Primary Commodity Prices: Co-movements, Common Factors and Fundamentals
2011
The behavior of commodities is critical for developing and developed countries alike. This paper contributes to the empirical evidence on the co-movement and determinants of commodity prices. Using nonstationary panel methods, we document a statistically significant degree of co-movement due to a common factor. Within a Factor Augmented VAR approach, real interest rate and uncertainty, as postulated by a simple asset pricing model, are both found to be negatively related to this common factor. This evidence is robust to the inclusion of demand and supply shocks, which both positively impact on the co-movement of commodity prices.
Simulation of photovoltaic installation connected to the grid with storage system
2017
Abstract In the present paper, a new approach for the management of energy resources in a research laboratory is proposed and evaluated. A simulation study for the photovoltaic (PV) installation was conducted under the Tunisian-Italian cooperation project DE.DU.ENER.T, using renewable energy and economic criteria. The aim of the study is to improve the energy efficiency in order to minimize the electricity cost consumed in the laboratory. A Hybrid Renewable Energy System consisting of a photovoltaic field of 12KWc was installed to reduce the exorbitant bills, due to intensive energy equipment such as drying ovens and workstations, using sustainable, green and clean sources. In addition, a s…
Forecasting Electricity Consumption and Production in Smart Homes through Statistical Methods
2022
Abstract Over the last years, a steady increase in both domestic electricity consumption and in the adoption of personal clean energy production systems has been observed worldwide. By analyzing energy consumption and production on photovoltaic panels mounted in a house, this work focuses on finding patterns in electrical energy consumption and devising a predictive model. Our goal is to find an accurate method to predict electrical energy consumption and production. Being able to anticipate how consumers will use energy in the near future, homeowners, companies and governments may optimize their behavior and the import and export of electricity. We evaluated the ARIMA and TBATS statistical…
Familial hypercholesterolæmia in children and adolescents: Gaining decades of life by optimizing detection and treatment
2015
Contains fulltext : 155263.pdf (Publisher’s version ) (Open Access) Familial hypercholesterolaemia (FH) is a common genetic cause of premature coronary heart disease (CHD). Globally, one baby is born with FH every minute. If diagnosed and treated early in childhood, individuals with FH can have normal life expectancy. This consensus paper aims to improve awareness of the need for early detection and management of FH children. Familial hypercholesterolaemia is diagnosed either on phenotypic criteria, i.e. an elevated low-density lipoprotein cholesterol (LDL-C) level plus a family history of elevated LDL-C, premature coronary artery disease and/or genetic diagnosis, or positive genetic testin…
Restorāna mājas lapa
2015
Kvalifikācijas darba mērķis ir izstrādāt tīmekļa vietni reāli eksistējošam restorānam ar tai piesaistītu administrācijas paneli un datu bāzi, kuras nolūks ir optimizēt uzņēmuma darbību, veicinot klientu piesaisti, kā arī efektīvi pārvaldot elektroniski uzglabāto informāciju. Sistēmas administrācijas panelis paredzēts restorāna darbinieku un īpašnieku iekšējai lietošanai, lai ērti varētu rediģēt mājas lapā publicēto informāciju, kā arī uzglabāt vēl nepublicētus datus, pievienotu vai rediģētu sistēmas lietotājus, piešķirot vai atņemot tiem piekļuves tiesības dažādām lapas sadaļām. Sistēma izstrādāta uz Python/Django ietvara bāzes, izmantojot MySQL datu bāzu pārvaldības rīku.
Interneta veikala izstrāde
2016
Kvalifikācijas darba mērķis ir izveidot interneta veikalu ar tam piesaistītu administrācijas paneli. Sistēmā ir trīs lietotāju grupas - nereģistrēti lietotāji, reģistrēti lietotāji un administrācija. Sistēmas administrācijas panelis paredzēts interneta veikala administrācijai, lai varētu ērti un vienkārši pārvaldīt interneta veikalu. Tas veidots tā, lai darbinieks bez agrākas programmēšanas pieredzes spētu ērti un pilnvērtīgi pārvaldīt interneta veikalu. Sistēma izstrādāta kā tīmekļa vietne, izmantojot PHP programmēšanas valodu. Dati glabājas MySQL datubāzē.
Experimental assessment of the shield-to-salt-fog properties of basalt and glass fiber reinforced composites in cork core sandwich panels applications
2018
Abstract In this paper, the effect of salt-fog exposition on the mechanical behavior of sandwich panels having cork agglomerate core was investigated. In particular, the aim of this research work is to assess the shield function of unidirectional basalt and E-glass reinforced polymer on the aging and failure mechanism of the core when such class of material are destined to operate in hostile environments (e.g., marine environment). To do this, the manufactured sandwich panels were exposed up to 60 days to salt-fog environment, according to ASTM B 117 standard. Unaged and aged specimens were analyzed through three point bending tests after aging time of 10, 25 and 60 days. Digital Image Corr…
A dynamic panel study on digitalization and firm's agility: What drives agility in advanced economies 2009–2018
2021
Abstract Firm agility today is not a factor of competitiveness or success but a survival instrument on the market. Disruptive innovations and technological advancement, together with digitalization, change the role of firm agility. We show that the link between the national/industry level of digitalization and firm agility is statistically robust and essential. We study the link on data from 2009 to 2018 in fifteen EU advanced economies using dynamic panel data modeling. The digitalization impact level differs across firms by ownership type (family to non-family firms). Agility in family firms is strongly influenced by the national/industry level of digitization and investments in intangibl…
A NEXT GENERATION SEQUENCING APPROACH FOR MOLECULAR DIAGNOSIS OF MONOGENIC DYSLIPIDEMIAS
New Evidence of the Real Interest Rate Parity for OECD Countries Using Panel Unit Root Tests with Breaks
2006
This paper tests for real interest parity (RIRP) among the nineteen major OECD countries over the period 1978:Q2-1998:Q4. The econometric methods applied consist of combining the use of several unit root or stationarity tests designed for panels valid under cross-section dependence and presence of multiple structural breaks. Our results strongly support the fulfillment of the weak version of the RIRP for the studied period once dependence and structural breaks are accounted for.
