When designing control laws for systems with constraints on the tracking performance, control allocation methods can be utilized. Control allocation methods are used when there are more command inputs than controlled variables. Control allocators can be used to address surface saturation limits, structural load limits, drag reduction constraints, or actuator failures. Most transport aircraft ha...

This paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. Since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

Kumari S. (2009): Detection of Cherry leaf roll virus and Strawberry latent ring spot virus by one-step RTPCR. Plant Protect. Sci., 45: 140–143. A one-step reverse transcription-polymerase chain reaction (RT-PCR) protocol was developed and used for the detection of Cherry leaf roll virus (CLRV) and Strawberry latent ring spot virus (SLRSV). The protocol was used to test infected screen house pl...

In this issue of Blood, Brunstein and colleagues report the results of the first study to test the safety of human umbilical cord blood– derived regulatory T cells (Tregs), an approach designed to decrease graft-versus-host disease.1 Transplanters, like Sisyphus of myth, have struggled mightily with trials of pharmacologic immunosuppressive drugs—we roll the rock up the mountain, only to see it...

The first part of the paper describes the targets related to the design of an Active Roll Control (ARC) system, based on the hydraulic actuation of the anti-roll bars of an automobile. Then the basic static and dynamic design principles of the system are commented in detail. The second part of the paper presents the Hardware-In-the-Loop (HIL) test bench implemented to evaluate the designed syst...

hot rolling of a large ring of titanium alloy (lrt) is a highly nonlinear incremental forming process with coupled mechanical and thermal behaviors (mtbs) which significantly affect microstructure and properties of the ring. the feed rate of idle roll and the rotational speed of driver roll have major effects on ovality of the ring. in this paper, the effects of these parameters on the ovality ...

In this work, the strength of cold roll bond of the commercially pure titanium (CP Ti) sheet and the effect of TiO2 nanoparticles on bond strength was investigated. Through the accumulative roll bonding process, which is considered among the important severe plastic deformation processes, the creation of suitable bonds plays a significance role in the ultimate strength of the bond. Thus, resear...

In the present study, the presence of brass mesh on the bond strength of aluminum (AA1050) strips in the cold roll bonding process was investigated. The influence of various process parameters including reduction in thickness, pre-rolling annealing, initial thickness of the strips, and post-rolling annealing was also considered. After cold roll bonding process, peeling test was carried out and ...
