Study on the effect of the substrate material type and thickness on the performance of the filtering antenna design [PDF]

, 2020
This article presents a new design of a four-pole microstrip filtering antenna. The filtering antenna consists of a bandpass filter, which has four resonators integrated to a monopole patch antenna.

A resistivity survey of phosphate deposits containing hardpan pockets in Oulad Abdoun, Morocco [PDF]

Geofísica Internacional, 2006
In the great Oulad Abdoun Basin exploitation of a new phosphate deposit was begun after the Grand Daoui horizon was exhausted. Inclusions of sterile hardpan—so-called “disturbances” —are hard to detect and interfere with phosphate extraction.

Local refinement mechanism for improved plant leaf segmentation in cluttered backgrounds

Frontiers in Plant Science, 2023
Plant phenotyping is a critical field in agriculture, aiming to understand crop growth under specific conditions. Recent research uses images to describe plant characteristics by detecting visual information within organs such as leaves, flowers, stems ...

The Nature and Problems of Cyberspace Filtering according to Islamic Jurisprudence [PDF]

Religion & Communication, 2016
One of the inhibiting policies of the government at national levels for creating a healthy cyberspace environment is its filtering. Iran is no exception in this regard and we witness occasional news about censorship ensued by for and against reactions in

Working memory management and predicted utility

Frontiers in Behavioral Neuroscience, 2013
Given the limited capacity of working memory (WM), its resources should be allocated strategically. One strategy is filtering, whereby access to WM is granted preferentially to items with the greatest utility.

Pansharpening Low-Altitude Multispectral Images of Potato Plants Using a Generative Adversarial Network

Remote Sensing
Image preprocessing and fusion are commonly used for enhancing remote-sensing images, but the resulting images often lack useful spatial features. As the majority of research on image fusion has concentrated on the satellite domain, the image-fusion task

Filtered PID Control Loop for Third Order Plants With Delay: Dominant Pole Placement Approach

IEEE Access, 2021
The paper deals with tuning the filtered PID controller applied to third order plants with delay. This model option is chosen as a representative case where the loop characteristic quasi-polynomial is of higher order than three.

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...
