We present two methods for estimating replacement probabilities without using parallel corpora. The first method proposed exploits the possible translation probabilities latent in Machine Readable Dictionaries (MRD). The second method is more robust, and exploits context similarity-based techniques in order to estimate word translation probabilities using the Internet as a bilingual comparable ...

INTRODUCTION The current role of nurses in the management of critically ill patients needing continuous renal replacement therapies is clearly fundamental. The care of these complex patients is typically shared by critical care and dialysis nurses: their precise duties may vary from country to country. METHODS To clarify this issue we conducted a national-level survey at a recent Italian cour...

We study the maintenance of a machine operating under environmental conditions producing shocks affecting the lifetime of the machine. The shocks cause different types of damage depending on their strength and eventually the total failure. The maintenance of the machine is performed by repairs and replacement. The interarrival times of shocks are dependent. We introduce a multidimensional stoch...

To make paper, machines spray wet pulp on a moving screen and extract the water from it by squeezing it between rollers, before drying it using heat and rolling it on reels as finished product. The water extracted in the squeezing process is removed by a continuous roll of fabric called a felt. There are typically three felts on a paper machine. Felts wear out over time, and therefore must be r...

This paper considers the problem of scheduling maintenance actions for identical aircraft gas turbine engines. Each one of the turbines consists of parts which frequently require replacement. A finite inventory of spare parts is available and all parts are ready for replacement at any time. The inventory consists of both new and refurbished parts. Hence, these parts have different field lives. ...

The trend in cache design research is towards finding the single optimum replacement policy that performs better than any other proposed policy by using all the useful criteria at once. However, due to the variety of workloads and system topologies it is daunting, if not impossible, to summarize all this information into one magical value using any static formula. We propose a workload and topo...

Machine maintenance is modeled in the setting of a single-server queue. Machine deterioration corresponds to slower service rates and failure. This leads to higher congestion and an increase in customer holding costs. The decision-maker decides when to perform maintenance, which may be done preemptively; before catastrophic failures. Similar to classic maintenance control models, the informatio...

selecting an appropriate manufacturing machine is a very important and complex problem for firms, which usually have to deal with both qualitative and quantitative criteria. taking into account the differences among machines in terms of cost, speed, quality and after sale services, type and number of machines are important parameters to consider. therefore, the goal of this paper is to propose ...

Ochronosis or black joints disorder is a rare autosomal recessive disorder caused by deficiency of homogentisic acidoxidase. Orthopaedic manifestations are common and mostly involve spine and large joints such as knee and hip.Arthropathy is progressive and will eventually leads to arthroplasty. Not being familiar with this disorder might lead todevastating complications. We present a 57 year-ol...

This paper models a machine replacement and capacity expansion problem as an infinite-horizon linear program. We establish a strong duality result and show that stationary dual prices are optimal, regardless of initial conditions. These prices measure the economic value of owning vintage machinery and thus define depreciation schedules. We present necessary and sufficient conditions for straigh...
