We specify and estimate a joint model of residential density, vehicle use, and fuel consumption that accounts for both self selection effects and missing data that are related to the endogenous variables. Our model is estimated on the California subsample of the 2001 U.S. National Household Transportation Survey (NHTS). Comparing two California households that are similar in all respects except...

Social Interactions and Labor Market Outcomes in Cities We develop a model where information about jobs is essentially obtained through friends and relatives, i.e. strong and weak ties. Workers commute to a business center to work and to interact with other people. We find that housing prices increase with the level of social interactions in the city because information about jobs is transmitte...

Model Independent Analysis (MIA), which employs statistical methods to reveal one-micron charge-induced centroid changes in pulse-by-pulse beam-position-monitor (BPM) measurements at the SLAC linac [1] has been extended to storage rings, and is here applied at PEP-II to analyze transverse motion. The beam is resonantly excited by a shaker in the horizontal and vertical directions and 2050 conse...

We verify all quadrupole strengths (both normal and skew) and determine sextupole feed-downs as well as all BPM gains and BPM cross-plane couplings by an SVDenhanced least-squares fitting of the phase advances (only those which are accurately determined) and the Green’s functions (specified by the local transfer matrix components R12, R34, R32, and R14). The phase advances and the Green’s funct...

To select a more suitable turbulence model to study tire aerodynamics, the characteristics of deformed profile 185/65 R14 passenger were reproduced using 3D printing technology. Based on distance from automobile chassis ground, partially loaded with height 150 mm was selected in this paper, and surface pressure coefficient determined wind tunnel test. A computational fluid dynamics (CFD) establ...

This paper estimates hedonic price models for a sample of 610 vacation rental houses located in the vicinity of a lake and four-season ski-golf resort. Hedonic semi-logarithmic regression models are estimated for peak summer and peak winter rentals for 2008. The regression estimates for weekly rental prices are conditioned on explanatory variables for house size, house quality, and recreation f...

Spatial Mismatch, Search Effort and Urban Spatial Structure* The aim of this Paper is to provide a new mechanism for the spatial mismatchhypothesis. Spatial mismatch can here be the result of optimizing behaviouron the part of the labour market participants. In particular, the unemployed canchoose low amounts of search effort and long-term unemployment if theyreside far away fro...

<p><span>Since long term evolved release 14 (LTE R14), the device to (D2D) communications have become a promising technology for in-band or out-band mobile communication networks. In addition, D2D constitute an essential component of fifth-generation network (5G). For example, improve capability communication, reduce power dissipation, latency within networks and implement new appli...
