Semantic Web Mining of Un-structured Data: Challenges and OpportunitiesCSCJournals
The management of unstructured data is acknowledged as one of the most critical unsolved problems in data management and business intelligence fields in current times. The major reason for this unresolved problem is primarily because of the actuality that the methods, systems and related tools that have established themselves so successfully converting structured information into business intelligence, simply are ineffective when we try to implement the same on unstructured information. New methods and approaches are very much necessary. It is a known realism that huge amount of information is shared by the organizations across the world over the web. It is, however, significant to observe that this information explosion across the globe has resulted in opening a lot of new avenues to create tools for data management and business intelligence primarily focusing on unstructured data. In this paper, we explore the challenges being faced by information system developers during mining of unstructured data in the context of semantic web and web mining. Opportunities in the wake of these challenges are discussed towards the end of the paper.
This document discusses the rise of big data and how the volume of data being created is growing exponentially, with 2.5 quintillion bytes created daily from various sources like sensors, social media, images, videos and purchases. It outlines how traditional databases and data analytics are struggling to handle this unstructured data, leading to the emergence of new solutions like Hadoop. It also explores how new roles like data scientists are emerging to help organizations extract value from all this big data through advanced analytics.
The document discusses privacy concerns related to big data. It notes that as individuals leave large digital trails through online activities like social media, this data is being collected and analyzed by companies. While this data collection can help with marketing, it also raises privacy issues as digital behavior can be used to infer identities even when data is anonymized. The document explores these tensions and how privacy regulations are aiming to protect individual anonymity, but this is challenging given how useful data loses anonymity.
This document summarizes the key features of the SwiftSpace modular furniture system. The system can be reconfigured quickly, in minutes rather than hours, without tools. It provides electrical, data and privacy solutions. Various workstation arrangements are shown that can be easily adapted to different room functions throughout the day, such as lectures, group work, and exams.
Simulation of Suction & Compression Process with Delayed Entry Technique Usin...AM Publications
The rapidly increasing worldwide demand for energy and the progressive depletion of fossil fuels has led to an
intensive research for alternative fuels which can be produced on a renewable basis. Hydrogen in the form of energy will almost
certainly be one of the most important energy components of the early next century. Hydrogen is a clean burning and easily
transportable fuel. Most of the pollution problems posed by fossil fuels at present would practically disappear with Hydrogen
since steam is the main product of its combustion. This Paper deals with the modeling of Suction and Compression Processes for
Hydrogen Fuelled S.I.Engine and also describes the safe and backfire free Delayed entry Technique. A four stroke,
Multicylinder, Naturally aspirated, Spark ignition engine, water cooled engine has been used to carrying out of investigations of
Suction Process. The Hydrogen is entered in the cylinder with the help of Delayed Entry Valve. This work discusses the insight
of suction process because during this process only air and Hydrogen enters in to cylinder, which after combustion provides
power. Simulation is the process of designing a model of a real system and conduction experiment with it, for the purpose of
understanding the behavior of the design. The advent of computers and the possibilities of performing numerical experiments
may provide new way of designing S.I.Engine. In fact stronger interaction between Engine Modelers, Designers and
Experimenters may results in improved engine design in the not-to-distant future. A computer Programme is developed for
analysis of suction and Compression processes. The parameter considered in computation includes engine speed, compression
ratio, ignition timing, fuel-air ratio and heat transfer. The results of computational exercise are discussed in the paper.

