38041. Fast AES decryption
- Creator:
- Azad, Vinit
- Description:
- Due to the prevalent use of internet-enabled devices, confidentiality and privacy in communication has been more important than ever. Encryption algorithms, such as AES and RSA, are used to ensure the security and privacy of such communications. However, as computers get computationally powerful, more complex encryption algorithms are needed to avoid brute force attacks. This complexity in the algorithms also means that encryption and decryption of messages using these algorithms can be slow. To avoid this decrease in speed, many optimizations have been proposed to make these complex algorithms perform much faster. Emilia Käsper and Peter Schwabe proposed one such optimization to AES in their paper “Faster and Timing-Attack Resistant AES-GCM.” They describe a fast constant-time AES encryption algorithm, which is also immune from cache-timing attacks, using Intel’s SSE instructions. This paper focuses on the study of Käsper and Schwabe’s proposal and implements a fast constant-time AES decryption algorithm that can work with their encryption algorithm. The paper concludes that while the decryption algorithm is slower than the encryption algorithm proposed by Käsper and Schwabe, it is about 3 times faster than the standard decryption implementation such as OpenSSL. Therefore, this fast decryption algorithm paired with Käsper and Schwabe’s fast encryption algorithm can provide users a complete AES package that can be used in applications that require fast encryptions and decryption along with protection against timing attacks.

- Description:
- An Afro-Eurocentric English Curriculum for Congolese Classrooms is a culturally responsive teaching Afrocentric curriculum rich in content and has been designed for active engagement and participation (Akoto, 1994; Ani, 1994; Lee, 1994; Murrell, 1993. 1997; Roberson, 1996). This multicultural curriculum blends both the Afrocentric culture and the Eurocentric culture, and uses modern approaches that utilize student-centered methodology to sustain students in continual learning modes inside and outside their classrooms. A well balanced education fosters political stability, tolerance, and better governance. In short, a good English education allows Congolese people to empower themselves to improve their lives as citizens of both their country and the world and communicate in English as a common language.

- Description:
- The integration of students identified with Emotional Behavior Disorders (EBD) is increasing in the general education setting. Teachers are in need of the necessary skills and supports to help them deliver adequate instruction to these students. Studies show that teachers' attitudes and self-perceptions of competencies are based on the knowledge they have or do not have when dealing with students identified with EBD. Clearly, to provide effective instruction to students with EBD in the general education setting, substantial knowledge in research-based strategies is vital to delivering instruction and fostering the success of the student (Shapiro, Miller, Sawka, Gardill, & Handler, 1999). The information for this project was obtained through a review of books, periodicals, Internet websites, discussions with other teachers in the general or special education field, and personal experiences of the authors who work with students in both the general and special education classroom and are familiar with classroom instruction for students with EBD in the general education setting. In addition, information was also obtained from district personnel and administration through the use of interviews. School-based staff development is a highly effective form oftraining for general education teachers. The information gained from research-based strategies and peer discussion proved to be a valuable tool for general education teachers who currently instruct students diagnosed with EBD.

- Description:
- There has been an obvious drop in the amount of Latin students graduating in comparison to those of white students. They have been losing both their interest in studying and identity of who they are as a bilingual, Spanish speaking individual. Students who are fluent in Spanish have stopped challenging themselves by taking Spanish for Spanish speakers or AP Spanish courses; they have instead taken a regular Spanish course which has been designed for students who are learning the language for the first time. This is considered a waste of time and no new knowledge is being given onto the students. Sources of Data This study incorporates multiple methods for data collection including students and interviews, and compilation of student academic records. Researcher conducted semi-structured interviews gathering qualitative data. Interviews were directed individually to six Latinas second language learner students. They were all first and second generation students of Mexican descent in their junior of senior year of high school. This study was conducted over the period of one year. Conclusions Reached If the students are given a reason to be proud of their culture and background, they will stand through all they must to also make a change. The students will be shown images of well-known athletes, actresses, and artists who are also from the same background as them. The student will be able to identify themselves with one of the given examples and it will motivate the student to become more engaged in his or her future. This will persuade the student onto taking AP Spanish courses and pushing their self to a challenging, more promising road onto their future.

