Information processing theory

of the important aspect in deciding the reliability of any system and Cyber – Physical systems cannot be ruled out from this important issue. In this paper we investigate the security issues in CPS, enforcing sensor network theory information flow based theory and control theory in CPS which are the three primary approaches to system security policies and mechanisms. In brief we will categorize attacks based on these three primary approaches and also discuss some of the mitigations to inflate the growth

Abstract— This paper presents the design of an optimized Compressive Sensing (CS) based image compression technique for data transmission over mobile wireless noisy channel. The proposed technique is more robust to channel noise. It uses individual measurement driven coding scheme, which facilitates simpler encoder design. The shift of computational burden from encoder to decoder is more suitable for mobile devices applications where computational power and battery life are limited. This paper also

codes as well as convolutional codes. Simply put, a turbo code is formed from the parallel concatenation of two codes separated by an interleaver. The turbo principle is a general way of processing data in receivers so that no information is wasted. This technique corresponds to an iterative exchange of soft information between different blocks in a communications receiver in order to improve overall system performance. It has opened up a new way of thinking in the construction of communication algorithms

The major benefit of using a GA is that it does not require gradient information which is generally computationally expensive. Several authors worked on developing genetic algorithms and improving the genetic operators as well as fine tuning parameters [29,30,31]. However, they can be computationally expensive for more complex

In our 21st century reality, new media and technology has transformed, with little resistance, almost every aspect of daily life; redefining our reality. From plasma screens to monitors to smartphones, we are constantly face to face with the black screens of our devices, or ‘black mirrors’. Canadian professor, Marshall Mcluhan described media as “artificial extensions of sensory existence,”; meaning, each media technology functions as a prosthetic, working in conjunction with our minds and bodies

As I look back at my personal history with communication technology I remember using many forms of social media to communicate with my friends and family. Back in the day when I was in junior high I remember using MySpace, Skype, and phone calls. Today on the other hand I mainly use Facebook, Instagram, and Snapchat. There are many reasons why I use these sites but I use some sites more frequently than others it just depends on the person I want to communicate with. My social media usage varies

What is Data Science? A. Data Science is the extraction of learning from information. We can also say that data science is the study or collection of information from various sources and turn it into valuable data for business and IT fields. According to IBM estimation, what is the percent of the data in the world today that has been created in the past two years? A. An entire 90 percent of all the data on the world has been produced throughout the most recent two years. What is the value of petabytestorage

As with the improvement of cameras that produce high quality videos and images, storage needed to store the videos is became a big issue especially for the film makers that have huge video files to store. Thus we need a mechanism that make the videos compact so that they efficiently store on the hard drives and other storage devices. Here comes the compression techniques that makes it possible to remove the redundancy from bit stream of video files so they take less place to be stored. Transmission

Answer a) To prove that the BUBBLESORT actually sorts, we need to show that the A’ and A contains the same elements. Since the only operation that we perform during bubblesort is swapping of elements within the array, it is pretty straightforward to conclude that the A’ and A contains same elements. Answer b) Loop Invariant: At the start of each iteration (j) of the for loop (lines 2-4), A[j] contains the smallest element in the range (j … A.length). Also, the elements in the range (j… A.length)

This technique increases the constellation size so that each of the point in the original basic constellation can be mapped into several equivalent points in the expanded constellation. Since substituting a point in the basic constellation for a new point in the larger constellation is equivalent to injecting a tone of the appropriate frequency and phase in the multicarrier signal, therefore, this technique is called tone injection. The extra degrees of freedom, which is generated as each symbol
