Tangible Interfaces for VR Cultural Heritage Application - School House Virtual Museum

Virtual museums are an important medium for the preservation and dissemination of tangible and intangible cultural heritage as well as for education and public engagement. This is even more important now that focus is being shifted from museum exhibits to the visitors’ experience and the increased attention given to their mobility, and the plurality of voices and perspectives represented. To enhance experience and participation new techniques are being developed and multiple senses stimulated. This paper offers venues to unpack the potentials of VR as a pedagogic vehicle when creative and cross-disciplinary experimentation is employed in and around digital museums. Grounded in a particular site of memory, and co-produced with a ‘post-memory generation’, the School House Virtual Museum is associated with private and silenced memories of past civic resistance in Kosovo. Using written and orally narrated stories, images, videos and immersion within a virtually reconstructed physical space, the experience offers a means to explore spaces, narratives, and technologies relevant to a particular cultural memory and heritage. The main aim of the user study, with 37 participants presented in this work, was to investigate the design of the system, focusing on three aspects: usability, User Experience (UX) and education, and the effect of the tangible interface provided to one user group. The results are overall very positive and conﬁrm that the UX holds potential as a learning and education tool whether in museums, schools, or when used independently.
Title : The role of feedback from the auditory cortex in shaping responses to sounds in inferior colliculus

The extensive feedback from the auditory cortex (AC) to the inferior colliculus (IC) supports critical aspects of auditory learning, but has not been extensively characterized. Furthermore, it remains unknown whether and how intra-cortical processing of auditory information propagates to earlier stages in the auditory pathway. Previous studies demonstrated that responses of neurons in IC are altered by focal electrical stimulation and pharmacological inactivation of auditory cortex, but these methods lack the ability to selectively manipulate the activity of projection neurons. Combining viral technology with electrophysiological recordings, we measured the effects of selective optogenetic activation or suppression of cortico-collicular feedback projections on IC responses to sounds. Activation of cortico-collicular feedback generally increased spontaneous activity and decreased stimulus selectivity in IC, whereas suppression of the feedback did not affect collicular activity. To further understand how microcircuits in the auditory cortex may control collicular activity, we tested the effects of optogenetically modulating different cortical neuronal subtypes, specifically parvalbumin-positive (PV) and somatostatin-positive (SOM) inhibitory interneurons. We found that, despite strong effects on sound-evoked responses across the layers of AC, activating either type of interneuron did not affect IC sound-evoked activity. However, suppression of SOMs, but not PVs, weakly increased spontaneous activity in IC. These findings suggest that shaping of sound responses mediated by cortical inhibition does not affect sound processing in IC. Combined, our results identify that activation of excitatory projections, but not inhibitory-driven increases in cortical activity, affects collicular sound responses. Significance Statement Descending projections from the auditory cortex to the auditory midbrain, the inferior colliculus, have been shown to play a critical role in auditory learning and behavior. However, little is known about the details of how this direct feedback shapes neuronal responses to sounds in the inferior colliculus. We found that direct activation of cortico-collicular feedback increased spontaneous and modulated sound-evoked activity in the inferior colliculus. Interestingly, modulation of inhibitory interneuron activity, thereby increasing or decreasing excitatory neuronal activity in the auditory cortex, did not affect sound responses in the inferior colliculus. This work offers evidence that auditory cortex shapes sound responses in the inferior colliculus via direct feedback independently of the activity of cortical inhibitory interneurons.

An improved chip flow model considering cutting geometry variations based on the equivalent cutting edge method

Abstract An improved chip flow model of a nose-radiused cutting tool in oblique turning is developed considering cutting geometry variations based on the equivalent cutting edge method. The model-building procedure divided the arbitrary cutting area engaged with workpiece into a single edge and a nose-radiused cutting edge according to the depth of cut and tool nose radius. The individual effects on the chip flow angle are distinguished by the equivalent cutting edge method and the total chip flow angle obtained. The chip flow angle prediction results obtained under different cutting parameters show good agreement with experimental data.
Tuneable Resonance Properties of Graphene by Nitrogen-Dopant

Doping as one of the popular methods to manipulate the properties of nanomaterials has received extensive application in deriving different types of graphene derivates, while the understanding of the resonance properties of dopant graphene is still lacking in literature. Based on the large-scale molecular dynamics simulation, reactive empirical bond order potential, as well as the tersoff potential, the resonance properties of N-doped graphene were studied. The studied samples were established according to previous experiments with the N atom’s percentage ranging from 0.38%-2.93%, including three types of N dopant locations, i.e., graphitic N, pyrrolic N and pyridinic N. It is found that different percentages of N-dopant exert different influence to the resonance properties of the graphene, while the amount of N-dopant is not the only factor that determines its impact. For all the considered cases, a relative large percentage of N-dopant (2.65% graphitic N-dopant) is observed to introduce significant influence to the profile of the external energy, and thus lead to an extremely low Q-factor comparing with that of the pristine graphene. The most striking finding is that the natural frequency of the defective graphene with N-dopant’s percentage higher than 0.89% appears larger than its pristine counterpart. For the perfect graphene, the N-dopant shows larger influence to its natural frequency. This study will enrich the current understanding of the influence of dopants on graphene, which will eventually shed lights on the design of different molecules-doped graphene sheet.

