Some tracking problems for aerospace models with input constraints
… of trackable reference trajectories, and the input-to-state stability of the controller performance under actuator errors of arbitrarily large amplitude. The significance of our UAV results is the generality of the trackable trajectories, the input-to-state stability properties of the tracking …

Distributed model predictive control based consensus of general linear multi-agent systems with input constraints
… additive disturbance; (2) linear MASs with input constraints underlying distributed communication networks. In Chapter 2, a tube-based robust MPC consensus protocol for constrained linear MASs is proposed. For undisturbed linear MASs without constraints, the results on designing a …

Pinpointing production constraints faced by female-headed households in rural Malawi
… whether female-headed households face unique constraints to maize production in Malawi is presented. A simulation is performed on the first-order equations of smallholder maize production functions and predicted marginal products are tested against observed input-output price ratios to detect …

Identification and control of nonlinear processes with static nonlinearities.
… structure, where the nonlinearity is on the input, is used. Cardinal spline functions are used to identify the multivariable input nonlinearity. Highlycoupled nonlinearity can also be identified due to flexibility and versatility of cardinal spline functions. An approach that can be used to …

An efficient sequential BTRS implementation
… based on guarded atomic actions (GAA). The input language to the compiler which forms the basis of this work is a hierarchical tree of modules containing state, interface methods, and rules which fire atomically to cause state transitions. Since a schedule need not be specified, the program …

Synthesizing motion sequences from sample motions to satisfy environmental constraints
… human motion sequences satisfying environmental constraints can be created by motion capture, which is a reliable way to reproduce human motions. However, motion capture data is difficult to modify in order to obtain variant motion sequences for multiple tasks. In this thesis, a system for …

Comparison of Strategies for the Constraint Determination of Simulink Models
… it is of utmost importance to determine their input and output constraints. Determining input constraints is a trivial matter, but the constraint determination of a system's output values is a serious and challenging problem that historically has entailed an exhaustive exploration of the …

Generating structurally complex tests from declarative constraints
… test generation for programs that take as inputs structurally complex data, presents an automated SAT-based framework for testing such programs, and provides evidence on the feasibility of using this approach to generate high quality test suites and find bugs in non-trivial programs. The …

Gender and performance of micro and small enterprises in the uMkhanyakude District
… of women staying in business. Financial and input constraints are major restrictions on women staying in business. Finally, married women are found to be less likely to stay in business than single women. The study concluded that Grameen-bank type programmes which offer poor rural women …

Robust Control of Input-Delay Linear Parameter-Varying (LPV) Systems
… majority of engineering systems are affected by input delays. Since there is a lag between the control signal and the system's response to it, input delay degrades a system's performance by reducing the bandwidth and even cause instability in severe cases. This research on input-delay LPV systems …
