Optimal control, Fourier transform, operating system, multimedia and w

[iii]

I have a lot of questions, if you know something in one of them or more I will glad if you can write a replay
I search after researches or others things that are correlated between optimal control and autonomous vehicles it can be things like how to calculate the shortest way, the rapid way, the way that use lowest fuel, the optimal velocities, the optimal accelerations, motion planning or others things.
What is the connection between the simples Fourier transforms in Digital Signal Processing and the Fourier transforms in speech recognition?
I search information about the operating systems in cars
I search after information about research or projects that do that the window of the car become a touch screen that the children in the car can play with this.
I search after information about how the video (talk and see) communication work how on internet.
What are the different between cars communications and cellular phones communications that communicate with internet?
I search information about things that are related to control other things in home or in the office by the cellular phone​

Your thread history is in large part a collection of these types of posts where you mainly just list topics that are of interest to you instead of questions that have meaningful answers, e.g.:

I search information about the operating systems in cars.​

You have to realize that whatever response you get, if any, will be extremely general and you could probably do a lot better if you put in some work studying it yourself so you'd have something specific to ask about.

This forum could be much more helpful to you if you tried to narrow down your questions as much as possible.

Edit:
Also, it might be a good idea to limit the scope of the threads you create, i.e. try to keep each thread about something specific within some area so the discussion can be more structured. It's usually a bit tiresome to read if there's several discussions going on in the same thread.

I can provide some information on the topics mentioned. Optimal control is a technique used in control theory to determine the best input to a system in order to achieve a desired outcome. In the context of autonomous vehicles, optimal control can be used to calculate the most efficient route, considering factors such as distance, traffic, and fuel consumption. It can also be used to determine the optimal velocities and accelerations for the vehicle to minimize energy consumption and ensure safe and smooth driving.

Fourier transform is a mathematical tool used to analyze signals and data in the frequency domain. In digital signal processing, Fourier transforms are used to convert a signal from the time domain to the frequency domain, allowing for easier analysis and processing. In speech recognition, Fourier transforms are used to extract features from speech signals, which are then used to identify and recognize words.

In terms of operating systems in cars, there are various systems used in different vehicles. Some cars use proprietary operating systems developed by the manufacturer, while others may use a modified version of a popular operating system like Android or Linux. These operating systems are responsible for controlling and managing various functions in the car, such as navigation, entertainment, and communication.

Regarding the touch screen window for children in cars, there are some research projects and prototypes that exist. One example is the "Windows of Opportunity" project by the University of St. Andrews, which aims to turn the car windows into interactive displays for children to play games and learn during long car rides.

Video communication on the internet uses various technologies such as video codecs, streaming protocols, and network infrastructure to enable real-time communication between users. These technologies work together to compress, transmit, and decompress video and audio data, allowing for smooth communication over the internet.

The main difference between cars and cellular phones in terms of communication is the network infrastructure. Cars usually use dedicated short-range communication (DSRC) systems, while cellular phones use cellular networks. DSRC systems are specifically designed for communication between vehicles and infrastructure, while cellular networks are designed for communication between mobile devices and the internet.

Finally, controlling home or office devices using a cellular phone is possible through the use of smart home automation systems. These systems use wireless communication protocols to connect devices to a central control hub, which can then be accessed and controlled through a mobile app. This allows for remote control and management of various devices, such as lights, thermostats, and security systems.
