Composite materials are widely used in the various Fields. Due to the high strength they are widely used in the low weight constructions and also used as a suitable alternative to metals. In various applications and also for joining various composite parts together, they are fastened together using adhesives or Mechanical fasteners. Modeling and static analysis of 3-D Models of joints such as b...

Fuel cell vehicles are the subject of extensive research and development because of their potential for high efficiency and low emissions. Because fuel cell vehicles remain expensive and the demand for hydrogen is therefore limited, very few fueling stations are being built. To try to accelerate the development of a hydrogen economy, some original equipment manufacturers (OEM) in the automotive...

The possibility to combine silica photonic crystal fiber (PCF) as low-loss platform with advanced functional materials, offers an enormous range of choices for the development of fiber-based tunable devices. Here, we report a tunable hybrid silica PCF with integrated As2S3 glass nanolayers inside the air-capillaries of the fiber based on a solution-processed glass approach. The deposited high-i...

In this paper, hybrid modeling of Micro-strip antenna is presented. Broadband frequency of operation demonstrated by single geometry .for broadening the bandwidth and maximum directional gain (6.6dBi 8dBi) gap-coupled multi-resonator loaded on parasitic and active patch. The geometry of a single probe fed rectangular Micro-strip antenna incorporating a slot and gap coupled with parasitic and ac...

Hybrid Vehicles (HVs) are proposed as a candidate to conventional vehicles. Characteristic for HVs is the use of a temporary energy buffer. But the control of the Primary Power Unit (PPU), e.g. an otto engine or a fuel cell, is much more complex than in conventional vehicles. This paper deals with a method to design a control algorithm for the PPU in a HV. Here, a Finite State Machine (FSM) is ...

We have reviewed the rate of revision of fully cemented, hybrid and uncemented primary total hip replacements (THRs) registered in the New Zealand Joint Registry between 1999 and December 2006 to determine whether there was any statistically significant difference in the early survival and reason for revision in these different types of fixation. The percentage rate of revision was calculated p...

Hybrid plasmonic (HP) modes allow strong optical field confinement and simultaneously low propagation loss, offering a potentially compact and efficient platform for on-chip photonic applications. However, their implementation is hampered by the low coupling efficiency between dielectric guided modes and HP modes, caused by mode mismatch and polarization difference. In this work, we present a m...
