Lambert S Problem

based on the intractability of the discrete logarithm problem. Although the authors had no practical realization of a public-key encryption scheme at the time, the idea was clear and it generated extensive interest and activity in the cryptographic community. In 1978 Rivest, Shamir, and Adleman discovered the first practical public-key encryption and signature scheme, now referred to as RSA. The RSA scheme is based on another hard mathematical problem, the intractability of factoring…

soils limits food production in annual cropping systems. Because some tropical soils under natural conditions have high biological activity, an increased use of the biological potential of these soils to counter the challenges of food production problems is proposed. Most plant species (including the major crops in the tropics) form beneficial associations with arbuscular mycorrhizal (AM) fungi. These fungi could be the most important and poorly understood resource for nutrient…

Cat´ lica do Paran´ (PUCPR) ı o a Rua Imaculada Conceicao 1155 CEP 80215-901 ¸˜ Curitiba - PR, Brasil ABSTRACT PMV-MBPC Algorithms for Thermal Comfort: An Application to a Test-cell The present paper is focused on thermal comfort control problem for building occupants. Thermal comfort is a concept difficult to define and, here, the PMV (Predicted Mean Vote) index is used by means of two predictive control strategies, characterized by having terminal constraints, called here…

negligenciando a complexidade do reservatório oceânico, a biomassa continental é menos acessível do que os oceanos à modelagem e à reunião de medidas que possam levar à conclusão ou não que a vegetação terrestre é um depósito do excesso de CO2 atmosférico (LAMBERT, 1987, p. 784). Em meio a esta discussão, torna-se importante mencionar os satélites de observação que podem ajudar muito na elucidação da problemática do CO2. Porém, fazer a correspondência das imagens de satélite em relação…

domestic violence also are mandated reporters. In addition, community-based agency staff, clergy, extended family members, and concerned citizens play important roles in supporting and keeping families safe. Domestic violence is a devastating social problem that affects every segment of the population. While system responses are primarily targeted towards adult victims of abuse, increasing attention is now focused on the children who witness domestic violence.1 Studies estimate that 10…

2010 Abstract: Many carboxylic molecules, ranging from drugs to flavors and fragrances, contain chiral centers. As a consequence, research has been carried out in order to design and synthesize artificial receptors for carboxylic anions. Many problems have to be solved for binding anions. The results obtained in the binding of carboxylic anions by guanidine, secondary ammonium and metal-center have been selected. The last part of this review focuses on chiral recognition of carboxylic…

the objective of evaluating performance measurement systems. The goal is to make a contribution for the development of such systems (focusing on costing systems) directed to the supplychain management. In order to comply with this objective, the problem is introduced and positioned within the research lines of department. In addition, performance measurement concepts are introduced, supply-chain performance indicators are characterized and finally, an approach to costing system in…
