    - - -

    Perry Greenfield -

    - - - -

    Talk/Paper Abstract

    - - -

    I will talk about how Python was used to solve our problems for -the Hubble Space Telescope. From humble beginnings as a glue -element for our legacy software, it has become a cornerstone of -our scientific software for HST and the next large space -telescope, the James Webb Space Telescope, as well as many other -astronomy projects. The talk will also cover some of the history -of essential elements for scientific Python and where future -work is needed, and why Python is so well suited for scientific -software. -

    IPython : Beyond the Simple Shell

    - - -

    Fernando Perez -

    - - - -

    Talk/Paper Abstract

    - - -

    IPython is a widely used system for interactive computing in -Python that extends the capabilities of the Python shell with -operating system access, powerful object introspection, -customizable "magic" commands and many more features. It also -contains a set of tools to control parallel computations via -high-level interfaces that can be used either interactively or -in long-running batch mode. In this talk I will outline some of -the main features of IPython as it has been widely adopted by -the scientific Python user base, and will then focus on recent -developments. Using the high performance ZeroMQ networking -library, we have recently restructured IPython to decouple the -kernel executing user code from the control interface. This -allows us to expose multiple clients with different -capabilities, including a terminal-based one, a rich Qt client -and a web-based one with full matplotlib support. In conjunction -with the new HTML5 matplotlib backend, this architecture opens -the door for a rich web-based environment for interactive, -collaborative and parallel computing. There is much interesting -development to be done on this front, and I hope to encourage -participants at the sprints during the conference to join this -effort. -

    matplotlib: Beyond the simple plot

    - - -

    John Hunter -

    - - - -

    Talk/Paper Abstract

    - - -

    matplotlib, a python package for making sophisticated -publication quality 2D graphics, and some 3D, has long supported -a wide variety of basic plotting types such line graphs, bar -charts, images, spectral plots, and more. In this talk, we will -look at some of the new features and performance enhancements in -matplotlib as well as some of the comparatively undiscovered -features such as interacting with your data and graphics, and -animating plot elements with the new animations API. We will -explore the performance with large datasets utilizing the new -path simplification algorithm, and discuss areas where -performance improvements are still needed. Finally, we will -demonstrate the new HTML5 backend, which in combination with the -new HTML5 IPython front-end under development, will enable an -interactive Python shell with interactive graphics in a web -browser. -

    Mayavi : Bringing Data to Life

    - - -

    Prabhu Ramachandran -

    - - - -

    Talk/Paper Abstract

    - - -

    Mayavi is a powerful 3D plotting package implemented in -Python. It includes both a standalone user interface along with -a powerful yet simple scripting interface. The key feature of -Mayavi though is that it allows a Python user to rapidly -visualize data in the form of NumPy arrays. Apart from these -basic features, Mayavi has some advanced features. These -include, automatic script recording, embedding into a custom -user dialog and application. Mayavi can also be run in an -offscreen mode and be embedded in a sage notebook -(http://www.sagemath.org). We will first rapidly demonstrate -these key features of Mayavi. We will then discuss some of the -underlying technologies like enthought.traits, traitsUI and TVTK -that form the basis of Mayavi. The objective of this is to -demonstrate the wide range of capabilities that both Mayavi and -its underlying technologies provide the Python programmer. -

    Nipype: Opensource platform for unified and replicable interaction with existing neuroimaging tools

    - - -

    Satrajit Ghosh -

    - - - -

    Talk/Paper Abstract

    - - -

    Current neuroimaging software offer users an incredible -opportunity to analyze their data in different ways, with -different underlying assumptions. However, this has resulted in -a heterogeneous collection of specialized applications without -transparent interoperability or a uniform operating -interface. Nipype, an open-source, community-developed -initiative under the umbrella of Nipy, is a Python project that -solves these issues by providing a uniform interface to existing -neuroimaging software and by facilitating interaction between -these packages within a single workflow. Nipype provides an -environment that encourages interactive exploration of -neuroimaging algorithms from different packages, eases the -design of workflows within and between packages, and reduces the -learning curve necessary to use different packages. Nipype is -creating a collaborative platform for neuroimaging software -development in a high-level language and addressing limitations -of existing pipeline systems. -

