description: Let G be a reductive complex Lie group with Lie algebra g. We call a subgroup H of G {\bf cramped} if there is an integer b(G,H) such that each finite dimensional representation of G has a non-trivial invariant subspace of dimension less than b(G,H). We show that a subgroup is cramped if and only if the moment map from T^*(K/L) to k^* is surjective, where K and L are compact forms of G and H. We will use this in conjunction with sufficient conditions for crampedness given by Willenbring and Zuckerman (2004) to prove a geometric lemma on the intersections between adjoint orbits and Killing orthogonals to subgroups. We will also discuss applications of the techniques of symplectic geometry to the generalized Harish-Chandra modules introduced by Penkov and Zuckerman (2004), of which our results on crampedness are special cases.

description: The current thesis, is a first attempt in the development and utilization of e-Government services in the Greek Local Authorities, as they were formed by the implementation of ‘Kapodistrias’ program and being currently restructured by the ‘Kallikratis’ program. In the frameword of this thesis, the following actions were implemented: 1. Exploration of the conditions, context and constraints for the development and provision of e-government applications in local authorities. 2. Forming of an application development framework, which will be compatible with the requests of the previous paragraph. 3. Development of e-go modules, concerning the delivery of the decisions of the Municipal Council and the Municipal Committee to the citizens, as well as the interactive system of placement and subsequent resolving actions of citizens’ Requests and Complaints. The aforementioned development, made use of the existing infrastructure in terms of equipment and personnel in order to successfully implement and utilize these applications. In that context also, the usage of free-of-charge and/or open source technologies is –almost- obligatory.

Hypermedia: modes of communication in world order transformation
Creators: name: Deibert, Ronald James
Publisher: name: University of British Columbia
Year: 2009

description: Despite that we are in the midst of profound changes in communications technologies, there is a remarkable gap in the International Relations literature devoted to exploring the implications of these changes. In part, this can be attributed to the discipline’s conservative tendencies; generally, International Relations theorists have resisted studying major discontinuity in the international system. The few studies that do attempt to account for change typically focus on modes of production or destruction as determinant variables. Though there are rare exceptions, many of them also tend towards a form of mono-causal reductionism. When considered at all, communications technologies are viewed through the prism of, or are reduced to, these other factors. This study seeks to remedy this gap by examining the relationship between large-scale shifts in modes of communication and “world order” transformation -- the structure or architecture of political authority at a world-level. Drawing from the work of various “medium theory” scholars, such as Harold Innis and Marshall McLuhan, the study outlines an open-ended, non-reductive theory at the core of which is the argument that changes in modes of communication facilitate and constrain social forces and ideas latent in society. This hypothesized process can be likened to the interaction between species and a changing natural environment: new communications environments “favour” certain social forces and ideas by means of a functional bias towards some and not others, much the same as environments determine which species prosper by “selecting” for certain physical characteristics. In other words, social forces and ideas survive differentially according to their “fitness” or match with the new communications environment -- a process that is both open ended and contingent. The study is organized into two parts: Part one examines the relationship between printing and the medieval to modem world order transformation in Europe; Part two examines the relationship between new digital-electronic-telecommunications (called “hypermedia”) and the modem to postmodern world order transformation. The study suggests that the hypermedia communications environment is contributing to the dissolution of modern world order by facilitating the transnationalization of production, the globalization of finance, the rise of complex, non-territorial social networks, and the de-massification of “national” identities. The hypermedia environment is also helping to re-focus security concerns from an inter-national to an intra-planetary context. While it is far too early to provide a clear outline of the emerging postmodern world order, the trends that are unearthed in this study point away from single mass identities, linear political boundaries, and exclusive jurisdictions centred on territorial spaces, and towards multiple identities and non-territorial communities, overlapping boundaries, and non-exclusive jurisdictions.

