The purpose of this project was to develop, using Object Oriented Development (OOD), a software tool identified as the Ada Module Description Tool (AMDT). The AMDT provides an automated way to get a module level description of Ada code. A module level description will identify packages, subprograms, objects and type declarations and relationships. This software tool also has the ability to compare Ada source code with a module level description. The comparison shall identify any object, type, subprogram, or package declared in the module level description that does not match the provided source code.The AMDT is made up of two executable programs that run on a VAX/VMS system. The Module Description Generator (MDG) generates a module level description from a set of Ada source code files. The Module Description Checker (MDC) compares a module level description to the Ada source code. Ada is the required High Order Language for the Department Of Defense. The development methodology used was basically Object Oriented Development as described in the book Software Engineerinq With-AAA by Grady Booch and the Software Standards and Procedure Manual for Object Oriented Development (SSPM-M02.04 Draft).Booch's book is a description of Object Oriented Development methodology, while the SSPM is a set of instructions and standard format to implement the methodology. The total design of the AMDT is documented in five segments. The SSPM defines a segment as the code and documentation resulting from a pass through the OOD process. From a Software Quality Engineer's point of view the AMDT would save time in not having to check module descriptions by hand. From the Software Engineer's point of view, when the code is updated a new module description can be generated easily to keep the documentation current with the code. The AMDT tool as written does not find object declarations in the code. Fortunately the effect is minor because the module descriptions needs to be edited anyway. The module description generated by the MDG may have too much information in it. The designer wants only the types, objects, and operations that aid in the understandability of the design and how it is implemented. The only checks the MDC makes are to see if an identifier on the module description is in the code. It does not check to see if there are extra items in the code that should be required in the module description. / Department of Computer Science

We now live in an information society where increasingly large volumes of data are exchanged between networked nodes in distributed systems. Recent years have seen a multitude of dierent serialization frameworks released to efficiently handle all this information while minimizing developer effort. One such format is Google Protocol Buers, which has gained additional code generation support for a wide variety of programming languages from third-party developers. Ada is a widely used programming language in safety-critical systems today. However, it lacks support for Protocol Buffers. This limits the use of Protocol Buffers at companies like Saab, where Ada is the language of choice for many systems. To amend this situation Ada code generation support for Protocol Buffers has been developed. The developed solution supports a majority of Protocol Buffers' language constructs, extensions being a notable exception. To evaluate the developed solution, an artificial benchmark was constructed and a comparison was made with GNATColl.JSON. Although the benchmark was artificial, data used by the benchmark followed the same format as an existing radar system. The benchmark showed that if serialization performance is a limiting factor for the radar system, it could potentially receive a significant speed boost from a substitution of serialization framework. Results from the benchmark reveal that Protocol Buffers is about 6 to 8 times faster in a combined serialization/deserialization performance comparison. In addition, the change of serialization format has the added benefit of reducing size of serialized objects by approximately 45%.

The Americans with Disabilities Act (ADA) has been hailed as a landmark piece of civil rights legislation and a boon to people with disabilities in the United States. Title I of the ADA specifically addresses employment discrimination toward persons with disabilities. Congressional proponents of the ADA anticipated that the statute would bring about a reversal of the high unemployment numbers among the disabled. This thesis examines the unemployment data for persons with disabilities 10 years following enactment of the ADA. It shows that the ADA has not reversed unemployment trends among persons with disabilities. This work compares the expectations of the bill's sponsors and/or advocates for improvements in employment opportunities for working aged adults with disabilities, provided for by Title I of the ADA, with the actual outcomes. This thesis highlights some the principal problems inherent with the law itself, problems that may be contributing to the ADA's inability to reverse high unemployment numbers among the disabled. This paper also addresses concerns within the US business community regarding implementation of the law. The results presented show that the ADA has not brought about the flood of litigation originally anticipated by American business, neither has it increased frivolous litigation. Data are also offered which demonstrate that compliance with the law in the form of accommodation expenses for persons with disabilities is not onerous. Finally, this study presents some of the ongoing problems with regard to discrimination against persons with disabilities in the workplace. / Master of Arts

