sures experienced by a pipeline can be either beneficial or detrimental from an operational performance perspective, depending on the amount, the two phase regime of the mixture (whether homogeneous or slug) and the nature and cause of the transient. It is generally held that when free (undissolved) air, or gas, is present in a hydraulic system, it can greatly reduce the surge pressure levels b...

We take an important step forward in making Oblivious RAM (O-RAM) practical. We pro-pose an O-RAM construction achieving an amortized overhead of 20 ∼ 35X (for an O-RAMroughly 1 terabyte in size), about 63 times faster than the best existing scheme. On the theoreticfront, we propose a fundamentally novel technique for constructing Oblivious RAMs: specifi-cally, we partition a bi...

For 6 years adult, non-synchronized Hampshire ewes (n=2,5,8,8,9 and 12) and rams (n=6,10,12,11,11 and 9) were maintained separately and released to contiguous pastures having in common a woven-wire fence about 80m long and 1.1m high. Natural estrous cycles were monitored daily by observations of ram-seeking behavior as defined as a ewe being persistent in staying at the common fence with attent...

We define the concept of and present provably secure constructions for Anonymous RAM (AnonRAM), a novel multi-user storage primitive that offers strong privacy and integrity guarantees. AnonRAM combines privacy features of anonymous communication and oblivious RAM (ORAM) schemes, allowing it to protect, simultaneously, the privacy of content, access patterns and user’s identity, from curious se...

Oblivious RAM (O-RAM) is a useful primitive that allows a client to hide its data access patterns from an untrusted server in storage outsourcing applications. This paper proposes novel O-RAM constructions that achieves poly-logarithmic worst-case cost, while consuming constant client-side storage. Our techniques for constructing Oblivious RAM are fundamentally different from previous approache...

Nowadays, hydropower plays an essential role in the energy market. Due to their fast response and regulation capacity, hydraulic turbines operate at off-design conditions with a high number of starts and stops. In this situation, dynamic loads and stresses over the structure are high, registering some failures over time, especially in the runner. Therefore, it is important to know the dynamic r...

Garbled RAM, introduced by Lu and Ostrovsky (Eurocrypt 2013), provides a novel method to garble RAM (Random Access Machine) programs directly. It can be seen as a RAM analogue of Yao’s garbled circuits such that, the size of the garbled program and the time it takes to create and evaluate it, is proportional only to the running time of the RAM program, avoiding the inefficient process of first ...
