Solid state drives (SSDs) are becoming more common with their main advantage of faster reads compared to hard disk drives (HDDs). However, writes are relatively slower, indeed asymmetric with respect to reads, unlike in HDDs where read and write are comparable. Current indexing structures were...
Lookup tables are frequently used in many applications to store and retrieve keyvalue pairs. Designing efficient lookup tables can be challenging with constraints placed on storage, query response time and/or result accuracy. This thesis proposes Geometric filter, a lookup table with a space...
By eavesdropping on a user's query in a sensor network, an adversary can deduce both the user's current location and his/her location of interest. Issuing k queries instead of one (our "k-query" scheme) protects the privacy of the user's location of interest, but facilitates the adversary...
Online trajectory prediction is central to the function of air traffic control of improving the flow of air traffic and preventing collisions, particularly considering the ever-increasing number of air travellers. In this thesis, we propose an approach to predict the mid-flight trajectory of an...
Consider a customer who needs to fulfill a shopping list, and also a personal shopper who is willing to buy and resell to customers the goods in their shopping lists. It is in the personal shopper’s best interest to find (shopping) routes that (i) minimize the time serving a customer, in order to...
