Savings, investment and growth in India: an application of the ARDL bounds testing approach

This paper considers savings, investment and economic growth for India using annual time series data for the period 1950/51 to 2003/04. The analysis uses Perron’s innovational outlier model to conduct unit root tests which endogenously determines a structural break. The empirical results show that the null hypothesis of unit root cannot be rejected for gross domestic product. Moreover, the results show that the most significant structural breaks over the last five decades correspond to the wars, regime change and the nationalisation of the banks. The study also utilises the Autoregressive Distributed Lag (ARDL) approach to test for cointegration. Whilst the results support the existing evidence for the Carroll-Weil hypothesis; the study also finds that saving unambiguously determines investment in both the short and long runs. No evidence is found to support the commonly accepted growth models in India, that investment is the engine of economic growth.

Single phase Cascaded multi level Inverter Using PIC Microcontroller

--Multilevel inverters have recently found its way in to the high power applications in both domestic and industrial fields with its ability of low switching frequency. Out of all the topologies of a multilevel inverter, the cascaded H-bridge inverter is most commonly used due to its modular topology. This inverter is called the developed cascaded multilevel inverter. In order to generate all voltage levels (even and odd) at the output, four different algorithms are proposed to determine the magnitude of dc voltage sources. The ability of the proposed inverter to generate all voltage levels (even and odd) is reconfirmed by using the experimental results of a 5-level inverter. The switching is done by PIC microcontroller. Topology is designed with minimum size, weight & reduced power losses.
7.4.1 Rapid Development Case Study: Lessons Learned From Arming the C‐145 Skytruck

This paper examines Project “Tropic Thunder,” a US Air Force effort to integrate a 0.50 caliber machine gun onto the C‐145 Skytruck. The paper compares the project with relevant literature to determine where the project does and does not alignment with other rapid development models, revealing shortfalls in stakeholder identification and requirements definition that significantly delayed the project. Ultimately, the system works as desired, the design proved to be flightworthy, and the User was happy with the results. However, more up‐front rigor in the systems engineering process could potentially have resulted in a similar level of technical performance, only faster and cheaper. The case depicts the importance of the initial steps in the systems engineering process to the overall success of a rapid development effort.
Effect of cross-sectional geometry on superelasticity of helical nanobelts

Abstract The shape memory effect (SME) and the superelasticity make nanoscale chiral structures such as helical ZnO nanobelts promising for a wide range of important applications. In this paper, based on the non-linear rod model with surface effect (Wang et al, 2011), the effects of surfaces and geometrical size of the cross-section on the superelasticity of the helical nanobelts have been investigated quantitatively. Our results demonstrate the superelasticity of helical nanobelts exhibit a distinct size effect, depending on the cross-sectional geometry. We also show the efficiency of the energy storage and retrieval of the helical nanobelts induced by the superelasticity depends strongly on the cross-sectional geometry.
Clinical comparison of intravenous thrombolysis and bridging artery thrombectomy in hyperacute ischemic stroke with unknown time of onset

Introduction The aim of the study was to explore the clinical efficacy and safety of intravenous thrombolysis and bridging artery thrombectomy for hyperacute ischemic stroke with unknown onset time. Methods One hundred and twenty-eight patients with hyperacute cerebral infarction and without a clear time of onset were randomly divided into intravenous thrombolysis (n = 66) and bridging artery thrombectomy groups (n = 62). Results In the intravenous thrombolysis group, 37 patients’ vessels had recanalization, 32 patients’ 24-hour National Institute of Health Stroke Scale (NIHSS) score improved, and 42 patients’ 90-day modified Rankin Scale (mRS) score was good. In the bridging artery thrombectomy group, 62 patients’ vessels had recanalization, 28 patients’ 24-hour NIHSS score improved, and 38 patients’ 90-day mRS score was good. Conclusions The benefits and adverse events between intravenous thrombolysis and bridging artery thrombectomy for ischemic stroke with unknown time of onset are similar.
The role of hotel architecture in shaping the city’s image

The elements of the environment are characterized by variability. The structure of the city is also a subject to constant structural, social and material transformations. Objects in the city can play significant role for urban landscape. In recent years, it can be observed that the architecture of hotels in cities is becoming more and more unique. After years of building similar hotel facilities, architects began to create more and more original forms that attract the attention of passers-by and are remembered. The importance of individual places in the hierarchy of these space is also changing. Hotels are elements thatbuild the image of cities, often becoming their visual dominant. This applies to creating a sculpture in a space that catch attention with its form and play of colors. The aim of the article is to show, on the example of selected projects, how hotel buildings can shape urban images. The research method is based on the analysis of selected objects and showing their role in shaping the image of the city. The concept of the hotel influences the building of identity. The form of the hotel, the functionality, the materials, and their combination, create the semantic experience for observer. The hotel becomes a ‘story’ narrative that gives visitors or pedestrians a personal feeling of reading architecture. According to Kevin Lynch (1960:8), the external image we perceive can be analyzed by combining three factors: identity, structure and meaning. Identity is identifying an object, distinguishing it from others, making it exclusive. Thus, fragments of space of greater importance are created in the city, which are shaped in terms of public utility. These areas, having greater value, are also of greater prestige for the city. They add as well the aesthetic energy to the city.
A system identification method for simplifying dynamics equations of motion for remotely operated vehicles and towed systems

