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...

In view of the problems present in construction process embedded track structure modern tram, we have designed a Novel Fastener Type Ballastless Track (NFTBT) for tram. To optimize size NFTBT’s structure, finite element model tram running stage is built, mechanical characteristics are calculated, and geometric parameters systematically studied. The research results as follows: (1) As slab incre...

OBJECTIVE To evaluate mandibular irregularity index stability following orthodontic treatment facilitated by alveolar corticotomy and augmentation bone grafting (Cort+). MATERIALS AND METHODS The irregularity index of 121 orthodontically treated and 15 untreated patient study casts was analyzed at 5 years and 10 years. RESULTS Cort+ resulted in significantly lower mandibular irregularity in...

The propagation of shear waves differs between geo-media due to layer’s structure and irregularity present in different layers. This paper studies the propagation of shear waves in a monoclinic layer with irregularity lying between two isotropic semiinfinite elastic medium. The displacement in the monoclinic layer is obtained by using perturbation technique. Then the dispersion relation is foun...

The article discusses the issues of building intelligent receivers pulsed signals with an unknown arrival time without restrictions on value signal-to-noise ratio under influence a complex interfering factors. Using recurrent methods for detecting disturbances random processes and algorithm cumulative sums, problem synthesizing algorithms Markov moments appearance against background various com...

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 ...
