Review Paper on Experimental and Simulation of Single Point Cutting Tool with Taguchi Method

The experimental results reveal that the most factors liable for increasing cutting temperature square measure cutting speed (v) and depth of cut (d) respectively. Various researches are undertaken in measuring the temperatures generated during cutting operations. Investigators created attempt to live these cutting temperatures with varied techniques throughout machining.. Single point cutting tool has been solid modelled by using SOLIDWORKS 2013 and Finite Element Analysis carried out by using ANSYS Workbench 15. By varied parameters the result of these on temperature are compared with the experimental results and FEA results.

Developing early learners' creativity and collaboration using iPads

Continuing developments in technology and consequent societal changes have been accompanied by calls for education to emphasise 21st century competencies such as critical thinking, communication, collaboration, and creativity. These competencies are reflected in the general capabilities of the Australian Curriculum and are to be developed across all learning areas. The study from which this paper is drawn investigated how teachers might use iPads to support development of creativity and collaboration in an early primary classroom. The study used primarily observational methods to describe the pedagogical practices of a teacher working in a shared teaching arrangement with 25 Year 2 students and access to 6 iPads. The focus was on discovering and describing effective approaches to enhancing creativity and collaboration in young learners. Results suggest that learning activities using iPads can be successful in separately developing creativity and collaboration among early learners but that learners were less likely to manifest both creativity and collaboration in the same activity. Implications of the findings are discussed

Model Studies on Footing Beam Resting on Geogrid Reinforced Soil Bed

Geogrid reinforcement below foundation (resting on layered soil conditions having less bearing capacity) to support footing has considerable effect on shear, settlement and cost reducing alternative to conventional method of support. Therefore, in the present paper, a 2D finite element soil- foundation interaction modeling of a square footing has been carried out to investigate the effect of types of geogrid on sttlement, contact presseure and elastic strain.  Performance level of geogrids made from three different types of polymer polypropylene, polyester and non-polymer (PP, PET and NP) have been analysed. Foundation system consists of a square footing beam resting on layered soil conditions (upper compacted and lower loose). Geogrid reinforcement is provided between upper dense soil and lower loose soil and has been assumed to have finite bending stress and, therefore, idealized as a beam. Both soil layers are also assumed to have finite bending stresses. Analysis is carried out by using a computer software program ANSYS with a two dimensional linear 8-noded isoparametric element. The result of analysis is compared with both the systems (foundation system with geogrid reinforcement & without geogrid reinforcement) and optimum thickness and optimum depth of placement of geogrid reinforcement have been found. It is found that use of geogrid and the types of geogrid affect the behavior of the foundation system significantly. Keywords: Footing beam; Geogrids; Settlement; Contact Pressure

Sweeping of the fetal membranes and its effect on duration of pregnancy in low risk cases

Background: This study aimed to determine effectiveness of sweeping of membranes on the duration of pregnancy at term, and its effect on maternal and neonatal outcomes.Methods: In this prospective study, 145 women with uncomplicated pregnancy at 39 weeks or more gestation who were attending regular ANC clinic, were recruited for study, out of them 60 were cases (sweeping group) and 85 were control (no sweeping group). Primary outcome measure was occurrence of spontaneous labour and total duration of pregnancy. Other outcome measures included were interval of onset of labour from membrane sweeping, incidence of premature rupture of membranes, total duration of active labour, mode of delivery, rate of caesarean section and causes, and neonatal and maternal outcome.Results: There were no statistically significant differences between the two groups regarding maternal age, parity and bishops score at recruitment. There was a significant difference observed in spontaneous labour rate and interval time between recruitment to delivery in groups. There was no significant difference regarding mode of delivery, maternal and fetal outcomes.Conclusions: Membrane sweeping is a safe procedure that reduces the incidence of post-term pregnancies if applied at term

Development of a web-based teaching resource for analytical science practitioners

This paper describes the production of multimedia teaching material aimed at working analysts in the water industry who are studying the Open University‟s Foundation Degree in Analytical Sciences. In collaboration with staff at Scottish Water, Edinburgh laboratories, audio and video materials were produced which demonstrate a number of basic laboratory techniques routinely carried out in chemistry and microbiology laboratories. Teaching laboratory techniques (and associated safety procedures) is by its very nature a visual process, and requires the cultivation of a skill base and good practice that can only be gained by repetition. However an initial „show and tell‟ stage is required. This is extended to coverage of aspects of laboratory management, and how analysts work in teams to produce analytical data for the customer

Modeling and Analysis of Discrete Response Data: Applications to Public Opinion on Marijuana Legalization in the United States

This chapter presents an overview of a specific form of limited dependent variable models, namely discrete choice models, where the dependent (response or outcome) variable takes values which are discrete, inherently ordered, and characterized by an underlying continuous latent variable. Within this setting, the dependent variable may take only two discrete values (such as 0 and 1) giving rise to binary models (e.g., probit and logit models) or more than two values (say $j=1,2, \ldots, J$, where $J$ is some integer, typically small) giving rise to ordinal models (e.g., ordinal probit and ordinal logit models). In these models, the primary goal is to model the probability of responses/outcomes conditional on the covariates. We connect the outcomes of a discrete choice model to the random utility framework in economics, discuss estimation techniques, present the calculation of covariate effects and measures to assess model fitting. Some recent advances in discrete data modeling are also discussed. Following the theoretical review, we utilize the binary and ordinal models to analyze public opinion on marijuana legalization and the extent of legalization -- a socially relevant but controversial topic in the United States. We obtain several interesting results including that past use of marijuana, belief about legalization and political partisanship are important factors that shape the public opinion.Comment: 35 Pages, 4 figures, 6 table

XCDCC: Core Excitation in the Breakup of Exotic Nuclei

The eXtended Continuum Discretized Coupled Channel (XCDCC) method is developed to treat reactions where core degrees of freedom play a role. The projectile is treated as a multi-configuration coupled channels system generated from a valence particle coupled to a deformed core which is allowed to excite. The coupled channels initial state breaks up into a coupled channels continuum which is discretized into bins, similarly to the original CDCC method. Core collective degrees of freedom are also included in the interaction of the core and the target, so that dynamical effects can occur during the reaction. We present results for the breakup of $^{17}$C=$^{16}$C+n and $^{11}$Be=$^{10}$Be+n on $^{9}$Be. Results show that the total cross section increases with core deformation. More importantly, the relative percentage of the various components of the initial state are modified during the reaction process through dynamical effects. This implies that comparing spectroscopic factors from structure calculations with experimental cross sections requires more detailed reaction models that go beyond the single particle model.Comment: 14 pages, revtex, submitted to Phys Rev
