Compromise solutions for bankruptcy situations: a note

Although classic bankruptcy problems take into account a single claims vector, Pulido et al. (2008) show that there are real bankruptcy situations where agents face more than one reference vector. In particular, they consider the claims and an additional reference vector. To analyze these situations, they propose the extreme and the diagonal approaches. Nonetheless, the former approach depends on the order of the vectors: if we interchange the claims and the reference vectors, the result changes. Moreover their study is limited to the case in which the reference vector is lower than the claims vector. In the present note, we propose an extension that solves these short- comings by introducing the idea of impartiality. Keywords: bankruptcy problems; reference point; compromise solution; impartiality.

On the choice of posittioning and cluster size for fixed relay stations in a LTE network

The long term evolution (LTE) is one of the latest standards in the mobile communications market. To achieve its performance, LTE networks use several techniques, such as multi-carrier technique, multiple-input-multiple-output and cooperative communications. Inside cooperative communications, this paper focuses on the fixed relaying technique, presenting a way for determining the best position to deploy the relay station (RS), from a set of empirical good solutions, and also to quantify the associated performance gain using different cluster size configurations. The best RS position was obtained through realistic simulations, which set it as the middle of the cell's circumference arc. Additionally, it also confirmed that network's performance is improved when the number of RSs is increased. It was possible to conclude that, for each deployed RS, the percentage of area served by an RS increases about 10 %. Furthermore, the mean data rate in the cell has been increased by approximately 60 % through the use of RSs. Finally, a given scenario with a larger number of RSs, can experience the same performance as an equivalent scenario without RSs, but with higher reuse distance. This conduces to a compromise solution between RS installation and cluster size, in order to maximize capacity, as well as performance.

A multi-objective optimization of the active and reactive resource scheduling at a distribution level in a smart grid context

In the traditional paradigm, the large power plants supply the reactive power required at a transmission level and the capacitors and transformer tap changer were also used at a distribution level. However, in a near future will be necessary to schedule both active and reactive power at a distribution level, due to the high number of resources connected in distribution levels. This paper proposes a new multi-objective methodology to deal with the optimal resource scheduling considering the distributed generation, electric vehicles and capacitor banks for the joint active and reactive power scheduling. The proposed methodology considers the minimization of the cost (economic perspective) of all distributed resources, and the minimization of the voltage magnitude difference (technical perspective) in all buses. The Pareto front is determined and a fuzzy-based mechanism is applied to present the best compromise solution. The proposed methodology has been tested in the 33-bus distribution network. The case study shows the results of three different scenarios for the economic, technical, and multi-objective perspectives, and the results demonstrated the importance of incorporating the reactive scheduling in the distribution network using the multi-objective perspective to obtain the best compromise solution for the economic and technical perspectives.

Tietoliikenteen tulevaisuuden näkymiä - Etelä-Karjala 2018

Tekniikan kehitys menee vauhdilla eteenpäin ja uusi verkkotekniikoita syntyy koko ajan. Haasteita tuottavat sopivien verkkotekniikoiden löytäminen käyttöön tietylle alueelle ja joissakin tapauksissa joudutaan tyytymään kompromissiratkaisuihin. Lyhyen kantaman langattomat kommunikaatioteknologiat soveltuvat esimerkiksi haja-asutusalueille ja saaristoon, mikäli perinteisen kuidun vetäminen niille alueille ei ole mahdollista. Tässä työssä tuodaan esille niitä langallisia ja langattomia tekniikoita, jotka ovat tällä hetkellä tai tulevaisuudessa merkityksellisiä Etelä-Karjalan kannalta. Osa tekniikoista voi jäädä kokonaan pois käytöstä kymmenen vuoden sisällä tai ne voivat yhdistyä ja muuttaa muotoaan. Työn tuloksena syntyneen kartoituksen perusteella saadaan visio siitä, miltä Etelä-Karjalan tilanne näyttää vuonna 2018. Nyt on jo tiedossa Soneran puhelinlankaverkon alasajo lähivuosina ja kuidun vetäminen viemäriin viemäröintitöiden yhteydessä. Tulevaisuuden kaistankäyttötarpeet ja erilaisten palvelujen lisääntyminen edesauttavat viihdepalveluiden tarjonnan monipuolistumista. Open Access ja triple-play ovat tulevaisuuden termejä. Viihteen lisäksi myös muilla eri osa-alueilla kuten työelämässä, sairaaloissa ja kouluissa on tarvetta laajakaistaisille monipalveluille.

