This paper aims at finding a subclass of DTDs that covers many of the real-world DTDs while offering a polynomial-time complexity for deciding the XPath satisfiability problem. In our previous work, we proposed RW-DTDs, which cover most of the real-world DTDs (26 out of 27 real-world DTDs and 1406 out of 1407 DTD rules). However, under RW-DTDs, XPath satisfiability with only child, descendant-o...

Body measurements and performance results were collected from 193 equids participating in the 1998 Western States Trail Ride's 100-mile endurance race, commonly known as the Tevis Cup. Age of equids (horses, mules and ponies) were 5 to 21 years and body condition scores (CS) (NRC, 1989) ranged from 2.5 to 5.5. Equids were assessed for CS 11 to 18 hours prior to the race. Rider weight and tack (...

Field Editor: M. Frese Effective human capital formation through the medium of entrepreneurship education and training (EET) is of increasing concern for governments, as EET is growing rapidly across the world. Unfortunately, there is a lack of consistent evidence showing that EET helps to create more or better entrepreneurs. We undertake the first quantitative review of the literature and, in ...

Mineral wools are the most common insulation materials in buildings worldwide. However, mineral wool waste is often considered unrecyclable because of its fibrous nature and low density. In this paper, rock wool (RW) and glass wool (GW) were studied as alkali-activated material precursors without any additional co-binders. Both mineral wools were pulverized by a vibratory disc mill in order to ...

In this paper, a novel W-band substrate integrated waveguide (SIW) power combiner/divider is analyzed theoretically and demonstrated experimentally/numerically, based on the antipodal fin-line SIW-rectangular waveguide (SIW-RW) transition and longitudinal slot coupling techniques. This antipodal fin-line SIW-RW transition can work at the frequency band of 86.4GHz– 106.1GHz with return loss larg...

The effectiveness of refinery wastewater (RW) treatment using air-cathode, microbial fuel cells (MFCs) was examined relative to previous tests based on completely anaerobic microbial electrolysis cells (MECs). MFCs were configured with separator electrode assembly (SEA) or spaced electrode (SPA) configurations to measure power production and relative impacts of oxygen crossover on organics remo...

Pallo and Wu et al. respectively introduced the left-weight sequences (LW-sequences) and right-weight sequences (RW-sequences) for representing binary trees. In this paper, we introduce two new types of binary tree sequences called the left-child sequences (LC-sequences) and right-child sequences (RC-sequences). Next, we propose a loopless algorithm associated with rotations of binary trees for...

We introduce the Read-Write-Coding-System (RWC) – a very flexible class of MDS codes using a variation of Reed-Solomon (RS) codes, but offer enhanced possibilities to update any codeword, and to adjust the redundancy and thus, the fault-tolerance capability of the code. In particular, given a message x of length k, a block code y of length n and arbitrarily chosen parameters k ≤ r, w ≤ n, our R...
