The paper considers multi-hop wireless mesh networks that serve multicast periodic packet traffic. The packets from each packet stream are generated at the stream's source node and traverse a number of wireless nodes in order to reach their multiple destination nodes. Packet periodicity means that a common repeatable frame of time slots is defined and that the packets to be transmitted arrive at t

In this paper a linear regression analysis is used to analyze the behavior of the inner cell of an elliptical cavity. The aim is to understand how the RF parameters are correlated to each other and how they are affected by the change of the geometric parameters. This is done by fitting the RF data to a linear model. The data is obtained by simulating a set of different inner cells automatically by

Generalized alternating projections is an algorithm that alternates relaxed projections onto a finite number of sets to find a point in their intersection. We consider the special case of two linear subspaces, for which the algorithm reduces to matrix multiplications. For convergent powers of the matrix, the asymptotic rate is linear and decided by the magnitude of the subdominant eigenvalue. In t

The sea level low stand period during the Early Mesolithic in SE Baltic (c. 9,500-6,500 BC) has resulted in vast inundated areas. Some of the sites have yielded extensive remains of lagoonal and riverine sediments, as well as areas with trees preserved in situ. Investigations at one of the sites - Haväng in eastern Scania - have resulted in archaeological findings from the entire period. The prese

This study evaluated the psychometric properties of the American English (Am. Eng.) version of the Occupational Value Assessment with predefined items (OVal-pd). The OVal-pd is a 26-item Likert-like questionnaire designed to assess the construct of occupational value as framed within the Value and Meaning in Occupations model (ValMO). Following a translation from the Swedish OVal-pd, 277 randomly

A year has passed since Anne L'Huillier became Lund University's first Nobel laureate. Since then, she has tried to use the attention to revive interest in research. But she has also had to come to terms with the oddity of becoming a science rock star asked for selfies all over town. I thought we would go back in time to the 3rd of October 2023. What do you remember most about that very special da

This article presents a study aiming to explore and evaluate acoustic comfort in residential multistory buildings in Sweden. Acoustic data was associated to self-reported responses acquired by a survey: a questionnaire was setup researching the response to noise annoyance from multiple sources in a flat and the emotional reactions of tenants to the acoustic climate at home. An assessment of acoust

The BGO Rugby Ball is a large solid angle electromagnetic calorimeter now installed in the ELSA Facility in Bonn. The BGO is operating in the BGO-OD experiment aiming to study meson photoproduction off proton and neutron induced by a Bremsstrahlung polarized gamma beam of energies from 0.2 to 3.2 GeV and an intensity of 5 × 107 photons per second. The scintillating material characteristics and the

The aim was to study the psychometric properties of the Swedish version of the Chronic Pain Coping Inventory. The material consisted of a group of 100 subjects recruited from a large population study. Pain status and the absence of pain-related sick leave during the previous year conditioned inclusion. Another group comprised 160 patients on the long-term sick list and who had been referred to a m

One of the obstacles to effective pain management in the Post-Anaesthesia Care Unit (PACU) is the lack of systematic and comprehensive methods for assessing and treating postoperative pain. Nurses' intuitive knowledge of pain were verbalized and divided into four categories of pain behaviours in the PACU-Behavioural Pain Rating Scale. The aim of the present study was to test the reliability of the

Millimeter wave pulsed radar has found many applications, among them hand gesture sensing, which this work has as purpose. This application has already shown good potential, [1], and here in this work robustness aspects are taken into account. A classification task was defined, where distinction should be made between five different small hand gestures, recorded by 18 people in total. The classifi

This study compared the realism of witnesses’ confidence judgments of their own recall elicited in either the Cognitive Interview (CI) or the Structured Interview (SI). Calibration methodology was used to analyze the realism of the confidence judg­ments. Participants (N = 56) were interviewed about their observations of a staged crime and returned two weeks later to assess their confidence in the

In a new observational study, researchers at Lund University in Sweden looked at all children listed for heart transplants in the Nordic countries between 1986 and 2023. A total of 597 children were included in the study, 461 of whom received a transplant. The results show that survival rates have increased significantly over time despite the modest volumes in the region – a development that the r

The study has been based on semi-structured interviews with 10 customers who have chosen Kalmar municipality as homecare service provider. The interviews have been conducted in conjunction with customers granted home care and with a follow-up after one-two months. By examining and analyzing the customer’s expectations and experiences at an early stage when home-care services started and then follo
