The COST 2100 channel model is a geometry-based stochastic channel model (GSCM) that can reproduce the stochastic properties of multi-link Multiple-Input Mulitple-Output (MIMO) channels over time, frequency and space. By contrast to other popular GSCMs, the COST 2100 approach is generic and flexible, making it suitable to model multi-user or distributed MIMO scenarios. In this paper a concise over
Recent years have seen an increasing attention given to wireless Personal Area Networks (PANs), which are typically networks with small transmitter-receiver (TX-RX) separation. The desire for high data rates has led to an interest in deploying multiple-input multiple-output (MIMO) transmission for such systems, but up until this date there exists, to the authors’ best knowledge, no MIMO channel mo
Regression testing is verifying that previously functioning software remains after a change. With the goal of finding a basis for further research in a joint industry-academia research project, we conducted a systematic review of empirical evaluations of regression test selection techniques. We identified 27 papers reporting 36 empirical studies, 21 experiments and 15 case studies. In total 28 tec
We consider weighted sequence spaces on N with increasing weights. Given a fixed integer k and a Hankel operator Gamma on such a space, we show that the kth singular vector generates an analytic function with precisely k zeroes in the unit disc, in analogy with the classical AAK-theory of Hardy spaces. We also provide information on the structure of the singular spectrum for Hankel operators, appl
Context: Coping with rapid requirements change is crucial for staying competitive in the software business. Frequently changing customer needs and fierce competition are typical drivers of rapid requirements evolution resulting in requirements obsolescence even before project completion. Objective: Although the obsolete requirements phenomenon and the implications of not addressing them are known,
Model order selection is an important element in system identification. It is well known that common model order selection methods such as Akaike’s information criterion (AIC) and Bayesian’s information criterion (BIC) neglect relevant information that is available in models of order different from the one chosen. In this paper the model order selection problem for receivers similar to those found
We present a 2nd-order 4-bit continuous-time (CT) delta-sigma modulator (DSM) employing a 2nd-order loop filter with a single operational amplifier. This choice strongly reduces the power consumption, since operational amplifiers are the most power hungry blocks in the DSM. The DSM has been implemented in a 65 nm CMOS process, where it occupies an area of . It achieves an SNDR of 64 dB over a 500
Abstract in UndeterminedFaster-than-Nyquist (FTN) signaling is a method of improving bandwidth efficiency by transmitting information beyond Nyquist's orthogonality limit for interference free transmission. Previously have theoretically established that FTN can provide improved bandwidth efficiency. However, this comes at the cost of higher decoding complexity at the receiver. Our work has evaluat
Building in a manner that minimizes environmental impact has become a major part of the construction industry. Despite increased knowledge in this area the development is moving slowly. The purpose of this thesis is to give the reader an idea of the approach to green construction of civil engineering. The definition of a green tender is defined by the people who have been interviewed. The question
The historical development of responsibility for wars and aggressive acts has seen a shift of focus during the last century. Where the attention was previously focused on the unlawfulness of a State act (the Act of Aggression), the attention is now on the involvement and responsibility of individuals. The topic of this thesis is to follow the development of the possibility to hold those behind Sta
Since the 1980s, financial deregulation and welfare cuts have driven an economic risk shift, requiring individuals to take greater financial responsibility through private savings in stocks and mutual funds. An unexplored aspect of this “financialization of everyday life” is the personal finance advice provided by experts employed by banks and other market-oriented actors. This study examines fina

The Caroline Case with its principles of necessity, proportionality and immediacy is alleged to be part of customary international law consider anticipatory self-defence, but a closer examination views that it can not be, mostly because of States are not convinced that it is the correct behaviour. Even if Article 51 of the UN Charter has been expanded to include acts of terrorism as armed attacks,
Sammanfattning Detta examensarbete kommer att handla om relationen mellan den svenska åklagarmyndigheten och den europeiska åklagarmyndigheten med rättssäkerhet/effektivitet som examensarbetets teoretiska verktyg. En mycket viktig sak som måste påpekas är att den europeiska åklagarmyndigheten ännu ej finns, men EU är mycket angeläget om att inrätta myndigheten. Å ena sidan vill EU inrätta myndighe
The purpose of this study is to advance the theoretical knowledge of internationalisation of small and medium-sized firms from an individual perspective. In particular, the research takes a cognitive approach in understanding how experiential knowledge shapes entrepreneurs’ uncertainty perception and thus their willingness to recognise and act upon export opportunities. Six in-depth, semi-structur
Det är vanligt att privatpersoner köper fordon på avbetalning med ett återtagande- och/ äganderättsförbehåll. I avbetalningskontraktet skrivs vanligtvis in att köparen ska teckna en motorfordonsförsäkring hos ett försäkringsbolag. Motsvarande gäller vid leasing av ett fordon, där det vanligtvis är leasingtagaren som ska teckna en motorfordonsförsäkring. Det finns några krav som försäkringstagaren It is common for individuals purchasing vehicles via hire purchase in a readmission and / retention of title. The installment contract is usually written so that the buyer must take out motor insurance with an insurance company. The same applies to the leasing of a vehicle, where it is the lessee who usually must take out motor insurance. There are requirement thus ensuring that the policyholder i
Through Robert A. Dahl’s criteria of democracy I am in this bachelor’s thesis pursuing a normative analysis. I am using the criteria as values that are being examined through a normative given this value- method. The case I am examining is the implementation of road tolls in Gothenburg. The material analyzed, in order to see if the values are considered, are articles collected from local newspaper
The purpose of this study has been to analyze the social services' information texts to see what pattern emerge from these texts, and how this relates to power. Users of social services in Sweden receive a wide array of information texts from the social welfare offices. Despite several efforts from the Swedish government to make the language in these text more simple they still come across as
