R – your tool for data analysis

R‬ is a language and environment for Statistical Computing and Graphics. R provides a free/open source, cross­-platform, object-oriented environment to perform data analysis and visualisation tasks. Strength of R lies in its vibrant community, robust package repository and strong graphics capabilities. ‪

R provides all necessary tools required for various stages of a data analysis project. It provides techniques for data acquisition and processing as well as for data analysis and visualisation. It ranges from accessing data in various formats (CSV, XML…) to all possible ways of data manipulation (tabulation, aggregation…)to rich support for graphics (histogram, box plot etc.) to statistical models (regression, ANOVA…).

It is not always necessary to use built-in and supported functions and packages. Depending on the requirements, one can also develop his/her own functions, scripts and packages.

Recently, CDAC Mumbai has announced a 3-day course on R entitled “Using R for Data Visualisation and Analytics”. This course is aimed to cover in detail the features of R related to data analysis and visualisation. More details can be accessed here.

CDAC Mumbai projects awarded SKOCH Order of Merit Medals and listed among India’s Best-2013

Three research projects of CDAC Mumbai have been awarded the prestigious SKOCH Order of Merit medals for their distinguished and outstanding contributions in enabling and promoting Digital Inclusion of Indian citizens into the ICT mainstream. These projects are:

These medals along with certificates were conferred to CDAC Mumbai in an awards ceremony held at 33rd SKOCH Summit during September 2-3, 2013 in New Delhi. SKOCH awards from SKOCH Group are hailed as one of the highest independently instituted civilian honours in the country and considered as independent benchmarks for best practices in India in the fields of governance, finance, banking, technology, corporate citizenship, economics and inclusive growth.

CDAC Mumbai projects were selected by an eminent jury of domain experts among nearly a thousands nominations through a rigorous scrutiny process. Scrutiny process went for nearly 3 months comprising about 200 jury presentations and 150 hours of deliberations.

These research projects have also been listed among India’s Best-2013 in Smart Governance and Digital Inclusion. It is noteworthy here that CDAC Mumbai, over 25 years, has been extensively involved in R & D activities related to various fields of software technology such as multilingual computing, e-learning, e-governance, free/open source software & cyber security etc. Solutions developed under these projects are being used by a large number of targeted end-users, community members, institutions etc. and have been highly appreciated by them.

As significant section of Indian population consists of people with disabilities, “Enhancing Accessibility for FOSS Desktops project is an effort to make common computer desktop accessible to such people, thereby enabling them to avail the benefits of modern ICT technologies. This project so far has been able to produce reusable and accessible software solutions as per the specific needs of disabled people having visual, physical and cognitive impairments. All solutions and products developed under the project are open source and freely available. All these solutions have been widely deployed, distributed and downloaded among individuals and disability related organisations/institutions. These can be accessed at http://www.cdacmumbai.in/accessibility.

Major products developed under the project are ALViC (Accessible Linux for Visually Challenged), Anumaan (an predictive text entry system) and GEM (GEstures with Mouse) for physically impaired people, GNU/Linux distribution for Cognitively Challenged etc. Moreover, project has also made significant contributions to FOSS communities like Orca, Nautilus, Poppler, and OpenOffice.org etc.

On the other hand, Online Labs (Olabs) for school lab experiments provides students with the ease and convenience of conducting experiments over the Internet. It has been developed to supplement the traditional physical labs and bridge the constraints of time and geographical distances. This not only reduces the costs incurred for conducting experiments in real time, but also gives a student the flexibility to explore and repeat experiments till they are thorough.

At present, 30 Physics and Chemistry experiments covering topics like Hooke’s Law, Reflection in concave Mirror, Boiling Point of Water, etc are available for online access. Each experiment has sections covering related theory, procedure, animation, simulation, assessment and reference material. It can be accessed at http://www.olabs.co.in.

While, Parikshak, an Online Automated Computer Program Grading & Analysis Tool, aims at improving the quality of computer programmers in India, by exploiting automated systems for programming assessment and teaching. CDAC Mumbai has successfully demonstrated the effectiveness of this tool in its decade old Post Graduate Diploma courses in Software Technology, by providing better computer programmers to the Indian Software Industry.

The tool is now available for use online at www.parikshak.in and has been adopted by distinguished educational and corporate organisations in India.

