The FIRBACK (Far InfraRed BACKground) survey represents the deepest extensive 170 μm images obtained by the ISO satellite. The sources detected comprise about 10% of the Cosmic IR Background (CIB) seen by COBE, and, importantly, were observed at a wavelength near the peak of the CIB. Detailed follow-up of these sources should help pin down the redshifts, Hubble types, and other properties of th...

Due to the dynamic nodes’ movement and their interaction, it is challenged to represent, discover and exchange location information in a ubiquitous environment. In this paper, we present a new approach to location information awareness that organizes the format of nodes’ location information and maintains the communication between direct nodes in a ubiquitous environment. The structure of Conte...

In this paper, we introduce a new method to represent, discover and share context information in a mobile ad hoc networking environment. The structure of the context information has been defined in a repository structure called CiB. The context information is manipulated to implement context exchange via a communication protocol. The protocol has been simulated in NS-2, where high discovery suc...

In this paper, we present a new approach to location information awareness that organizes the format of nodes’ location information and maintains the communication between direct nodes in a ubiquitous environment. The structure of the Context information Base (CiB) and Context information Communication protocol (CiComm) is manipulated to implement the proposed features. The protocol has been si...

This paper examines the development of a Functional Model which will provide a unique framework to enable the objective identification, comparison and appraisal of procurement systems globally. The paper illustrates how the use of existing classification criteria for building procurement systems (CIB 1991) is uninformative in the context of an international investigation, since account is not t...

Cryptocurrency has attracted widespread criticism for its exploitative logics that consume resources and trap unwitting investors into highly volatile, unregulated markets with worsening wealth inequality. A key factor in the rise of crypto trading is social media, where an ecosystem spammers, grifters, ‘crypto influencers’ celebrities such as Elon Musk amplify hype generate public interest. Wh...
