Of course, as a consequence, the wars and methods have changed a lot. In this article, I analyze and systematize the structures used to protect the personnel previously employed in the Hungarian Defense Forces in order to draw conclusions on their further applicability and possibilities for modernization.</abstract>

Concurrently, the logistic system of the military units during peacetime tracks the supply of material assets for emergency situations, crisis, mobilization and war. Achieving logistic support for military units during peacetime depends on a number of principles that underpin the provision of high-quality logistic support necessary for the fulfillment of the basic mission and the fundamental objectives of each military structure.</abstract>

The Military Units’ Logistic Support Principles

The research methods used was the experiment method, using two groups: the first group was the control group and the second the experiment group. The experiment consisted in testing the students at: 50 m speed running, 800 m resistance running, push-ups, and specific testing like: 50 m swimming with obstacles, 8 km run in varied terrain.The results of our investigation showed that calculation of the statistical significance of the differences between the averages of the two samples showed significant values at p>0.05, n-1, at the following parameters: running 800 m (t = 2.71> 2.13 - p = 0.05); push-ups (t = 3.01> 2.95 - p = 0.05); freestyle swimming 50m (t = 2.81> 2.13 - p = 0.05).</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">This approach examines the comparative relationship between persuasion at micro and macro-social level, under the framework of the comparative analysis method. In this sense, after identifying and presenting the concept of persuasion, the similarity of interpretation and persuasion techniques are emphasized. The study first addresses the epistemological and methodological aspect of the social connotations of persuasion. It has as main objectives to ensure the interpretation of the concept, to identify the strategies, to describe the mechanisms by which the persuasion in the public space is reconstructed and to discover the methods of resistance to this type of communication.The usefulness of studying this type of communication results from the effects it has on the individual and its various inter-human relationships in the macro-social space.</abstract>

Persuasion Connotations at Macro-Social Level

<abstract xmlns="http://www.w3.org/1999/xhtml">It has long been considered that the environment can withstand all the pressure exerted by human activities on it: extensive agriculture, pesticide use, strong industrialization, noxious gas emissions into the atmosphere, toxic product discharge into lakes, rivers, seas and oceans, massive deforestation to obtain new areas for housing or agriculture. The result was environmental and soil degradation, increased water and/or air pollution, climate change, biodiversity loss, the disappearance of plant and/or animal species, the depletion of some natural resources. These environmental changes have begun to be studied by specialists in the field, who have raised a flag to irreversible environmental changes.The concept of “sustainable development” arose at a time when environmental issues were at the heart of political debate: sustainable development is seen as a complex and difficult issue to solve because there is a diversity of interests of different states. International agreements and cooperation from the point of view of globalization and economic harmonization have also had as their object the issues of sustainable development, by launching the attempt to reconcile the economy with the environment.</abstract>

Premises of Sustainable Development Concept Occurence

<abstract xmlns="http://www.w3.org/1999/xhtml">Enormously studied by specialists, the leadership of organizations is a primordial issue because the leader’s style conditions the efficiency of any social organization. This is one of the reasons why the current scientific concerns focus on studying the ways of improving leadership and the choice of leaders who have the skills and capabilities to successfully perform such functions. This paper deals with the characteristics of the military organization and the complex environment in which it operates, imposing major demands on the military leaders, who must develop certain skills and abilities in order to cope with the wide range of challenges they are confronted with on the modern battlefield. It also points to the features of charismatic leaders, drawing the attention to the relationship between subordinates and leaders, a relationship that is based on an emotional, spiritual, even non-rational bond between leaders and followers.</abstract>

The Issue of Leadership Styles in the Military Organization

<abstract xmlns="http://www.w3.org/1999/xhtml">A multiple rank modulation (MRM) scheme is proposed that provides better error performance, enhances the data rate and reduces the system demodulation complexity. Multiple input multiple output (MIMO) scheme is a technique that uses several antennas at the transmitter and receiver to minimize error and optimize data speed. MRM is a novel technique that borrows from spatial modulation-MIMO (SM-MIMO) scheme. The basic idea of this scheme involves the transmitter receiving a group of bits and subdividing them into two blocks; rank index block and signal modulation block. The rank index bit block is used to select the rank to be activated and the rank selected contains at least one active transmit antenna (TA). The signal modulation bit block is encoded in a given modulation scheme for transmission. It is then transmitted through the activated rank that contains at least one active TA. The transmitted encoded signal modulation bit block is received through the receive antenna and a receiver. The receiver estimates a rank index and the transmitted symbol from the signal received. The signal modulation bit block is finally decoded. This paper addresses the performance of MRM scheme based on error performance to run cellular fifth generation (5G). We perform and present simulation results of MIMO systems employing MRM scheme to generate bit error rate (BER) of this system.</abstract>

Performance of Multiple Rank Modulation Based on SM-MIMO

<abstract xmlns="http://www.w3.org/1999/xhtml">Frequency hopping is used in different communications systems for its robustness by providing frequency diversity against jamming and interfering signals. Successful detection and demodulation of a frequency hopping signal is dependent on proper tuning to transmit frequency and time synchronization of the burst. The sequence of hop frequencies is generally determined by a Pseudo-Noise (PN) sequence and time synchronization is achieved using synchronization preambles in the transmit burst. Successful acquisition of the hop frequency sequence could be achieved when at least a single burst’s data is successfully decoded at the receiver. This paper studies the serial search code acquisition which is the first step of synchronization for frequency hopping spread spectrum (FHSS) system over Rician fading channel. Simulation results show the effect of fading channel on the code acquisition.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">This paper implores the parallelization of Fast Fourier Transform (FFT) algorithms and evaluates the resultant parallelized source codes. The FFT algorithm is considered to be among the most important algorithms in the digital era. There are various FFT algorithms but just a few are considered in this paper. The Cooley-Tukey FFT is the most widely known and used. With no exception, in this paper, the radix-2 Decimation in Time (DIT) and Decimation in Frequency (DIF) are studied and implemented. Another important FFT algorithm that is the Goertzel is also considered in this paper.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">This paper presents a methodology to validate a virtual test procedure for vehicle gradeability performance. It is a test dedicated to both the civilian and military off-road vehicles, an 8 x 8 Armoured Personnel Carrier being selected for the purpose of the paper. TruckSim is the software used to implement the vehicle math model and the test procedure. The simulation results are compared with the experimental results for a 60 % gradient. The vehicle speed and the engine speed graphics, the statistical analyze, and the comparison between the simulation test animation and the experimental test movie are the methods applied to validate the virtual longitudinal slope test procedure.</abstract>
