description: This study undertaken in the Peechi Command Area of Thrissur district in the Kerala state, has examined the resource productivity and allocative as well as the technical efficiency of paddy production. The study has used the primary data collected from 71 rice farmers of the command area using the stratified random sampling. The cost of cultivation of paddy in the command area has been found as Rs 21603/ha, resulting in a BC ratio of 1.34. The elasticity coefficients for chemical fertilizers, farmyard manure and human labour have been observed significant and positive. The allocative efficiency has indicated that marginal return per one rupee increase under these heads would be Rs 2.83, Rs 1.57 and Rs 1.17, respectively. The average technical efficiency of the paddy farmers in the command area has been found as 66.8 per cent. Education of the farmer and supplementary irrigation provided during the water-stress days have been identified as the factors which could enhance the technical efficiency. The study has called for an equitable distribution of canal water and enhanced extension services for resource management in the area.

description: Irrigation sector investments in Kerala have been mounting since Independence, but the financial performance of these investments has been far from satisfactory. In an era of growing divergence in water supply and demand, the emergence of water markets is imminent. This calls for a realistic pricing strategy for water use, whether in agriculture or other sectors. The canal water though targeted at the agriculture sector, is often put to non-irrigation uses. This paper has discussed a method to quantify the non-irrigation uses of canal water and has assessed the value of the same, based on a sample study in Peechi Irrigation Command Area in Thrissur district of Kerala, India . The value has been assessed for the water used directly for irrigation from the canal system, water used through the recharge facility from the canal and non-irrigation uses (domestic).

description: There has been a growing realization for rehabilitation and restoration of irrigation tanks with farmers’ participation. The study has presented the costs and benefits of tank rehabilitation and financial feasibility of investment in tank rehabilitation. The total annual income has been found higher in the rehabilitated tanks than the non-rehabilitated tanks and amongst the rehabilitated tanks, panchayat tanks with community well has depicted the highest annual income. The investment analysis has revealed the net present worth to be positive, the B-C ratio to be more than 1.5 and the internal rate of return to be more than the opportunity cost of capital. This shows that all the three investments in tank rehabilitation are economically viable. The study has suggested that rehabilitation work should be undertaken in all the non-rehabilitated tanks also. Besides, efforts should be made to provide supplemental irrigation to crops and to improve the PWD tank management regime.

description: In this article, we address the question of regional development by arguing that a new approach motivates government policies at this level. We present the case study of a cooperative representing a strategy of a community trying to better control its socio-economic destiny. By taking charge of its destiny and influencing the rules that will preside over its socio-economic development, the community (including employees) is thus able to influence the orientation of its development according to the larger needs of the community. In other words, an opportunity is created to define socioeconomic development according not only to economic demands, but also to cultural and social ones within the community. Many situations present themselves on the continuum that goes from strictly private entrepreneurship that first and foremost satisfies the needs of the owners, to collective entrepreneurship geared towards serving the association of workers and the community’s interests. Our case study demonstrates the role played by the mobilization of certain social actors in the community, in the creation of a collective enterprise. It also shows how the conditions of this entrepreneurial effort may prevent the redefinition of economic rules that would not easily allow a development based, at least in part, on the larger demands of the community.

description: In addition to the conventional auction method of cattle marketing, some alternative marketing arrangements include sale by private treaty, video auction, retained ownership, and use of strategic alliances. This study finds that 91% of Louisiana producers use conventional auctions, while 39% use other types of marketing arrangements. The most heavily used alternative marketing arrangement is private treaty, at 26%. Those producers using alternative marketing arrangements tend to be larger, have heavier weaning weights, have more diverse farming operations, be younger, have greater contact with their county extension agents, and depend less on income from off-farm sources.

description: To understand how image compression actually occurs, the numerical method of interpolation must be explored. Interpolation works by using data to estimate values at unknown points. Similar to having a data set of values and wanting to determine the corresponding function that describes these values in Numerical Computer. Real world application include image resizing and image compression. Here, the Haar transform coding technique is used to illustrate how such an interpolation is used to compress images.

description: A choice-based conjoint experiment was used to examine consumer willingness to pay for a farm-raised pre-cooked roast beef product. Consumers were contacted in a grocery store and provided a sample of the pre-cooked product. Findings indicate there is a small, but statistically significant willingness-to-pay premium for the farm-raised product, suggesting that some product differentiation may result in higher prices for these products. The study outlines an approach to marketing research.