- Description:
- The purpose of this Project is to develop and implement the enhanced features of Internet Interpreter Scheduling System as mobile application in healthcare domain and made it synchronize with the existing web application as well. This project includes the development of mobile application in Asp.Net and maintaining a global database for both web and mobile application by accessing through the I2S2 web services. I2S2 mobile application is proposed to run efficiently on HTC windows mobile phone. Existing Internet Interpreter Scheduling System has three types of users. They are Agency Platform, Requester/Provider Platform and Interpreter Platform Users. Interpreters are going to get appointments scheduled by agency and requesters into the schedule folder of the mobile application by connecting to web services based on day, week and month calendar format. Uncovered appointments can be placed into public folder of Interpreters. Therefore, even interpreters can view the appointments in “View Available Appointments” folder and accept the appointments based on their availability. Agency will keep some of the interpreter appointments into the Interpreter folder of the Interpreter.Intended Interpreter can accept or reject appointments in interpreter folder based on their availability. After Time Finish Appointments authorized with signature and get synchronize with database. Appointments rejected by the interpreter will be scheduled by the agency to another interpreter. Modules like Schedule, My Folder, Available Appointments, View Details, Time Finish and Sync were implemented in the Internet Interpreter Scheduling System as per the customer requirements. Internet Interpreter Scheduling System application can be entered using Application Name, User Name, and Password as login credentials. System provides Password facility to ensure validity of user. Scheduling System mobile application can be login in both online or offline modes. If the interpreter is not having the proper internet connectivity or not in the network coverage area, he can login into the system in offline mode. Mobile application transfers data and appointment status to the SQL Server Enterprise database using web service after mobile gets internet connectivity. This project was developed using the technologies like Asp.Net, C#, Microsoft Windows Mobile API, Microsoft SQL Server 2008 as Database, XML and Web Services.

- Description:
- Human Immunodeficiency Virus (HIV) and the subsequent acquisition of Acquired Immunodeficiency Syndrome (AIDS) continues to affect millions of lives around the world with no effective vaccine available. Current antiretroviral treatments are effective at repressing the infection but do not cure it. The high mutation rate of HIV has made it difficult to design drugs against, however, a new gene therapy method may provide a better alternative for HIV treatment. By combining multiple highly effective anti-HIV genes into a single gene therapy vector that can be transduced into cells, a one-time treatment may provide lifelong HIV resistance. This experiment utilizes a replication-incompetent lentiviral vector encoding for three highly effective anti-HIV genes which target separate stages of the HIV lifecycle: a CCR5 shRNA (pre-entry), a chimeric TRIM5α protein (post-entry/pre-integration) and a TAR decoy (post-integration). When challenged with HIV, cultured and primary CD34+ hematopoietic progenitor cell (HPC)-derived macrophages transduced with this triple combination vector showed potent inhibition of viral pre-integration infection. The generation of mutant viral particles was blocked as well after long-term evaluation of challenged cells. When the combination anti-HIV lentiviral vector was tested in vivo in mice engineered to have elements of the human immune system, the vector proved safe and effective at inhibiting HIV infection. It was then determined that the vector must be produced in large amounts for clinical applications. During my internship at the UC Davis Institute for Regenitive Cures, I manufactured this anti-HIV lentiviral vector at a titer of 109 viral particles per mL. In addition to providing cures for infectious diseases, such as HIV, gene therapy may also provide a permanent treatment for genetic diseases such as epidermolysis bullosa (EB), through the derivation and subsequent manipulation of patient-derived induced pluripotent stem cells (iPSCs). By converting a patient’s own cells containing a genetic defect into iPSCs, the genetic defect can be corrected and then the pluripotent iPSCs can then be differentiated into any cell type in the body and grafted back into the patient. In order to derive these iPSCs, the patient’s cells must be transduced with a lentiviral vector containing genes that “reprogram” these cells back to a pluripotent state. In my project, I manufactured a single DNA vector containing the four genes: Oct4, Sox2, c-Myc and Klf4 which would, once inside a cell, cause the cell to be “reprogrammed” to a pluripotent state.

- Description:
- Current trends in healthcare related to renewed focus on quality and safety are leading to dramatic changes in nursing education. Although first published in 1984, the work of nursing theorist Patricia Benner clearly describes the manner in which nurses develop and progress from one skill level to the next (Benner, 2001). This aligns with current evidence based practice (EBP) in nursing education. Knowledge of theory is not enough. Learning technical nursing skills in isolation is not enough. Benner posited that nurses learn by exposure to the environment in which they will practice. To that end, and in light of current EBP in education, this project creates new skills lab curriculum for first semester nursing education at California State University, Sacramento.

- Description:
- The use of restraints on individuals with special needs has been increasing over the past decade, especially among law enforcement agencies. Even though, improper use of restraints can lead to severe harm and even death there are no federal guidelines on the proper use of restraints in school systems. However, there are organizations, such as the Council for Exceptional Children (CEC), that propose guidelines that agencies can follow. This study describes the current controversies, policies, and use/abuse of restraints by law enforcement agencies. The aim of this study is to develop awareness and to train law enforcement agencies on the use of restraints with individuals with special need. The training provided to a select group of police officers, focused on understanding the importance of restraining restraints, naming the different types of restraints, identifying characteristics of different disabilities, learning de-escalation strategies, and how to employ safe “restraints.”

