Globally Asynchronous Locally Synchronous Architecture for Large High-performance ASICs

Clock nets are the major source of power consumption in large, high-performance ASICs and a design bottleneck when it comes to tolerable clock skew. A way to obviate the global clock net is to partition the design into large synchronous blocks each having its own clock. Data with other blocks is exchanged asynchronously using handshake signals. Adopting such a strategy requires a methodology that

Modeling Analysis of Different Renewable Fuels in an Anode Supported SOFC

Background. It is expected that fuel cells will play a significant role in a future sustainable energy system, due to their high energy efficiency and possibility to use renewable fuels. Fuels, such as biogas, can be produced locally close to the customers. The improvement for fuel cells during the last years has been fast, but the technology is still in the early phases of development, however th

Sensorless Friction-Compensated Passive Lead-Through Programming for Industrial Robots

Industrial robots are important when the degree of automation in industry is increased. To enable the use of robots also when the products change rapidly, the programming must be quick and easy to perform. One way to accomplish this is to use lead-through programming, i.e., the user manually guides the robot. This paper presents a sensorless approach, and thus avoids the need for a typically expen

Sparse Chroma Estimation for Harmonic Non-Stationary Audio

In this work, we extend on our recently proposed block sparse chroma estimator, such that the method also allows for signals with time-varying envelopes. Using a spline-based amplitude modulation of the chroma dictionary, the refined estimator is able to model longer frames than our earlier approach, as well as to model highly time-localized signals, and signals containing sudden bursts, such as t

Är du genuskompetent? Kampen om genuscertifiering vid svensk universitet

Analysis of gender certification (genuscertifering) policies and actions at Lund, Uppsala and Umeå universities. Lund began a pilot program, Umeå used it as marketing strategy and Uppsala rejected the measures for further gender-based governance. Chapter to appear an anthology on Swedish higher education

On The Distribution of Linear Biases: Three Instructive Examples

Despite the fact that we evidently have very good block ciphers at hand today, some fundamental questions on their security are still unsolved. One such fundamental problem is to precisely assess the security of a given block cipher with respect to linear cryptanalysis. In by far most of the cases we have to make (clearly wrong) assumptions, e.g., assume independent round-keys. Besides being unsat
