Transcript: Easy for panelists to understand the testing procedure. Ice Cream Advantages During this difference test, it was important that the product stayed as cold as possible in order to prevent any melting. This required scooping a sample and returning prepared samples to the freezer before they were given to panelists. Complexity of reducing fat and maintaining sensory properties Disadvantages Triangle test Experimental Design Tests were conducted under red light Panelists were asked to choose the odd sample Panelist testing Materials and methods Fat overview Results Table 2. Binomial Statistics Data Ingredients: Skim Milk, Polydextrose, Sorbitol, Maltodextrin, Contains 2% or less of Grade A Whey, Carob Bean Gum, Cellulose Gum, Mono & Diglycerides, Guar Gum, Food Starch-Modified, Polysorbate 80, Carrageenan, Vanilla Extract, Vanillin, Sucralose, Acesulfame Potassium, Vitamin A Palmitate, Caramel Color, Annatto (for color) A triangle test was chosen because it can determine which sample is the odd one out instead of identifying a specific trait that is different. Ho: There is no difference between the regular ice cream and fat-free ice cream Ha: There is a significance difference between the regular ice cream and fat-free ice cream. Health concerns This test was used to see if the panelists could determine the odd sample between three samples. Discussion There is a significant difference between the two ice cream products One Create new sensory tests, but instead test for preference or liking rather than noticeable difference Customers who prefer non-fat ice cream may prefer the different taste as well Two Research a "reduced-fat" version of ice cream Gives ice cream mouthfeel and taste of normal ice cream Gives customers a healthier alternative to the normal ice cream Conclusions Each panelist received: 1. 3 samples of ice cream with spoons 2. Rinsing: Crackers, warm water (in styrofoam cup), room temperature water (in wax cup). 3. A ballot. 6 possible sample orders: AAB, ABA, BAA, BBA, BAB, ABB Rinse protocol: Before every sample, rinse mouth with warm water, then consume part of a cracker then rinse mouth with room temperature water Implications The test was conducted in 376 Bevier with a temperature of 25ºC and a relative humidity of 33%. Ingredients: Milk, Cream, Skim Milk, Sugar, Corn Syrup, Contains 2% or less of Vanilla Extract, Vanillin, Carob Bean Gum, Guar Gum, Carrageenan, Mono & Diglycerides, Cellulose Gel, Cellulose Gum, Annatto for color. High-fat diets can be associated with cancer, heart disease and diabetes Diets high in fat lead to cholesterol accumulation in the blood (1) It also lead to weight gain and decreased metabolic efficiency (2) Problem: Some consumers are concerned with the overconsumption of dietary fat which has led the UIUC Dairy Company to develop a new fat-free ice cream. Objective: This study wants to determine whether or not there is a significant difference between regular vanilla ice cream and fat-free vanilla ice cream. Fat-Free Two routes for new studies References Prone to human error. 0.00<0.05 Regular There were 7 female panelists and 4 male panelists. Panelists do not require training. Reject the null hypothesis Group 5: Carol Chou, Lauren Killian, Karen Herdiman, Josh Warren, Adam Radi, and Jeff Sada UIUC FSHN 302 - Sensory Evalulation of Foods 2 October 2014 Previous Findings Product handling Fats are essential to the body for energy storage, insulation, and cushioning of organs. Saturated fats do not have any double bonds between carbon and hydrogen atoms. These are solid at room temperature. Unsaturated fats have a double bond between carbon atoms. These are liquids at room temperature. Table 1. Panelist Responses to Ice Cream Triangle Test Difference Testing Addition of fat to vanilla ice cream increased buttery and creamy notes and mouthcoating(3) Coldness, ice crystal perception and melting rate decreased with fat addition (3) Fat-free vanilla ice cream had lower viscosity, smoothness and mouthcoating properties compared to full fat (4) Sensory and instrumental analysis Used triangle difference test Compared 3 products to find odd one out Reject null hypothesis Accept alternative Fat is responsible for the taste and mouthfeel of normal ice cream There were 11 panelists between the ages of 18-25. The amount of sample codes may get confusing. Sufficient evidence to reject the null hypothesis Accept the alternative: There is a significant difference between the regular vanilla ice cream and the fat-free vanilla ice cream 1.[MedlinePlus] National Institutes of Health. 2013.