Computational cost has inhibited the extensive use of dynamic simulations of tethered systems in the early phases of design, preventing application of the tool to assist in making rational system architecture decisions. A method is proposed for greatly reducing the computational requirements through the application of system identification techniques to generate simpler ordinary differential equations which still capture the nonlinear effects of interest. A single degree of freedom example is used to illustrate the method.
Equus roundworms (Parascaris univalens) are undergoing rapid divergence due to host and environment factors

Background The evolution of parasites is often directly affected by the host's environment. Studies on the evolution of the same parasites in different hosts are extremely attractive and highly relevant to our understanding of divergence and speciation. Methods Here we performed whole genome sequencing of Parascaris univalens from different Equus hosts (horses, zebras and donkeys). Phylogenetic and selection analysis was performed to study the divergence and adaptability of P. univalens. Results At the genetic level, multiple lines of evidence support that P. univalens were mainly separated into two clades (Horse-derived and Zebra & Donkey-derived). This divergence began at 300-1000 years ago, and we found that most of the key enzymes related to glycolysis were under strong positive selection in zebra & donkey-derived roundworms, but lipid related metabolism system was under positive selection in the horse-derived roundworms, indicating that the adaptive evolution of metabolism may drive the divergence in past few centuries. In addition, we found that some drug-related genes have a significantly higher degree of selection in different populations. Conclusions This work reports evidence that the host’s diet drives the divergence of roundworms for the first time, and also supports that divergence is a continuous and dynamic process, and continuous monitoring of the effects of differences in nutritional and drug history on rapid evolution of roundworms are conducive to further understanding host-parasite interactions.
Agent-based manufacturing control based on distributed bid selection and publish-subscribe messaging: a simulation case study

Bidding-based negotiation schemes play a major role in multi-agent manufacturing systems research. Despite some concerns with message congestion, researchers have been proposing and studying negotiation schemes based on the contract net protocol (CNP). On the other hand, research in robotics has considered a variant of CNP based on publish-subscribe messaging designed for multi-robot coordination. A distinct feature of this variant involves distributing the bid evaluation and selection functions among robot agents. This paper discusses our adaptation of this design variant for multi-agent manufacturing systems and examines its performance implications. Using discrete-event simulation, we study how the adapted CNP design can help address the message congestion problem by cutting down on negotiation slack time. Our case study results show that it can enhance the resilience of the agent negotiation process to message congestion, thereby contributing to the overall performance of a multi-agent manufacturing system.

PARVUS – miniaturised robot for improved flexibility in micro production

Purpose – Until now, the size range of most machines for precision assembly was much larger than the size of the pieces to be handled or the necessary workspace. Flexibly scalable miniaturised production machines can help to develop much more flexible micro production systems. The paper aims to describe the development of a micro‐parallel‐SCARA robot adapted in size to MEMS products.Design/methodology/approach – The robot consists of a miniaturised parallel structure, which provides a high level of accuracy in a workspace of 60 × 45 × 20 mm3. It has a base area of 130 × 170 mm2 and offers four degrees of freedom.Findings – Based on simulations, the degree of miniaturisation in terms of a smaller structure and a high level of accuracy is determined. The results show that a miniaturised hybrid robot with a plane parallel structure driven by miniaturised zero‐backlash gears and electric motors can reach a theoretical repeatability better than 1 μm. Research limitations/implications – The first prototype provi.
Microstructure and properties of TiB2-reinforced Ti–35Nb–7Zr–5Ta processed by laser-powder bed fusion

