This paper is aimed at just this target and it proposes a new controllable pitch propeller changing mechanism to be analysed, that would lead to lowering of energy consumption and by default to a reduction in the fuel consumption used by the diesel-generator.
In this case, the rotation moment of blade propeller corresponding to the unitary force will be: M = F ∙ b (2) Where: F - is the resultant of the forces acting on the sliding roller After processing the data, it will result that the maximum force is [5]: Fpmax = 13172 kgf Fig. 2 The kinematic scheme of pitch propeller mechanism Calculation of hydraulic cylinder Cylinder volume will be: Calculation of clutch The torsion moment to calculate the clutch is given by the relation: (3) where β – substitution coefficient β = 1,3 km – coefficient which considers the number of couplings per hour km = 0,9 kv – coefficient which considers the tangential speed on the medium-diameter circle kv = 0,8 Mr – the moment of

Computed parameters including material characteristics and process conditions (billet temperature. reduction ratio, and ram speed) were taken into consideration.
Simulations of upsetting tests will be performed to fit the model parameters by comparing with the corresponding experimental results and then used as input data for simulations of indirect extrusion processes.

Literature data [7] show, that skin-pass rolling with higher
reduction degrees of up to 10% improve the fish-scale resistance, but adversely affect mechanical
properties.
Lower reduction degrees would affect mechanical properties to a lesser extent, but in this case, the positive influence on fish-scale resistance vanishes.
In most cases, skinpass rolling of the hot-rolled materials with 2% reduction led to slightly lower susceptibility to fish-scale defect formation.
In most cases, cold-rolling leads to an increase in the number of precipitations per unit area, together with a reduction in the average particle size.

Injury severity by age groups based on data of Korean expressway has been studied.
The data contains general accident data such as the time and place of the accident occurrence, the characteristics of the suspect and the victim, the types of accidents, etc.
The accident data is then tabulated.

Furthermore, redundant point cloud data may also easily cause accumulation of errors during data processing.
Data Processing Pre-processing.
Data pre-processing includes read-in point clouds, noise processing and data reduction.
Efficiency is improved by regrouping features of parts on base of data partitioning.
As to data processing, workload of post processing is greatly reduced by simplifying measuring point clouds.

The results revealed that configuration II (MCH) exhibited complete ballistic resistance, meeting NATO AEP-55 STANAG 4569 level 1, while configuration III (Bim) demonstrated a higher velocity reduction compared to configuration I (COW).
The results of the chemical composition analysis are consistent with the manufacturer's material data sheet [26].
Configuration II achieved a complete reduction (100%) in the velocity of the 7.62 mm FMJ M80 projectile.
For configuration III, a reduction in projectile impact velocity of 64.18% and 67.74% was observed.
These results indicate that configuration II meets the requirements of NATO AEP-55 STANAG 4569, ballistic protection level 1, while configuration III demonstrates a higher velocity reduction compared to configuration I.

Research Methodology and Data Collection
The rainfall data analysed in this study were obtained from the Malaysian Meteorological Department and the Sabah Parks office.
The Malaysian Meteorological Department supplied daily rainfall data from the Sandakan Meteorological Station (Station ID: 5851001) for the period of 1st January 2003 to 31st December 2009.
However, it is duly noted that there is no rainfall data available in 1996 to 1997.
Results and Discussions The rainfall frequency analysis was done using the 27-year rainfall data (in Bakkungan Kechil island) and 28-year rainfall data (in Selingaan and Gulisaan islands) obtained from the gauging stations in the Turtle Islands Park.
By using daily rainfall data instead of monthly interval, the rainwater availability analysis may also be improved.

Data and methods
Data were collected from authorized distributors, importers, dealers, concessionaires and thus arrive at the results presented in the paper by certain car brands.
We used the statistical data collected by the Agency for identification documents, records and data exchange.
There are small differences in data on new cars sale in Bosnia and Herzegovina, depending on data source and for the analysis of new cars sold in Bosnia and Herzegovina for the period 2007-2014, the data from Web site: http://bihamk.ba/ [11] were used.
Data used in the table were extracted from yearly reports of BIHAMK and presented in an aggregated manner for easier interpretation.
If we analyze the data in 2014, there has been a decline in sales of 53.67% compared to 2007.

In the two types of the methods, the statistical methods have become more and more important because of their superb performance in processing large scale data.
Shahshahani[1] firstly worked on Semi-supervised learning with the unlabeled data.
In specific applications, we can adjust according to the requirement of indicator and data scale.
If the unlabeled data scale is enormous, we should consider human-annotation firstly, and should be smaller.

The second stage of the numerical analysis gives a basis for the reduction in the oxide scale model for engineering applications.
Thus, the reduction or adjustment in the model for desired technological operation is a final stage towards accurate prediction.
The main purpose of the most of measurements is to upgrade the numerical model with data reflecting properties that are more specific for the particular oxide scale under investigation and are critical for the analysis.
In hot „sandwich“ rolling, the slabs are closed together with the two scale layers trapped between the slabs, which can then be rolled at different temperatures and reductions.
The availability of experimental data exhibited that through-thickness cracking is an essentially brittle process of unstable crack propagation for majority of cases.
