Keywords: autonomous driving, neural network control, slot car, intelligent vehicle.
Abstract. Intelligent vehicle is an attractive solution to the traffic problems caused by automobiles.
An experimental autonomous driving system based on a slot car set is designed and realized in the
paper. With the application of a wireless camera equipped on the slot car, the track information is
acquired and sent to the controlling computer. A backpropogation (BP) neural network controller is
built to imitate the way of player’s thinking. After being trained, the neural network controller can
give the proper voltage instructions to the direct current (DC) motor of the slot car according to
different track conditions. Test results prove that the development of the autonomous driving
system is successful.
Introduction
Autonomous driving is a very important researching field of the ITS (Intelligent Transportation
Systems). It means that no participation of the driver is required while driving. After decades of
efforts, great progress has been made to advance the reliability and security of autonomous driving.
It is reported that four driverless vehicles drove successfully over 13,000 km from Italy to China as
an attempt to test the feasibility of autonomous driving in 2010 in the VIAC Challenge (The VisLab
Intercontinental Autonomous Challenge) [1].
In this paper, an experimental autonomous driving based on a slot car set is designed and
realized. The slot car used to be operated through a joystick by the player, but here it is fully
controlled by a computer. That is to say, the control computer is applied to imitate the player’s way
of thinking; it can finally give the correct instruction to the slot car according to different track
conditions. The general goal of the experiment is that, on the premise of safe driving, the slot car
controlled by the computer can finish the race in a time as short as possible. To achieve this goal, a
neural network controller is built in the computer to imitate the player’s way of thinking.

The diac is a bidirectional thyristor that can be switched from an off state to an on state with either polarity of applied voltage. It has two terminals, like a triac but without a gate, and consists of five layers. In its off state, only a small leakage current flows until the breakover voltage is reached, at which point avalanche breakdown occurs and the device exhibits negative resistance, with current increasing as voltage decreases down to the breakback level.
UNIT4.pptx
- The document discusses various types of special semiconductor devices including Schottky barrier diodes, varactor diodes, tunnel diodes, and LDRs.
- A Schottky barrier diode forms a junction between a metal and a semiconductor. It has lower forward voltage drop than a PN junction diode. Varactor diodes are used for tuning as their capacitance varies with reverse bias voltage.
- Tunnel diodes have a very thin depletion region due to high doping. They exhibit negative resistance where current decreases with increasing forward voltage between the peak and valley points. LDRs have resistance inversely proportional to light intensity.

Abstract: Fuzzy Logic Controller (FLC) systems have emerged as one of the most promising areas for Industrial Applications. The highly growth of fuzzy logic applications led to the need of finding efficient way to hardware implementation. Field Programmable Gate Array (FPGA) is the most important tool for hardware implementation due to low consumption of energy, high speed of operation and large capacity of data storage. In this paper, instead of an introduction to fuzzy logic control methodology, we have demonstrated the implementation of a FLC through the use of the Very high speed integrated circuits Hardware Description Language (VHDL) code. FLC is designed for position control of BLDC Motor. VHDL has been used to develop FLC on FPGA. A Mamdani type FLC structure has been used to obtain the controller output. The controller algorithm developed synthesized, simulated and implemented on FPGA Spartan 3E board. Keywords – BLDC Motor, FLC, Hardware Implementation, Spartan3 FPGA, VHDL

The diac is a bidirectional thyristor that can be switched from an off state to an on state with either polarity of applied voltage. It has two terminals, like a triac but without a gate, and consists of five layers. In its off state, only a small leakage current flows until the breakover voltage is reached, at which point avalanche breakdown occurs and the device exhibits negative resistance, with current increasing as voltage decreases down to the breakback level.
UNIT4.pptx
- The document discusses various types of special semiconductor devices including Schottky barrier diodes, varactor diodes, tunnel diodes, and LDRs.
- A Schottky barrier diode forms a junction between a metal and a semiconductor. It has lower forward voltage drop than a PN junction diode. Varactor diodes are used for tuning as their capacitance varies with reverse bias voltage.
- Tunnel diodes have a very thin depletion region due to high doping. They exhibit negative resistance where current decreases with increasing forward voltage between the peak and valley points. LDRs have resistance inversely proportional to light intensity.

A JFET is a voltage-controlled transistor that uses an electric field to control the flow of current through a channel. It has three terminals - the gate, source, and drain. In an N-channel JFET, applying a negative voltage to the gate depletes the channel, reducing the current from source to drain. Key characteristics include the pinch-off voltage VP, where the drain current reaches its maximum, and the transition between the ohmic and saturation regions as drain-source voltage increases.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

- 2. Home Automation Smart Lighting • The purpose of the home automation system is to control the lights in a typical home remotely using a web application. • The system includes auto and manual modes. In auto mode, the system measures the light in a room and switches on the light when it gets dark. • In manual mode, the system provides the option of manually and remotely switching on/off the light
- 5. Home Automation • The Mode service is a RESTful web service that sets mode to auto or manual (PUT request), or retrieves the current mode (GET request). The mode is updated to/retrieved from the database. • The State service is a RESTful web service that sets the light appliance state to on/off (PUT request), or retrieves the current light state (GET request). • The state is updated to/retrieved from the status database.
- 7. Home Automation • The devices and components used in this example are Raspberry Pi, mini computer, LDR sensor and relay switch. • When in auto mode, the controller service monitors the light level and switches the light on/off and updates the status in the status database. • When in manual mode, the controller service, retrieves the current state from the database and switches the light on/off.
- 9. Smart Parking • The purpose of a smart parking system is to detect the number of empty parking slots and send the information over the Internet to smart parking application back ends. • These applications can be accessed by drivers from smart phones, tablets or from in-car navigation systems. • In smart parking, sensors are used for each parking slot, to detect whether the slot is empty or occupied. This information is aggregated by a local controller and then sent over the Internet to a server.
- 10. Smart Parking
- 11. Smart Parking • The information model defines the attribute (state) of the parking slot virtual entity with two possible values (empty or Occupied). • The next step is to define the service specifications for the system. The services are derived from the process specification and the information model. • The smart parking system has two services (1) a service that monitors the parking slots (using ultrasonic sensors) and updates the status in a database on the cloud (REST web service), (2) a service that retrieves the current state of the parking slots
