description: The very high unemployment rate and the very high political problems in the country lead to this work. The main thematic of this master thesis is "The prerequisites and needs for the automotive supplier industry to become established in Bosnia and Herzegovina". This work contains information about the actual situation in Bosnia and Herzegovina and the actual automotive supplier industry in Bosnia and Herzegovina. Also a historical overview of the automotive industry in Bosnia and Herzegovina is provided. The work shows the actual problems and gives ideas and plans to overcome these problems. The objective of this work is to define preconditions and proposals, together with solutions,for Bosnia and Herzegovina to be able to establish a automotive supplier industry in the country and to gain more investors in that area. There will be defined a set of criterions which are relevant for investors for there decisions. It will be shown how these criterions must look like and how should they be fulfilled by the country of Bosnia and Herzegovina. We will see that the political situation and the corruption are the most problematic things which block the country to have more prosperity in the country

description: An important action in the strategy for reducing greenhouse gas (GHG) emissions at the national level can be the promotion of changes in eating habits, by changing the profile of meat species and quantities of meat in the food rations of the population. The aim of this study was to assess the possibility of reducing GHG emissions by different diet scenarios in Poland. The following types of diets were distinguished: average, vegan, vegetarian lacto-ovo, carnivore, poultry meat, demitarian, and reduced energy value. By analyzing the composition of the diets and GHG emission related to the food production per 1 kcal of different products, emissions of these gases on a national scale for different diet scenarios were calculated. The study results indicate that the modification of food preferences towards diets – vegan, poultry meat and demitarian – allows GHG emissions to be markedly reduced compared to the average diet. / Synopsis. Ważnym działaniem w strategii ograniczania emisji gazów cieplarnianych (GHG) na poziomie krajowym może być promowanie zmian nawyków żywieniowych przez zmianę profilu gatunkowego mięs i ilości mięsa w racjach pokarmowych ludności. Celem badań była ocena możliwości redukcji emisji GHG za pomocą różnych scenariuszy diet w Polsce. Wyróżniono następujące typy diet: przeciętną, wegańską, wegetariańską lakto-owo, mięsożercy, mięsną drobiową, demitarian i o obniżonej wartości kalorycznej. Analizując skład diet oraz emisję GHG przy produkcji żywności w przeliczeniu na 1 kcal różnych produktów obliczono wielkość emisji tych gazów w skali kraju dla różnych scenariuszy diet. Wyniki badań wskazują, że modyfikacja preferencji żywieniowych w kierunku diet: wegańskiej, mięsnej drobiowej oraz demitarian pozwala osiągnąć wyraźne zmniejszenie poziomu emisji GHG w stosunku do przeciętnej diety.

description: The aim of this master thesis consists in recognizing the challenges of putting the architectural design process into a system-oriented model. While project management has become a useful in order to assure the successful progression of a project, it is very difficult to apply the same strategies than for a production project, for example, in a design domain; in architecture. While the success of a project in a scientific domain can easily be measured, it is not evident to assess the quality of a design. An analogy is established between the architectural design process and a system-oriented model, which transforms given inputs into outputs. In the first part of this master thesis the architectural design process - or system-architecture - is analysed and two different concepts are presented: the linear architectural design process and the integrated design process. The two processes are considering the architectural design as starting with the first sketch and ending with the built construction. Not only the processes will be presented but also the available tools, like BIM, which facilitate the implementation of a system-architecture. In the second part, the drawbacks, challenges and advantages of the previous described concepts of organising the architectural design process and using the tools (software and platforms) are analysed. The conclusion does not give the optimum solution how a strategic concept can be established in order to improve the organisation of an architectural process. The conclusion rather shows the origins of the difficulties and pinpoints an important issue: Architecture is always developed by humans for humans.