    Talk/Paper Abstract

    - - -

    In May of 2005, I started a pilgrimage to transform myself into -a doctor of engineering. Little did I know, then, that my -journey would bring me in touch with some of the most creative, -vibrant and inspiring minds in the open source world, and that -an opportunity would arise to help realise their (and now my) -dream: a completely free and open environment for performing -cutting edge science. In this talk, I take you on my journey, -and along the way introduce the NumPy and SciPy projects, our -community, the early days of packaging, our documentation -project, the publication of conference proceedings as well as -work-shops and sprints around the world. I may even tell you a -bit about my PhD on super-resolution imaging! -

    Building an open development community for neuroimaging analysis

    - - -

    Jarrod Millman -

    - - - -

    Talk/Paper Abstract

    - - -

    Programming is becoming increasingly important to scientific activity. As its -importance grows, the need for better software tools becomes more and more -central to scientific practice. However, many fields of science rely on -badly written, poorly documented, and insufficiently tested codebases. -Moreover, scientific software packages often implement only the approaches -and algorithms needed or promoted by the specific lab where the software -was written.

    - -

    In this talk, I will illustrate this situation by discussing some of the -weaknesses of the software ecosystem for neuroimaging analysis circa 2004. -I will then describe how several of my colleagues and I are attempting -to rectify this situation with a project called Neuroimaging in Python -(http://nipy.org). Specifically, I will discuss the approach we've taken -(e.g., using Python) and the lessons we've learned. -

    Python as a Platform for Scientific Computing Literacy for 10+2 Students: Weighing the Balance

    - - -

    Farhat Habib -

    - - - -

    Talk/Paper Abstract

    - - -

    The use of Python as a language for introducing computing is -becoming increasingly widespread. Here we report out findings -from two years of running an introduction to computing course -with Python as the programming language, and building upon it, -using SciPy as a scientific computing language in a course on -scientific computing. -

    - -

    -The course is designed as a general computing course for -introducing computing to first year undergraduate students of -science. We find that a large majority of our incoming students -have no prior exposure to programming and none of the students -had any exposure to Python. Thus, the design of the course is -such that it allows everybody to be brought up to speed with -general programming concepts. Later, the students will later -specialize in varied topics from Biology to pure Mathematics, -thus, the course emphasizes general computing concepts over -specialized techniques. At a second course in Scien- tific -Computing numerical methods are introduced with the aid of -Scipy. The introduction to computing course has been taught -twice in Fall 2009 and 2010 to batches of around 100 students -each. In this paper we report our experience with teaching -Python and student and faculty feedback related to the course. -

    Usb Connectivity Using Python

    - - -

    Arun C. H. -

    - - - -

    Talk/Paper Abstract

    - - -

    Host software using Python interpreter language to communicate -with the USB Mass Storage class device is developed and -tested. The usic18F4550.pyd module encapsulating all the -functions needed to configure USB is developed. The Python -extension .pyd using C/C++ functions compatible for Windows make -use of SWIG, distutils and MinGW. SWIG gives the flexibility to -access lower level C/C++ code through more convenient and higher -level languages such as Python, Java, etc. Simplified Wrapper and -Interface Generator (SWIG) is a middle interface between Python -and C/C++. The purpose of the Python interface is to allow the -user to initialize and configure USB through a convenient -scripting layer. The module is built around libusb which can -control an USB device with just a few lines. Libusb-win32 is a -port of the USB library to the Windows operating system. The -library allows user space applications to access any USB device on -Windows in a generic way without writing any line of kernel driver -code. A simple data acquisition system for measuring analog -voltage, setting and reading the status of a particular pin of the -micro controller is fabricated. It is interfaced to PC using USB -port that confirms to library USB win32 device. The USB DAQ -hardware consists of a PIC18F4550 micro-controller and the -essential components needed for USB configuration. -

    Automation of an Optical Spectrometer

    - - -

    Arun C. H. -

    - - - -

    Talk/Paper Abstract

    - - -

    This paper describes the automation performed for an Optical -Spectrometer in order to precisely monitor angles, change -dispersing angle and hence measure wave length of light using a -data logger, necessary hardware and Python. Automating instruments -through programs provides great deal of power, flexibility and -precision. Optical Spectrometers are devices which analyze the -wave length of light, and are typically used to identify -materials, and study their optical properties. A broad spectrum of -light is dispersed using a grating and the dispersed light is -measured using a photo transistor. The signal is processed and -acquired using a data logger. Transfer of data, changing angle of -diffraction are all done using the Python. The angle of -diffraction is varied by rotating the detector to pick up lines -using a stepper motor. The Stepper motor has 180 steps or 2 -degrees per step. A resolution of 0.1 degree is achieved in the -spectrometer by using the proper gear ratio. The data logger is -interfaced to the computer through a serial port. The stepper -motor is also interfaced to the computer through another serial -port. Python is chosen here for its succinct notation and is -implemented in a Linux environment. -

