An efficient effort and cost estimation framework for Scrum Based Projects
Authors: Arora Mohit , Sahil Verma Dr. , Kavita Dr. 
Published: November 2018

Software Process Models from its inception instill standardization and creates a generic culture of developing software for various IT industries. A great paradigm shift has been observed in terms of embracing Agile Development methodology as a viable development methodology in cross key business units. There is a buffet of agile methodologies comes under the umbrella of ASD, out of which Scrum got the highest popularity and acceptability index. Agile based software development is the need of immediate environment. There is an increasing demand for significant changes to software systems to meet ever-changing user requirements and specifications. As Agile is volatile, so effort estimation is challenging and still striving for perfection to decide size, effort, cost, duration and schedule of projects with minimum error. This cause sensitizes potential researchers all across the globe to start working on addressing the issue of inaccurate predication of efforts. The gap between estimated and actual effort is because of limited or no inclusion of various estimation factors like people and project related factors, inappropriate use of size metric and cost drivers, ignorance of testing effort, team member’s inability to understand user story size and complexity etc. This paper attempts to bridge the gap of estimated and actual effort by the use of soft computing techniques thus taking the research to advance frontier area in terms of estimation.

Published: November 2018

Fossil fuel saving is part of the 21th century goal. One of the largest sectors that consumes energy is the building sector since it consumes 40% of the total energy in Europe through heating and cooling. Thus, the need of minimizing the energy consumption played an important role in the development of building insulation materials. Selection of a proper material for building insulation differs according to the building surrounding climate and the properties required in the material. Building climate determines the insulating material location whether its internal or external while properties can differ according to many parameters that affect the material quality such as thermal insulation, acoustic insulation, waterproofing, resistance to fire and mechanical properties. Another factor is newly considered which doesn’t affect the product quality but has an influence in the energy consumption is the environmental impact. The aim of the research is considering most of the above factors through making a composite of rice straw particles bounded by a polymer to produce roof insulations. The utilization of wastes such as rice straw to produce a high quality product with the least price is the research main objective. The polymers selected for research are the unsaturated polyester resin and the polyurethane foam polymers. The polyester is not recently applied for insulation on comparison with the polyurethane foam which is dominant through the global market. At the end of the research, satisfying results have been achieved to nominate the 80% polyurethane foam and 20% rice straw composite as the best sample among all of the prepared samples. The other samples include polyester and rice straw composite with different compositions. The foam and straw sample have the best insulation with value of 0.1627 W/m oC. The compression strength has also been improved on addition of rice straw to the polyurethane foam by three times the initial value. Also, the density measurement revealed a very light composite which is suitable for the construction field requirements. This results in reducing the cost by 28.35%. On contrast, polyester samples which have very high density and higher K factor are not so efficient, so it is suggested that they can be applied at rural regions due to their low cost.
Discretization Analysis of a Composite GFRP Cylinder
Authors: V K N S N Moorthy CH , Srinivas V 
Published: November 2018

Conventional Steel Cylinders used for LPG cylinder for domestic applications are not manufactured in a single joint but are welded. While composite cylinders are manufactured in a single joint, Composite components cannot be welded like the steel cylinder. Composite Cylinders are winded using Filament Winding technique. Compared to Steel Cylinders, Composite Cylinders are costlier. As composite cylinders are safer than steel cylinder, composite Cylinders due to a rubber lining inside, they are 100% leak proof. If mass production of composite cylinders are done then the cost may get reduced. This paper summarizes the design and analysis of the manufacturing of Liquid petroleum gas (LPG) Cylinder using Glass Fibre Reinforced Plastic (GFRP) material. The stresses along all the directions of the ply sequence are also calculated using Classical Lamination Theory (CLT). The fibre stresses along all the directional angles were found to be under the required stress limits. The Metallic boss Calculation & angle variation at dome is the key parameter and is carried out and determined the tip radius.
Engineering Design of Bird Fauna of Water Spills in Kazalinsk
Authors: S. Sikhanova N. , I. Rakhimov I. 
Published: November 2018