Adsorção e dessorção aniônicas individuais por gibbsita pedogenética

Anion adsorption/desorption dynamics was studied as individual processes on surface of particles of a gibbsitic clay. The data suggest a remarkable gibbsite role as nitrate leaching retardant in soil. The opposite behavior of gibbsite towards adsorption/desorption of silicate and phosphate suggests the need of an adequate compromise solution regarding interval and rate applications of anions in cultivated gibbsitic soils. The high P adsorption verified in pH values lower than that reported for the point of zero charge of synthetic Al-hydroxides implies that this process takes place in pedogenic gibbsites through inner sphere complexation.

Kestomagnetoidun roottorin mekaniikkasuunnittelu ja -analysointi

Työssä kehitettiin suurnopeuskäyttöön soveltuva kestomagnetoitu roottori olemassa olevan induktiokoneen staattorirunkoon. Kehitystyön tarkoituksena oli selvittää roottorin mekaaniset raja-arvot, kuten maksimi kehänopeus. Samalla otettiin kantaa myös tarvittaviin analysointi- ja mitoitusmenetelmiin. Maksimi kehänopeuden, laakeroinnin ja roottorin skaalattavuuden selvittäminen edellytti myös tarkkaa materiaaliselvitystä ja optimointia. Tästä syystä työn aikana tehtiin tiivistä yhteistyötä materiaalitoimittajien kanssa. Työn tuloksena syntyi uusi menetelmä toteuttaa radiaalisen magneettivuon luova kestomagneettiroottori 200 m/s kehänopeudelle. Suunniteltua roottoriratkaisua käytetään testausroottorina, jolla selvitetään valmistuksen, kokoonpanon ja sähkötehon rajoitteet käytännössä. Suunnittelutyö edellyttikin jatkuvaa iterointia sähkösuunnittelun ja roottorin osien valmistajien kanssa, jotta löydettiin paras kompromissiratkaisu roottorin prototyyppiin. Tämän seurauksena saatiin luotua varsin tarkat suunnittelu- ja analysointiraja-arvot kestomagneettiroottorin tuotteistettavia versioita varten.

Sobre o sistema de amortização linear crescente

Aiming to reach a compromise solution to the issues of default risk and the payment capacity of takers of housing loans, Jorge Oscar de Mello Flôres submited to the Banco Nacional de Habitação, which was then in charge of the Brazilian System of Housing Financing, what he named as the Linearly Increasing System of Amortization. (LISA). Following a critical analysis of the LISA, it is proposed the alternative named as the Generalyzed System of Mixed Amortization (GSMA).

Optimizing the creation of base populations for aquaculture breeding programs using phenotypic and genomic data and its consequences on genetic progress

The success of an aquaculture breeding program critically depends on the way in which the base population of breeders is constructed since all the genetic variability for the traits included originally in the breeding goal as well as those to be included in the future is contained in the initial founders. Traditionally, base populations were created from a number of wild strains by sampling equal numbers from each strain. However, for some aquaculture species improved strains are already available and, therefore, mean phenotypic values for economically important traits can be used as a criterion to optimize the sampling when creating base populations. Also, the increasing availability of genome-wide genotype information in aquaculture species could help to refine the estimation of relationships within and between candidate strains and, thus, to optimize the percentage of individuals to be sampled from each strain. This study explores the advantages of using phenotypic and genome-wide information when constructing base populations for aquaculture breeding programs in terms of initial and subsequent trait performance and genetic diversity level. Results show that a compromise solution between diversity and performance can be found when creating base populations. Up to 6% higher levels of phenotypic performance can be achieved at the same level of global diversity in the base population by optimizing the selection of breeders instead of sampling equal numbers from each strain. The higher performance observed in the base population persisted during 10 generations of phenotypic selection applied in the subsequent breeding program.

