Prusaprinters Alice 3D MODEL ONLY reddadsteve VIEW IN BROWSER updated 5. 2. 2019 | published 5. 2. 2019 Summary Alice, from the Dilbert comic strip by Scott Adams. She is depicted as being one of the hardest-working engineers in the comic, however she suffers all the problems of being a female engineer. No supports are required. If you have the right filament colors, no painting is needed. The completed model is 210mm tall after assembly. This model is in proportion to my Dilbert series. Enjoy! Toys & Games > Action Figures & Statues cartoon comics dilbert Rafts: Doesn't Matter Supports: No Resolution: .2 mm Infill: 10% Notes: See notes below for helpful printing and assembly instructions Building the Model Colors (there are no multiple printed pieces) Black: eye_left (includes the eyebrow) eye_right (includes the eyebrow) stand_13 text_frame_13 .. White: shirt cuff_right cuff_left text_13 (see below for optional two color printing instructions with a single extruder) .. Red (or dark pink): skirt jacket shoe_right shoe_left mouth .. Beige (or any skin color): leg_left leg_right hand_left hand_right head .. Brown: hair_top (contains a built in support) hair_top_no_support (optional if you want to do your own support) hair_bottom .. Grey (or any suitable color) briefcase Printing and assembly tips Printing Tips: Included a file hair_top_no_support which can be substituted for hair_top if you prefer to use your own support. 1-No supports are required. .. 2-I used a brim on a few pieces, use your discretion based on your own preference: -jacket is printed upside down to avoid supports, however this results in a smaller base -the legs are tallish with a small base -do NOT print the eyes with a brim .. 3-The eyes pieces contain the eyebrow and are quite small. I printed multiple copies at the same time with no brim and they came out perfect, however this part could be tricky if you have problems with bed adhesion. .. 4-hair_top contains a built in support structure that needs to be removed after printing. .. 5-In case anyone wonders how I align pieces for printing, one major consideration (besides printing without supports) is how to avoid layer stepping. For pieces that have slow curves, the smoothest finish is to have the curve vertical instead of horizontal. This is why I always have a head piece printed vertical, even if there is a much simpler way to print it. .. 6-For printing the words with a white background and black lettering, see my full instructions included with the quotes from the Dilbert series. Assembly tips: -The diagrams in the pictures section will help in assembling the model and is quite straightforward. -The model is meant to be glued together. -Since there are a number of smallish pieces, some of the pieces have tight clearances. Take care to ensure that the first layer 'squish' and any added brim is completely cleaned off. -The head only has a minimal dent for the eyes which are to be used as placement markers for aligning and gluing the eyes. -When assembling and gluing the right hand/cuff into the jacket, be sure the hand has the briefcase already hanging off it but not glued. There is no room to insert the briefcase after the hand/cuff/jacket has dried. -Remove the built in support structure from hair_top before assembly (fairly obvious but here for completeness!) -Be sure to completely test fit the head/jacket/hair/shirt combo before gluing any of the pieces. -The bottom of the skirt has the thicker side in the back. The holes for the legs will then be slightly further back. -It's easy to get the left/right legs and shoes mixed up. Sorry, but the pieces are small and there was not much room for distinction.

  • “Don't Be a Dilbert”: Transmedia Storytelling As Technical
    corrected 7/15/20 Applied Research “Don’t Be a Dilbert”: Transmedia Storytelling as Technical Communication during and after World War II By Edward A. Malone Abstract Purpose: My goal was to determine whether the U.S. Navy’s “Don’t Be a Dilbert” aviation safety campaign during World War II was a fully developed example of transmedia storytelling and whether it could be used as an illustration of transmedia storytelling in technical communication. Method: I located and gathered primary sources in the Navy’s safety campaign from archives, museums, and military and civilian publications, and then analyzed these artifacts according to the definition and attributes of transmedia storytelling in Jenkins (2007, 2011). Results: From my analysis, I found that the Navy’s use of the Dilbert myth combined multimodality with radical intertextuality in order to foster additive comprehension; it also employed a robust set of transmedia storytelling techniques. Conclusion: Tese findings suggest that transmedia storytelling was used to communicate technical information before the digital age and that the Navy’s Dilbert campaign is a potentially useful historical example for illustrating transmedia storytelling techniques. Keywords: transmedia storytelling, participatory culture, safety education, cartoon characters, history of technical communication Practitioner’s • Examines the role of transmedia communication students to Takeaway: storytelling in a high-stakes training transmedia storytelling program in which entertainment • Contributes to an understanding of supported education the history of transmedia storytelling • Provides a potential pedagogical in technical communication tool for introducing technical Volume 66, Number 3, August 2019 l Technical Communication 209 Applied Research "Don't Be a Dilbert" Introduction Most people are familiar with Dilbert, the main character in Scott Adams’ comic strip about an engineer who, in some ways, epitomizes the white- collar worker in corporate America.

