This paper presents a novel One-shot pulse Generator Circuit, which is composed of only one differential voltage current conveyor (DVCC) as the active element. The application circuits utilizing the DVCC are introduced and implemented. Only one DVCC and two resistors and one capacitor are required to construct every circuit. Each circuit is able to provide a pulse-shaped response having changeable width via a positive-edge triggered signal. The first one is a general one-shot pulse generating circuit. The second design can reduce the recovery time after applying triggered signals. Is-Spice is the simulation software to simulate every model. To fabricate the models commercially available ICs (AD844AN) and passive elements are required. Program and experimental outputs satisfy theoretical results. © Springer Science+Business Media Singapore 2017.

Polyvinyl alcohol (PVOH) was chemically modified by crosslink copolymerization of acrylic acid (AA) and acrylamide (AM) in aqueous solution of PVOH and finally crosslinking the copolymer of AA and AM designated as PAAAM with N,N0-methylenebisacrylamide (NMBA) and PVOH with glutaraldehyde to produce a full interpenetrating network (FIPN) membrane. Accordingly, a membrane containing PVOH:PAAAM of 1:0.5 designated as FIPN500 was synthesized. Filled FIPN membranes were synthesized by in situ incorporation of highly hydrophilic aluminosilicate filler during copolymerization of the monomers in PVOH matrix to produce three filled membranes designated as FIPN502, FIPN505, and FIPN510 containing 2, 5 and 10 mass%, respectively (of total polymer) of the filler. PVOH membrane cosslinked with 2 mass% glutaraldehyde, PAAAM copolymer modified PVOH membrane i.e. FIPN500 and the three filled FIPN membranes were used for sorption and pervaporative dehydration of acetic acid. The filled IPN membranes were found to show higher flux and water selectivity than the unfilled membranes. Among the three filled membranes, FIPN510 was found to show the highest flux (6.612 kg m 2 h -1 andmu;m) and water selectivity (325.53) at 0.953 mass% water in feed. Interaction parameters, partial permeability, intrinsic membrane selectivity and concentration average diffusion coefficients for all the membranes were also evaluated. © 2011 Elsevier B.V.

Automatic extraction of time plane features is important for cardiac disease diagnosis. This paper presents a multiresolution wavelet transform based system for detection and evaluation of QRS complex, P and T waves. Selective coefficient method is based on identification of proper and optimum set of wavelet coefficients to reconstruct a wave or complex of interest from the ECG signal. The performance of the system is validated using original 12 lead ECG recording collected from the physionet PTB diagnostic database. The measured values are compared with the manually determined values and measurement accuracy is calculated. The test result shows over 99% true detection rate for R peak and base accuracy over 97%, 96%, 95%, 98% for heart rate, P wave, QRS complex and T wave respectively. © 2009 Elsevier Ltd.

Blend membranes were prepared by solution blending of sodium alginate (SA) and sodium carboxymethyl cellulose (CMC) in water with varied compositions. One of the blend membranes containing 25% SA and 75% CMC was found to show optimum flux and benzene selectivity for 19.6 wt% benzene in cyclohexane. This unfilled blend membrane designated as F0 was further filled with 2, 4, 6 and 8 wt% organophilic bentonite filler to obtained four filled membranes designated as F2, F4, F6 and F8, respectively. These five (one unfilled and four filled) membranes were characterized by various conventional methods like FTIR, XRD, DTA (for unfilled blend membranes) and SEM (for filled membranes). These membranes were used for pervaporative separation of benzene from its mixtures with cyclohexane over the concentration range of 0.5-20 wt% benzene. The filled F8 membrane showed lower flux (35.65 kg μm/m2 h) than the unfilled F0 membrane (77 kg μm/m2 h) but separation factor for benzene of the F8 membrane (212) was much higher than the F0 membrane (88.7). © 2013 Elsevier B.V.

Acrylic acid (AA) and acrylamide (AM) was free radically copolymerized with 5:1 comonomer ratios in the matrix of polyvinyl alcohol (PVOH). Full interpenetrating network polymer (FIPN) was produced by crosslinking PVOH with glutaraldehyde and the copolymer with N′N′ methylene bis acrylamide (NMBA). Three FIPN membranes containing PVOH:copolymer weight ratio of 1:25, 1:5 and 1:75 designated as FIPN25, FIPN50 and FIPN75, respectively, were synthesized. These full IPN membranes were used for pervaporative separation of tetrahydrofuran (THF)-water mixtures over the concentration range of 78-99 wt.% THF in water. Glutaraldehyde crosslinked PVOH membrane was also used for the same study for comparison. Florey-Huggin lattice model and engaged species induced clustering (ENSIC) model were used to explain sorption of permeants in the membranes. Modified solution-diffusion model was used to find diffusion coefficient, plasticization coefficient and coupling coefficients of the penetrants through the membranes. Intrinsic membrane permeability and selectivity of the membranes were also determined. For an azeotropic composition of 94.3 wt.% THF in water the thickness normalized flux and water selectivity obtained from PVOH, FIPN25, FIPN50 and FIPN75 membranes were 3.2, 2.25, 3.45 and 3.6 kg mμ/m 2 h and 15.10, 32.50, 79.34 and 70.43, respectively. © 2012 Elsevier B.V.

