Reconfigurable FPGAs promise high density, performance and good schedulable options with their wide range of SRAM target devices that can be hosted for any applications. The SRAM FPGAs are widely used due to their vast resources and ease to design, but critically suffers due to radiation errors called single event upsets (SEU). These errors are prominent when the FPGA device is employed beyond ...

The subjective expected utility (SEU) model rests on very strong assumptions about the consistency of decision making across a wide range of situations. The descriptive validity of these assumptions has been extensively challenged by behavioral psychologists during the last few decades, and the normative validity of the assumptions has also been reappraised by many statisticians, philosophers, ...

In the field of Artificial Intelligence many models for decision making under uncertainty have been proposed that deviate from the traditional models used in Decision Theory, i.e. the Subjective Expected Utility (SEU) model and its many variants. These models aim at obtaining simple decision rules that can be implemented by efficient algorithms while based on inputs that are less rich than what...

Existing scrubbing techniques for SEU mitigation on FPGAs do not guarantee an error-free operation after SEU recovering if the affected configuration bits do belong to feedback loops of the implemented circuits. In this paper, we a) provide a netlist-based circuit analysis technique to distinguish so-called critical configuration bits from essential bits in order to identify configuration bits ...

The Arabidopsis (Arabidopsis thaliana) gynoecium, the female floral reproductive structure, requires the action of genes that specify positional identities during its development to generate an organ competent for seed development and dispersal. Early in gynoecial development, patterning events divide the primordium into distinct domains that will give rise to specific tissues and organs. The m...

A high speed 15 ns 4 Mbits asynchronous SRAM, 500 Astand-by current, 300 Krads total dose tolerant, has been developed for space applications, using a hardened 0.25 micron 4 layers metal full CMOS process. A hierarchical organisation per IO bits has been used to achieve high speed as well as low dynamic consumption, also suited for simple SEU (single event upset) induced error corrections, allo...

Real-time kernels are often utilized to simplify the design of embedded time/safety-critical applications. However, embedded systems are sensitive to transient and other faults, each of which can lead to various errors at various system levels and can potentially result in system failure. In existing works, the real-time kernels sensitivity to transient SEU errors was studied only with the goal...

This paper explores the feasibility of Tierra-based OBC that evolves programs through a bit inversion caused by Single-Event Upset. In particular, Tierra-based OBC is applied to the evolution of the PIC assembly programs. Additionally, this paper proposes a new method that can reliably recover the broken program to the correct one. Intensive experiments reveal that (1) Tierra-based OBC cannot o...

Central to the ABCE model of flower development is the antagonistic interaction between class A and class C genes. The molecular mechanisms underlying the A-C antagonism are not completely understood. In Arabidopsis thaliana, miR172 is expressed in the inner floral whorls where it downregulates the class A gene APETALA 2 (AP2). However, what controls this predominantly inner whorl-specific expr...

A recente observação das ondas gravitacionais corrobora uma das mais interessantes previsões da relatividade geral: os buracos negros. Pois as ondas gravitacionais detectadas pela colaboração LIGO ajustam-se muito bem dentro da teoria da relatividade geral como um fenômeno produzido pela colisão de dois buracos negros. Sendo assim, a realidade f́ısica dos buracos negros parece ainda mais inegáve...
