plans falling in one of the two specialty areas.
General Requirements
A maximum of eight (8) semester hours of graduate coursework, completed at another university, will be considered for credit towards degree completion. Such a request must be made in writing to the Russ College of Engineering and Technology, and will require approval by the Steering Committee and the student's dissertation advisory committee. Transfer credit MUST meet the University requirements for transfer at the graduate level. Graduate courses that were used to satisfy the requirements for another degree are not eligible for transfer. University residency requirements must be met as stated in the 帝王会所 Graduate Catalog. More than 8 semester hours will only be considered in exceptional situations.
A Plan of Study is developed on an individual basis with the student's advisor and dissertation advisory committee. Each Plan of Study must include the capstone synthesis course. In addition, students must include courses appropriate to the selected specialization track. A minimum of 12 credit hours of course work must be at the 6000 level or above, of which at least 3 credit hours must be at the 7000 level or above. All Plans of Study must include at least 60 credit hours, including at least 40 credit hours for the dissertation and 20 credit hours of course work above the M.S. degree (excluding ET6020). The plan must be approved by the student's advisor, dissertation committee, and the graduate chairman of either the ME or ISE department, depending on the track selected.
Students must pass the qualifying examination before earning 12 credit hours of course work applicable toward the Ph.D. degree, and a comprehensive examination no later than the end of four semesters of course work. Exceptions to the prescribed timeline may be considered on a case-by-case basis under extenuating circumstances only. The qualifying examinations encompass basic knowledge in mathematics, physics, and engineering subjects complimentary to the specialization track of study chosen by the student. The topics covered by the qualifying exam are at the advanced undergraduate and beginning graduate level and they determine the student's capability for advanced course work in engineering. The comprehensive examination measures the student's knowledge and integration of subject matter necessary for the successful completion of the dissertation. The student鈥檚 dissertation committee determines the format and content of the comprehensive exam.
Inquiries for admission into the program or requests for further information should be addressed to the graduate chairman of ME or ISE. University policies and general information regarding graduate studies are discussed in the of 帝王会所.
It is the responsibility of the Ph.D. candidate to ensure that these policies and procedures and those of the university are met.
Program Administration
Administration of the Mechanical and Systems Engineering Ph.D. Program is delegated to the Associate Dean for Research, Graduate Studies, and Planning (RGSP) of the Russ College of Engineering and Technology. The graduate chairmen of the ME and ISE departments assist the Associate Dean of RGSP in administering the program. Final authority rests with the Dean of the Russ College of Engineering and Technology.
Steering Committee and Specialization Track Coordinators
The Steering Committee (SC) is composed of the graduate chairmen of the ME and ISE departments. The Associate Dean of RGSP, who is responsible directly to the Dean of the Russ College, chairs the Steering Committee. Functions of the Steering Committee are:
- Set the direction for the program and establish program policies
- Evaluate and recommend applicants for admission
- Approve the dissertation advisory committees and Plans of Study of individual students
- Ensure that quality and integrity are maintained
- Assist the Associate Dean of RGSP and the dissertation advisory committee in administering qualifying and comprehensive examinations.
The duties of the ME and ISE chairmen are to develop guidelines for selecting courses for the track, approve programs of study, approve changes in programs of study, assist in administering qualifying and comprehensive exams, serve as initial advisors of new students who do not have a dissertation advisor, and help the Associate Dean of RGSP develop recruiting and promotional materials for the MSE Ph.D. program. The Associate Dean of RGSP consults with the Steering Committee in cases of exceptions to the Ph.D. program policies and guidelines.
Dissertation Advisory Committee
Each student must select a dissertation advisor no later than at the completion of the second semester after the initiation of the MSE Ph.D. program. The student's dissertation advisor must have research experience in the area that the student has selected to specialize. The dissertation advisor must be a member of the graduate faculty in the Russ College. The respective graduate chairman will advise students until they have selected a dissertation advisor.
