A Venture Capital Fund for Undergraduate Engineering Students at Rowan University
All engineering students at Rowan University are required to take the 8-semester Engineering Clinic sequence wherein multidisciplinary student teams engage in semester-long design projects. In addition to projects that are funded by local industry, faculty research grants or departmental budgets, a Venture Capital Fund has been created, which is specifically ear-marked for the development of original student inventions. Funding of up to $2500 per student team per semester is competitively awarded based on student-generated proposals to the Venture Capital Fund, which has been created through a series of grants from the National Collegiate Inventors and Innovators Alliance (NCIIA). To qualify for funding, a multidisciplinary student team must propose, plan and implement an original, semester-long product development enterprise. To date, eleven projects have been funded through the Venture Capital Fund. This paper describes the results of several student entrepreneurial projects and compares the results of student surveys to assess the effectiveness of entrepreneurial projects in satisfying the technical objectives of the Engineering Clinic. The results suggest that students engaged in entrepreneurial projects devote more hours per week on their projects, have more âownershipâ in their projects, and have a better understanding of the technical aspects and societal impact of their projects than their counterparts who are engaged in the more traditional engineering design projects
Theoretical Basis for Estimated Test Times and Conditions for Drop Tower and Space-Based Droplet Burning Experiments With Methanol and N-Heptane
In order to develop an extensive envelope of test conditions for NASA's space-based Droplet Combustion Experiment (DCE) as well those droplet experiments which can be performed using a drop tower, the transient vaporization and combustion of methanol and n-heptane droplets were simulated using a recently developed fully time-dependent, spherically symmetric droplet combustion model. The transient vaporization of methanol and n-heptane was modeled to characterize the instantaneous gas phase composition surrounding the droplet prior to the introduction of an ignition source. The results for methanol/air showed that the entire gas phase surrounding a 2 mm methanol droplet deployed in zero-g .quickly falls outside the lean flammability limit. The gas phase surrounding an identically-sized n-heptane droplet, on the other hand, remains flammable. The combustion of methanol was then modeled considering a detailed gas phase chemical kinetic mechanism (168 steps, 26 species) and the effect of the dissolution of flame-generated water into the liquid droplet. These results were used to determine the critical ignition diameter required to achieve quasi-steady droplet combustion in a given oxidizing environment. For droplet diameters greater than the critical ignition diameter, the model predicted a finite diameter at which the flame would extinguish. These extinction diameters were found to vary significantly with initial droplet diameter. This phenomenon appears to be unique to the transient heat transfer, mass transfer and chemical kinetics of the system and thus has not been reported elsewhere to date. The extinction diameter was also shown to vary significantly with the liquid phase Lewis number since the amount of water present in the droplet at extinction is largely governed by the rate at which water is transported into the droplet via mass diffusion. Finally, the numerical results for n-heptane combustion were obtained using both 2 step and 96 step semi-emperical chemical kinetic mechanisms. Neither mechanism exhibited the variation of extinction diameter with initial diameter
Creating an Entrepreneurial Culture at a Startup Engineering Program
In 1992, the College of Engineering at Rowan University was created as the direct result of a 2500 per semester to develop their own original inventions, âą Created the Competitive Assessment Laboratory for competitive benchmarking of consumer products. âą Developed a micro-business model in which some Engineering Clinic project teams provide engineering services (design, fabrication, modeling, etc.) to other projects, âą Hired (College of Business) an endowed chair in entrepreneurial studies, âą Created the Technological Entrepreneurship Concentration, which is a certificate program that will be populated jointly by Engineering and Business students, âą Obtained state funding to build the South Jersey Technology Park and Technology Business Incubator adjacent to the Rowan campus. This paper will describe the impact of each of these initiatives toward creating an entrepreneurial culture in our undergraduate students. It should be noted that many of these initiatives do not require a new program or major curriculum reform. Rather, our results suggest that it is possible to start with some small initiatives and build upon each initiative as the momentum for entrepreneurship develops
Integrating Design Throughout The Mechanical Engineering Curriculum: A Focus On The Engineering Clinics
