Predicting acute hypotensive episode (AHE) in patients in emergency rooms and in intensive care units (ICU) is a difficult challenge. As it is well accepted that physiological compensatory adaptations to circulatory shock involve blood flow redistribution and increase in sympathetic stimulation, we recently investigated if galvanic skin response (GSR) or electro-dermal activity (EDA), a measure of sympathetic stimulation, could give information about the impending danger of acute hypotensive episode or circulatory collapse (Subramanya and Mudol, 2012). In this current study, a low-cost wearable device was developed and tested to help progress towards a system for predicting blood pressure (BP) and cardiovascular dynamics. In a pilot study, we examined hypotheses about the relation between GSR values and four BP indexes (systolic BP, diastolic BP, mean arterial pressure and pulse pressure) in apparently healthy human volunteers before and immediately after treadmill exercise. All four BP indexes had significant relationship with GSR, with pulse pressure possibly the strongest predictor of variations in the GSR and vice-versa. This paper opens up opportunities for future investigations to evaluate the utility of continuous monitoring of GSR to forecast imminent cardiovascular collapse, AHE and shock, and could have far-reaching implications for ICU, trauma and critical care management.

We tested the hypothesis that maternal body mass index (BMI) determines fetal cardiac sympathetic activity. Heart rate variability (HRV) parameters of fetal are measured for obese & non-obese mother prior to delivery with Doppler ultrasound method. We studied 64 maternal abdominal Doppler ultrasound signals. From these, we identify 41 subjects of whose body mass index (BMI) ranging from 20 to 37. The R-R interval variability which shows the variation between consecutive heart beats, change over time was eventually adopted to calculate for time-domain, frequency domain and non linear analysis. Based on frequency analysis, the ranges of the LF and HF domains were defined as 0.04-0.15 and 0.15-0.4 Hz, respectively. We defined low frequency/high frequency (LF/HF) ratio as a index of sympathetic activity. The value of LF/HF ratio [Nonparametric Fast Fourier Transform (FFT) Based method] in normal pregnancy group displayed clearly decreasing trend with body mass index (BMI) y = - 0.013x + 0.965; R2 = 0.040 (one-way ANOVA: P <; 0.0001). The value of LF/HF ratio [Parametric Autoregressive (AR) Based] in normal pregnancy group displayed clearly decreasing trend with body mass index (BMI) y = - 0.011x + 0.8555; R2 = 0.051 (one-way ANOVA: P <; 0.0001). In consultation with gynecologists and child specialist it has been verified that the new born babies have more neurological problems following deliveries from obese mothers compared with deliveries from non-obese mothers.

A centralized digital controller design methodology is proposed for a two-input DC-DC converter. An hankel-norm based interaction analysis is developed to quantify the interaction of the controlling input and outputs of the proposed two-input dc-dc converter. The proposed converter is capable of feeding power to the common load either individually drawing from any one source or simultaneously drawing from both the sources. The load division on the two-input source is demonstrated through a two-loop control strategy. A digital current controller ensures load division in the input sources while the bus voltage regulation is achieved through a single-loop voltage-mode controller. A 24 V, 60 Watt converter performance is analyzed and compared with the experimental observations.

Cloud computing is an upcoming trend in the field of computer science in recent years. In cloud, computing resources are provided as service in the form of virtual machine to its clients across the globe based on demand. Huge demand for cloud resources results in overutilization of servers whenever there is a heavy load. It is necessary to distribute the load across the servers in cloud by taking into consideration of allocating the right amount of resources dynamically based on the load to improve the performance of applications running in virtual machines. In this paper we present an algorithm which dynamically allocate resources based on the need and distribute the load across the servers. We conducted the experiment on Xen Cloud Platform. We use response time as a metric. The experiments conducted shows that the proposed algorithm improves the performance of applications running in virtual machines by using the feature scaling and migration.

In this paper, a novel technique for the placement of phasor measurement units (PMUs) for complete and incomplete observability of a system using a search technique has been presented. It follows a graph theoretic approach. It is a two stage algorithm where first the network is reduced to eliminate radial zero injection buses, followed by the placement process. The algorithm proposed is a flexible one and can be used on systems both, with and without existing PMUs. The optimal placement set, out of the solution sets obtained, is selected depending on the geographical or communication based constraint on the nodes present in the system. The proposed technique has been tested using IEEE 14, 30 and 57 bus systems. The methodology has also been implemented on the Southern Grid (SR) of the Indian Power System.

In this paper an iterative learning controller (ILC) is designed based on the identified model of a single-link flexible manipulator (SLFM). As the system is nonlinear and time-varying so to meet the demands of the control system design, an adaptive nonlinear autoregressive with exogenous input (NARX) model is identified using the input/output experimental data. Tuning of the ILC controller is carried out using least square method. Simulation results demonstrate the potential of the NARX model based ILC controller for precise rotation tracking of a single-link flexible manipulator with suppressing link vibration.

Influx of sewage into surface water results in nutrient enrichment and consequently leads to algal bloom and voluminous organic sludge production in urban areas as in case of Bangalore. The lack of utilities of algae and resulting sludge has lead to anoxia and GHG emissions. Environmental friendly ways of sludge and algal biomass utilities as well as disposal are scant. Testing for biofuel and thermal properties can be beneficial to meet the energy requirement to run treatment plants that might have better fuel value to increase the net energy gain in the system. As the volume of algal biomass and quantity of sludge has increased over the past few years, sustainable means of biomass and sludge utilization needs to be devised for beneficial purposes, to keep the surface waters clean and regulate the biomass productivity of such systems. Therefore the biomass and sludge characterization becomes imperative for any further utilities. In the present study the indigenous suspended algae and the algal bioreactor sludge were characterized for the different functionalities and presence of bio-chemicals (carbohydrates, proteins and lipids) through Infrared Analysis (ATR-FTIR). The total lipids and fatty acid methyl esters (FAME) composition were studied. The heat values and thermal decomposition pattern were analyzed by [Thermogravimetry (TGA)/Differential Thermal Analysis (DT) and Differential Scanning Calorimetry (DSC)]. The algae were found to have a better total lipid content of >34 % compared to 22% in case of wastewater sludge with quality FAME for better biofuel properties. However there were higher number of FAME in wastewater sludge (>30) where C16 and C18 members dominated. Algal biomass showed higher calorific value of 17.96 MJkg-1 compared to 10.33 MJkg-1 of wastewater sludge.

Bilateral filters are widely used in computer vision and digital imaging applications such as denoising, video abstraction, demosaicing, optical-flow estimation etc. to name a few. Its smoothing and edge preserving characteristics suites perfectly for image and video processing applications, yet its high computational complexity makes real-time hardware implementation a challenging task. This paper provides an efficient Field Programmable Gate Array (FPGA) based implementation of an edge preserving fast bilateral filter on a hardware software co-design environment of a most recent algorithm preserving the boundaries, spikes and canyons in presence of noise. Further, the four stage parallel pipelined architecture greatly improves the speed of operation. Moreover, our separable kernel implementation of the filtering hardware increases the speed of execution by almost five times than the traditional convolution filtering, while utilizing less hardware resource.

This study was undertaken to model the tomato seed germination. Tomato seeds were subjected to electrostatic field treatments. It was found that its germination was sensitive to electrostatic field applied. The voltage gradient of 2 kV/mm for 20 second duration was found best with 100% germination in comparison with 92% germination for untreated. The relationship between seed germination and voltage gradient along with time of operation was developed using statistical approach.
