Quintet.net is a real-time interactive environment for intermedial composition and performance on local networks as well as the Internet. Since its premiere in 2000, the environment has been used in several large projects connecting players in Europe and the U.S.A., a Munich biennale opera project among them. Quintet.net implements, in a virtual environment, the metaphor of five performers under the control of a conductor, thus dealing with important aspects of symbolic, aural and visual communication among the participants and the network audience. A composition development kit has been added to the environment (which consists of Client, Server, Listener, Conductor and Viewer) to facilitate the development of pieces that take full advantage of the wide continuum between composition and improvisation.

AbstractThis article focuses on the production and dissemination of photographic images by serving US soldiers in Iraq who are photographing their experiences and posting them on the Internet. This form of visual communication – in real time and communal – is new in the representation of warfare; in earlier wars soldiers took photographs, but these were not immediately shared in the way websites can disseminate images globally. This digital generation of soldiers exist in a new relationship to their experience of war; they are now potential witnesses and sources within the documentation of events, not just the imaged actors – a blurring of roles that reflects the correlations of revolutions in military and media affairs. This photography documents the everyday experiences of the soldiers and its historical significance may reside less in the controversial or revelatory images but in more mundane documentation of the environments, activities and feelings of American soldiery at war.

AbstrakJaringan internet yang saat ini di gunakan untuk penyimpanan data atau halaman informasi pada website menjadi rentan terhadap serangan, untuk meninkatkan keamanan website dan jaringannya, di butuhkan honeypot yang mampu menangkap serangan yang di lakukan pada jaringan lokal dan internet. Untuk memudahkan administrator mengatasi serangan digunakanlah pengelompokan serangan dengan metode K-Means untuk mengambil ip penyerang. Pembagian kelompok pada titik cluster akan menghasilkan output ip penyerang.serangan di ambil sercara realtime dari log yang di miliki honeypot dengan memanfaatkan MHN.Abstract The number of internet networks used for data storage or information pages on the website is vulnerable to attacks, to secure the security of their websites and networks, requiring honeypots that are capable of capturing attacks on local networks and the internet. To make it easier for administrators to tackle attacks in the use of attacking groupings with the K-Means method to retrieve the attacker ip. Group divisions at the cluster point will generate the ip output of the attacker. The strike is taken as realtime from the logs that have honeypot by utilizing the MHN.

Purpose The purpose of this study is to develop and assess the real-time multiuser virtual reality (VR) application that can be used in the design review process. In particular, the application was aimed to accommodate the design review meetings conducted among participants who are in different locations, which has become commonplace during the COVID-19 outbreak. Design/methodology/approach This paper presents a methodology for the development of a real-time multiuser immersive VR application, to support remote collaboration during the design review process. The developed application can immerse remote project participants into the same virtual environment and provide virtual face-to-face discussions. An experiment was conducted with 44 university students to investigate the applicability and performance of the developed application by comparing it with the traditional approach. Findings Results indicated that the group of students who used the developed immersive VR application outperformed the group that used the traditional approach. This was measured by the percentage of correctly identified design errors during a building inspection experiment. Originality/value The difficulty of bringing remote stakeholders together in a virtual environment has impeded the implementation of VR technology in the architecture, engineering and construction (AEC) industry. Most research has focused on the improvement of a single user’s experience. Most of the previous multiuser VR studies were conducted in other industries while similar research in the AEC industry is limited. The study presented in this paper contributes to the AEC industry by presenting the development of multiuser immersive VR applications for real-time remote collaboration and the empirical evidence to substantiate its potential benefits.

A network in computers consists of a set of interconnected computers using an appropriate technique. In cloud computing, every client and server is unique and has different processing capability. Each server is independent where resource allocation is an important feature for the system to appear as a single network. So the performance of the system depends on the allocation of work among the servers effectively. It is the combination of various factors like latency, throughput, consistency, reliability, and performance. The concept of dynamic resource balancing can be introduced to efficiently manage the factors to be fulfilled in a distributed network. Every client in the network benefits from dynamic resource balancing. In turn, all tasks benefit from resource balancing. The resource balancing comprises of both physical and logical features. The time, cost, performance must be optimized through resource balancing. The paper describes a model for resource balancing in the system to manage the performance through the Internet in cloud computing. This proposed algorithm can be applied to n-processor dynamic systems. This will prove effective to reduce the server resources

And Performance

In this paper, the control problem of a class I of underactuated mechanical systems (UMSs) is addressed. The considered class includes nonlinear UMSs with two degrees of freedom and one control input. Firstly, we propose the design of a robust integral of the sign of the error (RISE) control law, adequate for this special class. Based on a change of coordinates, the dynamics is transformed into a strict-feedback (SF) form. A Lyapunov-based technique is then employed to prove the asymptotic stability of the resulting closed-loop system. Numerical simulation results show the robustness and performance of the original RISE toward parametric uncertainties and disturbance rejection. A comparative study with a conventional sliding mode control reveals a significant robustness improvement with the proposed original RISE controller. However, in real-time experiments, the amplification of the measurement noise is a major problem. It has an impact on the behaviour of the motor and reduces the performance of the system. To deal with this issue, we propose to estimate the velocity using the robust Levant differentiator instead of the numerical derivative. Real-time experiments were performed on the testbed of the inertia wheel inverted pendulum to demonstrate the relevance of the proposed observer-based RISE control scheme. The obtained real-time experimental results and the obtained evaluation indices show clearly a better performance of the proposed observer-based RISE approach compared to the sliding mode and the original RISE controllers.
