The physics base for the ITER Physics Design Guidelines is reviewed in view of application to DEMO and areas are pointed out which improvement needed arrive at a consistent set Guidelines. Amongst proposed improvements, area power exhaust plays crucial role since predictive capability present-day models low this expected play major limiting designs due much larger value Ptot/R than devices even ITER.
The standard loader (ld.so) is a common target of attacks. trusted component the application, and faults in are problematic, e.g., they may lead to local privilege escalation for SUID binaries. Software-based fault isolation (SFI) provides framework execute arbitrary code while protecting host system. A problem current approaches SFI that decoupled from dynamic loader, which treated as black box. sandbox has no information about (expected) execution behavior application connections between...
Abstract As a convenient alternative to the classical melt polycondensation one‐pot solution of suitable AB 2 monomers under mild conditions has been successfully adapted hyperbranched all‐aromatic polyester with phenol terminal groups. The polymerization was performed in at room temperature directly using commercially available 3,5‐dihydroxybenzoic acid as monomer and 4‐(dimethylamino) pyridinium 4‐tosylate catalyst suppress formation N ‐acylurea. Different carbodiimides coupling agents...
Dendronization of a hyperbranched polyester with different generation dendrons leads to pseudo-dendritic structures. The core is modified by the divergent coupling protected monomer units functional groups. Compared dendrimers, synthetic effort significantly less, but properties are very close those high-generation dendrimers. number groups, molar mass, and rheology behavior even in early (G1-G4) pseudo-dendrimers strongly resembles dendrimers higher generations (G5-G8). Comparison segmental...
A pseudo-dendritic structure clear of linear units is obtained from a hyperbranched aliphatic-aromatic polyester core modified by B-protected AB(2) monomer. The chosen sequence reaction and deprotection steps yields four generations pseudo-dendrimers with either silyl- or OH-terminal units. (1)H (13)C NMR confirm the extent modification degree branching in different generations. influence generation number, end group type, on specific solution behavior investigated size-exclusion...
Managed runtime environments (MREs) like web browsers or the Java Virtual Machine (JVM) include multiple dynamic compilers (or compiler configurations) to provide a good tradeoff between compilation speed and generated code quality: Longer times typically imply better quality hence peak performance than shorter times, which warmup/startup lower performance. A system that uses is referred as multi-tiered system.
The Java®HotSpot Virtual Machine includes a multi-tier compilation system that may invoke compiler at any time. Lower tiers instrument the program to gather information for highly optimizing top tier, and this bases its optimizations on these profiles. But if assumptions made by top-tier are proven wrong (e.g., because profile does not cover all execution paths), method is deoptimized: code generated discarded then executed Tier 0 again. Eventually, after has been gathered, recompiled tier...
In the automotive industry, petrochemical plastics are widespread because glass and carbon fiber-reinforced composites consist exclusively of petroleum-based matrix materials. So far, bio-based couldn’t meet requirement profile due to their high prices, inappropriate features ineligible quality assurance synthesis. But development new polyamides opens opportunity replace may initiate use plastic matrices for applications.In this study, short polyamide 10.10 were investigated. Short fibers...
This paper describes the basic concepts of error diagnostics and an associated rule system whose application helps to identify potential hardware/software locations errors which caused a failure observed while executing tests embedded systems. Further on, overview over "Avionics Smoke Detection System" is given, where main algorithms have been applied. The methods, techniques tools described here rely on preceding investigations performed with respect signal flow observation causal chains in...
In this work we summarize the results of long-term ageing different medium voltage outdoor power equipment in an artificial climatic chamber and compare them with obtained at a natural site Koeberg Insulator Pollution Test Station near Cape Town, South Africa. The show that by correctly adjusting cycle consisting UV radiation, heat, clean salt fog it is possible to age accelerated rate (a factor 5 greater) obtain same type damage (UV damage, tracking erosion due surface discharges, cracking)...
Abstract Die Dendronisierung von hochverzweigten Polyestern mit Dendronen unterschiedlicher Generationen führt zu pseudo‐dendritischen Strukturen. Der hochverzweigte Kern wurde durch divergente Kopplung geschützten Monomereinheiten an die funktionellen Gruppen modifiziert. Verglichen Dendrimeren ist der präparative Aufwand hier deutlich geringer; Eigenschaften sind höherer jedoch sehr ähnlich. Anzahl Gruppen, Molmasse und das rheologische Verhalten (G5–G8) wird schon Pseudo‐Dendrimeren...
Pseudo-Dendrimere. Ein Polyesterkern, der mit Dendronen unterschiedlicher Generation modifiziert wurde, weist typische Eigenschaften perfekt verzweigter Dendrimere auf. A. Lederer et al. beschreiben diesen neuen Typ von Pseudo-Dendrimer in ihrer Zuschrift auf S. 12764 ff.
In this paper, the author explains a new approach of model based end-to-end chain testing using scenarios with original and simulated equipment. The first goal is to automatically derive test data cases from model, which defined by domain specific language. Several solvers can be attached conversion quickly create wide variety stimuli for system(s) under test. Furthermore, system stimulated either equipment - connected bench or simulate inputs tested systems. Any mixture possible changed on...
