description: The implicit values of nutrient and nonnutrient characteristics of breakfast cereal were estimated using the 1987-88 household portion of the USDA's Nationwide Food Consumption Survey data. The effects of sociodemographic variables on cereal characteristic values were also estimated. The conceptual framework of the hedonic price model, used for food products, has traditionally focused on the nutritional characteristics of these products. This framework was extended to incorporate nonnutritional characteristics. Findings indicate that consumers' sociodemographic characteristics significantly affect the implicit values of both nutritional and nonnutritional cereal characteristics. Results generally met with prior expectations.

description: We present a study of the production of K_s^0 and Lambda^0 in inelastic pbar-p collisions at sqrt(s)= 1800 and 630 GeV using data collected by the CDF experiment at the Fermilab Tevatron. Analyses of K_s^0 and Lambda^0 multiplicity and transverse momentum distributions, as well as of the dependencies of the average number and of K_s^0 and Lambda^0 on charged particle multiplicity are reported. Systematic comparisons are performed for the full sample of inelastic collisions, and for the low and high momentum transfer subsamples, at the two energies. The p_T distributions extend above 8 GeV/c, showing a higher than previous measurements. The dependence of the mean K_s^0(Lambda^0) p_T on the charged particle multiplicity for the three samples shows a behavior analogous to that of charged primary tracks.

description: We construct the 4-dimensional ${\cal N}=\frac12$ and ${\cal N}=1$ inhomogeneously mass-deformed super Yang-Mills theories from the ${\cal N} =1^*$ and ${\cal N} =2^*$ theories, respectively, and analyse their supersymmetric vacua. The inhomogeneity is attributed to the dependence of background fluxes in the type IIB supergravity on a single spatial coordinate. This gives rise to inhomogeneous mass functions in the ${\cal N} =4$ super Yang-Mills theory which describes the dynamics of D3-branes. The Killing spinor equations for those inhomogeneous theories lead to the supersymmetric vacuum equation and a boundary condition. We investigate two types of solutions in the $ {\cal N}=\frac12$ theory, corresponding to the cases of asymptotically constant mass functions and periodic mass functions. For the former case, the boundary condition gives a relation between the parameters of two possibly distinct vacua at the asymptotic boundaries. Brane interpretations for corresponding vacuum solutions in type IIB supergravity are also discussed. For the latter case, we obtain explicit forms of the periodic vacuum solutions.

description: We study long polymer chains in a poor solvent, confined to the space between two parallel hard walls. The walls are energetically neutral and pose only a geometric constraint which changes the properties of the coil-globule (or "$θ$-") transition. We find that the $θ$ temperature increases monotonically with the width $D$ between the walls, in contrast to recent claims in the literature. Put in a wider context, the problem can be seen as a dimensional cross over in a tricritical point of a $ϕ^4$ model. We roughly verify the main scaling properties expected for such a phenomenon, but we find also somewhat unexpected very long transients before the asymptotic scaling regions are reached. In particular, instead of the expected scaling $R\sim N^{4/7}$ exactly at the ($D$-dependent) theta point we found that $R$ increases less fast than $N^{1/2}$, even for extremely long chains.

description: The largest portion of dairy and milk checkoff funds is spent on generic fluid milk advertising. These funds are distributed among four distinct media outlets-television, radio, print, and outdoor. Spending too little on one media outlet or too much on another constitutes a missed opportunity to garner higher returns. Using 1984-93 data, this study compares historical advertising expenditures in each media outlet to the advertising expenditure decision of an optimal control model. Results show profits would have increased if funds had been reallocated from television to radio, print, and outdoor media outlets.

description: Asteroids and comets (planetesimals) are created in gas- and dust-rich protoplanetary discs. The presence of these planetesimals around main-sequence stars is usually inferred from the detection of excess continuum emission at infrared wavelengths from dust grains produced by destructive processes within these discs. Modelling of the disc structure and dust grain properties for those discs is often hindered by the absence of any meaningful constraint on the location and spatial extent of the disc. Multi-wavelength, spatially resolved imaging is thus invaluable in refining the interpretation of these systems. Observations of HD 48682 at far-infrared (Spitzer,Herschel) and sub-millimetre (JCMT, SMA) wavelengths indicated the presence of an extended, cold debris disc with a blackbody temperature of 57.9 +\- 0.7 K. Here, we combined these data to perform a comprehensive study of the disc architecture and its implications for the dust grain properties. The deconvolved images revealed a cold debris belt, verified by combining a 3D radiative transfer dust continuum model with image analysis to replicate thestructure using a single, axisymmetric annulus. A Markov chain Monte Carlo analysis calculated the maximum likelihood of HD 48682's disc radius (Rdisc = 89 +17 -20 au), fractional width(DeltaRdisc = 0.41 +0.27 -0.20), position angle (theta = 66.3 +4.5 -4.9 degrees), and inclination (phi = 112.5 +4.2 -4.2 degrees). HD 48682 has been revealed to host a collisionally active, broad disc whose emission is dominated by small dust grains, smin approx. 0.6 microns, and a size distribution exponent of 3.60 +\- 0.02.

