APPLICATION OF AGENT-BASED MODELING AND SIMULATION TO UNDERSTANDING COMPLEX MANAGEMENT PROBLEMS IN CEM RESEARCH
Authors: Son Jeongwook , Rojas Eddy M. , Shin Seung-Woo
Published: November 2015

As construction projects have become larger and more complex, they develop different features than smaller or traditional projects, which characterize them as complex systems. Still, Construction Engineering and Management (CEM) researchers have mostly relied on traditional approaches to investigate complex management problems, which might produce misleading results. This paper introduces Agent-Based Modeling and Simulation (ABMS) as a research method, and addresses how it could be applied to CEM research. With an illustrative example of the application of ABMS to CEM research, the theoretical background as well as the design, development, and test processes of ABMS are presented. We then made a recommendation on the promising research subjects in CEM area to which ABMS could be suitably applied.
PRACTITIONERS’ PERCEPTION OF VALUE IN CONSTRUCTION
Authors: Wandahl Søren
Published: November 2015

Value delivery is basically the main purpose of construction, and in fact it is not the physical construction in itself that a client buys but the attributes or value the building provides. This value delivery is undertaken in a complex endeavour of collaboration. Throughout a building project value is in focus both implicit and explicit. Often challenges or direct problems arise during the process, which may be due to an incongruent perception of value. A survey was conducted among practitioners of the Danish building industry, aiming at investigating whether or not practitioners perceive value differently. The survey revealed that the practitioners had a diverse understanding of how to perceive value in a building project. This is problematic for the efficiency and effectiveness of building projects. Value is the underlying concept of emerging methods and concepts such as Lean Construction, Value Management and Partnering. When a homogeneous understanding of value does not exist, the full potential of applying value based concepts will not occur.

Authors: Marcinkowska Ewa , Gawron Krzysztof , Rejment Mariusz
Published: November 2015

In the paper the authors examined the relations between the physical deterioration degree and the price of the tenement-houses in Wrocław. The researches concern the year’s 1991–2009. According to the following analyses: technical, technical-economic (concerning the relations between buildings technical condition and buildings price) and economic the authors have come the conclusions concerning the sensibility of the revitalization work. The authors also estimated the purchase limit profitability of the tenement-houses, which are going to be repaired and modernized or to be demolished and next to be built a new tenement-house. The direction of the engineering activities was shown. They could improve the economic effectiveness of the revitalized tenement-houses.
EVALUATION OF EXCAVATOR TECHNOLOGIES: APPLICATION OF DATA FUSION BASED MULTIMOORA METHODS
Authors: Altuntas Serkan , Dereli Turkay , Kemal Yılmaz Mustafa
Published: November 2015

Excavators are quite expensive vehicles. Therefore, there may be huge losses for decision makers if a wrong decision is made during the purchasing process. A good evaluation of excavator alternatives both reduces costs and increases the benefits the excavator for the purchaser. The aim of this study is to prioritise excavator technologies to help decision makers during the purchasing process and to apply three different “data fusion methods” instead of the “theory of dominance” of the original MULTI MOORA method. The MULTI MOORA method is composed of three methods, namely: the ratio analysis as a part of MOORA, Reference Point Theory (the reference point approach as a part of MOORA) and the Full Multiplicative Form. It is used to prioritise excavator technologies in this study. The MULTI - MOORA method combines three results obtained from these three methods using the theory of dominance. Dominance directed graph, Rank position method and Borda count method as data fusion methods are also used to combine these three results instead of the “theory of dominance”. The results from this study show that there is no difference between the data fusion methods and the MULTI MOORA method can be applied to technology evaluation of the excavator alternatives successfully.
THE MULTICRITERIA ASSESSMENT OF THE SPATIAL PLANNING PROCESS: THE ASPECT OF INVESTMENT
Authors: Komarovska Andželika , Ustinovichius Leonas , Peckienė Aurelija
Published: November 2015

The effectiveness of an investment determined by the macroeconomic situation of a country stimulates national macroeconomic development. The principles of sustainable development must be followed in order to effectively organize the spatial planning process. To ascertain the efficiency of the legal base of Lithuanian spatial planning, a comparison of the Lithuanian spatial planning organization process with those carried out in Poland and Germany has been performed. For this purpose, the basic principles of spatial planning legislation have been analyzed. The challenge was addressed to the analysis of the verbal spatial planning system. Verbal decision-making system UniComBOS (Unit Comparison for the Best Selection Object) is used for determining a model for an effective spatial planning system. The modified concept of the spatial planning model is suggested in accordance with the results obtained in the run of the carried out analysis.
REINFORCEMENT OF LAMINATED GLASS FACADES AGAINST THE BLAST LOAD
Authors: Nakhaei Jalal , Forghani Saeed , Bitarafan Mahdi , Arefi Shahin Lale , Šaparauskas Jonas
Published: November 2015

