Microprocessor training bench
The paper presents a new microprocessor training bench on a modern microcontroller STM 32F303VC with ARM core family of Cortex M4. A distinctive feature of the bench is a built-in peripheral equipment to convert the analog input signal with a large range of voltages into digital form with the highest possible sampling, as well as a digital output that can be used for various applications, including high-current to control the actuators provided appropriate conversion devices. The powerful core prints stand to the category of high-performance data acquisition, data processing, diagnostics and control, automation of production processes and researchΠ ΡΡΠ°ΡΡΠ΅ ΠΏΡΠ΅Π΄ΡΡΠ°Π²Π»Π΅Π½ Π½ΠΎΠ²ΡΠΉ ΡΡΠ΅Π±Π½ΡΠΉ ΠΌΠΈΠΊΡΠΎΠΏΡΠΎΡΠ΅ΡΡΠΎΡΠ½ΡΠΉ ΡΡΠ΅Π½Π΄, ΠΏΠΎΡΡΡΠΎΠ΅Π½Π½ΡΠΉ Π½Π° ΡΠΎΠ²ΡΠ΅ΠΌΠ΅Π½Π½ΠΎΠΌ ΠΌΠΈΠΊΡΠΎΠΊΠΎΠ½ΡΡΠΎΠ»Π»Π΅ΡΠ΅ STM 32F303VC Ρ ΡΠ΄ΡΠΎΠΌ ARM ΡΠ΅ΠΌΠ΅ΠΉΡΡΠ²Π° Cortex M4.

DEVELOPMENT OF MULTIFUNCTIONAL DEVICE FOR MONITORING HUMAN VITAL SIGNS. BIOPOTENTIALS AND TEMPERATURE MEASUREMENT

Constraints on Type Ia Supernova Models from X-ray Spectra of Galaxy Clusters
We present constraints on theoretical models of Type Ia supernovae using
spatially resolved ASCA X-ray spectroscopy of three galaxy clusters: Abell 496,
Abell 2199 and Abell 3571. All three clusters have central iron abundance
enhancements; an ensemble of abundance ratios are used to show that most of the
iron in the central regions of the clusters comes from SN Ia. These
observations are consistent with the suppressed galactic wind scenario proposed
by Dupke and White (1999). At the center of each cluster, simultaneous analysis
of spectra from all ASCA instruments shows that the nickel to iron abundance
ratio (normalized by the solar ratio) is Ni/Fe ~ 4. We use the nickel to iron
ratio as a discriminator between SN Ia explosion models: the Ni/Fe ratio of
ejecta from the "Convective Deflagration" model W7 is consistent with the
observations, while those of "delayed detonation" models are not consistent at
the 90% confidence level.Comment: 20 pages, 2 figures, accepted by The Astrophysical Journa
