The current paper presents an integrated control strategy to improve rollover stability of a vehicle by considering chassis key subsystems. In order to achieve this goal, a quantitative study on control authority and the effective working region of active front steering (AFS), active braking (AB), and active suspension (AS) control for rollover prevention is carried out based on a full vehicle model which includes the non-linear tyre model and the effect of dynamic coupling. After investigating the control authority and effective working area of AFS, AB, and AS subsystems, an integrated control strategy for rollover stability is formulated. In this formulating process, the control strategy for each subsystem is also designed by considering its contribution to rollover stability. A comparison between the proposed integrated control strategy and the single control action of each subsystem is made through computer simulation. It is demonstrated that both anti-rollover ability and lateral stability are greatly improved by implementing the proposed integrated control scheme. Specifically, the peak of roll angle and the root mean square (RMS) of side slip angle with integrated control are reduced by 38.9 per cent and 47.1 per cent, respectively, relative to those of the passive system.

This paper presents results of an initial investigation into models and control strategies suitable to predict and prevent vehicle rollover due to untripped driving maneuvers. Outside of industry, the study of vehicle rollover inclusive of experimental validation, model-based predictive algorithms, and practical controller design is limited. The researcher interested in initiating study on rollover dynamics and control is left with the challenging task of identifying suitable vehicle models from the literature, comparing these models in their ability to match experimental results, and determining suitable parameters for the models and controller gains. For vehicles that are deemed to be susceptible to wheel-lift, various open-loop control strategies are implemented in simulation. The primary assumption in their implementation is that the vehicle in question is equipped with a steer-by-wire system. Nomenclature

Monitoring of warehouse inventory data processing is an important thing for companies. PT Talaga mulya indah is still manual using paper media, causing problems that have an effect on existing information, namely: problems with data processing of incoming and outgoing goods. And the difference between data on the amount of stock of goods available with physical data, often occurs inputting data more than once for the same item, searching for available data, and making reports so that it impedes companies in monitoring inventory of existing stock of goods. Which aims to create a system that can provide updated information to facilitate the warehouse admin in making inventory reports, and reduce errors in input by means of integrated control. In this study, the authors used the data collection method used in this analysis using the method of observation, interviews, and literature review (literature study). For analysis using the PIECES analysis method. Furthermore, the system design used is UML (Unified Modeling Language). The results of this study are expected to produce the right data in the process of monitoring inventory data processing, also can provide the right information and make it easier to control the overall availability of goods.

Rinamba opacicollis Cameron (Hymenoptera: Braconidae) was collected from Chikkamagaluru, Karnataka, India for the first time from the larvae of white stem borer, Xylotrechus quadripes Chevrolat infesting arabica coffee. Its role in the biological or integrated control of X. quadripes remains to be evaluated. White stem borer could be the first host record of this parasitoid all over the world.