description: Oblast od oko 400 kvadratnih kilometara između današnje pozicije Dunava i starih i novog toka Tamiša u blizini Beograda je do sredine prošlog veka bila mozaik močvara i suvog terena koji je često plavljen. Pre nekoliko decenija, rekognosciranja ovog predela su dokumentovala postojanje tragova oko tridesetak lokaliteta razbacanih po celom području, iz različitih praistorijskih i istorijskih perioda. Ovo je ukazalo da je uprkos čestom plavljenju, ova oblast bila atraktivna za ljudsku upotrebu, a moguće i naseljavanje i to hiljadama godina pre savremenih drenaža terena.
 U proteklih nekoliko godina je sprovedena multidisciplinarna studija sa ciljem evaluacije potencijala ovog predela kao mesta trajnog naseljavanja. U prvoj fazi istraživanja je obavljeno rekognociranje, ispitivanje satelitskih i aerosnimaka, geomagnetna snimanja i geoarheološka bušenja. Ovi rezultati su poslužili za drugu fazu terenskih istraživanja koja su uključivala iskopavanje sondi, prikupljanje materijala i analizu arheobotaničkih i zooarheoloških nalaza. Na ovaj način, došlo se do saznanja o nastanjivanju ovog predela u prošlosti, u hidrološki bogatom i dinamičnom okruženju.

description: Wireless Sensor nodes connect the physical world to the digital world using smart, tiny and self configured stand alone devices. These small devices offer pack of brilliant opportunities to the digital world by capturing and revealing real time events which later used as data cloud in numerous applications. With impressive improvements in protocols, node level programming, simulation platforms and middleware developments sensor nodes have become promising options in the development of smart cities, gas and chemical industry, precision agriculture etc. However, these industrial application demands more lifetime and faster-secure data transmissions. In many applications it is recorded that with increase in network size LEACH routing protocol functioning degenerate. Further, designing of a promising routing protocol that can maintain less energy consumption during data gathering and propagation leads to use of variety of approaches. This work is based on the abstraction of equal distribution of energy among nodes with scalability. Experimental results show commendable improvement in network lifespan with residual energy of nodes to last for longer period. Throughput is also monitored considering scalability.

description: In this paper, the fuzzy multi-objective reliability redundancy allocation problem (FMORRAP) is proposed, which maximizes the system reliability while simultaneously minimizing the system cost under the type 2 fuzzy uncertainty. In the proposed formulation, the higher order uncertainties (such as parametric, manufacturing, environmental, and designers uncertainty) associated with the system are modeled with interval type 2 fuzzy sets (IT2 FS). The footprint of uncertainty of the interval type 2 membership functions (IT2 MFs) accommodates these uncertainties by capturing the multiple opinions from several system experts. We consider IT2 MFs to represent the subsystem reliability and cost, which are to be further aggregated using extension principle to evaluate the total system reliability and cost according to their configurations, i.e., series parallel and parallel series. We proposed a particle swarm optimization (PSO) based novel solution approach to solve the FMORRAP. To demonstrate the applicability of two formulations, namely, series parallel FMORRAP and parallel series FMORRAP, we performed experimental simulations on various numerical data sets. The decision makers/system experts assign different importance to the objectives (system reliability and cost), and these preferences are represented by sets of weights. The optimal results are obtained from our solution approach, and the Pareto optimal front is established using these different weight sets. The genetic algorithm (GA) was implemented to compare the results obtained from our proposed solution approach. A statistical analysis was conducted between PSO and GA, and it was found that the PSO based Pareto solution outperforms the GA.