description: General image super-resolution techniques have difficulties in recovering detailed face structures when applying to low resolution face images. Recent deep learning based methods tailored for face images have achieved improved performance by jointly trained with additional task such as face parsing and landmark prediction. However, multi-task learning requires extra manually labeled data. Besides, most of the existing works can only generate relatively low resolution face images (e.g., $128\times128$), and their applications are therefore limited. In this paper, we introduce a novel SPatial Attention Residual Network (SPARNet) built on our newly proposed Face Attention Units (FAUs) for face super-resolution. Specifically, we introduce a spatial attention mechanism to the vanilla residual blocks. This enables the convolutional layers to adaptively bootstrap features related to the key face structures and pay less attention to those less feature-rich regions. This makes the training more effective and efficient as the key face structures only account for a very small portion of the face image. Visualization of the attention maps shows that our spatial attention network can capture the key face structures well even for very low resolution faces (e.g., $16\times16$). Quantitative comparisons on various kinds of metrics (including PSNR, SSIM, identity similarity, and landmark detection) demonstrate the superiority of our method over current state-of-the-arts. We further extend SPARNet with multi-scale discriminators, named as SPARNetHD, to produce high resolution results (i.e., $512\times512$). We show that SPARNetHD trained with synthetic data cannot only produce high quality and high resolution outputs for synthetically degraded face images, but also show good generalization ability to real world low quality face images.

description: The way students transport to and from school, along with the problems created by overuse of private transportation, has been investigated over the last years in global level. Several attends have been made to improve pedestrians’ street environment and encourage the movement of special groups (such as elementary students) by walking or cycling. Their target is to reduce traffic flow in school areas and further improve the environment and fitness. The subject of the research is to evaluate pedestrian service facilities provided in elementary schools’ areas. The following research has been conducted in the surrounding area of three different elementary schools in the city of Thessaloniki. Each area presents with different characteristics, regarding the development of land use in the area, connected to the traffic flow and the provided pedestrian facilities in the street network. Credible tools from global bibliography have been used to evaluate the street environment.

description: We characterize the kinematic and chemical properties of 589 Galactic Anticenter Substructure Stars (GASS) with K-/M- giants in Integrals-of-Motion space. These stars likely include members of previously identified substructures such as Monoceros, A13, and the Triangulum-Andromeda cloud (TriAnd). We show that these stars are on nearly circular orbits on both sides of the Galactic plane. We can see velocity($V_{Z}$) gradient along Y-axis especially for the south GASS members. Our GASS members have similar energy and angular momentum distributions to thin disk stars. Their location in [$α$/M] vs. [M/H] space is more metal poor than typical thin disk stars, with [$α$/M] \textbf{lower} than the thick disk. We infer that our GASS members are part of the outer metal-poor disk stars, and the outer-disk extends to 30 kpc. Considering the distance range and $α$-abundance features, GASS could be formed after the thick disk was formed due to the molecular cloud density decreased in the outer disk where the SFR might be less efficient than the inner disk.

description: The structure of the high galactic latitude Cometary Globule 12 (CG 12) has been investigated by means of radio molecular line observations. Detailed, high signal to noise ratio maps in C18O (1-0), C18O (2-1) and molecules tracing high density gas, CS (3-2), DCO+ (2-1) and H13CO+ (1-0), are presented. The C18O line emission is distributed in a 10' long North-South elongated lane with two strong maxima, CG12 N(orth) and CG12 S(outh). In CG12 S the high density tracers delineate a compact core, DCO+ core, which is offset by 15" from the C18O maximum. The observed strong C18O emission traces the surface of the DCO+ core or a separate, adjacent cloud component. The emission in high density tracers is weak in CG12 N and especially the H13CO+, DCO+ and N2H+ lines are +0.5 km/s offset in velocity with respect to the C18O lines. Evidence is presented that the molecular gas is highly depleted. The observed strong C18O emission towards CG12 N originates in the envelope of this depleted cloud component or in a separate entity seen in the same line of sight. The C18O lines in CG 12 were analyzed using Positive Matrix Factorization, PMF. The shape and the spatial distribution of the individual PMF factors fitted separately to the C18O (1-0) and (2-1) transitions were consistent with each other. The results indicate a complex velocity and line excitation structure in the cloud. Besides separate cloud velocity components the C18O line shapes and intensities are influenced by excitation temperature variations caused by e.g, the molecular outflow or by molecular depletion. Assuming a distance of 630 pc the size of the CG 12 compact head, 1.1 pc by 1.8 pc, and the C18O mass larger than 100 Msun are comparable to those of other nearby low/intermediate mass star formation regions.

