title: An adaptive moving finite element method for steady low Mach number compressible combustion problems

Publisher: name: John Wiley & Sons
Year: 2024

description: This work surveys an r‐adaptive moving mesh finite element method for the numerical solution of premixed laminar flame problems. Since the model of chemically reacting flow involves many different modes with diverse length scales, the computation of such a problem is often extremely time‐consuming. Importantly, to capture the significant characteristics of the flame structure when using detailed chemistry, a much more stringent requirement on the spatial resolution of the interior layers of some intermediate species is necessary. Here, we propose a moving mesh method in which the mesh is obtained from the solution of so‐called moving mesh partial differential equations. Such equations result from the variational formulation of a minimization problem for a given target functional that characterizes the inherent difficulty in the numerical approximation of the underlying physical equations. Adaptive mesh movement has emerged as an area of intense research in mesh adaptation in the last decade. With this approach, points are only allowed to be shifted in space leaving the topology of the grid unchanged. In contrast to methods with local refinement, data structure hence is unchanged and load balancing is not an issue as grid points remain on the processor where they are. We will demonstrate the high potential of moving mesh methods for effectively optimizing the distribution of grid points to reach the required resolution for chemically reacting flows with extremely thin boundary layers.

description: In two-dimensional antiferromagnets, we identify the mixed Berry curvature as the geometrical origin of the nonreciprocal directional dichroism (NDD), which refers to the difference in light absorption with the propagation direction flipped. Such a Berry curvature is strongly tied to the uniaxial strain in accordance with the symmetry constraint, leading to a highly tunable NDD, whose sign and magnitude can be manipulated via the strain direction. As a concrete example, we demonstrate such a phenomenon in a lattice model of MnBi2Te4. The coupling between the mixed Berry curvature and strain also suggests the magnetic quadrupole of the Bloch wave packet as the macroscopic order parameter probed by the NDD in two dimensions, distinct from the multiferroic order P times M or the spin toroidal and quadrupole order within a unit cell in previous studies. Our work paves the way of the Berry-curvature engineering for optical nonreciprocity in two-dimensional antiferromagnets.

description: In the context of the upcoming SRG/eROSITA survey, we present an N-body simulation-based mock catalogue for X-ray selected AGN samples. The model reproduces the observed hard X-ray AGN luminosity function (XLF) and the soft X-ray logN-logS from redshift 0 to 6. The XLF is reproduced to within $\pm5\%$ and the logN-logS to within $\pm20\%$. We develop a joint X-ray -- optical extinction and classification model. We adopt a set of empirical spectral energy distributions to predict observed magnitudes in the UV, optical and NIR. With the latest eROSITA all sky survey sensitivity model, we create a high-fidelity full-sky mock catalogue of X-ray AGN. It predicts their distributions in right ascension, declination, redshift and fluxes. Using empirical medium resolution optical spectral templates and an exposure time calculator, we find that $1.1\times10^6$ ($4\times10^5$) fiber-hours are needed to follow-up spectroscopically from the ground the detected X-ray AGN with an optical magnitude $21

description: The rare earth nickel borocarbides, with the generic formula $R$Ni$_{2}$B$_{2}$C, have recently been shown to display a rich variety of phenomena. Most striking has been the competition between, and even coexistence of, antiferromagnetism and superconductivity. We have measured the Fermi surface (FS) of LuNi$_{2}$B$_{2}$C, and shown that it possesses nesting features capable of explaining some of the phenomena experimentally observed. In particular, it had previously been conjectured that a particular sheet of FS is responsible for the modulated magnetic structures manifest in some of the series. We report the first direct experimental observation of this sheet.

What has been less studied is the impact of a more pervasive - although often less overt and quantifiable – form of gender discrimination. Evidence from research in the workplace demonstrates that day-to-day, more subtle words and actions can also negatively impact a woman's sense of well-being and success – in a way that is: Often unrecognized outside the experience of women herself, and commonly left to the woman to decide how and whether to address it

description: The C-Band All-Sky Survey (C-BASS) is an all-sky full-polarization survey at a frequency of 5 GHz, designed to provide data complementary to the all-sky surveys of WMAP and Planck and future CMB B-mode polarization imaging surveys. We describe the design and performance of the digital backend used for the northern part of the survey. In particular we describe the features that efficiently implement the demodulation and filtering required to suppress contaminating signals in the time-ordered data, and the capability for real-time correction of detector non-linearity and receiver balance.