description: In recently developed non-fullerene acceptor (NFA) based organic solar cells (OSCs), both the donor and acceptor parts can be excited by absorbing light photons. Therefore, both electron transfer and hole transfer channels could occur at the donor/acceptor interface for generating free charge carriers in NFA based OSCs. However, in many molecular and DNA systems, recent studies revealed the high charge transfer (CT) efficiency cannot be reasonably explained by a CT model with only highest occupied molecular orbitals (HOMOs) and lowest unoccupied molecular orbitals (LUMOs) of donor and acceptor molecules. In this work, taking an example of a full-polymer blend consisting of benzodithiophenealt-benzotriazole copolymers (J51) as donor and naphthalene diimide-bithiophene (N2200) as acceptor, in which the ultrafast hole transfer has been recently reported, we investigate its CT process and examine the different roles of various frontier molecular orbitals. Through a joint study of quantum mechanics electronic structure calculation and nonadiabatic dynamics simulation, we find the hole transfer between HOMOs of J51 and N2200 can hardly happen but the hole transfer from HOMO of N2200 to HOMO-1 of J51 is much more efficient. This points out the underlying importance of deep hole channel in CT process and indicates that including frontier molecular orbitals (FMOs) other than HOMOs and LUMOs is highly necessary to build a robust physical model for studying CT process in molecular optoelectronic materials.

description: The study presents the application of DEA analysis, particularly the SE-CCR model, to construct efficiency rankings of EU farms specializing in milk production. The analysis was based on statistical data published by FADN. Technical efficiency of average dairy farms in individual EU countries was determined for three types of their products using four basic factors of production. The analysis showed that production of Polish dairy farms in 2013 was efficient; nevertheless, these farms ranked only 18th in the ranking of milk production efficiency among 23 EU countries. / Synopsis.

description: Soybean is one of the oldest and most valuable crop plants grown in the world. It owes popularity to its use-value as well as its positive influence on soil and successive plants. The aim of this article is to characterize the economic importance of soybean as well as determine selected factors influencing the possibility of expanding its production in Poland. The share of soybean and its processed products was characterized in comparison with production, exports and use of oil seeds, meal and vegetable oils in the world and in Poland. One of the main factors influencing commencement of a given crop production is how production costs (among others) affect crop profitability. Therefore, in order to show the production profitability, soybean production costs were presented in the selected farms of main producers and soybean exporters in the world as well as Poland. / Synopsis. Soja jest jedną z najstarszych oraz najbardziej wartościowych roślin uprawnych na świecie. Swoją popularność zawdzięcza wysokiej wartości użytkowej nasion jak również korzystnemu wpływowi na glebę i rośliny następcze. Celem artykułu była charakterystyka znaczenia gospodarczego soi oraz wskazanie wybranych czynników decydujących o możliwości rozszerzenia jej produkcji w Polsce. Scharakteryzowano udział soi i produktów jej przerobu na tle produkcji, eksportu oraz zużycia surowców i śrut oleistych oraz olejów roślinnych na świecie oraz w Polsce. Jednym z głównych czynników decydujących o podjęciu produkcji danej uprawy jest opłacalność produkcji, na którą wpływ mają między innymi koszty produkcji. Dlatego dla zobrazowania opłacalności produkcji przedstawiono koszty produkcji soi w wybranych gospodarstwach głównych producentów i eksporterów soi na świecie w tym Polsce.
title: Representations of the American War of Independence in the late eighteenth-century English novel
Creators: name: Tarling, Barbara Frances
Publisher: name: The Open University
Year: 2010

description: For metropolitan Britons, the American War of Independence began as a traumatic civil war and ended as a global conflict that threatened the integrity of home and empire. This thesis examines the ways in which writers of popular fiction engaged with that crisis, considers why their preoccupation with the dispute continued for so many years after the peace treaty was signed, and suggests some reasons why the subject ceased to resonate as the century drew to a close. Through a series of individual case studies it explores the diverse ways in which the war is presented in a selection of novels published in Britain during the 1780s and 1790s, and reveals how they are shaped in response to contemporary political imperatives. There has been a tendency to associate the overt politicization of the novel with the intellectual and political ferment of the 1790s but my research shows that this was not the case. Political critique was a key element in fictional representations of the American War. Topical controversies were hotly debated, the morality of the conflict was fiercely contested, and competing constructions of patriotism, nation and empire were interrogated and explored. Few of these works have been studied, however. Charlotte Smith, Robert Bage and Helen Maria Williams are better known for their radical responses to the French Revolution than for their fictional engagement with the events of the American War, whilst writers such as Samuel Jackson Pratt, Eliza Parsons and George Walker are now almost entirely forgotten. Nevertheless, the novels in this study are worthy of attention. Irrespective of their literary merit, which in some cases is considerable, they offer unique insights into the ways in which British writers and readers engaged with the politics of war, empire and revolution both before and after the momentous events of 1789.

