In this study, a 3D-model of a four-stroke, single-cylinder diesel engine was built using AVL Fire software to evaluate the influence of injector geometry parameters on engine characteristics. The results have shown that, with the injection pressure reaching 3000 (bar), and the turbocharger pressure maintained at 0.15 (MPa), the engine achieves the maximum power and the minimum brake fuel consumption when the angle between the axis of the nozzle hole and the axis of the fuel injection nozzle is 150 degrees.

This paper determines a suitable opening angle of the hydraulic support legs of M46-130 mm self-propelled artillery. It is a combination of M46-130 mm field gun, mounted on KrAZ-255B 6x6 military truck chassis. Based on results of investigating the changes of forces and moments acting on artillery system in static condition when changing the opening angle of hydraulic support legs at critical fire angles, a suitable angle is selected at ψ = 400 and γ = 200 . From that angle, this paper shows a table consists of geometric parameters, forces and moments acting on system.

Concrete is an inherently brittle material with a relatively low tensile strength compared to compressive strength. Reinforcement with randomly distributed short fibres presents an effective approach to the stabilization of the crack and improving the ductility and tensile strength of concrete. A variety of fibre types, including steel, synthetics, and natural fibres, have been applied to concrete. Polypropylene (PP) fibre reinforcement is considered to be an effective method for improving the shrinkage cracking characteristics, toughness, and impact resistance of concrete materials.

This paper deals with break size estimation of loss of coolant accidents (LOCA) using a nonlinear autoregressive with exogenous inputs (NARX) neural network. Previous studies used static approaches, requiring time-integrated parameters and independent firing algorithms.

This paper will propound an antenna covering the range of frequencies from 1.53 GHz to 2.53 GHz that includes 1.575 GHz, 1.8 GHz, 1.9 GHz ,and 2.1 GHz. The developed quasi-Yagi antenna has a simple-low profile and achieves a bandwidth of 48%, a front- to- back ratio of 19 dB, a gain of 6dBi, and an efficiency of better than 78% at 2.1GHz. In this paper, the study on effects of parameters of the antenna is also investigated to achieve optimal model.

The pink coral pigment has been synthesized from silica (quartz sand in Thua Thien Hue province), zirconia and iron (II) sulphate hetahydrate using a mixture of sodium fluoride and potassium cloride as mineralisers to lower the temperature of reaction. By measuring colour parameters (CIE, L* a* b* ) of coloured glaze, using DTA and XRD methods we have studied the influence of mineralisers and firing temperature in pigment synthesized.

As Carlo (2001) comments in a recent review, “research on cross-language transfer has made some progress with regard to the issue of identifying particular skills that appear susceptible to transfer from first- to second-language reading. However, questions remain concerning the specification of the cognitive mechanisms responsible for transfer as well as the developmental parameters that constrain transfer effects.

The universal UDF in this case is called SAS_SCORE. This UDF is slightly different in that it can take a table or result set name as input, and the output is a result set. Call this a table UDF (compared to a scalar UDF like SAS_PUT UDF, which outputs a single value). The input parameter list of the SAS_SCORE UDF varies according to the DBMS and the model being executed. Regardless, the input parameter list of SAS_SCORE can be broken into two sets: the name of the scoring function to be run and the table or result set containing the...

Quirra is a small village located in the south-eastern part of the Italian Sardinia Island (Sardegna), in the centre of the Mediterranean Sea. It is close to the sea shores (Capo San Lorenzo), and surrounded by other small villages like Perdasdefogu and Escalaplano. In that area, it is located the biggest military polygon of Italy and Europe, the "Poligono sperimentale di addestramento interforze del Salto Quirra" (“Salto di Quirra Polygon” and firing range).

The elderly population is seen differently in developing and developed countries. In the former, the age limit for a person to be considered old is 60 years; in the latter, this age limit is 65 years. This differentiation emerged during the First United Nations World Summit on Population Aging, through Resolution number 39/125(1). The need to establish chronological parameters for old age becomes more relevant as social and health actions are scheduled.
