electrochemical impedance spectroscopy (eis) is a suitable and powerful diagnostic testing method for fuel cells (fcs) since it is non-destructive and provides useful information about fc performance and its components. in this study, for the first time, a 500w cascade type 4 cells stack with integrated humidifier, water separator and internal manifolds was designed, fabricated and tested. the ...

Growing amounts of multimedia data (alphanumeric, image, sound and video) are being captured with the increasing deployment of sensors. We present the image stack stream model or view of data as a convenient basis for both querying and visualizing the situation and changes through time of phenomena buried in the multitude of such variety of data. We outline briefly the requirements with motivat...

This paper presents an experimental and theoretical investigation of the causes of corrosion of stack in a cement plant. In this paper, information related to metallic stack failures are given in the form of a case study in Neka Cement Plant, Mazandaran, Iran. Heavy corrosion attacks were observed on the samples of stack. The failure can be caused by one or more modes such as overheating, stres...

Growing amounts of multimedia data (alphanumeric, image, sound and video) are being captured with the increasing deployment of sensors. We present the image stack model or view of data as a convenient way to not only visualize such variety of data but also as a basis for querying it, even if the data is not stored as such. We outline briefly the requirements with example queries, and the recomm...

We describe the mbuf tag API, a mechanism for tagging data as they flow through the network stack. Originally introduced in OpenBSD, mbuf tags were initially intended for use by the IPsec stack. The API has matured enough to be used by several other kernel components, and formed the basis for the FreeBSD mbuf tags. We present the API, discuss its various uses in the OpenBSD network stack, and d...

LDApp is designed as a very modular JavaScript Linked Data stack. A requirement for the modular design was an API to handle the graph data. RDF-Interfaces was the only JavaScript API standard, but lacks store handling and easy management of multiple parsers and serializers. The existing RDF-Interfaces API was extended to cover these use cases. To complete the framework, a JSON-LD integration is...
