This paper describes the ROLLENT system submitted to the Eight International Planning Competition, Learning Track. ROLLENT combines two machine learning techniques: generation of entanglements and decision tree learning by ROLLER. Entanglements capture causal relationships for a class of problems while ROLLER learns relational decision trees useful to sort the applicable operators at a given st...
Mechanistic pavement design procedures based on elastic layer theory require characterization of all pavement layer materials including subgrade soil. This paper discusses the subgrade stiffness obtained from a new compaction device called the Intelligent Compaction (IC) roller on highway embankment projects in Kansas. Three test sections on two routes were compacted using a single, smooth stee...
Introduction: The TC system, developed in 2002, allows the endodontic filling by means of a non-conventional technique that uses gutta-percha at alpha phase, thermoplasticized in its own oven, placed into canal through a McSpadden compactor, without using a main cone. Objective: The aim of this case report was to show the TC system used for root canal filling. Case report: Three teeth of a pati...
This paper is concerned with optimization of process parameters for a roller leveller that is an indispensable equipment to eliminate the undesirable curvature of a thin-walled aluminum pipe. Optimization of process parameters has been carried out for a multistaggered-type 14-roller leveller. A finite element model of a multi-staggered 14-roller leveller was constructed for analysis whose resul...
[Purpose] This study aims to examined the effect of the self-myofascial release induced with a foam roller on the reduction of stress by measuring the serum concentration of cortisol. [Subjects and Methods] The subjects of this study were healthy females in their 20s. They were divided into the experimental and control groups. Both groups, each consisting of 12 subjects, were directed to walk f...
and Implications The aim of this study was to test if further grinding of corn DDGS is advantageous in terms of apparent total tract digestibility (ATTD) of DM, GE, nitrogen (N), and NDF in growing and finishing pigs. It was also tested to determine if ATTD was different between hammermill and roller mill grinding methods. There were 3 diets. Each diet consisted of 51% corn ground at 500 micron...
This paper concerns the tension control of roll-to-roll systems. In such systems, each driven roller speed is controlled separatly. The impact of the master roller position on tension control performances is studied using optimized web tension control synthesis. The tension disturbance rejection property and the system robustness regarding web elasticity variations are analysed for each configu...
Burnishing is cold working process where hard roller are being pressed against irregular surface, so that surface finish and the micro hardness increases. In this study internal roller burnishing tool is used to burnish the drilled hole. Speed, feed, and number of passes have been varied using taguchi method to examine the surface finish and microhardness. Anova analysis is carried out. Surface...
BACKGROUND Human monocyte-derived DC (mDC) loaded with peptides, protein, tumor cell lysates, or tumor cell RNA, are being tested as vaccines against multiple human malignancies and viral infection with great promise. One of the factors that has limited more widespread use of these vaccines is the need to generate mDC in large scale. Current methods for the large-scale cultivation of mDC in sta...
Article history: Received: 08.11.2013. Received in revised form: 12.01.2013. Accepted: 14.01.2014. The grinding roller shaft is a key part of the grinding roller. It has a step-shaped shaft with different round cross-sections and 1850 mm × 1110 mm rectangular cross-section. If the general method of free forging is used, the upsetting diameter of ingot will reach 2900 mm, and 8400 t hydraulic pr...
