Most exporting firms in the world also import foreign inputs in production. Recent findings elucidate the importance of imports as a driver of firm productivity on the amount of goods exported. This study aims at investigating the correlation between imports and firm productivity, not the causality. It will add to previous research by shifting focus from import participation to import intensity an

To communicate reliably over noisy wireline or wireless channels, algorithms that add redundancy are used to help reconstruct the transmitted sequence at the receivers. Such error control coding algorithms are today used in all digital communication systems. Optimum decoding algorithms such as the Viterbi and BCJR have very good performances but often too high complexity. Therefore, less complex s

This work will first go through different definitions about what constitute a holding company. Thereafter the Swedish tax rules, relevant for the localisation of a holding company, will be examined. Subsequently different definitions will be discussed about what constitute a holding company. In that context the concept tax paradise will be discussed. In the next chapter those criterias will be dis

This chapter explores the processes of a typical logistics network for the management of reusable packaging for food products. While theimpacts associated with packaging waste in the food sector are well known, the adoption of reusable crates or handling systems for fooditems entails many logistics processes such as storage, transportation, and cleaning, whose impact needs to be quantified and assThis chapter explores the processes of a typical logistics network for the management of reusable packaging for food products.

Decarbonizing the energy-intensive and natural resource-based industries is possible but may sub-stantially increase the cost of production. Whether such cost increases will reduce economic welfare depends on how the downstream industries respond to the higher cost for intermediate goods. In this paper, we explore how downstream industries in the EU15 responded to upstream carbon technology shocks

Massive multiple-input multiple-output (MIMO) is expected to be a vital component in future 5G systems. As such, there is a need for new modeling in order to investigate the performance of massive MIMO not only at the physical layer but also higher up the networking stack. In this paper, we present general optimization models for massive MIMO, based on mixed-integer programming and compatible sets

Road haulage operations in general, and distribution in particular, are inefficient. Given the societal importance of road haulage and the low efficiency of the sector, road hauliers need to improve their operations and systematically tackle inefficiencies. However, the real causes of these inefficiencies, the “root causes”, have not been sufficiently examined in previous studies.

Background Self-management is the main concept constituting the foundation of follow-up care after heart transplantation. Self-efficacy is a foundation of self-management. Little is known about heart recipients’ experiences in relation toself-efficacy and self-management after heart transplantation. Aim The overall aim of this thesis was to explore uncertainty and self-efficacy as important aspect

Anorectal malformations (ARM) are a spectrum of congenital malformations, specifically defined by the absence of a normal anal opening. These conditions are treated surgically by posterior sagittal anorectoplasty and, in cases with perineal fistulas, perineal skin advancement is required to cover the tissue defect. Complications involving wound dehiscence are frequent, and may be due to stretching
