ion in AI and CS In the early days of CS, algorithms were often seen as an abstract formulation of procedures. Nowadays, this workshop illustrates well that category theory is associated to an abstract formulation of CS. The example of computer algebra teaches us that such methodologies do not amount to a full abstraction paradigm. Giunchiglia and Walsh introduced theories of abstraction for me...

The successful establishment of agricultural crops depends on sowing quality, machinery performance, soil type and conditions, among other factors. This study evaluates the operational quality of mechanized peanut sowing in three soil types (sand, silt, and clay) with variable moisture contents. The experiment was conducted in three locations in the state of São Paulo, Brazil. The track-samplin...

A major barrier to more common use of mechanical theorem provers in verifying software designs is the signi cant distance between proof styles natural to humans and proof styles supported by mechanical provers. To make mechanical provers useful to software designers with some mathematical sophistication but without expertise in mechanical provers, the distance between hand proofs and their mech...

in this paper, a mechanized system for self-assessment based on process-oriented approach of iso 9004:2000 has been developed. to design of this mechanized system, the expert system has been used as in providing the assessment and scoring questions the experts’ knowledge, head auditors of quality management system, has been used and this knowledge has been saved in the access software database....

The current Amazon landscape consists of heterogeneous mosaics formed by interactions between the original forest and productive activities. Recognizing and quantifying the characteristics of these landscapes is essential for understanding agricultural production chains, assessing the impact of policies, and in planning future actions. Our main objective was to construct the regionalization of ...

this study was conducted to reveal the impact of rural-urban migration on broiler production in the niger delta region of nigeria. data were collected from 795 household heads and farmers/managers/supervisors of 25 selected broiler farms in the study area. descriptive statistics and multiple regression analysis was utilized to analyze the data. able bodied young men constituted most of the rura...

In mechanized timber harvesting, it is common practice to build brush mats from logging residues on skid trails. Protective effects of brush mats against soil compaction are documented by several studies. On the other hand, a large quantity of nutrients is concentrated on the skid trail. Fully mechanized harvesting has been criticized frequently for this reallocation of nutrients. Is there real...
