Remote sensing of environment research has explored the benefits of using synthetic aperture radar imagery systems for a wide range of land and marine applications since these systems are not affected by weather conditions and therefore are operable both daytime and nighttime. The design of image processing techniques for  synthetic aperture radar applications requires tests and validation on real and synthetic images. The GRSS benchmark database supports the desing and analysis of algorithms to deal with SAR and PolSAR data.

The distributed generation, along with the deregulation of the Smart Grid, have created a great concern on Power Quality (PQ), as it has a direct impact on utilities and customers, as well as effects on the sinusoidal signal of the power line. The a priori unknown features of the distributed energy resources (DER) introduce non-linear behaviours in loads associated to a variety of PQ disturbances.

The (CSV) table DataSet contains the aggregate results of the 16000 following simulation cases, defined by the first ten columns:

A) ID: # case identifier

B) n=10,20,40,80,160 # number of robots

C) S2M=0,0.5 # Stall-to-Maximum, 0 for differential-drive and quadrotor-like robots, 0.5 for fUAV-like robots

D) PF=0.25,0.5,0.75,1 # Prudence Factor, max. velocity is PF*r/s (+/- 10%), where r is the communication factor, and s is one second

E) OF=1,2 # Overpopulation Factor

F) T=0.25,0.5,0.75,1 # high-level control period (+/- 10%)

Given the non-cooperative relationship between the transmitter and the jammer, two main challenges are addressed in this paper: how to model their interactions and how to devise a jamming strategy without prior knowledge of the transmitter. A non-zero-sum game is used to model and analyze such non-cooperative interactions. An approximate mixed-strategy Nash equilibrium (NE) under complete information is derived to serve as a benchmark for comparison.

The REST (REpresentational State Transfer) paradigm has become essential for designing distributed applications that leverage the HTTP protocol, enabling efficient data exchange and the development of scalable architectures such as microservices. However, selecting an appropriate framework among the myriad available options, especially given the diversity of emerging execution environments, presents a significant challenge. Often, this decision neglects crucial factors such as performance and energy efficiency, favoring instead developer familiarity and popularity within the industry.

Most existing graph keyword search works assume that the graph data is complete and clean, that is, there are no missing information (such as keywords or edges) and contaminated information (such as keywords) on the graph. However, real-world graphs often suffer from missing or being contaminated, making the keyword search on graphs much more challenging. We provide this dataset for the keyword search on dirty graphs.

We investigated whether thinking in opposites can facilitate the solution process in Wason’s rule discovery task. Participants were exposed to three conditions: training prompting an analysis of the properties characterising the initial seed triple; training prompting the same action but subsequently demanding the identification of the opposites of each property and using it in the testing phase; and a no-prompt condition. Thinking in opposites turned out to be beneficial, almost doubling success rate.

Computer experiment is crucial for marine controlled-source electromagnetic (CSEM) forward modeling in hydrocarbon exploration. Marine CSEM computer experiment is used to discretize the governing equations of the electromagnetic (EM) fields. One dimensional (1D) simulation usually is fully utilized to determine the reliability of the higher dimensional marine CSEM computations. All the data were generated using Web Hosted Active-Source Modeling (WHAM) online resource.

The study investigates the relationship between people’s personality and the types of hats they like and would be willing to wear. The question is of interest for the psychology of personality and aesthetic preferences, empirical aesthetics, and potentially also for marketing studies. 539 Italian adults completed an on-line questionnaire showing black and white images of 34 iconic types of hat (set 1) and 8 types of baseball caps (set 2) one at a time. For each hat, they were asked to rate how much they liked it and how likely it was that they would wear it.
