Toward solutions for energy efficiency
2020
Abstract The tariff setting for district heating (DH) services is a hard regulatory procedure. This chapter is devoted to development of the simple but sufficiently accurate methodology for fast and objective evaluation of the actual costs of DH to optimize the regulatory process and to set adequate tariffs on heat production and transmission. The developed methodology is based on the data sets of Latvian DH providers, but the methodological principles are applicable in another area too. Investigation of heat production drivers and following simulation revealed the key performance indicators (KPIs): fuel type and price. By usage of intelligent benchmarking data mining methods and mathematic…
SUSTAINABLE URBAN PUBLIC TRANSPORT. A COMPARISON BETWEEN EUROPEAN AND NORTH AFRICAN CITIES
2011
The aim of paper is to carry out a benchmarking analysis among European and North African Cities in order to point out the improvement areas for a Sustainable Urban Public Transport System. The focus is to improve public transport performance, all aspects such as fares, operational effectiveness and attractiveness of the service.
Methods of spatial cluster detection in rare childhood cancers: Benchmarking data and results from a simulation study on nephroblastoma
2021
Abstract The potential existence of spatial clusters in childhood cancer incidence is a debated topic. Identification of rare disease clusters in general may help to better understand disease etiology and develop preventive strategies against such entities. The incidence of newly diagnosed childhood malignancies under 15 years of age is 140/1,000,000. In this context, the subgroup of nephroblastoma represents an extremely rare entity with an annual incidence of 7/1,000,000. We evaluated widely used statistical approaches for spatial cluster detection in childhood cancer (Ref. [22] Schundeln et al., 2021, Cancer Epidemiology). For the simulation study, random high risk clusters of 1 to 50 ad…
Impact of external costs of unplanned supply interruptions on water company efficiency: Evidence from Chile
2020
Abstract Conventional performance assessments of water companies ignore the external costs due to water supply outages. To overcome this gap, we evaluate the impact of external costs of unplanned supply interruptions on the efficiency of water companies. Two efficiency metrics, internal technical efficiency (ITE), and total technical efficiency (TTE), were estimated based on data envelopment analysis (DEA). The results evidence that the external costs of unplanned water supply interruptions impact, on average, 7.9% of the efficiency of water companies. We also explored the impact of a set of environmental variables on water company efficiency.
STRATEGIC PLANNING AND MANAGEMENT IN GOVERNMENTAL AND PRIVATE SECTOR IN LATVIA: COMPARATIVE ANALYSIS AND OPPORTUNITIES FOR IMPROVEMENT
2012
Management issues can be divided in two large groups: governmental, with its specific aims, methods and challenges, and private sector responsible for economical results, competitiveness and state revenues. Although these sectors have so much in common in sustaining the state, striving for excellence, fulfilment of European Union 2020 strategy and for the best results, they are at the same time very different. By theory and practice, one of the greatest methods how to improve performance, is benchmarking- both looking for the best in the concrete field and in different area. In the article authors compare strategic planning and management issues in governmental and private sector, thus iden…
VoxelMages: a general-purpose graphical interface for designing geometries and processing DICOM images for PENELOPE
2016
The design and construction of geometries for Monte Carlo calculations is an error-prone, time-consuming, and complex step in simulations describing particle interactions and transport in the field of medical physics. The software VoxelMages has been developed to help the user in this task. It allows to design complex geometries and to process DICOM image files for simulations with the general-purpose Monte Carlo code PENELOPE in an easy and straightforward way. VoxelMages also allows to import DICOM-RT structure contour information as delivered by a treatment planning system. Its main characteristics, usage and performance benchmarking are described in detail.
Sustainable Development Model of EU Cities Compliant with UN Settings
2021
Nowadays, the globally accepted UN concept of sustainable development (SD) is gradu®ally transferred to the city level, including small and medium-sized cities. The implementation of SD settings requires regular measurement of developmental progress to monitor the level achieved in statics and dynamics, and to make strategic decisions for the next period. The existing urban SD indicator systems and indices are not well-suited for the monitoring of specific cities. Benchmarking algorithms and mathematical modelling procedures were applied to create a methodology and mathematical model for measuring the achieved urban SD level and to ensure the most objective selection and proportions of key …
Congenital hypothyroidism: A 2020-2021 consensus guidelines update-An ENDO-European Reference Network initiative endorsed by the European Society for…
2021
Background: An ENDO-European Reference Network (ERN) initiative was launched that was endorsed by the European Society for Pediatric Endocrinology and the European Society for Endocrinology with 22 participants from the ENDO-ERN and the two societies. The aim was to update the practice guidelines for the diagnosis and management of congenital hypothyroidism (CH). A systematic literature search was conducted to identify key articles on neonatal screening, diagnosis, and management of primary and central CH. The evidence-based guidelines were graded with the Grading of Recommendations, Assessment, Development and Evaluation system, describing both the strength of recommendations and the quali…
Komercbanku un uzņēmējdarbības savstarpējas ietekmes analīze.
2017
Bakalaurā darbā tiek pētīta uzņēmējdarbības un komercbanku mijiedarbība. Darbā tiek praktiski pielietota benčmārkinga teorija, salīdzinātie iegūti rezultāti, izveidojot trīsfaktoru lineārā un nelineārā regresiju, kā arī aprēķināti sezonālie indeksi ap pakāpes trendu. Ar benčmārkinga metodes praktisko pielietojumu tiek salīdzinātas lielākās komercbankas pēc korporatīvo klientu skaita. Iegūtie rezultāti, no klientu skata punkta, palīdzēja noteikt labāko komercbanku juridiskām personām, kā arī prognozēt izsniegto kopēju komerckredītu apjoma izmaiņas Latvijā tuvākā divu gada laikā.
Benchmarking of VoIP over HSDPA and LTE performance with realistic network data
2010
The purpose of this paper is benchmark the performance of voice over IP in high speed downlink packet access and in long term evolution networks. Benchmarking is conducted in homogeneous and heterogeneous scenario layouts assuming realistic propagation data generated over Tokyo map. Tools used in this paper are two fully dynamic time driven system simulators which have been used to support 3GPP standardization work. This benchmarking study provides insights to what e.g. different radio access technologies, scheduling mechanisms and receivers do for the performance of voice over IP. This paper indicated in various scenarios that long term evolution can offer higher performance for voice over…
