Cyber-physical systems are structures that are controlled and monitored by computer-based algorithms consisting of physical components. The energy industry is becoming a large and complex cyber physical system with the industrial revolution. These developments in the energy sector have a positive effect on Industry 4.0. Developments in the fields of production, transmission and distribution, retail sales, trade and consumption from the elements of the energy sector are increasing day by day via sensor-based communicable autonomous systems. U.N. Industrial Revolution in its report in 2017 elaborate the relevancy between the Sustainable Development Goals no. 7 and 9 about sustainable energy and inclusive industry development that Industry 4.0 and sustainable energy transition share crucial concerns that can be interconnected to pursue a sustainable energy transition. Sustainable energy is defined to have two main components: energy efficiency and renewable energy. UNIDO’s initial hypothesis tells that a comprehensive shift in manufacturing may change the behavior in energy consumption, including energy efficiency and renewable energy usage. Circulating fluidized bed (CFB) technology is one of the important factors contributing to the above mentioned concept of sustainable energy.

Mathematical modeling is the key parameter in designing new devices. Renewable energy technologies are getting higher importance in the near future. Mathematical modeling of circulating fluidized bed (CFB) biomass combustion could improve both their design and operation, reduce any associated problems and facilitate the implantation of this technology. A good understanding of the combustion and pollutant generating processes in the gasifier can greatly avoid costly upsets. Presently, there is a focus on developing models of CFB for burning biomass and waste material. The objectives of these models are to be able to predict the behavior with respect to the combustion efficiency, fouling problems and pollutant emissions performance of different fuels or mixtures in commercial CFBs. In this study, importance of mathematical modeling in designing CFB biomass gasifiers is investigated in view of innovative solutions.

EVOLUTION OF RESEARCH AND DEVELOPMENT CENTER FOR REGIONAL DEVELOPMENT: CASE STUDY OF MAKU R&D CENTER
The role of universities in R&D activities is a subject which needs to be reevaluated and thought over in terms of their contribution to the related industries, their vicinities and research parks. The mere reason of the existence of universities is to push the boundaries of the existing knowledge to achieve better and more reliable results in any given field. Although the ideal is having universities which are able to adapt really quickly to changes, often the reality is not so. The change is mostly slow and not swift enough to keep up with the recent developments in many fields such as the economic changes. These changes in the manner of universities require long periods of time. This is one of the reasons why universities should be quick to respond to regional needs and shifts to help pursue more attainable and resilient ecosystems. The main objective of this article is to analyze the role of research and development unit Mehmet Akif Ersoy University R&D services. It aims to support co-evolution of local municipal and industrial enterprises to increase the competitiveness of the region.
EFFECT OF ALLOYING ELEMENTS ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF NiAl-Cr(Mo) EUTECTIC ALLOY
Microstructure and mechanical properties of NiAl-Cr(Mo) eutectic alloy and the effect of 0.1Fe,1Nb,4Ti additions are investigated at room temperature (RT) and high temperature (1000°C). The alloys are prepared by arc melting method and then homogenized at 1300°C in Ar atmosphere for 24 h. In addition to the room temperature and high temperature compression tests and X-ray diffraction measurements, hardness measurements and microscopic analyses at room temperature are performed. NiAl-Cr(Mo) alloy exhibit fine cellular eutectic structure with coarse eutectic at interdendiric regions. However, the Nb and Ti addition reduced the formation of eutectic structure. Cr2Nb-type Laves and Ni2AlTi-type Heusler phases are observed in the XRD patterns of the Nb and Ti containing alloys respectively. Addition of Fe does not have important effect on the room and high temperature yield strength of the alloy, while the Nb and Ti increase the yield strength of the alloys at both temperatures.
DOMINANT TECHNOLOGIES IN “INDUSTRY 4.0”
Solar collectors are one of the most promising renewable technologies for energizing future systems. Solar collectors are used for a variety of heating systems such as domestic hot water systems and industrial application. Increasing the collector efficiency is an important factor in terms of unit cost. In this study is to increase efficiencies of flat plate solar collectors. For this purpose, various apparatus was place into collector tubes which increase the heat transfer between plate and fluid, thus it developed a new collector. In addition, a new collector hot water tank was designed. The changes in warehouse and collector were compared with the classical systems and the change in the usage water was calculated.
