description: We study cosmology in a five-dimensional brane-world with a stabilizing effective potential for the radion and matter localized on the two branes. We consider the corrections induced by the Gauss-Bonnet contribution to the total action performing and expansion around the two possible static solutions up to second order in the ratio between brane matter energy density and brane tensions. The Friedmann and acceleration equations on the visible brane are obtained and discussed.

Numerical simulation of fiber separation in hydrocyclones
Creators: name: Wang, Zheqiong
Publisher: name: University of British Columbia
Year: 2009

description: Hydrocyclones are used in the pulp and paper industry to eliminate undesirable particles as well as for fiber fractionation. This current thesis is focused on modeling the performance of hydrocyclone, which can be used to predict and optimize the hydrocyclone design. The computational model developed in this study consists of two models. The flow model is a three-dimensional k-e turbulence model. The Navier-Stokes equations are solved in a curvilinear coordinate system. The Launder correction is used to model the turbulence in the highly swirling flow. Then the flow model is coupled with a Lagrangian tracking of solid particles representing the fibers. The fiber model allows for the motion in three dimensions. Fibers are constituted of ellipsoids and allow for the representation of flexible behavior. Interaction with the wall is implemented. Separation characteristics are investigated for different fiber properties and hydrocyclone design parameters. The predictions of the proposed model are compared with elaborate published experimental data sets. Good agreement is obtained between the model predictions and the experimental data.

description: Spark gaps are likely the source of plasma in active black hole (BH) magnetospheres. In this paper, we present results of 1D general-relativistic particle-in-cell simulations of a starved BH magnetosphere with a realistic treatment of inverse Compton scattering and pair production, for a broad range of conditions, run times longer than in previous studies, and different setups. We find that following the initial discharge, the system undergoes gradual evolution over prolonged time until either, restoring the vacuum state or reaching a state of quasi-periodic oscillations, depending on the spectral shape and luminosity of the ambient radiation field. The oscillations occur near the null charge surface in cases where the global magnetospheric current is in the direction defined by the product of the asymptotic Goldreich-Julian charge density and the radial velocity, while they occur near the boundary of the simulation box when it is the opposite direction (return current). Their amplitude and the resultant luminosity of TeV photons emitted from the gap depend sensitively on the conditions; for the cases studied here the ratio of TeV luminosity to the Blandford-Znajek power ranges from $10^{-5}$ to $10^{-2}$, suggesting that strong flares may be generated by moderate changes in disk emission. We also examined the dependence of the solution on the initial number of particles per cell (PPC) and found convergence for PPC of about 50 for the cases examined. At lower PPC values the pair multiplicity is found to be artificially high, affecting the solution considerably.

description: We present the first study of the dynamic scaling or multiscaling of passive-scalar and passive-vector turbulence. For the Kraichnan version of passive-scalar and passive-vector turbulence we show analytically, in both Eulerian and quasi-Lagrangian frameworks, that simple dynamic scaling is obtained but with different dynamic exponents. By developing the multifractal model we show that dynamic multiscaling occurs in passive-scalar turbulence only if the advecting velocity field is itself multifractal. We substantiate our results by detailed numerical simulations in shell models of passive-scalar advection.

A Cellular Diagonal Approximation On The Sequence Of Associahedra
Creators: name: Fleming, Kieran
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: The chain complexes on the sequence of associahedra de?ne a differential graded A1 operad. A diagonal approximation on the associahedra is therefore equivalent to exhibiting an A1 structure on a product of A1 algebras. In the following we construct a direct formula for the cell decomposition on the associahedra, corresponding to the diagonal, and give formulae for the number of cells in the resulting decomposition. Examples of the results in low dimension are also provided. We then apply the formula for the diagonal in two ways; firstly to investigate the explicit topological operad structure on the Loday realisation of the associahedra, and secondly to construct twisting cochains from an A1 coalgebra to an A1 algebra. We also consider possible approaches to measuring the obstruction to coassociativity inherent in the diagonal approximation however we do not give any new results. In the appendix we also provide an algorithm for a alternative labelling of triangulations of the associahedra to that appearing in [Lod07b].

