Diffusion of Software Technology Innovations in the Global Context
2002
This study examines how software businesses are acquiring new software technology innovations (STIs) in rapidly changing globalized business environment characterized by rapidly shortening software technology life cycles, changing customer demands, and intense competition. It was executed through both theoretical and empirical investigations and analyses. It describes one case company as an example of the diffusion of STI and develops a framework for the diffusion of software technology innovation. The research findings are useful for both further research and industrial settings. peerReviewed
Modelling flow and heat transfer in spacer-filled membrane distillation channels using open source CFD code
2013
Abstract A good understanding of the details of hydrodynamic and heat transport conditions and their impact on temperature polarisation and pressure drops is essential for optimum design of membrane distillation (MD) modules. To this end, the present work reports on initial progress in the development of a tool for 3D simulation of spacer-filled MD channels based on the open source CFD code library OpenFOAM. The paper discusses a number of modelling and implementation aspects including model geometry and computational domain, choice of boundary conditions, and discretisation schemes. The results pertaining to the effect of three different spacer types on the fluid dynamics and heat transfer…
Friction and Heat Transfer in Membrane Distillation Channels: An Experimental Study on Conventional and Novel Spacers
2022
The results of an experimental investigation on pressure drop and heat transfer in spacer-filled plane channels, which are representative of Membrane Distillation units, are presented and discussed. Local and mean heat transfer coefficients were obtained by using Thermochromic Liquid Crystals and Digital Image Processing. The performances of a novel spacer geometry, consisting of spheres that are connected by cylindrical rods, and are hereafter named spheres spacers, were compared with those of more conventional woven and overlapped spacers at equal values of the Reynolds number Re (in the range ~150 to ~2500), the pitch-to-channel height ratio, the flow attack angle and the thermal boundar…
Multilevel functional surgery in adults with acquired spasticity of upper extremity
2004
The authors present their expertise in the treatment of acquired spasticity of the upper extremity in adults, illustrating the basics of modern functional surgery, which benefits from the achievements in bioengineering and information technology and new surgical techniques. Moreover close cooperation between the physical therapist and surgeon is essential in planning a new treatment scheme which, when possible, may successfully strengthen and optimize the function control of the remaining extremity, thus overriding the old concept of merely correcting the deformity. Results depend on proper scrutiny of the preoperative clinical and instrumental details on successful surgical accomplishment …
SCOPE-Based Emulators for Fast Generation of Synthetic Canopy Reflectance and Sun-Induced Fluorescence Spectra
2017
Progress in advanced radiative transfer models (RTMs) led to an improved understanding of reflectance (R) and sun-induced chlorophyll fluorescence (SIF) emission throughout the leaf and canopy. Among advanced canopy RTMs that have been recently modified to deliver SIF spectral outputs are the energy balance model SCOPE and the 3D models DART and FLIGHT. The downside of these RTMs is that they are computationally expensive, which makes them impractical in routine processing, such as scene generation and retrieval applications. To bypass their computational burden, a computationally effective technique has been proposed by only using a limited number of model runs, called emulation. The idea …
Potencjał finansowy sportowych organizacji pożytku publicznego
2020
Struktura źródeł pochodzenia przychodów może oddziaływać na sposób funkcjonowania i zakres działań podejmowanych przez organizacje pozarządowe. Instytucjonalny system organizacji sportu, jak również zasady finansowania organizacji pozarządowych objawiają się tym, że jednym z głównych źródeł ich przychodów są środki publiczne. Dlatego założono, że udział środków publicznych w przychodach ogółem różnicuje społeczne organizacje sportowe. Uznano to za czynnik, który w świetle teorii zależności od zasobów oraz zjawiska izomorfizmu instytucjonalnego może negatywnie kształtować warunki funkcjonowania organizacji pozarządowych. Celem badań było zidentyfikowanie struktury przychodów niekomercyjnych …

Quantitative reconstruction of hydroclimate variability over the last 200 kyr in the West Mediterranean
2022
The data show the quantitative annual, winter and summer precipitation reconstructions (mm/yr) from southern Iberian Peninsula for the last ~200,000 years (Camuera et al., 2022), based on the previously published fossil pollen data from the Padul-15-05 lake sediment record (Ramos-Román et al., 2018a, b; Camuera et al., 2019, 2021). The Padul-15-05 record, located in southern Spain (37º00'39''N, 3º36'14''W, 726 masl), was retrieved during summer 2015 from the current edge of the lake using a Rolatec RL-48-L hydraulic percussion coring machine. The quantitative precipitation reconstructions were performed using the performance statistics of the Weighted Averaging-Partial Least Squares (WA-PLS…
