The steel manufacturing process is characterized by the requirement of expeditious development high quality products at low cost through effective use available resources. Identifying solutions that meet conflicting commercially imperative goals such chains hard using traditional search techniques. complexity in a problem increases due to presence large number design variables, constraints and bounds, complex sequential relationships different stages manufacturing. A classic example rolling...
Background Initial foot position (IFP) is one of the important movement strategies that influence neuromuscular and biomechanical control during sit-to-stand (STS) movements. Similarly, stand-to-sit (StandTS) vital in rehabilitation settings for evaluating strength balance descending Understanding how IFP impacts changes factors StandTS can provide valuable insights designing effective programs. Methods Twelve healthy young adults participated this study, examining three symmetric IFPs: (1)...
Total hip arthroplasty (THA) is a widely performed procedure to restore function in patients with degenerative joint diseases. Traditional “press-fit” fixation methods rely on sufficient bone quality for stability, but additional screw often necessary suboptimal conditions. However, comprehensive studies utilizing predictive modeling optimize placement strategies THA remain limited. This study integrates finite element analysis (FEA) deep learning (DL) strategies, enhancing implant stability...
Background Stand-to-sit (StandTS) is an important daily activity widely used in rehabilitation settings to improve strength, postural stability, and mobility. Modifications movement smoothness speed significantly influence the kinematics, kinetics, muscle activation patterns of movement. Understanding impact StandTS on control can provide valuable insights for designing effective personalized training programs. Research question How do affect joint patterns, stability during StandTS? Methods...
Abstract In decision-based design, the principal role of a designer is to make decisions. Decision support crucial augment this role. paper, we present an ontology that provides decision from both “construct” and “information” perspectives address gap existing research focus on these two separately cannot provide effective support. The construct in compromise problem (cDSP) used multiobjective design information for making archived as cDSP templates represented using frame-based facilitating...

The purpose of this study was to examine the effect a 12-week Wheelchair Tai Chi Ball (WTCB) intervention, combination mind-body exercise with strength training, on physical and mental health functional abilities among elderly disability. Twenty-six persons participated in study, nine WTCB group participants ten control completed study. practised WTCB12 twice/week for one hour each time. did their daily routine without intervention. outcomes measures were: Pain Self-Efficacy Questionnaire...
In this paper, we explore the design space associated with realization of automobile steel gear blanks manufactured using hot forging. ABAQUS, a commercially available software package, is used to simulate forging process. Surrogate models are developed and model solution space. Then compromise Decision Support Problem (cDSP) feasible Results presented as ternary plots that allow designer visualize trade-offs between competing goals such reducing size underfill, flash (excess material),...
Crouch gait is a motor complication commonly associated with cerebral palsy, spastic diplegia, stroke, and motor-neurological pathologies, broadly defined as knee flexion in excess of 20° the cycle. Uncorrected crouch results fatigue, joint degradation, loss ambulation. Torsion springs have been used cycling to store energy reduce fatigue quadriceps during extension. SolidWorks was design passive exoskeleton for knee, incorporating torsion stiffnesses 20,000 N/mm 30,000 at correct...
Partial paralysis caused by spinal cord injury (SCI) or stroke are two of the most prevalent forms physical disability. Through proper gait training, people with incomplete SCI have more potential to retain regain ability walk than those complete SCI. To help patients who these disabilities function walking unassisted, robotic training device (RWTD) has been developed perform rehabilitation. This research plays a pivotal role in advancing medical technology and rehabilitation conducting...
The role of microstructure is quite significant in fretting because the scale plastic strain localization near surface on order key features. A dual-phase Ti-6Al-4V alloy that tends to be susceptible considered as a model material. Fretting simulated using two-dimensional finite element analysis. crystal plasticity theory with planar triple slip idealization employed represent hexagonal close packed structure α phase Ti. Modifications system strengths enable multiple phases considered. In...
A transmission gear is generally produced by a sequence of several processes from steelmaking to final machining and surface treatment. The intermediate such as hot rolling induce microstructure evolution phase transformation which play significant role in determining the mechanical properties fatigue strength gears. Therefore, these should be carefully considered performance end product. In this paper, an integrated multiscale robust design approach using Inductive Design Exploration Method...

Critical such as strain rate, temperature, heat transfer coefficient and strip width are only considered study. Ternary plots constructed utilized obtained thereby identifying...
Patients who are suffering from neuromuscular disorders or injuries that impair motor control need to undergo rehabilitation regain mobility. Gait training is commonly prescribed patients muscle memory. Automated-walking devices were created aid this process; while these establish accurate ankle-path trajectories, the knee and hip movements inaccurate. In work, a redesign of leg assembly in multi-purpose robotic device (RoboREHAB) was explored improve hip- knee-movement accuracy by adding an...
Abstract As a patient gets older, the chances of sustaining motor disability increase. Such disabilities impair patient’s ability to perform daily activities and undergo rehabilitation regain mobility. Exoskeleton devices aqua therapy have been used make this process easier. However, most exoskeletons do not replicate natural gait pattern accurately there does exist lower-limb device that provides training with zero-gravity assistance. The objective for study is design two control systems...