The equity premium Puzzle :an evaluation of the french case

We examine the existence of an equity premium puzzle in France using both annual and quarterly time series data. We investigate the ability of a representative agent model with a CRRA time-separable utility function and a utility function that displays habit persistence to account for high equity premia. We employ the three main methodologies used in the literature: calibration, Hansen-Jagannathan volatility bounds and GMM estimation of the preference parameters of the representative consumer. The introduction of habit formation improves upon the results but does not resolve the equity premium puzzle in France.

Bacteriological assessments of foodborne pathogens in poultry meat at different super shops in Dhaka, Bangladesh

Poultry is now considered as a major fast-growing source of meat in the world. The consumers demand safe and hygienic products without contamination with pathogenic microorganisms when the production and consumption of poultry meat is gradually increasing. The present study was conducted to assess the bacterial contamination of dressed chicken collected from different supershops in Dhaka, Bangladesh. The chicken samples from S1, S2, M1, M2 and A supershops were analyzed to determine the enteropathogenic bacteria in poultry meat. Three genera of bacteria were isolated from all of the chicken meat samples. These enteropathogens from various organs of dressing chickens were also enumerated. The isolates were presumptively identified as E. coli, Salmonella spp. , and Shigella spp. by conventional culture method. The three enteropathogens were subjected to PCR assay for their confirmation as virulent enteropathogens. Only E. coli isolates were confirmed as pathogenic E. coli (Enterotoxigenic), other isolates were not confirmed as virulent Salmonella spp. , Shigella spp. Results of this study demonstrated that more cautions are recommended for personnel hygiene in processing and handling of poultry and poultry products to prevent occurrence of enterotoxigenic E. coli in dressed poultry meat sold by the supershops in Bangladesh.

Hyperosmotic Stress Initiates AMPK-Independent Autophagy and AMPK- and Autophagy-Independent Depletion of Thioredoxin 1 and Glyoxalase 2 in HT22 Nerve Cells

Background Hyperosmotic stress is an important pathophysiologic condition in diabetes, severe trauma, dehydration, infection, and ischemia. Furthermore, brain neuronal cells face hyperosmotic stress in ageing and Alzheimer's disease. Despite the enormous importance of knowing the homeostatic mechanisms underlying the responses of nerve cells to hyperosmotic stress, this topic has been underrepresented in the literature. Recent evidence points to autophagy induction as a hallmark of hyperosmotic stress, which has been proposed to be controlled by mTOR inhibition as a consequence of AMPK activation. We previously showed that methylglyoxal induced a decrease in the antioxidant proteins thioredoxin 1 (Trx1) and glyoxalase 2 (Glo2), which was mediated by AMPK-dependent autophagy. Thus, we hypothesized that hyperosmotic stress would have the same effect. Methods HT22 hippocampal nerve cells were treated with NaCl (37, 75, or 150 mM), and the activation of the AMPK/mTOR pathway was investigated, as well as the levels of Trx1 and Glo2. To determine if autophagy was involved, the inhibitors bafilomycin (Baf) and chloroquine (CQ), as well as ATG5 siRNA, were used. To test for AMPK involvement, AMPK-deficient mouse embryonic fibroblasts (MEFs) were used. Results Hyperosmotic stress induced a clear increase in autophagy, which was demonstrated by a decrease in p62 and an increase in LC3 lipidation. AMPK phosphorylation, linked to a decrease in mTOR and S6 ribosomal protein phosphorylation, was also observed. Deletion of AMPK in MEFs did not prevent autophagy induction by hyperosmotic stress, as detected by decreased p62 and increased LC3 II, or mTOR inhibition, inferred by decreased phosphorylation of P70 S6 kinase and S6 ribosomal protein. These data indicating that AMPK was not involved in autophagy activation by hyperosmotic stress were supported by a decrease in pS555-ULK1, an AMPK phosphorylation site. Trx1 and Glo2 levels were decreased at 6 and 18 h after treatment with 150 mM NaCl. However, this decrease in Trx1 and Glo2 in HT22 cells was not prevented by autophagy inhibition by Baf, CQ, or ATG5 siRNA. AMPK-deficient MEFs under hyperosmotic stress presented the same Trx1 and Glo2 decrease as wild-type cells. Conclusion Hyperosmotic stress induced AMPK activation, but this was not responsible for its effects on mTOR activity or autophagy induction. Moreover, the decrease in Trx1 and Glo2 induced by hyperosmotic stress was independent of both autophagy and AMPK activation.
Towards process models for goal-based development of enterprise information systems architectures