    Wavelet based denoising of ECG using Python

    - - -

    Hrishikesh Deshpande -

    - - - -

    Talk/Paper Abstract

    - - -

    The python module "RemNoise" is presented. It allows user to -automatically denoise one-dimensional signal using wavelet -transform. It also removes baseline wandering and motion -artifacts. While RemNoise is developed primarily for biological -signals like ECG, its design is generic enough that it should be -useful to applications involving one-dimensional signals. The -basic idea behind this work is to use multi-resolution property of -wavelet transform that allows to study non-stationary signals in -greater depth. Any signal can be decomposed into detail and -approximation coefficients, which can further be decomposed into -higher levels and this approach can be used to analyze the signal -in time-frequency domain. The very first step in any -data-processing application is to pre-process the data to make it -noise-free. Removing noise using wavelet transform involves -transforming the dataset into wavelet domain, zero out all -transform coefficients using suitable thresholding method and -reconstruct the data by taking its inverse wavelet transform. This -module makes use of PyWavelets, Numpy and Matplotlib libraries in -Python, and involves thresholding wavelet coefficients of the data -using one of the several thresholding methods. It also allows -multiplicative threshold rescaling to take into consideration -detail coefficients in each level of wavelet decomposition. The -user can select wavelet family and level of decompositions as -required. To evaluate the module, we experimented with several -complex one-dimensional signals and compared the results with -equivalent procedures in MATLAB. The results showed that RemNoise -is excellent module to preprocess data for noise-removal. -

    HyPy & HydroPic: Using python to analyze hydrographic survey data

    - - -

    Dharhas Pothina -

    - - - -

    Talk/Paper Abstract

    - - - -

    -The Texas Water Development Board(TWDB) collects hydrographic -survey data in lakes, rivers and estuaries. The data collected -includes single, dual and tri-frequency echo sounder data -collected in conjunction with survey grade GPS systems. This raw -data is processed to develop accurate representations of -bathymetry and sedimentation in the water bodies surveyed. -

    -

    -This talk provides an overview of how the Texas Water Development -Board (TWDB) is using python to streamline and automate the -process of converting raw hydrographic survey data to finished -products that can then be used in other engineering applications -such as hydrodynamic models, determining lake -elevation-area-capacity relationships and sediment contour maps, -etc. -

    -

    -The first part of this talk will present HyPy, a python module -(i.e. function library) for hydrographic survey data -analysis. This module contains functions to read in data from -several brands of depth sounders, conduct anisotropic -interpolations along river channels, apply tidal and elevation -corrections, apply corrections to boat path due to loss of GPS -signals as well as a variety of convenience functions for dealing -with spatial data. -

    -

    -In the second part of the talk we present HydroPic, a simple -Traits based application built of top of HyPy. HydroPic is -designed to semi-automate the determination of sediment volume in -a lake. Current techniques require the visual inspection of images -of echo sounder returns along each individual profile. We show -that this current methodology is slow and subject to high human -variability. We present a new technique that uses computer vision -edge detection algorithms available in python to semi-automate -this process. HydroPic wraps these algorithms into a easy to use -interface that allows efficient processing of data for an entire -lake. -

    Parallel Computation of Axisymmetric Jets

    - - -

    Nek Sharan -

    - - - -

    Talk/Paper Abstract

    - - -

    Flow field for imperfectly expanded jet has been simulated using -Python for prediction of jet screech frequency. This plays an -important role in the design of advanced aircraft engine nozzle, -since screech could cause sonic fatigue failure. For computation, -unsteady axisymmetric Navier-Stokes equation is solved using fifth -order Weighted Essentially Non-Oscillatory (WENO) scheme with a -subgrid scale Large-Eddy Simulation (LES) model. Smagorinsky’s -eddy viscosity model is used for subgrid scale modeling with -second order (Total Variation Diminishing) TVD Runge Kutta time -stepping. The performance of Python code is enhanced by using -different Cython constructs like declaration of variables and -numpy arrays, switching off bound check and wrap around etc. Speed -up obtained from these methods have been individually clocked and -compared with the Python code as well as an existing in-house C -code. Profiling was used to highlight and eliminate the expensive -sections of the code. -

