UV- Spectrum of Tamra Yoga showed maximum absorption at 307 nm; FT-IR analysis showed 11 peaks between the wavelengths 3356.21 - 418.34 cm-1 and ICP–OES analysis revealed Potassium as main constituent in 14376.50 ppm

Multi-objective optimization approach for cost management during product design at the conceptual phase

The effective cost management during the conceptual design phase of a product is essential to develop a product with minimum cost and desired quality. The integration of the methodologies of quality function deployment (QFD), value engineering (VE) and target costing (TC) could be applied to the continuous improvement of any product during product development. To optimize customer satisfaction and total cost of a product, a mathematical model is established in this paper. This model integrates QFD, VE and TC under multi-objective optimization frame work. A case study on domestic refrigerator is presented to show the performance of the proposed model. Goal programming is adopted to attain the goals of maximum customer satisfaction and minimum cost of the product

Application of Taguchi approach and Utility Concept in solving the Multi-objective Problem when

The traditional Taguchi method is widely used for optimizing the process parameters of a single response problem. Optimizationof a single response results the non-optimum values for remaining. But, the performance of the manufactured products isoften evaluated by several quality characteristics/responses. Under such circumstances, multi-characteristics response optimizationmay be the solution to optimize multi-responses simultaneously. In the present work, a multi-characteristics responseoptimization model based on Taguchi and Utility concept is used to optimize process parameters, such as speed, feed, depthof cut, and nose radius on multiple performance characteristics, namely, surface roughness (Ra) and material removal rate(MRR) during turning of AISI 202 austenitic stainless steel using a CVD coated cemented carbide tool. Taguchi’s L8 orthogonalarray (OA) is selected for experimental planning. The experimental result analysis showed that the combination of higherlevels of cutting speed, depth of cut, and nose radius and lower level of feed is essential to achieve simultaneous maximizationof material removal rate and minimization of surface roughness. The ANOVA and F-tests are used to analyze the results.Further, the confirmation tests are conducted and the results are found to be within the confidence interval

Tweet Scrutiny For Fast Communication Reporting

The major target of the system is develop a new earthquake detection algorithm it is used for To speed-up the detection process and  reduce false detections.But here having one problem is Absence of evidence is not evidence of absence”Why? Because traditional phase associators do not know If the missing station is broken.  If not, when the pick for that station will be made available. That is used for Detection bases ONLY on the presence of picks in a certain time-window. Assumption: If the network is reliable, all the operating stations in the surrounding of the epicenter will detect ground motion change and the picker will produce a P-wave detections with a a priori known delay. If the network is reliable, we can look only at close stations.   The number of words in a tweet message and the position of the query within a tweet. We can apply methods for sensory data detection to tweets processing

RE-GRADE MODEL FOR LABEL BASED ICON SEARCH

An easy approach must be to attach the whole routing path in each and every packet. The publication within the approach is its message overhead may be large for packets with extended routing pathways. While using the routing route to each packet, many measurement and diagnostic approaches can conduct effective management and protocol optimizations for deployed WSNs made up of a great deal unwatched sensor nodes. own path features a novel an easy-weight hash function for verification within the deduced pathways. To be able to further boost the inference capacity along with execution efficiency, own path features a fast bootstrapping formula to rebuild the very first number of pathways. To really increase the risk for iterative boosting effective and efficient, two problems have to be addressed. The hash function ought to be lightweight and efficient enough since it should be focus on resource-restricted sensor nodes. While using the routing route to each packet, many measurement and diagnostic approaches can conduct effective management and protocol optimizations for deployed WSNs made up of a great deal unwatched sensor nodes. We implement own path and evaluate its performance using traces from large-scale WSN deployments additionally to extensive simulations. Results show own path achieves much greater renovation ratios under different network settings when compared with other condition-of-the-art approaches. When compared with PathZip, own path exploits high path similarity between multiple packets for fast inference, leading to far better scalability

THE EFFECT OF BIODIESEL AND BIOETHANOL BLENDED DIESEL FUEL ON THE PERFORMANCE AND EMISSION CHARACTERISTICS OF A DIRECT INJECTION DIESEL ENGINE

History has seen fuel innovations being driven majorly by transportation needs rather than the overall need to revolutionize the energy needs of the society. Biofuels such as biodiesel and bioethanol are now receiving the impetus required for becoming a fuel source for the future. One of the ways to reduce the dependence on fossil diesel is the blending of bioethanol with conventional diesel. However, an emulsifier or a co-solvent is required to stabilize the blend. The ricebran oil biodiesel offers an alternative application as an emulsifier for diesel-ethanol blends to form diesel-biodiesel-ethanol blends. In the present study the rice bran oil biodiesel was used in different ways such as pure biodiesel, blending with diesel and diesel- ethanol blends. The performance and emission characteristics of a direct injection (DI) diesel engine when fuelled with conventional diesel fuel, pure biodiesel, a blend of diesel and biodiesel and three blends of diesel-biodiesel-ethanol were studied over the entire range of load on the engine. The experimental results showed that the highest brake thermal efficiency was observed with 30% ethanol in diesel-biodiesel-ethanol blends. The exhaust gas temperature and sound reduced with the increase of ethanol percentage in diesel-biodiesel-ethanol blends. The Carbon monoxide, smoke, exhaust gas temperature and sound reduced with the increase of ethanol percentage in diesel-biodiesel-ethanol blends. The minimum values of Carbon monoxides, smoke, exhaust gas temperature and sound intensity were observed with the blend BE30 and were respectively 41.23%, 14.5%, 0.57% and 11.53% lower than that of the diesel fuel. The Oxides of nitrogen and carbon dioxide emissions increased with the increased percentage of ethanol in diesel-biodiesel-ethanol blends. The hydrocarbon emissions increased with ethanol but lower than that of the diesel fuel by a maximum of 35.35% with 10% ethanol in diesel-biodiesel-ethanol blend. The blending of 20% biodiesel into diesel-ethanol blends allowed higher percentage (30%) of ethanol mixing with diesel, increased the brake thermal efficiency and reduced the carbon monoxide, sound, hydrocarbons and smoke than that of the diesel fuel. So the rice bran oil biodiesel can be used as an emulsifier to mix higher percentage of ethanol with fossil diesel to improve the performance and reduce the emissions of a diesel engine

