چکیده

In general, building and validating a certification path connecting a trust anchor to a target can be a very timeconsuming process. As such, any optimizations are valuable. Certification paths are commonly built from the target to the trust anchor (“building in the forward direction”) or from the trust anchor to the target (“building in the reverse direction”). This paper presents a comparison of these two approaches, analyzes the advantages and disadvantages of each approach, and concludes that building in the reverse direction is often more effective than building in the forward direction.

A Flexible Integrated Forward/ Reverse Logistics Model with Random Path-based Memetic Algorithm

Due to business and environmental issues, the efficient design of an integrated forward/reverse logistics network has recently attracted more attention from researchers. The significance of transportation cost and customer satisfaction spurs an interest in developing a flexible network design model with different delivery paths. This paper proposes a flexible mixed-integer programming model to ...

Error Modeling for TCP Simulations

This work focuses on the implications for TCP performance with respect to two broad characteristics of error modeling. First, we consider rate-based error models vs. temporal error models. We show that it is difficult to confidently assess the impact of improvements to existing protocols or the performance gains of new protocols under a ratebased model. Second, we consider error models that “sy...

Reverse Shoulder Arthroplasty is Superior to Hemiarthroplasty for Cuff Tear Arthropathy with Preserved Motion

Background: It is unclear whether hemiarthroplasty (HA) or reverse shoulder arthroplasty (RS) are superior for patientswith cuff tear arthropathy (CTA) and preserved preoperative motion (elevation >90˚).Methods: This was a retrospective, single institution study. Patients who underwent RSA or HA for CTA were included ifthey had preserved preoperative motion with a minimum of 2...

Considering chain to chain competition in forward and reverse logistics of a dynamic and integrated supply chain network design problem

In this paper, a bi-objective model is presented for dynamic and integrated network design of a new entrant competitive closed-loop supply chain. To consider dynamism and integration in the network design problem, multiple long-term periods are regarded during planning horizon, so that each long-term period includes several short-term periods. Furthermore, a chain to chain competition between t...

XPath: Looking Forward

The location path language XPath is of particular importance for XML applications since it is a core component of many XML processing standards such as XSLT or XQuery. In this paper, based on axis symmetry of XPath, equivalences of XPath 1.0 location paths involving reverse axes, such as ancestor and preceding, are established. These equivalences are used as rewriting rules in an algorithm for ...
