Performance analysis of one-step prediction-based cognitive jamming in jammer-radar countermeasure model

open access: yesThe Journal of Engineering, 2019
Strong adaptive radar, such as cognitive radar (CNR), can perform various missions while ensuring its own security in electronic warfare, via detecting environments and changing the radar parameters in real time.

Classification of Incomplete Data Using the Fuzzy ARTMAP Neural Network [PDF]

open access: yes, 2000
The fuzzy ARTMAP neural network is used to classify data that is incomplete in one or more ways. These include a limited number of training cases, missing components, missing class labels, and missing classes.

Leading the Loop: Anchor‐Led Orchestration in Nascent Circular Ecosystems—A Qualitative Case Study

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The transition towards a circular economy necessitates coordinated, systemic change across value chains. Yet the role of anchor firms in initiating and orchestrating nascent circular ecosystems remains underexplored. Using an inductive, qualitative single‐case design, we analyse a German mid‐sized entrepreneurial firm, drawing on 21 interviews

A Neural Network Architecture for Figure-ground Separation of Connected Scenic Figures [PDF]

open access: yes, 1991
A neural network model, called an FBF network, is proposed for automatic parallel separation of multiple image figures from each other and their backgrounds in noisy grayscale or multi-colored images.

Connecting Thoughts and Actions: A Managerial Process Model on Circular Business Model Innovation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Addressing environmental grand challenges such as resource scarcity requires circular business model innovation (CBMI) that enables firms to efficiently close and slow resource cycles through novel activity systems. Drawing on a grounded theory approach based on 59 in‐depth interviews with top managers from Swiss SMEs, we developed a process ...

The Tree of Life Synagogue Attack: A Terrorist Radicalization Assessment Protocol‐18 Examination of Pre‐Attack Warnings and Post‐Attack Contagion and Copycat Effects

open access: yesBehavioral Sciences &the Law, EarlyView.
ABSTRACT This is a retrospective case study of an antisemitic lone actor terrorist who completed the deadliest attack against the Jewish community in American history. The analysis through the lens of the Terrorist Radicalization Assessment Protocol (TRAP‐18) finds that 72% of the warning indicators were present, including four proximal warning ...

Memory‐augmented cognitive radar for obstacle avoidance using nearest steering vector search

open access: yesIET Radar, Sonar & Navigation, 2021
This study describes a cognitive radar architecture with application to real‐time obstacle avoidance in mobile robotic platforms. The concept of a world memory map is introduced as a means of providing an enhanced perception of the environment around the

Strategy Constancy Amidst Implementation Differences: Interaction-Intensive Versus Memory-Intensive Adaptations To Information Access In Decision-Making [PDF]

open access: yes, 2004
Over the last two decades attempts to quantify decision-making have established that, under a wide range of conditions, people trade-off effectiveness for efficiency in the strategies they adopt.

Interfacial Solvent Molecular Engineering via High‐Safety Dense Separators for High‐Rate Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The dense PPS‐separator prevents thermal runaway by allowing electron transfer through the steel needle during penetration, while the residual electrolyte enables brief ion migration and Joule heating, causing rapid electrolyte vaporization, collapse of the ion transport network, and a sharp drop in ionic conductivity.
