Data Processing at the Flaw Detector with Combined Multisector Eddy-Current Transducer

There is described data processing at the flaw detector with combined multisectional eddy-current transducer and heterofrequency magnetic field. The application of this method for detecting flaws in rods and pipes under the conditions of significant transverse displacements is described.

Parallel Architecture Prototype for 60 GHz High Data Rate Wireless Single Carrier Receiver

Nowadays a huge attention of the academia and research teams is attracted to the potential of the usage of the 60 GHz frequency band in the wireless communications. The use of the 60GHz frequency band offers great possibilities for wide variety of applications that are yet to be implemented. These applications also imply huge implementation challenges. Such example is building a high data rate transceiver which at the same time would have very low power consumption. In this paper we present a prototype of Single Carrier -SC transceiver system, illustrating a brief overview of the baseband design, emphasizing the most important decisions that need to be done. A brief overview of the possible approaches when implementing the equalizer, as the most complex module in the SC transceiver, is also presented. The main focus of this paper is to suggest a parallel architecture for the receiver in a Single Carrier communication system. This would provide higher data rates that the communication system canachieve, for a price of higher power consumption. The suggested architecture of such receiver is illustrated in this paper,giving the results of its implementation in comparison with its corresponding serial implementation.

Storing Data in the Trial of Complex Technical Products

The article considers the ways of organization of databases for the storage of the results obtained during testing. A new variant of the organization of the data to ensure the ability to write to the database different sets of parameters in the form of chronological series. The required set of parameters depends on the modification of the tested technical installation.

Comparison of Contemporary Protocols for High-speed Data Transport via 10 Gbps WAN Connections

This work is dedicated to comparison of open source as well as proprietary transport protocols for highspeed data transmission via IP networks. The contemporary common TCP needs significant improvement since it was developed as general-purpose transport protocol and firstly introduced four decades ago. In nowadays networks, TCP fits not all communication needs that society has. Caused of it another transport protocols have been developed and successfully used for e.g. Big Data movement. In scope of this research the following protocols have been investigated for its efficiency on 10Gbps links: UDT, RBUDP, MTP and RWTP. The protocols were tested under different impairments such as Round Trip Time up to 400 ms and packet losses up to 2%. Investigated parameters are the data rate under different conditions of the network, the CPU load by sender andreceiver during the experiments, size of feedback data, CPU usage per Gbps and the amount of feedback data per GiByte of effectively transmitted data. The best performance and fair resources consumption was observed by RWTP. From the opensource projects, the best behavior is showed by RBUDP.

Inquérito sobre o reinício da atividade ovariana no pós-parto de vacas leiteiras através da dosagem de progesterona no leite

Com o intuito de determinar o reinício da atividade ovariana no pós-parto em vacas leiteiras, foi realizado um estudo em uma propriedade particular na região de Rio das Pedras, São Paulo. Durante 12 meses, amostras de leite foram coletadas semanalmente e o teor de progesterona determinado através de radioimunoensaio. Observou-se que 26,6% das vacas permaneceram em anestro e que ocorreram falhas nas observações de cio. A maioria dos animais (61,1%) apresentou atividade ovariana com 31 à 60 dias de pós-parto.

Reinício da atividade ovariana no pós-parto em vacas holandesas do rebanho da ESALQ

Foram determinados os perfis de progesterona no leite desnatado, em 32 vacas da raça Holandesa no pós-parto até a primeira ovulação no período de 1986 e 1987. A linha divisória das fases folicular e luteínica dos teores de progesterona foi estimada em l,12mg/ml. Ficou evidenciado que não há diferença no tempo da primeira ovulação no pós-parto (36,83 ± 18,92 dias) para vacas holandesas criadas em clima tropical ou temperado.
