Regulation of diesel by variation of physical - chemical and motor properties of fuel
Abstract
There are examined a problem of diesel regulation by variation of physical-chemical and motor properties of fuel during the working process of engine. The composition of fuel is changed by addition some alternative fuels and other addтitives to base diesel fuel. The method is realized by using of fuel system with regulation of initial fuel pressure.

Developmnet of the automobile explosion engine performance with direct injection of gasoline
Abstract
Here are analyzed the problem questions which are connected with perspective working out of domestic automobile petrol engines of new generation with internal carburetion which stimulates necessity to search the means and the new technical decisions which can be suitable for domestic engine engineering. The method of developing automobile explosion engine performance of the given type has been suggested as an alternative variant, which is based on the use of hydrogen as a chemical reagent.

On application and analysis of helicoidal shells in architecture and civil engineering
Abstract
There is the review article of application and calculation of helicoidal shells in architecture and civil engineering. Helicoidal shells are used as ramps, winding staircases, screws, elements of bore machines and so on. Different numerical methods are widely used nowadays, but analytic methods need research. There is also information about author's computer programs written in MathCad for analysis of shallow right and open helicoids. The method of Rekach was corrected by the author and led to numerical results. Analytical method of S.N. Krivoshapko was simplified by author due to the application of Bernoulli numbers in the process of integration of equations. The author suggests using mentioned programs for rough analyses of helicoids instead of expensive program complexes based on numerical methods.

Analysis of initial stresses in a sectorial-lattice dome during installation as an assembled structure in comparison with a star-lattice dome
Abstract
The article presents the results of a computer-based research on the nature of the initial stresses in the bars of one-layer sectorial-lattice dome that arise from the deformation of the framework during its erection as a wholly assembled structure. Comparative analysis of the possible initial internal forces in the bars has been performed for various cases of the initial support, as well as for different types of probabilistic combination of tolerances. Obtained results are compared with the results of a similar research performed earlier for the star-lattice dome.

The network operator method in a problem of synthesis for control system of dynamic object with random initial values
Abstract
A general problem synthesis of control system for object with random initial values is considered. To solve the problem it’s proposed to use the network operator method. An example of decision of a control system synthesis problem for an aircraft on a stage of descent is presented.

Effect of water-permeable foundation layer thickness on filtration flow data with approximate e quality of dam body and its foundation filtration factors
Abstract
Hydraulic (approximate) method is used to analyze filtration flow data of earth dams emplaced on water-permeable foundation of different thickness with approximate equality of dam body and its foundation filtration factors. Redetermination necessity of filtration flow data was discovered as a result of comparative analysis of water-permeable foundation layer thickness effect on filtration flow data.

Cyclic surfaces with directrix meridians of the base surface of revolution
Abstract
The questions of forming of the cyclic surfaces with plane of parallelism made by the circle of the changed radius moving on two meridians of the base surface of revolution are concern. There received the vector equation of the surfaces. It is shown that on the base of those surfaces there may be constructed varies shells of umbrella type. There shown drawings of some cyclic surfaces and surfaces of umbrella type with different base surfaces of revolution.

Modern approaches to designing of many-storeyed housing estates in conditions hot-arid climate (on an example of the UNITED ARAB EMIRATES)
Abstract
In article modern problems of space-planning, constructive solutions of modern perspective multipurpose housing estates in the conditions of a hot arid climate, with emphasis on national features of the United Arab Emirates are considered. MSHE are the complexes which are carrying out a set of functions, uniting in itself the dwelling, expanded typological structure, establishment of service, culture, communication, entertainments, and also offices and trading enterprises. The architectural solution of MSHE is a result of architectural judgment of a number of objective factors: climatic, economic, social conditions, town-planning situation, space-planning structure of a complex, its constructive scheme, techno
