    Opis:
    Cloud computing is a business model with high degree of flexibility, scalability in providing infrastructure, platform and software as a service over the internet. Cloud promises for easiness and reduced expense to service providers and consumers. However, a lack of trust between these two stakeholders has hindered the universal accep¬tance of cloud for outsourced services. In this paper, a fuzzy based trust management system is proposed to facilitate cloud consumers in identifying trustworthy providers. The performance of the proposed system is validated through a simulation using CloudAnalyst and Simulink.

    Opis:
    In this paper we propose a new method of scheduling the distributed applications in cloud environment according to the High Performance Computing as a Service concept. We assume that applications, that are submitted for execution, are specified as task graphs. Our method dynamically schedules all the tasks using resource sharing by the applications. The goal of scheduling is to minimize the cost of resource hiring and the execution time of all incoming applications. Experimental results showed that our method gives significantly better utilization of computational resources than existing management methods for clouds.

    Opis:
    The use of ‘proper energy computation system’ is the best method to investigate the problem of energy deficiency, since energy consumption in computational resources is proportional with the work load in the applied program. Also, the best method to improve the use of resources and decrease in energy consumption is dynamic integration of virtual machines which can be a base for the integration of resources in independent systems through virtualization technology, so that it is possible to use resources and equipment for long time and consequently assuring quicker return of investment. Today, grid computation is a new technology connecting heterogeneous computational resources to each other; thus, this structure operates as an individual and integrated virtual machine. Then, it is possible to implement very complex applied programs requiring high processing capacity and huge amount of input data on this virtual machine. In this regard, the purpose of this study is to present an approach for resource management in grid environments using PSO and Genetic algorithms, and also ants colony to find the location of virtual machines.

    Opis:
    Artykuł prezentuje system zdalnego sterowania i pomiarów rozproszony w sieci Internet. System składa się z urządzeń końcowych (instalowanych w zdalnych lokalizacjach) oraz infrastruktury informatycznej (IT). Technologia wirtualizacji pozwala na wykorzystanie zaawansowanej infrastruktury przy zachowaniu niskich kosztów. Przykłady instalacji obejmują monitorowanie wymiennikowni ciepła (m.in. zdalny odczyt liczników energii), czy zdalne pomiary meteorologiczne (za pośrednictwem sieci GSM).
    The paper presents a SCADA system distributed in the Internet. The system consists of endpoint devices (installed in the remote localizations) and an information technology (IT) infrastructure. The virtualization technology allows maintaining a low cost of an advanced IT infrastructure. The cost is proportional to the used computing power and each user does not require an individual, professional server. Moreover, the devices communicate with the server only to exchange recently acquired data and control commands. All data storage is done by a virtual server. Thus, the cost of data transfer in case of the GSM devices is very low (data is transported to the server once, and there is no additional data access cost). Moreover, the server provides flexible interfaces for integration with other SCADA and IT systems. The endpoint devices are very simple (no advanced data processing), which results in low fixed costs of installation. Data exchange between the devices and the virtual server is secured. Example installations cover monitoring of a heat power exchange station (along with reading of remote M-bus energy meters) or a meteo station. The system architecture is shown in Fig. 4.

    Opis:
    Web caching is a crucial technology in Internet because it represents an effective means for reducing bandwidth demands, improving web server availability and reducing network latencies. However, Web cache cluster, which is a potent solution to enhance web cache system’s capability, still, has limited capacity and cannot handle tremendous high workload. Maximizing resource utilization and system capability is a very important problem in Web cache cluster. This problem cannot be solved efficiently by merely using load balancing strategies. Thus, along with the advent of cloud computing, we can use cloud based proxies to achieve outstanding performance and higher resource efficiency, compared to traditional Web proxy cache clusters. In this paper, we propose an architecture for cloud based Web proxy cache cluster (CBWPCC) and test the effectiveness of the proposed architecture, compared with traditional one in term of response time ,resource utilization using CloudSim tool.

