Advertising on Social Networking Websites
The rise of social networking websites such as MySpace and Facebook over the past decade has been nothing short of phenomenal. Once regarded as nothing more than a passing fad , these websites have grown to astronomical proportions; each website currently boasts 60+ million unique visitors each month. Certain businesses are beginning to notice the potential for reaching out to their target audiences through this new medium and have already begun a series of advertising efforts in order to do so; however, the spend on this form of advertising is relatively minor compared to other efforts. This paper will establish why social networks are important to businesses as an advertising medium and attempt to review the current advertising methods that are in place
Investigations On Rf Sputter Deposited Sicn Thin Films For Mems Applications
With the rapid increase in miniaturization of mechanical components, the need for a hard, protective coatings is of great importance. In this study we investigate some of the mechanical, chemical and physical properties of the SiCN thin films. Thin films of amorphous silicon carbide nitride (a-SiCxNy) were deposited in a RF magnetron sputtering system using a powder pressed SiC target. Films with various compositions were deposited on to silicon substrate by changing the N2/Ar gas ratios during sputtering. Nano-indentation studies were performed to investigate the mechanical properties such as hardness and reduced modulus of the SiCN films. Surface morphology of the films was characterized by using atomic force microscopy (AFM). X-ray photoelectron spectroscopy (XPS) data indicated that the chemical status is highly sensitive to the nitrogen ratios during sputtering. Further, the films were annealed in dry oxygen ambient in the temperature range of 400 900°C and characterized using XPS to investigate the chemical composition and oxidation kinetics at each annealing temperature. The surface roughness of these films was studied as a function of annealing temperature and film composition with the help of a Veeco optical profilometer. Nano-indentation studies indicated that the hardness and the reduced modulus of the film are sensitive to the N2/Ar ratio of gas flow during sputtering. AFM studies revealed that the films become smoother as the N2/Ar ratio is increased. XPS data indicated the existence of C-N phases in the as-deposited films. The study of oxidation kinetics of RF sputter deposited SiCN thin films, using XPS, suggest that N2 co-sputtering helps to suppress the formation of a surface oxide, by allowing un-bonded Si to bond with N and C inside the vacuum chamber as opposed to bonding with O in atmosphere
The Role Social Media Influencers Play in a Company\u27s Brand
Influencer marketing is a tactic that many companies have had to integrate into their businesses to better communicate with consumers. The purpose of this research is to analyze the role influencer marketing plays in a company\u27s brand. This study assesses the way consumers build trust and relationships with companies through the help of influencers. There are many variables that come into play, for example, emotional attachment, authenticity, and loyalty are just three that have been measured in previous studies. These same variables are used in this research to see if they can also apply to a company that uses influencers versus one that does not. Friestad and Wright\u27s (1994) persuasion knowledge model (PKM) is applied in this study from a theoretical perspective; the theory focuses on how people use their knowledge of persuasion motives and tactics to interpret, evaluate, and respond to influence attempts from marketers. A cross-sectional survey of 105 respondents that use social media was conducted to test six proposed hypotheses. Participants were asked to respond to the survey questions based on at least one company or brand they follow on social media. The findings show that brand attitudes toward a company that uses influencer marketing are not more positive than a company that does not. The amount of time a consumer follows a brand on social media does not have an impact on their brand attitude. The level of authenticity toward a brand has no relationship with influencer marketing and the use of influencer marketing does not affect the emotional attachment toward the brand nor does it contribute to consumer brand trust. Emotional attachment and brand trust increase consumer loyalty, but authenticity does not. It was found that influencer marketing for this sample population is not recommended when attempting to increase the respective variables. This study also provides useful insights about college students and their social media interests
Investigation Of Reactively Sputtered Boron Carbon Nitride Thin Films
Research efforts have been focused in the development of hard and wear resistant coatings over the last few decades. These protective coatings find applications in the industry such as cutting tools, automobile and machine part etc. Various ceramic thin films like TiN, TiAlN, TiC, SiC and diamond-like carbon (DLC) are examples of the films used in above applications. However, increasing technological and industrial demands request thin films with more complicated and advanced properties. For this purpose, B-C-N ternary system which is based on carbon, boron and nitrogen which exhibit exceptional properties and attract much attention from mechanical, optical and electronic perspectives. Also, boron carbonitride (BCN) thin films contains interesting phases such as diamond, cubic BN (c-BN), hexagonal boron nitride (h-BN), B4C, β-C3N4. Attempts have been made to form a material with semiconducting properties between the semi metallic graphite and the insulating h-BN, or to combine the cubic phases of diamond and c-BN (BC2N heterodiamond) in order to merge the higher hardness of the diamond with the advantages of c-BN, in particular with its better chemical resistance to iron and oxygen at elevated temperatures. New microprocessor CMOS technologies require interlayer dielectric materials with lower dielectric constant than those used in current technologies to meet RC delay goals and to minimize cross-talk. Silicon oxide or fluorinated silicon oxide (SiOF) materials having dielectric constant in the range of 3.6 to 4 have been used for many technology nodes. In order to meet the aggressive RC delay goals, new technologies require dielectric materials with
A Framework for Computational Design and Adaptation of Extended Reality User Interfaces
To facilitate high quality interaction during the regular use of computing
systems, it is essential that the user interface (UI) deliver content and
components in an appropriate manner. Although extended reality (XR) is emerging
as a new computing platform, we still have a limited understanding of how best
to design and present interactive content to users in such immersive
environments. Adaptive UIs offer a promising approach for optimal presentation
in XR as the user's environment, tasks, capabilities, and preferences vary
under changing context. In this position paper, we present a design framework
for adapting various characteristics of content presented in XR. We frame these
as five considerations that need to be taken into account for adaptive XR UIs:
What?, How Much?, Where?, How?, and When?. With this framework, we review
literature on UI design and adaptation to reflect on approaches that have been
adopted or developed in the past towards identifying current gaps and
challenges, and opportunities for applying such approaches in XR. Using our
framework, future work could identify and develop novel computational
approaches for achieving successful adaptive user interfaces in such immersive
environments.Comment: 5 pages, CHI 2023 Workshop on The Future of Computational Approaches

Technology of Steel Tube Making
The manufacture of steel tubes which are used for a wide range of applications, involves large variety of prod-uction processes. Depend-ing upon the end use and econ-omics, different processes used for steel tube making can be classified broadly into two distinct groups: (a) Welded, and (b) Seamless Under the category of welded tubes, the two main processes available are (i) Electric Resistance Welding (ERW/HFIW) and (ii) Furnace Butt Welding (HFW/Fretz Moon). Electric Resistance Welded tubes are manufactured using direct or high frequency induced current in formed circular hot or cold rolled steel. strips. This process has also undergone remarkable advan-cement in the technology in terms of both production and quality, in the recent past. Furnace Butt Welding is effected by pressure welding, where the entire strip is heated in a tunnel furnace and the edges are further heated to a temperature near fusion point & then pressed together. This process is also called as Fretz Moon Process. Under the category of seamless process, the three main stages involved are piercing, elongation and sizing/ stretch reducing. Over the years considerable developments have taken place in the area of seamless tube making to improve the process with respect to yield, wall thickness tolerance, diameter to thickness ratio and towards manu-facturing tubes of larger variety of steel grades