description: We present scanning near-field images of surface plasmon modes around a single elliptical nanohole in 88 nm thick Au film. We find that rotating surface plasmon vortex modes carrying extrinsic orbital angular momentum can be induced under linearly polarized illumination. The vortex modes are obtained only when the incident polarization direction differs from one of the ellipse axes. Such a direct observation of the vortex modes is possible thanks to the ability of the SNOM technique to obtain information on both the amplitude and the phase of the near field. The presence of the vortex mode is determined by the rotational symmetry breaking of the system and it can be considered the counterpart of the photonic spin Hall effect. Finite element method calculations show that such a vorticity originates from the presence of nodal points where the phase of the field is undefined, leading to a circulation of the energy flow. The configuration producing vortex modes corresponds to a nonzero total topological charge (+1).
title: Success factors of the franchise-system in the real estate industry : a comparative study of the self-proclaimed "Market Leaders"

description: Franchising is a common business model, which gained popularity in a wide variety of industries in the previous decades. Franchising offers an effective method for building a national network without the essential management establishments, time and capital investment from the company. The other success factor of franchising is the scalability of a structured business model that can usually be applied to every sector, from catering to financial services. Based on this insight, it is quite surprising, that one of the most successful franchise companies is based in the real estate industry, which is by its nature, a business with great regional differences, a complex product and a long decision process of the customer. The company being referred to here is RE/MAX, which provides real estate services in commercial, residential, relocation and asset management, and was founded in 1973 in Denver, United States. Today it has become an international leader in the real estate sector; it built up the biggest and most productive brokerage franchise system in the world. RE/MAX operates with an average of 100,000 sales associates and with more than 6,000 offices in 95 countries. Taking international market-insights into account, it can be concluded that in the long run, the global real estate market will be in the hands of a few huge real estate companies, which will be introduced in this thesis. How can the real estate franchise system be so successful and yet so generally applicable at the same time? The aim of this thesis is to show the main factors that lead a real estate franchise company to success and give an outlook on the development of the real estate brokerage market in Europe, as there are still numerous undeveloped opportunities in this sector.
Completely real? A critical note on the claims by Colbeck and Renner

Subjects: subject: Quantum Physics (quant-ph)

description: In a series of papers Colbeck and Renner claim to have shown that the quantum state provides a complete description for the prediction of future measurement outcomes. In this paper I argue that thus far no solid satisfactory proof has been presented to support this claim. Building on the earlier work of Leifer, Landsman and Leegwater, I present and prove two results that only partially support this claim. I then discuss the arguments by Colbeck, Renner and Leegwater concerning how these results are to generalize to the full claim. This argument turns out to hinge on the implicit use of an assumption concerning the way unitary evolution is to be represented in any possible completion of quantum mechanics. I argue that this assumption is unsatisfactory and that possible attempts to validate it based on measurement theory also do not succeed.

description: On the paths and ideologies to alleviate dependence on carbon derivative fuels in light of climate change, improve energy security in the uncertain world of today coupled with reliability of energy supply, policy makers face some arduous choices and decisions. Prolonging the existing life of certain nuclear power plants helps alleviate some of the concern on a stable, reliable and dependable energy source in the near future while avoiding the hassles of new constructions involving studies, feasibility and assessment tests, etc. Nuclear power generators have a host of issues to consider when undertaking license renewals ranging from technical through regulatory to economics. This paper delves on the decision making process that all inherent parties- plant engineers, managers and operators would face when working together to ensure, when feasible, extension of the existing life of the power generating plant. Understanding the flow of ideas requires a thorough comprehension of the factors that are central to the process. Considering the composition of the atomic power plant in the form of a group cluster simplifies understanding the logical reasoning behind various issues that pertain to the individual constituent components and the group as a whole. Regulatory overview, with frequent checks and proper documentation of the decisions shall help in furthering the learning curve towards a better decision in the future. Logical reasoning aside, an informed decision would involve a plethora of influential factors including operating and maintenance history, technical compatibility, interference patterns, to name a few.
An echo of silence through the vale of oppression : name, literacy, and memory
Creators: name: Chen, Rosa Hong
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines how one’s name and the ways in which that name is employed in various social contexts affects a person’s self-knowing and knowing of the world, focusing specifically on the challenges of literacy acquisition in oppressive nation-states. The work, which employs a narrative methodology, draws upon my experiences of persecution through the Chinese Cultural Revolution, during which time officers of the oppressive regime blacklisted my family name. Being in the stages of early literacy at the time, I came to know my formal identity through glimpses of my name angrily crossed out on blackboards and in other public places. I, along with children like me, was forced to reject my identity in order to fit in the new social order. If, as Norris et al (2005) observe, literacy acquisition "requires some appropriation of the ways-of-being and values of a social group" (p. 779), how do oppressed peoples come to acquire literacy? This work entails an inquiry into the significance of names/naming in relation to three important aspects of knowing: self-image, literacy, and cultural memory. The thesis consists of three primary parts: 1) a general background of the Cultural Revolution in which my family and our experiences of persecution are situated; 2) a discussion of the theoretical implications of name/naming, literacy, identity and cultural memories; 3) and a series of anecdotes that exemplify the inextricable relatedness between name / naming and literacy.
Making top-heavy IMFs from canonical IMFs near the Galactic Centre

