To achieve its goal to be user-driven, building the Global Earth Observation System of Systems (GEOSS) must be guided by a set of explicitly known user needs. At the core of GEOSS is the GEOSS Common Infrastructure (GCI), which includes registries that enable users of Earth observations to search, discover, access, and use the data and services available through GEOSS. Three of these registries...
the study was designed to investigate the comparative analysis of agricultural credit users and non-users among cassava farmers in ohafia local government area of abia state. a sample of 50 credit users and 50 non-credit user cassava-based farmers were selected by multistage random sampling technique. data were collected with a well structured questionnaire administered to a total of 100 random...
Privacy of users in P2P networks goes far beyond their current usage and is a fundamental requirement to the adoption of P2P protocols for legal usage. In a climate of cold war between these users and anti-piracy groups, more and more users are moving to anonymizing networks in an attempt to hide their identity. However, when not designed to protect users information, a P2P protocol would leak ...
We examine a well known confidentiality requirement called noninterference and argue that manysystems do not meet this requirement despite maintaining the privacy of its users. We discussa weaker requirement called incident-insensitive noninterference that captures why these systemsmaintain the privacy of its users while possibly not satisfying noninterference. We extend thisreq...
It is widely recognised that ergonomists must contribute during needs analysis. However, few studies have investigated the specific contributions of ergonomists at this stage of the design process. In this study, this contribution is studied through the requirement document produced by the design team. For each requirement, the source (i.e. who formulated the requirement), justification (why th...
nowadays, a lot of natural resource co-management plans due to lack of attention to stakeholders’characteristics and position in network of social relationships have failed. actors or key personnel’srecognition has been one of administrative requirement of natural resources co-management plans.the most influential actors in environmental decisions making can be identified based on stakeholdersa...
Mobility of users, transmission of signals through open-air, the requirement of low power consumption by mobile users and smaller data storage area limitation in mobile equipment make mobile wireless networks more vulnerable to security threats like eavesdropping and unauthorized access. This paper proposes a new set of security protocols to enhance the access and data security features of GSM ...
I thank Dean Martin for his very flattering introduction. I thank the College for bestowing a chair to me and the Mathematics Department for providing a wonderful atmosphere for my work. I thank Don Lewis and my current and former colleagues for their support. I take this opportunity to also thank my family, friends, and collaborators. My mathematical horizon has widened considerably after join...
We derive diierent representations of compact QED xed to Lan-dau gauge by the lattice Faddeev-Popov procedure. Our analysis nds that (A)Nielsen-Olesen vortices arising from the compactness of the gauge-xing action are quenched , that is, the Faddeev-Popov determinant cancels them out and they do not innuence correlation functions such as the photon propagator; (B)Dirac strings are responsible f...
Towards Resource Allocation Algorithm in Opportunistic Relaying Cooperative UWB Communication System
A novel communication system named “OR cooperative UWB” is proposed by bringing OR (Opportunistic Relaying) to UWB system. Particularly, the exact and closed-form symbol error rate (SER) expression is derived firstly in this paper. In order to maximize the capacity considering fairness between users, a definition of equivalent mean channel gain is given, and a joint resource allocation algorith...
