Haptic Sensation

Use of force feedback, or haptics, has increased the realism of virtual reality simulation systems over the last few years. In this research we propose a framework for the communication of haptic sensation in a shared environment over the Internet for developing novel manufacturing training system. This framework allows re-experiencing the sensation at geographically remote location by transmitting the haptic information over a TCP/IP network. We call this Tele-haptics. Using Tele-haptics, we propose a system where we can capture skill sets commonly associated with complex tasks such a die and tool polishing and communicate this to trainee over the internet. The trainee, using a Phantom Haptic system, can experience the process of polishing based on the master’s input. The framework for haptic communication is experimentally evaluated. The results of the experimental evaluation suggest that it is possible to transmit and recreate haptic features such as geometry and force characteristics.

This paper proposes a passivity theorem on the basis of energy concepts to study the stability of force feedback in a virtual haptic system. An impedance-passivity controller (IPC) was designed from the two-port network perspective to improve the chief drawback of haptic systems, namely the considerable time required to reach stability if the equipment consumes energy slowly. The proposed IPC can be used to achieve stability through model parameter selection and to obtain control gain. In particular, haptic performance can be improved for extreme cases of high stiffness and negative damping. Furthermore, a virtual training system for one-degree-of-freedom sticking was developed to validate the experimental platform of our IPC. To ensure consistency in the experiment, we designed a specialized mechanical robot to replace human operation. Finally, compared with basic passivity control systems, our IPC could achieve stable control rapidly.

At the present time the smart technology enhanced to be utilized for the human life in many elds, especially in the houses. The building automation experienced a rapid growth in techniques and methods to provide an advanced management for operational advantages in buildings and develop the equipment in the houses to the consumption of energy and operation. When the KNX system has been developed to be the most important building automation, the ethernet system has evolved to be global communication system and use it as automation system. Among the various technological developments is IoT, which is the essential development the future achievement via the internet techniques, Meanwhile the different available communication mediums of KNX and the need of utilizing IP network in compiling extensive areas of KNX has led us to conduct this comparison.

Network Traffic Monitoring

The current technology is changing rapidly, with the significant growth of the internet technology, cyber threats are becoming challenging for IT professionals in the companies and organisations to guard their system. Especially when all the hacking tools and instructions are freely available on the Internet for beginners to learn how to hack such as stealing data and information. Tic Timor IP is one of the organisations involved and engaged in the data center operation. It often gets attacks from the outside networks. A network traffic monitoring system is fundamental to detect any unknown activities happening within a network. Port scanning is one of the first methods commonly used to attack a network by utilizing several free applications such as Angry IP Scan, Nmap and Low Orbit Ion Cannon (LOIC).  On the other hand, the snort-based Intrusion Detection System (IDS) can be used to detect such attacks that occur within the network perimeter including on the web server. Based on the research result, snort has the ability to detect various types of attack including port scanning attacks and multiple snort rules can be accurately set to protect the network from any unknown threats.

AbstractThe last decade has seen rise in technologies that allow humans to send and receive intimate touch across long distances. Drawing together platform studies, digital intimacy studies, phenomenology of touch, and ethics of technology, we argue that these new haptic communication devices require specific ethical consideration of consent. The paper describes several technologies, including Kiiroo teledildonics, the Kissenger, the Apple Watch, and Hey Bracelet, highlighting how the sense of touch is used in marketing to evoke a feeling of connection within the digital sphere. We then discuss the ambiguity of skin-to-skin touch and how it is further complicated in digital touch by remediation through platforms, companies, developers, manufacturers, cloud storage sites, the collection and use of data, research, satellites, and the internet. Lastly, we raise concerns about how consent of data collection and physical consent between users will be determined, draw on examples in virtual reality and sex-robotics, and ultimately arguing for further interdisciplinary research into this area.

When transnationally constructed art forms, such as the works of diasporic cultural productions of Arabs in the West, are made available in open-source on a digital archive, this supports the transnational flow or exchange of citizenship-enhancing ideas, skill-sets, technologies, tools, capacities, and practices. In this theoretical investigation, we explore imagined outcomes when new audiences can engage with diasporic cultural productions of Arabs. Digital archiving of ethnically diverse cultural productions can expand civility, solidarity, and common ground among people; these latter behaviors are the ideational foundations of agency-based claims of transnational citizenship. Such cultural productions help to reconfigure the questions, opportunities, and nature of political and social agency in ways that empower diaspora communities and expand their abilities to make citizenship claims in multiple societies. This is what the Internet enables despite its tendency towards parochialism in globalized pockets. Moreover, we highlight the possibilities of open-source digital archiving—with a focus on literature, poetry, biographies, and letters—for agency-based claims of citizenship and the many caveats that require further attention and consideration.

Knowledge Based

There has been an increasing emphasis on enhancing students’ practical experience acquiring from the higher education, focusing not only on the development of academic and intellectual capabilities and subject knowledge, but also on the development of skills to equip students for employability. A practical training system that allows instruments to be monitored and controlled over the Internet leaves plenty of room to be studied. This training system can easily be turned into online experiment that allows students at remote locations to control and obtain real-time measurements or experimental data (Tan & Soh, 2001). Actually, some students like to read books to gain knowledge, while others prefer to understand theories deeper through experiment (Chu, 1999; Whelan, 1997). Both of these knowledge-based and investigative types of learning styles have profound and different effects on the delivery and acceptance of engineering education.

Assembling is one of the important factors in our daily life. The aim of assembling is to obtain a particular function from the subassembly which is generated by putting some parts together. This fact shows that assembling machine parts is possibily the most appropriate example to exeute. If we assemble some machine parts, we decide the positions by their shapes, and then, make sure both the state of parts by reaction force fed back to the hand when a part touches other parts and the behavior of the subassembly. In addition, it is advisable to use both hands for assembly. In this research, we constructed a virtual work space using a force display which gives us haptic sensation returned from not only assembling operation but collaboration with both hands.