The student's dissertation advisory committee, chaired by the student's dissertation advisor, consists of at least three graduate faculty members (including the dissertation advisor) from within the College and two external committee members. The Associate Dean for RGSP approves the external representatives based on recommendations from the student鈥檚 dissertation advisor. Each external representative must be a member of the graduate faculty of his or her college, or hold Associate Graduate Faculty status in the Russ College if the external representative is from an institution external to 帝王会所.
The dissertation advisory committee must have: (i) at least one member from each major department of study that the student has selected; and (ii) at least two members with previous experience in directing Ph.D. dissertations. A student's dissertation advisory committee should be formed and approved by the Russ College before the student completes three semesters of course work applicable toward the degree. When the dissertation committee is proposed, a recommendation should also be made regarding the external representatives. The external representatives must be approved before the student presents the research proposal to his/her dissertation committee. The graduate chairmen and the Associate Dean for RGSP approve all dissertation advisory committees and changes in the committee, as justified.
The student and the dissertation advisor establish the student鈥檚 Plan of Study under guidelines provided by the policies and procedures in this document. In addition to the periodic review of the Plan of Study by the respective program graduate chairmen, all members of the dissertation advisory committee (except for the external representatives) and the respective graduate chairman must formally approve the Plan of Study by reviewing and signing at least by the time of completion of the Comprehensive Examination. The Associate Dean of RGSP will give final approval of the Plan of Study by signing, if the Plan of Study adheres to the policies and guidelines of the Mechanical and Systems Engineering Ph.D. Program. In cases of exceptions to the guidelines or other special circumstances, the Associate Dean of RGSP will ask the Steering Committee to evaluate the Plan of Study and decide if exceptions are warranted. Changes in a Plan of Study must be submitted in a timely fashion and the approval process is the same as that for the original Plan.
The student's dissertation advisor oversees all aspects of the doctoral work and is directly responsible for quality control. The student and the dissertation advisor may periodically convene the dissertation advisory committee for the student to present progress reports and to seek advice and direction from the committee. If circumstances warrant, a student may petition for a change in the composition of the dissertation advisory committee. Changes to the advisory committee is executed using the same form and process as is used to initially form the committee.
Role of External Dissertation Committee Members
Two dissertation committee members must be from outside of the ME and ISE departments and one committee member must be from outside of the Russ College (such as from Physics, Chemistry, Math, Business, or Biology). In special cases it may be possible to have a college representative from another University. If an external representative is from a college that does not specify graduate faculty status, the faculty member must be engaged in teaching graduate courses, advising graduate students and publishing research results.
- Basic Requirements
- These members must be able and willing to assess the general "technical quality of the work" in comparison to the expectations for 帝王会所 graduate students and judge whether the work is "dissertation worthy". An external representative is not expected to have expertise in the technical content of the thesis, but to make sure that good research methods were used.
- These members must be able and willing to assess the general "quality of the document" in comparison to the expectations for 帝王会所 graduate students and judge whether the written document is of acceptable quality for a dissertation. The Introduction and Literature Search should be understandable to any educated reader, and the citations must meet an acceptable standard. An external representative is not expected to act as an editor, but rather as an assessor.
- Basic Expectations
- The members are expected to read the dissertation proposal document and participate in the proposal defense (approximately 3-5 hour time commitment).
- The members are expected to read the dissertation document and participate in the final defense (6 to 10 hour time commitment).
The members are expected to notify the College鈥檚 Associate Dean of RGSP of any concerns with the dissertation advisor or the overall process.
Admission
All prospective students must apply through the normal application procedure of 帝王会所. Application information and forms can be found on . The application procedures of 帝王会所 must be followed precisely.
