In this study, a series of organometallic hybrid polymers were synthesized through the complexation of cobalt metal ions with bisterpyridine derivatives bearing substituted 3,4-propylenedioxythiophene. The prepared polymers exhibited specific color changes from orange to dark green based on the metal-to-ligand charge transfer transitions. Cyclic voltammograms of the polymers showed a reversible redox wave according to the redox reaction of the cobalt metal ions. In addition, the electrochromic devices containing the polymer film cast on an indium-tin-oxide electrode exhibited good electrochromic properties, with reversible and stable spectral transitions of the cobalt-bisterpyridine complexes.

Background: The chemical characterization of metallic alloys and oxides is conventionally carried out by wet chemical analytical methods and/or instrumental methods. Instrumental neutron activation analysis (INAA) is capable of analyzing samples nondestructively. As a part of a chemical quality control exercise, Zircaloys 2 and 4, nimonic alloy, and zirconium oxide samples were analyzed by two INAA methods. The samples of alloys and oxides were also analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES) and direct current Arc OES methods, respectively, for quality assurance purposes. The samples are important in various fields including nuclear technology. Methods: Samples were neutron irradiated using nuclear reactors, and the radioactive assay was carried out using high-resolution gamma-ray spectrometry. Major to trace mass fractions were determined using both relative and internal monostandard (IM) NAA methods as well as OES methods. Results: In the case of alloys, compositional analyses as well as concentrations of some trace elements were determined, whereas in the case of zirconium oxides, six trace elements were determined. For method validation, British Chemical Standard (BCS)-certified reference material 310/1 (a nimonic alloy) was analyzed using both relative INAA and IMNAA methods. Conclusion: The results showed that IM-NAA and relative INAA methods can be used for nondestructive chemical quality control of alloys and oxide samples.
Sharp coefficient inequalities for certain subclasses of bi-univalent Bazilevi\v{c} functions
Amol Bhausaheb Patil 대한수학회 2022 대한수학회논문집 Vol.37 No.1
In the present paper, we introduce the subclasses $\mathfrak{B}_{1\Sigma}(\mu)$, $\mathrm{B}_{1\Sigma}(\mu,\gamma)$ and $\mathit{U}_{\Sigma}(\mu,\gamma)$ of bi-univalent Bazilevi\v{c} functions which are defined in the open unit disk $\mathbb{D}$. Further, we obtain sharp estimates on initial coefficients $a_2$, $a_3$, $a_4$ and also sharp estimate on the Fekete-Szeg\"{o} functional $a_3-k{a}_{2}^{2}$ for the functions belong to these subclasses.
Gastric per-oral endoscopic myotomy: Indications, technique, outcomes, and future directions
Amol Bapaye,Nachiket A. Dubale 소화기인터벤션의학회 2020 Gastrointestinal Intervention Vol.9 No.2
After the clinical success of per-oral endoscopic myotomy (POEM) for treatment of achalasia cardia, the principle of submucosal tunneling and mucosal flap valve has been used in several other areas of the gastrointestinal tract. Gastric per-oral endoscopic pyloromyotomy (G-POEM, POEP, POP) is a relatively new procedure described for the treatment of refractory gastroparesis. This review discusses the indications, patient selection, pre-procedure workup, and procedure details of G-POEM. It also reviews the current literature on this procedure and provides insights and future directions for research on this topic.

Software reliability testing plays a vital role to identify many flaws in software design as well as functional aspects. Reliability testing encompasses the analysis of the software’s capacity to carry out intended tasks, particular environmental conditions within the given time instance. So, reliability estimation should be carried out within the initial stage of the software development. Through this paper we have shown the importance of the testing time and testing coverage in the analysis of software reliability. Testing time is the time interim required to carry out testing mechanism. Testing coverage includes the amount of tests exercised by the test set or batch. In order to enhance the efficiency of the proposed system we have applied the non-homogeneous Poisson process.

Amol K. Kadam,S.D. Joshi,Debnath Bhattacharyya,Hye-Jin Kim 보안공학연구지원센터 2016 International Journal of Software Engineering and Vol.10 No.11
Software cost estimation is the important activity while the development of the software. Expenditure assessment is bit complex task as it can be affected by many factors. This factors aids in the calculating of maintenance cost of software. In this paper we have implemented the function point analysis and test point analysis in order to discover the maintenance cost. This is accomplished by using the various techniques to calculate the function point analysis and test point analysis. Along with the calculation of maintenance cost we have also presented the module to assess the reliability of the software from the context of white box testing. Software reliability growth models are aids to evaluate the reliability of the software. This paper presented the analysis of code based SRGM to estimate the reliability.

The most important non-functional requirements for dependability of any Embedded Real-Time SafetySystems are safety, availability and reliability requirements. System architecture plays the primary role inachieving these requirements. Compliance with these non-functional requirements should be ensuredearly in the development cycle with appropriate considerations during architectural design. In this paper,we present an application of system architecture modeling for quantitative assessment of systemdependability. We use probabilistic model checker (PRISM), for dependability analysis of the DTMCmodel derived from system architecture model. In general, the model checking techniques do not scalewell for analyzing large systems, because of prohibitively large state space. It limits the use of modelchecking techniques in analyzing the systems of practical interest. We propose abstraction basedcompositional analysis methodology to circumvent this limitation. The effectiveness of the proposedmethodology has been demonstrated using the case study involving the dependability analysis of safetysystem of a large Pressurized Water Reactor (PWR).
