Cloud computing has recently emerged in the landscape of Information Technology as a compelling paradigm for managing and delivering services over the Internet in a performanceand cost-effective way. However, its development is still at its infancy, with many issues worthy to be investigated. In this chapter, we analyze the problem of service level provisioning and the possible strategies that ...

The performance of many computer vision methods depends on the quality of the local features extracted from the images. For most methods the local features are extracted independently of the task and they remain constant through the whole process. To make features more dynamic and give models a choice in the features they can use, this work introduces a set of intermediate features referred as ...

A new and versatile cloud screening algorithm (CLoud and Aerosol Unbiased Decision Intellectual Algorithm, CLAUIDA) bas been developed for multi-channel imagers on board satellites, and is applied to the operational procedure for GOSAT/CAI (a 4-channel imager) cloud screening. CLAUDIA consists of many threshold tests to deal with various cloud types on various surfaces, and is designed to aim a...

because of the role of climate parameters in climate change and improve the efficiency of climate and rainfall prediction models, the study of these parameters are very important in the world. the study of clouds have special important, because the clouds make connection between the synoptic patters and surface climate conditions and any change in its properties, can start a chain reaction in o...

Cloud computing is a technological advancement in the arena of computing and has taken the utility vision of computing a step further by providing computing resources such as network, storage, compute capacity and servers, as a service via an internet connection. These services are provided to the users in a pay per use manner subjected to the amount of usage of these resources by the cloud use...

Using the satellite-infrared-based Simple Convective Aggregation Index (SCAI) to determine the degree of aggregation, 5 years of CloudSat-CALIPSO cloud profiles are composited at a spatial scale of 10 degrees to study the relationship between cloud vertical structure and aggregation. For a given large-scale vertical motion and domain-averaged precipitation rate, there is a large decrease in anv...

Cloud is an on-demand computing service which provides a dynamic environment for end users to assure Quality of Service (QoS) on data for its confidentiality in cloud data centers. A set of information from a cloud database with a high security level accessing data is said to be Confidentiality. The proposed research work is a new cloud data security model, A Neural Data Security Model (NDSM) t...

Cloud infrastructures needs to become more smarter and dynamic in managing resources, requiring new solutions and tools to cope with processes of configuration and reconfiguration, automatic scaling, elastic computing and healthiness control. This paper presents a Smart Cloud solution for automatically managing cloud infrastructures, and programming the monitoring aspects directly from the conf...

This study assessed the technical effi ciency of family poultry production in NigerDelta, Nigeria. The technical effi ciency estimate shows that the technical effi ciency of family poultry ranges between 0.09 and 0.63, with mean of 0.22. This indicates that on the average, the respondents are 22% effi cient in the use of combination of their inputs. The elasticity estimate of 12.29 indicates th...
