The document discusses gear shifting strategies in vehicles. It provides an overview of manual and automatic transmissions. For manual transmissions, the driver operates the clutch and shifts gears. Automatic transmissions electronically change gears based on speed without driver input. The document also reviews recent research on improving manual shift quality and developing automated manual transmissions. It describes how automated systems reduce effort and ensure smooth gear changes but are more complex than manual. Electromagnetic systems are presented as an alternative for situations requiring frequent shifting.
Electromagnetic Braking System using Ultrasonic SensorAI Publications
The concept of our paper is based on the automatic braking system. As we know that most time the accident takes place due to loss of control, drunk & drive and much more breaking reason.In our system there is a sensor that detects the speed of movement of the vehicle and an ultrasonic sensor, that sense the distance of the object in front of the vehicle. The sensor system will sense the speed of the vehicle or object in the front while the microcontroller calculates the distance required to stop the moving vehicle. The whole system is automatic and the braking application will take place without any manual input therefore it will decrease the rate of error hence the rate of road accidents.
Gear shifting mechanism was designed & applied to make the shifting process faster and less destructible for
the driver. The new device must be reliable with small dimensions and maintenance cost. Main aim of this project is to
improve gear shifting process quickly by using devices such as a manual four speed gear box, single pneumatic double
acting cylinders, single pneumatic two position five ways directional control valves, an electrical motor, a belt, two
pulleys, push button, compressor. According to gear shifting method, the driver can do select transmission gear ratio
without moving his/her hands from the steering wheel by putting the gear shifting push buttons on the steering wheel

Transmission is a part of the car which connects the engine to the wheels. When car speeds up, the engine can not speed up in the same proportion, so there are gears involved which match the engine speed to the wheel speed so that we can drive faster or slower than the engine speed.

Abstract
In Olden Days Steering Mechanisms Developed To Turn A Vehicle At A Certain Radius While Negotiating A Turn Had A Greater
Steering Gear Ratio. For A Small Rotation Of The Steering Gear The Steering Wheel Had To Be Given A Greater Effort For
Larger Degree Of Rotation Than That Of The Steering Gear Inorder To Develop Torque For Turning The Vehicle. To Reduce The
Effort At The Steering Wheel, Power Steering Was Developed In The 18th Century. It Not Only Made Steering Easier But Also
Increased The Accuracy In Steering A Four Wheeled Vehicle. Precision Turning In Four Wheeled Vehicles Not Only Prevents The
Vehicle From Skidding But Also Prevents Road Accidents. Various Other Mechanisms Were Also Established For Reducing The
Steering Effort And Precision Turning Including Hydraulics As Well As Electronic Type. Taking Into Account The Various
Systems Of Steering As Well As Using A Bit Of Electronics And Microcontroller Application A Modern Technique Can Be
Developed Using A Servomotor, An Accelerometer And A Microprocessor For An Increased Precision In Steering Of A Vehicle
Which May Be Termed As The “Accelerometer Driven Servomotor Based Steering Gear” Or “A.S. Steering Gear”. In This

The introduction of the automatic transmission did this by offering a “no-muss, no-fuss” form of shifting.
The earliest automobiles offered only manual transmissions, which were similar in principle to today’s stick-shift vehicles.
These cars sported two forward gears and one reverse, coupled to the engine via a series of pedals.
But as cars grew larger and traffic got worse, engineers began searching for a way to have the car “automatically” shift from one gear to another.
Designers spent decades perfecting the modern automatic transmission.
Here we offer a brief introduction and overview of the history of the automatic transmission.
People using old second hand cars in cities, particularly novice drivers engage irrelevant gears; this in turn leads to fuel wastage and importing more petrol and diesel. One simple solution is to educate and alert the drivers. In the current paper we explain how to design a low cost, add-on type of s assembly unit which can be fitted on any existing vehicle.

Analysis, Design and Application of Continuously Variable Transmission (CVT)IJERA Editor
Continuously Variable Transmission (CVT) offers a continuum of gear ratios between desired limits. This allows the engine to operate more time in the optimum range. In contrast, traditional automatic and manual transmissions have several fixed transmission ratios forcing the engine to operate outside the optimum range. The need for a transmission system and the working principle of CVT has been discussed in depth. An attempt has been made to understand the contribution of Hydraulic Actuators, which is an integral part of a CVT. Furthermore, the question of how and why a Torque Converter has effectively replaced a conventional clutch has been answered. The materials used, constructional aspects and stress analysis of the belt has been discussed in detail. A graphical comparison of fuel efficiency between a manual transmission and a CVT in different high end vehicles is included. Recent developments in clamping force control for the push belt Continuously Variable Transmission (CVT) have resulted in increased efficiency in combination with improved robustness. Current control strategies attempt to prevent macro slip between elements and pulleys at all times for maximum robustness.
The Brake-by-wire system has been seen in the various conventional vehicles and in modern cars. If you want to learn more about automotive technology and repair, electric technician school is a destination you must consider.
Dual clutch transmission System is the design to replace commonly used conventional single unit transmission systems.
By using DCT we can reduce fuel consumption up to 15% and it provides best comfort.
Drivetrain was designed and manufacture in such a way that it provides good acceleration, top speed and is reliable on different terrains. To obtain an infinite range of gear ratios so as to obtain the highest torque and as well reach the maximum speed, a CVT along with a self-designed auxiliary reduction gearbox was incorporated. Also driver comfort and fuel economy were include by using CVT.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
