Integrating Multiple Feature Descriptors for Computed Tomography Image Retrieval

Integrating multiple feature descriptors has recently shown to give excellent results for image retrieval. In this paper, we integrate multiple feature descriptors for computed tomography (CT) image retrieval, whose descriptors include the principal components descriptor, scale invariant feature transform descriptor and roberts gradient descriptor. First, we describe the retrieving image based on principal components descriptor, which is a technology of reducing the dimensions and extracting principal component. Second, we extract the scale invariant feature transform descriptor based on scale invariant feature transform algorithm. Third, the roberts gradient descriptor is obtained by roberts operator. Finally, we integrate principal components descriptor, scale invariant feature transform descriptor and roberts gradient descriptor into a retrieval vector to represent the CT image. Experimental results based on a subset of EXACT09-CT, named CASE23 and TCIA-CT show that our approach significantly outperforms the methods of the related works.

Implementation of FAST using Map-Reduce

The process of finding interesting patterns and knowledge from huge amount of data is known as Data Mining. Association rule mining is One of the most important techniques in this field is association rule mining. Association rule mining is a process which is meant to discover frequent patterns, correlations, associations, or causal structures from datasets. Feature selection is the process of selecting a subset of relevant features from large amount of data. Feature selection involves identifying a subset of the most useful features that reduces the size of original dataset. A feature selection algorithm may be evaluated from both the efficiency and effectiveness points of view. Efficiency is based on the time required to find a subset of features and the effectiveness is related to the quality of the subset of features. Based on these criteria, a fast clustering-based feature selection algorithm, FAST, is used.
AN EXPERIMENTAL STACK ATTACKS DETECTION AND RECOVERY FRAMEWORK USING AGENTS, CHECKPOINTS AND ROLLBACK

Stack based attacks are on the increase. This work generally studied stack-based vulnerabilities and attacks and focused on attacks which   employ the modification of return addresses used by control stacks. A control stack keeps track of the point in which a function returns control to after its execution. We proposed a framework that mitigates control stack attacks which utilizes kernel-controlled agent, checkpoints and rollback mechanisms. In the framework once a function is called the same return address (RA) is pushed to the control stack and also passed to the kernel-controlled agent. When a function call terminates the RA in the control stack is popped and passed to the kernel protected agent for comparison and if there is any disparity in the values of the RAs then there is an attack. In such cases the kernel protected agent directs execution of the process to stack at the latest checkpoint. The framework was implemented using Java Netbeans 7.2.1. Experimental results of the framework indicated successful detection of attacks and rollbacks in case of the attacks. Rollback indicated recovery from the attacks.

Small weight code words arising from the incidence of points and hyperplanes in PG($n,q$)

Let $$C_{n-1}(n,q)$$ be the code arising from the incidence of points and hyperplanes in the Desarguesian projective space $$\text {PG}(n,q)$$. Recently, Polverino and Zullo (J Comb Theory Ser A 158:1–11, 2018) proved that within this code, all non-zero code words of weight at most $$2q^{n-1}$$ are scalar multiples of either the incidence vector of one hyperplane, or the difference of the incidence vectors of two distinct hyperplanes. We prove that all code words of weight at most $$\big (4q-{\mathcal {O}} (\sqrt{q})\big )q^{n-2}$$ are linear combinations of incidence vectors of hyperplanes through a common $$(n-3)$$-space. This extends previous results for large values of q.
A Gesture Recognition Algorithm Based on Threedimensional Projection and Direction Chain Code

In this paper, the accelerometer of intelligent terminal is used for gesture recognition. Most of the current motion recognition algorithms in this field have great restrictions on the standardization of motion, and the recognition rate for slightly substandard motion is greatly reduced. Aiming at the existing "$3" algorithm, this paper proposes to project the 3D motion data to the 2D plane for trajectory pattern recognition, and uses the angle and radius to identify the curved area. This method can make up for the people greatly. Physiological habits lead to difficulty in the recognition of gestures, which can greatly improve the recognition accuracy when the movement is not standardized.
Project-Based Learning as a Tool for the Formation and Development of the Entrepreneurial Skills of Students

In modern conditions, one of the university functions is to train specialists who have advanced entrepreneurial skills, are competitive in the labor market and are ready for self-realization. The purpose of this research is to highlight the basic entrepreneurial skills of students and to determine the role of project-based learning in their formation. On our research we have used a combination of statistical analysis and questionnaires. The questionnaire consisted of 16 entrepreneurial skills, including technical, managerial, entrepreneurial and personal skills. To assess the responses of students a 3-point Likert Scale was used. The study involved 140 students from 2 universities of Omsk. All the participants were full-time students of the Faculty of Economics aged 21 to 23 years. The study revealed that the level of entrepreneurial skills of students after the project activity based on the business game “Business Consultant” is 12% higher than that of the control group. The indicator of 13 out of 16 assessed skills increased by 8% ± 4%. The exception was the skills of “communication”, “use of information and communication technologies” and “search and discovery of new business opportunities”, which decreased by 3%. Project-based learning helped the students to learn how to evaluate project risks and make decisions.The research can affect the quality of the basic entrepreneurial skills formation among students. The introduction of project-based learning in education will strengthen the position of the university in the market of education by quickly adapting to external changes, as well as improve the competitiveness of graduates.
A New Single-Display Intelligent Adaptive Interface for Controlling a Group of UAVs

