The hydraulic power-split architecture, or the hydromechanical transmission, can exist in over 1000 configurations. Since a specific transmission configuration has unique kinematic characteristic, optimal for one application is different from configurations other applications. This study finds hybrid city bus. uses at least planetary gear set, process of finding suitable bus very time consuming, but this simplifies procedure by utilizing critical speed ratio ω crit , where missing link...
Obstacle avoidance is a desirable capability for Unmanned Aerial Systems (UASs)/drones which prevents crashes and reduces pilot fatigue, particularly when operating in the Beyond Visual Line of Sight (BVLOS). In this paper, we present QuickNav, solution obstacle detection designed to function as pre-planned onboard navigation system UAS flying known obstacle-cluttered environment. Our method uses geometrical approach predefined safe perimeter (square area) based on Euclidean Geometry...
This paper presents the fuel consumption engine map for a 1.3L Perodua Myvi passenger car. The dynamometer and throttle are controlled, to create operating conditions map. Interpolation work is done in MATLAB, 3D used fuel-economy estimation simulation, using city highway drive cycles based on Malaysian roads. economy values generated from simulations similar experimental results.
Workers and employers in carrying out employment relations must comply with labor norms which consist of work occupational safety health norms. Implementation the workplace requires role inspectors supervision. The formulation problem this research is what Labor Inspection mechanism for Norms Workplace? This a type normative legal statutory approach, data collection through library research, analysis carried descriptively. inspections regarding implementation are by under authority granted...
Background: Mining activities in Amonggedo sub-district have an impact on public health and environmental conditions, including data the 10 highest diseases Health Center work area after presence of mining showing 2 types due to metal distribution that continued increase last 3 years, namely Skin Disease Underground Tissue. Methods: The study was conducted with Mix Method, descriptive analysis water quality checks carried out at Laboratory Southeast Sulawesi province Cross Sectional research...
Hydraulic hybrid technology offers superior power density, when compared to competing vehicle technologies. This allows the hydraulic (HHV) absorb most of kinetic energy during braking. paper estimates fuel economy a parallel HHV, based on Perodua Myvi passenger vehicle, controlled by rule-based control strategy. The study simulates HHV city and highway drive cycles that are Malaysian roads. simulation results show 39% improvement operates cycle 31% cycle.
Parameter optimizations of HHV torque distribution must deal with conflicting objectives between the engine and fuel economy without compromising vehicle driving quality. The generation from an internal combustion (ICE) is directly influenced by amount burnt, hence cannot be solved using a classical single-objective optimization method. In this paper, multi-objective genetic algorithm (MOGA) used to optimize power split parallel hybrid hydraulic (HHV) that utilizes ICE motor. simulation runs...
In the present work, effects of two synthetic jet orientations on Nusselt number during combined convection heat transfer are investigated. The experimental study was conducted using orientations−horizontal and vertical, eight different Reynolds numbers, ranging from 0 to 1440. temperatures were measured by five thermocouples positioned at locations, including sink surfaces a heater. A pneumatic cylinder employed supply low-velocity surface. According results, local coefficient decreases...
The groundwater depends on when it is available, more in the rainy and less dry seasons. Fluctuation water availability a significant problem activities continuously requiring large amounts of water, such as agriculture. Hence, necessary to increase number resources meet community's needs. Therefore, layer zone was estimated an initial study at farmland Rejomulyo village, Jati Agung district, South Lampung, using combined method between 1D resistivity Schlumberger array 2D form Wenner...

The data analysis method used qualitative literature survey method. Literature review collection consists articles or journals that have been made before. results the show Search strong on increasing sales. simultaneous large positive effect...
Hydraulic Hybrid Vehicle (HHV) has a great potential to be an efficient drive train for passenger vehicle, yet most of the HHV studies are focused on heavy-duty vehicles. In order apply in vehicles, performance regenerative braking system through-the-road (TTR) parallel architecture needs tested. The is captured by overall efficiency hydraulic pump and mechanical motor. This paper obtains efficiencies motor building test rig measure their torque using load cells. highest 82% 74 %. Both...
Power-split architecture is, in theory, an excellent drive train city bus applications because it combines the advantages of series (control flexibility) and parallel (high-efficiency power transfer) architectures. However, split also increases complexity with more component choices control degrees freedom that, if not properly optimized, would result significant loss. The hydraulic hybrid has disadvantages low speed limit pump/motor unit energy density accumulator. An extensive optimization...
The through-the-road (TTR) hydraulic hybrid parallel architecture uses regenerative braking system that is placed at the rear wheels.This offers a practical solution for an efficient passenger vehicle because it does not interfere with conventional drive train.Thus, unlike other vehicles, this allows use of technology on existing front-wheel-drive vehicle.This paper discusses development involves circuit design and optimization components size.The study simulates 972 models all four segments...
Healthcare workers (HCWs) are known to be at a high risk of being exposed the SARS-CoV-2, or COVID-19 virus because they required interact with their patients distance less than two meters, for more ten minutes time. Due limited resources, most HCWs inadequately protected. This study describes development and performance an affordable full-body isolation pod (isopod). The isopod structure consists composite side panels aluminum poles strips. A clear tarpaulin sheet is used seal its...
