1.1 Message from AP Vice Director, Prof. Takaya Yamazato
It is my honor to write this message as the APB vice Director. I am proud to be a member of APB covering the Asia Pacific region, the fastest growing region with exciting opportunities. I have been with ComSoc for more than twenty years and have served APB officers of TAC, ISC, and MCC. In the past, I gathered statistics of ICC and Globecom to share among APB members. Although those statistics are not provided anymore, I would like to share some data that I gathered from past ICC2014 held in Sydney. I compare them with the data related to global research and development (R&D) trend. Figure 1 shows the comparisons of R&D spending as a percentage of Gross Domestic Product (GDP). The size of the circle reflects gross expenditure in US billion dollar on R&D. The data are from "2014 Global Funding Forecast" by Battle. What you find is that East Asian countries, as defined by International Monetary Fund (IMF), China, Hong Kong, the Republic of Korea, and Taiwan, become big R&D players together with Singapore. The globalization of R&D endeavors is maturing. The US, EU, Japan, and those Asian countries will dominate global R&D.

The vertical axis of Fig.1 is the number of earned engineering doctoral degrees in 2008 or most recent year until 2012. The data is from "Science and Engineering Indicators 2012" by National Science Board (NSF). China produces large numbers of scientists and engineers. Figure 2 also shows the comparisons of R&D spending as a percentage of GDP. What differs from Fig.1 is that the size of the circle reflects ICC2014 contributors, authors and chairs. Note that I may double counts the numbers. What you find is that almost the same tendency that China produces not only large number of doctors but also ICC (and may also Globecom) papers.
Figure 2
According to the NSF reports I just mentioned, average annual growth in number of researchers in the Asian region outside Japan was generally higher averaged 8%–9% for Taiwan, Singapore, and South Korea, capped by China's 12% annual average. Engineering journal articles growth in the United States and Japan averaged less than 2%; in the EU, about 4.4%. China’s engineering article output grew by close to 16% annually. And the Asia-8 (India, Indonesia, Malaysia, Philippines, Singapore, South Korea, Taiwan, Thailand) economies expanded their combined output of engineering article by 10% a year. In conclusion, the global R&D activity does reflect the number of contributors in ICC or Globecom. And as we see clearly from the figures, Asia-Pacific countries provide a positive impact not only to the global R&D but also to the ComSoc conference activity.

Title: Toward Ubiquitous Massive Accesses in 3GPP Machine-to-Machine Communication Authors: Shao-Yu Lien, Kwang-Cheng Chen, Yonghua Lin Source: IEEE Communications Magazine, vol. 49, no. 4, pp. 66-74, Apr. 2011
Abstract: To enable full mechanical automation where each smart device can play multiple roles among sensor, decision maker, and action executor, it is essential to construct scrupulous connections among all devices. Machine-to-machine communications thus emerge to achieve ubiquitous communications among all devices. With the merit of providing higher-layer connections, scenarios of 3GPP have been regarded as the promising solution facilitating M2M communications, which is being standardized as an emphatic application to be supported by LTE-Advanced. However, distinct features in M2M communications create diverse challenges from those in human-to-human communications. To deeply understand M2M communications in 3GPP, in this article, we provide an overview of the network architecture and features of M2M communications in 3GPP, and identify potential issues on the air interface, including physical layer transmissions, the random access procedure, and radio resources allocation supporting the most critical QoS provisioning. An effective solution is further proposed to provide QoS guarantees to facilitate M2M applications with inviolable hard timing constraints.
