The main sources for power generation in Bosnia and Herzegovina are domestic coals, mainly lignite and brown coals, which are relatively characterized with a high content of sulphur (3-5%) and incombustibles (˜30%). From the 70’s, use of this type of fuels was not allowed in the city of Sarajevo due to very unfavorable emissions to the atmosphere, during the heating period, and since then Sarajevo has been supplied with natural gas. All the heating installations in the city were reconstructed and adapted. The district heating system Toplane Sarajevo is supplied with electrical energy from the Public electrical distribution network (Elektrodistribucija Sarajevo) at low voltage (0.4 kV). The boiler-house Dobrinja III-2 (KDIII-2), from the district heating system of Sarajevo Suburb Dobrinja, which was not in use after the war 1992-1995, had a lot of advantages for the reconstruction into the co-generation plant. The Government of Canton Sarajevo financially supported this proposal. An analysis of co-generations for the district heating system and a selection of most appropriate co-generation systems were made. In the proposed conceptual design, the co-generation KDIII-2 was located in the existing boiler-house KDIII-2, connected with the heating system in Dobrinja. The operating costs of production of electricity and heat were evaluated in the study and compared with the costs of conventional energy supply to the district heating system. This analysis resulted in economic indicators, which showed that this investment was economically viable, and it also determined the payback period of the investment. In this paper results of the mentioned study and an overview of co-generation in Bosnia and Herzegovina are presented.

We investigate the predictions for fermion masses in the min imal realistic non-supersymmetric SU(5) model with the Standard Model matter content. The possibili ty to achieveb− τ unification is studied taking into account all relevant effects. In additi on, we show how to establish an upper bound on the ultraviolet cutoffΛ of the theory which is compatible with the Yukawa couplings a t the grand unified scale and proton decay. We find Λ ≃ 10 GeV, to be considered a conservative upper bound on the cutoff. We also provide up-to-date values of all the fe rmions masses at the electroweak scale.

The main purpose of this study is to specify the basic perceptual dimensions underlying the judgments of the physical features which define the style in paintings (e.g. salient form, colorful surface, oval contours etc.). The other aim of the study is to correlate these dimensions with the subjective (affective) dimensions of the experience of paintings. In the preliminary study a set of 25 pairs of elementary perceptual descriptors were empirically specified, and a set of 25 bipolar scales were made (e.g. uncolored-multicolored). In the experiment 30 subjects judged 24 paintings (paintings were taken from the study of Radonjic and Markovic, 2004) on 25 scales. Factor analysis revealed the four factors: form (scales: precise, neat, salient form etc.), color (color contrast, lightness contrast, vivid colors), space (voluminosity, depth and oval contours) and complexity (multicolored, ornate, detailed). Obtained factors reflected the nature of the phenomenological and neural segregation of form, color, depth processing, and partially of complexity processing (e.g. spatial frequency processing within both the form and color subsystem). The aim of the next step of analysis was to specify the correlations between two groups of judgments: (a) mean judgments of 24 paintings on perceptual factors and (b) mean judgments of the same set of 24 paintings on subjective (affective) experience factors, i.e. regularity, attraction, arousal and relaxation (judgments taken from Radonjic and Markovic, 2005). The following significant correlations were obtained: regularity-form, regularity-space, attraction-form and arousal-complexity (negative correlation). The reasons for the unexpected negative correlation between arousal and complexity should be specified in further studies.

This paper discusses social robotics as a hybrid knowledge space that encourages interaction and collaboration among many different disciplines: engineering, computer science, the social sciences and humanities, design, the arts, etc. Such collaboration in the design of socio-culturally situated artifacts poses many challenges, occassioned by differences in conceptual frameworks, methods for conducting research, and even daily work practices. By approaching these challenges in a spirit of friendship across the sciences, it is possible to achieve transdisciplinary understanding and reap the benefits of applying different, yet complementary, forms of expertise to social robot design. In this paper, we use insights and lessons learned from our own collaborative experiences to discuss how social as well as technical and design issues are addressed in the construction and evaluation of social robots and how the boundaries between the social, natural, and applied sciences are challenged, redefined, and traversed.
