This demonstration presents a highperformance syntactic and semantic dependency parser. The system consists of a pipeline of modules that carry out the tokenization, lemmatization, part-of-speech tagging, dependency parsing, and semantic role labeling of a sentence. The system’s two main components draw on improved versions of a state-of-the-art dependency parser (Bohnet, 2009) and semantic role l
It has been proposed that six co-located antennas, namely three electric and three magnetic dipoles, can offer up to a six-fold capacity increase in wireless channels, relative to that of single antennas. In other words, six degrees of freedom (DOFs) can be supported by co-located six-port transmit and receive antenna arrays. However, due to the complexity in designing and measuring such a six-por
This paper presents a 3rd-order, 3-bit continuous time (CT) Delta-Sigma modulator for an LTE radio receiver. By adopting a return-to-zero (RZ) pulse in the innermost DAC, the modulator shows a reduced sensitivity to loop-delay variations, and the additional loop delay compensation usually needed in CT modulators can be omitted. The modulator has been implemented in a 65nm CMOS process, where it oc
Popular Abstract in Swedish Vår egen tid kännetecknas av ett mycket stort intresse för Förintelsen, det vill säga nazisternas folkmord på Europas judar. Denna bok försöker skissera några viktiga aspekter av den kulturella förståelsen av Förintelsen, genom att studera hur den avbildats i visuell kultur. Med "visuell kultur" förstås ett brett spektrum av kulturella uttryck, från dokumentär- och presThis thesis examines the representation in visual culture of the Holocaust, the Nazi genocide of European Jewry. It is divided into three main parts, each one focusing on a particular aspect of Holocaust representation. Part 1, "Meaning" (chapter 1-3), begins by considering the important role played by documentary photographs from the concentration camps for the public knowledge and conception of
With increasing usage of the Internet, energy consumption of network equipment has become a crucial challenge from both an economic and an environmental point of view. This paper combines users’ behavior of accessing the network with energy saving algorithms for energy-aware network equipment, and investigates potential energy savings in the access network. The study is based on a set of traffic d
Internet traffic from a fibre based residential access network is investigated concerning traffic volumes and link load. Also the cost of the services is analyzed. We show that 1 Mbps accesses subscribers maintain high loads, and that the price they pay per GB used is five times higher than the one paid by 100 Mbps access subscribers.
This paper describes an attempt to provide more intelligence to industrial robotics and automation systems. We develop an architecture to integrate disparate knowledge representations used in different places in robotics and automation. This knowledge integration framework, a possibly distributed entity, abstracts the components used in design or production as data sources, and provides a uniform
Excitation of the chassis enables single-antenna terminals to achieve good bandwidth and radiation performance, due to the entire chassis being utilized as the main radiator. In contrast, the same chassis excitation phenomenon complicates the design of multiple antennas for MIMO applications, since the same characteristic mode of the chassis may be effectively excited by more than one antenna, lea
Electromagnetic vector spherical waves have been used recently to model antenna-channel interaction and the available degrees of freedom in MIMO systems. However, there are no previous accounts of a method to estimate spherical wave coefficients from channel measurements. One approach for this, using a 3D positioner, is presented and analyzed in this letter. Measurement results are presented and d
Base station (BS) cooperative transmission is a promising technique to improve spectral efficiency of cellular systems, using which the channels become asymmetric in average gain. In this paper, we study the impact of the asymmetric channel gains on the performance of coherent cooperative transmission systems, when minimum mean square error (MMSE) and least square (LS) channel estimators are appli
The Theory of Characteristic Modes (TCM) has been applied to design high-performance MIMO antennas for mobile terminals. However, existing studies focus on free-space (FS) performance, which is mostly irrelevant in real usage. This paper investigates the performances of two TCM-based MIMO terminal antenna designs in 7 realistic user scenarios for frequencies below 1 GHz. Full-wave simulation resul
This essay deals with the so-called Islamic State´s propaganda paper Dabiq and how the use of history in it helps create historically based depictions of the Islamic State´s enemies. I have analysed the first four issues of Dabiq from 2014 and used Jakob Dahlbacka´s definition of religious use of history and prophetic use of history as an analytical frame. I have analysed both text and images in D
Formulering av läkemedel kräver att man tar tag i ett flertal problem för att optimera effektiviteten. All former av formuleringar har sina egna utmaningar som vetenskapsmän och företag försöker lösa. Till exempel, leverns nedbrytning av läkemedlet, det så kallade första-passage-metabolismen, minskar koncentrationen av den aktiva substansen och, i värsta fall, förändrar den till en giftig form. DeThe aim of this master thesis is to provide an indication of the suitability, or otherwise usage, of spray-drying for production of powder aimed for inhalation formulation and comparing the characteristics of the product, with and without lipids. Lipids have a proven effect of delaying release of active drug substances in the cardiovascular system and pulmonary systemic delivery has a number of ad
Finansmarknaden genomgick stora förändringar innan 2000-talet och placeringsrådgivning kom att spela en allt viktigare roll. Tidigare hade det inte funnits lagstiftning på området, vilket man nu införde. Först kom Lag (2003:862) om finansiell rådgivning till konsumenter (FRL), därefter utfärdades ett EG-direktiv. Direktivet införlivades i svensk rätt genom Lag (2007:528) om värdepappersmarknaden (The Financial Market went through significant changes before the 2000’s and investments advisory played an increasingly important role. Earlier there had not been any legislation on the subject which there is now. The first legislation was the act of financial advisory and after that the Markets in Financial Instruments Directive, MiFID came from the EU. MiFID was implemented into Swedish law thro
Människans roll inom IS kan ofta falla till glömska inom organisationer som besitter en hög teknisk medvetenhet. Då utvecklingen av tekniska lösningar sker i explosionsartad takt blir möjligheten för användaren att hänga med mindre för varje ny funktion. Säkerhetsmedveten-het är därmed en fråga som bör diskuteras och göras mer aktuell inom organisationer idag då litteratur påvisar att det inte fin

Method: A study in the form of a quantitative method based on Tobias E. Carlisle formula The Acquirer’s Multiple with data extracted on a monthly basis from Thompson Reuters Datastream. Theory
Det är en grundidé i aktiebolagslagen att bolagsformen i stor utsträckning skall utgöra en riskbegränsad form av företagande. Det finns dock situationer där denna idé frångås och fysiska personer blir ansvariga för bolagets skulder. Uppsatsen skall utreda sådana situationer i anslutning till ABL:s regler om kritisk kapitalbrist. Reglerna riktar till stor del in sig på styrelsen och dennes agerandeIt’s one of the basic ideas Swedish Companies Act (SCA) that limited liability company is supposed to be a risk-limited form of business for owners, board members and other company officials. There are however situations when this idea is put aside in favour for other interests and board members can be personally responsible for the company’s debts. This essay will investigate such situations in c