The increasing use of unmanned aerial vehicles (UAVs) or drones in different civil and military operations has attracted attention of many researchers and science communities. One of the most notable challenges in this field is supervising and controlling a group or a team of UAVs by a single user. Thereupon, we proposed a new intelligent adaptive interface (IAI) to overcome to this challenge. Our IAI not only is empowered by comprehensive IAI architecture but also has some notable features like: presenting single-display user interface for controlling UAV team, leveraging user cognitive model to deliver right information at the right time, supporting the user by system behavior explanation, guiding and helping the user to choose right decisions. Finally, we examined the IAI with contributing eleven volunteers and in three different scenarios. Obtained results have shown the power of the proposed IAI to reduce workload and to increase user's situation awareness level and as a result to promote mission completion percentage.
Economics of Using Blockchain in the System of Labor Relations

The article considers the prospecting opportunities of using blockchain technology in the system of labor relations from the point of economics. The Transaction Cost Economics has been adopted as a conceptual basis for the argumentation since it deals with the category of “transaction costs” as a mandatory attribute of any economic relations with the exception of ideal socialist relations, where these are minimal. The objective of the article is as follows: based on the use of Transaction Cost Economics assumptions, to show the possibilities and prospects for using the blockchain in the system of labor relations as a transaction chain, which eliminates fraud, theft, breach of the rights, opportunism, i.e. minimizes transaction costs. In addition, the article researches into the need of updating the classical ideas introduced by Oliver E. Williamson on classes of regulatory structures that guarantee execution of labor relations due to the fact that the wide-scope blockchain implementation could prospectively reduce transaction costs so that these can be accompanied by a new form of regulatory structures, which the author proposes to refer to as a “smart contract”. The authors describe the justifications and examples of possible directions for the blockchain technology use to formalize specific aspects of labor relations subject to reduction in transaction costs. The article considers the possibilities, prospects, and grounds lacking in the possibilities of using blockchain technology in the labor relations system.
A new variational approach to deblurring low-resolution images

This paper proposes a new variational model for deblurring low-resolution images, a.k.a. single image nonparametric blind super-resolution. In specific, a type of new adaptive heavy-tailed image priors are presented incorporating both the model discriminativeness and effectiveness of salient edge pursuit for accurate and reliable blur kernel estimation. With the assistance of appropriate non-blind super-resolution approaches, nonparametric blind super-resolution can be cast as a regularized functional minimization problem. An efficient numerical algorithm is derived by harnessing the alternating direction method of multipliers as well as the conjugate gradient method, with which alternatingly iterative estimations for kernel and image are finally implemented in a multi-scale manner. Numerous experiments are conducted along with comparisons made among the proposed approach and two recent state-of-the-art ones, demonstrating that the proposed approach is able to better deal with low-resolution images which are blurred by various possible kernels, e.g., Gaussianshaped kernels of varying sizes, ellipse-shaped kernels of varying orientations, curvilinear kernels of varying trajectories.

Python for Gaming

It is only appropriate that we have a chapter where we discuss creating video games in Python – after all, it is that very interest that got me started programming all those years ago when I was a kid. Things have progressed a lot since then; at the time, PC games were text-based with the only images consisting of really poor quality graphics or, worse, made out of ASCII characters.

Observing the quantum Cheshire cat with a nondestructive weak measuring device

Observing counterintuitive quantum phenomena have provided physical perspectives on quantum mechanics as well as important evidence of its validity. One of such phenomena, namely the quantum Cheshire cat effect, illustrates the situation that the physical property is disembodied from its physical carrier. Here, we experimentally demonstrate the quantum Cheshire cat effect with a nondestructive weak measuring device. A pre- and post-selected photonic quantum system is subject to a weak nondestructive measuring device to probe where the photon and its polarization property can be found. Intriguingly, a quantum pointer after the weak quantum measurement indicates that the polarization can be found at the path the photon did not take.

Privacy Management in Social Network Data Publishing with Community Structure

Due to the background knowledge of the community structure, there are privacy issues with respect to published anonymous social network data. We analyzed the privacy leakage of the k-anonymity model and proposed a privacy protection method with community structure information. We implemented the proposed method by combining k-anonymous and random perturbation techniques. We used three real datasets to evaluate our privacy-preserving method. Experimental results show that our method has the same level of privacy protection as the k-anonymity model, but retains more community structure information.

Solving a hypothetical chess problem: a comparative analysis of computational methods and human reasoning

Computational modeling has enabled researchers to simulate tasks which are very often impossible in practice, such as deciphering the working of the human mind, and chess is used by many cognitive scientists as an investigative tool in studies on intelligence, behavioral patterns and cognitive development and rehabilitation. Computer analysis of databases with millions of chess games allows players’ cognitive development to be predicted and their behavioral patterns to be investigated. However, computers are not yet able to solve chess problems in which human intelligence analyzes and evaluates abstractly without the need for many concrete calculations. The aim of this article is to describe and simulate a chess problem situation proposed by the British mathematician Sir Roger Penrose and thus provide an opportunity for a comparative discussion by society of human and artificial intelligence. To this end, a specialist chess computer program, Fritz 12, was used to simulate possible moves for the proposed problem. The program calculated the variations and reached a different result from that an amateur chess player would reach after analyzing the problem for only a short time. New simulation paradigms are needed to understand how abstract human thinking works.
User Experience in Enterprise Applications

User experience is a term often used when developing any kind of web interface. Such an interface could be for a web site or web application. Implementing user experience essentially requires getting the right balance between the end goals of the business, technical restraints, and preferences of end users. User experience involves much more than just reducing the amount of clicks a user takes to achieve a goal. A lot of factors are considered in getting it right.
