The future obligations of "project manager" as construction integral director (DIPE) in the law of buildings construction in spain (LOE)

In the year 1999 approves the Law of Construction Building (LOE, in Spanish) to regulate a sector such as construction, which contained some shortcomings from the legal point of view. Currently, the LOE has been in force 12 years, changing the spanish world of the construction, due to influenced by internationalization. Within the LOE, there regulating the different actors involved in the construction building, as the Projects design, the Director of Construction, the developer, The builder, Director of execution of the construction (actor only in Spain, similar as construcion engineer and abroad in), control entities and the users, but lacks figure Project manager will assume the delegation of the promoter helping and you organize, direct and management the process. This figure assumes that the market and contracts are not legally regulated in Spain, then should define and establish its regulation in the LOE. (Spain Construction Law) The translation in spanish of the words "Project Manager is owed to Professor Rafael de Heredia in his book Integrated Project Management, as agent acting on behalf of the organization and promoter assuming control of the project, ie Integraded Project Management . Already exist in Spain, AEDIP (Spanish Association Integrated of Project Construction management) which comprises the major companies in “Project Management” in Spain, and MeDIP (Master in Integrated Construction Project) the largest and most advanced studies at the Polytechnic University of Madrid, in "Construction Project Management" they teach which is also in Argentina. The Integrated Project ("Project Management") applied to the construction process is a methodological technique that helps to organize, control and manage the resources of the promoters in the building process. When resources are limited (which is usually most situations) to manage them efficiently becomes very important. Well, we find that in this situation, the resources are not only limited, but it is limited, so a comprehensive control and monitoring of them becomes not only important if not crucial. The alternative of starting from scratch with a team that specializes in developing these follow directly intervening to ensure that scarce resources are used in the best possible way requires the use of a specific methodology (Manual DIP, Matrix Foreign EDR breakdown structure EDP Project, Risk Management and Control, Design Management, et ..), that is the methodology used by "Projects managers" to ensure that the initial objectives of the promoters or investors are met and all actors in process, from design to construction company have the mind aim of the project will do, trying to get their interests do not prevail over the interests of the project. Among the agents listed in the building process, "Project Management" or DIPE (Director Comprehensive building process, a proposed name for possible incorporation into the LOE, ) currently not listed as such in the LOE (Act on Construction Planning ), one of the agents that exist within the building process is not regulated from the legal point of view, no obligations, ie, as is required by law to have a project, a builder, a construction management, etc. DIPE only one who wants to hire you as have been advanced knowledge of their services by the clients they have been hiring these agents, there being no legal obligation as mentioned above, then the market is dictating its ruling on this new figure, as if it were necessary, he was not hired and eventually disappeared from the building process. As the aim of this article is regular the process and implement the name of DIPE in the Spanish Law of buildings construction (LOE)

Refined second law of thermodynamics for fast random processes

We establish a refined version of the Second Law of Thermodynamics for Langevin stochastic processes describing mesoscopic systems driven by conservative or non-conservative forces and interacting with thermal noise. The refinement is based on the Monge-Kantorovich optimal mass transport and becomes relevant for processes far from quasi-stationary regime. General discussion is illustrated by numerical analysis of the optimal memory erasure protocol for a model for micron-size particle manipulated by optical tweezers.

Prediction of bendig load capacity of timber beams by finite element method simulation of knots and grain deviation

A finite element model was used to simulate timberbeams with defects and predict their maximum load in bending. Taking into account the elastoplastic constitutive law of timber, the prediction of fracture load gives information about the mechanisms of timber failure, particularly with regard to the influence of knots, and their local graindeviation, on the fracture. A finite element model was constructed using the ANSYS element Plane42 in a plane stress 2D-analysis, which equates thickness to the width of the section to create a mesh which is as uniform as possible. Three sub-models reproduced the bending test according to UNE EN 408: i) timber with holes caused by knots; ii) timber with adherent knots which have structural continuity with the rest of the beam material; iii) timber with knots but with only partial contact between knot and beam which was artificially simulated by means of contact springs between the two materials. The model was validated using ten 45 × 145 × 3000 mm beams of Pinus sylvestris L. which presented knots and graindeviation. The fracture stress data obtained was compared with the results of numerical simulations, resulting in an adjustment error less of than 9.7%

