For many manufacturing companies, after-sales service is an increasingly important part of the business and is more complex than manufacturing products. Unlike products it is not possible to produce services in advance and inventory these for future consumption. Instead an unpredictable event such as a machine failure triggers a need for manufacturing of parts for replacement and allocation of ...

We present Fashion-MNIST, a new dataset comprising of 28 × 28 grayscale images of 70, 000 fashion products from 10 categories, with 7, 000 images per category. The training set has 60, 000 images and the test set has 10, 000 images. Fashion-MNIST is intended to serve as a direct dropin replacement for the original MNIST dataset for benchmarking machine learning algorithms, as it shares the same...

The power law process has proved to be a useful tool in characterizing the failure process of repairable systems. This paper presents a procedure for detecting and estimating a mixture of conforming and nonconforming systems. The test of a mixture, based on a simple likelihood ratio, is illustrated with truncated failure data for copy machines. Bootstrap methods are used to gauge the estimation...

Prior work, including our own, shows that application performance in garbage collected languages is highly dependent upon the application behavior and on underlying resource availability. We show that given a wide range of diverse garbage collection (GC) algorithms, no single system performs best across programs and heap sizes. We present a Java Virtual Machine extension for dynamic and automat...

While the plethora of artificial biomedical applications is enriched and combined with the possibilities of artificial intelligence, bioinformatics and nanotechnology, the variability in the ideological use of such concepts is associated with bioethical issues and several legal aspects. The convergence of bioethics and computer ethics, attempts to illustrate and approach problems, occurring by ...

This paper analyzes a connection between risk-sensitive and minimax criteria for discrete-time, nite-states Markov Decision Processes (MDPs). We synthesize optimal policies with respect to both criteria, both for nite horizon and discounted in nite horizon problem. A generalized decision-making framework is introduced, which includes as special cases a number of approaches that have been consid...

This paper describes CILIX, a compact and powerful implementation of a CIL virtual machine working on resource-poor wireless sensor nodes. CILIX can process CIL programs on a device that has such limited computational resources as an 8-bit/16-bit CPU, 32-KB program memory, and 4-KB RAM. It provides many useful functions for a sensor node, including an I/O manager with UDP, FAT 32, thread contro...

The precise determination of worst-case execution times (WCETs) for programs is mostly being performed on linked executables, since all needed information and all machine parameters influencing cache performance are available to the analysis. This paper describes how to perform a component-wise prediction of the instruction-cache behavior guaranteeing conservative results compared to an analysi...

Executive Summary. The Sequoia AVC Advantage is a direct-recording electronic (DRE) voting machine used in New Jersey, Pennsylvania, and other states. I. The AVC Advantage 9.00 is easily “hacked,” by the installation of fraudulent firmware. This is done by prying just one ROM chip from its socket and pushing a new one in, or by replacement of the Z80 processor chip. We have demonstrated that th...

The area of maintenance has for long not been simple replacement of a part after its failure. The trend in maintenance today is to keep up with the development of computer technologies, which are increasingly being used. The education in the field of maintenance should also take this direction. This paper points to such an orientation, its goal being to point at the possibility of applying mode...