    -

    -Further, both shared and distributed memory architectures have -been employed for parallelization. Shared memory parallel -processing is implemented through a thread based model by manual -release of Global Interpreter Lock (GIL). GIL ensures safe and -exclusive access of Python interpreter internals to running -thread. Hence while one thread is running with GIL the other -threads are put on hold until the running thread ends or is forced -to wait. Therefore to run two threads simultaneously, GIL was -manually released using "with nogil" statement. The relative -independence of radial and axial spatial derivative computation -provides an option of putting them in parallel threads. On the -other hand, distributed memory parallel processing is through MPI -based domain decomposition, where the domain is split radially -with an interface of three grid points. Each sub-domain is -delegated to a different processor and communication, in the form -of message transmission, ensures update of interface grid -points. Performance analyses with increase in number of processors -indicate a trade-off between computation and communication. A -combined thread and MPI based model is attempted to harness the -benefits from both forms of architectures. -

    Simplified and effective Network Simulation using ns-3

    - - -

    Erroju Rama Krishna -

    - - - -

    Talk/Paper Abstract

    - - - -

    -Network simulation has great significance in the research areas of -modern networks. The ns-2 is the popular simulation tool which -proved this, in the successive path of ns-2 by maintaining the -efficiency of the existing mechanism it has been explored with a -new face and enhanced power of python scripting in ns-3. Python -scripting can be added to legacy projects just as well as new -ones, so developers don't have to abandon their old C/C++ code -libraries, but in the ns-2 it is not possible to run a simulation -purely from C++ (i.e., as a main() program without any OTcl), ns-3 -does have new capabilities (such as handling multiple interfaces -on nodes correctly, use of IP addressing and more alignment with -Internet protocols and designs, more detailed 802.11 models, etc.) -

    -

    -In ns-3, the simulator is written entirely in C++, with optional -Python bindings. Simulation scripts can therefore be written in -C++ or in Python. The results of some simulations can be -visualized by nam, but new animators are under development. Since -ns-3 generates pcap packet trace files, other utilities can be -used to analyze traces as well. -

    -

    -In this paper the efficiency and effectiveness of IP addressing -simulation model of ns-3 is compared with the ns-2 simulation -model,ns-3 model consisting of the scripts written in Python which -makes the modeling simpler and effective -

    Talk/Paper Abstract

    - - -

    The primary objective is defining a centralized testing -environment and a model of testing framework which integrates all -projects in testing in a single unit. -

    -

    -The implementation of concurrent processing systems and adopting -client server architecture and with partitioned server zones for -environment manipulation, allows the server to run test requests -from different projects with different environment and testing -requests. The implementation provides features of auto-test -generation, scheduled job run from server, thin and thick clients. -

    - -

    -The core engine facilitates the management of tests from all the -clients with priority and remote scheduling. It has an extended -configuration utility to manipulate test parameters and watch -dynamic changes. It not only acts as a request pre-preprocessor -but also a sophisticated test bed by its implementation. It is -provided with storage and manipulation segment for every -registered project in the server zone. The system schedules and -records events and user activities thereby the results can be -drilled and examined to core code level with activates and system -states at the test event point. -

    -

    -The system generates test cases both in human readable as well as -executable system formats. The generated tests are based on a -pre-defined logic in the system which can be extended to adopt new -cases based on user requests. These are facilitated by a template -system which has a predefined set of cases for various test types -like compatibility, load, performance, code coverage, dependency -and compliance testing. It is also extended with capabilities like -centralized directory systems for user management with roles and -privileges for authentication and authorization, global mailer -utilities, Result consolidator and Visualizer. -

    -

    -With the effective implementation of the system with its minimal -requirements, the entire testing procedure can be automated with -the testers being effectively used for configuring, ideating and -managing the test system and scenarios. The overhead of managing -the test procedures like environment pre-processing, test -execution, results collection and presentation are completely -evaded from the testing life cycle. -

