Published: July 2016

Abstract
An analysis of the shielding effectiveness by the method of dual transversal electromagnetic cell is proposed for a set of conductive materials of the type wire-inserted textiles. Based on the experimental results, some of the materials are further on used to test their capability to effectively reduce the specific absorption rate of energy deposition in the head due to mobile phone, when they are covering the surface of the handset. It is demonstrated that both reducing and increasing the radiation that penetrates the head may appear, and this depends on both the material structure, its position and orientation relative to the device and to the frequency band the phone is emitting.

Abstract
Screening is one of the main ways to achieve the Electromagnetic Compatibility (EMC) in the electric and electronic devices and equipments onboard a vessel. The present paper analyses the results of certain measurements made in order to determine the screen efficiency from the point of view of damping the induction magnetic field. Starting from the calculus for the screen efficiency, measurements of the intensity and level of the electric field, of the power density, of the damping and of the screening factor were made. These measurements were made both in the presence and in the absence of the screen.

Authors: Szabolcsi Róbert 
Published: July 2016

Abstract
The UAV pilot/operator training is a crucial part being evaluated during certification of the unmanned aircraft systems (UAS). There are many milestones behind, many new initiatives are launched. However, many initiatives originated to the type of the crew training and certification originated to that of the minimum levels derived by regulations. There are two main approaches when establish a training organization. First is, the so-called approach of minimums (AoM) delivered to the operators. Second is originated to that of the set of skills (SoS) necessary to hold by operators to safe operation of the UAV. The author will examine two standpoints evaluating their privileges and bottlenecks, or, if there is any, the threat. New idea will be formulated by the author to combine advantages of those two approaches providing a new set of criteria for training system beyond present minimums.

Published: July 2016

Abstract
In the past decades, the exponential evolution of data collection for macroeconomic databases in digital format caused a huge increase in their volume. As a consequence, the automatic organization and the classification of macroeconomic data show a significant practical value. Various techniques for categorizing data are used to classify numerous macroeconomic data according to the classes they belong to. Since the manual construction of some of the classifiers is difficult and time consuming, are preferred classifiers that learn from action examples, a process which forms the supervised classification type. A variant of solving the problem of data classification is the one of using the kernel type methods. These methods represent a class of algorithms used in the automatic analysis and classification of information. Most algorithms of this section focus on solving convex optimization problems and calculating their own values. They are efficient in terms of computation time and are very stable statistically. Shaw-Taylor, J. and Cristianini, N. have demonstrated that this type of approach to data classification is robust and efficient in terms of detection of existing stable patterns in a finite array of data. Thus, in a modular manner data will be incorporated into a space where it can cause certain linear relationship.

Published: July 2016

Abstract
We use from in distribution of the equations for a non viscous, incompressible liquid. Using the Dirac filtering property some integral equations were obtained, giving the liquid velocity and pressure fields due to the bubble’s implosion. The difficulties derive from the fact that the system of differential equations with partial derivates is non-linear and the distribution in the spherical coordinates depends on several parameters. The most important criterion, decisive in the cavitation process, is the one in which the vaporization pressure intervenes pv.

Authors: Calcan Gheorghe 
Published: July 2016

Abstract
Our work aims to present the first debates on the topic of building pipelines for the transport of Romanian oil products. The debut consisted in the report that Anghel Saligny made in 1899. The pipeline system he proposed should have started in the centre of the oil region, i.e. from Băicoi, followed the trail railway Ploieşti, Buzău, Făurei, Feteşti, Cernavodă and reached the sea port of Constanţa. In 1907, engineer L. C. Erbiceanu joined the enterprise. The law was passed by the parliament in 1912. Works began the following year but they were interrupted because of the outburst of the First World War. After a partial use during the war, oil pipelines were completed in 1919.

Published: July 2016

Abstract
The formation of CO2 emissions is largely dependent on the carbon content of the fuel used in diesel engines and on the fuel consumption. The mixture of biodiesel in fossil fuels is in line with most of the research presented in the specialty literature, a method of reducing CO2 emissions from diesel engines. Due to these controversies on the obtained results, the research of the biodiesel effects blended with fossil fuels is still a matter of study. Therefore, a laboratory study has been conducted on a naturally aspirated 4-stroke diesel engine, using different mixtures (10, 15, 20, 25, 30, 40 and 50%) of diesel with biodiesel produced from oil rape. The results of the study revealed the fact that CO2 emissions of the blends used are lower than the same emissions produced when powering the engine with diesel fuel. Furthermore, of all blends used in the study, the 15% biodiesel mixture in diesel fuel was marked by a major decrease of CO2 emissions and of specific fuel consumption.

Published: July 2016

Abstract
Nowadays the global climate changes have determined the international bodies to take measures in order to reduce emissions that contribute to the greenhouse effect. The main component of the exhausting gases produced by diesel engines is the CO2 emissions, considered responsible for the greenhouse effect appearance. The CO2 occurrence is largely dependent on the fuel carbon content as used in the diesel engines and further on the fuel consumption. In this context, it is worthwhile considering the maritime transportation activities taking place since 2011 when IMO took steps to reduce the emissions of CO2 from the exhaust gases of marine diesel engines on ships, enforcing their energy efficiency standards. This paper presents a summary of the main methods for determining the CO2 masses from the exhaust gases of marine diesel engines. These computation methods highlight usage opportunities from the sustainable management principles point of view, promoting the concept of energy efficiency onboard the ships. The undertaken researches open new perspectives in regulation framework, offering new tools for GHG ship emissions’ monitoring and evidence.

