Kaupunki digitalisaation kasvualustana 2015 11-05
Kaupunkien uutena roolina on toimia innovaatioekosysteemin kasvualustana, mahdollistajana ja orkesteroijana. Kaupunkien liiketoimintamallin muutos asiakkuus- ja toimintaperustaiseksi mahdollistaa kokeilevan kehityskumppanuuden digitalisaation hyödyntämiseksi. Kuutoskaupunkien 6Aika yhteistyönä synnytetään uutta alustaa digitalisaatiolle: painopistealueina ovat avoimet innovaatioalustat, avoin osallisuus ja asiakkuus ja avoin data.
Ijri te-03-013 modeling and thermal analysis of air-conditioner evaporator
Air conditioning evaporator works by absorb heat from the area (medium) that need to be cooled. It does that by maintaining the evaporator coil at low temperature and pressure than the surrounding air. Since, the AC evaporator coil contains refrigerant that absorbs heat from the surrounding air, the refrigerant temperature must be lower than the air.
In our project we have modeling an air-cooled evaporator for a home 1.5ton air conditioner. Presently the material used for coils is copper and the material used for fins is copper or aluminum. A 3D model of the evaporator is done in parametric software Pro/Engineer.
To validate the temperatures and other thermal quantities like flux and gradient, thermal analysis is done on the evaporator coil by applying properties copper and suitable material like aluminum. And also we are varying inside cooling fluid Hydrocarbon (HC) and Hydro chloroflouro carbon (HCFC).The best material for the evaporator of our design can be checked by comparing the results.
Thermal analysis is done in ANSYS.

The present paper deals with the effect of volume fraction of fillers on the thermal Properties of polymer composites. This work sees an opportunity of enhancement on insulation capability of a typical fiber reinforced polymer composite. To validate this mathematical model, a set of epoxy based composites, with fiber content ranging 4.38 to 20.10% of volume fractions have been prepared by simple hand lay-up technique. For preparing the composite, natural fiber i.e. Pine apple leaf fibers are incorporated in Epoxy Resin. Thermal conductivities of these composite samples are measured as per ASTM standard E-1530 by using the Unitherm™ Model 2022 tester, which operates on the double guarded heat flow principle at the temperature ranging from 30˚C to 150˚C. And also the Specific Heat of the powdered samples are measured by using Differential Scanning Calorimeter (DSC). By using the MATLAB the numerical analysis is carried out to find the value of Thermal Diffusivity with varying temperatures. It was observed that the thermal diffusivity varies with fiber concentration, but the variation of thermal diffusivity with varying temperature was not so significant.

Ijri ece-01-01 joint data hiding and compression based on saliency and smvq
Global interconnect planning becomes a challenge as semiconductor technology continuously scales. Because of the increasing wire resistance and higher capacitive coupling in smaller features, the delay of global interconnects becomes large compared with the delay of a logic gate, introducing a huge performance gap that needs to be resolved A novel equalized global link architecture and driver– receiver co design flow are proposed for high-speed and low-energy on-chip communication by utilizing a continuous-time linear equalizer (CTLE). The proposed global link is analyzed using a linear system method, and the formula of CTLE eye opening is derived to provide high-level design guidelines and insights.
Compared with the separate driver–receiver design flow, over 50% energy reduction is observed.
Accounting for Website Security in Higher Education
Online threats against web applications are growing at an exponential rate and is estimated to continue to grow in the coming years.
Higher education finds itself in a precarious position trying to balance the need to provide services like external websites to it's various functional groups, while working to stay ahead of such threats.
This is further exasperated by the adoption and deployment of open-source CMS applications like WordPress and Drupal.
In this talk, Tony proposed to explore the latest tactics, techniques and procedures being employed by cyber criminals, their threats to Higher Education institutions and provide a security framework from which organizations can expand on within their own organizations.

Uber in China: What's next? (Study from DDIM 10 class)
DDIM 10
Uber entered in the chinese market in 2013. They have launched in the market Uber Black, UberX, People's Uber (a non for profit private car sharing) and other customized products such as UberGreen. Despite all the money they spent, today Uber has only 8,2% of the market in China and its major competitor DidiKuaidi owns more than 78% of the market share. Our work is focused on the analysis of the various options, the selection of the best one according to cost criteria and results in terms of level of competiton. Then we build a 10-years action plan.