Ionic mass transfer at point electrodes located at cathode support plate in an electrorefining cell in presence of rectangular turbulent promoters

Current density plays a major role in deciding the plant size, current efficiency, and energy consumption in electrorefining cells. In general, operating current density will be 40% of the limiting current density. Forced circulation of the electrolyte in the presence of promoters improves the mass transfer coefficient. In the present study, rectangular turbulence promoters are fitted at the bottom side of the cell to improve the mass transfer coefficient at the cathode support plate. The limiting current density technique is used to measure the mass transfer coefficient. The variables covered in the present study are the effects of flow rate, promoter height, and spacing among the promoters. The electrolyte consists of copper sulfate and sulphuric acid. At a regulated flow rate, the electrolyte is pumped from the recirculation tank to the cell through an intermediate overhead tank. The limiting current density increased with an increasing flow rate in the presence of promoters, and thus the overall mass transfer coefficient on the cathode support plate also improved. With an increase in the flow rate of the electrolyte from 6.67 × 10−6 to 153.33 m3/s, limiting current density increased from 356.8 to 488.8 A/m2 for spacing of 0.30 m, with a promoter height of 0.01 m. However, it is noteworthy that when the promoter height is increased from 0.01 to 0.07 m, the overall mass transfer coefficient is found to increase up to 60%, but with the further increase in the promoter height to 0.30 m the mass transfer coefficient starts to decrease. Therefore, the optimized cell parameters are established in this work. The current sustainable concept of employing rectangular turbulence promoters will bring benefits to any precious metal refining or electrowinning tank house electrolytes

ANALYTICAL STANDARDIZATION OF RAJATA BHASMA

Bhasma Kalpana is a unique part of Ayurvedic Rasa shastra. It is a method of converting metals into metallic Bhasma. Metallic Bhasmas are well known for its quick effectiveness, smaller dose and a long shelf life. However if these Bhasmas are not well prepared and analyzed they can be toxic to human body. Therefore Bhasma Pariksha is given in Ayurveda to confirm the well prepared metallic Bhasma, but in this era we need to analyze the Bhasmas on modern parameters too to make it acceptable globally. So in this study prepared Rajata (Silver) Bhasma is analyzed on various parameters i.e. Ayuvedic parameters i.e., Varitaratwa, Rekhapurnatwa, Slakshantwa and Laghutwa and some modern parameters like, pH, Particle size, Zeta Potential, X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X-ray spectroscopy, Fourier Transform Infra red Spectroscopy (FTIR), U V – Spectroscopy. Results: pH value is 5.6, UV- spectroscopy showed maximum absorption at 302nm, FT-IR of Rajata bhasma reveals the presence of C-H (alkyl), C-N (Aliphatic amine) groups at different wavelengths, Mean Particle size of Rajata bhasma is 2.7nm, Zeta Potential analysis reveals -19.3 mV, X-RD of Rajata bhasma reaveals the major peaks of HgS (Cinnabar), Ag2S (Silver Sulphide), SEM analysis of Rajata bhasma showed small crystalline particles at 5KX & 10KX magnifications, EDX analysis of Rajata bhasma confirmed the presence of elements viz., Sulphur 20.34%, Oxygen 7.43%, Silver 26.72%, Mercury 45.51% by weight

Identification of Tubercle Bacilli from Indian Patients with Pulmonary Tuberculosis

Pretreatment cultures of bacilli from Indian patients with active pulmonary tuberculosis admitted to a controlled domiciliary chemotherapy study by the Tuberculosis Chemotherapy Centre, Madras, were subjected to a series of in vitro tests designed to identify the bacilli as human or bovine tubercle bacilli, or as anonymous mycobacteria. For the purposes of comparison, pretreatment cultures from British patients with pulmonary tuberculosis were examined by the same series of identification tests. Cultures identifiable as mammalian tubercle bacilli were obtained from all the 341 Indian patients admitted to the chemotherapy study. Tests for niacin production were carried out on the cultures from 277 of these patients ; all gave positive results, indicating that the bacilli in question were Mycobacterium tuberculosis var. hominis. The culture from the Indian patients yielded results similar to those of the cultures from the British patients in all the in vitro tests except the thiacetazone-sensitivity test. In this test the Indian cultures differed from the British cultures, being on the average less sensitive and showing greater variation in sensitivity among themselves
