We present a new approach to the integration of input devices into virtual environment software systems. Our approach employs a so-called Mapper module as an intermediate between input device drivers and virtual environment application. Major advantages of our approach are full device-independence, including the easy integration of new input devices and emulation of missing device capabilities,...

Mounting empirical evidence suggests that the observed extreme prices within a trading period can provide valuable information about the volatility of the process within that period. In this paper we define a class of stochastic volatility models that uses opening and closing prices along with the minimum and maximum prices within a trading period to infer the dynamics underlying the volatility...

We study the solution of the nonlinear BK evolution equation with the recently calculated running coupling corrections [1, 2]. Performing a numerical solution we confirm the earlier result of [3] (obtained by exploring several possible scales for the running coupling) that the high energy evolution with the running coupling leads to a universal scaling behavior for the dipole-nucleus scattering...

Background Corticosteroids are active agents, which are especially applicated orally in the dermatological emergency medicine. Due to German anaphylaxis guidelines patients emergency kit must contain a corticosteroid with a Prednisolone-equivalent of at least 100 mg. Due to different reasons, a liquid corticosteroid is to be recommended. At the present time, there is no comparable liquid remedy...

background: although stabilization ponds and lagoons are suitable treatment processes due to simplicity of operation and low per capital costs, the effluents of these systems have too high of a total suspended solids concentration to be discharged into receiving waters. this problem is mainly caused by algae. in this study, an electro-coagulation reactor was examined to re­move algae from the f...

Background: The motions of body and tumor in some regions such as chest during radiotherapy treatments are one of the major concerns protecting normal tissues against high doses. By using real-time radiotherapy technique, it is possible to increase the accuracy of delivered dose to the tumor region by means of tracing markers on the body of patients.Objective: This study evaluates the accuracy ...
