This article analyses the push and pull factors that bring visitors to the Iranian national parks. The study used a structured questionnaire to collect data on these factors and the socio-demographic profile of the visitors. Survey conducted in Boujagh National Park, an area of 3177 hectares located in the north of the Iran, produced 400 questionnaires. The factor analysis identified four push ...

This paper describes a technique called producer-push that enhances the performance of a page-based software distributed shared memory system. Shared data, in software DSM systems, must normally be requested from the node that produced the latest value. Producer-push utilizes the execution history to predict this communication so that the data is pushed to the consumer before it is requested. I...

New technologies enable educators to modify their teaching methods and extend their reach beyond the classroom. One of these methods that can be applied to communicate with students is through the use of push notifications on smartphones. Instead of relying on students to use a spaced learning approach, which is proven to be more efficient than trying to study something in a short period of tim...

Server Push, one of the most promising features of HTTP/2, allows web servers to speculatively send unsolicited web resources to clients. While the mechanism for Push is well defined, policies for effectively utilizing push to maximize page load performance are poorly understood. In this work we investigate the factors that should be considered when implementing a Push policy and combine them t...

A novel single-stage push–pull electronic ballast with high input power factor is presented in this paper. The proposed electronic ballast combines the front-end power-factor corrector and push–pull converter into a single-stage converter. Compared to the single-stage class-D electronic ballast, the proposed circuit does not require an isolated driver. The control of the circuit is easier and t...

A great deal of research has investigated the potential parameters of tactile feedback for virtual buttons. However, these studies do not take the possible effects of feedback latencies into account. Therefore, this research investigates the impact of tactile feedback delays on touchscreen keyboard usage. The first experiment investigated four tactile feedback delay conditions during a number e...
