Torsion of Truncated Hollow Spherical Elastic Body
234-240Views:116This paper deals with the torsion of a body of rotation whose shape is a truncated hollow sphere. The material of the truncated hollow sphere is isotropic, homogeneous and linearly elastic. To solve the torsion problem, the theory of torsion of shafts of varying circular cross section is used, which is introduced by Michell and Föppl. Analytical solution is given for the shearing stresses and displacements. A numerical example illustrates the application of the presented solution. The results of the presented numerical example can be used as a benchmark problem to verify the accuracy of the results computed by finite element simulations.

An Analytical Solution for Static Problems of Cantilever Curved Beams with Variable Cross Sections
226-233Views:120This paper gives an analytical method to obtain the deformation of a cantilever curved beam. The curved beam considered has circular centre line and the thickness of the cross section in radial direction depends on the circumferential coordinate. The kinematics of the Euler-Bernoulli beam model is used to formulate of governing equations. The curved homogeneous and isotropic elastic beam is fixed at the one of the end cross section and on the other end cross section is subjected to concentrated forces and a couple. A numerical example illustrates the applications of the derived formulae.

Macroeconomic Analysis of Expenditures on Education as Human Capital Investments
520-530Views:124The importance of actions on adaptation to economic change associated with the knowledge-based economy has continuously grown both regional and national level. Individuals' flexibly adjust and the knowledge acquired in all forms of education is very important factors in the evolving knowledge-based economies. We examine the fiscal and private expenditures on education among OECD countries between 2005 and 2013, and we analyse the development of education expenditures with particular attention to Hungary.

Issues of Regional Social Innovation
602-616Views:227Social innovation is not determined as a uniform definition, after a literature review can be defined as follows: social innovation is an innovative and new way of improving community well-being [2]. Social innovation can be defined and measured at micro-, mezo- and macro level similar to technical and economic innovation and plays a key role in the competitiveness. Because of imbalances arising from different levels of economic development, catching-up demand of peripheral settlements have appeared. In addition to the so-called technical innovations, the solution of social problems can be achieved by social tools, methods and new organizations. In catching-up process the local, community level construed innovative ideas and the activities of social innovation play a significant role. The expansion of the innovative areas results in different innovation processes and they can be considered as complementary processes. The social and technical innovation are closely interacting. If there is achange in the economic sphere, social change can occur. This study examines the role of local communities in social innovation at regional level and summarizes the clarifying questions of implementation. Social innovation as a new tool is able to answer daily challenges. The innovative solutions of municipalities, which means new collaborations, result sustainable, flexible and open leadership at regional level. This study will examine the role of governments (or their institutions) in the implementation and generating of social innovation, the tasks of regional innovators and social solutions and models of certain municipalities in Hungary and the European Union.

Automation Capabilities for the Logistics Service of Jobshop Production System
210-221Views:396One of the most important subsystems of manufacturing is the logistics system for transporting materials between technological phase. It is integrated depending on the production structure. The special feature of highly flexible workshop system production is that the material handling system is typically separate and the movement needs occur independently of each other, so the flexibility of the material handling system is required to achieve the expected production goal. In practice, therefore, the organization and execution of material handling is to a considerable extent dependent on the human factor. The purpose of this research is to explore the potential for automation of material handling activities in this particular production environment.
