We present a new approach for disassembling executables with self-modifying code. Self-modifying code is very common in malware. Conventional static or dynamic approaches cannot handle self-modifying code very well. We combine static and dynamic analysis to fight against self-modifying code with the multiple-path exploration technique. The evaluation results indicate that our approach works well in disassembling executables with self-modifying code with high precision and code coverage compared with the state-of-art disassembler.

The static and dynamic analysis of slender systems, which in this paper comprise lines and flexible links of manipulators, requires large deformations to be taken into consideration. This paper presents a modification of the rigid finite element method which enables modeling of such systems to include bending, torsional and longitudinal flexibility. In the formulation used, the elements into which the link is divided have seven DOFs. These describe the position of a chosen point, the extension of the element, and its orientation by means of the Euler angles Z[Formula: see text]Y[Formula: see text]X[Formula: see text]. Elements are connected by means of geometrical constraint equations. A compact algorithm for formulating and integrating the equations of motion is given. Models and programs are verified by comparing the results to those obtained by analytical solution and those from the finite element method. Finally, they are used to solve a benchmark problem encountered in nonlinear dynamic analysis of multibody systems.

The effectiveness of state regulation of the market of educational services in Ukraine involves several stages. Each of them regulates a certain component of the effectiveness of state regulation. By government regulation we mean an alternative mechanism that compensates for market inefficiency. The basis for government intervention are market gaps, errors. The market and the state are not without flaws: the choice between the market and the state is only a choice between different degrees and types of imperfection. However, in a real mixed economy, state regulation is a typical phenomenon, so there are grounds for its analysis and evaluation. There are the following types of efficiency of state regulation: economic, social, adaptive. Economic efficiency presupposes the conformity of the obtained result to the set socio-economic goal and the methods by which it is achieved. Social efficiency implies a social, or social, succession of political and economic measures taken by the state, as the influence of most instruments of public policy is twofold and contradictory. The adaptive efficiency of state regulation is subject to both static and dynamic analysis. Static analysis considers adaptive efficiency in the narrow sense as a response to developments in the economy, as well as change. Dynamic analysis covers a broader aspect: the subject is the active activities of the state aimed at preventing problems that arise. The effectiveness of the state in the market of educational services depends not only on the increase in budget allocations, especially since public revenues and the public sector always have relative growth limits. The highest form of state regulation is state programming, as it involves the integrated use with a global goal of all elements of state regulation of the economy: political, economic rules and contracts. An example of state programming is the structural reforms that are being carried out in Ukraine today. An important component of structural reforms is education reform. Public administration is carried out through the process of interaction between objects and subjects of public administration. The subjects of public administration are the executive authorities, and the object is the system they govern, in those who are subject to the will of the subjects and their decision.

In the industrial world the interest in Precision Positioning Systems is exponentially increasing in relation to the rapid growth of Ultra High Precision (UHP) machining. A greater attention is given to traditional techniques and developing of innovative solutions. This paper intends to present a review of the actual state of art in precision positioning system based on flexure hinge related to industrial machines, showing a comparison between different techniques.

The advent of android operating system introduced tools to keep track of users’ information activities and prevent information leakage which bridged the trust between application developers and consumers. Literature shows that several phenomena had been developed to prevent malicious applications from stealing personal sensitive information from smart phones but there is still the need for efficient solutions. This study proposes a conceptual approach for the development of a contentAnalyzer for information leakage detection and prevention on android-based devices. The concept will help to minimize false positives that will in turn lead to increase in code coverage towards detecting the maximum number of data leaks. The proposed concept combines both static and dynamic analysis, and if implemented will improve checking through the codes in the file activities and vulnerabilities that could be a problem. Keywords: Android, ContentAnalyzer, Static Analysis, Dynamic Analysis, Information leakage, Information leakage detection, Information leakage Prevention.

Vision is the science that informs us about the biological and evolutionary algorithms that our eyes, opticnerves and brains have chosen over time to see. This article is an attempt to solve the problem of colour to grey conversion, by borrowing ideas from vision science. We introduce an algorithm that measures contrast along the opponent colour directions and use the results to combine a three dimensional colour space into a grey. The results indicate that the proposed algorithm competes with the state of art algorithms.

How should a liberal democracy respond to hate groups and others that oppose the ideal of free and equal citizenship? The democratic state faces the hard choice of either protecting the rights of hate groups and allowing their views to spread, or banning their views and violating citizens' rights to freedoms of expression, association, and religion. Avoiding the familiar yet problematic responses to these issues, this book proposes a new approach called value democracy. The theory of value democracy argues that the state should protect the right to express illiberal beliefs, but the state should also engage in democratic persuasion when it speaks through its various expressive capacities: publicly criticizing, and giving reasons to reject, hate-based or other discriminatory viewpoints. Distinguishing between two kinds of state action—expressive and coercive—the book contends that public criticism of viewpoints advocating discrimination based on race, gender, or sexual orientation should be pursued through the state's expressive capacities as speaker, educator, and spender. When the state uses its expressive capacities to promote the values of free and equal citizenship, it engages in democratic persuasion. By using democratic persuasion, the state can both respect rights and counter hateful or discriminatory viewpoints. The book extends this analysis from freedom of expression to the freedoms of religion and association, and shows that value democracy can uphold the protection of these freedoms while promoting equality for all citizens.

Li–S batteries (LBSs) have received extensive attention owing to their remarkable theoretical capacity (1672 mA h g–1) and high energy density (2600 Wh kg–1), far beyond the state of art...
