Technology transfer from U.S. government and University R&D Laboratories
Technovation, 1991Co-Authors: Barry Bozeman, Michael CrowAbstract:Despite the increased interest in domestic technology transfer, there is surprisingly little empirical evidence on determinants of technology transfer activity. This study presents results from a national survey of more than 900 Laboratories, focusing on a sub-sample of 134 government Laboratories and 139 University Laboratories. An environmental dependence model of technology transfer activity is presented, arguing that influence of political authority is a major determinant of technology transfer activity. Tests of the model indicated that scientific and technical mission diversity is particularly important in understanding technology transfer to both government and industry. However, a variety of measures of political boundary spanning are quite important in transfer to government but not so to industry. Likewise, the nature of the resource base (government vs. industrial) is strongly related to the choice to transfer technology to, respectively, government and industry. © 1991.

Technology transfer in U.S. government and University Laboratories: Advantages and disadvantages for participating Laboratories
IEEE Transactions on Engineering Management, 1992Co-Authors: David Coursey, Barry BozemanAbstract:Based on findings from a national survey of government and University R&D lab directors, the authors examine perceptions of advantages and disadvantages of technology transfer. Four points stand out. First, laboratory directors, regardless of sector, are generally optimistic about the payoffs of technology transfer. Second, there is surprisingly little difference between University and government laboratory directors' views. Third, the research mission of the laboratory is related to directors' assessments of the problems and benefits accruing from technology transfer activity. Finally, Laboratories stressing development research encounter fewer disadvantages from technology transfer activity than those involved chiefly in basic or applied research oriented Laboratories. The benefit most commonly cited by both government and University laboratory directors is increased public visibility for the Laboratories' activities, and both indicate that the greatest problem is time taken away from the Laboratories research activities

air conditioned University Laboratories comparing co2 measurement for centralized and split unit systems
Journal of King Saud University: Engineering Sciences, 2017Co-Authors: Mohamad Fahmi Hussin, Mohd Rodzi Ismail, M S AhmadAbstract:Abstract Universities are designed for higher education learning, and improving University indoor air quality (IAQ) is essential to the enhanced performances of students and staff members alike. The majority of IAQ problems are due to inadequate ventilation in University buildings. Carbon Dioxide (CO2) measurements have become a commonly used screening test of IAQ because measurement levels can be used to evaluate the amount of ventilation and general comfort. This paper examines CO2 field measurement for undergraduate practical classes. Ten air conditioned Laboratories with ventilation were chosen for CO2 field measurement. CO2 was monitored under indoor and outdoor conditions. Indoor CO2 concentration for Laboratories 1 and 10 is observed to be higher than 1000 ppm which indicated inadequate ventilation, while other Laboratories showed CO2 concentrations less than 1000 ppm. Air capacity and outdoor air were calculated based on the design documentation. A comparison between design and actual outdoor air/person values indicates that the air conditioning systems of the Laboratories had adequate ventilation.

thermal comfort study of air conditioned University Laboratories
International Journal of Environmental Technology and Management, 2014Co-Authors: Mohamad Fahmi Hussin, Mohd Rodzi Ismail, M S AhmadAbstract:In tertiary education institutions, good indoor air quality (IAQ) provides a conducive environment for teaching and learning activities. A field study on the environmental conditions and occupants' comfort was carried out in six Laboratories at Universiti Sains Malaysia. The study evaluates the current thermal comfort conditions using objective measurement and subjective assessment. The measured environment parameters were air dry-bulb temperature, relative humidity and air velocity. The subjective assessment concerned the judgement of the respondents about the thermal environment at the moment of measurement. The results obtained showed that the mean air dry-bulb temperatures recorded in the six Laboratories are ranged between 22.7°C and 24.4°C. The range is within the recommended range based on the Code of Practice on Indoor Air Quality (2010). The measured air velocity and relative humidity (RH) were within the limits of thermal comfort standards. Based on the occupants' perception of thermal sensation, RH and air movement, generally more than 70% of the respondents were satisfied with the existing conditions in the Laboratories. The overall comfort vote and predicted mean vote (PMV) index found the occupants to be in the range of '0' (neutral) and '+1' (comfortable).

subjective perception of thermal comfort study in air conditioned University Laboratories
Procedia - Social and Behavioral Sciences, 2013Co-Authors: Mohamad Fahmi Hussin, Mohd Rodzi Ismail, M S AhmadAbstract:Abstract Thermal comfort is the condition of mind that expresses satisfaction with complex thermal factors. There are three main factors that can affect the human comfort, which must be considered by engineers before designing air-conditioning systems; effective temperature, relative humidity and air motion. Present study aims to investigate on the environmental conditions and occupants comfort in teaching and learning Laboratories in Engineering Campus and Main Campus of Universiti Sains Malaysia. A study was carried out in order to identify differences in the perception of thermal comfort of laboratory staffs in centralized air-conditioned and ‘split-unit type of air-conditioned Laboratories used in Engineering Campus and Main Campus, respectively. American Society of Heating, Refrigerating and Air-conditioning Engineer (ASHRAE) [1] 7-points scale of thermal sensation was used to evaluate thermal sensation of the laboratory occupants. Based on the occupants’ perception towards the scale, generally 75% and 55% of the respondents in Main Campus and Engineering Campus respectively voted within the central three categories of thermal acceptibility (-1, 0, 1). Besides that, based on 5-Likert scale on general comfort, 85% and 87% of the respondents from Main Campus and Engineering Campus respectively found to be satisfied with their laboratory environment.

Seismic risk assessment of residential buildings in Italy
Bulletin of Earthquake Engineering, 2020Co-Authors: Mauro Dolce, Andrea Prota, Barbara Borzi, Francesca Da Porto, Sergio Lagomarsino, Guido Magenes, Claudio Moroni, Andrea Penna, Maria Polese, Elena SperanzaAbstract:The last National Risk Assessment NRA for Italy was developed at the end of 2018 by the Department of Civil Protection (DPC) in response to the specific requirement of the Sendai Framework for Disaster Risk Reduction 2015–2030 to periodically adjourn the assessment of disaster risk. The methodology adopted to perform seismic risk assessment and build national seismic risk maps was specifically developed to comply with the recent Code for Civil Protection, issuing that, in addition to a solid scientific base, risk assessment should be characterized by a wide consensus of the scientific community. As a result, six research units belonging to two Centers of Competence of the DPC, namely ReLUIS (Network of University Laboratories for seismic engineering) and EUCENTRE (European Centre for Training and Research in Earthquake Engineering), collaborated under the guidance and coordination of DPC to produce the recent updating of national seismic risk maps for the residential building stock. This paper describes the methodology adopted to develop the consensus-based national seismic risk assessment and presents the main results in terms of expected damage and impact measures (unusable buildings, homeless, casualties, direct economic losses).
