Final letter grades will be based on the curve (grade distribution) of the entire class and posted on my.smu.edu Homework Assignments. \begin{array}{|cc|cc|cc|} 497). With all change of support models, the distribution of SMU grades maintains the same mean while the variance is reduced by the variance correction factor from the average variogram. A mis-typed URL (or an out-of-date bookmark/favourite)Please check your spelling. SMU Canvas helpdesk: ... paper study and presentation and exams) will be posted on Canvas. Querying Grade Distribtion. SMU uses the cumulative GPA (Grade Point Average) criteria to recognize students with academic excellence and it is based on a 4.0 system. my.SMU is a web based application offering a variety of features for Students, Faculty, Staff and SMU Affiliates. For classes taken Fall 2017 and later, if you made a D+ or lower in a course, you may repeat the course here at SMU and the second grade will be used in place of the first grade to calculate your SMU GPA. Viewing Your Grades You may view and print your end-of-semester grades using my.SMU. The 0.175% Cu cutoff grade is below the mean in this example. The block scale is 15x15x15m and light gray curve is the original drill hole data. The function is defined by Hermite polynomial expansion up to order \(n_p\), where the distribution of the transformed data is (Machuca-Mory et al., 2008): \[z(\mathbf{u})=\sum_{p=0}^{n_p}\phi_pH_p(y(\mathbf{u}))\]. When we get grades for a new semester, we'll post a banner at the top of this page for at least a week. The black curve represents the distribution for the data support, the red curve with lesser variability represents a small SMU support, and the green curve with even less variance represents a larger SMU support. The variance correction factor (VCF), or \(f\), is commonly defined as the ratio of block variance to sample variance: \[f = \frac{D^2(V,A)}{D^2(v,A)} = \frac{\sigma^2-\overline{\gamma}\left(V,V\right) }{\sigma^2}=1-\frac{\overline{\gamma}\left(V,V\right)}{\sigma^2}\]. Santa Monica, CA 90405. Using a similar approach, the information effect can be taken into account when calculating local recoverable reserves using UC by panel grade. SMU support also influences the average variogram value. Fall 2016. The DGM requires an anamorphosis function to be fit. For example, distributing grades in class, asking students to stop by during office hours, or leaving sealed, identified envelopes with Departmental Secretaries for students to pick up at their convenience. Parker, H. M. (1980). All kriged estimates will be smooth, but one may employ a restricted search in an effort to control the degree of smoothing for an interim estimate. Consider the following small example of eighteen small scale values \(v_i,i=1,...,18\) that define a domain \(A\) (the rectangular box): \[ 0.493 & 0.623 & 0.272 \\ Delivery Address. As the support of a grade increases, so Please visit PROFFINDER.COM for grade distribution. TORONTO, March 3, 2020 /CNW/ - Summit Industrial Income REIT ("Summit" or the "REIT") (TSX: SMU.UN) announced today that it had waived conditions and will acquire 100% of a Class A temperature-controlled single tenant distribution facility in Guelph, Ontario.The 282,133 square foot building is LEED Gold Certified and is the main distribution facility for Central and Eastern Canada for … Journel, A., & Huijbregts, C. (1978). A quantile-quantile transformation from one distribution to the other is performed; however, the mean is not preserved if the distributions are not exactly log-normal. Open pit SMU sizes range from 5x5x5m for a highly selective operation to 20x20x15m for large bulk-tonnage porphyry deposits. Var(v,A) &= Var(v,V) + Var(V,A) \\ UC consists of estimating the grade distribution on SMU support within a panel, conditioned to the estimated panel grade, usually based on ordinary kriging (OK) or simple kriging (SK) with local mean to accommodate a possible lack of stationarity (ie when the average grade varies within the deposit). (or the page you requested is simply not there). This investigation may provide justification for split benching (ie. Using an appropriate change of support model, the resource modeler can anticipate the expected distribution of grades at the SMU scale. The distribution of estimated grades should not match the change of support distribution exactly as additional, site specific, geologic and operational dilution should also be considered. Spring 2018. A recoverable resource model is one that takes into consideration aspects of the mining operation to quantify dilution that may affect the proportion of material above a defined cutoff grade. Use the slider at the bottom to step through varying measures of spatial continuity. 