A Hierarchical Framework for the Management of Virtualized Resources for Multi-Tier Services and Applications in Cloud Computing
Get PDFCloud computing has become a new age technology that has got huge potentials in enterprises and markets. It makes it possible to access applications and associated data from anywhere. Organizations are able to rent resources from the cloud for storage and other computational purposes to reduce cost (operational cost). Further, they can make use of wide access to applications, based on the pay-as-you-go model. Hence there is no need for getting licenses for individual products. However one of the major pitfalls in cloud computing is related to optimization of cloud virtualized resources. Because of the uniqueness of the cloud model,resource allocation is performed with the objective of optimizing computing, communication and storage resources. Many researchers propose different methods of optimizing cloud resources, some of which are the use of soft computing approaches. Many of these optimization algorithms proposed are still under investigation and modification to improve their capabilities in managing well, the computing, communication and storage resources in the cloud. For efficient virtualized resource management in the cloud, the existing (soft computing approaches) resource allocation algorithms are becoming inefficient with the increase inthe size of cloud data. In view of the above challenge,this research therefore proposes Hierarchical Framework of models for the adaptive management of virtualized resources for efficient resource allocation in cloud computing

On-line weft knitted fabric defect detection was tested automatically by analyzing fabric imagescaptured by a digital camera using Gabor wavelets and classification (Identification) these fabric defects to known classes. Wesucceeded to detect weft knitted fabric defects and classify defect’s on the weft circular knitting machine at the same time themachine stops to correct the fabric defect to achieve customer required quantity and quality. As well as we cancel the fabricinspection process that means, saving money, time, manpower which leads to reducing production lead time and cost
Removal of Heavy Metal from Waste Water Using Activated Carbon from Rice Husk
Get PDFAdsorption of heavy metals is a new technology for the treatment of wastewater containing different types of selected heavymetals. This study investigated the adsorption capacities of Pb and Cd onto ARHC and URHC made out of rice husks, availableas agriculture waste. The effect of various parameters such as pH, adsorbent dose, adsorbent concentration, and contact time onthe removal of Pb and Cd by ARHC and URHC were also examined. It was discovered that adsorption capacity decreases with anincrease in pH solution this so because the available Pb and Cd molecules are not able to cover all the exchangeable sites on thebiosorbent. The equilibrium data fitted with Langmuir and Freundlich isotherm models, but best fitted with the Langmuir isotherm model. The adsorption kinetics for this study was best described by the pseudo-second-order kinetics

Significance of Ornamentation in Yoruba Traditional Architecture
Get PDFCulture and tradition are vital constituents of traditional architecture. However, in the period of proliferation and modernism,traditional architecture is fast disappearing in most parts of Africa due to negligence and incredulity of its importance. Reassessment becomes necessary as traditional architecture can be a source of inspiration even in contemporary times. Throughreview scoped literature, this study takes a critical look at how culture affects ornaments of architecture in Nigeria with Yorubaas a case study. This paper explores significance of ornamentation in Yoruba palace architecture. This means the creative objectswithin the old palace (‘afin’) constructed when the city was formed, including the courtyards (‘akodi’) and other structures withinthe palaces. It concludes with attributes of different palace ornamentation with clear direction on key roles in the study palacecultural belief and traditions. Data was sourced from fieldwork, oral interviews and relevant literature. Purposively selectedphotographs of palaces ‘Afin’ are used in discussing the state of the architecture and sculpture objects, therefore raises theenquiry of their connotation for upcoming generations. In other words, ornamentation has a basic statement for which it wascreated (meaning); the mutual concern and relevance of such artifact, form, or object gives it a name, root and status in additionto identity as the material culture of the designing community. The study reveals the benefits of palace ornament to Yorubatradition and culture and the importance of culture and history of people if the memories of their past are celebrated and theircenotaphs and antique places of pride are intact. This paper suggests that elements of palace ornaments like art and heritage architecture in Yoruba palace ornamentation have become a natural occurrenc
