Hydraulic Jack is a device that uses force to lift heavy loads. The primary
mechanism with which force is applied varies, depending on the specific type of
jack, but is typically a screw thread or a hydraulic cylinder. Jacks can be
categorized based on the type of force they employ: mechanical or hydraulic.
Mechanical jacks, such as car jacks and house jacks, lift heavy equipment and are
rated based on lifting capacity (for example, the number of tons they can lift).
Hydraulic jacks tend to be stronger and can lift heavier loads higher, and include
bottle jacks and floor jacks.

This project and implementation is very useful for long journey vehicle and this setup
helps to raise vehicle by using battery or engine power. An automatic pneumatichydraulic jack comprises a mini air compressor and automatic hydraulic jack to serve
as an on-vehicle tool where as the power of the battery on the vehicle is used to drive
the mini air compressor which compresses air to serve as its primary force. The air
enters an entry channel from an air inlet nozzle and passes to an air chamber via a
changeover valve to push a small air-oil piston, thus converting air pressure into
hydraulic pressure on the other side of the piston which enters into a large hydraulic
cylinder via a check valve and pushes a large piston. The downward movement of the
small air-oil piston causes engagement with and turns the changeover valve, thus
connecting the air chamber channel to an exhaust channel and the entry channel to the
storage tank channel which enables the oil storage tank to supply the small hydraulic
cylinder with oil under pressure and make the small air-oil piston move upwards when
the small hydraulic cylinder is filled with oil, the small air-oil piston turns the
changeover valve to connect the air entry channel to the air chamber channel again,
thereby completing the cycle. Such reciprocation converts the air pressure into
hydraulic pressure to push the big piston which in turn, jacks up the vehicle. To lower
the vehicle, an oil return screw is turned to allow the oil to return to the oil storage tank
via a return channel

Abstract: This project was discussed about the design and implementation of automated multiple water filling machine using Geneva mechanism. Generally, the function of the machine is to fill the water automatically into bottles through a moving bottle plate. This project is the combination of Geneva and electrical syncronous motor system. This project is divided into four sections, the loading section, the bottle plate section and filling section, where the whole sections is controlled by Geneva. The entire system is more flexible and time saving.
Review Paper on New Automotive Camless Engineijtsrd
Internal combustion engine occupies a significant spot in present day. with the most recent plan alteration in different part being advanced to improve the efficiency and generally speaking performance, one segment has been kept untouched that is camshaft. Cam control the breathing channels of the engine that is the planning of valves through which fuel air mixture enters and fumes is driven out. with help of push rods , rocker arms, stiff springs. With increasing performance demands engine specialists and researchers over the world are perusing radical cam less structure which promises to give ICEs a greater improvement in effectiveness. The fantasy about accomplishing cam less technology is shutting reality at rapid rate. With cam less technology put into practice, the engine power can be improved, pollutant emissions could be controlled and better mileage is acquired, in addition to that the whole mechanism of pulley or belt drive is replaced by the camless engine with greater efficiency than earlier i.e intake and exhaust of the IC engine by camless actuation technology with the camless engine variable valve timing also controls the intake and exhaust gas recirculation. Its one of the major advantage is it offers continously variable and independent control of all types of motion.

Design of Industrial Electro-Hydraulic Valves, New ApproachIJERA Editor
A fully flexible valve actuation systems are being under consideration as an enabling technology for advanced internal combustion engine concepts. Electro-hydraulic valve actuator systems are being considered as a dominating variable valve technology. Compared to the servo control system, the system using a proportional valve has the advantages of low price, high anti-pollution ability and high reliability. Unlike existing electromechanical or servo actuated electro-hydraulic valve actuation systems, precise valve motion control is achieved with an internal feedback mechanism. This feedback mechanism can be turned on or off in real-time using simple two state valves which helps reduce the system cost and enables mass production.

Automation of Fixtures Using Hydraulic Power Pack for a Bogie UnderframeIOSR Journals
In this era of automation technologies manufacturing sectors have placed very high demands on fast and reliable production methods. This work is the evaluation & analysis of the existing clamping system. The current system uses manual clamping of fixtures for holding the work piece in the proper position while welding process is being done on the part. The evaluated system uses hydraulic vertical swing clamps for holding the work piece driven by hydraulic power pack. Thus the new system achieves automatic and simultaneous clamping of fixtures.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