The Ti–35Nb–7Zr–5Ta (wt%, TNZT) alloy was reinforced with TiB2 and synthesized by L-PBF. The relatively small TiB2 particles change the solidification structure from cellular to columnar-dendritic and lead to submicron TiB precipitation in the β matrix. This results in pronounced grain refinement and reduction of texture. However, the microstructure of the additively manufactured TNZT-TiB2 is still different from the as-cast, unreinforced TNZT, which contains equiaxed and randomly oriented grains. The β phase is less stable in the as-cast samples, leading to stress-induced martensitic transformation and recoverable strain of 1.5%. The TNZT with 1 wt% of TiB2 presents significantly higher compressive strength (σYS = 495 MPa) compared to unreinforced samples (σYS = 430 MPa), without sacrificing ductility or altering Young’s modulus (E ≈ 46 GPa). The addition of a small fraction of TiB2 to the TNZT alloy synthesized by L-PBF is a promising alternative for manufacturing sophisticated components for biomedical applications.
“Are We an Advisory Board or a Decision Making Entity?”: Teachers’ Involvement in Decision Making in Instructional Leadership Teams

ABSTRACT This study explored teachers’ involvement in decision making processes in instructional leadership teams (ILTs) in three high-poverty high schools. Two factors influenced the extent of teachers’ involvement and authority in decision making processes on the team: 1) the design of teachers’ roles on the ILT and 2) routines used for agenda setting, facilitation, and discussion in ILT meetings. Although administrators often constrained teachers involvement and influence in decision making processes, study findings suggest that more inclusive approaches to involving teachers in decision making can enhance decision quality and are essential for cultivating teachers’ commitment to implementation.
CLASSIFICATION OF CEREAL GRAINS USING MACHINE VISION: III. TEXTURE MODELS

A digital image analysis (DIA) algorithm was developed based on color features to classify individual kernels of Canada Western Red Spring (CWRS) wheat, Canada Western Amber Durum (CWAD) wheat, barley, oats, and rye. Eighteen color features (mean, variance, and range of red, green, and blue, and hue, saturation, and intensity) were used for the discriminant analysis. Grains from 15 growing regions (300 kernels per growing region) were used as the training data set and another five growing regions were used as the test data set. When the first 10 most significant color features were used in the color model and tested on an independent data set (the test data set where total number of kernels used was 10,500; for CWRS wheat, 300 kernels each were selected for three grades), the classification accuracies of CWRS wheat, CWAD wheat, barley, oats, and rye were 94.1, 92.3, 93.1, 95.2, and 92.5%, respectively. When the model was tested on the training data set (total number of kernels used was 31,500), the classification accuracies were 95.7, 94.4, 94.2, 97.6, and 92.5%, respectively, for CWRS wheat, CWAD wheat, barley, oats, and rye.
Improved Two-Dimensional Dynamic Stall Prediction with Structured and Hybrid Numerical Methods

A joint comprehensive validation activity on the structured numerical method elsA and the hybrid numerical method TAU was conducted with respect to dynamic stall applications. In order to improve two-dimensional prediction, the influence of several factors on the dynamic stall prediction were investigated. The validation was performed for three deep dynamic stall test cases of the rotor blade airfoil OA209 against experimental data from two-dimensional pitching airfoil experiments, covering low speed and high speed conditions. The requirements for spatial discretization and for temporal resolution in elsA and TAU are shown. The impact of turbulence modeling is discussed for a variety of turbulence models ranging from one-equation Spalart-Allmaras-type models to state-of-the-art seven-equation Reynolds stress models. The influence of the prediction of laminar/turbulent boundary layer transition on the numerical dynamic stall simulation is described. Results of both numerical methods are compared to allow conclusions to be drawn with respect to an improved prediction of dynamic stall.
Organic Solvent Nanofiltration of Water-in-Oil Pickering Emulsions—What Influences Permeability?

Pickering emulsions (PEs) have received increasing interest for their application in catalytic multiphase reactions. Organic solvent nanofiltration of PEs was shown to be a promising procedure for efficient and effective catalyst recycling. In this work, a systematic parameter study to identify the main influencing parameters on PE filtration was conducted for a large variety of PE compositions for the first time. In addition to temperature, only the type of organic solvent significantly influenced the filtration performance, which could be mathematically modeled via a combination of the solution–diffusion and the resistance in the series model. Particle type and concentration, dispersed phase fraction and the presence of reaction (by-)products did not show any significant impact on the permeability. The stirrer speed only became important when emulsions stabilized by particles without the tendency to form 3D network structures were filtered in long-term filtration experiments. These results pave the way towards the application of PE membrane filtration for catalyst recovery in continuous liquid/liquid multiphase reactions and enable broad operation windows. As the mechanical separation of PEs was shown to be a very robust process, the emulsion composition can now be tuned to meet the needs of the reaction without any (significant) loss in filtration performance.
Implementation of Internal Capital Adequacy and Assessment Process in Vietnamese Commercial Banks

