By identifying the specific disasters and crises pastoralists successfully avert on the ground and in real time, we move beyond a reductive or otherwise partial view of their real-time activities. While the chronic challenges of inequality, marketisation, precarity, marginalisation, and the climate emergency are well-documented, they represent an incomplete and, as such, misleading picture. I argue that the implications of these avoided disasters are critical to local development yet remain largely overlooked in current pastoralist policy, management, and their critiques.

The importance of the wake/boundary layer interaction to the design and optimization of high-lift multi-element airfoils has led many researchers to make detailed experimental and theoretical investigations of such flows. The present work was undertaken to develop a simple mathematical model for computation of merging turbulent wakes and boundary layers in two-dimensional flows at zero pressure gradient. An integral calculation method has been developed, and used to predict with reasonable success the mixing of an aerofoil wake with a flat plate boundary layer.

<div class="htmlview paragraph">The B-2 Advanced Technology Bomber has a very unconventional shape and unique requirements to fulfill its mission. In order to satisfy the demanding requirements for the B-2's excellent handling qualities a flight control system was developed with unrivaled performance and sophistication. A key subsystem of the flight control system is the Flight Control Actuation System (FCAS). The FCAS is a self-contained quadraplex system that includes hydraulic actuators with direct drive servovalves for all surfaces, electronic actuator loop closures, and redundancy management.</div>

The decentralized control of discrete time stochastic linear systems is considered in this paper. The decentralized control laws are obtained by determining a sequential Nash equilibrium point for a set of quadratic cost functions. In the absence of disturbances, the Nash equilibrium set has the property of driving the state of the closed-loop system to the origin in finite time or asymptotically. In addition, the control law is a linear function of the instantaneous output measurements and can be computed on-line using relatively simple algorithms.

A computer graphics system expedites the acquisition of reliable data for use in analysis and quality inspection of parts and tools.

The integration of successive frames from a 128 x 128 infrared detector array is complicated by (1) the large number (i.e. 16,384) of detector elements in the array, (2) the necessity of achieving computational precisions better than 0.01%, and (3) the space and power limitations that are implied by a 77°K focal plane location for the processing circuitry. The design of an analog frame integrator to meet the above requirements is discussed. In addition, a correlated triple sampling circuit, which is incorporated in the frame integrator and which can be adapted to a variety of read-out techniques, is described.
