\begin{array}{|cc|cc|cc|} Grades at a point support have a higher variance than grades of SMU, which similarly have a higher variance than grades of panels. Once the grade change form is received in the University Registrar's Office and processed, the student may view it using my.SMU. The block scale is 15x15x15m and light gray curve is the original drill hole data. Flexible change of support model suitable for a wide range of mineralization styles. This histogram can then be used to calibrate estimation parameters. 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.. About Kelley Direct Although better than the affine correction, the shape change is unrealistic. The decrease in variance for a specified SMU size should be quantified. \]. Reports of Grade Distribution by Instructor and Semester. Resource estimates often produce smoothed block grade distributions with much lower block grade variability than true selective mining unit (SMU) block grade distributions. 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 … Change of Support and the Volume Variance Relation. Meanwhile, as the slogan of the SMU suggests, it is ‘a different U’, and the difference is seen in how SMU assesses students. Grade Distribution information is available beginning with the Fall 1994 term. 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. Due to the spatial variability of ore deposits, one cannot realistically recover all of the estimated “in-situ” resource. Viewing Your Grades You may view and print your end-of-semester grades using my.SMU. Spring 2018. 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. 310-434-4000 CONTACT US. The variance reduction is performed by scaling the coefficients by a change of support factor related to the variance reduction (Rossi & Deutsch, 2013). \], \[ The variance reduction from data to an SMU is known from the average variogram. 0.088 &= 0.067 + 0.021 \\ service.centre@smu.ca Highly continuous deposits will experience a less drastic mixing of highs and lows when the data is scaled up. The Grade Distribution Report represents a statistical analysis of grades given in each course and section. The "Ideal" Reserves. The affine correction reduces the variance of the distribution without changing its shape. ), \[Var(v_i,V_1)=\frac{1}{6}\sum_{i=1}^6(z_{vi}-m_{V1})^2=0.122\], \[Var(V,A)=\frac{1}{3}\sum_{i=1}^3(m_{Vi}-m_A)^2=0.021\], \[\begin{aligned} The act and regulations are very lengthy, and for that reason, SMU has issued its ow… 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 variance of a distribution with respect to its support is characterized by the dispersion variance notation \(D^2(v,V)\) where \(v\) represents a small support of the values, and \(V\) represents a larger support of the mean. Querying Grade Distribtion. \hline The geologic continuity of the variable has a significant impact on how the shape of the distribution will change. 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. The grade of an SMU can be thought of as an average of many smaller support samples such as drill hole composites. technique calculates the grade distribution functions using a conventional UC. 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). 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. grade represents, and a change-of-support model, like the DGM, is used to predict the distribution of grade at different supports. An important factor contributing to the change in shape is the geologic continuity of the variable in question. The VCF can provide an indication of the impact of the change of support. Grade distributions of highly structured or discontinuous deposits may experience significant changes of shape as the data is scaled up. (or the page you requested is simply not there). This assessment would be based on the impact that various sizes of mining equipment, and thus various SMU sizes, would have on dilution for the given operation. Chilès, J.-P., & Delfiner, P. (2009). 0.060 & 0.018 & 0.472 & 0.641 & 0.040 & 0.218 \\ The volume-variance relationship: A useful tool for mine planning. Where \(r_v\) is chosen such that the variance of the block values matches that predicted above and \(\omega\) is a measure of dissemination which is typically chosen as \(p\) for disseminated deposits and 1 for highly structured deposits. As the support of a grade increases, so To find what you’re looking for, you can use the navigation bar or the search form at the top of this page. Note as the continuity of the variable decreases the distributions become increasingly low variance and converge to the mean value. Diverse courses and programs from diplomas and certificates to bachelor and graduate degrees. As we are interested in the dispersion variance of blocks \(V\) within some domain \(A\), we re-arrange the above equation to: The dispersion variance of the data within the domain is equal to the sample variance, \(D^2(v,A)=\sigma^2\), and the dispersion variance of point data within the block, \(D^2(v,V)\), can be calculated from the variogram model. There are two main factors that are involved in this smoothing. SMUworks Summer Application: The SMUworks Summer 2020 application is now closed. Spring 2016 Santa Monica College. 