Transcript: HTAs or Hierarchically Tiled Arrays, whose objects are arrays divided into tiles and which may be distributed across a mesh of processors, allow the expression of parallel computation and data movement by means of indexed assignment and computation operators that overload those of the host language. Overall, HTAs are a powerful tool for the design of parallel algorithms. UICU stands for University of Illinois at Urbana-Champaign The location where it was created. HTA itself isnt a programming language, but a data structure that can be implemented in any language. UICU has implemented this datastructure in C++ and MATLAB Note: A Monte Carlo algorithim is one that utilizes randomness HTA-uiuc HTA Addressing Synax: Curly braces are used to index the tiles while parenthesis are used to access elements. C{ row, column }( row, column ) Example: C{2,1}{1,2}(1,2) translates to: go to the block in the second row and first column of C (C{2,1}). Then go to the first row and second column of C{2,1} ( C{2,1}{1,2}). Finally access the element in the first row and second column of C{2,1}{1,2}. HTA Creation Note: Code examples are writen in MATLAB Non-Homogeneous Example 2: Estimation of pi using parallel Monte Carlo High Level Operations in HTA People Involved A as the partition of B Example 3: Jacobi Relaxation: each element is replaced by the average of it's four neighbors. B as the partition of C Algorithm implementation using HTC Example 2: . . . What is HTA-uiuc? HTA Addressing C as the partition of D Why did they make HTA? C( 1, 1:3 ) C( 2, 1:3 ) Ranges may be selected using the begin:step:end notation. The step is optional and if left out is assumed to be one.Furthermore a single : can be used to present all possibles values for a dimension. In the diagram C is an HTA split into 2x2 tiles of 2x2 tiles of 2x2 elements each C{2, :}(1:2:4, 1:3) means select the blocks in the second row of C. Then in those blocks for each row starting at 1 and stepping 2 until 4 (so rows 1 and 3) select the elements in the columns from 1 to 3. Note: HTA arrays are 1-index based. Two Types of HTA You can see from the diagram that C{2,1}(1,4) and C(5,4) both access the same element as C{2,1}{1,2}(1,2) Conclusions By: Gabriel Pita and Brian Vermillion HTA stands for Hierarchically Tiled Array They were inspired by two recently proposed languages for parallel processing. Coarray Fortran UPC (Unified Parallel C) HTA provides an easier way to access and process data by organizing it a hierarchy and allowing for operations to applied to whole chunks of data or "tiles" in parallel. Tiled array vs Partitioned array Example: C( : , 1:3) means for all rows select the elements starting in column 1 and ending in column 3 Selecting ranges in an HTA David Padua - Professor of Computer Science, University of Illinois at Urbana-Champaign and a researcher of Parallel Computing María J. Garzarán - Research Assistant Professor at the Computer Science Department of the University of Illinois at Urbana-Champaign Basilio B. Fraguela - Associate Professor at Universidade da Coruna Collaborators : Christoph Von Praun Gheorghe Almási Dan Hoeflinger Diego Andrade Luiz De Rose Jose Moreira Graduate students: Ganesh Bikshandi Jia Guo James Brodman HTA was developed in 2003 to provide a data type that facilitates parallel programming and programming for locality. HTA's are tiled arrays where each tile is either a partitioned array or a hierarchically tiled array. Tiled array - an array that is partitioned into subarrays in such a way that adjacent subarrays have the same size along the dimension of adjacency Homogeneous repmat - replication circshift- circular shift. circshift(h , [0, -1]) moves all tiles in h left by one and moves the leftmost tile all the way to the right. circshift(h, [1,0]) would similarly shift the tiles in h down by one. transpose - performs the transpose operation from linear algebra (moves tile in position i j to j i) Example 1: Cannon’s algorithm for matrix multiplication It has a time complexity of O(n) and uses O(n^2) processors (servers). The naive algorithm for matrix multiplication has a time complexity of O(n^3). References: Creation of an HTA F from 6x6 Matrix M: rows 1, 3 and 5 and columns 1, 3 and 5 are delimiters for the HTA. This creates a 3x3 HTA with tiles of size 2x2. Tiles of an HTA can further be divided, creating a nested hierarchy. Homogeneous HTA's not only have the same size as their neighbors along the dimension of adjacency, but they will also agree in the number and position of the partitions along that dimension HTA Creation HTA's Nested Example with bottom up tiling: C = hta(D, {[1,3,5,7,9],[1,4,7,10]}); B = hta(C, {[1,4],[1,2,3,4]}); A = hta(B, {[1,2],[1,2]});


Transcript: Raheem Butt Secretary Plans for the Semester Trumping Islamophobia UMMA Executive Board Maryam Sultan President Mental illness is often misunderstood in today’s social context. People afflicted with mental disorder are seen as violent perpetrators, dramatic actors with personality defects, and weak individuals who lack willpower. Often they are told that they are “going through a phase” or to “just get over it”. UMMA and Dr. Sarah N. Syed of the Khalil Center discussed the stigma behind mental iIlness, with Dr. Syed as a post-doctoral fellow in clinical psychology at the Khalil Center in Glen Ellyn IL. Sana Khadri Fundraising Behind the Veil of Our Identity: Deconstructing Gender Norms Ayesha Patel Vice President Sarah Khan Advertising We presented our first open mic event “Poetic Justice“ in which students were encouraged to share their original pieces ranging from spoken word to song. The topic was identity and our goal was to enable understanding through artistic expression. In this event, we embraced the power of words and the influence they have on bringing social change. Danish Majid Fundraising Yazen Affaneh Outreach/Networking Past Events UMMA UIUC’s gender-dialogue provided a safe(r) space for discussing how societal pressures influence our perceptions of masculinity and femininity as well as how each sex [amusingly] fails in its attempt to understand the other. The event featured both segregated and coed conversations, so everyone had some time to roast each other. Farah Hussain Treasurer UMMA hosted a discussion in which we examined the hidden and unhidden, conscious and subconscious, micro- and macro-divisions within the Muslim community, also known as the “Ummah.” Topics of discussion included, but were not limited to, racism, sexism, classism, and sectarianism. The event also featured an interactive portion in which participants were able to anonymously share personal narratives. The Stigma of Mental Illness UMMA Officers Exec Board Cont. - Solidarity with other organizations like SJP, BSFR, CUTES, MSA, Thaakat, MSA, etc. - Activism - GBM monthly - Suggestions? Poetic Justice: Open Mic This event featured an informative and interactive panel as we explored the historical roots of anti-Muslim sentiment in the U.S, recognized the psychological effects of media representation, discussed the underlying purpose of fear-mongering in American politics, and ultimately "trumped" Islamophobia. On the Frontlines of the Movement: A Conversation with Alderman Aaron Ammons One UMMA, One Lie UMMA UIUC Given the systematic oppression of African Americans, it is necessary that we continue to expand our knowledge on the history of black activism and discuss the future of the black liberation movement. UMMA and Alderman Aaron Ammons partnered together and discussed the struggles faced by African Americans, mass incarceration, electoral politics, and how to overcome systemic injustice.
