With widespread use of Internet and the emergence of information aggregation on a large scale, a quality text summarization is essential to effectively condense the information. Automatic summarization systems condense the documents by extracting the most relevant facts. Summarization is commonly classified into two types, extractive and abstractive. Summarization by abstraction needs understanding of the original text and then generating the summary which is semantically related. Abstractive summarization requires the understanding of complex natural language processing tasks. There are many methods adopted for abstractive summarization. Ontology is one among the approach used for getting abstractive summary for a specific domain. In this paper, we discuss about various works carried out using ontology for abstractive text summarization.

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located several hundred meters from the ATLAS interaction point and shielded by concrete and rock, will host a suite of experiments to probe standard model (SM) processes and search for physics beyond the standard model (BSM). In this report, we review the status of the civil engineering plans and the experiments to explore the diverse physics signals that can be uniquely probed in the forward region. FPF experiments will be sensitive to a broad range of BSM physics through searches for new particle scattering or decay signatures and deviations from SM expectations in high statistics analyses with TeV neutrinos in this low-background environment. High statistics neutrino detection will also provide valuable data for fundamental topics in perturbative and non-perturbative QCD and in weak interactions. Experiments at the FPF will enable synergies between forward particle production at the LHC and astroparticle physics to be exploited. We report here on these physics topics, on infrastructure, detector, and simulation studies, and on future directions to realize the FPF's physics potential.

This paper describes use of ecommerce for easy crawling of information on an ecommerce website. As ecommerce has become an essential part in people's day-to-day activities of this modernized world. Searching & surfing data for ecommerce activity becomes tedious as lot many options & websites for single entity of ecommerce is presented before user. Internet is a huge set of database were many irrelevant data of no choice to particular task of user exist. In this paper we have designed a basic ontology of ecommerce along with its superclass & subclass as well as its siblings. This crawler design named ECOMMTOLOGY is an Ontology based Ecommerce application. Hence, we have classified ecommerce into hierarchy of business-to-business and business-to-consumer modules. The Ecommerce based ontology specifies each product details by searching, storing and retrieving user log details.

This work reports a test structure to decide on the correctness of cache performance in chip multiprocessors (CMPs). The design targets the private L1 cache existing in Tiled CMPs architecture. It is developed around the cellular automata (CA) structure proposed by von Neumann in 1950's. The theory of 3-neighborhood null-boundary CA is developed to record the inconsistent behavior of each of the processors L1 caches in CMPs. The special class of single length cycle attractor cellular automata accepts the (March) read/write status of cache word/line and evaluates the decision on the defective/inaccurate functioning of a cache module. This overcomes the inability of the classical design to identify defective behavior of CMPs cache. The test design further enables identification of the region of defective cache module in the CMPs that can help designers for defect diagnosis at design phase.

This study examines the performance of two axisymmetric nozzles which were designed to produce uniform, parallel flow with nominal Mach numbers of 4 and 8. A free-piston-driven shock tube was used to supply the nozzle with high-temperature, high-pressure test gas. The inviscid design procedure treated the nozzle expansion in two stages. Close to the nozzle throat, the nozzle wall was specified as conical and the gas flow was treated as a quasi-one-dimensional chemically-reacting flow. At the end of the conical expansion, the gas was assumed to be calorically perfect and a contoured wall was designed (using Method-of-Characteristics) to convert the source flow into a uniform and parallel flow at the end of the nozzle. Performance was assessed by measuring Pitot pressures across the exit plane of the nozzles and, over the range of operating conditions examined, the nozzles produced satisfactory test flows. However, there were flow disturbances in the Mach 8 nozzle flow that persisted for significant times after flow initiation.
