Optimizing ?0 information from the Jason-2 altimeter
A radar altimeter's normalized backscatter, ?0, is used in many oceanographic applications, to infer values of wind speed, wind stress, rain rate and the presence of biogenic slicks. The waveform retracker used to estimate the key geophysical variables for the altimeters on the Jason-1 and Jason-2 satellites shows increased small-scale variability since the problem is ill-conditioned. A simple empirical adjustment to ?0 improves the separability between various parameters and also improves the along-track profiles of ?0. This leads to i) more realistic wind fields, ii) better discrimination of rain events, and iii) improved comparison between the Jason-1 and Jason-2 altimeters during their tandem mission
Helley-Smith bodemtransport meter
Morfologische berekeningen in de rivierwaterbouwkunde zijn sterk afhankelijk van metingen. Modellen worden geijkt aan de hand van het gemeten sedimenttransport en een zo groot mogelijke nauwkeurigheid wordt hiervan verlangd. Het meten van het zgn. bodemtransport staat in deze studie centraal; in het bijzonder het gebruik van de bodemtransportmeter 'Helley-Smith'. Dit instrument, ontwikkeld in de zeventiger jaren, wordt in de Verenigde Staten veelvuldig gebruikt. Echter, officieel is het apparaat nog niet geijkt en "gesanctioneerd". In 1983 heeft het Waterloopkundig Laboratorium dit instrument voor de eerste maal gebruikt bij metingen in Tana River, Kenya. De onbekendheid van het instrument en het ontbreken van een officieel testrapport vormden de aanleiding tot nader onderzoek omtrent de Helley-Smith. Een literatuurstudie is verricht naar het gebruik en de (onofficieie) ijkingen van het apparaat. Hieruit volgde een overzicht van de beschikbare modellen en aanbevelingen voor het gebruik. Over de meest belangrijke eigenschap van het instrument, nl. de vangst coefficient die het verband legt tussen gemeten en werkelijk transport, was en is nog weinig bekend. De gegevens hierover werden in deze studie verzameld en beoordeeld. Na een veld-ijking van het instrument in East Fork River bleek de vangst coefficient ongeveer 100 % te bedragen. Deze waarde is slechts toepasbaar voor gebruik in gelijksoortige omstandigheden als in de veld-ijking. Een grootte van 100 % lijkt vooralsnog goed hanteerbaar te zijn bij lage transporten (gemiddelde kleiner dan 0,40 kgjm*s), in de korrelklasse van 0,50-8,0 mm en bij afwezigheid van zwevend transport in eerdergenoemde korrelklasse. Passen we deze voorwaarden toe op het gebruik van de Helley-Smith in Tana River dan blijkt al dat aan de voorwaarden niet voldaan kon worden. Analyse van de meetresultaten en de hydraulische omstandigheden liet zien dat de aanname van 100 % als vangst coefficient verworpen moet worden. De invloed van het zwevend transport leek groot; tevens werden de metingen waarschijnlijk ook nog verstoord door het verstopt raken van de vangkorven met zeer fijn sediment of organisch materiaal. Nader onderzoek lijkt gewenst naar de vangst coefficient van de Helley-Smith voor kleine korrelklassen (diameter kleiner dan 1,00 mm) en de invloed van fijn sediment en organisch materiaal op de hydraulische coefficient.vloeistofmechanicaHydraulic EngineeringCivil Engineering and Geoscience