Title: Optimal Spectrum Sharing in MIMO Cognitive Radio Networks via Semidefinite Programming Authors: Ying Jun (Angela) Zhang and Anthony Man-Cho So Source: IEEE Journal on Selected Areas in Communications, vol. 29, no. 2, pp. 362-372, Feb. 2011
Abstract: In cognitive radio (CR) networks with multiple-input multiple-output (MIMO) links, secondary users (SUs) can exploit "spectrum holes" in the space domain to access the spectrum allocated to a primary system. However, they need to suppress the interference caused to primary users (PUs), as the secondary system should be transparent to the primary system. In this paper, we study theoptimal secondary-link beamforming pattern that balances between the SU's throughput and the interference it causes to PUs. In particular, we aim to maximize the throughput of the SU, while keeping the interference temperature at the primary receivers below a certain threshold. Unlike traditional MIMO systems, SUs may not have the luxury of knowing the channel state information (CSI) on the links to PUs. This presents a key challenge for a secondary transmitter to steer interference away from primary receivers. In this paper, we consider three scenarios, namely when the secondary transmitter has complete, partial, or no knowledge about the channels to the primary receivers. In
9
particular, when complete CSI is not available, the interference-temperature constraints are to be satisfied with high probability, thus resulting in chance constraints that are typically hard to deal with. Our contribution is fourfold. First, by analyzing the distributional characteristics of MIMO channels, we propose a unified homogeneous quadratically constrained quadratic program (QCQP) formulation that can be applied to all three scenarios, in which different levels of CSI knowledge give rise to either deterministic or probabilistic interference-temperature constraints. The homogeneous QCQP formulation, though non-convex, is amenable to semidefinite programming (SDP) relaxation methods. Secondly, we show that the SDP relaxation admits no gap when the number of primary links is no larger than two. A polynomial-time algorithm is presented to compute the optimal solution to the QCQP problem efficiently. Thirdly, w- - e propose a randomized polynomial-time algorithm for constructing a near-optimal solution to the QCQP problem when there are more than two primary links. Finally, we show that when the secondary transmitter has no CSI on the links to primary receivers, the optimal solution to the QCQP problem can be found by a simple matrix eigenvalue-eigenvector computation, which can be done much more efficiently than solving the QCQP directly.
Title: Delay and Capacity Tradeoff Analysis for MotionCast Authors: Xinbing Wang, Wentao Huang, Shangxing Wang, Jinbei Zhang, Chenhui Hu Source: IEEE Transactions on Networking, Vol. 19, No. 5, pp. 1354-1367, Mar. 2011
Abstract: In this paper, we define multicast for an ad hoc network through nodes' mobility as MotionCast and study the delay and capacity tradeoffs for it. Assuming nodes move according to an independently and identically distributed (i.i.d.) pattern and each desires to send packets to k distinctive destinations, we compare the delay and capacity in two transmission protocols: one uses 2-hop relay algorithm without redundancy; the other adopts the scheme of redundant packets transmissions to improve delay while at the expense of the capacity. In addition, we obtain the maximum capacity and the minimum delay under certain constraints. We find that the per-node delay and capacity for the 2-hop algorithm without redundancy are Θ(1/k) and Θ(n log k), respectively; for the 2-hop algorithm with redundancy, they are Ω(1/k√(n log k)) and Θ(√(n log k)), respectively. The capacity of the 2-hop relay algorithm without redundancy is better than the multicast capacity of static networks developed by Li [IEEE/ACM Trans. Netw., vol. 17, no. 3, pp. 950-961, Jun. 2009] as long as k is strictly less than n in an order sense, while when k=Θ(n), mobility does not increase capacity anymore. The ratio between delay and capacity satisfies delay/rate ≥ O(nk log k) for these two protocols, which are both smaller than that of directly extending the fundamental tradeoff for unicast established by Neely and Modiano [IEEE Trans. Inf. Theory, vol. 51, no. 6, pp. 1917-1937, Jun. 2005] to multicast, i.e., delay/rate ≥ O(n k2). More importantly, we have proved that the fundamental delay-capacity tradeoff ratio for multicast is delay/rate ≥ O(n log k), which would guide us to design better routing schemes for multicast.

Joint Wireless Information and Power Transfer
Microwave-enabled wireless power transfer (WPT) is an emerging technology to solve the problem of limited device battery life. By leveraging the far-field radiation characteristics of microwave, stable energy could be delivered to energy-harvesting devices over the air without disruption to the use. With microwave-enabled WPT, information could also be jointly transmitted with energy using the same waveform. As shown in Fig. 1, such a design paradigm is referred to as simultaneous wireless information and power transfer (SWIPT), which is more efficient in spectrum usage than transmitting information and energy in orthogonal time or frequency channels.