7.18: GradeBook.java 2: // Grade book using two-dimensional array to store grades. Inquiries can be directed to Carmen Burke at smuworks@smu.ca . There are a number of methods to do this with the simplest being the Affine Correction. This 5 to 7 order of magnitude increase in support from the data and the SMU is an important consideration when estimating long term recoverable resources. Mining Engineering. If the composite length matches the SMU dimension discretization in the \(z\) direction should be set to one to avoid artificially increasing the average variogram. Final letter grades will be based on the curve (grade distribution) of the entire class and posted on my.smu.edu Homework Assignments. The volume variance relation can provide the grade distribution representative of what will be mined. University Registrar Southern Methodist University Laura Lee Blanton Building Suite … The mean of the SMU grades in each panel corresponds, or is conditioned to, the OK estimate of the panel grade. 0.770 & 0.974 & 0.520 & 0.829 & 0.320 & 0.699 \\ 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): \[z(\mathbf{u})=\sum_{p=0}^{n_p}\phi_pH_p(y(\mathbf{u}))\]. Where \(\phi_p\) is the \(p\)-order polynomial coefficient and \(H_p(y(\mathbf{u}))\) is the \(p\)-order Hermite polynomial; \(n_p\) is typically set to 100. Spring 2020. This provides a target for estimation of recoverable reserves. Grade distribution can be done in a number of ways other than actually posting the grade in a public place. A change of shape model is necessary to accurately predict recoverable resources. A change of support model predicts how grade distributions change with volume support considering only data and statistics of the composited drill hole data. For courses with more than one section, the report also provides totals for all sections. Students can access the student application at smu.ca/smuworks, which will be available from February 24 th until March 8 th. \hline The mean and variance of all points within the domain is 0.463 and 0.088, respectively. If the cutoff is below the mean, as in \(\mathbf{z}_{\mathbf{c1}}\), the estimated tonnage above this cutoff increases as support increases. A hypothetical grade distribution is shown below. SMU Canvas helpdesk: ... paper study and presentation and exams) will be posted on Canvas. Department Subject Course Section Instructor A B C D F IX NP P RD W Total Fall 2019 Grade Distribution by Instructor 91 1 2 13 3296 DASTIN E R 11 6 215 5 30 Understanding how a grade distribution will change as it is scaled up to a larger support is a critical component of assessing recoverable resources. The data and variogram are the same for both grade tonnage curves, only the support has changed. Currently, faculty have been instructed to continue grading along the normal letter grade distribution. \], The variance of points within the blocks is: \[Var(v_i,V_1)=\frac{1}{6}\sum_{i=1}^6(z_{vi}-m_{V1})^2=0.122\], \[Var(v_i,V_2)=\frac{1}{6}\sum_{i=1}^6(z_{vi}-m_{V2})^2=0.030\], \[Var(v_i,V_3)=\frac{1}{6}\sum_{i=1}^6(z_{vi}-m_{V3})^2=0.048\], \[Var(v,V)=\frac{1}{3}(0.122+0.030+0.048)=0.067\], And the variance of blocks within the domain is: \[Var(V,A)=\frac{1}{3}\sum_{i=1}^3(m_{Vi}-m_A)^2=0.021\], The sum of the variance of the components equals the total variance of the data: \[\begin{aligned} A hypothetical grade distribution is shown below. As shown above, the total variance in a domain \(A\) is equal to the sum of the average variance of points within blocks of some volume \(V\) and the variance of those blocks within the domain \(A\) (Isaaks & Srivastava, 1989): This relationship is known as Krige’s Relation. 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. 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: … McGraw Hill. The data support distribution of an attribute will have greater variance than the block distribution of the same attribute (Rossi & Deutsch, 2013). 1200 Environmental Challenges. \end{aligned}\], (Chilès & 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. The DGM works on a Gaussian transform of the original variable. 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. A small diameter core sample could be high grade or low grade. Grade Distribution Grade Distribution Report. In order to proceed to an SMU grade distribution inside each panel, the estimated sample distribution has to be ‘squeezed’ to lower the variance without altering the mean. 0.088 &= 0.067 + 0.021 \\ This course is an interdisciplinary introduction to environmental science. \hline Delivery Address. 