Formulating the dynamics equations of a mechanical system following a multibody dynamics approach often leads to a set of highly nonlinear differential-algebraic equations (DAEs). While this form of the equations of motion is suitable for a wide range of practical applications, in some cases it is necessary to have access to the linearized system dynamics. This is the case when stability and modal analyses are to be carried out; the definition of plant and system models for certain control algorithms and state estimators also requires a linear expression of the dynamics. A number of methods for the linearization of multibody dynamics can be found in the literature. They differ in both the approach that they follow to handle the equations of motion and the way in which they deliver their results, which in turn are determined by the selection of the generalized coordinates used to describe the mechanical system. This selection is closely related to the way in which the kinematic constraints of the system are treated. Three major approaches can be distinguished and used to categorize most of the linearization methods published so far. In this work, we demonstrate the properties of each approach in the linearization of systems in static equilibrium, illustrating them with the study of two representative examples.

Subject. This article discusses the issues of reflection of information on settlements with equity construction investors both on off-balance and balance sheet accounts of the developer. Objectives. The article aims to determine the extent of the transition to project financing of housing construction using escrow accounts, explore options for accounting for incoming funds of equity construction investors, and develop a methodology that helps avoid tampering with the balance sheet total of developers. Methods. For the study, we used induction, deduction, analysis, synthesis, and the calculation and graphic, monographic, and accounting and analytical methods. Results. In some cases, the findings have revealed significant discrepancies the way funds available to escrow accounts get accounted for. An analysis of the causes of these deviations confirms the need to develop an off-balance sheet accounting methodology. Conclusions and Relevance. The updated methodology is structured in such a way that the investors' funds are accounted by the developer in one account, another account is used for settlements with the equity construction investors, and the funds placed by the bank on the escrow accounts are reflected in the off-balance sheet of the developer, without misrepresenting the balance sheet total. The results can be used in the theory and practice of construction companies in the process of accounting and reporting by business entities of various forms of ownership, as well as for further scientific developments and practical applications.

The Individual

The tandem catalysis of ring-closing metathesis/atom transfer radical reactions was investigated with the homobimetallic ruthenium–indenylidene complex [(p-cymene)Ru(μ-Cl)3RuCl(3-phenyl-1-indenylidene)(PCy3)] (1) to generate active species in situ. The two catalytic processes were first carried out independently in a case study before the whole sequence was optimized and applied to the synthesis of several polyhalogenated bicyclic γ-lactams and lactones from α,ω-diene substrates bearing trihaloacetamide or trichloroacetate functionalities. The individual steps were carefully monitored by 1H and 31P NMR spectroscopies in order to understand the intimate details of the catalytic cycles. Polyhalogenated substrates and the ethylene released upon metathesis induced the clean transformation of catalyst precursor 1 into the Ru(II)–Ru(III) mixed-valence compound [(p-cymene)Ru(μ-Cl)3RuCl2(PCy3)], which was found to be an efficient promoter for atom transfer radical reactions under the adopted experimental conditions.
