In the last twenty years many features of Saaty's Analytical Hierarchy Process (AHP) have been criticised, especially the additive hierarchical composition of conventional AHP, which leads to the possibility of occurrence of the Rank Reversal phenomenon (adding an irrelevant alternative may cause a reversal in the ranking at the top). In the context of a variable number of alternatives this ran...

We propose a new technique to enhance the characteristics of CMOS/SET hybrid multi-valued logic (MVL) circuits in terms of their stability and performance. A complementary self-biasing method enables the SET/CMOS logic to operate perfectly well at high temperature in which the peak-to-valley current ratio of Coulomb oscillation severely decreases. The suggested scheme is evaluated by SPICE simu...

This paper provides an analytical examination of the INFOMAX algorithm and establishes its effectiveness for blind signal separation using extensive simulation results. Results obtained show that the INFOMAX is not able to separate signal sources unless signal pre-processing is carried-out whereby the data to train the separating matrix is decorrelated. Further, results also show that if one us...

A Wireless body area network (WBAN) is a communication network that provides both medical and consumer electronics services by using sensors in/on/around a human body. In general, a WBAN environment suffers from frequent link loss due to interferences among sensors scattered over a body. In addition, the channel condition can frequently change by postural body movement, which increases packet d...

A microfluidic device based on a pair of slant-finger interdigital transducers (SFITs) is developed to achieve a selective and flexible manipulation of microbubbles (MBs) by surface acoustic waves (SAWs). The resonance frequency of SAWs generated by the SFITs depends on the location of its parallel pathway; the particles at different locations of the SAWs' pathway can be controlled selectively ...

Recent technological advances in cutting-edge ultrasensitive fluorescence microscopy have allowed single-molecule imaging experiments in living cells across all three domains of life to become commonplace. Single-molecule live-cell data is typically obtained in a low signal-to-noise ratio (SNR) regime sometimes only marginally in excess of 1, in which a combination of detector shot noise, sub-o...

[1] In the paper ‘‘Experimental evidence for statistical scaling and intermittency in sediment transport rates’’ by A. Singh et al. (Journal of Geophysical Research, 114, F01025, doi:10.1029/2007JF000963, 2009), we performed a multiscale analysis of bed load sediment transport series collected in a large-scale experimental flume at the St. Anthony Falls Laboratory at the University of Minnesota...

S. Bruce, A. Trasser, M. Birk, A. Rydberg and H. Schumacher. Uppsala University, Box 534, S-751 21 Uppsala, Sweden. University of Ulm, Abt. EBS, D-89069 Ulm, Germany. Abstract A novel method for finding the thermal time constant of HBTs is proposed. It utilizes small signal measurements in the frequency domain of the typical negative differential resistance found in the active region, i.e., nor...

Microfluidic sensing platforms facilitate parallel, low sample volume detection using various optical signal transduction mechanisms. Herein, we introduce a simple mixing microfluidic device, enabling serial dilution of introduced analyte solution that terminates in five discrete sensing elements. We demonstrate the utility of this device with on-chip fluorescence and surface-enhanced Raman sca...

The aim of the present editorial is to briefly summarize the current scientific and technological accomplishments in the field of organic electronic biosensors as described in the articles published in this Special Issue. By definition, a biosensor is a robust analytical device that combines a biological recognition element (e.g., antibodies, enzymes, cells) with a transducer. Organic electroni...
