description: Die vorliegende Arbeit versucht durch die bewusste Aktivierungder menschlichen Sinne die Verbindung zwischen Mensch und Zuhause zu stärken. Das Hauptaugenmerk wird dabei auf den Geruchs- und Geschmackssinn gelegt. Die Hypothese ist, dass ein bewusstes Auseinandersetzen mit der baulichen Substanz die Verbindung zwischen Bewohnenden und Bewohntem (‘the dwellers and the dwelling’) stärkt und im besten Fall das Wohlbefinden zu Hause steigert. Dem Zuhause wird eine Identität zugeschrieben, die es zu respektieren gilt. Durch die Projektion der menschlichen Sinne auf die gebaute Umwelt findet ein Umdenken statt, welches das Zuhause zum Subjekt werden lässt. Die zum Genuss dienende Aufbereitung und teilweise zumutbare Verzehrung des Zuhauses, verhilft außerdem den Bewohnenden sich näher mit ihrer gebauten Umwelt auseinanderzusetzen, fördert den Wissenszuwachs im Umgang mit Baustoffen und lässt Mensch und Zuhause eine gemeinsame Sprache sprechen. Ein (konzeptionelles) Architektur-Rezeptbuch rundet die Arbeit ab.
description: This thesis tries to strengthen the connection between resident and home by consciously using the human senses. The main focus lies on the senses of smell and taste. The hypothesis is that a conscious engagement with the structural substance strengthens the connection between the dwellers and the dwelling and, in the best case, increases well-being at home. The place we call home is assigned an identity that must be respected. By projecting the human senses onto the built environment, a rethinking is taking place that allows the home to be seen as a subject. The preparation of home in order to consume it with the sense of taste encourages the residents to deal more closely with their built environment, promotes knowledge gain in handling specific materials and allows residents and homes to speak a common language. A (conceptual) architecture recipe book completes the work.

description: Most wildfires are started by humans, however, geographic variation of potential ignition sources is not often explicitly accounted for in wildfire simulation modelling or risk assessments. In this study, we investigated how patterns of human and lightning ignitions can influence modelled fire simulations and demonstrate how these data can be used to assess post-fire flooding and sediment transport. We used historical ignition data (1992–2015) to characterize ignition patterns for thirteen mountain ranges in southern Arizona, United States, and developed FlamMap burn probability (BP) models for three scenarios: human ignition, lightning ignition, and random ignition. We then developed a watershed-scale case study assessing the impacts of ignition scenarios on post-fire hydrology using the KINEROS2 model that simulates runoff and erosion. BP models illustrated considerable differences in landscape fire risk between the three ignition scenarios. Results from the watershed model indicate the greatest impacts from the post-fire human ignition scenario, with a 10-fold increase in sediment discharge and four-fold increase in peak flow compared to pre-fire conditions. Our results show that consideration of ignition source and location is important for assessing fire risk, and our modelling approach provides a planning mechanism to identify locations most at risk to fire-induced flood hazards, where prevention and mitigation activities can be focused.

description: The ion-ion interactions become exponentially screened for ions confined in ultranarrow metallic pores. To study the phase behaviour of an assembly of such ions, called a superionic liquid, we develop a statistical theory formulated on bipartite lattices, which allows an analytical solution within the Bethe-lattice approach. Our solution predicts the existence of ordered and disordered phases in which ions form a crystal-like structure and a homogeneous mixture, respectively. The transition between these two phases can potentially be first or second order, depending on the ion diameter, degree of confinement and pore ionophobicity. We supplement our analytical results by three-dimensional off-lattice Monte Carlo simulations of an ionic liquid in slit nanopores. The simulations predict formation of ionic clusters and ordered snake-like patterns, leading to characteristic close-standing peaks in the cation-cation and anion-anion radial distribution functions.