The first defensive element of the building against the explosion is the façade. On the condition that façade is not resistant against explosion and encounters the damage, the blast wave will enter the construction and increases financial losses and casualties. With respect to that glass facades do not possess adequate strength under the explosion; the major aim of the study is to examine variety of the reinforcement practices of glazing facades with the laminated glass subjected to the blast wave. The investigation has been done by two descriptive and simulation approaches with the finite element software of AutoDyn and eight simulations has been represented in the subject of laminated glasses. In addition, through AHP method, related questionnaires were designed so that some experts including 31 people possessing the activity and investigation background of two to thirty years in the civil protection scope answered them. Considered indexes in AHP model consist of resistance against explosion, passed light rate, expenditure, complexity and difficulty of accomplishment so that in the resistance part versus explosion, the results of numerical simulation have been benefited. Outcomes demonstrate the best function in laminated glass models belongs to the overlapped louvered opening model. Afterwards, the model of two-layer laminated glass with the spring is laid. Furthermore, the most economical model which supplies the most light as well as the most safety is the model of one-layer laminated glass with spring.

Siegfried Kracauer, De Caligari à Hitler (1947)
Authors: Kleinberger Alain
Published: November 2015

De Caligari à Hitler, sous-titré « Une histoire psychologique du cinéma allemand », a longtemps été le texte le plus connu de Siegfried Kracauer. Il passait auprès des amateurs et des cinéphiles pour être l’ouvrage de référence du cinéma expressionniste allemand, et la plupart des anthologies des années 1970 reprennent les pages fortement documentées qu’il consacre au célèbre film de Robert Wiene. Force est de constater qu’il n’en va plus tout à fait ainsi aujourd’hui, après qu’il a été l’objet de critiques assez vives, à l’heure où son livre n’est même plus disponible en français, en France.
Dialectique négative et/ou dialectique matérielle : retour sur le débat Adorno/Kracauer
Authors: Chanson Vincent
Published: November 2015

Les deux dernières rencontres entre Kracauer et Adorno dans les années 1960 sont l’occasion d’une ultime mise au point dont l’enjeu est précisément de reconstituer la portée philosophique d’un compagnonnage et d’une fidélité jamais démentis depuis la fin des années 1910. L’occasion surtout de prendre toute la mesure de la portée de deux gestes conceptuels, à la fois profondément liés et profondément différents, revendiquant tous deux leur statut matérialiste : celui, kracauerien, portant le nom de dialectique matérielle , et consistant en une micrologie attentive aux singularités, et celui, adornien, de la dialectique négative , assumant dans le même mouvement « primat de l’objet » et « procès dialectique maintenu ».
Tempo de la vie d’artiste : genre et concurrence des temps professionnels et domestiques
Authors: Sinigaglia-Amadio Sabrina , Sinigaglia Jérémy
Published: November 2015

La vie d’artiste peut se caractériser par une double concurrence des temps : d’une part au sein de l’espace professionnel (entre les activités de création, d’administration, de communication, d’enseignement, etc .) ; d’autre part entre celui-ci et l’espace domestique. L’article propose d’analyser les conditions et les modalités de l’articulation des temps de travail et des temps de vie d’artistes musicien·ne·s et plasticien·ne·s. Il montre notamment que cette articulation repose sur des arrangements implicites qui correspondent à une mise en conformité avec des normes sociales mobilisant des repères dominants de la distribution des temps et des tâches sociales qui sont des impensés des rapports sociaux, impliquant des inégalités sociales et professionnelles, d’une part ; des inégalités de genre, d’autre part.
Par-delà l’antagonisme et l’accord. Essai de théorie de la violence extrême
Authors: Sigalas Nicos
Published: November 2015