    A system for distance learning in the field of Physics and -Electricity has been used for three years with some success for 15 -years old students. The students are given a little case -containing a PHOENIX box (see -http://www.iuac.res.in/~elab/phoenix/) featuring electric analog -and digital I/O interfaces, some unexpensive discrete components -and a live (bootable) USB stick. -

    -

    -The PHOENIX project was started by Inter University Accelerator -Centre in New Delhi, with the objective of improving the -laboratory facilities at Indian Universities, and growing with the -support of the user community. PHOENIX depends heavily on Python -language. The data acquisition, analysis and writing simulation -programs to teach science and computation. -

    -

    -The hardware design of PHOENIX box is freely available. -

    -

    -The live bootable stick provides a free/libre operating system, -and a few dozens educational applications, including applications -developed with Scipy to drive the PHOENIX box and manage the -acquired measurements. The user interface has been made as -intuitive as possible: the main window shows a photo of the front -face of the PHOENIX acquisition device, its connections behaving -like widgets to express their states, and a subwindow displays in -real time the signals connected to it.

    Talk/Paper Abstract

    - - -

    Electronics in industrial has been passing through revolution due -to extensive use of Microcontroller. These electronic devices are -having a high capability to handle multiple events. Their -capability to communicate with the computers has made the -revolution possible. Therefore it is very important to have -trained Personnel in Microcontroller. In the present work -experiments for study of Microcontrollers and its peripherals with -Simulation using Python is carried out. This facilitates the -teachers to demonstrate the experiments in the classroom sessions -using simulations. Then the same experiments can be carried out in -the labs (using the same simulation setup) and the microcontroller -hardware to visualize and understand the experiments. Python is -selected due to its versatility and also to promote the use of -open source software in the education. -

    -

    -Here we demonstrate the experiment of driving seven segment -displays by microcontroller. Four seven segment displays are -interfaced with the microcontroller through a single BCD to seven -segments Display Decoder/Driver (74LS47) and switching -transistors. The microcontroller switches on the first transistor -connected to the first display and puts the number to be displayed -on 74LS47. Then it pause a while, switches off the first display -and puts the number to be displayed on the second display and -switches it on. A similar action is carried out for all the -display and the cycle is repeated again and again. Now we can -control the microcontroller action using the serial port of the -computer through python. Simulating the seven segment display -using VPYTHON module and communicating the same action to the -microcontroller, we can demonstrate the switching action of the -display at a very slow rate. It is possible to actually see each -display glowing individually one after another. Now we can -gradually increase the rate of switching the display. You see each -display glowing for a few milliseconds. Finally the refresh rate -is taken very high to around more than 25 times a second we see -that all the display glowing simultaneously. -

    -

    -Hence it is possible to simulate and demonstrate experiments and -understand the capabilities of the microcontroller with a lot of -ease and at a very low cost. -

    Talk/Paper Abstract

    - - -

    The idea is to demonstrate the PyProt (Python Proteomics), an -approach to classify mass spectrometry data and efficient use of -statistical methods to look for the potential prevalent disease -markers and proteomic pattern diagnostics. Serum proteomic pattern -diagnostics can be used to differentiate samples from the patients -with and without disease. Profile patterns are generated using -surface-enhanced laser desorption and ionization (SELDI) protein -mass spectrometry. This technology has the potential to improve -clinical diagnostic tests for cancer pathologies. There are two -datasets used in this study which are taken from the FDA-NCI -Clinical Proteomics Program Databank. First data is of ovarian -cancer and second is of Premalignant Pancreatic Cancer .The Pyprot -uses the high-resolution ovarian cancer data set that was -generated using the WCX2 protein array. The ovarian cancer dataset -includes 95 controls and 121 ovarian cancer sets, where as -pancreatic cancer dataset has 101 controls and 80 pancreatic -cancer sets. There are two modules designed and implemented in -python using Numpy , Scipy and Matplotlib. There are two different -kinds of classifications implemented here, first to classify the -ovarian cancer data set. Second type focuses on randomly -commingled study set of murine sera. it explores the ability of -the low molecular weight information archive to classify and -discriminate premalignant pancreatic cancer compared to the -control animals. -