description: Under the direction of the Agricultural Risk Protection Act of 2000, the U.S. Congress proposed a crop insurance program for the Bristol Bay, Alaska, commercial salmon fishery. This study examines the feasibility of extending crop insurance to this commercial fishery. The specific focus of this analysis is on differences between this commercial capture fishery and agricultural enterprises in the context of property rights and producer control. Findings show that differences between this commercial fishery and agricultural enterprises would require substantial modifications to existing crop insurance programs. Furthermore, it is recommended that the consideration of extending crop insurance be delayed until this fishery is rationalized.

description: The international and local Nicaraguan media have widely reported on the “coffee crisis” in Latin America and there is substantial evidence that there has been a downturn and that this has been more severe in the coffee-growing regions. Using household panel data from a randomized community-based intervention carried out in both coffee- and noncoffee-growing areas, I examine the role of a conditional cash transfer program, the Red de Protección Social (RPS), during this downturn. While not designed as a traditional safety net program in the sense of reacting or adjusting to crises or shocks, RPS has performed like one, with larger estimated program effects for those who were more severely affected by the downturn. For example, it protected households against declines in per capita expenditures and, while not significantly depressing labor supply relative to before the program, muted additional labor supply for beneficiaries in coffee-growing areas, relative to their counterparts without the program. Beneficiaries who participated in the coffee industry as laborers before the program were more likely to have exited the coffee industry, whereas those who participated as producers were less likely to have exited. The findings are consistent with the existence of credit constraints inhibiting such transitions in the absence of the program. Overall, then, RPS appears to be playing an important part in the risk-coping strategies of households.

description: Fahr's syndrome is a rare, genetically dominant, inherited, neurological disorder characterised by abnormal depositsof calcium in areas of the brain that control movement, including the basal ganglia and the cerebral cortex.Symptoms of the disorder may include deterioration of motor functions, dementia, seizures, headache, blurring ofvision, spasticity (stiffness of limbs) and athetosis (involuntary, writhing movements). The most common site ofcalcification is the globus pallidus. However additional areas of calcification are putamen, caudate nucleus, internalcapsule, dentate nucleus, thalamus, cerebellum and cerebral white matter. We are presenting a case of a 30 year oldmale, who complained of stiffening of upper limbs and blurring of vision followed by giddiness which wasassociated with slowness of movements. His CT scan revealed a symmetrical large area of calcification over thebasal ganglia. Secondary causes of this disease were ruled out to make the clinical diagnosis of BilateralStriopallidodentate Calcinosis, [BSPDC] which is otherwise called as the Fahr's syndrome.

description: We measure the dipion mass spectrum in X(3872)--> J/Psi Pi+ Pi- decays using 360 pb-1 of pbar-p collisions at 1.96 TeV collected with the CDF II detector. The spectrum is fit with predictions for odd C-parity (3S1, 1P1, and 3DJ) charmonia decaying to J/Psi Pi+ Pi-, as well as even C-parity states in which the pions are from Rho0 decay. The latter case also encompasses exotic interpretations, such as a D0-D*0Bar molecule. Only the 3S1 and J/Psi Rho hypotheses are compatible with our data. Since 3S1 is untenable on other grounds, decay via J/Psi Rho is favored, which implies C=+1 for the X(3872). Models for different J/Psi-Rho angular momenta L are considered. Flexibility in the models, especially the introduction of Rho-Omega interference, enable good descriptions of our data for both L=0 and 1.

Modeling and compensation of machine tool volumetric errors for virtual CNC environment
Creators: name: Bal, Evren
Publisher: name: University of British Columbia
Year: 2009

description: Machine tools produce positioning errors due to thermal and structural deformations of the structural elements, geometric errors due to inaccuracies in the manufacturing and assembly of their components, and computer numerical control errors caused by the bandwidth of their servo drives. This thesis presents the measurement, modeling and compensation of geometric errors of three axis machine tools in order to simulate and improve their volumetric accuracy in virtual environment. The geometric accuracy of each axis is measured using a laser interferometer. The displacement, pitch, yaw and backlash errors of each axis element are measured and mapped to the machine coordinates using rigid body kinematic transformations of the system. The identified errors are curve fitted to the position of each drive in the machine coordinates. The algorithm allows prediction of relative positioning error between the tool and workpiece within the working volume of the machine tool, or pre-compensates the errors by adding the estimated positioning errors to Numerical Control (NC) program in Virtual Environment before the machining takes place. The prediction and compensation of geometric errors are experimentally demonstrated on a three axis, vertical CNC machining center. Standard ISO geometric profiles, a circle and a diamond, slot milled on the machine. The machined profiles are measured using a coordinate measuring machine, and the lengths and offsets from the command profiles are estimated from the measurements. The measurement results and the predicted geometric errors are compared. The contributions of CNC and tool deflections to the total errors are estimated, and the remaining errors are correlated to geometric errors of the machine tool. Although, it was not possible to account all the machine tool errors, the proposed prediction and correction method in virtual environment improved the compensation of geometric errors significantly. The overall model is integrated to UBC Manufacturing Automation Laboratory's Virtual CNC system for use in industry.