description: We show that dynamical evolution in a strong (Galactic Centre-like) tidal field can create clusters that would appear to have very top-heavy IMFs. The tidal disruption of single star forming events can leave several bound `clusters' spread along 20 pc of the orbit within 1-2 Myr. These surviving (sub)clusters tend to contain an over-abundance of massive stars, with low-mass stars tending to be spread along the whole `tidal arm'. Therefore observing a cluster in a strong tidal field with a top-heavy IMF might well not mean the stars formed with a top-heavy IMF.

description: We analyze the evolution of hydrodynamic fluctuations for QCD matter below $T_c$ in the chiral limit, where the pions (the Goldstone modes) must be treated as additional non-abelian superfluid degrees of freedom, reflecting the broken $SU_L(2) \times SU_R(2)$ symmetry of the theory. In the presence of a finite pion mass $m_π$, the hydrodynamic theory is ordinary hydrodynamics at long distances, and superfluid-like at short distances. The presence of the superfluid degrees of freedom then gives specific contributions to the bulk viscosity, the shear viscosity, and diffusion coefficients of the ordinary theory at long distances which we compute. This determines, in some cases, the leading dependence of the transport parameters of QCD on the pion mass. We analyze the predictions of this computation, as the system approaches the $O(4)$ critical point.

description: Experimental and theoretical studies on transport in semiconductor samples with superconducting electrodes are reported. We focus on the samples close to metal-insulator transition. In metallic samples, a peak of negative magnetoresistance at fields lower than critical magnetic field of the leads was observed. This peak is attributed to restoration of a single-particle tunneling emerging with suppression of superconductivity. The experimental results allow us to estimate tunneling transparency of the boundary between superconductor and metal. In contrast, for the insulating samples no such a peak was observed. We explain this behavior as related to properties of transport through the contact between superconductor and hopping conductor. This effect can be used to discriminate between weak localization and strong localization regimes.

Developmental biology of Exacum Styer Group pollen as related to haploid induction
Creators: name: Chiu, Tsan-Yu
Publisher: name: University of British Columbia
Year: 2010

description: Exacum Styer Group, a group of interspecific hybrids, possesses several valuable traits for ornamental use. However, current production techniques are limited to asexual reproduction of selected genotypes. Typically, inbred line development is highly desirable for commercial introduction of F1 hybrids as well as to facilitate genetic research. Unfortunately, this group suffers from severe inbreeding depression, precluding sexually derived inbred lines. In order to avoid inbreeding depression, double haploid plant development is one alternative approach. Therefore, this research developed fundamental information related to the successful application of this technology. Initially, fourteen genotypes were evaluated for pollen viability ranging from 0% to 80.5%. Three genotypes, with different levels of pollen viability, were selected and characterized for microsporogenesis, microgametogenesis, pollen morphology, and chromosome number. Microsporogenesis was normal among all three selected genotypes. However, the low fertility genotype and sterile genotype did not complete normal microgametogenesis and were found to have abnormal exine structure, perhaps indicating a dysfunctional tapetum layer. In contrast, the fertile genotype completed microgametogenesis, produced normal exine, and produced functional pollen grains. At anthesis, pollen was shed at the bi-nucleate stage. The chromosome numbers of the three genotypes evaluated ranged from 50 (fertile genotype) to 66 (low pollen viability). The individual chromosomes ranged in size from 0.3 μm (dot-shaped) to 2.65 μm (rod-shaped) with all three genotypes containing each form. Following characterization of pollen development, reprogramming treatments (e.g., temperature, mannitol, media composition and plant growth regulators) to induce haploid embryogenesis were applied at the mid uninucleate to early binucleate stage. After cold treatment (10°C) for 7 days, microspores maintained normal nuclei development without symmetrical divisions observed, suggesting that no androgenic switch occurred. Furthermore, heat treatment (35°C) for 4 days induced nuclei degradation and microspore non-viability. In addition to temperature treatments, mannitol treatments did not induce symmetrical divisions. When anthers were cultured under common temperature treatments, regardless of media composition, nuclei displayed a similar response indicating temperature was more effective in influencing nuclei development than media composition. Three different auxin and cytokinin combinations were evaluated on androgenic callilembryo induction. However, none of the combinations successfully induced calli/embryo formation.