The preference for admission is students who has earned a Master of Science degree in the desired engineering field (i.e. Mechanical or Industrial Engineering.) Admission may be possible for students who have earned a Masters degree in a related field, i.e., chemistry, physics, or applied mathematics. Applicants holding degrees in closely related fields or from non-accredited engineering institutions may be required to compensate for deficiencies with additional coursework. The Graduate Record Exam (GRE) general test is also required. Three letters of recommendation are required from persons who can attest to the applicant's academic and research aptitude. Admission to the program is restricted to those students whose educational plans fall within one of the two specialty areas.
The Steering Committee will have the final approval on admission in cases of exceptions to these guidelines, except as mentioned in the following paragraph. If the student applying for admission does not meet the basic requirements for pursuing graduate education in one of the specialization tracks, admission will be denied.
After following the admission process of 帝王会所, a student may be admitted directly to the MSE Ph.D. program by the Associate Dean of RGSP under the following conditions: 1. A graduate faculty member of the Russ College requests in writing that the student be admitted. 2. In this request, the faculty member justifies that the student has the academic qualifications and aptitude for research to successfully complete the MSE Ph.D. program. 3. The faculty member states that he/she will be the dissertation advisor of the student. The Associate Dean for RGSP will review the case and may ask for advice from others. If the prospective student appears to be academically qualified and has an aptitude for research, admission will be granted. The faculty member who made the request automatically becomes the student鈥檚 dissertation advisor.
Degree Requirements
At least 60 credit hours must be earned after admission to the program. Of this, at least 20 credit hours must be formal course work and at least 40 credit hours must be dissertation.
Course Work
A minimum of 20 credit hours of formal course work is required. At least 12 credit hours must be at the 6000 level or higher, of which at least 3 credit hours must be at the 7000 level or higher. Because the nature of this degree program is not a fixed curriculum but an integration of course work from at least two departments, it is necessary that the student develop an individualized Plan of Study that is appropriate for one of the two specialty areas: (1) Industrial and Systems Engineering or (2) Mechanical Engineering. The Plan of Study must include at least six credit hours of doctoral coursework outside the major track discipline. Students in both specialty tracks shall take the "capstone" synthesis course (ET 7990) after completion of a majority of the Ph.D. courses.
Students are required to take the 1-credit hour ET 6020 Technical Writing Seminar. Students who satisfied this requirement while earning an M.S at 帝王会所 are not required to retake this course during the doctoral program.
Courses taken prior to admission into the Ph.D. program can satisfy the requirements of credit hours for the major areas and the core courses. However, credit cannot be given for courses used to satisfy prior degree requirements.
Academic Credit for Course Work at Other Universities
A maximum of 8 semester credit hours of graduate coursework, completed at another university, will be considered for credit towards degree completion. Such a request must be made in writing to the Russ College of Engineering and Technology, and will require approval by the Steering Committee and the student's dissertation advisory committee. Graduate courses that were used to satisfy the requirements for another degree are not eligible for transfer. University residency requirements must be met as stated in the 帝王会所 . More than 8 credit hours will be considered only in exceptional situations.
Approval and Modification of Plan of Study
A preliminary Plan of Study shall be on file in the Dean鈥檚 office no later than the end of the first semester of entry into the MSE Ph.D. program. A final Plan of Study must be on file in the Dean's office by the completion of the comprehensive examination. The Plan-of-Study approved at the comprehensive examination must be signed by the student's dissertation advisory committee (with the exception of the external representatives), the track coordinator, and the Associate Dean for RGSP.
After approval, changes can be made, but the student's dissertation advisory committee, the track coordinator, and the Associate Dean for RGSP must approve the changes. The Plan of Study is to be updated, reviewed, and approved by the dissertation advisory committee at the completion of the comprehensive examination. The dissertation advisory committee may require that additional course work be added to the program of study if the comprehensive exam reveals weaknesses that may preclude the student from successfully completing his/her dissertation research. The updated and approved Plan of Study is to be submitted to the Dean's office, along with the results of the comprehensive examination.
