Potential Opportunities for Development of Mechanical Engineering with The Context of Historical Evolution of This Engineering Branch

Short Communication

Mechanical engineering is not only one of the oldest engineering disciplines but also the broadest one, i.e., with the wide-scope as well as a large number of its branches. This engineering discipline requires a clear understanding of the principles of engineering physics, engineering mathematics, and materials science to design, analyze, manufacture, and maintain mechanical systems such as mechanisms, devices, and machines.
With a view to machines’ development, the progress of mechanical engineering advancement is often directly related to the course of civilization history. Therefore, it can be studied from many perspectives. Our attention often directs to significant particular forms or stages of civilization, which arisen throughout human history. One cannot forget about ancient cultures, both Greco-Roman (in Europe) and Chinese (in Asia), which adopted to a great extent and, then, developed often anonymous technical achievements of the first civilizations of the prehistoric period [1].
The illustrious ancient achievements had been followed by the technical culture of Islam, which not only systematized them but also improved a bit afterward. In the late Middle Ages, these achievements spurred European societies to search for new mechanical devices and, thus, the foundations were laid for the subsequent Renaissance. During the Renaissance and also after it, there was an excellent development of creative and innovative engineering thinking enshrined in treaties on machines, especially in the anthology of Italian, French as well as German technical literature. The Industrial Revolution was the culmination of all previous technological advances and which manifested itself by the transition of production processes from old manual methods to new ones supported by machines.
Mechanical engineering may be treated as a precursor to many branches of engineering, including mechatronics that is an interdisciplinary branch of mechanical engineering and electronic engineering at least, to create controlled hybrid systems, thanks to which machines can be easily automated. Besides, the use of microprocessor-based digital embedded controllers, together with a wide selection of control software algorithms dedicated to these programmable microcontrollers, enables us to build specific pieces of automation equipment based on electric motors, servo-mechanisms, and other electrical systems. Mechatronic structures are the result of the evolution of mechanical objects, bearing in mind the development history of mechanical engineering. According to the conceptual block diagram shown in Fig. 1, the application of digital technologies in mechatronic systems has provided a very different approach to automatic control [2, 3]. Thanks to the use of modern digital computers, more and more often, in the case of advanced control methods, purely mathematic models of systems’ behavior and controllers’ algorithms are abandoned in favor of sophisticated artificial intelligence (AI) techniques with the help of which control systems can learn about their environment and properly modify their behavior in conjunction with control based on knowledge to ensure their optimal performance. For this to be possible, advanced control systems must have sufficient computational capacity to create not only representative mathematical models of the controlled systems but also to modify their own adaptive control actions [4].

Overview of Known Alkaliphilic Bacteria from Bauxite Residue

Abstract Alkaliphilic bacteria usually grow well at pH 9, and the most extremophilic strains can grow up to values as high as pH 12-13. This group of bacteria has the ability to metabolically reduce alkalinity and are tolerant of high concentrations of ions and metals. Interest in extreme alkaliphiles has been shown as they are sources of useful, stable enzymes, and the cells themselves can be used for biotechnological and other applications at high pH values. Many industrial processes produce highly alkaline waste that is contaminated with toxic trace metals/metalloid. Thus, using alkaliphilic microorganisms is considered an attractive alternative method for treating industrial alkaline residues. Bauxite refining is one of the activities that most produces highly alkaline waste. Alumina extraction from bauxite using concentrated sodium hydroxide in the Bayer process generates a slurry and an extremely alkaline (pH of 9 to 13) by-product known as bauxite residue or r

Effect of Annealing Process on Microstructure of SiC-Mg Mixture Powder

Abstract SiC particles with 8wt.% magnesium alloy powders as additives were mixed followed by annealing at 280 and 400 ℃ for 1 and 4 h. The particle size, phase condition, morphology and compositions distribution were analyzed using laser diffraction analyzer, X-ray diffraction (XRD), scanning electron microscopy (SEM). It was found that particles mixed homogeneously before annealing. Annealing processes have a positive effect on the decrease of magnesium alloy particle size. It has almost no effect on magnesium alloy particle size with increasing the annealing duration at 280 ℃. However, the diameter of magnesium particle decreased obviously with increasing the annealing duration at 400 ℃. Magnesium alloy particles annealed at 400 ℃ is smaller than that of the 280 ℃ ones under the same annealing duration. Si component was observed in powder annealed at both temperatures. Grain size of SiC was reduced and microstrain was improved with increase of annealing temperatu

Syngas Compositions, Cold Gas and Carbon Conversion Efficiencies for Different Coal Gasification Processes and all Coal Ranks

  Abstract This Paper presents comparison of syngas compositions, for all coal ranks, as produced from different types of coal gasification processes currently in use, namely entrained flow, fluidized bed, and fixed bed gasifiers. Cold gas and carbon conversion efficiencies were investigated. The syngas composition varies with the applied gasification process. The importance of this research arises from the fact that gasifiers produce the environmentally clean fuel required to run any Integrated Gasification Combined Cycle power system. A procedure was conducted to get estimates for bituminous coal. It is important to have knowledge of the chemical reactions which take place in each gasifier and the raw syngas produced from the specific reaction involved to develop an Integrated Coal Gasification Combined Power Generation plant with CO 2 recovery in order to increase the cycle efficiency and mitigate CO 2 emission and other pollutants. The results indicate that the e
