The First Europe-China Workshop on Big Data Management

Some attenders of this workshopThe first Europe-China workshop on big data management was successfully held on the 16th of May, 2016 at the Department of Computer Science, University of Helsinki. 

This one-day workshop organized by Prof. Jiaheng Lu (University of Helsinki), Prof. Xiaoyong Du (Renmin University of China), and Prof. Christian S. Jensen (Aalborg University, Denmark). The aims of this workshop were to gather experts in big data management to exchange views on cutting-edge data management problems and create opportunities for establishing new collaborations between EU and China computer scientists.

The local host Prof. Jiaheng Lu delivered the opening speech and the department head, Prof. Sasu Tarkoma introduced the research achievements of the department. Then ten speakers gave high-quality talks, which covered diverse topics on big data management, such as big data implementations, big data cleansing, spatial data, social media data, cognitive data, cloud data, graph data, streaming data and real-life examples for big data. The invited speakers were Dr. Mohammad Hoque (University of Helsinki), Heikki Hämäläinen (Eficode Oy, Finland), Prof. Hua Lu (Aalborg University), Prof. Shuai Ma (Beihang University, China), Prof. Nikos Mamoulis (University of Ioannina, Greece), Prof. Jianliang Xu (Hong Kong Baptist University), Prof. Ge Yu (Northeastern University, China), Prof. Demetris Zeinalipour (University of Cyprus), Prof. Xiaofang Zhou (University of Queensland, Australia and Soochow University, China) and Prof. Yongluan Zhou (University of Southern Denmark).

Big data management is the organization, administration and governance of large volumes of structured, semi-structured and unstructured data. The goal of big data management is to ensure a high level of data quality and accessibility for business intelligence and big data analytics applications.

More than thirty professors and students joined this workshop. The organization of workshop was assisted by PhD students Pengfei Xu, Heli Helskyaho and Chao Zhang. The presentation topics and slides about this workshop can be found at http://udbms.cs.helsinki.fi/BigData2016/.

Cold Aisle Containment in our server room

On Thursday 10 March 2011, we installed a so-called Cold Aisle Containment in the server room shared by the Department of Computer Science and HIIT. This is a rustic contraption made from transparent PE plastic, air-conditioning tubes, and a great deal of duct tape. It cuts back on the need to cool the server room very efficiently, as the air-tight plastic stops the intake and exhaust air from the servers from mixing.

HIIT study: Servers run well around zero degrees

Lots of energy can be saved by using outside air directly for cooling in data centers in the north. In a study by researchers of Helsinki Institute for Information Technology HIIT and the University of Helsinki, computers functioned correctly over extended periods of time when run in harsh winter temperatures. Commercial, off-the-shelf computers ran well even when the outside temperature was -22C (-8F).

Master's degree studies in computer science popular among international applicants

Master's degree programmes in computer science at the University of Helsinki were very popular among international applicants in spring 2010. This academic year the department of computer science at the University of Helsinki decided to offer two of its Master's degree sub-programmes, namely the programme on Algorithms and Machine Learning and the programme on Networking and Services, completely in English from the beginning of Autumn term 2010.

Esko Ukkonen’s birthday coffee

The head of the department, Esko Ukkonen, celebrated his 60th birthday. The celebration was held in Exactum at the end of January. The party was attended by employees of the Department of Computer Science and invited guests. The programme included both congratulatory speeches and songs, with a quartet from Wiipurilaisen Osakunnan Laulajat (the Viipuri students’ association singers) singing a song for a former active member. Esko was inspector in Kymenlaakson Osakunta (the Kymenlaakso students’ association) for over ten years.
