Fixed point theorems for multivalued maps via new auxiliary function

2016

We introduce a contractive condition involving new auxiliary function and prove a fixed point theorem for closed multivalued maps on complete metric spaces. An example and an application to integral equation are given in support of our findings.

A fixed point theorem for G-monotone multivalued mapping with application to nonlinear integral equations

2017

We extend notion and theorem of [21] to the case of a multivalued mapping defined on a metric space endowed with a finite number of graphs. We also construct an example to show the generality of our result over existing results. Finally, we give an application to nonlinear integral equations

Elective surgery system strengthening: development, measurement, and validation of the surgical preparedness index across 1632 hospitals in 119 count…

2022

© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: The 2015 Lancet Commission on global surgery identified surgery and anaesthesia as indispensable parts of holistic health-care systems. However, COVID-19 exposed the fragility of planned surgical services around the world, which have also been neglected in pandemic recovery planning. This study aimed to develop and validate a novel index to support local elective surgical system strengthening and address growing backlogs. Methods: First, we performed an international consultation through a four-stage consensus process to develop a multidomain index for hospital-level assess…

On the existence of bounded solutions to a class of nonlinear initial value problems with delay

2017

We consider a class of nonlinear initial value problems with delay. Using an abstract fixed point theorem, we prove an existence result producing a unique bounded solution.

Towards Personalization of Peer Review in Learning Programming

2017

Peer review is one of the effective processes for sharing knowledge and improving overall learning performance. This became more popular by the use of ICT. However, it is challenging to implement peer review in learning programming languages due to the complexity of the subject matter. A group of peer reviewers may have different overall performance but similar weaknesses on a given aspect of the programming tasks. Hence, they may not be able to help each other to address individual needs. In this paper, we present a personalized approach to peer review with consideration to criteria based assessment and individual performance on specific programming tasks. This is achieved using a novel pe…