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. \hline An internal broken link that we haven’t noticed yetWe’d appreciate it if you took a moment to report it. 497). The DGM provides a robust change of shape model. 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. A 5x5x5 discretization is considered sufficient to provide a reliable estimate of the average variogram (Isaaks & Srivastava, 1989); however, further consideration must be given to the number of discretization points in the direction of drilling. Like SUTD, getting an A+ for a module in SMU actually gives the student an additional 0.3. The central limit theorem tells us that the distribution will converge to the Gaussian distribution as support increases. This is the variability of the data of smaller support within the larger volume. 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. Grades reported later are not captured and reported in the table (all of Law is displayed separately for this reason). Springer Science & Business Media. Change of support models may also be used to assess the value of selectivity. 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. Spring 2019 Fall 2018. It typically takes 2-4 weeks after a semester ends before we obtain its grade data. UC accomplishes all of this using a method called the Discrete Gaussian Model. Year 3 FINA 2360 Business Finance I FINA 3361 Business Finance II mean grade of the panel, the distribution of SMU grades within the panel –which can be summarized as the variance of SMU grades with respect to the average panel grade for a specific simulation, or with respect to the global average value of the panel–, the expected proportion of SMUs and their grade, above a specified cutoff, etc. 61–91). The SMU geometry depends on the mining method, equipment size and selectivity characteristics of the deposit. SMC Class List + Grade Distribution . John Wiley & Sons. \end{aligned}\]. 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. Grade Reports are not mailed. 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. 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. SMU uses the cumulative GPA (Grade Point Average) criteria to recognize students with academic excellence and it is based on a 4.0 system. m_{V1} & m_{V2} & m_{V3} \\ Department and college totals reflect composite grade distribution. 3.0 credit hours. The variance correction factor (VCF), or \(f\), is commonly defined as the ratio of block variance to sample variance: \[f = \frac{D^2(V,A)}{D^2(v,A)} = \frac{\sigma^2-\overline{\gamma}\left(V,V\right) }{\sigma^2}=1-\frac{\overline{\gamma}\left(V,V\right)}{\sigma^2}\]. Grades for all course assignments (i.e., homework, project, paper study and presentation and exams) will be posted on Canvas. Open pit SMU sizes range from 5x5x5m for a highly selective operation to 20x20x15m for large bulk-tonnage porphyry deposits. The value of the recoverable resource for a given selectivity is compared to the operational cost of achieving such selectivity. Please visit PROFFINDER.COM for grade distribution. Blackburn Press. The high and low values average together and the larger the support the less variable and more symmetric the distribution becomes (Isaaks & Srivastava, 1989). The data available for mineral resource estimation primarily comes from diamond drill core or reverse circulation (RC) cuttings. 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. Using an appropriate change of support model, the resource modeler can anticipate the expected distribution of grades at the SMU scale. This problem is probably caused by one of these: A search-engine link that is out-of-dateSearch engines usually correct these automatically… eventually. 0.770 & 0.974 & 0.520 & 0.829 & 0.320 & 0.699 \\ 0.060 & 0.018 & 0.472 & 0.641 & 0.040 & 0.218 \\ The highest GPA score attainable is 4.0 instead of 5.0. A typical three meter long diamond drill core sample represents 5-25 kg of material while an open pit SMU may represent 325-20,000 tonnes of material. \end{array} Var(v,A) &= Var(v,V) + Var(V,A) \\ 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. The grade within mineral deposits is variable at all scales. 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. Consider the following small example of eighteen small scale values \(v_i,i=1,...,18\) that define a domain \(A\) (the rectangular box): \[ Geostatistics: Modeling spatial uncertainty (Vol. Important Summer 2020 Dates: The 0.175% Cu cutoff grade is below the mean in this example. Choose the program that’s right for you at Saint Mary’s University. When we get grades for a new semester, we'll post a banner at the top of this page for at least a week. All grade distribution information is provided directly from the colleges through a public records request. 