Purpose: To investigate how consumers understand free services on the Internet. Theories: The research is primarily based upon theories of gift giving. Methodology and analysis: The Internet is not a tangible marketplace and in order to understand the value of the free services online, we used consumers' behavioral accounts to explain how they perceive the free services that are common online.
Families of generalized spatially-coupled low-density parity-check (GSC-LDPC) code ensembles can be formed by terminating protograph-based generalized LDPC convolutional (GLDPCC) codes. It has previously been shown that ensembles of GSC-LDPC codes constructed from a protograph have better iterative decoding thresholds than their block code counterparts, and that, for large termination lengths, the
Time constants in spiking neural networks (SNNs) are crucial for determining performance. While prior work shows that learning time constants can improve accuracy, it typically assumes near-optimal initial values and rarely examines recovery from poor initializations. We systematically study how membrane and synaptic time constants affect SNN performance using multiple training strategies. Our res
The Learning with Errors (LWE) problem receives much attention in cryptography, mainly due to its fundamental significance in post-quantum cryptography. Among its solving algorithms, the Blum-Kalai-Wasserman (BKW) algorithm, originally proposed for solving the Learning Parity with Noise (LPN) problem, performs well, especially for certain parameter settings with cryptographic importance. The BKW a
We study the well-posedness of a class of dynamical flow network systems describing the dynamical mass balance among a finite number of cells exchanging flow of traffic between themselves and with the external environment. Dynamical systems in the considered class are described as differential inclusions whereby the routing matrix is constant and the outflow from each cell in the network is limite
In 1981 appeared my first published paper, with the title, “A plea for integral linguistics”,which summarized the epistemological stance of my 1978 doctoral dissertation. In a lecture given in Bucharest, published only in 2004, Coseriu said that he very belatedly, in 1981, applied the term “integral linguistics” to his conception of linguistics. There is an enormous difference between a young scho
Outbound foreign direct investments by developing economies has become an important subject in international business. However, much of the research has attempted to model firms entering foreign markets from emerging economies using the same models developed for advanced economies, which limits what can be inferred. This gap suggests that other approaches are needed. One such approach is analyzing
Too dangerous to forget – a semiotic and contextual study of the memorial Romanoparken – Sång om en plats This essay examines the memorial Romanoparken – Sång om en plats (2020), which embodies Roma memories. However, there are risks with memorials when they take the material form of a monument that they are seen as completed actions and the completion can lead to distancing oneself from the
This study investigates how the debt levels of firms belonging to the Nordic market change over time and what determines these changes. We find that contemporaneous changes in leverage are mainly determined by profitability, market timing, leverage deficits (deviations from target leverage) and changes in targets. We find two factors whose effects persist for at least ten years, namely profitabili
In this paper we provide an analytical solution to an H2 optimal control problem, that applies whenever the process corresponds to a uniformly damped network of masses and springs. The solution covers both stable and unstable systems, and illustrates analytically how damping affects the levels of achievable performance. Furthermore, the resulting optimal controllers can be synthesised using passiv

In this study, global wave climates for present and future climates are simulated by the WAM model, based on wind climate data from the JMA/MRI-AGCM3.2 climate change projection. This study is based on two 6-hourly wind data sets, covering two periods of 1979-2003 (present climate) and 2075-2099 (future climate). These wind data are used to run the WAM model for generating output of wave character
Moisture is decisive for a large number of reaction, binding and transport processes in concrete affecting the durability, shrinkage and performance in various environments. Consequently, the role of moisture must be assessed and quantified in a diagnosis of concrete degradation by moisture measurements and a survey of environmental actions. The paper gives an over-view of the role of moisture in
Popular Abstract in Swedish Vi kan inte avslöja innehållet i våra tankar direkt, så hur kan vi närma oss de underliggande kognitiva processerna? Om vi vill lära oss mer om vad som försiggår i vår tankevärld, måste vi göra det indirekt, med hjälp av tankarnas yttre manifestationer. Det finns olika metoder som man kan ta till sin hjälp. I min avhandling kopplar jag ihop två ämnesområden, lingvistik In this thesis, I connect two disciplines, linguistics and vision research, and combine two methods, spoken language protocols and eye movement protocols, in order to cast light on the underlying cognitive processes. In a series of studies, I investigate the processual aspects of picture viewing and picture description. On the one hand, eye movements reflect human thought processes. It is easy to
We study the self-adjoint Pauli operators that can be realized as the square of a self-adjoint Dirac operator and correspond to a magnetic field consisting of a finite number of Aharonov–Bohm solenoids and a regular part, and prove an Aharonov–Casher type formula for the number of zero-modes for these operators. We also see that essentially only one of the Pauli operators are spin-flip invariant,
The aim of this article is to reflect on the evolution of total quality management (TQM) as the most widespread quality management approach during the last 25 years. However, during the first 10 years of the new millennium, the term TQM seems to have lost its attractiveness in Western parts of the world and instead new terms such as Business Excellence, Organisational Excellence, Six Sigma, and Le
