Cartografia da Guerra Guaranítica

The Guaranitic War (1753-1756) was the warlike event set off by the rebellious Indians against the demarcators and armies of Spain and Portugal. It was motivated by the rejection of six cabildos (Fundamental unit of local government in colonial Latin America) located east of Uruguay River, chief of Misiones and Jesuitical, upon contesting clauses of the Treaty of Madrid (1750). The main cause was the forecast of exchange of the Seven Peoples (Spanish) by the Colony of the Sacrament (Portuguese). This event produced considerable cartography. The conferences for the signature of the Treaty of Madrid, equally, promoted intense systematization of the existing cartography and the output of exclusive works about the regions of borders. In his corollary, cartography for the commissioner demarcators were organized. And, in the boundary work, the teams illustrated the dividing and the territories. In special, the divergent areas were written up to the details. In that process, there were created a cartography and an iconography of the war. It was specified to territoriality, the geography, the battles, the military marches, the missionary cities and their architecture. In this work, we privilege the cartographic/iconographic production of the missionary space representation, of the first commission of limits and of the Guaranitic War. All of the documents cited are reproduced, with the references to the collections, in my book The Guaranitic War (GOLIN, 1998) and The Frontier (GOLIN, 2002)

A estatuária como cultura material constitutiva de espacialidades nas áreas rurais missioneiras

Este artigo trata da estatuária como cultura material constitutiva de espaços nas áreas rurais das doutrinas fundadas por jesuíticas e indígenas na América meridional. Considera-se a complexidade da criação desses contornos em sua significância relacional e sua remanescência. As regiões que abrangiam as antigas estâncias e chácaras missioneiras conservam imagens em madeira que pertenceram a capelas e ermidas espalhadas pelos postos e assentamentos campesinos. A permanência desse fragmento da cultura material, que compunha e caracterizava os espaços missionais, somada às referências encontradas na documentação primária e às contribuições teórico-metodológicas fundamentadas na ótica da espacialidade, problematizada por Tilley (1994) e Santos (2014), conduzirão as aproximações com os sentidos e condicionantes da construção dos espaços extra doutrinas, agenciado por indígenas

Finding optimal paths in MREP routing

Maximum Residual Energy Path (MREP) routing has been shown an effective routing scheme for energy conservation in battery powered wireless networks. Past studies on MREP routing are based on the assumption that the transmitting node consumes power, but the receiving node does not. This assumption is false if acknowledgment is required as occurs, for example, in some Bluetooth applications. If the receiving node does not consume power then the MREP routing problem for a single message is easily solvable in polynomial time using a simple Dijkstra-like algorithm. We further show in that when the receiving node does consume power the problem becomes NP-complete and is even impossible to approximate with an exponential approximation factor in polynomial time unless P = NP

Maximum residual energy routing with reverse energy cost

Abstract-The Maximum Residual Energy Path (MREP) routing has been shown an effective routing scheme for energy conservation in a battery wireless network. Past studies on MREP are based on the assumption that the transmitting node consumes power, but the receiving node does not. This assumption is false if acknowledgement is required, or if the ad hoc network has deployed the energy-conservation mode (sleeping mode). When backward energy consumption is present in transmission (i.e. the receiving end consumes energy), finding an MRE path that has enough energy for finishing the transmission has become NP-hard. We show in this paper a Dijkstra-like heuristic algorithm for finding the optimal MRE path. The new algorithm guarantees that once a path is found, it will have enough energy to finish the transmission task, while the original MREP algorithm, ignoring the backward energy costs, cannot guarantee that. We also show another routing technique that can extend the system life. The technique works for both MREP-based routing schemes. I