If a student needs to take remedial courses for any reason, these courses must be included in the Plan of Study and so identified as not applicable toward degree requirements.
Academic Standards
A student must maintain a 3.0/4.0 grade point average to remain in the program. Students failing to maintain a 3.0/4.0 average may petition the Associate Dean of RGSP to remain in the program for one additional semester, during which the student's average must be corrected to at least 3.0/4.0. Only one such petition is allowed during the entire degree program.
No more than six credit hours below B (3.0) and no credit hours of C+ (2.33) or below may be counted toward the MSE Ph.D. More than 6 credit hours less than B- (2.66) will automatically drop the student from the program.
As part of the MSE Ph.D. degree program, a student will be registering for research and dissertation credits (ET 8940, ET 8950 and ISE6940). The student is required to meet with his/her advisor at the beginning of every semester and set up clear goals, objectives, associated tasks and expected deliverables to meet the requirements of ET 8940, ET 8950 and ISE6940. If the student does not maintain his/her research progress as discussed and agreed upon with the advisor, the department with the advisor will evaluate the renewal of the contract as per initial offer letter and cancellation of course registration (as per 帝王会所 university鈥檚 policy: ).
Qualifying Examination
The student must demonstrate mastery of the necessary fundamentals to pursue the Ph.D. degree by taking and passing the Ph.D. qualifying examination. The student must pass the qualifying exam in no more than two attempts. This examination will be offered twice a year (December and May or June). The first exam attempt must be taken prior to earning 12 credit hours of formal course work applicable toward the degree. If the student fails to do so, it will be counted as a "Fail of the Qualifying Examination". If for some exceptional reason a student fails to take the qualifying examination before earning 12 credit hours, he/she must take it at the next offering. In cases where remedial courses are required, the student will petition the chair of the Steering Committee requesting a delay in taking the exam and listing the remedial courses needed. Remedial coursework will not be counted toward the 20 credit hours required for the Ph.D. and, hence, will not count toward the 12 credit hours mentioned above. The student's advisor must endorse the petition.
The subject areas of this examination include those that are deemed necessary to pursue study at the advanced graduate level in preparation for performing research in one of the two specialty areas. The exam covers topics from the student鈥檚 specialty track. Both parts of the qualifying examination test basic knowledge at the advanced undergraduate and beginning graduate level.
The student shall also select one of the following specialty areas for examination:
- Industrial and Systems Engineering (See Appendix B for details.)
- Mechanical Engineering (See Appendix C for details.)
The results will be evaluated by the faculty who administer the exam in regards to the following: (i) a decision on pass/fail, (ii) recommendations for remedial course work, and (iii) a recommendation for a second (final) attempt. Because the results of this exam will be used to formulate or modify the student's Plan of Study, it is strongly recommended that the student take the qualifying examination as early as possible.
Comprehensive Examination
Following the completion of the majority of the course work as determined by an approved Plan of Study, but no later than four semesters into the MSE Ph.D. program, the student is required to pass a comprehensive examination. This exam must be passed in no more than two attempts. This examination will test the student's knowledge of the advanced level (Ph.D.) course work and his/her ability to integrate knowledge from courses for independent research.
The student鈥檚 dissertation advisory committee will decide the format of the examination in accordance with the respective department guidelines. (Typically, the comprehensive examination is a written examination followed shortly by an oral examination.) The examination is prepared and administered by the student's dissertation advisory committee. The student must consult with the dissertation advisory committee to schedule the exam. At the conclusion of the comprehensive examination, the student鈥檚 Plan of Study is reviewed. If the dissertation advisory committee detects a weakness in the student鈥檚 ability, the committee can add additional course work to the student鈥檚 program of study. An updated and approved Plan of Study is submitted to the Dean's office, along with the results of the comprehensive examination, by the student鈥檚 dissertation advisor.
