Design of Energy Saving Windows with High Transmission at 900 MHz and 1800 MHz

This paper focuses on the radio wave propagation through energy saving windows. These panes have a metallic shielding that keeps the heat inside the building during winter and outside during summer. Unfortunately, this covering also has an opaque behaviour at microwave frequencies. A design of energy saving window panes with high transmission at 900MHz and 1800MHz is presented. The high transmissi

A characterization of optimal base-stock levels for a multistage serial supply chain

In this article, we present a multistage model to optimize inventory control decisions under stochastic demand and continuous review. We first formulate the general problem for continuous stages and use a decomposition solution approach: since it is never optimal to let orders cross, the general problem can be broken into a set of single-unit subproblems that can be solved in a sequential fashion.

Boendes agerande under energikrisen 2022/2023

Bostads- och servicesektorn utgör 40 procent av Sveriges totala energianvändning. Endast småhus står för drygt 8 procent. Energin som används i småhus går i huvudsak till uppvärmning och varmvatten. 2020 var direktverkande el den vanligaste energikällan för uppvärmning av småhus (Energimyndigheten 2022). Elpriset har stigit kraftigt under det senaste året. Detta kan eventuellt ha påverkan på boendThe building and service sector consume 40 percent of Sweden’s total energy use. Which of only single-family houses are responsible for 8 percent. The energy used in single family houses mainly goes to heating and hot water. 2020 the most common energy source for heating these buildings was electricity (Energimyndigheten 2022). The energy prices have increased heavily during the last year. This ma

Luftflöde genom vädring i ett sidohängt fönster - Mätning och simulering

Enligt EUs senaste direktiv kan medlemsländernas befintliga byggnader behöva energieffektiviseras. Hittills har byggnaders energianvändning beräknats med normaliserade brukare, vilket avspeglat byggnadernas medelanvändande baserat på befintligt brukarbeteende. Förändringarna ställde krav på bättre underlag för brukarrelaterade indata, samt även på en metod för energiberäkningar av vädring. Därför The latest European Union directive pressures the member states to increase existing building energy efficiency. Calculations of building energy has in Sweden a dependency of normalized user behaviour data, which has reflected the average use based on existing data. Changes increase the demand for better background data on usage of dwellings, as well as a method for calculating the energy use due

Mannen i mitten. Ett spiondrama i svensk kallakrigskultur

Popular Abstract in Swedish Spionen var under kalla kriget en gäckande gestalt som i egenskap av sin synliga osynlighet blev en orienteringspunkt för vardagliga fantasier. Han – för denna det kalla krigets emblematiska figur var oftast en han – blev i flera avseenden just en samtidens mittpunkt i vilken en tudelad världsbild synliggjordes. Mannen i mitten handlar om Spionen i svensk kallakrigskultThe aim of this thesis is to contribute to a broadening of perspectives on Cold War Sweden. It is a study not primarily of the explicit political events or debates, but of the everyday cultural narratives of the era. During the long 1950s, Swedish Cold War imagination was largely characterised by a determination to maintain total security in the response to the threats that loomed on all sides, an

Ukrainian Language Policy: The Status of Russian in English Language Medium Ukrainian and Russian Newspapers and in the Linguistic Landscape of Four Regions

Following a long-standing sociolinguistic pursuit to investigate language policy through complex non-linear models that analyze historical, structural, political and social processes that produce, contextualize, circulate and negotiate particular ideologies, beliefs and myths about languages and their values through meaning-making activities, this master’s thesis aims to apply an interpretive appr

Dystopiernas seger : totalitarism som orienteringspunkt i efterkrigstidens svenska idédebatt

The purpose of this study is to dissect the process of ideological orientation in the public debate of postwar Sweden. Crucial to the study is the idea of a generic totalitarianism; a concept used both on a scholarly and a political level, focusing on the similarities between communism and Nazism, and the diverging guiding potential of this totalitarianism idea in different times and situations.

Formulation and Interpretation of Optimal Braking Patterns in Autonomous Lane-Keeping Maneuvers

The two perspectives of autonomous driving and new active safety in vehicles are complementary, and both hold promise to reduce the number of accidents and associated severe or fatal injuries. They both coincide in the recent interest in finding alternatives to traditional yaw-control systems that can utilize the full potential of the vehicle. By considering the control problem as that of lane-kee

Slip-Angle Feedback Control for Autonomous Safety-Critical Maneuvers At-the-Limit of Friction

From the basis of optimal control, a closed-loop controller for autonomous vehicle maneuvers at-the-limit of friction is developed.The controller exploits that the optimal solution tends to be close to the friction limit of the tires.This observation allows for simplifications that enable the use of a proportional feedback control in the control loop,which provides a smooth trajectory promising fo

Extreme leukoreduction of major histocompatibility complex class II positive B cells enhances allogeneic platelet immunity

In a murine model of platelet alloimmunization, we examined the definitive role that mononuclear cells (MC) have in modulating platelet immunity by using platelets from severe combined immunodeficient (SCID) mice. CB.17 (H-2(d)) SCID or BALB/c (H-2(d)) mouse platelets were transfused weekly into fully allogeneic CBA (H-2(k)) mice and antidonor antibodies measured by flow cytometry. MC levels in BA

Extraction of the specific shear viscosity of quark-gluon plasma from two-particle transverse momentum correlations

The specific shear viscosity, η/s, of the quark-gluon plasma formed in ultrarelativistic heavy-ion collisions at RHIC and LHC is estimated based on the progressive longitudinal broadening of transverse momentum two-particle correlators, G2, reported as a function of collision centrality by the STAR and ALICE experiments. Estimates are computed as a function of collision centrality using the Gavin

γ∗γ∗ →ηc (1S,2S) transition form factors for spacelike photons

We derive the light-front wave function (LFWF) representation of the γ∗γ∗→ηc(1S),ηc(2S) transition form factor F(Q12,Q22) for two virtual photons in the initial state. For the LFWF, we use different models obtained from the solution of the Schrödinger equation for a variety of cc̄ potentials. We compare our results to the BABAR experimental data for the ηc(1S) transition form factor, for one real

Growth selectivity control of InAs shells on crystal phase engineered GaAs nanowires

In this work we demonstrate a two-fold selectivity control of InAs shells grown on crystal phase and morphology engineered GaAs nanowire (NW) core templates. This selectivity occurs driven by differences in surface energies of the NW core facets. The occurrence of the different facets itself is controlled by either forming different crystal phases or additional tuning of the core NW morphology. Fi

Population fluctuations and synchrony of grassland butterflies in relation to species traits.

Population fluctuations and synchrony influence population persistence; species with larger fluctuations and more synchronised population fluctuations face higher extinction risks. Here, we analyse the effect of diet specialisation, mobility, length of the flight period, and distance to the northern edge of the species' distribution in relation to between-year population fluctuations and synchrony

Theory of baryon resonances at large N-c

At large number of colors, N-c quarks in baryons are in a mean field of definite space and flavor symmetry. We write down the general Lorentz and flavor structure of the mean field, and derive the Dirac equation for quarks in that field. The resulting baryon resonances exhibit a hierarchy of scales: the crude mass is O(N-c), the intrinsic quark excitations are O(1), and each intrinsic quark state

A new module for constrained multi-fragment geometry optimization in internal coordinates implemented in the MOLCAS package.

A parallel procedure for an effective optimization of relative position and orientation between two or more fragments has been implemented in the MOLCAS program package. By design, the procedure does not perturb the electronic structure of a system under the study. The original composite system is divided into frozen fragments and internal coordinates linking those fragments are the only optimized
