The use of autonomous systems on the wood processing sites forest industries can significantly increase safety, productivity, and efficiency by reducing number monotonous dangerous tasks conducted human labor utilizing heavy machinery. However, machines are challenging difficult to implement in mill yards environment because dynamic complex working environment, partly unstructured processes. in...

Operating machinery while distracted is a dangerous behavior, often habitual, which the source of accidents. Distracted driving in particular has assumed form an epidemic, fueled by ubiquity smartphone usage and tendency to slip into absent-mindedness tedious commutes. Here we show that method capable detecting communicating overarousal trends associated with onset distractions, can pull driver...

In this paper, a product derivation process is described, which is based on specifying customer requirements, features and artifacts in a knowledge base. In such a knowledge base a model about all kinds of variability of a software-intensive systems is represented by using a logicbased representation language. Having such a language, a machinery which interprets the model is defined and activel...

Feature selection is one of the most pervasive problems in pattern recognition. It can be posed as a multiobjective optimisation problem, since, in the simplest case, it involves feature subset cardinality minimisation and performance maximisation. In many problem domains, such as in medical or engineering diagnosis, performance can more appropriately be assessed by ROC analysis, in terms of cl...

The article presents a survey of sensors relevant for mobile robot navigation and their sensing principles. The sensors surveyed include range sensors, inertial systems and positioning systems. There are many applications, from different sectors that could profit from this type of technology: autonomous mobile platforms for materials handling in industry, warehouses, hospitals, etc.; forestry c...

Finger or partial finger amputations are a common occupational hazard seen in laborers handling heavy duty machinery [1]. Sudden loss of finger causes marked psychological trauma to the patient besides varying degrees of functional disability depending upon the extent of trauma and disfigurement [2]. A precisely fitting prosthesis can improve function by restoring normal length, protecting the ...

This article argues that some ostensible advantages of Optimality Theory with Candidate Chains (OT-CC) over classic OT are actually liabilities. OT-CC correctly predicts that Chamorro umlaut occurs only when trigger and target are adjacent. But OT-CC is incompatible with similar phenomena like Central Venetan metaphony, and attempts to modify OT-CC to produce metaphony impair the theory’s handl...

Noise injury in agriculture is a significant yet often unrecognized problem. Many farmers, farm workers, and family members are exposed to noise levels above recommended levels and have greater hearing loss than their non-farming contemporaries. The aim of this study was to gather up-to-date information on farm noise levels and to enhance the quality of information available to assist farmers i...

an understanding of the strength of rice grains as affected by moisture content and temperature is important for analysis and prediction of cracking and/or breakage behavior during handling and processing. further, the magnitude of these properties at various moisture contents and temperatures is needed for the accurate design of milling machinery so that grain damage is minimized. to determine...

The flow of grains through narrow apertures possess an extraordinary challenge: clogging. Strategies to alleviate the effect clogging, such as use external vibration or addition smaller grains, are always part design machinery for handling bulk materials. In this work, we study with numerical simulations adding self-repelling magnetic particles a sample grains. We consider vibrated two-dimensio...
