Forest roads are the base infrastructure foundation of forestry operations. These roads entail a complex engineering effort because they can cause substantial environmental damage to forests and include a high-cost construction. This study was carried out in four sample sites of Giresun, Trabzon(2) and Artvin Forest Directorate, which is in the Black Sea region of Turkey. The areas have both st...

AbstractBackground. Improvement of quality, decrease of terms and cost of construction are inseparably linked with problems of effective use of bulldozer equipment. Purpose. The most important problem of control tractions modes of the bulldozer is the fullest use of traction opportunities of the machine at the expense of management of work tool. Automatic maintenance of the maximum traction pow...

Tobin reasoned that firms should accumulate more capital when Q > 1 and should draw down their capital stock when Q < 1. That is, net investment in physical capital should depend on where Q is in relation to one. How would one measure Q in the data? Typically this is done by using the value of the stock market in the numerator and data on corporate net worth in the denominator – here net worth ...

We evaluated the abundance of nonnative plants on fuel breaks and in adjacent untreated areas to determine if fuel treatments promote the invasion of nonnative plant species. Understanding the relationship between fuel treatments and nonnative plants is becoming increasingly important as federal and state agencies are currently implementing large fuel treatment programs throughout the United St...

Today visitors often approach the massive pyramids, temples, and obelisks of the ancient Egyptians with wonder and disbelief. The huge blocks of stone used to create these architectural masterpieces were quarried and moved without the aid of modern technologies, and it is diffi cult for us to imagine how such feats of engineering could be accomplished without the aid of cranes, bulldozers, truc...

Target detection is a conventional problem for synthetic aperture radar (SAR) image. The technology of target detection is very useful in striking military targets, such as ship, tanks, armoured personnel carriers, trucks, bulldozers, cannon and howitzers. Discriminating target from clutter is a challenging task in Automatic target detection (ATD) problem. Different types of clutter and their d...
