Separating cells from a mixed sample is a required task in biotechnology and modern medicine, for example to isolate CTC’s that are of interest for doing therapy and diagnosing or doing research. A minute percentage of target cells must be separated from a large amount of unwanted cells. These target cells like CTC’s could be as rare as 1 target cell per millions of unwanted background cells. Hence Microfluidic cell sorting schemes based upon fluorescent labelling, electrophoresis, dielectrophoresis and magnetophoresis have been devised. Microfluidic magnetically-activated cell sorting (MACS) does not need any optical instrument or current source and electrode. By using an electromagnet or... 

The number of transistors on a single chip is growing exponentially which results in a huge increase in consumed power and temperature. Parallel processing is a solution which concentrates on increasing the number of cores instead of improving single thread performance. Graphics Processing Units (GPUs) are parallel accelerators which are categorized as manycore systems. However, recent research shows that their consumed power and energy are increasing. In this research, we aim to propose methods to make GPGPUs energy effiecient. In this regard, we evaluated the detailed consummed power of GPGPUs. Our results show that memory sub-system is a critical bottelneck in terms of performance and... 

The basis of the current IP-based networking architecture is on addressing locations (IP addresses). This way of locating and searching content does not meet the existing applications’ demands for generating and consuming larger data. In order to confront this problem, Named Data Networking (NDN) has been proposed that allocates names to data instead of the location. This fundamental change improves the functionality of the network in terms of various aspects such as smoother mobile routing, higher security, intrinsic multicast, broadcast system, and enables caching at the network level. As data directly receives an address in NDN, it can reside anywhere in the network. Furthermore, content...
