Deploying Trusted Cloud Computing for Data Intensive Power System Applications
(2015 50th International Universities Power Engineering Conference (UPEC), 2015-09-01) Sule, Mary-Jane; Li, Maozhen; Taylor , Gareth A; Furber, Simon
Cloud computing deployment is gaining popularity among sensitive mission-critical sectors like the energy sector. Cloud computing can provide cost effective scalable deployment of ICT services and infrastructure to the energy sector. However, the security, confidentiality and integrity of data are paramount and are of great concern to the energy sector. This paper presents the deployment of trusted Cloud computing for mission critical applications in the energy sector. The research presented in this paper simplifies the integration of trusted platform module based integrity measurement into commodity cloud infrastructure by eliminating the need for “custom” software and patches; it also enhances instance-level security by including a distributed file and directory integrity checker for added security. The deployment of trusted cloud computing using the Eucalyptus Cloud software on server-grade hardware is discussed, as well as the results of a comparative evaluation of the additional overhead in instance creation/start-up based on a simulation of low, medium and high security settings. The trusted cloud computing infrastructure is also currently available for deployment and testing by power system application developers and users.
A Conceptual Framework of Deploying Cloud IaaS in Higher Educational Institutions
(IEEE Third International Conference on Cloud Computing Technology and Science, 2011-05-29) Sule, Mary-Jane
All cloud services require the fundamental
layer known as Infrastructure as a service (IaaS).
Clouds have the benefit of being cost effective, while
improving productivity. This paper is focused on a
proposed conceptual model for deploying Cloud IaaS
in Higher Educational Institutions in Africa with
Nigeria as a Case Study.
As an IT professional working in the educational
sector in this region the investigator has experience the
gains of ICT in both learning and dissemination of
information
Though the focus of this research is on Nigeria, the
resulting structure can be implemented across the
African continent and other developing countries.
Trust Modeling in Cloud Computing
(IEEE Symposium on Service-Oriented System Engineering, 2016) Sule, Mary-Jane; Li, Maozhen; Taylor, Gareth
Though, cloud computing continues to gain popularity and has enormous economic gains, the perceived lack of trust from end-users accessing these resources continues to hinder its full deployment, usage and adoption. Tradition security and privacy controls continue to be implemented on cloud but due to its fluid and dynamic nature, research work in the area of end-user attestable trust evaluation of the cloud platform seem to be limited. With the nature of cloud, service level agreements are not enough, the user would want a transparent system with a traceability facility that allows the user to determine the relationship between varying trust relationships across the cloud layers, components, algorithms and applications especially at large scale. This paper presents some security mechanisms that enable cloud service end users to evaluate the trust level of various cloud services and resources. These mechanisms are evaluated based on fuzzy theory on a Eucalyptus cloud platform.
Prevalence of some metals in native and branded factory-based lager beers within Jos metropolis
(2015-12) S Y. Gazuwa; J D Dabak; G A Ubom
Ethyl alcohol toxicity is implicated in disease conditions such as cirrhosis, hepatitis and these
ailments among drinkers are high even after seeking medical attention. This work was therefore undertaken to
analyse for zinc, iron, lead, cadmium, and manganese as contaminants in samples of beers. Atomic absorption
spectrophotometric technique was applied to achieve the objectives of the work. Although the results indicated
contamination of the samples with the metals, the magnitude of the contamination was higher in native, relative
the factory-based lager beers. In burukutu, the level of Zn was above that in pito and goskolo. Compared to the
maximum reference levels in drinking water, level of Fe was lower just as for Pb (P >0.05). Goskolo had the
highest burden of Cd followed by burukutu and pito. In burukutu and pito, Mn was high (P =0.05) compared to
reference values. In the case of the factory-based lager beers, levels of Zn, Mn and Fe were below the reference
values for all the brands. Levels of Cd and Pb were above the maximum values (P =0.05). In Guinness, Harp,
and Star, the content of Cd and Pb were significantly (P =0.05) above reference values for drinking water, but
other metals were not significant (P >0.05). Extent of contamination with Pb was highest in Gulder (P=0.05).
Alcoholic drinks are contaminated with metals whose toxicities could aggravate ailments, usually ascribed to
alcohol alone, in drinkers.
Inflammatory breast cancer: Still a diagnostic dilemma
(Journal of Surgery, 2014-06-10) M. A. Misauno; W. M. Isichei
Background: Inflammatory breast cancer (IBC) is a rapidly progressive disease associated with high mortality
in developing countries. The patients are managed for mastitis’s first and IBC becomes a diagnosis of exclusion after failed
response to appropriate antibiotic therapy. This study was aimed at evaluating the outcome of management of IBC in North
central Nigeria. Patients and method: This was a prospective analysis of consecutive patients presenting with breast cancer
at the Abubakar Tafawa Balewa University teaching hospital Bauchi (ATBUTH) from January 2011 to December 2012.
Results: A total of 52 breast cancers were managed, mean age was 31+/- 2years with an age range of 29 -33 years. There
were 51 females and 1male (f: m = 51:1). IBC accounted for 9(17.3 %) of the breast cancers. Conclusion: IBC is
frequently misdiagnosed as mastitis for various reasons and a high index of suspicion is required to clinch the diagnosis.
