Network analysis of prion disease

Newaz, Khalique; Bera, Debajyoti (Advisor) (2015-05-18)

Prion diseases are transmissible neuro-degenerative diseases that arises due to conformational change of normal cellular prion protein (PrPc ) to protease-resistant isofrom (rPrPSc ). Deposition of misfolded PrPSc proteins ...
Scalable algorithms for spatial-textual data join

Gupta, Vivek; Goyal, Vikram (Advisor) (2015-05-27)

Spatio-textual similarity join retrieves a set of pairs of objects wherein objects in each pair are close in spatial as well as textual dimensions. A lot of work has been done in the spatial dimension but no work has been ...
Utility-based control flow discovery from business process event logs

Anand, Kritika; Sureka, Ashish (Advisor) (2015-06-09)

Process Aware Information Systems (PAIS) are IT systems which support business processes and generate event-logs as a result of execution of the supported business processes. Fuzzy-Miner (FM) is a popular algorithm within ...
Vidushi : parallel implementation of alpha miner algorithm and performance analysis on CPU and GPU architecture

Kundra, Divya; Sureka, Ashish (Advisor) (2015-06-16)