description: Using first-principles transport calculations, we predict that the anisotropic magnetoresistance (AMR) of single-crystal Co$_x$Fe$_{1-x}$ alloys is strongly dependent on the current orientation and alloy concentration. An intrinsic mechanism for AMR is found to arise from the band crossing due to magnetization-dependent symmetry protection. These special $k$-points can be shifted towards or away from the Fermi energy by varying the alloy composition and hence the exchange splitting, thus allowing AMR tunability. The prediction is confirmed by delicate transport measurements, which further reveal a reciprocal relationship of the longitudinal and transverse resistivities along different crystal axes.

description: The Japanese spineless cuttlefish (Sepiella japonica) is an important economic species and model animal. Many studies suggested that microRNAs (miRNAs) play an important regulatory role in the embryonic development of this species. However, comparative miRNA profiles during embryogenesis of cuttlefish have not been reported before. Therefore, in this study, miRNA profiles were obtained from embryos of S. japonica from eye primordium formation to larval growing stage by miRNA sequencing. A total of 1528 known miRNAs and 203 novel miRNAs were identified during different development stages. Among which, 62 differentially expressed miRNAs among different development stages were identified. GO analysis indicated that the potential target genes for these differentially expressed miRNAs were involved in many GO terms including intracellular membrane-bounded organelle, cell morphogenesis, regulation of developmental process, etc. In addition, miRNA-mRNA network analysis indicated that many of target genes of these differentially expressed miRNAs were involved in integral component of membrane. In conclusion, our work provided a global view of miRNA expression profiles during embryonic development of S. japonica.

description: This study evaluates agricultural forecasting accuracy in an analysis of responses to the Annual Outlook Survey conducted by the American Agricultural Economics Association from 1983 through 1995. Representative extension and composite, production, and price forecasts for several commodities are constructed from the survey data. These forecasts are compared to each other and to U.S. Department of Agriculture (USDA) and futures-based forecasts. Relationships between forecast features and accuracy are examined. Generally, extension forecasts are more accurate than USDA forecasts for livestock series, but not more accurate for crops. Composite forecasts are often more accurate than either extension or USDA forecasts.

description: Anthony (Tony) Laughton was an oceanographer who promoted the science of oceanograpy in Britain. Focusing on the shape of the seafloor, his work included underwater photography, ocean drilling, long-range side-scan sonar and scientific charting of the ocean floor. Following undergraduate studies at King's College, Cambridge, he joined Maurice Hill (FRS 1962) at the Cambridge Department of Geodesy and Geophysics, beginning a career in marine geophysics. Following his PhD, he spent a year at Lamont Geological Observatory, USA, where he met many leading US workers, and became interested in deep-seafloor photography and bathymetric mapping. Returning to the UK, he joined the National Institute of Oceanography (Institute of Oceanographic Sciences from 1973) at Wormley, Surrey, and became director in 1978. He developed the first UK seafloor camera, was an enthusiastic supporter and user of the revolutionary Precision Echo Sounder and later of the GLORIA long-range side-scan sonar. He played a significant part in the International Indian Ocean Expedition, subsequently developing a new understanding of the Gulf of Aden. A consummate committee man, he had a vital role in reviving the General Bathymetric Chart of the Oceans and promoted UK involvement in the international Deep-Sea Drilling Project. He was an accomplished amateur musician (playing French horn), small-boat sailor and handyman.

Moving on : the post-treatment experience of women and families with breast cancer
Creators: name: Emery, Christine Ann
Publisher: name: University of British Columbia
Year: 2009

description: The initial period of time after treatment for cancer ends has been described as one of ambivalence and limbo (Halvorson-Boyd & Hunter, 1995; Hurt, McQuellon and Barrett, 1994) - yet few researchers have specifically studied the immediate post-treatment period, particularly from a family perspective. The purpose of this study was to explore and describe what life is like for women and their families in the first six months following completion of adjuvant treatment for breast cancer. Interpretive description was the qualitative method chosen for the study. In-depth interviews were conducted with eleven family dyads (the woman diagnosed with breast cancer and a family member of her choosing) who were between one and six months posttreatment. The data was analyzed using an inductive approach. The initial post-treatment period was revealed as a time of transition when families move past the cancer into normal life - a new normal that must take into account the cancer experience. "Moving On" was identified as an appropriate overall descriptor of the experience. Three subthemes - making sense of the experience, managing the threat of recurrence, and rejoining the world of normal - describe the concerns of the women and families and their strategies for managing the post-treatment experience. Six families had a different and more challenging experience post-treatment than the other five families. A variety of factors related to family, treatment, and interactions with health care providers that appeared to contribute to the variations in Moving On are also discussed. By shedding light on how the first six months following treatment for breast cancer is manifested in family life, this study has implications for health care professionals working with women with breast cancer and their families.

