Abstract: Most peristaltic blood pumps in hemodialysis machines currently use open-loop control, which leads to a relatively high perturbation level of flow rate. For some reasons, the blood flow rate from the peristaltic pump can't be measured directly. In this research, two simple but effective methods including empirical formula and polynomial curve fitting are applied to describe the relationship between the blood flow rate and RPM of the pump head. Both of the two methods perform well in describing the relationship. But the modified empirical formula is preferred because of its relatively low computational complexity. Taking RPM of the pump head as an indirect feedback of the flow rate, a robust repetitive control method is applied to lower the fluctuation level of the blood flow rate. And the result exhibits a better performance when it is compared with the general repetitive control.

Keywords: Peristaltic pump, hemodialysis machine, blood flow rate, robust repetitive control.

Abstract: The flow behaviour of some high ash Indian coal-water slurry for long-distance transportation has been investigated. The non-Newtonian Bingham behaviour predicted from Rheological data obtained with -Haake Rotational RV 100 viscometer and pressure drop obtained from 50 mm diameter test loop have been taken into consideration to predict pressure drop .for flow of fine coal slurries .The Run- of- mine coal from Talcher,Odisha has been crushed,ground to make it Black Mesa type distribution..A non- dimensional parameter based on increase of volumetric concentration of solids in slurry has been incorporated in Durand-type correlation for predicting pressure drop. This modified Durand type correlation also incorporates SRC (Saskatechewan Research Council), data, for flow of low ash coal slurries showing good fit .

Abstract: In our research we took the case study of a Government housing scheme implemented by Karnataka's Rajiv Gandhi Rural Housing Corporation Limited (RGRHCL). The scheme aims at providing housing for the socially and economically backward sections of the society. This scheme chooses beneficiaries (person who gets the benefit of the scheme) that own land but are extremely poor to construct houses for themselves and provide monetary aid to them to construct houses. During the implementation of this scheme, corruption prevails at different levels. Due to this the actual needy people do not receive the required aid. To overcome this drawback Karnataka Government has introduced many automations that have substantially decreased the corruption level and at the same time has led to crores of savings. Our research focuses on these automations which vary from the use of digital signature certificate to using GPS.

Abstract: Mobile ad-hoc network is an autonomous network that consists of nodes that communicate with one another with wireless channel. Mobile accidental networks (MANETs) are unit extensively utilized in military and civilian applications. MANET is employed in varied applications, like battlefield, business applications, and remote areas. One of the common attacks in MANETs is a part attack during which a malicious node incorrectly replies for any route requests while not having active route to fastened destination and drops all the receiving packets. If these malicious nodes work together as a bunch then the potential damage can be terribly serious. This kind of attack is named cooperative part attack Mobile. In this paper, we have concentrated on analysing the performance of one of the popular routing protocols for MANET AODV with Black hole AODV. Our theme relies on AODV protocol that is improved by deploying advanced DRI table with further parity. The simulation on NS2 shows effectiveness of our projected theme. Finally we eliminate the part attack and increase network performance by reducing the packet dropping quantitative relation in network. The detection of malicious node in accidental network continues to be thought of as a difficult task. Simulation shows that AODV with our mechanism gave relatively higher performance as compared to AODV.

Abstract: Aloe barbadensis Miller (True Aloe or Aloe Vera) is a perennial, succulent plant reaching a height of 80-100 cm. It has thick, fleshy leaves with serrated margins. The two major components in an Aloe Vera leaf are aloe gel(jelly like substance) present in the inner portion of the leaf and the aloe latex(bitter exudates) present just beneath the outer skin of the leaf. Aloe Vera gel has active constituents such as acids, amino acids, lipids, polysaccharides, minerals, enzymes, vitamins, lactates, salicylates and phenolics which are responsible for antiseptic, coagulant, cell growth stimulating, pain inhibiting, scar inhibiting, anti-inflammatory and astringent properties. Aloe latex contains anthraquinones which act as laxatives. Aloe Vera has many topical uses such as relief from burns, wounds, sunburns, insect bites, frost bites, herpes outbreaks, and various skin problems and in preventing scars. Oral uses include oxygenation of blood, removal of oxidative stress, lowering cholesterol and blood sugar, treatment of digestive disorders like ulcers, IBS and crohn's disease, nourishment of body with vitamins, minerals, amino acids and glyconutrients and relieving constipation. It is also the secret to healthy and flawless skin as it is anti inflammatory and also has moisturizing and cooling effects. It treats minor infections like acne, pigmentation, dryness and redness of the skin. It also helps in promoting natural growth of new hair follicles as well as the existing ones hence strengthening hair growth.