Preservation of biodiversity (interspecific, intraspecific) is one of the urgent tasks that requires a systematic, comprehensive, scientifically based approach. Engineering design of the bird life area, includes modeling, packaging the area and its effects on environment. For this purpose we design the procedure by finite element method for biological life of bird. A vivid example of restoration and preservation of biological diversity of fauna and flora should be considered the implementation of the environmental project "Regulation of the riverbed of the Syrdarya and the Northern Aral Sea”. The project was initiated by well-known Russian and Kazakh scientists with the support of the government of Kazakhstan and world financial institutions. The aim of the project is the construction of new and reconstruction of existing hydrological structures. The result of this project, among other things (improving the economic, social, environmental situation) is the restoration of biological diversity. The process of recovery is gradual, depends on many external factors and requires detailed study, scientific justification for individual periods and phases. Bird fauna is considered conservative enough in the choice of habitats and is an indicator of the restoration of biodiversity. This paper is devoted to keeping track of bird in the water spills of the Baskara canal (the main left-bank channel of the Syrdarya river) in the eastern part of the Kazalinsky district (Kazakhstan's Aral Sea area). During the surveys, 13 species of birds were recorded, which are representatives of 8 orders. The most part (77%) of registered birds belongs to the limnophilic group - the wetland birds. Impoverished species composition is due to the climatic conditions of the accounting year, the lack of sufficient shelter, the isolation of the water body. Systematic, all-season bird monitoring is required.

Authors: R. Girish C. , . . 
Published: November 2018

The water contamination is an important crisis which is to be addressed in the recent time. The pollutants present in wastewater are treated by adsorption using activated carbon, which is considered as one of the effective method. The adsorbent has to be modified to improve the adsorption capacity and the surface properties. Various methods such as physical, chemical treatment, impregnation and functionalization techniques are available. Impregnation is one of the effective method carried out for surface modification and to increase the adsorption capacity. Therefore, current study investigates the different impregnation methods used for the surface modification of the adsorbent. It also reviews the various precursors used for adsorbent preparation, the impregnating agent, the operating conditions and the adsorption capacity of the adsorbent.Â Â
Money, Refuge, and Justice
Authors: Blake Michael 
Published: November 2018

Abstract
Margit Osterloh and Bruno S. Frey have introduced a novel, and potentially powerful, vision of migration rights, on which European states might respond to the current crisis of migration by conditioning admission on the payment of an entry fee. In this comment, I raise a worry about the morality of a world governed by such a principle. While Osterloh and Frey foresee a world in which migration is made more sustainable, with benefits for all stakeholders as a result, I am worried their program would lead to a lessening of support for the moral principles that gave rise to the 1951 Convention Relating to the Status of Refugees. This Convention, I argue, ought to be preserved as a public statement of the principle that wealthy states have an obligation to bear some costs in the defense of human rights; Osterloh and Frey, I argue, might be undermining support for those moral principleswe currently have the most need to reinforce. Nevertheless, I argue that under emergency circumstances we might have a need for experimentation and political innovation, even if we are confident that what they produce will necessarily involve some degree of political wrongdoing; we might, in short, have a reason to try out proposals of the sort Osterloh and Frey defend, even if the moral worries I defend here are correct.
Can an Entrance Fee Solve the Migration Problem? Probably Not
Authors: Althammer Jörg , Sommer Maximilian 
Published: November 2018

Abstract
Refugee and poverty migration is one of the key challenges developed Western societies are facing. Due to the unstable political situation in many parts of the world and the lasting high differences in development between the economies, these migratory movements will continue to increase in the future. In order to channel immigrants, the authors suggest that migrants must pay an entry premium to obtain a permanent right of residence.We criticize this proposal from both an ethical and an economic perspective. We argue that a pricing system is neither ethically legitimate nor economically sensible. In order to meet the challenges of migration, a fundamental change in economic cooperation between developed and less developed economies is more appropriate.
Towards a Rational Migration Policy
Authors: Söllner Fritz 
Published: November 2018

