    Big Data is becoming one of the most important technology trends. It presents a potential that is radically changing the way organizations use their information to be closer to customers by organizing in a way that benefits from the customer experience and transforms their business models.
    Although Big Data is an ever-climbing trend in terms of industry, its meaning is still hidden by many conceptual ambiguities. The term is used to describe a wide range of concepts: from technological ability to storage, aggregation, data processing and finally their generation. In this paper the focus is at Big Data, because they are the technology of the future and in one way or another, they are affecting every field of industry. Furthermore, companies are increasingly trusting the possibility of using data as a valuable business asset to benefit and bring a competitive advantage compared to other companies. In the paper is presented also a SWOT Analysis that is conducted about Big Data information showing the strengths, weaknesses, opportunities, and risks that they carry. Also are presented the challenges of Big Data Technologies for the future. At the end of the paper, there are conclusions and recommendations about the topic.

    Language learning and technology has now become an interesting field of inquiry for many research scholars and professionals in the field of second language acquisition. Advances in information technology have affected second language teaching and learn ing as well. A plethora of research on the development of second language skills has surged especially in the last two decades. A number of studies employing various research designs and methodological approaches have provided some evidence on the effectiveness of technology on second language learning and teaching. However, much of research has shown mixed findings and inconclusive results. Hence, research community is encouraging further studies on the pursuit of finding out for whom and under what condition s is technology rather effective in language learning and teaching. This paper presents a brief review of previous studies and some preliminary research on the effects of technology, i.e. multimedia annotations/glossing on second language vocabulary learning. This paper draws on Mayer’s Cognitive Theory of Multimedia Learning (2009) and examines the impact of multimedia annotations on second language vocabulary learning. Prelimin ary research shows that certain multimedia annotation modes yield positive evidence on enhancing second language reading comprehension and vocabulary learning.

    Delay Tolerant Networks (DTNs) enable communication in networks with low density, low connectivity and high mobility. DTNs are suitable in areas where an infrastructure does not exist. DTNs use store-carry-forward approach. The performance of such networks is strongly connected with nodes mobility. Vehicles can be part of DTNs. In this paper we will investigate the role of buffer size and vehicles of transportation system as message forwarders in a DTN in Tirana city. The performance metrics for evaluation are delivery probability, average latency and overhead ratio. The simulation results show that transportation system can be used as a backbone for DTNs in urban areas.

    Industry 4.0 represents the newest generation of industry development. Every day the various demands in industry are getting more and more demanding. The demand for shorter production and delivery time, more efficient and automated processes has led us to the Industry 4.0. It is necessary to include and integrate the latest developments based on digital technologies as well as the interoperability process across them. The goals is to enable companies to transmit information in real time in terms of performance and behaviour. Industry 4.0 can be applied to any branch of industry. Agricultural industry is no exception. As far as agricultural machinery is concerned, it is a very important part of agricultural industry. Agricultural machinery incorporates electronic controls and it is a part of digital age, enhancing their current performance. In addition to the electronics, using sensors and drones, supports the data collection of several agriculture key aspects, such as weather, animals and crops behaviour, geographical spatialization, etc. The main tasks are how to apply the right methods and methodologies in order to support a better supply chain decision-making process, how to automate the process and how can Industry 4.0 help a person, who is in agricultural industry, in order to make effective decisions based on objective data.

    Determining the sustainability of agricultural production are agro-technical activities, as the main units in any technology. A study has been carried out to evaluate the impact of crop treatment systems, mineral fertilization and integrated weed control on soil and climatic conditions in the Sofia region.
    It has been found that less intensive weeding with annual and perennial weeds is observed when using a more intensive treatment system compared to the reduced treatment option. The number of weeds per unit area is increasing in the non-fertilizing variants, but their mass is lower than the fertilizers. Deeper soil tillage contributes to maintaining the values of the physical parameters (humidity, bulk density and soil hardness) in a more favorable range. Fertilization has the most significant effect on yields during the three years of the experiment.

    The structural-logical model of training of future specialists in agroengineering for innovative project activity has been developed on the basis of a systematic comprehensive study of the theoretical course of agricultural machines, the deepening of the students’ scientific work on the development of supporting and moving elements of machine-tractor units, including pneumatic tires. The samples of individual fragments from the algorithm and the method of calculation of wheels used in the educational process are provided and the general and professional competencies of the agroengineer are created, especially during the implementation of future specialists in agroindustrial production of higher education courses in the course of master’s and master’s studies. It is noted that the training of agroengineers for innovative project activities is carried out in accordance with the Law of Ukraine “On Higher Education” and the standards of higher education of Ukraine. The influence of interdisciplinarity in the system of cross-cutting project preparation on the readiness for implementation of production practical tasks is investigated. It is confirmed that the support-run elements of aggregates in the conditions of complex terrain contributes to the development of erosion processes and negatively affect the soil fertility. Any tire better satisfies the condition of permissible wheel pressure on the soil if the air pressure in the tire is low. Improving the technological process of manufacturing tires for agricultural purposes allows them to ensure their quality, reliability and operational safety.

    The results of development of the technology for manufacturing samples of insulators made of alumina ceramic with an aluminum oxide content of up to 95% are presented. The maximum tensile strength of the produced insulators has been investigated. The structures of the chip of the ceramic insulator surface have been obtained. It is shown that a change in the aluminum oxide content by 8-10% leads to an increase in the strength properties of the product by 1.5 times. The developed technology can be used to produce high-strength dielectric products, for example, antenna rod insulators, applied in the field of electrical engineering, radio engineering and other industries.

    Studying the right field has great importance in human life and perspective. Rather than affecting the greatest employer’s ability, some studies see higher education as one of the leading factors that directly affects the style of life that we do. Therefore, today’s demands have increased significantly for skilled people, and prepared in complex areas, and a consolidation between market demands and university curricula is needed. This paper examines Data mining techniques which are used in order to create an automated model which makes comparisons between market demands and university curricula. We also present how proposed model is able to give recommendations, based on the comparison between market demands and university curricula.
