We have designed and built a laminar microfluidic diffusion diluter (mDD) to obtain fixed concentration gradients inside lithographically patterned lab-on-a-chip architectures. The driving force for this investigation was the desire to minimize the amount of precious analyte consumed in high throughput measurements performed as a function of concentration.(More)
In this paper the modelling and Design of a Beam on which two Piezoelectric Ceramic Lead Zirconate Titanate (PZT) patches are bonded on the top and bottom surface as Sensor/Actuator collocated pair is presented. The work considers the Active Vibration Control (AVC) using Proportional Integral Derivative (PID) Controller. The beam is assumed as(More)
There is a growing trend of using cloud environments for ever growing storage and data processing needs. However, adopting a cloud computing paradigm may have positive as well as negative effects on the data security of service consumers. This paper primarily aims to highlight the major security issues existing in current cloud computing environments. We(More)
— In today's computational world,cost of computation is the most significant factor for any database management system.Searching a query from a database incurs various computational costs like processor time and communication time.Then, there are costs because of operations like projection, selection, join etc.DBMS strives to process the query in the most(More)
—The growing computing demand from industry and academia has lead to excessive power consumption which not only impacting long term sustainability of Grids like infrastructures in terms of energy cost but also from environmental perspective. The problem can be addressed by replacing with more energy efficient infrastructures, but the process of switching to(More)
—As routing tables in core Internet routers grow to exceed 100 000 entries, it is becoming essential to develop methods to reduce the lookup time required to forward packets toward their destinations. In this paper, we employ a bank of novel thermally tuned fiber-Bragg-grating-based optical correlators to construct an " optical bypass " to accelerate(More)
Firms are key drivers of urban growth along with households, yet data on businesses and commercial vehicle movements can be quite difficult to obtain. An understanding of firm behavior over time is critical in anticipating urban futures and addressing transportation, land use and other concerns. Firm birth and death, migration and location choice are(More)
–Rapid convergence of heterogeneous wireless communication technologies such as Wireless Local Area Networks (WLAN), Worldwide Interoperability for Microwave Access (WiMAX), Long Term Evolution (LTE) etc., attract new opportunities for collaborative usage. More and more applications are emerging to benefit from their advantages. However, with the range of(More)