Abstract: The most basic challenges of hydrology are the prediction and quantification of catchment surface runoff. Surface runoff information is required for watershed management purpose. It is a function of many variables including rainfall intensity and duration, soil type, soil moisture, land use, cover, and slope. In the study runoff was estimated using two models in Upper Krishna river basin, Maharashtra. NRCS-CN method and SHETRAN model was used to find runoff depth. Monthly Runoff was calculated using NRCS-CN model and daily runoff computed for each catchment using SHETRAN for the year 2012. Landsat 7 (with resolution 30 m) satellite data for the year 2012 has been used for the preparation of land use land cover (LU/LC) map. The hydrologic soil group is mapped using GIS platform. SHETRAN, requires more number of parameters to run the model while NRCS-CN method involves the use of a simple empirical formula and readily available tables and curves. Both model used Land use map and soil data as main input. Validation was done using measured runoff recorded in discharge gauge stations. Results of the study show that land use changes determined from satellite images are useful in studying the runoff response of the un-gauged basins. Study reveals that there is no significant difference between measured and estimated runoff depths. Using NRCS-CN method for each sub-catchment, statistically positive correlations were detected between observed and estimated runoff depth (0.6

Abstract: Exposure to embedded systems is very important for engineering students these days, as almost all branches of engineering make use of embedded computing systems. Exposure to the embedded systems and hands-on learning is usually late in the curriculum if present, and may fail to arouse interest in the students about the subject and related systems. Introduction of Embedded Computing system course at first year level in engineering education helps develop interest in related systems and also help students chose their elective subjects effectively later in the four year engineering course to successfully achieve their intended goals and also give them the edge required to enter the industry with confidence. This paper describes an experience with the usage of embedded development kits at second and third-year levels and proposes the introduction of such a program at first-year level.

Abstract: Suction investment casting processes of low-pressure turbine blades with high TiAl alloy were simulated by Procast software. Comparative results had shown that the surface of suction casting blade was more complete than that of gravity casting one. In gravity casting process, molten metal filled the thinnest trailing edge at last, resulting in the generation of misrun defects. Furthermore, the shrinkage porosity and crack defects of gravity casting were much more and dispersive. The internal and external quality of suction casting was much better than that of gravity casting.

Abstract: To describe the flow behaviors of semi-solid state alloy A356, two non-Newtonian constitutive equations are modeled in this paper. The CFD software PROCAST is used to simulate the process of die filling. The filling temperature is 585°C (solid fraction is 0.4). Based on the results of the simulation, it is found that the material in semi-solid state exhibits an apparently higher viscosity and thus, flows much more smoothly than the Newtonian fluid. In addition, the semi-solid metal alloy has a special die filling behavior compared with liquid filling which is of great importance in improving the quality of the final components.

Abstract: The research of micro aerial vehicles (MAVs) is a new field of low-Reynolds-number flow, which attracts much attention in the advanced aeronautical area. Micro air vehicles propelled by flapping wings are gaining interest for certain applications because flapping can provide more agility and manoeuvrability at low speeds. Flapping wings must deform in certain shapes to produce maximum lift and thrust. In the paper, we discuss an approach we used to design flapping wing Micro Air Vehicles (MAV), which replicating the flying patterns of birds. The development of MAV is complicated and it involves light weight design, power transmission design, flight controls, low Reynolds number flight, energy supply etc. The main objective of this work is to build an ornithopter with very less wing loading which can be used for surveillance purposes. The weight factor plays an important role and wing loading needs to be as low as possible. An experimental approach adopting trials and error methods was used to fabrication. Finally four wing MAV is designed for a wingspan of 28cm, total length of 175cm, weight of 14g and it involved a tail rotor for controlling the yawing movements. The prototype, then manufactured, assembled, performed several tests and achieved commendable flight.

Abstract: This paper aims to compare the empirical powers of some statistics for detecting multiple upper outliers in exponential samples under slippage alternative. In addition to that we also investigate masking effect for various degree of discordancy parameter. The results which are based on simulation study, indicate that the maximum likelihood ratio test statistic is better than the other statistics followed by Dixon type test statistics to deal with upper outliers in exponential samples. Also in case of combating masking the maximum likelihood ratio test statistic is better and the test proposed by Lalitha and Kumar (2012) precede Dixon type test.

Abstract: Most smartphones come with at least one camera, and camera is used mostly with media (photos, videos, etc.) sharing Android applications. Thus, hackers are finding devious ways to exploit the smartphone camera. Smartphones are almost always connected to the Internet. Most applications make use of the mobile data network or Wi-Fi to send and receive data, both in the foreground as well as in the background. In some cases, this sending and receiving of information helps in improving the efficacy of the application by connecting to, say, the social media accounts of the user or sending some user related information, such as location, to the application developer. This can help the developers to cater to the needs of the users in a better way and modify the application accordingly. However, as much as the Internet can be used to send and/or receive useful data, there is a very good chance of the same being exploited by malicious applications to transmit sensitive information which can be an infringement on the user's privacy. Such sensitive information can include personal photos, videos, SMS, etc. This transmission can very well happen without the user knowing about it.One attack that infringes on the user's privacy is a camera-based attack. There is a possibility that an Android Camera can be used to surreptitiously capture photos and/or videos without the user knowing about it. These captured photos and videos can be sent over mobile data networks or Wi-Fi to criminals/ hackers.Here, we attempt to implement the attack on mobile phones, and demonstrate the feasibility and effectiveness of the attack. Furthermore, we propose a defence scheme that can effectively detect these attacks and notify the user.