- Description:
- Aluminum injection molds, primarily used in the past for prototypes are being investigated for use as production molds with the advent of a new generation of aluminum materials specifically tailored for this application. This project investigates the effects of using aluminum tooling while comparing the importance of other contributing factors in molding performance through the use of Moldflow software and Taguchi methods. The large number of variables studied, 13 at three different levels, contributed to some interesting results that were not seen on other published studies with smaller numbers of variables. The main focus, the mold material was found, not surprisingly, to be an important contributor in molding performance. However, unexpectedly the aluminum tooling in this instance was found to perform poorer than steel while beryllium-copper was found to be far superior to both. Factors such as melt temperature and mold temperature were important contributors. Other variables that were the focus of experiments with fewer variables, such as waterline geometries were found to be of little importance in comparison.

- Description:
- A review of literature demonstrated the national significance of John Muir’s accomplishments to the conservation movement in the United State as well as the significance of the home site and ranch. Student field trips to the John Muir National Historic Site were conducted by focusing on a Victorian Home tour where John Muir lived and worked. The National Park Service (NPS) believed home tours overlooked key opportunities to tell the larger story of John Muir’s values and accomplishments, use the natural and cultural resources of the ranch, and demonstrate the relevance of both John Muir and the historic site to the needs of contemporary students. Local area teachers advised the historic site interpretive staff of their interest in bringing classes on multiple field trips during the school year if the staff expanded the range of activities and experiences available at the site. This project examined John Muir’s life, his connection to the Strentzel-Muir Ranch and the natural and cultural resources of the site itself. A field trip curriculum guide is provided as the primary tool to expand existing thematic interpretation and education opportunities on the site. Information was gathered through a review of literature on the following topics: 1) significance of the site and its development as a national park; 2) how activities that occurred at the Strentzel-Muir Ranch helped to define and illustrate early California agricultural history and urbanization of the Alhambra Valley. A one-day teacher orientation workshop, numerous interviews with NPS site staff and literature reviews contributed to the creation of the total project. The Field Trip Curriculum Guide developed through this project presents a series of guided tours, lessons, projects and field studies for 1) NPS interpretive staff and volunteers to use as tools for orientation to John Muir and the historic site, 2) creating opportunities to increase the range of age groups that can be served at the site through the use of expanded interpretive programming and 3) teachers to apply before and after the site visit and within and outside of the classroom.

- Description:
- This was an exploratory qualitative study of practitioners’ perceptions of relapse. The data collected was through voluntary individual interviews of eleven practitioners. The data was coded and overall themes emerged. The interviewees’ basic definition of recovery was “getting clean.” They discussed relapse as often, but not always, part of recovery. Opinions of 12-Step programs varied from viewing it as treatment, a tool, or support. Humiliation as a form of treatment was frowned upon. Humiliation was equated with shame and guilt and interviewees discussed its unintended consequences and how humiliation may potentially act as a motivator or a barrier to recovery. Furthermore, based upon the level of credential, there was a perceived difference regarding how personally or professionally questions were answered.

38053. Woodwind quintet #1
- Creator:
- Salvo, Victor Vincent
- Description:
- My idea in this, my first woodwind quintet, was to compose five movements or vignettes that would feature a different instrument in each of its sections. While the five instruments comprising a woodwind quintet blend well together, each has its own distinctive voice, which is explored along with each instrument’s unique personality and range. It has always intrigued me that musical instruments, perhaps especially the winds, have the unique ability, without human voice or expression, to elicit a wide range of moods and emotions. Humor and tragedy, darkness and light, heaviness and buoyancy, love, fear, pathos and much more can quite readily be evoked by any of these instruments depending upon turn of phrase, harmony, texture, dynamics, rhythm and the myriad possibilities of the interplay between all of these elements and between the instruments themselves. The first, third and fifth movements, featuring, respectively, flute, clarinet, and bassoon, employ brisker tempos with more upbeat and occasionally humorous melodies while the v second and fourth movements, featuring, respectively, the oboe and horn, contain more reflective melodies at slower tempos. In this way do I hope to communicate, or frame, at least some of the feelings, positive and otherwise, which we all experience at one time or another. Each movement has at least one small solo section for the featured instrument as a contrast with the full ensemble sound that gets ample exposure. Major and minor modalities are used freely and interchangeably, and while key signatures are not used, none of the movements are atonal and all contain key centers, which serve as harmonic anchors. One of my goals in these vignettes is to create a harmonic background that is not entirely literal and that contains a certain element of ambiguity. This technique is, for me, analogous to using pastels as opposed to brighter, more defined colors in a painting, and serves as a binding agent, which unites all five movements with regard to harmonic accompaniment. In order to make more possible the playing of the entire quintet in one concert, I have limited the duration of this piece; it can be performed in less than eighteen minutes. As such, there is very little development in each vignette. Rather, I have generally constructed for each movement an introduction, a statement of themes (usually two per movement), connecting or transition sections, a re-statement of the primary theme and a coda as a punctuation mark. To provide variety, each of these sections varies in length vi and the solo sections come in different places from movement to movement, at times doubling as the introduction, at other times acting as a respite from the concerti sections.