CP-violating theta parameter in the domain model of the QCD vacuum

description: A non-zero CP-violating $θ$ parameter is treated in the domain model which assumes a cluster-like vacuum structure whose units are characterised in particular by a topological charge which is not necessarily an integer number. In the present paper we restrict consideration to rational values of the charge. The model has previously been shown to manifest confinement, spontaneous chiral symmetry breaking and the absence of an axial U(1) Goldstone boson. We find that the specific structure of the minima of the free energy density of the domain ensemble forces a $2π$-periodicity of observables in $θ$ for any number of light quarks, that vacuum doubling occurs at $θ=π$ for any $N_f>1$ and any value of topological charge $q$. These features are in agreement with expectations based on anomalous Ward identities and large $N_c$ effective theories. We find also additional values of $θ$ depending on $q$ for which vacuum doubling occurs.

title:  Refonder l’esthétique plasticienne selon Sartre. Post-surréalisme, expressionnisme, déconstruction
Creators: name: Sicard , Michel
Publisher: name: Roma TrE-Press
Year: 2021

description: Questo articolo cerca di mostrare la costituzione di un'estetica asistematica e frammentata di Sartre. Prima legata all'idea di Bellezza, l'estetica sartriana mescola i generi, a partire dagli articoli su Calder e David Hare, per scuotere le categorie ereditate da Hegel, per avventurarsi verso altre concezioni dell'emozione e della cognizione artistica. All'immaginario, si aggiungono le pulsioni elementari responsabili della comunicazione dell'opera. Una svolta appare nella scelta degli artisti sartriani, che vanno dagli antichi surrealisti ai promotori dell'espressionismo astratto. Sartre accoglie un certo materialismo che lo distacca dal simbolico e lo avvicina a Wols, al tachismo e alla gestualità. L'estetica è dunque per Sartre un processo di decostruzione del Soggetto e della rappresentazione, che egli conduce da Giacometti a Tintoretto, passando per Masson, Lapoujade, Rebeyrolle, sfuggendo a sistemi di visione o ideologie di assegnazione dell'arte a un messaggio, per affermare nella creazione un'avventura attraverso i materiali e una forza intrinseca di liberazione.

description: In this paper we reconsider the problem of the Euler parametrization for the unitary groups. After constructing the generic group element in terms of generalized angles, we compute the invariant measure on SU(N) and then we determine the full range of the parameters, using both topological and geometrical methods. In particular, we show that the given parametrization realizes the group $SU(N+1)$ as a fibration of U(N) over the complex projective space $\mathbb{CP}^n$. This justifies the interpretation of the parameters as generalized Euler angles.

description: Computational implementations for solving systems of linear equations often rely on a one-size-fits-all approach based on LU decomposition of dense matrices stored in column-major format. Such solvers are typically implemented with the aid of the xGESV set of functions available in the low-level LAPACK software, with the aim of reducing development time by taking advantage of well-tested routines. However, this straightforward approach does not take into account various matrix properties which can be exploited to reduce the computational effort and/or to increase numerical stability. Furthermore, direct use of LAPACK functions can be error-prone for non-expert users and results in source code that has little resemblance to originating mathematical expressions. We describe an adaptive solver that we have implemented inside recent versions of the high-level Armadillo C++ library for linear algebra. The solver automatically detects several common properties of a given system (banded, triangular, symmetric positive definite), followed by solving the system via mapping to a set of suitable LAPACK functions best matched to each property. The solver also detects poorly conditioned systems and automatically seeks a solution via singular value decomposition as a fallback. We show that the adaptive solver leads to notable speedups, while also freeing the user from using direct calls to cumbersome LAPACK functions.
Impedance Spectroscopy Analysis Of Thermoelectric Materials For Radioisotope Space Power System Applications

