Authors: Tian Li Feng , Yi Shi He , Zhu Yang Zhu , Zhao Yu Xin , He Lin
Published: July 2014

Supersonic turbulent mixing layer requires high spatiotemporal resolution of measuring techniques to study its aero-optical effects. However, the spatiotemporal resolution of existing techniques is not high enough. NPLS-WT (NPLS based wavefront technique) is a new aero-optics measuring technique developed in 2010. Its time resolution is 6ns, and spatial resolution and time correction resolution can reach up to micrometers and 200ns respectively. NPLS-WT was used in this paper to study aero-optical effects induced by Mc=0.5 supersonic mixing layer. The fine wavefront aberration information is revealed by the OPD of high resolution. The results show that the wavefront in near field is not sensitive to the resolution, and large-scale structures play a dominant role on the wavefront in near field. The cumulative effects analysis show us that the density difference between large-scale structures and free stream is the main reason to wavefront aberration, and the larger the vortex is, the more obvious the effect to wavefront aberration is.

Design of Inorganic Scintillators: Role of Thermoluminescence
Authors: Gartia R.K.
Published: July 2014

Thermoluminescence (TL) is basically a super-sensitive phenomenon exhibit ted practically by all semiconductors/ insulators upon suitable excitation. The occurrence of TL peaks during the thermal scan of a previously excited material gives rise to a number of peaks whose trapping parameters and relative concentrations can be evaluated by well-known techniques. Thus, TL in principle is a unique tool to characterize scintillator crystals. The technique is capable to detect the relative abundance of carriers in traps as shallow as ≈0.1eV to as deep as 2.0eV; providing means to probe carriers having lifetime (τ) as low as ∼ps to as large as billions of years. Hence the technique can be used to design scintillator materials of desired properties specially the decay time, the rise-time and the afterglow by adjusting the presence/absence of relevant trapping levels.
The Influence of Equivalent Contact Area Computation in Extended Node to Surface Contact Elements
Authors: Wautelet Gaetan , Ponthot Jean Philippe
Published: July 2014

This article aims at extending the node to surface formulation for contact problems withan area regularization as proposed by [1]. For that purpose, two methods are proposed to computethe equivalent contact area attributed to each slave node. The first method, which is based on a geo-metrical approach through force equivalence, is an original extension of the one proposed in [1] fortwo-dimensional contact problems, i.e. plane stress and plane strain state, to the axisymmetric mod-elling context. The second method relies on an energy consistent way obtained through the virtualwork principle and the same expression for the equivalent contact area as the one originally cited in[2] is then recovered. First, the node to surface strategy with area regularization is introduced and theaforementioned methods for the equivalent contact area are presented in detail and compared. After-wards a consistent linearization technique is applied to achieve a quadratic convergence rate in theNewton Raphson iterative procedure used to solve the non-linear equilibrium equations of the under-lying finite element model. Finally, two axisymmetric numerical examples are provided in order tocompare the aforementioned equivalent contact area evaluations and to demonstrate the performanceand the robustness of the consistent approach especially in the neighbourhood the revolution axis.

Authors: Graciani Enrique , Mantič Vladislav , París Federico
Published: July 2014

Relations between different solutions of an interface crack in a neighborhood of the crack tip given by the open model, frictionless and frictional contact models of interface cracks are analyzed numerically for a penny-shaped interface crack subjected to remote tension. A new analytic expression for the size of the near-tip contact zone in presence of Coulomb friction between crack faces is proposed in the so-called case of the contact zone field embedded in the oscillatory field.
Nonlinear Time Spectral Analysis for a Dynamic Contact Model with Buckling for an Elastic Plate
Authors: Muradova Aliki D. , Stavroulakis Georgios E.
Published: July 2014

In the present paper a dynamic nonlinear model with contact and buckling for an elasticplate is considered. The model consists of two coupled nonlinear hyperbolic type partial differentialequations. The plate is subjected to compressive and/or tensile moving loads on its edges. The foundationsare nonlinear elastic Winkler and Pasternak models. The initial-boundary value problems forthe model are solved with the use of the time spectral method for spatial discretization and after thediscretization the Newmark- time-stepping iterative scheme for the obtained system of nonlinear ordinarydifferential equations. The model is tested for the Winkler-type and shear Pasternak-type andas well for several values of the physical constants of the foundations.

The use of storytelling in quantitative research reports: A marketing research firm perspective
Authors: Maritz Vanessa , Petzer Daniel J. , De Meyer Christine
Published: July 2014

Orientation: Actionable reporting ensures that a marketing research firm communicates with clients to achieve business impact as opposed to merely communicating data to clients. Storytelling communicates with impact as it focuses on creating engagement and inspiring action.Research purpose: This article investigates the use of storytelling as a tool for actionable reporting by South African marketing research firmsMotivation for the study: Clients of marketing research firms often criticise research reports as being too technical and lacking in strategic value. Storytelling is a reporting technique that can be used to develop actionable research and provide clients with more strategic value. Research design, approach and method: A total of 26 in-depth qualitative interviews were conducted with client service directors and managers of marketing research firms that deliver quantitative research reports to clients.Main findings: Results indicated that all marketing research firms but one use storytelling. Barriers that impede more regular use are inexperienced research executives and the time intensity associated with creating stories.Practical/managerial implications: Storytelling should be used by marketing research firms to provide clients with more actionable research.Contribution/value-add: The study provides marketing research firms in South Africa with recommendations as to how to implement storytelling as a reporting technique, which will add value to clients and enable marketing research firms to remain competitive and develop relationships with clients.
The impact of spousal violence on the children: A pastoral care approach
Authors: Sifo Luvuyo G. , Masango Maake J.
Published: July 2014

This article investigates the impact of spousal violence on children. Spousal violence in the home affects children negatively and its impact goes beyond their childhood years into adulthood. Some children become dysfunctional in life as a result of their exposure to violence between their parents. These children may exhibit symptoms associated with post-traumatic stress disorder (PTSD) later on in life. A case study of a family exposed to violence was undertaken. Findings from this case scenario were measured against existing literature. A pastoral care method of responding to the victims is proposed in order for them to be healed.
Peripheral nerve injury grading simplified on MR neurography: As referenced to Seddon and Sunderland classifications
Authors: Chhabra Avneesh , Ahlawat Shivani , Belzberg Allan , Andreseik Gustav
Published: July 2014

The Seddon and Sunderland classifications have been used by physicians for peripheral nerve injury grading and treatment. While Seddon classification is simpler to follow and more relevant to electrophysiologists, the Sunderland grading is more often used by surgeons to decide when and how to intervene. With increasing availability of high-resolution and high soft-tissue contrast imaging provided by MR neurography, the surgical treatment can be guided following the above-described grading systems. The article discusses peripheral nerve anatomy, pathophysiology of nerve injury, traditional grading systems for classifying the severity of nerve injury, and the role of MR neurography in this domain, with respective clinical and surgical correlations, as one follows the anatomic paths of various nerve injury grading systems.