description: A distributed optimal control problem for an extended model of phase field type for tumor growth is addressed. In this model, the chemotaxis effects are also taken into account. The control is realized by two control variables that design the dispensation of some drugs to the patient. The cost functional is of tracking type, whereas the potential setting has been kept quite general in order to allow regular and singular potentials to be considered. In this direction, some relaxation terms have been introduced in the system. We show the well-posedness of the state system, the Fréchet differentiability of the control-to-state operator in a suitable functional analytic framework, and, lastly, we characterize the first-order necessary conditions of optimality in terms of a variational inequality involving the adjoint variables.

description: We investigate the absorption and emission features in observations of GX 301-2 detected with Insight-HXMT/LE in 2017-2019. At different orbital phases, we found prominent Fe Kalpha, Kbeta and Ni Kalpha lines, as well as Compton shoulders and Fe K-shell absorption edges. These features are due to the X-ray reprocessing caused by the interaction between the radiation from the source and surrounding accretion material. According to the ratio of iron lines Kalpha and Kbeta, we infer the accretion material is in a low ionisation state. We find an orbital-dependent local absorption column density, which has a large value and strong variability around the periastron. We explain its variability as a result of inhomogeneities of the accretion environment and/or instabilities of accretion processes. In addition, the variable local column density is correlated with the equivalent width of the iron Kalpha lines throughout the orbit, which suggests that the accretion material near the neutron star is spherically distributed.

Studies on the direct vascular actions of diuretics

Publisher: name: University of British Columbia
Year: 2009

description: Although thiazide diuretics have been a mainstay of the drug therapy for the treatment of hypertension for over 30 years, the exact mechanism by which they reduce blood pressure is not known. In this thesis, the direct vascular actions of a thiazide diuretic (hydrochlorothiazide) were compared with those of thiazide like diuretics (chlorthalidone and indapamide) and a loop diuretic (furosemide). The vascular actions of these four diuretics were studied in the presence and absence of plasma solutions on the following tissue preparations: rat aortic rings, rat pulmonary artery rings, human uterine artery rings, and the rat perfused mesenteric bed. Whole animal experiments were conducted in control and a hypertensive rat model (DOCA/salt treated). Acute hypotensive effects of the diuretics were measured in rats with ligated ureters to prevent any diuretic effect. Acute tissue blood flow effects were also measured using the reference sample method with radioactively-label led microspheres. Results: (1) Diuretics possess a direct vasorelaxant effect only in the presence of plasma on in vitro arterial preparations. (2) This in vitro relaxant effects is endothelium-independent. (3) Albumin was found to be the main plasma cofactor required by diuretics. (4) Preincubation with albumin enables tissues to retain their responsiveness to diuretics in Krebs solution alone. (5) Excess albumin appears to decrease the vasorelaxant action of diuretics, presumably due to binding of the diuretics to albumin. (6) Diuretics possess acute blood pressure lowering and vasodilating effects in hypertensive animals by a mechanism independent of diuresis. (7) These in vivo effects are due to decreased total peripheral resistance and increased blood flow to specific vascular beds (intestine and kidney). (8) The potency of the vasorelaxant actions of the four diuretics tested in the various preparations is reproducible (indapamide > hydrochiorothiazide > chiorthalidone > furosemide) and is consistent. with their clinical antihypertensive potency. (9) Hydrochlorothiazide and chiorthalidone in plasma directly relax vascular smooth muscle by acting on calcium-activated potassium channels whereas indapamide and furosemide act by a different mechanism which is not prostaglandin-dependent. These data suggest that diuretics possess a direct vasorelaxant action which may be important to the antihypertensive action of these drugs.
How Can We Utilize Natural Language Processing to Identify Bias in Job Descriptions?

description: In the pursuit of creating fairer hiring practices and promoting workforce diversity, this research project explores the potential of Natural Language Processing (NLP) techniques to identify and rectify biases in job descriptions. The language used in job postings can inadvertently perpetuate biases and deter applicants from underrepresented backgrounds. Leveraging cutting-edge NLP methods, this study aims to automatically detect and address biases, fostering a more inclusive recruitment process. By examining the biases within job descriptions, organizations can attract a more diverse range of applicants and cultivate an inclusive workplace culture. Through the application of NLP, this research seeks to drive positive change in recruitment practices, ultimately contributing to a more equitable job market.

description: On basis of modification of Einstein's gravitational equations by adding the term $f(R)\propto βR^n$, a geometric model of quintessence is proposed. The evolution equation for the scale factor $a$ of the Universe is analyzed for the two parameters $n=2$ and $n=4/3$, which were preferred by previous studies of the early Universe. Another choice of parameters $n$ and $β$ is proposed from the following reasons: the exponent $n$ close to 1.2953 follows from the request for the evolution of the Universe after recombination to be close to the evolution of the flat FRW model with cold dark matter and reasonable age of the Universe defines the value of the coefficient $β$. Such a model corresponding to the evolution of the Universe with the dynamical $Λ$-term describes well enough the observational data.