description: We present encube $-$ a qualitative, quantitative and comparative visualisation and analysis system, with application to high-resolution, immersive three-dimensional environments and desktop displays. encube extends previous comparative visualisation systems by considering: 1) the integration of comparative visualisation and analysis into a unified system; 2) the documentation of the discovery process; and 3) an approach that enables scientists to continue the research process once back at their desktop. Our solution enables tablets, smartphones or laptops to be used as interaction units for manipulating, organising, and querying data. We highlight the modularity of encube, allowing additional functionalities to be included as required. Additionally, our approach supports a high level of collaboration within the physical environment. We show how our implementation of encube operates in a large-scale, hybrid visualisation and supercomputing environment using the CAVE2 at Monash University, and on a local desktop, making it a versatile solution. We discuss how our approach can help accelerate the discovery rate in a variety of research scenarios.

description: Construction inspection and building occupancy permit services are the two significant instruments that enable the building permit and control authority to check the quality and the right purposes of the buildings to secure society's safety. Therefore, this study Evaluates the Construction Inspection and Building Occupancy Permit Issuance Services in Addis Ababa at central (Municipality) Bole and Lideta Sub-cities. The paper addresses the efficiency and effectiveness of the services, service quality, customer satisfaction, major challenges, impacts, and measures that should be taken. Both qualitative and quantitative approaches were used. Study sites were selected purposively, and out of 1032 service seekers, 300 were selected as samples. In addition, 24 experts and three officials were respondents and collected data from them through questionnaires, interviews, focus group discussion, and observation. The data were analyzed quantitatively and qualitatively and also presented in text, figures, and table forms. The study found that the performance of the offices was not effective and efficient; the negative SERVQUAL result implies that the service lacks quality, and the majority of the service seekers satisfied moderately. Long appointment and absenteeism, knowledge gap, inadequate office equipment, corruption, and rent-seeking were some of the challenges which had different impacts like improper building construction inspection, a huge amount of fine, and buildings under construction damage their surroundings. Stakeholders' participation, capacity building, and the application of the SERVQUAL and Common Measurement Tools are the recommendations as remedial actions to alleviate the problems.

description: Floods are the most common sort of natural disaster that occurs when a body of water overflows and submerges on dry terrain. Several regions in Sidoarjo District, East Java such as Kedungbanteng and Banjarasri Village, have experienced floods with varying heights since 2018 due to heavy rainfall in the areas. According to the Meteorological, Climatological, and Geophysical Agency (BMKG), rainfall intensity in these areas reach 100 mm/day. Furthermore, the physical environment in both areas shows land subsidence that causes a change in the flow pattern, which triggers its occurrence. This research incorporated different small baseline techniques of InSAR time series analysis and used GPS measurement to evaluate and monitor the land subsidence in both areas. The reseachers used Sentinel-1 SAR data both from ascending and descending for the period between 2017 and 2021. The results showed significant subsidence value by up to −200 mm/year both in Kedungbanteng and Banjarasri Village, and GPS observation also confirmed approximately −3.2 cm of subsidence value during 2 months of sampling observations. Using the neural network analysis, the reseachers predicted the time series displacement for one year and showed that a continuous trend of deformation still existed.

description: For dynamical systems with the shadowing property, we provide a method of approximation of invariant measures by ergodic measures supported on odometers and their almost 1-1 extensions. For a topologically transitive system with the shadowing property, we show that ergodic measures supported on odometers are dense in the space of invariant measures, and then ergodic measures are generic in the space of invariant measures. We also show that for every $c\geq 0$ and $\varepsilon>0$ the collection of ergodic measures (supported on almost 1-1 extensions of odometers) with entropy between $c$ and $c + \varepsilon$ is dense in the space of invariant measures with entropy at least $c$. Moreover, if in addition the entropy function is upper semi-continuous, then for every $c\geq 0$ ergodic measures with entropy $c$ are generic in the space of invariant measures with entropy at least $c$.

