Abstract:

One of the key problems in the development of nanosatellites is to provide a given temperature range for the operation of the on-board computer. The constantly increasing information load leads to the need to use more advanced processors with high thermal design power (TDP). The indicated thermal regime of processors can be achieved using remote heat removal systems - miniature loop heat pipes. Using a model of nanosatellite as an example, a thermal control system with miniature loop heat pipes is designed. The simulation was carried out in the Siemens NX program in the elliptical and geostati

Abstract:

One of the key problems in the development of nanosatellites is to provide a given temperature range for the operation of electronic equipment, the heat transfer of which can be tens of watts. Thermoregulation systems traditional for large spacecraft are not suitable for nanosatellites due to limitations on their mass and size characteristics. The indicated thermal regime of nanosatellites can be achieved using remote heat removal systems - miniature loop heat pipes. In recent years, their mass production has been established in Russia, but they have not yet found wide application in nanosatel

Abstract A method of heuristically solving large and extremely large traveling salesman problems is suggested. The solver is a specific genetic algorithm producing approximately shortest routes the fastest of known heuristics without losing much in accuracy. The method consists in parallelizing the problem by clustering its nodes and finding the best route passing through the centroids of the clusters. The open-loop subroutes of the clusters are connected via specific nodes. These specific nodes referred to as connectors are determined as those for which the distance to the depot is maximal an

Abstract:

Tightly Coupled Processor Arrays (TCPAs), a class of massively parallel loop accelerators, allow applications to offload computationally expensive loops for improved performance and energy efficiency. To achieve these two goals, executing a loop on a TCPA requires an efficient generation of specific programs as well as other configuration data for each distinct combination of loop bounds and number of available processing elements (PEs). Since both these parameters are generally unknown at compile time—the number of available PEs due to dynamic resource management, and the loop bounds, because

Abstract:

Over the last decade processor speed has increased dramatically, whereas the speed of the memory subsystem improved at a modest rate. Due to the increase in the cache miss latency (in terms of the processor cycle), processors stall on cache misses for a significant portion of its execution time. Multithreaded processors has been proposed in the literature to reduce the processor stall time due to cache misses. Although multithreading improves processor utilization, it may also increase cache miss rates, because in a multithreaded processor multiple threads share the same cache, which effective

The quantum approximate optimisation algorithm is a p layer, time variable split operator method executed on a quantum processor and driven to convergence by classical outer-loop optimisation. The classical co-processor varies individual application times of a problem/driver propagator sequence to prepare a state which approximately minimises the problem’s generator. Analytical solutions to choose optimal application times (called parameters or angles) have proven difficult to find, whereas outer-loop optimisation is resource intensive.

We present a novel, compile-time method for determining the cache performance of the loop nests in a program. The cache hit-rates are produced by applying the reference string, determined during compilation, to an architecturally parameterized cache simulator.

The results of the loop program optimizations are presented for different parallel program benchmarks and various processor architectures, such as IBM SP1 RS/6000, the SuperSPARC, and the Intel 1860.

The subsequent chapters extend the latter by including the most popular software development models. Then, based on the V model, the role of verification and validation in the software and controller life cycle is presented, and the test techniques used in the controller validation are given. These test types include: software in the loop, processor in th

Abstract:

The present paper offers an analysis of heat transfer and fluid flow in two phase thermosyphon loop with minichannels. A one-dimensional model of two-phase flow and heat transfer in a closed thermosyphon loop with minichannels was examined. The created general model is based on mass, momentum, and energy balances in the evaporators, rising tube, condensers and the falling tube. The separate two-phase flow model is used in calculations. The numerical results obtained for the selected heater and cooler using the general model of thermosyphon loop indicate that the mass flux increases with increa

Abstract:

A new recursive algorithm for real-time dynamic simulation of mechanical systems with closed kinematic loops is presented. State vector kinematic relations that represent translational and rotational motion are defined to simplify the formulation and to relieve computational burden. Recursive equations of motion are first derived for a single loop multi-body system. Faster than real-time performance is demonstrated for a closed loop manipulator, using an Alliant FX/8 multiprocessor. The algorithm is extended to multi-loop, multi-body systems for parallel processing real-time simulation in comp

Abstract:

In this paper the H∞ robust control technique is applied to design a switched reluctance motor drive where the rotor position sensor provides just six pulses per revolution. A control system analyzer is used to obtain the frequency responses at each design step. To reduce the effect of the inherent phase inductance variations, an H∞ two-degree-of-freedom control scheme is designed in the current-loop of the drive to achieve the demanding time-response specifications. In order to have a good load torque disturbance rejection ability, the H∞ loop shaping procedure is employed to construct a lead