description: The three-dimensional Hilbert transform takes scalar data on the boundary of a domain in R3 and produces the boundary value of the vector part of a quaternionic monogenic (hyperholomorphic) function of three real variables, for which the scalar part coincides with the original data. This is analogous to the question of the boundary correspondence of harmonic conjugates. Generalizing a representation of the Hilbert transform H in R3 given by T. Qian and Y. Yang (valid in Rn), we define the Hilbert transform Hf associated to the main Vekua equation DW = (Df/f)W in bounded Lipschitz domains in R3. This leads to an investigation of the three-dimensional analogue of the Dirichlet-to-Neumann map for the conductivity equation.

description: A high-precision intra-bunch-train beam orbit feedback correction system has been developed and tested in the ATF2 beamline of the Accelerator Test Facility at the High Energy Accelerator Research Organization in Japan. The system uses the vertical position of the bunch measured at two beam position monitors (BPMs) to calculate a pair of kicks which are applied to the next bunch using two upstream kickers, thereby correcting both the vertical position and trajectory angle. Using trains of two electron bunches separated in time by 187.6~ns, the system was optimised so as to stabilize the beam offset at the feedback BPMs to better than 350~nm, yielding a local trajectory angle correction to within 250~nrad. The quality of the correction was verified using three downstream witness BPMs and the results were found to be in agreement with the predictions of a linear lattice model used to propagate the beam trajectory from the feedback region. This same model predicts a corrected beam jitter of c.~1~nm at the focal point of the accelerator. Measurements with a beam size monitor at this location demonstrate that reducing the trajectory jitter of the beam by a factor of 4 also reduces the increase in the measured beam size as a function of beam charge by a factor of c.~1.6.

description: Copper is an extremely important metal for use in today's industrial society, but it is also known in some circles to be an indicator for economic activity regionally and globally. Additionally, Chinas commodity strength means that copper prices are largely dependent on the economic activity in China. Purchasing professionals have few resources such as those in large trading or commodity houses, therefore an analysis was run using various Chinese economic indicators against the LME copper price using commercially available Chinese economic data from the Trading Economics website. The research was set up in the following manner: 1. Questionnaire sent by email to 5 copper industry professionals asking them to rank from 1 to 10 the most likely highly correlated Chinese Economic Indicators provided with the LME cash settlement copper price. 2. Multiple regression analysis of the variables against LME cash settlement copper prices and tested for auto-correlation. 3. Time Series analysis whereby auto-regressive (AR), auto-regressive with integrated moving average (ARIMA) and generalized autoregressive conditional heteroskedasticity (GARCH) models were tested 4. Proceed with hypothesis testing to be able to determine the significance of the results A multiple regression was run using the various dependent economic variables in order to determine the best indicators as well as a time series analysis to attempt to find the best indicators as well as the best model fit. It was discovered in the regression analysis that the Chinese Leading Economic Indicator Index (P-Value: 0.0889), Chinese Manufacturing Purchasing Managers Index (P-Value: 0.0912), Chinese Exports (P-Value: 0.1440) and the USD/CNY Exchange Rate (P-Value: 0.1560) demonstrate the lowest P values (which is the probability that the data we have seen are purely based on chance) with the lowest autocorrelation and thus the best dependent variables against the LME copper prices.

