Impulse Radio Pulse Shaping for Ultra-Wide Bandwidth UWB Systems

In this paper, we investigate the design of pulse shaping UK filters for impulse radio ultrawideband (UWB) communications systems. The goal of the shaping is to meet an arbitrary spectrum mask, e.g., the mask mandated by the FCC for UWB emissions. Compared with classical FIR filter designs, the current problem introduces three new challenges: (1) it is minimax with quadratic constraints, (2) a sin

Based on a survey of waste sorting behaviours and perceptions of residents in southern Sweden, we discuss how physical environment, gender and knowledge affect the actual sorting activities.

Supply Chain Designs for Preparedness

Purpose of this research The ability to quickly respond presupposes logistics systems designed to be responsive; supply chains must prepare to act if specific circumstances occur. By investigating ‘preparedness’ in a defence logistics context, the overall research objectives are to define ‘preparedness’ and to advance defence logistics as an academic research area. Design/methodology/approach We
