This paper presents three mathematical formulations for designing robust two-layer networks carrying elastic traffic. The formulations differ by the way flow reconfiguration is performed in the case of link failures. An iterative algorithm to solve the problems is given and an extensive numerical study is provided comparing the effectiveness of the three reconfiguration approaches. The formulation

In this paper, heat and mass balances of the intercooler in a 100 kW Proton Exchange Membrane Fuel Cell (PEMFC) system are analyzed by employing a commercial software IPSEpro. The compressor, ambient temperature, the humidification method and the PEMFCs cathode operating temperature were considered as the parameters influencing the heat and mass balances in the intercooler. Parametric studies of t

Risk management is an important process for public service organizations to maintain a high quality of service. However, many organizations are not satisfied with the result from risk handling. This paper proposes changes to a risk management model by integrating service level agreements into it. This makes responsibilities more clear to all parties involved in risk management. This paper also int

Popular Abstract in English Bolivia, as with other Latin American countries, is considered to be in an epidemiological transition due to the continued persistence of infectious diseases, and nutritional deficiencies related to poverty and food insecurity, together with an increase in chronic non-communicable diseases mainly related to lifestyle factors. The work presented in this thesis was focuseThe synergistic relation between nutritional deficiency and infection may have negative effects on the immune system, making individuals more vulnerable to infection. Zinc can affect the resistance to infections by modulating cytokine release, and by acting as a cofactor of thymulin, which induces the differentiation of immature T lymphocytes. To investigate the modulation of the immune response b

Global competition forces companies to constantly increase the efficiency in their production systems. One important factor affecting the production performance is the inbound materials handling system. When designing or relocating a manufacturing system, the cost of the material handling system is one of many things to take into consideration. In connection with on-going research a comprehensive

The paper deals with durability of Self-Compacting Concrete with limestone filler during Thaumasite Sulphate Attack. For this purpose six concrete with varying amounts of limestone filler, particle size of limestone filler, pressure height during casting and mixing order were studied. One normal concrete (without limestone filler) with vibrator compaction was studied in parallel. In the ongoing ex

This book discusses the concept of a queer feminism, a possible negotiation between queer theory and feminism.

Popular Abstract in Swedish I solens inre finns ett område där het, joniserad och mycket turbulent gas alstrar stora elektriska strömmar. Dessa strömmar genererar i sin tur ett starkt magnetfält som stiger upp till solens yta, fotosfären. I fotosfären uppstår en del intressanta magnetiska fenomen som till exempel solfläckar. Solfläckar är relativt svala områden som skapas då magnetfält hindrar denA solar magnetic field is continuously being created in the solar interior. As the field evolves outward through the solar atmosphere and into the enveloping heliosphere, it causes effects on a wide range of temporal and spatial scales. By studying and measuring these magnetic effects we gain extensive knowledge about solar magnetism and it also allows us to model and predict how solar activity is

It is contended in this thesis that the introduction of a legal regime with a rateless structure, subject only to market forces and a rebuttable statutory presumption as to where the rate line of conscience should be drawn, can provide a solution if the rate charged by pawnbrokers is to be regulated. The thesis also shows that a uniform pawn ticket issued as a negotiable document of title, and tra

Exoplanets have been observed at many stages of their host star's life, including the main-sequence (MS), subgiant and red giant branch stages. Also, polluted white dwarfs (WDs) likely represent dynamically active systems at late times. Here, we perform three-body simulations which include realistic post-MS stellar mass-loss and span the entire lifetime of exosystems with two massive planets, from
