1st Talk:

Title: Big data meets renewable energy: Building a real time asset management platform for renewable energy

How does one cope with some[masked] wind turbines worldwide, each delivering 100+ measurements per second? How do you guarantee profitable operations of an industry worth $110 billion investments globally, making it one of the fastest growing industrial segments in the world?

In this talk, we discuss how WinJi built its TruePower Asset Management Platform. In particular, we will discuss the overall architecture and the motivation behind it (lambda architecture, data-vault, in-stream analysis), the physics behind the data (wind measurement corrections, in-stream calibration of turbine efficiency using neural networks) as well as the business case (analytics of lost production opportunities, predictive maintenance, expected power prediction & “day ahead” production forecast).

Dr. Stamatis Stefanakos is a managing director with D ONE, a premium business consultancy headquartered in Zurich. He advises his clients in data analytics focusing on architecture and strategy. He holds a PhD in theoretical computer science from the Swiss Federal Institute of Technology Zurich (ETH). He received his diploma from University of Patras in 2000.

2nd Talk:

Title: Lead scoring & grading: A near live combined implementation in a SaaS company

The combination of lead scoring and lead grading aims at optimising the usage of sales team resources. This is done by allocating to them the most qualified leads that have the best chances to match the company’s customer profile. This is a high-level view on how a near-live combined analytical approach was implemented in Workable using data from 7 different data sources.

Dr. Lefteris Mantelas is a BI & Analytics professional that recently moved to Beat (up to recently Taxibeat) from Workable. Before that, he had worked on consulting firms (EY & IRi) on analytics projects and in academia (FORTH). He holds a BA in Applied Mathematics from the University of Crete, an MSc in Geoinformatics and a PhD in Urban Growth Modelling from NTUA. For the last 10 years, he has been applying data analytics and modeling to solve problems and support intelligent business decisions on various areas and domains.
