METROSYST reveals the invisible systems behind every metro vehicle — the power, control, and intelligence that keep a city moving. Written by engineer Sinan Balcı, this book turns complex rail technology into clear, visual, and practical insight. From traction to TCMS, GoA4 to RAMS — understand what every metro hides, and every engineer should know.

A model that wins on MAPE can lose money on the shelf. A 15% accuracy gain can hide a 12% bias. An interval that looks tight can be wrong a third of the time.Forecast metrics are decision instruments, not neutral truth detectors — and most teams are still choosing them by habit. This book shows where MAE, MAPE, sMAPE, WAPE, MASE, RMSSE, CRPS, pinball loss, energy scores, bias measures and cost-based metrics help, and where they quietly mislead.Twelve chapters take you from elicitation and baselines through intermittent demand, probabilistic and hierarchical scoring, and the accuracy–utility gap, to a production evaluation system with monitoring, drift detection, alerting and governance. Every metric arrives with its assumptions, every criticism carries a remedy, and a retrospective Walmart M5 case study runs throughout, with Python listings and reproducibility checks.For demand planners, forecasting data scientists, ML engineers and analytics leads who need evaluation choices they can defend. Measure what matters.

Updated, useful reference for those involved in plant design, covering all aspects of plant layout in broad detail

My first book “An Applied Guide to Process and Plant Design” showed academics, current students and recent graduates what process plant design is really about. It explains the basis of process plant design, its methodology, and application. It is the book which I wish I had been able to buy when I was learning to be a process engineer.

Hard work is one of the most misused words, people in the middle or lower economic classes often get it confused with the term “work hard”. Working hard means working for a longer duration whose economic value is lower, but hard work means working which requires expertise, has demand, and thus, has higher economic value. The advantage of hard work is that one can gather more money even after working for less duration, and the disadvantage of working hard is that even with a longer duration, one will still struggle with the money aspects of life.
