  • VRIC - Modelling simple human-robot collaborative manufacturing tasks in interactive virtual environments
    Proceedings of the 2016 Virtual Reality International Conference on - VRIC '16, 2016
    Co-Authors: Elias Matsas, George-christopher Vosniakos, Dimitrios Batras
    Abstract:

    This paper presents in brief a novel interactive Virtual Environment (VE) that simulates in real-time collaborative manufacturing tasks between a human and an industrial robotic manipulator, working in close proximity, while sharing their workspaces. The use case scenario is highly collaborative and incorporates a wide variety of interaction tasks, such as: collaborative handling, manipulation, removal, placement and laying of carbon fabric composite parts. A Kinect sensor and a Head Mounted Display (Oculus Rift) are employed as 3D User Interfaces for interaction, immersion and skeletal tracking of the user motion. In this paper, particular emphasis is given to the various interaction techniques used to facilitate implementation of virtual Human-Robot Collaboration (HRC). The collaborative tasks are principally executed with contactless, natural and direct interaction. In addition, two novel interaction metaphors were developed. The real fabric laying task and the Backing Film removal task are reproduced in the VE with the implementation of the "follow-my-hand" technique; the user has to follow with his hand a virtual hand-like index (guide) that moves along a predefined pattern. Preliminary findings concerning the effectiveness of HRC modelling tasks are positive, and are briefly discussed.

  • QUANTITATIVE ANALYSIS OF BIO-MEDICAL SAMPLES OF VERY SMALL QUANTITIES BY THE STANDARD-FREE METHOD
    International Journal of PIXE, 2011
    Co-Authors: K. Sera, S. Futatsugawa, S. Hatakeyama, Y. Saitoh, K. Matsuda
    Abstract:

    A standard-free method developed by ourselves has been applied to bio-medical samples of less than 1 mg or less than 1 μl, to which an ordinary internal standard method can not be accurately applied. As the result, correct values of potassium concentration in NIST-Bovine liver samples of nearly 0.5 mg were obtained. Furthermore, the standard-free method has been applied to small quantity of serum and whole-blood samples, and satisfactory results were obtained. For samples which easily peel off from a Backing Film, such as serum and whole blood, a carbon tape with an adhesive agent was also used as a Backing Film, and it is found that this method is also applicable. Moreover, the standard-free method was confirmed to be effective for a case where a specially designed x-ray absorber is used.

  • PIXE QUANTITATIVE ANALYSIS AT NMCC
    International Journal of PIXE, 2011
    Co-Authors: S. Futatsugawa, S. Hatakeyama, Y. Saitoh, K. Sera
    Abstract:

    The facilities of the NMCC have been opened to other scientists and researchers of universities and institutes in Japan for their academic contribution since 1993. A lot of study subjects of PIXE are accepted every year. We tried to confirm that elemental concentrations in a sample were determined exactly at the quantitative analysis using PIXE facilities at NMCC. The known quantity of a standard liquid sample was dropped and dried on a polycarbonate membrane filter that was used ordinarily as a Backing Film for an aerosol sample collection. The determined values of elements in targets agree with the values evaluated from the added quantities of the standard liquid samples.

  • ANALYSIS OF LIQUID WASTE USING PIXE
    International Journal of PIXE, 2011
    Co-Authors: S. Futatsugawa, S. Hatakeyama, Y. Saitoh, M. Matsushita, H. Inoue, K. Sera
    Abstract:

    Non-radioactive liquid waste generated in the Kaya Memorial Takizawa Laboratory was analyzed using the PIXE system established at the Nishina Memorial Cyclotron Center. Samples of the liquid waste were collected at several stages of the non-radioactive liquid waste purifying process. A simple sample preparation method for liquid sample was adopted. Liquid sample was dropped and dried directly on the Backing Film after adding the internal standard element, which produced appropriate targets to be analyzed by PIXE. Sodium, silicon, sulfur, chlorine, potassium, calcium, iron and so on in the liquid sample were detected. The PIXE method used in this study showed outstanding properties for analyzing the liquid sample.

  • PIXE ANALYSIS OF HEAD BONE
    International Journal of PIXE, 2011
    Co-Authors: S. Futatsugawa, K. Sera, S. Hatakeyama, Y. Saitou, A. Adachi
    Abstract:

    An unknown bone was analyzed by PIXE at the Nishina Memorial Cyclotron Center. The head bone had a normal area, a rotted area and the green colored area on its surface. An extremely small amount of powder was cut from each area. Each powder sample was fixed on a Backing Film with a small amount of collodion liquid. The concentrations of sodium and chlorine are relatively high compared with that of other elements in all powder samples. The concentrations of copper and zinc in the colored area are higher than that in the other areas. The analytical results by PIXE agreed with other investigated results. We describe one of the applications of PIXE to archaeology field.

