Haptic icons (brief tangible stimuli with associated meanings) are a new way to convey information, but are difficult to design in large quantities due to technological and perceptual constraints. Here, we employ rhythm in combination with frequency and amplitude to systematically produce 84 distinguishable tactile stimuli for use as icons. The set’s large size is made possible by an analysis o...

Preface On commission of the Swedish Road Administration, VTI has made a study of how road surface properties (primarily macrotexture and unevenness) affect rolling resistance and fuel consumption of vehicles. Contact person at the Road Administration has been Per-Erik Westergren. Project leader at VTI has been Rune Karlsson. Ulf Hammarström has initiated the project and has had the role of gen...

Multiple-split air conditioning (MSAC) system has become an attractive form of air-conditioning system for smallsized commercial and residential buildings. For a common room air conditioner, the only factor affecting the performance under a fixed outdoor and indoor condition is load rate of the indoor unit. But for the MSAC system, the indoor units will have quite different working situations u...

The subtle alteration of surface geometry from a fresh to sheared usually results in considerable variation the shear strength jointed rock mass. Through profiling surfaces granite joints before and after tests, an evaluation scheme was newly proposed by determining desirable characteristic index sampling interval measurement order distinguish joint quantitatively. measured data demonstrated th...

Social and economic inequalities are both significant important issues in the study of globalization, while global forces have widened their consequences such as unleashing poverty gender imbalances terms equality. The reasons lie reformulation power associated with burgeoning free-market economies accompanying diffusion instrumental rationality, commoditization, secularism. In contrast to down...

The article shows an algorithm for the numerical study of process bending vibrations a hydro-friction damper disk-type electric train with variable mass and stiffness under harmonic action that occurs when it moves along path periodic butt unevenness.

Modeling of yarn and fiber properties has been a popular topic in the field of textile engineering in recent decades. The common method for fitting models has been to use classical regression analysis, based on the assumptions of data crispness and deterministic relations among variables. However, in modeling practical systems such as cotton spinning, the above assumptions may not hold true. Pr...

[1] Using 456 data sets under bank-full conditions obtained from various sources, the geometric relations, derived in part 1 [Singh et al., 2003], are calibrated and verified using the split sampling approach. The calibration of parameters shows that the change in stream power is not shared equally among hydraulic variables and that the unevenness depends on the boundary conditions to be satisf...

This article explores the unevenness of change between! culture and organizational structures. When school leaders and teachers embrace new systems without enough attention paid to the nature of the conver­ sation, and to the way knowledge is learned among the sk:hool's staff, then the sustaining of sound reforms diminishes drastically. By looking at the reforms Mission Middle School leadership...
