In this paper, three-dimensional Green’s functions in anisotropic elastic bimaterials with imperfect interface conditions are derived based on the extended Stroh formalism and the Mindlin’s superposition method. Four different interface models are considered: perfect-bond, smooth-bond, dislocation-like, and force-like. While the first one is for a perfect interface, other three models are for imperfect ones. By introducing certain modified eigenmatrices, it is shown that the bimaterial Green’s functions for the three imperfect interface conditions have mathematically similar concise expressions as those for the perfect-bond interface. That is, the physical-domain bimaterial Green’s functions can be obtained as a sum of a homogeneous full-space Green’s function in an explicit form and a complementary part in terms of simple line-integrals over [0,π] suitable for standard numerical integration. Furthermore, the corresponding two-dimensional bimaterial Green’s functions have been also derived analytically for the three imperfect interface conditions. Based on the bimaterial Green’s functions, the effects of different interface conditions on the displacement and stress fields are discussed. It is shown that only the complementary part of the solution contributes to the difference of the displacement and stress fields due to different interface conditions. Numerical examples are given for the Green’s functions in the bimaterials made of two anisotropic half-spaces. It is observed that different interface conditions can produce substantially different results for some Green’s stress components in the vicinity of the interface, which should be of great interest to the design of interface. Finally, we remark that these bimaterial Green’s functions can be implemented into the boundary integral formulation for the analysis of layered structures where imperfect bond may exist.

The integrity advisers are the central actors of integrity management systems of the administrative organizational structure, whose main task is to promote the implementation of the integrity approach within state administration institutions. As a complementary part of this task, we can separate the tasks of corruption prevention and the improvement of organizational integrity, of which the latter being discussed in more detail in this research and presentation. Integrity advisers play a key role in the development of organizational culture among public administration bodies, such as bodies exercising administrative authority. Looking at the topic more closely, with regard to the activities of integrity advisers, it can be clearly established that one of the engines of their operation is the proper and deep communication, which is not only necessary within the public administration and inter-agency transactions, but it also means communication activities that can be interpreted in the relationship between the public and clients. Equally important is their training and other activities aimed at developing staff awareness, relationships, situation assessment and action practices, which, in addition to and in part within public service training, provide an opportunity to shape organizational culture. The presentation and the paper aims to show the role of integrity advisors in developing organizational culture and transparency in the administration based on recent research experience about online presence of integrity advisors and in-depth interview surveys.

Introduction. The article deals with the problem of the main changes expected in the framework of the digital economy are considered. Particular attention is paid to the areas of transformation the knowledge capital in these conditions. A driver of modern digital economy should be regarded as an intellectual capital that based on the combined use of the intangible assets and the information resources of the enterprises. The formation of the intellectual capital of a company is viewed from a systemic perspective and in conjunction with the formation of the knowledge capital of the enterprises. Prpose. The purpose of our article is to determine the distinctive role of corporate knowledge in the formation of the intellectual capital of the enterprise in the digital economy, substantiation of the principle of complementarity in the trajectory of modern transformations of knowledge capital of the organization within the concept of the intellectual capital. Methods. We have used a set of general and special methods in this article (they are historical and logical method, method of analysis and synthesis, grafhic constraction, scientific abstraction). Results. The article presents the author’s view on the emergence of the knowledge capital of the enterprises in the context of the prevailing economic theories, based on an analysis of the evolution of the category «knowledge». The role of knowledge capital for the intellectual capital of the enterprises and its essence in the relational (customer) capital, organisational capital and human capital of the company, firms. The carried-out analysis and synthesis of the existing approaches on studying of intellectual capital of the enterprises taking into account specifics of the knowledge capital of the company are used to support existing managerial policies for better retention practices and management of human resources, for better management practices of the enterprises. Prospects. The leading vector for the development of the intellectual capital of the enterprises in the digital economy should be the question of designing the process of cumulation, classification, measurement and transformation of knowledge capital, as well as the development of tools for translating its elements into materialized and innovative assets of the organization.

This chapter presents an algorithm for identifying complementary site of objects broken into two parts. For a given 3D scanned image of broken objects, the algorithm identifies the rough sites of the broken object, transforms the object to a suitable alignment, registers it with its complementary part which belongs to the same object, and finds the local correspondence among the fragmented parts. The presented algorithm uses multiple granularity descriptors and edge extraction to detect the exact location of multiple cleavage sites in the object. It greatly reduces the amount of information to be matched and also helps in identification of the parts; as a result it reduces the computational time in the processing. It is also applicable to all triangulated surface data even in the presence of noise.

A path planning method is presented based on non-autonomous dynamic modeling of open-loops in articulated systems. It is assumed that one part of the mechanical system is submitted to specified motions laws, while movements of the complementary part are free. Thus, motion optimization is related to free joint movements but it is achieved on the basis of the dynamic model of the whole mechanical system. This approach introduces a non-autonomous state equation of a special type in the sense that it can not only depend on the running time but also on the unknown travelling time. The cost function to be minimized involves the travelling time and the actuating inputs. Optimization is achieved by applying the Pontryagin Maximum Principle which yields a new optimality condition concerning the travelling time dependency of the stated problem. Two simulation examples are presented. The first one shows how the developed technique makes possible both the reducing and mastering the dynamic complexity of a four degrees of freedom-vertical manipulator. Set at four degrees of freedom, the second one deals with a redundant planar manipulator characterized by a mobile base that is submitted to a specified driving motion.

The global pandemic has affected all sectors and disrupted not only supply chains but also had a particular impact on the range of services provided and the whole service sector. Outsourcing is used to adapt to business environment changes. However, in the scholarly literature, outsourcing of services is analysed as a complementary part of the manufacturing process—there is a lack of research on outsourcing in service companies. This article analyses the enablers of outsourcing in all service groups. The aim of the semi-structured interview was to determine not only the enablers, their significance in each WTO (World Trade Organisation) group of services but also the use of outsourcing in the provision of core and non-core services. The results of the empirical study revealed that outsourcing is increasingly used in the service sector; however, enablers vary depending on the provision of services, the nature of the service company’s activities, and the needs they meet, public or for-profit.

The solution of the boundary value problem of anisotropic Föppl–von Kármán plates is shown to be a critical point for a suitable energy functional. Moreover, under the assumption that the minimum of the total energy exists, we prove a saddle-point property and also deduce from it the form of the boundary conditions for plates clamped on part of the boundary and loaded on the complementary part.

Trust management has been emerging as an essential complementary part to security mechanisms of P2P systems, and trustworthiness is one of the most important concepts driving decision making and establishing reliable relationships. Collusion attack is a main challenge to distributed P2P trust model. Large scaled P2P systems have typical features, such as large scaled data with rapid speed, and this paper presented an iterative and dynamic trust computation model named IDTrust (Iterative and Dynamic Trust model) according to these properties. First of all, a three-layered distributed trust communication architecture was presented in IDTrust so as to separate evidence collector and trust decision from P2P service. Then an iterative and dynamic trust computation method was presented to improve efficiency, where only latest evidences were enrolled during one iterative computation. On the basis of these, direct trust model, indirect trust model, and global trust model were presented with both explicit and implicit evidences. We consider multifactors in IDTrust model according to different malicious behaviors, such as similarity, successful transaction rate, and time decay factors. Simulations and analysis proved the rightness and efficiency of IDTrust against attacks with quick respond and sensitiveness during trust decision.
