Compact low-voltage power-efficient operational amplifiers are described that are very suitable as very-largescale-integration library cells because of the small die area of 0.08 mm and the minimum supply voltage of 1.8 V. A key part of the circuit is the rail-to-rail class-AB output stage with folded mesh feedback control that combines power efficiency with operation down to 1.8 V and allows s...

Liberalisation process has just started in the Turkish rail market with the new law recently entered into force in order to comply with EU Directives. In the liberalised markets, service quality is the decisive factor that rail undertakings can use to create difference and achieve competitive advantages. The purpose of this paper is to analyse the customer perceived service quality for rail fre...

An overall objective of the REORIENT project is to develop a business case for a new rail service between the Nordic countries and countries in Centraland South Eastern Europe. We developed, conducted, and used information from a survey conducted by the REORIENT project among intermodal freight shippers in countries within the REORIENT Corridor to identify essential factors for attracting freig...

Railway transport is a type of transport which is commonly used today. Rail line must be robust due to the heavy structure of the railway vehicles. Components constituting the rail line are very important to prevent the disruption of transportation. In this study, faults are determined by monitoring the rail and fastening components constituting the railway. Test vehicle was used to get experim...

A novel design method of asynchronous domino logic pipeline, which focuses on improving the circuit efficiency and making asynchronous domino logic pipeline design more practical for a wide range of applications. The data paths are composed of a mixture of dual-rail and single-rail domino gates. Dual-rail domino gates are limited to construct a stable critical data path. Based on this critical ...

This project presents a high-throughput and ultralowpower asynchronous domino logic pipeline design method, targeting to latch-free and extremely fine-grain or gate-level design. The data paths are composed of a mixture of dual-rail and single-rail domino gates. Dual-rail domino gates are limited to construct a stable critical data path. Based on this critical data path, the handshake circuits ...

Dual-rail encoding, return-to-spacer protocol and hazard-free logic can be used to resist power analysis attacks by making energy consumed per clock cycle independent of processed data. Standard dual-rail logic uses a protocol with a single spacer, e.g. all-zeroes, which gives rise to energy balancing problems. We address these problems by incorporating two spacers; the spacers alternate betwee...

The evaluation of trial operation of urban rail transit is a decisive link of whether the new line of urban rail transit can put into trial operation. Whether the result of evaluation is objective, reasonable and effective has a direct relation with whether urban rail transit can ensure operation safety and satisfy the basic service requirements. Therefore, it is very important to make sure tha...
