Does the use of nest materials in a ground-nesting bird result from a compromise between the risk of egg overheating and camouflage?
(Company of Biologists, 2019)
Many studies addressing the use of nest materials by animals have focused on only one factor to explain its function. However, the consideration of more than one factor could explain the apparently maladaptive choice of ...

Domino inspired MOBILE networks
(Institute of Electrical and Electronics Engineers, 2012)
MOBILE networks can be operated in a gate-level pipelined fashion allowing high through-output. If MOBILE gates are directly chained, a four-phase clock scheme is required. A single phase scheme has been recently reported ...

Design issues and experimental characterization of a continuously-tuned adaptive CMOS LNA
(2010)
This paper presents the design implementation and experimental characterization of an adaptive Low Noise Amplifier (LNA) intended for multi-standard Radio Frequency (RF) wireless transceivers. The circuit —fabricated in a ...

Post-quantum biometric authentication based on homomorphic encryption and classic McEliece
(MDPI, 2023-01)
Homomorphic encryption is a powerful mechanism that allows sensitive data, such as biometric data, to be compared in a protected way, revealing only the comparison result when the private key is known. This is very useful ...

Non-Fungible Tokens Based on ERC-4519 for the Rental of Smart Homes
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
The rental of houses is a common economic activity. However, there are many inconveniences that arise when renting a property. The lack of trust between the landlord and the tenant due to fraud or squatters makes it necessary ...

Experimental Characterization of IdleTones in Second-Order Bandpass ΣΔ Modulators
(2000)
This paper analyses the tonal behaviour of the quantization noise in second-order bandpass ΣΔ modulators. The analysis performed for lowpass modulators is extended to the bandpass case. As a result, closed form expressions ...

Predictive Cell Culture Time Evolution Based on Electric Models
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Obtaining cell concentration measurements from a culture assay by using bioimpedance is a very useful method that can be used to translate impedances to cell concentration values. The purpose of this study was to find a ...

A 32 x 32 Pixel Convolution Processor Chip for Address Event Vision Sensors With 155 ns Event Latency and 20 Meps Throughput
(IEEE Computer Society, 2011)
This paper describes a convolution chip for event-driven vision sensing and processing systems. As opposed to conventional frame-constraint vision systems, in event-driven vision there is no need for frames. In frame-free ...

Form Factor Improvement of Smart-Pixels for Vision Sensors through 3-D Vertically- Integrated Technologies
(Institute of Electrical and Electronics Engineers, 2014)
While conventional CMOS active pixel sensors embed only the circuitry required for photo-detection, pixel addressing and voltage buffering, smart pixels incorporate also circuitry for data processing, data storage and ...
