Low-Latency Energy-Recovery Circuitry

Low-Latency Energy-Recovery Circuitry by Jerry C. Kao Chair: Marios C. Papaefthymiou Voltage scaling has diminished with each advancement in process technologies, making power dissipation one of the primary design considerations for modern digital systems across all market segments. This dissertation describes a novel charge-recovery logic family and a resonant-clocked dynamic logic that utilize energy-recovery techniques to recycle charge from the system, effectively reducing dynamic power dissipation. We propose a novel charge-recovery logic, called Enhanced Boost Logic, which achieves high efficiency and high performance operation through the use of aggressive voltage scaling, gate overdrive, and charge-recovery techniques. Fabricated using a 0. 13μm technology with a 3nH on-chip inductor, a 14-tap 8-bit FIR filter implemented using Enhanced Boost Logic achieves operating frequency up to 600MHz with only 1.5 cycles of latency overhead compared to a static CMOS implementation. At its natural frequency of 466MHz, the FIR dissipates 39.1mW. With a figure of merit equal to 93.6nW/MHZ/Tap/InBit/CoeffBit, it achieves 29% improvement compared to previously reported FIR filter test-chips with equal or greater sampling rate than our design at its 466MHz resonant point. We also propose a dynamic logic family, call Dynamic Evaluation Static Latch,
SPACECRAFT FAULT ANALYSIS USING DATA MINING TECHNIQUES

In this paper, we propose a new approach to spacecraft fault analysis based on an appropriate combination of data mining techniques. More precisely, we first transform the time series data representing the spacecraft parameters into points in a 9-dimension feature space, then we apply the K-means clustering algorithm so as to identify the typical parameter patterns. Finally, we adopt the Apriori algorithm to derive interesting association rules between typical patterns and the occurrence of spacecraft anomalies. We show the successful application of the found association rules to a benchmarking set of housekeeping telemetries (HKTMs).
An Analysis of the Impact of Total Quality Management on Employees

Abstract : Ireland Army Community Hospital (IACH) began to transition from a traditionally organized facility to a nontraditionally organized facility under the auspices of TQM in 1992. Traditional departments were dissolved and reorganized under functional teams who reported to an executive team. The teams were designed to be self managed and empowered to improve patient care processes. The results of the study indicate that the TQM program is not having a positive impact on the employees' attitude. There were few statistically significant (p<.01) differences in the bivariate and multivariate analyses. The bivariate analysis identified only three (of thirteen) statistically significant (p<.05) items. These results should not be an indictment of the TQM program but an indication of the direction of the current program. The implementation of a TQM program can take years to be fully realized and other internal and external forces have bearing on the impact of the implementation of TQM. IACH can pursue several options ranging from staying with the status quo, dedicating more resources to the program, or reorganizing the current organizational structure.
DIFFERENCES IN INTERLEUKIN 18 LEVELS IN DIABETIC NEPHROPATHY AND NON-DIABETIC NEPHROPATHY PATIENTS

Background: Diabetic nephropathy is a common complication in diabetics. In this disease damage to the kidney filter or known as glomerulus. Therefore causing glomerular damage, the amount of blood protein is excreted into the urine abnormally. IL-18 is a proinflammatory cytokine produced from activated macrophages, serum IL-18 levels are produced to increase in patients with diabetic nephropathy. IL-18 which affects the production of other proinflammatory cytokines, endothelial apoptosis, ICAM-1 certification enhancement. Thus, IL-18 may be an important factor not only in the process of atherosclerosis but also in the development of diabetic nephropathy. Aim: Knowing the IL-18 levels in diabetic nephropathy and non-diabetic nephropathy patients. Methods: The study was conducted using the Cross Section method. This study took blood samples from 60 diabetic patients, of which 30 patients with nephropathy and 30 patients with type 2 diabetes. Then took 5 ml of blood from a vein and assessed serum IL-18 levels in all patients. Results: The study was conducted for 3 months, 41 men (68.3%) 19 women (37.1%). Serum IL-18 levels were significantly increased in patients with diabetic nephropathy compared with patients with type 2 diabetes (362.7 vs 55.7 pg / ml, p <0.001) Conclusions: Increased IL-18 levels in diabetic nephropathy patients can be used as prognostic events for diabetic nephropathy.

