We report the detection of H2CO (formaldehyde) around the carbon-rich AGB star, IRC+10216. We find a fractional abundance with respect to molecular hydrogen of x(H2CO) = 1.3 +1.5 −0.8 × 10 . This corresponds to a formaldehyde abundance with respect to water vapor of x(H2CO)/x(H2O) = (1.1±0.2)×10 , in line with the formaldehyde abundances found in Solar System comets, and indicates that the puta...

Consider a family of chords i n a c ircle . is obtained by representing each chord by a vertex, two vertices being connected by an edge when the corresponding chords intersect. I n t h i s paper, we describe e f f i c i en t algorithms for finding a ma3cimwn clique and a maximum independent s e t of circle graphs. the number of vertices i n the graph. Key WO&: Circle graph, transi t ive graph, ...

Many network intrusion detection systems (NIDS) rely on protocol-specific analyzers to extract the higher-level semantic context from a traffic stream. To select the correct kind of analysis, traditional systems exclusively depend on well-known port numbers. However, based on our experience, increasingly significant portions of today’s traffic are not classifiable by such a scheme. Yet for a NI...

Emails in the workplace are often intentional calls to action for its recipients. We propose to annotate these emails for what action its recipient will take. We argue that our approach of action-based annotation is more scalable and theoryagnostic than traditional speech-act-based email intent annotation, while still carrying important semantic and pragmatic information. We show that our actio...

We present a system for Emotion Analysis of Instant Messages (IM). Using Instance Based classifier we have shown that our system can outperform similar systems in the IM domain. Tagged instant messages and elaborate feature engineering can help a lot in increasing the performance of text classification of unstruc-tured, ungrammatical text. The impact of class imbalance on classification has bee...

The measurement of performance of Internet Protocol IP network can be done by Transmission Control Protocol TCP because it guarantees send data from one end of the connection actually gets to the other end and in the same order it was send, otherwise an error is reported. There are several methods to measure the performance of TCP among these methods genetic algorithms, neural network, data min...

Internet-of-Everything (IoE) has gradually been recognized as an integral part of future wireless networks. In IoE, there can be ultra-massive number smart devices various types to served, imposing multi-dimensional requirements on communication, sensing, and security. this article, we provide a tutorial overview the promising intelligent reflection communication (IRC) technologies, including r...

The Internet offers a tremendous opportunity for experiments with real-time machine translation (MT) dialogues. Interchanges may be typed, or speech recognition (SR) techniques might be used to accept spoken input. In either case, given the number of ambiguities still escaping automatic resolution, interactive disambiguation for both components seems likely to remain important in many Internet ...

A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. Now a days, bridge deck section of Box shapes are used widely. Most of the bridges constructed are of Box girders. Method of post-tensioning in the construction of bridges is very common today. Most of the bridges are ...

We study here, from both theoretical and experimental points of view, the cyclic structures, both general and primitive, of dynamical systems Dd generated by iterations of the functions Td acting, for all d ≥ 1 relatively prime to 6, on positive integers : Td : N −→ N; Td(n) = { n 2 , if n is even; 3n+d 2 , if n is odd. In the case d = 1, the properties of the system D = D1 are the subject of t...