description: Perturbative QCD predicts the behavior of scattering at high energies and fixed (sufficiently large) transferred momenta in terms of the BFKL pomeron (or short distance pomeron). We study the prospects for testing these predictions in two-photon processes at LEP200 and a possible future e+ e- collider. We argue that the total cross section for scattering two photons sufficiently far off shell provides a clean probe of BFKL dynamics. The photons act as color dipoles with small transverse size, so that the QCD interactions can be treated perturbatively. We analyze the properties of the QCD result and the possibility of testing them experimentally. We give an estimate of the rates expected and discuss the uncertainties of these results associated with the accuracy of the present theoretical calculations.

description: Both the Bern, Carrasco and Johansson (BCJ) and the Kawai, Lewellen and Tye (KLT) double-copy formalisms have been recently generalized to a class of scattering matrix elements (so-called form factors) that involve local gauge-invariant operators. In this paper we continue the study of double copy for form factors. First, we generalize the double-copy prescription to form factors of higher-length operators ${\rm tr}(ϕ^m)$ with $m\geq3$. These higher-length operators introduce new non-trivial color identities, but the double-copy prescription works perfectly well. The closed formulae for the CK-dual numerators are also provided. Next, we discuss the $\vec{v}$ vectors which are central ingredients appearing in the factorization relations of both the KLT kernels and the gauge form factors. We present a general construction rule for the $\vec{v}$ vectors and discuss their universal properties. Finally, we consider the double copy for the form factor of the ${\rm tr}(F^2)$ operator in pure Yang-Mills theory. In this case, we propose a new prescription that involves a gauge invariant decomposition for the form factor and a combination of different CK-dual numerators appearing in the expansion.

description: Context. Solar Rossby waves (r modes) have recently been discovered in the near-surface horizontal flow field using the techniques of granulation-tracking and ring-diagram analysis applied to six years of SDO/HMI data. Aims. Here we apply time-distance helioseismology to the combined SOHO/MDI and SDO/HMI data sets, which cover 21 years of observations from May 1996 to April 2017. The goal of this study is to provide an independent confirmation over two solar cycles and in deeper layers of the Sun. Methods. We have measured south-north helioseismic travel times along the equator, which are sensitive to subsurface north-south flows. To reduce noise, the travel times were averaged over travel distances from 6$^\circ$ to 30$^\circ$; the mean distance corresponds to a p-mode lower turning point of 0.91 $R_\odot$. The 21-year time series of travel-time measurements was split into three seven-year subsets and transformed to obtain power spectra in a corotating frame. Results. The power spectra all show peaks near the frequencies of the classical sectoral Rossby waves for azimuthal wavenumbers in the range $3 \leq m \leq 15$. The mode frequencies and linewidths of the modes with $m \leq 9$ are consistent with a previous study whereas modes with $m \geq 10$ are shifted toward less negative frequencies by 10--20 nHz. While most of these modes have e-folding lifetimes on the order of a few months, the longest lived mode, $m=3$, has an e-folding lifetime of more than one year. For each mode, the rms velocity at the equator is in the range of 1--3 m s$^{-1}$ , with the largest values for $m\sim10$. No evidence for the $m=2$ sectoral mode is found in the power spectrum, implying that the rms velocity of this mode is below $\sim$0.5 m s$^{-1}$.

description: The gridding of daily accumulated precipitation -- especially extremes -- from ground-based station observations is problematic due to the fractal nature of precipitation, and therefore estimates of long period return values and their changes based on such gridded daily data sets are generally underestimated. In this paper, we characterize high-resolution changes in observed extreme precipitation from 1950 to 2017 for the contiguous United States (CONUS) based on in situ measurements only. Our analysis utilizes spatial statistical methods that allow us to derive gridded estimates that do not smooth extreme daily measurements and are consistent with statistics from the original station data while increasing the resulting signal to noise ratio. Furthermore, we use a robust statistical technique to identify significant pointwise changes in the climatology of extreme precipitation while carefully controlling the rate of false positives. We present and discuss seasonal changes in the statistics of extreme precipitation: the largest and most spatially-coherent pointwise changes are in fall (SON), with approximately 33% of CONUS exhibiting significant changes (in an absolute sense). Other seasons display very few meaningful pointwise changes (in either a relative or absolute sense), illustrating the difficulty in detecting pointwise changes in extreme precipitation based on in situ measurements. While our main result involves seasonal changes, we also present and discuss annual changes in the statistics of extreme precipitation. In this paper we only seek to detect changes over time and leave attribution of the underlying causes of these changes for future work.

