A restricted case of the Circuit Value Problem known as the Sequential NOR Circuit Value Problem was recently used to obtain very succinct examples of conjunctive grammars, Boolean grammars and language equations representing P-complete languages (Okhotin, “A simple P-complete problem and its representations by language equations”, MCU 2007). In this paper, a new encoding of the same problem is...

Febrile urinary tract infection is one of the commonest infections in the childhood. Unrecognized and untreated childhood UTI can lead to scarring of the growing kidneys with subsequent hypertension and renal failure. This study has been done at a tertiary care medical centre to study the clinico biological and imaging correlation in children with first episode of febrile UTI. Renal function te...

We describe a novel approach to quantitatively visualize sub nm height changes occurring in thin films of redox active polymers upon reversible electrochemical oxidation/reduction in situ and in real-time with electrochemical imaging ellipsometry (EC-IE). Our approach is based on the utilization of a micro-patterned substrate containing circular patterns of passive (non-redox active) 11-mercapt...

The paper contributes results on the modeling of videoconferencing traffic over IP networks. The study is based on extensive data, gathered by tracing the actual packet exchange during a comprehensive set of realistic teleconferencing sessions over an asymmetric platform, in which commercial H.261-compliant terminal clients were communicating through a Multipoint Control Unit (MCU) at ‘continuo...

This paper addresses the challenges of selecting a suitable method for negative temperature coefficient (NTC) thermistor-based measurement in electronic devices. Although accuracy is great importance, calculation time represents an even greater challenge since it inherently constrained by control algorithm executed microcontroller (MCU). Firstly, simple signal conditioning circuit with NTC ther...
