Nyttan med virtuella provrum : En utvärderingsstudie av virtuella provrum för online-shopping, med fokus på användbarhet.

Preniqi, Adelina, Morina, Besa January 2009 (has links)
Den relativt nya företeelsen BrandME – I am the brand är en eTjänst som fungerar som ett virtuellt provrum och därmed gör det möjligt att kunna prova på kläder virtuellt. Till sin hjälp har man bland annat använt sig av 3D-grafik samt databaser. BrandME är en produkt av det kanadensiska företaget My Virtual Model, ett företag som har arbetat med att sätta standarder för virtuell identitet sedan år 2000.Då denna företeelse är relativ ny, skapar detta utrymme för undersökning och bedömning om huruvida välutvecklad och välanpassad BrandME är. Undersökningens syfte är att utvärdera BrandME för att sedan kunna fastställa nyttan med denna eTjänst. Under utvärderingen koncentrerar vi oss dels på användbarheten hos BrandME och dels på utformningen av BrandME.

The Investigation of Interaction Relationship between the Regionally Private Radio Station and the Community Public ~Using the Example of AM Radio Stations in Big Tainan Area

Chen, Der- chin 22 July 2004 (has links)
Due to the fact that communication technologies are abruptly changing, and also that the restrictions of broadcasting (channel) industry have been gradually released, regionally AM radio stations are confronting with challenges coming from internal and external environments. Under such a situation of high competitions in media industry, regionally private radio stations are eager to understand their existence values and future development potentials, and which are also the issues that the scholars are intending to investigate. Based on the point of view of business operation, this study is to investigate the mutual relationships among three constructs, including ¡§the listening needs and motives of the community audiences¡¨, ¡§the existence necessity of regional AM radio stations¡¨ and ¡§the interaction effectiveness between radio station and the community public¡¨. Furthermore, this study also investigates the possible influences of the interaction effectiveness (between radio station and the community public) on the business operation of radio station. Through the investigations performed, the existence and development values of radio stations can be then verified. Besides, it is also expected that the operational performance of radio station can be further improved through paying much attention to the interaction effectiveness of being with the community public. The investigation is performed through the questionnaire method, by which the sampling body is regarding the adult audiences of regional AM radio stations in big Tainan area. The number of effective questionnaire is 259. According to the result of statistical analysis conducted, it is found that the audiences still positively evaluate the existence and development of regional AM radio station; and this shows that the audiences still highly are expecting the existence and further development of regional AM radio station. According to the research results, five suggestions are proposed to the regionally AM radio stations, including: (1) make the radio station operation to be more professional, to increase the competence (2) brand-making and market-positioning, to let the audiences to be loyal to these channels (3) adopting the program segmentation, to use the right person, the right time, the right contents (4) periodically holding some activities, to build up the emotion with the audiences (5) linking with the local resources, to build up the local styles. Besides, it is concluded that, at this moment, the strategic ambition and execution capability of the chief conductor of the radio station are the key factors for the success of business operation; and it won¡¦t produce the performance improvement by only talking without further execution.

The Effects of Photosynthetic Bacteria and Mycorrhizae on Phytoremediation for Soils Contaminated by Heavy Metals (Cd, Cu, Pb and Zn)