description: In non-diagonal conformal models, the boundary fields are not directly related to the bulk spectrum. We illustrate some of their features by completing previous work of Lewellen on sewing constraints for conformal theories in the presence of boundaries. As a result, we include additional open sectors in the descendants of $D_{odd}$ $SU(2)$ WZW models. A new phenomenon emerges, the appearance of multiplicities and fixed-point ambiguities in the boundary algebra not inherited from the closed sector. We conclude by deriving a set of polynomial equations, similar to those satisfied by the fusion-rule coefficients $N_{ij}^k$, for a new tensor $A_{a b}^i$ that determines the open spectrum.

description: The interplay between topology and electronic correlation effects offers a rich avenue for discovering emergent quantum phenomena in condensed matter systems. In this work, starting from the Weyl-Hubbard model, we investigate the quantum Hall effect to explore the consequence of onsite Hubbard repulsion on nontrivial Weyl band topology in the presence of an external magnetic field. Within the Gutzwiller projected wavefunction method, we find the system to undergo multiple topological phase transitions, including two distinct Weyl phases with a different number of Weyl node pairs and a trivial narrow band insulator, by tuning on-site Coulomb interaction. Interestingly, these two Weyl phases can be identified by the sign of their chiral Landau levels. The possible experimental signature of these topological phases and correlation effects is provided by the magnetic-field dependent quantum Hall conductivity within the Kubo response theory.

Detuning control of Rabi vortex oscillations in light matter coupling

Year: 2019
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We study analytically the dynamics of vortices in strongly coupled exciton--photon fields in the presence of energy detuning. We derive equations for the vortex core velocity and mass, where they mainly depend on Rabi coupling and the relative distance between the vortex cores in photon and exciton fields, and as the result core positions oscillate in each field. We use Magnus force balanced with a Rabi induced force to show that the core of the vortex behaves as an inertial-like particle. Our analysis reveals that the core is lighter at periphery of the beam and therefore it is faster at that region. While detuning induces oscillations in population imbalance of components through relative phase between coupled fields, in the presence of topological charges detuning can control the orbital dynamics of the cores. Namely, it brings the vortex core to move on larger or smaller orbits with different velocities, and changes angular momentum and energy content of vortex field.

description: In early 2017 we deployed eight KOSMOS [a] mesocosm units (53 m^3 each) close to ‘Isla San Lorenzo’ about 4.5 nm off-shore the Peruvian coastline (-12.0554667°, -077.2347667°). The aim of the study was to improve our mechanistic understanding of processes controlling plankton productivity, organic matter export, and particle stoichiometry in the coastal upwelling system off Peru. About 40 days into the study, Inca terns (Larosterna inca) – an abundant sea bird species in the region – discovered the mesocosms as suitable resting places. The birds were able to start and land on the very small areas lacking anti-bird spikes that were installed on the mesocosm roofs. Resting on the flotation frames as well as the opening of the mesocosm bags, they defecated into the enclosed water columns, adding new nutrients to the system. This orni-eutrophication from day 40 to 50 triggered intense phytoplankton blooms in the uppermost part of the enclosures where light was plentiful. This video illustrates the fertilizing effect of Inca tern defecation on phytoplankton communities during our mesocosm study in the upwelling system off Peru.

description: In this study, a facile method to fabricate a cohesive ion‐gel based gate insulator for electrolyte‐gated transistors is introduced. The adhesive and flexible ion‐gel can be laminated easily on the semiconducting channel and electrode manually by hand. The ion‐gel is synthesized by a straightforward technique without complex procedures and shows a remarkable ionic conductivity of 4.8 mS cm⁻¹ at room temperature. When used as a gate insulator in electrolyte‐gated transistors (EGTs), an on/off current ratio of 2.24×10⁴ and a subthreshold swing of 117 mV dec⁻¹ can be achieved. This performance is roughly equivalent to that of ink drop‐casted ion‐gels in electrolyte‐gated transistors, indicating that the film‐attachment method might represent a valuable alternative to ink drop‐casting for the fabrication of gate insulators.
Implementing multi-method transgender education into a baccalaureate nursing program