    Paper ID #6139 Bazinga! You’re an engineer.. you’re ! A Qualitative Study on the Media and Perceptions of Engineers Rachel McCord, Virginia Tech Rachel McCord is a second year graduate student in the Department of Engineering Education at Virginia Tech. Her current research interests include motivation, conceptual understanding and student use of metacognitive practices. She received her B.S. and M.S. in Mechanical Engineering from The University of Tennessee. Her advisor is Dr. Holly Matusovich. Page 23.240.1 Page c American Society for Engineering Education, 2013 Bazinga! You’re an engineer…you’re___! A Qualitative Study on the Media and Perceptions of Engineers While a significant amount of television air time is dedicated to dramatizing careers, engineering careers seem somewhat vacant from the prime time line up. Many studies have been conducted to look at the impact of popular television shows on how people view career professionals but little has been done to look at the impact of popular media on people’s views of engineers. This pilot study looked at the impact of viewing popular media articles that focus on engineering characters on a person’s perception of an engineer. The study focused on using three popular media articles (Dilbert, Mythbusters, and The Big Bang Theory) as representations of engineers. Participants for this study were graduate students at a large research university. Utilizing individual interviews, participants in this study were asked to describe their initial mental picture of an engineer from their own personal experiences. Participants were shown a series of media articles and were asked to describe the mental picture of an engineer they held after watching the media articles.

  • Dilbert E a Tradução Para Dublagem
    63 DILBERT E A TRADUÇÃO PARA DUBLAGEM Turma de Tradução Avançada1 RESUMO Traduzir não é uma tarefa fácil. O tradutor tem de passar por várias etapas a fim de terminar o projeto no qual esteja trabalhando. Por isso, o Professor Mestre José Manuel da Silva desenvolveu uma tarefa que visou simular a rotina de uma empresa de tradução, editora ou de um estúdio cinematográfico, a fim de trabalhar prazo, estresse, gerenciamento de equipe e distribuição de tarefas entre os alunos da disciplina de Tradução Avançada, do Instituto Superior Anísio Teixeira (ISAT). Para que essa meta fosse alcançada, a turma traduziu o primeiro episódio da primeira temporada da série animada de televisão Dilbert, que teve duas temporadas e foi exibida entre 1999 e 2000, baseada na história em quadrinhos homônima criada por Scott Adams. Este trabalho tem como objetivo relatar passo a passo as etapas pelas quais os alunos da disciplina de Tradução Avançada tiveram de passar, tais como a divisão de grupos, a confecção do script com a transcrição do áudio, a tradução propriamente dita, a revisão e os relatórios a serem enviados para o professor. PALAVRAS-CHAVE: tradução. tradução para dublagem. Dilbert. ABSTRACT Translating is not an easy endeavor. The translator has to go through several steps in order to finish the project at hand. Therefore, Professor José Manuel da Silva, M. A., assigned a task that aimed at simulating the routine of a translation firm, publisher or a cinematographic studio in order to work with deadlines, stress, team management and task distribution among the students of the Advanced Translation course at the Instituto Superior Anísio Teixeira (ISAT).

  • Topic Notes: Protection and Security
    Computer Science 330 Operating Systems Siena College Fall 2020 Topic Notes: Protection and Security The operating system is (in part) responsible for protection – to ensure that each object (hardware or software) is accessed correctly and only by those processes that are allowed to access it. We have seen protection in a few contexts: • memory protection • file protection • CPU protection We want to protect against both malicious and unintentional problems. Protection Domains There are a number of ways that an OS might organize the access rights for its protection system. A domain is a set of access rights and the objects (devices, files, etc.) they refer to. An abstract example from another text (Tanenbaum): This just means that processes executing in, for example, domain 1, can read file1 and can read and write file2. The standard Unix protection system can be viewed this way. A process’ domain is defined by its user id (UID) and group id (GID). Files (and devices, as devices in Unix are typically accessed through special files) have permissions for: user, group, and other. Each can have read, write, and/or execute permission. A process begins with the UID and GID of the process that created it, but can set its UID and GID during execution. Whether a process is allowed a certain type of access to a certain file is determined by the UID and GID of the process, and the file ownership and permissions. The superuser (UID=0) has the ability to set processes to any UID/GID. Regular users usually rely on setuid and setgid programs in the filesystem to change UID/GID.
