I have read the paper "SinghProduction of hydrocarbon liquid by thermal pyrolysis of paper cup waste". The paper cup waste was pyrolysed in a stainless steel semibatch reactor at a temperature range of 325°C to 425°C and at a heating rate of 20°C min−1 with an aim to study the physical and chemical characteristics of the obtained hydrocarbon liquid and to determine its feasibility as a commercial fuel. The maximum liquid yield was 52% at 400°C. The functional groups present in the liquid are aldehydes, ketones, carboxylic acids, esters, alkenes, and alkanes. It was found that the pyrolytic liquid contains around 18 types of compounds having carbon chain length in the range of C6–C20. The obtained liquid can be used as valuable chemicals feedstock.

I have read the paper: " Gas flaring in industry: an overview". Gas flaring is a combustion device to burn associated, unwanted or excess gases and liquids released during normal or unplanned over-pressuring operation in many industrial processes, such as oil-gas extraction, refineries, chemical plants, coal industry and landfills. Gas flaring is a significant source of greenhouse gases emissions. It also generates noise, heat and provided large areas uninhabitable. The World Bank reports that between 150 to 170 billion m3 of gases are flared or vented annually, an amount value about $ 30.6 billion, equivalent to one-quarter of the United States’ gas consumption or 30 % of the European Union’s gas consumption annually. Thus, a reduction or recover of gas flaring is a crucial issue. Therefore, there is a pressing need to measure flared gas by known its composition, distribution and volume, additionally, applied the suitable flare gas recovery system or disposal. This paper provides an overview of the gas flaring in industry and its composition, and its relevant environmental impacts. It also describes the flaring measurement techniques and the reduction of the flare gas by studying the different methods of flare gas recovery systems.

I have read the paper: "Developing Firing Table Software for Artillery Projectiles using Iterative Search and 6-DOF Trajectory Model". This paper presents the development of the firing table software for computing firing solutions for an artillery projectile. Unlike traditional tabular firing tables, in which the firing solution is determined by interpolating standard condition data then applying correction factors, the iterative search approach employed in this study uses a trajectory model to predict the point of impact in the non-standard conditions and uses search algorithms to converge to the firing solution. The concept and method used in the firing table software are explained and applied to the 155-mm HE M107 projectile. The demonstration program was tested with test cases in non-standard conditions. The results are presented and discussed.

I have read the paper: " Potential of pyrolysis processes in the waste management sector ". The fundamentals of pyrolysis, its latest developments, the different conditions of the process and its residues are of great importance in evaluating the applicabilityof the pyrolysis process within the waste management sector and in waste treatment. In particular the types of residue and their further use or treatment is of extreme interest as they could become the source of secondary raw materials or be used for energy generation in waste treatments. The main area of focus of this paper is the investigation of the link between the pyrolysis conditions, the chemical and mineralogical composition of their products and the benefits of pyrolysis in the waste management sector. More specifically the paper covers the fast, intermediate and slow pyrolysis of organic waste and mixtures of inorganic and organic waste from households. The influence of catalysts during fast pyrolysis on the product yield and composition is not being considered in this review.

I have read the paper “Operational combat-based artillery firing accuracy data analysis.” In the test and evaluation of operation, the test benefits may be greatly reduced because no useful conclusions may be obtained from test data due to missing or incompleteness of test information records. Based on the characteristics of gun firing and by separating firing errors, this paper proposes an idea using for analyzing firing accuracy in case of incomplete test data records, establishes a method for analyzing chi-square distribution-based firing accuracy data, and conducts test data analysis on test data of a certain type of weapon. The effectiveness of this method is proven by analysis results which have offered effective method for conducting test data analysis.

I have read the paper “Fundamental Requirements for the Automated Fire Control System for Field Artillery.” This paper in introduction defines concept of automated fire control system for artillery support (ASRPP-DEL) and further divides into chapters according to the requirements that the system had to fulfil, including standardization agreements. First are mentioned general system requirements then all necessary data, which we put into the system. Other chapters deal with supporting commander ́s action, tactical and technical fire control, calculating firing data and the already mentioned standardization. Conclusion contains a summary of the requirements and recommendations for ASRPP-DEL arising from this work.

I have read the paper “Aircraft Gun Reliability Modelling.” This article deals with modelling and analysis of reliability of complex systems that use oneshot items during its operation. It includes analyses of an impact of reliability of used one-shot items on resulting level of reliability of the system as a whole. Practical application of theoretical knowledge is demonstrated on an example of a model of reliability of PL-20 aircraft gun that was used for optimization of the gun’s design during its development and designing. A probability of accomplishment of a mission is the most important measure for assessment of reliability of a gun as a whole. From the description of the gun is evident that probability of accomplishment of a mission depends both on a reliability of used rounds and pyrotechnic cartridges. A proposed model and solution enable to analyze a responsiveness of the whole system.

I have read the paper “Biomass Fuel and Combustion Conditions Selection in a Fixed Bed Combustor.” The biomass market has experienced an increase in development, leading to research and development efforts that are focused on determining optimal biofuel combustion conditions. Biomass combustion is a complex process that involves divergent parameters and thus requires the use of advanced analysis methods. This study proposes combining grey relational analysis (GRA) and error propagation theory (EPT) to select a biofuel and its optimal combustion conditions. This research will study three biofuels that are currently used in a region of South Europe (Spain), and the most important variables that affect combustion are the ignition front propagation speed and the highest temperature that is reached at the fixed bed combustor. The results demonstrate that a combination of both theories for the analysis of solid-state thermochemical phenomena enables a fast and simple way of choosing the best configuration for each fuel.

I have read the paper “The Influence of Additives on the Temperature, Heat Transfer, Wear, Fatigue Life, and Self Ignition Characteristics of a 155 mm Gun.” The temperature and heat transfer per round was measured at the bore surface of a 155 mm AS90 extended range ordnance. The ammunition was fired with and without wearreducing additive and the measurements were made using an eroding-type surface thermocouple having response time of about a microsecond. The heat transfer was computed from the measured temperature-time curves. It was found that the wear-reducing additive gradually reduced the surface temperature fluctuation from about 950°C to about 600°C, and reduced heat transfer per round from about 950 kJ/m2 to about 600 kJ/m2 , over a period of 50 rounds. From these measurements an assessment was made of the wear rate, the number of rounds to cook-off, and the increase in barrel fatigue life. Similar experiments on 30 mm RARDEN and 40 mm Bofors guns, using different additives, resulted in comparable reductions in bore temperature and heat transfer, but the mechanism for these reductions was different and it is still not clear exactly how these additives reduce barrel temperature and heat transfer.
