We jointly optimize Discontinuous Reception (DRX) cycle length and LTE scheduling to minimize mobile devices' energy usage for video delivery, utilising the now well-established potential to predict future channel conditions in cellular networks. Employing in-network caching, we set a strict buffer constraint which provides zero buffer underflow to improve Quality of Experience. Our study provides
From experience, it has been well known that the performance of IEEE 802.11 wireless local area networks significantly drops in dense settings, largely driven by poor capacity of the medium access control (MAC) layer. The current 802.11 MAC mechanism utilizes a contention window (CW) for random access, and the CW size is dictated to take discrete values from a bounded finite set. In this paper, wi
User Generated Content (UGC) is projected to make up a significant part of the total Internet traffic in the future. As such, it will significantly contribute to the total cost for Internet traffic worldwide. Arguably, UGC is a suitable content type for which the Internet Service Providers (ISPs) can take initiative and enter the content delivery market. However, despite its significance, UGC cont
When load balancing data centres with all serversactive to serve jobs, the result can be excessive energy usage. Onthe other hand, using dynamic server provisioning, the numberof servers that serve requests can be reduced by turning off idleservers and thereby save energy. However, such a scheme, usuallyincreases the risk of instability of server queues. In this work,we analyze the trade-off betwe
BACKGROUND: Tumor development requires angiogenesis, and antiangiogenesis has been introduced in the treatment of cancer patients; however, how the cardiovascular phenotype correlates with cancer risk remains ill-defined. Here, we hypothesized that vasoactive peptides previously implicated in angiogenesis regulation predict long-term cancer risk.METHODS: We measured midregional proatrial natriuret
OBJECTIVE: To assess the reliability of knee extensor and flexor muscle strength measurements in persons with late effects of polio. DESIGN: A test-retest reliability study. SUBJECTS: Thirty men and women (mean age 63 (standard deviation 6.4) years) with verified late effects of polio. METHODS: Knee extensor and flexor muscle strength in both lower limbs were measured twice 7 days apart using a Bi

Mixed-phase clouds contain both supercooled cloud liquid and ice crystals. In principle, precipitation may be initiated either by the liquid phase or by the ice phase. Ice crystals may grow by vapor diffusion to become snow ("ice crystal process"), forming "cold"precipitation. Equally, cloud droplets, when large enough, coalesce to form "warm"precipitation by the "warm rain process."Warm rain coul
In Part I, an electrification scheme was described and a simulation of an observed cold-based storm from the U.S. Great Plains was validated with electrical observations. Most charge in the storm was separated by rebounding collisions of secondary ice originating from prior graupel-snow collisions. In this Part II, sensitivity tests are performed with the control simulation (Part I) and influences
Lunds universitet har på uppdrag av Naturvårdsverket under 2021–2022 utvärderat metodik för nationell pollinatörsövervakning. Metodiken bygger på rapporten ”Proposal for an EU pollinator monitoring scheme” som tagits fram av en expertgrupp inom EU och ska ge underlag för uppföljning av pollinatörer på nationell nivå med ett främsta fokus på landskapet utanför områden som omfattas av EU:s gemensamm
The steadily increasing Internet of Things (IoT) devices are vulnerable to be used as bots to launch distributed-denial-of-service (DDoS) attacks. In this paper, we present X-Pro, a distributed XDP proxy to counteract DDoS attacks. We propose a source-based defense mechanism where proxies located between the IoT devices and the victim performs flow policing on all IoT traffic from a single adminis
The microphysical quasi-equilibrium in an ascending adiabatic parcel is elucidated by an analytical theory in 0D with drastic simplifications. The theory predicts how in-cloud activation is most likely to be triggered by the onset of precipitation during sufficient ascent, with the ascent only needing to approach almost twice the cloud-base updraft speed aloft. The precipitation and cloud condensa
Det har visat sig att fysisk aktivitet minskar risken för en rad olika sjukdomar. Studien syftade till att undersöka fysisk aktivitet i olika kontexter och på olika nivåer för att bidra med ny kunskap om eventuella hälsofördelar med fysisk aktivitet. Då det är betydelsefullt för organisationens effektivitet och produktivitet att de anställda mår bra är det också viktigt att organisationen arbetar Physical activity has been shown to reduce the risk of several illnesses. The study aimed to investigate physical activity in different contexts and on different levels to contribute with new knowledge about possible health benefits linked to physical activity. Since the health of the employees is crucial for the organization’s efficiency and productivity it is important that organizations promote
Svenska elitidrottares mentala träningsvanor undersöktes genom en webbaserad enkätundersökning som besvarades av 47 aktiva idrottare (28 män, 19 kvinnor, ålder 16-37, M=25) inom fotboll, friidrott, handboll, ishockey och tennis. Studien visade att svenska elitidrottare i genomsnitt ägnar 41 minuter i veckan åt olika mentala träningsformer, dock med stor individuell spridning.

The study was conducted through a web-based survey with 47 respondents (28 men, 19 women, age 16-37, M=25) from five sports; handball, ice hockey, soccer, tennis and track and field. The results showed that the athletes spend on average 41 minutes a week on different types of m
This paper investigates resilient performance of Air Traffic Management with future Artificial Intelligence (AI)-based tools. A case study was performed on an early prototype of an AI-enabled Flight Information Service (FIS) tool, using a survey of flight instructors and air traffic controllers, and a focus group with controllers with flying experience. The study focused on what characterizes good