    -

    -A crucial issue for classification is feature selection which -selects the relevant features in order to focus the learning -search. A relaxed setting for feature selection is known as -feature ranking, which ranks the features with respect to their -relevance. Pyprot comprises of two modules; First includes -implementation of feature ranking in Python using fisher ratio and -t square statistical test to avoid large feature space. In second -module, Multilayer perceptron (MLP) feed forward neural network -model with static back propagation algorithm is used to classify -.The results are excellent and matched with databank results and -concludes that PyProt is useful tool for proteomic finger -printing. -

    A Parallel 3D Flow Solver in Python Based on Vortex Methods

    - - -

    Prashant Agrawal -

    - - - -

    Talk/Paper Abstract

    - - -

    A 3D flow solver for incompressible flow around arbitrary 3D -bodies is developed. The solver is based on vortex methods whose -grid-free nature makes it very general. It uses vortex particles -to represent the flow-field. Vortex particles (or blobs) are -released from the boundary, and these advect, stretch and diffuse -according to the Navier-Stokes equations. -

    -

    -The solver is based on a generic and extensible design. This has -been made possible mainly by following a universal theme of using -blobs in every component of the solver. Advection of the -particles is implemented using a parallel fast multipole -method. Diffusion is simulated using the Vorticity Redistribution -Technique (VRT). To control the number of blobs, merging of nearby -blobs is also performed. -

    -

    -Each component of the solver is parallelized. The boundary, -advection and stretching algorithms are based on the same parallel -velocity algorithm. Domain decomposition for parallel velocity -calculator is performed using Space Filling Curves. Diffusion, -which requires knowledge of each particle's neighbours, uses a -parallelized fast neighbour finder which is based on a bin data -structure. The same neighbour finder is used in merging also. -

    -

    -The code is written completely in Python. It is well-documented -and well-tested. The code base is around 4500 lines long. The -design follows an object oriented approach which makes it -extensible enough to add new features and alternate algorithms to -perform specific tasks. -

    -

    -The solver is also designed to run in a parallel environment -involving multiple processors. This parallel implementation is -written using mpi4py, an MPI implementation in Python. -

    -

    -Rigorous testing is performed using Python's unittest module. Some -standard example cases are also solved using the present solver. -

    -

    -In this talk we will outline the overall design of the solver and -the algorithms used. We discuss the benefits of Python and also -some of the current limitations with respect to parallel testing. -

    Performance Evaluation of HYBRID MAC for 802.11ad: Next Generation Multi-Gbps Wi-Fi using SimPy

    - - -

    Hemanth Chandran -

    - - - -

    Talk/Paper Abstract

    - - -

    Next generation Wireless Local Area Networks (WLAN) is targeting -at multi giga bits per second throughput by utilizing the -unlicensed spectrum available at 60 GHz, millimeter wavelength -(mmwave).Towards achieving the above goal a new standard namely -the 802.11ad is under consideration. Due to the limited range and -other typical characteristics like high path loss etc., of these -mmwave radios the requirement of the Medium Access Control (MAC) -are totally different. -

    -

    -The conventional MAC protocols tend to achieve different -objectives under different conditions. For example, the (Carrier -Sense Multiple Access / Collision Avoidance) CSMA/CA technique is -robust and simple and works well in overlapping network -scenarios. It is also suitable for bursty type of traffic. On the -other hand CSMA/CA is not suitable for power management since it -needs the stations to be awake always. Moreover it requires an -omni directional antenna pattern for the receiver which is -practically not feasible in 60 GHz band. -

    -

    -A Time Division Multiple Access (TDMA) based MAC is efficient for -Quality of Service (QoS) sensitive traffic. It is also useful for -power saving since the station knows their schedule and can -therefore power down in non scheduled periods. -

    -

    -For 60 GHz usages especially applications like wireless display, -sync and go, and large file transfer, TDMA appears to be a -suitable choice. Whereas for applications that require low latency -channel access (e.g. Internet access etc.)TDMA appears to be -inefficient due to the latency involved in bandwidth reservation. -

    -

    -Another choice is the polling MAC which is highly efficient for -the directional communication in the 60 GHz band. This provides an -improved data rates with directional communication as well as acts -as an interference mitigation scheme. On the contrary polling may -not be efficient for power saving and also not efficient to take -advantage of statistical traffic multiplexing. This technique also -leads to wastage of power due to polling the stations without -traffic to transmit. -

    -

    -Having the above facts in mind and considering the variety of -applications involved in the next generation WLAN systems -operating at 60 GHz, it can be concluded that no individual MAC -scheme can support the traffic requirements. -