Fig. 1. Network Model of SWIPT. The application of MIMO technology could significantly enhance the performance for both energy and information transmission. In [1], we demonstrate the use of MIMO to achieve energy beamforming (EB) gain. By carefully shaping the transmit waveform at each antenna, EB could focus the transmit power in a small region of space to bring significant improvement to the energy transfer efficiency. However, when information is jointly transmitted with energy, the optimal EB design is in general different from the well-known spatial multiplexing technique used to maximize information rate in MIMO communications. In light of this, we study the design tradeoffs in MIMO-SWIPT system for two scenarios: the energy and information receivers are either separated (e.g., Rx3 and Rx4 in Fig. 1) or co-located (e.g. Rx1 and Rx2 in Fig. 1). In particular, for the
12
co-located receivers case, we propose several practical receiver structures for a device to harvest energy and decode information simultaneously, including time-switching, power-splitting and antenna-switching receivers. Then, we characterize the rate-energy performance tradeoffs under the two scenarios and different receiver structures, by deriving their respective achievable rate-energy regions. The receiver structures proposed and fundamental tradeoffs revealed in this paper have inspired substantial follow-up works in the design and performance evaluation of various types of SWIPT systems.
Another fundamental difference between wireless information and power transfer is their performances subject to channel fading and interference. While deep channel fading degrades the performance of both information decoding (ID) and energy harvesting, interference is only harmful to ID but in fact helpful to increase the harvested energy for EH receiver. In [2], we consider a time-switching SWIPT receiver to opportunistically switch between EH and ID in the presence of time-varying channel and interference, to jointly optimize the EH and ID performance. For information transmission, we consider two performance metrics, i.e., outage probability and ergodic capacity. For both cases, we derive the optimal ID/EH mode
switching rules at the receiver to optimize the outage probability/ergodic capacity versus harvested energy trade-offs. In general, our results show that the receiver should switch to perform ID when the received signal (information and interference) is relatively weak and the signal-to-noise ratio (SNR) is sufficiently high, and EH otherwise. Intuitively, this is because the ID receiver gains less than the EH receiver when the interference is strong (harmful for ID but helpful for EH), and when the channel is in good condition (logarithmic increase in rate for ID but linear increase in energy for EH). Besides, we also jointly optimize the transmitter information/energy scheduling and power control with the receiver ID/EH mode switching when channel state information is known by the transmitter.
Besides the two papers introduced above, we have also devoted great research efforts to solve other important problems in SWIPT, and the more general area of wireless powered communications. For instance, energy beamforming based on limited channel feedback or partial channel estimation; throughput optimization in wireless powered communication network (WPCN) where the information transmitting devices are powered by means of WPT; multi-cell network capacity of wireless powered cognitive radio systems, etc. We believe that the design of wireless powered communications will spur significant research innovations in wireless technologies, as the future wireless systems is expected to be a mixture of wireless information and energy transfer, with microwave-enabled WPT, SWIPT and WPCN being important building blocks.

Summary Report from Dr. Tarik Taleb On my first DLT tour, I visited both Beijing and Shanghai where I delivered industry-focused talks on how to build mobile
networks as a cloud service, referring to emerging technologies such as the network function virtualization and mobile
cloud computing. The talks were delivered at the Chinese Academy of Science, Beijing University of Post and
Telecommunications and the Shanghai Jiao Tong University. They were very well attended. The audience, principally
consisting of post-grad students and post-doc researchers, was very active asking plenty of questions and showed great
interest in the topics of the talks. Many students also followed up asking questions offline by email. The tour was also very
successful in terms of building relationships with the faculty staff of the three visited institutes, not to mention promoting
IEEE ComSoc and its activities within the Chinese community of students, the largest in the World. In my humble opinion,
the given talks were also beneficial for young graduate students to help them define research topics of potential interest to
industry.
Finally, I would like to express my sincere gratitude to the organizers of the Beijing ComSoc and Shanghai Comsoc
chapters for making of my stay in China a memorable one. I really enjoyed every conversation I had with each of them and
am looking forward opportunities to meet them in the future and collaborate with them on timely research topics.

2014 AP DLT #7: 4 – 11 May 2014
Lecturer: Xiaoming Fu
Hosting Chapter 2014 Chapter Chairs
Shanghai ComSoc Chapter Xinwan Li
Beijing ComSoc Chapter Xiaofeng Tao Dr. Xiaoming Fu conducted his technical presentation on “Scaling Micro-blogging Services with Divergent Traffic Demands” at the following venues:
1. Shanghai – 5 May 2014 (Monday) Venue: Shanghai Jiao Tong University 2. Beijing – 7 May 2014 (Wednesday)
Venue: Beijing University of Posts and Telecommunications (BUPT) 3. Beijing – 8 May 2014 (Thursday)
Venue: Chinese Academy of Science Summary Report from Dr. Xiaoming Fu
Having the opportunities in delivering several lectures on data networking and Internet computing in Asia and Pacific,
Europe, North America and South America, I have been honored appointed as an IEEE Communications Society
Distinguished Lecturer starting January 2014.