Year: 2020
Subjects: Uncategorized

description: The European Space Agency (ESA) is currently supporting the research and development of a radioisotope thermoelectric generator (RTG) utilising americium-241 as a heat source and thermoelectric modules for thermal to electrical energy conversion. Initial design studies and a successful laboratory breadboard experimental campaign have demonstrated that bismuth telluride-based thermoelectric modules are a viable power conversion option with proven commercial manufacturing routes. However, although usable thermoelectric materials like bismuth telluride-based alloys have good heritage, their implementation into robust modules still to this day requires solving coupled challenges in both material development and systems engineering. Not to mention, for an RTG to continuously and reliably provide electrical power to spacecraft and or landers, their thermoelectric modules must be able to withstand mechanical trauma arising from pyroshock or random vibration associated with launch, stage separation, payload jettison and landing environments, as well as continuous thermal, thermomechanical and irradiation induced degradation. A proven understanding of their mechanical and thermoelectric properties in relation to the degradation mechanisms associated with operating in an RTG environment, is therefore highly necessary for mission acceptance. To be able to effectively address these challenges, advanced characterisation techniques are currently needed which rely on more factors than just traditional thermoelectric material performance metrics like the figure-of-merit.The work presented in this thesis details an advance implementation of impedance spectroscopy for characterising not only fundamental material-level properties of the constituent materials which make up a thermoelectric module, but also system-level performance and characteristics which correlate with manufacturing defects and in-service degradation mechanisms. Subsequently, three practical case studies were undertaken in this study which for the first time succefully demonstrates the feasibility of using impedance spectroscopy to characterise; the degradation of thermoelectric modules under in-service conditions like neutron irradiation, the inherent performance variation between identically manufactured modules from batch production, and the system-level performance of a newly synthesised thermoelectric material. For each case, candidate Bi2Te3-based thermoelectric modules for the European RTG program was investigated.

After reviewing the fundamental constants of nature and its universal laws, the new definitions of SI units are presented using, as a unifying principle, the discrete nature of energy, matter and information in these universal laws. The new SI system is here to stay: although the experimental realizations may change due to technological improvements, the definitions will remain unaffected. Quantum metrology is expected to be one of the driving forces to achieve new quantum technologies of the second generation. ----- La puesta en marcha en 2019 del nuevo sistema internacional de unidades es una oportunidad para resaltar el papel fundamental que las leyes fundamentales de la F\'ısica y la Qu\'ımica juegan en nuestra vida y en todos los procesos de la investigación fundamental, la industria y el comercio.

Altered Bodies, Changing Identities, Shifting Power: Trans/Posthumanism and the Reproduction of Humanity in Film and Video Game Fandom
Creators: name: McMillan, Callum T. F.
Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: This thesis investigates the theories of transhumanism and posthumanism, the former dealing with radically changing bodies and minds, and the latter with the nature of humanity itself. It examines how these theories are rapidly growing and gaining more exposure in both today’s media (specifically, video games and science fiction (SF) screen media, two likely platforms for such work), and the minds of their fans: the so called ‘geek fandom’ that follows this type of media with a passion. The literature review lays the groundwork for this research, following the early days of humanist thought, the birth of ‘anthropocentrism’, and the history of transhuman and posthumanist thought from ancient times through to the modern day. In addition, this thesis tracks the ways in which video games and science fiction scholarship has developed, alongside research methods for both, in order to provide context to the case studies I have created: two for video games, (Xenoblade Chronicles/Xenoblade Chronicles X) and one for SF screen (EX_MACHINA). Empirically, this thesis is triangulated with developer interviews and comments, together with the fan culture study, which provides the base for the primary research. This includes interviews with ‘lay’ fans and experts in various fields alike, which allowed for a great sample diversity. In fact, it is from the latter that the three key themes for this work emerge: ‘body’, ‘identity’ and ‘power’. These themes allow for a unique theoretical framing of trans/posthuman ideology, analysing the depth of popularised themes. Ultimately, with SF as a powerful disseminator of themes and video games as an interactive, responsive medium, these two media types and the fandom surrounding them make an excellent case for the rapid growth of trans/posthuman ideas. Ultimately, this thesis provides a rich triangulated analysis on a constantly shifting and changing scholarship on the current state of popular culture, and especially that of fandom.

description: We report the discovery of ultra-diffuse galaxies (UDGs) in Abell 370 ($z=0.375$). We find 46 UDGs in Abell 370 from the images of the Hubble Frontier Fields (HFF). Most UDGs are low-luminosity red sequence galaxies, while a few of them are blue UDGs. We estimate the abundance of UDGs in Abell 370, $N(\rm UDG)=644\pm104$. Combining these results with those of Abell S1063 ($z=0.348$) and Abell 2744 ($z=0.308$) \citep{Lee17}, we derive a mean radial number density profile of UDGs in the three clusters. The number density profiles of UDGs and bright galaxies show a discrepancy in the central region of the clusters: the profile of UDGs shows a flattening as clustercentric distance decreases, while that of bright galaxies shows a continuous increase. This implies that UDGs are prone to disruption in the central region of the clusters. The relation between the abundance of UDGs and virial masses of their host systems is described by a power-law with an index nearly one: $N({\rm UDG})\propto M_{200}^{0.99\pm0.05}$ for $M_{200}>10^{13}~M_{\odot}$. We estimate approximately dynamical masses of UDGs using the fundamental manifold method, and find that most UDGs have dwarf-like masses $(M_{200}<10^{11}$ $M_{\odot})$. This implies that most UDGs have a dwarf-like origin and a small number of them could be failed $L^{*}$ galaxies. These results suggest that multiple origins may contribute to the formation and evolution of UDGs in massive galaxy clusters.

