This paper introduces a design and optimization procedure for active and semi-active non-linear suspension systems regarding terrain vehicles. The objective of this approach is the ability to quickly analyze vehicles\u27 suspension performances resulting from passive, active, or semi-active systems. The vehicle is represented by a mathematical model regarding a quarter of it, and equations for motion are derived and solved by using MATLAB/Simulink. In order to verify the reliability of the derived computer program, a comparison is made with one of the comprehensive commercial software packages. The decision parameters of the active damping device are optimized by using the Hooke-Jeeves method, which is based on non-linear programming. The usefulness of the treated active and semi-active systems on a concrete terrain vehicle is presented and compared with the presented passive systems by analyzing the vehicle\u27s body acceleration, velocity, displacement, and vertical tire force, namely those aspects that directly influence driving comfort and safety.Za terenska vozila je značilno zelo veliko premikanje koles v vertikalni smeri, saj se s tem prepreči nevarnost prevračanja, ko vozilo potuje po neravnem terenu. Zaradi te značilnosti morajo imeti terenska vozila učinkovit sistem obes, saj morajo potnikom pri vožnji zagotavljati tudi ustrezno udobje in varnost. Konstruktorji vozil posvečajo veliko pozornost tako oblikovanju obes kakor tudi njihovi optimizaciji, vse z namenom, da bi izboljšali vozne lastnosti. Osnovni namen sistema obes je zagotoviti dober kontakt koles z neravno podlago, kar je možno izvesti samo z bolj ali manj kompliciranim sistemom obes

The reduction in greenhouse gas emissions and the decarbonization of the power sector through the utilization of available renewable technologies are challenging issues that Kosovo has to tackle right now, in order to fight the high pollution caused by a coal-based power system. Around 91.43% of installed capacities for electricity generation in Kosovo are based on coal-fired power plants. The aim of this paper is to show the potential for renewable utilization, using data measurements of wind, solar irradiation, biomass, and average water flows at different area locations to identify their utilization potential. Furthermore, a review on the currently available and future renewable energy projects integrated into the electricity sector is presented. A 54% carbon dioxide emission reduction potential was estimated in the power sector when considering maximum utilization potential of biomass, wind, solar renewable energies compared to a referent scenario. The results obtained from this review have shown the pathways for identifying the potential utilization of renewable as well as the actual and planned use of renewable implemented projects into the Kosovo Power Sector.

Profundus [FDPs]) following surgical repair and in partially divided FDPs without surgical repair, and to compare the results of the repair versus the nonrepair of zone two injuries via macroscopic and biomechanical evaluations of tendon adhesions. Methods: We used 32 adult male European rabbits (Oryctolagus cunniculus) weighing from 2.5 to 3.5 kg. The study was performed on the deep flexor tendons of the second and third digits of the right hind paws of the rabbits; thus, a total of 64 tendons were examined in this study. Results: Based on the results achieved in our experimental study, the load (N) significantly increased in subgroup 1a in which the tendons were surgically repaired and were not treated with 5-FU compared with subgroup 2a in which tendons were surgically repaired and treated with 5-FU. Conclusions: The load (N) significantly increased in subgroup 1a in which the tendons were surgically repaired and were not treated with 5-FU compared to subgroup 2a in which the tendons were surgically repaired and treated with 5-FU. Therefore, these results revealed a decrease in adhesion formation in the subgroup that was treated with 5-FU due to increased resistance to tendon adhesions during their excursion through the tendon sheath, which in this case required greater traction force....

Urban wind Energy is one of the new renewable ways of producing electricity, which researchers have not studied very much. From earlier studies, it is impossible to state if it is or is not recommended to install wind turbines in Urban Areas. Further inverstigation are required to have a more accurate answer, including wind potential, suitability and possibility of installation.
