Database Scalability: An Analytical Comparison of MySQL and PostgreSQL
The burgeoning digital transformation of businesses and the relentless surge of data have placed the onus on databases to be not just repositories but performant systems that can scale on-demand. Scaling is the crucible through which the efficacy of a database is often judged. Let’s explore the intricate world of database scaling, focusing on two…

SegNet: A Deep Convolutional Encoder-Decoder Architecture for Image Segmentation
Semantic segmentation has become a cornerstone in the realm of computer vision, aiming to assign semantic labels to every pixel in an image, facilitating a more granular understanding of the scene. The “SegNet” architecture, as introduced in this paper, is a pioneering deep learning model designed specifically for this task, providing an advanced solution to…

My radio interview “App O Gap”
I have started programming professionally about more than 10 years ago. During the years, I have been working with various teams, companies and startups, meanwhile experiencing the taste of success and failure over and over again. As a matter of fact Success makes me happy, but failure no longer makes me sad. I know that…

My book: Audio file watermarking techniques
In today’s world most of the digital datas are available, but these datas may not have the expected authenticity and this may encounter the users with some problems. One of the ways to verify the authenticity of datas is watermarking . In this way the authenticity can be verified by adding some datas to the…

Brain And Social Networks
Preface Do you know how the brain shapes social networks, or how social relationships form the state of the brain? Social networks are complicated network that publicize the object between the people. The brain consists of networks that processed the information and transfer through neural sections. Whereas the brain functions and the structure of the…

Authentication through Presence in Wireless Networks
This was my very first ISI verified paper that me and Dr Aminian worked on together in 2015. Today i realized that someone had cited to it and i’m so happy that a researcher found it useful and worthy to cite. It would be a pleasure for me if you study it and share your…

The inquiry of instability of Quadcopters in the event of propeller failure
Abstract At first glance, we can say that there are various flying conditions for quadcopters governing. These flying conditions can include altitude, conditions and angles of rotation and safe landing spot and also avoidance of collisions with obstacles and so on. These includes reconfiguring and optimizing energy consumption, estimating flying conditions, and so on. The…

Gyroscope from 0 to 100 (Part 2)
Gyroscope stability According to the equations and studies done at the angular momentum, the angular momentum vector variations of the rigid body in the time interval \(t_i\) to \(t_f\) are calculated as follows. The parameter \(H_f\) represents the angular momentum vector at the final moment of \(t_f\). The angular momentum vector at the initial moment…

Gyroscope from 0 to 100 (Part 1)
In during time in your life, maybe you thought about this question in your mind that why a bicycle falls to the ground in off state without holder column (in stop stage); but the moving bike can keep its balance? Gyroscope physics is one of the hardest concepts in physics that requires a lot of…

Internet of Things (IoT) in Agriculture – Summary
IoT is an environment where objects, animals or people are equipped with unique identifiers capable of data transmission over Internet network without the need for human-human or human-computer interaction (Gluhak et al., 2011). According to Juniper Research (Juniper Research, 2015) over 13,4 billion device were connected to the internet as part of IoT in 2015…

Adaptive Genetic Algorithms Based on Fuzzy Rules
In this post a fuzzy approach to improve the diversity of population in genetic algorithm implementa- tions, based on Mamdani fuzzy rules, with the tuning of crossover and mutation probabilities, is proposed. The necessary steps to implement the adaptive genetic algorithm based on fuzzy rules is outlined, in which the crossover and mutation probabilities are…
