Five-Year Program The college offers a combined B.S. + M.S. program in Mechanical Engineering designed to lead to a Bachelor of Science degree as well as a Master of Science degree in five years. Applicants for this program must have a high school GPA above 3.6, complete the Entry Level Writing Requirement before matriculation, and have sufficient mathematics preparation to enroll in calculus in their first quarter as freshmen. Eight units of technical electives will count in both programs, reducing the total number of units required for the MS degree.

Interested students who are entering their junior year should check with their academic advisor for information on eligibility and other details.

Admission In addition to the following requirements, all applicants must meet the general require- ments of the Riverside Division of the Aca- demic Senate and the UCR Graduate Council as set forth in this catalog under the Graduate Studies section.

Language Requirement All international students whose first language is not English must demonstrate proficien- cy in spoken English by securing at least a “conditional pass” score on the TAST or SPEAK test before they can be appointed as a TA. However, to be considered for subsequent TA appointments, they must secure a “clear pass” on the TAST or SPEAK. The fee associated with this test is paid by the department for the first attempt only. The TAST or SPEAK requirement is, however, waived for international students who are appointed as GSRs or are self-sup- ported throughout their studies at UCR.

The Department of Mechanical Engineering of- fers the M.S. degree in Mechanical Engineering.

Admission Applicants should have an undergraduate degree in engineering, physical sciences, or mathematics with a minimum overall GPA of 3.0 or equivalent (if GPA is not based on a 4.0 scale). All official transcripts and three letters of recommendation must be submitted for evaluation. Foreign students and permanent residents whose first language is not English must also submit an acceptable TOEFL test score prior to admittance; the minimum TOEFL exam score is 550 (paper-based) or 80 (inter- net- based).

The M.S. degree in Mechanical Engineering can be earned by either completing a thesis (Plan I), which reports a creative investigation of a defined problem, or passing a comprehensive examination (Plan II). A minimum of three quarters of residency is required. Students should enroll in 12 units each quarter unless the graduate advisor grants an exception.

Course work used to satisfy the student’s un- dergraduate degree requirements may not be applied toward the 36-unit M.S. requirement. Plan I (Thesis) Requires completion of a minimum of 36 units of upper-division and graduate-level approved course work and submission of an acceptable thesis. At least 24 of these units must be in graduate courses (200-series courses), a min- imum of twenty of these units being Mechan- ical Engineering graduate courses (ME 200 or higher, excluding ME 250, ME 290, ME 297, ME 298I, and ME 299). The student must take at least 3 units of seminar (ME 250) and at least 7 but no more than 11 units of directed or thesis research credits (ME 297 or ME 299). No more than 8 units of course work may be satisfied with directed studies (ME 290) or individual internship (ME 298I). Students must defend the thesis.

An acceptable M.S. thesis must be submitted. The M.S. thesis may be based on:

• 1. A research or advanced design project,

either analytical, computational or exper- imental;

• 2. An extensive report consisting of theo-

retical, computational or experimental contribution to mechanical engineering.

The student’s M.S. Thesis Committee is re- sponsible for approving the thesis. The thesis committee is composed of three members (including the research advisor).

The Thesis Defense can be taken in one of the following modes: In-Person, Hybrid, or Remote. The chair of the exam committee will decide the mode, taking into consideration the constraints of the student and the commit- tee members. Students taking the defense In-Person are expected to be present on campus with all committee members physi- cally present. If Hybrid is chosen, the student is expected to take the defense on campus in a video-enabled room that supports some members physically present and others re- motely. If Remote is chosen, the student and all committee members attend remotely via video conferencing.

Plan II (Comprehensive Examination) Requires completion of a minimum of 36 units of upper-division and graduate-level approved course work and successfully passing a compre- hensive examination. At least 24 of these units must be in graduate courses (200 series cours- es), a minimum of twenty of these units being Mechanical Engineering graduate courses (ME 200 or higher, excluding ME 250, ME 290, ME 297, ME 298I, and ME 299). The student must take I unit of seminar (ME 250) and no more than 7 units of directed studies (ME 290) or individual internship (ME 298I). Guidelines for preparation to the comprehensive examination are detailed in the Graduate Student Handbook.

The Department of Mechanical Engineering offers the Ph.D. degree in Mechanical Engi- neering.

