Octopus-käärintäkoneiden energiankulutus : Oy M. Haloila Ab
No full textTämä opinnäytetyö tehtiin maskulaisen Oy M. Haloila Ab -yrityksen palveluksessa. Työn tarkoituksena on kartoittaa yrityksen valmistamien Octopus-käärintäkoneiden sähköenergiankulutus. Toimeksianto tuli yrityksen suunnitteluosaston esimieheltä.
Tavoitteena on mitata jokaisen Octopus-konemallin energiankulutus sekä mahdollisten lisälaitteiden vaikutus energiankulutukseen. Energiankulutusluvut kootaan käärinnän vaihekohtaisiin energiankulutuksiin, joista muodostetaan vielä yhden lavan käärintään kulutettu energia. Varsinaiset energiankulutustaulukot ovat toimeksiantajan käytössä.
Työn toteutus alkoi keskustelemalla Haloilan sähköinsinöörien kanssa mahdollisista mittausten suoritustavoista, minkä jälkeen laadittiin mittauksia varten aikataulu. Mittauksen jälkeen saatu data kirjattiin ylös tietokoneelle. Mittaustuloksia analysoidessa käytettiin apuna sähkötekniikan kirjallisuutta sekä Haloilan työntekijöiden osaamista.
Valmis opinnäytetyö antaa Haloilalle tietoa tuotteidensa sähköenergiankulutuksista, joista mm. yrityksen asiakkaat ovat olleet hyvin kiinnostuneita viime vuosina. Lisäksi työtä voidaan tulevaisuudessa käyttää apuna esimerkiksi Octopus-koneiden kehittämisessä ekologisempaan suuntaan.This thesis was commissioned by a company named Oy M. Haloila Ab from Masku. The purpose of the thesis was to chart the electricity consumption of the wrapping machines that Haloila is producing. The task was assigned by the manager of the engineering department.
The aim of the assignment was to measure the energy consumption of each machine model and the effect of possible add-on devices on energy consumption. The results of the energy consumption measurements were compiled into a table which shows the energy consumption of each phase of wrapping. These figures were then gathered in a table that shows the energy consumption of one pallet wrapping. The actual energy consumption tables have been agreed with Haloila to be kept confidential.
The work began by discussing the possible methods of measurement with electrical engineers of Haloila. The next step was to plan a schedule for the measurements. After each measurement the result was registered on the computer. Literature on electrical engineering and expertise of the employees of Haloila were used when analyzing the results of the measurements.
This thesis will give Haloila information of the energy consumptions of their products, which is something that customers have been interested in during the recent years. In addition, the results of this thesis can be used for example to help develop Octopus machines in a more ecological direction

No full textTypescript (photocopy).The effect of electron correlation on the electron distribution and bonding of diborane is examined in several basis sets. The generalized molecular orbital method is used to define optimized orbitals for the configuration interaction calculations. Electron correlation shifts electron density away from the hydrogens, both terminal and bridging, and into the interior of the cluster and increases the direct B-B contribution to the bonding. We have also calculated the dissociation energy of diborane (B(,2)H(,6) (--->) 2BH(,3)). The experimental value is 35 kcal mol('-1), while without electron correlation the theoretical value is only about 20 kcal mol('-1). Electron correlation increases the stability of the cluster by about 15 kcal mol('-1). Ab initio calculations of B(,5)H(,9), B(,5)H(,11), and 1,2-C(,2)B(,4)H(,6) have been performed in a double-(zeta) basis and with extended configuration interaction. Theoretical deformation densities are reported. Support is given for a postulated B-C-B open 3-center bond in 1,2-C(,2)B(,4)H(,6). Ab initio calculations are reported on several transition metal carbenes and their dissociated fragments. Results suggest electrophilic and nucleophilic metal carbenes arise from two different bonding schemes. Electrophilic, 18 electron, metal carbenes can be considered as bonding between singlet metal and singlet carbene fragments, whereas nucleophilic, often electron deficient, metal carbenes can be considered as bonding between triplet metal and triplet carbene fragments. The M=C dissociation energy for electrophilic (CO)(,5)Mo=CH(OH) is calculated to be 60 kcal mol('-1). The calculated M=C dissociation energy for nucleophilic CpCl(,2)Nb=CH(,2) is 72 kcal mol('-1). The latter compound appears to have a stronger (pi) bond. The calculated rotational barrier of the methylene in CpCl(,2)Nb=CH(,2) is 14.6 kcal mol('-1). The potential energy surface of the carbene in CpCl(,2)Nb=CH(,2) has been studied by ab initio techniques. M-C-H angles as small as 78(DEGREES) and M-C-R angles as large as 170(DEGREES) have been measured in metal alkylidenes, L(,n)M=CHR. Our calculations imply that these severe distortions are due to steric factors operating in a very flat potential energy surface. Distortions in 18 electron species are predicted to be smaller than in electron deficient species

No full textWe report ab initio density functional theory calculations on iron–nickel (FeNi) alloys at conditions representative of the Earth's inner core. We test different concentrations of Ni, up to ∼39 wt% using ab initio lattice dynamics, and investigate the thermodynamic and vibrational stability of the three candidate crystal structures (bcc, hcp and fcc). First of all, at inner core pressures, we find that pure Fe transforms from the hcp to the fcc phase at around 6000 K. Secondly, in agreement with low pressure experiments on Fe–Ni alloys, we find the fcc structure is stabilised by the incorporation of Ni under core pressures and temperatures. Our results show that the fcc structure may, therefore, be stable under core conditions depending on the temperature in the inner core and the Ni content. Lastly, we find that within the quasi-harmonic approximation, there is no stability field for FeNi alloys in the bcc structure under core conditions
