Kinematic Model for Fixed-Wing Aircraft with Constrained Roll-Rate
Full text linkThe technical report derives a kinematic model of fixed-wing aircraft that is based on constrained roll rate. This new kinematic model can be used for trajectory planning and optimization.Open Restriction set for Item 107501 on 2018-09-14T15:18:35Z with date null by [email protected] by Mirco Theile ([email protected]) on 2018-09-15T15:45:36Z

Multi-Objective Memory Bandwidth Regulation and Cache Partitioning for Multicore Real-Time Systems
Full text linkMemory bandwidth regulation and cache partitioning are widely used techniques for achieving predictable timing in real-time computing systems. Combined with partitioned scheduling, these methods require careful co-allocation of tasks and resources to cores, as task execution times strongly depend on available allocated resources. To address this challenge, this paper presents a 0-1 linear program for task-resource co-allocation, along with a multi-objective heuristic designed to minimize resource usage while guaranteeing schedulability under a preemptive EDF scheduling policy. Our heuristic employs a multi-layer framework, where an outer layer explores resource allocations using Pareto-pruned search, and an inner layer optimizes task allocation by solving a knapsack problem using dynamic programming. To evaluate the performance of the proposed optimization algorithm, we profile real-world benchmarks on an embedded AMD UltraScale+ ZCU102 platform, with fine-grained resource partitioning enabled by the Jailhouse hypervisor, leveraging cache set partitioning and MemGuard for memory bandwidth regulation. Experiments based on the benchmarking results show that the proposed 0-1 linear program outperforms existing mixed-integer programs by finding more optimal solutions within the same time limit. Moreover, the proposed multi-objective multi-layer heuristic performs consistently better than the state-of-the-art multi-resource-task co-allocation algorithm in terms of schedulability, resource usage, number of non-dominated solutions, and computational efficiency
On the Tuber magnatum, Tuber albidum and Tuber rufum author name: Picco vs Pico
No full textThis article presents the results of a research that has been conducted on the surname of the author of the three truffle species Tuber magnatum, T. albidum and T. rufum who in the nomenclatural databases of fungi is listed as “Picco” rather than “Pico” (how he is usually indicated). Drawing upon official documents from the Turin State and University Archives the claim is made that the surname Picco is the correct version. This name can also be found in a contemporary review of the book Melethemata Inauguralia (Picco 1788), as well as in a biographic dictionary of Piedmontese physicians dated back to 1825. Therefore, the officially used indication since Stafleu and Cowan (1983) can be considered to be correct
Dal clivus Scauri al vicus Capitis Africae: gli affreschi della vigna Guglielmina a Roma nei disegni dei Bartoli
Full text linkTwo frescoed room discovered on the Caelian hill during the seventeenth century and reproduced by Pietro Santi Bartoli in four drawings were published by the Comte de Caylus in his Recueil de peintures antiques (Paris, 1757). Their findspot has since been situated in the vineyard of Stefano Guglielmini (also known as the “vigna Guglielmina”), located by Lanciani on the Clivo di Scauro facing the church of SS. Giovanni e Paolo. The first room (plates XXIII, XXIV and XXV of the Recueil), discovered in 1639, became famous in art–historical studies due to the presence of portraits of a Roman family on the vaulted ceiling and due to the controversial interpretation of two lunettes with marine iconography; the second room (plate XXVI in the Recueil), less well known, is decorated with a fresco of three mythological figures, each placed in a rectangular panel.
Following archival research, the author has been able critically to re–examine both the topographical context of the find and the composition of the frescoes. This has led him to reject the traditional conclusions, hitherto conditioned by a misinterpretation of the Recueil made by the antiquary Ridolfino Venuti in the mid–eighteenth century. In the first place, the author has revised the location of Stefano Guglielmini’s vineyard: it should be situated, in his view, not on the Clivo di Scauro but on the road that ascended from the Colosseum to the Navicella. This finding then led in turn to a different topographical distribution of the frescoes: while those of the first room are to be located within the vineyard of S. Gregorio al Celio, the second fresco should be placed in the vigna Guglielmina proper. The identification of four other drawings of Bartoli based on Roman frescoes in the vigna Guglielmina in the collections of RIBA in London and Holkham Hall in Norfolk has permitted the author to understand that this latter fresco was not isolated, but must have formed part of a larger cycle that decorated the interior of a triple–apse room, probably the triclinium of a rich late–antique domus overlooking the ancient vicus Capitis Africa