The Judicial Dimension of the European Neighbourhood Policy. EU Diplomacy Paper 08/2013, November 2013

In this paper, the expression “neighbourhood policy” of the European Union (EU) is understood in a broad way which includes the members of the European Free Trade Association (EFTA) contracting parties to the European Economic Area (EEA), the EFTA State Switzerland, candidate states, the countries of the European Neighbour-hood Policy (ENP), and Russia. The European Court of Justice (ECJ) is the centre of gravity in the judicial dimension of this policy. The innermost circle of integration after the EU itself comprises the EFTA States who are party to the European Economic Area. With the EFTA Court, they have their own common court. The existence of two courts – the ECJ and the EFTA Court – raises the question of homogeneity of the case law. The EEA homogeneity rules resemble the ones of the Lugano Convention. The EFTA Court is basically obliged to follow or take into account relevant ECJ case law. But even if the ECJ has gone first, there may be constellations where the EFTA Court comes to the conclusion that it must go its own way. Such constellations may be given if there is new scientific evidence, if the ECJ has left certain questions open, where there is relevant case law of the European Court of Human Rights or where, in light of the specific circumstances of the case, there is room for “creative homogeneity”. However, in the majority of its cases the EFTA Court is faced with novel legal questions. In such cases, the ECJ, its Advocates General and the Court of First Instance make reference to the EFTA Court’s case law. The question may be posed whether the EEA could serve as a model for other regional associations. For the ENP states, candidate States and Russia this is hard to imagine. Their courts will to varying degrees look to the ECJ when giving interpretation to the relevant agreements. The Swiss Government is – at least for the time being – unwilling to make a second attempt to join the EEA. The European Commission has therefore proposed to the Swiss to dock their sectoral agreements with the EU to the institutions of the EFTA pillar, the EFTA Surveillance Authority (ESA) and the EFTA Court. Switzerland would then negotiate the right to nominate a member of the ESA College and of the EFTA Court. The Swiss Government has, however, opted for another model. Swiss courts would continue to look to the ECJ, as they did in the past, and conflicts should also in the future be resolved by diplomatic means. But the ECJ would play a decisive role in dispute settlement. It would, upon unilateral request of one side, give an “authoritative” interpretation of EU law as incorporated into the relevant bilateral agreement. In a “Non-Paper” which was drafted by the chief negotiators, the interpretations of the ECJ are even characterised as binding. The decision-making power would, however, remain with the Joint Committees where Switzerland could say no. The Swiss Government assumes that after a negative decision by the ECJ it would be able to negotiate a compromise solution with the Commission without the ECJ being able to express itself on the outcome. The Government has therefore not tried to emphasise that the ECJ would not be a foreign court. Whether the ECJ would accept its intended role, is an open question. And if it would, the Swiss Government would have to explain to its voters that Switzerland retains the freedom to disregard such a binding decision and that for this reason the ECJ is not only no foreign court, but no adjudicating court at all.

Cost sharing solutions defined by non-negative eigenvectors

The problem of sharing a cost M among n individuals, identified by some characteristic ci∈R+,ci∈R+, appears in many real situations. Two important proposals on how to share the cost are the egalitarian and the proportional solutions. In different situations a combination of both distributions provides an interesting approach to the cost sharing problem. In this paper we obtain a family of (compromise) solutions associated to the Perron’s eigenvectors of Levinger’s transformations of a characteristics matrix A. This family includes both the egalitarian and proportional solutions, as well as a set of suitable intermediate proposals, which we analyze in some specific contexts, as claims problems and inventory cost games.

