This Digital Parking System ECE Project Download aim is to design a three tier parking system. This project shows how to keep a track of how cars are parked. The lowest tier parks cars for short interval of time. The middle tier contains cars that remain for 1-3 hours. The upper tier parks those cars which remain for three hours.

This is a technology that takes the picture of the approaching car present at the main gate. The system assigns a password to the car user who is visiting for the first time. The user enters the password and the system checks the space for the parking in the parking area. 

If space is available then the electronic main gate open and the user will get access to park the car inside. If no space is available then the main gate will not open. In this case, the system checks the car parked which is present for the longest interval and notifies its user to remove the car park parked in the upper tier.

The software tools used in this project are Turbo c++ and JCreator 2.5, Mozilla Firefox browser, Web server, and MY SQL for database management. The modules of this project are User profile module, Device Management Module, Time management module, Geographical module, Security Module, Design Module, and Cost Management Module.

The Design Requirements with Basic input and output are Number of vehicles entering/exiting the parking lot and Number of violators. The features of this project have successful functioning such as technology, feasibility, efficiency, and optimum cost.

Conclusion:

The project concludes on to develop a technology of advanced parking system that will implement many innovations. This technology allows maximizing of parking capabilities, intimates drivers, and prevents unauthorized vehicles. The unauthorized vehicles get tracked by a camera that records license plates of the corresponding vehicles and the images will be transferred to a recording device.

Digital Visitor Counter Electronics Seminar Abstract Digital visitor counter is a reliable circuit which over takes the role of counting number of persons/visitors in the room very accurately. When anyone enters into the room, the counter is incremented by one and the total number of persons present in the room is displayed on LCD. Visitor counting is a counter of the number of visitors entering and exiting in offices, malls, sports, venues, room etc. Visitor counter helps to maximize the effectiveness and efficiency of employees, floor area and sales potential of an organization.

Visitor counting has not any limit to the entry/exit point of a company but it has a wide range of applications which give information to management on the volume and flow of people in a location. The basic method for counting the number of visitors includes sharing human auditors to standard manually that tallies the visitors who enter or exit by a particular location. It is readily available in the market and is easy to build.

The counter is incremented by one as somebody enters into the room and number of persons is displayed on LCD present in a room. It is done by microcontroller. It gets the signals from the sensors and these signals are stored in ROM.

Microcontroller AT89s52 continuously operates the sensor as a person passes by the sensor and then the falling light rays on the sensor are obstructed and, this obstruction is sensed by the Microcontroller and this controller will increment the counter by 1 in the LCD display.

The components used in this system are 555 Timer IC, LCD [16*2], Microcontroller [AT89s52], Frequency Crystal [11.0592 MHz], Capacitors, Voltage regulator [7805], LDR, and Relay. There are two types of capacitors used. They are Paper Capacitor [22pf] and Electrolytic Capacitor [10 uf -16 V].

Conclusion:

This project provides enriched learning experience to count the number of visitor in any particular location.

Digital Invisible Ink Data Hiding Based on Spread-Spectrum: In olden days with the help of steganographic skills, secrets messages were hidden. Steganographic techniques consist of two branches, linguistic steganography and technical steganography. Linguistic steganography has two classes of methods. Delivering secret messages by an open code and semagrams secrets expressed in the form of drawing or script.

In real world, writing with invisible ink is the most renowned skill as per technical steganography. Invisible ink is a substance which is used in steganographic schemes to write the secret messages invisibly on papers. During writing the secret message, the ink is invisible and later on the hidden message made visible with different methods.

For instance, message written with diluted acid liquids is made visible by heating the paper. So by applying chemical liquids or vapors on the paper, viewing the paper under ultraviolet light etc invisible message can be made visible.

Based on steganography, some characteristics of invisible-ink are as follows: Prenegotiated manipulations for correct extraction of genuine secrets, the received paper deformed by prenegotiated manipulations, and cover messages as camouflage etc. Spread-spectrum watermarking technique is also a well known data hiding schemes.

There is a positive contribution with the pseudo-randomness of the watermark vector to hide the message and the ratio of valid messages bits is reduced to about 50% and the message bits are unpredictable.

 Digital Invisible Ink Data Hiding Based on Spread-Spectrum Conclusion:

Models, implementations, and applications of invisible ink for data hiding are illustrated in this document. Secret messages can be embedded without alternation to the original work. The proposed digital-invisible-ink scheme gives secrecy by enabling plausible deniability. Potential dangers for delivering secrets with the help of watermarking applications are also used to hide the data. With the help of digital-invisible-ink schemes, we are still trying to have better robustness against geometric and filtering attacks in the active-warden scenario that should also provide better secrecy.

