The project focuses on developing multicore processor designs for hard real-time embedded systems and techniques to guarantee the analyzability and timing predictability of every feature provided by the processor.

Parkinson's Disease is a neurodegenerative and intensifying disorder. The symptoms of this disease are classified into two types - motor and non-motor symptoms. Some of the motor symptoms are instability in posture, bradykinesia, tremor, etc while on the other hand, the non-motor symptoms are changes in body odor, sleep disorders, difficulty in swallowing and depression. The intensity of these symptoms differs from person to person. Amongst these two types of symptoms, non-motor symptoms are identifiable at an early stage. Hence detection of these symptoms helps in recognizing whether a person has Parkinson's Disease at an early stage. Patients diagnosed with Parkinson's Disease give out a distinguishable musky smell. The paper describes a non-intrusive and definite method for detecting Parkinson's disease through an individual's smell signatures. VOC sensors which determine the components in sweat were used to achieve this objective. The sensors were interfaced with Arduino UNO, which in turn gave the values of the different components of sweat in the Arduino programming software. The values of the various components of sweat obtained from people with Parkinson's Disease and healthy individuals is compared. This comparison is used to determine whether that person is suffering from the disease. The proposed system can be utilized by clinicians in their annual health check-ups without the usage of exorbitant diagnostic tools.

Quality assurance in general and testing in particular remains as an unsolved problem in product line engineering. It is unclear, from an economic point of view, whether one should test each product line member separately or test just product-specific parts and compose them with tested core assets from family engineering. While the former strategy introduces redundancy in testing, the latter strategy is also more difficult because of genericity. Ideally, we need to carefully calculate cost-benefits of both cases and define a test strategy accordingly. Currently, there is no economic model for testing in the context of product lines. Thus, we introduce an initial economic model, and then perform Monte-Carlo simulations to calculate cost-benefit of the two test strategies. For the Testo product line of climate and flue gas measurement devices, the results showed that, using an infrastructure-focused test strategy, on average a cost saving of 13% can be expected with 87% certainty.

Family context has been shown through empirical studies to be a central determinant in the mental health of youth throughout the past decade. In this analysis we examine the association between attachment, parental depression, divorce, family climate, and siblings, and the risk of adolescent depression. Conclusions are made regarding the complex nature of family situations, and specific improvements and suggestions for future studies of the effects of family situation on adolescent depression.

A Shore Protection Master Plan (SPMP) for the Nile Delta Shoreline, extending from 30 kms west of the city of Alexandria (Arab Republic of Egypt) to 30 kms east of Port Said, is developed and reported. The SPMP was developed in three stages: (1) collection and analysis of relevant data to identify existing and future coastal problems and limits of needed shore protection, (2) development of shore protection alternatives with costs and economic evaluations, and (3) detailed design and technical specifications for the selected shore protection schemes along the SPMP zone. This paper summarizes Tetra Tech, Inc./Honeywell work and achievements on this project while under contract with the Egyptian Shore Protection Authority (SPA). The SPMP considered the Egyptian Government and the SPA national needs to the year 2000.

This paper presents a new approach to input design for closed-loop identification. The idea is to maximize the trace of the Fisher information matrix associated with the plant model, while enforcing explicit constraints on both inputs and outputs. The result is the richest possible excitation signal for which the operation of a running closed-loop system remains within acceptable bounds. The function to be maximized is a convex quadratic. A Moving Horizon Predictive (MHP) framework is used to solve the input design problem at each sample time. The method can be combined with a fixed model variable regressor technique to estimate time delays. The suggested technique is implemented and used to identify machine-directional processes in an industrial paper machine.

• Lemon eucalyptus (lemon-scented gum ) specimens were hydrothermally treated. • Microstructures of the wood-derived natural composite material specimens were observed. • Torsion tests on specimens with and without hydrothermal treatment were conducted. • Compression tests on specimens before and after hydrothermal treatment were performed. • Fracture surface morphology and mechanical property changes were found due to the treatment. In this work, fracture surface morphology and mechanical property of the natural composite material derived from lemon eucalyptus (or lemon-scented gum) tree were investigated. Microstructure and fracture surface of the wood specimens were examined. Mechanical tests under torsion and compression were conducted. The modulus of elasticity (Young’s modulus) and shear modulus (modulus of rigidity) were determined. The effect of hydrothermal treatment (HTT) on the specimens was studied. It was found that both shear and compressive strengths of the natural composite material decreased after HTT at 200 °C. Increasing the treatment time led to more decrease in compressive strength. The fracture surface observation reveals intensive fiber formation from the hemicellulose degradation. Hydrothermal treatment is valuable for developing energy-saving and sustainable wood fiber production processes.

