In this paper a robotic assistive device is presented, aimed at assisting physically impaired individuals when rising from a sitting to a standing position. The robotic device is designed as a three degrees of freedom (3-DOF) mechanism supporting the subject under the buttocks. The device is driven by an electrohydraulic servosystem capable of operating in multiple control modes. It is instrume...

In a Ciphertext-Policy Attribute-Based Encryption (CP-ABE) system, decryption privileges are defined over attributes that could be shared by multiple users. If some of the users leak their decryption privileges to the public or to some third party, say for profit gain, a conventional CP-ABE has no tracing mechanism for finding these malicious users out. There are two levels of traceability for ...

Industry in Ukraine is among the world’s most energy intensive. Energy was plentiful and cheap in Soviet times and little effort was made to conserve it. Rising energy prices have had a major impact on profits and production, which also creates a tremendous market potential for energy efficient products and services. Yet Ukrainian industry has not implemented significant energy efficiency measu...

The neoclassical theory of investment implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of investment), and earn higher expected stock returns than losers. The investment model succeeds in cap...

The relationship between the quality of finishing works, costs, market value, and profit, is presented and explained for residential buildings. The results show that the higher quality of finishing works increases profit for investors. As the maximum market price is limited, there is a limit when the investment in finishing work is no longer cost-effective as, after increase in costs, the marke...

This paper presents our approach for exploring the design space of input devices for three-dimensional graphics applications. We use an extended input device taxonomy as an inspiring source for generating permutations of sensors to suggest sensor configurations for new input devices. The taxonomy uses the integrated and separated degrees of freedom of an input device as a major classification c...
