Dynamic Thermal Modeling and Application of Electrical Machine in Hybrid Drives

This paper presents a holistic view of thermal modeling for an electrical machine used in a Hybrid Electrical Vehicle (HEV). This interconnected system model focuses on the thermal assessment of an electrical machine in a HEV application and estimates the time to failure of the machine depending on the construction of the insulation system and the exploitation of the machine. A transient thermal m

A Method for Finding the Maximal Set in Excess Demand

We present a polynomial time method for identifying the maximal set in excess demand at a given payoff vector. This set can be used in "large" partnership formation problems to identify the minimum element in the set of individually rational payoff vectors at which there is no overdemanded set of agents. This minimum element corresponds to the minimum Walrasian equilibrium price vector in a specia

Fragmentation of molecules and clusters after resonant excitation of core electrons

A study highlighting several aspects of resonant spectroscopies where fragmentation processes are investigated is described. We focus primarily on understanding the dynamical processes taking place in core-excited states in molecules. An example where fast dissociation and molecular alignment are discussed is given for the ammonia molecule.

Miniaturized, Membrane-Based and Environmentally Green Sample Preparation Systems: Applications for Biological and Environmental Aqueous Samples

Contemporary advancements in miniaturization of analytical systems have advantageously fostered development, automation, and hyphenation of a variety of sample preparation techniques. Among several downscaled extraction designs, porous synthetic polymeric membranes (such as flat sheet (FS) or hollow fiber (HF)) have been utilized for membrane-based extraction, separating two aqueous phases (as in

Radiography and bone scintigraphy in osteoarthritis of the knee: comparison with MR imaging

Popular Abstract in Swedish Röntgen och isotopundersökning vid knäledsartros: en jämförelse med magnetkamera-undersökning Denna avhandling utgör en del av ett större forskningsprojekt om tidig artros (s.k. broskförslitning) i knäleden. Studien omfattar nästan 200 personer med knäsmärta, som när projektet startade 1990 var mellan 35 och 54 år. Vår avsikt är att under minst 10 års tid regelbundet uThe aim was to compare radiography of the tibiofemoral joint (TFJ) and the patellofemoral joint (PFJ), as well as bone scinigraphy with MR imaging in middle-aged individuals with chronic knee pain in the format of a prospective study of knee osteoarthritis. Individuals aged 35-54 years with chronic knee pain were identified. The prevalence of chronic knee pain was 15% (279/2000). Within this grou

Ultra low energy vs throughput design exploration of 65 nm sub-VT CMOS digital filters

This paper presents an analysis on energy dissipation of a digital half band filters operated in the the sub-threshold (sub-VT ) region with throughput constraints. The degradation of speed in the sub-VT domain is counteracted by unfolding the architectures. A filter is implemented in a basic 12-bit and its various unfolded structures. The designs are synthesized in a 65 nm low-leakage high-thresh