Notre expérience de la politique bute constamment sur la violence, qui constitue, selon deux conceptions qui s’opposent tout en s’enchevêtrant, aussi bien la limite de la politique que son centre occulté (voire occulte). Il devient donc nécessaire, et même urgent de revisiter les catégories dont nous disposons pour comprendre la violence. Nous revisitons ici trois discours philosophiques modernes qui tiennent un rôle prépondérant dans notre conception de la politique : la philosophie politique, l’économie politique et la philosophie de l’histoire. Ils constituent en même temps trois modes différents de formulation du problème de la violence. Ces discours, nous essayons de les mettre en rapport avec deux traditions (ou directions) opposées, que nous supposons être à l’origine de la pensée politique moderne. Nous les appelons tradition de l’anti-domination et tradition de la légitimité. Enfin dans la même topique nous situons les deux formes de violence distinguées par Balibar dans son livre Violence et civilité  : la violence ultra-subjective et la violence ultra-objective.
Problème d’expression de l’unité de la société politique : Balibar et Spinoza
Authors: Eksen Gaye Çankaya
Published: November 2015

Dans l’étude présente, à partir de la lecture de quatre textes de Balibar qui se réfèrent à la question de l’individualité, nous nous proposons de montrer que Balibar n’hésite pas à attribuer une certaine individualité aux sociétés politiques en se basant sur la philosophie de Spinoza. À partir du fait que Balibar fait l’usage d’une terminologie spécifique de l’individualité qui sert à élaborer l’existence collective des individus humains, nous voudrions discuter la possibilité d’utiliser une autre terminologie pour exprimer l’unité des peuples, ou des sociétés politiques, à part de toutes les variations du terme « Individu ». La sortie de la terminologie de l’individualité, quant à l’analyse des sociétés politiques chez Spinoza, peut nous aider pour construire une conception plus légitime, croyons-nous, de la particularité de chaque société politique qui se montre comme la manifestation d’une certaine manière d’exister et d’agir ensemble.
La temporalité et la civilité chez Balibar
Authors: Özdemir Seçkin Sertdemir
Published: November 2015

Quand Étienne Balibar s’interroge sur la relation ambiguë entre la violence et la politique dans son livre intitulé Violence et civilité, il examine en effet à la fois le côté tragique propre au domaine politique et la possibilité de l’action qui se manifeste dans un espace propre à soi. Mais dans cette analyse, s’agit-il seulement une définition spatiale de la politique et de l’action ? Si toute réflexion spatiale de la politique modèle en effet une temporalité propre, comment peut-on penser la temporalité de la « civilité » dans le livre de Balibar, Violence et civilité ? Dans cette intervention, j’explique l’analyse temporelle du concept de « civilité » à partir de son article intitulé « Trois concepts de la liberté : émancipation, transformation, civilité ».
Au-delà de la violence institutionnelle et insurrectionnelle : Balibar, Arendt et l’ agon
Authors: Gambetti Zeynep
Published: November 2015

Étienne Balibar se réfère à l’idée arendtienne de la citoyenneté pour montrer que la démocratie se construit nécessairement au travers d’une aporie. D’une part, la démocratie évoque l’idéal isonomique de l’égalité pour fonder la communauté ; d’autre part, elle inscrit la différence dans l’éventualité d’une contestation permanente des principes unificateurs. Ce que je propose, c’est de contribuer à développer le dialogue entre É. Balibar et Hannah Arendt en m’interrogeant sur la possibilité d’aller au-delà de l’horizon de la violence. Le concept d’ agon qu’Arendt utilise pour qualifier le vivre ensemble isonomique n’est pas la concurrence entre artisans, ni le conflit entre ennemis, mais renvoie plutôt à l’institution d’un monde commun grâce aux différences. L’agir agonistique comprend le risque de se distinguer, d’être en désaccord, de se différer, non seulement par rapport aux autres, par un souci de scientificité, mais aussi par rapport à soi-même. Il faudrait alors définir la violence comme une force qui agit sur l’ agon , c’est-à-dire, sur la capacité de « devenir-autre ». C’est justement ceci, et aussi bien la loi que la notion moderne de droits oblitère.
Violence sociale et crise du sujet : flexibilité, précarité politique
Authors: Possenti Ilaria
Published: November 2015

