An adequate method for calculating chemical equilibrium in a predominantly gaseous, multi-component reactive mixture was investigated and successfully applied. This method involves the stated equilibrium reaction scheme, including, first, the formation of chemical species, of which concentrations prevail in the mixture, then the formation of gaseous atomic species by dissociation of previous ones, and, finally, the formation of complex chemical species from the atomic species.

Abstract:
The chapter presents express methods for estimating the solar energy potential at a given point on the basis of combining the solar radiation daily profile application method under clear skies and actinometrical data of the NASA electronic base. Such a new approach including the climatological conditions of the region, significantly reduces the calculation time, and improves the accuracy of the decisions with a minimum of initial data. For the speed and convenience of calculations based on the proposed methodology, it was implemented in the form of a computer program. The article also analyzes the influence of spatial orientation on the maximum electricity produced during the month, season and year and it reveals that the use of an optimal inclination angle for the specified periods of time makes it possible to realize the existing solar potential of the region at the same capital expenditures.

Abstract:
In 1998, the National Aeronautics and Space Administration (NASA) launched the Mars Climate Orbiter (MCO) as part of the Mars Surveyor ’98 program. Upon arrival at Mars, MCO was to enter an elliptical orbit around the planet. On the day of orbit insertion, ground control was able to track the spacecraft visually up to the point when it vanished behind the planet. Unfortunately, the spacecraft never reappeared on the other side. It was later discovered that the probe came too close to the planet, and crashed into the Martian surface. The cause? A previously undiscovered mismatch in the use of unit systems for performing certain calculations in parts of the ground station software [43].

Abstract:
. . .Formal methods offer much more to computer science than just “proofs of correctness” for programs and digital circuits. Many of the problems in software and hardware design are due to imprecision, ambiguity, incompleteness, misunderstanding, and just plain mistakes in the statement of top-level requirements, in the description of intermediate designs, or in the specification of components and interfaces. Rushby [1993] . . .Desire for correctness proofs of systems spawned the research area known as “formal methods”. Today’s systems are of sufficient complexity that testing is infeasible, both computationally and financially. As an alternative, formal methods promote mathematical analysis of a system as a means of locating inconsistencies and other design errors. Techniques used can range from writing system descriptions in a formal notation to verification that the designed system satisfies a particular behavioral specification. A good general introduction to formal methods appears in Rushby [1993]. Ideally, using formal methods increases our assurance in and understanding of our designs. Assurance results from proof, while understanding results from the process of producing the proof. Successful use of formal methods therefore requires powerful proof techniques and clear logical notations. The verification research community has paid considerable attention to the former. Current techniques, many of which can be fully automated, handle sufficiently complex systems that formal methods are now being adopted (albeit slowly) in industry. In our drive to provide powerful proof methods, however, we have overlooked the latter requirement. Research has focused on proof without paying sufficient attention to reasoning. Current tools are often criticized as too hard to use, despite their computational power. Most designers, not having been trained as logicians, find the methodologies and notations very unnatural. Industrial sites, starting out with formal methods, must often rely on external verification professionals to help them use these tools effectively (NASA [1995]). Tools that are not supportive of reasoning therefore fail to provide the full benefits of formal methods. We can augment our current methodologies to address this problem, but we first need to understand reasoning and its role in hardware design.
