Solar energy is directly converted into electrical by using photovoltaic (PV) panels. The efficiency of PV panel varies with its orientation and tilt angle the horizontal plane. In this paper, we investigate optimum solar panels installed at Sukkur IBA University. for tilted surfaces varying from 0° to 90° in steps 1° was calculated values which daily total radiation maximum a specific period. ...

Dieses Paper gibt einen Einblick in Algorithmen der künstlichen Intelligenz – im Speziellen Algorithmen, die ihren Einsatz in Computerspielen finden. In einer Einleitung werden die Grundzüge künstlicher Intelligenz vermittelt. Es folgt eine Motivation, die zeigt, wozu man sie in Computerspielen benutzen kann und warum “Intelligenz” in Spielen notwendig ist. Nach einem kurzen Blick in die Entwic...

Klasse von probabilistischen Optimierungsverfahren, die “Ideen” der natürlichen Evolution nutzen. Wegen ihrer Universalität und Robustheit eignen sie sich besonders für komplexe Optimierungsprobleme bei denen klassische Optimierungsverfahren versagen. Der Artikel stellt die Arbeitsweise der Evolutionären Algorithmen am Beispiel des LKW-Einparkens vor, diskutiert die Vorund Nachteile des Verfahr...

Muscles of individuals with a spinal cord injury (SCI) exhibit an unexpected leftward shift in the force (torque)-frequency relationship. We investigated whether differences in torque-angle relationships between SCI and able-bodied control muscles could explain this shift. Electrically stimulated knee-extensor contractions were obtained at knee flexion angles of between 30 degrees and 90 degree...

Abstract Stretch flangeability tests are performed on cold rolled AHSS automotive steel grades for crack sensitivity evaluation. The ISO16630 procedure is used with different cutting edge conditions including clearance, tool wear, angle and hole expansion punch geometry. Among all influence parameters, the clearance considered to be most critical control. Low (<10%) high (>20%) clearances...

Deformation behaviour during loading and unloading is studied in compression of an aluminium plate with a high ratio between the diameter thickness by DLC coated die. A compressed becomes thinner after to larger reduction loading. The plastic deformation confirmed measuring increase unloading. optimum profile die crown approaches reverse shape elastic deflection flat at stroke end increasing th...

Poly (3,4-ethylenedioxythiophene)-poly (styrenesulfonate) (PEDOT:PSS) was coated on flexible polyethylene terephthalate (PET) substrate using slot die on a roll-to-roll (R2R) system under different web tensions. The electrical resistance, the standard deviation of the recorded resistance and surface roughness of the coating under different tensions were analyzed. Based on these data an optimum ...

Equal-channel angular pressing (ECAP) combined with the Conform process provides a solution for the continuous production of ultrafine-grained materials. In the present study finite element method was executed to investigate the effects of die channel angle and friction on the strain homogeneity and the required torque in ECAP-Conform process. Deformation behaviour of Al 6061 wires was analyzed...