These are constructed using a new `Legendrian tangle replacement' technique. This technique is then used to show that the phenomenon of multiple Chekanov polynomials is in fact quite common. Finally, building on unpublished work of Yufa and Branson, a tabulation is given of Legendrian fronts, along with their Chekanov polynomials, representing maximal Thurston-Bennequin Legendrian knots for each knot type of nine or fewer crossings. These knots are paired so that the front for the mirror of any knot is obtained in a standard way by rotating the front for the knot.

description: A new scheme of state classification is proposed and applied to analyze masses of the heavy baryons $Ω_{Q}$, $Σ_{Q}$ and $Ξ_{Q}^{\prime}$ in P-waves. The results confirm all excited $Ω_{c}$ and $Ω_{b}$ baryons reported recently by LHCb to be bound states of a P-wave $ss$-diquark and a respective charm or bottom quark, and thereby predict Regge trajectories for more excited $Ω_{c}$ and $Ω_{b}$ baryons. We suggest one excited {$J^{P}=5/2^{-}$} $Ω_{b}$ state to be unseen by LHCb around $6352$ MeV, and predict P-wave masses of all spin-partners of the odd-parity baryons $Σ_{c}(2800)/Ξ_{c}^{\prime}(2942)$ and $Σ_{b}(6097)$/$Ξ_{b}^{\prime }(6227)$. A computation is further given in a relativized potential quark models to explain matched values of spin couplings of all considered baryons, by which a scaling law for these spin couplings is discussed.

description: The “Cost of Basic Needs” (CBN) approach to drawing consumption-based poverty lines is widely applied and lays credible claim to being the best practice for estimating poverty measures. Unfortunately, a growing mass of evidence indicates that poverty estimates obtained under the CBN approach are often demonstrably utility inconsistent. Here, we introduce an information theoretic approach for estimating utility-consistent poverty lines. An example of the approach is provided for the case of Mozambique. The approach represents a powerful addition to the poverty analyst’s tool kit and enhances the attractiveness of the CBN approach for practical poverty measurement problems.

description: This paper empirically identifies social learning and neighborhood effects in schooling investments in a new technology regime. The estimates of learning-investment rule from farm household panel data at the onset of the Green Revolution in India, show that (1) agents learn about schooling returns from income realizations of their neighbors and (2) schooling distribution of the parents’ generation in a community has externalities to schooling investments in children that are consistent with social learning. Simulations show that variations in schooling distributions within and across communities generate through social learning substantial variations in child enrollment rate and average household income. The results suggest that imperfect information hinders investment in human capital.

We also give variations of the McShane-Bowditch identities to characters fixed by an Anosov element of $Γ$ with applications to closed hyperbolic three manifolds. Finally we give a definition of end invariants for SL(2,C) characters and give a partial classification of the set of end invariants of a character in ${\mathcal X}$.

description: Using data that enables us to distinguish between the different components of program participation (i.e., knowledge, application, and acceptance), we investigate the determinants of household behavior and program implementation in a social safety-net program that combines administrative and self-selection targeting methods. High undercoverage of eligible households primarily reflects lack of knowledge and binding budget constraints in poor areas. High leakage to ineligible households reflects the combination of their high levels of knowledge, application, and acceptance. Lowering undercoverage will require greater program awareness among the poor living in nonpoor areas and this is likely to come at the expense of substantial leakage to the nonpoor unless improvements are made to the verification process. Our results also suggest that in the presence of a budget constraint, the administrative selection process gives priority to the poorest households and those with children.

description: I present the theory and analysis behind the experiment by Fomalont and Kopeikin involving Jupiter and quasar J0842+1845 that purported to measure the speed of gravity. The computation of the v_J/c correction to the gravitational time delay difference relevant to the experiment is derived, where v_J is the speed of Jupiter as measured from Earth. Since the v_J/c corrections are too small to have been measured in the Jupiter/quasar experiment, it is impossible that the speed of gravity was extracted from the data, and I explain what when wrong with the data analysis. Finally, mistakes are shown in papers by Fomalont and Kopeikin intended to rebut my work and the work of others.

