Modeling of stem cells not only describes but also predicts how a stem cell's environment can control its fate. The first stem cell populations discovered were hematopoietic stem cells (HSCs). In this paper, we present a deterministic model of bone marrow (that hosts HSCs) that is consistent with several of the qualitative biological observations. This(More)
Organizations today are moving towards cloud computing in order to reduce their upfront capital expenses. Typically, organizations have limited infrastructure with which they create a private cloud. If the number of user requests go beyond those that can be supported by the limited infrastructure, new user requests are denied. In order to overcome this(More)
A vehicular delay tolerant network (VDTN) is a special type of delay tolerant network (DTN), in which vehicles act as mobile nodes that are carriers of the message. It is characterized by the absence of an end-to-end connectivity between the nodes residing at the extreme ends. The routing in VDTN is critical as nodes are not connected permanently and the(More)
Vehicular Delay Tolerant Network (VDTN) has emerged as a special type of network that is distinguished by the non-existence of end-to-end path between source nodes and destination nodes. Routing is one of the crucial issues in VDTN. To route a message, it must be scheduled from the outgoing buffer of a node. This is also an important issue considering the(More)
With the advent of multicore processors, multiprocessor scheduling analysis for hard real-time systems has become an important problem. In such an analysis, consideration of overheads like Cache Related Preemption Delay (CRPD) is very much desired but not handled by most of the existing techniques. In this paper, we propose task partitioning methods that(More)
