Opis:
The subject of this article is to present the beta – regression model, where we assume that one parameter in the model is described as a combination of algebraically independent continuous functions. The proposed beta model is useful when the dependent variable is continuous and restricted to the bounded interval. The parameters are obtained by maximum likelihood estimation. We prove that estimators are consistent and asymptotically normal.

Opis:
Głównym celem artykułu jest identyfikacja i ocena obszarów niezgodności ram luminiowych. W artykule wykorzystano metodę zarządzania jakością, jaką jest analiza FMEA. W wyniku przeprowadzonych badań określono priorytetowe dla badanego produktu niezgodności. Kolejnym etapem było wskazanie działań korygujących. Zastosowanie analizy FMEA pomogło określić przyczyny oraz skutki potencjalnych niezgodności. Wykorzystana metoda pozwoliła zbadać główne błędy występujące podczas produkcji ram aluminiowych.
The main purpose of the article is to identify and assess areas of discrepancies of the aluminum framework. The article uses the method of quality management, which is the FMEA analysis. As a result of the tests carried out using the FMEA method, the noncompliances priority for the tested product was determined. The next stage was the indication of corrective actions. The use of FMEA analysis helped to determine the causes and effects of potential nonconformities. The method also allowed to examine the main errors occurring the production of aluminum frames.

Opis:
The production of stereoscopic motion pictures has been recently getting increasingly popular. To provide the best quality of the resulting image, the parameters controlled must precisely correspond to the values calculated by the stereoscopic image analysis platform or chosen by a camera operator. Currently no integrated system exists, which can provide remote monitoring and control of the parameters of 3D rig and cameras on it. The parameters should be controllable both by the Rig Controller software, tablet application or hand controller. The paper discusses an innovative system for remote control of 3D camera rig created within the Recording of 3D Image (ROS3D) research project. The system controls several parameters of both camera rig - stereo base, convergence and camera lenses - focus distance, aperture and focal length. Several approaches of implementation of a solution for the aforementioned problem are presented and compared. The first proposed approach used custom servo motor controller with CAN bus as the communication interface between connected devices, i.e. Rig Controller board and hand manipulators. Another solution contains a commercial servo motor controller connected to the Rig Controller board via RS232 and commercial hand controller. D-Bus Inter-Process Communication (IPC) system is used to communicate between the servo motor controller drivers and Rig Controller software.

Opis:
The increasing complexity of scientific experiments puts a large number of requirements on the systems, which need to control and monitor the hardware components required for the experiments. This article discusses three different technologies of developing Human Machine Interface (HMÏ) for the Piezo Control System (PCS) developed at the Lodz University of Technology (TUL). The purpose of the PCS system is compensating the detuning of a superconducting accelerating structure caused by the Lorentz force. A set of full-custom HMI operator interface was needed to operate the prototype device. In order to select the technology, which would best suit the requirements; the interface was designed and developed in native Qt, Qt Quick and EPICS. The comparison was made and their advantages and drawbacks are presented.

Opis:
The paper describes an universal module for video stream acquisition from fast cameras with Camera Link interface. The first version of the referenced standard defines three configurations: Base, Medium and Full. The developed module supports all of them achieving transmission speeds up to 5.44 Gb/s for raw image data in the Full configuration. The module is designed according to FPGA Mezzanine Card (FMC) standard and can cooperate with carrier boards containing High-Pin Count (HPC) version of the connector. The module was tested with the TEWS TAMC-641 module.

Opis:
As a result of a growing interest in the xTCA systems by research centers conducting High Energy Physics (HEP) experiments, the PICMG xTCA for Physics Coordinating Committee is developing a new, attractive standards. They are specifically dedicated to control and data acquisition systems of HEP applications. These new specifications define a number of extensions to the Advanced Telecommunications Computing Architecture (ATCA) and Micro Telecommunications Computing Architecture ( μ TCA) standards. The MicroTCA for Physics specification, named MTCA.4, defines some new solutions in order to simplify an application of μ TCA specification in HEP facilities. The most important of them is μ RTM module which can be connected to the Advanced Mezzanine Card (AMC) and provides more usable area and additional I/O connectors at the rear of the shelf. The MTCA.4 also introduces additional channels dedicated for timing and synchronization signals that are available on backplane. Due to the fact that xTCA for Physics is a new specification which has not been officially published, both the AMC and μ RTM modules and the software for the MMC with possibility of μ RTM handling are not yet available. For this reason the preparation of firmware for the Module Management Controller (MMC) for AMC modules compatible with MicroTCA for Physics specification is required. This paper presents a structure of the MMC for the μ TC (MicroTCA-based Controller) board. It also describes the microcontroller software which fulfills the role of the MMC.

Opis:
Takotsubo cardiomiopathy (TTC) (known also as “ampulla cardiomyopathy,” “apical ballooning” or “broken heart syndrome”) is connected with a temporary systolic left ventricular dysfunction without the culprit coronary lesion. Takotsubo cardiomyopathy was first described in 1990 in Japan after octopus trapping pot with a round bottom and narrow neck similar in shape to left ventriculogram in TTC patients. The occurrence of TTC is usually precipitated by a stressful event with a clinical presentation mimicking myocardial infarction: chest pain, ST-T segment elevation or T-wave inversion, a rise in cardiac troponin, and contractility abnormalities in echocardiography. A left ventricular dysfunction is transient and improves within a few weeks. Takotsubo cardiomyopathy typically occurs in postmenopausal women and the postulated mechanism is catecholamine overstimulation. Moreover, the distribution of contractility impairments usually does not correspond with typical region supplied by a single coronary artery. Therefore, the assessment of regional pattern of systolic dysfunction with speckle-tracking echocardiography and automated function imaging (AFI) technique may be important in diagnosis of TTC and may improve our insight into its patophysiology. We described a 55-year-old female teacher with TTC diagnosed after acute psychological stress in workplace. The provoking factor related with occupational stress and pattern of contraction abnormalities documented with AFI technique including basal segments of left ventricle make this case atypical.
