FaCT: A Flexible, Constant-Time Programming Language

Sunjay Cauligi, Gary Soeller, Fraser Brown, Brian Johannesmeyer, Yunlu Huang, Ranjit Jhala, Deian Stefan
2017 2017 IEEE Cybersecurity Development (SecDev)  
We propose to solve this problem with a domainspecific language that permits programmers to intuitively express crypto routines and reason about secret values, and a compiler that generates efficient,  ...  timing-channel free assembly code.  ...  FACT: FLEXIBLE AND CONSTANT-TIME We propose to solve the hazards outlined in the previous section by designing a new, flexible and constant-time (FaCT) programming language.  ...

An Algorithm that Infers Theories from Facts

Ehud Y. Shapiro
1981 International Joint Conference on Artificial Intelligence  
A framework for inductive inference in logic is presented: a Model Inference Problem is defined, and it is shown that problems of machine learning and program synthesis from examples can be formulated  ...  The algorithm can be shown to identify in the limit [3] any model in a family of complexity classes of models, is most powerful of its kind, and is flexible enough to have been successfully implemented  ...  It can infer axiomatizations of concrete models from a small number of facts in a practical amount of time. /. Introduction.  ...

FACTS Based Static VAR Compensation using Thyristor Switched Capacitor

Manan Gupta
2018 International Journal for Research in Applied Science and Engineering Technology  
In order to calculate the power factor, the time lag between the voltage and current waveforms is measured by respective zero crossing detectors.  ...  Thus, in order to improve the power factor a capacitor bank is used in the circuit which is triggered by the SCR's.  ...  Electrical utilities generally cost higher to those industries which have a constant low power factor.  ...

Coupled temporal scoping of relational facts

Partha Pratim Talukdar, Derry Wijaya, Tom Mitchell
2012 Proceedings of the fifth ACM international conference on Web search and data mining - WSDM '12  
Firstly, while most previous research has focused on micro-reading approaches for temporal scoping, we pose it in a macroreading fashion, as a change detection in a time series of facts' features computed  ...  In this paper, we propose a joint inference framework for this task, which leverages fact-specific temporal constraints, and weak supervision in the form of a few labeled examples.  ...  We hope that CoTS' linear constraint specification is flexible enough to support a majority of such extensions.  ...

Approximating the safely reusable set of learned facts

Domagoj Babić, Alan J. Hu
2009 International Journal on Software Tools for Technology Transfer (STTT)  
In this paper, we formalize the notion of shared structure among verification conditions, and propose a novel and efficient approach to exploit this sharing by safely reusing facts learned while checking  ...  Although a tremendous amount of work has been done on exploiting structure at various levels of granularity, the finegrained shared structure among multiple verification conditions has been largely ignored  ...  This is trivial to accomplish by a linear time constant propagation post-processing even if the decision procedure does not make such guarantees.  ...

2014 arXiv   pre-print
The recorded data, which can exceed 1 TB in a moonless night, is compressed in real-time with a proprietary loss-less algorithm.  ...  Since properties as the gain of G-APDs depend on temperature and the applied voltage, a real-time feedback system has been developed and implemented.  ...  To keep a list of incomplete events, a double-linked list (std::list) is used keeping a constant access time for adding and removing entries.  ...