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. Mon-Fri, 9am-4:30pm: 902-420-5582, Other inquiries: 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. Homework assignments will be posted on the course webpage. \end{array} A direct relationship exists between the point support variance, the variance of points within the SMU volume and the variance of the SMU volume within the domain. The distribution of SMU scale grades can then be determined by scaling the anamorphosis function by a support coefficient \(r\): \[z_V(\mathbf{u})=\sum_{p=0}^{n_p}(\phi_pr_v)^{\omega}H_p(y(\mathbf{u}))\]. The following dynamic figure illustrates how an up-scaled distribution of copper changes as a function of the variogram. Details regarding the fitting of Hermite polynomials are presented by Chilès & Delfiner (2009) and Machuca-Mory, Babak, & Deutsch (2008). 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. By restricting the total number of data used for the estimate, the modeler can target the expected distribution from the change of support model, particularly above a cutoff of interest. If the composite length is half the SMU dimension the discretization should be two. Often, the SMU size is increased to account for imperfect information at the time of mining and other considerations. As the volume or support of the core sample increases the observed variability will decrease and the distribution will become more symmetric. Students consider scientific methods, the scale and magnitude of environmental variables, societal pathways and impediments to solving environmental problems, and critical thinking about environmental issues. 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. 0.493 & 0.623 & 0.272 \\ \hline 1: // Fig. Spring 2017. However, SMU does have the Grade Replacement Repeat policy that students may take advantage of, regardless of their year. 0.572 & 0.564 & 0.409 & 0.866 & 0.059 & 0.296 \\ Consideration must be given to the number of discretization points to achieve a stable result. \begin{array}{|c|c|c|} Applications were due by February 16th at 11:59pm. Machuca-Mory, D. F., Babak, O., & Deutsch, C. V. (2008). As the data is scaled up the distribution will become progressively more Gaussian in shape. In J. L. Deutsch (Ed. If the data are grouped into three 3x2 blocks \(V_i,i=1,...,3\) we get the configuration below: \[ 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. Mon-Fri, 9am-4:30pm: 902-420-5400. This investigation may provide justification for split benching (ie. SMU uses the cumulative GPA (Grade Point Average) criteria to recognize students with academic excellence and it is based on a 4.0 system. 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. As the block size increases the average variogram value increases and the block support variance must decrease. 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 *). This does not depend on any statistical assumptions such as stationarity. The shape of the distribution will change as support increases. Mineral resource estimation. 7.18: GradeBook.java 2: // Grade book using two-dimensional array to store grades. An introdruction to applied geostatistics. my.SMU is a web based application offering a variety of features for Students, Faculty, Staff and SMU Affiliates. Parker, H. M. (1980). An important aspect of the volume variance relation is that variances are additive. A change of support model is useful when evaluating recoverable resources. Krige’s Relation and the additivity of variances tells us how variance changes with support. A selective mining unit (SMU) may be considered the smallest volume that a mining operation can select between ore and waste (Parker, 1980). my.SMU is a web based application offering a variety of features for Students, Faculty, Staff and SMU Affiliates. The "Ideal" Reserves. One limitation of change of support models is that only internal dilution is considered. Tips (click me to see)!This site has been abandoned. For legal compliance reasons, MSU only provides us with grade … \hline 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. If the cutoff grade is above the mean grade, as in \(\mathbf{z}_{\mathbf{c2}}\), the estimated tonnage exceeding this grade will decrease as the support increases. 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: \[\overline{\gamma}\left(V,V\right) = \frac{1}{V \cdot V} \int_{V} \int_{V} \gamma(y-y') dy dy' \approx \frac{1}{n \cdot n} \sum_{i=1}^n \sum_{j=1}^{n} \gamma({\mathbf u}_i - {\mathbf u}_j)\]. For assistance using my.SMU, go to the … These data represent a small volume relative to the volume relevant for mining. Santa Monica, CA 90405. 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.