This paper focuses on universal compression of a piecewise stationary source using sequential change detection algorithms. The change detection algorithms that we have considered assume minimal knowledge of the source and make use of universal estimators of entropy. Here, data in each segment is characterized either by an I.I.D. random process or a first order Markov process. Simulation study of a modified sequential change detection test proposed by Jacob and Bansal [1] is carried out. Next, an algorithm to effectively compress a piece-wise stationary sequence using such change detection algorithms is proposed. Overall compression efficiency achieved with Page's Cumulative Sum (CUSUM) test and the modified change detection test proposed in [1] (JB-Page test) as part of the change detection schemes, are compared. Further, when JB-Page test is used for change detection, four different compression algorithms, namely, Lempel Ziv Welch (LZW), Lempel Ziv (LZ78), Burrows Wheeler Transform (BWT) and Context Tree Weighting (CTW) algorithms are compared based on their impact on overall compression.

The Port of Long Beach, in cooperation with the Port of Los Angeles and the Corps of Engineers, has been working on the development of a Master Plan for the San Pedro Bay area. This Master Plan, nicknamed the "2020 Plan", is intended to project the Port's land and channel requirements through the year 2020. Any landfill expansion program would be implemented in phases throughout the life of the Master Plan. The initial phases of such a plan would greatly limit the ability of the Port to revise the future configuration of landfill phases, making it important for the Port to determine a final landfill configuration before implementing the early phases. In developing the 2020 Plan, the Port projected a need for approximately 2,600 acres of additional land. In attempting to turn this 2,600 acre figure into a landfill scheme, the controlling agencies had to take a number of factors into consideration, including (1) water quality and tidal circulation; (2) potential ship motion problems; (3) additional berths required for future development; (4) land and waterside transportation corridors required; (5) availability of dredge material for creating the land; (6) available areas for creating landfills; (7) efficiency of land usage in various configurations; (8) types of ships anticipated to use the new landfills; (9) types of terminals anticipated to be located on the new landfills. The Port of Long Beach developed two basic schemes which addressed the requirements listed above. In either case, the landfill configuration for the Port of Los Angeles remained the same. The first scheme (called the island scheme, Figure 1) had the advantage of more closely matching the proposed Port of Los Angeles development. Water quality and tidal circulation would be improved with this scheme. The second scheme (called the horseshoe scheme, Figure 2) created a channel on the Long Beach side which did not match the orientation of the channel on the Los Angeles side. This channel was better protected from wave forces than the island scheme, where ships would have to be berthed along the exposed southerly boundary.

This paper reports on a Monte Carlo simulation of the hot electron transport phenomenon in an heterostructure semiconductor device. Two different electron populations have been simulated: the hot electrons injected via a tunneling mechanism into the base, and the thermal electrons arising from the high doping density of the ballistic device. Electron-electron scattering and plasmon-electron scattering have been introduced into the physical model which includes also electron degeneration and quantum reflections at the collector barrier. The simulation has been compared with the experimental results obtained from the THETA device at 4.2K.

Douglas-fir as one of the important natural fiber reinforced composites has found wide applications in construction. Understanding the static and dynamic stiffness of this wood helps the design and safety assessment. In this paper, the elastic moduli of Douglas-fir were measured using both static and dynamic testing methods including uniaxial compression, three-point bending and damped vibration. The compression tests delivered a Young's modulus of 4.55 GPa. Under three-point bending, the longitudinal-radial modulus of elasticity was 7.35 GPa and the longitudinal-tangential modulus was 1.63 GPa. The dynamic moduli measured by the damped vibration were higher than the corresponding static values. The longitudinal-radial dynamic modulus of elasticity was found to be 15.3 GPa and the longitudinal-tangential modulus was 9.78 GPa. It is concluded that Douglas-fir is weaker and less stiff in the longitudinal-tangential direction than the longitudinal-radial direction. The microstructure and anatomical features are believed to be the major reasons for such differences. The crack propagation along the radial direction needs to fracture the strong wood fibers. While the crack propagation along the transverse direction is mainly through the debonding of the hemicellulose. The structural analysis and morphology observation support the conclusion drawn from the static and dynamic tests. The wood is much stiffer under dynamic loadings in both longitudinal-radial and longitudinal-tangential directions. The high deformation rate in the vibration is the major contributing factor to the higher modulus obtained from dynamic tests. • Douglas-fir natural composite was tested statically and dynamically. • Elastic moduli were measured by compression, bending and vibration. • The dynamic moduli were higher than the corresponding static values. • Douglas-fir is stronger and stiffer in the longitudinal-radial direction.