description: We present a color-magnitude diagram (CMD) of the globular cluster SKHB-312 in the Andromeda galaxy (M31), obtained with the Advanced Camera for Surveys on the Hubble Space Telescope. The cluster was included in deep observations taken to measure the star formation history of the M31 halo. Overcoming a very crowded field, our photometry of SKHB-312 reaches V ~ 30.5 mag, more than 1 mag below the main sequence turnoff. These are the first observations to allow a direct age estimate from the turnoff in an old M31 cluster. We analyze its CMD and luminosity function using a finely-spaced grid of isochrones that have been calibrated using observations of Galactic clusters taken with the same camera and filters. The luminosity difference between the subgiant and horizontal branches is ~0.2 mag smaller in SKHB-312 than in the Galactic clusters 47 Tuc and NGC 5927, implying SKHB-312 is 2-3 Gyr younger. A quantitative comparison to isochrones yields an age of 10 +2.5/-1 Gyr.

description: Typical living standards surveys can provide a wealth of information about welfare levels, poverty, and other household and individual characteristics. However, these estimates are necessarily at a high level of aggregation, because such surveys usually include only a few thousand households, with coarse spatial stratification. Larger databases, such as national censuses, provide sufficient observations for more disaggregated analysis, but typically collect very little socioeconomic information. This paper combines data from the 1996–97 Mozambique National Household Survey of Living Conditions with the 1997 National Population and Housing Census to generate small-area (subdistrict) estimates of welfare, poverty, and inequality, with the associated standard errors. These small-area estimates are then used to explore several dimensions of poverty and inequality in Mozambique, particularly with regard to geographical targeting of antipoverty efforts. Reliably identifying and targeting the poor can be administratively costly, especially in rural Africa, where low population density and weak administrative capacity are common. Geographical targeting, or targeting poor areas, is sometimes proposed as a feasible alternative to targeting poor people, and poverty maps may serve as a valuable tool in this regard. Unfortunately, the notion of poor areas might not always be especially useful, as appears to be the case in Mozambique. The poverty maps do not reveal a particularly strong spatial concentration of poverty; the differences in poverty levels between areas tend to be subtle. This pattern is also observed in the decomposition of small-area inequality estimates, which shows that only about 20 percent of consumption inequality is accounted for by inequality between districts or between administrative posts. The picture that emerges of the poor living alongside the nonpoor indicates that targeting poor areas is likely to result in leakage to the nonpoor in that area, and considerable under-coverage of the significant numbers of poor households in areas that are less poor.

description: Maize is a major staple food in Sub-Saharan Africa. Monthly maize prices in Tanzania are analyzed since the country is an important maize producer and exporter in East Africa. We analyze price transmission between the five most important urban regions of Tanzania between 2000 and 2008 which correspond to major maize production or consumption areas. We propose a novel method for the analysis. The semiparametric vector error-correction model allows the partial impact of the past deviations from price equilibria on current price changes to be potentially nonlinear. The nonparametric estimates of these partial influences suggest that they can be adequately modeled by linear functions.

description: There is evidence that some multi-person households may withhold income transfers, such as bonuses, gifts, and cash transfers, from other members of the household (Ashraf (2009); Vogler and Pahl, (1994)). In this paper, I show that the incentives to hide income under incomplete information regarding the quantity of resources available to the household differ for three different household resource management structures. I illustrate this with a simple two-stage game. In the first stage, one spouse receives a monetary transfer that is unobserved by her spouse, and she must decide whether to reveal or to hide it. In the second stage, spouses bargain over the allocation of resources between a household good and private expenditure. The three models differ in the resource allocation mechanism that takes place in second stage of the game: housekeeping allowance, independent management, and joint management. Results indicate that when one spouse receives a monetary transfer that is unobservable to her spouse, hiding is more likely to occur in households with a housekeeping allowance contract, compared to independent or joint management. In joint management households, however, a spouse may hide in equilibrium if the change in bargaining power associated with revealing the transfer is not significant enough to compensate for the loss in discretionary expenditure.
Transciptional regulation of human gonadotropin-releasing hormone (GnRH) and GnRH receptor genes
Creators: name: Cheng, Chi Keung
Publisher: name: University of British Columbia
Year: 2009