Investigating a Fluctuating-accretion Model for the Spectral-timing Properties of Accreting Black Hole Systems

description: The fluctuating accretion model of Lyubarskii (1997) and its extension by Kotov et al. (2001), seeks to explain the spectral-timing properties of the X-ray variability of accreting black holes in terms of inward-propagating mass accretion fluctuations produced at a broad range of radii. The fluctuations modulate the X-ray emitting region as they move inwards and can produce temporal-frequency-dependent lags between energy bands, and energy-dependent power spectral densities (PSDs) as a result of the different emissivity profiles, which may be expected at different X-ray energies. Here we use a simple numerical implementation to investigate in detail the X-ray spectral-timing properties of the model and their relation to several physically interesting parameters, namely the emissivity profile in different energy bands, the geometrical thickness and viscosity parameter of the accretion flow, the strength of damping on the fluctuations and the temporal coherence (measured by the `quality-factor', Q) of the fluctuations introduced at each radius. We find that a geometrically thick flow with large viscosity parameter is favoured, and confirm that the predicted lags are quite robust to changes in the emissivity profile, and physical parameters of the accretion flow, which may help to explain the similarity of the lag spectra in the low/hard and high/soft states of Cyg X-1. We also demonstrate the model regime where the light curves in different energy bands are highly spectrally coherent. We compare model predictions directly to X-ray data from the Narrow Line Seyfert~1 galaxy NGC 4051 and the BHXRB Cyg X-1 in its high/soft state and show that this general scheme can reproduce simultaneously the time lags and energy-dependence of the PSD.

Engaging Divided Society in the Nation-Building Process: The Case of Government Communication in Malaysia

Publisher: name: University of Leicester
Year: 2020
Subjects: Uncategorized

description: This thesis explores how government engages with a divided society in the context of nation-building. The widely used yet loosely understood concept of ‘engagement’ in the context of government communication is the focus of this thesis. By using Malaysia as the case study, this research investigates how citizens are communicatively constructed in the context of Malaysia’s post-independence nation-building process. This study is significant because research on citizen engagement in Malaysia’s nation-building is limited and studies focusing on the concept of engagement in deeply divided societies are also scarce.Thematic analysis on all eleven national action plan (NAP) documents known as Malaysia Plan (1965-2016) was conducted to enable the pattern of similarities and differences in nation-building and government communication strategies to be identified over time. Semi-structured elite interviews with the elite actors in Malaysia’s federal government were conducted to understand the government’s articulation and operationalisation of engagement in the context of nation-building process.The key findings from the NAPs reveal that the nation-building in Malaysia takes in a form of national identity project. Adopting an elite instrumentalist approach, national unity becomes the focal communicative strategy in the construction of the national identity. The elite interviews on the other hand demonstrate that government actors tend to describe engagement using the notion of dialogic communication. While acknowledging the advancement in communication technologies, government actors emphasise that the face-to-face engagement initiatives with the citizens are of central importance in the nation-building process.This thesis contributes to the studies of government strategic communication in the context of a deeply divided society that has been characterised as "plural society" that is in a state of “stable tension” (Shamsul, 2009). It helps to develop a richer understanding and knowledge of Malaysia’s nation-building process and approach as a modern postcolonial nation.

description: Interoperability in healthcare is a requirement for effective communication between entities, to ensure timely access to up-to-date medical information and knowledge about patients and therefore facilitate consistent patient care. An interoperability bus for healthcare (BIS) is a software and hardware architecture model that facilitates the exchange of health information between different information systems, such as electronic health records (EHR), laboratory information systems (LIS), medication management systems, electronic prescription, among other health care applications. This is commonly based on the Enterprise Service Bus (ESB) middleware software architecture as a solution for three of the four levels of interoperability for health information systems: foundational, structural and semantic.