Publisher: name: Freie Universität Berlin
Year: 2022
Subjects: subject: meaning in human language
subject: 400 Sprache::410 Linguistik::410 Linguistik

description: This book provides an introduction to the study of meaning in human language, from a linguistic perspective. It covers a fairly broad range of topics, including lexical semantics, compositional semantics, and pragmatics. The chapters are organized into six units: (1) Foundational concepts; (2) Word meanings; (3) Implicature (including indirect speech acts); (4) Compositional semantics; (5) Modals, conditionals, and causation; (6) Tense & aspect. Most of the chapters include exercises which can be used for class discussion and/or homework assignments, and each chapter contains references for additional reading on the topics covered. As the title indicates, this book is truly an introduction: it provides a solid foundation which will prepare students to take more advanced and specialized courses in semantics and/or pragmatics. It is also intended as a reference for fieldworkers doing primary research on under-documented languages, to help them write grammatical descriptions that deal carefully and clearly with semantic issues. The approach adopted here is largely descriptive and non-formal (or, in some places, semi-formal), although some basic logical notation is introduced. The book is written at level which should be appropriate for advanced undergraduate or beginning graduate students. It presupposes some previous coursework in linguistics, but does not presuppose any background in formal logic or set theory.
Effectiveness of One Stop Service Centers in Micro and Small Scale Enterprise Development Sector: The Case of Selected Woreda in Addis-Ketema Sub-city, Addis Ababa
Creators: name: Zakie, Zewdie
Publisher: name: African Journal of Leadership and Development
Year: 2018

description: The purpose of study was assessing the effectiveness of “One stop service centers” in-service delivery to the customers of Micro and Small Scale Enterprise Development sector in five-selected woreda of Addis-Ketema sub-city. The study was guided by one-stop shop and service Reception, Processing and Returning (RPR) models. To this end, descriptive survey research design was employed and 99 enterprise managers were selected using random sampling techniques. For qualitative data collection, 20 enterprise managers who were not participated in filling questionnaire and 16 operators from female owned enterprises were selected purposively. Quantitative data analysis was done using mean values computed from the 5-likert scale. Triangulation of findings from both quantitative and qualitative sources was done at the interpretation phase. The study results indicate that the centers have no net effect of giving the customers the opportunity to get multiple interrelated services in one place so as to ensure better accessibility. The study identified issues like extractive service delivery set ups, lack of well-trained and adequate number of staffs, lack office facilities; inefficient case handling and management mechanisms; and lack of feedback and solicitation mechanisms as factors affecting the effectiveness of the centers under study settings. Thus, this study recommends that the centers need to be re-designed to avail all services at one roof in such a way that case reception, processing and returning will be at one place. The study further suggests that the sector needs to give due attention to human resource development and equipping the centers with office facilities.

description: This book brings together papers that discuss social and structural aspects of language contact and language change. Several papers look at the relevance of historical documents to determine the linguistic nature of early contact varieties, while others investigate the specific processes of contact-induced change that were involved in the emergence and development of these languages. A third set of papers look at how new datasets and greater sensitivity to social issues can help to (re)assess persistent theoretical and empirical questions as well as help to open up new avenues of research. In particular they highlight the heterogeneity of contemporary language practices and attitudes often obscured in sociolinguistic research. The contributions all focus on language variation and change but investigate it from a variety of disciplinary and empirical perspectives and cover a range of linguistic contexts.

description: We report on the first singly-resonant (SR), synchronously pumped optical parametric oscillator (OPO) based on orientation-patterned gallium arsenide (OP-GaAs). Together with a doubly resonant (DR) degenerate OPO based on the same OP-GaAs material, the output spectra cover 3 to 6 $μ$m within ~3 dB of relative power. The DR-OPO has the highest output power reported to date from a femtosecond, synchronously pumped OPO based on OP-GaAs. We discovered strong three photon absorption with a coefficient of 0.35 ${\pm}$ 0.06 cm${^3}$/GW${^2}$ for our OP-GaAs sample, which limits the output power of these OPOs as mid-IR light sources. We present a detailed study of the three photon loss on the performance of both the SR and DR-OPOs, and compare them to those without this loss mechanism.

