This study aims to expand our understanding of environmental performance by adopting exploration and exploitation concepts, which are key types of firm innovation. We reveal exploration and exploitation as two important antecedents of proactive and reactive environmental performance. We also identify the conditions under which the distinct effects of these two types of innovation are moderated....

Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...

The textile dyes are considered as major environmental problems. The dyes can be removed by various methods. Therefore, this study aimed to evaluate the adsorption rate of Reactive Red 198 (RR198) from aqueous solution by activated Azolla filiculoides. This was an empirical-lab study. The Azolla was used as an adsorbent to remove Reactive Red 198 dye. The effect of various parameters was invest...

Mobile ad Hoc networks (MANETs) can make dynamic changes in topology. The most realistic characteristic which differentiates MANETs from other networks is that it is capable of changing its location. The result of the surveys over the last 5 years, show that it can overcome the two difficulties such as congestion and communication between nodes. Different routing algorithms are used while maxim...

Futbolun talepleri son zamanlarda önemli ölçüde değişmiş ve artmıştır. Günümüzde bir futbol müsabakası sırasında, oyuncuların daha fazla güce sahip olmaları, yüksek şiddet gerektiren hareketleri sık sayıda yapmaları uzun mesafeleri kat etmeleri gerekmektedir. Bu çalışmanın amacı futbolcuların sprint, çeviklik reaktif performansları arasındaki farklılıkları araştırmaktır. Çalışmaya toplam 59 erk...