Trypanosoma evansi is a protozoan parasite which infects a wide variety of mammalian hosts leading to the development of trypanosomiasis. Several papers have investigated the enzymatic changes in lymphocytes, important cells involved in immune responses, which are important for understanding the pathological mechanism of trypanosomiasis in animals. Among them we highlight the ectoATPases, enzymes that hydrolyze extracellular nucleotides and nucleosides of adenine. The curcumin (cur) has been associated with several beneficial effects associated with its use in animals experimentally infected with T. evansi, since this compound exhibits its properties among inflammatory and anti-parasitic effects. This study aimed to evaluate the activity of enzymes of the purinergic system in lymphocytes of rats supplemented or not with curcumin 30 days before infection with Trypanosoma evansi. Thirty-two adult male Wistar rats were divided into four groups. The uninfected control group (C) received saline intraperitoneally (IP), the infected control group (CI) received by the same route 0.2 ml of blood with 1x106 parasites and treatment with corn oil. The group pre-infection 20 (PreI20) received 20mg/kg curcumin and pre-infection group 60 (PreI60) received 60mg/kg of curcumin for 30 days prior to inoculation with T. evansi. After inoculation, the 03 treated groups continued to receive daily curcumin within 15 days before euthanasia. The NTPDase activity for both the hydrolysis of ATP to ADP increased significantly in the infected control group compared to the control group (P <0.05). The ADA activity decreased significantly in the infected control group compared to the control (P <.05). The use of curcumin at doses of 20 and 60 mg / kg for 30 days prior to infection with T.evansi reduced significantly NTPDase activity and increased significantly ADA activity in the treated groups (P <0.05). The results of this study support the evidence that the use of curcumin prior infection with T. evansi induces immunomodulatory effects, since they maintain the NTPDase activity reduced in lymphocytes, and maintains high ADA activity, favoring the response against the parasite. Thus, it is suggested that curcumin can be used as a food supplement for animals in areas where trypanosomosis is endemic. / O Trypanosoma evansi é um protozoário o qual infecta uma grande diversidade de hospedeiros mamíferos levando ao desenvolvimento da tripanossomíase. Diversos trabalhos têm investigado as alterações enzimáticas em linfócitos, importantes células envolvidas com respostas imunológicas, as quais são importantes para a compreensão do mecanismo patológico da tripanossomíase em animais. Dentre elas se destacam as NTPDases, enzimas que hidrolisam nucleotídeos e nucleosídeos extracelulares de adenina. A curcumina (Cur) tem sido relacionada com diversos efeitos benéficos associados ao seu uso em animais experimentalmente infectados com o T. evansi, uma vez que este composto apresenta dentre suas propriedades efeitos antiinflamatórios e antiparasitários. Este estudo teve por objetivo avaliar a atividade das enzimas do sistema purinérgico nos linfócitos de ratos, suplementados ou não com curcumina 30 dias antes da infecção por Trypanosoma evansi. Trinta e dois ratos Wistar adultos foram distribuídos em grupos controle não infectado (C), recebeu solução fisiológica via intraperitoneal (IP), o grupo controle infectado (CI) recebeu pela mesma via 0,2ml de sangue com 1x106 parasitas e tratamento com óleo de milho. O grupo pré-infecção 20 (PreI20) recebeu 20mg/kg de curcumina e o grupo pré-infecção 60 (PreI60) recebeu 60mg/kg de curcumina por 30 dias prévios à inoculação com T. evansi.. Após a inoculação, os 3 grupos tratados continuaram a receber a curcumina diariamente no período de 15 dias até a eutanásia. A atividade da NTPDase tanto para a hidrólise do ATP quanto do ADP aumentou significativamente no grupo CI quando comparado ao grupo controle (P<0,05). A atividade da ADA diminuiu significativamente no grupo CI em relação ao controle (P<0,05). A utilização da Curcumina nas doses de 20 e 60mg/Kg por 30 dias prévios a infecção com o T. evansi reduziu significativamente a atividade da NTPDase e aumentou significativamente a atividade da ADA nos grupos tratados (P<0,05). Os resultados deste trabalho reforçam a evidencia que o uso da curcumina previamente a infecção por T. evansi induz efeitos imunomodulatórios, pois mantêm a atividade da NTPDase nos linfócitos reduzida, e mantém alta a atividade da ADA, favorecendo a resposta contra o parasita. Desta forma, sugere-se que a curcumina possa ser utilizada como suplemento alimentar para animais em áreas onde a tripanosomose é endêmica.
