Global Navigation Satellite Systems (GNSS) are the cornerstone of modern navigation and positioning technology. In this paper, we introduce an innovative approach to GNSS signal acquisition, specifically designed to enhance the performance and ...

With fiber-optic seismic acquisition development, continuous dense seismic monitoring is becoming increasingly more accessible. Repurposing fiber cables in telecommunication conduits makes it possible to run seismic studies at low cost, even in ...

• We use fiber-optic cables in telecom conduits to record continuous seismic data.
• We train a neural network to detect small local earthquakes with 93% accuracy.
• We combine fiber-optic and seismometer data to further improve ...

The Global Positioning System (GPS) receivers often encounter noise and interference signals that degrade the receiver performance. The conventional methods for weak signal acquisition fail to work correctly and accurately in all conditions. In ...

Ariba Inc. and Commerce One Inc. (C1), two bellwethers with e-entrepreneurship in the e-commerce field, provided business-to-business (B2B) spend management and supply chain services. After having been wiped out by the devaluation of the stock market ...

Potential threat identification of network communication can improve the reliability of power grid, and an algorithm for potential threat identification of power UAV (Urban Assault Vehicle) network communication is designed. In order to identify ...

The purpose of this study is to prove that the acquiring company performs earnings management by increase the accrual value (income increasing accrual) before the acquisition with the aim of increasing profits and sold so that the costs incurred to make ...

This quasi-experimental study explores the impact of Edmodo application on students’ achievement in language skills and retention in EFL context. Fifty three eleventh grade students participated in this study. A quasi-experimental design was used ...

Lung cancer is a deadly disease if not diagnosed in its early stages. However, early detection of lung cancer is a challenging task due to the shape and size of its nodules. Radiologists use automated tools for more precise opinion. Automated ...

The Characteristics of acquisition and extinction of conditional fear are studied in community prisoners. The influence of state anxiety on conditional fear were also investigated here to understand fear processing in community ...

This paper describes the design and development of field programmable gate arrays based anti-jamming hardware. The key function of the system involves a new post-correlation filtering system to provide an anti-jamming feature in GPS receivers. The ...

Interference has destructive impacts on all signals, but due to the weakness of the global positioning system (GPS) signals, even low-power interference has a significant destructive effect. Mitigation of that effect is a challenging issue for GPS ...

Time-adverbials in English are ambiguous between an occasion-counting reading and an event-counting reading. On the contrary, Mandarin has a rich system of event classifiers that can lexically disambiguate the two readings. The classifier hui ...

This study aims to discover native Mandarin-speaking children’s knowledge and acquisition of the numeral container classifier phrases in Mandarin Chinese. Such phrases are ambiguous and often have two readings. san bei shui ‘three cups of water’ ...

Social coding facilitates the sharing of knowledge in GitHub projects. In particular, issue reports, as an important knowledge in the software development, usually contain relevant information, and can thus be shared and linked in the developers’ ...

In recent years, the widespread growth of mobile-assisted language learning using apps has made English vocabulary learning increasingly accessible. This study investigated students' perceptions of a vocabulary learning app developed by the researcher as ...

Binary offset carrier (BOC) modulated signals are widely utilized in the new generation global navigation satellite system (GNSS), but the multiple peaks of the correlation function result in the ambiguity of acquisition. In this paper,...

The purpose of this paper is to design a low power Global Navigation Satellite System receiver for satellite application based on Particle Swarm Optimization (PSO) algorithm. The receiver processes the satellites signals and provide enough information ...

As the communication center of information battlefield, airborne data chain is developing towards the direction of high speed, large capacity, heterogeneous networking and intelligence. For the forward airborne secure transmission and communications pod,...

Over the last decade, to improve the necessary accuracy and reliability of the existing global positioning system (GPS), incorporation with new constellations such as European Galileo navigation system and the update of the Russian Global Navigation ...

This article describes how physiological signal monitoring plays an important role in identifying the health condition of heart. In recent years, online monitoring and processing of biomedical signals play a major role in accurate clinical diagnosis. ...
