Waste Water Treatment Fundamentals, Plant Monitoring, and Operations

Dr. P.G. Rathnasiri, University of Moratuwa, Sri Lanka

May 29, 2017

9:00am

Workshop introduces fundamentals of waste water treatment, operation and monitoring. Discussion begins with characterization of wastewater/solid waste and different techniques available. Then biological wastewater treatment will be classified with the objective of understanding aerobic, anaerobic, suspended, attached growth processes and will be presented with established industrial wastewater treatment plants. Overview of organic carbon, bio Phosphorous and nitrogen removal will be presented. Successful design and operation of any wastewater/solid waste treatment plant require knowledge on microorganisms involved, specific reactions they perform, nutritional needs and more importantly environmental and operating parameters which affect for their better performance. Different unit operations belong to primary, secondary and tertiary treatment and their performance will be also discussed. Reactor types used in typical aerobic and anaerobic processes will be presented with the objective of guiding environmental engineer for screening different options. Significance of applying simulations for analysis of wastewater treatment plant will be presented with AQUASIM 2.1f dynamic simulator.

Photovoltaic Power Conversion Systems: Current Trends

Dr. Dulika Nayanasiri, University of Moratuwa, Sri Lanka

Photovoltaic (PV) power conversion systems gain attraction due to low energy pay-back time and low carbon foot print compared to other renewable energy technologies such as wind. Centralized and distributed power conversion systems are used to convert solar energy into electrical energy. Distributed PV power conversion systems are frequently used in small and medium scale applications. Module and sub module level power converters are used in distributed systems such as roof-top PV. However, intermittent nature and seasonal behavior of the solar energy limits the applications of PV as a continuous power source. Energy storing element can be integrated to the system to circumvent this drawback. Application specific energy storing methods improve power processing capability of the system. Such an integration can be done using DC systems due to in-born characteristics of renewable generators and energy storing elements. This gives rise to concept of micro and nano-grids based on DC. DC nano-grids with integrated communication capabilities improve user experience with respect to the concept of zero net energy home. Power electronic converters and communication protocols having energy transfer capability play a significant role in the realization of such a system.

In this workshop, we are going to talk about existing PV power conversion systems architectures and converter topologies to identify limitations of the state of the art technologies. The proposed system architectures such as networked DC nano-grids to circumvent those limitations will be discussed emphasizing current trends.


Modelling Wireless Sensor Networks with Network Simulator 3

Dr. Rajiv Pandey, Amity University Lucknow Campus, India

May 29, 2017

1:30pm

The workshop aims to write code to model Wireless Sensor Networks (WSN). The Simulator shall be of significance when a researcher intends to model and analyze the behavior of IOT devices. This hands on workshop introduces the installation and use of Network Simulator 3 on a Linux virtual machine. The Participants will be given hands on through the installation and visualization features using various Python commands. Target Audience includes Postgraduate students, scientists, and professional engineers who plan pursue IOT related research and development.


Writing, Publishing, Presenting, and LaTeX

Dr. Ranga Rodrigo, University of Moratuwa, Sri Lanka

May 29, 2017

1:30pm

In this basic workshop, I will discuss academic writing, publishing, presenting at a conference, and using LaTeX for writing manuscripts. A manuscript written in clear, concise, and vigorous language makes the reviewers, readers and, ultimately, author’s content. I will present some tips to give a manuscript this power. To end up in a journal or a conference, the manuscript must go through the publication process. Information about this process of publication will follow the tips on writing. Characteristics of good writing are invariably useful to make a good presentation at a conference. The latter part of the workshop will be on using LaTeX for manuscripts and presentation slides. LaTeX is the standard in our field for any scientific publication, whether it is a journal article, conference paper, book, or set of slides. This workshop, thus, will equip the students and anyone interested on tools and tips for writing and presenting.