description: Purpose of Project:Transgender health is a research priority to address disparities and alarming rates of discrimination, stigmatization, and violence often inflicted by healthcare providers. Research depicts nursing education gaps regarding transgender health. Lack of exposure and learning application perpetuates negative attitudes and incompetence impeding future clinical practice when working with transgender individuals.MethodologyA multi-method transgender education program was created for junior-level baccalaureate nursing students at RUSON Blackwood Campus. The program utilized a contact education seminar followed by a clinical simulation for knowledge application. The Transgender Attitudes and Beliefs Scale (TABS) assessed the knowledge, attitudes, and comfort levels of nursing students. TABS was completed at three critical points: Pre-intervention, between education methods, and Post-intervention, to assess the effectiveness of each intervention and the overall study.Results: This study sought to increase knowledge, change attitudes, and improve comfort levels of junior-level baccalaureate nursing students when caring for transgender clients. Project results revealed a significant increase in knowledge and comfort levels only after completion of both the seminar and simulation. This project aligns with current research supporting multiple education methods to affect change in knowledge and comfort of baccalaureate nursing students. Attitudes toward transgender individuals were consistently positive throughout the project.Implications on Practice: Study findings support current research that multi-method education models are needed to promote trans-affirmative practice. This project’s transgender education interventions can be easily adapted into baccalaureate nursing curricula with little to no financial constraints. Also, the primary prevention nature contributes to an innovative approach at systemically reducing poor health outcomes and associated healthcare costs. It is imperative that the future of nursing is exposed to quality education that cultivates equity and inclusion for transgender people.

description: An efficient characterization of scientifically significant locations is essential prior to the return of humans to the Moon. The highest resolution imagery acquired from orbit of south-polar shadowed regions and other relevant locations remains, at best, an order of magnitude larger than the characteristic length of most of the robotic systems to be deployed. This hinders the planning and successful implementation of prospecting missions and poses a high risk for the traverse of robots and humans, diminishing the potential overall scientific and commercial return of any mission. We herein present the design of a lightweight, compact, autonomous, and reusable lunar reconnaissance drone capable of assisting other ground-based robotic assets, and eventually humans, in the characterization and high-resolution mapping (~0.1 m/px) of particularly challenging and hard-to-access locations on the lunar surface. The proposed concept consists of two main subsystems: the drone and its service station. With a total combined wet mass of 100 kg, the system is capable of 11 flights without refueling the service station, enabling almost 9 km of accumulated flight distance. The deployment of such a system could significantly impact the efficiency of upcoming exploration missions, increasing the distance covered per day of exploration and significantly reducing the need for recurrent contacts with ground stations on Earth.

description: The flow of superfluid 3He-B through a 65 x 65 array of nanometer size apertures has been measured recently by Backhaus et al. They find in the current--phase relation a new branch, so-called pi state. We study two limiting cases which show that the pi state arises from coupling of the phase degree of freedom to the spin-orbit rotation. The pi state exists in a single large aperture, but is difficult to observe because of hysteresis. A better correspondence with experiments is obtained by assuming a thin wall, where the Josephson coupling between the two sides arises from a dense array of pin-holes.

description: An algebraic representation of three generations of fermions with $SU(3)_C$ color symmetry based on the Cayley-Dickson algebra of sedenions $\mathbb{S}$ is constructed. Recent constructions based on division algebras convincingly describe a single generation of leptons and quarks with Standard Model gauge symmetries. Nonetheless, an algebraic origin for the existence of exactly three generations has proven difficult to substantiate. We motivate $\mathbb{S}$ as a natural algebraic candidate to describe three generations with $SU(3)_C$ gauge symmetry. We initially represent one generation of leptons and quarks in terms of two minimal left ideals of $\mathbb{C}\ell(6)$, generated from a subset of all left actions of the complex sedenions on themselves. Subsequently we employ the finite group $S_3$, which are automorphisms of $\mathbb{S}$ but not of $\mathbb{O}$ to generate two additional generations. Given the relative obscurity of sedenions, efforts have been made to present the material in a self-contained manner.