Aujourd’hui, il n’est pas rare que le nouveau capitalisme financier engendre des processus de destructuration continuelle des entreprises et du travail, et que les stratégies et les politiques de l’emploi finissent par devenir absurdes. La précarité actuelle oscille entre une violence sociale ordinaire, intimement liée à des problèmes d’exploitation et de profit, et une violence sociale exceptionnelle, agressive qui constitue un frein aux procès de subjectivisation politique, rendant extrêmement difficile la production de résistances. Il faut alors s’interroger sur la « flexibilité » actuelle qui est une triple forme de précarité (materielle, sociale et cognitive), et qui, comme dispositif de pouvoir, relie entre eux des discours et des pratiques complexes. Dans cette perspective, le mot « flexibilité » ne fait plus référence à la « plasticité personnelle » (cf. William James, John Dewey, Gregory Bateson, la critique sociale et féministe du travail fordiste). Bien au contraire, le dispositif de flexibilité renvoie aux aspects coercitifs et destructeurs d’une condition où la plasticité personnelle est foulée au pied, tantôt selon des modalités caractéristiques de l’époque post-fordiste, tantôt selon des modalités néo tayloriennes. Contrairement aux dispositifs sur lesquels réfléchissait Michel Foucault, le dispositif de flexibilité ne produit pas de sujets qui lui soient propres, il ne les définit d’aucune façon. Il s’emploie au contraire à les détruire après les avoir conçus. En effet, la flexibilité actuelle renvoie à des processus de désubjectivisation ou de précarisation des sujets, et nous oblige à poser des questions par rapport au concept de « violence extrême ».
Le ciblage d’inflation dans les économies émergentes
Authors: Lucotte Yannick
Published: November 2015

Depuis son adoption par la Nouvelle-Zélande en 1990, le ciblage d’inflation a connu un succès grandissant auprès des banques centrales, particulièrement au sein des économies émergentes. On dénombre aujourd’hui 26 pays cibleurs d’inflation, dont près des trois quarts sont des émergents. Malgré des résultats encourageants, son adoption par cette catégorie de pays pose toujours un certain nombre de questions étudiées de près dans la littérature académique. L’objectif de cet article est de passer en revue les débats qui entourent l’adoption et la conduite d’une politique de ciblage d’inflation par les pays émergents. Une place toute particulière est accordée à la question du cadre institutionnel, en analysant dans quelle mesure ce dernier a pu jouer sur la crédibilité et les performances de cette stratégie de politique monétaire au sein des économies émergentes.
L’épargnant propriétaire face à ses vieux jours
Authors: Masson André
Published: November 2015

Près des trois quarts des épargnants seniors français sont propriétaires de leur logement. Tout en restant chez eux jusqu’à leur décès, ils pourraient rendre liquide ou mobiliser leur patrimoine immobilier pour financer les besoins d’une durée de retraite de plus en plus longue. Les produits viagers gagés ainsi sur le logement sont cependant peu diffusés. Le viager traditionnel sur les marchés de gré à gré, où le vendeur et l’acheteur sont tous deux des particuliers, souffre d’une image désuète et d’une réputation peu flatteuse. Le prêt viager actuel présente des inconvénients majeurs tant du côté de la demande, parce qu’il met sous tension les relations familiales, que du côté de l’offre, parce que, contracté trop tôt, il porte sur des espérances de vie trop longues. Notre analyse montre tout d’abord comment la rationalité pratique de l’épargnant contribue à expliquer, pour des raisons différentes, la faible demande de la rente viagère et des produits viagers gagés sur le logement. Elle propose ensuite deux nouveaux produits, mieux adaptés à cette rationalité : le viager mutualisé, que nous appellerons « viage », est censé remédier à nombre d’inconvénients du viager traditionnel grâce à une offre d’achat institutionnelle bien régulée ; le prêt viager-dépendance réversible, accordé seulement en cas de dépendance dûment constatée, constituerait une alternative crédible à l’assurance dépendance. Dans les deux cas, on précise les conditions, juridiques, fiscales et institutionnelles, qui permettraient la diffusion du produit à une échelle significative.
Intravitreal Aflibercept for Neovascular AMD: Short-Term Clinical Effects of Intravitreal Aflibercept Injection as a Predictor of Long-Term Results
Authors: Liu Enchun M. , Shah Gaurav , Blinder Kevin J. , Smith Bradley T. , Thomas Matthew A.
Published: November 2015

BACKGROUND AND OBJECTIVE:

To study the relationship between early response to intravitreal aflibercept injection (IAI) for neovascular age-related macular degeneration (nAMD) and long-term visual outcomes

PATIENTS AND METHODS:

Seventeen patients with nAMD participated in this prospective clinical trial. All patients received three initial monthly IAIs, followed by IAIs at 8-week intervals. Study visits were scheduled at 1 week, followed by every 2 weeks for the first 3 months and then every 4 weeks until the conclusion of the study at 48 weeks.

RESULTS:

Eight eyes (47%) were dry on spectral-domain optical coherence tomography by week 2 (early responders), and the remaining nine eyes took an average of 7.5 weeks for fluid resolution (late responders). The mean change in best-corrected visual acuity (BCVA) at the final visit was +11.9 letters from baseline (
P
= .002). Average BCVA gain in early responders was +11.6 letters compared to +12.2 letters in late responders (
P
= .7).

