Das SPI-Modell dient zur Repräsentation von heterogenen eingebetteten Systemen. Basierend auf diesem Modell wurde in einem Forschungsverbund zwischen der TU Braunschweig, der Universität Erlangen-Nürnberg und der ETH Zürich die systemweite Analyse und Optimierung eingebetteter Systeme untersucht und in der SPI-Workbench integriert. Besonderes Augenmerk wurde auf die domänenübergreifende Integra...

Agile software development has challenged the traditional ways of delivering software as it provides a very different approach to software development. In recent decades, software process improvement (SPI) has been widely studied in the context of traditional software development, and its strengths and weaknesses have been recognised. As organisations increasingly adopt agile software developme...

PU.1 (the Spi-1 oncogene) and Spi-B are closely related members of the ets transcription factor family, sharing similar DNA binding specificities mediated by similar DNA binding domains. PU.1 and Spi-B have been previously described as being predominantly expressed coordinately in macrophages and B cells, but their expression in early hematopoietic stages and during the course of myeloid differ...

OBJECTIVE The objective of this study was to evaluate effects of heat treatment and soybean oil inclusion on protein oxidation of soy protein isolate (SPI) and of oxidized protein on redox status of broilers at an early age. METHODS SPI mixed with soybean oil (SPIO) heated at 100°C for 8 h was used to evaluate protein oxidation of SPI. A total of two hundred and sixteen 1-day-old Arbor Acres ...

A symbol permutation invariant balanced (SPI-balanced) code over the alphabet Zm = {0, 1, . . . , m − 1} is a block code over Zm such that each alphabet symbol occurs as many times as any other symbol in every codeword. For this reason every permutation among the symbols of the alphabet changes a SPI-balanced code into a SPI-balanced code. This means that SPI-balanced words are “the most balanc...

Endogenous estrogens are important determinants of breast cancer risk in postmenopausal women. In this study we evaluated the effects of dietary soy isoflavonoids on endogenous estrogen metabolism in a postmenopausal primate model. Ovariectomized female cynomolgus monkeys were randomized to receive one of three diets for 36 months: (i) isoflavonoid-depleted soy protein isolate (SPI-) (n = 29); ...

Existing software engineering and management literature argue for many different ways of looking at success factors that influence Software Process Improvement (SPI). This study investigates success factors identified in a number of research projects and proposes a model for managing these factors in a structured way during different phases of an SPI program. It also aspires to describe a model...

Background Serine protease inhibitors (SPI) comprising 60-90 amino acid residues, are frequent in plants, and belong to the protein family PR-6. It has recently been shown that a SPI-variant of wheat acts as an important allergen in baker’s asthma but not in persons suffering from wheatinduced food allergy. The aim of this study was to elucidate the role of a recombinant SPI-variant of Hevea br...

Eighty patients undergoing elective ear-nose-throat surgery were enrolled in the present study to investigate the relationship between surgical pleth index (SPI) and stress hormones (ACTH, cortisol, epinephrine, norepinephrine) during general anaesthesia which was induced and maintained with propofol and remifentanil using a target-controlled infusion. The study concluded that the SPI had moder...

The spectrometer SPI is one of the main detectors of ESA’s INTEGRAL mission. The instrument offers two interesting and valuable capabilities for the detection of the prompt emission of Gamma-ray bursts. Within a field of view of 16 degrees, SPI is able to localize Gamma-ray bursts with an accuracy of 10 arcmin. The large anticoincidence shield, ACS, consisting of 512 kg of BGO crystals, detects...
