This paper discusses the development of an afternoon peak period trip generation model for both work and non-work trips. Three data sources are used in model development, a Household Travel Survey, a Census-Update Survey, and a Trip Generation Study. Seven one-direction trip purposes are defined, specifically accounting for stops made on the return trip from work to home. Trips are classified b...

Convenience markets with gasoline pumps have flourished throughout the United States in the past 10 years. The growing demand for self-service gasoline and convenience grocery goods, readily accessible with fast service, have fueled a boom in the convenience market business. As transportation engineers and planners, we are asked to determine the impacts of developments on the transportation sys...

A trip-let is an object as shown on the cover of Hofstadter’s book Gödel, Escher, Bach: a solid, threedimensional object that, when viewed from three orthogonal directions, shows three different letters. In this paper we consider two problems related to the construction of such objects for a given set of three letters. First, we want to know whether the silhouettes of the object correspond to t...

One of the main challenges in developing magnetic resonance imaging (MRI) systems is to create a static coil that needs to generate magnetic field density along with the characteristics of optimal homogeneity and magnitude size. To do this, two N42 Block PMs are used and the iron core is designed and optimized in accordance with the dimensions of PM pieces using ANSYS Maxwell software. Then, al...

The principle object of this paper is to offer a modified design of Rogowski coil based on its frequency response. The improvement of the integrator circuit for nullifying the phase difference between the waveforms of the measured-current and the corresponding terminal voltage is a further object of this investigation. This paper addresses an accurate, yet more efficient measuring and protect...

As more and more travelers wish to create their personalised trip itineraries, the provision of geographical information and services on travel websites is an unavoidable necessity. The evolution of geoportals, geocollaborative portals and web 2.0 present numerous opportunities and services for making the trip planning process less complex and time consuming, more efficient and more social and ...

statement of problem: a recent technique (mbt) has been introduced for easy and efficient orthodontic treatment by means of straight wire fixed appliances. although this technique has many advantages, in space closure stage causes up righting problem in upper incisors, which should be adjusted by applying additional torque in anterior region. purpose: the purpose of this clinical trial was to d...

hot spots are among the most serious operational issues in furnaces as they may result in the destruction of tubes. hence, it is essential to locate such hot spots precisely on the tube surfaces inside the industrial furnaces in order to secure a safe design and operation. in the current study, we have extended the model proposed by talmor in order to precisely locate the combustion hot spots o...