CONCLUSIONS:

Although there was not a statistically significant correlation between early response to IAI and better long-term outcomes, both early and late responders maintained excellent visual outcomes at 48 weeks.

ReSure Sealant for Pars Plana Vitrectomy Wound Closure
Authors: Ho Vincent Y. , Shah Gaurav K. , Liu Enchun M.
Published: November 2015

BACKGROUND AND OBJECTIVE:

ReSure Sealant (Ocular Therapeutix, Bedford, MA) is an ocular sealant that demonstrated both safety and effectiveness in a prospective, randomized clinical trial for sealing clear corneal incisions following cataract surgery and intraocular lens placement in adults.
1

PATIENTS AND METHODS:

This is the first literature report of ReSure Sealant used for the closure of 23-gauge (G) pars plana vitrectomy (PPV) sclerotomies. A 70-year-old pseudophakic female with a history of epiretinal membrane and branch retinal vein occlusion of the right eye underwent 23-G PPV, membrane peel, and air-fluid exchange and was found to have leaking subconjunctival air at the end of the case. A linear conjunctival incision was performed to access the sclerotomy site. The incisions were then carefully dried before the sealant was applied to seal both the sclera and conjunctiva.

RESULTS:

After polymerization, the sealant formed a polyethylene glycol (PEG) hydrogel that was 89% water and 9.44% PEG. PEG is a synthetic material that is non-toxic and inert and, thus, suitable for use in medical products.

CONCLUSION:

ReSure Sealant may be a safe, quick method to close sclerotomy wounds in select cases.

Intraocular Nematode Affixed to Posterior Lens Capsule
Authors: Karth Peter A. , Swinney Christian C. , Moshfeghi Darius M. , Yannuzzi Lawrence A. , Pang Claudine E. , Leng Theodore
Published: November 2015

The clinical presentation of an intraocular nematode unusually affixed to the posterior lens capsule is described. A 64-year-old female patient presented with a 7-year history of gradually declining vision and enlarging central scotoma, but no inflammation. On follow-up 2 years later, vision had further declined and a non-motile, 8-mm nematode was seen affixed to the posterior lens capsule that remained unchanged through final follow-up. The patient disclosed having resided in Africa as a child. Systemic review revealed no evidence of extraocular involvement. Nematode carcasses may remain preserved in the human eye for extended periods without ongoing inflammation.

Los otros noruegos de Caneliñas: la campaña ballenera de 1929
Authors: Valdés  Hansen Felipe
Published: November 2015

El préstamo al autor de un documento inédito de la Compañía Ballenera Española, el libro de salarios de 1929, ha revelado nuevos datos sobre la actividad de los balleneros noruegos en Galicia en el siglo XX. Ello exige actualizar lo que sabíamos sobre su presencia en la factoría de Caneliñas, donde interrumpieron la actividad en 1927 ante la disminución de capturas (sobre todo en el estrecho de Gibraltar), la consiguiente caída de los beneficios y el aumento de los costos de explotación; además del interés de los directivos noruegos por trasladar el marco de operaciones al Antártico. El fracaso en 1928 de la Compañía Ballenera Internacional, que tenía previsto mantener operativa la factoría, marcó el destino a corto plazo de Caneliñas. Sin embargo, ahora sabemos que en 1929 la factoría fue reactivada breve y coyunturalmente al recalar allí la flota adquirida ese año por S. Foyn Bruun y A. von der Lippe, antes de unirse a su nueva factoría flotante (el Pontos) y partir rumbo al Antártico. Esta nueva fuente ha aportado valiosa información de la que carecíamos, como la organización del trabajo, la relación nominal de los trabajadores noruegos, sus salarios o las primas por captura y producción entre otros datos.

Characterization of Western Painted Turtle Bycatch in Fyke Nets During Freshwater Fish Population Assessments
Authors: Moos Tyrel S. , Blackwell Brian G.
Published: November 2015

