An approximate solution of the d.d.mensional Schrod.nger equation with the mod.fied.Posehl-Teller potential is obtained.with an approximation of the centrifugal term. Solution to the correspond.ng hyper-rad.al equation is given using the conventional Nikiforov-Uvarov method. The normalization constants for the Poschl-Teller potential are also computed. The expectation values of 〈r^-2 and.〈V（r）〉 are also obtained.using the Feynman- Hellmann theorem.

Ensuring ad.quate access to truck parking is critical to the safe and.efficient movement of freight traffic. There are strict fed.ral guid.lines for commercial truck d.iver rest period.. Rest areas and.private truck stops are the only places for the trucks to stop legally and.safely. In locations without sufficient parking areas, trucks often park on interstate ramps, which create safety risks for other interstate motorists. Historically, agencies have employed.costly and.time intensive manual counting method., camera surveillance, and.d.iver surveys to assess truck parking. Connected.truck d.ta, available in near real-time, offers an efficient alternative to practitioners to assess truck parking patterns and.id.ntify areas where there may be insufficient safe parking spaces. This paper presents a case stud. of interstate I-70 in east central Ind.ana and.d.cuments the observed.spatiotemporal impacts of a rest area closure on truck parking on nearby interstate ramps. Results showed.that there was a 28% increase in parking on ramps d.ring the rest area closure. Analysis also found.that ramps closest to the rest area were most impacted.by the closure, seeing a rise in truck parking sessions as high as 2.7 times. Parking d.ration on the ramps d.ring rest area closure also increased.d.astically. Although it was expected.that this would.result in increased.parking by trucks on ad.acent ramps, this before, d.ring, after scenario provid.d.an id.al scenario to evaluate the robustness of these techniques to assess changing parking characteristics of long-haul commercial trucks. The d.ta analytics and.visualization tools presented.in this stud. are scalable nationwid. and.will aid.stakehold.rs in informed.d.ta-d.iven d.cision making when allocating resources toward. improving the nations commercial vehicle parking infrastructure.

While we eagerly anticipate SMILE’s(Solar wind.Magnetosphere Ionosphere Link Explorer)unpreced.nted.X-ray observations of the Earth’s magnetosheath and.the initiation of a new era of magnetospheric research,it seems appropriate to look ahead.to the abilities of the next generation of astrophysics *** these,the Line Emission Mapper(LEM),a large aperture micro-calorimeter based.mission,is currently planned.to be able to observe the magnetosheath at high spectral resolution(~2 eV).With a field.of view of~30′,LEM will allow higher spatial resolution and.higher cad.nce measurement of the motion of a very small portion of the magnetopause over relatively short period. of time(multiple hours),complementing SMILE’s global ***’s strength is its spectral *** will be able to measure the abund.nce of a broad.range of elements and.ionization states,many of which are inaccessible to current in situ instruments,and.will be able to separate the emission from the magnetosheath from the emission from the cosmic X-ray background.using the d.fference in their relative velocities.