    -

    -In this paper we use SimPy to do a Discrete Event Simulation -modeling of a proposed hybrid MAC protocol which dynamically -adjusts the channel times between contention and reservation based -MAC schemes, based on the traffic demand in the network. -

    -

    -We plan to model the problem of admission control and scheduling -using DES using SimPy. SimPy v2.1.0 is being used for the -simulation purposes of the proposed Hybrid MAC. We are new to -using Python for scientific purposes and have just begun using -this powerful tool to get meaningful and useful results. We plan -to share our learning experience and how SimPy is increasingly -becoming a useful tool (apart from regular modeling tools like -Opnet / NS2). -

    PySPH: Smooth Particle Hydrodynamics with Python

    - - -

    pankaj pandey -

    - - - -

    Talk/Paper Abstract

    - - - -

    -We present a python/cython implementation of an SPH framework -called PySPH. SPH (Smooth Particle Hydrodynamics) is a numerical -technique for the solution of the continuum equations of fluid and -solid mechanics. -

    -

    -PySPH was written to be a tool which requires only a basic working -knowledge of python. Although PySPH may be run on distributed -memory machines, no working knowledge of parallelism is required -of the user as the same code may be run either in serial or in -parallel only by proper invocation of the mpirun command. -

    -

    -In PySPH, we follow the message passing paradigm, using the mpi4py -python binding. The performance critical aspects of the SPH -algorithm are optimized with cython which provides the look and -feel of python but the performance near to that of a C/C++ -implementation. -

    -

    -PySPH is divided into three main modules. The base module provides -the data structures for the particles, and algorithms for nearest -neighbor retrieval. The sph module builds on this to describe the -interactions between particles and defines classes to manage this -interaction. These two modules provide the basic functionality as -dictated by the SPH algorithm and of these, a developer would most -likely be working with the sph module to enhance the functionality -of PySPH. The solver module typically manages the simulation being -run. Most of the functions and classes in this module are written -in pure python which makes is relatively easy to write new solvers -based on the provided functionality. -

    -

    -We use PySPH to solve the shock tube problem in gas dynamics and -the classical dam break problem for incompressible fluids. We also -demonstrate how to extend PySPH to solve a problem in solid -mechanics which requires additions to the sph module. -

    Talk/Paper Abstract

    - - -

    The aim of this talk is to get students, specially undergrads -excited about Python. Most of what will be shown, is out there on -the Open web. We just wish to draw attention of the students and -get them excited about Python and possibly image processing and -may be even cognition. We hope that this talk will help retain -more participants for the tutorials and sprint sessions. -

    -

    -The talk will have two parts. The talk will not consist of any -deep research or amazing code. It's a mash-up of some weekend -hacks, if they could be called so. We reiterate that the idea is -not to show the algorithms or the code and ideas. It is, to show -the power that Python gives. -

    -

    -The first part of the talk will deal with the colour Blue. We'll -show some code to illustrate how our eyes suck at blue (1), if -they really do. But, ironically, a statistical analysis that we -did on "Rolling Stones Magazine's Top 500 Songs of All time" (2), -revealed that the occurrences of blue are more than twice the -number of occurrences of red and green! We'll show the code used -to fetch the lyrics and count the occurrences. -

    -

    -The second part of the talk will show some simple hacks with -images. First, a simple script that converts images into ASCII -art. We hacked up a very rudimentary algo to convert images to -ASCII and it works well for "machine generated images." Next, a -sample program that uses OpenCV (3) that can detect faces. We wish -to show OpenCV since it has some really powerful stuff for image -processing. -

    Python has been around for a long enough time now that it needs -serious attention from the educational institutes which teach -computer science. Today Python is known for its simple syntax -yet powerful performance (if not the fastest performance which -is any ways not needed all the time ). From Scientific computing -till graphical user interfaces and from system administration -till web application development, it is used in many -domains. However due to Industrial propaganda leading to -promotion of other interpreted languages (free or proprietary)? -Python has not got the justice in educational sector which it -deserves. This paper will talk on methodologies which can be -adopted to convince the universities for including Python in -their curriculum. The speaker will provide an insight into his -experience on success in getting Python included in some -Universities. A case of SNDT University will be discussed where -the curriculum designers have decided to have Python in their -courses from the next year.
