The inhalation intake fraction was used as an indicator to compare effects of desktop personalized ventilation and mixing ventilation on personal exposure to directly released simulated cough droplets. A cough machine was used to simulate cough release fro ...
An emerging area of research is to automatically compute reasonably accurate upper bounds on numerical errors, including roundoffs due to the use of a finite-precision representation for real numbers such as floating point or fixed-point arithmetic. Previo ...
Numerical software, common in scientific computing or embedded systems, inevitably uses an approximation of the real arithmetic in which most algorithms are designed. In many domains, roundoff errors are not the only source of inaccuracy and measurement as ...
Inexact hardware design, which advocates trading the accuracy of computations in exchange for significant savings in area, power and/or performance of computing hardware, has received increasing prominence in several error-tolerant application domains, par ...
Carry chains facilitate the implementation of adders and improve the performance of arithmetic circuits in FPGAs. The last version of the commonly used open-source Verilog-to-Routing (VTR) CAD flow now enables modelling carry chains in FPGA architectures. ...
The research aims to investigate one of the controversial chapters in architecture, far from the linear evolution of the internationally nascent "Neues Bauen", that is Swedish National Romanticism through the experience of the leading exponent, Ragnar Östb ...

This paper studies the second-order asymptotics of the Gaussian multiple-access channel with degraded message sets. For a fixed average error probability epsilon is an element of (0, 1) and an arbitrary point on the boundary of the capacity region, we char ...

This paper analyses the short pamphlet -"Ett hem. Dess byggnad och inredning" (Eng. "A Home. Its construction and interior design", 15 pages)- written in 1905 by Swedish architect Ragnar Östberg (1866-1945). It encapsulates the Nordic devotion to craft, in ...
This work concerns a dedicated mixed-signal power system dynamic simulator. The equations that describe the behavior of a power system can be decoupled in a large linear system that is handled by the analog part of the hardware, and a set of differential e ...
Writing accurate numerical software is hard because of many sources of unavoidable uncertainties, including finite numerical precision of implementations. We present a programming model where the user writes a program in a real-valued implementation and sp ...
