MetApp : an efficient and cost saving method for small businesses to create iOS applications

McCann, Simon Vincent 22 November 2013 (has links)
Interactions between small businesses and their customers often involve some form of electronic transaction. With the growing proliferation of portable computing, many of these transactions are taking place on a “smart device,” such as an iPhone or iPad. Many businesses will want to create their own custom apps to better serve their customers. Currently this process can be difficult and expensive to do well. This report proposes a method to make app production a little easier and cheaper. / text

Elektrodų, modifikuotų poli(N-metilanilinu), taikymas elektroanalizės tikslams / The use of poli(N-methylaniline) modified electrodes for electroanalytical application

Jasinskaitė, Zita 13 June 2006 (has links)
L – Ascorbic acid is a compound of great importance as it is vital to immune response and wound healing but it cannot be synthesised by some mammals, including humans. L- Ascorbic acid was also found to play an important role in the body as a free – radical scavenger, which may help to prevent free – radical induced diseases such as cancer and Parkinson’s disease. In foods, it is found in many fruits, especially in citrus fruits and berries, in vegetables and in beverages, especially those derived from fruit juices. Despite its wide presence in vegetables, many people do not acquire much Vitamin C this way. So very important is vitamin C. PI–50-1 model potentiostat, connected to Epsilon EC-2000-XP ( Ver.1,50,69_XP) programmer, and computer. The experiments were performed in a three-electrode cell, containing glassy carbon working electrode and counter-electrode (A = 0,07 cm2). Saturated Ag/AgCl reference electrode. All potential values reported refer to this reference electrode. The electrochemical oxidation of ascorbic acid at poly(N-methylaniline) modified electrode has been studied. The proposed mechanism explains the ability of poly(N-methylaniline) to electro-catalyze the anodic oxidation of ascorbic acid. It has been shown that poly(N-methylaniline) modified electrodes can be used for ascorbic acid assay within a pH range of 4,41 – 6,70, operating potential window of 0,25 – 0,4 V vs. Ag/AgCl, showing a linear range of response up to 1 mM, and a lower detection...

An Application Layer Non-Repudiation Wireless System: A Cross-Layer Approach

Adibi, Sasan 27 September 2010 (has links)
Non-repudiation techniques are to ensure any communication taking place between two or more parties will be undeniable. Therefore it is crucial to include digital signatures of the involving parties while the communication is taking place. In medical practices, involved parties include; patient(s), doctor(s), pharmacist(s), who are involved in series of visits, diagnosis, prescriptions, and possible operations. To avoid possible conflicts, deploying non-repudiation techniques help immensely. This thesis considers this issue in a wireless medium and studies the Quality of Service (QoS)/Security requirements in terms of network parameters and performance metrics. In terms of research contributions, this thesis embodies a thorough research on layered and cross-layer QoS and security schemes, in particular, featuring an adaptive Forward Error Correction (FEC) at the application layer, adapting to channel conditions. This leads to a cross layer design, which considers various QoS and security parameters export and import to and from various layers with a special focus on the application layer. The aim of this thesis is to consider a practical implementation and associated complexities of a non-repudiation system, including analytical and experimental testbeds and results. The security schemes are based on Suite-B cryptographic algorithms, including: The Elliptic Curve Diffie-Hellman (ECDH) for key agreement, the Advanced Encryption Standard - Galois/Counter Mode (AES-GCM) for encryption and authentication, the Elliptic Curve Digital Signature Algorithm (ECDSA) for digital signatures, and the Secure Hash Algorithm (SHA) for integrity. A key aspect of Suite-B is the deployment of Elliptic Curve Cryptography (ECC). The non-repudiation aspect of this thesis is based on the Suite-B’s digital signature scheme; ECDSA. The digital signature and the hashing function target the entire multimedia data (i.e., text, video, and voice) and the challenge is to offer such extensive security treatment, while guaranteeing certain Quality of Service settings. These settings include: minimum round trip delay, maximum overhead, and minimum bandwidth allocation.

Patterns of Sunscreen Application in Lifeguards, Parents and Children

Mann, Travis James 28 July 2008 (has links)
Nonmelanoma skin cancer remains the most common diagnosed cancer in the United States. Sunscreen is the most common protective method for UV exposure. For the present study, Sun Exposure and Protection Habits Measurement Study (SEPH) survey data were analyzed to determine patterns of sunscreen application in lifeguards, parents, and children, how the amount of total body coverage differs across the three participant group and the variation in coverage with respect to selected demographic characteristics for each of the 3 participant groups. Results of the study showed that children had the highest percentage of total body coverage (M=86.7, 95% CI: 82.7, 90.6) among the three groups and parents had the least (M = 68.3, 95% CI: 65.2, 71.3). No differences in the total body area covered were noted for intervention or latitude. Further research efforts are needed to determine effective intervention strategies for parents and the need for overall body coverage.
