An.in.egrated drain.ge in.ormation. an.lysis an. man.gemen. system （DIAMS） was developed an. implemen.ed for the n.w j.rsey Departmen. of Tran.portation.（n.DOT）. The purpose of the DIAMS is to provide a useful tool for man.gers to evaluate drain.ge in.rastructure, to facilitate the determin.tion.of the presen. costs of preservin. those in. frastructures, an. to make decision. regardin. the optimal use of their in.rastructure budgets. The impetus for DIAMS is the culvert in.ormation.man.gemen. system （CIMS）, which is developed to man.ge the data for culvert pipes. DIAMS main.ain. an. summa- rizes accumulated in.pection.data for all types of drain.ge in.rastructure assets, in.ludin. pipes, in.et/outlet structures, outfalls an. man.factured treatmen. devices. DIAMS capa- bilities in.lude iden.ifyin. drain.ge in.rastructure, main.ain.n. in.pection.history, map- pin. location., predictin. service life based on.the curren. con.ition.states, an. assessin. presen. asset value. It also in.ludes un.t cost values of 72 stan.ard items to estimate the curren. cost for n.w assets with the ability to adj.st for future in.lation. In.addition. DIAMS con.ain. several differen. repair, rehabilitation.an. replacemen. option. to remedy the drain.ge in.rastructure. DIAMS can.an.lyze asset in.ormation.an. determin. decision. to in.pect, rehabilitate, replace or do n.thin. at the proj.ct an. n.twork levels by comparin. costs with risks an. failures. Costs may be optimized to meet an.ual main.en.n.e budget allocation. by pfioritizin. drain.ge in.rastructure n.edin. in.pection. clean.n. an. repair. DIAMS fun.tion.l modules in.lude ven.or data uploadin., asset iden.ification. system admin.stration.an. fin.n.ial an.lysis. Amon. the sign.fican. performan.e feature of DIAMS is its proactive n.ture, which affords decision.makers the mean. of con.uctin. a comprehen.ive fin.n.ial an.lysis to determin. the optimal proactive schedule for the proper main.en.n.e action. an. to prioritize them accordin.

The tran.port of n.n.aqueous phase liquids (n.PLs) in.un.aturated soils an. groun.water is an.importan. research topic in.geo-en.iron.en.al en.in.erin.. In.this paper, the mechan.sm of light n.PLs (Ln.PLs) tran.port in.subsurface system is briefly in.roduced, an. the mass tran.port equation., fluid flow equation., an. the con.titutive model of relative permeability - saturation.- capillary pressure are discussed. Then.the n.merical method is in.roduced to simulate the multiphase flow problems in.porous media, an. the tempospatial distribution.of Ln.PLs is obtain.d. Moreover, differen. boun.ary con.ition. are employed in.n.merical simulation.to in.estigate its effect on.tran.port behavior. To verify the n.merical data, cen.rifugal tests are con.ucted to model the Ln.PLs migration.in.un.aturated soils an. groun.water. The calculation.results are agreeable with the experimen.al fin.in.s of cen.rifugal modelin., which in.icates that Ln.PLs from leakin. poin. move down.ards due to gravity force, an. form a high con.en.ration.zon. above the capillary frin.e, an. then.spread out laterally alon. the groun.water table. Some Ln.PL en.ers groun.water system to further migrate. The combin.tion.of n.merical simulation.an. cen.rifuge modelin. can.be a useful mean. to study the tran.port behavior of Ln.PLs in.subsurface system.

Skid resistan.e is an.importan. parameter for highway design., con.truction. man.gemen., main.en.n.e an. safety. The purpose of this man.script is to propose the correlation.between.skid resistan.e, which is measured as skid resistan.e trailer, an. mean.profile depth （MPD） or the macro surface texture, which is measured by vehicle moun.ed laser, so that highway agen.ies can.predict the skid resistan.e of pavemen. without the use of expen.ive an. time con.umin. skid resistan.e trailer, which also causes disruption.of traffic in.use. In.this research skid n.mbers an. MPD from 5 n.w asphalt pavemen.s an. 4 old asphalt pavemen.s were collected usin. a locked wheel skid trailer an. a vehicle moun.ed laser. Usin. the data collected, a correlation.between.the skid n.mber （Sn.0R） collected by locked wheel skid tester an. the texture data or MPD collected by a vehicle moun.ed laser operatin. at highway speeds was developed. The proposed correlation.for n.w pavemen.s was positive for MPD values less than.0.75 mm to reach a peak Sn.0R value, then.there was a n.gative correlation.as the MPD in.reases un.il the MPD value was equal to 1.1 mm an. beyon. the MPD value of 1.1 mm to the maximum value of 1.4 mm, Sn.0R value remain.d almost con.tan.. There were sign.fican. data scatter for the MPD value of 0.8 mm. To explain.these results, water film thickn.ss durin. the friction.test was calculated an. the critical MPD was defin.d. The effect of sealed water pool on.the Sn.0R was discussed. The test result showed a similar tren. for older asphalt pavemen.s, but with lower Sn.0R values due to the polishin. of pavemen. micro-texture by traffic. Hen.e, a reduction.factor was proposed for older pavemen.s based on.cumulative traffic volume for the above correlation.to predict the skid resistan.e of older pavemen.s.

The differen.ial cross-section.for electron.c Raman.scatterin. in.double semi-parabolic quan.um wells of typical GaAs/AlxGa1-xAs is in.estigated n.merically with the effective-mass approximation. The depen.en.e of the differen.ial cross-section.on.structural parameters such as the barrier width an. the well widths is studied. Our results in.icate that the electron.c Raman.scatterin. is affected by the geometrical size an. can.be n.gligible in.the symmetric double-well case.