Nonlinear dynamics in microelectromechanical systems

This study is suggested by the growing attention, both from a practical and a theoretical point of view, toward the nonlinear behaviour of microelectromechanical systems (MEMS). The dissertation considers two different case-studies. In the first case-study, the nonlinear dynamics of a MEMS device subjected to a constant axial load, electrostatically and electrodynamically actuated and with a very shallow arched initial shape simulating the imperfections due to the microfabrication process are analyzed. The aim is that of illustrating the nonlinear phenomena which arise due to the coupling of mechanical and electrical nonlinearities and discussing their usefulness for the engineering design of the microstructure. An accurate single degree of freedom reduced-order model is derived. The device is investigated in a neighbourhood of the bifurcation from a single to a double potential well. Systematic numerical simulations are performed by the combined use of frequency response diagram, behaviour chart, attractor-basins phase portraits. The main features of the nonlinear dynamics are investigated in detail, as the non-resonant and resonant oscillations with softening behaviour, the coexistence of several robust attractors leading to a considerable versatility of behaviour, the safe basin erosion. In the second case-study, starting from the experimental data of dynamic pull-in due to a frequency-sweeping process in a capacitive accelerometer, a dynamical integrity analysis is performed. The loss of dynamical integrity is investigated by curves of constant percentage of integrity factor. It is found that these curves follow exactly the experimental data and succeed in Doctoral School on Engineering Sciences Università Politecnica delle Marche interpreting the existence of disturbances. The theoretical curves of disappearance of the attractors, instead, represent the limit when disturbances are absent, which never occurs in practice. Also, the obtained behaviour chart can serve as a design guideline in order to ensure safety of the device.
Development of Pre-service Teachers’ Assessment Literacy in Assessment Education

This qualitative study explored how current assessment education courses offered by American academy-based teacher education programs prepare pre-service teachers from China for using real-time classroom assessment. Following an instrumental case study approach, the study collected data from two individual Chinese international students via interview. Analysis of the data suggested that the current assessment-related courses offered by American teacher education program were perceived by Chinese pre-service teachers as useful and helpful in improving their assessment-related knowledge and skills. Principal contributors to the effectiveness of these courses include their great emphasis on learner-centered teaching belief and the content-oriented development appropriate assessment strategies. However, more cultural responsive and process-based teaching methodologies should be integrated in assessment courses in order to better fit international students’ assessment learning needs.

Biosurfactant production by Trichoderma sp. MK116452 and its possible application in oil recovery

Surfactants are amphiphatic compounds containing both hydrophilic and hydrophobic groups, which are capable of lowering surface or interfacial tension. Considering the advantages of using biosurfactants produced by microorganisms, the aim of this study was to develop and characterise a biosurfactant produced by Trichoderma sp. MK116452 isolated from Seri Cermin filling station, Brunei Darussalam, and to examine its potential application in microbial enhanced oil recovery (MEOR). The microorganism was cultured in a minimal salt medium containing 1% crude oil as a carbon source and a cell-free culture broth was used to screen its efficiency in producing biosurfactants. Characterisation of the biosurfactant showed the presence of glycosides and fatty acids, suggesting its glycolipidic nature. The isolated biosurfactant showed no toxicity to the micro-crustacean Artemia salina or to red bean ( Vigna angularis ). The extracted biosurfactant was effective at recovering up to 60% of crude oil from sand using the sand pack column method, which is similar to the recovery rate for a chemical surfactant (SDS) (65%). These findings highlight the potential use of Trichoderma sp. MK116452 biosurfactant in the oil industry.
The Hypoglycaemic, Antihyperlipidemic and Antioxidative Effects of Anacardium Occidentale Methanolic Nut Extract in Streptozotocin-Induced Diabetic Male Wistar Rats

Background: This research work investigated the antidiabetic, anti-hyperlipidemic, and antioxidative effects of Anacardium occidentale methanolic nut extract in Streptozotocin (STZ)-induced diabetic Wistar rats. Methods: Forty (40) Wistar rats weighing 250±30g were randomly divided into five groups of 8 rats each. Group 1 served as the control; Group 2-5 were induced with diabetes with a single dose of 50mg/kg bw of streptozotocin intraperitoneally. After diabetes induction, Group 2 served as the STZ-only group, Groups 3 and 4 were administered 100mg/kg bw and 200mg/kg bw p.o Anacardium occidentale nut extract, respectively, while Group 5 was administered 2mg/kg bw of glimepiride as a reference drug for a period of 4 weeks. Food and water intake were monitored daily, body weight, and blood glucose levels weekly throughout the experiment. On day 29, the animals were sacrificed, and blood samples were collected through cardiac puncture for biochemical studies. Results: Administration of the nut extract significantly (p<0.05) increased the food intake and body weight of diabetic treated rats, fasting blood glucose level and oral glucose tolerance test (OGTT) decreased significantly (p<0.05) in treated rats. On lipid profile, administration of nut extract significantly decreased (p<0.05) triglyceride, low-density lipoprotein, total cholesterol, and very-low-density lipoprotein concentrations while it significantly increases (p<0.05) the high-density lipoprotein. Anacardium occidentale nut extract caused significantly (p<0.05) increases in SOD, GPx, GSH, and CAT levels with a decrease MDA level in diabetic treated rats. Markers of liver and kidney functions were also improved in diabetic treated rats.Conclusion: Treatment with Anacardium occidentale methanolic nut extract has hypoglycemic, hypolipidemic, and hepato-protective effects in diabetic rats. It also alleviates oxidative stress activity and restoration of markers of kidney function, and may be useful as alternative therapy in the management of diabetes and its related complications.
Black, White, Brown, Green, and Fordice: The Flavor of Higher Education in Louisiana and Mississippi