Published: July 2016

Abstract
In case of CBRN incidents, the individual decontamination is an extremely urgent measure, for the rescue of personnel from all categories of military forces or from specialized intervention teams, as well as the civilian population unprotected or with minimal protection. Any delay has a significant impact on the fulfillment of combat missions, volume of losses and success of recovery. In this context, it must be considered the possibility that your own troops operate in areas with CBRN risk. The activities with top priority are those relating to the individual protection and immediate decontamination of the personnel, within a very short time, guaranteeing the chances of survival. The paper presents the research results of a multidisciplinary team in the decontamination of chemical, biological and radiological domain for achieving a new individual kit for immediate decontamination, according with the NATO required standards. In the paper the performance and technical-tactical features of the product are iterated, as well as the aspects related to the testing and evaluation of the product development.

Authors: Lăzăroaie Claudiu , Zecheru Teodora , Său Ciprian , Cherecheş Tudor 
Published: July 2016

Abstract
Many CBRN agents are very difficult to detect and identify, due to the fact that most technologies, equipment and materials used for their obtainment have also commercial applications. One possibility to counteract such threats, both for military and civilians, is to use systems of collective protection (COLPRO), which must be manufactured from materials that can withstand not only the action of CBRN agents, but, as much as possible, toxic industrial materials (TIMs). The computational fluid dynamics (CFD) study of the atmosphere in the neighbourhood of the COLPRO tent and the air flow dynamics inside the tent give all the necessary data regarding the effect of air circulation on the entire COLPRO system. Based on this study, a favourable orientation of the COLPRO tent may be established relatively to the strategic position of the troops or the civilian groups, versus statistical wind speed, direction and charge.

Published: July 2016

Abstract
A paper deals with basic theoretical approaches for conductometry employment and its possibilities within testing chemical resistance of barrier materials. A classical conductometry is one from the oldest electro-analytical methods which deals with a measurement of conductivity of solution in water or even another solvent with high relative permittivity when comes to dissociation of an electrolyte on ions. Within employment of conductometric test for evaluation of chemical resistance of barrier materials used in anti-gas protection of the Czech Armed Forces Chemical Corps specialists based theoretical principles have been used. Their application, however, have reached a certain degree of rationalization such as the employment of special carbon electrodes, ensuring temperature compensation within performing long measurements and ensuring mixture of the electrolyte.

Authors: Toma Alecu , Pricop Mihail , Katona Cosmin 
Published: July 2016

Abstract
The experiments have determined that, even close to the detonating underwater charge, the gas bubble and shock wave are sufficiently separated to produce individual effects on plane structures. These results allow evaluating the shock wave parameters and the effects of these two phenomena to be studied separately. This paper focuses on the numerical modeling of the underwater gas bubble effect on submerged plate. We consider a plane structure made from ideal rigid-plastic material. An interaction between underwater explosion and plate will be analytically studied to obtain the equation governing the fluid force per unit length of the structure and the fluid – plane structure interaction equation. The time variation of the gas bubble radius and the explosion magnitude is graphically shown. The interaction between underwater explosion and a submerged flat structure will be simulated.
Analysis of the Possibility of Applying the Maintenance System based on Reliability by Comparative Appreciation of the Braking Installation
Authors: Virca Ioan , Căruţaşu Vasile 
Published: July 2016

Abstract
Analysing the current maintenance system, one can obviously notice a disadvantage to be found in all the cases in which the maintenance activities prove useless, not resulting in finding the flaws or the conditions leading to them, the verified equipment being declared as functioning well. Thus, it becomes indispensable that a rapid and efficient strategy should be implemented for the diagnosis of the component parts of the vehicles, the maintenance based on reliability respectively, which constantly monitors the evolution of parameters so that the permanent state of the vehicle is made known, as well as the necessary maintenance activities. As such, the maintenance based on reliability promotes an efficient policy of the maintenance activities throughout the period of using the vehicle, all the expenses being offset by reducing the maintenance costs through the decrease of the immobilisation time and the number of repair operations. The paper deals with a new approach of the aspects related to the maintenance system of vehicles, relying on mathematical statistics which allows for modelling the strategies likely to be applied within the system. The results of a mathematical approach should not be neglected since the future strategies of managing the maintenance processes of the technical systems cannot be based on simple empirical reasoning, which has most often proved costly.
Bias, its minimization or circumvention to simplify internal quality assurance
Authors: Haeckel Rainer , Gurr Eberhard , Hoff Torsten , on behalf of the working group Guide Limits of the German So  
Published: July 2016

Abstract
Several concepts of analytical bias and remedies to minimize bias have been suggested with the ultimate goal to disregard it. Short-term bias (within one control cycle) should be treated as a random error if it is less than the permissible limits. Long-term bias should be eliminated if it is known or circumvented by estimating intra-laboratory reference limits (RLs). Consequently, analytical uncertainty could be reduced to permissible imprecision. Then, models combining imprecision and bias would become irrelevant, and the numerical value of total analytical error would become identical with imprecision. The purpose of the present report is to simplify quality assurance schemes considerably by disregarding bias either by estimating RLs or by verifying the applied reference limits (checking the transferability) as requested by ISO and CLSI.
