A large part of small-sized UAVs that are used for surface scanning, video- and photography, or other similar applications the multirotor type. These small aircraft perform mainly in hovering nearly flight mode, endurance these vehicles depends greatly on efficiency their motors aerodynamic thrust-generating systems, including propellers, ducted fans, etc. Propellers may therefore work differen...

climatechange and the subsequent requirements to comply with environmental standards, continuoustechnological change, need adapt it, adjust, remain competitive. The COVID-19 pandemic economic hardship it brought about, followed by current energy crisis,make imperative address issues of competitiveness efficiency farm units. Theseunfavorable developments particularly affect mountainous disadvant...

We propose a block motion estimation (ME) algorithm that meets high quality requirements and allows for cost efficient VLSI realizations. It relies on a set of rules common to all recent fast BMA algorithms and has been designed in order to allow for easy and prolific data reuse.

In the conventional Bag-of-Features (BoF) model for image classification, handcrafted descriptors such as SIFT are used for local patch description. Since SIFT is not flipping invariant, left-right flipping operation on images might harm the classification accuracy. To deal with, some algorithms augmented the training and testing datasets with flipped image copies. These models produce better c...

MIMO-OFDM performs signal detection on a subcarrier basis which requires high speed computation in MIMO detection due to its large computational cost. Conventional designs in a MIMO detector increase processing time in proportion to the number of subcarriers and have difficulty in real-time processing for large numbers of subcarriers. A complete pipeline MMSE MIMO detector presented in our prev...

Accurate cropland maps at the global and local scales are crucial for scientists, government and nongovernment agencies, farmers and other stakeholders, particularly in food-insecure regions, such as Sub-Saharan Africa. In this study, we aim to qualify the crop classes of the MODIS Land Cover Product (LCP) in Sub-Saharan Africa using FAO (Food and Agricultural Organisation) and AGRHYMET (AGRicu...

The OTIS-Network (also referred to as two-level swapped network) is composed of n clones of an n-node original network constituting its clusters. It has received much attention due to its many favorable properties such as high degree of scalability, regularity, modularity, package-ability and high degree of algorithmic efficiency. In this paper, using the construction method, we show that the O...