description: Recovering the 3D shape of an object from single or multiple images with deep neural networks has been attracting increasing attention in the past few years. Mainstream works (e.g. 3D-R2N2) use recurrent neural networks (RNNs) to sequentially fuse feature maps of input images. However, RNN-based approaches are unable to produce consistent reconstruction results when given the same input images with different orders. Moreover, RNNs may forget important features from early input images due to long-term memory loss. To address these issues, we propose a novel framework for single-view and multi-view 3D object reconstruction, named Pix2Vox++. By using a well-designed encoder-decoder, it generates a coarse 3D volume from each input image. A multi-scale context-aware fusion module is then introduced to adaptively select high-quality reconstructions for different parts from all coarse 3D volumes to obtain a fused 3D volume. To further correct the wrongly recovered parts in the fused 3D volume, a refiner is adopted to generate the final output. Experimental results on the ShapeNet, Pix3D, and Things3D benchmarks show that Pix2Vox++ performs favorably against state-of-the-art methods in terms of both accuracy and efficiency.

Using Andragogy to Teach Pedagogy: Expecting Heutagogy – Using Against-the-Grain Teaching Practices for Desired Outcomes
Creators: name: Smith, M.
Publisher: name: The School of Education and Communities, University of East London
Year: 2017

description: This position paper discusses a dichotomy that lies at the heart of Initial Teacher Education – that many of those involved in preservice teacher education identify themselves as social constructivists and espouse personal pedagogical practices that lean towards learner-centrism rather than didactic praxes but are obliged to teach in a rather more transmissionist style due to the exigencies and contingencies of the courses they run. Teaching adults is different to teaching children, but where we are teaching adults to teach children, how do we plot a course between the two extremes? The conclusions are that allowing adults to learn for themselves leads to both more effective learning and better teaching, but that within the parameters of the preservice teacher education courses run at higher education institutions in the UK, teacher educators often have to sacrifice their constructivist principles and anticipate that trainees will fill in the gaps for themselves.

description: 5G is a new paradigm that brings new technologies to overcome the challenges of the next-generation wireless mobile network. Also, 5G is expected to supply fastest, most reliable network access to support huge data traffic and massively connected nodes with low latency and high throughput. There are different new technologies that are emerging to tackle requirements of the future wireless mobile network, such as Network Function Virtualization (NFV), Software Defined Networking (SDN) and cloud computing. The heterogeneous environment of 5G will cause frequent handoff in small cells where users join and leave frequently. Therefore, in this paper, the focus is on secure and seamless handover mechanism to supply strong, quick and mutual authentication. And, a careful attention is needed to security challenges, therefore, potential pitfalls can be avoided. We begin by explaining emerging technologies for the 5G mobile network. Then, the architecture of SDN is briefly described. Finally, this article presents a fast and efficient vertical handover authentication for next-generation wireless mobile communication - 5G – based on SDN architecture.

description: Extension marketing economists commit substantial resources to outlook and market analysis. Producers demand this information and use it to make production and marketing decisions. This study analyzes responses to a marketing survey of producers and extension marketing economists to discern similarities and differences in their perceptions regarding market timing, futures market efficiency, and risk management. Producer and extension perceptions are consistent with regard to several marketing issues, although they are not always consistent with published research results. Both producers and extension economists disagree that producers will receive a lower average price by forwarding contracting, and many do not believe hedging reduces risk and lowers expected return. Extension marketing economists rate risk reduction as a less important goal of marketing strategies than do producers.

description: Fence-in laws in most states require ranchers to pay for fences to keep their livestock from trespassing onto others' property. Some states, or jurisdictions within states, have a fence-out rule that requires ranchers' neighbors to pay for fences to keep livestock out. Both rules are Pareto optimal. Using a potential Pareto criterion, we show that a preference for fence-out in some areas may end as conditions change, such as increased nonranching land uses. Changed conditions may have legal consequences. Specific fence-out and fence cost-sharing provisions may be potentially Pareto inefficient and may be challenged for being unconstitutional under the due process clause.

description: The value of maintaining a minimum streamflow objective on average is lessened when there is considerable dispersion around the average. An integrated economic and hydrology model is presented which provides water policy planners with a way to accurately measure both the economic cost and hydrologic consequences of maintaining a minimum streamflow level in an irrigated river basin at alternative probabilities of maintaining the target flow level. Water markets for streamflow augmentation are shown to be the most cost-effective policy in the study area.

