HelexKids:a word frequency database for Greek and Cypriot primary school children [PDF]

, 2016
In this article, we introduce HelexKids, an online written-word database for Greek-speaking children in primary education (Grades 1 to 6). The database is organized on a grade-by-grade basis,and on a cumulative basis by combining Grade 1 with Grades 2 to

Impact of forest fire frequency on floristic diversity in the forests of Uttarakhand, western Himalaya

Trees, Forests and People, 2022
The Uttarakhand State of India is rich in forest wealth with 45.4% forest cover (India State of Forest Report (2021). However, forest cover may change due to a number of anthropogenic and environmental factors.

Noncoherent Multi-Way Relay Based on Fast Frequency-Hopping M-ary Frequency-Shift Keying [PDF]

, 2010
Information exchange among a group of users is implemented with the aid of fast frequency-hopping $M$-ary frequency-shift keying multi-way relay (FFH/MFSK MWR). The FFH/MFSK MWR scheme uses two time-slots per symbol for achieving the information exchange,

Virtual Antenna Arrays with Frequency Diversity for Radar Systems in Fifth-Generation Flying Ad Hoc Networks

Applied Sciences
This paper proposes the design of virtual antenna arrays with frequency diversity for radar systems in fifth-generation flying ad hoc networks. These virtual arrays permit us to detect targets from the sky with flying drones.

Space scanning FMCW-based two-dimensional frequency diverse array radar

The Journal of Engineering, 2019
The frequency-modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is extended to two dimensions (2D). The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as a pulsed FMCW/phased ...

Contextual diversity, not word frequency, determines word-naming and lexical decision times [PDF]

Word frequency is an important predictor of word-naming and lexical decision times. It is, however, confounded with contextual diversity, the number of contexts in which a word has been seen.

Modeling lexical decision : the form of frequency and diversity effects [PDF]

What is the root cause of word frequency effects on lexical decision times? W. S. Murray and K. I. Forster (2004) argued that such effects are linear in rank frequency, consistent with a serial search model of lexical access. In this article, the authors

Cost effective estimation and equalization of frequency selective channels for transmit diversity [PDF]

, 2011
In this paper we propose a novel receiver for multiple input single output channels. Such approaches are preferred in boosting the diversity within the channel, to combat fading.
