Remote sensing technology which uses laser light to measure distances to objects and surfaces. It is simply emitting laser pulses which bounce off objects and return to sensor. It looks similar isn’t it, Radar also emits bouncing from objects but it uses radio waves, both of them use of TOF idea(Time of Flight) of signal and change in frequency (Doppler shift) to calculate distance, speed, and direction of object. However, there are key differences; Resolution: Lidar has a higher resolution and can provide more detailed information about environment. Range: Lidar can detect o... 2024-08-18T00:00:00+00:00 https://yavuzertugrul.com/asr_research_test This is my first time getting into application side of artificial intelligence, I have been researching/learning about machine learning so far it was mostly related with data science and theoretical part, now I had chance to test some real stuff on real hardware and it is exciting. First of all, I tried to understand what is hugging face and when I browse through pages tabs of it I really got excited because there are a lot of stuff that is open sourced and if I have the hardware to test them I had chance to apply them according to my need and this is really powerful, and how lucky we are t... 2024-08-11T00:00:00+00:00 https://yavuzertugrul.com/deep_live_cam While I was browsing through the repositories of github I saw this deep live cam and it was becoming popular so I wanted to see what stage we are at in this technology, and the best way to do this is to try it by testing etc. rather than researching, so I installed it locally. Installation While I was trying to install it from here I had problems. I recommend you to be strict about following instructions, for example I had 3 different python versions 3.12, 3.11, and 3.9 so I thought python part is fine but when I tried to install required packages/modules I had a lot of problems after I sol... 2024-08-04T00:00:00+00:00 https://yavuzertugrul.com/WSL I have been using WSL for development on Windows for quite some time, and I believe that it is the best possible way to use both Windows and Linux operating systems. Before finding WSL, I used a full Linux setup, dual boot, or other VM software. For example, dual boot was a bit risky for me because once, when I tried to install Ubuntu and Windows together, I accidentally erased the Windows OS. That was painful, and I needed to find a solution for it. After some years, I eventually made a dual boot and used it a lot. However, I created a 50 GB partition from Disk C on my local computer, and ... 2024-04-11T00:00:00+00:00 https://yavuzertugrul.com/Pathfinding-Algorithm-BFS In this post I will talk about pathfinding algorithms, and try to explain how pathfinding works. First I will talk about patfinding algorithms then I will show you Best-first search algorithms and how to implement it on our maze which we will create on pygame. What is Pathfinding? Pathfinding is the computational process of finding a path between two points. It is a fundamental concept in computer science, used in various fields such as robotics, video games, transportation, and network data flow. The goal of pathfinding algorithms is to find the most efficient route from the starting point... 2024-02-19T00:00:00+00:00 https://yavuzertugrul.com/atomik-aliskanliklar-kitap-incelemesi [TR] Atomik Alışkanlıklar — Kitap İncelemesi Herkese selamlar!

These coins are not only currency, but also links to our past. Some may have been used in times of war, others for everyday transactions like buying food, book, clothes or acquiring a new home. Each coin holds a story, a glimpse into the lives and times of those who once held them. My journey as a collector often takes me through antique bazaars, online marketplaces, and networks of fellow ... 2024-01-08T00:00:00+00:00 https://yavuzertugrul.com/web-scraping-part-iii-instagram-github Have you ever felt lost in the endless world of GitHub repositories or puzzled by your Instagram connections?

In 2016, this AI creation from DeepMind achieved what many thought was decades away: it defeated a world champion Go player. This wasn’t merely a victory on the board; it was a demonstration that artificial intelligence could grasp, master, and even innovate in an arena where human intuition had reigned supreme. So, this week I watched AlphaGo — The Movie and it really impressed me, the compa... 2023-11-18T00:00:00+00:00 https://yavuzertugrul.com/HVDC_transmission_system 2023-11-13T00:00:00+00:00 https://yavuzertugrul.com/one-thought-on-the-humane-ai-pin One Thought on the Hu.Ma.Ne AI Pin hu.ma.ne ai pin Technology has profoundly reshaped our lives, transforming from a luxury of the elite to a personal companion nestled within a pin. Gone are the days when data traveled by plane; now, an AI assistant sits discreetly on our lapel.

Machine learning, a pivotal subset of artificial intelligence, revolves around the creation and refinement of algorithms that can learn and make inferences or predictions from data without being directly programmed for specific tasks. As an integral part of both AI and computer science, it mimics human learning processes by using data and algorithms to progressively enhance its precision. This capability allows machines to gain insights or make decisions autonomously, a trait central to its nature as a branch of artificial intelli... 2023-10-30T00:00:00+00:00 https://yavuzertugrul.com/Control_System_for_Electric_Vehicle_Motor 2023-10-24T00:00:00+00:00 https://yavuzertugrul.com/Power_Electronics_Simulations 1) In the given single-phase half wave rectifier circuit, the load current i0=Ia ​is assumed to be constant, with a very large load inductance (L) chosen by your selection, operating at a frequency of 50 Hz. (a) Simulation for α = 90°: For α = 90°, the load voltage waveform v0 ​can be simulated. Considering R = 10 Ω, the average value Vdc ​of the load voltage waveform can be calculated based on the obtained graphs. This simulation allows us to observe the output voltage under these specific conditions. Theoretical calculations can also be performed to verify the results obtained from the si...