In fisheries management, fish populations are assessed using various net types that invariably also capture nontarget species. Although the bycatch of turtles tends to be a common occurrence, data describing the bycatch of turtles during freshwater fish sampling are lacking. To improve the available knowledge base concerning the bycatch of turtles during fish sampling, we characterize the dynamics of western painted turtle Chrysemys picta bellii bycatch in unbaited modified fyke nets used in fish population sampling in northeastern South Dakota. We collected data from June to September during fish population assessments in 39 lakes and nine impoundments between 2007 and 2012. We characterize western painted turtle bycatch relating to water type (lake and impoundment) including catch rates (number of turtles/net night), size structure, and sex ratio. Catch rates were higher in impoundments than lakes. Total mean annual catch rates ranged from 1.07 to 3.28 for lakes and from 0.70 to 6.63 for impoundments and the variation among years was significant for both water types. We observed no annual variation in water surface area or mean depth, precluding either from explaining the variation in annual catch rates. We observed a significant relationship between mean depth and catch rate for lakes, but not impoundments. We observed no significant relationship relating surface area to catch rate for lakes or impoundments. Catch rates differed significantly from June to September for lakes but not impoundments. Annual variation in catch rates was best explained by the previous winter precipitation for both water types. The sex ratio was skewed toward males and differed significantly from June to September for lakes but not impoundments. The size structure was skewed toward large turtles. Understanding bycatch dynamics during fish population assessments is a critical first step to understanding the impact of biological sampling on nontarget species and may prove useful in minimizing future bycatch of western painted turtles.
Still searching for graves: an analytical strategy for interpreting geophysical data used in the search for “unmarked” graves
Authors: Gaffney C. , Harris C. , Pope‐Carter F. , Bonsall J. , Fry R. , Parkyn A.
Published: November 2015

Searching for and mapping the physical extent of unmarked graves using geophysical techniques has proven difficult in many cases. The success of individual geophysical techniques for detecting graves depends on a site‐by‐site basis. Significantly, detection of graves often results from measured contrasts that are linked to the background soils rather than the type of archaeological feature associated with the grave. It is evident that investigation of buried remains should be considered within a 3D space as the variation in burial environment can be extremely varied through the grave. Within this paper, we demonstrate the need for a multi‐method survey strategy to investigate unmarked graves, as applied at a “planned” but unmarked pauper’s cemetery. The outcome from this case study provides new insights into the strategy that is required at such sites. Perhaps the most significant conclusion is that unmarked graves are best understood in terms of characterization rather than identification. In this paper, we argue for a methodological approach that, while following the current trends to use multiple techniques, is fundamentally dependent on a structured approach to the analysis of the data. The ramifications of this case study illustrate the necessity of an integrated strategy to provide a more holistic understanding of unmarked graves that may help aid in management of these unseen but important aspects of our heritage. It is concluded that the search for graves is still a current debate and one that will be solved by methodological rather than technique‐based arguments.
Integrated geophysical investigations at a sacred Hittite Area in Central Anatolia, Turkey
Authors: Drahor Mahmut G. , Berge Meriç A. , Öztürk Caner , Ortan Buket
Published: November 2015

In this paper, an integrated geophysical investigation of a sacred area in the archaeological site of Šapinuwa is presented. Šapinuwa was one of the important cities in the Hittite Empire. The archaeological site of Šapinuwa is located in the Çorum region of Central Anatolia, Turkey. The goal of the here presented integrative archaeological prospection investigation was to explore buried structures inside the so‐called sacred Taşdöşem area (Taşdöşem means “the stone pavement”) by employing a number of different near‐surface geophysical prospection methods. To this purpose, magnetic gradiometry, ground‐penetrating radar, electrical resistivity tomography, seismic refraction tomography, and multi‐channel analysis of surface wave tomography were applied in this specific area. Overall, the results of the individual geophysical investigations were superimposed in order to obtain more detailed and comprehensive integrative interpretations on the burials contained inside this sacred area. Electrical tomography depth slices revealed the presence of an important structure buried inside the Taşdöşem area. Surprisingly, the velocity variations observed in the depth slices of the multi‐channel analysis of surface wave tomography provided important information on the character of the burial structure. Additionally, seismic refraction tomography sections and depth slices confirmed the presence of the structures in the same locations. The result of the ground‐penetrating radar investigation did not present sufficient certainty regarding the possible deeper burials, whereas the magnetic gradiometry survey gave some insight into near‐surface structures. The combination of the employed geophysical prospection techniques was successfully able to characterize the structures that are assumed to have been buried within the Taşdöşem area. It is concluded that the integrated non‐invasive geophysical archaeological prospection study conducted at Šapinuwa provides a good example on how to approach the investigation and documentation of sites similar to the Taşdöşem.
Chasing aeroplanes: developing a vehicle‐towed caesium magnetometer array to complement aerial photography over three recently surveyed sites in the UK
Authors: Linford‐X. Neil , Linford Paul , Payne Andy
Published: November 2015