Abstract
A rational migration policy has to be based on a coherent set of objectives and its instruments have to be chosen so as to best achieve these objectives. If the focus of migration policy is on the interests of the receiving country, it has to be decided, firstly, how many and what kind of immigrants are to be invited and, secondly, how many refugees are to be accepted for humanitarian reasons. The former are supposed to live permanently in the receiving country, while the latter may stay only temporarily. For the determination of these objectives, the economic and the non-economic consequences of immigration for the native population need to be analyzed. As there will be conflicts of interest, an open debate about the objectives of migration policy is necessary. In particular, it needs to be acknowledged that economic self-interest motivates, at least in part, both the critics and the proponents of immigration. Only when objectives have been agreed upon, can the appropriate instruments be chosen. Among those, the instrument of the entrance fee may play an important role, especially with regard to selecting qualified immigrants.
A Pragmatic Approach to Migration

This reply focusses on three aspects: advantages and disadvantages of our proposed ‘cooperative entry certificates’ for the countries of origin, for the migrants, and for the host countries. It analyzes in what respects our proposal can be improved based on the valuable points made by the commentators. In addition, the question of how to deal with winners and losers within the three groups is discussed.
Crowdlaw: Collective Intelligence and Lawmaking
Authors: Noveck Beth Simone 
Published: November 2018

Abstract
To tackle the fast-moving challenges of our age, law and policymaking must become more flexible, evolutionary and agile. Thus, in this Essay we examine ‘crowdlaw’, namely how city councils at the local level and parliaments at the regional and national level are turning to technology to engage with citizens at every stage of the lawand policymaking process. Aswe hope to demonstrate, crowdlaw holds the promise of improving the quality and effectiveness of outcomes by enabling policymakers to interact with a broader public using methods designed to serve the needs of both institutions and individuals. crowdlaw is less a prescription for more deliberation to ensure greater procedural legitimacy by having better inputs into lawmaking processes than a practical demand for more collaborative approaches to problem solving that yield better outputs, namely policies that achieve their intended aims. However, as we shall explore, the projects that most enhance the epistemic quality of lawmaking are those that are designed to meet the specific informational needs for that stage of problem solving.

Moral Objectivity and Property: The Justice of Liberal Socialism
Authors: Holt Justin P. 
Published: November 2018

Abstract
This paper restates the thesis of ‘The Requirements of Justice and Liberal Socialism’where itwas argued that liberal socialism best meets Rawlsian requirements of justice. The recent responses to this article by Jan Narveson, Jeppe von Platz, and Alan Thomas merit examination and comment. This reply shows that if Rawlsian justice is to be met, then non-personal property must be subject to public control. If just outcomes merit the public control of non-personal property and this control is not utilized, then justice has been subordinated to the objectively less important institution of private property.
Three-Phase Reactor Model for Simulation of Methylacetylene and Propadiene Selective Hydrogenation Process
Authors: Ahmadi A. R. , Samimi F. , Rahimpour M. R. 
Published: November 2018

AbstractIn this study, an effort was performed to improve methylacetylene and propadiene (MAPD) hydrogenation process with investigation of operating conditions which significantly influence the reactor performance. For this purpose, the operational parameters including concentration of components in the feedstock as well as hydrogen and diluent (recycle stream) flow rates were optimized via differential evolution (DE) technique to maximize propylene (PR) production, to minimize green oil formation as well as to control PR selectivity. Then a comparison was made between the optimized and non-optimized (design) conditions. The results indicate that in optimal conditions, PR production rate increases 5.3 ton/day, while the green oil formation as well as propane (PN) production, as unwanted byproducts are reduced to 0.05 and 0.85 ton/day in comparison with the design conditions. Reduction of undesirable byproducts and enhancement of propylene production rate, demonstrate superiority of the optimized conditions to design conditions.

