Isobaric expansion (IE) engines can directly convert heat into mechanical energy, making them particularly attractive for applications such as vapor-driven pumps and compressors. A recent initial assessment investigating the utilization of IE reciprocating compressors has revealed that vapor use efficiency is inherently low in case simplest direct-acting compressor designs. Based on this analys...

Abstract The NP-complete Vertex Cover problem asks to cover all edges of a graph by small (given) number vertices. It is among the most prominent graph-algorithmic problems. Following recent trend in studying temporal graphs (a sequence graphs, so-called layers, over same vertex set but, time, changing edge sets), we initiate study Multistage . Herein, given graph, goal find for each layer and ...

Process flexibility, whereby a production facility can produce multiple products, is a critical design consideration in multiproduct supply chains facing uncertain demand. The challenge is to determine a cost-effective flexibility configuration that is able to meet the demand with high likelihood. In this paper, we present a framework for analyzing the benefits from flexibility in multistage su...

It is shown that the model of twoor multistage programming undi^r risk results from the application of the principle of dynamic planning* in special structured dynamic decision situations under risk. By u ^ing this property, some characteristics of the solution set of dynamic planning problems will be derived. *This principle is well known and discussed as "flexible Planung" in the German manag...

For implementing data analytic tools in real-world applications, researchers face major challenges such as the complexity of machines or processes, their dynamic operating regimes and the limitations on the availability, sufficiency and quality of the data measured by sensors. The limits on using sensors are often related to the costs associated with them and the inaccessibility of critical loc...

Improving the product reliability is the main concern in both manufacturing and service processes which is obtained by monitoring the reliability-related quality characteristics. Nowadays, products or services are the result of processes with dependent stages referred to as multistage processes. In these processes, the quality characteristic in each stage is affected by the quality characterist...

Multistage successive interference cancellation (SIC) and multistage parallel interference cancellation (PIC) are compared under two different realistic dual rate asynchronous DS-CDMA schemes. The effect of power control and imperfect channel side information are also considered. Multistage SIC outperforms singleor multi-stage PIC for any conditions considered.
