It is well accepted that Garbage Collection simpliies programming, promotes modularity, and reduces development eeort. However it is commonly believed that these advantages do not counteract the price that has to be paid: excesive overheads, possible long pause times, and the need of modifying existing code. Even though there exist publically available garbage collectors that can be used in exi...

nappropriately designed classroom furniture that does not take children’s anthropometric measurements into account has a negative effect on musculoskeletal systems. In this study, which kept Covid-19 pandemic policies in mind, students’ static dimensions were measured and their descriptive statistics calculated, using mean, standard deviation, percentiles, statistical tests, including the t-tes...

In recent year’s reversible logic has been considered as an important issue for designing low power digital circuits. It has voluminous applications in the present rising nanotechnology such as DNA computing, Quantum Computing, low power VLSI and quantum dot automata. In this paper we have proposed optimized design of reversible sequential circuits in terms of number of gates, delay and hardwar...

In this paper, we deal with the effects of urban landscapes on land prices under uncertainty, represented by fuzzy numbers. To this end, the factors for evaluating urban landscapes are designed using fuzzy numbers. Moreover, we consider 11 factors for utilizing the approach, like as Continuity of external walls, Conformity of colors and materials, Favorable pedestrian space, Decorations and str...

Cats are often thought to be the cleanest of companion animals so most owners find it distressing and unacceptable when their cat urinates inappropriately on the carpet or sprays the furniture. Elimination problems are the most common behavioural problem reported in cats, accounting for 40-75% of behavioural problems cats (Pryor et al., 2001; Seksel, 2000). While inappropriate elimination is no...

It is generally accepted that delineating and enforcing property rights lead to a more efficient use of private property. Thai farmers with secure title, for example, are estimated to be 12-27 percent more productive than their untitled counterparts (Feder 1988). In urban areas the focus has been on the role of security of tenure in enhancing property values and incentives to invest in housing ...