Pediyatrik hastada Migren

description: Baş ağrısı; pediatrik hastalarda acil servise başvuruların %1’ini oluşturmaktadır. Bu hastaların %40’ı primer başağrısı tanısı almaktadır ve bunların %75’i ise migrendir (1). Migren sık gözüken, kronik seyirli, ciddi başağrısı atakları ile karakterize bir nörovasküler hastalıktır(2). Bazı hastalarda nörolojik semptomlar (aura) mevcuttur. Migren altta genetik faktörlerin rol oynadığı bir primer baş ağrısı sebebidir (2). Eskiden migrenin sadece vasküler sebeplerden kaynaklanan bir durum olduğu düşünülürdü. Ancak vasküler mekanizmalar; migren ataklarını tamamen aydınlatmada yetersiz kalmaktadır. Beyin sapının ve inen ve çıkan yollarının da dahil olduğu kompleks nörolojik mekanizmaların rol oynadığı düşünülmektedir. Bu yüzden artık migren; nörovasküler bir hastalık olarak kabul edilmektedir (2). Migren; sık gözüken (%80)aurasız tip ve daha nadir gözüken (%20) spesifik, reversibl nörolojik semptomlarla ve auralarla karakterize klasik tip olmak üzere 2’ye ayrılmaktadır. Auralar genelde 10-20 dk içerisinde gerilemektedir. En sık görüleni görsel auralardır (2). Pediatrik migren atakları genel olarak; bilatearal veya unilateral (frontal/temporal), pulsatil, rutin/günlük aktivitelerle başlayabilen, ağrıların 1-48 saat sürebildiği özelliktedir. Bulantı, kusma, iştahsızlık,fotofobi, fonofobi, osmofobi ve bulanık görme gibi semptomlar eşlik edebilir. Hatta bazı hastalarda unutkanlık, depresyon, mani atakları görülebilir (2,3)

Έχει λοιπόν χρησιμοποιηθεί στην πρόγνωση, ιατρική διάγνωση και χρησιμοποιείται πολύ και στην εκτίμηση κόστους έργων λογισμικού. Η παραδοσιακή CBR ωστόσο έχει έναν περιορισμό: δεν έχει κάποιο κριτήριο επιλογής των πλησιέστερων γειτόνων (περιπτώσεων δηλαδή). Αυτό συνεπάγεται την επιλογή του ίδιου, ξανά και ξανά, αριθμού, ανεξάρτητα του έργου, την εκτίμηση του οποίου αναζητούμε. Ο σταθερός αυτός αριθμός γειτόνων λοιπόν δημιουργεί ένα πρόβλημα, όταν κάποια προς εκτίμηση έργα θα χρειάζονταν παραπάνω/λιγότερο αριθμό γειτόνων για μια καλύτερη εκτίμηση. Αυτό σημαίνει πως η παραδοσιακή EbA δεν εγγυάται βέλτιστο αριθμό γειτόνων για βέλτιστη εκτίμηση για διαφορετικά προς εκτίμηση έργα. Στην εργασία αυτή προσπαθήσαμε να παρακάμψουμε το πρόβλημα αυτό αναπτύσσοντας δυο αλγορίθμους, σκοπός των οποίων ήταν η εύρεση του βέλτιστού αριθμού γειτόνων για το κάθε προς εκτίμηση έργο.
description: Case-based reasoning (CBR) has been used in various problem-solving areas such as financial forecasting, software cost estimation, credit analysis and medical diagnosis. However, conventional CBR has the limitation that it has no criterion for choosing the nearest cases based on the probabilistic similarity of cases. It uses a fixed number of neighbors without considering an optimal number for each target case, so it does not guarantee optimal similar neighbors for various target cases. This leads to the weakness of lowering predictability due to deviation from desired similar neighbors. In this thesis we suggest a new case extraction technique based on the distribution of distances. The main idea involves a dynamic adaptation of the optimal number of neighbors by considering the distribution of distances between potential similar neighbors for each target case. In order to do this, our technique finds a distance threshold and selects similar neighbors satisfying the distance threshold criterion. We apply this new method to four real-life software engineering data sets and compare the results with those of the conventional EbA.

