Background: Presumed effects of global warming on occupational heat stress aggravate conditions in many parts of the world, in particular in developing countries. In order to assess and evaluate conditions, heat stress must be described correctly and measured correctly. Objective: Assessment of heat stress using internationally recognized methods. Design: Two such methods are wet bulb globe temper

This paper presents a constructive algorithm for memory-aware task assignment and scheduling, which is a part of the prototype system MATAS. The algorithm is well suited for image and video processing applications which have hard memory constraints as well as constraints on cost, execution time, and resource usage. Our algorithm takes into account code and data memory constraints together with the

To overcome the bottleneck of the one-way translation from VR (virtual reality) to CAD in VR-based CAD system, this paper proposes a Web-based VR-CAD system WVCD (Web-based virtual conceptual designer) to support both customers’ and design team members' involvement in the conceptual design and analysis activity over the Internet. It provides users with both parametric and freehand methods to creat

The Neumann--Neumann method is a commonly employed domain decomposition method for linear elliptic equations. However, the method exhibits slow convergence when applied to semilinear equations and does not seem to converge at all for certain quasilinear equations. We therefore propose two modified Neumann--Neumann methods that have better convergence properties and require less computations. We pr

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To assess the benefits and harms of decongestants and antihistamines in the treatment of AOM in children. Specifically, we want to assess the impact of decongestants and antihistamines on the presence of otalgia, the persistence of AOM, the need for or change in antibiotic therapy, severe complicat

Background: A new Chronic Kidney Disease Epidemiology Collaboration equation without the race variable has been recently proposed (CKD-EPIAS). This equation has neither been validated outside USA nor compared with the new European Kidney Function Consortium (EKFC) and Lund-Malmö Revised (LMREV) equations, developed in European cohorts. Methods: Standardized creatinine and measured glomerular filtr

Modern gearing applications, in particular electrification, impose new challenges in many different fields of engineering and research. In specific, new demands are imposed on gears, including higher rotational speed, lower noise acceptance, and increased efficiency, as well as increased resistance against pitting and scuffing. To meet these demands, a better understanding of gear contacts is need

The pre-tetramerization loop (PTL) of the human tumor suppressor protein p53 is an intrinsically disordered region (IDR) necessary for the tetramerization process, and its flexibility contributes to the essential conformational changes needed. Although the IDR can be accurately simulated in the traditional manner of molecular dynamics (MD) with the end-to-end distance (EEdist) unhindered, we sough

Current precision cancer medicine is dependent on the analyses of a plethora of clinically relevant genomic aberrations. During the last decade, next-generation sequencing (NGS) has gradually replaced most other methods for precision cancer diagnostics, spanning from targeted tumor-informed assays and gene panel sequencing to global whole-genome and whole-transcriptome sequencing analyses. The shi

As supply uncertainties and increased lead times were more prominent than ever during the covid-19 pandemic, many companies experienced disrupted supply chains and realized the weaknesses in their inventory management and supply chain planning. Many organizations, including the case company in this thesis, Beijer Ref, experienced the impact of the bullwhip effect on their operations. The bullwhip

Adsorption is an important separation technique in chemical engineering, capable of achieving a high purity of product. As it is also capable of concentrating even very low concentrations it was investigated as a possible method to concentrate the product of an ammonia plasma reactor in the EU DARE2X project. As the development of adsorption systems is expensive and time consuming, a simulation of

Early designs are often based on rough estimations and assumptions. Such is also the case when designing space turbines that power rocket engine fuel pumps which generally have obscure performance and size requirements. Often times, this leads to unique, single-use designs. This complicates and restricts the amount of possible testing. To aid in this early design process and to help predict turbin

This thesis investigates the integration of the individual learning rates from Rprop into SGD and Adam optimization methods. The individual learning rates are updated separately from the weights. A major focus of this work is the role of mini-batch size in updating these learning rates. Empirical analysis demonstrates that selecting an appropriate mini-batch size can accelerate convergence and imp
