Get PDFStiles, S.S., Letter to Mary Knight, September 20, 1863. MS/52 William Knight Civil War Letters, Box 1, Folder 3. Valdosta State University Archives and Special Collections. 1 PDF and 2 scans. Includes transcript.The letter, dated September 20, 1863, is from Camp Lee and addressed to Mary. The author, identified as S.S. Siles, expresses relief that William has returned home and hopes for his quick recovery. Siles mentions the difficulties faced by women who visit camps to bring their sick husbands home, noting that officers rarely pay them any attention.
Siles laments the poor condition of the tents, which are old and worn, failing to provide adequate shelter from rain. He mentions that the Quarter Master tried but failed to secure new tents in Savannah. The letter also touches on the precarious state of the Confederate army, suggesting that its future may hinge on an upcoming battle in Northern Georgia. Siles fears that a defeat could lead to mass desertions.
The letter describes the men as being very sickly, attributing this to their poor diet of only beef and cornmeal. Siles himself is not in good health, suffering from chest pains and fevers, but continues to perform his duties as an acting Orderly Sergeant. He urges Mary to tell William to write to him and to keep him updated with news
Hydroxyapatite Nanocrystals as Bone Tissue Substitute
No full textNano-science, where the properties of materials are exploited for innovative amazing applications is involved in the size dependent chemical and biological activity of bone substitute materials, which is an indeed fascinating field. The article reviews the synthesis and chemical-physical characteristics of hydroxyapatite nano-crystals which have excellent properties to represent an elective material covering a wide range of applications for bone substitution. We have started from the examination of biogenic bone and tooth hydroxyapatite nanocrystals morphological and chemical-physical characteristics. The highlighted concepts have been used to review the up-to date main new ideas about the preparation of synthetic apatitic bone substitutes mimicking the above biogenic properties among which the nano size is the basis of their self assembly, self mineralization and bone regeneration ability.
High bioreabsorbability and containing foreign ions mimicking bone hydroxyapatite chemical-physical and physiological behavior HA nanocrystals has been described, pointing out the possibilty of using them also to prepare scaffolds with a porosity simulating that of spongy bone and upon which cells can be seeded developing “in vitro autologous bone”. Biologically inspired HA nanocrystals/collagen composites have been reviewed focusing the role of self assembling strategy in conditioning the bone repairing activity of this biomaterial. Furthermore, considering that calcium phosphate/collagen composites are limited to not loading application, the possibility of preparing bio-inspired coating onto the surface of metallic implants has been described as an advantageous approach.
Finally, the surface functionalization of HA nano-crystals with bioactive molecules makes them able to transfer information and to act selectively on the biological environment and can be considered one of the main future challenges for innovative bone substitute materials

A Novel Concurrent Validation Scheme for Hardware Transactional Memory
No full textTransactional memory is a lock-free parallel programming model, which aims at replacing conventional lock-based threaded programming techniques, currently used by multi-core systems. These techniques are difficult to implement and impose unnecessary overheads caused by conservative programming practices. In this thesis, the scalability potential of a transactional memory system, called TMFab, was explored for different numbers of processors and it was concluded that for more than 4 processors the system presents reduced scalability, due to an increase in the validation overhead. In response to this observation, a novel validation scheme was proposed which reduces this overhead, first by allowing multiple transactions to perform their validations and commit operations concurrently, and second by removing the need for broadcasting messages between the active transactions. A distributed shared memory scheme was used to increase the validation and memory access throughput, as well as allow for transactions to commit concurrently on different memory partitions. The two architectures were compared by means of SystemC simulation, and a maximum of 2.5x validation speedup was observed for the modified design, together with a 2.7x reduction in memory access latency. In total, the modified design achieved a maximum execution speedup of 30% over the original, for the benchmarks that were used. Furthermore, the modified system guarantees sequential consistency even in corner case scenarios.Computer EngineeringCircuits and SystemsElectrical Engineering, Mathematics and Computer Scienc
ZAVIČAJNO OPREDJELJENJE S.S. KRANJČEVIĆA
Get PDFHrvatski pjesnik S.S. Kranjčević (1865-1908), iako stvaralac nacionalnih i univerzalnih dimenzija, u određenom broju svojih pjesama iskazivao je na osebujan način svoje zavičajno određenje. Te njegove pjesme prožete snažnim emocijskim nabojima predočavaju njegovo viđenje ondašnje hrvatske nacionalne sudbine na prostoru njegova rodnog grada Senja u kontekstu uskočke tradicije koja je Senjane i Hrvate toliko nadahnjivala slobodarstvom i otporom tuđinskim porobljivačkim nasrtajima.The Croatian poet S.S. Kranjčević (1865-1908), though an author of national and universal dimensions, expressed his own native disposition in a number of his poems. Those of his poems, which are imbued with a strong emotional charge, present his own seeing of the Croatian national desetiny of the time in the area of his native town of Senj, and in the context of the Uskok (fighters against the Venetians and Turks) tradition which so much insipred the inhabitants (of Senj) and Croats in general with the love of freedom and resistance to the foreign enslaving assaults

