AbstractThis article aims to provide the seafarer with a tool to calculate the deviation for a righted ship in any geographical position using only the information available on board. In this way the accidental errors in the deviation card are reduced and the latitude error is made negligible. Moreover, an experimental application of this method is carried out on board a tanker to compare the latitude error in different positions at sea.

Logistic center’s location for goods distribution in Republic of Srpska can be asserted on many parameters from whom two has vital importance: geographical position and size of traffic flow. Special significance of these center’s are logistical diversity, especially where different branches of traffics are involved. Starting factors for developing such a center in Republic of Srpska are position on roads, rails and corridors. Main purpose of these centers are command gathering, sendig commands to transport vehicles, depo good if necessary, forming transport units and delivery. There are seven main criteria: social, law regulation, ecological, technical, economics and organization. To define these criteria survey is used, also every criteria is evaluated. Applying ARAS (A new Additive Ratio Assesment) mathematical method Doboj city is determined to be optimal location for logistical center development.

Discriminatory Analysis

Administrative and medical information about the patient forms, in each case, a pattern, the complexity of which increases as the number of data grows. Even when the data are 4—5 in number, the human ability to recognize and distinguish between different patterns begins to fail, A mathematical method (linear discriminatory analysis) has been worked out. This system of analysis appears to provide opportunities of placing patients with the same or similar patterns in classes which are diagnostically, prognostically or therapeutically homogeneous.

The paper deals with the syntaxonomy of vegetation on the sandy outcrops in the Pechora (Malozemelskaya and Bolshezemelskaya) tundra. The vegetation was classified using the Brown-Blanke approach. Communities were referred to 3 associations: Arctostaphylo alpini—Empetretum hermaphroditi (Zinserling 1935) Koroleva 1994, Elymo—Festucetum arenariae (Regel 1923) Nordhagen 1955 and Rumici graminifoliae—Festucetum sabulosae ass. nov. Five new variants were suggested within the first association and 2 subassociations and 4 variants within the last one. Syntaxon description and phytocoenological tables are presented. The vegetation on each sandy outcrops represents a complex of communities fragmentary located on the scars area. Subass. inops of ass. Rumici graminifoliae—Festucetum sabulosae is more common in the Ortina river basin and occurs at the bottom of blowing hollows. Syntaxa of ass. Elymo—Festucetum arenariae and var. Festuca rubra of ass. Rumici graminifoliae—Festucetum sabulosae are situated at the mobile sands in the central part, while var. Arctous alpina of ass. Rumici graminifoliae—Festucetum sabulosae occurs on a periphery of out­crops where substratum is stable. The variants inops and typicum of ass. Arctostaphylo alpini—Empetretum hermaphroditi occuring in the Sedujyakha river basin occur mostly in the centre of sandy outcrops, and the other ones can be met on their periphery. Ecological conditions determine poor diversity of syntaxa of the association level. Geographical position (the Sedujyakha river basin belongs to the northern hypoarctic tundras, the Ortina river basin — to the southern hypoarctic ones), geomorphology (in the first site — tops of hills and ridges, in the second one — watershed areas) and area of sandy outcrops (200—3000 m2 for the first and 61000—418000 m2 for the second site respectively) are the reasons for the less diverse communities found in each study site. A great number of variants is conditioned by succession stages of vegetation and instability of the substrates.
