Customer service plays an important role for the competitive strength in the market place. Customer service is however also a concern on the supply side of the company in the sense that assessing, selecting and developing suppliers to improve their customer service can make them contributing to the competitiveness of the company. It is from the latter perspective that this research has been carrie

Popular Abstract in Swedish En europeisk köpoption ger innehavaren rätten, men inte skyldigheten, att köpa en underliggande tillgång till ett visst pris, lösenpriset, vid ett bestämt datum, lösendagen. En europeisk säljoption definieras på motsvarande sätt: den ger innehavaren rätten, men inte skyldigheten att sälja den underliggande tillgången. En teori för hur denna typ av finansiella kontrakt sThis thesis consists of three chapters devoted to both empirical and theoretical aspects of option pricing. The first chapter investigates the market for European options on the Swedish OMX index using daily data for the period 1993-2000. The assumption of constant volatility of the returns underlying the Black and Scholes option pricing formula is assessed by extracting the volatilities implied

Informetric/bibliometric analyses have to a large extent been relying on an assumption that research is essentially cumulative in its nature, which is not the least visible in the rational for using citation analyses to assess quality of research. However, when reviewing both the theoretical literature on how research is organized and studies analyzing the structures of research fields through inf

The advent of Java and similar languages on the real-time system scene necessitates the development of efficient strategies for scheduling the work of a garbage collector in a non-intrusive way. We propose a scheduling strategy, time-triggered garbage collection, based on assigning the collector a deadline for when it must complete its current cycle. We show that a time-triggered CC with fixed dea

Abstract in UndeterminedThis article presents an integrated environment for application scheduling, binding and routing used for the run-time reconfigurable, operator based, ROMA multimedia architecture. The environment is very flexible and after a minor modification can support other reconfigurable architectures. Currently, it supports the architecture model composed of a bank of single (double)

Digital technology plays an important role in our work places, and much time is spent in the virtual environments that technol-ogy provides. However, today’s digital work environments are often cumbersome and hard to use, and contribute to stress and ill-health with subsequent cost to the individual, to their employ-ers and to society. Our long-term aim is to facilitate the develop-ment of IT syst

Mellan 16 februari och 22 mars 2017 genomfördes 24 mätningar av finfraktionen (PM2.5) och grovfraktionen (PM10 – PM2.5) av grundämnen i luftburna partiklar på mätstationerna i Stadshuset och Lundåkrahamnen i Landskrona. Detta gjordes som ett led i att kontrollera luftkvaliten i Landskrona stad, särskilt med tanke på industrierna i Landskrona, som tidigare har givit höga halter av framförallt metal

We have studied a selection of factors influencing the damage of DNA in nanochannels during fluorescence imaging. For cutting and nicking of DNA we show that the DNA is shortened during imaging. To avoid photodamage over the course of several hours of a typical experiment, we demonstrate the importance of an oxygen free gas to propel the buffer solution through the device. Finally, by varying the

We have developed a microfluidic chip for isolation of circulating tumor cells (CTCs) in blood based on microchannel acoustophoresis. Ultrasound radiation forces are used to separate cancer cells from blood cells in a continuous flow format. Separation was dramatically improved after incorporation of a 2-dimensional acoustic pre-alignment of the cells before entering the acoustophoresis separation

De första levande organismerna uppstod på jorden när den funnits i 1,5 miljarder år. Under de följande tre miljarder åren bildades livet på jorden, och existerade i harmoni, med gravitation, kosmisk-strålning, elektriska och magnetiska fält och dess cyklisk-hemlighetsfulla variationer medan exponeringen från den naturlga mikrovågstrålningen var endast i storleksordningen 210-15 W/kg. Det var i deOur team of the clinical researchers in Lund, Sweden, found that electromagnetic radiation, such as those used in mobile communications, even at shallow power values, cause users’ blood albumin to leak through the blood-brain barrier “BBB” into the brain tissue. The BBB is supposed to protect the brain against unwanted and toxic molecules potentially present in the blood, to transfer to the brain

The PET-CT imaging modality is based on positron emission tomography combined with computed tomography. Before a PET-CT examination, a radioactive tracer (also called a radiopharmaceutical) is intravenously injected into the patient. PET technology images the distribution of this tracer element by detecting the decay. In recent years, PET technology has been developed and improved in hardware and

Tiden är knapp att nå uppsatta klimatmål. För att nå dit krävs kraftfulla åtgärder och styrning. Det står även klart att vi inte når ett hållbart transportsystem med bara någrafå åtgärder – det krävs att en mängd olika åtgärder och styrmedel kombineras och införs. Utöver ökad energieffektivisering, byte av drivmedel och ökade transportkostnader krävs även åtgärder och styrmedel för ett mer transpo

We present a new experimental method for the measurement of the compressibility of cells by analysis of free flow acoustophoresis separation data.

We report a new method to select the optimal actuation frequencies in bulk acoustophoresis devices, by means of differential impedance spectrum analysis measured via the actuating piezoelectric transducer (piezo). The impedance spectra is rich of large spurious resonance peaks originating from bulk resonances not related to the channel resonance, Fig. 1a, why direct measurement of the piezo impeda

Inom besöksnäringen är delningsekonomins utbredning särskilt tydlig och inom denna industri återfinns en rad företag såsom Airbnb, Vayable, Getmyboat, OffWeFly, EatWith, Uber, Fodora och Travelbuddy. Airbnb, som förmedlar uthyrning av privatpersoners bostäder som en sorts hotellrum, är kanske det mest välkända företaget. Typiskt för delningsekonomin i tjänstesektorn är digitala plattformar som sam

The “neurotrophic hypothesis of depression” posits that low levels of brain-derived neurotrophic factor (BDNF) are associated with Major Depressive Disorder (MDD). Low levels of BDNF have also been found in individuals with suicide attempts, in MDD or other disorders, suggesting that low BDNF may also be associated with suicidality. We assessed serum BDNF in 68 physically healthy and unmedicated (

Many ships today rely on Global Navigation Satellite Systems (GNSS), for their navigation, where GPS (Global Positioning System) is the most well-known. Unfortunately, the GNSS systems make the ships dependent on external systems, which can be malfunctioning, be jammed or be spoofed. There are today some proposed techniques where, e.g., bottom depth measurements are compared with known maps using

This work presents an acoustofluidic chip capable of separating cells form their corresponding secretome for subsequent MALDI-MS analysis, which can be used amongst many other applications for directed evolution.

Objective: Antimuscarinic treatment in fasted mice and rats causes clonic convulsion soon after food intake. This study was designed to evaluate the electrophysiological markers of these convulsions and fasting in electrocorticograms in rats. Methods: Male Wistar albino rats were stereotaxically implanted with 10 cortical electrodes, and baseline electroencephalogram recordings were taken for 10 m