description: With advancements in computational technology, data assimilation techniques, high-resolution remote sensing, and complex climate models, numerous precipitation products are available with different spatiotemporal resolutions; however, their evaluation, especially in the Himalayan region, is unexplored. Therefore, this study attempts to assess four sources (gridded observation dataset, reanalysis, satellite, and numerical weather prediction models) of precipitation through hydrological modelling for the catastrophic 2013 floods of Uttarakhand, India. The Upper Ganga Basin located in Western Himalayas is selected as the study area consisting of Alaknanda and Bhagirathi streams in the eastern and western parts. The Hydrologic Engineering Center’s Hydrologic Modeling System (HEC-HMS) is employed for rainfall-runoff modelling. The rainfall from IMD, ERA-5, GPM-IMERG-Final, and WRF model outputs are forced into the calibrated HEC-HMS model for assessing their performance in hydrological simulations. The correlation coefficient of IMD, ERA-5, GPM-IMERG-Final, and WRF simulations with respect to the observed flow is 0.89, 0.88, 0.55, and 0.89, respectively, whereas their corresponding Modified Kling-Gupta Efficiency (KGE) is 0.66, 0.72, 0.48, and 0.71. Flash flood prioritization of the sub-watersheds based on morphometric characteristics suggests that the Alaknanda basin is relatively more vulnerable to flash floods due to their elongated nature, highest relative relief, and high mean slope.

description: We measured the minimum inhibitory concentration (MIC) of the antimicrobial peptide pexiganan acting on Escherichia coli, and report an intrinsic variability in such measurements. These results led to a detailed study of the effect of pexiganan on the growth curve of E. coli, using a plate reader and manual plating (i.e. time-kill curves). The measured growth curves, together with single-cell observations and peptide depletion assays, suggested that addition of a sub-MIC concentration of pexiganan to a population of this bacterium killed a fraction of the cells, reducing peptide activity during the process, while leaving the remaining cells unaffected. This pharmacodynamic hypothesis suggests a considerable inoculum effect, which we quantified. Our results cast doubt on the use of the MIC as 'a measure of the concentration needed for peptide action' and show how 'coarse-grained' studies at the population level give vital information for the correct planning and interpretation of MIC measurements.

description: This study describes the spectral emissive character of silicate and carbonate minerals of aeolian deposits and maps the deposits and sand encroachments that occurred in and around the site 5/6 of Qatar Fertilizer Company (QAFCO), Qatar using thermal infrared (TIR) bands of ASTER. The results of studies show that the quartz and unaltered silicates have spectral features between 8.12 and 9.27 µm, and the calcite and dolomite have emissivity minima near 11.4 and 11.2 µm, respectively. The mapping of deposits, dunes, and carbonate formations using the bands, and quartz index (QI), and carbonate index (CI) displayed their occurrence, distribution, and direction of sand movement from NW to SE. The sand encroachment was mapped using high spatial resolution satellite data of WorldView-2. The study of physicochemical characteristics of field samples showed the occurrence of sand grains up to 99.81% and the XRD and geochemical analyses represented the presence of quartz, calcite, dolomite, albite, and halite minerals in the deposits. In addition, the bacterial strains isolated from the samples indicated high urease activity leading to precipitation of carbonate minerals via microbially induced calcite precipitation (MICP) processes, and demonstrated high potential for utilization for sand stabilization of the QAFCO site.