description: We give a Pfaffian formula to compute the partition function of the Ising model on any graph $G$ embedded in a closed, possibly non-orientable surface. This formula, which is suitable for computational purposes, is based on the relation between the Ising model on $G$ and the dimer model on its terminal graph $G^T$. By combining the ideas of Loebl-Masbaum \cite{Loeb11}, Tesler \cite{Tes2000}, Cimasoni \cite{Cim09, Cim10} and Chelkak-Cimasoni-Kassel \cite{Chel15}, we give an elementary proof for the formula.

description: We study the composition of the Galactic interstellar medium (ISM) toward the Galactic center region (5 < |l| < 20 degree) by utilizing X-ray absorption features of three bright low-mass X-ray binaries (LMXBs), GX 13+1, GX 5-1, and GX 340+0, observed with the Chandra HETGS. We detect X-ray absorption fine structure (XAFS) of the Si K-edge, characterized by a narrow and a broad absorption feature at 1846 and ~1865 eV, respectively. Comparison with ground experimental data indicates that most of the ISM Si exists in the form of silicates, although a composition of "pure" forsterite is ruled out. The XAFS spectra of the sulfur K-edge indicate that a significant fraction of S exists in the gas phase. From each source, we derive the column densities of Mg, S, Si, and Fe from the K-edge depth and that of O (or H) from the absorption of the continuum. The elemental abundance ratios are found to be consistent between the three targets: the mean values of O/Si, Mg/Si, S/Si, and Fe/Si are determined to be 0.55+-0.17, 1.14+-0.13, 1.03+-0.12, and 0.97+-0.31 solar, respectively (90% error in the mean value). We discuss the origins of the overabundances of the heavy metals relative to O in the Galactic ISM by comparison with the abundance pattern of the intracluster medium in clusters of galaxies. Assuming that most of the Mg and Si atoms are depleted into silicates of either the proxine or olivine family, we estimate that the number ratio of Mg to Fe in olivine is >~1.2 and that 17%-43% of the total O atoms in the ISM must be contained in silicate grains.

description: The main goal of this study is to find the answer to the question of how can be mitigated the resistance to changes in such a complex IT projects. In this work the author is assuming that the resistance to changes can be mitigated via the improvement of communications and via involvement of end-users into MIS development process. The main hypothesis of this study is that the communications with end users could be improved via a web-based annual interview. The Introduction section offered a brief overview of objectives, goals and the author's motivation of this study. It also contains the short introduction of the State Savings Bank of Ukraine as the bank under investigation within this study. In the first chapter, the author analyses the bank value chain and business model and its connection to IT architecture and MIS organisation. The Chapter introduces the importance of the existence at the bank of the clear business architecture and main organizational functions before the start of any fundamental changes. Chapter two offers a case study of the MIS and DWH implementation at the State Savings Bank of Ukraine based on IBM BDW and IBM Cognos BI tools. It provides a short introduction and background of the project, and presents the project management methodology applied. This chapter summarizes the key success factors of the project. In this chapter, the author uses IBM manual books and presentation materials for the IBM BDW implementation projects. Chapter Three presents the questionnaire that has been developed to involve the State Savings Bank of Ukraine' top and middle management into creating a shared vision of strategic KPIs of the bank for MIS. The chapter introduces the methodological approach applied for the questionnaire development, and formulates the interview objectives. The author describes target groups of the interview, and explains the questionnaire structure. The last section of questionnaire also includes the demand assessment for other BI reporting in 2016. It strives to involve bank management into reports systematization and prioritization. At the end of this paper, the author concludes that an annual questionnaire can be used as a tool to build up communication and to involve users in MIS development process at all levels of organisation on an on-going basis.

description: Current online learning methods suffer issues such as lower convergence rates and limited capability to select important features compared to their offline counterparts. In this paper, a novel framework for online learning based on running averages is proposed. Many popular offline regularized methods such as Lasso, Elastic Net, Minimax Concave Penalty (MCP), and Feature Selection with Annealing (FSA) have their online versions introduced in this framework. The equivalence between the proposed online methods and their offline counterparts is proved, and then novel theoretical true support recovery and convergence guarantees are provided for some of the methods in this framework. Numerical experiments indicate that the proposed methods enjoy high true support recovery accuracy and a faster convergence rate compared with conventional online and offline algorithms. Finally, applications to large datasets are presented, where again the proposed framework shows competitive results compared to popular online and offline algorithms.
