Fault Tolerant, Energy Saving Method for Reliable Information Propagation in Sensor Network
Get PDFAbstract -The reliability of wireless sensor networks (WSN) is affected by faults that may occur due to various reasons such as malfunctioning hardware, software glitches, dislocation, or environmental hazards, e.g. fire or flood. Due to inherent nature of these networks a sensor node may fail and hence the route may also fail. A WSN that is not prepared to deal with such situations may suffer a reduction in overall lifetime, or lead to hazardous consequences in critical application contexts. One of the major fault recovery techniques is the exploitation of redundancy, which is often a default condition in WSNs. Another major approach is the involvement of base stations or other resourceful nodes to maintain operations after failures. In this paper we proposed a fault tolerant method for fast, robust and guaranteed prorogation in sensor networks. The proposed multi path routing approach offer better bandwidth utilization, energy saving and guaranteed delivery of information. This approach also includes error reporting features. Before sending an event source node check the remaining Energy level and highest Data rate among all its gradients and select the path on the basis of route score which consider above factors

Get PDFCONSTRUCTION AND PERCEPTUAL EVALUATION OF A 3D HEAD MODEL
Get PDFAbstract This paper presents a method to construct a compact 3D head model capable of synthesizing realistic face expressions with subtle details such as wrinkles and muscle folds. The model is assessed by Psychologists using the certified FACS coding method. Such a compact and accurate model offers a large market potential not only in Computer Graphics industries but also in low-bandwidth applications e.g. tele-conferencing, and provides a valuable novel tool for Perceptual Studies. Method and Implementation The method used to construct the 3D head model in this work is inspired from the 2D Active Appearance Model described in Besides, a synthesized face looks more authentic if not only it appears like a human, but also moves like a human. Therefore, it is very important to accurately model the dynamics of the facial expressions. Not many researches have achieved this task so far in 3D animation, which is mostly due to the limitations of their data capture equipments. In this research, we use a fast 3D video camera (48fps) to capture our training data, which allows to model a fine temporal dynamic of the face movements. Finally, we combine the method described above with FACS coding to further improve the precision of our head model. FACS is a certified method used in Psychology to study facial movements Results Our training data consists of short video sequences of Action Units (about 60 frames each). After building a joint PCA model of shape and texture, we obtain a set of Eigenvectors which represent the different modes of variations of the facial changes. Conclusion We have successfully built a 3D head model capable of synthesizing realistic-looking face expressions, reproducing accurate skin folds and expression dynamics. We plan to use this model to study and model facial idiosyncrasies
MONITORING INTRINSIC STRESS INDUCED IN THE CdSe THIN FILMS DURING DEPOSITION BY DOUBLE EXPOSURE HOLOGRAPHIC INTERFEROMETRIC TECHNIQUE
Get PDFThe double exposure holographic interferometry (DEHI) technique is used to study the intrinsic stress induced in the CdSe thin film. Cadmium selenide (CdSe) thin films have been deposited onto stainless steel and fluorine doped tin oxide (FTO) coated glass substrates by electrodeposition technique. For deposition Cadmium Sulphate (CdSO 4 ) and Selenium dioxide (SeO 2 ) are used as precursors. The structural and optical properties of the as deposited films have been studied using X-ray diffraction (XRD), Optical absorption respectively. The stress of the CdSe thin films was carried out by Double Exposure Holographic Interferometric Technique (DEHI)
Modeling the nanoscale linear response of superconducting thin films measured by a scanning probe microwave microscope
Get PDFA localized and strong RF magnetic field, created by a magnetic write head, is used to examine the linear electrodynamic properties of a Nb superconducting film. The complex reflection coefficient of the write head held in close proximity to the films is measured as a function of sample temperature. A model combining a magnetic circuit (magnetic write head inductively coupled to the sample) and transmission line (microwave circuit) is given to interpret the linear response measurement. Additionally, this reflection linear response measurement can be used to determine the temperature dependence of the magnetic penetration depth on a variety of superconductors.

EFFECT OF GLUCOSE ON PHB PRODUCTION USING Alcaligenes eutrophus DSM 545 AND TISTR 1095
Get PDFAbstract Poly-β-hydroxybutyrate (PHB) is biodegradable plastics have received increased attention due to its properties that resemble those of petroleum-based plastics such as polyethylene. PHB could be accumulated within bacterial cells varying glucose concentration in the present study. The concentrations of 5, 10, 15 and 20 g L -1 glucose were employed as a single carbon source for the PHB production which compared between Alcaligenes eutrophus DSM 545 and A. eutrophus TISTR 1095. In shake flask culture, the maximum PHB concentrations were 9.437 g L glucose. In addition, the production yield of PHB from A. eutrophus DSM 545 decreased against the glucose concentration increased from 15 to 20 g L -1 . As a result, the initial concentration of glucose beyond bacterial growth inhibition was appropriately found at 10 g L -1 . Further work would go for scale up of PHB production using A. eutrophus DSM 545

Experimental characterization of the effects of geometric parameters on evaporative pumping
Get PDFa b s t r a c t This study is interested in determining the experimental relation between the suction pressure and evaporation rate from the upper surface of a flat, thin porous membrane, which naturally draws water from a reservoir, and its microchannel feeding system. The effects of three main design parameters of a water delivery system on the evaporation rate of the membrane are considered: (i) the diameter of the microchannels irrigating the membrane, (ii) the length of the irrigating microchannels, and (iii) the surface area of the membrane. Additionally, we also evaluated the effect of the pumping height (i.e., the vertical distance between the membrane and the main reservoir) on the evaporation rates for the three design parameters. While the maximum evaporation rate from the membrane is a function of the membrane's properties (e.g., permeability and porosity), as well as the ambient conditions (e.g., temperature, pressure and humidity), this study focused on determining the geometric parameters of closed water-feeding microchannels that properly hydrate a porous membrane while not impeding evaporation. Results indicated that the evaporation rate was mostly unaffected by the channel dimensions considered. Moreover, evaporation rates increased with increasing surface area (between 20.3 cm 2 and 176.7 cm 2 ) but at a decreasing rate of return. Finally, the suction pressures achieved were inversely related to hydrodynamic pressure drop and were unaffected by the membrane diameter
Random-start controlled ovarian stimulation for emergency fertility preservation in a patient with myelodysplastic syndrome: a case report
Get PDFAbstract This study reports a case of a gonadotropin-releasing hormone agonist trigger in a young female with myelodysplastic syndrome (MDS) who underwent fertility preservation using random-start controlled ovarian stimulation. This method involves the stimulation of the ovary regardless of a patient's menstrual-cycle phase. A review of the related literature is also provided. A 17-year-old patient was diagnosed with MDS and required initiation of peripheral blood stem cell transplantation within a maximum of 3 weeks and was in the luteal phase of the menstrual cycle when the possibility of attempting preservation of fertility was presented to her. She opted for a random-start controlled ovarian stimulation with gonadotropins. With successful hemorrhagic prophylaxis, 17 oocytes were retrieved including 10 mature and 7 immature oocytes. Of the immature oocytes, 3 were successfully matured in vitro and a vitrification protocol was used to freeze the 13 mature oocytes