The United Nations 'quasi-prosecutorial' investigative mechanisms: assessing a new institutional model in the international criminal justice landscape

This work aims to provide a theoretical examination of three recently created bodies of the United Nations mandated to investigate the alleged international crimes committed in Syria (IIIM), Iraq (UNITAD) and Myanmar (IIMM). Established as a compromise solution in the paralysis of international criminal jurisdictions, these essentially overlapping entities have been depicted as a ‘new generation’ of UN investigative mechanisms. While non-judicial in nature, they depart indeed from traditional commissions of inquiry in several respects due to their increased criminal or ‘quasi-prosecutorial’ character. After clarifying their legal basis and different mandating authorities, a comparative institutional analysis is thus carried out in order to ascertain whether these ‘mechanisms’ can be said to effectively represent a new institutional model. Through an in-depth assessment of their mandates, the thesis is also intended to outline both the strengths and the criticalities of these organs. Given their aim to facilitate criminal proceedings by sharing information and case files, it is suggested that more attention shall be paid to the position of the person under investigation. To this end, some proposals are made in order to enhance the mechanisms’ frameworks, especially from the angle of procedural safeguards. As a third aspect, the cooperation with judicial authorities is explored, in order to shed light on the actors involved, the relevant legal instruments and the possible obstacles, in particular from a human rights perspective. Ultimately, drawing from the detected issues, the thesis seeks to identify some lessons learned which could be taken into account in case of creation of new ad hoc investigative mechanisms or of a permanent institution of this kind.

Developing an aquaponics system to learn sustainability and social compromise skills

The goal of this project, one of the proposals of the EPS@ISEP Spring 2014, was to develop an Aquaponics System. Over recent years Aquaponics systems have received increased attention since they contribute to reduce the strain on resources within 1st and 3rd world countries. Aquaponics is the combination of Hydroponics and Aquaculture, mimicking a natural environment in order to successfully apply and enhance the understanding of natural cycles within an indoor process. Using this knowledge of natural cycles, it was possible to create a system with capabilities similar to that of a natural environment with the support of electronics, enhancing the overall efficiency of the system. The multinational team involved in the development of this system was composed of five students from five countries and fields of study. This paper describes their solution, including the overall design, the technology involved and the benefits it can bring to the current market. The team was able to design and render the Computer Aided Design (CAD) drawings of the prototype, assemble all components, successfully test the electronics and comply with the budget. Furthermore, the designed solution was supported by a product sustainability study and included a specific marketing plan. Last but not least, the students enrolled in this project obtained new multidisciplinary knowledge and increased their team work and cross-cultural communication skills.

Modell Deutschland as an Interdenominational Compromise, CES Germany & Europe Working Papers, No. 00.3, 2000

Usually, Germany’s social market economy is understood to embody a compromise between a liberal market order and a corporatist welfare state. While this reading of the German case is certainly not entirely wrong, this paper argues that only if we account for the close intellectual correspondence between lutheran Protestantism and economic liberalism on the one hand and between Catholicism and welfare corporatism on the other, can we fully comprehend the nature of the German post-war compromise. In particular, this perspective allows to better explain the anti-liberal undercurrents of Germany’s soziale Marktwirtschaft. It was especially the role which Protestant Ordoliberals ascribed to the state in upholding economic order and market discipline which accounts for the major difference between ‘classic’ and ‘German-style’ economic liberalism. Yet, the postwar economic order did not represent a deliberately struck compromise between the two major Christian denominations. Rather, Germany’s social market economy was the result of the failure of German Protestant Ordoliberals to prevent the reconstruction of the catholic Bismarckian welfare state after the authoritarian solution, which Ordoliberals had endorsed so strongly up until 1936 and from which they had hoped the re-inauguration of Protestant hegemony, had so utterly failed. Since the ordoliberal doctrine up to the present day lacks a clear understanding of the role of the corporatist welfare state within the German political economy, its insights into the functioning logic of German capitalism have remained limit. The paper also claims that accounting for the denominational roots of the postwar compromise allows us to better understand the relationship between consociationalism and corporatism in ‘Modell Deutschland’.
