The Four Valleys was revealed in Bagdad in a mystical language and style, in response to a request made by a prominent Sufi. Yet, despite the traditional Sufi concepts, language, and symbolism employed by Bahá’u’lláh, studying the text in light of the totality of Bahá’í writings demonstrates that its main purpose is to guide the wayfarers to the recognition of the Manifestation of God, soon to be revealed to be Bahá’u’lláh Himself. Furthermore, understanding the text as portraying two complementary paradigms—four parallel paths towards God and the four stages of a single path—leads to integrative and holistic perspectives and practices prescribed in the Bahá’í writings.

Abstract In this paper, an algorithm for multipath connection provisioning in elastic optical network (EON) has been proposed. Initially, the algorithm prefers the single-path routing for service provisioning. But when single-path routing is not adequate to serve a dynamic connection, the algorithm switches to the connection request fragmentation. Its computation is based on the parameters such as capacity_constant and capacity_allowed to fragment the connection request on disjoint paths. Simulation results clearly state that the proposed algorithm performs well in service provisioning as compared to the traditional single-path routing algorithms and improves the average network throughput. Thereafter, we have investigated the limitation of Erlang B traffic model in EON for calculation of link blocking probability using routing and spectrum assignment (RSA) algorithm. It is verified by the following two ways: (i) effect on the blocking probability in case of constant load and (ii) effect of slot width on the blocking probability. Our simulation results indicate that in EON due to dynamic RSA, blocking probability is not constant in case of proportionate varying of call arrival and service rate giving constant load and blocking probability depends on the number of slots per link, but in Erlang B traffic model blocking probability is always constant in case of constant load and it considers wavelength per link instead of slots per link. This is attributed to the fact that Erlang B traffic model fails to calculate blocking probability accurately in EON. We have computed the carried traffic on 14 nodes, 21-link National Science Foundation Network (NSFNET) topology.

The new technologies born from academic research can be very promising, yet they are often very early stage. University spin-off companies are uniquely positioned to tackle the risks associated with new technologies emerging from academia by developing proofs of concept, functioning prototypes, and new products. While these enterprises start from a solid research and development foundation, they face their own unique set of challenges—they are strongly anchored in the scientific and technological expertise that is typically backed by intellectual property but often lack the business experience needed to develop and market products demanded by customers. University spin-offs have access to substantial non-dilutive funding that can be utilized for advancing product development. While the relentless pursuit of these funds builds a company's credibility and improves its position for negotiating future private investment, university spin-offs would greatly benefit from an early focus on complementing their technology teams with their business teams. These new enterprises should consider pursuing private investment in parallel to utilizing sources of non-dilutive funding. Timing of private investment is extremely important to maximize the value of the opportunity, and, therefore, building relationships with investors early on and getting ready for executing an investment round can greatly increase odds for success. While there is no single path to formulate, pursue, and adapt successful financing strategies, lessons can be learned from real-life cases of university spin-offs that continue their journeys towards ultimate success.

Networks on Chips (NoCs) are required to tackle the increasing delay and poor scalability issues of bus-based communication architectures. Many of today's NoC designs are based on single path routing. By utilizing multiple paths for routing, congestion in the network is reduced significantly, which translates to improved network performance or reduced network bandwidth requirements and power consumption. Multiple paths can also be utilized to achieve spatial redundancy, which helps in achieving tolerance against faults or errors in the NoC. A major problem with multipath routing is that packets can reach the destination in an out-of-order fashion, while many applications require in-order packet delivery. In this work, we present a multipath routing strategy that guarantees in-order packet delivery for NoCs. It is based on the idea of routing packets on partially nonintersecting paths and rebuilding packet order at path reconvergent nodes. We present a design methodology that uses the routing strategy to optimally spread the traffic in the NoC to minimize the network bandwidth needs and power consumption. We also integrate support for tolerance against transient and permanent failures in the NoC links in the methodology by utilizing spatial and temporal redundancy for transporting packets. Our experimental studies show large reduction in network bandwidth requirements (36.86% on average) and power consumption (30.51% on average) compared to single-path systems. The area overhead of the proposed scheme is small (a modest 5% increase in network area). Hence, it is practical to be used in the on-chip domain.
