There may be occasions when the diner is unable to manage the tasks of eating and drinking without help from a family member or carer. Help should be thoughtfully provided, and the diner should, whenever possible, be in control of the proceedings, eating at his/her own pace and selecting what next to eat. If you are helping someone to eat a meal or to take a drink, position yourself in front or slightly to one side of the diner, so that you can see each other and communicate more easily. Make sure the diner is adequately supported in...

The problem of investigation of time delay systems has been explored over many years. Time delay is very oft en encountered in various technical systems, such as electric, pneumatic and hydraulic networks, chemical processes, long transmission lines, etc. The existence of pure time lag, regardless if it is present in the control or/and the state, may cause undesirable system transient response, or even instability. Consequently, the problem of stability analysis for this class of systems has been one of the main interests for many researchers....

A further considerable simplification in the mechanics resulted from introducing microcomputers in connection with decentralized electrical drives, as can be seen from electronic typewriters, sewing machines, multi-axis handling systems, and automatic gears. The design of lightweight constructions leads to elastic systems which are weakly damped through the material. An electronic damping through position, speed, or vibration sensors and electronic feedback can be realized with the additional advantage of an adjustable damping through the algorithms.

SAE STANDARDS Fifteen of these standards for the year 2003 that pertain to brake or clutch components are briefly described in the remainder of this chapter. Other standards apply to brake line hoses, fluids for hydraulically activated brakes, brake cables, clutch flywheels, and so on. Descriptions of these standards are arranged in the numerical order of the standards. This order differs from the coded order found in the SAE Handbook, wherein the first digits are listed in numerical order, followed by the second digits, and so on.