One-day workshop on Parikshak — an online program grading system organised by CDAC, Mumbai

Computer Programming is an important aspect of any computer-science/information-technology course. This is among the most difficult to teach, since being a good programmer is a skill to be acquired coupled with knowledge of many different aspects such as abstraction, analysis, structured programming, debugging, etc. Usually computer programming is taught through a combination of theory classes on concepts and languages, and lab classes on specific languages. Assignments are given, which are manually graded by the instructor. Manual grading of programs is very tedious and time consuming. While evaluating student assignments the teacher has to act as a compiler/interpreter and inspect each line in program and judge whether the overall program would work correctly. While this grading approach works fine for a small number of simple assignments, it gets unwieldy as the complexity and number of the assignment increases. This, in turn, results in inadequate attention to the practical programming skills of students.

Parikshak is a web based system which offers a solution to this. A tool like Parikshak, which facilitates automated evaluation of software programs can significantly reduce the load of the faculty, give direct feedback to student, thereby leading to efficient handling of programming assignments/exams. Parikshak allows teachers to define programming assignments systematically, allows registered students to attempt solving them online, and automatically assesses the solution. The feedback is available to the students and the faculty, for follow up and record. Using Parikshak to manage your programming component, clearly offers many advantages.

During the workshop, we will demonstrate the system, discussing various ways in which tool can be used in the academic setting, and provide hands-on for faculty. Since we have limited number of seats, we request you to confirm participation from your colleges latest by June 12, 2013, by email or phone call. Teachers from the CS/IT departments are preferred, though others with some programming experience/interest are welcome.

National Workshop on FOSS Desktop Accessibility on August 26, 2011 at CDAC, Kharghar, Navi Mumbai

In today’s world, the use of information and communication technologies (ICT) is growing day by day. We use these technologies very extensively in fulfilling our routine tasks like bill payments, banking transactions, reservations and many more to the extent that ICT is not a luxury, but necessity today. A large section of the society comprising people with disabilities finds it difficult to use ICT in the same way as normal people do. This includes the visually impaired (fully or partially blind), hearing impaired, people with cognitive disabilities (memory loss, etc.) and cerebral problems etc..

Such people have to be provided with different kinds of assistive technologies either software-based or hardware-based to make ICT accessible to them. A large number of software-based assistive technologies are normally in the form of applications running on desktops which make common desktop applications (office applications, browser etc.) accessible for the disabled person. Free & Open Source Software (FOSS) tools/techniques play an important role in creating assistive technologies that are free-of-cost, available to all, easily maintainable etc. for a large portion of population in a country like India.

The workshop intends to provide a platform for promotion and adoption of FOSS in the area of accessibility as well as creating opportunities for all stakeholders to discuss and identify the areas of accessibility that are still untouched. The workshop will host keynote and invited lectures by distinguished personalities of the field.

This workshop is being organized by CDAC, Mumbai at their Kharghar, Navi Mumbai campus. More details about the workshop can be accessed at http://www.cdacmumbai.in/index.php/news_and_events/national_workshop_on_foss_desktop_accessibility

National Workshop on FOSS Adoption in Education on August 27, 2011 at CDAC, Kharghar, Navi Mumbai

Many softwares have been developed for adopting technology in education for resource availability, sharing, and access to them even after school/college hours. There have also been developments aimed to ease other educational activities like course enrollment, conduct of examination from setting question papers to correcting answers and displaying results. Such softwares are available in the market in both forms proprietary and open source.

Unlike the proprietary softwares, Free and Open Source Software (FOSS) alternatives are free of cost, source code is available with the software, and the institution has freedom to modify the source code to customize the software as per requirement. For modification and maintenance the institution has full freedom to develop the required skills in-house with the help of faculties and system admin staff or they can choose to hire external help.

However, one of the problems is there are many FOSS tools available and a novice institution/teacher/software development organization has to take lot of efforts to short-list/choose a software for adoption. They will have to spend days looking for different softwares, their reviews, comparisons, etc. If such problems are reduced for the ease of FOSS adoption then the institutions/teachers can reap the above benefits of FOSS much more seamlessly.

The workshop intents to promote technology and FOSS adoption in educational institutions. Various FOSS tools in education will be demonstrated in the workshop. The participants will also get to experience the work of C-DAC Mumbai in promoting technology/FOSS in education. The workshop will provide an opportunity to interact with participants from different organizations and industry practitioners. The workshop will involve keynote and invited lectures by distinguished researchers and/or professionals.

This workshop is being organized by CDAC, Mumbai at their Kharghar, Navi Mumbai campus. More Details about the workshop can be accessed at http://www.cdacmumbai.in/index.php/news_and_events/national_workshop_on_foss_adoption_in_education
