    Finance And R&D Investments - Is There A Debt Overhang Effect On R&D Investments?

    The motivation of this paper is the rather naive approach to debt as a financing source of R&D investment in the empirical investment literature. The author focuses on long-term relational debt based on its appealing contractual properties and discovers a debt overhang effect for the relationship between additional long-term debt...

    Ownership Structure, Board Composition And Investment Performance

    In this paper the relation between ownership structure, board composition and firm performance is explored. A panel of Swedish listed firms is used to investigate how board composition affects firm performance. Board heterogeneity is measured as board size, age and gender diversity. The results show that Swedish board of directors...

    Automated Multidimensional Characterization of Power Amplifier for Design and Production

    Designing, optimizing and producing modern Power Amplifiers (PA) requires new and fast RF (Radio Frequency) measurement techniques capable of characterizing its real behavior. PAs are a truly multidimensional device where many desired performance parameters are contradictory to each other. This is especially true for the generation of modern communication PAs...

    High-Level Estimation and Trade-Off Analysis for Adaptive Real-Time Systems

    The authors propose a novel design estimation method for adaptive streaming applications to be implemented on a partially reconfigurable FPGA. Based on experimental results they enable accurate design cost estimates at an early design stage. Given the size and computation time of a set of configurations, which can be derived...

    Strategic Business and IT Alignment: A Prioritized Theory Diagram

    Many academic and practitioners' studies have shown that misalignment or lack of alignment between Information Technology (IT) and business strategies is one of the main reasons why enterprises fail to exploit the full potential of their IT investments. Furthermore, organizations that have accomplished a high degree of alignment are often...

    Run-Time Partitioning of Hybrid Distributed Shared Memory on Multi-Core Network-on-Chips

    On multi-core Network-on-Chips (NoCs), memories are preferably distributed and supporting Distributed Shared Memory (DSM) is essential for the sake of reusing huge amount of legacy code and easy programming. However, the DSM organization imports the inherent overhead of translating virtual memory addresses into physical memory addresses, resulting in negative performance....

    Exact Optimized-cost Repair in Multi-hop Distributed Storage Networks

    The problem of exact repair of a failed node in multi-hop networked distributed storage systems is considered. Contrary to the most of the current studies which model the repair process by the direct links from surviving nodes to the new node, the repair is modeled by considering the multi-hop network...

    Repair for Distributed Storage Systems with Erasure Channels

    The authors study the repair problem of distributed storage systems in erasure networks where the packets transmitted from surviving nodes to the new node might be lost. The fundamental storage-bandwidth tradeoff is calculated by multicasting analysis in erasure networks. The optimal tradeoff bound can be asymptotically achieved when the number...

    Analysis and Evaluation of Circuit Switched NoC and Packet Switched NoC

    Circuit switched NoC has, compared to packet switching, a longer setup time, guaranteed throughput and latency, higher clock frequency, lower HW complexity, and higher energy efficiency. Depending on packet size and throughput requirements they exhibit better or worse performance. In this paper, the authors designed a circuit switched NoC and...

    Scalability Analysis of Release and Sequential Consistency Models in NoC based Multicore Systems

    The authors analyze the scalability of the Release Consistency (RC) and Sequential Consistency (SC) models which are realized in the Network-on-Chip (NoC) based distributed shared memory multicore systems. The analysis is performed on the basis of workloads mapped on the different sizes of networks with different data sets. The experiments...