Abstract: The study on the performance of natural adsorbents like chitosan, saw dust and tea waste in the removal of chromium ion (Cr (VI)) from wastewater has been performed in batch mode. The effects of pH, adsorbent concentration, Cr (VI) concentration, contact time and shaking speed were studied on the removal of Cr (VI) from synthetic wastewater. A comparative study has been done on the adsorption capacities of the three adsorbents for Cr (VI) adsorption. The highest adsorption capacity of 99.257% has been observed with chitosan as adsorbent at optimized conditions. The equilibrium data for the batch adsorption of Cr (VI) onto natural adsorbents have been tested with Langmuir, Freundlich, BET and Dubinin-Radushkevich isotherm models. The mechanism of Cr (VI) sorption by chitosan gave good fits with the Langmuir model with a maximum adsorption capacity of 35.7 mg/g. It has been found that the kinetics of Cr (VI) adsorption onto chitosan can be explained well by the pseudo second order kinetic model. Desorption of Cr (VI) ions from the metal loaded chitosan was maximum at 0.1M of H2SO4 with an agitation speed of 120 rpm and a contact time of 60 minutes. A multiple response method, using the design expert software 8.0.6.1 was applied for optimization of adsorbent dosage, Cr (VI) concentration, contact time, agitation speed % adsorption and % desorption.

Abstract: Sub grade soil strength is an essential input for design of pavements and overlays. Many models are available for determination of subgrade soil strength. Subgrade soil strength in terms of elastic modulus value is used in Mechanistic-Empirical methods and CBR value is used in empirical methods of design. Both the parameters can be used for structural evaluation of flexible pavement. Determination of elastic moduli values of pavement layers by back-calculation of deflections measured using Falling Weight Deflectometer (FWD) is a widely used scientific method. However, extensive use of FWD for large scale evaluation of in-service pavements is not feasible, especially for low volume roads, unimportant roads and roads in developing and under developed countries. In the present investigation, an attempt has been made to develop relationships that can be used to estimate subgrade soil strength in terms of elastic modulus and CBR values using in-situ test results of Dynamic Cone Penetrometer (DCP). As DCP is a portable and low-cost equipment used for quick evaluation of unbound granular and subgrade soil. Comparative studies are also carried out with similar models available from the literature review.

Abstract: The seasonal cycles of migratory birds in predicting the carrying capacity of a marine ecosystem in the Kingdom of Bahrain was conducted. This study specifically determines the total number of avian migrants at varying months and annual cycles; find out significant difference in the total number of non-volant avian migrants at different annual cycles; and predict the carrying capacity (M) of the marine ecosystem using a logistic model. Results showed that the total number of avian migrants is high during the month of December in 2013 (642), and low in January 2011 (516). Similarly, the total number is high in cycle 3 (2013) with a total of 2,720 non-volant avian migrants while low in cycle 1 (2011) with 2,242. Statistical analysis using ANOVA revealed significant difference in the number of avian migrants at varying annual cycles. Avian migrants preferred the marine ecosystem as their temporary habitat during their annual cycles which provides various resources. The carrying capacity (M) of the identified marine ecosystem can be predicted using a logistic model. Assuming that the population growth rate of avian migrants is low (r = 0.4), and M = 1000, results depicted that the fraction of unused carrying capacity can still support the growing population. This is evidenced by the 45% unused fraction of the carrying capacity during the terminal cycle in 2013. Results further predict that the future carrying capacity will be reduced. Hence, the annual cycles of avian migrants predicts the carrying capacity of the identified marine ecosystem using a logistic model.

Abstract: Energy is the most essential element of socio-economic development and nation's economic growth. Renewable energy sources can play an immense role to fulfill this need of energy. These sources will not only enhance independency of energy but also helps in many ways such as mitigation of climate change, swift development of rural areas, improved health status and will be the best way to move towards sustainable development. Renewable energy sources, especially solar and wind, Biomass energy, are likely to play a significant role in providing reliable and sustainable electricity to consumers. Renewable Energy (RE) sources form a minuscule portion of India's overall Energy consumption today, with increasing agricultural and industrial activities in the country; the demand for energy is also increasing. Many developing countries are increasingly making commitments to promote low carbon economy by adopting sustainable energy technologies. In this regard, different policies could be applied to reducing carbon emissions, such as enhancing renewable energy deployment and encouraging technological innovations. Diffusion of Renewable Energy Technologies (RETs) is governed by the status of the technology in terms of efficiency and techno-economical feasibility. This paper presents the current energy scenario and an approach to apply diffusion modeling technique to review policies supporting Renewable energy technology deployment and use diffusion parameters to provide inputs for designing future programmes. The status of renewable energy is explored in Indian context. The state wise status, different challenges, issues, barriers, solar and wind power development and policies are discussed in detail the wind and solar power are selected for detailed analysis. The results show how present trends and future forecasts of electricity-generating technologies change the electricity generation in the country.