7.5m blocks yield 52% of the total tonnage above cutoff at a grade of 0.310% Cu while 15m blocks yield 56% of total tonnage above cutoff at a grade of 0.289% Cu. Grade Distribution Grade Distribution Report. The SMU geometry depends on the mining method, equipment size and selectivity characteristics of the deposit. The practical application of change of support models include the following. Fall 2019. \end{array} Oxford University Press. SMU uses the cumulative GPA (Grade Point Average) criteria to recognize students with academic excellence and it is based on a 4.0 system. 7.18: GradeBook.java 2: // Grade book using two-dimensional array to store grades. Mon-Fri, 9am-4:30pm: 902-420-5582, Other inquiries: Grade Distribution information is available beginning with the Fall 1994 term. A change of shape model is necessary to accurately predict recoverable resources. Localised Uniform Conditioning (LUC) 395 method and then uses the calculated grade–tonnage relationships in the panels to assign a single grade value to each SMU size block. This SMU size, together with the variogram model based on the sample data, is used to the distribution estimate of SMU grades within each panel. Grade Point Table of NTU and NUS A student may receive a grade of Incomplete (I) when at least 50 percent of the course requirements have been completed with passing grades but for some justifiable reason acceptable to the instructor, he/she has been unable to complete the full requirements of the course. ChilÃ¨s, J.-P., & Delfiner, P. (2009). service.centre@smu.ca Note as the continuity of the variable decreases the distributions become increasingly low variance and converge to the mean value. Graduation Requirements To graduate from the Bachelor of Commerce program, you will need to complete 120 credit hours with a minimum cumulative grade point average of 2.0. All grade distribution information is provided directly from the colleges through a public records request. Variograms and corresponding block distributions. where is the Gaussian equivalent cut-off grade applied to the distribution of the estimated SMU grades, and where g is the standard Gaussian probability density function.. LOCAL RECOVERABLE RESERVES - UNIFORM CONDITIONING. For courses with more than one section, the report also provides totals for all sections. However, because data formats and structures change over time, you should check our Querying Help page for data conventions if you intend to query data prior to Fall 2004. Grades for all course assignments (i.e., homework, project, paper study and presentation and exams) will be posted on Canvas. University Registrar Southern Methodist University PO Box 750181 Dallas, TX 75275-0181 . If the composite length is half the SMU dimension the discretization should be two. Note the change in shape of the histogram as the support increases - the variance decreases, the maximum value decreases, the minimum value increases and the distributions become more symmetric. As the block size increases the average variogram value increases and the block support variance must decrease. The Grade Distribution Report represents a statistical analysis of grades given in each course and section. This course is an interdisciplinary introduction to environmental science. The VCF can provide an indication of the impact of the change of support. Machuca-Mory, D. F., Babak, O., & Deutsch, C. V. (2008). registrar@smu.edu Virtual Office Connect with us via Zoom Mailing Address. The variance reduction from data to an SMU is known from the average variogram. SMUworks Summer Application: The SMUworks Summer 2020 application is now closed. The act and regulations are very lengthy, and for that reason, SMU has issued its ow… \begin{array}{|c|c|c|} The shape of the distribution will change as support increases. The volume variance relation can provide the grade distribution representative of what will be mined. 61â91). 0.572 & 0.564 & 0.409 & 0.866 & 0.059 & 0.296 \\ It would only be correct for a distribution which is Gaussian at the smallest scale. Spring 2019 Fall 2018. Grade distribution can be done in a number of ways other than actually posting the grade in a public place. Grade Distribution information is available beginning with the Fall 1994 term. \hline 0.770 & 0.974 & 0.520 & 0.829 & 0.320 & 0.699 \\ An important aspect of the volume variance relation is that variances are additive. 