  • QUANTITATIVE ANALYSIS OF POWDER SAMPLE (SOIL AND CITY ASH)
    International Journal of PIXE, 2011
    Co-Authors: S. Futatsugawa, S. Hatakeyama, Y. Saitou, K. Sera
    Abstract:

    Quantitative analysis of powder sample, soil, ash and so on, which consists of rich heavy metal elements that are not decomposed easily with acid or alkali was attempted. Usually, powder sample was ground with an agate mortar, mixed with binding material cellulose and pelletized for quantitative PIXE analysis. However, the resulting pellet target is thick. Accordingly, when heavy elements are included in sample, it gives effect on PIXE spectrum. Namely, matrix effect arises on it. So firstly, a fixed quantity of molybdenum was added into sample and mixed as standard material in order to determine the concentration of the most typical element, iron included in sample. Then the mixed powder were pelletized and analyzed to determine the concentration of iron. Next, original powder sample was pushed on a Backing Film to make thin target, and the thin target was analyzed as internal standard of determined iron by ordinary PIXE analysis method. In the result, concentrations of major elements of powder sample were determined quantitatively.

  • Effect of Backing Films on the transdermal delivery of cyclobenzaprine patch
    Asian Journal of Pharmaceutical Sciences, 2016
    Co-Authors: Siji Lv, Peng Quan, Liang Fang
    Abstract:

    Abstract The aim of this study was to investigate the effect of Backing Films on transdermal delivery of cyclobenzaprine patch. Different Backing Films were chosen to prepare the cyclobenzaprine transdermal patch. The cumulative amount of cyclobenzaprine released from different patches was evaluated in vitro. To investigate the interaction between cyclobenzaprine and Backing Films, the partitioning experiments and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy were performed. The cumulative amount of cyclobenzaprine released from the patch with Cotran™ 9700 as Backing Film was less than that of other patches with different Backing Films. Furthermore, the cumulative amount of cyclobenzaprine released from the patch with Cotran™ 9700 as Backing Film decreased significantly after 7 d storage at room condition. The partitioning experiments indicated a strong adsorption of cyclobenzaprine onto the Cotran™ 9700, which could explain the decrease of cumulative amount of cyclobenzaprine released from the patch with Cotran™ 9700 as Backing Film. According to the ATR-FTIR results, there was no interaction between Cotran™ 9700 and cyclobenzaprine. The effect of Backing Films on the release behavior of cyclobenzaprine transdermal patch was attributed to the adsorption of cyclobenzaprine onto the Cotran™ 9700.

  • Drug in adhesive patch of palonosetron: Effect of pressure sensitive adhesive on drug skin permeation and in vitro-in vivo correlation.
    International Journal of Pharmaceutics, 2016
    Co-Authors: Peng Quan, Liang Fang
    Abstract:

    Abstract Palonosetron (PAL) is recommended for the prevention of chemotherapy-induced nausea and vomiting. The aim of this study was to develop a long-acting PAL transdermal patch to improve patient compliance. We were particularly concerned about the effect of pressure sensitive adhesives (PSAs) on PAL skin permeability. Formulation factors including PSAs, Backing Films and drug loadings were investigated in the in vitro skin permeation study using rabbit skin. Fourier transform infrared spectrometer study and thermal analysis were conducted to investigate the drug-PSA interaction and thermodynamic activity of PSAs, respectively. The results indicated that high drug skin permeation amount was obtained in PSA DURO-TAK®87-2516, which had low interaction potential with PAL and high thermodynamic activity. The optimized patch was composed of PAL of 8 %, DURO-TAK®87-2516 as PSA, CoTran™ 9700 as Backing Film and Scotchpak™ 9744 as release liner. The in vitro skin permeation amount of the optimized patch was 734.0 ± 55.8 μg/cm2 during 3-day administration. The absolute bioavailability of the optimized patch was 43 % in rabbit and a good in vitro-in vivo correlation coefficient was obtained (R2 = 0.989). These results indicated the feasibility of PAL transdermal patch in the prevention of chemotherapy-induced nausea and vomiting.