    This paper describes many types of public cloud computing and problem with cloud computing security. Cloud computing is the use of computing resources that are delivered as a service over a network. Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar. The paper presents the several years' experience of the AMR (Automated Meters Reading) system operation based on a private cloud. AMR projects are successfully used by numerous local and national utilities but it was one of the first projects based on cloud technology. This system AMR was implemented in a utility company. The computer system has been working commercially since 2008. Users have to connect to server using Remote Desktop Connection. It was a new solution for the users. They were accustomed to the fact that all the programs they had installed on own PC. The past experience show that the cloud computing is a very forward-looking technology which can be used in systems AMR/AMI (Advanced Metering Infrastructure).

    Opis:
    The paper presents an innovative data classification approach based on parallel computing performed on a GPGPU (General-Purpose Graphics Processing Unit). The results shown in this paper were obtained in the course of a European Commission-funded project: “Research on large-scale storage, sharing and processing of spatial laser data”, which concentrated on LIDAR data storage and sharing via databases and the application of parallel computing using nVidia CUDA technology. The paper describes the general requirements of nVidia CUDA technology application in massive LiDAR data processing. The studied point cloud data structure fulfills these requirements in most potential cases. A unique organization of the processing procedure is necessary. An innovative approach based on rapid parallel computing and analysis of each point’s normal vector to examine point cloud geometry within a classification process is described in this paper. The presented algorithm called LiMON classifies points into basic classes defined in LAS format: ground, buildings, vegetation, low points. The specific stages of the classification process are presented. The efficiency and correctness of LiMON were compared with popular program called Terrascan. The correctness of the results was tested in quantitive and qualitative ways. The test of quality was executed on specific objects, that are usually difficult for classification algorithms. The quantitive test used various environment types: forest, agricultural area, village, town. Reference clouds were obtained via two different methods: (1) automatic classification using Terrascan, (2) manually corrected clouds classified by Terrascan. The following coefficients for quantitive testing of classification correctness were calculated: Type 1 Error, Type 2 Error, Kappa, Total Error. The results shown in the paper present the use of parallel computing on a GPGPU as an attractive route for point cloud data processing.

    W artykule przedstawiono mobilny system tworzenia przestrzennej dokumentacji semantycznej. Zaproponowano nową metodę filtracji oraz rejestracji danych wykorzystującą obliczenia równoległe (NVIDIA FERMI). Opracowany system informatyczny umożliwia gromadzenie danych przestrzennych z wykorzystaniem geodezyjnego systemu pomiarowego 3D oraz pozwala na etykietowanie obiektów. Tworzona mapa semantyczna jest dostępna z poziomu dowolnego urządzenia mobilnego (laptop, smartphone, tablet).
    In this paper a new system for creating spatial semantic documentation is shown. We define semantic documentation as a result of integrating semantic mapping with a mobile 3D geodetic scanning system and a cloud computer system. This approach is possible by using semantic mapping State of the Art [2], modern scanning techniques [3] and parallel computing [4]. The main task of the system is representing the environment with concepts of objects highlighted in it. The results are distributed in a cloud. The phases of system operation are shown in Fig. 1. Each phase is described in detail in consecutive sections of the paper. Section 1 describes the thought process behind the system and data acquisition with a ZF 5010 laser scanner. In Section 2 a CUDA(NVIDIA FERMI) enhanced scan filtration method is shown. The next step of data preparation, merging of 3D point clouds, is described in Section 3. Section 4 concentrates on manual environment conceptualization (map with object concepts is shown in Fig. 4). Semantic documentation distribution and sharing are described in Section 5. The results can be shown on any PC, tablet, smartphone or smartTV device, by using SaaS(Software as a Service) approach and Citrix system. The paper finalizes with conclusions and plans for further system development. The system is a new approach to sharing information about the environment and it may be applied i.e. in Crisis Management for coordinating complicated rescue operations, in interior design and cataloguing etc.