description: Agricultural trade liberalization among the three North American Free Trade Agreement (NAFTA) signatories is modeled using a political preference function. The model distinguishes among Canada, Mexico, the United States, and a politically passive rest of the world. Through the use of intracountry compensation, the analysis shows that, from an agricultural perspective, economic integration is in the best interest of the group as a whole, although not in the best interest of individual countries. More specifically, of the agricultural production sectors, Canadian dairy, Mexican corn, and U.S. beef producers suffer the greatest losses from the formation of North American customs union.

description: The $Golomb$ $space$ (resp. the $Kirch$ $space$) is the set $\mathbb N$ of positive integers endowed with the topology generated by the base consisting of arithmetic progressions $a+b\mathbb N_0=\{a+bn:n\ge 0\}$ where $a\in\mathbb N$ and $b$ is a (square-free) number, coprime with $a$. It is known that the Golomb space (resp. the Kirch space) is connected (and locally connected). By a recent result of Banakh, Spirito and Turek, the Golomb space has trivial homeomorphism group and hence is topologically rigid. In this paper we prove the topological rigidity of the Kirch space.

description: A technique for point-contact spectroscopy, based on an electro-mechanical mechanism for the contact formation, has been developed. It is designed to be used in both $^4$He and $^3$He cryostats. The performance has been demonstrated by conductance measurements on various kinds of superconductors, including the conventional superconductor Nb, the two-band superconductor MgB$_2$, and the heavy-fermion superconductor CeCoIn$_5$.

description: The evolution of buoyancy-driven homogeneous variable-density turbulence (HVDT) at Atwood numbers up to 0.75 and large Reynolds numbers is studied by using high-resolution Direct Numerical Simulations. To help understand the highly non-equilibrium nature of buoyancy-driven HVDT, the flow evolution is divided into four different regimes based on the behavior of turbulent kinetic energy derivatives. The results show that each regime has a unique type of dependency on both Atwood and Reynolds numbers. It is found that the local statistics of the flow based on the flow composition are more sensitive to Atwood and Reynolds numbers compared to those based on the entire flow. It is also observed that at higher Atwood numbers, different flow features reach their asymptotic Reynolds number behavior at different times. The energy spectrum defined based on the Favre fluctuations momentum has less large scale contamination from viscous effects for variable density flows with constant properties, compared to other forms used previously. The evolution of the energy spectrum highlights distinct dynamical features of the four flow regimes. Thus, the slope of the energy spectrum at intermediate to large scales evolves from -7/3 to -1, as a function of the production to dissipation ratio. The classical Kolmogorov spectrum emerges at intermediate to high scales at the highest Reynolds numbers examined, after the turbulence starts to decay. Finally, the similarities and differences between buoyancy-driven HVDT and the more conventional stationary turbulence are discussed and new strategies and tools for analysis are proposed.
Towards Solving the Recruitment Crisis in Maths Teaching: The Role of Subject Knowledge Enhancement Courses
Creators: name: Bell, C.
Publisher: name: The School of Education and Communities, University of East London
Year: 2017

description: Subject Knowledge Enhancement (SKE) courses aim to provide sufficient subject knowledge in ‘shortage subject’ areas, such as mathematics and science, to enable those who attend them to then undertake Initial Teacher Training and to go on to become teachers in secondary schools. This paper examines the learning experience of a group of SKE participants, and assesses whether this added significantly to their subject knowledge and helped prepare them for work in the classroom, comparing this outcome with conventional teacher trainees who had not undertaken such a course.

description: The expectation of explaining cosmological observations without requiring new energy sources is forsooth worthy of investigation. In this letter, a new kind of Cardassian models, called exponential Cardassian models, for the late-time universe are investigated in the context of the spatially flat FRW universe scenario. We fit the exponential Cardassian models to current type Ia supernovae data and find they are consistent with the observations. Furthermore, we point out that the equation-of-state parameter for the effective dark fluid component in exponential Cardassian models can naturally cross the cosmological constant divide $w=-1$ that observations favor mildly without introducing exotic material that destroy the weak energy condition.