China is my home country where I grew up and got educated. In the recent years, I have participated in several
EU-sponsored or bilateral projects involving some Chinese partners, which brought me a lot of fun and fresh experiences
with different Chinese colleagues. Nevertheless, my personal feeling is that they are more project-driven, unlike a global
15
organization such as IEEE ComSoc which could bring a different value for the whole research community.
Upon the invitations of IEEE ComSoc Shanghai Chapter and Beijing Chapter, I had the opportunity to make my first DLT
to China. IEEE ComSoc Asia-Pacific Project / Admin Executive Ewell Tan was extremely efficient and professional in
communicating with local chapters and sectors on my DLT schedule. The initial thought was to deliver lectures in Nanjing,
Shanghai, Wuhan and Beijing, but due to time conflicts I could not visit Wuhan, and some of my lectures (“Fine-Grained
Multi-Resource Scheduling in Cloud Datacenters” at Nanjing University in Nanjing and Fudan University in Shanghai,
as well as “Content Distribution: from Client/Server to Content-Oriented Publish/Subscribe System” at Tsinghua
University in Beijing) were delivered outside the DLT program due to synchronization issues with the local chapters.
Although these lectures were not directly under the IEEE DLT flag, Ewell encouraged me to deliver them as planned,
which actually turned out to be well perceived by colleagues and students in these institutions.
After my Nanjing trip, I arrived in Shanghai on 4th
May and gave a lecture at Fudan University on 5th
May morning. After
lunch, I visited Shanghai Jiao Tong University (SJTU), one of the top engineering universities in China, for the first time,
and gave my first DLT lecture on the design, implementation and evaluation of scalable microblogging systems. There
were over 30 attendees, some faculty members, and many graduate and undergraduate students from SEIEE, including all
students from a seminar course usually planed for that slot. The audience showed a great interest in the topic, and I
enjoyed the interactions during the talk and in the Q&A period after the presentation. In particular, I received emails from
some students after the seminar. Some of them wanted to study in Göttingen and work on related topics. My hosts Prof.
Xinwan Li (IEEE ComSoc Shanghai Chapter Chair, and Vice Dean of SJTU-Michigan University Joint Institute), Prof.
Xinbing Wang (IEEE ComSoc Shanghai Chapter Chair), and Dr. Xiaohua Tian were very thoughtful, and warmly invited
to visit their labs in SEIEE as well as the Michigan University-SJTU Joint Institute. From my personal feeling, SJTU is
certainly China’s most modern university owing to their broad visions, maximal elimination of bureaucracy and well
adoption of western educational culture. SJTU has also its open mind to attract world-class experts and scientists to work
there or collaborate with them. It’s amazing that many faculty members hold U.S., Canadian, Japanese or European PhD
degrees, and they are implementing the tenure-track system with competitive salary and expectations. SJTU’s Minhang
campus is huge, beautiful, and elegant; I had not the time to visit it except the office buildings of Prof. Li, Prof. Wang and
an in-campus coffee bar, but I would definitely see it around in a next trip.
My next DLT lecture took place in Beijing University of Posts and Telecommunications (BUPT) on 7th
May 2014. In the
classroom I was delighted to meet another DLT lecturer Dr. Tarik Taleb, a colleague from NEC Europe Networking Lab,
Heidelberg, Germany, who gave a lecture right before mine. We knew each other since quite some time ago and both are
located in Germany. His lecture focused on the cloud computing architecture perspectives, while mine more focused on
the Internet service and systems point of view. The audience was roughly 40, mostly faculty members and graduate
students from Communications Engineering, from which I saw there was a keen interest in learning about the social
networks domain and other emerging Internet services. After the lecture I had also the pleasure to meet our current EU
project partner (Prof. Lin Zhang and Prof. Jun Guo) and IEEE ComSoc Beijing Chapter Chair Prof. Xiaofeng Tao, and
discussed some issues related to crowdsourcing and mobile cloud computing.
In summary, I had a pleasant and fruitful first DLT in China. I enjoyed it very much - thanks the generous support of IEEE
ComSoc and also the hospitality of local chapters.