Black, White, Brown, Green, and Fordice: The Flavor of Higher Education in Louisiana and Mississippi chronicles the higher education desegregation sagas in Louisiana and Mississippi. The Article specifically compares the histories of the higher education desegregation lawsuits in the two states and their subsequent experiences and progress under Settlement Agreements. The statistical populations of many universities in both states are still largely identifiable as "white" or "black," and so the Article poses questions not only respecting the implementation of United States v. Fordice in both states, but also respecting the value, desirability, or possibility of the "integrative ideal" converting "black schools" and "white schools" to "just schools. "

Indication and Identification of Dengue and Chikungunya Viruses in Aedes spp. Mosquitoes Captured in Central America

The purpose of study was to isolate arboviruses from mosquitoes of different species in the cell culture and to identify them by using molecular and immunochemical techniques.Materials and methods. Viruses were isolated in C6/36 cell cultures. The pathogens were identified by using enzyme-linked immunosorbent assay (ELISA) kits for detection of antigens of dengue, Chikungunya, West Nile and Sindbis viruses as well as the reverse transcription polymerase chain reaction (RT-PCR) with specific primers and Sanger sequencing.Results. A total of 102 mosquitoes belonging to three genera, Culex spp, Culiseta spp. , Aedes spp. , were studied. Mosquitoes of each species or genus were divided into pools, each containing 4–5 mosquitoes. The study of suspensions of only 2 mosquito pools obtained from Aedes aegypti and Aedes albopictus, starting from the 3rd passage, showed changes in the C6/36 cell monolayer. Starting from the 4th passage, an antigen of Chikungunya virus was detected using ELISA test in the suspension obtained from the Aedes albopictus pool. Dengue virus was detected in the 5th passage from the materials obtained from the Aedes aegypti pool. Thus, antigens of the Chikungunya and dengue viruses were detected only in 2 of 23 examined pools of mosquitoes of different genera. Materials of the 5th passage were analyzed by RT-PCR with specific primers for dengue and Chikungunya viruses. It was confirmed that the isolate obtained from Aedes albopictus mosquitoes contained RNA of the Chikungunya virus and corresponded to the East/Central/South African genotype, while the isolate obtained from Aedes aegypti mosquitoes contained RNA of the dengue type 2 virus.Conclusion. The obtained nucleotide sequences of the Chikungunya virus were deposited in the GenBank international database under accession numbers MN271691 and MN271692.
AIRFOIL PERFORMANCE IN HEAVY RAIN

In recent years microbursts have been implicated in several major aviation accidents. Since microbursts are often accompanied by heavy rainfall, an interest in airfoil performance in rain has arisen. As raindrops strike the leading edge of an airfoil, small droplets are splashed back into the airflow field, and an uneven water film forms on the airfoil surface. Both phenomena have been hypothesized to contribute to a degradation of airfoil performance in rain that may be manifested as a decrease in lift, an increase in drag, and premature stall. The splashed-back droplets are accelerated by the airflow field. Thus droplet drag acts as a momentum sink to deenergize the boundary layer, while the uneven water film effectively roughens the airfoil surface. A numerical, two-way momentum coupled, two-phase flow scheme for the evaluation of the effect of splashed-back droplets on a NACA 64-210 airfoil section in cruise configuration is described. A thin-layer Navier-Stokes computational fluid dynamics code is coupled with a Lagrangian particle tracking scheme to determine the two-phase flow field in an iterative manner. Noninteracting, nondeforming, and nonevaporating spherical particles representing statistical distributions of raindrops are tracked through the curvilinear body-fitted grid used by the airflow code. A simple model is used to simulate raindrop impacts and the resulting splashback on the airfoil surface. Results are compared with wind tunnel test results.
