    NONLINEAR MODELING AND PREDICTION OF A RIVER FLOW SYSTEM (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 34 (1998), S. 0

    Notes: : Model estimation and prediction of a river flow system are investigated using nonlinear system identification techniques. We demonstrate how the dynamics of the system, rainfall, and river flow can be modeled using NARMAX (Nonlinear Autoregressive Moving Average with eXogenuous input) models. The parameters of the model are estimated using an orthogonal least squares algorithm with intelligent structure detection. The identification of the nonlinear model is described to represent the relationship between local rainfall and river flow at Enoree station (inputs) and river flow at Whitmire (output) for a river flow system in South Carolina.

    Heat transfer to pulsating turbulent flow in an abrupt pipe expansion (2003)
    Bradford : Emerald
    International journal of numerical methods for heat & fluid flow 13 (2003), S. 286-308 
    Details
    ISSN: 0961-5539

    Notes: A numerical investigation aimed at understanding the flow and heat transfer characteristics of pulsating turbulent flow in an abrupt pipe expansion was carried out. The flow patterns are classified by four parameters; the Reynolds number, the Prandtl number, the abrupt expansion ratio and the pulsation frequency. The influence of these parameters on the flow was studied in the range 104〈Re〈5×104, 0.7〈Pr〈7.0, 0.2〈d/D〈0.6 and 5〈f〈35. It was found that the influence of pulsation on the mean time-averaged Nusselt number is insignificant (around 10 per cent increase) for fluids having a Prandtl number less than unity. This effect is appreciable (around 30 per cent increase) for fluids having Prandtl number greater than unity. For all pulsation frequencies, the variation in the mean time-averaged Nusselt number, maximum Nusselt number and its location with Reynolds number and diameter ratio exhibit similar characteristics to steady flows.

    Notes: A disaster and a crisis are two different, and related events. The two terms are sometimes used interchangeably. Man-made disaster that occurs at an industrial organization, may develop into an industrial crisis. Crisis can happen to any organization. It has been noted that there were no universally accepted definitions yet developed for disaster and crisis. There is also no universally available criteria, to define the disaster in terms of the consequences, such as the casualties and the cost of damage. This paper reviews the definitions, types, characteristics, criteria and models of disaster and crisis. Also the types of crisis were rearranged and the differences between the disasters and crises have been summarized.

    Notes: Major hazard installations (MHIs) are dealing with hazardous substances which exceed the threshold quantity. MHIs are characterized by tight coupling and high complexity. Due to their complexity, MHIs require well trained managers who have good experience at all levels to manage the operations successfully. The managements of major hazard installations play a vital role in the success or failure of their installation. The world has witnessed many incidents in major hazard installations due to failure of the management at all levels. This paper summarizes in brief the management errors for several incidents which occurred worldwide. Also, the paper reviews the management errors which led to an incident at a petrochemical plant in East Malaysia.

    Environmental concerns, knowledge and practices gap among Malaysian teachers (2003)
    Bingley : Emerald
    International journal of sustainability in higher education 4 (2003), S. 305-313

    Notes: Environmental problems are caused directly or indirectly by the patterns of production by industries, patterns of consumption and behavior of the consumers. The shaping of attitude and values, commitment and skills needed to preserve and protect the environment begins at an early age. Hence educators play an influential role in developing new patterns of behaviors for individuals. Accordingly, aims to determine the level of knowledge, environmental concern and ecologically conscious consumer behavior and identify the extent of involvement in nature-related activities of school teachers. Also investigates the relationships between these variables. The subjects were 285 school teachers who were randomly selected from ten regular government schools in the state of Selangor, Malaysia. A survey was conducted using drop and collect method. The data illustrated the presence of high level of environmental concern among the teachers. The environmental knowledge was fair but generally poor in understanding of the underlying causes of environmental problems. The practices of environmentally responsible behavior were not in concert with the level of concern and knowledge. The respondents were not actively involved in nature-related activities. Proposes ways of enhancing the ecological awareness and responsibilities of the teachers.

    Correlation between CMV genotypes, multiple infections with herpesviruses (HHV-6, 7) and development of CMV disease in kidney recipients in Kuwait (2003)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The possible correlation between cytomegalovirus, human herpesvirus types 6, 7 and cytomegalovirus-related clinical symptoms was studied in kidney transplant patients in Kuwait. Cytomegalovirus infection was diagnosed using the pp65 antigenemia assay. DNA of cytomegalovirus was detected by nested polymerase chain reaction (nested-PCR). PCR was also used to amplify the genes coding for structural proteins of human herpesvirus-6 (240 bp) and human herpesvirus-7 (186 bp). Glycoprotein B genotypes of cytomegalovirus were determined by restriction fragment length polymorphism. The average number of cells positive for cytomegalovirus pp65 antigen showed a steady increase with the severity of the cytomegalovirus-related symptoms. Furthermore, cytomegalovirus pp65 antigen positivity was significantly more frequent among recipients of cadaver kidney (45.5%) than among those who received live related kidneys (22.6%). Cytomegalovirus gB genotype 1 was detected more frequently (P〈0.036) in recipients with live related donor kidney (38%) than in patients of cadaver kidney (13%). The genome of human herpesvirus-6 was detected at the same rate in patients with or without cytomegalovirus-related symptoms. However, the genome of human herpesvirus-7 was detected significantly more frequently (P〈0.0001) in asymptomatic patients (41.7%) than in recipients with symptomatic cytomegalovirus infection (17%). We conclude that cytomegalovirus gB genotypes are not associated with the outcome of a cytomegalovirus infection in kidney transplant patients, that human herpesvirus-6 does not play a role in cytomegalovirus pathogenesis and that the role of human herpesvirus-7 in cytomegalovirus-related morbidity in kidney recipients remains unclear.

    Three-Photon Absorption in InAs (1998)
    Springer
    Optical and quantum electronics 30 (1998), S. 193-200 
    Details
    ISSN: 1572-817X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract Using 125 ps laser pulses, we observe three-photon absorption in room temperature InAs at a wavelength of 9.54 µm. This effect is readily identified by temperature-tuning the semiconductor bandgap through the three-photon absorption edge. A three-photon absorption coefficient of K3 = 1 ± 0.6 × 10-3 cm3 MW-2 is extracted from non-linear absorption data obtained with an open-aperture Z-scan. Time-resolved measurement at high irradiance reveals an increase of absorption due to hot carriers. We also present an autocorrelation measurement of our CO2 laser pulse that shows two complete optical free-induction-decay cycles.

    Temporal Constraint Satisfaction Techniques in Job Shop Scheduling Problem Solving (1998)
    Springer
    Constraints 3 (1998), S. 203-211 
    Details
    ISSN: 1572-9354
    Keywords: temporal constraint satisfaction ; job shop scheduling
    Source: Springer Online Journal Archives 1860-2000
    Topics: Computer Science
    Notes: Abstract We describe a restriction of Dechter, Meiri and Pearl's TCSPs (Temporal Constraint Satisfaction Problems) sufficiently expressive to represent any job shop scheduling problem. A solver based on the restriction is then described, which is similar to Ladkin and Reinefeld's qualitative interval network solver; except, however, that the filtering method used during the search is not path consistency but either ULT (Upper-Lower Tightening) or LPC (Loose Path- Consistency), which are both less effective but have the advantage of getting rid of the so-called “fragmentation problem”.