Thermal-Aware Design and Runtime Management of 3D Stacked Multiprocessors
No full textThe sustained increase in computational performance demanded by next-generation applications drives the increasing core counts of modern multiprocessor systems. However, in the dark silicon era, the performance levels and integration density of such systems is limited by thermal constraints of their physical package. These constraints are more severe in the case of three-dimensional (3D) integrated systems, as a consequence of the complex thermal characteristics exhibited by stacked silicon dies. This dissertation investigates the development of efficient, thermal-aware multiprocessor architectures, and presents methodologies to enable the simultaneous exploration of their thermal and functional behaviour. Chapter 2 examines the efficiency of multiprocessor architectures from the perspective of the the memory hierarchy, and presents techniques that focus on the effective management and transfer of on-chip data in order to minimize the time spent waiting on memory accesses. In the case of shared-memory multiprocessors, this is achieved through the proposed Persistence Selective Caching (PSC) and CacheBalancer schemes that influence what data is stored in on-chip caches, where it is stored, and for how long. This enables the memory hierarchy to adapt to changing execution behaviour, balance resource utilization, and most importantly, reduce the average latency and energy per memory access. Further to this, Chapter 2 presents the Pronto system, which enables efficient data transfers in message-passing multiprocessors by minimizing the role of the processing element in the management of transfers. Pronto effectively decreases the overheads incurred in setting up and managing data transfers, thereby yielding shorter communication latencies. In addition, it also simplifies the semantics of data movement by abstracting implementation details of communications from the programmer, thus enabling transfers to be specified entirely at the task level. The issue of thermal-aware design for 3D Integrated Circuits (IC) using Nagata’s equation – a mathematical representation of the dark silicon problem – is investigated in Chapter 3. Significantly, the chapter explores the thermal design space of 3D ICs in terms of this equation, and proposes a high-level flow to characterize the specific influence of individual design parameters on thermal behaviour of die stacks. The results of this exploration advance the state-of-the-art by providing new insights into the critical role of power density, thermal conductivity and stack construction in the formation of hotspots in 3D ICs. Building on these insights, the Ctherm framework is proposed for the thermal-aware design of multiprocessor systems-on-chip (MPSoC). Ctherm enables the concurrent evaluation of thermal and functional performance of MPSoCs using automatically generated fine-grained area, latency and energy models for system components, and facilitates the exploration of thermal behaviour early in the system design flow. The efficacy of the framework is demonstrated using a number of practical design cases ranging from floorplanning and temperature sensor placement to application tuning. Together, the characterization and the Ctherm framework further our understanding of the thermal behaviour of die stacks, and provide a practical template for the realization of thermal-aware electronic design automation tooling for 3D ICs. The management of thermal issues that arise in 3D MPSoCs at runtime is examined in Chapter 4. Temperature control is typically exercised by means of Dynamic Thermal Management (DTM) which continuously adapt the activity and power dissipation of system components. A significant disadvantage of state-of-the-art DTMs lies in their inability to account for the non-uniform thermal behaviour of die stacks, leading to the ineffective management of temperatures and in degraded system performance. In Chapter 4, a novel 3D Dynamic Voltage Frequency Scaling (DVFS) scheme is proposed that takes these non-uniformities into account within its power management algorithm, effectively maintains operating temperatures within a safe range, and maximizes system performance within the available thermal margins at individual processing elements. Furthermore, the chapter also presents an adaptive routing strategy to decrease the magnitude of thermal gradients in network-on-chip based 3D architectures, by directing traffic along paths of low temperature. The proposed Immediate Neighbourhood Temperature (INT) adaptive routing scheme actively steers interconnect traffic away from regions with thermal hotspots based only on temperature information available in the immediate neighbourhood, relying on the heat transfer characteristics of 3D ICs to avoid the need for a global temperature monitoring network. The consequent spreading of interconnect activity over multiple paths results in balanced thermal profiles, and decreased operating temperatures across the system. Over the course of these chapters, this dissertation explores the critical issues impeding the realization of thermal-aware 3D stacked multiprocessors, and details a multifaceted approach towards addressing the challenges of dark silicon.Microelectronics - Circuits and SystemsElectrical Engineering, Mathematics and Computer Scienc
Real-space Manifestations of Bottlenecks in Turbulence Spectra
No full textAn energy-spectrum bottleneck, a bump in the turbulence spectrum between the inertial and dissipation ranges, is shown to occur in the non-turbulent, one-dimensional, hyperviscous Burgers equation and found to be the Fourier-space signature of oscillations in the real-space velocity, which are explained by boundary-layer-expansion techniques. Pseudospectral simulations are used to show that such oscillations occur in velocity correlation functions in one- and three-dimensional hyperviscous hydrodynamical equations that display genuine turbulence
