We consider a networked control system where a linear time-invariant (LTI) plant, subject to a stochastic disturbance, is controlled over a communication channel with colored noise and a signal-to-noise ratio (SNR) constraint. The controller is based on output feedback and consists of an encoder that measures the plant output and transmits over the channel, and a decoder that receives the channel

The physical bounds for antennas above a ground plane is analyzed in this paper. Optimal antenna G/Q ratio and Q factor are calculated using convex optimization from stored electric and magnetic energy matrices, obtained from a method of moments solver. Physical bounds for a patch antenna with different heights above a ground plane are investigated. Results are verified using commercially availabl

Context: The Gaia project will determine positions, proper motions, and parallaxes for more than one billion stars in our Galaxy. It is known that Gaia's two telescopes are affected by a small but significant variation of the basic angle between them. Unless this variation is taken into account during data processing, e.g. using on-board metrology, it causes systematic errors in the astrometric pa

Varying degrees of collaboration and consultation in the area of child and family welfare in the public sector has grown rapidly since the 1980s, especially concerning children at risk. Collaboration is understood to provide a more holistic view of the individual's needs, lead to better care and treatment as well as increase knowledge in general. Collaboration in that sense constitute a flexible a

We show that recent robust adaptive beamformers, based on reconstructing either the noise-plus-interference or the data covariance matrices, are sensitive to the noise-plus- interference structure and degrade in the typical case when interferer steering vector mismatch exists, often performing much worse than common diagonally loaded sample covariance matrix based approaches, even when signal-of-i

Popular Abstract in Swedish Att kunna resa och transportera gods är en del av människors vardag i dagens samhälle. De flesta av dessa transportmedel använder förbränningsmotorer på grund av dess flexibilitet, låg global kostnad och lång körsträcka. Utsläpp i olika former är en oönskad biprodukt av förbränningsmotorer som är skadlig både för människor och för miljön. Diesel motorer är idag bland deInternal combustion engines have been an important technological field for more than a century. It has had an important impact on society through improved transportation and industrial applications. However, concerns about environmental effects of exhaust gases and utilization of oil resources have pushed development of combustion engines towards cleaner combustion and higher efficiencies. The d

The increasing demand on improved reception and high data throughput brings into focus the design of compact multiband antenna terminals with diversity reception capability. In particular, the influence of user on diversity performance is of current interest. In this paper, the diversity performance of compact tri-band antennas (WCDMA850, WCDMA1800 and UMTS 2100) for mobile handsets is evaluated i

The evolution of media has gained much headway this past decade and has outpaced many countries’ ability to keep up. It has even left linguistic gaps in the Arabic language, and has sparked one Jordanian, Muhammed Jaradat, to create new Arabic terminology to fill this social media language gap. As internet proliferation increases in Arab countries and access to higher connection speeds becomes ava