This type of technological infrastructure is designed to allow communication and data exchange with a principle of technological neutrality, ensuring that healthcare providers have access to the information they need to provide effective patient care, empowering the citizen on the value of your health data to improve traceability and healthcare.

This document contains a practical guide to have a greater understanding of what a Health Interoperability Bus (BIS) is, what its characteristics are and why it is necessary to consider this type of solutions to have a greater impact on the health of populations. of the countries of Latin America and the Caribbean. Likewise, it aims to guide those governments and entities that are developing acquisition processes for this type of solutions, those who are in charge of auditing, transparency of investments for financing and accountability, as well as the end user of health services who directly or indirectly finance health care.

This work studies the optimal control strategy for a pension plan with refund clause of contributions with predetermined interest under constant elasticity of variance (CEV) in a definedcontribution (DC) pension plan. A model which mandates fund managers to refund dead members’ accumulations with predetermined interest to their next of kin during the accumulation phase is considered. Also considered herein are investments in a bank security and stock where the stock market price is driven by the CEV model and the remaining accumulations are equally distributed between the remaining members. Furthermore, the game theoretic approach is use in establishing an optimization problem from the extended Hamilton Jacobi Bellman (HJB) equation which is a non-linear partial differential equation (PDE). Using mean variance utility
function and method of variable separation, explicit solutions of the optimal control strategy and the efficient frontier are obtained. Finally, Numerical simulations and theoretical analysis are used to study the effect of the elasticity parameter β and some other parameters on the optimal control strategy with observations that the elasticity parameter affects the investment strategy of the fund manager significantly. Also, we observed that the optimal control strategy employed by the fund manager is inversely proportional to the risk aversion coefficient, initial fund size, instantaneous volatility and predetermined interest rate but directly proportional to time.

description: Since gaining independence in 1923, Turkey has been going through major transformations, both culturally and economically. This transformation caused changes in the behaviour of Turkish people, including consumer purchase behaviour. The researcher undertook this study to explore consumer preferences between the shopping mall and the traditional bazaar place. The researcher intended to understand the reasons of visiting these places and their choice preferences, and how their emotions affect their choice behaviours. This study was conducted a mixed methods study in a shopping mall and a traditional market place in Ankara, Turkey. For the quantitative survey, 200 people were randomly chosen at different times and different days of the week. For the qualitative data collection, 12 people were chosen randomly. The data were analysed and interpreted based on the age, gender, marital status, income, and education level.Findings indicated that consumers visiting shopping malls and traditional bazaar places were different. The main difference was that the visitors perceived the shopping malls as safe-spaces for socio-cultural interaction, which in turn helped enhance the sense of belonging. It further found that visitors were considering their visit for shops, food court and that they intended to spend time with family and friends. Emotions were of significance and that certain emotions were evoked during their visits. Visitors visiting the shopping malls were satisfied and they were pleased with their experiences, and their perceptions of the quality and the price of products and services were affected because of these positive emotions. Compared to traditional bazaar places where it is more of a pragmatic and practical experience, shopping malls provided a broader satisfaction among visitors.

description: Facing rapid and significant change in the sector, U.S. dairy production trends from 1993-2005 were tracked and performance measures (scale and technical efficiency and returns on assets) were estimated for conventional and pasture-based dairy farms using data from USDA's Agricultural Resource Management Survey. Comparisons of relative economic performance of dairy farms by size and type are made.
title:  Subjectivity and Self-Creation in Jean-Paul Sartre

description: A partire dal quinto decennio del XX secolo, l'opera di Jean-Paul Sartre, un filosofo-scrittore che ha elaborato un'originale teoria filosofica esistenzialista, ha suscitato grande interesse sia per i filosofi che per i lettori di letteratura. Grazie alla scrittura attraente, così come al posto centrale che dà alla libertà individuale e alla soggettività creativa attraverso cui l'uomo può superare situazioni esistenziali vincolanti, l'opera di Jean Paul-Sartre non ha perso la sua attualità nemmeno nel XXI secolo. Il mio articolo intende presentare un frammento della traccia intellettuale concepita da Jean-Paul Sartre come creazione più o meno impegnata, principalmente tra la pubblicazione del romanzo La Nausea in contemporanea con Idee per una teoria delle emozioni e la pubblicazione del saggio L’esistenzialismo è un umanismo. Il messaggio della lezione estetico-filosofica di Sartre è che l'esistenza può essere giustificata dall'arte e dalla creazione. In Sartre, la scrittura ha la precisa funzione di porre fine alla nausea mettendo in relazione l'"Essere-per-sé" con l'"Essere-in-sé" e forse anche con l'"Essere-per-gli-Altri" nel testo conservato nella memoria immediata e ansiosa dell'estraneità della propria persona e posto sulla pagina. Il fenomeno patologico chiamato "nausea" significa, tra le altre interpretazioni, il gusto (e in definitiva anche il sapore) o il sentimento della fatticità e contingenza dell'esistenza.