description: \textit{Parker Solar Probe} has shown the ubiquitous presence of strong magnetic field deflections, namely switchbacks, during its first perihelion where it was embedded in a highly Alfvénic slow stream. Here, we study the turbulent magnetic fluctuations around ion scales in three intervals characterized by a different switchback activity, identified by the behaviour of the magnetic field radial component, $B_r$. \textit{Quiet} ($B_r$ does not show significant fluctuations), \textit{weak} ($B_r$ has strong fluctuations but no reversals) and \textit{strong} ($B_r$ has full reversals) periods show a different behaviour also for ion quantities and Alfvénicity. However, the spectral analysis shows that each stream is characterized by the typical Kolmogorov/Kraichnan power law in the inertial range, followed by a break around the characteristic ion scales. This frequency range is characterized by strong intermittent activity, with the presence of non-compressive coherent structures, such as current sheets and vortex-like structures, and wave packets, identified as ion cyclotron modes. Although, all these intermittent events have been detected in the three periods, they have a different influence in each of them. Current sheets are dominant in the \textit{strong} period, wave packets are the most common in the \textit{quiet} interval; while, in the \textit{weak} period, a mixture of vortices and wave packets is observed. This work provides an insight into the heating problem in collisionless plasmas, fitting in the context of the new solar missions, and, especially for \textit{Solar Orbiter}, which will allow an accurate magnetic connectivity analysis, to link the presence of different intermittent events to the source region.

description: Over the last years, there has been a coordinated effort in Europe through the Inspire directive (2007/2/EC/3-14-2007) for the creation of a unified, up-to-date and detailed spatial comprised of data which will be provided and properly combined by all Member States. The cadastral parcel constitutes the core unit of the Inspire Directive which was updated in September 2009, and more specifically a framework was developed concerning the cadastral parcel and the quality and properties of the final products. Also in this update the Land Administration model was announced as the Principal Cadastral Model. The dissertation Aims at investigating the compatibility of the cadastral models, presented and proposed by Ktimatologio S.A. and the Inspire Directive and more specifically at examining how the issue of parcel boundaries is treated. The dissertation ends with proposals regarding how compatibility can be achieved on the above mentioned examined field.

description: We numerically investigate how an asteroid's elongation controls the sensitivity of its surface to tidal effects during a distant planetary encounter beyond the Roche limit. We analyze the surface slope and its variation by considering the shape elongation, as well as the spin period and orbital conditions. A more elongated asteroid tends to have a higher slope variation, while there may not be a monotonic increase of the total area having such a variation

description: We describe a first-principles method for calculating electronic structure, vibrational modes and frequencies, electron-phonon couplings, and inelastic electron transport properties of an atomic-scale device bridging two metallic contacts under nonequilibrium conditions. The method extends the density-functional codes SIESTA and TranSIESTA that use atomic basis sets. The inelastic conductance characteristics are calculated using the nonequilibrium Green's function formalism, and the electron-phonon interaction is addressed with perturbation theory up to the level of the self-consistent Born approximation. While these calculations often are computationally demanding, we show how they can be approximated by a simple and efficient lowest order expansion. Our method also addresses effects of energy dissipation and local heating of the junction via detailed calculations of the power flow. We demonstrate the developed procedures by considering inelastic transport through atomic gold wires of various lengths, thereby extending the results presented in [Frederiksen et al., Phys. Rev. Lett. 93, 256601 (2004)]. To illustrate that the method applies more generally to molecular devices, we also calculate the inelastic current through different hydrocarbon molecules between gold electrodes. Both for the wires and the molecules our theory is in quantitative agreement with experiments, and characterizes the system-specific mode selectivity and local heating.