0.088 &= 0.067 + 0.021 \\ The "Ideal" Reserves. There are a number of methods to do this with the simplest being the Affine Correction. The histogram of the drill hole data is scaled to the two block supports using the illustrated variogram model and the discrete Gaussian change of support model. Var(v,A) &= Var(v,V) + Var(V,A) \\ \end{aligned}\], (ChilÃ¨s & Delfiner, 2009; Isaaks & Srivastava, 1989; Journel & Huijbregts, 1978), Review the concept of support and the volume variance relation, Demonstrate the importance of considering a change of support model when estimating recoverable resources, Appreciate the additivity of variance and dispersion variance notation, Understand the practical application of change of support models. One drawback of using change of support models for selectivity analysis is the assumption of free and perfect selection. Understanding how a grade distribution will change as it is scaled up to a larger support is a critical component of assessing recoverable resources. A grade change must be initiated by the instructor who taught the course and authorized by the department chair and course dean of the department in which the course was offered. The relationship between original grades, \(Z\), and the normal scores, \(Y\), is fit with a series of Hermite polynomials. Grade Reports are not mailed. An \(f\) close to one suggests the two variances are similar either due to a highly selective SMU size or geologic continuity; little mixing of material will occur (Rossi & Deutsch, 2013). grade model at the SMU resolution that respects the grade- tonnage distributions of the UC panels and attempts to reflect the localized spatial grade distribution within the panel. Taking a Class as Pass/Fail 7.5m vs 15m benches) or the use of a hydraulic excavator near ore-waste contacts. John Wiley & Sons. Pursuant to the California Public Records Act, Government Code Section 6253(c), the distribution of grades attained at public institutions should be public record. McGraw Hill. The variance reduction is performed by scaling the coefficients by a change of support factor related to the variance reduction (Rossi & Deutsch, 2013). In Geostatistics (pp. \end{array} SMC Class List + Grade Distribution . \hline Highly continuous deposits will experience a less drastic mixing of highs and lows when the data is scaled up. In J. L. Deutsch (Ed. \end{array} 7.18: GradeBook.java 2: // Grade book using two-dimensional array to store grades. © Saint Mary's University | Privacy | Provide Feedback, 923 Robie Street,Halifax, Nova Scotia, CanadaB3H 3C3, Account inquiries, payment information, transcripts and confirmation of enrolment: Texas A&M class grade averages graphed by semester and professor The Grade Distribution Report only reports grades received immediately at the close of the term (Law Grade Distribution Reports are reported 60 days following the close of the term). The grade within mineral deposits is variable at all scales. It can provide a target for an estimated grade distribution, an indication of the degree of averaging that may occur and potentially highlight the importance (or not) of mining selectivity. 310-434-4000 CONTACT US. The data and variogram are the same for both grade tonnage curves, only the support has changed. A selective mining unit (SMU) may be considered the smallest volume that a mining operation can select between ore and waste (Parker, 1980). 3.0 credit hours. University Registrar Southern Methodist University Laura Lee Blanton Building Suite … Students can access the student application at smu.ca/smuworks, which will be available from February 24 th until March 8 th. A small diameter core sample could be high grade or low grade. The variance of points in the domain is the average or expected variance of points in the blocks plus the variance of blocks in the domain. The average variogram value within a volume \(V\) is denoted \(\overline{\gamma}(V,V)\) and calculated as the average variogram value for all possible pairs where both ends of the vector are in the volume: \[\overline{\gamma}\left(V,V\right) = \frac{1}{V \cdot V} \int_{V} \int_{V} \gamma(y-y') dy dy' \approx \frac{1}{n \cdot n} \sum_{i=1}^n \sum_{j=1}^{n} \gamma({\mathbf u}_i - {\mathbf u}_j)\]. By correcting the data distribution to the SMU support distribution prior to estimation, the practitioner has a target distribution for the estimated model (Rossi & Deutsch, 2013). A hypothetical grade distribution is shown below. If the data are grouped into three 3x2 blocks \(V_i,i=1,...,3\) we get the configuration below: \[ \hline Change of Support and the Volume Variance Relation. There are two main factors that are involved in this smoothing. my.SMU is a web based