description: In traditional SaaS enterprise applications, microservices are an essential ingredient to deploy machine learning (ML) models successfully. In general, microservices result in efficiencies in software service design, development, and delivery. As they become ubiquitous in the redesign of monolithic software, with the addition of machine learning, the traditional applications are also becoming increasingly intelligent. Here, we propose a portable ML microservice framework Minerva (microservices container for applied ML) as an efficient way to modularize and deploy intelligent microservices in traditional legacy SaaS applications suite, especially in the enterprise domain. We identify and discuss the needs, challenges and architecture to incorporate ML microservices in such applications. Minervas design for optimal integration with legacy applications using microservices architecture leveraging lightweight infrastructure accelerates deploying ML models in such applications.
Two-dimensional structure of thin transonic discs: theory and observational manifestations

description: We study the two-dimensional structure of thin transonic accretion discs in the vicinity of black holes. We use the hydrodynamical version of the Grad-Shafranov equation and focus on the region inside the marginally stable orbit. We show that all components of the dynamical force in the disc become significant near the sonic surface and especially important in the supersonic region. Under certain conditions, the disc structure is shown to be far from radial, and we review the affected disc properties, in particular the role of the critical condition at the sonic surface: it determines neither the accretion rate nor the angular momentum in the accretion disc. Finally, we present a simple model explaining quasi-periodical oscillations that have been observed in the infrared and X-ray radiation of the Galactic Centre.

Effects of forest loss and fragmentation with urbanization on bird communities in Vancouver
Creators: name: Er, Kenneth Boon Hwee
Publisher: name: University of British Columbia
Year: 2009

description: Habitat modification with urbanization encompasses the processes of habitat loss and fragmentation. In line with the urban wildlife management goal of maximizing species diversity at the landscape and within-patch scales, it is important to understand the effects of these two processes on wildlife communities. Using Vancouver in British Columbia as the study area, I tested the hypotheses that (1) loss in forest area in the landscape with urbanization results in bird extirpations as expressed by the species-area function; and (2) fragmentation of the remaining forest into fragments with urbanization results in large fragments having greater bird species richness and densities than small fragments because large fragments contain a greater diversity and/or abundance of habitat resources. Prior to European settlement in 1859, Vancouver was covered completely by coastal western hemlock forest. By estimating the area of forest loss in Vancouver since 1859 and reviewing the conservation status of birds in Vancouver, I show that the observed number of bird extirpations due to forest loss matches that predicted by the species-area function for bird species closely associated with lowland coastal temperate forests and restricted in their geographic distribution in British Columbia. Using bird and habitat data collected in 14 forest fragments in Vancouver and lower West Vancouver, I show that large fragments support higher bird species richness and density than small fragments in spring, summer and fall. This could be attributed to large fragments containing a greater diversity and/or abundance of habitat resources, especially tree species diversity and abundance of decaying standing material. However, this mechanism is unable to satisfactorily explain all the patterns across seasons. I also found that bird species richness and density were responding to habitat resources that remained constant with area. Hence, there is a possibility that birds may not even select for large fragments despite the greater diversity and/or abundance of habitat resources, if resources that are independent of area are changed dramatically.

description: In the framework of Granular Computing (GC), Interval type 2 Fuzzy Sets (IT2 FSs) play a prominent role by facilitating a better representation of uncertain linguistic information. Perceptual Computing (Per C), a well known computing with words (CWW) approach, and its various applications have nicely exploited this advantage. This paper reports a novel Per C based approach for student strategy evaluation. Examinations are generally oriented to test the subject knowledge of students. The number of questions that they are able to solve accurately judges success rates of students in the examinations. However, we feel that not only the solutions of questions, but also the strategy adopted for finding those solutions are equally important. More marks should be awarded to a student, who solves a question with a better strategy compared to a student, whose strategy is relatively not that good. Furthermore, the students strategy can be taken as a measure of his or her learning outcome as perceived by a faculty member. This can help to identify students, whose learning outcomes are not good, and, thus, can be provided with any relevant help, for improvement. The main contribution of this paper is to illustrate the use of CWW for student strategy evaluation and present a comparison of the recommendations generated by different CWW approaches. CWW provides us with two major advantages. First, it generates a numeric score for the overall evaluation of strategy adopted by a student in the examination. This enables comparison and ranking of the students based on their performances. Second, a linguistic evaluation describing the student strategy is also obtained from the system. Both these numeric score and linguistic recommendation are together used to assess the quality of a students strategy. We found that Per-C generates unique recommendations in all cases and outperforms other CWW approaches.

description: We propose a double-cavity set-up capable of generating a stationary entangled state of two movable mirrors at cryogenic temperatures. The scheme is based on the optimal transfer of squeezing of input optical fields to mechanical vibrational modes of the mirrors, realized by the radiation pressure of the intracavity light. We show that the presence of macroscopic entanglement can be demonstrated by an appropriate read out of the output light of the two cavities.