Isospin Properties of ($K^-$, $N$) Reactions for the Formation of Deeply-bound Antikaonic Nuclei

description: The formation of deeply-bound antikaonic $K^-/\bar{K}^0$ nuclear states by nuclear ($K^-$, $N$) reactions is investigated theoretically within a distorted-wave impulse approximation (DWIA), considering the isospin properties of the Fermi-averaged $K^-+ N \to N + \bar{K}$ elementary amplitudes. We calculate the formation cross sections of the deeply-bound $\bar{K}$ states by the ($K^-$, $N$) reactions on the nuclear targets, $^{12}$C and $^{28}$Si, at incident $K^-$ lab momentum $p_{K^-}$ = 1.0 GeV/c and $θ_{\rm lab} = 0^{\circ}$, introducing a complex effective nucleon number $N_{\rm eff}$ for unstable bound states in the DWIA. The results show that the deeply-bound $\bar{K}$ states can be populated dominantly by the ($K^-$, $n$) reaction via the total isoscalar $ΔT=0$ transition owing to the isospin nature of the $K^-+ N \to N + \bar{K}$ amplitudes, and that the cross sections described by ${\rm Re}N_{\rm eff}$ and ${\rm Arg}N_{\rm eff}$ enable to deduce the structure of the $\bar{K}$ nuclear states; the calculated inclusive nucleon spectra for a deep $\bar{K}$-nucleus potential do not show distinct peak structure in the bound region. The few-body $\bar{K}\otimes [NN]$ and $\bar{K}\otimes [NNN]$ states formed in ($K^-$, $N$) reactions on $s$-shell nuclear targets, $^3$He, $^3$H and $^4$He, are also discussed.

The Interplay between Star Formation and the Nuclear Environment of our Galaxy: Deep X-ray Observations of the Galactic Center Arches and Quintuplet Clusters

description: The Galactic center (GC) provides a unique laboratory for a detailed examination of the interplay between massive star formation and the nuclear environment of our Galaxy. Here, we present an 100 ks Chandra ACIS observation of the Arches and Quintuplet star clusters. We also report on a complementary mapping of the dense molecular gas near the Arches cluster made with the Owens Valley Millimeter Array. The number-flux relation of point-like X-ray sources indicates an over-population of relatively bright X-ray sources, which are apparently associated with the clusters. The sources in the core of the Arches and Quintuplet clusters are most likely extreme colliding wind massive star binaries. The diffuse X-ray emission from the core of the Arches cluster has a spectrum showing a 6.7-keV emission line and a surface intensity profile declining steeply with radius, indicating an origin in a cluster wind. In the outer regions near the Arches cluster, the overall diffuse X-ray enhancement demonstrates a bow shock morphology and is prominent in the Fe Kalpha 6.4-keV line emission. Much of this enhancement may result from an ongoing collision between the cluster and the adjacent molecular cloud. The older and less compact Quintuplet cluster contains much weaker X-ray sources and diffuse emission, probably originating from low-mass stellar objects as well as a cluster wind. However, the overall population of these objects, constrained by the observed total diffuse X-ray luminosities, is substantially smaller than expected for both clusters. This deficiency of low-mass objects may be a manifestation of the unique star formation environment of the Galactic center.

Σκοπός της παρούσας μεταπτυχιακής μου διατριβής είναι η ανάπτυξη ενός μοντέλου για την οργάνωση παραγωγής των γεωργικών εκμεταλλεύσεων, στο οποίο εμπλέκονται περισσότεροι του ενός αποφασίζοντες και χρησιμοποιούνται περισσότερα του ενός αντικρουόμενα κριτήρια. Για το σκοπό αυτό εφαρμόζεται η μεθοδολογία του διεπίπεδου γραμμικού προγραμματισμού στην οργάνωση των γεωργικών εκμεταλλεύσεων και ειδικότερα στην εύρεση του άριστου σχεδίου παραγωγής.

description: Farm planning usually uses linear or nonlinear mathematical programming models, which generally achieve one goal or more goals of one decision maker. In this master thesis a Bilevel Linear Programming Model was developed for farm planning, which includes more than one decision makers and uses two different conflicting criteria as goals. To this end, the methodology of Bilevel Linear Programming was applied for farm planning in order to achieve the optimal production plan. The two different levels of BLP use the conflicting criteria of gross margin maximization for the farmer (first level) and the fertilizers use minimization representing the community (second level), through the protection of sensitive to the nitrates areas of the Rural Development Plan 2007-2013. Finally, the results obtained from BLP are compared with those of the linear programming model.