The internal capital adequacy and assessment process (ICAAP) was first introduced in the second pillar of Basel II in 2004 to offset the deficiencies of Basel I and capital adequacy regulations in the first pillar of Basel II. This process is aimed at identifying and measuring risks generated in banks’ activities, and then provides the requirements for internal capital levels and methods to raise capital to deal with these risks. In fact, the implementation of Basel II and ICAAP in Vietnamese commercial banks has attained notable achievements, but it also revealed some major weaknesses. The purpose of this research is to evaluate the implementation of ICAAP in Vietnamese commercial banks in eight components of the ICAAP addressed by Basel II using the survey method and then to simulate the implementation of ICAAP in a Vietnamese commercial bank. From the facts and the simulation of the ICAAP framework in this study, the authors offer some suggestions for Vietnamese commercial banks to implement ICAAP effectively in their banking operations.
Extracto de Acacia farnesiana para el control de larva de Aedes aegypti

Introducción: Aedes aegypti es el principal vector de dengue, chikunguña, fiebre amarilla y zika en el mundo; el control químico es el más utilizado para su prevención, atacando la reproducción del mosquito vector, principalmente mediante la aplicación de insecticidas sintéticos en sus lugares de cría. Sin embargo, el uso de insecticidas sintéticos ha generado resistencia en los mosquitos y diversos problemas ecológicos. Los extractos naturales de plantas con función insecticida son utilizados como alternativa para el control de vectores. El objetivo del presente estudio fue evaluar la actividad larvicida del extracto de vaina de Acacia farnesiana contra larvas de cuarto estadio de Ae. aegypti. Método: el estudio fue desarrollado en el Laboratorio del Instituto Tecnológico Superior de San Pedro, Coahuila, y en el ejido Mayran, San Pedro, Coahuila, México. Para la elaboración del extracto se utilizó la metodología propuesta por INIFAP-CENID-RASPA 1997. Los productos extractados se utilizaron en los bioensayos con larvas de cuarto estadio de Ae. aegypti durante 168 horas. Se transfirieron grupos de 20 larvas en vasos plásticos con 50 mL de agua, luego se aplicó 1 mL de cada uno de los tratamientos de fruto de Acacia farnesiana con concentraciones finales de 15 % (T1), 25 % (T2), 35 % (T3) y 70 % (T4). Para el control químico se utilizó Abate® 1SG (Temefos) al 25 %. Al testigo no se aplicó ningún tratamiento. Para comparar la mortalidad se realizó un análisis de varianza de un factor para cada uno de los estudios (laboratorio y campo) y un análisis de medidas repetidas en el tiempo para la fase de campo. Se desarrolló una prueba de comparación de medias de Tukey. Los análisis se realizaron usando el programa computacional estadístico IBM.SPSS 18, con un nivel de significancia de P ≤ 0.05. Resultados: en el laboratorio, el extracto de A. farnesiana al 35 % de concentración mostró mayor toxicidad contra las larvas de Ae. aegypti obteniendo una mortalidad media de 15.66 (78.3 %), transcurridas las 72 horas después de la aplicación del tratamiento (P ≤ 0.05). De igual forma, en condiciones de campo, el tratamiento al 35 % resultó ser el más efectivo, alcanzando una media de 19.04 (95.2 %) larvas muertas. Discusión o Conclusión: el extracto de A. farnesiana mostró actividad insecticida contra larvas de Ae. aegypti, siendo más efectivo a una concentración de 35 % en condiciones de laboratorio y campo. El efecto larvicida del extracto de A. farnesiana puede ser utilizado como una alternativa factible y sustentable para el control Ae. aegypti en zonas rurales. Sin embargo, es necesario realizar más estudios para identificar los ingredientes activos y el mecanismo de acción presente en las vainas de A. farnesiana para el control de vectores.
A reliable Taylor series solution to the nonlinear reaction-diffusion model representing the steady-state behaviour of a cationic glucose-sensitive membrane

The nonlinear reaction-diffusion model, which represents the steady-state behaviour of a cationic glucosesensitive membrane with consideration of oxygen limitation and swelling-dependent diffusivities of involved species inside the membrane, is discussed. Analytical expressions of substrate concentration of oxygen, glucose, and gluconic acid in planar coordinates at steady-state conditions are derived for all kinetic parameters, and hence the effect of various factors on the responsiveness of the membrane is analysed. Efficient approaches based on the hyperbolic function and Taylor’s series methods are used to derive the approximate analytical solutions of the nonlinear boundary value problem. A numerical simulation was generated by highly accurate and widely used computer generated routines. 8355 SOLUTIONS OF THE SECOND-ORDER NONLINEAR DIFFERENTIAL EQUATION The derived analytical expressions are shown to be in strong agreements with the numerical results established in the literature. It is concluded that each method is a powerful tool for solving high-order boundary value problem in engineering and science.
