Trusted Network Selection using SAW and TOPSIS Algorithms for Heterogeneous Wireless Networks

Seamless continuity is the main goal in fourth generation Wireless networks (FGWNs), to achieve this "HANDOVER" technique is used, when a mobile terminal(MT) is in overlapping area for service continuity, Handover mechanism are mainly used. In Heterogeneous wireless networks main challenge is continual connection among the different networks like WiFi, WiMax, WLAN, WPAN etc. In this paper, Vertical handover decision schemes are compared and Multi Attribute Decision Making (MADM) is used to choose the best network from the available Visitor networks (VTs) for the continuous connection by the mobile terminal. In our work we mainly concentrated to the handover decision phase and to reduce the processing delay in the period of handover. MADM algorithms SAW and TOPSIS where compared to reduce the processing delay by using NS2 to evaluate the parameters for processing delay.Comment: arXiv admin note: substantial text overlap with arXiv:1106.240

Active Vibration Control of Structures using an Impedance Matching Control Technique

Active vibration control of structures has gained a lot of interest in recent years. This paper presents an active vibration control methodology of a structure using piezoelectric actuators. The proposed methodology is useful in practical applications where the system to be controlled is difficult to model due to the presence of complex boundary conditions. The impedance matching control technique uses a power flow approach wherein the controller is designed such that the power flow into the structure is minimized. The system transfer function is obtained from the experimental collocated actuator/sensor pair data using Eigen Realisation Algorithm (ERA). The controller is designed for the system transfer function according to impedance matching theory. The above approach is targeted towards the vibration control of wind tunnel stings, which suffer from flow-induced vibration. A wind tunnel sting model is designed and fabricated for this study. The real time implementation of the impedance matching controller has been carried out using dSPACE® Digital Signal Processor (DSP) card. The results are encouraging and demonstrate the feasibility of applying this technique in the wind tunne

Significance of transvaginal sonographic assessment of cervical length before induction of labour

Background: The traditional method of predicting whether an induced labor will result in successful vaginal delivery is based on pre-induction favourability of cervix as assessed by bishop score. However, this method is limited by subjectivity and reproducibility and though done in all the patients prior to induction of labour, several studies have demonstrated poor correlation between Bishop score and outcome of labor. Currently assessment of cervical status by sonographically at term in induction of labor is most accurate and highly reproducible compared to Bishop score.Methods: This study was carried out in a tertiary care teaching institute in Karnataka. 180 pregnant women at or beyond 37weeks who were planned for induction, Bishop score assessment of cervix and cervical assessment by ultrasound such as cervical length (CL) was done one day prior to induction. Induction was with 0.5mg PGE2gel. Maximum 3 induction were carried out over a period of 24hrs. Primary outcome of the study was the onset of active labor.Results: Amongst 160 pregnant women who were induced (20 women were excluded has they underwent LSCS for some other reasons during latent phase) cervical length by sonography <2cm were 14 none had failed induction. Amongst 180 pregnant women who were induced cervical length <2cm in 14 all had Bishop score >4.Conclusions: Transvaginal sonographic measurement of cervical length was evaluated in predicting response to induction. CL <2cm was associated with greater incidence of successful labor induction. These results show the CL has significant role in predicting outcome of labor

Light Dependent Morpho-Physiological Changes and Yield Response of Hybrid Napier Cultivars under Rainfed System

For small dairy farmers in the tropics, open land for fodder cultivation is often limited because of the predominance of tree crops and paddies. Probably because of this limitation, to offset fodder supply for the livestock, growing fodder crops under tree crops such as coconut is a widely prevalent practice in the tropics. However, successful establishment and growth of most fodder crops especially high yielding types such as hybrid napier under shade depends on the amount of light available and the consequent morpho-physiological responses of the crops

Malic enzyme : Its purification and characterization from Mucor circinelloides and occurrence in other oleaginous fungi

Malic enzyme was purified 43-fold from Mucor circinelloides. The enzyme was dependent on Mg2+ or Mn2+ for activity, was not active with Dmalate and had a pH optimum at 7.8. The apparent Km values for malate and NADP+ were 488 ΜM and 41 Μm respectively. The Mr of the native enzyme was 160 kDa. Five metabolic analogues of malate: oxaloacetate, tartronic acid, 1-methylenecyclopropane trans-2,3-dicarboxyIic acid, malonic acid and glutaric acid, were found to inhibit malic enzyme activity at 10 mM. Four oleaginous fungi, Mucor circinelloides, Mortierella alpina, Mortierella elongata and Pythium ultimum, were also examined, all possessed a soluble malic enzyme, two also possessed a microsomal malic enzyme

Framework for progressive segmentation of chest radiograph for efficient diagnosis of inert regions

Segmentation is one of the most essential steps required to identify the inert object in the chest x-ray. A review with the existing segmentation techniques towards chest x-ray as well as other vital organs was performed. The main objective was to find whether existing system offers accuracy at the cost of recursive and complex operations. The proposed system contributes to introduce a framework that can offer a good balance between computational performance and segmentation performance. Given an input of chest x-ray, the system offers progressive search for similar image on the basis of similarity score with queried image. Region-based shape descriptor is applied for extracting the feature exclusively for identifying the lung region from the thoracic region followed by contour adjustment. The final segmentation outcome shows accurate identification followed by segmentation of apical and costophrenic region of lung. Comparative analysis proved that proposed system offers better segmentation performance in contrast to existing system
