LTCC System for High Frequency Applications

Using LTCC (Low temperature co-fired ceramics) system in wireless packaging applications is wide used today. The properties requirements for wireless applications are requiring low loss at high frequencies and good characteristic comparative to cost. Several designs of packaging systems are presented in various microwave packaging applications such antenna. The relative curves of dielectric con...

Dendritic SK channels convert NMDA-R-dependent LTD to burst timing-dependent plasticity.

Feedback and descending projections from higher to lower brain centers play a prominent role in all vertebrate sensory systems. Feedback might be optimized for the specific sensory processing tasks in their target brain centers, but it has been difficult to connect the properties of feedback synapses to sensory tasks. Here, we use the electrosensory system of a gymnotiform fish (Apteronotus lep...

This paper presents experimental results generated through a program of shake-table testing of simple frames through collapse. Fifteen four-column frame specimens were subjected to progressive unidirectional ground shaking as structural response was measured. The specimens were subdivided into groups of three different column slenderness ratios: 100, 150, and 200. Within each group, column dime...

Equipment capacity optimization of an educational building’s CCHP system by genetic algorithm and sensitivity analysis

Combined cooling, heating, and power (CCHP) systems produce electricity, cooling, and heat due to their high efficiency and low emission. These systems have been widely applied in various building types, such as offices, hotels, hospitals and malls. In this paper, an economic and technical analysis to determine the size and operation of the required gas engine for specific electricity, cooling, ...
