AN OVERVIEW OF DATABASES ON CONFLICTS AND POLITICAL CRISES

This paper provides overview of the important projects concerned with development of databases on conflicts, crises and similar political events and those dealing with the structural characteristics of nation-states. The different databases are usually differently conceptualized, even when they describe the same phenomenon. Different conceptualization of the problem leads to different operational definitions, and eventually to different coding rules. Therefore, the researcher intending to use existing data for the purpose of statistical analysis or modelling the social processes can became lost browsing the multitude of different datasets. In this overview, the short descriptions of important data-gathering project include information on the institution where the project is placed, its principal investigators, year span and number of cases it includes. In the end all mentioned databases are classified according the focus (event/structure) and the level (nation-state/international relations) of observation

An Image Processing System for Visual Servoing of Soccer Robot

In this project, presents a global system for mapping and tracking of the movement of some of Soccer Robot using image processing for color filters of the robot and labeling marker for mapping the position of each robot. Robot's marker consists of a combination of two colors as the robot and team identity. To generate a global information, Camera placed on the robot soccer field. Feedback resulting from the coordinate information and soccer robots feature on Soccer games in real time. Output data in the form coordinate position of the ball, robots, and headings. Data will be processed and sent to the robot to control the movement and strategy on the soccer robots

Selection of autofocus algorithms for printed circuit board automated optical inspection system

This paper presents an examination study of 11 autofocus algorithms for printed circuit board (PCB) automated optical inspection (AOI). A selection of an optimal algorithm for that application based on some criteria was carried out. Unlike microscopy, PCB optical inspection does not require very high magnification. The object in this work was also different from that of microscopy and thus influenced the image features. We analyzed 47 PCB images, size of 640×480, sequentially captured every 1 mm in the z-direction. This work utilized USB digital microscope, and the magnification was set at ten times. Each algorithm calculated the sharpness values of the image sequences, and the plot of the sharpness profile was created. Moreover, the research also carried out experiments in several strategies, including image resizing and applying the non-local means (NLM) denoising filter to assess the algorithm performance in different situations. The algorithms were examined and ranked based on five criteria, i.e., computation time, full width at half maximum (FWHM), accuracy, number of half maxima, and range. The experimentation results showed that the Brenner gradient worked best for analyzing images both in their original dimension or resized images

An Overview of Databases on Conflicts and Political Issues

Mary Rose or on Useless Weapon

Ovaj rad nastoji smjestiti poblem oblikovanja i odabira oružja u njegove društvene, kulturne i psihološke okvire. Osnovna pitanja koja se u radu postavljaju jesu: može li odabir oružja biti iracionalan i, ako može, kada on takvim postaje? Razmatranjem nekih neutilitarnih faktora koji, ovisno o kontekstu, imaju veći ili manji utjecaj na odabir oružja, oslikava se kompleksnost problema i pokušava se izbjeći nekritičko pridijevanje pojma “iracionalno”. Na temelju brojnih povijesnih primjera i nekih već postojećih razmatranja daje se pozitivan odgovor na postavljeno pitanje. Odabir oružja postaje iracionalan kada zahtjevi koji bi trebali biti sporedni (primjerice estetski) dobiju prioritet te oružje postane jednostavno neupotrebljivo.This paper tries to place the problem of creation and the choice of weapon in its social, cultural and psychological frameworks. Basic questions made in the paper are: can the choice of weapon be irrational, and if so, when does it become irrational? Consideration of some non-utilitarian factors which, depending on the context, have larger or smaller impact on the choice of weapons, portrays the complexity of the problem and tries to avoid the uncritical supplement of the term “irrational”. On the basis of numerous historical examples and some existing studies we can give the affirmative answer to the question. The choice of weapon becomes irrational when demands that should be subordinate (for example, aesthetic) have priority and, thus, the weapon becomes simply useless
