Within the paper, a novel approach for the reconstruction of geometric details of building façades is presented. It is based on 3D point clouds from terrestrial laser scanning. By a segmentation process, the approximate boundaries of the windows are detected and a cell decomposition of the façade is created. A classification of the cells determines a symmetric window arrangement of maximum like...

Cloud computing represents a major shift in information systems architecture, combining both new deployment models and new business models. Rapid provisioning, elastic scaling, and metered usage are essential characteristics of cloud services, and they require cloud resources with these same characteristics. When cloud services depend on commercial software, the licenses for that software becom...

Knowing the metrics related to cloud is very critical to enhance the performance of the cloud. To learn the metrics related to cloud like the infrastructure, structure and functionality of the cloud systems many models were described. This paper lists some of the technical models related to the cloud computing that enhances the cloud performance. The models that are discussed focusses on some m...

The FRESCO (Fast Retrieval Scheme for Clouds from the Oxygen A-band) algorithm has been used to retrieve cloud information from measurements of the O2 Aband around 760 nm by GOME, SCIAMACHY and GOME2. The cloud parameters retrieved by FRESCO are the effective cloud fraction and cloud pressure, which are used for cloud correction in the retrieval of trace gases like O3 and NO2. To improve the cl...

Cloud computing is a recent computing paradigm that represents a fundamental change of information commu- nication technology (ICT) services and Cloud services continue to grow rapidly with increasing functionality and more users. As a result of this growth, it is a critical issue to select a suitable Cloud service which meets all the business strategies and the objectives of firms. This paper ...

Given the costs associated with a cloud infrastructure, dynamic scheduling of virtual machines (VMs) can significantly lower costs while providing an acceptable service level. We develop a series of forecasting models for predicting demand for VMs in a cloud-based software used as a SaaS. These models are then used in a periodic-review provision model which determines how many VMs should be pro...

Satellite-retrieved aerosol optical properties have been extensively used to estimate ground-level fine particulate matter (PM2.5) concentrations in support of air pollution health effects research and air quality assessment at the urban to global scales. However, a large proportion, ~70%, of satellite observations of aerosols are missing as a result of cloud-cover, surface brightness, and snow...

Control is imperative to effective service delivery. Monitoring the control parameters of IT infrastructure elements thereof is of paramount importance both for IT and IT-enabled businesses. These parameter-values need to be captured from service delivery environment of any IT-enabled business. The new-age IT infrastructure models are promising with cloud and virtualization technology options a...
