DRIVER CAUTION SYSTEM FOR SAFETY USING SMART LED DISPLAY BOARDS

To prevent accidents and also to alert the motorists concerning the speed limits such type of places the highway department have placed the signboards. Nowadays individuals are driving extremely fast, accidents are occurring frequently, we lost our valuable existence by looking into making small mistake while driving (zone wise, hillsides area, highways). But, May too easy to view that sort of signboards and there's a way for accident. To intimate the motive force concerning the posted speed limit at zones and also to identify crashes instantly, is completed by way of using MEMS, RF, Gps navigation, GSM technology. The primary objective would be to design a good Display controller intended for vehicle’s posted speed limit and crash alerts which could operate on an embedded system. Smart Display & Control (SDC) could be custom-designed to suit right into a vehicle’s dashboard, and displays info on the automobile

AN EMBEDDED DEVICE TO REGULATE AIR CIRCULATION IN HOT CONDITIONS IN A VEHICLE SYSTEM

Microcontroller controls the positioning of the home windows autonomously and individually from the driver’s presence, following predefined formula that utilizes sensors data acquired in the vehicle’s surroundings. The module is implemented utilizing a microcontroller like a central logical unit and a number of sensors which offer sufficient data to make sure functional, but additionally efficient, reliable and safe ventilation and safety of passengers. To be able to mitigate overheated interior of the vehicle parked within the hot summer time sun and therefore to help make the getting into the automobile much more comfortable, and stopping passengers from injuries when accident occurs, microcontroller managed module for automatic ventilation of car interior is created. The ventilation process is conducted by opening vehicle home windows slightly, which helps air to flow. Besides temperature, the most crucial factors to make sure quality implementation of ventilation are detected movements round the vehicle, the existence of humidity along with other. As well as microcontroller controls airbags position. This project uses controlled 5V, 500mA power. 7805 three terminal current regulator can be used for current regulation. Bridge type full wave rectifier can be used to rectify the ac creation of secondary of 230/12V step lower transformer. Using the vibration sensor data for enabling the environment bags open when accident happened towards the vehicle. This paper shows the constituents, their intention and abilities, pros and cons, in addition to potential implementations and upgrades. The exam results give understanding of utilization options of the module and it is effectiveness

Time evolution of the Rabi Hamiltonian from the unexcited vacuum

The Rabi Hamiltonian describes a single mode of electromagnetic radiation interacting with a two-level atom. Using the coupled cluster method, we investigate the time evolution of this system from an initially empty field mode and an unexcited atom. We give results for the atomic inversion and field occupation, and find that the virtual processes cause the field to be squeezed. No anti-bunching occurs.Comment: 25 pages, 8 figures, RevTe

Texture Image Classification and Retrieval Using Multi-resolution Radial Gradient Binary Pattern

In image classification and retrieval applications, images are represented by a set of features. These features are extracted from both spatial and wavelet transformed input images. The wavelet transform decomposes images into multiple resolutions by separating smooth and sharp information in individual channels to give more details about the image. Each level of smooth and sharp decomposed channels is individually involved in texture feature extraction. It is difficult to achieve better results in image classification and retrieval applications with fewer discriminant details of the image. Even though each level of the smooth channel correlates with its successive decomposition levels, these feature extraction methods do not consider the relationship between the multiple levels of decomposed images. This motivates the proposed work to extract the correlation between the different levels of wavelet decomposed images. The proposed work (i) encodes the local difference obtained from multiple radii across the different levels of wavelet decomposed channels, (ii) assesses the proposed texture feature extraction method using classification and retrieval experiments with five different wavelet filters over twelve image databases and (iii) analyses the importance of similarity measures involved in the proposed feature-based image retrieval experiments
