Značajke nagiba i ravninske zakrivljenosti šireg područja Duvanjskog polja

In this paper, quantitative geomorphological features (slope inclinations, profile and planar curvature) of mountain rims of Duvanjsko polje were analyzed. Recent shape of this area is a consequence of series of natural and social impacts during relief genesis and evolution. The aims of this research are analysis of quantitative features of hillslope inclinations and curvatures of morphological units in wider Duvanjsko polje area, interpretation of results and synthesis, so more detailed insight in hillslope features and processes can be achieved and evaluation of nature of dominant geomorphological processes can be obtained. During this task, special attention was given to a detailed geomorphometric analysis in GIS environment based on a digital relief model. The analysis was conducted in several phases: 1. comparative analysis of hillslope characteristics based on morphological units, 2. comparative analysis of hillslope curvatures and 3. analysis of relationship between slope inclinations and curvature features. Synthesis included interpretation of obtained results in wider context of relationship between morphometric features and structural/lithological features of morphological units.U ovom su radu analizirane, kvantitativne geomorfološke značajke (nagibi padina, profil i ravninska zakrivljenost) planinskoga rubnog područja Duvanjskog polja. Na oblikovanje ovoga područja utjecalo je niz prirodnih i društvenih utjecaja tijekom geneze i evolucije reljefa. Cilj je ovog istraživanja analiza kvantitativnih obilježja nagiba padina i zakrivljenosti morfoloških obilježja šireg područja Duvanjskog polja, tumačenje rezultata i sinteze. Moguć je detaljniji uvid u značajke nagiba i odvijenih procesa, a moguće je postići i vrednovanje prirodno dominantnih geomorfoloških procesa. Tijekom istraživanja posebna je pažnja posvećena detaljnoj geomorfometrijskoj analizi u GIS okruženju, na temelju digitalnog modela reljefa. Analiza je provedena u nekoliko faza: 1. komparativna analiza karakteristika nagiba temeljena na morfološkim obilježjima, 2. komparativna analiza zakrivljenosti nagiba i 3. analiza odnosa između nagiba i značajki zakrivljenosti. Sinteza uključuje interpretaciju dobivenih rezultata u širem kontekstu odnosa između morfometrijskih značajki i strukturno/litoloških značajki morfoloških jedinica

The effect of interpolation methods on the quality of a digital terrain model for geomorphometric analyses

Danas su, bez obzira na rapidni razvoj tehnologije, većina prikupljenih (izmjerenih) podataka točkasti uzorci, dakle imaju točnu vrijednost odabrane varijable samo na izmjerenim x, y koordinatama. Da bi se dobile kontinuirane površine koje su neophodne za proučavanje, potrebno je procijeniti vrijednosti na neuzorkovanim područjima koristeći pritom različite metode interpolacije. Glavni cilj ovog istraživanja je vrednovanje dviju metoda interpolacije na kvalitetu digitalnih modela reljefa za potrebe geomorfometrijskih istraživanja. Za izradu modela i usporedbu metoda interpolacije korišten je skup visinskih podatka dobiven vektorizacijom izohipsi s HOK-a. Testirane su dvije metode interpolacije: triangulacijska nepravilna mreža (TIN) i ANUDEM (Topo to Raster). Za odabir prikladnije metode interpolacije korišteno je 8 statističkih parametara, grafički prikazi (dvodimenzionalni i trodimenzionalni), i geomorfometrijski parametar (nagib padina). Utvrđeno je da je ANUDEM bolja metoda za geomorfometrijska istraživanja od TIN-a. Analizom geomorfometrijskog parametra (nagib) zaključeno je da ne postoje značajnije razlike između DMR dobivenih iz različitih skupova visinskih podataka.Despite the modern technological advancements, contemporary methods of data gathering still rely on point samples, which means they feature a precise variable info only on specific x, y - coordinates. In order to get a continual representation of a surface necessary for research, it is necessary to approximate various data values on those surfaces which have not been sampled by using various methods of interpolation. The main aim of this research is to evaluate two different methods of interpolation based on the quality of digital terrain models used for geomorphometric analyses. For the purposes of developing and comparing these methods, a set of elevation data was attained by vectorization of contour lines from HOK. Two methods of interpolation were tested: triangulated irregular network (TIN) and ANUDEM (Topo to Raster). In order to get a more appropriate method, the research employed eight statistical parameters, various graphical representations (both two- and three-dimensional) and geomorphometric parameter of slope inclination. The research shows that ANUDEM is a better method for geomorphometric analyses than TIN is. After the analysis of geomorphometric parameters (slope), the conclusion is that there are no significant differences between the digital terrain models developed on the bases of different sets of elevation data

Physical Characteristics in the New Model of the Cerebrospinal Fluid System

It is unknown which factors determine the changes in cerebrospinal fluid (CSF) pressure inside the craniospinal system during the changes of the body position. To test this, we have developed a new model of the CSF system, which by its biophysical characteristics and dimensions imitates the CSF system in cats. The results obtained on a model were compared to those in animals observed during changes of body position. A new model was constructed from two parts with different physical characteristics. The »cranial« part is developed from a plastic tube with unchangeable volume, while the »spinal« part is made of a rubber baloon, with modulus of elasticity similar to that of animal spinal dura. In upright position, in the »cranial« part of the model the negative pressure appears without any measurable changes in the fluid volume, while in »spinal« part the fluid pressure is positive. All of the observed changes are in accordance to the law of the fluid mechanics. Alterations of the CSF pressure in cats during the changes of the body position are not significantly different compared to those observed on our new model. This suggests that the CSF pressure changes are related to the fluid mechanics, and do not depend on CSF secretion and circulation. It seems that in all body positions the cranial volume of blood and CSF remains constant, which enables a good blood brain perfusion

Modeling and implementation of an adaptive vehicle light management system

Suvremeni standardi u autoindustriji postavljaju sve više zahtjeve za sigurnost sudionika u prometu. Jedan od važnijih segmenata sigurnosti je zasigurno vidljivost ceste i okolnih objekata. Slabi uvjeti vidljivosti ugrožavaju sigurnost svih sudionika u prometu, a proizvođači taj problem rješavaju implementacijom sve naprednijih sustava svjetala u vozila. Glavna odlika takvih naprednih sustava je njihova interakcija s okolinom vozila i dinamička prilagodba uvjetima. U okviru ovog rada prikazan je proces razvoja prilagodljivog sustava za upravljanje svjetlima vozila kroz nekoliko ključnih faza. Obuhvaćene su faze modeliranja SWC-a, konfiguracija komunikacije, implementacija programskog koda, te simulacija i testiranje gotovog sustava. Sustav je izrađen po AUTOSAR modelu koristeći odgovarajuće metode i alate. Odabrane funkcionalnosti prikazanog rješenja daju pregled nekih od najčešće korištenih rješenja u današnjim sustavima za upravljanje prilagodljivim svjetlima.Modern standards in the automotive industry place increasingly demanding terms on the safety of road users. One of the most important segments of road safety is surely the visibility of the road and its surroundings. Poor visibility conditions endanger the safety of all traffic participants and the manufacturers are solving this problem by implementing increasingly advanced lightning systems in vehicles. The main feature of such advanced systems is their interaction with the surrounding of the vehicle and its dynamic adaptation to the conditions. This paper presents the process of developing an adaptive light control system of a vehicle via several key phases. Included are the phases of SWC modelling, communication configuration, program code implementation, as well as simulation and testing of the final product.
