This paper attempts to construct an efficient evaluation for a shipping industry with financial indicators, because sometimes non-financial indicators are difficult to obtain and are doubtful or untrustworthy. So financial indicators are an important method to evaluate performance. A financial statement is audited by CPA and it is easy to gather, so we do not doubt its trustworthiness. The main...

We present a new twist to the Beowulf cluster — the Bladed Beowulf. In contrast to traditional Beowulfs which typically use Intel or AMD processors, our Bladed Beowulf uses Transmeta processors in order to keep thermal power dissipation low and reliability and density high while still achieving comparable performance to Inteland AMD-based clusters. Given the ever increasing complexity of tradit...

In an ad hoc network, all communication is done over wireless media, typically by radio through the air, without the help of wired base stations. Since direct communication is allowed only between adjacent nodes, distant nodes communicate over multiple hops. The quality-of-service (QoS) routing in an ad hoc network is difficult because the network topology may change constantly, and the availab...

The process of designing building automation networks is a very challenging task due to the inherent complexity. During the design process performance evaluation is essential for high reliability and cost efficiency. Therefore, no tool is available up to now, although in other fields of research sophisticated methods for analyzing the system performance exist. In this paper we introduce a metho...

T he idea of green high-performance computing (HPC) has been gaining traction over the past fi ve years. In November 2008, the Green 500 list (www.green500.org) was introduced to “raise awareness about power consumption, promote alternative total cost of ownership performance metrics, and ensure that supercomputers only simulate climate change and not create it.” The Green 500 lists the world’s...

this paper considers the fuzzy inventory model for deteriorating items for power demand under fully backlogged conditions. we define various factors which are affecting the inventory cost by using the shortage costs. an intention of this paper is to study the inventory modelling through fuzzy environment. inventory parameters, such as holding cost, shortage cost, purchasing cost and deteriorati...

We consider the activity-based costing situation, in which for each of several comparable operational units, multiple cost drivers generate a single cost pool. Our study focuses on published data from a set of property tax collection offices, called rates departments, for the London metropolitan area. We define what may be called benchmark or most efficient costs per unit of driver. A principle...

Autonomous vehicles are expected to play a key role in the future of urban transportation systems, as they offer potential for additional safety, increased productivity, greater accessibility, better road efficiency, and positive impact on the environment. Research in autonomous systems has seen dramatic advances in recent years, due to the increases in available computing power and reduced cos...

conclusion the technical performance of pet scan is significantly higher than similar technologies for staging and treatment of nsclc. in addition, it might slightly improve the treatment process and lead to a small level of increase in the quality adjusted life year (qaly) gained by these patients making it cost-effective for the treatment of nsclc. results the total annual running cost of a p...

ultra-endurance mountain running has become extremely popular in recent years, and the energy cost is one of the factors that influence the final performance. the aim of this study was to determine if the energy cost of uphill running (uphill cr) can be calculated from level cr (energy cost of running in mlo2.kg-1.mn-1) in a heterogeneous group of mountain ultra-endurance runners using the di p...