Review of Research Proposal
Within six months of the successful completion of the comprehensive examination, the student must deliver an oral presentation of his/her proposal for dissertation research. A written version of the research proposal must be submitted to the dissertation advisory committee for review at least 14 calendar days before the oral review takes place.
The oral presentation is intended to evaluate the student's plan and ability to carry out his/her proposed dissertation research. The student should be prepared to answer questions regarding his/her research proposal, his/her major area of specialization, and general background. The dissertation committee and the track coordinator must approve the proposal. The student鈥檚 dissertation advisor is responsible for seeing that the 鈥淩esearch Proposal Approval鈥 form is submitted to the Office of the Associate Dean for RGSP.
Admission to Candidacy
Students are admitted to candidacy for the Ph.D. degree after:
- Passing the qualifying exam
- Satisfactorily completing the Comprehensive Examination
- Approval of research proposal
- Filing results of comprehensive exam and research proposal approval form in the Office of the Associate Dean of RGSP.
A student is not permitted to schedule the oral defense of the dissertation until all requirements for admission to candidacy have been met.
Dissertation
Students must adhere to all university dissertation guidelines with regard to format, submission procedures and deadlines. The thesis and dissertation submission form, the oral defense forms, and the deadlines for thesis oral defenses are also obtained through the Graduate College. The student is personally responsible for academic honesty, good literary style, proper grammar, and accurate spelling. Members of the dissertation advisory committee have the right to refuse to review the technical content of the dissertation if it does not meet accepted standards of English construction.
The completed dissertation, in "final" form, must be in the hands of each of the dissertation advisory committee members at least 14 calendar days prior to the oral defense.
- "Final" form in this context refers to dissertation quality; the dissertation advisory committee may still require changes in the content of the dissertation.
The oral defense of the research shall occur no sooner than nine months after the research proposal is presented and approved. The oral defense shall be scheduled and the Associate Dean for RGSP鈥檚 office notified at least 14 calendar days prior to the date of the oral defense. Approval of the oral defense by the advisory committee will not occur if the dissertation advisor, either of the external representatives, or any two of the advisory committee members do not approve.
Approval of the dissertation document will not occur if it fails to pass the required academic honesty screening or fails to receive unanimous approval of the committee.
Academic Honesty
The dissertation must pass academic honesty screening. The student must submit the dissertation to the Associate Dean for Research and Graduate Studies with a signed 鈥淪tatement of Originality鈥.
Time Limit
The maximum time allowed, from the official 帝王会所 program start date to completion of the doctorate degree is seven calendar years. The Associate Dean of RGSP has the authority to grant a one-semester extension with a written request from the student that is endorsed by the student鈥檚 major advisor. If all the requirements cannot be completed with a one-semester extension, the student can apply for readmission to the MSE Ph.D. Program. The MSE Ph.D. Steering Committee determines if readmission is justified and sets the terms and conditions for the student to complete the degree.
Normal start to finish time for a doctoral degree is five years or fewer. An annual review of student鈥檚 progress and program of study by the advisor is recommended to keep the student on track. If the student doesn鈥檛 finish within this time, a formal review of student鈥檚 progress at the end of each semester is required to guide the student to the completion of the degree. This review will also be used as basis for any dissertation or research credit registration approval by the Graduate Chair (Section 4.4).
Appendix B1
Guidelines for Qualifying Exams - Industrial and Systems Engineering Track
- Every candidate takes Probability and Statistics as their first topic.
- The student鈥檚 advisor selects the second topic in consultation with the student鈥檚 Ph.D. Committee and the student, considering the potential dissertation Ph.D. area and the student鈥檚 preparation (Operations Research, Manufacturing, Simulation, Production, Artificial Intelligence, Information Systems, Human Factors or any other relevant area).
- The Departmental Graduate Committee determines who will prepare and correct the exams.
- Total duration for both topics is 2 hours. The students will choose 2 questions out of 3 or 4 in each topic.