- Adaptive Delta Pulse Code Modulation is a well known encoding scheme used for speech processing. This project focuses on the simplification in the technique so that the hardware complexity can be reduced for the portable speech recording devices. The reduce hardware complexity also provides added advantages like low power consumption and portability. The simulation of the suggested simplification in the algorithm is done using the MATLAB tool. This project focuses on .wav format audio file and encoding and decoding using ADPCM technique is done. This project provides practical comparison by comparing the actual audio file with decoded audio file and their respective graphical representations. The hardware implementation of speech recording and playback is done using Atmel STK500 kit and ATMEGA32 microcontroller. The ADC and PWM schemes are used to interface analog signals to the core digital hardware. To conclude, this project tries to provide insight of algorithm and hardware that can be used for the portable speech recording playback devices.

- Creating activities that challenge toddlers has been difficult for teachers to develop. California has designed foundations as a resource for preschool teachers to construct and implement activities that assist children in social-emotional development, language and literacy, English-language development and mathematics (California Department of Education, 2008). Other resources are the approach to use in the development of such curricula such as a theme-based and developmentally appropriate practice (Katz & Chard, 2000). However, these resources are often not geared toward children younger than three years of age. The current project is designed to assist toddler teachers in the preparation of developmentally appropriate activities, which are linked, to the California Preschool Learning Foundations (California Department of Education, 2008). To develop the curriculum, the scholarly literature and California Preschool Foundations were consulted. Vygotsky’s (1989) theoretical ideas of the Zone of Proximal Development and the importance of social interactions in cognitive development served as the basis for the project. The review of literature focused on the following areas: developmentally appropriate practices (Copple & Bredekamp, 2009), theme-based curricula (Katz & Chard, 2000), Reggio Emilia approach (New, 2003), the preschool foundations (California Department of Education, 2008), and social competence skills (Brownell, 1990). The classroom should include a well-rounded environment that fosters the development of young children. The resource materials in this theme-based curriculum will comprise of challenging lesson plans that are in line with the current research on the best practices in teaching young children and that compliment the California preschool learning foundations (California Department of Education, 2008).

- Description:
- The Hmong are a distinct ethnic group from Laos, Thailand, Vietnam, and China. During the Vietnam War, many Hmong in Laos assisted the Central Intelligence Agency in the United States’ “Secret War” operations in Laos against communist forces. After the fall of Laos to communists, many Hmong refugees migrated to the United States. Sacramento is home to the third largest Hmong population in the nation. The Sacramento Hmong community continues to grow but not much is known about their life experiences. The goal of this project is to record the life histories of five Hmong Americans who came to the United States as refugees. Although the Hmong have been the subject of increasing scholarly studies, little has been done in terms of oral histories on the Hmong community. The project employed oral history methodology to record the personal histories of five individuals with regards to their life experiences in Laos, Thailand, and the United States. The interviews were digitally recorded. Three of the interviews were fully transcribed, and all of the interview materials were donated to the University Special Collections and Archives at Sacramento State.

- Description:
- With the amount of wireless impact in today’s society, filter design is a very important and integral aspect of modern communication systems. The main purpose of filtering is to improve the signal to noise ratio, SNR, , which describes how much noise has contaminated the original signal. By filtering the noise, the signal to noise ratio is increased, and the signal becomes easier to receive and comprehend. This particular filter, designed and fabricated in this project, is targeted for space communication applications. It will demonstrate optimal performance at temperature extremes and zero pressure environments. The design will also exhibit the highest form of reliability due to its application. The design must be so reliable that it will operate for a minimum of 17 years with the smallest probability of failure; less than 1%. The particular kind of filter is a band pass filter, which will be designed using lumped elements using a capacitively coupled pi resonator filter structure. Once the filter is realized and fabricated, the performance of the filter will be evaluated against the specifications it was designed to meet.
