Supply Chain Sustainability and Human Capital: A Multilevel Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how corporate sustainability practices diffuse across global supply chains and how national contextual capacity shapes this process. Drawing on stakeholder and institutional perspectives, we conceptualize ESG transmission as relational and potentially asymmetric between customers and suppliers.

Do Banks in the Middle East and North Africa Region Price Carbon Exposure?

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether carbon exposure is incorporated into corporate borrowing costs within the Middle East and North Africa (MENA) region. Using a panel of 771 firm‐year observations from publicly listed non‐financial firms between 2016 and 2023, the analysis investigates the relationship between carbon intensity and firms' cost of debt

The Heat Is On: Climate Change–Related Challenges and SMEs' R&D Activities

Business Strategy and the Environment, EarlyView.
ABSTRACT Investing in R&D is a key way for small‐ and medium‐sized enterprises (SMEs) to develop capabilities that are required to respond to climate change–related challenges. However, the extent to which such challenges affect SMEs' R&D activities remains a critical gap in the literature.

Usage of Costas arrays in Low Probability of Intercept radars

2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015
Low Probability of Intercept (LPI) radars are used to detect targets at low distances by means of coded signals without being intercepted by hostile elements. Frequency Shift Keying (FSK) is one of the signal types used by LPI radars. In LPI radars, the frequency sets of FSK signals, which are constructed with continuous wave, are obtained by using ...

Detection of low probability of intercept signals in low SNR using multichannel sensor arrays

2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
In this paper, a method is proposed for the detection of low probability of intercept, LPI signals in high noise without prior knowledge and assumption using spatially distributed multichannel wideband sensor array. The proposed detection method uses eigenvalue ratios (EVR) of wideband spatial covariance matrix as test statistic.

Automated and Blind Detection of Low Probability of Intercept RF Anomaly Signals

Proceedings of the 30th Annual International Conference on Mobile Computing and Networking
Automated spectrum monitoring necessitates the accurate detection of low probability of intercept (LPI) radio frequency (RF) anomaly signals to identify unwanted interference in wireless networks. However, detecting these unforeseen low-power RF signals is fundamentally challenging due to the scarcity of labeled RF anomaly data.

Low Probability of Intercept Waveform Optimization Method for Sar Imaging

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The survivability and stability of synthetic aperture radar (SAR) in the increasingly severe electromagnetic environment are widely concerned. With the development of interception receiver technology, it is very difficult to prevent the competitor from detecting the radio frequency (RF) energy of radar.

A study on the feasibility of low probability of intercept sonar

2009 43rd Annual Conference on Information Sciences and Systems, 2009
We explore the feasibility of low probability of intercept for sonar signals. Using a noise-like active sonar signal, the transmitter (platform) employs a matched filter for echo detection while the target is assumed to use an energy detector. Decision statistic distributions are developed at both the platform and target.

The metrication of low probability of intercept waveforms

2010 International Waveform Diversity and Design Conference, 2010
In recent years, military radar operators have been concerned that the transmitted radar signals will beacon the presence of the radar to an enemy. If intercepted, the radar signals alert a target to an attack which could prompt evasive measures or countermeasures to be taken by the target including the possibility of a reprisal attack using an ...