- The use of open notes and books is permitted during exams.
- The passing grade is 70 and higher out of 100 points.
- The student gets a second chance if he/she fails the exam in the first trial. The student can appeal to the Mechanical and Systems Engineering Ph.D. Steering Committee if he/she fails the exam in the second trial.
Appendix B2
Industrial and Systems Engineering Track: Guidelines for Comprehensive Examination
There are two options:
Option I
- Each engineering college member of the dissertation advisory committee will prepare 2 questions considering primarily the student鈥檚 Ph.D. and M.S. level course work. It is the student鈥檚 responsibility to provide an M.S. Plan of Study and Ph.D. Plan of Study to the committee members.
- The student will pick and answer three questions in two weeks. The emphasis is on testing the student鈥檚 knowledge on the advanced level courses and his/her ability to integrate knowledge from courses.
- The questions will be given on a Monday and the answers will be due the Friday of the following week. The committee will schedule the Oral Examination the week after. The Oral Examination is limited to 1.5 hrs. It will start with a presentation of the student鈥檚 answers and more discussions/questions will follow. This procedure is limited to 30 minutes per question.
- All members of the dissertation committee will vote at the end of the Oral Examination. The results will be satisfactory or unsatisfactory based on the majority vote. If unsatisfactory, the student will get a second chance with a new set of questions subject to the same timeline. A failure in the second trial may lead to recommendation for dismissal from the program by the dissertation advisory committee. The student can appeal to the Mechanical and Systems Engineering Ph.D. Steering Committee if he/she fails the exam in the second trial.
Option II
- The dissertation advisor will ask a single question and the student will have four weeks to answer the question.
- The committee will schedule the Oral Examination and all members of the dissertation committee will vote at the end of the Oral Examination.
- The results will be satisfactory or unsatisfactory based on the majority vote. If unsatisfactory, the student will get a second chance with a new topic subject to the same timeline. A failure in the second trial may lead to recommendation for dismissal from the program by the dissertation advisory committee. The student can appeal to the Mechanical and Systems Engineering Ph.D. Steering Committee if he/she fails the exam in the second trial.

C.2 Comprehensive Exam
The purpose of the comprehensive examination to evaluate the candidate鈥檚 ability to develop independent research. While the qualifying exam test written knowledge, the comprehensive examination allows for both demonstration of written and oral comprehension skills ranging from technical knowledge to identification of knowledge gaps in an area of research, formulation of research objectives, and the ability to create a work plan to meet the stated objectives.
Procedure
The comprehensive examination takes place before the dissertation proposal. The candidate鈥檚 primary advisor is responsible for formulating a suggested research question that is clearly not part of the candidate鈥檚 dissertation work. This suggested question must be approved by the candidate鈥檚 committee before presentation to the candidate. From this point forward, the candidate鈥檚 primary advisor is no longer a part of the process. The graduate chair will assign an additional member to the candidate鈥檚 committee to act at the 鈥淓xam Supervisor鈥 to complete the process. This includes scheduling a time for the committee (minus the primary advisor) to meet at the end of the two week examination period.
Once the research question has been given to the candidate, a two-week clock starts in which the candidate must identify research objective(s) and formulate a research 鈥減roposal鈥 including a work plant to address the question. This will take the form of both a written paper (less than 15 pages) and a presentation (less than 20 slides and 30 minutes.) The candidate must work with the graduate chair to ensure a viable room is available for the oral presentation three days after the delivery of the written proposal, which is due two weeks after question release. (The presentation should occur at seventeen days after the question release to the candidate.) The candidate must prepare not only for the presentation, but to defend the engineering principles behind the proposed work.
The candidate鈥檚 doctoral committee will make up the majority of the comprehensive committee. However, for the purpose of the comprehensive, the committee will consist of only engineering faculty or faculty from other departments that are competent in the science of the topic area. Note that the non-engineering committee member(s) will not be replaced, therefore there will likely be fewer members on the comprehensive committee.