description: Populations in coastal areas are vulnerable to chronic exposure to potentially toxic elements (PTEs) from aquatic ecosystems. In this study, we estimated the health risks from Cd, Cr, Fe, and Pb exposure in river water, sediments, and edible aquatic biota (Anadara granosa and Chanos chanos). Human daily intake was determined by an interview process with 287 respondents that were selected by proportional cluster random sampling. The cumulative probability value for total risk exceeded the acceptable limit value, indicating that adverse health impacts from PTE exposure may occur in the Pangkep coastal population. The sensitivity analysis showed that exposure duration and Cr concentrations are the factors with the greatest influence in a recreational exposure scenario, whereas the frequency of exposure to shellfish and milkfish is the most influential factor for health risks in a residential scenario. Thus, reducing Cr concentrations in river water, restricting swimming duration, and limiting the frequency of shellfish and milkfish consumption are required to mitigate health risks in the future.
title: Brownout modeling
Creators: name: Rovere, Federico
Publisher: name: University of Glasgow
Year: 2023

description: The thesis compares different computational approaches for simulate brownout clouds. Brownout relates to blinding dust clouds stirred up by the helicopter rotor downwash during near-ground flight. This causes significant flight safety risks, including ground obstacle collisions and dynamic rollover due to sloped and uneven terrain. Operating helicopters in brownout conditions is very dangerous and has claimed many lives. Due to the complexity of these phenomena, and the safety issues they may generate, brownout has been studied using different approaches, both numerical and experimental. In terms of the computational investigations: brownout works may be divided into the two approaches used to predict the dust cloud: Lagrangian and Eulerian. A direct comparison of the two models s is presented in the same framework, to define the best practice for brownout predictions. The present work involved the development of a Lagrangian particle tracking algorithm and an Eulerian model in the HMB3 (Helicopter Multi Block) framework. Brownout clouds obtained with these models are compared with experimental results and between them. Results show that even if in proximity to a rotor, the accuracy of the two models is comparable, further from it the Lagrangian approach is more accurate than modelling based on the Eulerian approach. Furthermore, the two models are compared in terms of computational efficiency, and results show how Eulerian is a better model to predict brownout, due to its intrinsic abilities not to being affected in its computational efficiency by the amount of particles. In addition, brownout clouds are compared in terms of size at different rotor configurations. Results show how rotors with higher thrust coefficient are able to generate the more dangerous scenarios, generating bigger clouds than rotors operating at lower thrust coefficients. The presence of the fuselage has also been studied, comparing cases with and without it. The thesis includes more safety aspects, including risks posed to ground personnel and nearby structures due to the strong outflow generated by hovering and taxiing rotorcraft. In this work, an analysis of safety operations is performed in terms of forces that ground personnel may suffer due to strong rotor outflows. Force distribution over the human body and total force are computed from the resolved flowfield around a rotor. Different single rotor configurations have been taken into account, and in all cases considered, the whole area around the rotor can be considered safe according to military-based thresholds.

description: Inherent loss is always to be avoided in generating single photons or biphotons, but interestingly it provides opportunities for manipulating the photon wave packet. In this paper we show how inherent loss in parametric down-conversion can be employed to tailor the wave packets of single photons and biphotons. As an example, we propose a scheme to realize a single photon in a single cycle using inherent loss. Our work has potential applications in quantum communication, quantum computation, and quantum interface.

description: Food insecurity remains a severe threat for people living in least developed and conflict-affected settings. Development organizations frequently apply small-scale agricultural support to strengthen food security in such settings. However, impact evaluation is challenging in these fragile contexts. Thus, rigorous evidence remains scarce and inconclusive. Applying a difference-in-differences approach together with propensity score matching on household survey data from South Sudan, I test the impact of small-scale agricultural interventions coupled with a cash transfer on food security outcomes in a least developed setting highly affected by conflict. My findings emphasize that after one year, the treatment significantly improved household food security measured by the Minimum Dietary Diversity Score. On average, treatment households consumed one additional food type per day due to the support. However, in absence of the cash component, the agricultural intervention did not improve dietary diversity substantially. Other food security measures do not show significant impacts of the combined intervention. The results indicate that the support was effective in maintaining a constant harvest output while control households faced a clear declining trend. Covariate adverse shocks like floods and droughts do not show heterogeneous treatment effects while idiosyncratic shocks such as a disease of the household head inhibit the positive programme impact on dietary diversity. The results imply that small-scale agricultural interventions contribute to diversify household diets in least developed and conflict-affected settings in the short-run.
Linear dynamics of classical spin as Möbius transformation