description: In addition to its pivotal role in controlling gonadotropin synthesis and secretion, mammalian gonadotropin-releasing hormone (termed GnRH-I) functions as an autocrine and/or paracrine factor in certain extrapituitary tissues, where expression of its receptor (GnRH-I receptor) has been demonstrated. Although our laboratory has previously addressed a number of issues regarding the transcriptional regulation of the human GnRH-I receptor gene, some aspects including tissue-specific and hormonal regulation of the gene expression remain unclear. In the present study, we have identified by stepwise deletion analysis a new upstream GnRH-I receptor promoter that is primarily used by ovarian granulosa-luteal (GL) cells. Site-directed mutagenesis indicated that the activity of this promoter was governed by a cooperative action among two CCAAT/enhancerbinding protein (C/EBP) and one GATA motifs. On the one hand, these data strengthen the notion that tissue-specific expression of the human GnRH-I receptor gene is mediated by differential promoter usage in various cell types. On the other hand, we have identified an evolutionarily conserved octamer sequence, which constitutively and ubiquitously suppresses the GnRH-I receptor promoter. Electrophoretic mobility shift assays (EMSAs) showed that the repressor binding to this element was the POU homeodomain transcription factor Oct-1. These findings thus uncover a novel role of Oct-1 in silencing GnRH-I receptor gene transcription. Furthermore, we have demonstrated that an activator protein-1 (AP-l)-like motif mediates 17β-estradiol (E2) repression of the GnRH-I receptor promoter via an estrogen receptor (ER)ct-dependent mechanism that may involve competition for the transcriptional coactivator cAMP responsive element (CRE)-binding protein (CREB)-binding protein (CBP) between the steroid receptor and c-Jun/c-Fos heterodimer. The identification of a second form of GnRH from chicken hypothalamus (termed GnRH-II) revealed that it is the most widely expressed form of GnRH and that its structure is conserved over all vertebrate classes from primitive fishes to humans. However, the molecular mechanism governing human GnRH-II gene transcription is poorly understood. Here we have shown that two E-box binding sites (EBSs) and one Ets-like element (ELE) in the untranslated first exon function cooperatively to stimulate the basal transcription of the GnRH-II gene and demonstrated that the basic helix-loophelix (bHLH) transcription factor AP-4 is an enhancer protein for the GnRH-II promoter. The results of this research provide novel and significant insights into the molecular mechanisms underlying the multi-faceted actions of GnRH in humans.

description: We observe mixing between two-electron singlet and triplet states in a double quantum dot, caused by interactions with nuclear spins in the host semiconductor. This mixing is suppressed by applying a small magnetic field, or by increasing the interdot tunnel coupling and thereby the singlet-triplet splitting. Electron transport involving transitions between triplets and singlets in turn polarizes the nuclei, resulting in striking bistabilities. We extract from the fluctuating nuclear field a limitation on the time-averaged spin coherence time T2* of 25 ns. Control of the electron-nuclear interaction will therefore be crucial for the coherent manipulation of individual electron spins.

description: Typical architectures of Generative AdversarialNetworks make use of a unimodal latent distribution transformed by a continuous generator. Consequently, the modeled distribution always has connected support which is cumbersome when learning a disconnected set of manifolds. We formalize this problem by establishing a no free lunch theorem for the disconnected manifold learning stating an upper bound on the precision of the targeted distribution. This is done by building on the necessary existence of a low-quality region where the generator continuously samples data between two disconnected modes. Finally, we derive a rejection sampling method based on the norm of generators Jacobian and show its efficiency on several generators including BigGAN.

description: This article examines the effects of R&D on cotton yield and relationship between R&D and commodity support programs. The results indicate that yield elasticities with respect to cotton R&D is around 0.2-0.5 based on different regions. It further indicates that R&D increases government expenditures when both commodity programs and R&D funding exist. However, if the future WTO Doha negotiations rules out the possibility of price support programs, increasing R&D funding may provide one of the solutions for farmers to recover their income with 5-6 years lag.

description: This thesis studies risk-sharing equilibria where trading is subject to transaction costs. In an infinite-horizon model with specific state dynamics and exogenous price volatility but general convex trading costs, we determine equilibrium prices and trading strategies in closed form and show how this allows us to calibrate the model to time-series datafor prices and trading volume. For more general state dynamics and endogenous volatilities, equilibria with transaction costs correspond to fully-coupled systemsof nonlinear forward-backward stochastic differential equations. We propose a simulation-based deep-learning algorithm that allows us to approximate the solution of such systems numerically. For quadratic trading costs and specific state dynamics, we complement this with a global wellposedness result. As a byproduct, the latter also yields explicit asymptotic expansions of the equilibrium for small transaction costs. These small-cost asymptotics formally extend to models with general state dynamics, transaction costs, and endogenous volatilities, leading to explicit asymptotic approximations of equilibrium prices with general trading costs.