Tseng, Chii-ching 09 February 2009 (has links)
Heavy metals are one of the most important environmental pollutants. In recent years, many low cost stretages of bioremediation for contaminated sites by heavy metals, such as fungi, bacteria and plants have been investigated for their biosorption capacity towards heavy metals. The uses of plant species for remediate contaminated sites by heavy metals are so called phytoremediation. The purpose of the first parts of this study are to (1) evaluate bioavailability of Cadmium (Cd) in contaminated soil and phytoremediation potential by three plant species, Vetiveria zizanioides, Pteris multifida, and Alternanthera philoxeroides (Mart.), and (2) realized the influence of photosynthetic bacteria (PSB) on the uptake of Cd in the three species. The results showed that the Alternanthera philoxeroides (Mart.) could accumulate the highest concentration of Cd among the three species, in which the Cd concentration of plant tissue increased with the concentration in soil. The highest concentration of Cd (164.9 mg kg-1) was found in the below-ground parts of Alternanthera philoxeroides (Mart.) at the 8th week of culturing period. However, the species of Vetiveria zizanioides could accumulate the largest total Cd, up to 547.5 £gg/ plant, which thus extracted the greatest amounts of Cd from the soil. Therefore, in the first part of this study the species of Vetiveria zizanioides was concluded to be the best accumulator among the three plant species. In addition, the concentration of Cd in the species of Pteris multifida was found significantly increased after PSB was added into the soil, but the plants died later due to Cd stress. The experimental results also showed that PSB seemed to be not suitable for each species used in this study to accumulate Cd from Cd-contaminated soil. In the second part of this research, both pot and field experiments were conducted to (1) evaluate bioavailability of copper (Cu), lead (Pb) and zinc (Zn) in contaminated soil and phytoremediation potential by domesticated plants, Bidens pilosa and Passiflora foetida inoculated with arbuscular mycorrhizal (AM) fungi, and to (2) compare the results of pot and field experiments. The plant species of Bidens pilosa inoculated with AM fungi had significantly higher Cu concentrations in the shoots and roots than non-inoculated plants. The plant species of Passiflora foetida inoculated with AM fungi also had significantly higher Cu and Pb concentrations in the roots than non-inoculated plants. When we found that the root dry weight of Passiflora foetida inoculated with AM fungi dramatically increased, the concentrations of Cu, Pb and Zn in the root of the plant species increased by 9-14 times, comparing with the plants without inoculation of AM fungi. The AM fungi have potential either to promot plant growth or to increase heavy metal accumulation. The values of element translocation proportion from root to shoot was Zn>Cu>Pb for the plant species in both pot and field experiments. For both experiments, the results of pot test and field test were significantly different. The concentrations of pot tests were found higher than the field tests, and some values of pot tests were even found significantly greater than those in the field tests. In the third part of this study, the field experiments were conducted to test the feasibility of using domesticated vegetations for phytoremediation of the contaminated farmland. The objectives of this study were (1) to acquire information about the ability of five plant species growing wild in the polluted area to accumulate Cu, Pb and Zn, (2) to investigate the season effects on phytoremediaton of five plant species and evaluate the total uptake of heavy metal, and (3) to run both pot tests and a field trial of phytotremediation to compare their differences. The experimental results showed that three maximum toxic elements in a pot were 3020 mg kg-1 Pb, 232 mg kg-1 Cu and 1012 mg kg-1 Zn respectively. The Cu concentrations of the five plant species collected from the polluted plots ranged from 0.7 to 17.43 mg kg-1. The range of variation of Pb in plant tissues was measured varied from 2.29 to 81.65 mg kg−1, while a wide range of Zn concentrations was found from 12.84 to 192.85 mg kg-1 among the plants collected at the contaminated plots. In comparison to winter season, the Zn concentrations in Broussonetia papyrifera, Passiflora foetida and Saccharum sinensis collected in summer season was significantly higher. The higher Cu concentrations were obtained in both plant species of Bidens pilosa and Mimosa diplotricha in summer season. However, Pb concentrations in Saccharum sinensis collected in winter were significantly higher than those in the same plant species collected in summer. Bidens pilosa was also found having the highest total amount of Cu and Zn. The highest total amount of Pb was found in Mimosa diplotricha. For both plant species, both of the pot and field tests were different.

Ambipolar independent double gate FET (Am -IDGFET) logic design : methods and techniques

Jabeur, Kotb 11 September 2012 (has links) (PDF)
The continuous growth of global demand for semiconductor products (in a broad range of sectors, such as security, healthcare, entertainment, connectivity, energy, etc.) has been both enabled and fuelled by Moore's law and regular doubling of circuit density and performance increases. However, as CMOS technology scaling begins to reach its theoretical limits, the ITRS predicts a new era known as "Beyond CMOS". Novel materials and devices show an ability to complement or even replace the CMOS transistor or its channel in systems on chip with silicon-based technology. This has led to the identification of promising phenomena such as ambipolar conduction in quasi one- and zero-dimensional structures, for example in carbon nanotubes, graphene and silicon nanowires. Ambipolarity, in a dual-gate context (DG-FETs), means that n- and p-type behavior can be observed in the same device depending on the backgate voltage polarity. In addition to their attractive performances and the low power consumption, ambipolar double gate devices enable the development of completely new circuit structures and design paradigms. Conventional logic synthesis techniques cannot represent the capability of DG-FETs to operate as either n-type or p-type switches and new techniques must be found to build optimal logic. The work in this thesis explores design techniques to enable the use of such devices by defining generic approaches and design techniques based on ambipolar DG-FETs. Two different contexts are tackled: (i) improving standard cell logic design with more compact structures and better performance, as well as low-power design techniques exploiting the fourth terminal of the device, and (ii) adapting conventional logic synthesis and verification techniques such as Binary Decision Diagrams or Function Classification to ambipolar DGFETs in order to build reconfigurable logic cells. The proposed methods and techniques are validated and evaluated in a case study focused on DG-CNTFET through accurate simulations, using the most mature and recent DG-CNTFET model available in the literature.