Performance Analysis of OFDM system using LS, MMSE and Less Complex MMSE in t...AM Publications
In this research, Channel estimation has been accomplished for OFDM framework. In wireless communication, because of a nonappearance of channel estimation a decent execution of communication doesn't accomplish. Also, it is critical for wireless communication that transmission of information at high rate and transmission with least mistake could conceivable. Such a variety of times in remote correspondence, abundance of a sign get vacillated. This variance influences the execution of wireless communication. So to beat these issues channel estimation is essential. In channel estimation pilots get joined with transmitting information, and this consolidated data goes through channel and reaches at recipient. At accepting side estimation get perform with the assistance of those pilots. OFDM have a significance in remote correspondence as OFDM gives high rate of data, additionally it gives low multipath contortion, these properties are essential to increase great execution of remote correspondence. This is motivation to choose OFDM in this study. This concentrate essentially thinks about three distinct calculations for divert estimation in OFDM framework. Likewise this study contrasts these calculations and traditional OFDM. This study utilizes comb type pilot insertion method, and this procedure is extremely valuable to diminish the impact of fast fading in wireless communication environment.
Dynamically Partitioning Big Data Using Virtual Machine MappingAM Publications
Big data refers to data that is so large that it exceeds the processing capabilities of traditional systems. Big data
can be awkward to work and the storage, processing and analysis of big data can be problematic. MapReduce is a recent
programming model that can handle big data. MapReduce achieves this by distributing the storage and processing of data
amongst a large number of computers (nodes). However, this means the time required to process a MapReduce job is
dependent on whichever node is last to complete a task. This problem is bad situation by heterogeneous environments. In
this paper a methodologyis properly to improve MapReduce execution in heterogeneous environments. It is carried out
using dynamically partitioning data during the Map phase and by using virtual machine mapping in the Reduce phase in
order to maximize resource utilization.
OFDM: Modulation Technique for Wireless CommunicationAM Publications
Orthogonal Frequency Division Multiplexing (OFDM) has become the modulation technique for many wireless
communication standards. In a wireless system, a signal transmitted into channel bounces off from various surfaces resulting
in multiple delayed versions of the transmitted signal arriving at the receiver. The multiple signals are received due to the
reflections from large objects, diffraction of electromagnetic waves around objects .This causes the received signal to be
distorted. OFDM provides tolerance to such frequency selective channels and provides high data rates. In this paper we propose to analyze the theory of OFDM, simulate the OFDM transceiver using MATLAB and perform BER analysis.

ABSTRACT:- Big data is a relative term describing a situation where the volume, velocity and variety of data exceed an organization’s storage or compute capacity for accurate and timely decision making. Big data refers to huge amount of digital information collected from multiple and different sources. With the development of application of Internet/Mobile Internet, social networks, Internet of Things, big data has become the hot topic of research across the world, at the same time; big data faces security risks and privacy protection during collecting, storing, analyzing and utilizing. Since a key point of big data is to access data from multiple and different domains security and privacy will play an important role in big data research and technology. Traditional security mechanisms, which are used to secure small scale static data, are inadequate. So the question is which security and privacy technology is adequate for efficient access to big data. This paper introduces the functions of big data, and the security threat faced by big data, then proposes the technology to solve the security threat, finally, discusses the applications of big data in information security. Main expectation from the focused challenges is that it will bring a novel focus on the big data infrastructure.
Introduction to big data – convergences.saranya270513
Big data is high-volume, high-velocity, and high-variety data that is too large for traditional databases to handle. The volume of data is growing exponentially due to more data sources like social media, sensors, and customer transactions. Data now streams in continuously in real-time rather than in batches. Data also comes in more varieties of structured and unstructured formats. Companies use big data to gain deeper insights into customers and optimize business processes like supply chains through predictive analytics.

Abstract:
Big Data concern large-volume, complex, growing data sets with multiple, autonomous sources. With the fast development of networking, data storage, and the data collection capacity, Big Data are now rapidly expanding in all science and engineering domains, including physical, biological and biomedical sciences. This paper presents a HACE theorem that characterizes the features of the Big Data revolution, and proposes a Big Data processing model, from the data mining perspective. This data-driven model involves demand-driven aggregation of information sources, mining and analysis, user interest modeling, and security and privacy considerations. We analyze the challenging issues in the data-driven model and also in the Big Data revolution.

We have entered the big data era. Organizations are capturing, storing, and analyzing data that has high volume,
velocity, and variety and comes from a variety of new sources, including social media, machines, log files, video,
text, image, RFID, and GPS. These sources have strained the capabilities of traditional relational database
management systems and spawned a host of new technologies, approaches, and platforms. The potential value of
big data analytics is great and is clearly established by a growing number of studies. The keys to success with big
data analytics include a clear business need, strong committed sponsorship, alignment between the business and
IT strategies, a fact-based decision-making culture, a strong data infrastructure, the right analytical tools, and people
skilled in the use of analytics. Because of the paradigm shift in the kinds of data being analyzed and how this data is
used, big data can be considered to be a new, fourth generation of decision support data management. Though the
business value from big data is great, especially for online companies like Google and Facebook, how it is being
used is raising significant privacy concerns.

Global Situational Awareness of A.I. and where its headedvikram sood
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.

End-to-end pipeline agility - Berlin Buzzwords 2024Lars Albertsson
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.
