In this work we research convergence rates of densities of independent random extreme values. Using [4] and [2] work results, we will get nonuniform estimate of convergence rates in local theorem of extreme values of independent random variables exploring different distribution functions. [4], [2] work results we will generalize exploring nonuniform normalized extreme values convergence.

Theory of extreme values is very important and it’s use of range is very wide. A lot of research occurrence usually is described with a few measurements (for example, testing pollution of atmosphere, usually consider all superior limits of pollution concentration, not only one war gas maximum concentration) that’s why are analyzing multidimensional extreme values. Herein work we analyze convergence rate of the multidimensional extreme values in the transfer limit theorem. We solve this problem using particular distributions. In this work we will give nonuniform estimate of convergence rate of multidimensional extreme values in the transfer limit theorem.

Herein work is analyzing convergence rate in transfer theorems for extreme values of independent identically distributed random variables. Analyzing various distributions is god nonuniform estimate of convergence rate in transfer theorems. Transfer theorem of density of minima have been proved. Analyzing convergence rate in transfer theorems of density for extreme. Computation was developed using SAS and Mathcad.

This Master Thesis involves the analysis and evaluation of military students psychomotor processes. This was carried out using the analyzer DPA – 1. This device is used for measuring dynamic parameters of independent or coordinated arm and leg movements by reacting to the target with a variety of geometric, colour or time parameters appearing on the screen. The DPA – 1 device enables scientists to analyse psychomotor reaction and dynamic and kinematical characteristics. The goal of the research was to identify the peculiarities of psychomotor reaction performing movements with the right and left arms. The participants of the research were 40 students (n=40) of the Lithuanian Military academy. Their age was 22.03 ± 0.54 years, body mass – 76.04 ± 9.13 kg, height – 180.29 ± 7.99 cm. Their right arm was dominant. To achieve this goal the following tasks had to be completed: 1. To determine the differences in psychomotor reaction by performing the moves with the dominant and non-dominant arms. 2. To determine the difference between movement speed and accuracy by performing the movement with the right and the left arms. 3. To determine the connection between the parameters of psychomotor reaction of the right and the left arms. The hypothesis: We think that movements performed with the dominant arm have better psychomotor qualities. The research methods: 1. Analysis of the scientific literature resources 2. Testing 3.

The objective of this study was to determine sprint athletes and non–athletes girls acute muscles and heart adaptation peculiarities to multiple anaerobic loads. The study‘s participants were girls of similar age: 5 trained athletes in sprint events and 5 non–athletes. There were estimated their antropometric parametres, assessed body mass index (BMI) and heart rate at rest. Also participants performed multiple anaerobic workloads. The results of this research showed that girls well–trained athletes managed to perform greater extent of physical load, were less tired and managed faster to recover between reiterations. The non–athletes performed significantly lower extent of physical load and before the third workload their heart rate‘s indices and results of running 10 m distance with 10 % of body mass weighting indicated considerable fatigue. In consideration of long term adaptation effect we propose, that well–trained athletes have lower body mass, BMI, heart rate at rest, higher running velocity and greater increase of velocity compare to non–athletes. Eaqual duration, intensity, rest pauses and the number of reiterations with and without weighting have different effect on muscle working ability. Athletes showed greater running velocity and it remained unaltered during reiterations in performing eaqual workload without weighting. Participants reached lower velocity and there were obtained velocity reduction in performance with weighting.

Work purpose – to determine permanent quickness and power manual loads influence on skeleton muscle anaerobic potential. 11 of the best Lithuanian short distance runners and 8 persons, who do not go in for sports, were attending in research. Also, there were used adequate testing results and trainings processes information of 8 world short distance runners. They took anthropometrical information measurements from researched, body mass index was estimated (BMI), maximum and comparative legs muscles power was assessed, maximum running and 60m drubbing speed measured. Gained results showed that the best world short distance runners reached better maximum running speed, but maximum and comparative muscles power indicators were not differ from Lithuanians short distance runners. Persons, who do not go in for sports, maximum and relative powers and maximum running speed meaning in worse than researched Lithuanian short distance runners, who go in for sports. When they were running 60m only 10m they were going faster than the best world short distance runners. Persons, who do not go in for sports run 60m distance slower than other researched group members. They also reached slower speed increase and after 50m they got tired. When the best Lithuanian short distance runners of annual training facts were analyzed then came out that in annual training cycle was applied more exercises which needed power and had higher power indicators. Thus, Lithuanian short distance runners faster run 6... [to full text]

Most countries for constructing low-rise buildings apply mostly wood in manufacturing of various structures (bearing structures of roofs, walls, beams, columns and etc.). In cases of fire these buildings manifest mostly such evidences of burning which are called charring of wooden parts (structural elements). For investigators of fire it is relevant to find the connection of this feature with certain significant effects of fire, namely its duration or temperature, in order to be able to determine the exact location of the fire start (spot/source) as well as the cause of initiation (reason). The dynamics of fire aggravates the determining of accuracy of determining the duration of wood burning, because in wooden structures there are enacted many additional physical-chemical processes. These processes make a great influence on fire resistance of structures, on the influence of the knowledge on different fields. Well known professionals consider that the attention to charring rate under the analysis of fire is paid a too narrow one and played as inadequately considerable role. In our country there have been so far applied the remarks and recommendations of Russian scientists, regarding charring rates, there are presented generalized charring rates of wood, the particularity of coal layer measurements is discussed, the calculation of burning duration taking into account theoretical and instrumental methods , however without mentioning the influence of majority of factors...

Kilus gaisrui tokiuose pastatuose, labiausiai iš visų degimo požymių yra pastebimas medžio detalių (konstrukcijos elementų) apanglėjimas. Gaisro tyrinėtojams ypač aktualu susieti šį požymį su tam tikrais svarbiais gaisro poveikiais, pvz., jo trukme ar temperatūra, kad būtų galima nustatyti tikslią gaisro kilimo vietą (židinį) bei kilimo būdą (priežastį). Gaisro dinamika apsunkina medienos degimo trukmės nustatymo tikslumą, nes medinėje konstrukcijoje vyksta daug papildomų fizikinių-cheminių procesų. Šie procesai daro didelę įtaką konstrukcijų atsparumui ugniai, o šios įtakos tyrimams reikalingos skirtingų mokslo šakų žinios. Autoritetingi specialistai mano, jog, tiriant gaisrus, apanglėjimo greitis yra nepakankamai įvertinamas ir skiriama jam per mažai dėmesio. Mūsų šalyje naudojamose Rusijos mokslininkų rekomendacijose pateikiami apibendrinti medienos apanglėjimo greičiai, aptariama anglies sluoksnio matavimo specifika, teoriniais bei instrumentiniais metodais apskaičiuojama degimo trukmė, tačiau neįvardijama svarbių veiksnių įtaka.