Admission Applicants should have an undergraduate degree in engineering, physical sciences, or mathematics with a minimum overall GPA of 3.0 or equivalent (if GPA is not based on a 4.0 scale). A master’s degree is not required for admission to the Ph.D. program. All official transcripts and three letters of recommenda- tion must be submitted for evaluation. Foreign students and permanent residents whose first language is not English must also submit an acceptable TOEFL test score prior to admit- tance; the minimum TOEFL exam score is 550 (paper-based) or 80 (internet-based). Students in the M.S. program of Mechanical Engineering who desire to pursue the Ph.D. degree must formally apply for admission to the Ph.D. program.

The procedure for satisfying the requirements for the Ph.D. degree in Mechanical Engineering at UCR consists of four principal parts:

• 1. Successful completion of an approved

program of course work below

• 2. Passing a written and oral preliminary

examination

• 3. Successful oral defense of a written dis-

sertation proposal

• 4. Defense and approval of the dissertation

Course Work A course work plan has to be formulated by the student in coordination with their research advisor or the program graduate advisor. It is understood that changes to this may occur as the student’s research progresses. These changes should be documented after consultation with the research advisor or the program graduate advisor.

Core Course Work Before the oral defense of the dissertation proposal at least 32 units of course work must be completed. This is excluding seminar and research credits. Of these a minimum of twen- ty-four graduate units must be in Mechanical Engineering courses (ME 200 or higher, exclud- ing ME 250, ME 290, ME 297, ME 298I, and ME 299). Typically students also enroll in ME 250 and ME 297 units their first year. The student may be advised to take additional courses prior to advancement to candidacy.

Seminar Requirement The student must also complete 6 units of ME 250 (seminar) prior to graduation. One unit of ME 250 is offered each quarter. These units do not have to be completed before the disserta- tion proposal defense.

Research Units At least 36 units of directed or thesis research credits (ME 297 or ME 299) must be taken prior to graduation.

Courses taken as part of the Ph.D. requirement in Mechanical Engineering at UCR can be used to satisfy the course requirements for an M.S. in Mechanical Engineering at UCR and vice versa. Normative Time to Degree Five years

Refer to the department’s graduate program guidelines for further details

Written and Oral Preliminary Examination The examination aims to screen candidates for pursuing doctoral studies. It is administered by the graduate program committee and is composed of two sessions:

Session 1: Written Examination

Session 2: Oral Examination

Normally, both sessions are completed within a four-week period. The written examination is designed to test understanding of gradu- ate-level mechanical engineering concepts and methods. It covers three subject areas to be selected by the student among the follow- ing: materials structure & properties, control systems, engineering analysis, fluid mechanics, heat transfer, thermodynamics, solid me- chanics. Students are strongly encouraged to complete the relevant graduate-level course work for the selected subject areas. For details, consult the departmental guidelines. The oral examination assesses the student’s ability to conduct independent research. Consult depart- mental guidelines for details. The preliminary examination is normally offered once every year at the beginning of the summer session.

Dissertation and Final Oral Examination After successfully completing the preliminary examination, the student, with advice from the advisor, recommends a qualifying committee and prepares a dissertation proposal. The disser- tation proposal consists of a written document and an oral presentation or defense. Typically, the student submits a dissertation proposal to the qualifying committee within one year after successfully completing the preliminary examination and completion of the required 24 units of graduate core courses. The qualifying committee chair normally schedules an oral de- fense within one month of the written proposal submission. The presentation is given only to the qualifying committee members. The student is advanced to candidacy after successfully com- pleting this examination and all coursework.

After completing the dissertation research, a written draft copy of the completed dissertation must be submitted to the dissertation commit- tee for review, evaluation, and determination of whether the draft thesis is ready for oral defense. Once a draft has been approved for defense, an oral defense of the dissertation is scheduled and is open to the entire academic community. This defense consists of a presen- tation, followed by a question-and-answer pe- riod conducted by the dissertation committee and the audience. After successfully defending the dissertation, the candidate must submit final copies of the dissertation that comply with the format requirements set forth by the Gradu- ate Division. Copies are given to the department and the dissertation advisor, in addition to those required by the Graduate Division.

Consult departmental guidelines for appoint- ments to qualifying and dissertation committees.

Refer to the department’s graduate program guidelines for further details. Format for Oral Qualifying Exam and Final Defense The Oral Qualifying Exam and Final Defense can be taken in one of the following modes: In- Person, Hybrid, or Remote. The chair of the exam committee will decide the mode, taking into consideration the constraints of the student and the committee members. Students taking the exam or defense In-Person are expected to be present on campus with all committee mem- bers physically present. If Hybrid is chosen, the student is expected to take the exam or the de- fense on campus in a video-enabled room that supports some members physically present and others remotely. If Remote is chosen, the student and all committee members attend remotely via video conferencing.
