We study the hand p{versions of the Galerkin boundary element method for integral equations of the rst kind in 2D and 3D which result from the scattering of time harmonic acoustic waves at hard or soft scatterers. We derive an abstract a{posteriori error estimate for indeenite problems which is based on stable multilevel decompositions of our test and trial spaces. The Galerkin error is estimat...

This work investigates the effects of aging and voltage scaling in neutron-induced bit-flip in SRAM-based Field Programmable Gate Array (FPGA). Experimental results show that aging and voltage scaling can increase in at least two times the susceptibility of SRAM-based FPGAs to Soft Error Rate (SER). These results are innovative, because they combine three real effects that occur in programmable...

This paper describes a tunable transient filter (TTF) design for soft error rate reduction in combinational logic circuits. TTFs can be inserted into combinational circuits to suppress propagated single-event transients (SETs) before they can be captured in latches or flip-flops. TTFs are tuned by adjusting the maximum width of the propagated SET that can be suppressed. A TTF requires 6–14 tran...

Soft errors have been a critical reliability concern in nanoscale integrated circuits, especially in sequential circuits where a latched error can be propagated for multiple clock cycles and affect more than one output, more than once. This paper presents an analytical methodology for enhancing the soft error tolerance of sequential circuits. By using clock skew scheduling, we propose to minimi...

This work investigates the e↵ects of temperature and voltage scaling in neutron-induced bit-flip in SRAM memory cells. Proposed approach allows determining the critical charge according to the dynamic behaviour of the temperature as a function of the voltage scaling. Experimental results show that both temperature and voltage scaling can increase in at least two times the susceptibility of SRAM...

We propose a low complexity soft-input/soft-output multiuser detector based on probabilistic data association. This new scheme has a total computational complexity of O(K2) + O(2ν) per user, which is the same as the complexity of linear soft-input/soft-output multiuser detectors. Numerical results demonstrate that the proposed detector, together with rate 1/2 error control coding, outperforms l...

In order to reduce overall system costs, the aerospace industry has been increasingly using commercial off the shelf components in their products. The sensitivity of these products to radiation induced soft errors becomes a major concern. In this paper, we propose a method to increase the reliability of a given off the shelf component by manipulating the software-based error correction algorith...

The continued scaling of photolithographic fabrication techniques down to 32 nanometers and beyond faces enormous technology and economic barriers. Selfassembled devices such as silicon nanowires or carbon nanotubes show promise to not only achieve aggressive dimensions, but to help address power and other gating issues in system architecture, while potentially helping contain rampant increases...

the main purpose of this paper is to introduce and study new classes of soft closed sets like soft regular generalized b-closed sets in soft topological spaces (brie y soft rgb-closed set) moreover, soft rg-closed, soft gpr-closed, soft gb-closed, soft gsp-closed, soft g-closed, soft gb-closed, and soft sgb-closed sets in soft topological spaces are introduced in this paper and we investigat...