Aerial photography combined with airborne lidar can often provide information on the location of archaeological sites at a near landscape level of coverage. Ground‐based geophysical techniques may then be deployed to complement the aerial survey, particularly where the soils or land use may not be ideal for either producing crop marks or preserving topographic features. This paper describes the development of a vehicle‐towed caesium magnetometer array, from an original hand‐pushed system, to allow high‐density datasets to be rapidly acquired over large areas required to provide a meaningful comparison at the scale demanded by the aerial survey results. Technical details of the system are presented together with methodological considerations for both data acquisition in the field and appropriate post processing to obtain high‐sensitivity field measurements over more weakly magnetized sites. Results are presented from a number of recent collaborative research projects within the English Heritage Remote Sensing Team to illustrate the benefits of a combined aerial and ground‐based approach to mapping the historic environment.

Published: November 2015

This work explores the applicability and effectiveness of electrical resistivity tomography in mapping archaeological relics in the shallow marine environment. The approach consists of a methodology based on numerical simulation models validated with comparison to field data. Numerical modelling includes the testing of different electrode arrays suitable for multi‐channel resistivity instruments (dipole–dipole, pole–dipole, and gradient). The electrodes are placed at fixed positions either floating on the sea surface or submerged at the bottom of the sea. Additional tests are made concerning the resolving capabilities of electrical resistivity tomography with various seawater depths and target characteristics (dimensions and burial depth of the targets). Although valid a priori information, in terms of water resistivity and thickness, can be useful for constraining the inversion, it should be used judiciously to prevent erroneous information leading to misleading results. Finally, an application of the method at a field site is presented not only for verifying the theoretical results but also at the same time for proposing techniques to overcome problems that can occur due to the special environment. Numerical and field electrical resistivity tomography results indicated the utility of the method in reconstructing off‐shore cultural features, demonstrating at the same time its applicability to be integrated in wider archaeological projects.
3D inversion of ERT data on an archaeological site using GPR reflection and 3D inverted magnetic data as a priori information

Non‐destructive geophysical prospecting methods are increasingly used for the investigation of archaeological sites, where a detailed physical and geometrical reconstruction of structures is required prior to any excavation work. In 1996, at the Archaeological Test Site of the Sabine Necropolis at Research Area of National Research Council of Rome (Montelibretti, Italy), a small area had been selected to test the integration of magnetic, ground‐penetrating radar, and electrical resistivity tomography techniques.

The magnetic data were acquired as the vertical gradient of the total magnetic field and were inverted by minimizing an L‐2 norm. The ground‐penetrating radar data were acquired as single‐offset measurements on a regular grid and processed to obtain time slices of reflection amplitude. The electrical resistivity tomography data were acquired with dipole–dipole array along parallel profiles in both east–west and north–south directions.

In this work, we reprocessed the data collected in 1996 performing a three‐dimensional inversion of electrical resistivity tomography data using ground‐penetrating radar data and three‐dimensional inversion results of the magnetic data. We inverted electrical resistivity tomography data according to L2 and L1 norm minimization. Both the mean apparent resistivity and different resistivity distributions derived from processed ground‐penetrating radar and three‐dimensional inversion of the vertical gradient of the total magnetic field data were used as a starting model.

The results were then compared in the volume under the surveyed area: merits and shortcomings of the different techniques are pointed out and analyzed.

From the results of the different applied techniques, it comes that both electrical resistivity tomography and vertical gradient of the total magnetic field locate the searched tomb as a volume, whereas ground‐penetrating radar mainly identified the ceiling of the tomb. Vertical gradient of the total magnetic field data inversion obtained from minimization of the L2 norm properly locates both the chamber and the corridor but produces smeared overestimated volumes. Three‐dimensional inversions of electrical resistivity tomography data with a priori information give an accurate picture of the chamber and delineates the corridor, even if the resistivity values are underestimated if compared with the expected resistivity of void. Results are compared with the archaeological findings as the area was unearthed and verified in 2001.
Propriété foncière et propriété du capital en AlgérieLe foncier agricole, de l’autogestion à la concession
Authors: Belhimer Ammar
Published: November 2015