At Rowan University, we have infused design into the curriculum through an eight-semester course sequence called the Engineering Clinic. Through this experience students learn the art and science of design in a multidisciplinary team environment. While many engineering programs currently include a Capstone Design course taken near the end of the college career to meet the design needs, Engineering Clinic at Rowan allows students to hone their design skills throughout their four-year career. This paper will describe in further detail the objectives and execution of each year in the design sequence, types of projects and how the Clinics complement traditional core courses in the curriculum. Impacts and benefits of the Clinics on students and faculty are discussed, as well as comparative data of Rowan Mechanical Engineering students and their peers nationally
The CatWISE2020 Catalog
The CatWISE2020 Catalog consists of 1,890,715,640 sources over the entire sky
selected from WISE and NEOWISE survey data at 3.4 and 4.6 m (W1 and W2)
collected from 2010 Jan. 7 to 2018 Dec. 13. This dataset adds two years to that
used for the CatWISE Preliminary Catalog (Eisenhardt et al., 2020), bringing
the total to six times as many exposures spanning over sixteen times as large a
time baseline as the AllWISE catalog. The other major change from the CatWISE
Preliminary Catalog is that the detection list for the CatWISE2020 Catalog was
generated using (Schlafly et al. 2019), while the CatWISE
Preliminary Catalog used the detection software used for AllWISE. These two
factors result in roughly twice as many sources in the CatWISE2020 Catalog. The
scatter with respect to photometry at faint magnitudes in the
COSMOS field, which is out of the Galactic plane and at low ecliptic latitude
(corresponding to lower WISE coverage depth) is similar to that for the CatWISE
Preliminary Catalog. The 90% completeness depth for the CatWISE2020 Catalog is
at W1=17.7 mag and W2=17.5 mag, 1.7 mag deeper than in the CatWISE Preliminary
Catalog. From comparison to , CatWISE2020 motions are accurate at
the 20 mas yr level for W115 mag sources, and at the mas
yr level for W117 mag sources. This level of precision represents
a 12 improvement over AllWISE. The CatWISE catalogs are available in
the WISE/NEOWISE Enhanced and Contributed Products area of the NASA/IPAC
Infrared Science Archive.Comment: 27 pages, 24 figure, 2 tables. Accepted for publication in ApJS.

The CatWISE Preliminary Catalog: Motions from and Data
CatWISE is a program to catalog sources selected from combined
and all-sky survey data at 3.4 and 4.6 m (W1 and W2). The
CatWISE Preliminary Catalog consists of 900,849,014 sources measured in data
collected from 2010 to 2016. This dataset represents four times as many
exposures and spans over ten times as large a time baseline as that used for
the AllWISE Catalog. CatWISE adapts AllWISE software to measure the sources in
coadded images created from six-month subsets of these data, each representing
one coverage of the inertial sky, or epoch. The catalog includes the measured
motion of sources in 8 epochs over the 6.5 year span of the data. From
comparison to , the SNR=5 limits in magnitudes in the Vega
system are W1=17.67 and W2=16.47, compared to W1=16.96 and W2=16.02 for
AllWISE. From comparison to , CatWISE positions have typical
accuracies of 50 mas for stars at W1=10 mag and 275 mas for stars at W1=15.5
mag. Proper motions have typical accuracies of 10 mas yr and 30 mas
yr for stars with these brightnesses, an order of magnitude better than
from AllWISE. The catalog is available in the WISE/NEOWISE Enhanced and
Contributed Products area of the NASA/IPAC Infrared Science Archive.Comment: 53 pages, 20 figures, 5 tables. Accepted by ApJ
Measurement of the cross-section and charge asymmetry of bosons produced in proton-proton collisions at TeV with the ATLAS detector
This paper presents measurements of the and cross-sections and the associated charge asymmetry as a
function of the absolute pseudorapidity of the decay muon. The data were
collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with
the ATLAS experiment at the LHC and correspond to a total integrated luminosity
of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements
varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the
1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured
with an uncertainty between 0.002 and 0.003. The results are compared with
predictions based on next-to-next-to-leading-order calculations with various
parton distribution functions and have the sensitivity to discriminate between
them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables,

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in âs=13âTeV pp collisions with the ATLAS detector
A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of âs=13ââTeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139ââfbâ1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015â2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV
Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at â s = 8 TeV with the ATLAS detector
Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fbâ1 of â s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente
