Route search requires a useful and accurate algorithm to calculate the distance between two objects, especially on a round surface such as the earth. This algorithm provides a considerable circle distance between two locations on a non-flat surface. The distance of the two objects is determined based on longitude and latitude. Haversine is an algorithm that can determine the distance between two o

An investigation into the implementation state of open standards in software is currently ongoing through the ISPRS/EuroSDR 'GeoBIM benchmark 2019' initiative, which kicked off earlier this year. The benchmark activity provides a way of assessing and comparing the functionality of different software packages in GIS and BIM in terms of their ability to handle standardised data (IFC and CityGML) and

In both the Geo and BIM domains, it is widely acknowledged that the integration of geo-data and BIM-data is beneficial and a crucial step in facing the multi-disciplinary challenges of our built environment. The result of this integration - broadly termed as GeoBIM - has a range of potential uses from district study to road safety. However, from the data perspective, this integration raises the qu

There is no tradition in Annals of Regional Science that the editors write editorials. However, as of 2020, the editors will each year write an editorial in which we report as well as refect on recent developments of the journal. We hope that this will be of interest for our readers. This editorial is the frst one and marks the start of the strategy to write a yearly editorial. We, i.e., Martin An

Background: Providing continuous follow-up care to patients with congenital heart disease (CHD) remains a challenge in many settings. Previous studies highlight that patients with CHD experience discontinuation of follow-up care, but mainly describe a single-centre perspective, neglecting inter-institutional variations. Hospital-related factors above and beyond patient-related factors are believed

A numerical simulation is performed to identify the material parameters of an elastic/visco-plastic material under tensile impact loading. The identification is based on an inverse analysis using the Kalman filter technique and the finite element method. The input data to the inverse analysis are the time histories of the strains on specimens. The measurement errors can be treated reasonably by thA numerical simulation is performed to identify the material parameters of an elastic/visco-plastic material under tensile impact loading.

Low-temperature operation of solid oxide fuel cells (SOFCs) results in deterioration in electrochemical performance due to sluggish oxygen reduction reaction (ORR) at the cathode. To enhance the reaction pathway for ORR, La0.8Sr0.2MnO3 (LSM) nanofibers were fabricated by electrospinning and used for low-temperature solid oxide fuel cells operated at 600–700 °C. The morphological and structural cha

Diluting the combustion mixtures is one of the advanced approaches to reduce the NOx emission of methane/air premixed turbulent flame, especially with high diluents to create a distributed reaction zone and mild combustion, which can lower the temperature of reaction zone and reduce the formation of NOx. The effect of N2/CO2 dilution on the combustion characteristics of methane/air premixed turbul

Foetal and neonatal alloimmune thrombocytopenia (FNAIT) is the platelet counterpart of haemolytic disease of the foetus and newborn. Among Caucasians, around 80 % of FNAIT cases and some of the most severe cases, are caused by alloantibodies against the human platelet antigen 1a (HPA-1a). For around 3 decades it has been known that almost all HPA-1a-immunised women are HLA-DRB3*01:01 positive. The

AIMS: Heparin is the preferred choice of anticoagulant in percutaneous coronary intervention (PCI) for acute myocardial infarction (MI). An established dosage of heparin has not yet been determined, but treatment may be optimized through monitoring of activated clotting time (ACT). The aim of this study was to determine the relationship between heparin dose or ACT with a composite outcome of death

This study is the first to use a newly-developed material via hydrothermal method, cerium oxide nanowires doped with reduced graphene oxide (CNW-RGO) for reductive H2 production. The detailed characteristics of the CNW-RGO materials were investigated to explore the capabilities of reductive production. The mean diameter of the CNWs was uniform at 22 nm. Owing to RGO-doping, the energy gap between

Chronic lung diseases (CLDs), such as chronic obstructive pulmonary disease, interstitial lung disease, and lung cancer, are among the leading causes of morbidity globally and impose major health and financial burdens on patients and society. Effective treatments are scarce, and relevant human model systems to effectively study CLD pathomechanisms and thus discover and validate potential new targe

Purpose: Gene therapy for RPE65 retinopathy has been recently approved. The purpose of this study was to assess retinal structure and function in 3 siblings presenting with late-stage RPE65 retinopathy and to assess the unmet need for such therapy in Saudi Arabia. Methods: Search of the retinal dystrophy registry at King Khaled Eye Specialist Hospital and clinical examination including multimodal

This paper examines transaction costs in the institutional zakat system from the open innovation perspective and tries to understand its impact on performance. It attempts to harmonise the concept of transaction costs with the open innovation strategy, especially in the aspect of zakat distribution. A quantitative approach was applied in measuring the performance of zakat distribution, where the d

This paper attempts to analyze the concept of localization and its relationship with the psychological performance of zakat. It argued that localization could produce development opportunities from the management decentralization of supply chain in zakat institution. In this study, localization is treated as the mediator, while property rights of zakat and asset specificity performed as the indepe

Malaysia is one of the most rapidly growing economies in Asia and is blessed with foreign workers inflow to sustain the economic growth process. However, the strong national sentiments among the local community, which harbors ill perception towards the foreign workers, lead to regrettably vague policies concerning foreign workers. As far as this issue is concerned, Malaysia needs to reform the pol
