Abstract Key message Structural characteristics of tree crowns obtained by TLidar scanning can be used for estimating the course stem diameter growth in past. To improve human well-being through sustainable management ecosystems, particular attention is given to structures, functions, and services forest trees stands. The classical timber provision has become only one many other ecosystem servi...

The availability of repeatable dynamic rollover fixtures, like the Controlled Rollover Impact System (CRIS) and Jordan Rollover System (JRS), has changed the face of rollover structural and occupant protection development and evaluation. Tests performed with these devices have demonstrated scientific principles of occupant protection and injury potential which were previously resolvable only by...

This paper presents a new framework for recovering superquadrics with global deformations from multi-view real range data. The framework aims at improving confidence and accuracy of recovered models by utilizing multiview information, and consists of the initial superquadric model recovery, view registration, view integration, and final model recovery from integrated data. A quadrant analysis t...

In order to identify physical model parameters of a high-rise building, a new story stiffness identification method is presented based on a shear-bending model and the identification function. Although a shear building model may be the simplest conventional model for representing tall buildings, the system identification (SI) method using that model is not necessarily appropriate. This is becau...

This article presents the design of a miniaturized wearable patch antenna to be utilized for body area network (BAN) applications. To reduce size crown fractal geometry technique has been adopted, and which resulted in reduction 26.85%. Further, polyester cloth has used as substrate make proposed flexible one, suitable biomedical devices. The designed functions 2.45 GHz ISM band gain bandwidth ...

To effectively optimize the mechanical behavior of a traditional anti-slide pile and reduce environmental destruction, new method for slope reinforcement by spatial arc crown beam composite supporting structure was proposed. First, numerical model validated through lab-scale test data obtained herein, then full-scale created an in-depth understanding distribution regularity displacement along p...

in this work, laser bending of perforated sheets has been investigated numerically. laser bending of perforated sheets is more complicated than non-perforated sheets due to their complex geometries. in this paper, laser bending of perforated sheets is studied numerically in the form of thermo-mechanical analysis with abaqus/implicit code. for this purpose, the effects of process and sheet param...

the most important postharvest disorder of cut gerbera is stem bending disorder, which occurs below the capitulum. stem strength and lignification is one of important phenomenon and causes of gerbera stem bending. therefore, this experiment was conducted to evaluate the effects of salicylic acid (sa) on phenylalanine ammonia-lyase enzyme activity (pal), as an important enzyme in phenylpropanoid...

Tire-derived aggregate (TDA) has been used successfully as a backfill soil to reduce the applied stresses on buried steel pipes. The preceding study, however, paid no attention inspecting TDA efficiency of concrete pipes subjected and traffic loads. In addition, it is not clear how material, loading, burial depth, road section affect pipe-bending moment. Therefore, this paper examines in reduci...

the complexation reactions between tl+ and pb2+ ions and crown ethers 12-crown-4(12c4), 15-crown-5 (15c5), benzo-15-crown-5 (b15c5), 18-crown-6 (18c6), dicyclohexyl-18-crown-6 (dc18c6) and aza-18-crown-6 (a18c6) were studied in 90% acetonitrile and 90% ethanol solutions at 25 °c, using an a.c. polarographic technique. the stoichiometry and stability of the complexes were determined by monitorin...
