Multi-Sensory Interaction for Blind and Visually Impaired People

This book conveyed the visual elements of artwork to the visually impaired through various sensory elements to open a new perspective for appreciating visual artwork. In addition, the technique of expressing a color code by integrating patterns, temperatures, scents, music, and vibrations was explored, and future research topics were presented. A holistic experience using multi-sensory interaction acquired by people with visual impairment was provided to convey the meaning and contents of the work through rich multi-sensory appreciation. A method that allows people with visual impairments to engage in artwork using a variety of senses, including touch, temperature, tactile pattern, and sound, helps them to appreciate artwork at a deeper level than can be achieved with hearing or touch alone. The development of such art appreciation aids for the visually impaired will ultimately improve their cultural enjoyment and strengthen their access to culture and the arts. The development of this new concept aids ultimately expands opportunities for the non-visually impaired as well as the visually impaired to enjoy works of art and breaks down the boundaries between the disabled and the non-disabled in the field of culture and arts through continuous efforts to enhance accessibility. In addition, the developed multi-sensory expression and delivery tool can be used as an educational tool to increase product and artwork accessibility and usability through multi-modal interaction. Training the multi-sensory experiences introduced in this book may lead to more vivid visual imageries or seeing with the mind’s eye

Semi-Quantum Conference Key Agreement (SQCKA)

A need in the development of secure quantum communications is the scalable extension of key distribution protocols. The greatest advantage of these protocols is the fact that its security does not rely on mathematical assumptions and can achieve perfect secrecy. In order to make these protocols scalable, has been developed the concept of Conference Key Agreements, among multiple users. In this thesis we propose a key distribution protocol among several users using a semi-quantum approach. We assume that only one of the users is equipped with quantum devices and generates quantum states, while the other users are classical, i.e., they are only equipped with a device capable of measuring or reflecting the information. This approach has the advantage of simplicity and reduced costs. We prove our proposal is secure and we present some numerical results on the lower bounds for the key rate. The security proof applies new techniques derived from some already well established work. From the practical point of view, we developed a toolkit called Qis|krypt⟩ that is able to simulate not only our protocol but also some well-known quantum key distribution protocols. The source-code is available on the following link: - https://github.com/qiskrypt/qiskrypt/.Uma das necessidades no desenvolvimento de comunicações quânticas seguras é a extensão escalável de protocolos de distribuição de chaves. A grande vantagem destes protocolos é o facto da sua segurança não depender de suposições matemáticas e poder atingir segurança perfeita. Para tornar estes protocolos escaláveis, desenvolveu-se o conceito de Acordo de Chaves de Conferência, entre múltiplos utilizadores. Nesta tese propomos um protocolo para distribuição de chaves entre vários utilizadores usando uma abordagem semi-quântica. Assumimos que apenas um dos utilizadores está equipado com dispositivos quânticos e é capaz de gerar estados quânticos, enquanto que os outros utilizadores são clássicos, isto é, estão apenas equipados com dispositivos capazes de efectuar uma medição ou refletir a informação. Esta abordagem tem a vantagem de ser mais simples e de reduzir custos. Provamos que a nossa proposta é segura e apresentamos alguns resultados numéricos sobre limites inferiores para o rácio de geração de chaves. A prova de segurança aplica novas técnicas derivadas de alguns resultados já bem estabelecidos. Do ponto de vista prático, desenvolvemos uma ferramenta chamada Qis|krypt⟩ que é capaz de simular não só o nosso protocolo como também outros protocolos distribuição de chaves bem conhecidos.

Purification of Pharmaceutical Grade Salmon-Derived Thrombin and Fibrinogen for Hemostatic Bandages

Hemorrhage due to trauma is the leading cause of preventable death among American soldiers, according the National Institute of Trauma. Uncontrollable bleeding is also seen regularly in civilian incidences of trauma and is a common major surgical complication. The human blood clotting process involves a complex cascade of tightly regulated enzymatic reactions. Two of the most important proteins in this cascade are fibrinogen and thrombin. Thrombin is an enzyme that activates fibrinogen monomers to form a polymeric fibrin network, forming the basis of a blood clot. During trauma, a state of consumptive coagulopathy, the body depletes these two proteins causing severe bleeding. A novel way to counteract hemorrhage is to supply additional thrombin and fibrinogen to the focal injury site. However, as of yet fibrinogen has proved technically challenging to produce recombinantly, and mammalian-based proteins carry the risk of pathogen transmission and immune response. Salmon-derived proteins, on the other hand, overcome both of these obstacles. DiamondStat is a novel hemostatic bandage that delivers fibrinogen and thrombin purified from salmon blood. It is a 4 x 4 inch adhesive bandage that delivers 10 mg/cm2 of fibrinogen and 90 units/cm2 of thrombin to effectively stop hemorrhage. The production of DiamondStat bandages begins with harvesting blood from salmon. Through a series of centrifugations and precipitations, prothrombin (a zymogen precursor to thrombin) and fibrinogen are extracted from the blood. Additional precipitations and filtrations further purify the fibrinogen solution to pharmaceutical-grade. The prothrombin is converted to thrombin in an immobilized snake venom catalyst column. Thrombin is then purified through an affinity column and ultrafiltration. Both thrombin and fibrinogen solutions are run through endotoxin removal columns and then sprayed onto pieces of gauze. The proteins are lyophilized onto the gauze and 2 the final bandage, which consists of fibrinogen and thrombin gauze pieces and an adhesive backing, is assembled. Bandages are sterilized via gamma irradiation and ready for use. At a capacity of 300,000 bandages per year and $800 per bandage, DiamondStat production is very profitable. It will yield an internal rate of return of 289.76$489 million. Extensive sensitivity analysis indicates that the project will be profitable in all likely scenarios. Investment in the DiamondStat processing plant is highly recommended. It is an economically viable project with the potential to save the lives of hundreds of thousands of American servicemen and women

Human-Interactive Annealing Process with Pictogram for Extracting New Scenarios for Patent Technology

The latent structure behind an observation often plays an important role in the dynamics of visible events. Such latent structure is composed of invisible events named dark events. Human-interactive annealing is developed to visualize and understand dark events. This paper presents an application of human-interactive annealing for extracting new scenarios for patent technology using the latent technology structure behind current patented technology