Passing the Examination
This committee will evaluate the research proposal and convey its decision and comments to the candidate no later than the end of the next workday. If either the oral or the written proposal is considered unsatisfactory by any committee member, the candidate will have failed. If the candidate fails, a written explanation for the assessment of the failing performance will be provided to the candidate, advisor, and graduate chair of Mechanical Engineering. Each candidate has two chances to pass the exam. The second attempt will consist of a new topic, and will begin with two weeks to prepare an oral proposal.
Topic Selection
The topic selected should be in broadly the same field as the candidate鈥檚 research, but not directly related to the dissertation topic or a simple derivation thereof. The candidate is expected to know and apply terminology and fundamental principles common to the core mechanical engineering curriculum, and to stretch beyond his/her dissertation research. The candidate should not be expected to learn a large amount of specialized terminology or new subject matter specifically for the comprehensive exam. The comprehensive exam should draw from specialized knowledge already familiar to the candidate.
Selection of the comprehensive exam topic is a critical task that requires an investment of time and effort from the candidate鈥檚 primary advisor and his or her doctoral committee. All members should keep in mind the purpose of the comprehensive exam, the requirement that the research question NOT be aligned with the dissertation topic, and the interest of the department in maintaining a high quality graduate program. The department graduate chair will endeavor to rotate the Exam Supervisor role as much as possible. However, recognizing the potential for conflict with the candidate鈥檚 advisor, untenured faculty will not be appointed Exam Supervisor.
Preparing the Proposal
The candidate is responsible for all preparation for the comprehensive exam, including fundamental science and engineering principles underlying the topic. The candidate should review relevant literature to become familiar with the topic, identify a key question or knowledge gap, and then define a specific research objective and prepare a research proposal. The proposal should describe a research project that could be completed in 1鈥2 years.
A successful comprehensive exam solution has the following characteristics, most of which are common to any successful research proposal.
- It states a specific research objective.
- It explains the significance of the proposed research.
- References and summarizes only literature directly related to the proposed research
- It explains the science and engineering principles needed to perform the research
- It describes the methods and equipment used.
- Presents a clear work plan with explicit discussion of variables to be tested, a reasonable range of values examined with justifications. A 鈥渢est matrix鈥 may be appropriate.
- It includes methods for quantifying uncertainties.
- It explains how the results will be evaluated and how you will determine whether the objective has been met.
- It includes a schedule for completion of the project.
- It includes a rough budget and budget justification for the project.
- The project description is not more than 15 pages long, 12 point font, double-spaced, with numbered pages.
The statement of the research objective is the most critical part of the proposal. In the examples below, the unacceptable objectives are too vague. They do not clearly identify the independent and dependent variables investigated. There is no way to tell when the objective has been met and the project is finished.
Unacceptable:
The objective of this research is . . .
- 鈥淭o study catalytic converters.鈥
- 鈥淭o study how particle size affects catalytic converters.鈥
- 鈥淭o test metal-supported catalytic converters.鈥
- 鈥淭o model the operation of a catalytic converter.鈥
Acceptable:
The objective of this research is . . .
- 鈥淭o determine the relationship, if any, between active particle size and susceptibility of a metal-supported catalytic converter to poisoning by sulfur in the fuel.鈥
- 鈥淭o determine whether the choice of reactive element in the metal support affects the susceptibility of active metal particles in the catalytic converter to sintering.鈥
It is often appropriate to state the objective as a hypothesis.
鈥淲e hypothesize that the susceptibility of a metal-supported catalytic converter to poisoning by sulfur in the fuel is directly related to the surface area of the active particles, and, therefore, to the square of the average particle diameter.鈥
The proposal must convey the significance of the research. How does this work differ from what has gone before? How will fulfilling the research objective benefit specialists in the field? How will it benefit humankind? What is the next step when this project is finished?
