The real title of many history books is actually the subtitle, while colorful phrase before colon merely decorative. Examples that come to mind include Blood in Water, Our Beloved Kin, and What Hath God Wrought, titles barely hint at what lies between book covers. Not so with Richard DeLuca's Paved Roads Public Money: Connecticut Transportation Age Internal Combustion. This does deal broadly tr...

We present an active approach for discriminating different materials by impulsively contacting (hitting) them, and sensing and interpreting the resulting sounds. In theory, the angle of internal friction is diagnostic of material, but invariant over object shape. In our experiments, we observe that the angle of internal friction is not invariant over the frequency of the sound spectrum for whic...

An artificial neural network (ANN) model was employed to predict the soil cohesion and soil internal friction angle. The soil samples were collected from different cultivated sites in seven regions in Saudi Arabia. Direct shear box method was used to determine soil cohesion and soil internal friction angle. The input factors to ANN model were soil dry density, soil moisture content and soil tex...

statement of problem: the goal of a successful endodontic surgery is to establish an adequate seal in apical region. therefore during surgery, root-end resection is essential for an appropriate situation and proper access.purpose: the aim of this study was to determine the most appropriate root-end resection angle to establish adequate apical seal in periapical surgerymaterials and methods: for...

molecular modeling analysis of charge density and heat of fornation by pm3 method as well as c, h nmr and 2d-nmr measurements of histidine (substrate) and some of its derivatives as histidine decarboxylase inhibitors were performed. it was established that the atom, usually nitrogen, which forms internal aldimine with pyridoxal5 -phosphate (plp), (coenzyme), has negative and almost equal charge...

slope stability analysis is an enduring research topic in the engineering and academic sectors. accurate prediction of the factor of safety (fos) of slopes, their stability, and their performance is not an easy task. in this work, the adaptive neuro-fuzzy inference system (anfis) was utilized to build an estimation model for the prediction of fos. three anfis models were implemented including g...

children need to learn to use the roads safety. road safety is essential for children’s freedom, development and exercise. when walking near a road it is a good idea to: 1. hold your child's hand. 2. don't let them run ahead. 3. look out for and encourage your child to be aware of hidden entrances or driveways crossing the pavement. 4. put reins on a younger child if they're not ...

The goal in the management of distal humerus fractures is to obtain rigid internal fixation that allows immediate rehabilitation of the extremity. The advent of anatomic plating systems as well a systematic approach to these injuries facilitates these goals. This article outlines our approach to these complex problems from injury through rehabilitation.

We propose a range estimation method for vision-based forward collision warning systems with a monocular camera. To solve the problem of variation of camera pitch angle due to vehicle motion and road inclination, the proposed method estimates virtual horizon from size and position of vehicles in captured image at run-time. The proposed method provides robust results even when road inclination v...