description: Although the overwhelming majority of natural processes occurs far from the equilibrium, general theoretical approaches to non-equilibrium phase transitions remain scarce. Recent breakthroughs introducing description of open dissipative systems in terms of non-Hermitian quantum mechanics allowed to identify a class of non-equilibrium phase transitions associated with the loss of combined parity (reflection) and time-reversal symmetries. Here we report that time evolution of a single classical spin (e.g. monodomain ferromagnet) governed by the Landau-Lifshitz-Gilbert-Slonczewski equation in absence of higher-order anisotropy terms is described by a Möbius transformation in complex stereographic coordinates. We identify the \textit{parity-time} symmetry-breaking phase transition occurring in spin-transfer torque-driven linear spin systems as a transition between hyperbolic and loxodromic classes of Möbius transformations, with the critical point of the transition corresponding to the parabolic transformation. This establishes the understanding of non-equilibrium phase transitions as topological transitions in configuration space.

description: Ultraluminous X-ray sources (ULXs) are bright extragalactic sources with X-ray luminosities above 10^39 erg/s powered by accretion onto compact objects. According to the first studies performed with XMM-Newton ULXs seemed to be excellent candidates to host intermediate-mass black holes (10^2-4 solar masses). However, in the last years the interpretation of super-Eddington accretion onto stellar-mass black holes or neutron stars for most ULXs has gained a strong consensus. One critical missing piece to confirm the super-Eddington scenario was the direct detection of the massive, radiatively-driven winds expected as atomic emission/absorption lines in ULX spectra. The first evidence for winds was found as residuals in the soft X-ray spectra of ULXs. Most recently we have been able to resolve these residuals into rest-frame emission and blueshifted (~0.2c) absorption lines arising from highly ionized gas in the deep high-resolution XMM-Newton spectra of two ultraluminous X-ray sources. The compact object is therefore surrounded by powerful ultrafast winds as predicted by models of hyper-Eddington accretion. Here we discuss the relevance of these discoveries and the importance of further, deep, XMM-Newton observations of powerful winds in many other ultraluminous X-ray sources to estimate the energetics of the wind, the geometry of the system, and the masses of the central accretors.

description: Experiments show that spike-triggered stimulation performed with Bidirectional Brain-Computer-Interfaces (BBCI) can artificially strengthen connections between separate neural sites in motor cortex (MC). What are the neuronal mechanisms responsible for these changes and how does targeted stimulation by a BBCI shape population-level synaptic connectivity? The present work describes a recurrent neural network model with probabilistic spiking mechanisms and plastic synapses capable of capturing both neural and synaptic activity statistics relevant to BBCI conditioning protocols. When spikes from a neuron recorded at one MC site trigger stimuli at a second target site after a fixed delay, the connections between sites are strengthened for spike-stimulus delays consistent with experimentally derived spike time dependent plasticity (STDP) rules. However, the relationship between STDP mechanisms at the level of networks, and their modification with neural implants remains poorly understood. Using our model, we successfully reproduces key experimental results and use analytical derivations, along with novel experimental data. We then derive optimal operational regimes for BBCIs, and formulate predictions concerning the efficacy of spike-triggered stimulation in different regimes of cortical activity.

description: Drawing from the optimal transport theory adapted to the relativistic setting we formulate the principle of a causal flow of probability and apply it in the wave packet formalism. We demonstrate that whereas the Dirac system is causal, the relativistic-Schrödinger Hamiltonian impels a superluminal evolution of probabilities. We quantify the causality breakdown in the latter system and argue that, in contrast to the popular viewpoint, it is not related to the localisation properties of the states.