Regulatory effect of hsa-miR-5590-3P on TGFβ signaling through targeting of TGFβ-R1, TGFβ-R2, SMAD3 and SMAD4 transcripts
Authors: Abedini Bakhshmand Elham , Soltani Bahram Mohammad 
Published: November 2018

Abstract
Transforming growth factor-β (TGFβ) signaling acts as suppressor and inducer of tumor progression during the early and late stages of cancer, respectively. Some miRNAs have shown a regulatory effect on TGFβ signaling and here, we have used a combination of bioinformatics and experimental tools to show that hsa-miR-5590-3p is a regulator of multiple genes expression in the TGFβ signaling pathway. Consistent with the bioinformatics predictions, hsa-miR-5590-3p had a negative correlation of expression with TGFβ-R1, TGFβ-R2, SMAD3 and SMAD4 genes, detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Then, the dual luciferase assay supported the direct interaction between hsa-miR-5590-3p and TGFβ-R1, TGFβ-R2, SMAD3 and SMAD4-3′UTR sequences. Consistently, the TGFβ-R1 protein level was reduced following the overexpression of hsa-miR-5590-3p, detected by Western analysis. Also, hsa-miR-5590-3p overexpression brought about the downregulation of TGFβ-R1, TGFβ-R2, SMAD3 and SMAD4 expression in HCT-116 cells, detected by RT-qPCR, followed by cell cycle arrest in the sub-G1 phase, detected by flow cytometry. RT-qPCR results indicated that hsa-miR-5590-3p is significantly downregulated in breast tumor tissues (late stage) compared to their normal pairs. Altogether, data introduces hsa-miR-5590-3p as a negative regulator of the TGFβ/SMAD signaling pathway which acts through downregulation of TGFβ-R1, TGFβ-R2, SMAD3 and SMAD4 transcripts. Therefore, it can be tested as a therapy target in cancers in which the TGFβ/SMAD pathway is deregulated.
Realisation of Adaptive Hysteresis Current Controller for Performance Improvement of Vector Control Based IPMSM Drive System
Authors: Naik Amiya , Panda A.K. , Kar S.K. 
Published: November 2018

AbstractThe torque ripple, current fluctuation and variable switching frequency of conventional hysteresis current controller (CHCC) under different loading condition and motion variation is inevitable, which demands effective implementation of the existing current controller by which it will be possible to get rid of these limitations. This paper presents enhancement in performance of a vector controlled based Interior Permanent Magnet Synchronous Motor (IPMSM) drive system by using an adaptive hysteresis current controller (AHCC). This controller minimizes torque ripple, current error and is capable of providing nearly constant switching frequency by modifying its bandwidth according to the changes in the system parameter or when the system is subjected to any kind of disturbances and load variation. Initially the study is carried out in MATLAB-Simulink environment and then the test result is experimentally validated through hardware implementation with the help of DSP TMS320F2812 which provides a complete digital control system with high effectiveness and fast computational skill.
Understanding Investor Behavior in the Recent Global Land Rush
Authors: Rosete Alfredo R. M. 
Published: November 2018

Abstract
A sharp rise in land acquisitions in developing countries during the last decade has drawn the attention of scholars and think tanks. Recent empirical literature finds that investors acquiring land tend to target countries that have little regard for local land rights. This is a puzzle. By locating in such countries, investors may be foregoing other advantages that generate more revenue. In this paper, I provide an explanation of investor behavior using a game-theoretic model where investors can use expropriation as a credible threat vis a vis smallholders. I show that the credible threat of expropriation lowers the investor’s cost of locating to a country by reducing the necessary remuneration to smallholders for access to land, resulting in adverse incorporation. Further, I demonstrate that investors will locate in countries with weak land governance whenever they anticipate similar levels of revenue or investor protection.

Using Imagery to Improve Sub-Domains of Physical Literacy
Authors: Guerrero Michelle D. , Chandler Krista 
Published: November 2018

Abstract
A 4-week quasi-experimental intervention was conducted to examine the effects of imagery on sub-domains of physical literacy (i.e., motivation, confidence, perceived physical competence, and motor competence). Children (N = 9; Mage
= 9.11, SD = 0.60) from two sport programs participated in the study. Those in the imagery + physical practice condition received imagery training sessions coupled with physical practice, while those in the physical practice condition only received physical practice. Frequentist and Bayesian statistics showed no between-condition differences at post-intervention; however, results showed that the imagery + physical practice condition reported greater perceived physical competence and received higher scores on motor competence from pre- to post-intervention. Implications for physical activity stakeholders are discussed.