The efficiency of a grinding wheel and quality of surface finish of the machined component mainly depend on the type of abrasive material, abrasive grain size, bonding material, wheel grade, and wheel structure. Modern grinding wheels use various types of abrasive materials, ranging from aluminum oxide to partially stabilized zirconia, and also superabrasive materials, like CBN and diamond. Owing to diverse conflicting necessities, no distinct abrasive material can meet all the requirements of grinding applications. Every abrasive material has its own mechanical and physical properties that make it best for a particular application. Consequently, it is extremely important to select the suitable abrasive for a grinding wheel with the desired properties for enhanced surface finish and grinding performance. This paper considers a list of eight grinding wheel abrasives whose performance is evaluated based on seven criteria. Fuzzy technique for order performance by similarity to ideal solution method is applied to solve this grinding wheel abrasive material selection problem, and a complete ranking of the abrasive material alternatives is achieved. Synthetic polycrystal diamond, cubic boron nitride (CBN), and tungsten carbide, respectively, obtain the first, second and third ranks. Yttria stabilized zirconia is the worst preferred grinding wheel abrasive material. A Pareto optimality analysis also confirms this result. Copyright © 2013 Taylor and Francis Group, LLC.

In today's metalworking industry, many types of materials, ranging from high carbon steel to ceramics and diamonds, are used as cutting tools. Because of the wide range of conditions and requirements, no single cutting tool material meets all the needs of machining applications. Each tool material has its own properties and characteristics that make it best for a specific machining application. While evaluating a cutting tool material for a machining operation, the applicability is dependant on having the correct combination of its physical properties. Thus, it is extensively important to select the most appropriate cutting tool material with the desired properties for enhanced machining performance. This paper considers an exhaustive list of 19 cutting tool materials whose performance are evaluated based on ten selection criteria. The grey complex proportional assessment (COPRAS-G) method is then applied to solve this cutting tool material selection problem considering grey data in the decision matrix. Synthetic single crystal and polycrystal diamonds emerge out as the best two choices. Oil quenched tool steel (AISI O2) and powder metal tool steel (AISI A11) may also be used as the suitable cutting tool materials. Sialon and sintered reaction bonded silicon nitride are the worst chosen cutting tool materials. © 2011 Elsevier Ltd.

The medical organizations have introduced Telecare Medical Information System (TMIS) to provide a reliable facility by which a patient who is unable to go to a doctor in critical or urgent period, can communicate to a doctor through a medical server via internet from home. An authentication mechanism is needed in TMIS to hide the secret information of both parties, namely a server and a patient. Recent research includes patient’s biometric information as well as password to design a remote user authentication scheme that enhances the security level. In a single server environment, one server is responsible for providing services to all the authorized remote patients. However, the problem arises if a patient wishes to access several branch servers, he/she needs to register to the branch servers individually. In 2014, Chuang and Chen proposed an remote user authentication scheme for multi-server environment. In this paper, we have shown that in their scheme, an non-register adversary can successfully logged-in into the system as a valid patient. To resist the weaknesses, we have proposed an authentication scheme for TMIS in multi-server environment where the patients can register to a root telecare server called registration center (RC) in one time to get services from all the telecare branch servers through their registered smart card. Security analysis and comparison shows that our proposed scheme provides better security with low computational and communication cost. © 2014, Springer Science+Business Media New York.

This paper aims to select the optimal location and setting parameters of SVC (Static Var Compensator) and TCSC (Thyristor Controlled Series Compensator) controllers using PSO (Particle Swarm Optimization) to mitigate small signal oscillations in a multimachine power system. Though Power System Stabilizers (PSSs) associated with generators are mandatory requirements for damping of oscillations in the power system, its performance still gets affected by changes in network configurations, load variations, etc. Hence installations of FACTS devices have been suggested in this paper to achieve appreciable damping of system oscillations. However the performance of FACTS devices highly depends upon its parameters and suitable location in the power network. In this paper the PSO based technique is used to investigate this problem in order to improve the small signal stability. An attempt has also been made to compare the performance of the TCSC controller with SVC in mitigating the small signal stability problem. To show the validity of the proposed techniques, simulations are carried out in a multimachine system for two common contingencies, e.g., load increase and transmission line outage. The results of small signal stability analysis have been represented employing eigenvalue as well as time domain response. It has been observed that the TCSC controller is more effective than SVC even during higher loading in mitigating the small signal stability problem. © 2012 Elsevier Ltd. All rights reserved.

Activated hedgehog signaling (Hh) cascade was first found in basal cell carcinoma but with time it has been found in other major cancer types including medulloblastoma (MB), pancreatic cancer, small cell lung cancer, liver cancer, leukemia etc. Small molecule antagonists of Hh pathway were developed to block either Hh ligands or Smoothened (Smo), a transmembrane receptor that controls Gli based downstream signaling cascades of Hh pathway. Among many Smo inhibitors like naturally occurring cyclopamine or synthetic small molecule IPI-926, GDC-0449, LDE-225, GANTs etc few small molecules are in clinical trial, and one small molecule GDC-0449 has been approved by FDA. Limitation of using Smo antagonists is due to rapid mutation in Smo itself and hence the new generation Hh antogonists like HPI-1 or HPI-2 have been developed which are capable of bypassing Smo and attacking downstream effector Gli1 directly and hence the major activated Hh pathway effectors or entire Hh signaling are suppressed. In this review, we will discuss the development of different small molecule inhibitors of Hh pathway to treat cancer. © 2014 Bentham Science Publishers.
