Abstract:

Studien handlar om att skapa förståelse kring huruvida restaurangchefer är i högre grad uppgifts- eller relationsorienterade i sitt ledarskap samt hur de hanterat corona pandemin. Studien har tagit utgångspunkt i insamling av empirisk data, för att vidare analysera materialet med hjälp av den teoretiska referensramen. Under den teoretiska referensramen har data samlats in kring de berörda ledarstilarna och hur de skiljer sig från varandra, samt hur en kris och krishantering kan se ut. Studiens empiriska avsnitt utgår ifrån en kvalitativ metod insamling där sju restaurangchefer intervjuades. Re

Abstract:

Many construction companies worldwide continue to implement different methodologies to optimize time and improve management in the execution of works; however, a lack of control in projects continues to be observed. For this reason, one of the most common problems currently is the incompletion of scheduled work. Due to this, it is necessary to keep better control of the projects at the execution stage so that the contractor can optimally, quickly, and easily manage the progress of all the specialties involved. In this sense, this research develops the use of the Plan Grid Application for data

Abstract:

Social, political and philosophical dynamics which supposedly played an important role in the formation of the grid-plan in ancient Greek cities are explored in this thesis. In this respect, the thesis aims to expose the socio-political and philosophical matrix of Greek society in which the grid was implemented with an emphasis on the concepts of equality, rationality and geometric harmony. Having formulated a theoretical framework, it concentrates on several cases from different regions and contexts in the Mediterranean in order to confirm this framework.

Abstract:

The integration of dispatchable renewable energies like biomass, geothermal and reservoir hydro technologies into an electrical network present no greater challenge than the integration of conventional power technologies for which are well understood by Eskom engineers. However, renewable energies that are based on resources that fluctuate throughout the day and from season to season, like wind and solar, introduce a number of challenges that Eskom engineers have not dealt with before. It is current practice for Eskom‟s generation to follow the load in order to balance the demand and supply.

An energy saving opportunity exists in mining and smelting industries such as the Ferrochrome industry, in the form of waste heat extraction and recovery. The mining and smelting of metals requires the use of high-power, AC or DC electric-arc furnaces that melt raw feed material in order to separate and produce useful metals from the feed. The smelting of raw materials into metals inside arc furnaces produces large quantities of hot gas as by-products, according to specific process-controlled chemical reactions.

The thesis is concerned with the study of the dynamic responses of a supercritical coal-fired power plant via mathematical modelling and simulation. Supercritical technology leads to much more efficient energy conversion compared with subcritical power generation technology so it is considered to be a viable option from the economic and environmental aspects for replacement of aged thermal power plants in the United Kingdom. However there are concerns for the adoption of this technology as it is unclear whether the dynamic responses of supercritical power plants can meet the Great Britain Grid

En strömbrytare är en säkerhetsanordning som är utformad för att bryta strömmen om ett problem uppstår. Det finns ett flertal olika typer av brytare beroende vilket spänningsområde som avses. Brytare för lågspänning används för hushållsapparater, medan högspänningstyper används för överföring av spänning i elnätet. Högspänningsbrytare använder idag svavelhexafluorid (SF6)-gas, som ett isolerande medium för att släcka den elektriska ljusbåge som bildas när strömmen bryts. SF6 är dock problematiskt för miljön, då dess globala uppvärmningspotential (GWP) är 23 500 gånger högre jämfört med koldiox

Abstract:

Remote hybrid power systems (RHPS) serve local off-grid loads or various island grids when no grid extension is possible. They combine renewable resources, conventional generators and energy storage systems in order to balance the load at any moment, while ensuring power quality and energy security similar to large centralized grids. Modelling such a complex system is crucial for carrying out proper simulations for predicting the system’s behavior and for optimal sizing of components. The model should include an estimation of the renewable resource availability over the period of the simulatio

Le but principal du présent travail est ainsi de réaliser une expérience de mélange par la turbulence, dans laquelle il est possible de déterminer et de quantifier les temps de cohérence des différentes échelles spatiales des fluctuations du champ de vitesse et du champ de concentration qu'il transporte et mélange. La turbulence est ici voisine de la situation idéale statistiquement homogène et isotrope, et la configuration est conçue pour qu'il en soit de même pour le champ de concentration. La turbulence est créée par une grille placée perpendiculairement à un écoulement uniforme à l'extérie

Abstract:

Fossil fuels and non-renewable resources are being replaced with, as modern day society has coined the term, green energy. This movement towards green energy creates a demand for renewable energy resources, such as solar photovoltaic (PV) systems. This study used Geographic Information Systems (GIS) in conjunction with Remote Sensing (RS) practices and two weighting systems the Analytical Hierarchy Process (AHP) and Rank-Order methods for PV site selection. Six multi-criteria models were developed using spatial factors and constraining images to locate potential photovoltaic power plant sites

In this report the design and testing of a plug and play system to run Coolfinity’s Icevolt 300 refrigerator on solar panels is discussed. Such a system will be able to provide adequate cooling for food & beverages in area’s with unreliable or no electricity available. Currently such systems are only available for small chest refrigerators, while the Icevolt 300 is a large standing commercial refrigerator with a glass door. This is ideal for shops, cafés restaurants and smaller distribution centres. The system contains a solar charge controller, a battery and an inverter. First the compone