Enterprises are organisations with multiple business processes; they often use Enterprise Information Systems (EIS) to support these business processes. The concept of an EIS has arisen from the need to deal with the increasingly volatile requirements of modern large{scale organisations. EIS are growing in use and are now being used to support government, health care, and non-pro�fit / non-governmental organisations. The development of EIS has been aff�ected signi�ficantly by the complexity and size of enterprises and their business processes, in addition to the influences of economical, social, and governmental factors. There are many challenges associated with building EIS. Three critical ones identi�ed in the literature are: adequately satisfying organisational requirements; building valid and stakeholder-acceptable business processes; and providing repeatable and rigorous approaches to establish shared understanding of EIS goals. These challenges are diffi�cult to cope with because of the need to deal with diff�erent goals, changes in goals, and the problem of how to transform these goals into system requirements and, ultimately, to an EIS architecture. This thesis contributes a rigorous approach for identifying and describing the enterprise-level requirements of IT developers, managers, and other stakeholders of an enterprise. The approach provides two modelling and tool-supported processes to help establish a rigorous model of EIS goals. It also provides support for transforming goals to a strategic EIS architecture. The approach presented in the thesis is based on the concepts of Goal-oriented software engineering. The thesis presents a novel Process Model, KAOS-B� that extends goal-oriented software engineering approaches with new concepts and techniques for EIS. Further, to support the transition from requirements to an EIS architecture, an EIS Architecture Process Model (EAPM), is designed and evaluated. Using KAOS-B� and EAPM in concert provides a rigorous, repeatable and tool-supported approach for analysing, and designing a strategic EIS architecture. The thesis illustrates the approach with two substantial examples from the health informatics and critical systems domain.
Evaluating the Impact of Brand image and Service Quality on Consumers’ Purchase Intention: A Case of Large Retail Stores

The aim of this research is to find out the relationship between price, brand image, service quality and consumer purchase intention. Normative and informative susceptibility has indirect effect on consumer purchase intention. The results indicate there is a positive effect of brand image and service quality on consumer purchase intention. Price has insignificant relationship on purchase intention. As consumers in large retail stores don't bother prices. According to the research they consider the stores charge reasonable prices. So their purchase depends on image of the brand and service quality. Normative and informative susceptibility have positive effect on brand image.
Energy harvesting with coupled magnetostrictive resonators

We report the investigation of an energy harvesting system composed of coupled resonators with the magnetostrictive material Galfenol (FeGa). A coupled system of meso-scale (1-10 cm) cantilever beams for harvesting vibration energy is described for powering and aiding the performance of low-power wireless sensor nodes. Galfenol is chosen in this work for its durability, compared to the brittleness often encountered with piezoelectric materials, and high magnetomechanical coupling. A lumped model, which captures both the mechanical and electrical behavior of the individual transducers, is first developed. The values of the lumped element parameters are then derived empirically from fabricated beams in order to compare the model to experimental measurements. The governing equations of the coupled system lead to a system of differential equations with all-to-all coupling between transducers. An analysis of the system equations reveals different patterns of collective oscillations. Among the many different patterns, a synchronous state appears to yield the maximum energy that can be harvested by the system. Experiments on coupled system shows that the coupled system exhibits synchronization and an increment in the output power. Discussion of the required power converters is also included.
Improving copper CMP topography by dummy metal fill co-optimizing electroplating and CMP planarization

In this paper, we present a dummy metal fill method based on co-optimization of both ECP and CMP processes. We present the layout dependent, minimum variance algorithm that matches not only metal densities across two-dimensional tiles of layout, but also the perimeters and shapes of metal lines in each tile. Using co-optimization as the fill criterion, our algorithm effectively minimizes the metal height differences as verified by model based CMP simulations. In addition, it also renders pre-characterization of fill constraints with respect to timing and signal integrity assurance. We also show our silicon data measured on a 65nm process that sufficiently provide proof of the method.
Structure and equation-of-state of a disordered system of shape anisotropic patchy particles

ABSTRACT We present a new two dimensional model for elliptic (i.e. shape anisotropic) patchy colloids, where the impenetrable core of the particles is decorated on its (co-)vertices by Kern-Frenkel type of patches. Using (i) well-documented criteria for the overlap of the undecorated ellipses and (ii) proposing new criteria that give evidence if the patchy regions of two particles interact we perform extensive Monte Carlo simulations in the NPT ensemble. Considering elliptic particles of aspect ratios , and 6 with two patches located at the co-vertices and choosing representative values for the temperature we study on a semi-quantitative level the emerging disordered phases in terms of snapshots and radial distribution functions and present results for the equation-of-state.

Ventilation and heat transfer in a symmetrically ventilated salient pole synchronous machine

The results of a continuing effort to broaden understanding of heat transfer and ventilation in large synchronous salient pole electrical machines are presented. Heat transfer coefficients measured on an experimental four pole rotor for selected operational parameters are given and compared to computational fluid dynamics (CFD) predictions. The experimental programme was carried out on an hydraulically smooth rotor and corresponding heat transfer coefficients measured for the purpose of CFD validation are presented. The effects of surface roughness on the predicted values of heat transfer coefficients are then considered. Particular attention is given to the field coil faces where "strip-on-edge" windings are extended to give a ribbed surface. A method using an equivalent roughness, to account for the enhanced heat transfer, without increasing demands for mesh density is explained. The data presented demonstrate clearly the link between the flow field and the heat transfer coefficient. The potential use of CFD as a design tool to examine the effects of operating parameters and geometric modifications on heat transfer is illustrated.