Summary Report from Beijing ComSoc Chapter (by Waheed ur Rehman) IEEE Communications Society (ComSoc), Beijing Chapter arranged lectures on 7
th and 8
th May, 2013 at Beijing
University of Posts and Telecommunication (BUPT) and Chinese Academy of Science (CAS). Dr. Xiaoming Fu was
invited to give the 50 minutes lectures on ‘Scaling Microblogging Services with Divergent Traffic Demands’ at both
venues. Prof. Xiaofeng Tao, Chair of ComSoc Beijing Chapter, hosted the seminar at BUPT and Dr. Xue Han hosted it at
CAS. There were totally about 80 attendees at both venues, including university students, academic researchers and
public participants from ICT related Industries. The related information about the lectures, including abstract of the talk
and a brief introduction of Dr. Fu was E-mailed to IEEE ComSoc Beijing Chapter Members by Prof. Tao. Also, the lecture
announcements were notified on the universities website announcement boards by the school academic committees.
The lecture was started from the discussion of growing tendencies of social media sites and the amount of traffic they
generate. Today's microblogging services such as Twitter have long outgrown their initial designs as SMS-based social
networks. Instead, a massive and steadily-growing user population of more than 100 million is using Twitter for
everything from capturing the mood of the country to detecting earthquakes and Internet service failures. It is
unsurprising that the traditional centralized client-server architecture has not scaled with user demand, leading to server

overload and significant loss of availability. Social media sites such as Twitter performance and availability is not
satisfying, even at normal time. Some short term solutions such as per-user request and connection limits, network usage
monitoring and doubling the capacity of internal networks fix few strings and the problems are still there.
A novel system architecture, Cuckoo was introduced, which is tailored for microblogging to address scalability issues.
This architecture relieve main server burden and achieve scalable content delivery by decoupling the dual functionality
components. Cuckoo offloads processing and bandwidth costs away from a small centralized server base while ensuring
reliable message delivery. A detailed measurement is done over Twitter and is found brings significant benefits such as
bandwidth savings, CPU and memory reduction and good performance of content delivery/dissemination.
Dr. Fu took 50 minutes for his lectures at BUPT and CAS. Participants were very interested in the topic and contents.
Notes were taken and questions were asked during the lecture by many participants. Question-answer continued after the
lecture for additional 20 minutes. The questions were covering both the basic and professional aspects of the topic. Due to
the shortage of Q/A time, several participants had further exchanges with Dr. Fu after the session ended. After the
lecture, Dr. Fu had a further talk with various professors in BUPT/CAS and visited the related labs.
IEEE ComSoc Beijing Chapter is very pleased to host Dr. Xiaoming Fu and believe that his lecture brought many
significant ideas in the minds of young researchers and at the same time cleared many doubtful minds. We also hope that
Dr. Fu also had a pleasant experience on his visit to Beijing.

networks” were given by Dr. Granelli for 2 hours. End of each topic, we had a discussion time and 3 or 4 questions were
raised for each topic from audiences. Each question was not superficial but insightful, so extensive and fruitful
discussions were made between the lecturer and audiences. After the finish of this seminar, some enthusiastic participants
directly contacted Dr. Granelli for more detailed discussion and further information. We heard many participants were
satisfied Dr. Granelli’s exciting lecture. So the lecture was successfully concluded.
17
Regarding lecture topic, we were proposed four potential topics with short description during the arrangement of this
lecture. We contacted some chapter members to ask which topic was attractive for our chapter members. We heard the
above two topics were interesting, so we asked Dr. Granelli to talk two topics in the lecture. This was very useful
procedure to attract the chapter member’s attention and interest to this lecture.
We thank Dr. Fabrizio Granelli for his great lecture and we also appreciate various supports from the related
organizations including IEEE Communications Society, and IEEE Asia-Pacific / Communications Society Office. We are
looking forward to have similar opportunities in the near future.

research staff and students from Deakin University, RMIT University, a few researchers from China and Japan as well.
About half of the audiences are IEEE members.
The talk was extremely welcomed by the audience, and many questions were asked and answered. The talk clearly defined
SDN as the second wave of cloud computing, which is significantly helpful for us to understand SDN, a new uncharted
land. All research staff and students highly praised the talk.
