    Online Community Learning: Why Does (Language) Learning Without Classroom Interest Students of All Disciplines? a Case Study

    Full text link
    This case study explores the language learners' growing interest to express their shared interest in online-course-providing platforms. This study also inquires into the language learners' new forum called “online community” and its great influence on smart way teaching-learning process and classroom dynamics, technology enabled lifelong self study mode of learning, subject knowledge, learning centred curriculum, experience centred approach to the learning process, course material and soft/life skills delivered along the course as a value added package. This paper examines the way MOOCs have opened the gate way of learning to all sections of society free of cost with specific language skills focus – writing that interests students from all disciplines. This study suggests that the rising generation shows a growing, academic interest in online collaboration on the basis of any subject specific shared interest and this collective interest also addresses the concern about personal experiences with emotive foundation that will not have space in online teaching learning process

    Predicting the Attacks in IoT Devices using DP Algorithm

    The fundamental goal of this study is to predict cyber-attacks before they occur and to protect the network. Most existing attack detection algorithms cannot identify zero day attacks because they lack previously known data patterns to predict the threat, which is one of the biggest issues in the existing approaches. This research work offers a novel prediction method based on Gaussian regression that identifies cyber-attacks utilizing a unique dual data pattern categorization technique with no false positives. To improve the accuracy of the prediction and to reduce the prediction time consumption, this study introduces a dual prediction technique one locally – at the fog level where non-parametric input data is dealt with two functions namely quadratic & reliability function to ease the prediction and the other universally – cloud level where result of skill mechanism is carried out. Even if the local prediction misses an attack, the universal prediction sniffs it and protects the IoT devices and the data. A detailed comparison regarding accuracy and packet drop is carried out by simulating flooding attacks using on varying numbers of dummy nodes and the proposed system found to outscore the existing methods convincingly

    Aggressive research as gigabit network has led to dramatic improvements in network transmission speeds. One result of these improvements has been to put pressure on router technology to keep peace. This paper describes a router nearly completed. This is more than fast enough to keep up with the latest transmission technology. This router has a back place speed of 50 gigabit and can forward tens of millions packet.Scheduling algorithm can be implemented on CVAR applications but in this research scheduling is implemented on CBR applications and the performance on WLAN network is enclosed by delivering different traffic load. QOS parameters [5] will be considered as the performance metrics on this study. The comparative study of various algorithms can show the best scheduling algorithm in WLAN with CBR applications.ATM was the focus of action research and significant investment in the early to mid 1990’s. This paper discuss several visions for ATM prevalent at the time and analyses how ATM evolved during this period this paper also consider the amplifications of this history for current connection oriented technologies such as optical transport network and MPLS

    ATM is the new generation of computer and communication networks that are being deployed throughout the telecommunication industry as well as in campus black bones. OPNET is a CAD tools which is specialized in communication protocols and networks. We examine its performance and its effect on the traffic pattern in an ATM network. In this paper we also report the studies of simulation efficiency and network performance of simulated network using firewall

    Evaluation of MPLS Framework Congestion Control for Planning and Optimization in ATM Networks

    Recent Advances in MPLS have led to development of real-time applications. Many routing protocols have been specifically designed for these applications where real-time guarantee is an essential design issue. Real-time MPLS is an existing area of research. The common objective is trying to provide timeless guarantee for resource constrained MPLS. MPLS is emerging as a flexible technology that can transport voice,. IPV4 , IPV6 layer 2 services and even PDH and SDH/SONET circuit over a single packet infrastructure in a new attempt to solve the old problem of new network convergence. MPLS traffic emerging QOS support and fast restoration capabilities can be used to provide each service with strict service level arguments in a cost efficient way several standardization and industry organization are contributing to this goal. Keywords: Congestion Control, MPLS

    A Study on Problems Faced by Female Child Labor in Unorganized Sector of Palladam Taluk in Tirupur District

    Child labor in India is to be found in almost every sector of the informal economy. Despite India´s fast economic growth since the 1990s, many challenges remain for youth at risk, particularly the girl child. The Indian Girl Child who faces gender discrimination on various levels. Due to her lower status in the society, a girl child laborer is even more deprived. Child labor is still a prevalent issue in India. Gender is a crucial determinant of whether a child engages in labour. While child labour is an infringement of the rights of all children boys and girls alike girls often start working at an earlier age than boys, Girls also tend to do more work in the home than boys. Hence, this study focused on what are the problems faced by female child labor and their socio- economic conditions in Palldam taluk of Tirupur District of Tamilnadu

    The ATM UBR, GFR over ABR service categories have been designed for data. However several studies have responded poor TCP performance over satellite ATM resources. We first discuss the various design options available for TCP end systems, IP-ATM switches for long latency connections. We discuss the buffer management policies generated and rate services and the virtual stores destination options in ATM. We present comparison of ATM service categories for TCP transport over satellite links. Keywords: Video Teleconferencing, Adaptive Schedulin

    QOS Reliability and Improvement for Congestion Probability Routing in ATM Networks

    The other primitives for switch management and control are borrowed heavily from the specified protocol. They include priority for switch configuration port and switch management VP management and permanent measurement. The protocol was implemented and integrated with the OPNET platform. Without going into specifies of the protocol we describe its design principles and show how it has affected in the protocol. Traditional connection switches include an embedded processor that implements both the switch control and network signaling. The objective of CAC is to keep the network load moderate to achieve a performance objective associated with QOS. Cell loss ratio a key QOS parameter in ATM networks is essential for proper network resources dimensioning, congestion control , bandwidth allocation and routing.
