Azara: A New 32 bit RepRap with Improved Performance

A. Guerrero-de-Mier, M.M. Espinosa, M. Domínguez
2015 Procedia Engineering  
RepRap printers' firmware is based on 8 bits microcomputers, and an external computer is needed to process 3D models and send it to printers (by USB or SD card).  ...  We have built a RepRap variant (RepRap Azara) that doesn´t need external computer, using a 32 bit ARM microcomputer (Beaglebone) and developing software and firmware able to process 3D models and to communicate  ...  This initiative has achieved to design and build many 3D printers, published under the "Do It Yourself" philosophy.  ...

Situational awareness: Personalizing issue tracking systems

Olga Baysal, Reid Holmes, Michael W. Godfrey
2013 2013 35th International Conference on Software Engineering (ICSE)  
Issue tracking systems play a central role in ongoing software development; they are used by developers to support collaborative bug fixing and the implementation of new features, but they are also used  ...  Most such systems are designed around the central metaphor of the "issue" (bug, defect, ticket, feature, etc.), yet increasingly this model seems ill fitted to the practical needs of growing software projects  ...  "He has a query that shows all his open review queue" (P16), "The review queues are very useful, he will check that every few days just to double check he didn't miss an email" (P8).  ...

Advances in internet congestion control

Seungwan Ryu, Christopher Rump, Chunming Qiao
2003 IEEE Communications Surveys and Tutorials  
Finally, we list many open issues that persist in the design, operation, and control of the Internet.  ...  We describe many recently proposed algorithms to combat congestion and improve performance, particularly active queue management (AQM) algorithms such as random early detection (RED) and its variants.  ...  The design principle of TCP is "do not ask the network to do what you can do yourself" [42] .  ...

Activate this classroom at time now

Manuel D. Rossetti
1997 Proceedings of the 29th conference on Winter simulation - WSC '97  
These techniques recognize that the passive model of the typical college lecture does not work for many students.  ...  Instead, active and cooperative learning focuses on the premise that students learn best by doing and working with each other.  ...  In addition you have the information contained in Figure 1 . π 4 = 1− x 2 0 1 ∫ dx 1 1 0 Figure 1 Do not use books as a reference; however, do use your class notes.  ...

Fungi and Incompatibility in Fungi

1966 Nature  
The theory is so highly developed that its sophistication has far outstripped its usefulness.  ...  This is surprising, if one remembers that queueing serves as a model for telephone traffic, breakdown repair, aircraft stacks, flight reservation, and many other situations in addition to the more obvious  ...

Irrationality and Cognition [chapter]

John L. Pollock
2008 Epistemology  
A consequence of this account is that a theory of rationality is a descriptive theory, describing contingent features of a cognitive architecture, and it forms the core of a general theory of "voluntary  ...  It can be perfectly rational for a reflexive cognizer to break these rules.  ...  Just why is it irrational to avoid thinking about possible problems for our theory? It is practical cognition that allows us to do this.  ...

Nan-Chen Chen, Sarah Poon, Lavanya Ramakrishnan, Cecilia R. Aragon
2016 Proceedings of the 19th ACM Conference on Computer-Supported Cooperative Work & Social Computing - CSCW '16  
Time as a metaphor is so pervasive in the discussions and valuation of computing within the HPC community that it is worthy of close study.  ...  generation of supercomputers is expected to utilize radically different computational paradigms, necessitating fundamental changes in how the community of scientific users will make the most efficient use  ...  Collaborations use models that encapsulate the physics of natural systems. This process is called simulation.  ...

Networks: A [chapter]

Jean Walrand
2021 Probability in Electrical Engineering and Computer Science  
We explain some key results about queueing networks.Section 5.1 explores a model of how rumors spread in a social network. Epidemiologists use similar models to study the spread of viruses.  ...  We explore models of such propagations. The technology behind social networks is the internet where packets travel from queue to queue.  ...  To explore this question, let us go back to our model where each node listens only to its left-neighbor with probability p.  ...
