The paper investigates the reduction of dynamic power for streaming applications yielded by asynchronous dataflow designs by using clock gating techniques. Streaming applications constitute a very broad class of computing algorithms in areas such as signal processing, digital media coding, cryptography, video analytics, network routing and packet processing and many others. The paper introduces a
The growing complexity of digital signal processing applications make a compelling case the use of high-level design and synthesis methodologies for the implementation on programmable logic devices and embedded processors. Past research has shown that, for complex systems, raising the level of abstraction of design stages does not necessarily come at a penalty in terms of performance or resource r
Dataflow programming is a paradigm for describing stream processing algorithms in a manner that naturally exposes their concurrency and makes the resulting programs readily implementable on highly parallel architectures. Dataflow programs are graph structured, with nodes representing computational kernels that process the data flowing over the edges. There are two major families of languages for t
A computer-implemented method of caching data in a managed runtime computing environment can include loading source data and comparing content of the source data with at least one of a plurality of cache entries. Each cache entry can include a representation of previously received source data and a transformation of the previously received source data. A transformation for the source data from a c
Since the invention of the first car available to masses, the 1908 Ford Model T, technology has advanced towards making car travel safer for occupants and bystanders. In recent years, wireless communication has been introduced in the vehicular industry as a means to avoid accidents and save lives.Wireless communication may sometimes be challenging due to obstacles in the physical world that intera
Channel modeling studies in vehicle-to-vehicle (V2V) communications have shown that larger road users act as blocking objects for the communication of surrounding vehicles, dramatically altering the statistical properties of the wireless channel. Without a strong line-of-sight component, packet delivery depends on other propagation mechanisms that are statistically more likely to add destructively
Partially Premixed Combustion (PPC) is a promising combustion concept with high thermodynamic efficiency and low emission level, and also with minimal modification of standard engine hardware. To use PPC in a production oriented engine, the optimal intake charge conditions for PPC should be included in the analysis. The experiments in this paper investigated and confirmed that the optimal intake c
Domain-continuous visibility determination algorithms have proved to be very efficient at reducing noise otherwise prevalent in stochastic sampling. Even though they come with an increased overhead in terms of geometrical tests and visibility information management, their analytical nature provides such a rich integral that the pay-off is often worth it. This paper presents a time-continuous, prim
The ignition delay is an important quantity in low temperature combustion concepts where a prolonged ignition delay gives an enhanced fuel-air mixing process, favorable for decreased particulate and NOx emission levels. This article investigates three different low-order physics-based correlation models and their ability to predict the ignition delay for the purpose of model-based controller desig
Precise air-path control of heavy-duty diesel engines contributes to emission regulation and high engine efficiency. The air path with VGT and EGR system is highly nonlinear with non-minimum-phase-system properties. The authors present a nonlinear control design - Receding Horizon Sliding Control (RHSC) to solve the tracking problem of the air-path. This control method handles the nonlinear dynami
Advanced combustion concepts like partially premixed combustion (PPC) are sensitive to inlet gas conditions especially inlet temperature. To estimate the combustion parameters like ignition delay on a cycle-to-cycle basis, both complementary filter and extended Kalman filter were designed to estimate the inlet temperature, and the ignition delay was calculated with properly estimated temperature.
Student engagement is an important factor when it comes to the learning process. Students who do not feel engaged in their studies risk surface learning, are more likely to fail their exams and might even drop out of their education. The teaching community has tried different methods in order to increase student engagement. One of them is the Contributing Student Pedagogy (CSP), where students con
Tidigare forskning belyser den ökade användningen av big data och dess påverkan på konsumenters integritet, attityder och inställningar, vilket generellt visar en negativ syn på insamling av personlig data. Denna studie undersöker hur konsumenter agerar och påverkas av datainsamling och cookies i riktad marknadsföring. Genom en kvantitativ metod har konsumenters attityder, val och beteende analyse

This thesis work is an academic study investigating how to transform and re-purpose the abandoned hydroelectric powerplant, Hästbergadammen. The powerplant has been abandoned since the dam collapsed in 2010, and the case of rebuilding it has been in the Land and Environment Court since 2016. The thesis proposes a new purpose for the site. It suggests giving back a public monumental place where t

UBER är ett globalt företag som växer snabbt. UBER har skapat en applikation som gör det möjligt att, via applikationen, beställa en taxiresa från en person som kör sin egen bil. Enligt UBER är det dock inget transportföretag, utan istället en teknologiplattform. Detta nya fenomen, där företag möjliggör tillgång till andra personers ägodelar, kallas för delningsekonomi. För att bli en UBER-förare UBER is a worldwide company growing rapidly. It has invented an application that makes it possible to request a ride from a driver which drives their own car. According to UBER, it is not a transport company but instead a technology platform. Moreover, this new phenomenon, whereby companies are enabling access for consumers to property owned by other consumers, is called sharing economy. In order