Detection and Removal of Cracks and In Digitized Paintings Project Abstract: There are many things which get breaks in the substrate like old paintings, the varnish or the paint. These breaks are called cracks or craquelure and caused due to drying, aging, and mechanical factors. Age cracks result because of nonuniform contraction in the canvas whereas drying cracks are due to the evaporation of components of volatile paint and shrinkage of the paint and mechanical cracks are caused with painting deformations like vibrations and impacts.

Hence digital image processing techniques are used to detect and remove the cracks on digitized paintings. It is also used as a nondestructive tool for the actual restoration. The user must select an area on each crack that to be restored. The formers generally based on partial differential equations (PDEs) and on the calculus of variations.

The technique includes the following stages. They are crack detection, separation of the thin dark brush strokes which are misidentified as cracks, and crack filling (interpolation).

The cracks are identified and detected by thresholding which is an integrated methodology for removal of cracks. Furthermore, a thin dark brush strokes are removed with the help of either a median radial basis function neural network or a semi-automatic procedure based on region growing. Ultimately, crack filling such as median filter is done.

The existing tools like PhotoShop has an option like blur. This option roughly pixel the transformations but there is no exact filling procedure in this existing system. The proposed system has exact crack detection and filling procedure which includes top-hat transformation, region-growing algorithm (grassfire algorithm) and median filter procedures.

Conclusion:

This paper is all about the cracks which are detected with the help of top-hat transform. The thin dark brush strokes are misidentified as cracks which are separated either by an automatic technique (MRBF networks) or by a semi-automatic approach.

Design And Implementation Of 64 Bit ALU Using VHDL: VHDL is standard language of an industry for the modeling, description, and synthesis of digital circuits and systems. It extends as Very High Speed Integrated Circuits (VHISC) program. It needs standard language for describing the structure and function of integrated circuits (IC).

VHDL is suited with programmable logic devices for designing. Now engineers can quickly and efficiently accomplish a design with the help of large capacity CPLDs and FPGAs of 500 to 100,000 gates. This language is a high level language to describe large circuits to market rapidly.

VHDL gives support to creation of libraries to store components for reuse in particular designs. It provides probability of code between synthesis and simulation tools. It is a device of independent design. It also converts a design from a programmable logic to an ASIC implementation.

VHDL enables logarithmic register transfer and logic gate level. With the help of VHDL, a user is able to abstract implementation details of a design. VHDL provides mixed level design described in a high level of abstraction and also in a lower level of abstraction. The mixed level simulation focuses on the design of the timing critical modules.

VHDL describes a model for a digital hardware device. It specifies the external and internal views of the device. The building blocks of VHDL language are Entity, Architecture, Package, and Process. There are different modelling styles such as dataflow style of modelling, structural style of modelling, and behavioral style of modeling etc.

Design And Implementation Of 64 Bit ALU Using VHDL Conclusion:

Behavioural modelling and structural modelling provide the implementation of 64 bit ALU. The design of an ALU includes logical operations which are implemented with simple gates to operate independently. The mathematical operations of ALU are performed using repeated additions. Multiplication and division are designed as a single unit along with other operations of ALU. The design has three modules and outputs are combined at the top most level using a multiplexer.

Design Verification and Synthesis of Floating Point Arithmetic Unit: An arithmetic-logic unit (ALU) carries out arithmetic and logic operations on the operands instructed by the computer. ALU is the part of computer and is divided into two units as an arithmetic unit (AU) and a logic unit (LU). Few processors have one or more number of AU like one is for fixed-point operations and another for floating-point operations.

Arithmetic operations such as addition, subtraction, multiplication and division are performed by arithmetic and logic unit (ALU) performs. It also performs logical operations such as AND, OR, shift left and shift right etc.

A floating-point unit (FPU) is also a part of a computer system which carries out operations on floating point numbers. The typical operations are addition, subtraction, multiplication, and division.

Integer arithmetic performs operations on integers. It takes integers as an input and also gives integer as an output and the operations of integer arithmetic such as addition, subtraction, multiplication, division, logical operations and shifting.

Adders are implemented by taking multiple copies of simple components and the components are half adders and full adders. Division is implemented in the form of formula as Dividend=(divisor * quotient) + remainder. A simple floating point number (N) uses a fraction (F), base (B), and exponent (E) which is expressed as N=F * BE. Logic synthesis is the method of converting a high-level description into an optimized gate-level presentation and given by standard cell library and certain design constraints.

Conclusion:

The floating point arithmetic unit contains floating point adder, floating point subtractor, floating point multiplier, floating point divider thoroughly verified by the test bench module. Using RTL Cadence Synthesis Tools, more information is provided about cells, power, timing analysis for performing floating point operations. With the help of design of arithmetic unit, we can implement low power consuming floating point and high speed processors and also parameterized modules can be implemented for floating point arithmetic unit.