description: The freeze out of particles from a layer of finite thickness is discussed in a phenomenological kinetic model. The proposed model, based on the Modified Boltzman Transport Equation, is Lorentz invariant and can be applied equally well for the freeze out layers with space-like and time-like normal vectors. It leads to non-equilibrated post freeze out distributions. The dependence of the resulting distribution on the thickness of the layer is presented and discussed for a space-like freeze out scenario.

description: Jersey Fresh retailers and wholesalers feel that the logos are effective in increasing sales. Most feel that the popularity of the logo among the consumers is moderate. The results of this study indicate that the promotional aspect of the program was more popular among all the participant groups than the quality control aspect. The mail surveys indicated that a greater number of participants were aware of and were using the promotional logo than the quality grading logo. Only a fifth of the wholesalers who were aware of the quality-grading program were enrolled in the program. The results also indicated that participants who thought that consumer awareness of the program was high were more likely to be enrolled. This study also illustrates that most retailers and wholesalers participating in the program prefer the colorful Jersey Fresh Promotional Logo (Logo A in Appendix) and would like to have one common logo for both promotion and quality grading. Retailers who believed that consumers were highly aware of Jersey Fresh were found more likely to have been using the Jersey Fresh Logos. Retailers who used other logos to identify their fresh produce were found more likely to use Jersey Fresh Logos in the future. Willingness to use Jersey Fresh Logos in the future was found to be lower among retailers who sell more than 75 percent of their sales in retailing. Willingness to use the logos was also found to decrease with the age of retailers. Retailers with outlets in the urban areas of New Jersey and with retail outlets that were open for more than 8 months during the year were more likely to be use Jersey Fresh Logos. Farmers with more experience in retailing produce were more likely to use the logos. Wholesalers who used other logos, who advertised through signs and used word of mouth to identify their produce were more found more likely to use the Jersey Fresh Logos. Wholesalers who sell more than 75 percent of their annual trade to other wholesale buyers, were found less likely to use the logos and less willing to use the logos in the future.
Perturbative renormalization of the first moment of structure functions for domain-wall QCD

description: Using the domain-wall formulation of lattice fermions, we have computed the one-loop renormalization factors of one-link operators which measure the first nontrivial moment of the unpolarized, polarized and transversity structure functions, in the flavor nonsinglet sector. The knowledge of these factors is necessary in order to extract physical numbers from domain-wall Monte Carlo simulations of parton distributions. We have automated the perturbative calculations by developing suitable FORM codes. The results show that in many instances the total renormalization factors are almost equal to one, and that hence the corresponding operators are, for the appropriate values of the Dirac mass $M$ and the coupling $g_0$, practically unrenormalized.

description: Compressive plasma turbulence is investigated at sub-ion scales in the solar wind using both the Fast Plasma Investigation (FPI) instrument on the Magnetospheric MultiScale mission (MMS), as well as using calibrated spacecraft potential data from the Spin Plane Double Probe (SDP) instrument. The data from FPI allow a measurement down to the sub-ion scale region ($f_{sc}\gtrsim 1$ Hz) to be investigated before the instrumental noise becomes significant at a spacecraft frame frequency of $f_{sc}\approx 3$Hz, whereas calibrated spacecraft potential allows a measurement up to $f_{sc}\approx 40$Hz. In this work, we give a detailed description of density estimation in the solar wind using the spacecraft potential measurement from the SDP instrument on MMS. Several intervals of solar wind plasma have been processed using the methodology described which are made available. One of the intervals is investigated in more detail and the power spectral density of the compressive fluctuations is measured from the inertial range to the sub-ion range. The morphology of the density spectra can be explained by either a cascade of Alfvén waves and slow waves at large scales and kinetic Alfvén waves at sub-ion scales, or more generally by the Hall effect. Using electric field measurements the two hypotheses are discussed.