Anecdotes (Source: Morton M. Smith Retirement File, 1990)
• [Author not named]: “I really believe Mort’s favorite air-machine was the
DeHavilland ‘Speedster’ or Beaver. Seriously, when it came to multiple use or being
capable of handling many tasks, it was by far the best bush craft I ever flew. It had
one unredeeming feature however – it was slower than the second coming of the ‘Big
Man’ – in fact, it was the only aircraft I knew of that a tailwind wouldn’t help. I had
several affectionate adjectives for the machine and I used to relate to Mort about the
‘Speedster’s’ inability to develop much forward motion. I believe he took this
bitching with a grain of salt – until he drove it himself for awhile. Finally, after a
long summer, he called and said I was probably right; ‘it probably wouldn’t go much
over 100 miles per hour coming straight down.’”
• Vern Stotts: Some of his greatest thoughts and lessons for me were:
a. “I could hit these seaducks more often if they tasted better,” meant that with
practice one can rationalize anything.
b. When he said, “We can get this 206 off the water in less than 1 minute when
everyone is down to their high school weight,” it translated into don’t stuff rocks
in your personal kit to take home as souvenirs.
c. After a clapper rail hunting trip to the Eastern Short of Virginia, he remarked,
“We should shoot these critters only with a singleshot, 4-10 pistol fired with the
left hand after a cross-draw”, meaning that modern equipment can take away the
thrill of a full bag.
d. And, finally, after a perfect 2-point landing, he stressed that, “We can be happy
that we didn’t do it the other way around and land with our wheels down on the
water”, teaching me the hows, whys, whens, and beauty of a personal checklist.
• Bob Blohm: Of course, Mort, your red station wagon was legendary at the [Patuxent
Wildlife Research] center and how many Monday lunchtime discussions focused on
your weekend activities with your son to prepare the vehicle for the next week’s
drive. And, your love of doughnuts (particularly stale ones, at least 3-4 weeks old)
and old hunting clothes (the more holes and dangling threads, the better) is known far
and wide.
• Art Hawkins: After you joined the FWS Airforce it was fun getting together with
you, Don Smith, Maury Lundy and others to compare notes. You were unique among
most of the pilots listed above in that you were completely interchangeable between
ground and air duty. In fact, on days when you couldn’t fly, for one reason or
another, you joined the guys in the trenches, of your own free will. … One thing for
sure, I never worked with anyone I’ve enjoyed working with more, whether in the
Louisiana marshes or on the Canadian Prairies, whether at wing bees or Tech
meetings. Your cheerful attitude and dedication to duty made the job easier.
• John Tautin: I still recall my first months with FWS in 1974 and being assigned to a
duck banding station in Alberta. My first flight in FWS aircraft was when you flew
me from Saskatoon to Brooks to meet up with the banding crew. We (you) had to
make a tough landing in a crosswind on sod. It went well, and I still recall being
impressed and thinking that this pilot has the right stuff. I went on to learn that the
other pilots, our flyway biologists, were also fine biologists and good, safe pilots.
You deserve a lot of credit for that, having been in charge of that operation. Being in
charge as Branch Chief, Surveys and Operations, is how I most often think of you.
You have been one of the best managers I have seen, fair and honest with people,
managing to get the job done well with limited resources, and firm and decisive when
need be on issues and problems. I learned a lot from you that helps me now that I am
in charge of [the Bird Banding Laboratory]

On the homotopy type of multipath complexes
A multipath in a directed graph is a disjoint union of paths. The multipath complex of a directed graph G is the simplicial complex whose faces are the multipaths of G. We compute Euler characteristics, and associated generating functions, of the multipath complexes of directed graphs from certain families, including transitive tournaments and complete bipartite graphs. We show that if G is a linear graph, polygon, small grid or transitive tournament, then the homotopy type of the multipath complex of G is always contractible or a wedge of spheres. We introduce a new technique for decomposing directed graphs into dynamical regions, which allows us to simplify the homotopy computations

OEF/OIF veterans with and without PTSD : levels of relationship distress, social support, combat experience, and deployment
As Veterans have returned home from the OEF/OIF wars they have faced many struggles with reintegration. Studies of Veterans returning home have found rates of PTSD as high as 18 % (Hoge et al., 2004; Hoge, Terhakopian, Castro, Messer, and Engel, 2007). The symptomatology of PTSD has historically complicated Veterans primary relationships as well other interpersonal relationships and this study seeks to look at the relationship between PTSD and interpersonal distress in a sample of Veterans returning from the OEF/OIF wars. The author conducted secondary analysis of data from a survey taken by a sample of Connecticut Veterans (n = 620) following the OEF/OIF wars. Veterans who screened positive for PTSD (n=58) were compared to Veterans who did not screen positive for PTSD (n =472). The author analyzed levels of relationship distress, combat experience, post-deployment social support, and deployment location. Veterans with PTSD reported higher levels of relationship distress, combat experience, and less social support than Veterans without PTSD (p\u3c .001). Higher PTSD symptomatology was significant (p\u3c .001) with deployment to Iraq compared to all other deployment locations in the survey. Study findings indicate a need for creating greater practical and emotional support for Veterans returning with PTSD through clinical collaboration with the Veteran, caregivers, family members, close friends, and the larger community