Longtemps ignorée, la propriété privée retrouve sa pleine consécration suite à des contraintes budgétaires induites par le choc pétrolier de 1996. Le désengagement de l’État de la sphère économique a fini par aboutir à une privatisation de plus en plus assumée dont le couronnement sera inscrit dans l’article 37 de la Constitution de 1996 consacrant la liberté de commerce et d’industrie. Le processus n’obéit cependant pas à une maturation socio-économique interne mais à des injonctions externes qui se faisaient de plus en plus pressantes au lendemain de l’accord de confirmation conclu avec le Fonds monétaire international en mai 1994. Le dispositif de privatisation entrepris sous le contrôle périodique de performance exercé par les experts du Fonds monétaire international reste toutefois fortement affecté par les pesanteurs administratives et bureaucratiques internes puisque le rôle de l’Etat répartiteur de rente et superviseur de l’accumulation privée – qu’il s’agisse de la sphère foncière, commerciale ou industrielle – n’en demeure pas moins essentiel. Si un tel schéma arrive à son terme, jamais bourgeoisie n’aura été aussi organiquement liée à un État paradoxalement volontariste et anticapitaliste.

Published: November 2015

The complex variable nature of the milling process complicates the scientific effort to understand it. Most scientific papers in this domain have focused on giving a particular solution for a specific subject of study, like: tool life, cutting forces, obtained surfaces after machining and so on. However a systematical analytical method for developing end milling cutter tools has not been found in the current literature. The main goal of this paper is to introduce and to give a general overview in the field of developing end milling cutters. The step-by-step approach focuses on the main element of a cutting tool: material, coating and geometry. Through an analytical study of the development of end milling cutters all elements in the design, manufacturing and testing have been taken into consideration. Such a method can be implemented when trying to analyze and summarize the research in the field of end milling cutters. The current paper is a preliminary evaluation in the development of end milling cutters. Further research will be accomplished in partnership between the Technical University of Cluj-Napoca and tool company Gühring KG.
Study on Minimum Quantity Lubrication Systems in Cooling of Machining Processes
Authors: Olaru Ionel , Nedelcu Dragoş Iulian
Published: November 2015

The cooling systems on machine tools are particularly important; these have a positive influence on the cutting operation and the quality of machined surface. A particular importance represent finding an optimal correlation between the lubricant and coolant used, the material to be processed, processing method and the cutting regime. A high temperature in the working area over a certain value allowable can be harmful in terms of both the resulted surface quality and repercussions on the life of the cutting tool. The parameters of the cooling-lubricating fluid flow can be influenced by the nature of the fluid or fluids, or the nozzle geometry used, which generally has a convergent-divergent geometry in order to achieve a better dispersion of the coolant/lubricant on the area to be machined.

Published: November 2015

Some of the aspects of the vehicle suspension limiting performances from stress and vibrations point of view have been explored in this study. The vehicle is modeled as two DOF system and the suspension is considered a passive one. 3D CATIA model was built for both the spring and spring-damper ensemble, neglecting the tire influence. This can reasonably covers the studies of geometries and forces (bending or tensile stress), masses and stiffnesses (meaning vibration profiles). The theoretical analysis on the vibration behaviour of the spring-damper ensemble, regarded as the vehicle suspension, suggests a convenient operation regime at low frequencies below 15 Hz, if the damper piston displacement is limited.

Published: November 2015

In the paper, the problem of designing of mechatronic discrete systems for vibration control has been investigated and generalized. As the design method, the synthesis has been used. Main focus of the paper is given to formalization of the mechatronic structures that contains elements with negative values on different stages of the synthesis process. The study is done based on different distributions methods of dynamical characteristics, dimensionless transformation and retransformation algorithm, simultaneously with verification of possible configurations of connections of piezostack actuators with external electric networks. As the result, various classifications of mechatronic discrete systems and general design constrains have been presented and discussed.

Published: November 2015

In this paper it is developed a location model for the infrastructures dedicated to non-motorized movements by bike in Oradea city, using ArcGIS geographic and information system [3]. They are taken into consideration the movements made by the target people – alternating movements (from home to school) and optional movements (made for recreation), the densities in residential areas, the type of the city arteries and the mobility need of the target people (in this case – young people aged between 15 and 25) in order to design two structures of the transport infrastructure networks (one for the alternating movements and the other for the optional movements), structures which will be realized on the actual frame of the existing transport infrastructure in Oradea city. Using Dijkstra algorithm, the minimal routes for the movements related to the alternating mobility, but also for the movements specific to the optional mobility are determined. Further on the most used arteries in the two structures of urban infrastructure networks are determined. The paper suggests as a solution the structure of the network for the non-motorized movements and also those arteries that must be used for its development, that guarantee gains for the target people (time), for the main operators who exploit the motorized systems, for the local budget of the local municipalities (less funds to sustain the public services) and especially for the environment and people’s health (attenuation of noxious and phonic pollution, reduction of the accidents’ number and health improvement).
