Adaptive array antennas and switched beam array antennas have become core components in future mobile networks. Adaptive arrays can steer beams in any direction of interest while nulling interfering signals, allowing them to track and locate signals. Switched beam arrays have several fixed beam patterns and must decide which beam to access at any given time, with the overall goal of increasing gain based on the user's location.
This ppt is about Smart Antenna which includes history, Introduction, Working of smart antenna and where this smart antennas can be used.This ppt also tells about the types of smart antenna and the main principle of working of smart antenna. Smart antennas mainly categorized as Adaptive and switched beam array.Among these two adaptive antenna is used for the efficient utilisation of frequency spectrum.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

Vaccine management system project report documentation..pdfKamal Acharya
The Division of Vaccine and Immunization is facing increasing difficulty monitoring vaccines and other commodities distribution once they have been distributed from the national stores. With the introduction of new vaccines, more challenges have been anticipated with this additions posing serious threat to the already over strained vaccine supply chain system in Kenya.
3. Has become a core system component in future
generation mobile networks.
Adaptive array allow the antenna to steer the beam to
any direction of interest while simultaneously nulling
interfering signals.
This antennas can track and locate signals.
6. They have several available fixed beam patterns.
Decision has to be made which beam has to be access
at any given point of time.
Overall goal of the switched beam system is to increase
gain according to the location of user.
