  • These are special words and phrases directly indicating the structure of the argument to the hearer. Two main conclusions are drawn: I) clue words can occur in conjunction with coherent transmissions, to reduce processing of the hearer 2) clue words must occur with more complex forms of transmission, to facilitate recognition of the argument structure. Interpretation rules to process clues are proposed. In addition, a relationship between use of clues and complexity of processing is suggested for the case of exceptional transmission strategies. ...

  • The current control problems present natural trend of increasing its complexity due to performance criteria that is becoming more sophisticated. The necessity of practicers and engineers in dealing with complex dynamic systems has motivated the design of controllers, whose structures are based on multiobjective constraints, knowledge from expert, uncertainties, nonlinearities, parameters that vary with time, time delay conditions, multivariable systems, and others.

  • As SUNY New Paltz administrators strive to achieve the college’s mission and goals and to provide accountability for their operations, they need to continually assess and evaluate their internal control structure to assure that it is well designed and operating effectively, appropriately updated to meet changing conditions, and provides reasonable assurance that the objectives of the department are being achieved.

  • Historically, a course on data structures has been a mainstay of most computer science departments. Over the last 18 years, however, the focus of this course has broadened considerably. The topic of data structures has now been subsumed under the broader topic of abstract data types (ADTs)—the study of classes of objects whose logical behavior is defined by a set of values and a set of operations.

  • PID controllers are probably the most commonly used controller structures in industry. They do, however, present some challenges to control and instrumentation engineers in the aspect of tuning of the gains required for stability and good transient performance. There are several prescriptive rules used in PID tuning. An example is that proposed by Ziegler and Nichols in the 1940's and described in this note.

  • Traditional analyses of the control and regulation of steady-state concentrations and fluxes assume the activities of the enzymes to be constant. In living cells, a hierar-chical control structure connects metabolic pathways to signal-transduction and gene-expression. Consequently, enzyme activities are not generally constant. This would seem to compromise analyses of control and regulation at the metabolic level.

  • Intuitively, a Ruantifier is any word or phrase that expresses a meaning that answers one of the questions "How many?" or "How much?" Typical English examples include all, no, many, few, some but not many, all but at most a ver~ few, wherever, whoever, whoever there is, and also, it can be argued, 0nly (Keenan, 1971), also (Cushing, 1978b), and the (Chomsky, 1977). In this paper we review an empirically motivated analysis of such meanings (Cushing, 1976; 1982a) and draw out its computational significance.

  • Robotics is the applied science of motion control for multi-axis manipulators and is a large subset of the field of "mechatronics" (Mechanical, Electronic and Software engineering for product or systems development, particularly for motion control applications). Mechatronics is a more general term that includes robotic arms, positioning systems, sensors and machines that are controlled by electronics and/or software, such as automated machinery, mobile robots and even your computer controlled washing machine and DVD movie player....

  • The interest in robotics has been steadily increasing during the last decades. This concern has directly impacted the development of the novel theoretical research areas and products. Some of the fundamental issues that have emerged in serial and especially parallel robotics manipulators are kinematics & dynamics modeling, optimization, control algorithms and design strategies. In this new book, we have highlighted the latest topics about the serial and parallel robotic manipulators in the sections of kinematics & dynamics, control and optimization.

  • Structural Testing is used to verify the static strength, or fatigue strength of a component by applying measured loads to the test item. Testing can be done to failure, to contractual requirements or to validate finite element model predictions. DTB has successfully completed thousands of structural tests on items ranging in size and complexity from simple coupons to entire aircraft. Fatigue Testing is carried out with the objective of determining the relationship between the stress range and the number of times it can be applied before causing failure....