Training organization of a middle-size company engaged in information technology services: theory and practice

In order to establish an active internal know-how -reserve~ in an information processing and engineering services . company, a training architecture tailored to the company as an whole must be defined. When a company' s earnings come from . advisory services dynamically structured i.n the form of projects, as is the case at hand, difficulties arise that must be taken into account in the architectural design. The first difficulties are of a psychological nature and the design method proposed here begjns wi th the definition of the highest training metasystem, which is aimed at making adjustments for the variety of perceptions of the company's human components, before the architecture can be designed. This approach may be considered as an application of the cybernetic Law of Requisita Variety (Ashby) and of the Principle of Conceptual Integrity (Brooks) . Also included is a description of sorne of the results of the first steps of metasystems at the level of company organization.

Technology of bare tether current collection

The outstanding problem for useful applications of electrodynamic tethers is obtaining sufficient electron current from the ionospheric plasma. Bare tether collectors, in which the conducting tether itself, left uninsulated over kilometers of its length, acts as the collecting anode, promise to attain currents of 10 A or more from reasonably sized systems. Current collection by a bare tether is also relatively insensitive to drops in electron density, which are regularly encountered on each revolution of an orbit. This makes nighttime operation feasible. We show how the bare tether's high efficiency of current collection and ability to adjust to density variations follow from the orbital motion limited collection law of thin cylinders. We consider both upwardly deployed (power generation mode) and downwardly deployed (reboost mode) tethers, and present results that indicate how bare tether systems would perform as their magnetic and plasma environment varies in low earth orbit.

Performance of bare-tether systems under varying magnetic and plasma conditions

Electrodynamic tethered systems, in which an exposed portion of the conducting tether itself collects electrons from the ionosphere, promise to attain currents of 10 A or more in low Earth orbit. For the first time, another desirable feature of such bare-tether systems is reported and analyzed in detail: Collection by a bare tether is relatively insensitive to variations in electron density that are regularly encountered on each revolution of an orbit. This self-adjusting property of bare-tether systems occurs because the electron-collecting area on the tether is not fixed, but extends along its positively biased portion, and because the current varies as collecting length to a power greater than unity. How this adjustment to density variations follows from the basic collection law of thin cylinders is shown. The effect of variations in the motionally induced tether voltage is also analyzed. Both power and thruster modes are considered. The performance of bare-tether systems to tethered systems is compared using passive spherical collectors of fixed area, taking into consideration recent experimental results. Calculations taking into account motional voltage and plasma density around a realistic orbit for bare-tether systems suitable for space station applications are also presented.

Change of extreme rainfall indexes at Ebro River Basin

The purpose of this work is to provide a description of the heavy rainfall phenomenon on statistical tools from a Spanish region. We want to quantify the effect of the climate change to verify the rapidity of its evolution across the variation of the probability distributions. Our conclusions have special interest for the agrarian insurances, which may make estimates of costs more realistically. In this work, the analysis mainly focuses on: The distribution of consecutive days without rain for each gauge stations and season. We estimate density Kernel functions and Generalized Pareto Distribution (GPD) for a network of station from the Ebro River basin until a threshold value u. We can establish a relation between distributional parameters and regional characteristics. Moreover we analyze especially the tail of the probability distribution. These tails are governed by law of power means that the number of events n can be expressed as the power of another quantity x : n(x) = x? . ? can be estimated as the slope of log-log plot the number of events and the size. The most convenient way to analyze n(x) is using the empirical probability distribution. Pr(X mayor que x) ? x-?. The distribution of rainfall over percentile of order 0.95 from wet days at the seasonal scale and in a yearly scale with the same treatment of tails than in the previous section.