application offering a variety of features for Students, Faculty, Staff and SMU Affiliates. The discrete Gaussian model (DGM) is considered a more robust change of shape model than those mentioned above as it makes more reasonable assumptions. Grade Availability. MU Grade Distribution Application Tuesday, December 15, 2020 : Term This allows for students to maintain letter grades that will count toward their GPA at the end of the semester if they are satisfied with the letter grade. The grade of an SMU can be thought of as an average of many smaller support samples such as drill hole composites. Springer Science & Business Media. Correctly estimating the recoverable proportion of material above this cutoff grade is of unquestionable importance when evaluating the viability of a mining project. The high and low values average together and the larger the support the less variable and more symmetric the distribution becomes (Isaaks & Srivastava, 1989). \hline The highest GPA score attainable is 4.0 instead of 5.0. The black curve represents the distribution for the data support, the red curve with lesser variability represents a small SMU support, and the green curve with even less variance represents a larger SMU support. \]. Honours and co-operative students must maintain a minimum cumulative grade point average of 3.0. Rossi, M. E., & Deutsch, C. V. (2013). 0.088 &= 0.067 + 0.021 \\ An important factor contributing to the change in shape is the geologic continuity of the variable in question. Using a similar approach, the information effect can be taken into account when calculating local recoverable reserves using UC by panel grade. The average variogram, \(\overline{\gamma}(V,V)\), is the expected variance of points inside a volume \(V\) and can be calculated from the variogram model and the SMU geometry. A small \(f\) value indicates the opposite and there will be a significant change in variance and resources above cutoff, at the selected SMU scale. This is typically done by comparing SMUs of varying size as shown below: Drill hole data and variograms (top left and right) with scaled histograms and corresponding grade tonnage curves for 7.5m and 15m cubic blocks. Like SUTD, getting an A+ for a module in SMU actually gives the student an additional 0.3. For legal compliance reasons, MSU only provides us with grade … 1: // Fig. To complete a major in Marketing, students must attain a minimum grade point average of 2.2 in MKTG 2270 and the 3rd and 4th year MKTG courses (as indicated below by *). Often, the SMU size is increased to account for imperfect information at the time of mining and other considerations. Details of the methods are discussed in the geostatistical literature (ChilÃ¨s & Delfiner, 2009; Isaaks & Srivastava, 1989; Journel & Huijbregts, 1978). Singapore Management University: SMU: Suomen Merimies-Unioni (Finnish: Finnish Seamen's Union) SMU: Sony's Marvel Universe (fan fiction) SMU: Start Me Up: SMU: Storage Management Utility (data storage) SMU: Special Make Up: SMU: Strategic Market Unit: SMU: Secours Médical d'Urgence (French: Emergency Medical Relief; various organizations) SMU: Software Maintenance Update (Cisco) SMU: … The geologic continuity of the variable has a significant impact on how the shape of the distribution will change. For assistance using my.SMU, go to the … UC accomplishes all of this using a method called the Discrete Gaussian Model. An internal broken link that we haven’t noticed yetWe’d appreciate it if you took a moment to report it. Cite this lesson as: Harding, B. E., & Deutsch, C. V. (2019). This assumption of the permanence of shape is limiting as artificial minimum and maximum values are introduced and we know the distribution will become more symmetric as the support increases. As the data is scaled up the distribution will become progressively more Gaussian in shape. grade represents, and a change-of-support model, like the DGM, is used to predict the distribution of grade at different supports. The Family Educational Rights and Privacy Act of 1974 is a federal law that grants students the right to inspect, obtain copies of, challenge, and, to a degree, control the release of information contained in their education records. \hline The value of the recoverable resource for a given selectivity is compared to the operational cost of achieving such selectivity. The change of support from composited drill hole data to a practical mining scale is important for the estimation of recoverable resources. The following dynamic figure illustrates how an up-scaled distribution of copper changes as a function of the variogram.
