Murat & ZenQ · AI Explorers: How Does AI Think? (Volume 1)Online · Emrah Murat Tekeli · ISBN 978-625-00-6054-4One rainy Saturday, a sparkle rises from an old tablet: ZenQ! A round, helpful and sometimes overconfident AI. Eight-year-old Murat has a first question ready: "But why?" At the "Hello, I'm ZenQ!" stop you hunt for the hidden AIs at home. At "Think Like a Robot!" you give ZenQ a sandwich recipe – if only you knew what it did with the jar! And at "Dog or Cushion?" you work together to fix a machine that mistakes a chubby dog for a cushion. Every stop holds a story, a "What Is This?" box, a screen-free game, a workshop and a badge. Each book can be read on its own. For children aged 7–10 and their parents. Published in Turkish. - Book

Spor Bilimlerinde Veri Analizi [Data Analysis in Sport Sciences]Online · Emrah Murat Tekeli · ISBN 978-625-00-4896-2Sport science is shifting from observation-based methods to measurement- and data-driven approaches. Motion capture systems, force platforms, inertial sensors, electromyography and positional tracking now record human movement at a resolution that was previously out of reach. Yet more data does not by itself produce knowledge: how reliable a measurement is, how the signal is processed and how the result feeds into a training or health decision matter more than the technology itself. In six parts and fifteen chapters, this book covers the chain from the fundamentals of biomechanical and physiological measurement to signal processing, from reliability and validity to statistical inference, and from machine learning to ethics and open science. All computational examples are given in Python, and every chapter includes learning objectives, worked examples, field applications and exercises. Written for students of sport science, physical education and physiotherapy, as well as performance analysts, coaches and researchers. Published in Turkish.
Latest technical notes
All notes →- 3 min readMTBF, MTTR and availability: three numbers, three different questionsMTBF says how often a machine fails, MTTR how quickly it comes back, availability what share of the time the line can produce. We calculate all three from one example, show which decision each one supports, and list the four most common mistakes.
- 3 min readBearing life L10: what it says and what it does not, with load, speed and reliabilityFrom the catalogue dynamic load rating to the basic rating life, then to the reliability and operating-condition adjustment: we calculate a bearing's expected life step by step, show why a small increase in load shortens life so much, and list the questions L10 does not answer.
- 3 min readPareto of downtime causes: 80/20 is not a law, it is a starting pointWe rank one month of downtime records by cause and work out the cumulative share. The example deliberately does not follow 80/20: five of eight causes make up 86.7% of the total. We show how to choose the threshold, how record quality distorts the result, and what comes after Pareto.
- 3 min readThe true cost of unplanned downtime: how to calculate lost hours, repair and the payback of predictive maintenanceThe cost of one stoppage is more than the repair invoice. We walk through lost production hours, repair and a realistic estimate of what early warning saves in one worked example, and show which assumption moves the result most.