On DP-coloring of graphs and multigraphs

description: While solving a question on list coloring of planar graphs, Dvořák and Postle introduced the new notion of DP-coloring (they called it correspondence coloring). A DP-coloring of a graph $G$ reduces the problem of finding a coloring of $G$ from a given list $L$ to the problem of finding a "large" independent set in an auxiliary graph $H(G,L)$ with vertex set $\{(v,c)\,: \, v\in V(G) \text{ and } {c\in L(v)} \}$. It is similar to the old reduction by Plesnevič and Vizing of the $k$-coloring problem to the problem of finding an independent set of size $|V(G)|$ in the Cartesian product $G\square K_k$. Some properties of the DP-chromatic number $χ_{DP}(G)$ resemble the properties of the list chromatic number $χ_{\ell}(G)$ but some differ quite a lot. It is always the case that $χ_{DP}(G)\geq χ_{\ell}(G)$. The goal of this note is to introduce DP-colorings for multigraphs and to prove for them an analog of the result of Borodin and Erdős, Rubin, and Taylor characterizing the multigraphs that do not admit DP-colorings from some DP-degree-lists. This characterization yields an analog of Gallai's Theorem on the minimum number of edges in $n$-vertex graphs critical with respect to DP-coloring.

Critical assessment of von Mises distribution and an infinite series ansatz for self-propelled particles

description: We consider a Vicsek model of self-propelled particles with bounded confidence, where each particle interacts only with neighbors that have a similar direction. Depending on parameters, the system exhibits a continuous or discontinuous polar phase transition from the isotropic phase to a phase with a preferred direction. In a recent paper [1] the von Mises distribution was proposed as an ansatz for polar ordering. In the present system the time evolution of the angular distribution can be solved in Fourier space. We compare the results of the Fourier analysis with the ones obtained by using the von Mises distribution ansatz. In the latter case the qualitative behavior of the system is recovered correctly. However, quantitatively there are serious deviations. We introduce an extended von Mises distribution ansatz such that a second term takes care of the next two Fourier modes. With the extended ansatz we find much better quantitative agreement. As an alternative approach we also use a Gaussian and a geometric series ansatz in Fourier space. The geometric series ansatz is analytically handable but fails for very weak noise, the Gaussian ansatz yields better results but it is not analytically treatable.

description: We present high-resolution, long-slit spectroscopic observations of two planetary nebulae with [WC] central stars located near the galactic bulge, M 1-32 and M 3-15. The observations were obtained with the 2.1-m telescope at the Observatorio Astronómico Nacional, San Pedro Mártir. M 1-32 shows wide wings on the base of its emission lines and M 3-15 has two very faint high-velocity knots. In order to model both PNe we built a three-dimensional model consisting of a jet interacting with an equatorially concentrated slow wind, emulating the presence of a dense torus, using the Yguazú hydrodynamical code. From our hydrodynamical models, we obtained position-velocity (PV) diagrams in the [N II]$λ$6583 line for comparison with the observations. We find that the spectral characteristics of M 1-32 and M 3-15 can be explained with the same physical model -a jet moving inside an AGB wind- using different parameters (physical conditions and position angles of the jet). In agreement with our model and observations, these objects contain a dense torus seeing pole-on and a bipolar jet escaping thorough the poles. Then we propose to classify this kind of objects as spectroscopic bipolar nebulae, although they have been classified morphologically as compact, round, or elliptical nebulae or with "close collimated lobes".

description: We selected 82 u-band variable objects based on the u-band photometry data from SCUSS and SDSS, in the field of LAMOST Complete Spectroscopic Survey of Pointing Area at Southern Galactic Cap. The magnitude variation of the targets is restricted to larger than 0.2 mag and limiting magnitude down to 19.0 mag in u-band. According to the spectra from LAMOST, there are 11 quasars with red-shift between 0.4 and 1.8, 60 variable stars and 11 unidentified targets. The variable stars include one active M-dwarf with a series of Balmer emission lines, seven Horizontal Branch stars containing six RR Lyrae stars matching with SIMBAD, and one giant, one AGB star and two RR Lyrae candidates by different colour selections. All these variable stars mainly locate near the main sequence in the g-r verse u-g diagram. The quasars are well distinguished from stars by both u-g colour and variation in u-band.
