Performance Assessments of Technology Transfer Offices of Thirty Major US Research Universities in 2012/2013

The activities and performance of thirty major universities technology transfer offices (TTOs) selected from major US universities are quantitatively assessed and compared. Six leading metrics, including TTOs’ revenue, as well as quantity of invention disclosures, patent applications, patents granted, licenses signed, and startup companies launched, are used to develop a single overall performance metric (OPM) for representing the performance of the TTOs. The OPM are then evaluated for each of the thirty universities and their OPM scores are compared to each other to establish the reliability and effectiveness of a comprehensive OPM. A patenting control ratio (PCR) is also calculated to guide a TTO in setting its patenting strategy and procedures. These two metrics should be able to provide a comprehensive overview of how good is the TTO of a university as compare to those of its peers and, even more importantly, how the program fares globally

Performance Evaluations of Technology Transfer Offices of Major US Research Universities in 2012/2013

By analyzing the highlights of the major activities reported by the technology transfer offices (TTOs) of twenty US major universities, the performances of TTO activities are quantitatively assessed and the associated scores are compared with each other. The key performance indicators, which govern the success of the university technology transfer, are specifically selected and examined. Two normalized metrics, overall performance metric (OPM) and patenting control ratio (PCR), which are the representing combined indicators for the TTO performance, are developed and demonstrated. The two metrics are evaluated for each university selected and compared to specifically provide a comprehensive overview of how good is the TTO of a university as compare to those of its peers. Finally, the factors for a successful TTO are described and the major unsolved issues are also discussed

Low cost membrane contactors based on hollow fibres

Membrane contactors are used to solve different chemical engineering tasks (e.g. water saturation with gases). Such elements are traditionally used for bubble less oxidation of blood. However, their industrial applications are rather limited by their high investment costs. This is probably the main reason why membrane contactors are not used so widely, e.g. classical absorbers, etc. If potted bundles of hollow fibres are available, then it is a relatively simple task to design an ad hoc membrane contactor. However, it must be emphasised that to achieve the highest mass transfer efficiency requires a rather time-consuming tuning of each ad hoc designed contactor. To check the differences by water evaporation were aligned two modes, the water inside the hollow fibre membrane and fan air outside, next with the water outsides and flowing pressure air inside the membrane

Polymer hollow fibre shell and tube heat exchanger for liquid-liquid applications

Paper provides comparison of different heat exchangers which differ in length, number and material of fibres. It also deals with an influence of various arrangement of fibres on the efficiency of heat exchangers (HEs). These have a potential to be used in low temperature and low flow rate applications. Number of Shell and tube Polymer heat exchangers were fabricated with various polymers and tested. The heat transfer performance and pressure drops were studied with hot water at 60 and 80 degrees C flowing through the shell side. It was observed that heat transfer rates (up to 36 kW), and the overall heat transfer coefficients of these devices were 647-1314 W/ (m2K) for water-water applications, and pressure drops are competitive to conventional metal Shell and Tube heat exchanger.Papers presented at the 13th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Portoroz, Slovenia on 17-19 July 2017 .International centre for heat and mass transfer.American society of thermal and fluids engineers

The effect of water temperature on cooling during high pressure water descaling

Production of hot rolled steel plates is connected with high temperatures at which steel reacts with oxygen in the atmosphere and oxide layers (scales) are formed on the surface. Scales affect the surface quality of the product and must be eliminated before the product enters any further rolling operations. The scales are usually removed by high pressure flat jet water nozzles in a process called hydraulic descaling. One side effect of this form of descaling is intense cooling of the product, which runs counter to the purpose of descaling. One way to decrease this effect is to use water at higher temperatures. Laboratory experiments were performed in order to determine the degree of influence of water temperature on the intensity of cooling. Temperature measurements were used as an input for inverse algorithm calculations and heat transfer coefficient determinations. The variables were computed as a function of time and position. The results were compared and significant decrease in the cooling intensity was observed. The findings are discussed in detail