description: Analysing (e,e'p) experimental data involves corrections for radiative effects which change the interaction kinematics and which have to be carefully considered in order to obtain the desired accuracy. Missing momentum and energy due to bremsstrahlung have so far always been calculated using the peaking approximation which assumes that all bremsstrahlung is emitted in the direction of the radiating particle. In this article we introduce a full angular Monte Carlo simulation method which overcomes this approximation. The angular distribution of the bremsstrahlung photons is reconstructed from H(e,e'p) data. Its width is found to be underestimated by the peaking approximation and described much better by the approach developed in this work.

description: Measurements by the Belle Collaboration of the exclusive production of two charmonia in e^+ e^- annihilation differ substantially from theoretical predictions. Till now, no conclusive explanation for this remarkable discrepancy has been provided. Even the origin of the discrepancy is not identified, yet. We suggest that the measurement of four-charm events in Belle data must provide a strong constraint in identifying the origin of this large discrepancy. Our prediction of the cross section for e^+e^- -> c c-bar c c-bar, in lowest order in strong coupling constant, at sqrt{s}=10.6 GeV is about 0.1 pb. If measured four-charm cross section is compatible with the prediction based on perturbative QCD, it is very likely that factorization of hadronization process from perturbative part may be significantly violated or there exists a new production mechanism. If the cross section for the four-charm event is also larger than the prediction like that for the exclusive J/psi+eta_c production, perturbative QCD expansion itself will be proved to be unreliable and loses predictive power.

Dynamic Independent Component/Vector Analysis: Time-Variant Linear Mixtures Separable by Time-Invariant Beamformers

description: A novel extension of Independent Component and Independent Vector Analysis for blind extraction/separation of one or several sources from time-varying mixtures is proposed. The mixtures are assumed to be separable source-by-source in series or in parallel based on a recently proposed mixing model that allows for the movements of the desired source while the separating beamformer is time-invariant. The popular FastICA algorithm is extended for these mixtures in one-unit, symmetric and block-deflation variants. The algorithms are derived within a unified framework so that they are applicable in the real-valued as well as complex-valued domains, and jointly to several mixtures, similar to Independent Vector Analysis. Performance analysis of the one-unit algorithm is provided; it shows its asymptotic efficiency under the given mixing and statistical models. Numerical simulations corroborate the validity of the analysis, confirm the usefulness of the algorithms in separation of moving sources, and show the superior speed of convergence and ability to separate super-Gaussian as well as sub-Gaussian signals.

description: Controlling the pump beam transverse profile in multimode Hong-Ou-Mandel interference, we generate a ''localized" two-photon singlet state, in which both photons propagate in the same beam. This type of multi-photon singlet beam may useful in quantum communication to avoid decoherence. We show that although the photons are part of the same beam, they are never in the same plane wave mode, which is characterized by spatial antibunching behavior in the plane normal to the propagation direction.

description: A solid methodology to understand human perception and preferences in human-robot interaction (HRI) is crucial in designing real-world HRI. Social cognition posits that the dimensions Warmth and Competence are central and universal dimensions characterizing other humans. The Robotic Social Attribute Scale (RoSAS) proposes items for those dimensions suitable for HRI and validated them in a visual observation study. In this paper we complement the validation by showing the usability of these dimensions in a behavior based, physical HRI study with a fully autonomous robot. We compare the findings with the popular Godspeed dimensions Animacy, Anthropomorphism, Likeability, Perceived Intelligence and Perceived Safety. We found that Warmth and Competence, among all RoSAS and Godspeed dimensions, are the most important predictors for human preferences between different robot behaviors. This predictive power holds even when there is no clear consensus preference or significant factor difference between conditions.

description: Many cities need a space for its further development with a criterion to capture everything that would run it with ease without any difficulties. The future demand of each city will ultimately in the favor to attract the population and living demand. This demand leads to the progress of the multistoried building. To counteract the lateral forces and stand in its position, the tall structures need stability with or without any improvement in the same. The current work is going to show the stability criteria of changing the grades of beams without altering the size at various floor levels. Total 6 cases of the current theme created and analyzed with the help of software approach after then result is compared. Result shows that the increase of stability has seen in Case BS3 and BS4 and would be recommended whenever this type of stability activity performed.