For an experimental project, the work and plan and discussion of analysis of data should show a command of the fundamentals of experimental design and statistics. Even when the project focuses on modeling rather than experimentation, uncertainties are important. Consider the third of the acceptable example objectives. It would be important to quantify the sensitivity of the final model to changes in the thermal properties of the metal, the thermal properties of the gas, the flow rate of the gas, and the roughness of oxide the film.
The 帝王会所 Office of Research and Sponsored Programs (ORSP) has budget aid examples online. (Candidates should not contact ORSP staff directly for assistance in preparing a comprehensive exam solution.) Candidates should use an example for the National Science Foundation or the National Institutes of Health to prepare the budget. The committee will be satisfied with the right order-of-magnitude in each category (personnel, travel, materials and supplies, equipment, indirect costs, etc.).
The project description portion of the written proposal is not more than 15 pages long, 12 point font, double-spaced, with numbered pages. The 15 page limit does not include the cover page, abstract, budget, or list of references, but DOES include figures, tables, and appendices.
Acceptable Resources for Candidates to Use in Preparing Comprehensive Exam Solutions
The candidate may consult the university writing center or the 帝王会所 Program for Intensive English for assistance with language and grammar. No other candidates, staff, or faculty should review the candidate鈥檚 proposal before it is evaluated by the candidate鈥檚 committee. The candidate is encouraged to consult a style guide or technical writing guide. The candidate may read proposals written by other candidates, staff, or faculty. The candidate may use any literature or other resource in the public domain, including the peer-reviewed (preferred) and popular literature and web-based resources. Citations should contain sufficient information to allow the reader to find the original source material.
The candidate may draw on many resources, but must produce an original research proposal. Plagiarism will result in automatic failure. A candidate with any question about whether his/her work might constitute plagiarism should bring the source material and the proposal in progress to the Exam Supervisor for an opinion. International candidates in particular are cautioned that standards for plagiarism enforced in their home countries may be different from the prevalent standard in engineering and science research in the U.S. If the candidate鈥檚 committee assesses that the solution includes plagiarized material, the candidate will automatically fail the comprehensive exam, even if a 鈥減ass鈥 decision was previously rendered.
Comprehensive Exam Assessment Guidelines
A successful comprehensive exam solution has the following characteristics, most of which are common to any successful research proposal.
- It states a specific research objective.
- The objective is specific, not vague.
- The objective clearly identifies the independent and dependent variables (factors and responses).
- The objective reflects a higher motivation than simple data collection.
- It explains the significance of the proposed research.
- It is clear how this work differs from what has gone before.
- It is clear how meeting the objective will benefit specialists in the field and/or humankind.
- It references and summarizes only literature directly related to the proposed research and its significance.
- Discussion of prior work is organized to show relationship to the proposed work.
- Discussion of prior work shows relevant limitations or weaknesses as well as strengths.
- It provides a summary of the science and engineering principles used in the research
- It describes the methods and equipment to be used.
- Descriptions are understandable to engineers who are not experts in the particular techniques.
- Descriptions focus on the type, precision, and accuracy of the information obtained.
- It shows what variables will be tested, a reasonable range of values to be examined, and justification for the choices. A 鈥渢est matrix鈥 may or may not be appropriate.
- Independent variables (factors) are clearly identified.
- Dependent variables (responses) are clearly identified.
- The reasons for investigating each of the factors and responses are clearly described.
- It is clear why or how each of the factors is expected to influence the responses.
- It is clear that the factors and responses selected are sufficient to meet the objective.

- It is clear that the range investigated is reasonable given the time and resources allocated.
- It includes methods for quantifying uncertainties.
- Measurements or assumptions likely to make the largest contribution to the uncertainty are identified.
- Specific methods or techniques for quantifying uncertainties are identified. A broad statement such as 鈥渞eplicate measurements will be made to check accuracy鈥 is not sufficient.