description: The combined requirements, of (i) a natural solution to the fermion mass hierarchy problem and (ii) an explanation of both the atmospheric and solar neutrino problems, lead to an essentially unique picture of neutrino masses and mixing angles. The electron and muon neutrinos are quasi-degenerate in mass with maximal mixing, giving $ν_e - ν_μ$ vacuum oscillations. The overall neutrino mass scale is set by the atmospheric neutrino requirement $Δm^2 \sim 10^{-2}$ eV$^2$, implying a mass for $ν_e$ and $ν_μ$ of order 1 eV in models with a natural mass hierarchy, whilst the tau neutrino is expected to be much lighter than this and only weakly mixed. We present an explicit example based on the anti-grand unification model of fermion masses.

description: Energy harvesting from vibrations provides power to low‐energy‐consuming electronics for standalone and wearable devices as well as for wireless and remote sensing. In this contribution, compact tubular ferroelectret energy harvesters utilizing a single‐tube design are presented. Such single‐tube harvesters can be fabricated from commercially available fluorinated ethylene propylene (FEP) tubes with wall thicknesses of 25 and 50 μm, respectively, by mechanical deformation at elevated temperature. It is demonstrated that the generated power is highly dependent on parameters such as wall thickness, load resistance, and seismic mass. Utilizing a seismic mass of 80 g at resonance frequencies around 80 Hz and an input acceleration of 1 × g (9.81 m s⁻² rms), output powers up to 300 μW can be reached for a transducer with 25 μm thick walls.

description: Transition metal dichalcogenide superlattices provide an exciting new platform for exploring and understanding a variety of phases of matter. The moiré continuum Hamiltonian, of two-dimensional jellium in a modulating potential, provides a fundamental model for such systems. Accurate computations with this model are essential for interpreting experimental observations and making predictions for future explorations. In this work, we combine two complementary quantum Monte Carlo (QMC) methods, phaseless auxiliary field quantum Monte Carlo and fixed-phase diffusion Monte Carlo, to study the ground state of this Hamiltonian. We observe a metal-insulator transition between a paramagnetic and a $120^\circ$ Néel ordered state as the moiré potential depth and the interaction strength are varied. We find significant differences from existing results by Hartree-Fock and exact diagonalization studies. In addition, we benchmark density-functional theory, and suggest an optimal hybrid functional which best approximates our QMC results.

description: A two-level system interacting with a cavity field is an important model for investigating the photon blockade (PB) effect. Most work on this topic has been based on the assumption that the atomic transition frequency is resonant with the fundamental mode frequency of the cavity. We relax this constraint and reexamine PB in a more general atom--cavity system with arbitrary atomic and cavity detunings from a driving field. The results show that when the signs of the atomic and cavity detunings are the same, PB occurs only in the strong-coupling regime, but for opposite signs of the atomic and cavity detunings, strong photon antibunching is observed in both the weak- and strong-coupling regimes and a better PB effect is achieved compared with the case when the signs are the same. More interestingly, we find that this PB arises from quantum interference for both weak and strong nonlinearities. These results deepen our understanding of the underlying mechanism of PB and may be help in the construction of single-photon sources with higher purity and better flexibility using atom--cavity systems.

description: We have measured the energy and momentum dependent loss function of Li_2CuO_2 single crystals by means of electron energy-loss spectroscopy in transmission. Using the same values for the model parameters, the low-energy features of the spectrum as well as published Cu 2p_(3/2) x-ray photoemission data of Li_2CuO_2 are well described by a cluster model that consists of a single CuO_4 plaquette only. This demonstrates that charge excitations in Li_2CuO_2 are strongly localized.

description: During the 1980s, a novel pedagogical approach known as Task-based Language Teaching gained prominence within Western education. This methodology is characterized by its pragmatic application, emphasizing the integration of specific communication and language-oriented tasks throughout the instructional process. Distinguished by its clear content and operational simplicity, Task-based Language Teaching has garnered widespread popularity within contemporary educational spheres. This review paper critically examines and consolidates the definitions and classifications of tasks inherent in Task-based Language Teaching, drawing insights from various scholarly perspectives and previous research on the subject. Additionally, the article outlines two implementation models proposed by Willis and Ellis for the execution of Task-based Language Teaching.