I truly believe the distinguished lecture is a great promotion for member recruitment and retention. The only improvement
that I have in mind is that we need more such kind of distinguished lectures at Melbourne, Australia. As a result, we would
like to host more DL in the future.

Lecture 2: Indian Institute of Technology (IIT, Hyderabad) 3. 5 September 2014 (Friday)
Lecture 3: Birla Institute of Technology and Science (BITS, Hyderabad)
Summary Report from Hyderabad ComSoc Chapter Prof. Sumit Roy visited Hyderabad and delivered 3 distinguished lectures hosted by the IEEE COMSOC /SP Hyderabad
Joint Chapter.
19
The first lecture was organized by IIIT Hyderabad and COMSOC/SP Hyderabad Joint Chapter at the IIIT Hyderabad,
Gachibowli campus on 4 September. The lecture topic was “White Space Networking: Integrated Sensing and Database
Architecture.” The lecture was attended by 22 guests including 7 IEEE members. The second lecture was organized by the
IEEE Student Branch of BITS PILANI Hyderabad Campus and COMSOC/SP Hyderabad Joint Chapter at the BITS Pilani,
Hyderabad campus on 5 September at 5 pm. The lecture was attended by 64 guests including 22 IEEE members.
Prof. SUMIT ROY (Dept. of Electrical Engineering, University of Washington, Seattle) delivered the lecturs in a splendid
fashion. He took his time in getting acquainted with the audience (which largely consisted of 3rd
and 4th
year students,
along with a handful of M.E students and PhD Research Scholars). Impressed by the number of IEEE members presented
at the lecture, Prof. Sumit Roy went on to say that being a part of the IEEE student chapter is of great value, the reason
being that it not only exposes students to latest developments in the technological sector but also helps them during
placements and research. He mentioned many digital journals which IEEE had published over the years and also various
conferences conducted by the IEEE Communications Society such as the IEEE GLOBECOM, IEEE INFOCOM, IEEE
CCNC, IEEE PIMRC and IEEE WCNC.
Prof. Sumit Roy then started his lecture with a question: "What are White Spaces?" upon receiving an answer from an
eager student, he went on to describe in depth his topic. He explained how unused or "free" regions in the radio spectrum
(called White Spaces) could be harnessed to our advantage in order to solve the global crisis of inadequacy of unlicensed
service bands. The difference between supply and demand has become huge and more offload is required in terms of
unlicensed service. This could be solved with the use of white spaces. He talked about the advent of 4G in the US due to
increasing network traffic and went on to highlight the problem of SPECTRUM CRUNCH, which was caused due to the
lack of sufficient network capacity at crucial times. Overall, the presentation was highly enlightening and it gave the
students a new area to venture into.
The third lecture was organized by IIT Hyderabad and COMSOC/SP Hyderabad Joint Chapter at the IIT Hyderabad,
ODF campus on 5 September at 10 pm followed by discussions with faculty and students of Dept of EE, IIT Hyderabad.
Prof. Sumit Roy introduced the interference issues in the Distributed Small Cells and proposed time-frequency ALOHA as
a solution. A video link of the lecture is available at http://youtu.be/e4n20Yj4wRM. The lecture was attended by 49 guests
including 9 IEEE members and resulted in discussions on CR and communications in general.
IIT Hyderabad, BITS PILANI, Hyderabad, IIT Hyderabad and IEEE COMSOC/SP Hyderabad chapter would like to
thank Prof. Roy for the exciting lectures and the insightful discussions.

1.5 Report on Activities for Students from Local Chapters
Workshop on SCILAB June 18, 2014 The IEEE Communications Society Madras Chapter organized a one-day workshop on SCILAB, an open source alternative for MATLAB, on June 18, 2014. MATLAB is high-level technical computing software that has been widely in use among engineering community. It took vital place in many engineering course syllabus, particularly in Electrical and Electronics branches. There are many institutions they cannot afford the huge licensing fee and started looking for alternate open source software equivalent to MATLAB. SCILAB is an open source equivalent to MATLAB. SCILAB was developed by INRIA (France) for system control and signal processing applications. It is also a vector-based program. SCILAB package also includes SCICOS that is an open source alternative to SIMULINK. Mr. P. Subramanian, Associate Professor, ECE Department, Aarupadai Veedu Institute of Technology, Vinayaka Missions University and Secretary, IEEE ComSoc Madras Chapter welcomed the gathering and gave an introduction to SCILAB and its applications.