Furthermore, the paper underscores the practical efficacy of Task-based Language Teaching by citing the empirical studies of three forerunners in the field, exemplifying its application in authentic English classrooms. In elucidating the method's strengths and weaknesses, the article delves into an analysis of the advantages and disadvantages associated with Task-based Language Teaching. It concludes by providing recommendations on how educators can adeptly design tasks to mitigate potential drawbacks and enhance teaching efficiency when employing this pedagogical approach.

description: We study the majority rule transformation applied to the Gibbs measure for the 2--D Ising model at the critical point. The aim is to show that the renormalized hamiltonian is well defined in the sense that the renormalized measure is Gibbsian. We analyze the validity of Dobrushin-Shlosman Uniqueness (DSU) finite-size condition for the "constrained models" corresponding to different configurations of the "image" system. It is known that DSU implies, in our 2--D case, complete analyticity from which, as it has been recently shown by Haller and Kennedy, Gibbsianness follows. We introduce a Monte Carlo algorithm to compute an upper bound to Vasserstein distance (appearing in DSU) between finite volume Gibbs measures with different boundary conditions. We get strong numerical evidence that indeed DSU condition is verified for a large enough volume $V$ for all constrained models.

description: Many features of physical systems, both qualitative and quantitative, become sharply defined or tractable only in some limiting situation. Examples are phase transitions in the thermodynamic limit, the emergence of classical mechanics from quantum theory at large action, and continuum quantum field theory arising from renormalization group fixed points. It would seem that few methods can be useful in such diverse applications. However, we here present a flexible modeling tool for the limit of theories: soft inductive limits constituting a generalization of inductive limits of Banach spaces. In this context, general criteria for the convergence of dynamics will be formulated, and these criteria will be shown to apply in the situations mentioned and more.

description: Purpose of Project:Transgender health is a research priority to address disparities and alarming rates of discrimination, stigmatization, and violence often inflicted by healthcare providers. Research depicts nursing education gaps regarding transgender health. Lack of exposure and learning application perpetuates negative attitudes and incompetence impeding future clinical practice when working with transgender individuals. MethodologyA multi-method transgender education program was created for junior-level baccalaureate nursing students at RUSON Blackwood Campus. The program utilized a contact education seminar followed by a clinical simulation for knowledge application. The Transgender Attitudes and Beliefs Scale (TABS) assessed the knowledge, attitudes, and comfort levels of nursing students. TABS was completed at three critical points: Pre-intervention, between education methods, and Post-intervention, to assess the effectiveness of each intervention and the overall study. Results:This study sought to increase knowledge, change attitudes, and improve comfort levels of junior-level baccalaureate nursing students when caring for transgender clients. Project results revealed a significant increase in knowledge and comfort levels only after completion of both the seminar and simulation. This project aligns with current research supporting multiple education methods to affect change in knowledge and comfort of baccalaureate nursing students. Attitudes toward transgender individuals were consistently positive throughout the project. Implications on Practice:Study findings support current research that multi-method education models are needed to promote trans-affirmative practice. This project’s transgender education interventions can be easily adapted into baccalaureate nursing curricula with little to no financial constraints. Also, the primary prevention nature contributes to an innovative approach at systemically reducing poor health outcomes and associated healthcare costs. It is imperative that the future of nursing is exposed to quality education that cultivates equity and inclusion for transgender people.

Subjects: Purchasing decision, Fashion, Quality, Price, Brand, and Imported cloth

description: Quality, fashion, price, brand, and the presence of imported cloths on market are determinant
 factors that affect customers purchasing decision for domestically produced cloths. This
 research is descriptive in nature and described factors affecting consumers purchasing decision
 for domestic garment products on consumers and producers perspectives. Assess consumer’s
 attitude toward domestic cloths, and producers understanding and attitude they have for their
 products, and for consumers. Data collected from 269 consumers at Menegagna round on
 Derartu Tulu building and 4 selected producers at Haile Garment round. The data were
 analyzed through the help of SPSS. The result from analysis revealed that, consumers respond
 that their purchasing decision for domestic cloths affected by the given factors, and Consumers
 almost most of them thought domestic cloths have weak in their fashion, brand, but moderate
 and a little sided to not good for their price, and quality. Producers on the other side thought
 their product have good fashion, quality, and the price but different responses for their
 popularity of their brand. These shows producers didn’t know consumer’s perception and
 attitude they have for their cloths, and didn’t know how much they are affected by the factors
 especially by fashion, and quality. For this research age groups 22-27, 28-35, 36-42, and income
 status grouped under 2001-5000, 5001-9000, 9001-14000 have high frequency, based on their
 frequency these groups highly affected by all factors. Producers Recommended, that they should
 have a good communication and relation with their consumers and they should know their needs
 and wants. Producers should identify who are their target consumers; they should improve using
 technology and technological systems and compete with imported cloths.
